  • Linux Books For Windows/C++ Programmers?

    - by John Dibling
    I'm a Windows C++ programmer with a great deal of experience, and I'm looking for book recommendations to get up to speed with programming in Linux (specifically RHE 6). Ideally, I'd like a book geared specifically to my needs. Something along the lines of "Linux C++ Programming for Windows Experts" would be nice. :) I'm open to any recommendations you have. My domain is primarily financial market data servers (no GUIs) and simple console apps. I do a lot of multithreading, a lot of networking, not a lot of user interface stuff. I know C++0x, but our production codebase can only use C++. Thanks for your recommendations for books and/or resources!

  • Fresh install 12.04 Performance & Stability: SONY VPCCW2S1E

    - by George Katsanos
    just yesterday I installed 12.04. Is it normal that installing a package (Chrome for example) takes 5 to 10 minutes (compared to Windows 7 for example which takes 2 or 3)? (with end result: installation failed) Otherwise is it normal that while the system is doing some installation,extracting packs and so on, other applications often become unresponsive? Sidenote: I don't care about fancy desktop effects, I installed ubuntu to go on and experiment with web servers, memcache, Varnish and git/svn. So basically I plan to do lots of console-only operations. My surprise was also the difference of stability compared to an old FreeBSD installation I had on a dinosaur P3 550Mhz :) (I am on a SONY VPCCW2S1E) (I guess it might have to do something with my problems?)

  • Some notes on Reflector 7

    - by CliveT
    Both Bart and I have blogged about some of the changes that we (and other members of the team) have made to .NET Reflector for version 7, including the new tabbed browsing model, the inclusion of Jason Haley's PowerCommands add-in and some improvements to decompilation such as handling iterator blocks. The intention of this blog post is to cover all of the main new features in one place, and to describe the three new editions of .NET Reflector 7. If you'd simply like to try out the latest version of the beta for yourself you can do so here. Three new editions .NET Reflector 7 will come in three new editions: .NET Reflector .NET Reflector VS .NET Reflector VSPro The first edition is just the standalone Windows application. The latter two editions include the Windows application, but also add the power of Reflector into Visual Studio so that you can save time switching tools and quickly get to the bottom of a debugging issue that involves third-party code. Let's take a look at some of the new features in each edition. Tabbed browsing .NET Reflector now has a tabbed browsing model, in which the individual tabs have independent histories. You can open a new tab to view the selected object by using CTRL+CLICK. I've found this really useful when I'm investigating a particular piece of code but then want to focus on some other methods that I find along the way. For version 7, we wanted to implement the basic idea of tabs to see whether it is something that users will find helpful. If it is something that enhances productivity, we will add more tab-based features in a future version. PowerCommands add-in We have also included Jason Haley's PowerCommands add-in as part of version 7. This add-in provides a number of useful commands, including support for opening .xap files and extracting the constituent assemblies, and a query editor that allows C# queries to be written and executed against the Reflector object model . All of the PowerCommands features can be turned on from the options menu. We will be really interested to see what people are finding useful for further integration into the main tool in the future. My personal favourite part of the PowerCommands add-in is the query editor. You can set up as many of your own queries as you like, but we provide 25 to get you started. These do useful things like listing all extension methods in a given assembly, and displaying other lower-level information, such as the number of times that a given method uses the box IL instruction. These queries can be extracted and then executed from the 'Run Query' context menu within the assembly explorer. Moreover, the queries can be loaded, modified, and saved using the built-in editor, allowing very specific user customization and sharing of queries. The PowerCommands add-in contains many other useful utilities. For example, you can open an item using an external application, work with enumeration bit flags, or generate assembly binding redirect files. You can see Bart's earlier post for a more complete list. .NET Reflector VS .NET Reflector VS adds a brand new Reflector object browser into Visual Studio to save you time opening .NET Reflector separately and browsing for an object. A 'Decompile and Explore' option is also added to the context menu of references in the Solution Explorer, so you don't need to leave Visual Studio to look through decompiled code. We've also added some simple navigation features to allow you to move through the decompiled code as quickly and easily as you can in .NET Reflector. When this is selected, the add-in decompiles the given assembly, Once the decompilation has finished, a clone of the Reflector assembly explorer can be used inside Visual Studio. When Reflector generates the source code, it records the location information. You can therefore navigate from the source file to other decompiled source using the 'Go To Definition' context menu item. This then takes you to the definition in another decompiled assembly. .NET Reflector VSPro .NET Reflector VSPro builds on the features in .NET Reflector VS to add the ability to debug any source code you decompile. When you decompile with .NET Reflector VSPro, a matching .pdb is generated, so you can use Visual Studio to debug the source code as if it were part of the project. You can now use all the standard debugging techniques that you are used to in the Visual Studio debugger, and step through decompiled code as if it were your own. Again, you can select assemblies for decompilation. They are then decompiled. And then you can debug as if they were one of your own source code files. The future of .NET Reflector As I have mentioned throughout this post, most of the new features in version 7 are exploratory steps and we will be watching feedback closely. Although we don't want to speculate now about any other new features or bugs that will or won't be fixed in the next few versions of .NET Reflector, Bart has mentioned in a previous post that there are lots of improvements we intend to make. We plan to do this with great care and without taking anything away from the simplicity of the core product. User experience is something that we pride ourselves on at Red Gate, and it is clear that Reflector is still a long way off our usual standards. We plan for the next few versions of Reflector to be worked on by some of our top usability specialists who have been involved with our other market-leading products such as the ANTS Profilers and SQL Compare. I re-iterate the need for the really great simple mode in .NET Reflector to remain intact regardless of any other improvements we are planning to make. I really hope that you enjoy using some of the new features in version 7 and that Reflector continues to be your favourite .NET development tool for a long time to come.

  • How to Play PC Games on Your TV

    - by Chris Hoffman
    No need to wait for Valve’s Steam Machines — connect your Windows gaming PC to your TV and use powerful PC graphics in the living room today. It’s easy — you don’t need any unusual hardware or special software. This is ideal if you’re already a PC gamer who wants to play your games on a larger screen. It’s also convenient if you want to play multiplayer PC games with controllers in your living rom. HDMI Cables and Controllers You’ll need an HDMI cable to connect your PC to your television. This requires a TV with HDMI-in, a PC with HDMI-out, and an HDMI cable. Modern TVs and PCs have had HDMI built in for years, so you should already be good to go. If you don’t have a spare HDMI cable lying around, you may have to buy one or repurpose one of your existing HDMI cables. Just don’t buy the expensive HDMI cables — even a cheap HDMI cable will work just as well as a more expensive one. Plug one end of the HDMI cable into the HDMI-out port on your PC and one end into the HDMI-In port on your TV. Switch your TV’s input to the appropriate HDMI port and you’ll see your PC’s desktop appear on your TV.  Your TV becomes just another external monitor. If you have your TV and PC far away from each other in different rooms, this won’t work. If you have a reasonably powerful laptop, you can just plug that into your TV — or you can unplug your desktop PC and hook it up next to your TV. Now you’ll just need an input device. You probably don’t want to sit directly in front of your TV with a wired keyboard and mouse! A wireless keyboard and wireless mouse can be convenient and may be ideal for some games. However, you’ll probably want a game controller like console players use. Better yet, get multiple game controllers so you can play local-multiplayer PC games with other people. The Xbox 360 controller is the ideal controller for PC gaming. Windows supports these controllers natively, and many PC games are designed specifically for these controllers. Note that Xbox One controllers aren’t yet supported on Windows because Microsoft hasn’t released drivers for them. Yes, you could use a third-party controller or go through the process of pairing a PlayStation controller with your PC using unofficial tools, but it’s better to get an Xbox 360 controller. Just plug one or more Xbox controllers into your PC’s USB ports and they’ll work without any setup required. While many PC games to support controllers, bear in mind that some games require a keyboard and mouse. A TV-Optimized Interface Use Steam’s Big Picture interface to more easily browse and launch games. This interface was designed for using on a television with controllers and even has an integrated web browser you can use with your controller. It will be used on the Valve’s Steam Machine consoles as the default TV interface. You can use a mouse with it too, of course. There’s also nothing stopping you from just using your Windows desktop with a mouse and keyboard — aside from how inconvenient it will be. To launch Big Picture Mode, open Steam and click the Big Picture button at the top-right corner of your screen. You can also press the glowing Xbox logo button in the middle of an Xbox 360 Controller to launch the Big Picture interface if Steam is open. Another Option: In-Home Streaming If you want to leave your PC in one room of your home and play PC games on a TV in a different room, you can consider using local streaming to stream games over your home network from your gaming PC to your television. Bear in mind that the game won’t be as smooth and responsive as it would if you were sitting in front of your PC. You’ll also need a modern router with fast wireless network speeds to keep up with the game streaming. Steam’s built-in In-Home Streaming feature is now available to everyone. You could plug a laptop with less-powerful graphics hardware into your TV and use it to stream games from your powerful desktop gaming rig. You could also use an older desktop PC you have lying around. To stream a game, log into Steam on your gaming PC and log into Steam with the same account on another computer on your home network. You’ll be able to view the library of installed games on your other PC and start streaming them. NVIDIA also has their own GameStream solution that allows you to stream games from a PC with powerful NVIDIA graphics hardware. However, you’ll need an NVIDIA Shield handheld gaming console to do this. At the moment, NVIDIA’s game streaming solution can only stream to the NVIDIA Shield. However, the NVIDIA Shield device can be connected to your TV so you can play that streaming game on your TV. Valve’s Steam Machines are supposed to bring PC gaming to the living room and they’ll do it using HDMI cables, a custom Steam controller, the Big Picture interface, and in-home streaming for compatibility with Windows games. You can do all of this yourself today — you’ll just need an Xbox 360 controller instead of the not-yet-released Steam controller.

  • Maintaining packages with code - Adding a property expression programmatically

    Every now and then I've come across scenarios where I need to update a lot of packages all in the same way. The usual scenario revolves around a group of packages all having been built off the same package template, and something needs to updated to keep up with new requirements, a new logging standard for example.You'd probably start by updating your template package, but then you need to address all your existing packages. Often this can run into the hundreds of packages and clearly that's not a job anyone wants to do by hand. I normally solve the problem by writing a simple console application that looks for files and patches any package it finds, and it is an example of this I'd thought I'd tidy up a bit and publish here. This sample will look at the package and find any top level Execute SQL Tasks, and change the SQL Statement property to use an expression. It is very simplistic working on top level tasks only, so nothing inside a Sequence Container or Loop will be checked but obviously the code could be extended for this if required. The code that actually sets the expression is shown below, the rest is just wrapper code to find the package and to find the task. /// <summary> /// The CreationName of the Tasks to target, e.g. Execute SQL Task /// </summary> private const string TargetTaskCreationName = "Microsoft.SqlServer.Dts.Tasks.ExecuteSQLTask.ExecuteSQLTask, Microsoft.SqlServer.SQLTask, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"; /// <summary> /// The name of the task property to target. /// </summary> private const string TargetPropertyName = "SqlStatementSource"; /// <summary> /// The property expression to set. /// </summary> private const string ExpressionToSet = "@[User::SQLQueryVariable]"; .... // Check if the task matches our target task type if (taskHost.CreationName == TargetTaskCreationName) { // Check for the target property if (taskHost.Properties.Contains(TargetPropertyName)) { // Get the property, check for an expression and set expression if not found DtsProperty property = taskHost.Properties[TargetPropertyName]; if (string.IsNullOrEmpty(property.GetExpression(taskHost))) { property.SetExpression(taskHost, ExpressionToSet); changeCount++; } } } This is a console application, so to specify which packages you want to target you have three options: Find all packages in the current folder, the default behaviour if no arguments are specified TaskExpressionPatcher.exe .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Find all packages in a specified folder, pass the folder as the argument TaskExpressionPatcher.exe C:\Projects\Alpha\Packages\ .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Find a specific package, pass the file path as the argument TaskExpressionPatcher.exe C:\Projects\Alpha\Packages\Package.dtsx The code was written against SQL Server 2005, but just change the reference to Microsoft.SQLServer.ManagedDTS to be the SQL Server 2008 version and it will work fine. If you get an error Microsoft.SqlServer.Dts.Runtime.DtsRuntimeException: The package failed to load due to error 0xC0011008… then check that the package is from the correct version of SSIS compared to the referenced assemblies, 2005 vs 2008 in other words.

When: September 12, 2012 8:30am – 5:00pm Where: Boston Marriott Burlington One Burlington Mall Road Burlington, MA 01803 Register now Agenda Time Session Title Room 8:30 am - 9:00 am Registration and Continental Breakfast Salon E Foyer 9:00 am - 9:15 am Welcome and Opening Comments | Bob Rhubart Salon E 9:15 am - 10:00 am Engineered Systems: Oracle's Vision for the Future | Ralf Dossmann Oracle's Exadata and Exalogic are impressive products in their own right. But working in combination they deliver unparalleled transaction processing performance with up to a 30x increase over existing legacy systems, with the lowest cost of ownership over a 3 or 5 year basis than any other hardware. In this session you'll learn how to leverage Oracle's Engineered Systems within your enterprise to deliver record-breaking performance at the lowest TCO. Salon E 10:00 am - 10:30 am Securing Public and Private Clouds | Anton Nielsen Long before the term "Cloud Computing" existed, Oracle technologies supported and promoted the concept. Centralized data with remote users has been at the core of these technologies for decades. The public cloud, and extending private clouds to the internet, though, has added security challenges never imagined decades ago. This presentation will examine a real life security breach and introduce architecture, technologies and policies to secure public and private clouds.  Salon E 10:30 am - 10:45 am Break 10:45 am - 11:30 am Breakout Sessions (pick one) Cloud Computing - Making IT Simple | Scott Mattoon The road to Cloud Computing is not without a few bumps. This session will help to smooth out your journey by tackling some of the potential complications. We'll examine whether standardization is a prerequisite for the Cloud. We'll look at why refactoring isn't just for application code. We'll check out deployable entities and their simplification via higher levels of abstraction. And we'll close out the session with a look at engineered systems and modular clouds. Salon E Innovations in Grid Computing with Oracle Coherence | Rob Misek Learn how Coherence can increase the availability, scalability and performance of your existing applications with its advanced low-latency data-grid technologies. Also hear some interesting industry-specific use cases that customers had implemented and how Oracle is integrating Coherence into its Enterprise Java stack. Salon C 11:30 am - 12:15 pm Breakout Sessions (pick one) Enterprise Strategy for Cloud Security | Dave Chappelle Security is high on the list of concerns for many organizations as they evaluate their cloud computing options. This session will examine security in the context of the various forms of cloud computing. We'll consider technical and non-technical aspects of security, and discuss several strategies for cloud computing, from both the consumer and producer perspectives. Salon E Oracle Enterprise Manager | Avi Huber Much more than a DB management tool, Oracle Enterprise Manager provides management and monitoring coverage for the entire Oracle stack, and beyond. This session will concentrate on the middleware management functionality in OEM, starting with Real User Experience monitoring, through AppServer management, and into deep-dive Java diagnostics. We’ll discuss Business Driven Application Management (BDAM) and the benefits of top-down monitoring. Lastly, we’ll demonstrate how to trace a specific user experience problem, through a multitier SOA application, to its root cause, deep in the JVM. Salon C 12:15 pm - 1:15 pm Lunch Salon E Foyer 1:15 pm - 2:00 pm Panel Discussion - Q&A with session speakers Salon E 2:00 pm - 2:45 pm Breakout Sessions (pick one) Oracle Cloud Reference Architecture | Anbu Krishnaswamy Cloud initiatives are beginning to dominate enterprise IT roadmaps. Successful adoption of Cloud and the subsequent governance challenges warrant a Cloud reference architecture that is applied consistently across the enterprise. This presentation will answer the important questions: What exactly is a Cloud, why you need it, what changes it will bring to the enterprise, and what are the key capabilities of a Cloud infrastructure are - using Oracle's Cloud Reference Architecture, which is part of the IT Strategies from Oracle (ITSO) Cloud Enterprise Technology Strategy (ETS). Salon E 21st Century SOA | Peter Belknap Service Oriented Architecture has evolved from concept to reality in the last decade.

  • Problems with opening CHM Help files from Network or Internet

    - by Rick Strahl
    As a publisher of a Help Creation tool called Html Help Help Builder, I’ve seen a lot of problems with help files that won't properly display actual topic content and displays an error message for topics instead. Here’s the scenario: You go ahead and happily build your fancy, schmanzy Help File for your application and deploy it to your customer. Or alternately you've created a help file and you let your customers download them off the Internet directly or in a zip file. The customer downloads the file, opens the zip file and copies the help file contained in the zip file to disk. She then opens the help file and finds the following unfortunate result:     The help file  comes up with all topics in the tree on the left, but a Navigation to the WebPage was cancelled or Operation Aborted error in the Help Viewer's content window whenever you try to open a topic. The CHM file obviously opened since the topic list is there, but the Help Viewer refuses to display the content. Looks like a broken help file, right? But it's not - it's merely a Windows security 'feature' that tries to be overly helpful in protecting you. The reason this happens is because files downloaded off the Internet - including ZIP files and CHM files contained in those zip files - are marked as as coming from the Internet and so can potentially be malicious, so do not get browsing rights on the local machine – they can’t access local Web content, which is exactly what help topics are. If you look at the URL of a help topic you see something like this:   mk:@MSITStore:C:\wwapps\wwIPStuff\wwipstuff.chm::/indexpage.htm which points at a special Microsoft Url Moniker that in turn points the CHM file and a relative path within that HTML help file. Try pasting a URL like this into Internet Explorer and you'll see the help topic pop up in your browser (along with a warning most likely). Although the URL looks weird this still equates to a call to the local computer zone, the same as if you had navigated to a local file in IE which by default is not allowed.  Unfortunately, unlike Internet Explorer where you have the option of clicking a security toolbar, the CHM viewer simply refuses to load the page and you get an error page as shown above. How to Fix This - Unblock the Help File There's a workaround that lets you explicitly 'unblock' a CHM help file. To do this: Open Windows Explorer Find your CHM file Right click and select Properties Click the Unblock button on the General tab Here's what the dialog looks like:   Clicking the Unblock button basically, tells Windows that you approve this Help File and allows topics to be viewed.   Is this insecure? Not unless you're running a really old Version of Windows (XP pre-SP1). In recent versions of Windows Internet Explorer pops up various security dialogs or fires script errors when potentially malicious operations are accessed (like loading Active Controls), so it's relatively safe to run local content in the CHM viewer. Since most help files don't contain script or only load script that runs pure JavaScript access web resources this works fine without issues. How to avoid this Problem As an application developer there's a simple solution around this problem: Always install your Help Files with an Installer. The above security warning pop up because Windows can't validate the source of the CHM file. However, if the help file is installed as part of an installation the installation and all files associated with that installation including the help file are trusted. A fully installed Help File of an application works just fine because it is trusted by Windows. Summary It's annoying as all hell that this sort of obtrusive marking is necessary, but it's admittedly a necessary evil because of Microsoft's use of the insecure Internet Explorer engine that drives the CHM Html Engine's topic viewer. Because help files are viewing local content and script is allowed to execute in CHM files there's potential for malicious code hiding in CHM files and the above precautions are supposed to avoid any issues. © Rick Strahl, West Wind Technologies, 2005-2012 Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • Which Java web framework do you recommend for intranet webapp (not content website)?

    - by pregzt
    I'm about to start development of small purpose build intranet web application for small software vendor. It will be administration console of the server managing licenses for off-the-shelf software installed by users. There will be a few users who need to be able to sign in, issue a batch of license codes, revoke some, renew outdated, resolve issues, etc. Bear in mind that my customer requires Java for this solution. I'm seasoned Java programmer and before I used different frameworks to implement webapps, mainly Apache Struts in the past and Spring MVC recently. I was wondering what else could you recommend for such specific intranet webapp. I looked at using Google Web Toolkit (possibly with SmartGWT) Ext JS for fancy widgets in UI and REST back-end in SpringMVC SpringMVC with JQueryUI Could you please think of any piece of recommendation with regard to the choice I'm going to made?

  • Trouble switching to Dvorak on Ubuntu 12.04

    - by Dodgie
    I've decided to switch to Dvorak on my Ubuntu machine, but I'm having some trouble: First, I attempted to do this through the GUI -- System Settings - Keyboard Layout - add layout (plus sign) - English(programmer Dvorak). This didn't work at first, so I restarted my machine. It seemed to work at the password prompt (if only because QWERTY did not), but I couldn't get it to accept my password. I used the virtual keyboard option to enter my password with mouse clicks (the virtual keyboard was using the programmer's Dvorak Standard) and was able to get in that way. Once logged in, however, I was back to QWERTY. Second, I tried to switch on the command prompt -- $ loadkeys /usr/lib/kbd/keytables/dvorak.map The error message I received was "Couldn't get a file descriptor referring to the console " Does anyone know what I'm doing wrong? I've looked for a solution for these problems, but couldn't find anything.

  • Why is my Ubuntu system not using the correct kernel?

    - by Brooks Moses
    We're having a bit of confusion on a Ubuntu remote system -- /boot/grub/menu.lst suggests the system should boot into kernel 2.6.35-30-generic, but it is actually running kernel 2.6.32-27-generic.

  • Kubuntu login problem

    - by Balázs Mária Németh
    I have a problem when trying to login to my Kubuntu 10.10. The login screen shows up, then I type my password, a blank screen is shown with my desktop background picture and then throws me back on the login screen. if I choose to login from console, I can do that, and by typing startx I can log in just fine but in the end I cannot shutdown the computer from the k menu nor will my settings remembered for the next time I log back. I have my home directory mounted from a different partition but I tried to create a new user account and I could log in without any kind of problem. The home directory is not encrypted, at least not to my knowledge. Some log files: Xorg.0.log dmesg.out kdm.log xsession.errors

  • Compute if a function is pure

    - by Oni
    As per Wikipedia: In computer programming, a function may be described as pure if both these statements about the function hold: The function always evaluates the same result value given the same argument value(s). The function result value cannot depend on any hidden information or state that may change as program execution proceeds or between different executions of the program, nor can it depend on any external input from I/O devices. Evaluation of the result does not cause any semantically observable side effect or output, such as mutation of mutable objects or output to I/O devices. I am wondering if it is possible to write a function that compute if a function is pure or not. Example code in Javascript: function sum(a,b) { return a+b; } function say(x){ console.log(x); } isPure(sum) // True isPure(say) // False

  • Why does my Ubuntu freeze in the middle of something with a blank screen?

    - by mohamed
    I am facing a serious problem as my Dell Optiplex 745 loaded with Ubuntu 12.04 32bit freezes with a blank screen no mouse cursor no keyboard activity in many occasions. Sometimes when I open firefox, or software center, I really can't tell what the main problem is, but what i am certain about is it i have to do a hard reset to reboot. I tried to use a live-cd to boot but it did the same, tried the recovery console but couldn't find a way to fix from there (I am a new user) suspected a hardware problem but windows runs flawlessly so I believe its something related to ubuntu.

  • An update process that is even worse than Windows updates

    - by fatherjack
    I'm sorry EA but your game update process stinks. I am not a hardcore gamer but I own a Playstation3 and have been playing Battlefield Bad Company 2 (BFBC2) a bit since I got it for my birthday and there have been two recent updates to the game. Now I like the idea of games getting updates via downloadable content. You can buy a game and if there are changes that are needed (service packs if you will) then they can be distributed over the games console network. Great. Sometimes it fixes problems,...(read more)

  • How To Get Web Site Thumbnail Image In ASP.NET

    - by SAMIR BHOGAYTA
    Overview One very common requirement of many web applications is to display a thumbnail image of a web site. A typical example is to provide a link to a dynamic website displaying its current thumbnail image, or displaying images of websites with their links as a result of search (I love to see it on Google). Microsoft .NET Framework 2.0 makes it quite easier to do it in a ASP.NET application. Background In order to generate image of a web page, first we need to load the web page to get their html code, and then this html needs to be rendered in a web browser. After that, a screen shot can be taken easily. I think there is no easier way to do this. Before .NET framework 2.0 it was quite difficult to use a web browser in C# or VB.NET because we either have to use COM+ interoperability or third party controls which becomes headache later. WebBrowser control in .NET framework 2.0 In .NET framework 2.0 we have a new Windows Forms WebBrowser control which is a wrapper around old shwdoc.dll. All you really need to do is to drop a WebBrowser control from your Toolbox on your form in .NET framework 2.0. If you have not used WebBrowser control yet, it's quite easy to use and very consistent with other Windows Forms controls. Some important methods of WebBrowser control are. public bool GoBack(); public bool GoForward(); public void GoHome(); public void GoSearch(); public void Navigate(Uri url); public void DrawToBitmap(Bitmap bitmap, Rectangle targetBounds); These methods are self explanatory with their names like Navigate function which redirects browser to provided URL. It also has a number of useful overloads. The DrawToBitmap (inherited from Control) draws the current image of WebBrowser to the provided bitmap. Using WebBrowser control in ASP.NET 2.0 The Solution Let's start to implement the solution which we discussed above. First we will define a static method to get the web site thumbnail image. public static Bitmap GetWebSiteThumbnail(string Url, int BrowserWidth, int BrowserHeight, int ThumbnailWidth, int ThumbnailHeight) { WebsiteThumbnailImage thumbnailGenerator = new WebsiteThumbnailImage(Url, BrowserWidth, BrowserHeight, ThumbnailWidth, ThumbnailHeight); return thumbnailGenerator.GenerateWebSiteThumbnailImage(); } The WebsiteThumbnailImage class will have a public method named GenerateWebSiteThumbnailImage which will generate the website thumbnail image in a separate STA thread and wait for the thread to exit. In this case, I decided to Join method of Thread class to block the initial calling thread until the bitmap is actually available, and then return the generated web site thumbnail. public Bitmap GenerateWebSiteThumbnailImage() { Thread m_thread = new Thread(new ThreadStart(_GenerateWebSiteThumbnailImage)); m_thread.SetApartmentState(ApartmentState.STA); m_thread.Start(); m_thread.Join(); return m_Bitmap; } The _GenerateWebSiteThumbnailImage will create a WebBrowser control object and navigate to the provided Url. We also register for the DocumentCompleted event of the web browser control to take screen shot of the web page. To pass the flow to the other controls we need to perform a method call to Application.DoEvents(); and wait for the completion of the navigation until the browser state changes to Complete in a loop. private void _GenerateWebSiteThumbnailImage() { WebBrowser m_WebBrowser = new WebBrowser(); m_WebBrowser.ScrollBarsEnabled = false; m_WebBrowser.Navigate(m_Url); m_WebBrowser.DocumentCompleted += new WebBrowserDocument CompletedEventHandler(WebBrowser_DocumentCompleted); while (m_WebBrowser.ReadyState != WebBrowserReadyState.Complete) Application.DoEvents(); m_WebBrowser.Dispose(); } The DocumentCompleted event will be fired when the navigation is completed and the browser is ready for screen shot. We will get screen shot using DrawToBitmap method as described previously which will return the bitmap of the web browser. Then the thumbnail image is generated using GetThumbnailImage method of Bitmap class passing it the required thumbnail image width and height. private void WebBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { WebBrowser m_WebBrowser = (WebBrowser)sender; m_WebBrowser.ClientSize = new Size(this.m_BrowserWidth, this.m_BrowserHeight); m_WebBrowser.ScrollBarsEnabled = false; m_Bitmap = new Bitmap(m_WebBrowser.Bounds.Width, m_WebBrowser.Bounds.Height); m_WebBrowser.BringToFront(); m_WebBrowser.DrawToBitmap(m_Bitmap, m_WebBrowser.Bounds); m_Bitmap = (Bitmap)m_Bitmap.GetThumbnailImage(m_ThumbnailWidth, m_ThumbnailHeight, null, IntPtr.Zero); } One more example here : http://www.codeproject.com/KB/aspnet/Website_URL_Screenshot.aspx

  • Using GParted to rescue data and format hard drive to NTFS

    - by Ishan
    I'm having problems booting to Windows XP due to bad sectors on the hard drive. I've tried fixboot and fixmbr from the recovery console. That only made matters worse. Now I want to use GParted to attempt data rescue and format the hard drive to NTFS. Unfortunately, I get an error (Picture 2) when trying to recover my files, and the option to format the hard drive is grayed out. The only thing I can do is create a new partition. When I click "view" I get the "Unable to open the default file manager" error

  • Test case as a function or test case as a class

    - by GodMan
    I am having a design problem in test automation:- Requirements - Need to test different servers (using unix console and not GUI) through automation framework. Tests which I'm going to run - Unit, System, Integration Question: While designing a test case, I am thinking that a Test Case should be a part of a test suite (test suite is a class), just as we have in Python's pyunit framework. But, should we keep test cases as functions for a scalable automation framework or should be keep test cases as separate classes(each having their own setup, run and teardown methods) ? From automation perspective, Is the idea of having a test case as a class more scalable, maintainable or as a function?

  • Sony steps back from Linux?

    - by EmbeddedInsider
    In Cnet today I saw something interesting: According to Sony, it plans to release PlayStation 3 firmware version 3.21 on Thursday to achieve one goal: eliminate the "Other OS" option currently available in all pre-Slim models of the video game console. The feature allowed PS3 owners to install an operating system--in almost every case, Linux--onto the PlayStation 3. No surprise. l  Sony is a company heavily invested with legacy IP (games, all that music and Blueray).  They know that content can be nowhere near the GPL. http://news.cnet.com/8301-13506_3-10471356-17.html?tag=rtcol;pop

  • Implications of Java 6 End of Public Updates for EBS Users

    - by Steven Chan (Oracle Development)
    The Support Roadmap for Oracle Java is published here: Oracle Java SE Support Roadmap The latest updates to that page (as of Sept. 19, 2012) state (emphasis added): Java SE 6 End of Public Updates Notice After February 2013, Oracle will no longer post updates of Java SE 6 to its public download sites. Existing Java SE 6 downloads already posted as of February 2013 will remain accessible in the Java Archive on Oracle Technology Network. Developers and end-users are encouraged to update to more recent Java SE versions that remain available for public download. For enterprise customers, who need continued access to critical bug fixes and security fixes as well as general maintenance for Java SE 6 or older versions, long term support is available through Oracle Java SE Support . What does this mean for Oracle E-Business Suite users? EBS users fall under the category of "enterprise users" above.  Java is an integral part of the Oracle E-Business Suite technology stack, so EBS users will continue to receive Java SE 6 updates after February 2013. In other words, nothing will change for EBS users after February 2013.  EBS users will continue to receive critical bug fixes and security fixes as well as general maintenance for Java SE 6. These Java SE 6 updates will be made available to EBS users for the Extended Support periods documented in the Oracle Lifetime Support policy document for Oracle Applications (PDF): EBS 11i Extended Support ends November 2013 EBS 12.0 Extended Support ends January 2015 EBS 12.1 Extended Support ends December 2018 Will EBS users be forced to upgrade to JRE 7 for Windows desktop clients? No. This upgrade will be highly recommended but currently remains optional. JRE 6 will be available to Windows users to run with EBS for the duration of your respective EBS Extended Support period.  Updates will be delivered via My Oracle Support, where you can continue to receive critical bug fixes and security fixes as well as general maintenance for JRE 6 desktop clients.  The certification of Oracle E-Business Suite with JRE 7 (for desktop clients accessing EBS Forms-based content) is in its final stages.  If you plan to upgrade your EBS desktop clients to JRE 7 when that certification is released, you can get a head-start on that today. Coexistence of JRE 6 and JRE 7 on Windows desktops The upgrade to JRE 7 will be highly recommended for EBS users, but some users may need to run both JRE 6 and 7 on their Windows desktops for reasons unrelated to the E-Business Suite. Most EBS configurations with IE and Firefox use non-static versioning by default. JRE 7 will be invoked instead of JRE 6 if both are installed on a Windows desktop. For more details, see "Appendix B: Static vs. Non-static Versioning and Set Up Options" in Notes 290801.1 and 393931.1. Applying Updates to JRE 6 and JRE 7 to Windows desktops Auto-update will keep JRE 7 up-to-date for Windows users with JRE 7 installed. Auto-update will only keep JRE 7 up-to-date for Windows users with both JRE 6 and 7 installed.  JRE 6 users are strongly encouraged to apply the latest Critical Patch Updates as soon as possible after each release. The Jave SE CPUs will be available via My Oracle Support.  EBS users can find more information about JRE 6 and 7 updates here: Information Center: Installation & Configuration for Oracle Java SE (Note 1412103.2) The dates for future Java SE CPUs can be found on the Critical Patch Updates, Security Alerts and Third Party Bulletin.  An RSS feed is available on that site for those who would like to be kept up-to-date. What will Mac users need? Oracle will provide updates to JRE 7 for Mac OS X users. EBS users running Macs will need to upgrade to JRE 7 to receive JRE updates. The certification of Oracle E-Business Suite with JRE 7 for Mac-based desktop clients accessing EBS Forms-based content is underway. Mac users waiting for that certification may find this article useful: How to Reenable Apple Java 6 Plug-in for Mac EBS Users Will EBS users be forced to upgrade to JDK 7 for EBS application tier servers? No. This upgrade will be highly recommended but will be optional for EBS application tier servers running on Windows, Linux, and Solaris.  You can choose to remain on JDK 6 for the duration of your respective EBS Extended Support period.  If you remain on JDK 6, you will continue to receive critical bug fixes and security fixes as well as general maintenance for JDK 6. The certification of Oracle E-Business Suite with JDK 7 for EBS application tier servers on Windows, Linux, and Solaris as well as other platforms such as IBM AIX and HP-UX is planned.  Customers running platforms other than Windows, Linux, and Solaris should refer to their Java vendors's sites for more information about their support policies.

  • LAMP Stack Location

    - by Artem Moskalev
    I have installed the LAMP stack on Ubuntu 12.04 LTS using the tasksel command. I checked - it works. But I cant find the location of the installaton, I worked with WAMP - there you have a separate folder for Apache, for PHP and for mysql. Now I cant even find where to put the documents I create. Which folder is used to contain my web projects? How to start MySQL console and where to look for its installation directory? Which directories are PHP and Apache installed in? how to erase LAMP stack? I found out that some of the parts of the stack are installed in the root/var and root/etc directories: How can I install the whole LAMP stack in /home?

  • Closing the gap between strategy and execution with Oracle Business Intelligence 11g

    - by manan.goel(at)oracle.com
    Wikipedia defines strategy as a plan of action designed to achieve a particular goal. An example of this is General Electric's acquisitions and divestiture strategy (plan) designed to propel GE to number 1 or 2 place (goal) in every business segment that it operated in. Execution on the other hand can be defined as the actions taken to getting things done. In GE's case execution will be steps followed for mergers/acquisitions or divestiture. Business press has written extensively about the importance of both strategy and execution in achieving desired business objectives. Perhaps the quote from Thomas Edison says it best - "vision without execution is hallucination". Conversely, it can be said that "execution without vision" is well may be "wishful thinking". Research overwhelmingly point towards the wide gap between strategy and execution. According to a published study, 49% of surveyed executives perceive a gap between their organizations' ability to develop and communicate sound strategies and their ability to implement those strategies. Further, of these respondents, 64% don't have full confidence that their companies will be able to close the gap. Having established the severity and importance of the problem let's talk about the reasons for the strategy-execution gap. The common reasons include: -        Lack of clearly defined goals -        Lack of consistent measure of success -        Lack of ownership -        Lack of alignment -        Lack of communication -        Lack of proper execution -        Lack of monitoring       There are multiple approaches to solving the problem including organizational development practices, technology enablement etc. In most cases a combination of approaches is required to achieve the desired result. For the purposes of this discussion, I'll focus on technology.  Imagine an integrated closed loop technology platform that automates the entire management cycle from defining strategy to assigning ownership to communicating goals to achieving alignment to collaboration to taking actions to monitoring progress and achieving mid course corrections. Besides, for best ROI and lowest TCO such a system should also have characteristics like:  Complete -        Full functionality -        Rich end user access Open -        Any data source -        Any business application -        Any technology stack  Integrated -        Common metadata -        Common security -        Common system management From a capabilities perspective the system should provide the following capabilities: Define -        Strategy -        Objectives -        Ownership -        KPI's Communicate -        Pervasive -        Collaborative -        Role based -        Secure Execute -        Integrated -        Intuitive -        Secure -        Ubiquitous Monitor -        Multiple styles and formats -        Exception based -        Push & Pull Having talked about the business problem and outlined the blueprint for a technology solution, let's talk about how Oracle Business Intelligence 11g can help. Oracle Business Intelligence is a comprehensive business intelligence solution for reporting, ad hoc query and analysis, OLAP, dashboards and scorecards. Oracle's best in class BI platform is based on an architecturally integrated technology foundation that provides a unified end user experience and features a Common Enterprise Information Model, with common security, query request generation and optimization, and system management.
