  • IValidatableObject vs Single Responsibility

    - by Boris Yankov
    I like the extnesibility point of MVC, allowing view models to implement IValidatableObject, and add custom validation. I try to keep my Controllers lean, having this code be the only validation logic: if (!ModelState.IsValid) return View(loginViewModel); For example a login view model implements IValidatableObject, gets ILoginValidator object via constructor injection: public interface ILoginValidator { bool UserExists(string email); bool IsLoginValid(string userName, string password); } It seems that Ninject, injecting instances in view models isn't really a common practice, may be even an anti-pattern? Is this a good approach? Is there a better one?

  • Azure Mobile Services: available modules

    - by svdoever
    Azure Mobile Services has documented a set of objects available in your Azure Mobile Services server side scripts at their documentation page Mobile Services server script reference. Although the documented list is a nice list of objects for the common things you want to do, it will be sooner than later that you will look for more functionality to be included in your script, especially with the new provided feature that you can now create your custom API’s. If you use GIT it is now possible to add any NPM module (node package manager module, say the NuGet of the node world), but why include a module if it is already available out of the box. And you can only use GIT with Azure Mobile Services if you are an administrator on your Azure Mobile Service, not if you are a co-administrator (will be solved in the future). Until now I did some trial and error experimentation to test if a certain module was available. This is easiest to do as follows:   Create a custom API, for example named experiment. In this API use the following code: exports.get = function (request, response) { var module = "nonexistingmodule"; var m = require(module); response.send(200, "Module '%s' found.", module); }; You can now test your service with the following request in your browser: https://yourservice.azure-mobile.net/api/experiment If you get the result: {"code":500,"error":"Error: Internal Server Error"} you know that the module does not exist. In your logs you will find the following error: Error in script '/api/experiment.json'. Error: Cannot find module 'nonexistingmodule' [external code] atC:\DWASFiles\Sites\yourservice\VirtualDirectory0\site\wwwroot\App_Data\config\scripts\api\experiment.js:3:13[external code] If you require an existing (undocumented) module like the OAuth module in the following code, you will get success as a result: exports.get = function (request, response) { var module = "oauth"; var m = require(module); response.send(200, "Module '" + module + "' found."); }; If we look at the standard node.js documentation we see an extensive list of modules that can be used from your code. If we look at the list of files available in the Azure Mobile Services platform as documented in the blog post Azure Mobile Services: what files does it consist of? we see a folder node_modules with many more modules are used to build the Azure Mobile Services functionality on, but that can also be utilized from your server side node script code: apn - An interface to the Apple Push Notification service for Node.js. dpush - Send push notifications to Android devices using GCM. mpns - A Node.js interface to the Microsoft Push Notification Service (MPNS) for Windows Phone. wns - Send push notifications to Windows 8 devices using WNS. pusher - Node library for the Pusher server API (see also: http://pusher.com/) azure - Windows Azure Client Library for node. express - Sinatra inspired web development framework. oauth - Library for interacting with OAuth 1.0, 1.0A, 2 and Echo. Provides simplified client access and allows for construction of more complex apis and OAuth providers. request - Simplified HTTP request client. sax - An evented streaming XML parser in JavaScript sendgrid - A NodeJS implementation of the SendGrid Api. sqlserver – In node repository known as msnodesql - Microsoft Driver for Node.js for SQL Server. tripwire - Break out from scripts blocking node.js event loop. underscore - JavaScript's functional programming helper library. underscore.string - String manipulation extensions for Underscore.js javascript library. xml2js - Simple XML to JavaScript object converter. xmlbuilder - An XML builder for node.js. As stated before, many of these modules are used to provide the functionality of Azure Mobile Services platform, and in general should not be used directly. On the other hand, I needed OAuth badly to authenticate to the new v1.1 services of Twitter, and was very happy that a require('oauth') and a few lines of code did the job. Based on the above modules and a lot of code in the other javascript files in the Azure Mobile Services platform a set of global objects is provided that can be used from your server side node.js script code. In future blog posts I will go into more details with respect to how this code is built-up, all starting at the node.js express entry point app.js.

  • Xubuntu 12.04: How to get Emacs keybindings?

    - by Marius Hofert
    I work with Xubuntu 12.04 on a MacBook Air. There are various posts about how to use Emacs' keybindings under gnome (see, for example, Enabling Emacs Keybind on Google Chrome, reverting from emacs keybindings in chrome, or http://www.fettesps.com/ubuntu-emacs-keybindings/). I installed gconf-editor and replaced "Greybird" by "Emacs" in desktop - gnome - interface - gtk_theme. This change did not seem to have an effect, though. How can I get Emacs keybindings under Xubuntu? [C-s for "search" and C-y for "paste" in google chrome, for example]

  • Commit Review Questions

    - by Wes McClure
    Note: in this article when I refer to a commit, I mean the commit you plan to share with the rest of the team, if you have local commits that you plan to amend/combine, I am referring to the final result. In time you will find these easier to do as you develop, however, all of these are valuable before checking in!  The pre commit review is a nice time to polish what might have been several hours of intense work, during which these things were the last things on your mind!  If you are concerned about losing your work in the process of responding to these questions, first do a check-in and amend it as you go (assuming you are using a tool such as git that supports this), rolling the result into one nice commit for everyone else.  Did you review your commit, change by change, with a diff utility? If not, this is a list of reasons why you might want to start! Did you test your changes? If the test is valuable to be automated, is it? If it’s a manual testing scenario, did you at least try the basics manually? Are the additions/changes formatted consistently with the rest of the project? Lots of automated tools can help here, don’t try to manually format the code, that’s a waste of time and as a human you will fail repeatedly. Are these consistent: tabs versus spaces, indentation, spacing, braces, line breaks, etc Resharper is a great example of a tool that can automate this for you (.net) Are naming conventions respected? Did you accidently use abbreviations, unless you have a good reason to use them? Does capitalization match the conventions in the project/language? Are files partitioned? Sometimes we add new code in existing files in a pinch, it’s a good idea to split these out if they don’t belong ie: are new classes defined in new files, if this is something your project values? Is there commented out code? If you are removing an existing feature, get rid of it, that is why we have VCS If it’s not done yet, then why are you checking it in? Perhaps a stash commit (git)? Did you leave debug or unnecessary changes? Do you understand all of the changes? http://geekswithblogs.net/wesm/archive/2012/04/11/programming-doesnrsquot-have-to-be-magic.aspx Are there spelling mistakes? Including your commit message! Is your commit message concise? Is there follow up work? Are there tasks you didn’t write down that you need to follow up with? Are readability or reorganization changes needed? This might be amended into the final commit, or it might be future work that needs added to the backlog. Are there other things your team values that you should review?

  • Adding custom interfaces to your mock instance.

    Previously, i made a post  showing how you can leverage the dependent interfaces that is implemented by JustMock during the creation of mock instance. It could be a informative post that let you understand how JustMock behaves internally for classes or interfaces implement other interfaces into it. But the question remains, how you can add your own custom interface to your target mock. In this post, i am going to show you just that. Today, i will not start with a dummy class as usual rather...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Upgrading SSIS Custom Components for SQL Server 2012

    Having finally got around to upgrading my custom components to SQL Server 2012, I thought I’d share some notes on the process. One of the goals was minimal duplication, so the same code files are used to build the 2008 and 2012 components, I just have a separate project file. The high level steps are listed below, followed by some more details. Create a 2012 copy of the project file Upgrade project, just open the new project file is VS2010 Change target framework to .NET 4.0 Set conditional compilation symbol for DENALI Change any conditional code, including assembly version and UI type name Edit project file to change referenced assemblies for 2012 Change target framework to .NET 4.0 Open the project properties. On the Applications page, change the Target framework to .NET Framework 4. Set conditional compilation symbol for DENALI Re-open the project properties. On the Build tab, first change the Configuration to All Configurations, then set a Conditional compilation symbol of DENALI. Change any conditional code, including assembly version and UI type name The value doesn’t have to be DENALI, it can actually be anything you like, that is just what I use. It is how I control sections of code that vary between versions. There were several API changes between 2005 and 2008, as well as interface name changes. Whilst we don’t have the same issues between 2008 and 2012, I still have some sections of code that do change such as the assembly attributes. #if DENALI [assembly: AssemblyDescription("Data Generator Source for SQL Server Integration Services 2012")] [assembly: AssemblyCopyright("Copyright © 2012 Konesans Ltd")] [assembly: AssemblyVersion("3.0.0.0")] #else [assembly: AssemblyDescription("Data Generator Source for SQL Server Integration Services 2008")] [assembly: AssemblyCopyright("Copyright © 2008 Konesans Ltd")] [assembly: AssemblyVersion("2.0.0.0")] #endif The Visual Studio editor automatically formats the code based on the current compilation symbols, hence in this case the 2008 code is grey to indicate it is disabled. As you can see in the previous example I have distinct assembly version attributes, ensuring I can run both 2008 and 2012 versions of my component side by side. For custom components with a user interface, be sure to update the UITypeName property of the DtsTask or DtsPipelineComponent attributes. As above I use the conditional compilation symbol to control the code. #if DENALI [DtsTask ( DisplayName = "File Watcher Task", Description = "File Watcher Task", IconResource = "Konesans.Dts.Tasks.FileWatcherTask.FileWatcherTask.ico", UITypeName = "Konesans.Dts.Tasks.FileWatcherTask.FileWatcherTaskUI,Konesans.Dts.Tasks.FileWatcherTask,Version=3.0.0.0,Culture=Neutral,PublicKeyToken=b2ab4a111192992b", TaskContact = "File Watcher Task; Konesans Ltd; Copyright © 2012 Konesans Ltd; http://www.konesans.com" )] #else [DtsTask ( DisplayName = "File Watcher Task", Description = "File Watcher Task", IconResource = "Konesans.Dts.Tasks.FileWatcherTask.FileWatcherTask.ico", UITypeName = "Konesans.Dts.Tasks.FileWatcherTask.FileWatcherTaskUI,Konesans.Dts.Tasks.FileWatcherTask,Version=2.0.0.0,Culture=Neutral,PublicKeyToken=b2ab4a111192992b", TaskContact = "File Watcher Task; Konesans Ltd; Copyright © 2004-2008 Konesans Ltd; http://www.konesans.com" )] #endif public sealed class FileWatcherTask: Task, IDTSComponentPersist, IDTSBreakpointSite, IDTSSuspend { // .. code goes on... } Shown below is another example I found that needed changing. I borrow one of the MS editors, and use it against a custom property, but need to ensure I reference the correct version of the MS controls assembly. This section of code is actually shared between the 2005, 2008 and 2012 versions of my component hence it has test for both DENALI and KATMAI symbols. #if DENALI const string multiLineUI = "Microsoft.DataTransformationServices.Controls.ModalMultilineStringEditor, Microsoft.DataTransformationServices.Controls, Version=11.0.00.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"; #elif KATMAI const string multiLineUI = "Microsoft.DataTransformationServices.Controls.ModalMultilineStringEditor, Microsoft.DataTransformationServices.Controls, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"; #else const string multiLineUI = "Microsoft.DataTransformationServices.Controls.ModalMultilineStringEditor, Microsoft.DataTransformationServices.Controls, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"; #endif // Create Match Expression parameter IDTSCustomPropertyCollection100 propertyCollection = outputColumn.CustomPropertyCollection; IDTSCustomProperty100 property = propertyCollection.New(); property = propertyCollection.New(); property.Name = MatchParams.Name; property.Description = MatchParams.Description; property.TypeConverter = typeof(MultilineStringConverter).AssemblyQualifiedName; property.UITypeEditor = multiLineUI; property.Value = MatchParams.DefaultValue; Edit project file to change referenced assemblies for 2012 We now need to edit the project file itself. Open the MyComponente2012.cproj  in you favourite text editor, and then perform a couple of find and replaces as listed below: Find Replace Comment Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91 Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91 Change the assembly references version from SQL Server 2008 to SQL Server 2012. Microsoft SQL Server\100\ Microsoft SQL Server\110\ Change any assembly reference hint path locations from from SQL Server 2008 to SQL Server 2012. If you use any Build Events during development, such as copying the component assembly to the DTS folder, or calling GACUTIL to install it into the GAC, you can also change these now. An example of my new post-build event for a pipeline component is shown below, which uses the .NET 4.0 path for GACUTIL. It also uses the 110 folder location, instead of 100 for SQL Server 2008, but that was covered the the previous find and replace. "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\NETFX 4.0 Tools\gacutil.exe" /if "$(TargetPath)" copy "$(TargetPath)" "%ProgramFiles%\Microsoft SQL Server\110\DTS\PipelineComponents" /Y

  • Web application framework for embedded systems?

    - by datenwolf
    I'm currently developing the software for a measurement and control system. In addition to the usual SCPI interface I'd also give it a nice HTTP frontend. Now I don't want to reinvent the wheel all over again. I already have a simple HTTPD running, but I don't want to implement all the other stuff. So what I'm looking for is a web application toolkit targeted at embedded system development. In particular this has to run on a ARM Cortex-M4, and I have some 8k of RAM available for this. It must be written in C. Is there such a thing or do I have to implement this myself?

  • Overload Avoidance

    - by mikef
    A little under a year ago, Matt Simmons wrote a rather reflective article about his terrifying brush with stress-induced ill health. SysAdmins and DBAs have always been prime victims of work-related stress, but I wonder if that predilection is perhaps getting worse, despite the best efforts of Matt and his trusty side-kick, HR. The constant pressure from share-holders and CFOs to 'streamline' the workforce is partially to blame, but the more recent culprit is technology itself. I can't deny that the rise of technologies like virtualization, PowerCLI, PowerShell, and a host of others has been a tremendous boon. As a result, individual IT professionals are now able to handle more and more tasks and manage increasingly large and complex environments. But, without a doubt, this is a two-edged sword; The reward for competence is invariably more work. Unfortunately, SysAdmins play such a pivotal role in modern business that it's easy to see how they can very quickly become swamped in conflicting demands coming from different directions. However, that doesn't justify the ridiculous hours many are asked (or volunteer) to devote to their work. Admirably though their commitment is, it isn't healthy for them, it sets a dangerous expectation, and eventually something will snap. There are times when everyone needs to step up to the plate outside of 'normal' work hours, but that time isn't all the time. Naturally, with all that lovely technology, you can automate more and more of those tricky tasks to keep on top of the workload, but you are still only human. Clever though you may be, there is a very real limit to how far technology can take you. I'm not suggesting that you avoid these technologies, or deliberately aim for mediocrity; I'm just saying that you need to be more than just technically skilled (and Wesley Nonapeptide riffs on and around this topic in his excellent 'Telepathic Robot Drones' blog post). You need to be able to manage expectations, not just Exchange. Specifically, that means your own expectations of what you are capable of, because those come before everyone else's. After all, how can you keep your work-life balance under control, if you're the one setting the bar way too high? Talking to your manager, or discussing issues with your users, is only going to be productive if you have some facts to work with. "Know Thyself" is the first law of managing work overload, and this is obviously a skill which people develop over time; the fact that veteran Sysadmins exist at all is testament to this. I'd just love to know how you get to that point. Personally, I'm using RescueTime to keep myself honest, but I'm open to recommendations for better methods. Do you track your own time, do you have an intuitive sense of what is possible, or do you just rely on someone else to handle that all for you? Cheers, Michael

  • Is there any practical use for the empty type in Common Lisp?

    - by Pedro Rodrigues
    The Common Lisp spec states that nil is the name of the empty type, but I've never found any situation in Common Lisp where I felt like the empty type was useful/necessary. Is it there just for completeness sake (and removing it wouldn't cause any harm to anyone)? Or is there really some practical use for the empty type in Common Lisp? If yes, then I would prefer an answer with code example. For example, in Haskell the empty type can be used when binding foreign data structures, to make sure that no one tries to create values of that type without using the data structure's foreign interface (although in this case, the type is not really empty).

  • Design for a plugin based application

    - by Varun Naik
    I am working on application, details of which I cannot discuss here. We have core framework and the rest is designed as plug in. In the core framework we have a domain object. This domain object is updated by the plugins. I have defined an interface in which I have function as DomainObject doProcessing(DomainObject object) My intention here is I pass the domain object, the plug in will update it and return it. This updated object is then passed again to different plugin to be updated. I am not sure if this is a good approach. I don't like passing the DomainObject to plugin. Is there a better way I can achieve this? Should I just request data from plugin and update the domain object myself?

  • How to install Pear Linux's shell in Ubuntu?

    - by Emerson Hsieh
    For people who doesn't know what Pear Linux is: Pear Linux is a French Ubuntu-based desktop Linux distribution. Some of its features include ease-of-use, custom user interface with a Mac OS X-style dockbar, and out-of-the-box support for many popular multimedia codecs. Excerpt from Distrowatch. When this Linux Distribution came out, I immediately went to the website and found out that Pear Linux is actually Mac OSX with a pear. I was going to download it and install Pear Linux as a triple-boot on my computer (Windows and Ubuntu installed). Then I remembered that Pear Linux is Ubuntu based. So I thought of a better Idea of installing only the Comice OS Shell in Ubuntu(the Desktop environment of Pear Linux), so that I can select that in the login screen. Is that possible? EDIt: Found this.

  • Elastic PaaS with WebLogic and OpenStack, part I

    - by Jernej Kaše
    In my previous blog I described the steps to get OpenStack on Solaris up and running. Now we'll explore how WebLogic and OpenStack can work together to deliver truly elastic Middleware Platform as a Service. Middleware / Platform as a Service goals First, let's define what PaaS should be : PaaS offerings facilitate the deployment of applications without the complexity of managing the underlying hardware and software and provisioning hosting capabilities. To break it down: - PaaS provides a complete platform for hosting solutions (Java EE, SOA, BPM, ...) - Infrastructure provisioning (virtual machine, OS, platform) and managing is hidden from the PaaS user [administrator or developer] - Additionally, PaaS could / should define target SLAs, and the platform should ensure the SLAs are meet automatically. PaaS use case To make it more tangible, we have an IT Administrator who has the requirement to deploy a Java EE enterprise application. The application is used by external users who need to submit reports by the end of each month. As a result, the number of concurrent users will fluctuate, with expected huge spikes around the end of each month. The SLA agreed by the management is that no more than 100 requests should be waiting to be processes at any given time. In addition, the IT admin has no more than 3 days to have the platform and the application operational. The Challenges Some of the challenges the IT Administrator is facing are: - how are we going to ensure the processing power? - how are we going to provision the (virtual) machines, Java EE platform and deploy the application? - how are we going to monitor the SLA? - how are we going to react to SLA, and increase capacity?  The Ideal Solution Ideally, the whole process should be automated, "set it and forget" and require no human interaction: - The vendor packages the solution as deployable image(s) - The images are deployed to the IaaS - From there, automated processes take care of SLA  Solution Architecture with WebLogic 12c, Dynamic Clusters, OpenStack & Solaris OracleSolaris provides OS and virtualisation through Solaris Zones OpenStack is a part of Solaris 11.2 and provides Cloud Management (console and API) WebLogic 12c with Dynamic Clusters provides the Platform Trafic Manager provides load balancing On top of out that, we are going to implement a small control script - Cloud Manager - which is going to monitor SLA through WebLogic Diagnostic Framework. In case there are more than 100 pending requests, the script will: - provision a new virtual machine based on image which is configured for the WebLogic domain - add the machine to WebLogic domain - Increase the number of servers in dynamic cluster - Start the newly provisioned server  Stay tuned for part II The hole solution with working demo will be presented in one of our Partner WebCasts in June, exact date TBA. Jernej Kaše is a Fusion Middleware Specialist working closely with Oracle Partners in the ECEMEA region to grow their business by leveraging Oracle technology.

  • Getting bank account information from a bank and displaying on a website [closed]

    - by Ali Syed
    Hello I am looking for a way to get bank account information (transactions and balance) from a financial institution and display it on a website. The question is vague intentionally.... Everything is open. I haven't chosen a bank, serverside technology or front end technology. The idea is to have a script run automatically periodically (once or twice a day) and get the latest account information from the bank server automatically. Probably something in the direction of OFX (Open financial exchange), HBCI (home banking c.. interface), fnts or something like it. Even working over a closed source API is not out of question: Wesabe or Mint or something. Paypal is not an option because it won't work in India or Pakistan. cheers *Explanation: I have an exclusive small club. My members make irregular payments. These transactions should be online for all MEMBERS (with login) to see *

  • Python C API return more than one value / object

    - by Grisu
    I got the following problem. I have written a C-Extension to Python to interface a self written software library. Unfortunately I need to return two values from the C function where the last one is optional. In Python the equivalent is def func(x,y): return x+y, x-y test = func(13,4) #only the first value is used In my C extension I use return Py_BuildValue("ii",x+y,x-y); which results in a tuple. If I now try to access the return value from Python via test2 = cfunc(13,4) print(test2) I got a tuple instead of only the first return value. How is possible to build the same behavior as in Python from C Extension?

  • Email sent via Google via relayhost being marked as spam

    - by Mark H
    Company email hosted by Google Apps. Company PBX in-house is Elastix. All voicemails received on the extensions of Elastix are supposed to be emailed by the CentOS server (Postfix) to the email address of the employee. Using relayhost on postfix, I am sending those emails through Google Apps (smtp.gmail.com), but some of these voicemail emails end up in the spam. Sending it through Google, and sending it to an email hosted by Google - yet there's spam. Email sent from the Google Apps interface - no complaints of it going to spam - just from the Elastix server. I've just asked our DNS domain guys to add spf records, but is that all that's needed?

  • Performance required to improve Windows Experience Index?

    - by Ian Boyd
    Is there a guide on the metrics required to obtain a certain Windows Experience Index? A Microsoft guy said in January 2009: On the matter of transparency, it is indeed our plan to disclose in great detail how the scores are calculated, what the tests attempt to measure, why, and how they map to realistic scenarios and usage patterns. Has that amount of transparency happened? Is there a technet article somewhere? If my score was limited by my Memory subscore of 5.9. A nieve person would suggest: Buy a faster RAM Which is wrong of course. From the Windows help: If your computer has a 64-bit central processing unit (CPU) and 4 gigabytes (GB) or less random access memory (RAM), then the Memory (RAM) subscore for your computer will have a maximum of 5.9. You can buy the fastest, overclocked, liquid-cooled, DDR5 RAM on the planet; you'll still have a maximum Memory subscore of 5.9. So in general the knee-jerk advice "buy better stuff" is not helpful.

The information i've been able to compile so far, chiefly from 3 Windows blog entries, and an article: Memory subscore Score Conditions ======= ================================ 1.0 < 256 MB 2.0 < 500 MB 2.9 <= 512 MB 3.5 < 704 MB 3.9 < 944 MB 4.5 <= 1.5 GB 5.9 < 4.0GB-64MB on a 64-bit OS Windows Vista highest score 7.9 Windows 7 highest score Graphics Subscore Score Conditions ======= ====================== 1.0 doesn't support DX9 1.9 doesn't support WDDM 4.9 does not support Pixel Shader 3.0 5.9 doesn't support DX10 or WDDM1.1 Windows Vista highest score 7.9 Windows 7 highest score Gaming graphics subscore Score Result ======= ============================= 1.0 doesn't support D3D 2.0 supports D3D9, DX9 and WDDM 5.9 doesn't support DX10 or WDDM1.1 Windows Vista highest score 6.0-6.9 good framerates (e.g. 40-50fps) at normal resoltuions (e.g. 1280x1024) 7.0-7.9 even higher framerates at even higher resolutions 7.9 Windows 7 highest score Processor subscore Score Conditions ======= ========================================================================== 5.9 Windows Vista highest score 6.0-6.9 many quad core processors will be able to score in the high 6 low 7 ranges 7.0+ many quad core processors will be able to score in the high 6 low 7 ranges 7.9 8-core systems will be able to approach 8.9 Windows 7 highest score Primary hard disk subscore (note) Score Conditions ======= ======================================== 1.9 Limit for pathological drives that stop responding when pending writes 2.0 Limit for pathological drives that stop responding when pending writes 2.9 Limit for pathological drives that stop responding when pending writes 3.0 Limit for pathological drives that stop responding when pending writes 5.9 highest you're likely to see without SSD Windows Vista highest score 7.9 Windows 7 highest score Bonus Chatter You can find your WEI detailed test results in: C:\Windows\Performance\WinSAT\DataStore e.g. 2011-11-06 01.00.19.482 Disk.Assessment (Recent).WinSAT.xml <WinSAT> <WinSPR> <DiskScore>5.9</DiskScore> </WinSPR> <Metrics> <DiskMetrics> <AvgThroughput units="MB/s" score="6.4" ioSize="65536" kind="Sequential Read">89.95188</AvgThroughput> <AvgThroughput units="MB/s" score="4.0" ioSize="16384" kind="Random Read">1.58000</AvgThroughput> <Responsiveness Reason="UnableToAssess" Kind="Cap">TRUE</Responsiveness> </DiskMetrics> </Metrics> </WinSAT> Pre-emptive snarky comment: "WEI is useless, it has no relation to reality" Fine, how do i increase my hard-drive's random I/O throughput?

  • Wireless internet connection connects but internet does not work (no packets received). Wired does.

    - by Rodney
    When I connect my PC via ethernet cable to my ADSL router it works fine. When I connect via Wireless it connects and the internet will work for a random amount of time and then stop working. It stays connected with a strong signal but no packets are received. My laptop/iphone are right next to it and wireless works fine. If I open the Wireless USB status, it says it is connected to my SSID with full strength (54 mps - I am 3 meteres away from my router) and the activty shows as Packets 594 SENT and 105 RECEIVED (this goes up VERY slowly) I have tried the following: Turned off anitvirus and firewall completely. Tested the wifi signal- I am writing this on my laptop which is next to my PC and also has full wifi strength. Tried a different wireless adapter - I dug out an old PCI wireless card - it does the exact same thing. Compared all wireless settings to my laptop. I can ping google.com and it replies (sometimes with packet loss) When I reboot the PC it will connect for a minute or two (random time) and then just stops again. I tried Firefox, IE etc. no joy I have updated all latest versions (Netgear WG111v2) and drivers Checked Event Log - nothing unusual Ping the router (and even connect as admin for the few minutes when the internet does work) Changed the MTU down to 1200 using DrTCP Checked Device Manager for conflicts - none. I ping the router from the PC (192.168.0.10 - 192.168.0.1) and it replies with 4 packets. BUT, on my router admin page (which I access via http on my laptop wirelessly) - if I ping 192.168.0.10 all packets timeout (pinging my laptop 192.168.0.12 works fine) My router admin page shows the leased IP address for 192.168.0.10 (ie it is definitely talking to the router initially) Now I am out of ideas - please help. I think it is an OS/Software issue as I have tried 2 different wireless adapaters (PCI and USB) with the same result but all other wireless devices work fine around mine). It's not the firewall. It is getting assigned an IP address correctly (my PC gets 192.168.0.10, my laptop is .12) It is assigned by DHCP. As soon as I plug in the ethernet cable it all works fine. Repairing the adapter sometimes helps but it will always stop working after a random time. The wireless adapter always shows as connected with Excellent signal but the internet does not work. I am running Windows XP SP3 and have tried a Netgear WG111v2 USB adapter. Thanks in advance! UPDATE: The internet seems to be working, it is just either sending packets too small or slow to work (some small pages load bits of them very slowly but then hang). XP seems to have a networking diagnostic app - here is the output: Last diagnostic run time: 08/30/10 08:16:38 IP Configuration Diagnostic Invalid IP address info Valid IP address detected: 192.168.0.10 IP Layer Diagnostic Corrupted IP routing table info The default route is valid info The loopback route is valid info The local host route is valid info The local subnet route is valid Invalid ARP cache entries action The ARP cache has been flushed Gateway Diagnostic Gateway info The following proxy configuration is being used by IE: Automatically Detect Settings:Disabled Automatic Configuration Script: Proxy Server: Proxy Bypass list: info This computer has the following default gateway entry(ies): 192.168.0.1 info This computer has the following IP address(es): 192.168.0.10 info The default gateway is in the same subnet as this computer info The default gateway entry is a valid unicast address info The default gateway address was resolved via ARP in 1 try(ies) info The default gateway was reached via ICMP Ping in 1 try(ies) info TCP port 80 on host 65.55.12.249 was successfully reached info The Internet host www.microsoft.com was successfully reached info The default gateway is OK DNS Client Diagnostic DNS - Not a home user scenario info Using Web Proxy: no info Resolving name ok for (www.microsoft.com): yes No DNS servers DNS failure HTTP, HTTPS, FTP Diagnostic HTTP, HTTPS, FTP connectivity info FTP (Passive): Successfully connected to ftp.microsoft.com. info HTTP: Successfully connected to www.microsoft.com. warn HTTPS: Error 12002 connecting to www.microsoft.com: The operation timed out warn HTTPS: Error 12002 connecting to www.passport.net: The operation timed out error Could not make an HTTPS connection. info Redirecting user to support call WinSock Diagnostic WinSock status info All base service provider entries are present in the Winsock catalog. info The Winsock Service provider chains are valid. info Provider entry MSAFD Tcpip [TCP/IP] passed the loopback communication test. info Provider entry MSAFD Tcpip [UDP/IP] passed the loopback communication test. info Provider entry RSVP UDP Service Provider passed the loopback communication test. info Provider entry RSVP TCP Service Provider passed the loopback communication test. info Connectivity is valid for all Winsock service providers.

  • Ubuntu 12.10 Unity and Gnome not showing correctly after log in

    - by Luis Rodriguez
    Hello Ubuntu community. Since last Saturday when I was about to log into my ubuntu session as always using Unity interface, I came across with something that never happened to me before. When I logged in, the screen only showed the Desktop wallpaper but neither the bar from the top screen neither the dash bar from the left side appear, and after a few minutes of being logged in, I found myself being spammed with Ubuntu errors windows, over and over again. I logged out using ctrl+alt+del and tried my Gnome sessio. But I got exactly the same problem. I'm only able to use Gnome Classic and Classic (No Effects) Can anybody help? Hope a reply soon, and thanks in advance.

  • How do I overcome paralysis by analysis when coding?

    - by LuxuryMode
    When I start a new project, I often times immediately start thinking about the details of implementation. "Where am I gonna put the DataBaseHandler? How should I use it? Should classes that want to use it extend from some Abstract superclass..? Should I an interface? What level of abstraction am I going to use in my class that contains methods for sending requests and parsing data?" I end up stalling for a long time because I want to code for extensibility and reusability. But I feel it almost impossible to get past thinking about how to implement perfectly. And then, if I try to just say "screw it, just get it done!", I hit a brick wall pretty quickly because my code isn't organized, I mixed levels of abstractions, etc. What are some techniques/methods you have for launching into a new project while also setting up a logical/modular structure that will scale well?

  • Versioning Strategy for Service Interfaces JAR

    - by Colin Morelli
    I'm building a service oriented architecture composed (mostly) of Java-based services, each of which is a Maven project (in an individual repository) with two submodules: common, and server. The common module contains the service's interfaces that clients can include in their project to make service calls. The server submodule contains the code that actually powers the service. I'm now trying to figure out an appropriate versioning strategy for the interfaces, such that each interface change results in a new common jar, but changes to the server (so long as they don't impact the contract of the interfaces) receive the same common jar. I know this is pretty simple to do manually (simply increment the server version and don't touch the common one), but this project will be built and deployed by a CI server, and I'd like to come up with a strategy for automatically versioning these. The only thing I have been able to come up with so far is to have the CI server md5 the service interfaces.

  • Python C API return more than one value / object without building a tuple [migrated]

    - by Grisu
    I got the following problem. I have written a C-Extension to Python(2.7 / 3.2) to interface a self written software library. Unfortunately I need to return two values from the function where the last one is optional. In Python I tried def func(x,y): return x+y, x-y test = func(13,4) but test is a tuple. If I write test1,test2 = func(13,4) I got both values separated. Is there a possibility to return only one value without unpacking the tuple, i.e. the second(,.. third, ..fourth) value gets neglected? And if such a solution existst, how does it look for the C-API? Because return Py_BuildValue("ii",x+y,x-y); results in a tuple as well.

  • Reducing brightness of large areas containing bright colours

    - by intuited
    I do most of my work in either a terminal or a web browser. I prefer my terminals to use bright colours on dark. I would really prefer that web pages tended to look this way as well, but that's not under my control. The problem is that when I switch from a light-on-dark terminal to a dark-on-light web page (like this one), my eyes have to adjust to the overall rise in screen brightness. Apparently this is bad for your eyes, in addition to being painful and annoying. It would seem to be possible for some layer of the interface to adjust the displayed colours for parts of the screen, or perhaps for particular windows, to reduce the brightness of the brighter areas of the screen. Can this be done, possibly with a Compiz extension?
