• Git dont sync files untill committed even if checkout different branch

  - by DertWaiter

  Ok i have git 1.7.11.1 on windows and i have local test reposotory with 2 branches one is master with index.php help.php then i create another branch called slave :) I run from git bash rm help.php and it dissapears from the folder, but i dont stage anything. I switch to checkout master branch and it supposed to restore file help.php because its not modified in master branch isnt it? And it does not do it. When i back to slave branch and commit and then switch to checkout master then help.php appears. is that the way it supposed to be why?

• How to get some experience in a new programming language? [closed]

  - by BeCool

  I have commercial experience in one programming language but I want to make a switch to another programming language (C#/.NET). I am in full-time employment so whenever I get free time I read relevant books or use online resources available. My questions are - How do I develop experience in the new language of interest (without leaving current job)? The best way I find to learn is to develop a project - How do you / Where can you find new test projects which you can refer to in the interview (these don't have to be real projects but perhaps I can take the code with me in a usb stick as proof). Do you have any tips/advice for me regarding best way to switch career? My lanugauge of choice is C# - so c# related answers will be appreciated.

• Should I go with Android or Try Windows Phone 7?

  - by Omnion

  I already know C# and am familiar with XNA. So it would make sense to develop for the Windows Phone 7, but would it be worth while to learn Java, get familiar with Android, and instead develop for Android devices? Android has been around longer so it would probably have a larger user base. Is it really worth it to try to develop for one of the more popular mobile platforms. (Windows Phone 7 has been out for like a month?) I haven't tried either one yet though. I'm also going to buy a phone, so this decision would probably influence the phone that I buy. (to develop/test on)

I want to totally remove my 12.04 and do a clean install of 12.10, i created a live USB then i restarted my computer to boot from USB, i got the following error: Product is covered by one or more of the following patents: US5,434,872, US5,732,894, (and many more) Under that i see: PCIe GBE Family Controller Series v2.38 Media test failiure Exiting PXE ROM And then it reboots I've searched a lot for an answer, i guess the problem is with something in my bios, but i didn't find a fix.

• What causes Google Analytics tags to work on some machines but not on others?

  - by Dallas

  The title of this question says it all. I am trying to update my code from the deprecated _getTracker() method to _createTracker(), but am experiencing inconsistent results. I have tried traditional and Asynch methods using a JSP include, but they all have the same result. My pageviews, and others in the office all show up in analytics. I have tried various test cases, but their visits are just not registering at all for them, but are showing up for me. The client has tried on multiple machines, and I have walked through with them step by step, so I know it's not just user error. I know that javascript being turned off will cause the tags not to work, but I am wondering if what else might cause the tags to not be recognized. I would appreciate any and all ideas.

• jQuery Mobile Frame Forwarding [on hold]

  - by Nizam

  I have a site that does a standard forward to another site [301 Redirect]. In the redirected site, I detect if the device is a mobile using the following code: if (/Android|webOS|iPhone|iPad|iPod|BlackBerry/i.test(navigator.userAgent)) { window.location.replace("Mobile/Login/Login.aspx") } else { window.location.replace("Apps/Login/Login.aspx") } It works and jQuery mobile makes the site fits device very well. To do so, I use the following code in ASPX page: <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1" /> The problem is that I am wanting to frame forward - instead of standard forward - (there are a lot of advantages), but the site is not fitted for the device anymore, and even the icon I have chosen for my page is not well defined anymore. The code I use to set the icon of page is: <link rel="apple-touch-icon" href="../../Apps/Imagens/Icone.png" /> My site is hosted by Mochahost My question is: Is there anything I could do to make it works?

• Popper Email Notifier not working

  - by Joel

  Using Maverick 64bit I downloaded Popper Email Notifier today. Installed it from the v023 deb. https://launchpad.net/popper I configured it, and the TEST tab shows I configured everything properly. I can't get Popper to appear in the notification menu. I have restarted gnome-pannel, restarted my computer, reinstalled the app. No luck. I checked the /usr/share/indicators/messages/applications/ folder, and there's only the defaults there. Anyone know how to fix this? Even if someone knows what file I can drop into that folder to make it work that'd be great. Edit: I wonder if it's because I removed the evolution-indicator package? Thanks!

  Upgrading to Ubuntu 14.04 (and Apache2 2.4) server I can't use MySQL as htaccess; Before upgrading I was using MySQL as htaccess in the virtual host - worked nicely: <Directory /var/www/html/tilmelding/login> AuthBasicAuthoritative Off AuthUserFile /dev/null # begin auth_mysql configuration AuthMySQL On AuthMySQL_Host localhost AuthMySQL_User ********** AuthMySQL_Password ********* AuthMySQL_DB ********** AuthMySQL_Password_Table user_info AuthMySQL_Username_Field user_name AuthMySQL_Password_Field user_passwd AuthMySQL_Empty_Passwords Off AuthMySQL_Encryption_Types PHP_MD5 AuthMySQL_Authoritative AuthType Basic AuthName "auth_mysql test" Require valid-user After upgrade it didn’t work.

• Is there any simple C++ code to grab video from UVC webcam and display it simultaneously?

  - by mShero

  I'm very very new to Linux and programming! I'm using ubuntu 11.10 - 64 bits with gcc 4.6.1 I've been searching online for an example C++ code that simply grabs video from a compliant UVC webcam and displays it simultaneously.. I need to compile it on gcc. In OpenCV, it's a very simple code less than 20 lines as I remember! I found this: http://v4l2spec.bytesex.org/spec/capture-example.html But it's very huge code relative to OpenCV code ?! and even when I tried to compile it using gcc.. I got many errors! I copied the code into a cpp file: cap.cpp then wrote in the terminal: gcc cap.cpp -o cap and the errors showed up... same errors with g++ I hope if someone can help me and tell me where can I find another simpler code? and how can I test it ? Thank you :)

• NUnit vs. MsTest: NUnit wins for Unit Testing.

  People are still wondering what are the differences between the two most popular unit testing frameworks in the .NET world: the open source NUnit and the commercial MsTest). Heres a short list of what i remember instantly: Nunit contains a [TestCase] attribute that allows implementing parametrized tests. this does not exist in msTest MsTest's ExpectedException attribute has a bug where the expected message is never really asserted even if it's wrong - the test will pass. Nunit has an...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.

• Intersection of player and mesh

  - by Will

  I have a 3D scene, and a player that can move about in it. In a time-step the player can move from point A to point B. The player should follow the terrain height but slow going up cliffs and then fall back, or stop when jumping and hitting a wall and so on. In my first prototype I determine the Y at the player's centre's X,Z by intersecting a ray with every triangle in the scene. I am not checking their path, but rather just sampling their end-point for each tick. Despite this being Javascript, it works acceptably performance-wise. However, because I am modeling the player as a single point, the player can position themselves so that they are half-in a cliff face and so on. I need to model them as as a solid e.g. some cluster of spheres or a even their fuller mesh. I am also concerned that if they were moving faster they might miss the test altogether. How should I solve this?

• Would I benefit changing from PHP to Node.js (in context)

  - by danneth

  The situation: We are about to roll out what is essentially a logging service. As we are rather PHP heavy, the current implementation use it. We will have about 200 computers (most on the same network) that will each send, via HTTP POST, around 5000 requests/day. With each request containing about 300 bytes of data. The receiving end is hosted at Amazon and is a very simple PHP form with some simple validation that puts everything in a database. Now, I've recently been introduced to Node.js and I'm curious as to if it would be a good fit for the backend here. Granted I could easily build something to test this. But since I haven't fully grasped the async-methology I would really like someone with experience to explain it to me.

• Support du HTML5 : Opera, Firefox, Maxthon et BlackBerry les plus complets sur mobiles, tablettes et PC d'après un comparatif hollandais

  Support du HTML5 : Opera, Firefox, BlackBerry et Maxthon les plus complets Sur mobiles, tablettes et PC d'après un comparatif hollandais Bien sûr, un seul test ne vaut pas parole d'évangile. Mais celui-ci, vu le nombre de critères qu'il intègre, a tout de même son intérêt. A l'origine, le site HTML5test mesure les performances des navigateurs dans leurs supports du standard Web. Le résultat est présenté sous la forme d'un score, dont le maximum est de 500 points, détaillé ensuite balise par balise et fonctionnalité par fonctionnalité (canvas, vidéo, forms, glisser-déposer, cache, etc.).

• Error Setting Java Environment Variables

  - by Cherie Riesberg

  Problem:  Not exactly SharePoint, but the issue is when setting the %JAVA_HOME% environment variable, Java installs to the Program Files directory by default.  The space in the path seems to stop the variable from being read.  You get an error. Solution:  Change Program Files to Progra~1, so the path now looks like this: C:\Progra~1\Java\jdk1.6.0_23\bin\; You can type %JAVA_HOME%\bin\javac to test.  Output should look like this: Usage: javac <options> <source files> where possible options include: ...

• Good source for interview-style coding problems for entry/intermediate developers?

  - by soster

  I have taught myself to code over the past few years and do not have a computer science degree. As a result, I lack experience from many things, such as the basic homework/test questions many CS graduates take for granted. I recently had a tech screen interview where I fumbled and struggled to finish a (relatively) common question, I believe due to this inexperience. My question to all of you is this: do you know a good source for a bunch of these problems that includes answers, for an entry/intermediate developer who is trying to gain coding problem solving experience? The ones I've been able to find on the internet are for coding teams, so they're a bit too complicated for me. Thanks so much in advance.

• Where can I find a collection of photorealistic scenes? [on hold]

  - by emchristiansen

  Where can I find a collection of 10-100 3D scenes with photorealistic levels of detail? For example, the scene rendered here contains photorealistic detail. Note I want the underlying object models, textures, etc, not final renderings. I'll be using these scenes to test a computer vision idea. BTW, this is a reposting of this question. I wasn't able to find a Stack Exchange site that is perfectly suited to the question, but as this is a modeling and rendering question, I'm hoping it is a good enough match for the venue.

• Disposing of ContentManager increases memory usage

  - by Havsmonstret

  I'm trying to wrap my head around how memory management works in XNA 4.0 I've created a screen management test and when I close a screen, the ContentManager created by that screen is unloaded. I have used ANTS Memory Manager to look at how the memory usage is altered when I do this, and it gives me some results which makes me scratch my head. The game starts with loading two textures (435kB and 48,3kB) which puts the usage at about 61MB. Then, when I delete the screen and runs Unload on the ContentManager, the memory usage drops to 56,5MB but instantly after goes up to 64,8MB. Am I doing something wrong or is this usual for XNA games? Do I have to dispose of everything the ContentManager loads seperatly or do I need to do something more to the ContentManager? Thanks in advance!

• Wireless connectivity Wifi 7260 on Ubuntu 10.04

  - by user292332

  I am trying to install Wireless networking on Dell Latitude E5440 Wifi 7260- Ubuntu 10.04.(Yes I know it is old- see the complication below) I did get the wired connection working but our classrooms are wireless. I have tried to upgrade to version 12 last year but to my horror during the first week of class the nfs mounts did not work for multiple users. I never thought to test for more then one person at at time!! I have not been able to find a fix for the upgrade so I must remain at 10.04. NFS mounts are a must for student home directory access on the servers. All desktops are 10.04 as are the servers. Does anyone have a solution to the wireless problem in version 10.04/ or the nfs mounts solution in version 12. Thank you so much. Val

• Default Location of Web Site Content

  - by RichyL

  I am looking to install mediawiki on a production server (after doing a test on a development one). I could not really understand why the default location for the mediawiki files is /var/lib/mediawiki. I would have thought /var/www would've made more sense. I did some research and in http://people.canonical.com/~cjwatson/ubuntu-policy/policy.html/ch-customized-programs.html#s-web-appl it says the following Web Document Root Web Applications should try to avoid storing files in the Web Document Root. Instead they should use the /usr/share/doc/package directory for documents and register the Web Application via the doc-base package. If access to the web document root is unavoidable then use /var/www Can anyone explain why this is please?

• System.getProperty("user.dir") cannot get my project root path ,but the path which my eclipse is located

  - by facebook-100005613813158

  As the title goes , I have class named GetException.java,inside it ,I read a xml file in a static code block like(Because this document is shared): static{ ... document = db.parse(new File(System.getProperty("user.dir")+"/src/exception/ExceptionCode.xml")); ... } To test if the file path is correct, I write a main function just inside GetException.java, it proves that the path is correct ,xml file can be read successfully. My project root dir is "/home/wuchang/workspace/MongodbI". But When this Class is loaded from other class,such as I called one of its static functions , it reports the error message: /home/mrs/??/eclipse/src/exception/ExceptionCode.xml (No such file or directory) /home/mrs/??/eclipse/ is actually my eclipse installation directory.So , I wander how System.getProperty("user.dir") returned the eclipse installation directory to me ,instead of my project root directory?

• Display on secondary video card (Nvidia 8400 GS): horrible refresh, bogs system

  - by minameismud

  This is my work computer, but it's a small shop. We do business software development. The most hardcore thing we create is some web animations with html5 and fancy javascript/css. The base machine is a Dell Precision T3500 - Xeon W3550 (3.07GHz quad), 6GB ram, pair of 500GB harddrives, and Win 7 x64 Enterprise SP1. My primary video card is an ATI FirePro V4800 1GB in a PCIe slot of some speed driving a pair of 23s at 1920x1080 through DisplayPort-HDMI adapters. The secondary card is an NVidia GeForce 8400GS in a PCI slot driving a single 17" at 1280x1024 through DVI. On either of the 23" monitors, windows move smoothly, scroll quickly, and are generally very responsive. On the 17", it's slow, chunky, and when I'm trying to scroll a ton of content, Windows will occasionally suggest I drop to the Windows Basic theme. I've updated drivers for both cards, and I've gotten every Windows update relating to video. Specifically: ATI FirePro Provider: Advanced Micro Devices, Inc Date: 6/22/2014 Version: 13.352.1014.0 NVidia 8400 GS Provider: NVIDIA Date: 7/2/2014 Version: 9.18.13.4052 Unfortunately, new hardware isn't really an option. Is there anything I can do software-wise to speed up the NVidia-driven monitor?

• Domain resolution - local first then external

  - by stefgosselin

  I would like to know how I can configure my dns settings so that domain is resolved locally first, then if not resolved it goes to external DNS. I had this working before, I am using Ubuntu through a VM and need the local domain to resolve first but since I have upgraded I had to reconfigure network and now it works only external, local host file does not seem to even be used. Is there an easy way to check this out? I did slap it up in google but no specific answer seemed to match my case and I too tight on delivery deadline to test-and-try different approaches. You guys rock, thanks.

• Web Form Testing [closed]

  I created a application for a client that is along the lines of a ticket tracking system. I wanted to know if anyone know of software that could beta test the web forms. Well I am looking for something that could automatically populate/fill whatever forms are on the web page with generic data. The purpose of this is to just randomly populate data and see if I get any errors on the page when submitted plus to also see how validation for the form functions. Does anyone know of anything that could do this?
