• Lost power during upgrade, how do I recover?

  - by Ryan McClure

  I was attempting to update my 11.10 install to 12.04beta. During the install step, I accidentally lost power to my laptop (the power cable came unplugged) and it shut down. Whenever I go to boot now, I can select my install via Grub and it loads up to where the sign-in should happen, but I get a display that looks like what you see as soon as you shut down. It looks like it locks after checking for the battery. Is there anyway, with or without Live media, to restore my machine's install/update to 12.04 but still keep my settings/applications/files?

• What is the best unit test framework for .NET and why?

  - by rmx

  It seems to me that everyone uses NUnit without even considering the other options. I think this is because: Everyone is familiar with it already so they won't have to learn a new API. It is already set up with their continuous integration server to work with NUnit. Am I wrong about this? I decided to use xUnit on one of my own projects recently and I love it! It makes so much more sense to me and conceptually it seems like a definite step forward from NUnit. I'd like to hear opinions on which framework is actually the best - not taking into consideration having to learn it or reconfigure your automated testing.

• how to modify another user's .profile from the recovery console?

  - by Pinpin

  Pretty much everything is in the title, really! ;) I installed a few components to compile go programs, and the last step was to add the go directory to the path. Being a total ubuntu noob, I added the line PATH="Path/To/Folder", after the one that was already there. After the first reboot I can no longer log into ubuntu (the screen black-out for a while and then I'm back to the login screen, and the same chime greets me.) I've been able to boot in recovery mode, open the root's profile with vi, but I cant find my other user's profile, nor pretty much anything.. Any hint would be greatly appreciated! Pascal

• Rules of Holes -#1: Stop Digging

  - by ArnieRowland

  You may have heard of the 'First Rule of Holes'. It goes something like this: " When you suspect you might be in a hole, stop digging. " That seems like obvious, and good advice, but what does it really mean? How does the Rule of Holes apply to you? How does it apply to your job? When things are not going right, stop doing the "same ol', same ol'" You find yourself involved in doing the same type of coding over and over. Maybe it's time to stop, step back, take a little time and learn something new....(read more)

• Creating Ubuntu bootable disk on my phone

  - by Aerus

  I want to install Ubuntu 12.04 on my laptop but because I have a complete shortage of writable CDs and DVDs, I wan't to create a bootable USB stick (on Windows). However, the only USB stick I currently have lying around is my HTC phone (HTC Touch HD with 8Gb memory). I was following the Ubuntu guide to create a bootable usb stick with pendrivelinux, however in the last step it shows me that it wants to do more than just copying the .iso file to the USB drive: My question: can I safely proceed without wiping the current OS off my phone (Windows Mobile 6.1) and use it to install Ubuntu?

• Windows Wireless Drivers - Install

  - by Justin Y.

  I have nearly ended my journey of making a dual-boot windows xp and ubuntu computer. Along with version 12.04, came the problem with my NetGear WNDA3100v2 wireless adapter. It wasn't compatible. My last step in my adventure is to install the software called Windows Wireless Drivers. I have internet access on my laptop and a flash drive. It would be preferable to receive a link to this program, because I see no link on the website, and I can't download it from the Ubuntu Software Center. Thanks.

• How do I create a game that runs on Windows, iOS and Android?

  - by AspaApps

  I use C++ to create windows games and now I want to step into another other OS like Android or iOS. I'm totally familiar with C++ so I tried to create app for iOS using objective C it was working awesome. However, I also want to publish games for Android but not by using Java. I don't want to create a single game 5-6 times for other platforms. Is their any way that if I create game for Windows then it will work in Android and iOS ? Or should I use Action Script 3.0? If I use action script 3.0, will it require Flash player to run the game in Windows, Android, iOS?

• What kind of authorization I should use for my facebook application

  - by JSmith

  I am building a social reader Facebook application using Django where I am using Google Data API (Blogger API). But I am unable to deal with the authorization step to use the API (currently using ClientLogin under development). I tried to read the OAuth documentation but couldn't figure out how to proceed. I don't want my users to provide any login credentials for google.. which makes the app completely absurd. So, can anyone help me on my project and tell me what kind of authorization I should actually use and how ? (I am using gdata lib)

• XML/XSL Module 04.03.05 is now officially released.

  XML/XSL Module 04.03.05 is a maintenance release. Download is available from Codeplex. Changes were required to fix issues caused by conflicts with a new namespace in DotNetNuke 5.3. as the XML module did not use fully qualified namespaces everywhere. Please upgrade to XML 4.3.5 before upgrading your DNN version to 5.3.1 and above. In case you missed this step and the entire application runs into a Yellow Screen of Death, the easiest workaround is to simply delete ~\App_Code\XML\Handlers\download.vb....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Mouse pointer position to screen space

  - by Ylisar

  If I have a mouse pointer position in pixels of canvas, I can easily convert it to the -1..1 range for both X & Y by lerping by dividing with canvas dimensions. However, the problem is what I should put in Z & W if I want my screen space position to be on the near plane? The step afterwards would be for me to multiply by the inverse of view-projection to take me to world space, where I easily can construct a ray from the cameras world space position.

• How to program a cutting tool for 3D model in game

  - by Jesse S

  I'm looking for a resource to figure out how to program a function to cut a 3d model in game. Example: Enemy/NPC is sliced into 2 pieces with a sword. His body is not hollow, you can see bloody texture where normally a 'polygon hole' would be. The first step is to actually 'cut/slice' the model, then add in polygons to fill the hole in the model. I know this can be done in 3D modelling software, but I'm not sure how to go about doing this in a game, code-wise. I do not wish to use 'pre cut-up" models, the code will determine where the cut is. Any pointers in the right direction would be greatly appreciated.

• Upload image file: is compression on client side already possible?

  - by Chris

  When offering photo file uploading, usually the user will have badly compressed and huge (10+ megapixels) JPEG files from their cameras or phones. On the server side, these files will get re-compressed to something like 800x600px and JPEG quality 7 or 8. Is it (already) possible to do that re-compression on the client side? So that I would only need to transmit some 100kB (800x600px) and not 3 MB or more. Something like: (1) With javascript's new FileSystem API ( http://slides.html5rocks.com/#filewriter ) it would be possible to read the photo file's data into client side JS. (2) Then it would be necessary to re-encode the JPEG data, which is possible, but I counld not find any library for that (yet). Anybody knows such a library? (3) Last step would be to POST the re-compressed JPEG data to the server side for storage and get a URL to the stored photo file back from the server for inclusion into the client's HTML. I am looking for some jQuery plugin, other JS library or example web page that does this.

• How to get familiar with "what happens underneath of Java"?

  - by FidEliO

  I did not study CS nor IT. I just became a developer, now working with Java. Actually, since I now work with a big company writing high-scalable web applications, I think I need to be better with details. I have no understanding of what happens underneath of Java. Java Performance, Server-Side Java might be the buzz words?!! I am very poor with those more of low-level details but I do not know where to look honestly. I started looking for some keywords in Amazon, ended up reading books like "pragmatic programmer", "clean code", "code complete" which IMO they are not what I am looking for. Could you please give me some learning resources (books, articles, blog posts, online trainings) for this matter? I also read this post as well: Approaching Java/JVM internals But I think I need a pre-step before jumping into the OpenJDK, right?!

  I have tried to install a special ATI driver using a method described in http://debianhelp.wordpress.com/2012/09/28/to-do-list-after-installing-ubuntu-13-04-aka-raring-ringtail-operating-system/ Details: Alternative ATI Legacy Video Driver PPA installation for (for < 5000 series cards): sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev* sudo add-apt-repository ppa:makson96/fglrx sudo apt-get update sudo apt-get upgrade sudo apt-get install linux-headers-generic fglrx-legacy sudo aticonfig --initial And then reboot.

• VirtualBox - Install Windows 7 freeze on expading files

  I'm using Kubuntu 12.10. I have the latest version of VirtualBox(4.2.4) with expansions installed and guest addition also. I'm trying to install Windows 7 but it freezes at the second step: expanding files (random percent). I even tried to install Vista but is happening the same thing. Is there a bug? Do you happen to know a workaround? Or at least there is another free virtual machine I can use to install win 7?

• Learning programming

  - by user65862

  I am a senior & am a retired R.N., always good at math (50+ yrs ago, but still am). I have been in a computer users group since the mid 90's, & have become moderately advanced in using computers, including trouble-shooting other people's computer problems. Most of my expertise was gained by reading, asking questions, & trying my own trouble-shooting with the help of books & the internet. Now,I would like to take the next step and learn programming. What would be the best way for me to learn programming? Attending classes isn't a practical option, and I'm not in a position to spend much money. Any ideas would be greatly appreciated. Thank you.

• Programmer, software engineer, computer scientist What's the difference? [closed]

  - by ForgottenKahz

  Possible Duplicate: What are the key differences between software engineers and programmers? What's the difference between computer science and programming? Whats the difference between a Software Architect, a Software Engineer, and a Software Developer (Programmer)? What is the actual difference between Computer Programmers and Software Engineers? Is this description accurate? What's the difference between computer science and programming? I want to know the difference between a programmer, a software engineer and a computer scientist. I'm new to the scene and I don't want to step on anybody's toes. I once gloated to a programmer that I was learning MS Access. Boy, was that a mistake. But when my father in law contracted some of his work out to software engineers their code was junk. In the world of software development, who goes by what title? Does it matter?
