• Installer script removed a buch of 64-bit files and replaced them with 32-bit ones, how do I get them back?

  - by ILikePizza555

  I ran this installer script to get some drivers for my printer, however I noticed that it started removing some of my programs, as well as 64-bit system files, and started replacing them with 32-bit ones! Luckily, I managed to cancel the operation before it did any serious damage. I also noticed that offical PPA's for 32-bit files were added. Should I remove them? So how do I get these files back?

• How to remove Ubuntu and put Windows back on?

  - by Josev King

  I installed Ubuntu 12.04, as a dual boot on my windows Vista laptop, and the next thing I know, I get black screen with error: unknown filesystem. grub rescue> I have tried reinstalling Windows, reinstalling Ubuntu, booting from Ubuntu disk, and managed to actually get into the OS, but there is nothing I can find of uninstalling Ubuntu, and deleting the partition it created. I know nothing at all about Linux, and I desperately need to get my laptop back up and running.

• Google Sync brings back Login Keyring from previous distro: How to remove?

  - by Mridul Malpotra

  I previously had Ubuntu 12.04 and had my Login Keyring set to a password that I don't remember and am not able to guess. I changed my Linux version to Mint 15 Cinnamon recently, but everytime I sync my Google account with my browser, the Login Keyring keeps coming back. I tried the /Preferences/Password method but there is no file as such which is created. Also, .gnome2 folder doesn't have any keyring file. How can I make the box go away for all?

• sorting using recursion

  - by user310587

  I have the following function to sort an array with even numbers in the front and odd numbers in the back. Is there a way to get it done without using any loops? //front is 0, back =array.length-1; arrangeArray (front, back); public static void arrangeArray (int front, int back) { if (front != back || front<back) { while (numbers [front]%2 == 0) front++; while (numbers[back]%2!=0) back--; if (front < back) { int oddnum = numbers [front]; numbers[front]= numbers[back]; numbers[back]=oddnum; arrangeArray (front+1, back-1); } } }

• Cloud storage provider lost my data. How to back up next time?

  - by tomcam

  What do you do when cloud storage fails you? First, some background. A popular cloud storage provider (rhymes with Booger Link) damaged a bunch of my data. Getting it back was an uphill battle with all the usual accusations that it was my fault, etc. Finally I got the data back. Yes, I can back this up with evidence. Idiotically, I stayed with them, so I totally get that the rest of this is on me. The problem had been with a shared folder that works with all 12 computers my business and family use with the service. We'll call that folder the Tragic Briefcase. It is a sort of global folder that's publicly visible to all computers on the service. It's our main repository. Today I decided to deal with some residual effects of the Crash of '11. Part of the damage they did was that in just one of my computers (my primary, of course) all the documents in the Tragic Briefcase were duplicated in the Windows My Documents folder. I finally started deleting them. But guess what. Though they appeared to be duplicated in the file system, removing them from My Documents on the primary PC caused them to disappear from the Tragic Briefcase too. They efficiently disappeared from all the other computers' Tragic Briefcases as well. So now, 21 gigs of files are gone, and of course I don't know which ones. I want to avoid this in the future. Apart from using a different storage provider, the bigger picture is this: how do I back up my cloud data? A complete backup every week or so from web to local storage would cause me to exceed my ISP's bandwidth. Do I need to back up each of my 12 PCs locally? I do use Backupify for my primary Google Docs, but I have been storing taxes, confidential documents, Photoshop source, video source files, and so on using the web service. So it's a lot of data, but I need to keep it safe. Backup locally would also mean 2 backup drives or some kind of RAID per PC, right, because you can't trust a single point of failure? Assuming I move to DropBox or something of its ilk, what is the best way to make sure that if the next cloud storage provider messes up I can restore?

• How do I get "Back to My Mac" (using MobileMe) from Windows?

  - by benzado

  I have a MobileMe subscription and a Mac at home with "Back to My Mac" enabled. When I'm away from home, this service lets me use another Mac to connect to my Mac back home and access file sharing, screen sharing, etc. As far as I know, the service doesn't use any proprietary protocols, so in theory I should also be able to get "Back to My Mac" from a Windows PC. This MacWorld article explains how it works. Basically, it uses Wide-Area Bonjour to give your Mac a domain name like hostname.username.members.mac.com. Remote computers can find your Mac using that address, then connect to it using a private VPN. The "Wide Area Bonjour" part seems to make it a little more complicated than simply a regular domain name, though. Note that I'm not interested in using the methods described by LifeHacker, which doesn't use the MobileMe service at all. I don't want to use a totally different dynamic DNS service. I'd like to use the one I'm already paying for, or at least find out why that's not possible from Windows. Also, my primary problem is finding a network route back to my mac... once I've got that I know how to enable services so that Windows can talk to it. UPDATE: Based on some additional research, it appears that Apple is only assigning IPv6 addresses to the hostname.username.members.mac.com names. So any solution will require enabling IPv6 support on Windows, if possible.

• Ways to use your skills as a developer to give back to the community/charities.

  - by Ryan Hayes

  Recently I came upon a community event called GiveCamp. GiveCamp is a weekend-long event where technology professionals from designers, developers and database administrators to marketers and web strategists donate their time to provide solutions for non-profit organizations. Since its inception in 2007, the GiveCamp program has provided benefits to over 150 charities, with a value of developer and designer time exceeding $1,000,000 in services! Coming from a very rural part of the country where there is a huge opportunity for charity events like this, it got me wondering. Are there other large movements like GiveCamp that are out there? GiveCamp is sponsored by Microsoft, so of course most are run through .NET user groups. Are there other flavors of it? Different types? Java/Python/other open source charity movements? If not, how do you give back?

• Accidentally uninstalled Ubuntu 14.04 system settings. How to get them back?

  - by Dan

  Somehow, cleaning up useless software (using software center), I uninstalled Ubuntu "system settings". I did this by mistake. Now I fail to find system settings application using software center (and there are so many items in history...). It seems strange to me because usually when I try to uninstall something critical (system testing for example), the dependencies manager tells me It will uninstall the whole desktop system then. I am sure I did not have that warning. So I need the name of the software to install or a command line command rather than a system restore to get it back. Very interesting thing. If you ever want to play with this and reproduce it, you will be confused to see Ubuntu Mobile system settings instead! Yes, mobile network and touchscreen settings! Happy pre-release viewing!

• Tool to convert from XML to CSV and back to XML without losing information?

  - by Lanaru

  I would like to convert an XML file into CSV, and then be able to convert that CSV back into the original XML file. Is there a tool out there that makes this possible? The reason I want to do this is that I want to generate a ton of data to be stored in an xml file that my program will parse. I can easily generate a lot of data with a CSV file through the use of Excel macros, so that's why I'm looking for a tool to convert between these two formats. Any alternative suggestions are greatly appreciated.

• projected textures not appear on the "back" of the mesh as well?

  - by user975135

  I want to create blood wounds on my character's bodies by using projected textures. I've watched some commentaries on games like Left 4 Dead and they say they use projected textures for the blood. But the way projected textures work is that if you project a texture on a rigged character, say his chest, it will also appear on his back. So what's the trick? How to get projected textures appear only on one "side" of the mesh? I use the Panda3D game engine, if that will help.

• How do I remove nitrogen back to Ubuntu's default wallpaper manager?

  - by jonalmeida

  I was using nitrogen when I using openbox, but now I'm trying to stop it from setting the wallpaper so I can use the Ubuntu default (i.e via the System Settings panel). What I've done so far: sudo apt-get remove nitrogen Removed nitrogen configs at ~/.config/nitrogen/ Checked to make sure that draw_background in /desktop/gnome/background was checked So far it still doesn't work. I can't right-click on the desktop, so I'm guessing that I've missed something to get Nautilus back to drawing icons on the screen. Any help is much appreciated. Thanks!

• Coding with laptop and external screen - neck, back, comfort ...

  - by Xorty

  Guess I'm not the only one here coding on laptop + external keyboard + external screen. I can't really decide. Figure 1: Putting screen directly in front of (upright) my eyes and move laptop to the side. That feels like more comfortable but I can't really see so good to 15" laptop which is now quite away. Feels unused. Figure 2: Putting laptop in front of me and move external monitor on side. Feels like more efficient space usage, but I am afraid that my neck/back might start hurting since I need to turn my head often. What do you prefer? Some good advice? Sacrificing health is definitely no option here so that's why I'm worried and asking this silly question. Thanks

• What exercises counter the back pain of sitting at a computer for 15 hours a day? [on hold]

  - by Sam

  I work up to 15 hours a day (not everyday :)) programming. When I do this I get a very sore lower back. I don't want to spend $1000 on a special chair like Joel Spolsky says. I'm sure I'm not alone here. Has anybody encountered this and found an exercise/other method to combat it? Maybe somebody with more physical education than me about opposing muscle groups or something. PS (not working fifteen hours a day isn't an answer, it's how I work best) and it's not off topic as programming is about more than code - it's a verb.

• I removed Ubuntu from the BIOS menu but it comes back.

  - by jimirings

  For reasons too long to explain, I reluctantly removed Ubuntu from my computer. After completely removing it and deleting the partition that it was installed onto, I discovered that I still had two Ubuntu entries in the boot order in my BIOS menu. I deleted them by following the instructions in this answer: http://askubuntu.com/a/63613/54934 As I was doing it, everything appeared to go smoothly. However, upon reboot one of them came back. What's going on here? How do I delete it permanently? I'll gladly provide any other information that may be needed to diagnose the problem. Thanks.

• Laptop suspend appears broken, what must I roll back?

  - by M. Tibbits

  Question: What package contains the subprogram responsible for the KMenu option "sleep"? Background: I've been running KUbuntu 10.04.1 and I am completely updated. Recently (within the past month), the "sleep" menu item has stopped working. It just sits there waiting like I clicked nothing. I've check all of the logs in /var/log and nothing is added when I click sleep. I'm guessing that something I updated has bollux'ed things up, but I don't know which package contains the component that I need to roll back. In the meantime, I've installed uswsusp, but s2ram & s2both don't ask my password when the laptop resumes -- which really bothers me. So now that I've got a little time to track this down, I had to post -- any ideas??

• Get Your Google Back : Google ne veut pas perdre ses utilisateurs sur Windows 8 et explique comment retrouver son univers sous l'OS

  Get Your Google Back : Google ne veut pas perdre ses utilisateurs sur Windows 8 et explique comment retrouver son univers sous l'OS Windows 8 est disponible depuis quelques jours avec de nouveaux PC et tablettes sous le nouveau système d'exploitation de Microsoft. Les possesseurs d'une version de l'OS ont certainement remarqué la mise en avant de Bing et Internet Explorer 10 qui sont respectivement utilisés comme moteur de recherche et navigateur par défaut. Un geste qui ne doit certainement pas être vu d'un bon oeil par les éditeurs des solutions concurrentes. Google, pour sa part, a déjà réagi en mettant au point un moyen de faire retourner ses solutions sur Windows 8.

• Why did windows change the elevation requirements of my AutoHotKey script, and how can I prevent such in the future?

  - by monsto

  I was working on an AutoHotKey (AHK) script to create prefab mouse movements for a very simple model viewer. I worked on it for a good hour. I zipped the script, posted it to a forum, and thought "oh hey, I should add bla bla bla to the script". When I returned to the program, the AHK script would not work. I could see the mouse movements working in other programs (notepad, chrome, etc), but not where I had been working the previous hour. After several hours of throwing darts at the troubleshooting wall, I discovered that the fix was to set the AHK.exe to Run as Administrator. The question here are multiple Why did Windows 7, in all it's wisdom, suddenly decide that elevation was necessary in the middle of usage? Can these permission requirements somehow be reverted by, say, removing a key from the registry or something? How can this kind of Windows behaviour be avoided in the future?

• sudoer scheme for a web developer that retains future control of a server?

  - by Tchalvak

  Background I have a server that I'm looking to set up, and provide access to another web developer. I don't want to put many constraints on him, though I wouldn't mind isolating the site that he'll be developing from others on the server that I will develop. The problem Mainly what I want is to make sure that I retain control over the server in the future. I want to reserve the ability to create/promote/demote and other administrative functions that don't deal with web software. If I make him an admin, he can sudo su - and become root and remove root control from me, for example. What is a good setup for the sudoers file so that he can do things like: *install software (through apt-get) restart apache access mysql configure mysql/apache reboot edit web development configuration type files in /etc * And can't do things like: take away other admin permissions change the root password have control over other security/administrative functions Example sudoer files that accomplish something like that could be useful, I'm sure that people have needed to do this before.

• Can you suggest some DIY PC specs for 1) Value, and 2) Future 'upgradability'?

  - by user17381

  Hi, I'm considering building a new desktop PC from components. For the last 7/8 or so years I have almost exlusively used laptops, and so have fallen behind a bit with knowledge of various hardware technologies. Anyway, now I'm considering building a new desktop machine. Mainly for development work, but also would be nice to do a bit of gaming. The two main criteria are: I would like the first build to be relatively low cost. I would like to select components that will allow me to upgrade in the future without throwing too much away. Can anyone recommend a setup? Thanks

• Does searching a keyword on Google make the crawlers look harder in the future?

  - by Foo Bar

  Do the search requests made by the users influence the Google crawlers "attraction" by this keyword? Let's say Google has some hits on a specific keyword in the search index. And now I search for exactly this keyword. Will the Google crawlers react to the search and keep looking more intense for pages that could match this keyword? A reason why this could be important: Privacy when searching yourself. Assume you just want to know how much Google (and thus other people) can find out about you. If now any (statistical) additional search for your name trigger the crawlers even one step harder to find even more about you, it would have the negative effect that you would actually be found easier in the future, even though you had the intention and hope to find out how few Google finds about you. It's a bit like the dillema in quantum mechanis: Does observing the system automatically change the system?

• iPhone: Core Data: Updating a pre-filled database in future app versions.

  - by Cuzog

  I am creating an app with a database of information that needs to be pre-filled. This data will change in future versions. In the same database, I also need to store user editable information since that user edited data directly relates to the pre-filled data. My question is, if I'm pre-filling the database by creating a duplicate data model in a second app and copying over the core data file before release, how would I handle updates to that data in future versions of the app without destroying the user's existing data? Do the core data migration methods handle this, or must I write custom methods to programatically handle the merge at first app launch?

• iPad as programming platform--What future do touch screens have with programming?

  - by user94154

  I read this question a few weeks ago. I thought about it when I first saw the iPad. Do you think it would be possible to set up a development environment on the iPad? I think it would be awesome if there was an InstantRails App, a Django App, maybe even 280 North's Atlas could run on it :). Would you develop using an on-screen keyboard and a 10 inch screen? Steve Jobs seems to think touch-screens are the future of web browsing. What Future does touch have with programming?
