  • How do I get to the maintenace shell?

    - by Narida
    I'm asking this because initially, my problem was this (power failure during installation, so I typed the following instructions in the maintenance shell: sudo mount -o remount,rw / sudo dpkg --configure a sudo mount -o remount,ro / sudo sync sudo reboot The first three lines worked, afterwards, my computer (a Dell Inspiron 530) got stalled for several hours, so I unplugged it. When I turned it on, the log in screen appeared, and after I try to write my password, it leads me back to the log screen. I must note that when I typed the first three lines during the maintenance shell mode, it said that the errors which were encountered during processing were: initscripts bluez gnome-bluetooth So, what do I have to do in order to get back to the maintenance shell so I can type code again? And, what code do I have to write in order to restore my computer? Thank you for your attention.

We're setting up a lab of 10 Mac machines in which you will be able to develop iOS on-device applications.  And the great thing is, if you want to develop for Android, its the same lab as well!  Just think, write once and deploy to iOS or Android.  We know places will be limited so we are going to be putting in place a first-come-first-served booking system.  Walk-ups will be allowed only if places are free. This is your chance to start skilling up on the hottest development initiative in years.

  • How to run a complete GUI as root?

    - by Braiam
    I don't care if I mess up the system (which is likely if I do things like this), or the potential security issues that this could imply. Note, that I don't just want to "enable root login?", but run my GUI from bottom-up as root. I don't want to type my password for anything but just for login and have total control over it. Of course, I want any application running as root, like Firefox, LibreOffice, etc. without having to mess up with the terminal. So, how do I do this?

  • Did You Know Facebook Has Built-In Shortcut Keys?

    - by The Geek
    I was spending some time browsing around Facebook today (translation: wasting time), when I noticed that they have some shortcut keys for navigating around the site using the keyboard, so I put together a list for everybody. Note: for each of these shortcut keys, if you’re using Firefox, you’ll need to use Shift+Alt instead of just Alt, and for Internet Explorer you’ll need to hit the Enter key after the shortcut to trigger it. If you’re using a Mac, you’ll need to use Ctrl+Opt instead of Alt Latest Features How-To Geek ETC How To Boot 10 Different Live CDs From 1 USB Flash Drive The 20 Best How-To Geek Linux Articles of 2010 The 50 Best How-To Geek Windows Articles of 2010 The 20 Best How-To Geek Explainer Topics for 2010 How to Disable Caps Lock Key in Windows 7 or Vista How to Use the Avira Rescue CD to Clean Your Infected PC 2011 International Space Station Calendar Available for Download (Free) Ultimate Elimination – Lego Black Ops [Video] BotSync Enables Secure FTP File Synchronization on Android Devices Enjoy Beautiful City Views with the Cityscape Theme for Windows 7 Luigi Installs Any OS on Google’s Cr-48 Notebook DIY iPad Stylus Offers Pen-Based Interaction on the Cheap

  • How to add a command permanently to grub2

    - by tomodachi
    I have a fairly special setup, using Linux on a MacBook Laptop. to switch off my secondary graphics card in it I'm required to add these lines to my grub outb 0x728 1 outb 0x710 2 outb 0x740 2 outb 0x750 0 I do this by pressing 'e' for my selected grub menu option and adding the lines one by one . then finally booting . But as we know it's not permanent. I cant really figure out where i need to add it for grub to always append it to my Linux boot options. It's doesn't seem to belong in /etc/default/grub since here i can add stuff to the kernel boot line Honestly i'm afraid to fiddle to much with grub on my computer since getting it to triple boot Linux/Mac/Windows was a very delicate and timely matter. Does anyone have any idea of where to add it?

  • What's the difference or purpose of a file format like ELF when flat binaries take up less space and can do the same thing?

    - by Sinister Clock
    I will give a better description now. In Linux driver development you need to follow a specification using an ELF file format as a finalized executable, i.e., that right there is not flat, it has headers, entry fields, and is basically carrying more weight than just a flat binary with opcodes. What is the purpose or in-depth difference of a Linux ELF file for a driver to interact with the video hardware, and, say, a bare, flat x86 16-bit binary I write that makes use of emulated graphics mode on a graphics card and writes to memory(besides the fact that the Linux driver probably is specific to making full use of the hardware and not just the emulated, backwards compatible memory accessing scheme). To sum it up, what is a difference or purpose of a binary like ELF with different headers and settings and just a flat binary with the necessary opcodes/instructions/data to do the same thing, just without any specific format? Example: Windows uses PE, Mac uses Mach-O/PEF, Linux uses ELF/FATELF, Unix uses COFF. What do any of them really mean or designate if you can just go flat, especially with a device driver which is system software.

  • G5 quad core will not boot from Ubuntu CD

    - by Steve Howard
    I have a PPC G5 Quad Core with Leopard on one hard drive and I want to install Ubuntu on a second hard drive. The second drive is installed and formatted as a Mac OS Extended (Journaled) drive. I have had no success booting from a CD or DVD with various PPC versions of Ubuntu using any of the suggested keys such as "C, Option, or anything else. Booting into open firmware doesn't work as the system can't find the \install\yaboot file. I am using various CD's burned as iso disk images, but none will boot. I have reset the PRAM, etc, to no avail. Beginning to get very frustrated. Can someone shed some light and provide me with a command line in open firmware that will work, or else direct me to a confirmed PPC bootable version of Ubuntu please? I'd appreciate any help you can provide....

  • Can't login to Ubuntu One

    - by Gabriel
    I uninstalled Ubuntu One about two months ago and now I re-installed it. I can still login with my account through the site (Ubuntu One) but the client keeps telling me "The authentication failed". If I try to use the Recover password option it also fails with telling me that my email address is not recognized (while I can use it with zero issues through the site) If I attempt to create a new account from the client, it also fails to load the captcha every time. Something is clearly broken here but I can't figure out what it is. Any ideas?

  • How to automatically mount a Windows shared folder on every boot up?

    - by Zabba
    I am able to access Windows' shared folder from Ubuntu 10.10 Nautilus like so: Type into the Location Bar : smb://box/projects Now, I can see the folder in Nautilus, create/read files in it. Also, on desktop I get a folder called "projects on box". But, that folder on the desktop goes away when I reboot. So, I thought that I can automount the Windows' shared projects folder by adding this to my fstab: //box/Projects /home/base/Projects smbfs rw,user,username=jack,password=www222,fmask=666,dmask=777 0 0 (base is my user name on Ubuntu) Now, I get a folder called "Projects" in my home folder after boot up, but it is empty (cannot see the same files that I can see in Nautilus). What's am I doing wrong? Some more detail: This is what I see of the Projects folder when I do ls -l in my home folder: ... drwxr-xr-x 2 root root 4096 2011-01-01 10:22 Projects drwxr-xr-x 2 base base 4096 2011-01-01 09:06 Public ... Note the two "roots". Is that somehow the problem?

  • Can data classes contain methods for validation?

    - by Arturas M
    OK, say I have a data class for a user: public class User { private String firstName; private String lastName; private long personCode; private Date birthDate; private Gender gender; private String email; private String password; Now let's say I want to validate email, whether names are not empty, whether birth date is in normal range, etc. Can I put that validation method in this class together with data? Or should it be in UserManager which in my case handles the lists of these users?

  • iTunes 7 can't find iPod in PlayOnLinux using Ubuntu 12.04 Precise?

    - by Endia
    I'm using 12.04 and the latest version of PlayOnLinux to run iTunes 7. I have my iPod 4th gen plugged in and the computer recognizes that it's mounted but it's not showing up in iTunes for me to do anything with it. I know there have been a lot of issues with being able to access your iDevices in iTunes from Linux when you're using a compatibility layer like PlayOnLinux or Wine (both of which I have), so it's recommended that I use Rhythmbox to back up my music etc. Which is fine, because that's part of what I need to do, but my primary need in trying to access my iPod in iTunes is that I need to remove my backup password so that I can jailbreak my iPod with the new Absinthe jailbreak. If there is some other way I can do this without iTunes you know of, I'd love to hear it. If not, what can I do?

  • What could be a reason for cross-platform server applications developer to make his app work in multiple processes?

    - by Kabumbus
    We consider a server app development - heavily loaded with messing with big data streams. An app will be running on one powerful server. A server app will be developed in form of crossplatform application - working on Windows, Mac OS X and Linux. So same code, many platforms for stand alone server architecture. We wonder what are the benefits of distributing applications not only over threads but over processes as well, for programmers and server end users? Some people said to me that even having 48 cores, 4 process threads would be shared via OS through all cores, is that true?
