  • I had Ubuntu 6.04 and there were many errors about Audio drivers and devices not working. I turned it off and that was it at the time.

    Now that I have upgraded to Ubuntu 8.04 (avoiding the bug in October Debug in regard to a huge error in generating an SSL key and all of that!), I thought I'd try again.

    I use VLC so I tried to run with that. I could see the audio equalizer so I thought that it should be working and we should hear the audio... but nothing at all. And VLC would spit out an error about the pulse audio deamon not working properly:

    Error 16

    Today I got an error 16 with GRUB on one of my machines. This had happened before so I did not worry too much. It is just quite annoying.

    Ubuntu CD

    A Ubuntu boot CD has a cool feature one can use to rescue such a system (i.e. re-install GRUB properly.) More or less, boot the CD, select the rescue mode, let it do its things for a moment (after you select options like keyboard, etc.)

  • Getting the OS

    First go to http://www.ubuntu.com and get the latest version you're interesting in. They offer server version that they support for 5 years or so. I suggest one of those if you want to run a server. This is an ISO, in generate around 600Mb so be ready to wait a few hours... Even with a really fast connection, because the transfer will be limited by the mirror in most cases.

    WARNING
    Unless you know better, I strongly suggest you get the Ubuntu Server version. Maybe a bit more annoying to use BUT it works on ALL computers. And ...
  • Well, first... what is RAID?

    Loads of very detailed info are available on Wikipedia. Just in case, it means: Redundant Array of Independent Disks.

  • As I am working on our Snap! C++ CMS, I created a set of virtual systems to test the compilation on "clean" system (yeah! my main computers has all sorts of things that I don't even know about...)

    In those virtual system, I only install the basic server and then do a sudo apt-get install of anything else the server needs to get compiled. This includes libraries such as libmagic, boost, and Qt and some tools like xmllint. This is pretty cool, but when working in a console, and that console is very small, it makes it a bit difficult, so I looked into making it big.

    For this ...

  • How to install your system to be able to boot from any Operating System

    Problems

    Problems with booting... numerous emails & posts about this one, that's for sure!!! Real solutions? Not really... In many cases people end up reinstalling their system from Scratch and once in a while even that doesn't work! But smart people have a way to fix their boot sectors without too much hurdle (instead of the hours it takes to install an OS.)

    Yes! There ought to be a reason for things not to work so well once in while. In most cases, if you only have proper ...

  • Always wondered how they automatically restart an application after a reboot under MS-Windows?

    There is a function named RegisterApplicationRestart() that does just that.

    There are flags to tell when your application should be started or under which circumstances.

    For instance, you can start only if something crashed the OS.

  • The Error: pivot_root not found

    Debian or Ubuntu and pivot_root and GRUB and hard drives... In general, I like Linux, but once in a while, it generates quite a few problems!

  • I just received my new D-Link USB wireless dongle to connect my Linux system to my wireless network...

    I looked like it was detected as the device was flash and lsmod showed all sorts of USB entries as expected (with the correct device number, something like 2800.)

    But the thing would not connect.

    Looking at the log I had a message saying "networking is disabled by state file". This came from the Network Manager which was indeed disabled! Editing the following file:

    /var/lib/NetworkManager.state

    and changing the NetworkingEnabled variable from false to true made everything ...
