[Ubuntu] [Solved] Locale problem

After installing Ubuntu server, you might encounter some problems with linux locale configuration. Usually you can see the following warning messages:

Please check that your locale settings:
    LANGUAGE = (unset),
    LC_ALL = (unset),
    LANG = "en_US.UTF-8"

The output of the command “locale” may contain the following lines:

user@server$ locale
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

Here is the solution that worked for me.

  1. Run command sudo apt-get install language-pack-en
  2. sudo dpkg-reconfigure locales
  3. Log out / log in.

Ctrl+Space doesn’t work in NetBeans [Ubuntu 12.04] [Solved]

I reinstalled Ubuntu on my laptop recently. Now I am using Ubuntu 12.04 LTS with Gnome 3 environment. Everything worked fine except one problem: the hot key Ctrl+Space (auto code completion) stopped working in Netbeans and other IDE. Of course, there was an alternative key combination Ctrl+’\’, but it is absolutely inconvenient! I’d prefer to kill myself looking for the solution on the Internet rather than to give in and use Ctrl+’\’. I’ve surfed the net for a while and found a solution to my problem!

The key combination didn’t work because some other program used it. To fix this I used gconf-editor.

  1. Open gconf-editor.
  2. Choose desktop -> ibus -> general -> hotkey.
  3. Open trigger parameter.
  4. Remove Ctrl+Space key combination from the list and press OK.

Now we can use Ctrl+Space without any problems. Let me know if you have any problems or/and better ideas. Good luck!
UPD: I returned to Ubuntu 11.10, cuz’ 12.04 turned out to be a total rubbish. I’m just wondering if Ubuntu 12.10 is any better…

How to install MPI in Ubuntu

I am starting a series of articles devoted to distributed computing that we are now studying at MIPT. For programming we will use MPI.

Message Passing Interface (MPI) is a standardized and portable message-passing system designed by a group of researchers from academia and industry to function on a wide variety of parallel computers. The standard defines the syntax and semantics of a core of library routines useful to a wide range of users writing portable message-passing programs. We can use it for creating programmes for distributed computing systems (parallel computing).

MPI is a standard. There are different implementations of MPI for different platforms and programming languages. This article is about how to install MPI platform to your Ubuntu.
