Craciun Dan — Sat, 11 May 2013 13:33:55 +0000

You can enable TAB auto-completion for APT packages in Debian easily. As root, edit the /root/.bashrc file and add the following line at the end:

source /etc/bash_completion

Exit your Bash session and open a new one and it should work now (or you can source this file again using source /root/.bashrc, just make sure you are doing all this with root privileges.)

Tip of the Day: Make Your Own AssaultCube Server

Craciun Dan — Sat, 11 Jun 2011 22:50:33 +0000

AssaultCube is a popular cross-platform first-person shooter with pretty low hardware requirements, with a fast gameplay and many modes – including the classic CTF, TDM, FFA, or the popular TOSOK (Team One Shot One Kill), LSS (Last Swiss Standing), or HTF (Hold the Flag).

Starting a server should be pretty straightforward in Linux, all you have to do is run the server dedicated binary with several parameters, however AssaultCube provided a script, called server.sh for doing it. Here’s an example:

./server.sh -c20 -xserverpass -Bconfig/serverblacklist.cfg -n"Public AC Server" -o"Welcome to our AssaultCube server!"

This is a perfectly working example, and you will be able to see your server listed in the Server Browser under the name “Public AC Server”. Here is what the switches used mean:

-c20 – the maximum number of clients allowed (20)

-xserverpass – the admin password (-x is the switch and serverpass is the actual password)

-Bconfig/serverblacklist.cfg – the -B switch specifies the blacklist file (banned IPs), in this case config/serverblacklist.cfg

-n”Publci AC Server” – the name of the server, which will appear in the Server Browser, you can use the slash (\) to escape characters like $

-o”Welcome to our AssaultCube server! – this is the welcome message which will be displayed to each player after he joins the server

For a complete list of parameters, see this page on the official website.

Tip: Get Back Volume Tray Icon (and Default Tray Icons) in Ubuntu 11.04

This is a quick, simple tip (but maybe no very obvious for the first time) for getting back the volume control tray icon in case you removed it by mistake.

The volume control tray icon is actually included in the “Indicator Applet”, together with the Internet connections and the chat/mail/messenger icons, rather than being available by itself. To add it back to the panel:

Right click on the panel, click Add to Panel…:

Now select Indicator Applet from the list and click the Add button.

Here it is:

Notice that you can get all the default icons by adding the Indicator Applet Complete applet:
