Aug. 6, 2014, 9:42 p.m. by Nathan Osman

If you've been following 2buntu for any length of time, you've probably noticed that our servers rarely go down. Our system administrators do an excellent job of staying on top of server issues, although they are quite rare. Unfortunately, it is not always possible to avoid downtime. (At least, not with our budget or equipment.) Services need restarting, configuration files ...

XBMC gets renamed to Kodi.
Aug. 2, 2014, 11:34 a.m. by Amith KK

The popular media center XBMC, which started out as a media center for the Xbox, finally got renamed to Kodi Entertainment Centre from version 14("Helix") onwards. The rename was inveitable since the name XBMC no longer makes sense as it barely runs on the Original Xbox, and also because there would be legal issues in having xbox in its name. ...

Opera Linux has system border support, more stable than ever
July 17, 2014, 11:25 a.m. by Roland Taylor

Well, kind of. As of the latest release, 24.0.1558.3, Opera on Linux has support for system borders, but it seems to only work if you are running under a session other than Unity. Also, Under Unity, you still get right aligned Window controls no matter what setting you've chosen. This should be terribly hard to get used to, but it ...


Monitoring webpages with Last-Modified and ETag headers
July 14, 2014, midnight by Nitin Venkatesh

Most sites have a lot going on in their HTTP headers which can sometimes help us easily identify if the web page has changed since the last time we visited it. This ofcourse depends on if the server responds with these headers and has been configured correctly to reflect any changes in the headers. Enough said, so when we query ...


Viewing text files on Linux - cat, head, tail, more and less
July 4, 2014, 6 a.m. by Nitin Venkatesh

A lot of times, we have the need to view text files on a Linux box, whether it be logs or scripts or what have you. This post is more like a cheat-sheet for me on using the cat, head, tail, more and less commands, but with examples and some screenshots. Short version head <filename>- View the top few lines ...

Audacity, FFMpeg and Libav
June 5, 2014, 12:16 p.m. by Roland Taylor

Audiophiles on Ubuntu, breathe a collective sigh of relief. After much frustration, there is finally a solution to the lack of FFMpeg support in Audacity. Apparently, the problem lay not in Debian/Ubuntu's move from FFMpeg to the much contested fork, but in Audacity's own usage of an outdated version of FFMpeg. However, a new patch has landed, and will be ...

Robert Roth, a Gnome developer, has created a usable clone (in Vala) for the Linux desktop. Along with that, he's written a tutorial for fellow coders (integral with the code as comments). The entire application ...
