Ubuntu Opportunistic Developer Week announced

Ubuntu Opportunistic Developer Week is a week of sessions aimed at enabling and inspiring opportunistic developers to write applications that scratch their itches.

The Ubuntu Opportunistic Developer is Ubuntu Community Manager Jono Bacon‘s pet project. The idea behind the project is to enable developers to write quick, scratch-an-itch application and making development on Ubuntu fun and more accessible.

Jono declared Project Awesome Opportunity first on his blog where he explains how to get started using “Ground Control”, an integration of Bazaar with Nautilus file manager by Martin Owens and “Quickly”, a fast way to start developing applications on Ubuntu by Rick Spencer and Didier Roche.

Jono announced Call for Paricipation for Ubuntu Opportunistic Developer Week yesterday, which will be happening online between 1st and 6th March.

Like Ubuntu Developer Week and Ubuntu Open Week, the Ubuntu Opportunistic Developer Week will be conducted over IRC on the irc.freenode.net server.

The #ubuntu-classroom will be the channel where the talks be held, with questions being asked on #ubuntu-classroom-chat .

Rick Spencer will be giving two tutorial sessions for absolute Python beginners and Python programmers on the 25th Feb.

The Ubuntu Opportunisitic Developer Week itself will cover topics like :

  • Creating an application from scratch from Quickly
  • Integrated developement workflow with Ground Control
  • Creating stunning interfaces with Cairo
  • Micro-blogging with Gwibber
  • Lernid
  • Create games with Pygames

Lernid, the online tool that Jono Bacon created for connecting to online learning events like Ubuntu Developer Week and Ubuntu Open week can be used for attending Ubuntu   Opportunistic Developer Week as well.

Google Implements ext4 filesystem on their servers

Google, the giant search engine who knows a thing or two about speed, has decided to implement the ext4 as the filesystem for their servers.

In a post to the ext4 developer’s mailing list, Senior Engineer Michael Rubin explains that Google had been deciding upon a filesystem upgrade to their existing filesystem, and after a lot of performance testing of the available filesystems, including   xfs, ext4 and jfs, they came to a conclusion that ext4 was best suited to their needs. Although xfs performed close to ext4, the deciding factor on ext4 was that it provided an easy upgrade path from their existing ext2 filesystem to ext4.

ext4 has become the default filesystem for several of the popular Linux distributions including Ubuntu, Fedora and openSUSE and had become an official part of Linux kernel since Linux 2.6.28 kernel. ext4 features several improvements over its predecessor, amongst which include support for files upto 16 tebibytes ( 1 tebibytes equals 1,024 gibibyes , with 1gibibyte equal to 1.074 gigabytes) and a maximum volume size of upto 1 Exbibyte. Other features of the ext4 are backwards compatibility with ext2/ext3 filesystems, and a subdirectory limitation of upto 64,000 subdirectories, and an online defragmentation tool which is still under development stages, however.

Interestingly, one of ext4’s lead developer, Theodore Ts’o is also a Google employee, notes SJVN indicating that Google would most likely use his expertise in further getting even more performance out of an already fast filesystem.
