Today Ubuntu Linux 8.10 final will be released to all mirrors world wild. However, FTP/HTTP mirrors server may down due to heavy demands from users. You can now use BitTorrent to upgrade Ubuntu Linux to 8.10 from old 8.04 version. Help Ubuntu project to spread Linux to humanity.

In the past, the update servers would crash very quickly on a big release day, making it hard for people to get the latest update. With BitTorrent, however, this can be easily avoided.

Most users of Linux based operating systems such as Ubuntu are familiar with BitTorrent. In fact, Ubuntu even comes with a BitTorrent client, and millions of Ubuntu users got their install disk via the popular filesharing protocol.

Nice introduction to SELinux and other option to enhance Linux security. Mandatory access control and role-based access control are relatively new to the Linux kernel. With the introduction of the LSM framework, new security modules will certainly become available. In addition to enhancements to the framework, it's possible to stack security modules, allowing multiple security modules to coexist and provide maximum coverage for Linux's security needs. New access-control methods will also be introduced as research into operating system security continues. From the article:

Linux has been described as one of the most secure operating systems available, but the National Security Agency (NSA) has taken Linux to the next level with the introduction of Security-Enhanced Linux (SELinux). SELinux takes the existing GNU/Linux operating system and extends it with kernel and user-space modifications to make it bullet-proof. If you're running a 2.6 kernel today, you might be surprised to know that you're using SELinux right now! This article explores the ideas behind SELinux and how it's implemented.

gNewSense is derived from Ubuntu Linux, and has most of the same functionality. However, it removed all the non-free blobs from distro i.e. it only ship with free and open software. It has no proprietary modules or software:

* Firmware removed from kernel in main
* Builder, a tool to produce a distribution
* Restricted removed
* Ubuntu logos replaced
* Universe enabled by default
* emacs, bsdgames, nethack and build-essential part of the default install

Canonical Ltd. and Red Hat, Inc. today announced the inclusion of OpenJDK-based implementations in Fedora 9 and Ubuntu 8.04 Long Term Support (LTS) Server and Desktop editions, furthering the promise of Sun's open source Java technology initiative.

In addition, the NetBeans 6.0 Integrated Development Environment (IDE) () is being delivered as part of the Ubuntu 8.04 LTS release and Canonical has certified Ubuntu 8.04 LTS Server Edition on several Sun x86 systems.

Great news!

Ministry of Education from Brazil is buying 90,000 Debian GNU Linux computers. The software installed on these systems is "Linux Educational 2.0", a very clean Debian-based distribution, with KDE 3.5, KDE-Edu, KDE-Games, and some tools developed by the project.

By the end of this year 29,000 labs serving some 32,000,000 students will be fully deployed and in active use.

By the end of next year (2009) those numbers will have swelled to 53,000 labs serving some 52,000,000 students.

Another interesting article with security in mind. From the article:

You're probably familiar with the live CD concept -- a fully functional operating system on a CD that can be run on any computer that boots from its optical drive, without affecting the one(s) already installed. In a similar vein, you can set up Linux to run from a USB hard drive drive on any computer that can boot from USB. The live system offers automatic detection and configuration of the display adapter and screen, storage devices, and other peripherals. A bootable USB drive can run a mainstream Linux distribution such as Debian GNU/Linux, and can be secured, personalised, upgraded, and otherwise modified to suit your needs.

This is a philosophical post on why Linux hasn't grown to challenge Windows as the most popular operating system. From the blog post:

Linux isn't very popular on the desktop. It's a far third behind OS X, which is a very far second behind Windows. Most people cite pre-installed operating systems as the reason. But as a student of psychology, I see something most people don't. There's one big factor in why Linux isn't popular on the desktop. Linux is free. I know this sounds like complete dog's bollocks, but hear me out before judging my sanity.

My personal experience suggests that people don't use GNU/Linux on desktop because :

  1. Steep learning curve
  2. Software incompatibility or doesn't run the software they want
  3. Installing and obtaining drivers may be issue for average joe
  4. Finally, human psyche is complex subject. There are people who buy expensive apple hardware and install Linux on it. You just can't predicate human behavior.

I use Linux on desktop because I work with a Linux / UNIX server all day and I find that using it on the desktop as well actually makes my life easier. You know one-size-fits-all approach may be unrealistic in a real life. I see my workplace desktops fully loaded with mix of Linux, OS X and dominated by Windows XP pro.
