FreeBSD 7.2RC Released

Posted on in Categories FreeBSD, Hardware, Howto, Networking, News last updated January 25, 2009

The second of two planned Release Candidates for the FreeBSD 7.2-RELEASE cycle is now available. ISO images for Tier-1 architectures are now available on most of the FreeBSD mirror sites.

The freebsd-update(8) utility supports binary upgrades of i386 and amd64
systems running earlier FreeBSD releases. Systems running 7.0-RELEASE,
7.1-RELEASE, 7.2-BETA1, or 7.2-RC1 can upgrade as follows:

# freebsd-update upgrade -r 7.2-RC2

During this process, FreeBSD Update may ask the user to help by merging
some configuration files or by confirming that the automatically performed
merging was done correctly.

# freebsd-update install

The system must be rebooted with the newly installed kernel before continuing.
# shutdown -r now

After rebooting, freebsd-update needs to be run again to install the new
userland components, and the system needs to be rebooted again:

# freebsd-update install
# shutdown -r now

Google Chrome 2.0 Early Access Version Is Here

Posted on in Categories Linux desktop, Mozilla, News, OS X, UNIX, Windows, windows vista last updated January 9, 2009

Google Chrome is a web browser developed by Google and based on the WebKit layout engine and application framework. On January 08, 2009 Google introduced a new release channels system, and now there are three distinct release channels – Stable channel, Beta channel, and Developer preview channel.

Google has released Chrome 1.0 on Dec – 2008, and now the company is all set to release version 2.0 (pre – beta version) of its web browser. From the release notes:

New version of WebKit. WebKit is the open source code Google Chrome uses to render web pages (HTML and CSS). 1.0.154.36 used basically the same version of WebKit as Safari 3.1, but the WebKit team has made a lot of improvements since that was released. 156.1 uses WebKit version 528.8 or, more precisely, revision 39410 from the WebKit source tree. In addition to fixing bugs and enabling features like full-page zoom and autoscroll, the new version also enables some nifty CSS features.

New network code. Google Chrome now has its own implementation of the HTTP network protocol (we were using the WinHTTP library on Windows, but need common code for Mac and Linux). We fixed a few bugs in HTTP authentication and made Google Chrome more compatible with servers that reply with invalid HTTP responses. We need feedback on anything that’s currently broken, particularly with proxy servers, secure (https) sites, and sites that require log in.

Look like the Mac and Linux versions of Chrome are getting closer. Are you going to switch to Google Chrome under Linux?

Important: Openssl Security Update [CVE-2008-5077]

Posted on in Categories CentOS, Debian Linux, fedora linux, FreeBSD, GNU/Open source, Howto, Linux, News, RedHat/Fedora Linux, Security Alert, Slackware, Suse Linux, Sys admin last updated January 8, 2009

Linux / BSD and UNIX like operating systems includes software from the OpenSSL Project. The OpenSSL is commercial-grade, industry-strength, full-featured Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as general purpose cryptography library.

The Google security team discovered a flaw in the way OpenSSL checked the verification of certificates. An attacker in control of a malicious server, or able to effect a “man in the middle” attack, could present a malformed SSL/TLS signature from a certificate chain to a vulnerable client and bypass validation.

This update has been rated as having important security impact on FreeBSD, all version of Ubuntu / Debian, Red Hat (RHEL), CentOS, Fedora and other open source operating system that depends upon OpenSSL.

Leap Second To Be Added End Of 2008 And Its Impact On Clustered Computers / Network

Posted on in Categories Hardware, High performance computing, Linux, News, Sys admin, Tips, UNIX, Windows server last updated December 31, 2008

Get ready for a minute with 61 seconds. Scientists are delaying the start of 2009 by the first ‘leap second’ a timing tweak meant to make up for changes in the Earth’s rotation.

The aged Earth is slowing down in its daily rotation, at least in the current epoch. So a leap second is added (a one-second adjustment added) to our time. This year will be exactly one second longer.

Precise time measurements are needed for high-speed communications systems among other modern technologies such as clusters, GPS, networks. You need to make sure that you are running updated version of ntpd that support leap second for UNIX and Windows computers.

New Notification System for GNOME and KDE

Posted on in Categories Gnome, Kde, Linux desktop, News last updated December 24, 2008

Canonical the makers of Ubuntu about to introduce a new desktop notification system proposal. New changes should improve the usability of the Linux desktop including desktop notification system for both GNOME and KDE. From the Mark Shuttleworth blog:

The key proposals we are making are that:

* There should be no actions on notifications.
* Notifications should not be displayed synchronously, but may be queued. Our implementation of the notification display daemon will display only one notification at a time, others may do it differently.

That’s pretty much it. There are some subtleties and variations, but these are the key changes we are proposing, and which we will explore in a netbook device with a partner, as well as in the general Ubuntu 9.04 release, schedule gods being willing.

I think new changes looks more like Growl system used in Mac OS X. You can read more about proposal including mockup video that shows new notification system here.

Seasons Greetings!

Video Contest: I am Linux

Posted on in Categories Linux, Linux desktop, Linux distribution, News, OS X, Windows, windows vista last updated December 21, 2008

The Linux Foundation is launching a video contest and you can win yourself a trip to Tokyo next year to participate in the Linux Foundation Japan Linux Symposium Oct, 2009.

If you’ve been alive and aware of mass media over the last twelve months, you’ve probably seen television commercials from Apple and Microsoft touting their operating system. From Apple’s ubiquitous “I’m a Mac” to Jerry Seinfeld to Microsoft’s “I’m a PC” retort, operating system commercials have been flooding the airways. Except one OS has been notably absent — Linux.


You can upload your contest video here.

Yet Another Reason To Get Open Source Software

The USB Overdrive is a device driver for Mac OS X that handles any USB mouse / trackball / joystick / gamepad and any Bluetooth mouse from any manufacturer and lets you configure them either globally or on a per-application basis. Some one posted a screen shot of USB Overdrive software. If you are a sensitive pirate you might feel guilty (found via Digg). Maybe it is a time to switch to Linux.
