Ubuntu 9.10 and GNOME 2.28: Advancing Past Meh
Tuesday, February 09, 2010 @ 13:42:15 CET by tw45admin (9 reads)
Ubuntu LinuxMany eons ago, GNOME 1.4 still lived, and it was good. It was extremely configurable and hackable. You could use either Enlightenment or Sawfish as the window manager, and could customize it to your heart's content. It was even friendly to homegrown GTK+ hacks. And then tragedy struck: the GNOME maintainers decided that 1.4 needed a ground-up rewrite, and thus GNOME 2.0 was born. The only thing GNOME 2.0 had in common with 1.4 was the foot. The much-beloved flexibility of 1.4 was gone, gone with the wind, thrown into the bit-bucket without a backwards glance. The new and much simpler Metacity became the new window manager. Features were discarded wholesale in the name of "simplicity." Having no features is the ultimate in simplicity for sure. A number of humorous people created fake screenshots of the ultimate GNOME desktop, which was a blank screen with a single red button in the center labeled DO SOMETHING.

The kernel column by Jon Masters #83
Tuesday, February 09, 2010 @ 13:38:30 CET by tw45admin (8 reads)
LinuxLast month many developers were scurrying to prepare for the 2.6.33 merge window (which we’ll cover in the next time). When they weren’t doing that, here are a few of the items that were under discussion, starting with the Big Kernel Lock. As I’ve mentioned before, one of the longer-term goals of the kernel development community is to kill off the Big Kernel Lock (BKL). This is a stayover from the early days of Linux support for SMP (support for multi-processing) in which the in-kernel locking was very coarse and under the control of a single giant ‘Big’ kernel lock. The BKL continues to exist on some level even today – previous efforts to kill it having been thwarted – and it increasingly harms larger system scalability...

Moonlight 3.0 preview offered for rich Internet apps on Linux
Tuesday, February 09, 2010 @ 13:29:49 CET by tw45admin (7 reads)
InternetMoonlight 3.0, which puts Microsoft's Silverlight rich Internet plug-in software on Linux and Unix platforms, is now being offered in an alpha release, according to Web pages from the Mono project, which has jurisdiction over Moonlight. The release features infrastructural capabilities designed to move Moonlight closer to the capabilities of Silverlight 3, said Novell, which sponsors Mono. In a blog post this week, Novell Vice President Miguel de Icaza, who has been in charge of Moonlight and Mono projects, described the release as the first preview of Moonlight 3.0.

How To Set Up MySQL Database Replication With SSL Encryption On Ubuntu 9.10
Tuesday, February 09, 2010 @ 13:26:58 CET by tw45admin (7 reads)
Ubuntu Linuxfalko writes
This tutorial describes how to set up database replication in MySQL using an SSL connection for encryption (to make it impossible for hackers to sniff out passwords and data transferred between the master and slave). MySQL replication allows you to have an exact copy of a database from a master server on another server (slave), and all updates to the database on the master server are immediately replicated to the database on the slave server so that both databases are in sync. This is not a backup policy because an accidentally issued DELETE command will also be carried out on the slave; but replication can help protect against hardware failures.

HTTP authentication with PHP
Monday, February 08, 2010 @ 22:30:22 CET by tw45admin (42 reads)
PHPThe HTTP Authentication hooks in PHP are only available when it is running as an Apache module and is hence not available in the CGI version. In an Apache module PHP script, it is possible to use the header() function to send an "Authentication Required" message to the client browser causing it to pop up a Username/Password input window. Once the user has filled in a username and a password, the URL containing the PHP script will be called again with the predefined variables PHP_AUTH_USER, PHP_AUTH_PW, and AUTH_TYPE set to the user name, password and authentication type respectively. These predefined variables are found in the $_SERVER and $HTTP_SERVER_VARS arrays. Both "Basic" and "Digest" (since PHP 5.1.0) authentication methods are supported. See the header() function for more information.

Tweeting from the Command Line with Twyt
Monday, February 08, 2010 @ 22:04:30 CET by tw45admin (33 reads)
HOWTOs and similar articlesAs you’ve probably realized by now, I love the command line. Part of the reason for my obsession with the command line is that I work at the command line for most of every day at my day job. With the exception of the few Windows hosts to which I must connect for certain operations, I never see a graphical interface. And, in keeping with my need to stay command line connected, I sought out a command line Twitter client to help me stay current with my all-important Twitter statuses. I chose the somewhat obscure, Python-based Twyt project to use as my Twitter companion.

Marry your love for twitter with your love for the shell with Twyt. Find out how by visiting linux-mag.com.

Linus Torvalds Loves His New Google Nexus One
Monday, February 08, 2010 @ 19:55:26 CET by tw45admin (45 reads)
GoogleSelf-described cellphone cynic and "father of Linux" Linus Torvalds decided to get a Google Nexus One the other day. And while the customer service lines may be clogged over the phone's performance, Daddy Linux is positively pleased as punch. Unsurprisingly, the man who invented the most popular open source operating system in the world is a "happy camper" over the fact that this cellphone runs Linux. But Linux alone wasn't enough to get Linus on board with the rest of the smartphone crazy 21rst century, no sir. His previous phones, in fact—the ones he mostly used to "play Galaga" on long flights—also had various versions of Linux, but lacked that certain spark.

Recover from a frozen system with the magic SysRq key
Monday, February 08, 2010 @ 13:55:32 CET by tw45admin (45 reads)
HOWTOs and similar articlesThe magic SysRq key is a key combination understood by the Linux kernel, which allows the user to perform various low level commands regardless of the system's state. It is often used to recover from freezes, or to reboot a computer without corrupting the filesystem. If you see that using Ctrl+Alt+Backspace does nothing, then is the time to use The magic SysRq key...
