How To Set Up MySQL Database Replication With SSL Encryption On Debian Squeeze

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 though.

FOSS Hacker's Reverse-Engineering Has Skype Seething

Skype is hopping mad after a hacker reverse-engineered part of its code and posted the results on the Internet. Efim Bushmanov says he intends to make Skype open source, but company officials have implied he may be threatening the security of their product. It's unclear whether any legal action is in the works.

Will your next PC be running Android?

Recently, I predicted that the future of the PC may not be powered by the x86 processor architecture. With ARM chips assimilating everything from smartphones to cars, and companies like Nvidia working on high performance CPUs based on the ARM architecture, the assumption that x86 will continue to dominate the PC no longer looks iron-clad.

'Open-source,' privately-funded rocket lifts off

Copenhagen Suborbitals is a self-described Danish open-source, privately-funded, non-profit organization with a mission to launch humans into space. On Friday in a major test, it successfully launched a rocket and prototype spacecraft from a platform in the Baltic Sea to about 1.7 miles (2.8 kilometers) above the Earth.

Hone Your Desktop Clipboards with Parcellite on Linux

If you're a normal desktop Linux user, it has probably been while since you thought about the X Window System. Modern distros let you configure your video card without ever touching xorg.conf, and by and large the window managers and GUI toolkits just work without getting in your way. But there is still one lingering pain point: the clipboard. Between most user apps, cut, copy and paste work without a hitch, but terminals, text editors like Emacs and Vim, and a few other stragglers refuse to cooperate. If that sounds familiar, consider checking out Parcellite.

A Report From Beyond: Linux Sound & Music At Virginia Tech

From April 7 through 9 I attended Beyond, a series of lectures, workshops, and concerts promoted by the DISIS group at Virginia Tech - a.k.a. VTech - in Blacksburg VA. The festivities included presentations from Professor Brad Garton and Create Digital Music's Peter Kirn, plus some incidental ramblings from yours truly. The concerts featured performances by VTech's own Linux Laptop Orchestra, accompanied at times by percussionist extraordinaire Ron Coulter and a group from the Boys And Girls Club of Roanoke. Other performances included improvisations with some unique hardware controllers (more about those performances below) and original works composed by the participants.

A New Open-Source KMS Driver Just Published

Embedded GPUs on Linux are a big mess due to their lack of fully open-source drivers, memory management complications, and other technical issues. However, there is some good news to report today and that's on the emergence of a new open-source KMS driver.

Ubuntu Ensemble, Control for the Cloud

  • Groups: Ubuntu
An Ubuntu server engineer writes to tell us about a new innovative cloud technology "Ensemble" that the Ubuntu team has been working on. So What is Ensemble anyway? Ensemble simplifies the deployment, management, and scaling of services in the cloud. Developers, systems administrators, and DevOps practitioners can create, share, and modify Ensemble formulas to rapidly deploy their solutions in the cloud (and soon hardware!). What's interesting is that Ensemble manages the whole deployment on many servers as one big, well, ensemble! Excited about Cloud/Service orchestration already? Check the article for more details

Using and Understanding IPv6 on openSUSE 11

  • BeginLinux.com; By Andrew Mallett (Posted by aweber on Jun 7, 2011 6:05 PM EDT)
  • Story Type: Tutorial
So IPv6 has been around a while now but do we know any benefits? We may know that it is 128bits long and too difficult to type but if that is all then we do ourselves a little injustice in not knowing how easy IPv6 can make our lives. So let us take a look at some of the automation features of IPv6 including auto-address assignment, router discovery and why we do not need a broadcast address.

Analyst: Copyleft in decline

FOSS icon In a posting on the 451 Group's blog, Matthew Aslett presents an analysis that says there is a trend towards permissive, non-copyleft licensing. The topic has come to the fore since Oracle announced it was donating the OpenOffice.org source code to the Apache Software Foundation and relicensing it under the permissive Apache Software Licence 2.0. In the ensuing debate, the merits of permissive non-copyleft licences like the ASL 2.0 versus reciprocal copyleft licences like the GPL and LGPL came up. Aslett took the opportunity to gather some data.

Attachmate CEO: We Can Grow Legacy Novell Business

During a recent interview, Attachmate CEO Jeff Hawn said he was absolutely committed to the SUSE Linux business — which Attachmate acquired as part of the Novell buyout. But that’s not all. Hawn also described how Novell’s assets would be organized under Attachmate’s ownership. Plus, Hawn predicted Novell’s legacy business — which includes GroupWise and ZenWorks — can potentially return to growth. Here’s the update.

Researchers Challenge NAND Flash with Phase Change Memory

The PCM hardware is only half of the Moneta story though. The system's real value is contained in the software, which has been tuned for the higher performing PCM. Specifically, they developed a low-level block driver for Moneta that bypasses the Linux I/O scheduler, such that throughput and latency are optimized.
