Virtualisation to reconcile GPL and non-GPL code

This guest whitepaper
explains how a hypervisor can be used to leverage GPL software while isolating it from proprietary code, in order to ensure compliance with the requirements of the GPL. It was written by a TRANGO Virtual Processors product manager, and uses that company's hypervisor as an example.

Reset the permissions of installed RPMs
Sometime by mistakes all file permissions get changed and you need to restore file permission. For example a shell script or some sort of corruption could change the permissions for packages (installed files), it may be necessary to reset them.

For example a long time ago my shell script run chmod and chown commands on /usr and changed the permission. Luckily rpm command can reset package permission. Sun Solaris pkg command and IBM can also reset permissions.

Redirecting traffic to another machine with Linux'
Nice idea.
"Let us suppose, as a not entirely hypothetical example, that you have added an A record for your subdomain name that points to one of your login servers, so that people can do 'ssh subdomain' and have it work. Let us further suppose that this login server is not your web server and you now want to make http://subdomain/ also do something useful, instead of giving connection refused errors."

Using multimedia keyboards with Linux
I know a lot of people have a keyboard that has features they don't use under linux.
"Lineak is a tool which aims at easy set up and configuration of multimedia keys on modern keyboards: these keyboards have additional keys which are usually not supported by Gnome or KDE since they are outside the usual keymaps. But lineak can handle such keys and can bind them to specific functions and actions."

Glick brings better standalone application bundles
Cool new package format.
"One such experiment is Glick, a runtime-less application bundle system for Linux. Glick allows developers to store an entire program and all of its associated data in a single self-contained ELF executable that can run without requiring installation or a runtime component. Glick can be used to package virtually any existing Linux application in this manner."

Securing SSH Using Denyhosts
SSH is a great way to remotely administer a server. However, it still has a number of issues when you open it up to the world. The server and client communications are secure but that doesn’t mean the hosts involved are. Opening an SSH service to the world allows for brute force attacks and means that the carbon interface is still the weakest link. Full Story

Linus Torvalds talks future of Linux
Nice interview.
"LT: Kernels may be hard, but partly because of that they are also interesting. I've always been more interested in "down to the hardware" details than in fluffy stuff like user interfaces etc, and an operating system kernel is about as down to the hardware as you can get without actually building it yourself (which I've also done - I was at a CPU company for seven years, after all).

Dtrace support for PHP
I gotta learn more about Dtrace.
"Dtrace is one of the coolest things in Solaris 10, adding great observability to applications. A Dtrace provider for PHP that adds probes to function entry and exit points has long been available. I finally got around to integrating this with the php in Cool Stack. "
