How to protect buggy programs from security vulnerabilities/buffer overflows under Linux and UNIX

A Buffer overflows is a serious security problem. It allows an attacker to inject executable code of their choice into an already-running application. This ability to run arbitrary code at certain memory addresses is dangerous as attacker being able to execute the instructions from anywhere in memory.
This howto explains use of DieHard software to protect popular application such as Mozilla firefox. It protects applications from as-yet unfixed bugs and security vulnerabilities that exploit them. Think of DieHard as a new line of defense against hackers, together with anti-virus protection and firewalls.

Happy New Year - What's Ahead?

Are you glad that New Year only occurs once a year? Who wants to look back and forward on the same day? It's inevitable, I suppose.Lately, I have reflected a lot on my Linux career in contrast to other IT work and environments. Linux started in 1997 for me and encompassed about nine years. I have looked back and have looked forward to the year ahead. I certainly have plans and hope you do also. But before looking ahead at our plans, we might examine our personal history to give ourselves a context in which to view a future with full knowledge that the best laid plans often go astray.

Xbox 360 closer to homebrew? PS3 exploited?

The title of this article touched on two questions that have caused a stir in the last few days. To begin, we'll take a look at a video that can be seen on YouTube that apparently shows an Xbox 360 exploited into running code (specifically a Linux coming soon message) while running Peter Jackson's King Kong. The video has got a mixed reception from the community; some believe it is real, some believe it is just another bluff.

KNOPPIX 5.1.0 Screenshots

Klaus Knopper has announced the release of KNOPPIX 5.1.0 live CD and DVD: "Finally, it's done. Just in the past couple of months, there has been quite a lot of new and exciting development in the GNU/Linux world, which of course should also be present in the current KNOPPIX version, even if some of the new and optional features (like the 3D desktop with Beryl) are still experimental. New kernel, KDE and OpenOffice.org releases have spoilt our planned release dates, but now all these are available in the new release. New: update to Debian Etch; Linux kernel 2.6.19.1 + FUSE 2.6.1; Cloop 2.05 real-time decompression; replace Unionfs with Aufs...." - DistroWatch.

Book Review: PHP and MySQL by Example

I always get a little nervous when I see the cover of a 912 page book on PHP and MySQL state 'The perfect introduction to PHP 5 and MySQL...no programming or database experience necessary!' On the one hand, you'd think that 912 pages would be ample space to teach the neophyte the nuts and bolts of server side web programming. On the other hand, I have trouble believing that I could hand this book to my father (who is a wonderful mechanic, carpenter and landscaper) who has no real computer skills and expect him to master PHP and MySQL. However, that's what a book review is for...to see where (and if) the rubber meets the road.

The Three Big Tech Battles of 2007: Who Has the Edge and What Is ...

I've concluded that just as PDAs (personal digital assistants) stand alone, MP3 players will be on their way out in 2007, replaced by phones that pick up this capability. This is one of the reasons Apple is expected to enter the phone space, and since it owns the MP3 space, it has an advantage coming in. Still, it is questionable whether music or messaging will drive the next wave.
