Solaris vs. Linux

This article compares suitability in large enterprise environments…

Quality of service requirements generally make difficult for specialists to work with more then two flavor on Unix simultaneously (two is probably optimal number of flavors of Unix that can be mastered by an average enterprise Unix administrator). In this respect in any large enterprise that already uses at least two flavors of Unix adding any additional flavor (not necessarily Red Hat of Suse, adding Solaris to AIX and HP-UX mix produced the same result) significantly stretches existing workforce. Such a stretch either deteriorates the quality of system management or creates the necessity to free people who will specialize in this particular Unix flavor; that may require adding to the administrators head count.

Open Source Linux Profilers

Profilers help pinpoint common performance problems in an application. This article compares and contrasts three commonly used open source profilers for Linux on POWER — OProfile, gprof, and tprof – which are available to end users and programmers for both SUSE and Red Hat Linux distributions.

Hide files with ext2hide

ext2hide is a proof-of-concept program that seeks to magically hide confidential data and files where nobody will look for them. It accomplishes its magic by making use of otherwise abandoned space in the superblocks in ext2/ext3 filesystems. Even though Jason McManus, the author of the code, has been testing and using ext2hide on his own machines without catastrophic results, I urge you to use the utmost caution both in testing and using it. If you don’t grok superblocks and filesystems, you probably should not experiment with ext2hide, at least until it’s out of beta testing. read more
