APC Opcode Cache
alan | 04 November, 2007 03:01
Armen recommended me to install APC opcode cache system to improve PHP performance on our servers. APC seems to be better for PHP5 and might be implemented as a default feature in PHP6. Pages are displayed faster and system load is better, but I shortly noticed that there is a common "White page of Death" problem with APC. This problem causes all pages to be displayed as a blank white page. Discarding cache contents (or simply restarting Apache) solves the problem.

Build Server for Parsix
alan | 22 October, 2007 01:35Finally I got some spare time to write an automated build server for Parsix GNU/Linux project. It checks a simple build queue, gets updated upstream source code, builds packages in a clean pbuilder chroot, straight from the local SVN working copy for i386 and amd64 architectures and then uploads packages to the APT repository. It is still very early version, but works. Have a bunch of ideas in mind and will add them one by one. The package watch system is also updated to support build server logs. Source is available here. It's a very time saving tool for a mad busy person like me, so I can spend much more time on other stuff instead of building packages manually like a stupid. Another benefit is that I can finally get some co-developers to help the project. Will post more information to the Parsix mailing list.

Practical English Usage
alan | 09 October, 2007 22:26
If you are an English language student or just learn it for fun, I may highly recommend Michael Swan's the "Practical English Usage" book. That's really a great and very well organized book. Quote: "Provides explanations and examples that are based on corpus research.
This work focuses on entries on 'Kinds of English', covering Standard
English and dialects, correctness, spoken and written English,
formality, and variation and change." You just can't ignore it. Get it from here. Despite it primarily covers British English, but also includes notes for American English speakers in needed cases too.
