This is the second article in a series of four articles each with a separate explanation of different quantum phenomena. Each article is a piece of a mosaic, so every one is needed to understand the final explanation of the quantum astronomy experiment we propose, possibly using the Allen Array Telescope and the narrow-band radio-wave detectors being build by the SETI Institute and the University of California, Berkeley.

Mike Wallner has thrown together some stats for the latest edition of the pecl/http package to test its response performance.   The results surprised me, because it clearly shows that the performance drop for starting the PHP engine and doing the neccessary negotiation to provide caching is not that bad.   There's a chart of the results as well as a full PDF with all of the stats the graph maps out. He includes the legend to make the graph easier to understand.

A technique originally designed to analyse DNA sequences is the latest weapon in the war against spam. An algorithm named Chung-Kwei (after a feng-shui talisman that protects the home against evil spirits) can catch nearly 97 per cent of spam.

Alchemi is a software framework that allows you to painlessly aggregate the computing power of networked machines into a virtual supercomputer (computational grid) and to develop applications to run on enterprise grids.      We are pleased to announce the release of version 1.0.6. The major changes since 1.0.5 are a LUA (Least Privileged User Account) operation for both Manager, Executor in normal and service mode and an option for executing user's GThreads in a secure sandbox (experimental)  Please note that this is a developer release intended for enthusiasts and early adopters as documentation is not up to date.

Joshua Eichorn has posted some slides that he presented at a local PHP User Group meeting just passed that serve as an introduction to PEAR.   I'm hoping to improve the slides a bit and give this presentation at lots of other places. If any PHP User groups on the west coast would like me to do a presentation about PEAR drop my a line.   To help further the cause of PEAR, he's also offering the slides in an archived file for presentation anywhere.

Michael Kimsal has come up with the start of a series to introduce PHP developers to the world of Grails (the Java framework).   The comparisons I plan to make will be mostly to PHP, cause that's what I'm most familiar with, though there may be some other comparisons from time to time.  This is a work in progress, but I'd be very interested in feedback from anyone out there interested in this aea - Grails, Groovy, PHP, why another language/platform/framework, etc.   The first two installments have been posted - part one and part two - with an introduction to what Grails is and a brief dip into some "Hello world" sort of code to give you an idea of the structure.

As you may recall from my last entry, I exchanged my cable box from a Scientific Atlanta 8000HD to a Scientific Atlanta 8300HD.  The latter, new box continues to output a signal from the cable connection even if I have it in HDTV mode.  It probably also continues to output AVI and S-Video.  This finally opened up a way for me to use my cable box with a MythTV box.   Thanks to a serious (and mysterious) spinal injury (I say mysterious because I haven't figured out how I did the damage), I can only work on the project for a half hour at a time, at most.  I have discovered some interesting things in those short segments.
