Saw this interesting paper about highly concurrent programming methods and figured the word should be spread! It’s not new material but it’s a good read. See the full article here: http://www.usenix.org/events/hotos03/tech/full_papers/vonbehren/vonbehren_html/

“Highly concurrent applications such as Internet servers and transaction processing databases present a number of challenges to application designers. First, handling large numbers of concurrent tasks requires the use of scalable data structures. Second, these systems typically operate near maximum capacity, which creates resource contention and high sensitivity to scheduling decisions; overload must be handled with care to avoid thrashing. Finally, race conditions and subtle corner cases are common, which makes

I’ve recently been migrating my wiki/documentation for Kontrollbase to Trac. For those that are not aware, Trac is a web-based documentation/wiki/Subversion tool that is used by countless number of software projects. Subversion, of course, is a software collaboration and code management repository that manages branches/tags/trunk files with revision control. It’s one of the most heavily used open-source code repositories available. Given that I use SVN (subversion) for all of my software applications and am now using Trac, the book “Managing Software Development with Trac and Subversion” by David J Murphy comes as a useful and great

This is a simple matter with a simple solution that might help someone save time and confusion. Emacs wasn’t coloring my comments correctly so I went ahead and had it change them to red-italic. If you are having similar issues you can drop the following into your home directory’s .emacs file. Enjoy. Keep in mind that if you are using emacs in a terminal session as opposed to the X-server gui then you will not see the italics.

Introduction

I don't know about you, but I can't imagine doing my PHP development without an IDE with a debugger anymore.

It autocompletes for me, it lets me step through each line of code, jumping around the project, execute and change the code flow on the fly, and does many other things that make me feel cozy, comfortable, and efficient at PHP development (as opposed to, say, CPP which makes me feel cold and lonely).

There are many PHP IDEs out there and I've tried most of them (including the free PHPEclipse and PDT for Eclipse) but kept coming back to NuSphere's PHPEd every time. The other ones

I’ve been using a lot of RESTful services these days and have been waiting for a good book that is dedicated to the topic. I recently received a copy of ‘RESTful PHP Web Services’, which does a successful job of outlining proven concepts in current web technology. If you want to learn the methods for creating and consuming RESTful services then you will find many examples in this book. From the architectural plans to well thought out code samples, the book covers a lot of ground in a relatively quick read.

The first chapter gives the reader a quick introduction to RESTful services and the most common PHP frameworks in use at the time of writing. I particularly enjoyed the section on the Zend framework due to

First of all, I'd like to thank everyone who read and gave their 2 cents about the [WordPress Plugin Development] How To Include CSS and JavaScript Conditionally And Only When Needed By The Posts post. The article was well received and will hopefully spark some optimizations around loading styles and scripts.

Here are some discussions and mentions around the web:

• an article on Weblog Tools Collection
• a forum post on WP Tavern

I’m really proud to announce the release of the version 1.0 of mysql-snmp.

What is mysql-snmp?

mysql-snmp is a mix between the excellent MySQL Cacti Templates and a Net-SNMP agent. The idea is that combining the power of the MySQL Cacti Templates and any SNMP based monitoring would unleash a powerful mysql monitoring system. Of course this project favorite monitoring system is OpenNMS.

mysql-snmp is shipped with the necessary OpenNMS configuration files, but any other SNMP monitoring software can be used (provided

The Problem

I've had MySQL on my Windows 7 laptop for a bit (as part of wampserver), mostly for local offline WordPress development.

However, even though MySQL is relatively stable, I've been observing a vast quantity of intermittent MySQL errors, as reported by WordPress in the PHP error log (C:\wamp\logs\php_error.log). Here are some examples:

[05-Jan-2010 09:47:51] WordPress database error Error on delete of
'C:\Windows\TEMP\#sql17e0_1a2_6.MYD' (Errcode: 13) for query SELECT t.*, tt.*
FROM wp_terms AS t INNER JOIN wp_term_taxonomy AS tt ON tt.term_id = t.term_id
INNER JOIN wp_term_relationships AS tr ON tr.term_taxonomy_id =
tt.term_taxonomy_id WHERE tt.taxonomy IN

One of the things that I am really happy about in MariaDB is that we have our releases available as apt (and yum for Centos) repositories. This is largely thanks to being able to build this on the OurDelta package build infrastructure (which again builds on things like the Debian packaging scripts for MySQL).

Something like the Debian apt-get package system (which is also used by Ubuntu) is one of the major innovations in the Free Software world in my opinion. Debian has spent many years refining this system to where it is today. Want to run the mysql client, but it isn't installed? Just try to run it on your local Ubuntu host:

    $ mysql
    The program 'mysql' can be found in the following packages:
     * mysql-client-5.0
     * mysql-client-5.1
    Try: sudo apt-get install <selected package>
    -bash: mysql:

Testing and automation. These two are key to ensuring high quality of software releases.

Ever since I worked briefly in the team at MySQL AB that is responsible for creating the binary (and source) packages of MySQL releases, I have had the vision of a fully automated release procedure. Whenever someone pushes a new commit to the release branch revision control tree, the continuous integration test framework should kick in and do all the steps needed for producing release packages:

• Checkout the new revision.
• Build a source tarball, and save it.
• For each platform, build a binary package from the source tarball. The build should be done in a freshly installed machine without any revision control checkouts, previous build trees, or extra installed software, to ensure that no unwanted

In the past few weeks I've been implementing advanced search at Plaxo, working quite closely with Solr enterprise search server. Today, I saw this relatively detailed comparison between Solr and its main competitor Sphinx (full credit goes to StackOverflow user mausch who had been using Solr for the past 2 years). For those still confused, Solr and Sphinx are similar to MySQL FULLTEXT search, or for those even more confused, think Google (yeah, this is a bit of a stretch, I know).

Similarities

• Both Solr and Sphinx satisfy all of your requirements. They're fast and designed to index and search large bodies of data efficiently.
• Both

Like so many others, I got interested in the Drizzle project when it started. Some good ideas, lots of enthusiasm, and just pure GPL license, no "yes, we will take your work for free and sell proprietary licenses to it" SCA.

I even started contributing some development, fixing a number of Valgrind-detected bugs in Drizzle. I am proud that we kept the MySQL code 100% free of Valgrind errors, and wanted to help keep the same in Drizzle. So I debugged and fixed quite a few of the Valgrind-detected bugs that had crept in since forking from MySQL.

As I remember, I got down to two or three remaining or so. However, I it did discourage me somewhat to see how quickly these bugs had been allowed to enter the code. I remember one case where there was a Drizzle patch that had tried to simplify some field types. As I remember, the patch tried to simplify the code by eliminating some of
