The kind folks at the PHP Usergroup Frankfurt invited me to talk about CouchDB. We meet on November 8th between 19:30 and 20:00 at the Brotfabrik in Frankfurt. If you are in the area and like to hear about CouchDB, feel free to join us.

I will be presenting CouchDB’s core concepts, its recent improvements and the programming interface to give you an overview. Building on that, I will explain how to architect CouchDB applications and show best practices for writing them not forgetting how to do all that from PHP.

In case you forgot:

CouchDB is designed for highly concurrent, distributed and fault tolerant systems. The core principles for scaling database applications are the foundation of CouchDB’s feature set. It supports on- and offline replication, data …

Google sometimes wears its source code on its sleeve (Summer of Code), and sometimes it doesn't, as when it was reported today that Google will be contributing significant source code to MySQL. Given how innovative and engineering-oriented Google is, it's hard to imagine a better vote of confidence in MySQL and a better code partner for MySQL.

Or a bigger reason for Oracle to worry about MySQL.

Earlier this year Google signed a Contributor License Agreement, which provides the legal framework under which MySQL can include code from another company in its database, MySQL co-founder and Vice President David Axmark said on Tuesday....

The search company has done a lot of work customizing MySQL to meet its special needs, which include better database replication, and tools to monitor a high volume of database instances, Axmark …

About a month ago, Network Appliance sued Sun to try to stop the competitive impact of ZFS on their business.

I can understand why they're upset - when Linux first came on the scene in Sun's core market, there were some here who responded the same way, asking "who can we sue?" But seeing the future, we didn't file an injunction to stop competition - instead, we joined the free software community and innovated.

One of the ways we innovated was to create a magical file system called ZFS - which enables expensive, proprietary storage to be replaced with commodity disks and general purpose servers. Customers save a ton of money - and administrators save a ton of time. The economic impact is staggering - and understandably threatening to Net App and other proprietary companies. As is all free innovation, at some level. …

During my career I've used seven source control management systems. RCS, CVS, Subversion, Bitkeeper, Mecurial, Continuous, and one other I have forgotten the name of.

To date I've lost code to all of them. One of them cost me an entire year's worth of work once (and refuse I to use it any longer for this reason, though I think the developers are fine people).

I believe there is an opportunity in the source control world today if someone looks beyond the proprietary nature of all of the tools built today.

What is the proprietary piece to these tools which I am alluding to?

It is the protocol. Each of these systems are tied as client and server.

I want a really good, robust, and feature rich server. I want web interfaces, I want the ability to search, and I want interoperability.

I don't really care if one developer likes subversion and another likes …

Today I was contacted by MySQL, they wanted to know If I mind when the MySQL category of my personal weblog would be added to Planet MySQL. Of course I didn't mind, so here I am...

OK, I am not getting too much people feedback on what would they like to hear about on MySQL Users Conference, so I went ahead and submitted few presentation ideas.

I do not expect all of them would be accepted, furthermore it would be hard to prepare so many good presentations if they are so please let me know if anything of this is of special interest for you. When I would be able to show that to organizers to help with decision.

Also let me know if you have submitted similar talk as in this case there may be way to work together to produce better talk instead.

Hidden Innodb Tuning Options Innodb Storage Engine has a lot of tuning options hardcoded as constants. We investigate if current values are truly optimal for modern systems and if you can get any …

About three months ago I announced ClickAider to become available to general public. And I think it is about the time to write about the progress we have with this project for those who interested.

The project generates decent interest and we have about 3000 sites Registered over this time, which I consider decent number especially as we did not do much of advertisement and PR keeping it low profile and working out few bugs which we might have.

We use GeoIP DNS based load balancing between "gathering" servers in Europe and US which seems to work very well both providing level of HA if one of the servers goes down and allowing to increase accuracy by reducing round trip. Over time we are planning to get more locations with pair of servers in each so we do not …

Cool, it appears I've been nominated for the 2007 Queensland Pearcey State Award - that's quite an honour!

The Pearcey Foundation takes its name from Dr Trevor Pearcey who in 1949 led the team that designed and built Australia?s first digital computer, CSIRAC, and which was in fact the world?s fourth digital computer ever to be built.

Now, coming from The Netherlands I lack a certain amount of education in terms of Australian ICT history, but I was at the Melbourne Museum the week before (for the AUUG 2007 conference), and actually visited CSIRAC which is (at least some parts) on display there. It features nifty technology like …

Perhaps I was a little quick to congratulate Neelie Kroes on a job well done forcing Microsoft to extend its interoperability protocols to open source software vendors and developers. It now appears that the terms of the agreement mean that it is incompatible with the GPL.

?I told Microsoft that it had to make interoperability information available to open source developers. Microsoft will now do so, with licensing terms that allow every recipient of the resulting software to copy, modify and redistribute it in accordance with the open source business model,” noted Kroes.

MySQL is listing a good overview of the bugs they still have open in 5.1
This list comes very handy as I have on my todolist to figure out which bugs they still have open in 5.1 Cluster to see if we are impacted by one or more of them.
Now I don't have to manually go trough the lists anymore ..

thnx MySQL !
