Brief pause of that Sudoku series :  I’m working on my object-relational mapping framework code-named Eth.

It’s vaguely similar to Glorp but much simpler and not as intelligent as Glorp.  This time, the resurrection of my framework is more like… a rewrite from scratch.  It all started on VAST, then I ported it to Dolphin then Squeak and now Pharo.  Hopefully, now I will spend more time writing it than porting it! Also, it will exclusively support Pharo.  I also decided to write some SUnit tests to make sure I can properly handle PostgreSQL, MySQL and Interbase for the first version.  But I am also planning on supporting SQL Server, Oracle, DB2, Access and Firebird.  Eventually!

Besides, I’m also …

I’m back in the blogosphere!

This blog will focus on Smalltalk (mostly Pharo, Squeak, Dolphin, VAST and VW), databases (usually MySQL, PostgreSQL, SQL Server, DB2, InterBase and Firebird), algorithms and open source tools.  I’ll throw in some literature, music and mathematics occasionally.

Requirements to enjoy this blog : an interest in problem solving, a database and a Smalltalk environment!

OpenSQL Camp Portland 2009 is coming up on the 14th and 15th of November. Eric Day (of the Drizzle project) is the lead organiser this time around.

I went to the first edition in Charlottesville VA last year which was organised by Baron Schwartz (Percona). It was a great event, like other unconferences but with specific focus on database technologies. Monty (MySQL), Brian (Drizzle), Richard (SQLite), Jim (Interbase/Firebird/Falcon), Bruce (PostgreSQL) were all these, as were various storage engine builders. Very interesting, and lots of informal fun. If you’re anywhere near, do go!

Even though noone from our gang is able to make it to this one, Open Query is sponsoring this event – for all the above reasons. It rocks and deserves every support.

In record time, less than a week after the conference (thanks to the free Pinnacle Video Spin and YouTube), all 11 videos that were taken at OpenSQLCamp Europe are online.

For those who missed the sessions, or just want to relive the fun!

Almost all the sessions were filmed; regrettably Darren Cassar’s Securich – MySQL user administration and security made easy! and Stephane Combaudon’s Minimizing data access with covering indexes were not.

The YouTube videos have the descriptions and resources from the official conference pages, and links to pages. If there is more information to add (for example, the slides from a talk are now online), or if …

Welcome to the 151st edition of Log Buffer, the weekly review of database blogs. We’re going to take a fast tour through the best blogs from the week gone by, beginning this time, with Oracle.

Jonathan Lewis writes, “It occurred to me recently that I might be making casual use of terms that weren’t necessarily very well known to the less experienced user. So I’ve decided to build a glossary of terms – and I’ll try to add to it from time to time whenever I have a few minutes.”

Jonathan might want to add “Method R” to the glossary. Cary Millsap was making it understood, …

Welcome to the 145th edition of Log Buffer, the weekly review of database blogs.

MySQL

Since MySQL was surely the belle of the bloggers’ ball this week—why, everyone was talking—let’s begin with it.

Baron Schwartz started something with his post examining why MySQL might not benefit from having a mother ship. Dean Ellis of niflheim responded, arguing that everyone needs the MySQL mothership. And that got Sheeri’s Cabral’s attention—she took the middle path in her …

This is the 140th edition of Log Buffer, the weekly review of database blogs. Welcome.

Let us begin with Oracle this week. Dan Norris illustrates how to start database services automatically after instance startup. He says, “Services are an essential component for managing workload in a RAC environment. If you’re not defining any non-default services in your RAC database, you’re making a mistake.”

Vivek Sharma published his tale of, Latch: Row Cache Objects causing huge performance issue. Clever detective …

Welcome to the 117th edition of Log Buffer, the weekly review of database blogs.

For those of you who don’t know me, my name is Nicklas Westerlund, and I’m a MySQL DBA with The Pythian Group. This is my first time writing Log Buffer, and I hope I’ll do it right.

Let’s start off with SQL Server, where Simon Sabin asks if you know what concurrency is and how to improve it. And on SatisticsIO, Jason Massie focuses on the …

Welcome to the 116th edition of Log Buffer, the weekly review of database blogs.

This was the week of Oracle Open World (OOW), Oracle’s gigantic annual get-together in San Francisco — always the heaviest week in Oracle blogs, so let’s start there.

For day-by-day coverage of OOW on the ground, I recommend Doug’s Oracle Blog: OOW Day 1, OOW Day 1.5, OOW Day 2, …
