The latest from the MySQL community

1. ChipHacker -- collaborative FAQ site for electronics hacking. Based on the same StackExchange software as RedMonk's FOSS FAQ for open source software.
2. Democracy Live -- BBC launch searchable coverage of parliamentary discussion, using speech-to-text. One aspect we're particularly proud of is that we've managed to deliver good results for speech-to-text in Welsh, which, we're told, is unique. I think of this as the start of a They Work For You for video coverage. I'd love to be able to scale this to local government coverage, which is disappearing as local newspapers turn into …

Well, what a soft launch it has been.
Some people have asked:

When are you going to get a website? Errr…. Soon! We soft launched a bit early, due to some “leaking information” but figured heck, it’s open source let’s let it all out. Soon enough, I swear!

Where can I download DynamoDB? Errr… you can’t yet cause we haven’t finished our build/QA/certification process.

However, since DynamoDB is the alter ego business suit wearing brother of LucidDB, just download the 0.9.2 release if you want to get a sense of what DynamoDB is.

There are 3 built binaries (Linux 32, Linux 64, and Windows 32): http://sourceforge.net/projects/luciddb/files/luciddb/luciddb-0.9.2/ and you can find installation instructions …

For very personal reasons that don’t belong in this article, I decided a few weeks ago that it’s time for me to move on. The year and a half that I worked for Pythian have been a wonderful experience, and this is article is my tribute to this great company.

The MySQL Team

Being able to work side by side with two MySQL experts like Sheeri Cabral and Augusto Bott has been a great experience. I have learned a lot, not only about MySQL, but also about what a great DBA should be like. Both of them are recognized MySQL Community members and regular speakers at the MySQL Users Conference and other events. Sheeri has been named MySQL Community Member of the Year twice in a row. Both are a guarantee of excellent service.

My Predictions For Pythian

The two predominant forms of open source licenses are BSD and GPL. PostgreSQL is licensed under the BSD license , while MySQL is licensed under GPL . While the details are arcane, the business impact is significant, and that is what this post addresses.

The BSD (or BSD-style) License: This license basically says: ‘This code is provided as is, do what you want with it, and include this copyright in your resulting product.’

The GPL License: This license, also known as the copyleft license, essentially says: ‘This is free and distributed as source code, and any addition or extension must also be distributed under these exact terms.’

BSD essentially says I prefer open source code, so I’m making my source code open and freely available, but what …

Amazon’s SimpleDB isn’t a relational database, but it does provide elastic scalability and high-availability. Amazon’s recently announced Relational Database Services (RDS) is a relational database, but it doesn’t provide elastic scalability or high-availability. If you are deploying enterprise applications on the cloud (including Amazon Web Services), you might want to look at ScaleDB because it is a relational database and it does provide elastic scalability and high-availability.

Amazon describes SimpleDB by comparing it to a clustered database:

"A traditional, clustered relational database requires a sizable upfront capital outlay, is complex to design, and often requires extensive and repetitive database administration. Amazon SimpleDB is dramatically simpler, requiring no schema, automatically indexing your data and providing a simple API for storage and access. This approach eliminates the administrative burden of …

1. Toiling in the Data Mines -- Tom Armitage describes the process that Berg calls "material exploration". Programmers very rarely talk about what their work feels like to do, and that's a shame. Material explorations are something I've really only done since I've joined BERG, and both times have felt very similar - in that they were very, very different to writing production code for an understood product. They demand code to be used as a sculpting tool, rather than as an engineering material, and I wanted to explain the knock-on effects of that: not just in terms of what I do, and the kind of code that's appropriate for that, but also in terms of how I feel as I work on these explorations. Even if the section on the code itself feels foreign, I hope that the explanation of what it …

I can think of no better analogy than that of a multi leg race. You know, the races where one sprinter runs as fast as they can, before passing the baton to the next sprinter.

First it was Broadbase.
Second it was LucidEra.
Third it was Eigenbase / LucidEra / SQLstream (joint development w/ Eigenbase).

Having purchased commercial rights from LucidEra it’s ours to run with now, alongside Eigenbase and SQLstream.

After finishing my post about Monty Widenius's views on the Oracle acquisition of MySQL via Sun, I read that Richard Stallman (RMS) had published an open letter on the topic.

MySQL's ex-CEO Marten Mickos and MySQL co-founder Michael "Monty" Widenius recently released open letters to the EU. Marten supports the Oracle acquisition of MySQL, as part of the Sun deal. Monty urges the EU to block MySQL from being controlled by Oracle.
