Tue 22 April at 9am UK, 10am Central European time, we will present probably the most popular webinar on MySQL Performance and Tuning.

We will have some real hands on examples with several tips and tricks - all that we can cover in an hour!

This is the agenda:
- Performance and Tuning Tools
- Query performance analysis and improvements
- Modelling tips
- Engine specific recommendations

Slashdot totally misinterpreted Jeremy's post about MySQL starting to build features first for their customers. As a business model , this sounds like a good way to get revenue , customers want certain features that are valuable to them , so why not let them pay for it .

The question however is how your development cycle works. Often this method of keeping code first for your paying customers , and when "the feature has been paid for" give it to the opensource community , is the wrong one.

What it comes down to is that you neglect the release early , release often and the peer review , many eyeballs see more bugs, fundamentals that made opensource projects big and stable. You are in effect stepping back to a proprietary model where you have to rush your deadlines because you have promised …

Getting data into more accessible formats is a big part of what we do at SnapLogic, so it’s always good to see someone else promoting simple over complicated. (Zen for us Python folks. )

A couple of weeks ago, Roger Costello posted a short article on Maximally Consumable Data, which triggered a discussion on the xml dev mailing list. Roger did a good job of distilling this down a a very digestable summary. Bill de hÒra summarized the same topic in a nice one-liner back in February.

At Mashup Camp 6 in March, I led an open space session on data services, under the title …

Remember yesterday? Well, I was reading that post again and realized that it's not entirely clear what Sun is actually doing with MySQL. Here's another article about the whole thing, MySQL Not Going Closed Source? that you can check out, but the gist of it is this:

MySQL Server is still (and always was) open source. The difference is not (as I might have implied yesterday) that the Enterprise product was going to be different. What's actually happening is that if you are an Enterprise customer (meaning, you're paying the big bucks for the Enterprise license), you get some extra "add-ons".

Somehow, calling them "add-ons" made a big difference (for me, anyway) in understanding what's going on: Sun is …

Wednesday night I attended a reception hosted by Sun and managed to win myself a Sun Fire X2100 M2 server!

Swag-wise, the conference was an improvement over last year, as judged by Laura Thomson’s T-Shirt index, with around a dozen shirts to be had.

Welcome to the 93th edition of Log Buffer, the weekly review of database blogs.

Conference season is upon us, so it’s been a busy week. There was the MySQL Conference & Expo, so let’s look at that.

Arjen Lentz posts about Sunday’s community dinner, including the arrival of an unexpected guest. Two photos: one of Pythian’s Paul Vallée getting some Sun; the second from the pre-conference dinner.

Zack Urlocker has a couple pieces with both photos and links to video of the keynote addresses from Marten …

While my involvement can generously be labeled as "minimal", the second edition of High Performance MySQL is slated to hit store shelves soon.

pre-order on Amazon.com

More info is available on O'Reilly.

Thanks to Baron, Peter, Vadim, and Arjen for picking up the torch to get a greatly expanded seconded edition done and out the door. There's a heck of a lot of new material in it.

(comments)

Its worth noting that all talks that have been blogged are being linked on the Forge Wiki. Take a look at Notes from the conference. There are some great entries there, and when the slides become live on the website (today, I believe), you can gather heaps of information, if you missed the most successful MySQL Conference & Expo. Book early for next year.

Thank you bloggers!

Pierre notes it is "only a matter of time before an open source company decides patents could be used to solidify open source dual-licensing schemes." I think he's right. In fact, I've seen this very issue rear its ugly head within my own company as I've thought through ways to partner with Microsoft and other proprietary companies.

It would be very easy to do as Novell did: Enter into an agreement to make a version of one's software "safe" from patents. It makes Microsoft happy. Presumably it makes one's users happy ("I'm safe from...my vendor and its partners?!").

But it doesn't fix the downstream problem, and it doesn't fix the broken software patent problem. It trades off FUD to make a sale. Myopic and ultimately damaging to one's customers, one's …

I've changed the ordering handling on the datagrid class so that it is now picked up from SQL query. From the examples hopefully you should be able to work it out. Simply, you specify the connection parameters and the SQL query, and then pass them to a Create() method. The ordering is picked up from the query string, defaulting to that which is specified in the query. You subsequently are returned a datagrid object. Much easier I think. I've not made it live yet, so you'll have to make do with looking at the development version. Barring any catastrophies though this is the code that will go live.
