I’ve been a VMware user for years now (even remember hacking disk files in order to trick MS Cluster Server into running on a couple of VMware machines). There are other approaches to virtualization, and other products which compete pretty directly with VMware, but VMware has always been the easiest to use and first to arrive with features which made my life as a software developer easier. So, you can imagine why I’m so excited that MySQL is part of the VMTN (VMware Technology Network).

This means that software is now being delivered inside virtual machines! In the MySQL version, you can download a VMware machine image with MySQL pre-installed into a SuSE environment from here. This is a huge step toward isolating application and OS instances from each other in order to deliver a much more …

/me hits the developer who made AutoSave ask if you want to save.

Honestly, what the fuck is up with that?

Chances are good that you are not the first person with your question/issue and that it has been answered/discussed in length already. Not doing your homework and asking a question which has been directly answered either in a product manual, this forum or the web, will reflect badly on you as laziness. As an added bonus, you can probably search for and find the answer in a couple of minutes as apposed to having to wait for someone to respond in hours.

Here are a few useful links to get you started-

To try and help in debugging, I’ve been playing with some of the extra tools that come with Valgrind.

Everybody knows that if you aren’t using Valgrind you are living in sin.

I’ve recently tried to have a go at using Helgrind. It’s suppossed to be able to help you in finding race conditions in multithreaded applications.

Well, mysql is multithreaded, and so is NDB (cluster), so, this could be rather useful (especially since, with some new work being done, i’ve found race conditions, i just need to find out where).

From the manual:

Basically what Helgrind does is to look for memory locations which are accessed by more than one thread. For each such location, Helgrind records which of the program’s …

I am no longer with MySQL, and will be starting my new job as a MySQL Guru at Yahoo! on December 6th. If you want the details about why or how or when, feel free to ask me! (My email is jeremy [at] jcole [dot] us.)

Wish me luck!

Update: See what Jeremy Zawodny has to say about it: Jeremy Cole will be Yahooing Soon too!

Update: Mike Hillyer chimes in: Jeremy Cole is a Yahoo!

Okay, here's my obligatory first post. I'll be rambling mostly about software here (because that's my 'day job'), and since my 'day job' consists of making sure MySQL plays nice with Java, you'll see some of that too.

From time to time, personal anecdotes will make it in here, if I feel so inclined.

This is kind of old news, but I wanted to put it in my blog anyway, as perhaps some of you haven’t seen it, and so I won’t lose it.

On June 15, 2004, LinuxWorld interviewed Jeremy Zawodny and Derek Balling regarding their new book, High Performance MySQL. They asked the following question:

LinuxWorld: You must have experienced lots of different databases of information over the years - what was your favorite use for a database system?

Jeremy Zawodny: That’s a tough one. I (Jeremy) really like the aviation database that Jeremy Cole …
