Gentlemen, Slap your Engines!

Once again, I was unable to attend all of the sessions I wanted to at this year's User Converence, but I was happy to make it to Bob Burgess' talk on bash scripting with mysql. The slides and examples aren't up yet, but when they are (which may be as you read this, check the last link), they would probably also be a great tutorial.


So, I got bore^D^D^D^D inspired later that day to put some of the practices into use, and worked up a script to run mysqlslap in various ways against a server, and then added a couple funcitons to try it out on each storage engine. The script is below in its entirety - bash scripters, please be kind in your comments. No, I didn't write all this just for the pun in the

DTrace in MySQL: Documentation and a MySQL University Session
+0 Vote Up -0Vote Down

DTrace has been something that I’ve been trying to get into the MySQL server for more than a year now.

After a combination of my own patches and working with Mikael Ronstrom and Alexey Kopytov we finally have a suite of probes in MySQL 6.0.8. Better still, after a short hiatus while I was busy working on a million-and-one other things, the documentation for those probes is now available: Tracing mysqld with DTrace.

The documentation is comparatively light and deep all at the same time. It’s lightweight from the perspective that I’ve added very little detail on the mechanics of DTrace itself, since there is no need to replicate the excellent guides that Sun already provide on the topic. At the same time, I’ve tried to provide at least one

2009: Waiting to Exhale
+0 Vote Up -0Vote Down

Lots of blogs list a bunch of stuff that happened in the year just past, and I have done a year-in-review post before, but in looking back at posts on this blog and elsewhere, what strikes me most is not the big achievements that took place in technology in 2008, but rather the questions that remain unanswered. So much got started in 2008 — I’m really excited to see what happens with it all in 2009!

Cloud Computing

Technically, the various utility or ‘cloud’ computing initiatives started prior to 2008, but in my observation, they gained more traction in 2008 than at any other time. At the beginning of 2008, I was using Amazon’s S3, and testing to expand into more wide use of EC2 during my time as Technology Director for AddThis.com (pre-buyout). I was also investigating tons of other technologies that take different approaches to

MythTV recover Lost+Found
+0 Vote Up -0Vote Down

My MythTV store lives on an LVM volume that is spread over 2 disks, one of them is an external USB disk. So the cleaninglady seems to have touched a cable and after coming back from holiday I had a read-only filesystem that afer a remount had about 350Gb in lost+found with irrelevant filenames.

    Open Source Technology US Conference Calendar
    +0 Vote Up -0Vote Down

    One of the best ways to keep up with your field and network at the same time is to attend conferences. It’s one of the things I look forward to every year. After learning that O’Reilly has decided to commit blasphemy and *not* hold OSCON in Portland, Oregon the same week as the Oregon Brewers Festival, I was inspired to look around at what other conferences I might attend in 2009. Turns out, this is a huge pain in the ass, because I can’t find a single, central place that lists all of the conferences I’m likely to be interested in.

    So… I created a public Google Calendar. It’s called “US Technical Conferences”. It needs more conferences, but I’ve listed the interesting ones I found. In order to keep the calendar from getting overwhelmingly crowded, I’ve decided that conferences on the list

    Stop Doing Things That Don’t Work (a.k.a: Excel and Virtual Private Servers are Evil)
    +0 Vote Up -0Vote Down

    Note that I’m talking about using these tools in some kind of professional way, and more specifically, I’m talking about using Excel as a database, and using VPS hosting to host “professional” web sites. By “professional”, I mean something other than your personal blog, picture gallery, or other relatively inconsequential site.

    Excel is not a database

    Here’s the thing: Excel isn’t a database. Most people who don’t work in IT don’t seem to understand this, and they’re deathly afraid to actually communicate with anyone in IT, so they take matters into their own hands, and create problems so big that IT is forced to get involved, because at some point this spreadsheet becomes “critical” to some business function. Then IT gets even more

    Generating Reports with Charts Using Python: ReportLab
    +0 Vote Up -0Vote Down

    I’ve been doing a little reporting project, and I’ve been searching around for quite some time for a good graphing and charting solution for general-purpose use. I had come across ReportLab before, but it just looked so huge and convoluted to me, given the simplicity of what I wanted at the time, that I moved on. This time was different.

    This time I needed a lot of the capabilities of ReportLab. I needed to generate PDFs (this is not a web-based project), I needed to generate charts, and I wanted the reports I was generating to contain various types of text objects in addition to the charts and such.

    I took the cliff-dive into the depths of the ReportLab documentation. I discovered three things:

  • There is quite a lot of documentation
  • ReportLab is quite a capable library
  • The documentation actually defies
