MySQL related IRC discussion channels
+0 Vote Up -0Vote Down

There are many MySQL related IRC discussion channels as the ecosystem itself grows. I join the following. Are there any that I’m missing?

Freenode (

  • #mysql – main channel for all kinds of end user MySQL related discussions (the noisiest of the lot, naturally)
  • #maria – main channel for all kinds of MariaDB related discussions
  • #webscalesql – for all kinds of WebScaleSQL discussions
  • #percona – main channel for all kinds of Percona related discussions
  • #tokutek – main channel for Tokutek discussions (TokuDB or TokuMX)
  • SkySQL-specific channels: #maxscale and #mariadb-mgr


  • #debian-mysql – for all kinds of Debian MySQL related bits (packaging, bugs, etc.)

Jeeze people. You’re all noisy. I’m sure it was all done for posterity’s sake.

Linus on Instantiation and Armadaification
+0 Vote Up -1Vote Down

I feel a sense of pride when I think that I was involved in the development and maintenance of what was probably the first piece of software accepted into Debian which then had and still has direct up-stream support from Microsoft. The world is a better place for having Microsoft in it. The first operating system I ever ran on an 08086-based CPU was MS-DOS 2.x. I remember how thrilled I was when we got to see how my friend’s 80286 system ran BBS software that would cause a modem to dial a local system and display the application as if it were running on a local machine. Totally sweet.

When we were living at 6162 NE Middle in the nine-eight 292, we got an 80386 which ran Doom. Yeah, the original one, not the fancy new one with the double barrel shotgun, but it would probably run that one, too.

IRC is the best support method and Open Source rules

I was working on a server today that was not hooked up to our usual monitoring systems for one reason or another and I needed to generate a database tuning report. Typically I use Matthew Montgomery’s ‘’ script for this since it’s command line based, simple to use, and generates a number of useful items for tuning recommendations. It’s a great starting point before delving into the deeper aspects of MySQL and the OS.

I ran into an issue with it on this server that was running the MySQL 5.0.77-percona-highperf-b13-log x86_64 build. The error was:
./ line 517: 5.000000: syntax error in expression (error token is ".000000")

There were three options to fix this issue

  • Dive into the code and modify it cowboy style
  • Use our typical monitoring against the client’s wishes

    It’s like removing the brakes from your car. yes, it will go faster (slightly less weight) but, dude, you just removed the brakes.

    Back in the day, I played video games on computers and not much else. My mom had recently bought a 386 for the family. When she was at the computer store, the clerk asked her if she had any kids. When she replied that she had four boys, he gave her a free copy of ID Software's Doom:

    One of my friends told me that this "Linx" thing is really great. That it is *much more* efficient than the windows 95 thing our cousin had gotten a beta release of.

    I also heard through the grapevine that Doom, the game that got me playing computer games, had been ported to this new operating system. I went to Barnes and Noble and looked through their books on "Linx" but couldn't find anything on the

    Description of MaxDB code tree
    +0 Vote Up -0Vote Down
    I had a conversation with Daniel Dittmar, one of the developers on the SAP team today. I am trying to get familiar with the MaxDB codebase, and it's difficult to do without at least a bit of explanation. The inline English documentation is written by native German speakers, so it's often difficult to discern. Having this map will help me quite a bit. I hope it helps some others as well.

    Thanks very much to Daniel for putting an evening in to documenting this.

    12:56 DanielD: can you point me to some docs on the maxdb source code?
    12:56 why are the different parts named with such short and
    difficult-to-remember names? :)
    12:57 partly, because if you work with them day in, day out, you
    remember them anyway and they are easier to type
