linux.conf.au 2011 CFP Open!
+2 Vote Up -0Vote Down

Head on over to http://lca2011.linux.org.au/ and check it out!

You’ve got until August 7th to put in a paper, miniconf, poster or tutorial.

Things I’d like to see come from my kinda world:

  • topics on running large numbers of machines
  • latest in large scale web infrastructure
  • latest going on in the IO space: (SSD, filesystems, SSD as L2 cache)
  • Applications of above technologies and what it means for application performance
  • Scalable and massive tcp daemons (i.e. Eric should come talk on scalestack)
  • exploration of pain points in current technologies and discussion on ways to fix them (from people really in the know)
  • A Hydra tutorial: starting with stock Ubuntu lucid, and exiting the tutorial with some analysis running on my project.

linux.conf.au 2009 wrap-up (incl Open Source Databases Mini-conf): Day 0-1
+0 Vote Up -0Vote Down

It’s no secret that I love linux.conf.au. My first was linux.conf.au 2003, in Perth and I’ve been to every one since (there are at least two people who’ve been to every single one, including CALU as it was called in 1999).

I’ve been on the board of Linux Australia for some insane proportion of the years since then (joining in 2003). Linux Australia is the not-for-profit community organisation that puts on linux.conf.au. It’s all volunteers and amazingly enough we have more than one group of people wanting to put on linux.conf.au each year!

This year, we Marched South to

MemberDB speed improvements
+0 Vote Up -0Vote Down

So I finally installed the xdebug PHP extension and started doing some performance analysis of MemberDB using xdebug and kcachegrind. The upshot of which is a number of commits to the bzr tree that dramatically improve performance in several key areas. The answer? Caching.

I’m not even talking using memcached or caching things in database tables or anything like that - just about everything is still the same dynamically produced content as before, but I’m now caching some simple things avoiding many round-trips to the database while executing a script.

There were a few things that were taking a fair bit of execution time:

  • The generation of the menu. In MemberDB, there’s a menu on the

    I’ve posted more there, check it out. Some from the recent MySQL UC, some from linux.conf.au, some from wherever.

    MemberDB - A Membership Database 0.4

    MemberDB - A Membership Database

    I released 0.4 today. A rather long awaited release. No doubt there’ll be bugs and the need for a 0.4.1 or something - but this is relatively bug free and has a bunch of new cool stuff to chew on.

    It’s also the first real release to support MySQL 5.0 (previous releases won’t work as MemberDB heavily uses views).

    must be time to use the OSDC conference registration/paper submission site

    it’s annoying. grr.

    but, on the other hand, I am speaking about MySQL 5.0 at OSDC.

    This is even cooler as 5.0 has gone GA. So it’s not “upcoming features” it’s the “here and now”.

    I’ll now have to release MemberDB 0.4 (the MySQL (http://www.mysql.com) release). Converting the Linux Australia installation over at some point soon too. The 0.4 tree fixes enough bugs that it’s worth it (one of which Pia found the other day).

    MemberDB election-results performance on new laptop
    +0 Vote Up -0Vote Down

    So I picked up my new laptop on friday. It’s an ASUS V6V - nice and fast, light, good resolution screen and lots of disk and RAM (it came with 1GB, I’ve got 2GB).

    Anyway, the transfer of data from my PowerBook went fine. I waited for xfsdump to dump /home from the powerbook to a firewire drive (and for “waiting” I do mean going out and seeing Charlie and the Chocolate Factory - which was very good).

    Installing Ubuntu on the ASUS went like a dream. Everything, and i do mean everything worked out-of-the-box with only one tweak. That was uncommented the ACPI sleep configuration option do-dad in /etc/default/acpi-something-foo to get suspend to ram working.

    The WEP didn’t work in the installer, so I initially just used the GigE adapter until the first reboot.

    The firewire drivers don’t really behave with this

    thoughts on the trademark and notes about slashdot being a big public wanking session (which is, if nothing else - quite accurrate and quite funny)
