At this point we have a 32-bit and a 64-bit Linux binary tarball, should work on most Ubuntu and CentOS and the like (I tested a few). Possibly OSX coming. Not sure on Windows right now. For further details and download links, see yesterday’s release post.
Antony and I are busy getting the Open Query GRAPH Engine code ready so you all can play with it, but we needed to test with a larger dataset to make sure all was fundamentally well with the system. We have some intersting suitable dataset sources, but the first we tried in ernest because it [...]
The favourite Open Query course modules as well as reworked and brand new ones, with November/December 2009 dates for Brisbane, Sydney, Canberra and Melbourne listed below. You can register for days/modules individually, to suit your time, budget and current needs. Your trainers are Sean, Ray and Arjen (see OQ people). For the Canberra and Melbourne [...]
This is a “dogfood” type story (see below for explanation of the term)… Open Query has ideas on resilient architecture which it teaches (training) and recommends (consulting, support) to clients and the general public (blog, conferences, user group talks). Like many other businesses, when we first started we set up our infrastructure quickly and on [...]
rsnapshot is a filesystem snapshot utility for making backups of local and remote systems, based on rsync. Rather than just doing a complete copy every time, it uses hardlinks to create incrementals (which are from a local perspective a full backup also). You can specify how long to keep old backups, and all the other [...]
We often need many tabs open in a browser, and horizontal tabs become unmanageable. Tab Kit allows you to have them vertically on the left, with various additional configuration choices. I opted for the tree structure, so when I open a tab from another one it’ll show up as a child to the original. I [...]
I was actually exploring inotify-tools for something else, but they can also be handy for seeing what goes on below a mysqld process. inotify hooks into the filesystem handlers, and sees which files are accessed. You can then set triggers, or just display a tally over a certain period. It has been a standard Linux [...]
Life as a Location Independent Professional can be hard at times, and very good at others!
Peter Lieverdink (also known as cafuego on IRC/identi.ca, engineer on OurDelta builds and for Open Query) has co-authored a book that’s available since Monday. The title is Pro Linux System Administration published by Apress. These days some people don’t want to bother with system administration, and either hire or outsource. Others want to find out more [...]
I’m happy to note (this is internal Open Query happiness but I’m pleased to share) that so far we have a 100% renewal rate for our Proactive Services for MySQL subscriptions. Some of the early clients have grown in the initial period and are have now moved to a higher # of hours (this can [...]
