DrupalDownUnder 2012 will be held in Melbourne Australia 13-15 January. A great event, I’ve been to several of its predecessors. People there don’t care an awful lot for databases, but they do realise that sometimes it’s important to either learn more about it or talk to someone specialised in that field. And when discussing general [...]
This recent session at OSDC 2011 Canberra is based on part of an Open Query training day, and (due to time constraints) without much of the usual interactivity, exercises and further MySQL specific detail. People liked it anyway, which is nice! The info as presented is not MySQL specific, it provides general insight in how [...]
http://gigaom.com/cloud/lexisnexis-open-sources-code-for-hadoop-alternative/ HPCC Systems has released the open source code of its data-processing software that it’s positioning as a better version of Hadoop. The code is available on Github, and it marks the commencement of HPCC Systems’ quest to build a community of developers underneath Hadoop’s expansive shadow.

XKCD (as usual) makes a very good point – this time about password strength, and I reckon it’s something app developers need to consider urgently. Geeks can debate the exact amount of entropy, but that’s not really the issue: insisting on mixed upper/lower and/or non-alpha and/or numerical components to a user password does not really [...]
You take a look at someone’s MySQL (or MariaDB) data directory, and see mysql foo bar -> foo What’s the issue? Identify pattern. What does it mean? Consequences. Is there any way it can be safe and useful/usable? Describe. Good luck!
What’s the difference between INT(2) and INT(20) ? Not a lot. It’s about output formatting, which you’ll never encounter when talking with the server through an API (like you do from most app languages). The confusion stems from the fact that with CHAR(n) and VARCHAR(n), the (n) signifies the length or maximum length of that [...]
The linux.conf.au organisers have given all miniconfs an additional few weeks to spruik for more proposal submissions, huzzah! So if you didn’t submit a proposal because you weren’t sure whether you’d be able to attend LCA2010, you now have until October 23 to convince your boss to send you and get your proposal in.
Since you were going to linux.conf.au 2010 in Wellington, NZ anyway in January of next year, you should submit a proposal to speak at the data storage and retrieval miniconf. If you have something to say about storage hardware, file systems, raid, lvm, databases or anything else linux or open source and storage related, please [...]
The Daily WTF collects excellent tales from the real world. These days, the dismal dramatic sagas are often (at least in part) about mistakes involving databases; no surprise there, they’re so prolific… Anyway, if you can learn from other people’s mistakes, that’s cheap and efficient education! I thought I’d share today’s edition with you: it’s called [...]
