February 8th 2010: ZFS / btrfs / Petabytes on a budget

January 26th, 2010

The next WYLUG meeting is on Monday the 8th of February 2010 at Old Broadcasting House.

This month we have a talk from Tom Hall.

Tom will be giving an update to his ZFS talk of 2 years ago, recapping
that talk and introducing shiny new features that have appeared since. He will also look at btrfs and discuss why though the feature list is similar, underneath it is quite a different beast.

He will be announcing a new project to build the Storage Pods from a design released by Backblaze mid last year and a brief survey of clustered filesystems/high availability solutions to try and get robust file and block level storage on commodity hardware.

The talk will start at 7:00pm, but the room will be open for coffee, tea and chat from 6:30pm. Afterwards, we usually go to The Fenton pub, across the road from OBH, for more geeky chatter.

December 14th: Traditional Birthday and Xmas meal

December 3rd, 2009

This month’s meeting will be the traditional birthday and Christmas meal. WYLUG will be 12 years old this month, which makes it one of the longest established LUGs in the country.

For the last three years we have gone for a meal at the Spice Quarter (combination Chinese/Thai/Indian/Italian buffet restaurant). This has served us well and it seems like a good bet for this year too.

As in previous years, we’ll meet at the Victoria pub on Great George Street at 7:00pm and head over to the restaurant for 8:30pm.

July 13th: Matthew Bloch on virtualisation with KVM

July 7th, 2009

Everything you always wanted to know about virtualisation but were afraid to ask”. It’ll be a brief tour through the systems and networking concepts that a jobbing sysadmin ought to know before thinking about using virtualisation for the first time, and the software options available (though focussing on KVM).

Matthew Bloch is the Managing Director of Bytemark Hosting, a geeky UK hosting company specializing in Linux and virtualisation. His commercial software experience previous to Bytemark was in PC emulation and Java VM implementations, and he continues to work on systems-level code within the company, as well as supervising its day-to-day operations. As yet he has not achieved his ambition of becoming a rock-star games programmer.

Monday May 11th: Change of speaker, Smylers on “When MYSQL bites”

April 20th, 2009

Chris Street is unwell today so Smylers has agreed to bring forward his talk from next month to this month.

When MySQL Bites: Quirks to Watch Out For

MySQL is a very popular DBMS.  Or rather, it’s very widely used, which is not necessarily the same thing.  It has quite a few quirks, behaviour that many people wouldn’t expect and which if you aren’t aware of can be the cause of much frustration, pain, and data loss.

In the hope that more people being aware of these infelicities will reduce the damage they can do, a collection of them is presented here, along with tips and techniques for dealing with them.

There’s also an examination of why so often the MySQL feature is tantalizingly only available in one version higher than the one you’re running.

For those that dont know, Smylers was a founding member of Wylug, and after a period exiled to London returned to Leeds last year when he persuaded his employer to invent a position for him.  So he’s now Hosting Analyst for web hosting and domain names provider Webfusion — a job title so vague he
pretty much gets to make it up as he goes along.  Previously he was Head of Perl Training at GBdirect, where he taught Perl to Yahoo!, Microsoft, Sony, and the Nationwide building society among others, and was the lead developer for top UK IT news website ‘The Register’.

The meeting officially starts at 7:00pm, but the room will be open for coffee, tea and chat from 6:00pm. Afterwards, we usually go to the Victoria pub, behind the Town Hall, for more geeky chatter.
