Jeff Barr - Developer Chats in London
Jeff Barr, who we were lucky enough to have deliver an excellent and
entertaining talk a couple of months ago, is coming back through London
in July. This time he's interested in having some 1 to 1 chats with
developers using Amazons Webservices.
More details are on the Amazon Web Services Blog - Calling London blog post.

July and August Events
I'd originally planned to get to all of these, and even though I'm no
longer sure which ones I'll be able to attend I thought I should at
least mention them:
LUG Radio Live 2006 - Sat 22nd and Sun 23rd July 2006. Jono Bacon and one of the most talked about events from last year (which I'm gutted I missed). This is going to be excellent.
YAPC::Europe 2006 - Brummie Edition - 30th August to 1st September 2006. It's a YAPC, if you do Perl then you'll probably be here.
Exim Course 2006 - Tuesday 18th July to Friday 21th July 2006. This is being paid for by the company so it's the only one I know I'll be at :)
Linux 2006 - Thursday 29th June to Sunday 2nd July. When it comes to UK tech conferences few people have the experience and ability of Alasdair Kergon. It also has a free introductory track on the Saturday.
And a bonus one nighter in London:
Techa Kucha Night -
25th July, London. Steve Coast is one of those people that seems to have
discovered the 34 hour day, and he uses all of them up. This looks damn
interesting.

Apache ETags and Clustered Webservers
This one's as much for my own memory as for everyone else, I've already
used it at two companies and had to rediscover it at each...
If you have a number of load balanced apache servers serving the same site and you use ETags to help reduce the number of page requests make sure that the generated ETag doesn't consult the file inode; these will hardly ever be the same across servers - unless you build from a gold image - and will cause the client to download the page again each time it hits a different server.
And a bonus tip: make sure they use ntp and the clocks are synced, time differences make the ETag hashes differ.

Do You Work to Requests?
How much of your work is done based on a request? Does the task you're
working on have a an RT ticket, a Bugilla id or story ID associated with
it? If it doesn't should you be doing the work at all?
Even some of the more routine tasks can fit in this model, rather than remembering to check for the expiry dates of SSL certs or domain names have scripts that check and put any actions in to RT for you. You get an audit trail and a task list for (almost) free. You were going to write the checking scripts anyway. Right? Good.
I know this is overly optimistic but by thinking about it, and keeping track of how many changes you make that don't have an external driver your percentage should get better. And improvement is about all we can ask for.
