I've been at PHP Conference over the weekend. (Work paid for me to go.)

Christ what a sausage-fest. ~700 attendees of whom maybe 12 were women.

Oh my!
That is seriously weird

Just installed the enlightenment window manager.

It is very shiny. Very shiny indeed.

[markfiend]

Gosh I've moved off enlightenment onto xmonad since then...

Anyhoo, I've been turning my Raspberry Pi into a jukebox with a web front-end accessible from my whole home network. Also ordered a set of blinkenlights for it.

Upgrading from Apache 2.2 to Apache 2.4 is a bloody pain that involves editing too many vhost files

Upgrading from Apache 2.2 to Apache 2.4 is a bloody pain that involves editing too many vhost files

Oh goody. I'm on 2.2.25-1 at the moment. Having said that...

Note: Even though Apache 2.4 was released over a year ago (Feb 2012), it still isn't available in the official repositories. You can however get it from the AUR as apache24.

I have bought myself a 3D printer.

Or more correctly, I have bought myself a heavy box full of parts that after much soldering, bolting, measuring, drilling, and swearing, will become a 3D printer.

Eventually it should look like this: http://www.reprappro.com/products/mono-mendel/

[lazarus corporation]

So, I last posted here in October. OK: geek report:

1. Launched new version of my website: http://www.lazaruscorporation.co.uk/ - for the geeks: PHP 5.5, ZF2, Doctrine 2, CSS media queries, and a fuckload (technical term) of RDFa

2. 3D printer still only half-assembled - will take a crack at it this weekend to try to get it finished

Mavericks broke my iMac

What happened?

[James Blast]

I d/l something dogey from the internets last Saturday and my machine ground to an halt. My optical drive's fecked so I couldn't use the systems discs that it came with to restore it, my only options was to go for Mavericks, now anytime I try to change anything it asks me for an Admin name and p/w. It doesn't recognise anything I input, so I'm stuck on Pacific Time.
