I’m in the process of moving some of my web systems to new servers. The blog.jj5.net has been completed, svn.jj5.net is a working progress, and some of www.jj5.net is broken until I can get around to fixing that too. This outage will manifest as some images which won’t load in blog posts. I’m sleepy now, so I’ll try and fix this tomorrow when I wake up.

blog.jj5.net
I’ve been meaning to make this change for a while now, and finally got around to it this evening.
I started blogging at blog.jj5.net back in November 2003 and continued through to May 2005. After that I stopped blogging for a while, but I started again at progclub.org in August 2011.
The ProgClub blog was imagined to be a group blog, my plan when I set it up was to have all the ProgClub members have an account on the blog, but that turned out to be a pretty poorly received idea. Eventually, and for a long time now, it has just been me (your host, jj5) over on the ProgClub blog.
Since this has become a personal blog, I figured it was time to move it from ProgClub back to blog.jj5.net, where it all began.
The transition should be seamless, old links should be properly redirected, old logins should continue to work, but if you run into any problems please let me know.
New look
After around 12 years with a completely unreadable look and feel I have finally bowed to pressure and switched my WordPress theme over to something sensible. I’m using the Twenty Eleven theme, which is what the old unreadable theme (known as OldSkool) was based on. This change is as a courtesy to my readers, who I do actually value. :)

Just preparing my lab cameras. This video is a bit sketchy because I made some mistakes during recording. But it is what it is. Hi! :)

Blowfish
I found myself reminiscing about my implementation of Blowfish today. It earned me the great honour of being listed on Bruce Schneier’s web page. My implementation made Blowfish compatible across 32-bit signed ints, 64-bit signed ints, and 64-bit floats. I wrote this code coming up on 12 years ago… how time flies.
