Powers of Tau Operational Writeup

This is my report for my contribution to the Powers of Tau ceremony, which ended up not being included because of unknown corruption of the response.

GPG key transition

I am transitioning GPG keys from an old 2048-bit RSA key to a new 4096-bit RSA key.

I2P Android dev the fourth

The fourth development release (0.9.10-3_b4-API8) is out. This is a release candidate! I am working through the required-for-release TODO list so I can push these changes out in the official release builds, because the best way to find all the bugs and issues is to increase the

I2P Android dev the third

The third alpha release (0.9.8.1-27_b3-API8) is out. It took some time, but the results are good! Please test and report back :-) The main changes Graphs! * The stats to be graphed can be configured in settings. NetDB! * The stats page and the entry lists can be

I2P Android dev the second

The second alpha release (0.9.7.1-23_b2-API8) is out. I didn't expect to release a new build so quickly, but zzz and sponge pointed out that I had messed up the router control code when I migrated to Fragments. The router control code needs to be in every

Ignore request URLs in Jetty

I run a Seedless server (and if you have an I2P router with good uptimes, you should too), and it generates A LOT of log entries. I'm sure some people would be interested to know which routers are running a Seedless client or server, but for me it just takes

First post

Right, so I figure it would be useful to have some sort of blog here to keep track of the things I'm doing, so at least I don't forget them! Luckily, ikiwiki makes it rather trivial to include such a section, so here it is. Don't expect a weekly feature-length

A Linux version of Windows “alt codes”

One little feature on Windows that I’ve always liked is “alt codes” , where you hold down the Alt key and tap out a number and get a lovely little Unicode character appearing in your text. And it didn’t really make sense to me that the same thing wasn’

The joys of running your own server…

A bit over a month ago, the Slicehost VPS on which I ran this site (along with all my other services) decided to stop responding to requests. Pings were still going through but connections would just time out. Going into the web management interface, I discovered that something was causing

Hello world!

Having complained to myself about Google Sites for a long time, I have finally made the move to WordPress, which offers several benefits: * I host the site myself, and thus can do whatever I want with it. * It’s much nicer to use and much nicer to view. * Plugins! Lots
