WordPress and plugin upgrade

After yesterday’s trouble, I just upgraded all my plugins.

Gengo’s URI renaming scheme with language code at the end was leading to an infinite redirect (adding fr+en/ to the URI) so I had to disable it. But doing so breaks the existing URI on your bookmarks (if you had some) and on Google…
So I hacked gengo again so that if the URI ends with a language code, it is redirected to the basic URI.
A recent reading : Cool URIs don’t change is just about keeping the URI, here I’m redirecting, that’s not as good, but at least you wont get the 404 ;)

The link was on Peter Eisentraut’s Blog. I was reading his article about Remove and Purge. I was tempted to do the same, I even did for a few days. Then I read the comments, and ended using aptitude l~c view ;) . I was previously using synaptic only for purging residual configuration…

it’s been a while…

Well, I’m actually more reading than writing since I added Planet Debian to my feed aggregator gregarious.

Also did a few changes to the themes, updated wordpress without issue. Thanks to both wordpress and debian.

Finally this blog has electronics in the headline and I’ve never talked about it yet, but I’m practicing ;)

I’ve been looking for software to draw my schematics and keep track of my work, first for myself and when ready to post my work here.
One project that seamed interesting is Fritzing but it seams too unstable, I don’t mean that the software is unstable but the file formats are. That means that some project done with it today might not be readable by tomorrow’s version.

So I ended up using The gEDA project tools. Starting with gschem to draw the schematics and then adding PCB to prepare my boards.
I’m not actually doing real PCBs, I prefer using prototyping boards and soldering lots of small wires, but using PCB with a 100mil grid really helps for arranging the placement.

I started hacking with Atmel’s AVR microcontrollers using avr-gcc and avr-libc. I first build an USBtinyISP avr programmer. I’ll post the gschem and PCB file some day. (It can come sooner if you ask for it).

Almost forgot, I recovered an old bookmark on Chip Directory. It’s a pinout database of many old chip references including 74xx TTL series and 40xx MOS series.
