prevent iris couch from sleeping

Iris Couch has a beautiful free couchdb service. The only thing is, that they’ll put it to sleep if it’s not used. And it needs quite a time until it’s backup again.

To prevent that I made a cron job on a server I have access to. A simple

curl -X GET http://DBNAME.iriscouch.com/_uuids

every 15 minutes prevents the shutdown of your couchdb. Maybe the interval can be bigger. I’ll have to test that.

The most Cthulhu-Burroughesque piece of movie I saw the last few years. Definitely on the more sarcastic side of Lovecraft and Burroughs.

our apartement is still gloomy, like the bottom of a lake, and we drift through the room silently, like eels. d,b.

ps3 eye camera microscopy

I built a microscope as shown to this tutorial. Building it was pretty easy. There is really no way to get rid of the glue at the optic’s base – believe me, I tried hard. Because I had no Dremel I ended up making the incision with a kitchen knife, which worked like a charm. In the process I opened the optics and ended up spilling the lenses all of the floor. Don’t do that.

The hard part was getting that camera run under OSX 10.8. The macam component didn’t want to run properly. And after some research I came across ofxMacamPs3Eye, which takes the part out of macam that you need to run the ps3 eye camera under osx. You don’t have to be a c++ champ to make an app. I just copy pasted all I needed and felt like is needed for a microscope application.

Here is the result, free and libre on github..

Life can’t be copied. At least not that easy.

The joke lies within printing this image. Most printers will fuck up and paint your piece of paper plain black. An interactive version of can be found here on the first page, try to print it (preferably use chrome).
