Maybe as you noticed twitter shutted down their jabber services for a long time. The reason is that you couldn't have your friends updates in your jabber client anymore. Couldn't you really? Wait! There's something you should possible know. ;-)

Today I invented a little gateway between the twitter API and the xmpp protocol. To speak with a jabber server you need a new account and you need sendxmpp. It's as easy as writing mails with sendmail. sendxmpp could read from stdin and send it then to your jabber address. There is only one little missing feature: You could only send messages or send something to a chatroom. For example in psi a new message window will popup everytime you'll get a message.
If you have a look into /usr/bin/sendxmpp it's a simple perl script. On line 301 there begins a message block where the message is formed to be send to your jabber account. You need only to add after to, subject and body a 'type' => "chat". Then everytime you'll got a message from your sendxmpp client you will see it in a normal chat window. That's really cool.

But how do we get the twitter updates for you? There exists a little script with the name bash loves twitter: blt. On the first run you tell him your account name and your password and then everything will run fine. If you run it multiple times you'll see the updates of your friends on your bash shell.

The last step for you is to build a loop or a cronjob so that blt asks twitter for updates and pipes it through sendxmpp to your jabber account regularly.
But keep in mind that it is only a unidirectional channel. :-/
To put updated to twitter via a jabber window, please use identi.ca or the laconi.ca software at all.

Thanks for your patient.

On our Freedom Not Fear weekend in Berlin we went to the c-base at night. There was a "after demo party". I've never been before at the c-base. It was recreative there.
There were DJs who played minimilastic vibes and people with their laptops who talked to each other and some other guys who only sitted down and relaxed.

The whole c-base as location is designed as a big space station. There were computers into the wall, blinking lights everywhere and you feel as part of this station.
It was really impressive.

Experiment in Color and Light

Today my girlfriend and I were in the exhibition "red. green. blue. Experiment in Color and Light". It is presented by our university.

The exhibition is about the history of the colors, how humankind produces colors naturally and synthetically, how we perceive colors and some practical parts. E.g. they've got parts where you can play with prisms and mirrors together with light.

All in all it's recommendable. :-)

hex.png Pixel Fuzzing

Some days ago I watched a talk of Dan Kaminsky about Pixel Fuzzing and the Bioinformatic Bindiff. It was a talk on the 23rd Chaos Communication Congress.

It's about how you can make hex data visible and how you will be able to remember them. That's a nice idea if your ssh doesn't tell you the fingerprint of another host but print it visually. It is possible when you turn on VisualHostKey yes in OpenSSH >=5.1.

Enjoy the talk. :-)

Freedom Not Fear

Last weekend I toke part in the demonstration Freedom Not Fear in Berlin. It was a huge demo of the AK Vorrat about freedom and against fears just because of surveillance (telecommunications data retention, eGK, closed-circuit television and wiretap operation).

It was a peaceful event all the time. Also the mainstream media reported.

We are all §129a!
