if i can't hack it, it's not my application

For all interested, nerdfiles keeps disturbing the waves with new material every day!

You can listen to it at http://labbs.net:8080/nerdfiles.ogg

Or have a look at the archives here.

TBL, also know as Tim Berners-Lee, convinced his boss that to solve the communication problems of the CERN employees aroudn the world the solution would be a network of interconnected computers.

One human generation ago, ten computer generations ago…

Et voila, the www  was born:

Yay, let’s see how it goes with the rebel up! crew, in a great night with Maga Bo and MC Bnegão:

After his amazing live set at Rebel Up! 1,5 years ago, Maga Bo again comes to the OCCII to bring his superb live sound. And not alone this time, as he is bringing the Brazilian MC Bnegão with him as the vocal support in ragga ruff style, also straight from Rio de Janeiro!

Expect a feisty night filled with delicious organic beats and sweeping sounds. Think Brasil, Africa and western electronic influences in one big worldly mash, just as we like it at Rebel Up!

Having fun again with the Nun, Cake, Revolizer, and other VJs at a kinky party at the Stubnitz.

Join us to celebrate alternative porn filming!

RATED X
AMSTERDAM ALTERNATIVE EROTICA FILM FESTIVAL
15/16/17/18 JANUARY 2009
KRITERION AMSTERDAM (new location!)

The first Dutch film festival entirely dedicated to alternative, artistic and radical erotica, returns! Big-screen sexuality coming from a myriad of different angles and artistic perspectives, to celebrate a positive appreciation of the erotic in all of its richness and diversity.

Check out trailers and see live coverage of the festival on the RATED X TV.

The idea  with the Infopoint is to facilitate the daily tasks of a real group, without being intrusive or bureaucratic. It will not replace a group of people, but it will help to organize its work.

The infopoint is a live cd to install a NOC, a Network Operations Center, in a social space. Is linked to the physical space is built for, and to the people that makes the space run, or comes to it.

The Infopoint is a machine that runs on the local network and provides several network services like network shaping or web proxy, but also will help with calendaring, resources allocation, to do lists.

Why we want to make a new application? There are several applications on the open source business side of things to handle schedules/resource allocation. But all of them are based on a hierarchical, business mind. We would like to develop a tool to help other forms of more empathic or also changing organizations, where people comes to collaborate once a week but is not there every day, for example.

On the resources allocation, somebody could come to the desk where there is a person doing the shift of that evening and say: “I want to give a workshop about something the day 15 and I need a projector and also I would like to record the talk”. All this information can be put in the machine, and the projector and the room will be reserved for that talk.

Other person can see there’s a task to be done, but cannot do it. This task can go to a task pool, so everybody on the group knows about it.

Is important to notice how much time people that works on production – management of a cultural space spends on the phone and repeating things. Specially in non-professional environments.

I use liquidsoap on several machines as a playlist engine for streaming archived material.

But many times the connection or the bufffer will fail, and the stream needs to be restarted.

For that I asked jaromil to help me out with a little shell script that checks each two minutes if the stream is on the server. In the case the stream gives a 404, the machine restarts the liquidsoap system, and the stream is online again!

In the server, for security reasons, the liquidsoap has its own user.

So I want to have a small  script I can run on the crontab for that user:

liquidsoap@labbs:~$ crontab -l
# m h  dom mon dow   command
#radio hackmeeting
*/2 * * * * /usr/share/radio/checkstatus/icecheck.sh   > /dev/null &

This is the script:

#!/bin/bash

mount=http://giss.tv:8000/hackmeeting.ogg

cd /usr/share/radio/checkstatus/

rm res

lynx -dump -error_file=res ${mount}  > /dev/null &

sleep 1

killall lynx

result=`cat res | awk '/STATUS/ {print $2}'`

# if stream not running, restart it
if [ "$result" = "404" ]; then
        killall -9 liquidsoap
        echo "hackmeeting streaming restarted" >> /home/liquidsoap/liquidsoap-hm.log
        cd /home/liquidsoap
        /usr/local/bin/liquidsoap scripts/nerdfiles-hackmeeting.liq &
fi

cd -

Now the computer will check each 2 minutres for the stream…. and I will not find the radio down anymore!

Desde que terminó el Hackmeeting este año se formó en la Casa Invisible un grupo de radio.

Si se sigue el impulso terminará haciendo radio por las ondas, ya que hay un transistor que necesita un par de arreglos. Por ahora estamos poniendo en funcionamiento la infraestructura de producción y almacenamiento de audios.

Los técnicos invisibles están montando el estudio, con una mesa reciclada que hubo que arreglar y micros y mate.

Un grupo heterogéneo se está constituyendo como productor de contenidos, para grabar y propiciar el espacio en el que otras personas a su vez puedan dejar contenidos.

A mí me toca estar en el grupo que dará la infraestructura informática. Pero como dice el Jaro, MAI PAURA, miedo nunca, y además cuento con la ayuda de los tres carlos! el moro, el san juan, el wifi.

Estamos montando un sistema de continuidad con el Liquidsoap, que se almacena en dos sitios: En el servidor de red local de la Casa Invisible y en Labbs.net, que una vez más echa un cable en un proyecto de streaming….

Además necesitamos una interfaz para que los productores de audio puedan agregar archivos a la continuidad, enriqueciendo y agrandando el archivo. Esta interfaz de momento la resolveremos con un servicio ftp que resulta fácil de usar para nuestros mediactivistas.

Al mismo tiempo, preparamos el estudio de la radio para poder encodear material, tanto el producido ahí como otros materiales. Hay una red SAMBA que ayuda a repartir el material en local cuando estamos en la Casa Invisible, y que al mismo tiempo sirve de backup y cache del servicio online. Este estudio también puede hacer programas en vivo, para lo que estamos preparando una máquina.

En el servidor, el liquidsoap estará chequeando un punto de montaje específico (provocando, a decir verdad, un poco de spam en los logs del icecast…) y en el momento en que este punto de montaje esté activo, el liquidsoap lo pondrá en lugar de la continuidad. De este modo podemos tener una sola dirección de streaming, y cuando tenemos un streaming live el liquidsoap lo emitirá.

Ahora lo que gustaría es tener todo esto empaquetado de alguna manera…

Thursday 6 and 13 of November

Pure Data is a graphical programming environment to manipulate audio and video in real time.

Is Open Source and works in all platforms, but we are going to see some libraries that work mainly in Linux… so take your ubuntu with you!
