From time to time, I give talks on various topics. They are often in German, so it's not really interesting to list them on an English page. Sometimes they are rather trivial or about a topic that is only of limited interest, so I won't list them here, either.
There are however some talks that I'm somewhat proud of and that make sense to show to other people. A very limited selection is listed below. This is all work in progress. I will add more when I find the time.
STEAM-POWERED TELEGRAPHY: A LEAGUE OF TELEXTRAORDINARY GENTLEMEN PRESENT THE MARVEL OF TELEX ON THE NET - DRIVEN BY A STEAM ENGINE
A talk given with Ingo Schwitters, Sebastian Velke, and SkyTee at the 24th Chaos Communication Congress. Here's the original announcement:
We have built and modified a steam-powered Telex machine and connected it to the new-fangled invention for modern telegraphy known as "the Internet". We will present this steampunkish invention in form of a lecture, thus hoping to enlighten interested ladies and gentlemen on the principles of steam engine physics, 5-bit Baudot encoding, and historic telegraphy in general.
"The Magnetic Telegraph annihilates distance. So complete is this annihilation that the newspapers at Baltimore have made arrangements to report the proceedings of congress by telegraph, so as to have the intelligence from the capital (40 miles distant) as soon even as the Washington papers. A like effect will happen when the line is established between New York and Boston. The news from Europe brought by the Boston packet will be known in New York (220 miles distant) as soon as it is in Boston." -- Albany Argus, The Magnetic Telegraph, 1845.
Telegraphy truly holds the potential to connect the world, from the icy lands of Russian Alaska to the centres of modern progress in Manchester and London and the farest corners of Her Majesty's Empire in India or former colonies in America.
Over the last few months, a League of Telextraordinary Gentlemen at the Chaos Computer Club Cologne, after having acquired a historic Telex machine, have built a steampunkish modification of said machine, making it probably the first steam-powered telegraph connected to the new-fangled invention for modern telegraphy known as "the Internet".
Our technical spectacluar will include all our learnings about the basics of our apparatus:
While we plan to present this lecture in appropriate dressing (frock coats etc.), we do not plan to give the audience a special dress-code.
- steam engineering
- the history of telegraphy and Telex
- the Telex standard and its 5-bit Baudot encoding
- the embedded list of calculation for machines or "software" we used for making the Telex machine an RSS reader and a Jabber client
DUNGEONS AND HYPERLINKS: ELECTRONIC LITERATURE AND DIGITAL NARRATIVES FROM TEXT ADVENTURES TO HYPERTEXT
Given with Nika Bertram on August 8, 2007.
While there are interesting experiments in electronic literature, interactive fiction, and hypertext poetry, few are known to the mainstream. We'll have a look at different approaches, from the standpoint of literary criticism, a technical standpoint and from experiences in the literature market.
HACKERSPACE DESIGN PATTERNS
A presentation that I have given at several places over the last years, together with various other speakers. The content now lives on the Hackerspaces Wiki.
Here's a recording of a version done with Lars Weiler (Pylon) at 24C3, on December 27, 2007:
MONKEYS, TYPEWRITERS, AND THE MARKOV CHAIN REACTION
A talk on why machines should generate literature so humans don't have to. Held in Vienna, Austria, in November 2007. Part of the 2007 symposium "Ghost In The Machine" at Roboexotica 2007. Boingboing had a short writeup on it. They even showed my only slide with a typo on it!

ABOUT
Jens Ohlig is a software developer and digital citizen. He lives and works in Berlin and Bonn in Germany, but mostly on the Internet.
Enthusiastic about hacker politics and online activism, he co-authored a piece on how to build physical places for hackers which WIRED called “a collection of design patterns, or solutions to common problems [that] outlines some of the best practices used by German and Austrian hacker spaces”.
According to Wikipedia criteria he is irrelevant, but he believes he is in good company with that. His heart is a Turing machine.
