37c3: unlocked

This year I did not visit Chaos Communication Congress. But I was watching the streams an the released recordings of the talks. I really liked some talks, so I now share with you which talks I can highly recommend.

Highly recommended talks

The Extremely Large Telescope (ELT): Building the biggest optical telescope on earth


Von Zebrastreifen, offenen Daten und verschlossenen Verwaltungen: Luxemburgs kreative Route zur Amtstransparenz


Synthetic Sentience: Can Artificial Intelligence become conscious?


How to build a submarine and survive: Wie wir mit begrenzten Mitteln ein U-Boot gebaut haben und was ihr draus lernen könnt.


Reconstructing game footage from a Game Boy’s memory bus: The GB Interceptor


Recommended talks

Demoscene now and then: The demoscene is an underground computer art culture.


My comments

I found the talks this year pretty good. Operation Triangulation is really the total collapse of the illusion you can have a safe mobile device that is still connected to the internet. It is a shame that this was not yet detected for so many years that a Font-functionality in PDF could be an entry vector for hacking your iDevice.

The Synthetic Sentience talk impressed me and gave me quite some food for thought. What if we can simulate a brain on submolecular level in the future on quantum computers? How can future AI’s and Humans coexist in peace?

The Zebrastreifen talk reflects my observations that governments i.e. politicians usually don’t care at all about the normal life issues. This is actualy what you would wish for every city in germany to happen in regard to digitalization efforts. pretty cool work guys!

The submarine talk kind a blew my mind, but then I thought also, what it would take to replicate this experience and I came to the conclusion, that the presentation was as much a lifestyle choice presentation as it was an engineering venture with lots and lots of time spent – nevertheless very impressive. You find also some more bits abouu this guy here: https://chrismon.de/artikel/52739/selbst-gebautes-u-boot-aus-leipzig and this article on golem. I liked especially the thinking out of the box to just build a pool of water (sandbox) around the submarine for testing. Also the underwater communication solution is really a nice hacking venture to learn a lot about water.

The Game Boy talk by Sebastian Staacks (he has a blog) is a marvel of reverse engineering. You should watch it because it is also a picture perfect template how to present stuff where you need to film your gadget to show to people while you present. Sebastian recommends this talk from 33c3. I would also recommend the video of Sebastian explaining how to create a wooden Game Boy hull.

Short interruption: I maybe should buy one of these games next year. Would resemble a lot of the real thing as a game. But let’s see…

I liked the Hacking the Climate talk a lot, because it made one aspect very clear to me: the only entity which was actively compensating atmospheric carbon dioxide levels in the past in significant amounts is the ocean with a potential of 37000 GtC (Gigatons of Carbon) bound already.

The Toniebox talk demonstrated to me in an astonishing way, how a community and 4 people can not just replicate but also rebuild a product as an open solution. They actually even rebuilt their own cloud, so the hacker community here demonstrated that we can adopt services for gadgets which suffer from retired-cloud-obsolescence.

I was rather disappointed by the Demoscene talk because there was way to much talking, then the demos themselves were obscured most of the time by weird text messages and I had the impression the guy was just happy to revive his memories of Spreadpoint in public. I will therefore add a list of demos below this post which resemble really excellent demos from the Amiga times and will represent my experience of that time better.

More Amiga

Best of Amiga demo scene

Spaceballs – 9 Fingers – Amiga Demo (HD 50fps)
I loved especially the digitization of real video movements which was astonishing at that time. And I liked the really nice techno track and the stroboscope effect in lime green at the end. I highly recommend the making of.


Amiga demo Paranoimia crack intro 1989
This sound track just burned into my brain and heart. I love this song. It is minimalism in perfection. Thx paranoimia.


Unit A – Interceptor cracktro (amiga) 1988
This was kind of one of the most seen intro from me, because I was playing the Fighter Jet simulation game Interceptor a lot. No wonder I loved Top Gun as a movie too.


Amiga Demo – Crack intro by Quartex – 1996
Quartex was omnipresent in cracktros. I just remember their name.


Red Sector Inc – RSI Megademo – Amiga Demo (50 FPS)
Red Sector also had many trainers and cracktros. Usually in very fine quality.


Megademo (Budbrain, 1990, Amiga ECS) HQ
This was one of the famous megademos. Those were pure demo disks (on 3.5″ diskette) which just contained all the assets to run the demo. This one was impressive at that time.


Spaceballs – State of the Art – Amiga Demo (HD 50fps)
This was also one of those nice demo only contents in that time.


RED SECTOR (1990) Amiga Cracktro [ Letter Writer 2.0 ]


But I’d also recommend heavily the Amiga Cracktro Marathon:
Part 1Part 2Part 3Part 4

And this Cracktro Playlist.

37C3 in the media

Why do I blog this? I really wasn’t yet in the mood to visit 37c3 after my Camp 2023 experience. Geheimorganisation expressed that perfectly with „Mein Kopf ist leer“. I loved the talks being streamed, even though I know they only represent a tiny, tiny piece of the c3xp. I was pretty much irritated a lot being addressed with „Sie“ the formal way of addressing people by several talking heads (1, 2, …). Neverthelesse… big thx to the team that made the talks and relive and releases work so smoothly.

Windkraftanlagen: Kunst findet einen Weg

Ich bin kürzlich entlang der Autobahn A7 auf Höhe Dreieck Müllingen / Ingeln-Oesselse / Bledeln auf eine bemerkenswerte Installation gestossen. Ein Windrad ist ja an sich eigentlich nichts wirklich Besonderes mehr. Dieses allerdings zog meine Aufmerksamkeit auf sich – wie es bunte Lichter bei mir im Allgemeinen tun – da es buntes Licht aussendete.

Es wurde auch schon über dieses Windrad berichtet, aber nicht grade sonderlich viel muss man sagen. Daher sichere ich die Artikel darüber hier mal vorsorglich als Screenshot.

Die „Smarties“-Mühle Kunst & Windenergie

Update 3.4.2024

Ich konnte ein tolle Bild machen auf dem das Windrad beleuchtet ist.

Why do I blog this? Ich finde es eine äußerst gelungene Verzierung des Windrades und kann mir tausende weitere, unterschiedliche Umsetzungen anderer Kunst dieser Art vorstellen. Auch eine Windmühle als sophisticated Display fänd ich klasse, z.B. wenn man optisch die Luftverschmutzung, UV-STrahlung etc. schon auf hunderte Meter ablesen könnte wie auf einem Riesenbildschirm in Stabform. Sicher müsste man diese Kunst unter dem Aspekt der Betriebssicherheit und möglichst geringer „Lichtverschmutzung“ gestalten, aber dieses im Dunkeln so herrlich leuchtende Windrad war ein toller Anblick von der Autobahn aus.

blulamp: funny e-cigarette hacking

I had some fun tweaking my blu e-cigarette a little. It is actually quite nicely hackable. Those small plastic containers are actually assembled in a well defined way. You can easily disassemble them and clean them. Though you need to be careful to not use any force disassembling it.

Here you see, how I disassembled one empty smoked container (greetings to my lung here!). I carefully removed the top, black cap first, then worked my way down to the lower parts. To actually get all the not needed stuff out you need to pull out the bottom of the container.

As you see, I removed the small heating coil to actually solder the cables for the LED I wanted to power. Then I soldered the cables first to the LED I put through the black cap and put on top of the container. Then I soldered the cables to the contacts of the bottom of the container and closed the container.

And taddaaaaa… ready is blulamp a tiny flashlight build on top of the blu-container system. You should kinda remember which way you insert the final container to not swap plus and minus contacts for the LED accidentially. But now comes the funny part…

blulamp video in action

…it only lights up, if you blow and suck air through the USB-charging-port. LOL. Smoke your USB to create light, yeah, soooo cool!

Why do I blog this? I just thought, hey I carry a battery with me all the time, why can’t I use this as a flashlight at the same time? I still need to work on the power-on/off-switch though. Right now it is a safety feature which I fully grasp. But maybe I find an elegant way to occasionally bypass this safety net when I operate this thing in blulamp-mode.
