By the way, many of the talks in German should have a volunteer provided live translation to English (and vice versa, but for this event the c3lingo translation team focused their limited capacity on the deu -> eng direction), if you are watching on https://media.ccc.de/c/rc3 you can select the translated audio tracks via the cogwheel icon in the lower right corner of the video player.
I would also highly recommend
"Traue keinem Scan, den du nicht selbst gefälscht hast" [0] but I just noticed that there are no english subtitles available.
"In addition to exhaled CO2, people also emit small amounts
of other gases. [...] Activated charcoal filters are the primary method for removing these chemicals from the air."
I didn't downvote, but maybe because it is an insipid and disgusting question?
FWIIW in high altitude aviation where digestive gas could cause debilitating pain or even life threatening injury, the solution is to eat food that doesn't make you fart; usually steak and eggs. I'm sure the astronaut nutritionist types have this issue under control. People forget how many zillions of dollars went into the early space program to figure stuff like this out.
Even though it is a disgusting issue, it is a real issue, pretty much on topic.
And despite zillions of dollars wenting into it, if it would be just the smell, I believe it is possible someone just would have said, deal with it, there are bigger concerns in space, like keeping people alive.
(but charcoal filters work, like someone else pointed out)
And since you cannot really shower in space, I doubt the smell is the nicest up there.
A little gross, yes, but definitely not insipid. And yes, we assume that there's some solution (or that it's not a problem) somehow, but it's reasonable to be curious what the solution is.
This was one of this years best talks. I was a bit disappointed by the others mostly. Lots of streaming hickups and bad content.
I did like the Flutter UI talk, the baseband hacking talk by the girl, the horrible state of the Gesundheits IT, the Certified Voting SW (OK-Vote) in Bavaria (how stupid can they be?), and esp. the old UI demo "What have we lost"
Here are a few other talks I haven't watched yet, but certainly will because of the title alone:
* "Rage Against The Machine Learning"
* "Very Pwnable Network (VPN)"
* "RUN MSC"
* "Fuzzing the phone in the iPhone (aka D-d-d-di-di-d-d-di-d-di-d-di-d-dimm!)"
* "Fuzzers like LEGO"
* "I could not resist aka (Resists for Electron Beam Lithography )"
Here are a couple I might watch because of the people involved:
* "Conversation with Bruce Schneier"
* "Cory Doctorow: What the cyberoptimists got wrong - and what to do about it"
