Vor 45 Jahren protestierten Hunderte junge Menschen vor dem Opernhaus Zürich gegen die Kulturpolitik der Stadt. Die Opernhauskrawalle markierten den Beginn einer bewegten Zeit: Die Jugend forderte kulturelle Freiräume und Mitbestimmung.

In unserem Bestand finden Sie Literatur und Medien zur Zürcher Jugendbewegung und zur Protestkultur im Allgemeinen: Züri brännt oder Protest Cultures: A Companion.

@richlv @ojars @selea many LoRa mesh networks can co-exist, nobody is forced to switch. But the main enthusiasts in LV are now using a new firmware that works faster and more reliable - #MeshCore

Initiatives like @SafeguardingResearch work hard to rescue #researchData that are (about to be) deleted by the Trump administration, by using a Bittorrent network where many small nodes contribute.

This is a very #solarpunk way of doing science: community-driven, decentralized & resilient #SolarpunkScience.
Some tinker projects:

🎯1. Develop the most low-cost (in €, material resources, and CO2) p2p solution for data rescueing.

Maybe a #RaspberryPi + existing HDD? Reuse existing hardware. Compute costs in absolute and relative way (€ and CO2 per terabyte of data stored & shared). Is a bigger server plugged to a uni network more efficient in relative costs?

🎯2. Run a hackathon, help others to install the bittorrent clients on whatever machine they have.

🎯3 (Bonus): Build a purely solar powered, autonomous seeding node. E.g. the #LowTechMagazine went a long way in optimizing a web server that runs on solar + battery (achieving >95% uptime on a 50W solar setup)
https://solar.lowtechmagazine.com/2020/01/how-sustainable-is-a-solar-powered-website/

Imagine little autonomous, solar powered seeding nodes standing in gardens, tirelessly sharing research data whenever the sun is shining. A project that regenerates our digital commons in a sustainable, community-led way 🌱.

Please share your thoughts - is this a feasible and worthwhile project?

On "Vibe Coding"

The hype about the potentials (it’s always future potential, never real current use) of AI has discarded its last cycle (“reasoning models”/”deep research”, both terms being factually untrue and deeply deceiving at best) and moved to a new double whammy of “agentic AI” and “Vibe Coding”. Now “agentic AI” basically just means that some LLM […]

if it’s pure H2O I don’t think it’s safe to ingest either
Show threadEk-Hou-Van-BraaiMay 25
Why? How much would be safe
Show threadEddyzhMay 25
It’s difficult to say and drinking a bit of sweat with every sib would help a lot. The experiment is that some of your cells in a dish with excess of pure H2O will suck themselves full till they explode due to osmosis.
Show threadbrapMay 25
It’s lacking all sorts of minerals, electrolytes etc that the body needs. I doubt a glass of the stuff wouldn’t cause problems but if you only drink pure water then you’re going to start having problems pretty fast.
Show threadtakedaMay 25
It’s basically distilled water, no?
Show threadEk-Hou-Van-BraaiMay 25
Yea I think you're fine drinking like a litre of distilled water. Too much of anything will kill you, even regular water.
Show threadWazowskiMay 25
Your body must regulate ion levels - sodium, potassium, calcium, magnesium, etc. Drinking pure water in excess will force you to produce urine, and when you take a piss, you’ll lose some of those ions with it. Big, big problem. That’s why you need salt in your diet.
Show threadKlearMay 25
I think you’re just salty.
Show threadKorhakaMay 25
So if your diet is a bit high in salt, would distilled water help counteract it a bit?
Show threadLazhwardMay 25
Would you really? Food also contains minerals and electrolytes.
Show threadhappydoorsMay 25
You could certainly make up the electrolytes and minerals in other ways (drinking distilled water may even increase appetites for those types of foods). Still, drinking a liquid that leeches minerals out of the tissue around it isn’t healthy
Show threaddoortodeathMay 25
I think it has something to do about demineralisation, the water would absorb minerals out of the body
Show threadKornblumenratteMay 25
Depends on a lot of circumstances – weight, kidney and heart function, temperature, activity. The people I saw developing hyponatriema drank more than 4–5 l tap water. Desalinated water will cause problems sooner.
Show threadSundrayMay 25
The LD~50~ for pure H~2~O seems to be >90,000 mg/kg. (According to rat studies, so take it with a grain of salt.)
Show threadGurfaildMay 25
If you take it with a grain of salt it’s less toxic than pure water

@Ek-Hou-Van-Braai you joke but the Sigma-Aldrich safety data sheet for water has the following passage

Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.
