Technology@lemmy.world•Anybody Who Thinks Orbital Data Centers are a Good Idea Is Suffering from AI Psychosis, Experts ArgueEnglish
61·20 days agoWell, you can’t really come up with a novel material to dissipate faster because the math I presented is actually assuming perfect efficiency. If you understood the math you would have noticed the physical constant governing that process. I never came up with any arguments against it, I am just stating a fact that it would take a 100 megawatt data center a 250k ish square meters of radiating surface.
I am against data centers in space for more practical reasons though, space isn’t a good environment to really build anything and we are decades or centuries away from doing anything like it. The data transfer won’t be ideal via microwave transmissions for many of the things you are going to want to use the data centers for. Getting the material itself to space is far fetched and manufacturing in space requires an entire earth bound supply chain and adding the step of launching into space isn’t going to be cost effective at any scale.
Data centers they should be smaller, distributed and hooked up to the L3 fiberoptics network and instead of subsidizing mega corporations we should be educating and empowering people to self host hardware they own and control in their own home to build a distributed cloud. I don’t care about data centers in and of themselves or where they are. I care that the capitalist governments are going to squander the capital build out for things I don’t like such as surveillance, military industrial tech and bull shit. Since they operate as a get rich quarterly scheme and not a long term asset for man kind, the build outs are going to be where the land use is cheapest and those all happen to be sensitive ecosystems facing other challenges already, otherwise they’d be desirable and expensive.

10·20 days agoYou just need something like ~256,000 m² or like 60% the size of vatican city of radiators to dissipate 1mw power at 300k, I calculated it https://crazypeople.online/post/20952535/9448375

141·21 days agoSounds reasonable for me to cancel Mullvad and tell everyone else to cancel. I don’t care if that piece of shit white supremacist Nazi did it as a personal choice or as part of the company. He is my enemy, I am at war with him and I will not do anything to support him. Hopefully enough people stand up so they put him out on his ass and he loses everything which is less than Nazi’s deserve.

Technology@lemmy.world•SpaceX Stock Plunge Wipes Out $600 Billion After Cursor Deal Spooks InvestorsEnglish
2·1 month ago800K is 526C! You can’t run a datacenter at that.
Yeah, the temperature was an estimate for the nuclear reactor that would be needed lol, I tried to explain that most of the datacenter would be closer to room temperature which would require absurd sizes of radiators

Technology@lemmy.world•SpaceX Stock Plunge Wipes Out $600 Billion After Cursor Deal Spooks InvestorsEnglish
3·1 month agoYeah, maybe not impossible, but I mean extremely unlikely. I found a thread on reddit that had examples and a spreadsheet https://www.reddit.com/r/IsaacArthur/comments/11kp7s4/how_large_of_a_heatradiator_would_a_spacecraft/
To run a data center in space you would need some kind of reactor producing around 100 MW. If rejecting 100 MW at 800 K
A= 100,000,000 / 0.85×5.670374419e−8×800
The number is the Stefan-Boltzmann constant (σ) https://physics.knox.edu/OnlineHW/zTest-PhysicalConstants.html
A≈5,065 m²
So roughly:
5,100 m² of radiating surface
That is a square about:
√(5065) ≈71 m per side
If it is a double-sided radiator panel, the physical panel area could be about half:
2,530 m² of panel, about 50 m × 50 m, assuming both sides radiate effectively.
Also temperature matters enormously so
At emissivity 0.85:
Radiator temp Area for 100 MW 300 K ~256,000 m² 500 K ~33,200 m² 800 K ~5,100 m² So the answer is about 5,000 m² (lol this is like “a football field” on each side) at 800 K, but balloons to absurd levels like hundreds of thousands of m² if you are trying to dump room-temperature waste heat which there would be a significant amount of. That is for a single small data center at current power needs. In the US alone data centers use 176 TWh (https://www.congress.gov/crs-product/R48646), so there is no chance we are going to be migrating a significant portion of it into space.

12·1 month agoMy favorite part about data centers in space is it may actually be impossible from a physics standpoint to build the heat radiators large enough for even a small one. Even though space is cold and would seem to make sense, it is also a destructive vacuum and to radiate even a small amount of heat outside of a shielded core would take a huge array of radiators

Asklemmy@lemmy.ml•According to Lemmy Users: Blockchain was a grift, AI is a grift, Quantum computing will be a future grift. So according to you what new and emergent technologies are not / will not be a grift?English
221·1 month agoCalling blockchain a pure grift ignores the serious enterprise-level work being done to solve real logistical problems. The technology behind NFTs isn’t just for JPEGs it’s used to create a unique and immutable digital identity for stuff like physical shipping containers and pallets as digital twins. In a global supply chain where a single shipment passes through dozens of untrusted parties like factories, freight forwarders, ports, customs, and warehouses a distributed blockchain ledger provides a single source of truth that replaces manual emails, scanned paper documents, and spreadsheets. Smart contracts can automate releases upon verified scans, directly reducing the demurrage and detention fees that cost millions of dollars. The big hurdle isn’t that the tech doesn’t work or is a grift, it’s getting competing companies to agree on common standards and invest in the infrastructure. The speculation was a sideshow, but the underlying utility for tracking physical assets across trust boundaries is a real thing

Technology@lemmy.world•Women in Brussels 'filmed without their knowledge' by men wearing Meta smart glassesEnglish
3·2 months agoIf the company puts up a sign notifying that there are cameras on the premises then under Article 6.1(f) https://gdpr-info.eu/art-6-gdpr/ it is allowed due to “legitimate interest” in deterring crime, securing premises, promoting general safety. This could be argued in a court that it fails the balancing test and that they could and should use more narrow means of collection but the way the courts have ruled I don’t think you’d win that case. Although to be fair the EU doesn’t use common law or case law for decisions so it could be up to the particular judge.
Going back to the article though, if a person with the glasses is filming for “purely personal or household activity,” the entire GDPR is exempt under Article 2(2)© https://gdpr-info.eu/art-2-gdpr/
GDPR regulates the data and the processing, not the act of filming or the expectation of privacy for an exempt usage. If they decide to sell this on a creeper site that is different but I wouldn’t look to GDPR to be the primary legal framework for this being explicitly illegal. The actions under original article would more directly be a violation of multiple other national laws like Germany’s “KunstURHG” and France’s “Droit à l’image”

Asklemmy@lemmy.ml•Is social interaction actually enjoyable or just socially required?English
111·2 months agoSocial interaction is enjoyable and a requirement for a social species. The fact that so many people in this thread are depressed, dejected and lonely is really sad. Despair is not a sustainable life strategy. Please if you are unable to find joy in social interaction find a community you do enjoy and start to be a part of that because the alternative is withering and death.

US Americans, especially white US Americans, are incapable of doing anything because a violent revolution of their state is against their material interests and they know it. This is why settler US Americans are not part of the global proletariat. For the global proletariat violent revolution is a either a side step in material reality or a benefit but the settler US Americans, like Israelis, benefit materially from their state via subsidy and sharing in the global extraction from the empire.
