mozz Admin , (edited ) in How much would hash digsets shortened if the whole alphabel was used

  1. It's a 160-bit hash, so using letters and numbers, it'd be log base (10+26) of 2^160, which is roughly 31. So 31 letters.
  2. Using upper and lower case, it'd be log base (10+26+26) of 2^160, or 27 letters.
  3. Don't use SHA-1; use SHA-256
  4. Upper and lower case to represent SHA-256 would be log base (10+26+26) of 2^256, 43 letters
  5. Internally, it's represented using 32 "letters" of 8 bits each, effectively using every possible ASCII character. The string representation is only of consequence when you're exchanging it over a medium where it needs to be robust and human-readable, and probably the benefit from squeezing it down to fewer characters for that representation is not worth the cost in terms of making it unclear how you've chosen to squeeze it and making life difficult for people who are trying to convert to and from the format. Hexadecimal is a little bigger but it's very clear and unambiguous what you've done, whereas using the full alphabet doesn't have that property.

Not the best article, but it's something

Censorship like this is one fast track to things like the French Revolution.

So basically it is up to you to inform yourself and make a concious decision which ai service you use. Like how you can use ecosia instead of google or host your webserice in norway instead of the american east coast (renewable energy instead of coal)

abbadon420 , in Chinese, Iranian, and Russian cyberattacks against water utilities across the U.S. becoming more frequent and more severe, officials say

How about other countries? There has been a cooking advice for my region for the past 5 days. It was lifted today, but a new cooking advice was issued for the region next to mine. The cooking advice says to boil your tap water for 3 minutes before drinking, because they found enterecococcen bacteria in the water.

Could this be a cyber attack? Like, there's not really a bacteria in the water, but the system is made to think there is.

0% surprised. This itself would be a fallback if they can't get the C4 in place in time, I'd expect. Unless it literally is just a small amount of C4 that's built in.

It's probably something easier to set up, like a couple of fuses in the package that, when a signal is applied to a particular set of pins, will blow and disable the chip.

CanadaPlus ,

It could be, that would certainly be safer. I don't think that sounds easier to set up than an explosive charge, though.

If it's not based on physical destruction, I'd guess it's some variant of a killer poke (so the thing is set to burn itself out or actuate parts into damaging configurations), combined with a thorough wipe of all software.

TSMC equipment only has the materials to function for about two weeks before needing a shipment of replacement parts for the fabs when they wear out.

CanadaPlus , (edited )

Yeah. Nothing lasts all that long when put next to 400,000 degree plasma. The bigger risk is just know-how that the Chinese could take advantage of, either by employing former staff or copying what they find.

Atramentous , in A Primer on Mastodon's New Board Members

Overall seems like a pretty balanced board. Al Shafei and Bezuidenhout have backgrounds aligned with the type of Mastodon I want to see. The lawyer guy dabbles in crypto law, but also did tons of pro bono work for Mastodon. Seems to me like he’s just passionate about emerging tech. Biz Stone is also an interesting inclusion. He’s obviously well connected to the VC space but has been pretty critical of Elon Twitter.

Yeh. I’m pretty comfortable with this broad mix.

Good thing I removed every Windows I had but one where I only game on lol.

I'm shocked I tell you! Shocked!

Jayjader , in New Windows AI feature records everything you’ve done on your PC

In light of the recent forays by AI projects/products into the reason of coding assistants, from copilot to Devin, this reads to me as a sign that they've finally accepted that you can't make an ai assistant that provides actual value from an LLM purely trained on text.

This is Microsoft copying Google's captcha homework. We trained their OCR for gBooks, we trained their image recognition on traffic lights and buses and so signs.

Now we get to train their ai assistant on how to click around a windows OS.

Great extensive write-up.

Stefan Hector, a representative of the Swedish Police Authority, said that “a society cannot accept that criminals today have a space to communicate safely in order to commit serious crimes.” A week later, it was revealed that the Swedish police had been infiltrated and were leaking information to criminals.

It doesn't matter because China will get to that level soon. They're progressing very rapidly through a booming research and espionage sector

DdCno1 ,

No, they are not. There are certain high technologies, especially litographic equipment, that China can not produce and can not catch up to, because it's a moving target and they will be perpetually lagging behind. The end result will be the exact same issue that Eastern Bloc computing suffered from during the Cold War.

Tolookah , in ASML and TSMC Can Remotely Disable Chip Machines If China Invades Taiwan

Seems simple enough to clear any calibrations/recipes, and it'll take years to get that back without the right tools/know how. Maybe pull the filters on the clean room on the way out the door, too, really burn that bridge.

Unfortunately though, there's always one guy in the office who knows how to get the machine running, even if it's a pile of smoldering charcoal, with a not-approved-by-IT USB drive that has backups of the weirdest stuff, from three updates ago.

But if China sees chip making as a state asset, I wonder if, knowing this, they may now be able to prevent it.

Hmm
