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.

I think "Draisy" is faster on the track and a much more realistic project. But "Monocab" is a University project, so it's ok for me that a few millions are invested there.

Looks like walking speed in their testing.

I know of a few security companies that use slack to work together that includes a shitton of privat data, source codes and confidentional information

Guess whoever introduced the company to slack service fucked up by not reading their policies.

Goddamn, I wish we could act like our own independent country for once instead of just puppeting whatever the US does.

Why is it always "pods"?

Poorly thought-out Facebook posts are forever; coverage of city council malfeasance from two years ago, not so much.

JUST PUT A FUCKING TRAIN ON IT WTF ARE WE DOING

androogee , (edited )

Read the article, that's literally the first thing they explain

It's very obviously a train if you just look at it. It's just a small train specifically designed for this purpose.

People are never fucking happy.

Trains are expensive to run if you don't have enough passengers (like in small villages).

The memory hole is real.

I think it's much more impressive that stuff that was added in 2018 and 2019 has a much higher probability of being deleted today than if it was added 2017...

Wonder if that has anything to do with covid and maybe new businesses models opened 2 years before failing and therefore websites of this companies disappeared.

Also I think it would be nice to see a graph of new websites being opened other the same time span.

millie ,

I mean, that kind of makes sense. A lot of small websites are probably for temporary projects, or may even be experiments. When the project ends, it usually makes financial sense to quit paying for hosting and domains.

Whole lotta small projects during COVID.

If the information was important wouldn't it already be passed around and expanded upon? The Internet is probably 99% junk, at least the posts I've made. Only the good stuff like goatse survives.

rar ,

Problem is, people rarely realize the importance until they're lost. Plenty of posts from 90s and 2000s containing valuable insights are probably lost forever. Remember that not everything online is in English, either.

Finding sources about Bush and Cheney fuckery from 2000-2008 is getting increasingly difficult. Their crimes are getting memory-holed.

EDIT: Specifically, does anyone else remember the specific act that Bush wanted to hit Quakers with terrorism charges over? I remember it being a bunch of Quakers in kayaks doing a blockade of a naval ship, preventing it from leaving port to go to Iraq. I can't find a fucking word on it anymore, and I can barely even find sources on Bush wanting to hit Quakers with terrorism charges other than some broken links at the ACLU. Quakers, as a reminder, are the only religious group in the USA that are default conscientious objectors because violence is 100% antithetical to their religion. These are the kind of people they wanted to use "terrorism" charges against.

This is like the disinvention of the printing press, at least from an archeological perspective.

Well, websites can still be made, so not quite the same, but I get what you mean:-).

And similarly, a ton of written material was lost e.g. when a library was burned - often unique or rare material subsequently lost in other ways, so very much the same process.

We need to watermark insert something into our watermark posts that watermark can be traced back to its origin watermark if the AI starts training watermark on it.
