Seems incorrect; 10 "Numbers, Upper and Lowercase Letters" is 64^10 = 2^60, and with properly applied key stretching (a difficulty factor of 2^30, say), that's 2^90. To do 2^90 hash operations in 3 weeks would require to do almost 700 quintillion hash operations per second. Bitcoin hashrate is 7.983.858 terahashes per second, almost a hundred times lower. Hivesystems is proposing "a hacker" with a hundred times as much power as the entire Bitcoin network, assuming your PBKDF's difficulty factor is set to 2^30.

i'm a big proponent of forethought -- planning, design work, et cetera -- but planning work can only ever be done effectively by people who are also capable of executing the plan, and while delegation is important, when technical work is deeply entangled it's not possible to plan and delegate work that you yourself do not substantially understand. in other words, non-technical management of technical tasks does not serve to produce actionable planning; instead, it simply forms a reporting layer that produces 'performance data' (always, by definition, nonsense bullshit) to upper management that must be ignored and that relays 'guidelines' to developers (typically nonsense bullshit, but almost always necessary to ignore) from upper management. basically, it's a layer that sits between developers and middle management & spews random noise in both directions. a good developer can perform all of the tasks involved in bringing a project to fruition (including getting user feedback, managing the project, communicating with and delegating to other developers, writing documentation, doing UX analysis & design, and performing maintenance in response to changing requirements), but non-technical management's skillset is limited to interfacing with institutional tooling for creating the illusion of taylorization around the inherent chaos of any real work (ex., using JIRA, holding scrum rituals).

@oskay Oh, I wanted to say, except through-feed dies, a cylindrical or planetary thread rolling die has threads on it, so is itself a screw. Assumed by "trilobular thread rolling screw" you meant such a thread rolling die, so the question was how to make the die with limited equipment. Was puzzled at the idea of trying to make such a die by rolling!
In how much grinding and EDM, grinding is already common for hardened ballscrews (maybe forgot about ballscrews), and EDM tapping is already common, so clearly EDM is an option for making threads, though don't know of anyone using it for outside threads now. Obviously is not competitive for volume production.
Now see that meant https://taptite.com/assets/files/taptiteii-conti-reminc_5.pdf the which is a self-"tapping" machine screw with a non-circular cross-section. ("TRILOBULAR" is a trademark.) Seems like rare geometry is principal problem, together with surface finish.
The REMINC brochure emphasizes the need to request the brand name from distributors, so maybe are selling generic manufacturers clones of off-patent REMINC screws under different name. The brochure also gives geometry pretty detailed. Fascinating product, thanks.

@b0rk Many early computers used word sizes that were multiples of six bits, and used five or six bit character codes (predating ASCII and EBCDIC). 36 bits was common for big computers, 18 for medium, and 12 bits for small.

Are there ANY car manufacturers NOT selling data about you / your car?
Reading @pluralistic 's Feb 28 piece about VW tracking cars (and not providing the info unless you pay): https://pluralistic.net/2023/02/28/kinderwagen/

Is anyone keeping a list of car manufacturers who are NOT doing this?

How markets coopted free software’s most powerful weapon (LibrePlanet ‘18 Keynote) — Benj. Mako Hill
Talk is by @mako
Compared to 2018 we now have at least a little bit more software freedom for phones (for people that are willing to put the effort in to run with these options with practical downsides such as possibly not being able to run banking apps or not being able to use all the capabilities of the phone). We have options like: @replicant @mobian @Postmarketos @GrapheneOS @PINE64 Pinephone
Also any governing body that actually cares about humans should take a look at this campaign:

Your go compiler will automagically download different versions of itself within the next release or two.
That's a completely new level of insane normally only found in the JS ecosystem

@manniac So the way gossip protocols like scuttlebutt, nostr, earthstar, p2panda work is that they only show partial views of the network. So you're seeing that 5 people who use the default iris relay are following Jack. You can add more relays and you'll find there are many thousands of followers. It's different the way the fediverse is different from twitter.
