Don't underestimate how often 'nation state operatives' who are a 'threat to national security' according to news and 'experts', turn out to be three bored teens in a bedroom

An hour of optimization later, and my algorithm for merging gappy sequences is *much* faster - for a testing set of 200k values (split up into a few separate slices and then re-merged into one), it went from several minutes runtime and 90MB heap use, to under 200ms runtime and 9MB heap use!

(This is for my Matrix client, for merging server responses into the local message cache)

I find this fascinating because it creates a sort of strange reversal of power dynamics; the thief is in control of the funds, and the operator, which may well be a wealthy corporation, typically has to publicly admit the hack, and ask and/or beg for the hacker to contact them to negotiate.

It's one of the few things about cryptocurrency that actually feel cyberpunk.

One of the few fascinating outcomes of the cryptocurrency world is the somewhat-established practice of "hack bounties", where someone hacks an insecure exchange or whatever, steals the funds, and then negotiates to return most-but-not-all of the funds in exchange for not being prosecuted, leaving them with a partial 'bounty' for having found the issue.

This negotiation process succeeds with impressive regularity.

This is an excerpt from the Hackaday article on the new (proprietary) Prusa printer:

"While the lack of design files for these new Prusa printers is unfortunate on a philosophical level, it’s hard to argue that they’re any less repairable, upgradable, or hackable than their predecessors."

This is not meant as a slight against Hackaday, since their point does make sense and I've left out the context. But I do want to draw attention to the phrasing for a moment: "it's hard to argue that..."

This is *exactly* how it works, how companies close up previously open systems. That it's hard to argue is *not* a good thing - instead, it's the crucial property that makes it possible to close things up in the first place.

If you have a reputation for open-source things, you're not going to suddenly close up everything, that would draw way too much attention and ire from the community. What you do instead, is to gradually close little bits, while assuring people that they can keep doing what they were doing.

You keep nominally offering them the *benefits* of open-source, or at least the appearance of those benefits, but without offering them the thing that *guarantees* those benefits. Then you start slowly chipping away at those benefits, only ever reducing the benefits for a small group without enough sway to speak out against it.

Sure, you still get the STLs, you can still print replacement parts! You can no longer modify the designs to create your own modified version, but hey, only a few people did that anyway, so what's the harm, right? Not like those few people can raise enough of a stink.

By segmenting the group of "people who are losing their benefits" into small enough chunks each time, you can eventually close down the entire thing, without ever pissing off enough people *at once* for it to be a risk to your business. Coordinating activist actions across years is very difficult, after all, so you just need to make sure that one group lost interest before pissing off the next one.

I cannot predict the future of Prusa, and it's possible that they end up being the exception to this process, but it's unlikely. Usually this is how it goes.

The moral of the story here is: if something is taken away from you, and it is "hard to argue" that it really harms you, that is *especially* the moment where you need to be paying attention, because it's often deliberate.
