I enjoy things around information theory (and data compression), complexity theory (and cryptography), read hard scifi, currently work in infosec, am somewhat literal minded and have approximate knowledge of random things. I like when statements have truth values, and when things can be described simply (which is not exactly the same as shortly) and yet have interesting properties.
I live in the largest city of Switzerland (and yet have cow and sheep pastures and a swimmable lake within a few hundred meters of my place :)). I speak Polish, English, German, and can understand simple Swiss German and French.
If in doubt, please err on the side of being direct with me. I very much appreciate when people tell me that I'm being inaccurate. I think that satisfying people's curiosity is the most important thing I could be doing (and usually enjoy doing it). I am normally terse in my writing and would appreciate requests to verbosify.
I appreciate if my grammar or style is corrected (in any of the languages I use here).

Writing a description of oneself for one's fedi profile reminds me of the standard responses to "who are you" and the whole discussion on (a) why those reponses are typical (b) what does this question even mean.

OKAY so this this the Square Panda spelling thing. The idea is that this interfaces with tablet apps for little kids to spell words, and it can detect what they spelled on it. I'm gonna tear it down.
I'm gonna try adjusting the visibility for this thread after this so you should only see this one post.

The faults it has make it a very depressing development for me. It's able to produce very human-sounding prose and is unable not to inject false statements into ~anything it outputs.
First, this is very depressing for people who actually read what they see and remember small tidbits that were mentioned. This makes it way more likely that they're garbage.
Secondly and more importantly, this is asymmetric tool of disinformation creation. It can be used to generate plausibly-sounding wrong statements much more easily than it could be used to generate correct statements. There are people/organisations who wish to do former. Thus, this will remove many of the factchecking heuristics that work today. (This is a fundamental inescapable problem for factchecking of news, and still a bad problem for factchecking of statements about empirically available knowledge.)
I expect us to get way more hard-to-filter spam and not get much in return. I expect Sybil problem to start appearing in places where hardness of simulating a human prevented it from appearing.

Just tried ChatGPT. I asked it a series of specific Qs about areas I've studied in detail.
On all Qs, it gave answers that are plausible sounding but wrong. Not obviously wrong: wrong in subtle ways that need deep domain knowledge to grasp.
The ways humans will be practically misled by this kind of tech if trusted with, say, doling out medical, legal or business advice is horrific.
Letting this tech loose on the world will further destroy search engines that are already riddled with SEO BS.

@robryk@qoto.org Removed bounding wires are pretty common in these photographs. It's often difficult to extract the chip without touching the wires.
Also another fun fact, LTZ1000's technology came from another legendary LT chip - LT1088 RMS-to-DC converter, this is where the unused heaters were used from. LT1088 measures True RMS voltage by AC-DC thermal conversion. The input AC power is dissipated into an on-chip resistor, and you heat another on-chip resistor using DC power until both reach the same temperature, this is the very definition of RMS voltage. It's still the holy grail in metrology labs, and also standard for RF/microwave power measurements. But as far as I know, the LT1088 was the only attempt to do this in an off-the-shelf chip. Too bad it was never a commercial success and went out of production.

Do you know of anyone trying to make any kind of a MastodonAPI-to-{NNTP,Maildir} bridge?

This is really quite fascinating. There is exactly one ISP that is blocking mail from the mail server I run, which is used to deliver mail for infosec.exchange - t-online.de. It annoys me to no end that I see people try to subscribe to infosec.exchange and the confirmation emails are rejected. So, I contacted their postmaster, and to their credit, they got back to me very quickly, but they are basically saying "yeah, you need to use one of the big mail providers if you want to send mail to t-online subscribers".... Ok then. My apologies to any t-online subscribers (who probably can't see this anyhow), but you'll apparently need to use a different email account to register.

So, don't tell anybody, but we're going to announce Palm Pilot emulation in the browser at Internet Archive in the next week or so. I've still got to get descriptions in for the hundreds of apps that are uploaded, and add a few more classics. But if you want to help with that, or just let me know how it's going, ping me here.
But don't tell anybody! It's a secret!
I seems that the answer is (or at least was a year ago) no: https://socialhub.activitypub.rocks/t/activitypub-client-to-server-faq/1941
Weirdly enough Pleroma is claimed to implement it.
Does #Mastodon implement #ActivityPub client-server API?
I do what https://www.w3.org/TR/activitypub/#client-to-server-interactions tells me to:
- I look up my own Actor object and look up its outbox (qoto.org/users/robryk/outbox in my case),
- I send a POST with appropriate 'Authorization: Bearer ...' header,
and then I get 404 (GETs on that URL do succeed and show a collection).
Is client-server activitypub something that is ~ever implemented?

Heh, if you fly away far enough, the sun goes supernova significantly later (at least a minute after it eats the Interloper). I guess (based on the map being screwy: e.g. Interloper appears well off its indicated orbit) that there's a floating point accuracy problem there.
