Before I viewed the link in your post I thought you were talking about that “IPv8” draft. I have some experience writing networking code, and based on my experience I will say that the meow draft has a slightly better chance of resulting in a useful implementation than the “IPv8” draft. I didn’t read enough of the “IPv8” draft to make it to the parts you are referring to. I didn’t need to read that far to figure out that it was worthless. The meow draft I can see is based on TCP. But I think before it can be implemented IANA would have to allocate a protocol number. And the meow draft seems to fall short of the requirements for such an allocation.

Sometimes I know enough about a topic to verify the correctness of an answer. In those cases there is less than 10% chance an AI can give me a useful answer to the question. But there is a non-zero chance. One example from my own experience was that I wanted to know the git equivalent of this command hg log -r 'children(.)'. I have searched for an answer using search engines. I have asked some people who are promoting use off git. All of that lead me to suggestions that would only produce incomplete outputs. And for years nobody I asked could suggest a fix for this. Eventually I asked an AI, which initially gave me the same answers I had seen before which did not work. After pointing out 2-3 times that the suggested solution didn’t work, the AI eventually managed to give me a useful suggestion. It hadn’t produced a fully working solution, but it had given me a different approach that I was able to turn into something working by myself. The key point was to use the command git cat-file --batch-all-objects --batch-check as part of my solution. I wouldn’t have managed to find that solution without the help of AI. But using the AI certainly wasn’t a quick and easy way to a solution either. I had to go through loads of useless output from the AI to pinpoint that one tiny piece of information that was useful. So my conclusion is that current LLM are sometimes better than nothing, which is a pretty low bar to meet. And they are very far from the all-knowing infallible oracles that proponents say they are.

One needs to be able to judge whether the output from an AI is trustworthy or not. Anyone who cannot correctly make that judgement isn’t smart enough to be using AI.

I noticed that as well and think that’s an interesting result. The asymmetry tells us something about how kids learn to multiply, though I am not sure what that something is.

I don’t recall if it attempted falling back to TCP. There was no blocking on the network where the DNS recursor was hosted. But many authoritative DNS servers lack TCP support. In any case it also failed resolution with authoritative servers that did support TCP. What I do recall observing was that the BIND 9 recursor would try all of the different authoritative DNS servers one after each other. It would simply ignore every DNS response if it had taken more than one second to arrive. Even after having received and ignored perfectly valid DNS responses it would keep sending more DNS requests over UDP to other authoritative servers for the domain.

I think TCP window scaling is supposed to deal with that. But I have also heard that computers used on ISS supposedly all do remote destktop to computers on the ground when they need any outside communication. But I don’t recall the source, so I am not sure if this is accurate. Speaking of 1+ sec latency, some point in the past year I discovered that BIND 9 would completely fail to perform recursive lookups once latency exceeded 1 second. That came as a surprise to me as prior to that my experience had been that it was a robust DNS implementation.

Sounds like a case of somebody rolling their own cryptography without knowing what they were doing. Why are they not using a mainstream cryptographic hash that has been analyzed for years without finding vulnerabilities?

Kunne du ikke tilføje en AAAA DNS record så siden kan vises på en internetforbindelse uden legacy protokoller? Hetzner har support for det per default, så sandsynligvis er det kun DNS der skal opdateres. På længere sigt bliver det også billigere for dig selv at holde siden kørende hvis du udbedrer den detalje.

I watched this and spotted the 1/9 mistake immediately. Except rather than me being absolutely confident I had spotted a mistake I spent the next several minutes pondering what they had seen, which I had missed. After they had fixed the mistake I was wondering why they didn't conclude it had to be 2 or 8, given that they had already proven by contradiction that it could not be 1 or 9.

The straight binary encoding wouldn't be able to position LED number zero, since it would be turned off in all pictures. And I think the algorithm will probably be more robust with LEDs that are turned on in many pictures compared to those which are only turned on in some of the pictures. You can restrict it to assign each LED a number in which exactly half of the bits are one and half are zero. It will still be logarithmic time, but with a slightly higher constant factor. An LED which is not visible from both camera angles will obviously be a problem. That problem is caused by the positioning of the cameras and will be the same regardless of whether you use the logarithmic or the linear algorithm. If you are encountering that problem, I think it's best addressed by using more than two camera angles.

@standupmaths has done similar projects in the past. As far as I recall he did the mapping more efficiently than by lighting the LEDs one at a time.
