We did pretty much that for the Sony rootkit didn't we? Thankfully the eBay stalkers revealed where the limit turned out to be.


I work there, and when we give tours and people raise the issue, I like to point out that we had the name first and so we're not changing it. Though we did once get an official reminder that, to avoid ambiguity, we had to always say 'ISIS Neutron Source' in full on immigration and customs paperwork, especially in anything that also uses the word 'nuclear'.


Are there any clever tricks for the data processing involved here, given that the delay is a shift in the time domain and the Doppler effect is a shift in the frequency domain? Maybe involving fractional Fourier transforms, or wavelets?


Lots of clever tricks, all ITAR controlled.


Uninformed FUD, not a single dsp "trick" related to passive radar is ITAR controlled. The equivalence the OP mentioned is literally described in every undergraduate dsp textbook.

ITAR is only a US law.


you’re free to share tricks you think the Gp should be aware of.


Good point. I wasn't sure from the given examples that overuse of classes in this way was all that harmful, e.g. the performance penalty hopefully shouldn't be all that significant. But then I remembered all the Python code I've seen that was obviously written by capable and experienced C++ programmers.


For a real-world use case, maybe cruise ships? Internet service on the ships is expensive if it works at all, but that's not necessarily what people need - they just need to be able to exchange whatsapp style messages with people already on the same ship, especially if they can't find each other. Music festivals, mentioned elsewhere in this thread, might face a similar issue as they can be in remote locations.


The McGurk effect https://www.youtube.com/watch?v=2k8fHR9jKVM is another example, which might be described as people learning to lip read without them being aware that they have done so.


Apparently I can't lip read, as I never heard anything other than "baa" even as the video was claiming that I should be hearing something different.


Yeah, I don't understand what I was supposed to be seeing or hearing in that clip, and they never bothered to explain it.

The guy says "Baa" and we see his lips move accordingly. Then we hear him say "Baa" again, but this time he's obviously pronouncing something else, judging by his lip movements. We don't know what he's saying (or at least those of us without lip-reading skills don't), but nothing unusual or tricky seems to be happening.

What am I missing?


From making the same motions with my mouth I was able to figure out that the other thing he's saying is "faa", so I'm guessing some people literally hear "faa" even though the audio is "baa"?


I hear “faa” when the mouth looks like it’s making an “f” sound (and apparently that’s normal). Are you perhaps not a native English speaker?


Yep


Searle, is that you?


What if the people translating the characters were neurons? ;D

Also, it's rich to imply humans don't do literally everything LLMs are accused of to argue they're fundamentally different from humans.


I always knew my experience with RISC OS wouldn't go to waste!


Any way? There are left-leaning social positions that would be entirely expected from a modern tech-focused VC company. I support those causes and positions to various extents (if not always their approach to advocacy and addressing other viewpoints), but they're still left leaning.


+1 for also looking for a tool like this (online or otherwise) before, and being disappointed with what I found previously. Two projects immediately spring to mind: firstly, we have a theodolite to align some lab equipment, which I'd like to add a live digital camera to, and secondly we're designing a material heating system based on halogen tubes, for which we need to optimise the shapes of reflectors around the bulbs, subject to some geometry constraints.

I'd not seen the sharedigm.com platform before either, possibly itself also interesting for other things.


The first task could be done with a tool like this, but it is not a project for beginners. The second requires a different tool, a non-sequential ray tracer. See https://community.zemax.com/got-a-question-7/sequential-vs-n...
