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?

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.

Searle, is that you?

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.

I've heard this can happen where money laundering is suspected. Apparently the banks aren't allowed to tip off the account owner that they're being investigated, with the result that the account owner's subsequent interactions with the bank become kafkaesque.

The drug in the article is roflumilast, which seems to share some structure with the nootropic ampakine CX-546. I've never consumed that, but I've had some experience with IDRA-21 doing something like what the article describes, such as having vivid dreams of minor chart hits from decades ago that I'd previously gone a long time without being reminded of.

Unauthorised third-party modifications and add-ons may end up being part of the solution here. It's already established that this can be a viable business model with e.g. car accessories, games consoles and printer inks. I can see a market for one-off DIY modifications to various things that unlock what was intended to be a subscription feature.

A related issue is the increasing possiblity of devices being effectively bricked because some cloud service or online system has ceased support. Could there be a niche for a company selling improved after-market firmware for other companies' devices?

I never thought I'd see the issue of pulse selection in spallation neutron sources referred to on HN, let alone linked to music theory. In practice, most systems that select a subset of these pulses will select 1 pulse in every 2^n pulses, so fancy patterns aren't needed. But I work at a facility where 1 in every 5 pulses are removed in order to supply another part of the site, and where the particular instrument I work with uses 1 in every 2 or 3 pulses. At the moment, the selection of 1 in 2-3 pulses is accomplished with a spinning disc ('chopper') with a hole in it, to let though the required fraction of pulses. But the spin speed of the disc must generally be constant once set, meaning sometimes it lets though one of the missing 1-in-5 pulses that were already diverted somewhere else. We would need a better switching method to let through arbitrary irregularly spaced patterns of neutrons. I think I worked out once that it could offer the most advantage when running in our 1-in-3 mode.

There's imechanica.org, I followed it more closely in my time at university but not sure what it's like more recently.
