I'm a big fan of LiveView, but when you get to a very high degree of interactivity or anything that needs to work well offline or with bad signal quality then LiveView is not the right choice.

The main advantage should be proper base station handoff. If you have a house that can't be covered by a single wifi access point (or an office), then the normal approach is multiple APs with the same SSID. It's a bit of a hack

That's interesting. I didn't actually know the definition of uintXX_t. I was actually doing this with C90 most of the time, and using types we had defined (rather than from stdint.h). Sounds like they were more equivalent to int_l

It turns out you're right, and that's how I've actually written these examples in the past. A sibling comment provided a citation, and that I should really have been writing uint_leastXX_t: https://en.cppreference.

I can't remember the precise wording in the standard , but sizeof() is effectively "how many of the minimum addressable thing do you need to store this thing". The "minimum addressable thing" is called a byte, and o

Is it? Cool! I haven't done anything with an Arduino for a while, and only used larger AVRs.

Yeah, the only time I've done it, it was an ARM based chip that didn't actually have a full MMU (i.e. full virtual addressing), but did have an IOMMU.

I believe (without supporting data) that most altnets that are expanding coverage to people with poor broadband are government funded. The economics in London are quite different than that of a rural village.

I'm guessing the virtual memory trick it to set up a page mapping so that the next bit of virtual address space after your hash table, is the same physical memory of the hash table again. The power of 2 restriction is needed to make th

This is a reasonable argument for higher cost and lower capacity. It is not a good argument for unreliability in a service that should be fairly mature by now.

Bluetooth from an regulations point of view has the same power limits as wifi (it's in the same 2.4 Ghz ISM band). In practice Bluetooth devices are small which limits both antenna size and desired power consumption so they tend to ope

I have a close friend who lives in Edinburgh (Scotland) who has an electric cargo bike. Edinburgh is full of very steep roads, lots of them cobbles rather than tarmac. It's also cold and wet in the winter (although nowhere near as snow

I think "self-limiting" is a key point here. People who are moderately drunk are not very dangerous, and people who are very drunk are just not capable of cycling - it requires a certain degree of coordination.

I tried my friend's cargo e-bike for 20 minutes in Edinburgh - I didn't even notice that lag. As i turned up the dial for the motor, it just felt like I was turning down the physics! Everything just got magically easier.

That would work to a point. There is still a hole based on your trust of the underlying implementation. If you haven't read "Reflections on trusting trust" I recommend it ( https://www.cs.cmu.edu/~rdriley/

No, but you have to look for (and talk in terms of) actual level of capability rather than just "you've done it for a while".

Until the Nix team is happy to even enable flakes by default in releases, I don't think it is reasonable to expect people to use them by default.
