On the one hand I get why that is - the calculus notion of infinity is the one that tends to be useful in applied math - on the other hand it's a shame because the set theoretic notion of infinity has more to offer to someone trying to

Well, there's less of it, since typical airliner cabin pressure is equivalent to being at 8000ft altitude or so. Do you typically spend long durations driving in the mountains?

If by "embedded" you mean "MMU-less", it's definitely rare these days, even though historically general purpose computers had binary loaders long before they had virtual memory. NuttX is the only one I can think of

On Reddit at least, posting links to your own site or your own content on third party sites tends to be seen as "self promotion" and at least a little bit icky, even if you don't financially benefit. Some subreddit communitie

I feel like it might be more accurate to say the 60s and 70s were sort of a golden age of logo design and perhaps of graphic design more generally. Glaser was certainly one of the most famous practitioners of that era but elevating him over

The smallest Lattice iCE40 are under $2 in volume, it may be "overkill" but also pretty tough to beat economically at low quantities. Especially keeping in mind one of the limitations of these MPW silicon runs is the parts you get

Cost (reputational as well as CSR hours and the actual replacement units) of a bunch of warranty claims for bricked units is a factor too. In practice pretty much every embedded device I've worked on that has supported in-field firmwar

I would not take it as a given that the individuals laid off were the worst performers at the company. It could be that they were highly compensated and deemed too expensive, or happened to work in the wrong department/business unit.

The straight style is more common in US home kitchens; the Y-shaped style seems to be more common in Europe. In the US there has been a trend of chefs and food writers evangelizing the Y-shaped peeler. In my experience the straight style is

I think in this case the behavior is that the initial generation of the password is random, but subsequently it is, shall we say, "trivially deterministic": it (intentionally) always spits out a cached copy of the initial randomly

Yes, that is the architecture of a modern offline SMPS. But the rectification losses are minimal compared to other losses in a PSU and there are options, like active rectification, to improve efficiency in that block if needed. I will conce

Long distance (including room-to-room) distribution of low voltage DC power is inefficient due to I^2*R losses in wiring unless impractically large wire sizes are used. There may be some marginal efficiency gains to be had with high voltage

One of the more confusing examples of this I've encountered was a manufacturer describing a material with improved eco-friendliness over a prior version as "dark green"... taking the color metaphor perhaps a bit too seriously
