I'm not. I get the distinction. The point I'm trying to make is that only considering the intended usage is an incorrect approach to design. The consequences of this constrained thinking can be particularly extreme in infosec, but

The thing is, that's not just a technical decision. There are strategy, product, and operational reasons why you might decide to add or avoid SSO. SSO for sign-on can be really complicated and have lots of caveats -- for example, Apple

I was just about to suggest localstack. I use it religiously in personal projects; can't recommend it enough. I haven't started telling it to induce errors yet, but it definitely has that capability. And if you're running it

You're looking for secret sharing algorithms, which is what this is using behind the hood. The classic (used in OP) is Shamir's secret sharing algorithm [1]. The general gist of it, simplified into the 2-of-N case, is: 1. the encr

Yep, versus https://docs.mapbox.com/help/glossary/mbtiles/ -- I had them backwards. My confusion might have been because of the name similarities (mbtiles vs mvt), which took me 3 tries to even just type corr

It might be that pbfs are stored inside sqlite? The whole thing is really incredibly confusing to be honest. What I can tell you is that my vector slippymap XHR is requesting .pbf files, so that would definitely imply protobuffers as the wi

You're mixing up the formats slightly: MVT is sqlite with a particular schema; OSM raw data is PBF with a particular schema.

I believe, but haven't bothered to profile, that they're lighter. You can also pre-"render" the vector tiles and store them in eg S3. All styling is done in-browser, which means you can do neat things like swap out the s

It's worse than that actually, as in some cases the single underscore is actually meaningful (see the SO question linked in [1]). My recommendation is always to use a double underscore for throwaway variables, particularly since droppi

All money is fungible. That's the point of UBI: let individuals decide for themselves what the best use of it is, instead of having the state decide for them. Different people have different wants and needs. Would you consider toys for

Replacing chemical combustion with electrical heating in a heat engine was an idea that popped into my head a number of years ago while thinking about the heat exchanger for Skylon's SABRE engine. I'll skip the drunken, derailed t

That's also what I was taught as a best practice, but it's not always possible. Otherwise, best practice is to index the gears (ie mark a specific tooth on each). That way, when you disassemble the gearbox (it's bound to happ

Don't forget that for the vast majority of that trip the atmosphere is essentially negligible. A better comparison would be a vacuum tube train with a(n approximately) constant 1G handicap. From the perspective of the tether, any pract

There are definitely some good arguments on either side of the federation discussion, though I personally tend to lean more towards the Moxie side than the optimistic one. That being said, a big part of me wonders if (assuming you could fin

I agree that for traditional launch systems it doesn't make that much sense -- particularly in light of the recent development of reusable (or at least, partially reusable) rockets. That being said, I think the math changes somewhat fo

I wouldn't exclude the possibility that the eventual plan is to do both -- or to manufacture the BFR (the rocket part) in one location, and the BFS (the spaceship part) in the other. The article does mention that the LA location is int

This would have the added benefit of increased efficiency due to the Oberth effect; however, I'm still not sure you could use it for unassisted interplanetary flight. The last orbit, by definition, must occur before the craft passes Ea
