Technically getting one surface flat is easy. Hell, it’s one of the first thing you learn in measurement science (three plates and perfect smoothness). However a mirror isn’t just about being flat, it is also about light reflection. And that makes it more interesting. In a perfect vacuum, you could do a silver mirror without the glass and have it be perfectly flat and not worry about oxidation. But the reality of making that mirror stay perfectly reflective means that glass or similar is usually involved. And then you move away from the perfect flatness problem (relatively easy) to perfectly parallel planes (significantly harder).

Furthermore, keeping a plane or surface perfectly.flat after manufacture requires uniform temperatures, which are rarely present in amateur telescopes.

The end result is almost always the introduction of additional error.

Every interface (mirror or lens surface) adds error, and that error is multiplicative. The question is whether that error is worth the convenience in form factor, and that isn’t something that can be easily answered. Sometimes you need to build it and use it :)

Depending on the carrot, the skin can be significantly more bitter. And sometimes peeling can be quicker than trying to scrub dirt out of particular lumpy carrots.

YMMV

I want to take the little one on the right and put it in a teacup.

Unpopular opinion (largely discredited in anthropology circles): cold weather encourages resourceful behaviour and improves human cooperation. In climates where you can survive winter outdoors, homelessness is not as detrimental to continued existence. Three walls and no roof is fine in a slum in Florida, but harder to pull off in Minneapolis.

This societal coordination which is required to survive winter leads to more orderly and more socialist civilizations. Because hairless apes have no business being in that climate. So it is human ingenuity that is selected for – and that includes development of systems of cooperation.

If I extrapolate, our space faring descendants will face much bigger hurdles, but ideally will develop even better systems to deal with it.

Bonus picture. Me doing arctic exploration.

The premise here is that Trump loses but refuses to back down, attempting to forcibly claim victory. If Trump legitimately wins, there is a different path. Then…

Assuming multiple systematic failures occur simultaneously, including any of: actual voter fraud, fraudulent electors, congress refusing to certify, a captured supreme court acting in favour of Trump, or actual insurrection on or before Jan 6th.

I actually expect the US Military to step in. Every member is sworn to uphold the constitution. But if the constitution has been discarded, then I’d expect them to step in to restore it.

Failing that, the US likely fractures and we leave the Republic phase.

The premise is ridiculous, so I wonder: how serious does the book play out, or is it self-aware enough to lampshade things?

1000 km and 5000 seconds. Doesn’t seem very capable of hitting much, unless it flew intentionally a very high arc.

Love the solid rocket exhaust aesthetics though. Too bad it is produced as a weapon.

Considering how well received this game was, perhaps it is more about marketing or misunderstanding the genre appeal?

Damn. Need to wrap that whole bar in a try: except: that just silently fails. Solves all the issues and you go to another bar.

Cat!

The genre is much older than this. The market is huge (something like 10-15 billion $USD) with about 50k different self help titles being published every year. Obviously no bookstore is going to stock 50k different self help titles (except maybe Amazon). But much of this market is served by special interest bookstores, like religious bookstores attached to churches or whatever. And those have existed forever!

I’m old enough to remember the 1980s and the parenting advice books that told my parents to beat me with a wooden spoon – that they purchased from their church. It biases me against the genre somewhat ;)

Self help books tend to be part of a radicalization pipeline, where the authors are considered “experts” because they have a published book. Once you’re in the pipeline, like youtube conspiracy videos, eventually you’ll end up buying into antivaxx and other woo.

Poor kitteh. Now show us your bloodsucking fangs, fluffy vampire.

He cites his work as being a variant of a patch submitted by another developer, Josh Poimboeuf. It’s a team effort folks :)

Cat was caught swearing. Had to wash its mouth out with soap.

The US is broken for many reasons.

The Canadian Supreme Court, by comparison (in fact all judges in Canada) are merit based appointments. So far we’ve managed to avoid political appointments, for the most part. Although current conservative rhetoric is starting to target the courts.

Most functioning western world countries do not have partisanship in their courts.
