This is exactly how Stripe works. Except you don't even need the credit card info at all, even initially – Stripe handles that.

Now that's currently only online, but they're releasing a point of sale product soon too. But even with that, you connect to their card reader and receive a token that you can use.

It probably didn't. I'm guessing the writer, like myself, didn't even think of homonuclear molecules.

I don't think it's wrong, tho definitely (somewhat) less precise. An ionized molecule is still that molecule.

According to sibling comments of your own, you're wrong. Humans deliberately solve cubes with the least number of moves and even compete to do so. Generally tho, you're probably correct.

From [Rate Limits - Let's Encrypt - Free SSL/TLS Certificates](https://letsencrypt.org/docs/rate-limits/):

> If you have a lot of subdomains, you may want to combine them into a single certificate, up to a limit of 100 Names per Certificate. Combined with the above limit, that means you can issue certificates containing up to 5,000 unique subdomains per week.

Hell, even waiting an entire day (e.g with results sent via email) might be reasonable for some searches.

I'd imagine lots of hosts don't allow users to setup Let's Encrypt so then the obstacle is first migrating to a host that does allow it (or includes direct support for it).

One problem with your metaphor about mountain climbers and mountain climbing is that the most efficient way to scale a mountain is probably to just take a helicopter to the top. Mountain climbing, like lots of other things, _must_ be constrained, in some way, to be _meaningful_, and the constraints _chosen_ reflect the _purpose_ of the endeavor. But then, specific constraints, e.g. the tools and methods 'allowed', become their own 'thing' (while continuing to interact with and evolve with other related things).

> maybe the stress of commuting is a net negative

Commuting is considered one of the _most_ negative parts of a person's day, such that common advice is to seriously consider living closer to work at the expense of other amenities.

I use GitLab for almost everything. They've got pretty nice LaTex support (via KaTex I believe).

> running JS on the server

Huh? Enough people apparently knew JavaScript well enough that running it on a server was really useful. Why's that not a real problem? (Not being able to do so.)

> rarely do more than one client application access a database

That has not been my experience!

All the SQL databases with which I'm familiar support large string columns. What's the downside to just stuffing your schema-less or volatile-schema data in one of those?

The Koch's give money to lots of nice people.

I'm pretty sure most workers in NYC live 2+ hours away too, unless they're in a rent controlled or rent stabilized apartment (of which there are many). Subway commutes have gotten hellishly bad in the last few years so even people with previously more moderate commutes often have much longer ones now.

If the service has only the hash of the password, then that's the password, which would then be subject to the same problems as a "cleartext password".

> When secrets come in, immediately store them (ideally at the web framework level) ...

But, in practice, a lot of this stuff is being logged by things like proxies that could be several layers in front of the "web framework level".

I'm guessing they were referring to Google Voice.

Wasn't it the girlfriend?

Why shouldn't we all get off easy (or easier)?

I'm pretty sure Tor exit nodes in particular are very public and easy to spot by ISPs and VPS providers, which is why they're very difficult to host at all even now.

Traffic on the Tor network itself is designed to evade tracking or interception but exit nodes are required for communications to reach outside Tor.

> Gravity is not radiation.

'Gravitational radiation' is, apparently, a thing; gravity waves basically. It's not _electromagnetic_ radiation tho, which is what I'm guessing what you meant.

I don't think it's crazy to think that gravity is propagated at the speed of light but that we can't, and likely won't ever be able to, measure any gravity waves smaller than those generated by extremely large-gravity systems.

Based on other comments, and my own very limited knowledge of the relevant physics, there's no way to do this from Earth; all of the black holes (and binary block hole systems) are too far away for us to reliably aim a laser beam to slingshot around the black hole as is being described.

But the general form of what you're describing isn't any more outlandish than a time capsule, i.e. 'transmitting information into the future'.

But no, sorry, you can't see the past with the paucity of black holes near the Earth (and ignoring all of the other impediments to such a thing happening).

It seems like you would need to encode the parameter value; and in the same way as anything else.

There isn't a limit of URI length per the relevant 'specs'. There are generally limits imposed by _browsers_, and probably web servers too tho.

Mathematics has its own version of 'empirical proof': a constructive proof, i.e. demonstrating that a method (algorithm) can construct a particular mathematical object with specific properties.

I don't think it's really the case that all branches of mathematics really have a 'common basis' as much as that they're all equivalent. It's pretty common to map one branch to another, e.g. arithmetic to set theory, but then once that's been done there's no real reason to write proofs in a particular branch in the formalism of another.

> The idea is that mechanising proof and making it more algorithmic will make it more like what the layman thought proof is , but it at the same time raises the question, what is this all for? Ie maths is what mathematicians do. I think it admits to no clearer a definition. So it’d probably make sense for mathematicians to decide, what precisely is the role of proof?

"A New Kind of Science" has some insights about this that I appreciate greatly. Mathematicians don't bother to enumerate everything that's formally ('mechanically') true, even tho there are some interesting truths to be discovered in that fashion. They instead explore the 'tree of truths' based on history, intuition, and even fashion.

Ultimately, even the most mechanical formal systems are, or can be, nebulous and 'philosophically strange'. Consider the axiom of choice as but one example – there are different set theories depending on whether one accepts that axiom as 'reasonable' (or 'true') or not!

How many homeless people could one even very wealthy person help in San Fransisco or Silicon Valley? Even just building a homeless shelter, which I think are still uniformly pretty terrible places, is probably near-impossible; and not just because of the opposition from residents to them being built in their areas or neighborhoods, but also the regular, general opposition to any new development.

And just giving homeless people a better place to live is only one, tho extremely important, dimension along which homeless people can be helped.

And then of course one should expect side-effects to any help one would give, e.g. increasing 'demand' for help for homeless people. I'd imagine one reason why there's so many homeless people in San Fransisco is that it's already one of the best places to be homeless.

I roughly agree with your diagnosis about why libertarianism is considered right-wing but your example elides some pertinent details, e.g. segregation was sometimes (often?) imposed on private parties by the relevant governments.

I find that pretty obnoxious to read (or listen to). It's much more natural, in my experience, for text (or speech) to use pronouns generally and explicit names sparingly.

If I'm remembering the book correctly, it's discussed at some length in a later chapter; maybe the last chapter.

This is an idea I've seen popup over and over. I suspect the transaction costs in using, let alone maintaining, the tools needed to do this well are what prevent it from ever reaching widespread adoption. Consider the 'leftpad' debacle as one example.
