> Is there not opportunity cost in both directions?

Yes, but there are more working age people outside the US than inside the US, and they’re willing to work for less than people in the US.

> At some point someone needs to have a reason to trade with us right?

We trade plenty of goods, and we trade more services than goods. The people that produce services tend to be college educated, which is negatively correlated with conservatism.

> Specializing only works when line goes up forever.

I’m not sure what you mean by this. If you want cheaper and better quality goods and services, then you need specialization. Every country had some competitive advantage, whether it’s natural resources or specific human capital. When an economic downturn happens, it’s not like that competitive advantage suddenly moves abroad. If it’s cheaper to make things in China, it’s still going to be cheaper during a recession. Raising tariffs on China _maybe_ means companies move manufacturing elsewhere, or _maybe_ means they just pass on costs to consumers. I’m willing to bet money it’s the latter.

Great approach. I ctrl-F'd for databases, good info there generally. The only thing that gave me pause: a startup doesn't need to focus on SQL vs. NoSQL in 2025 with such good json support in the most popular SQL databases. Just use PostgreSQL or MySQL -- whichever your engineers have more experience with -- use CloudSQL or RDS which will take care of the hard stuff like backups and replication for you, use read replicas for BI with a good visualization tool, you'll be good with that for a good while before you need to fork over 5/6 figures for Snowflake or anything else.
Numeric code can, but compilers have to do a lot of string manipulation which is almost impossible to optimise well in JS.

This is mostly about the tooling and ecosystem, they want to stop things from depending on the internal workings of the compiler. If you just want to write and compile TS you'll be fine, it does not mean breaking changes to actual TypeScript grammar.
Isn't the problem that life is in fact zero sum? Most of the really important things (land, attractive spouses, desirable jobs, etc.) are extremely limited resources. I don't see how we move past zero sum when there is not enough of the things that people are fighting over to go around.
This is true, but it is more nuanced than that. It also has to do with familiarity with common patterns and willingness to accept that not everyone has the same style you do.
Luckily the Australian BOM Weather Station specifications require that air and soil temp sensors have a -60° C to +60° C range with a 0.1° C resolution and a ±0.1° C accuracy.

The specs are in attachment 2 of the BoM Observation Specification manual.

> At every place X in the following expression, introduce a boolean negation if there isn’t one (or, equivanently remove one if there is), and

I think it should read:

At every place X in the following expression, introduce a boolean negation if there isn’t one and remove one if there is, and

Maybe even better:

At every place X in the following expression, introduce a boolean negation.
If you get two concecutive NOT's, they can be removed.

Next, I don't see how

is the negation of

> But then the children of immigrants in America who are associated with that country wake up, and suddenly 8 hours later you're a monster.

Mostly what this immigrant effect has produced in America is a bunch of movies about how the writer of the movie hates their mother. (EEATO, Turning Red, etc.)

But a funny one I've repeatedly noticed in West Coast Japanese-Americans is they have West Coast progressive political beliefs (basically, noone should ever be punished for crimes because it's mean) at the same time as Japanese ones (copyright violation or disrespecting important big companies should get the death penalty), and I don't think they've noticed.
Whenever you have a proposal like this that essentially laments that we don't have the nice shiny thing, it's quite useful to take a few step backs and ask "well, why don't we have it," and try to consider some of the problems with it. This paper is no exception--advocating for a return to a Smalltalk/LISP machine approach as opposed to Unix; why don't we have those things?

The facile answer is the "no true Scotsman"--we've never really had a true, whole-system approach to this, only approximations, and if only we had that true, whole-system approach, everyone would fall in love with it. I'm not persuaded. We were forced to use a Smalltalk environment for one of our classes, and the reaction was pretty universally negative. Not because it was a lamentably incomplete instantiation of a wonderful thing, but because if you screwed up--as anybody is wont to do--you would just absolutely and sometimes irreversibly hose the entire system. Imagine trying to poke at an error stack trace resulting in the only editor you could use to fix it breaking with the only means of recovery going back (outside of the all-encompassing environment, mind you) to an older version.

So I think that's the real reason these systems never took off: "everything works together" too often becomes "everything breaks together." Hotpatching code sounds nice, but it now means you get to deal with stuff like "oops, the global cache has both the old and new version stuffed in it and something else is hosed as a result." Replacing "sqrt" with "mysqrt" everywhere also implies the ability to replace "open" with "vfsopen" everywhere... only to accidentally map it to a VFS that has no files and now you can't open any files on your system from any application.

Thanks, and the purpose was to show what's possible on modest hardware that most people have. We have created gigabytes of graphics that live on the gpu for more complex use cases and they remain performant, but you need a gaming gpu.
Perhaps we have differing definitions of "technical workers" ? Here in the Bay Area at least there are a number of companies which are replacing "senior staff" with an LLM and a junior engineer. The argument is that this combination is "cheaper" than the salary paid to the senior engineer. For me that is exactly analogous to replacing a factor worker with a robotic work station and a technician to maintain the robot. There is a ceiling on that junior engineer's career which occurs when they are themselves replaced by another junior engineer to reset the salary cost.

We've seen some of them post "Ask HN's" about what they should do now because they aren't getting callbacks or any traction on their job search.

What I haven't seen yet is this replacement penciling out to actually be less expensive when you look at time to complete tasks and support costs from faulty code/designs getting fairly far into production before being re-tooled. That may turn out to be endemic (at which point the replacement will stop and the trend will reverse) or there may be developments that mitigate these costs and get the combination to be more cost effective. It's something I watch for, evidence of it going one way or the other.

This has the same problem. It takes a long time to make back the $1000.

Do you think it is a) easier and cheaper or b) harder and more expensive, to deliver services in a vast range of languages or a single language?

You can't run Java either as it's compiled to bytecode, yet when someone says "we made Java 10x faster" you wouldn't assume that just the compilation got faster, right? When people market Rust projects as blazingly fast nobody assumes it's about compilation, in part because a blazingly fast Rust compiler would be a miracle. Outside of this comment section people have always been using a programming language name for this because everyone knows what they mean.

It would be possible that MS wrote a TypeScript compiler that emits native binaries and that made the language 10x faster, why not?

HCN gas does smell a bit like Hydrochloric Acid.

Not like almonds at all.

Otherwise known as Muriatic Acid when used in pools, hydrochloric is an aqueous solution of HCl gas, which is a very acidic gas, highly soluble in water. It is usually supplied in its saturated solution of approximately 37% concentrated HCl gas dissolved in water. It's a smoker, as soon as you open the bottle of concentrate, vapors of HCl begin to escape and if you get a whiff it's pretty rough.

HCN can be supplied in gas form (pressure cylinders) if needed, but most cyanide is supplied as a solid salt like NaCN or KCN, which are "basically" non-acidic forms of cyanide.

These crystals can be dissolved in water (makes a very toxic solution) without the release of very much HCN gas, but the solution must be maintained in a relatively alkaline condition, otherwise if it is acidified the solution will liberate HCN and it smells like an acidic gas alright.

A little bit like HCl but even rougher.

Well in my back yard during college there was a big cherry laurel and once the little fruits were ripe it would be infested with birds who were wolfing them down. It's hot even in north Florida and after a while some of the fruits would get fermented to a certain percentage of alcohol. The birds were really partying then until it got to the point they would fall out of the tree drunk.
Right, just like a semi truck is a truck as well. It's just larger and more expensive.

But comparing the two doesn't make sense.
Right. There are dozens of those things on Amazon, usually called a "power station". 1.1KWh costs about US$700. 2KWh costs about US$1000. This thing is 1.2KWh for $1000.

I met a dutch guy a few years ago in a VR event whose company was focusing on VR cozy, open air environments. The idea was to help people living in oppressive conditions - think bedridden, long hospital stays and the like.

In case of handling exceptions (and similar stuff), I also prefer avoiding unnecessary nesting.

For two (or more) equally valid, I prefer keeping same nesting.
Good clarification! Smarter backup batteries like Pila or Powerwall can be configured to dynamically charge and discharge, giving the benefit of outage protection and energy management. For example, charge up from the solar power you produce at home, and use that stored solar power to offset energy usage at night or when utility power is expensive. They they have a "backup reserve" setting which allows you to set a minimum charge to always be stored for an unexpected outage. Smart features like "Storm Mode" can use severe weather alerts to automatically charge up to 100% ahead of an outage to ensure you're prepared for possible outages

Huh. I always sorta associated the word with a voltaic pile ( https://en.wikipedia.org/wiki/Voltaic_pile ), which... https://en.wiktionary.org/wiki/pila gives an etymology of coming from Latin's "pīla" = "pillar", which feels close? Or maybe it's just a coincidence.

Huge interest in the field. Schools unable to teach the craft properly.
You are touching on an inherent truth in TFL, which is that there are nearly infinite equivalent statements for any logical sentence.

The idea for the article was to make a real example of logical equivalence, as books on the subject stay pretty abstract. - like others have mentioned, in the real world there are smarter choices to be made.
I assume that future AGI which is smart enough to control "general purpose robotics" is probably smart enough to design robotic forms that make all the current stuff obsolete anyway.

Like the article says, physical world data is too scarce to jump straight to powerful robotics first.
The market exists - I have a product from another company - Bluetti - (1).

The Pila is a beautiful device, but that beauty comes at a price - it's a lot more expensive than, say, Bluetti's range of portable power stations and others too. They are also expandable, connect to solar panels and so on, and apparently the German market has embraced batteries like this with solar panels to give your home a degree of independence very easily.

And if this post was about a TS compiler that emitted x86 executables you would be wrong and find out that it is indeed ambiguous.
The point IMO is not to backup your whole home though. That already exists with Generac (20-50K if you need to dig a new gas line) or Powerwall (10-20K depending on electrician and needs). All need permits.

This is meant as a more precise, room-by-room backup solution!

Congrats! It's amazing to see what CE has inspired! Thanks for the shout out :)
For folks that are looking for true whole-home backup, with every load protected, investing in something like a Powerwall would be the way to go. I don't see Pila trying to compete with whole-home systems. We were inspired to build Pila because many folks I've spoken with over the years are most concerned just about backing up a few key loads (fridge, wifi, charging phones, some lights). For them a $10-30k whole home system is a lot of extra spend, and if they rent those systems may be off the table to begin with.
I see where you are coming from but that's unnecessarily hostile.

> There’s a difference between simplifying a concept and stating it plainly.

You are right, but they are not mutually exclusive.

The analogy you used with novel, short story, and poem/haiku also doesn't demonstrate your point: it's not like you can compress any novel into a short story, let alone a poem. If you're into games, try equating AAA-quality 3D games to novel, high-resolution 2D games to short stories, and pixel art games to haikus: it doesn't make sense and it's ridiculous.

I respect that you are passionate about the medium you choose, but what you claimed about novels and poems, as per your own words, "they are both wrong" at best. Don't generalize your personal experience to everyone else, there are kind, hardworking people out there writing novels and poems who love short stories just as much -- maybe what you need to do is to find those people instead of spewing your unwarranted anger over them.

Yeah it helps if it is properly formatted and intended to be easy to read. Style takes effort. A lot of us let emacs handle the formatting - auto indent and something like paredit to move lists around. Once you get a feel for how the tools move things it is a bit easier to predict, but even then it takes someone putting in effort to make it maximally readable.

Thanks for taking the time to answer. That was a perfect level of detail to give me a broad, high-level vibe on MagNav. And the answers are about as I expected. Approaches which serve as an alternative to a ubiquitous, cheap, COTS tech (like GPS), are interesting. They're usually driven by highly specialized use cases where the cheap COTS default isn't always quite adequate and there's a small but meaningful number of customers with challenging requirements and deep pockets.

I imagine larger military drones which need to navigate autonomously for extended periods over denied environments in all conditions are very interested in MagNav as a component in their sensor fusion suites. Even narrowing the current position to less than a square kilometer would make the identification problems faced by other sensors like optical much easier to solve.

> Western standards didn’t apply here. India had its own definition of democracy.

I think this is core thrust of narrative of Indian state and its card carrying supporters. On ideological part this of course makes sense. But practical aspect of cheap cost of informational bit vs physical bit that makes state so obsessed with this. As it makes so easily achievable.

It would be very much clear to anyone who do not spend whole life on social media dream world in India that physical infrastructure will not be reaching of western standards at least in this century. On the other hand informational infrastructure very much reachable if not already reached. Consider Indian companies do so much information /data processing for West already.

Hence all emphasis and obsession on narrative building.

A community is made up of people, not real estate, and if you get priced out of your neighborhood, it is of no benefit to you. It's a "non-issue" like me kicking you out of your house and fixing it up, and then for some reason you're not happy about how much better the house looks now that you're on the street. A truly YIMBY view of the world.

Will the people who can only afford to live in a "shockingly dangerous" neighborhood, after being priced out, end up in a less dangerous place?
