> Basically, nuclear fission is clean baseload power. Wind and solar are not baseload power sources. They don't really compete.

This means you don't understand how the grid works. California's baseload is ~15 GW while it peaks at 50 GW.

New built nuclear power is wholly unsuitable for load following duty due to the economics. It is an insane prospect when running at 100% 24/7, and even worse when it has to adapt.

Both nuclear power and renewables need storage, flexibility or other measures to match their inflexibility to the grid.

See the recent study where it was found that nuclear power needs to come down 85% in cost to be competitive with renewables, due to both options requiring dispatchable power to meet the grid load.

> The study finds that investments in flexibility in the electricity supply are needed in both systems due to the constant production pattern of nuclear and the variability of renewable energy sources. However, the scenario with high nuclear implementation is 1.2 billion EUR more expensive annually compared to a scenario only based on renewables, with all systems completely balancing supply and demand across all energy sectors in every hour. For nuclear power to be cost competitive with renewables an investment cost of 1.55 MEUR/MW must be achieved, which is substantially below any cost projection for nuclear power.

> These companies want clean baseload power, with no risk of meltdown, and they're willing to pay for it. Here's what Amazon has chosen

The recent announcements from the hyperscalers are PPAs. If the company building the reactor can provide power at the agreed price they will take it off their hands. Thus creating a more stable financial environment to get funding.

They are not investing anything on their own. For a recent example NuScale another SMR developer essentially collapsed when their Utah deal fell through when nice renders and PowerPoints met real world costs and deadlines.

> with no risk of meltdown

Then we should be able to remove the enormous subsidy the Price Anderson act adds to the industry right? Let all new reactors buy insurance for a Fukushima level accident in the open market.

Nuclear powerplants are currently insured for ~0.05% of the cost of a Fukushima style accident and pooled together the entire US industry covers less than 5%.

I don't feel <file is obscure. I've seen shell in that style from coworkers and from open source. Your value judgement against it might just be your experience, rather than something universal.
The underlying topic for this is that, most shells treat files/redirections as part of the individual commands and not part of the pipelines. Files should be sometimes treated as commands instead, they plug into the fds of a process the same way as commands do.

`cat x | head` attaches `cat x`'s stdout to `head`'s stdin,
`< x head` just attaches `x`'s fd to stdin.
In this way, treating a file like a "light-weight" command (light-weight because no backing process) makes more sense, `open x | head` perhaps

Though I will note that, in a way, bash supports this, as it has a modules system, and one of the pre-existing modules in the source tree is a `cat` replacement, through my lack of understanding of C prevents me from working out if its optimal

That's kinda nuts how adult people learned to trust some random algorithms in a year or two. They don't know how it works, they cannot explain it, they don't care, it just works. It's magic. If it says you cheated, you cheated. You cannot do anything about it.

I want to emphasize, that this isn't really about trusting magic, it's about people nonchalantly doing ridiculous stuff nowdays and that they aren't held accountable for that, apparently. For example, there were times back at school when I was "accused" of cheating, because it was the only time when I liked the homework at some class and took it seriously, and it was kinda insulting to hear that there's absolutely no way I did it, but I still got my mark, because it doesn't matter what she thinks if she cannot prove it, so please just sign it and fuck off, it's the last time I'm doing my homework at your class anyway.

On the contrary, if this article to be believed, these teachers don't have to prove anything, the fact that a coin flipped heads is considered enough of a proof. And everyone supposedly treats it as if it's ok. "Well, they have this system at school, what can we do!" It's crazy.

"but monster wiring harnesses are not so cheap."

They aren't needed when the lighting is LED. The wiring harnesses going to more modern headlights are quite thin.

"I always imagined that newer cars would have a single CAN link to an ECU [0] in back, and that ECU would control all the lights near it."

They do but some are moving away because of the total lack of security and ability to compromise the CAN bus through the headlights to steal vehicles - read https://www.autoblog.com/news/vehicle-headlight-can-bus-inje... for what's going on there. They're too cheap to actually spend the money on real hardening so they're moving back to pure hardware control in many cases.

Ilya Prigogine wrote a lot about this, see eg Order Out of Chaos. He won the Nobel prize in chemistry for his work on nonequilibrium thermodynamics.

Boltzmann had originally tried to prove that the second law is a mechanical (statistical) fact and several others tried as well. But Poincaré showed that those systems which, regardless of their initial state, inevitably increase entropy later on inevitably reduce it (his recurrence theorem). There are also in fact reversible processes in nature, so it can't be that mechanics alone implies the procession of time. Something more involved is going on.

Carlo Rovelli has also written a lot about the "thermal time" concept in his books.

My takeaway from them is that you can't really get time out of mechanics by itself (statistical or otherwise). In the same way that you can't get baryon asymmetry. It is intrinsically a selection principle on initial conditions.

> Some people insist that we should never use a cat

Rather, people argue against useless use of cat, which is different. Personally, I'd never argue against it on the command-line even though some do. It's once you commit your pipeline to a script where you may as well remove it.

There are also suitable uses of cat that I don't think anyone would argue against. Besides the obvious use of outputting one or more files, it's also often used with here docs.
Warning uBlock Origin does not like this site!
The logic of the author's argument seems rather convoluted. To me, cat or not is a simple decision: does the first useful command in the pipeline accept input from a file, or only stdin?

I vaguely remember reading about numerical precision issues in Julia from this old blog post here - http://web.archive.org/web/20150226121144/http://wizardmac.t.... But honestly, it's from 2015, and Julia's evolved a lot since then, so it might not be an issue anymore. But I wanted to confirm, hence I added the uncertainty.
And if it were true, there is absolutely no way the Chinese government would allow it to be published.
Agree, with all in full sans the last one. Of course, if you're struggling, seek support.

We all have bad days or even bad weeks, life happens and often it's best to learn this. The current fad (?) of "I'm going to experess my non-positive feelings as they are all the time" gives too much weight to what are normal passing moments.

I don't want to say being a hypochondriac is normalized (else I might get canceled) but... Words, they create worlds. It's important to be mindful of what we choose to create.

Belief drives behavior, and when allowed to perpetuate the victim mentality can cause unnecessary (semi) permanent damage. It's perfectly normal to experience some pain. Don't make more of it than necessary.
You don't really need to imagine this though - generative AI is already extremely useful in many non-nice applications.

I used to develop Android professionally (at Dropbox in the 2010s, so I have some familiarity with older Android filesystem APIs) and made a very conscious decision to switch to devx and backend work and get out of Android (as did most of my former Android colleagues). The unending hoops you had to jump through and API changes to keep your app working were too much of a pain.

As a fun anecdote, in 2014 when the "secure" Storage Access Framework was new, I found a trivial directory traversal vuln that allowed writing to any app's private directory by just passing a "../../" file name to the system [0, 1]. It was so trivial I noticed it while just browsing AOSP source to understand SAF better...

Android also used to grant world execute bits to app folders for the longest time, allowing malicious apps to create hard links to other apps' files by name, which could then be handed back to that app for a confused-deputy attack to gain access to the file contents.

All that to say - I'm glad Android has been working on security, but it was built upon such a loose foundation that tons of apps used and abused that it's going to drive developers out of the ecosystem as they have to keep adapting to a continuous stream of major breaking changes as things are locked down.

To me this is like saying you shouldn't use a knife because they are also used by criminals.
Nope, AGPL actually doesn’t protect a bootstrapper from most of these problems. For example:

* If your monetization model involves a SaaS version of your product, VC-backed competitors can release open source code which extends your AGPL product in ways which compete with your paid SaaS. (The VC funding allows them to do things like this that don’t provide them revenue, and isn’t even part of their core product, but nonetheless takes market share away from bootstrapped competitors.)

* Or if your monetization strategy is open-core, then same as previous bullet, they can build FOSS solutions which reimplement your paid features just to take market share away from you.

* If your AGPL product contains novel techniques or innovations, VC backed competitors can copy those concepts without directly using your code. Free R&D for them.

* If your AGPL product involves a paradigm shift for how to approach a problem, you have to do a ton of outreach and education on how to use your software. Later on, newer VC-backed competitors can just piggyback on all that effort you already did. And then if you have any public customer testimonials, their marketers will directly target those customers.

These aren’t hypothetical situations by the way, this stuff actually happens. It isn’t just big cloud vendors doing it either. And no FOSS license protects you from it.

Some non-OSI "source available" licenses do provide protection from the first two bullets, by way of prohibiting competitive uses, but that doesn't help with the latter two bullets.

I used Syncthing for a while between various Linux distros, and I used Syncthing-Fork on my Android tablet, and it was okay when it worked, but it often borked up, and there were so many arcane settings and weird failure modes.

So today I just use Google Drive and MS OneDrive like a normal person. They work great. I love 'em. They don't fail like Syncthing. They're way more secure, and fully supported. Come join me! The water's fine!

> But it is suboptimal in the sense that it uses for loops

Looking at https://news.ycombinator.com/item?id=41897526 caused me to try asking for a solution in a language that doesn't have `for` loops. Since SQL was taken, I tried Prolog:

% Define a predicate to find all positive divisors of N
divisors(N, Divisors) :-
findall(D, (between(1, N, D), N mod D =:= 0), Divisors).

% Define a predicate to generate all combinations of three distinct elements from a list
combination3(List, X, Y, Z) :-
select(X, List, Rest1),
select(Y, Rest1, Rest2),
select(Z, Rest2, _),
X < Y, Y < Z.

% Define a predicate to find triplets (X, Y, Z) such that X*Y*Z = N
find_triplets(N, X, Y, Z) :-
divisors(N, Divisors),
combination3(Divisors, X, Y, Z),
X * Y * Z =:= N.

% Define a predicate to list all the triplets
list_triplets(N) :-
findall((X, Y, Z), find_triplets(N, X, Y, Z), Triplets),
writeln(Triplets).

Run:

?- [a]. list_triplets(108).
[(1,2,54),(1,3,36),(1,4,27),(1,6,18),(1,9,12),(2,3,18),(2,6,9),(3,4,9)]

I'm in love. I both understand what is happening (I think I would understand it even if I didn't know the task description!) and could easily port optimizations from the previous solution.

Maybe this is the point when being a polyglot developer - knowing tens of programming languages and their characteristics - will finally start paying off.
Indeed. An intuitive, easy to use oscilloscope needs at least to be digital and hence expensive. An alternative is using an electronics workbench simulator, but then again you might as well go fully digital.

When circuits become larger than trivial, the analog way is noise and temperature sensitive, you will spend a lot of time on tweaking those aspects by themselves.
That really depends upon the context. Many learn electronics in a classroom environment. Even for those who learn electronics independently, it has been possible to get new oscilloscopes that work at audio frequencies for well under $100 for many years. It looks like scopes that operate upto 20 MHz have been available for under $100 for a couple of years. They aren't great, but they are still powerful tools for learning.

And while scopes do take time to learn, learning about scopes themselves will convey a lot of fundamental information about electronics. I also wouldn't underestimate the difficulty in learning how to use microcontrollers. While using something like Arduino (boards, shields, development tools, and libraries) may be straight forward, the learning curve rises steeply as soon as you try to do anything truly independently. More steeply, I would suggest, than learning how to use an osilloscope. Besides, most of those development boards cost a lot more than a bare chip.
