> The largest birds are smaller than the largest mammals on land or at sea

With all my respect to you theory I think comparing size of animals should not ignore the medium they moved in: water, land or air. Weight is (loosely but still) related to size. It’s probably not a coincidence the largest mammals lives on water where they need less energy to supper their weight, and it’s not a coïncidents the largest mammals on earth are way bigger that bats.

The biggest bats are ~1.7m which is not so far from biggest albatros (3.7m).

Also consider the biggest bird (Ostriches) can’t fly. Now I’m trying to picture a swimming gigantic bird.
Makes sense. Let’s maximize the bullshit generation.
Did you ever forgot a cup of water somewhere? It fumed away after 2 weeks! All without boiling it. :-O
Same applies to lead, especially if you heat it to 360 C.
I have my Pinecil set to 320 C and it works beautifully for leaded solder. I momentarily bump it up to 400 for big ground planes, but rarely.
No need to wonder for long, just have a look.

> So taking a plain view, they're a hateful anti-human rights activist. Not sure why i'd listen to what an anti human rights activist has to say.

You are posting this in a thread and a story about Meta literally saying a certain class of people are considered second class citizens and thus it's perfectly okay to sling slurs and harassment at them.

You do realize this, right? Like you are saying that the company with zero morality telling it's users it's okay to harass people is better than the EFF calling them out. Like if you actually stand for human rights you should be horrified at Meta's actions.
Yes. In previous discussions it was noted repeatedly that 40% of websites use WordPress.

> If a business's operations are interrupted due to a natural disaster (or for any other reason) and it cannot productively use an employee, it is appropriate to furlough or lay off that employee until operations can resume.

1. Even in a logistics level, that's pretty much an abuse of "salaried" positions. Especially exempt ones. You get to suck out 60-80 hours of someone's time, but when they need to not get burned alive it's suddenly "furlough"? No.

2. A business that cannot survive for a few weeks without production is one that deserves to shit down. Individuals that don't have a savings is judged as unsafe, but companies can getaway with that behavior? It's a double standard.

>they can do that, but they are not expected to.

I'd definitely look up state laws about this one before spouting as fact. Federal may not care, but states have an incentive to not lose their entire workforce because businesses don't want to support the econimy in an emergency situation.
I think the book "The Bill Gates Problem" should be mandatory reading for all of HN.[0] Unfortunately, I'm afraid this requirement would backfire on me as I'm afraid that a ton of HN visitors would use it as a guide to become like Gates instead so they can too become a mini-dictator with unreasonable influence over the world.

American Prometheus, by Kai Bird and Marin J. Sherwin

It is based on ~20 years of research about Robert Oppenheimer, and is the inspiration for the movie Oppenheimer. Robert Oppenheimer is the scientist who lead the development of the first atomic bomb.

> Less interested in people and character studies. More interested in the mechanics of how things that we take for granted actually got built and what the world they were made in was like.

In this case, the "people and character studies" are very critical to understanding "the mechanics of how things that we take for granted actually got built and what the world they were made in was like". The early part of the book goes in depth to Oppenheimer's social ties to communist groups, which is critical to understanding the reason why he was forbidden from continuing research in the latter part of his life.

https://www.amazon.com/American-Prometheus-Triumph-Tragedy-O...

(To make a long story short, the American Communists, and their sympathizers, in the 1930s were blissfully unaware that the Soviet Union was an authoritarian hellhole. Many of the people involved in the Manhattan project had ties to those American Communists, and thus scientists in the Soviet Union. Because, for them, the Manhattan project was an academic endeavor, they wanted to share their results with their Soviet collogues. And that's how the nuclear race started... Information was leaked to the Soviets in the name of science. Oppenheimer was a victim of the resulting witch hunt; which requires understanding the "people and character studies" part of the book.)
That's weird, why does Stephen Wolfram gets some sort of special treatment here that nobody else seems to get - including people that are subject to much more common and intense criticism (just the other day there were people bitching about Trudeau, for example - or let's take Elon Musk who is an asshat (IMHO, YMMV), is discussing that off-topic when it comes to how he manages Twitter?).

The question "is Stephen Wolfram being taken seriously by the mathematics community?" seems relevant as a question to gauge whether one should spend time reading a very long article.

edit: an even more relevant analogy - is Mochizuki's big ego irrelevant in a discussion about whether his proof of the abc conjecture, that nobody understands and which he refuses to explain properly, is correct?
Public transit would also remove lot of jobs and yet nobody suggesting we shouldn't build more public transit because it will remove jobs.

I recommend realizing how crass your comments are. You won’t though which is fine by, there will always be a population on each side that is blinded by their own ideology. Discussion is valuable, finger pointing is cheap and is a lame method that both sides on the fringes use. There is a reason your comment is below 0.
You can model types as a set and sets as types in many ways, so a number of the basic set theory axioms are pretty simple to express as lemmas from type axioms. IIRC you get constructive set theory easy, but do have to define additional axioms typically for ZFC.
Ask HN: What is still hard to research in investment analysis?
I like to make investment decisions bottom-up, based on actual data rather than commentary. I don't mean algorithmic-trading, but taking strategic decisions as a human based on lots of primary evidence.

I've been doing it for a while for myself, somewhat isolated from industry standards. I would like your help to understand if there's a broader hunger for the techniques I've developed, a market.

LLMs have made it possible gather big-picture qualitative insights from scratch by analysing thousands public statements from companies: New/Upgraded Products, New/Upgraded Infrastructure, Strategic Direction and Commitments, R&D Initiatives, M&A and other Partnerships…

By finding common patterns and grouping them, by extracting structured features, categorising, filtering, aggregating, by relating them to each other, by enriching via automated follow-up research in other sources... One can get novel metrics about the concrete moats and plans of a company or a whole market, that are otherwise not available. Of course, this has been possible for a while, but it required training specialised Deep Learning models for every type of feature one wanted to extract. LLMs allow for much faster exploration without training, which enables modes of analysis that were simply infeasible before.

I've been wondering though: What concrete pain-points can be addressed like this for professional analysts? What categories of research still take hundreds of human-hours, even taking full advantage of all the modern tools and sources?
You could do wire wrapping like nasa still does; there will definitely be a high quality tutorial somewhere. Or if building a squashed bug circuit you could use crimps (with or w/o the insulator to be pretty)

I'm not one to nitpick tools to grok things but I think this could confuse more than help!

Because everything is relative to something else - and your example of the pendulum on a ship is suggestive of a "real" velocity, which does not exist.

I think a far easier scario to imagine is some ship flying away from Earth, and this ship has a magic button to release an impulse enough to give it a 10% of the speed of light boost in speed.

So what happens the tenth, or hundredth time that button is pushed? For those on the ship they would begin to observe (out the window) length contraction and of course time dilation - if they could somehow see Earth, everything would be in fast forward.

And vice versa, what happens on Earth? The ships observed speed would asymptotically approach the speed of light, but never reach it with its "apparent mass" approaching infinity, and thus the amount of velocity boost from each impulse approaching 0.

If our ship travels 20,000 light years in 40 years (from the perspective of those on the ship) then that would take a "real" 20,000 years from the perspective of those on Earth, who for many centuries would be able to track it moving away. If they somehow had a magic eye to look in the ship, things would seem to be going in extremely slow motion.

It's this nature of velocity (and dilation/etc) always and only being relative to something else that's really at the guts of all of this.
I still remember laughing my butt off at the elevator (or 'lift'?) scene from Small World at the time.

Ideally yes. And the limit is until things are stable.

But if you need a discrete answer, probably a few months? If we're in an emergency situation as a tech industry for more than a month, something much dire than business has happened. Many tech companies rebounded from COVID in a few months times.

Populations from hundreds of thousands to tens of thousands of people, over the course of millennia, in effectively completely egalitarian, likely communal societies.

And those are just the ones we’ve found.

Indus River Valley civilization may have been as many as 5 million people, no rulers, no social hierarchy, uniform housing, no monumental/elite structures or housing, no evidence of centralized power or government, standard weights and measures, collective infrastructure projects, etc etc.

It lasted roughly 1400 years.

So… no, you don’t actually need a small groups. You actually only really need it to be completely socially unacceptable for some to live in excess while others suffer.

In the entirety of human history, the only mechanism by which the human condition as a whole is improved is by applying a portion of the private surplus towards the public good. How much is a question of the moral character of the civilization in question.

In the 50’s, in the US, if you made over $200k (~$2.2million in 2025 dollars) you paid over 90% of every dollar earned above $200k in taxes. The top corporate tax rate was 52%.

A meaningless assertion? We've all been human and shared some values and ideals, even crafts and rituals. That's culture, for sure.

But we've always had clearly distinguishable systems, and seen as a whole then cultures have been separate and unique.

RP2350 maps RISC-V M/U modes onto AHB protection attributes equivalent to the v8-M combinations Secure + Privileged and Non-secure + User. The system-level TrustZone-M filters apply to both architectures, since they're simple bus permission checkers (plus some branding), and therefore don't care about the processor architecture.

Likewise the RISC-V PMP can divide M-mode and U-mode memory just like the SAU divides Secure and Non-secure memory; the SAU is just another layer of MPU. Secure/Non-secure interrupt targeting can be implemented by de-privileging an M-mode handler head into a U-mode handler tail, etc. You can read more about this stuff in chapter 10 of the datasheet (in particular section 10.6.2 covers the mapping of RISC-V modes to AHB bus attributes), but the short version is that the RISC-V cores have enough security features that you could put together a competent secure boot implementation.

Really this attack has little to do with the cores, and everything to do with the fact it is possible to bypass the guard reads in the OTP power-up state machine and read invalid values into the critical flag state. If the flag assignment had been different we would have seen either a different hole -- e.g. direct through Arm Mem-APs into OTP, which perhaps these journalists would blame on the Arm cores -- or no hole.

I really enjoyed 'How big things get done' [1], which is close to your 'how things.... got built' requirement. Very interesting read about delivery of really big projects.

And finally 'Build' by Tony Fadell but this didn't quite hit the mark for me as it was more a memoir about how great he is.

Well you have to draw a line somewhere. It's not evil to share your opinion to somebody who hasn't asked for it but there's a certain degree of amplification beyond which it's a problem.

The circumstances of evolution and the laws of physics have placed limits on how many people you can influence without help, so there's a handy line already drawn. The simplest way forward is to just use that line to define advertising.

Sure, the willingness to coerce transcends advertising, and I agree that exposing it in all it's forms is worth doing, but I'm a hacker not a priest or a politician, so I'm just trying to direct my efforts where they have a shot at being effective.

Koa is a backend API library and is independent of your SPA front end tech.
It is actually pretty common among Chinese companies. At least in Tiktok, where all software are internally developed (as explained in the article they use Lark, something similar to Slack).

This gives them flexibility and usability as different softwares can interact seamlessly. For example you can click open a link to the document that other people are screen sharing during a meeting. But it also embeds your name on the screen so you probably don't want to take a screenshot or a photo.

I know many companies also use techniques that generate invisible watermarks that are difficult to remove without breaking the image. I don't know exactly what the technique is, but maybe this is close:

When Norway Got Internet
There's considerable risk in that strategy if taken to the extreme. Because you could eventually outsource virtually everything, including critical dependencies, and then just be left with a sort of pure military-financial hegemony, but that can be a rather unstable equilibrium.

Not saying there's no tasteful way to stably approximate that state though (and even not requiring stepping on other's toes, which may actually help in combination with the right narrative).
Except he's not actually playing the game himself, someone else is boosting his characters up. It's been proven.

It’s interesting that in my reading of the post I felt like he hardly talked about Tesla at all.

He calls out that Tesla FSD has been “next year” for 11 years, but then the vast majority of the self-driving car section is about Cruise and Waymo. He also minorly mentions Tesla’s promise of a robotaxi service and how it is unlikely to be materially different than Cruise/Waymo. The amount of space allocated to each made sense as I read it.

For the meat of the issue: I can regularly drive places without someone else intervening. If someone else had to intervene in my driving 1/100 miles, even 1/1000 miles, most would probably say I shouldn’t have a license.

Yes, getting stuck behind a parked car or similar scenario is a critical flaw. It seems simple and non-important because it is not dangerous, but it means the drive would not be completed without a human. If I couldn’t drive to work because there was a parked car on my home street, again, people would question whether I should be on the road, and I’d probably be fired.

At Chaos Communication Camp (2023) I brought a hard drive to attach to a Raspberry Pi with a USB adapter, and a little solar power system because I could.

I realized the inverter was using about 5 watts idle and that was about half of my average power budget for the camp (counting night time), so I cut the adapter's cable and re-wired it directly to the battery. Worked fine. Most components in a computer that nominally run at 12V are passing it through some sort of adaptive converter (either a buck converter or directly to a speed-controlled motor) so they have a fairly wide voltage tolerance. I obviously didn't find out if it reduced the lifespan at all.
It's funny that people were once proud of the pragmatic origin story and now apparently ashamed.
