73 Wh/kg is a decent number. IIRC the previous gen Prius had 46Wh/kg batteries.

Perhaps with some reconfiguration it would be possible in the future to give those old machines some additional oomph, as the discharge limit in their NiMH battery packs is way below the combined power of the two motor-generators(21kW vs 60kW).

My startup runs and operates on AWS, and we were able to get off the ground with a tiny little team within days — something that would have once taken a large team of engineers and business development folks weeks or months.

I like to joke with my friends that AWS is responsible for the greatest second-order GDP growth on the planet, if you add up all of the market caps of all companies that have been able to build off of AWS (or their competitors). Rivaled only by MS Excel, as far as I'm concerned.
I wrote a couple of hobby projects with Solidity (Ethereum) years ago. At the time, I found the language to be ugly and amateurish at best. I'd expect any corporate project that uses such tools to eventually reach technical bankruptcy.

I hope you never experience America’s “due process.”

You thinking highlights your own inexperience. The system idd as heavily flawed and often makes mistakes. Many convictions are eventually thrown out. And that’s the very imperfect justice system. Don’t get me started on very imperfect software or data management.
The major problem with the return system for this is that it's great and easy, until you hit some of the anti-fraud systems and your entire account is at jeopardy, :/.

Google Docs is intentionally pretty bare-bones. You get features in LibreOffice like:

- text boxes in Writer

- vector graphics support (pdf, svg, ...)

- LibreOffice Draw, which there really isn't any equivalent to anywhere (it focuses on both drawing and text, while most vector drawing apps generally suck at text while Draw doesn't)

- higher performance with very big spreadsheets ("this should have been a SQLite file")

- Self-installed fonts

However, I do typically just use Google Docs when I don't need any of those. The recently added autocomplete feature finally did it for me.

I think they have a lot of users in Africa, Eastern Europe, places like that. If you look at their blogs they also have contributors there and focus some outreach there I think.
Yeah even if they pivot to be a completely different business model, no massive influx of cash is a bad massive influx of cash. Many companies would kill to suddenly go from death spiral to multi billion dollar.
I was going to add that he was relentless with his employees as well. I had a kid and was expected to be on call with a newborn, after spending all my vacation because there was no parental leave. Getting paged at 2am with a tiny baby is terrible.

I was repeatedly told that working on games outside office hours was not allowed, then later was permitted but only if you were willing to give Amazon all related IP. Oh, and you could not collaborate with people outside Amazon, so no game jams with friends.

To say nothing of the treatment of workers in the FCs, relatively low engineering compensation, etc.

I was building a social gaming destination which tanked.

The idea was to have a bunch of games (casual + social/party) and a bunch of friends in one single place. And also have all the banter that happens around these games, especially the social/party games, in the same place. So even if you are not in the mood to actively play, you can just participate in the banter which is also great fun. Better than commenting on photos, at least.

While the gaming destination as a whole did not work out, people enjoyed playing the social/party games we built and they led to a lot of banter.

So when we were trying to figure what next, we thought why not bring that banter to the workplace? While remote work is great, a lot of the team bonding/camaraderie that happens through random chitchat is really missing. And we thought social games are a great way for teams to socialize and build camaraderie.

So here we are. Bored brings social games to right where you work - Slack.

Would love to know what you folks think of it.
I play with fake money, in a Discord server with a bot we made and a few friends. Sure, I'm probably not the norm, but I find them useful :).
If setup correctly, the hosting provider ought to be incapable of decrypting the photos.
Is movement around the world a lot easier nowadays than 25 years ago? Remote work for example is a big thing, many companies are more multinational.

So you could just leave places where people are allowed to exploit the commons and move somewhere with a better working system.

Some cities would notice that they are not attractive places to live anymore and perhaps might want to do something about it.

It even applies if you work for someone else in my experience. The link isn't so obvious in that case. But I've written several books (both independently and though a publisher) and I'm pretty sure it's been reputationally valuable even though I've made very little money directly.

Writing a book alone isn't enough obviously. But it still sets you apart from others.
No kidding! My biggest fear was that I'd be dealing with the Google Support Blackhole. Thanks so much for the link.
How much do you make though?
Not pedantic just confused, I've never heard stock index futures referred to as commodity futures, that's all. If you told me you're a commodity trader and all you trade are stock indices I'd be puzzled. But maybe that's just me.
Honestly it isn’t too hard to hit the front page with something polished that’s of interest to hn readers.

I have not had anything to market to HN, but I’ve hit the front page with articles of my own a couple of times, with an ask HN once or twice, and with submitted articles at least twice.

The most popular article I wrote here was about how I tried not having home internet for a month (didn’t work, but was interesting). How can an article like that not hit the front page? You see 2-3 articles a day on that theme: wacky personal experiment + earnest well written personal narrative.

Not everyone can do that but it’s hardly some unique alchemy. If I’d done it once I’d say it’s the jackpot but it’s happened often enough without special effort on my part that I think anything reasonably interesting has a fair shot.

Assuming the submitter is a HN user, knows the community, has a track record of writing stuff people like, etc.

I’m pushing back because I think presenting fairly pedestrian accomplishments as jackpot level achievements has the effect of discouraging people from trying.

Obviously not everyone can write well enough to pull that off but most people making a course ought to have that kind of communication skill.
This article feels pretty disingenuous in a number of different ways. To avoid posting a wall of text, I'll summarize that The Atlantic is creating a narrative about what the narrative was, that way they can act like serious adults while just feeding us their own narrative.

The media was caught on their ass with this story, but never fear The Atlantic is here. With a big dose of Captain Hindsight who knows things that weren't public at the time to trash talk people speaking at the time. To insinuate everyone investing was a dolt that didn't know stocks go down too. And to reassure everybody that the retail investor should never be trusted with anything sharper than a index fund, that there is no takeaway about the market to be found here at all, and we should only worry about pushing politicians for more income redistribution.

Ask HN: How to build minimal login and payment for web app?
What is the easiest way to build a minimal product that has a way to have users sign in and pay a monthly subscription? Let’s say we want to do this in Python. To make this more concrete suppose I want to monetize a function hello(name) that takes a string and prints out "Hello, " + name + "!". What is the easiest way to build the subscription and payment infrastructure? Is there a SaaS that solves this problem?

I'm biased, as a fan of stadia, but I don't think Google will kill Stadia, at least not soon.

They're closing their game studios, which so far have produced nothing anyway. As a platform to play games, it's basically faultless. Consolodating the product to play AAA games without having a buy a console seems like a solid move.

I might be wrong. Google might do a Google and shutter it though.

It isn't. One of the reasons why e.g. the stock market is so huge is that participants rarely need to trust each other as the guarantees are provided elsewhere. Imagine if every buyer had to trust every seller (and vice versa) on every transaction.

The cryptosphere is trying to push a populist narrative for cryptocurrencies. Calling it the people’s money or democratized banking.

This seems doomed to backfire when people realize that the vast majority of crypto is held by lucky early adopters. A hypothetical Bitcoin dominated economy would be nearly the polar opposite of fair or democratized. I expect the populist angle to fail as people catch on to the incentives of early adopters, both private and institutional.

It's not a monolith like the capitol insurrection was and you're conflating the riots with the protests when they are two different things.

When the protestors were outside hearing the president speak it was a protest. When they tried to storm the capitol it was an insurrection.

There are clear, easy lines to be drawn. People don't draw these lines though because they want to further their political agenda.
Looks nice! Apologies if this is a very naive question, I'm not well versed into satellites so the only thing I can think about is Starlink. Will there be any light pollution? If so, how do you plan to address it?
Pulp fantasy started before Tolkien, Howard and Burroughs are more important for that genre. Tolkien is what took fantasy out of the pulps and started the hard cover doorstopper fantasy series.
Mac Lane was one of the founders of category theory - see for example:

"General Theory of Natural Equivalences" - Samuel Eilenberg and Saunders MacLane. Transactions of the American Mathematical Society, Vol. 58, No. 2, (Sep., 1945), pp. 231-294

His "Categorical algebra" paper from 1964 is open-access:

https://projecteuclid.org/euclid.bams/1183526392

When his book came out it was the standard work for a while. I think some of the terminology he uses is no longer standard, and there are now many very good modern introductions. But his book is still a pretty good read, primarily because he was a wonderful writer with a very distinctive style.

That said, the examples (given the time the book was written) are almost exclusively mathematical. The proofs and exercises are usually not difficult, but at a high level of abstraction (not surprisingly).

is reasoning out of anxiety always avoidance and hoping that what makes you anxious won't happen?

for me reasoning about something that made me anxious means to find the positive things that i can do if that thing does happen.

if i miss the deadline, then the pressure is off. it's only money, i'll need to reduce spending but i'll survive. the customer might cancel their contract? well, at least i don't have to deal with that jerk anymore. actually, why don't cancel the contract?

in other words rationalizing is to realize that X is not as bad as i think it is because or Y. not that it can't happen, but that it will happen, and that i can deal with it.

now i got a plan how to deal with X and so now i no longer need to be anxious about it.
Just in case you weren't already aware, you can hold Option when you click on the green + and it'll Zoom instead of going full screen. I'm the same way as you in that I don't really use full screen too much but I can understand that most people prefer their browser and email and stuff in full screen so that being the default makes sense to me.
Many sites didn’t do this right even large ones and often browsers if my memory serves right automatically put www and .com on any single word typed by default. That said yes, that should have worked, I just remember it not working enough that it wasn’t a normal or expected UX pattern until Google and maybe even Chrome.

You're saying that all road users, even pedestrians and cyclists, have to obey the highway code. But the parent comment never stated otherwise. They said that only certain types of vehicles need to be licenced. They seem to be referring to road tax, rather than MOT which is closer to a licence, but either way they're correct (albeit being a bit pedantic with the GP comment).
From the first statement, the "price" refers to performance implications. So the second refers to that too and the article mostly talks about performance.

Pure FP generally scales well with caching/memoization, because functions are pure, and with concurrency, because data is immutable. However the paradigm typically allocates more garbage and often creates more indirection due to its declarative nature (think function composition/pipelines/laziness and so on). So it is not as suitable for fine-grained/low level optimizations as imperative programming.
I've never run into this, because I never explicitly pass an expression when I want the default parameter value to be used.

You could just as easily run into a bug with 3rd party lib code by distinguishing between the two when that library doesn't.

The only reason I've ever intentionally used `null` in my own code is that it precedes `undefined` in the default array sort. But if I ever found myself using library code that required `null` for something, I'd say "Huh. That's weird." And then I'd pass it a `null`.
That’s more a symptom of the lifestyle of any popular software project than it is an example of it being a winning business model.

Time and time again you see these big monolithic applications get displaced by newer more focused applications and people love them because these newer applications run faster / is easier to use / etc etc. Then as those applications gain popularity new features need to be built to continue growth. Whether it is through feature requests, to fight off competitors with other features, or just the businesses way of finding new ways to look individuals into a walled garden....soon this focused application becomes yet another behemoth that people start to moan about. Eventually something new, shiny and focused grabs the public’s attention and we flock to that like the fickle herd of pack animals that we are.

Whether the Capitol protesters had a legitimate grievance is one matter, but if what they believed was in fact true, making the politicians that enabled it afraid for their safety is in my mind a good thing; those in power should fear that, if they abuse their power, and the people can't redress that wrong in any other way, e.g. through the courts, they may resort to force.

Again, I don't believe the protesters were correct, but they believed that widespread election fraud was being ignored by their representatives and state and federal courts. In their minds, resorting to force --- fairly mild force, in all honesty --- was not an unreasonable step.
I’ve said this before and I’ll say it again: blockchain’s killer app is creating trust where there otherwise wouldn’t be. This is similar to how RSA enabled trusted security/communication on an untrusted network.

Applying blockchain to situations where trust already exists is a waste (maybe a great learning experience, but provides no other value).

Right, authority-less blockchain is only intrinsically trustworthy for purely digital goods. If you want to track software licenses it might work (although 99% of the time a centralized solution will be simpler and vastly more efficient).

And this immutability can arguably be a detriment. Laws and rules are messy and can be exploited, not having any recourse if you get scammed is not necessarily a huge pro.

The whole idea that you could import all the rules, laws and regulations of the real world into a computer program without any bug or unforeseen issue is probably one of the most ridiculous aspect of that whole blockchain industry. Especially since we already have a fairly consequential list of "smart contracts" that have been exploited in the wild despite being fairly basic compared to IRL regulations.

"Oh you lost your house because somebody found a weird edge case between two smart contracts that let them buy it for $1? Ah man, that sucks, but then THE CODE IS LAW so... Tough luck. Maybe try buying DOGE coins? I hear it's gonna moon soon. They used rocket emojis, so you know it's serious."
> My binaries work on six different operating systems. In order to do that I had to roll my own C library.

Other people have made software for decades without writing program-specific libc instances. Tell me you at least started with something decent like musl instead of literally writing your own libc from printf on up.

> Linux should not be putting anything into the address space that the executable does not specify

Execution has to start somewhere, and kernels have often reserved parts of the system address space for themselves.

> The main thing dynamic shared objects accomplish is giving upstream dependencies leverage over your software.

Loose binding in interfaces allows systems on both sides of the interface to evolve. If you want 100% complete control over your system for some reason instead of writing programs that play well with others, just ship your thing as a VM image and be done with it.
IBM can hire and outsource most technical blockchain development anyway, so the I'd argue the company only needs a product manager, a couple of sales engineers, and an engineering manager to run the outsourced teams.
