Hmm I don't get it. They were a bit flippant, but they were just venting frustrations. Based on context, it seems they want to keep schools closed for safety reasons and got a lot of push back from parents.

Here's Paul Graham saying almost the same thing in 2003:

> And as for the schools, they were just holding pens within this fake world. Officially the purpose of schools is to teach kids. In fact their primary purpose is to keep kids locked up in one place for a big chunk of the day so adults can get things done. And I have no problem with this: in a specialized industrial society, it would be a disaster to have kids running around loose.

Oh man, I had the exact same thought.

"Really cheap" in the short term perhaps. Very expensive in the long term.

What price do you put in the extinction of a species? Millions of years of evolution flushed down the toilet so one person can have their disposable water bottle.
While redundancy makes it a moot issue, if I am not mistaken, 777s already use some of the most powerful engines available. As for how fast they fly, I believe it is mostly set by the speed of sound.

I wonder if we see a rise in ADHD in kids nowadays because it is an increasingly useful adaptation to our environment.

"Hyperfocus is the experience of deep and intense concentration in some people with ADHD. ADHD is not necessarily a deficit of attention, but rather a problem with regulating one’s attention span to desired tasks."

I don't know, but "hyperfocus" on a hobby you love sounds exactly like what most people need nowadays to get off their phone and stop wasting their life staring on ads and ad-financed content. Also, I remember that most things we covered in school were completely irrelevant for the real world. So a difficulty to concentrate on school stuff may actually be better than doing the homework.

In short, ignoring what society considers normal and instead being super focused on your own things ... sounds more healthy to me than the average "normal" person.

Pay teachers much more money. Make it easier to fire them for underperformance.

Provide better support systems for poorer families - childcare, healthcare, food security, physical safety, and so on. Children from poorer, stressed-out families tend do worse in school.
Cheap to produce. Infinitely expensive in the long term.
I think I addressed your second point above; for the first one, I think the ham community is largely gone at this point.

As you note, there are something like 700,000 licensed people in the US, but if you tune in to your local repeater and listen for a month, you will hear the same 2-8 people, typically in their 70s - and that's about it. They're there due to force of habit, and when they die, they're not going to be replaced. The same demographics can be observed for most ham clubs, maybe outside the SF Bay Area (where the median age is closer to 50).

So what are we really protecting here - a "community" representing and speaking on behalf of maybe 0.1% of all licensed individuals? Is this something to treasure, or should we bite the bullet and instead encourage a larger group of people to build something new?

And I hate to say this, but I think this situation is of their own doing. The old-timers wanted all the newcomers to follow in their footsteps and get excited in exactly the same things. As evidenced in the community-developed ham exam, which deals with such exciting and timely topics as tuning vacuum tube amplifiers, receiving analog slow-scan TV signals, memorizing Morse code shorthands, and DX contests that lost most of their "oomph" when the Internet showed up.

Meanwhile, VFH / UHF handheld-to-handheld messaging is still an elusive technology, and many old-timers don't consider anything above HF to be "real ham".

Ask HN: We need a calendar but don’t want to code it. What’s a good alternative?
We are working on an app right now. It needs to have a calendar and scheduling functions, but it’s not the main function of the app, and we would rather just drop in a configurable component rather then code it from scratch. The app is PWA, with React front end and NodeJS backend.

Any recommendations? Ideally we are looking for something that would allow us to store data in our own DB and also would be nice if it has a drop in front end for react.

Good point. Edited my comment to add that :)
Debian successfully packages a ton of Python software, notorious for its complicated dependency graphs. Has been for decades.

Debian packages a noticeable amount of C-based software which is just old. Emacs, for example. I suppose that skipping major versions (25 to 27) is considered unacceptable, and packaging and maintaining several versions is just proportionally harder.

(This is why my laptop now runs Void, and I get a fresh Firefox next day after the release.)
Yes they use two of the most powerful engines... and just one of those is more than enough to fly the plane just fine almost as fast as they are allowed to... so why else would they have two of them if not redundancy?

Fundamentally people can look it up themselves - 'ETOPS' - the redundancy requirement is a written regulation.
Apologies for my brevity, but that was my point. The author’s foregone conclusion appears to be that since his conclusions are bad, so too must be his reasoning; rationalism is rhetorical by nature, so deconstructing it this way isn’t going to convince anyone who didn’t already agree.

I’d love to see a takedown of some of those linked and earnest statements - though I suppose folks can be close-minded about “facts” as well (statistics can’t lie, right? /s)

I don't think you understand my point.

While I don't think I am exceptionally good, I am not a twenty two years old junior. I have a MSc in Computer Science from a (very) good university and an actual engineering degree. I can debug. I was developing real time simulators of complex networked equipments in a safety critical environment. I (thankfully) wasn't doing CRUD business software.

Let me illustrate my point with a story. I once spent three days trying to understand what wasn't working in some random network code in Ada using gdb and tcpdump because I wasn't allowed to install wireshark on these machines. In the end I realized there was a massive bug the version of the GNAT standard library we were using. Sockets were always bound to all addresses rather than the specified ip. I then had to write a work around because we absolutely couldn't update. And you know how I felt after that? Not clever. I felt sad, bored and like if I had forever lost a week of my life (which I had actually). Thankfully the project became bigger not long after and from then on I was able to spend more time managing the team and the project and didn't have to code much anymore. Gosh I hate coding.

My points regarding maths is not that you can't do mathematically oriented programing. It is that there is far more interesting problem in pure maths that have nothing to do with computers.

Nowadays, I work in management consulting on problems I actually find interesting and which thankfully involve more people than machines.

I was just sharing to give some perspective to the article. Some people actually deeply dislike programming.
I have ruminated about the same topic as the author on immortality, society and children. My take is that as a society we may at some point establish a system where people can decide between a) Living forever and b) Have children.

In Biology there is this principle that all living organisms push to remain either by longevity or reproduction. We humans have gotten very good at longevity and if you think about it as a society we are focusing on that path.

Now with the COVID19 event, I have thought that, if the same serious focused research effort, time and money was put by humanity on aging/degeneration/death related issues, we could have amazing progress in very little time. But for some reason showing relevant ads and paying faster is more important.

Unfortunately we are focusing on "living faster" instead of "living more".
The regulations have been shifted but only time will tell if it should be shifted. I guess we'll find out in 20 years.
That's no enigma. enigma had 3 or 4 rotors. This is more like a "tunny", almost. Germany's teleprinter encryption, what you hear about that was decrypted at Bletchly Park, was a machine that had 12 rotors. This picture looks like a machine with 10 rotors.

TL;DR: this thing probably has significantly stronger encryption than enigma.
China is already a big player in the RISC-V space and will likely dominate there. Ironically, this is at least partially due to the policies of the previous US Administration which is driving China to adopt the open RISC-V ISA so that they're not frozen out of US technology. But still, these are large players with a lot of money (gov funding in China's case).

> There are big players capable of opening it up like Philips, Sony, IBM, Microsoft

You forget Apple which with the M1 has proven that they can even outdo Intel. But again, Apple has a lot of $Billions to throw around. Microsoft seems to possibly also be making some processor moves, but we'll see how that works out (and again, $Billions to throw around)
This used to bother me, but it doesn't anymore. Somehow, I got over being bothered by wool's scratchiness, and even began to see it as a good quality.

I think this is an unintended consequence of my meditation efforts to dissipate my annoyance reaction.
So why the second boot option was not mentioned here[1] nor there[2]?

Mistake, I presume?

I've got my M1 Mac not booting because of the bug in Disk Utility and I really could've use second boot option. It would've saved me from the effort to reach 'another Mac' endangering myself with COVID exposure.

Why did the adults fail? Arguably because they weren't taught any better when they were children themselves.
Wonderful use of the word venerable.

Well once they've already fallen there's not much more to it.. It's not like it's a continuous stream of debris coming from somewhere. But it does look dangerous when it would have first fell though.
Thanks for posting this! I first ran across this quote in the intro to SICP, and didn't think much of it when I first read it (~2004). In the intervening years, I'd forgotten about it. I ran across it again a couple of months ago, and was surprised at how strongly it resonated. I've picked up Racket programming on the weekends to bring myself back to some of the fun that got me started in the first place.

Incidentally, Epigrams in Programming[0] is also an ongoing source of inspiration for me. I understand them in new ways as I get older.

...And once you walk a bit in their shoes, you realize they're equally pressured. In the end, they are neither dicks nor assholes, they're just clever enough to see that corporate words have no meaning, and maybe they turned a bit cynical because of it. And certainly, if their own boss is bullshitting them and their reports can read their bullshit, why should they be the ones taking the hit?

Bulk shipping to asia in particular is very cheap due to the volume of empty containers going in that direction. Not sure about other places.

Countries that recycle plastic have people pick out the good bits cheaply in hellish facilities, profit off selling the high grade recycling, the rest is "waste waste" to be gotten rid of somehow. Dumping it in the ocean is quite cheap.

The sorted plastic used to be a thing that you could mix with virgin plastic to get a cheaper product.

Since China's waste import bans, I believe it's actually more expensive than virgin plastic, partly because it costs more to produce now and partly because demand is driven by manufacturers who want to have a certain % recycled plastic in their product for marketing reasons.

The higher price incentivises other countries to import and process mixed plastic waste instead. They of course will also have to find a way to get rid of the not-useful portions of mixed plastic waste.
So, as someone that knows many teachers, and hears about how affluent parents especially will come in and demand that their child, who earned a C, should be given an A.

When the grade doesn't matter, what more are they, than "baby sitters"?

Now obviously, schools provide MAJOR help to especially poor kids, as a place to eat, shower and potentially get an education; but, when it's very rich parents who are able to work from home, and they're the ones demanding that their kids go back to school, so they can be alone ... what more are the teachers for them, than baby sitters? And, don't the schools have the right to be upset?

We've almost got the vaccine out to everyone. Regular school can probably return Fall 2021.

edit: the down-votes and complete lack of comments in response to what I've said are fascinating.
It's a shame that the lunar gateway is useless and itself a jobs program like SLS. Since NASA decided not to fund the version of the asteroid retrieval mission (ARM) that included de-spin there are no near earth asteroids that can be brought back to the proposed space station. All it can do is uselessly orbit the Moon, getting full cosmic radiation dose instead of less than half in Earth orbit in the magnetosphere.

In terms of resources the moon itself only has water. But it's down in a difficult to access gravity well. There's no nitrogen. Far, far, better would be fully funding ARM and starting to despin and drag asteroids to the lunar gateway for study, resources, and eventually living space in space protected from radiation and, if you build sub-surface tracks, enough acceleration to live normally.
I think it's the sunk cost fallacy. Nobody likes to admit they were wrong, even if it couldn't have been predicted when they made the initial decision. It goes double for politicians who not only lose face, but lose political capital as well.

SLS stopped making sense years ago. They need to cut their losses now.
Not the person you're replying to, but "steal" has been used in that sense for a long, long time—also long before the internet—e.g. "stealing ideas", so arguably it fits the definition just fine.
The stream of nonsense with which you have replied to me with, of course - and maybe you know it is nonsense, as you have stopped trying to defend it.

At this point, it would be better for you to acknowledge it is nonsense, rather than give the impression that you still cannot figure out that it is.

If we talk about US I'm unsure about that. Specially the first part of that statement, it seems that at least one of each three Americans are obese.

The best part when _again_ some people studying _put very important thing for the public interest here_ ... is done by volunteers spending their own money.

IMO, this moved forward with Linux at the OS level 20 years ago with apt and rpm.

Seems like now that hyper scale cloud vendors are displacing distros as gatekeeper, we’re going down a road towards niche packaging for languages, frameworks, etc.
It would really help if Boeing and ULA could score some wins. They're having trouble competing on price, schedule, and quality. We need more than one healthy launch provider to maintain competition.

Covid-19 vaccination: Find out if it’s your turn (California)
304 would be fitting.
Thank you! I subscribe to the Nature email newsletter and really like the book reviews they've revived relatively recently. Last week I stumbled upon the Science book review blog and thought it would be amazing if more journals did this type of general interest book reviews, and if these reviews could be aggregated for easy browsing. There are plenty of outlets for reviews of literary nonfiction, but not so much for popsci-type books in my experience.

I started with those two sites, then found the LSE one and reviews.ac.uk (a history book review site which I have yet to include). IEEE spectrum also has a book review section but it's very sparse, so I didn't bother.

I always thought of the logo as a lightening bolt, but looking at the thumbnail it’s clearly a W.

Back in the day it was an incredible tool, allowing you to target so many environments. Too bad it imploded onto itself.
I think it is just a matter of functioning at one's peak efficiency and health. I have experienced that state when I abstain from all the things which tend to drag down my state, including but not limited to processed foods including anything with added salt and sugar, coffee withdrawal, dehydration, inadequate sleep, lack of exercise, unchecked negative thinking.
> it's so often done

The MD-80 had two rear engines and was a fairly popular plane. A lot of smaller jets still have rear engines, too.
What a movie, I chose it randomly on an airplane, without ever hearing about it, and I think at the beginning I was thinking about switching to something else but I didn't and then I couldn't... took me by surprise how much I liked it. I don't know why, it's the first time I'm seeing it mentioned on the internet and I had to make a comment.

recently, my elderly dell inspiron laptop (think; windows xp) spontaneously ignited. It was switched on and i was in another room when i heard it explode. I returned to see lots of fumes and flames. Thankfully there was little loss of property. I understand that this is a known issue with dell. Is there anyone here who can explain how such a dangerous battery passed qc and the regulators, and why there is not more awareness around there issues?

That specific plane will go through a lot of rebuilding, checks, thorough investigation, etc. Given a choice, I'd take that plane over another one.

I expect the person interviewed is a pilot?
You'd be surprised. Years back, I saw what looked to be a near midair collision, including a smoke trail from one of the involved aircraft, and watched for a while from the front right seat of the Jeep my boss was driving us to a job site in. Presence of mind isn't really an issue. You're more just trying to understand and follow what you're seeing.

Today, of course, I'd be watching through my 500mm lens and taking pictures all the while. This was long before I got back into photography, though, and long before you could get a 500mm tele that didn't cost as much as a car. Even so, it was interesting, not frightening - remember that the sky is a long way away, and so are most things that happen there, weather notwithstanding.

Never did find out what actually happened.
Not currently, but certainly in the future we’ll have opportunities that open up. Feel free to reach out - email in bio.
No, that is a false analogy. Device capacity does not determine device usage. It's about market power and not about device capacity.
Usually, yes, it appears. Maintainers of projects are generally pretty invested in getting their software into popular distros... and so they tend to follow the patterns that would allow that. (I mean, stuff like 'where do I put the binaries' is still often configured in Arch and other distros, so we're talking about stuff outside of that kind of thing. Most packages aren't complicated enough to require anything outside of simple configure flags.)
All the more confirmation that weathering exist on other planets.
I totally agree, but I think that first Boeing and ULA need to figure out how to earn those wins by improving their product.
This is an off topic question, but is Debian a good alternative to Gentoo? Over the last three years I'm assuming Gentoo is so low on resources that they are just removing packages left and right. Every few months my install is broken due to this.

The main reason I'm still with gentoo is inertia and I really like the tools and just the way things work. The problem really is the portage tree (basically the repo) which is become more and more bare as the years go on. For example, I miss eix whenever I use debian, apt-cache just isn't as useful. Also, having to use not systemd is a plus and a reason I won't use Arch. Any suggestions?
Not sure what you mean? I didn't say it was always done. In fact the point I was making was that it wasn't always done. I gave my own counter-examples. It's just when people look at modern planes they always see two engines and think that's the way it has to be. It clearly isn't.
