b) get folks to mention which chair, too. Some of us invest in ergonomic chairs, and those who don't would benefit from opinions on which chairs are good

For what it's worth, I got this chair recently (a Torch Iris Gold) in Hong Kong, and found it incredible value for money, at least compared to a Herman Miller Aeron, Mirra etc; : it has a bunch of adjustments that the Aeron and Mirra do not. Obviously, this advice isn't that useful if you're not in Hong Kong.

I actually have a ready-to-go DIY aquaponics plan using wading pools (HDPE) and PEX piping (no PVC), and two more plans in the works: indoor shelf system, and outdoor pond aquaponics system. If you don't mind, sign up for my mailing list, I plan to send out an email about aquaponics today: https://automicrofarm.com/.

The below forum is pretty much ground zero for the hobby in the United States IMO. There's some very very talented regulars there who are truly pushing the limits. All the owners of the electronics and software used in the hobby are on this forum too and post regularly. Many University teams show up on this forum too, i believe this USC team is there from time to time asking for advice.

Is that bad?

Someone wants to educate their children at home, in Germany that's not ok. In the US it is, so in the US they get some level of asylum.

These folks aren't some terrorists, they're not hurting anyone... seems like a situation where there are two different approaches, not some serious crime.

It also is a case by case basis so who knows if it holds up in court for long.

Edit: Looks like they lost the asylum part of their bid:

I'd like to think there's some nascent game developer out there that would think up something cool once they have their hands on a production piece of equipment.

You can't always lab-grow your most creative ideas.
You can do that job, and have it be enormously beneficial to your family, friends, and neighbors.

I've been looking for a resource like this.

I consider cooking a fantastic hobby, it

- provides an entry it lots of interesting scientific questions, both in food preparation and digestion/health.

- is a big money saver over a lifetime.

- is a great social activity with deep cultural roots.

As a programmer, I also enjoy the approximate and ephemeral nature of the process and product, similar to software engineering in some ways, completely different in others.

As mentioned earlier by dsr_, at 340km, a 1.5 degree beam covers a circle of just under 9km diameter. Let's call it 50 square km.

If a single satellite can cover a 9km diameter, I think it will be just fine for vehicles. Especially so as the idea is for overlapping satellites. Also, much of the starlink bandwidth will be used for extra cellular / wireless / internet backbone areas. Areas that need long haul fiber optics to have bandwidth suddenly won't, so it will actually improve existing internet service providers as well since their addressable market will increase.
RSA has known to be broken by Shor's algorithm since the 90s, as well as Diffie-Hellman and elliptic-curve Diffie-Hellman. The only question is how practical is an attack going to be, and how much time do we have to switch to post-quantum algorithms. NIST has been running a competition for post-quantum cryptosystems since 2017 (approximately 10 years late to the party) and we'll see where we end up.

I believe it is one reason why MPEG is working on EVC, a Royalty Free Video Codec based on H.264 with a target of 20% improvement.

Hopefully the industry as a whole, mainly Apple and Google can settle on something that is better than H.264 and JPEG.

Right now Google will not support H.265, and Apple isn't fully on board with AV1 yet.

A study analysing 36000 deaths and 3 million person-years (published by the American Heart Association) found a 21% increase in all cause mortality among those consuming 2 or more sugar sweetened beverages per day. Consuming 2 or more artificially sweetened beverages, on the other hand, was associated with only a 4% increase. And moderate consumtion of artificially sweetened beverages (< 2 per day) was actually, unlike sugar, associated with decreased mortality. [1]

How Remote Workers Should Build Their Online Presence
My comment above explicitly describes what I refer to as "official recommended maximums": the maximum daily intakes recommended by the AHA and WHO (among others around the globe), presumably through an audit by domain experts of the totality of epidemiological and clinical evidence, together with an unknown amount of interference from non-scientific interests.

To address your analogy, researchers are in a sense writing the Missing Manual for Humans, as our species didn't come with one.

You're free to accept or refute these recommendations, but I personally am inclined to put at least some trust into their collective efforts. Or if you trust different recommendations more so than these, I'd love to see them.
The UK has particularly frequent trains compared to its continental neighbours.

For example, there is a train every 20 minutes from London to Manchester (320km), but only one train per hour from Berlin to Hamburg¹.

This is part of the reason for the higher prices.

¹ There are slightly more, but they are slower such that it's not worth using them.
Unlike other commentators, this doesn’t make me feel bad about my cubicle job working on abstract problems.

It does make me sad about living in a sterile mega city with no form of community with my neighbors. It makes me miss the days I used to live in a much smaller town, in my home land, where everyone knew each other, and we had shared festivals, feasts and fasts together.

Thanks for sharing the twitter thread.

We used to keep a mixed flock of goats and Katahdin sheep. We got rid of the goats. The event that tipped us over the edge was when my wife was on a ladder trying to fix the gutters on the barn. One of the goats was watching her with a jaundiced eye. After she got to the top of the ladder and was leaning over trying to reach the loose gutter, the goat decided that was the perfect time to butt the ladder - attempted homicide of the shepherd.

But this was just the last event in a long line of offenses. There is a good reason why sheep are associated with righteousness and goats with wickedness in the Bible. Sheep treat each other with much more kindness than goats. When you feed grain to the sheep, the first sheep sees you, baa's, and the rest of the herd comes running. They jostle each other at the grain feeder but fundamentally everyone gets to eat. When you feed goats, on the other hand, the first goat who sees you will try to sneak into the barnyard without making a sound, the better to eat all the grain herself. If two (or more) goats see you, they will proceed to fight in order to decide who gets to eat first. They will do this every single day, without fail, the same fight over and over and over.

Sheep have a sociality. When it's time to leave the barn in the morning, everyone lines up single file, with the head ewe in front and the ram, if there is one, in the very back. The head ewe will take a few steps, stop, look and smell. Everyone behind her will stop and wait. She'll take a few more steps and repeat. The ram makes sure nobody gets left behind. Going a hundred yards into the pasture can take ten minutes.

We never found any sociality in goats. Sheep are members of a tribe. Goats are the ultimate individuals.
Huawei is a massive company with a large lineup of affordable Android phones. Why can't they just fork Android just like Amazon and Microsoft?

They could have a contact form with something along the lines of "click here to allow this agent to contact you", and then the affiliates pay for the leads.

My process with HN articles is

1. Find a topic that looks interesting or important based on the title

2. Read the top two comments.

3a. If they are incredibly polarized, read the article.

3b. If they are in agreement, just read the comments.
Well they had a vote already, so then with a do over precedent, do officials just keep asking for do overs until they get the desired results? It's messy.

I do think these high-capacity, self-driving-only tunnels are a great idea in dense areas, but the tunnels and the self-driving bits are the easy part.

The hard part is going to be the "vehicular multiplexing" that will be required on both ends to take a dozen or so lanes of traffic and squeeze them down into a single, compact, non-stop stream of vehicles through the tunnel. Otherwise, if you can't get ultra-high utilization out of these tunnels than they're really nothing more than a subterranean version of taking your personal helicopter to work.
If I listened to nutritionists, I'd eat 11 servings of bread a day and no meat.
Yes, and reason because the decoder was cheap to implement. Transistor isn't getting cheaper like it was in the old days. The complexity of anything post H.264 is much higher, which also meant higher transistor count, higher budget, and higher cost.
Haha, pretty good idea.
(US resident). I haven't gotten one piece of junk mail in nearly 15 years (except for a few generics addressed to "resident", but even they are uncommon). Before that it was weekly shiny newspaper type ads and letter spam by the pound with a tiny bit of real mail.

It was an accident but here is how I did it.

I had a temporary job back in early 2000's so I got a short term lease in a different city and opened a PO box at post office. Then I unexpectedly got called back and was slated to return but didn't and neglected to close the PO box and forward mail. I was a road warrior for next 5 or 6 years and seldom at permanent address, so I didn't bother putting in address change back to permanent residence. Instead I got an online mail service (I don't know if was this, but something like this https://www.postscanmail.com/) that opened and scanned mail and I'd read it in browser, download scans, and have important stuff physically forwarded to wherever I was at the time.

Finally that all ended and I got a real address and stopped the online mail receiving. For whatever reason something in that process completely stopped the junk mail to this day and it's wonderful.
This is all very depressing.

I got a kid on the way too, I need to reinvent myself.
Such behaviour is exactly what is causing me to doubt my long-held belief that all drugs should be legalised. I just don't know any more.
Oh, I see. I think maybe the boomers switched because of the convenience and didn't mind the cost, and then society forgot how to cook? Whereas here eating out a lot is very expensive, so we just didn't do it.
A microwave is indeed a very powerful kitchen tool, however almost nobody knows how to use it. People blast food at high power because they can’t wait 2 more minutes for a lower power cycle. To most people, a microwave’s primary function is to “cook” frozen/processed foods like TV dinners and burritos, which is exactly the type of food the OP article is talking about avoiding. You also absolutely cannot cook meat in a microwave oven and expect it to come out palatable (and if you just expect people to not eat meat you’re out of touch with reality).

So when talking about getting away from processed foods, it’s very helpful to also get away from the microwave, because people have such a strong association of the two things.

An oven can do it all. Once you accept the concept and master it, you then stop looking for shortcuts in other gadgets.
It was a design copy. More than just having a similar footprint, too. Going from memory, it was the same size, screen, bezels, home button, dock connector, charger, and came in a box that looked just like the iPad box, was advertised with pictures that were nearly identical (technically different, but same gender, same colors, same pose, etc). It was actually pretty hilarious at the time because it was so over-the-top mimicking all the way down to details that you'd think nobody would bother with. At one point there was a great web site that just put them side-by-side and showed all the detailed copying. But it's been enough years that that seems to be lost to the dustbin of history, or at least my google fu is not strong enough to easily find it.

Samsung doesn't do anything like that now, they've long since found their own identify for all the Galaxy devices.

When I was a kid we had a horse at a farm where they also had some goats. I can totally see the Brenda story in those goats. They have a talent for mischief and are very smart and brave in their own way. Definitely a lot of fun if you have the space so they can break stuff that’s not important . They also like to nibble on wallets and shirt. The nicer the better.
As far as the overall utility to harmfulness ratio, I'm sure cigarettes lose compared to those products. It's like comparing crack to cell phones. Yes, they are both somewhat addictive. However, one has demonstrable utility, and the other doesn't, even for narcoleptics.

The discussion of whether the use of state power to regulate products is appropriate is a potentially lengthy political discussion that isn't worth starting here.

I strongly disagree. The article describes in detail the student group's years of efforts to reach space, culminating in this success after years of failures. Moreover, they're the first collegiate team to make it to space (and the second "amateur" team).

> In terms of technology, what everyone looks for is a general understanding of software (architecture, algorithms, data structure, etc)

I'm glad to read that. I focus a lot on those aspects of the job, and I think that they are very important to produce good work. These are the aspect of the job I love most. Interviewers around here (south of france) don't seem to be interested in that. They tend to ask very specific questions about languages or framework instead.
I dont remember specialized software for medicine being exactly that cheap... But I see your point.
The idea of smart contracts or world computer is flawed. A better term would be a scripted financial transaction. They can be done in a trusted environment, but there are a lot of benefits of having a public cryptography secured ledger.

Though the article author omits it, EOS mainnet runs on LLVM and WASM contracts and executes about 1000tx/s today.

A more powerful financial VM is needed e.g. for on-chain order books.

It's a Chevy S10 that was spec'd with the reliable low power engine and a different body. It's not really anything special in terms of reliability. The post office simply committed to keeping them for 30yr then followed through. It helps that they were working with a purpose built commercial body and not an "engineered to a price point" stock truck body. Any other similar truck platform of the era would have fared similarly. The late 80s/early 90s were a time when the electronics of the 90s were coming to maturity but hadn't yet snowballed in sheer volume like they did in late 90s and early 2000s.

In any other context the internet would be all "hurr durr, GM builds junk, muh indestructible Hilux because top gear". Goes to show you how much reputation and framing matters.

In hindsight the best available platform of the late 90s/early 90s for sheer reliability (in postal use) would have been a 1st gen Explorer only because the front suspension is better suited to handling potholes and driving over curbs all day and the 31spl 8.8 rear axle is complete overkill for the application (all other differences are minor/negligible IMO).
You see the same principle behind people's Instagrams. People shoot, re-shoot and meticulously edit their uploads so they're as flawless as possible. I think Reddit has something called 'r/shittybattlestations' as a joke sub to counter the deluge of samey "minimal IKEA desk w/ hyper-expensive equipment" content on the main subs.
Correct me if I'm wrong, but I do not see any conclusion in that study that diet drinks are worse than non-diet drinks regarding metabolic syndrome (only that diet drinks might also be bad to some degree).
