My keto diet was chocolate protein shakes, protein bars, and powdered soups. New Direction it's called. 3 meals, 2 snacks a day. 128 oz of water a day.

It worked great as a way to lose weight. And for people who need to lose weight to prepare for surgery, I still think it's a neat program.

But I was just not equipped to survive returning to normal foods. And stress.
You forgot the key part of "for the first 3 months" the assumption is that they largely tapered off for OP I think. That's an easy trade off for me personally.
You get a warning popup and the application is blocked from running if it is not signed by an Apple Developer Account ($100/yr) and countersigned (i.e., notarized) by Apple.

This has been the case for over a decade. I've launched my first startup 11 years ago. I've used Linode and we've spent something like $20/month on hosting. (This has increased to around $80-$160 IIRC when we got funded, mostly due to the increased storage needs. We were a music startup and while S3 was pretty cheap back then too, it was easier to have everything on Linode at first. I.e. with enough funding, time was more expensive than storage.)

A bit more than a year later it went bust but I hoped I could still keep it alive, make it financially viable. I scaled back the infrastructure so costs would be below $30/mo again.
This is really neat, but not to be confused with Blink, the name of the browser engine underlying Google Chrome, Chromium, and derivative browsers.
> I am deeply skeptical of any such claim for the inside of a star because of the sheer amount of entropy constantly being jammed in by the environment. A star entity would be made of relatively normal matter (compared to some other things), even mediated through magnetic fields, and would be working on not entirely dissimilar time constraints from us, so it is difficult to see how that could work.

I am not a physicist but I think this is a moot point when the entire basis of the paper is string theory and requires the existence of hypothetical monopole particles to encode information like DNA. This is all sounds like wild speculation built on top of the most speculative theoretical physics still active in academia.

No, the Quest 2 has been out since 2020. The Quest Pro is the latest.

It's unfair because the Quest 2 is mainly a console and was never marketed as a productivity AR device. That's like trying to do your job on a PS5 and claim it's underwhelming, or take your Ferrari off-roading and claim it's underwhelming or trying ML workloads on a Gameboy and claim it's underwhelming.

You are are of course free to try those scenarios and have your opinion that the devices are underwhelming, but nobody can take your point seriously.
The problem is that we are plausibly looking at the result of a change over the last thirty or fifty year in the quality of what's considered the normal diet, notably normalizing calories through the consumption of sugary drinks but also a variety of other things. This has had the side-effect of an obesity epidemic.

Now, what are we doing?

* Getting people to stop consuming sugary drinks and other very unhealthy items (maybe that would require drugs at this point)?

* Or offer people drugs so this side-effect of an unhealthy diet can be avoided?

If we're offer a way to continue a bad diet without this effect, it seems very likely further bad effects will appear X many years from now from a combination of the drugs and the bad diet. Because virtually all drugs taken forever accumulate side-effects over since the body did evolve to process them (these drugs may indeed be needed at times but the point remains).
NYC does have a number of dedicated salt-spreader/plow trucks [1].

As for why they use garbage trucks to plow, I speculate that it's an issue of scale. Buying a special purpose plow truck to replace every garbage truck that currently does double duty would leave you with a pretty significant/expensive fleet of trucks that are sitting idle most of the time (not to mention taking up space, which is at a premium in NYC).

> they account for social service transfers

They claim to account for them. Whether they actually did so in any way that makes sense is not documented. Given the credibility of the source... ¯\_(ツ)_/¯

Also, their claim is "social benefits paid to households". That wording strongly suggests that they only took into account those social benefits that result in a payment, of money, from the government to the households, such as social security payments or unemployment benefits.

Which would miss the vast majority of benefits, including all the ones I mentioned, because those benefits don't work that way.
Why are they using garbage trucks to plow snow?

Looks, I get that I'm biased being in Canada, but do they understand that you can buy dedicated vehicles for plowing snow? They're called... snowplows. They're pretty fantastic.

You need garbage trucks every day, all year. Electrify those. You need snowplows on a handful of days per year- and that number is falling thanks to climate change. So buy purpose-built snowplows for those days that use fuels instead of batteries.

But it's silly to decide to have an all-fuel fleet of garbage trucks just because they can't also be used as snowplows a few days per year that you need them.
That’s pretty much what I said. People are comparing themselves with those around them. If they’re about equal, they’re happy. If the society has high inequality, they’re unhappy. The absolute level of what they have is irrelevant, which is weird. You’d think that a person who doesn’t have to worry about food, clothing, shelter, entertainment and social connections would just be objectively happy. But no, the existence of many rich people makes them feel worse.

This isn’t good or bad. It’s just the way humans are.

Let me introduce you to Matrioshka Brains [1]. It's not quite what you suggest. In this case it's one (or more) successive shells around a star to use the solar output into computing power. The amount of computing power you could get from this is simply unimaginable.

This structure would have similar properties (and honestly isn't really that different to) a Dyson Swarm. Assuming thermodynamics holds the only way to get rid of heat ultimately is to radiate it away into space. At any temperature you're likely to get to this is going to be infrared light. The wavelength of radiated heat is solely determined by temperature.

So could you instead radiate away visible light? Technically, yes. Kind of. One way is simply to use a lot less of the energy. Now could you get the temperature up to where this has a visible light signature instead? You're talking about thousands of degrees. What material could get that hot? It's a big problem.

Also, such a material will still have telltale signs. Spectroscopic signature would reveal it wasn't the expected hydrogen-helium mix.

Another possibility is a truly giant star. Stars can get incredibly large. IIRC the largest known star (UY Scuti) if it were placed at the Sun's position would be large enough to swallow Jupiter.

The thing is. These supergiants/hypergiants don't have a hostile boundary or surface in the same way a cloud from a distance looks solid. It would be hot but really diffuse. Technically it would be possible to build within the star's atmosphere and dump the heat.

They can sacrifice street parking spots systematically throughout the city for garbage dumpsters, as many others have suggested, but it's politically untenable to do so because americans love their cars, even in NYC.

Another politically untenable solution is to do what Taiwan does and force people to put out their garbage in very tight time windows and otherwise store it privately in their houses and businesses, but that is a unproductive use of human time on net.
Actually I am confident exactly because I do know how LMMs work, and your comment fails to address the issue at all. Such models can't tell you anything useful about the probability that a particular statement is accurate.
Too much of this thread is debating whether these drugs are a good thing or a bad thing, and not enough is on the underlying science story, which is what HN "should" be interested in. What's happening with these drugs --- that you can replicate much of the effect of bariatric surgery with an injection --- is super interesting, and didn't seem to be on the horizon 10 years ago.
Somewhat timely. AHK is one of those utilities I absolutely cannot go without. I've been running it on all my Windows machines for 15 years now.

Just a few days ago I was complaining¹ about how Excel handles formula input. After some back and forth on my yak-shaving attempt, I realized I could shave it myself with AHK.

Yeah but turn your signal producer into one that has less noise and find out that the world is noisy and entropy wins in the end and that people are just other systems inside the system and all of it has it's own goals.

And so why bother? Embrace correlation, seed the world with noise, burn yourself up as you and all of it burns down and we wait for the telomeres to do the inevitable.
Your belief in a fact is unnecessary. The issue with these studies is they don’t control for lifestyle and diet. The notion that you can not be fat while eating a high quality low calorie diet and exercising is simply false. A valuable study in this space would be measuring the impact of diet and exercise on health outcomes while holding BMI constant, then comparing across stripes.

In studies where diet and lifestyle are controlled for, metabolically health overweight are not at greater risk.

The issue is we are pointing to fatness and not diet and exercise. It’s causing people to seek ways to get thin assuming it’ll help. But some people are thin no matter what they do, some are fat. However there’s a correlation between poor lifestyle choices and being fat and good life style choices and being thin. This skews uncontrolled studies towards fat is bad even with good metabolic health, because having a good metabolic health but maintaining it with poor inputs will have a long term bad outcome.

In one of the reference below, the conclusion is:
(i) Higher fitness should be considered a characteristic of metabolically healthy but obese phenotype. (ii) Once fitness is accounted for, the metabolically healthy but obese phenotype is a benign condition, with a better prognosis for mortality and morbidity than metabolically abnormal obese individuals.

Disagree. People genuinely enjoy those foods, because they're tasty and flavorful. And there's zero reason to believe that they're substantially unhealthy unless consumed to the point of sustained caloric surplus. We know this because we have hunter-gatherer populations who consume 50% of their diets in sugar (e.g. the Hadza) or fats (e.g. Intuit), and they have none of the diseases of abundance found in modern populations because they have near zero obesity.

The problem is not the food. The problem is obesity. The food is only an issue because some people have overly strong appetites relative to the abundance of food. If we can cure obesity, then we can literally have our cake and eat it too.

Humans obviously value tasty and flavorful food, and its existence adds joy to people's lives. That's why they'll pay hundreds of dollars per meal for the best restaurants. In sum total the development of GLP-1 agonists has maybe cost $20 billion in research at most. That's literally less than 0.1% of global GDP, hardly an "enormous waste of resources".
I do calculations on Maxwells equations all the time, that's s calculus. Doing CAD, or any finite element calculations - > calculus. Modern engineering would not be possible without calculus. Just because software engineers mostly use linear algebra, doesn't mean that most other technical disciplines are the same.
Someone pointed out that the energy cost of training GPT is roughly on par with a single transcontinental flight. If so, I don't think this is a limiting factor in any meaningful sense - you could spend that much energy daily, and it would still be a drop in the bucket overall for any moderately large business.
WAL and synchronous=NORMAL is huge.

I love databases that choose safe defaults.

That said, many real-life applications of databases don't need to block for confirmation that the transaction has been durably committed -- ETL jobs, integration tests, most logging, etc.

They will send at least some visitors, which is better than the zero visitors you will get from bing if you block it.

Yes and microsoft has lawyers, who have presumably determined that the cost of fighting these frivolous lawsuits is not overwhelming.

Why use drugs and lifestyle changes when lifestyle changes alone will do the trick? Everybody knows you're not a real Hackernews until you adopt a cold, calculating, "food is fuel" mentality toward eating, with extensive data collection, strict timing, data-driven portion control, and long fasting periods. Once you do that you don't need the drugs and can tell Big Pharma where to shove it.
Snow is a rare enough problem in NYC (1-2 weeks in a year), and having a whole fleet of dedicated snow-removing machines is not reasonable.
Also it is much easier to pass those snacks and other stuff when you are full or not hungry. If this is consistent state, it can also effect how accessible at other times snacks and such are.
Well if you do it every time at like 2-3C, you’re talking maybe 500 cycles compared to 1000 cycles at a slower charge rate. Depends on other stuff, too. Depth of discharge and max charge voltage are both even larger effects, but it still matters. (Knowing the exact chemistry of your phone’s battery can make a difference here, of course.) https://www.mpoweruk.com/life.htm

Fast charging from, say, 10% to 50% probably is a fairly small effect compared to trying to fast charge to 100%.

Garbage trucks are probably one of the best places for it actually, because they stop so frequently. Unfortunately the article is about plow trucks instead which have a very different use case - New York just happens to use the same vehicles for both so they have a smaller fleet that's not as well suited to either task.

For garbage trucks you have stop and go movement so EVs eliminate idling. Given the size of the trucks it's probably not a big deal to make sure they have adequate battery capacity.

Plow trucks have a completely different use model where they're run at speed for long periods and one day of plowing could have the same distance traveled as weeks of trash collection. Hybrids would likely be an improvement in efficiency but the same way they do for other trucks - batteries support high demand periods while the generator is fine for the lower sustained loads.

Edit: a drawback of the smaller fleet for snow management is that garbage trucks aren't as well suited for salt/sand/deicer distribution. Nobody designs their garbage trucks to spray. I hope.

Edit2: garbage trucks also have a lot of additional mechanical systems that are probably already electrical, so among other things the ICE versions likely have an oversized alternator to power that.

Ask HN: Best way to learn DIY robotics?
I am a computer science person (programming, OSes). I would like to learn to build my own robots at home (e.g. a small wheeled robot with a camera wandering around). I am missing the knowledge of lower levels (arduino, circuits, motors, etc.)

What would be the best resources to learn this?

Thank you!
I like to think of this in terms of JIT and AOT for learning. Somethings you'll learn just-in-time and somethings you'll learn ahead-of-time.

It's a bit too far to say one is ruining the industry. I think you could however argue that it is robbing people of an education. Most people take the extreme of only doing JIT learning and that makes us lazy. Some people take the extreme of only doing AOT learning and they get nothing done. A balance is definitely needed.

I had one of these in the 90's! My father and I put it together, got it working and went to fly it. Unfortunately on its first voyage he crashed it pretty hard into the ground and it wasn't to fly again. I was pretty sad (10 years old or so), but now I know that such wasn't uncommon.
Wonderful suggestion! You’ve got it just right. Excellent line of thought.

The "wisdom of crowds" is mostly bullshit. It works fine for trivial things like estimating the number of beans in a jar. So what. It completely fails for anything requiring deep expertise.
I continue to not understand the position that the default provider of health insurance has to be either your employer or the government. What makes it fundamentally different from housing, food, or transportation, where you just pay money and there's assistance for people who can't afford it?
Some people do not prefer that, and it is NOT ok to force it down their throats by force
NYC has 30,000 streets and only a handful of days of snow in the year. By having garbage trucks that can deal with a few inches of snow, you avoid the need of buying dozens of dedicated vehicles that will rot 360 days a year.

I read somewhere (if someone remember it, please tell) a short history about life in neutron stars. It would be incredible fast due to the abundance of energy, with the evolution from 'stone age' to computer age happening in milliseconds.

Due to being in a deep gravitational well, such life and life inside a star are forever isolated from us. Unless they discover a way to use solar flares, in fact, perhaps solar flares are their way to escape the surface of the sun.
We're seeing the most successful Big Pharma marketing campaign since OxyContin.

The Promotion and Marketing of OxyContin: Commercial Triumph, Public Health Tragedy

> From 1996 to 2001, Purdue conducted more than 40 national pain-management and speaker-training conferences at resorts in Florida, Arizona, and California. More than 5000 physicians, pharmacists, and nurses attended these all-expenses-paid symposia, where they were recruited and trained for Purdue's national speaker bureau.

> One of the cornerstones of Purdue's marketing plan was the use of sophisticated marketing data to influence physicians’ prescribing.

> Purdue “aggressively” promoted the use of opioids for use in the “non-malignant pain market.” A much larger market than that for cancer-related pain, the non–cancer-related pain market constituted 86% of the total opioid market in 1999. Purdue's promotion of OxyContin for the treatment of non–cancer-related pain contributed to a nearly tenfold increase in OxyContin prescriptions
