I know very little about nutrition but have wondered whether taking supplements actually help, or if it's the process that _creates_ those vitamins that's actually important/healthy.

Like in your example, being exposed to sunlight starts a process in our body that's healthy for our bodies, and vitamin D is just a by-product... and taking it as supplements wouldn't really do anything as we're missing the process.

As I said I have no idea what I'm talking about.
True :) Economists have questioned the efficacy of QE though.

Brain-scanning backpack brings neuroscience into the real world
> mandatory installation of powerful ventilation systems

In my country that's already been a thing for the last few years. The HRV system is around €1000, so it isn't a major cost for the benefits you get. From this year all newly installed units need to be 90% efficient.

Also "powerful" is probably not needed, the system I have at the lowest speed changes the air in my entire apartment every 3 hours, and is basically the same noise level as a barely audible computer fan.
you might want to consider temperature as a possible culprit. a lower temperature is a signal to the body to curl up and sleep, and a consistently cool (relative) temperature keeps you in that state. when we wake up, our bodies ramp up our metabolism/temperature to rouse us out of slumber. i know i'm ready for sleep when i impulsively reach for the sheets. with two people, a dog, and only a cracked window, the temperature might be rising above your sleep signal during the night (i wake up often in the middle of the night and can literally feel the heat rising as i gain consciousness).

What you put in your product is indissociable from how you design it to accomodate users. As per my other reply, the problem is wanting to accomodate all users for all the data, actions, and processes.

This clutters product. As per my other reply, one solution is to break functionality down. Keep the core tight, the rest becomes plugins that users install to solve their specific problems or a family of problems (categories).

No product can satisfy everyone and all processes and actions and be useful at the same time.
I don't care, as long as I end up with a profit on the bottom line. I'm not in competition with anyone, nor doing this as a career.
I keep seeing data points like this, but does supplementing vitamin D work? Does it make sense to read things like this and conclude that taking a vitamin D supplement pill daily is a good idea?
> fair number of smart folks who are in the know view VLIW as something that was tried and failed, so they're dismissive of new designs which use VLIW.

It’s not different, because businesses that are “VERY inefficient” often end up dying. There’s no structural permanence baked into the corporate system that guarantees that a corporation will exist forever. On the other hand, governments and state actors are largely static. The institutions and systems that govern them seldom change. And the larger the polity, the harder it is to build up the political will for democratic institutions to evolve/change. It is very difficult (IMO impossible) for an inefficient government to “go out of business”, so to speak.

> There are disadvantages with size and also sometimes advantages such as economy of scale

This is absolutely correct, but the market system ensures that whichever corporation becomes large enough to deliver on those economies of scale is selected as a function of their ability to deliver (for the most part). Ask yourself what would happen if we democratically granted Sears a legally authorized monopoly to essentially exist in perpetuity like states and state programs exist today. Would they have been able to efficiently continue delivering value as the world changed? Would we have allowed them to die and be replaced? The fact that they were defeated to the point of bankruptcy by Amazon et al is a feature of the system that is notably lacking in state institutions.

In fact, the state institutions that perform the best are the ones that are the smallest/most decentralized: https://www.reuters.com/article/us-health-coronavirus-podcas...

Ask HN: Technology Reasons for Snowflake Hype?
I’m trying to understand the SNOW IPO from a product perspective - what is driving the interest that is not related to stock price growth (a unicorn)?

I have tested the platform a bit in a trial, and it is interesting, but comparing BigQuery and RedShift I’m missing what makes it stand out justifying its market valuation.

Has anyone used at least two of these platforms and can speak to specific features or capabilities?
Mill has nothing to show for it.

Mill has no answer for the unpredictable cache misses. Their belt idea is cute and interesting but inconsequential and irrelevant.

The main challenge of the modern microprocessors is not in how many ALUs you run in parallel nor how you model and implement your register file, but how to keep the ALUs fed with data from the memory hierarchy. VLIW doesn't help you with that at all, which is why it is largely irrelevant and a tiny niche.

For applications like GPU, you address the feeding problem with multiple threads through SMT/SIMT and multiple cores, and SIMD.

For applications where a single thread performance is important, you use OOO and/or speculative execution to maximize the feeding of the data.

If you only care about running a particular loop and you only need to meet a fixed cycle budget like DSP application, VLIW may make sense when you want to save some engineering time and you have relatively low volume. Once volume is high enough, you will likely choose an in-order superscalar instead, for better performance or even simpler implementation, ease of programming, better backward compatibility and higher instruction density. VLIW has become more of a niche even in DSP. E.g. see
https://www.eetimes.com/a-case-for-superscalar-dsps/ which is now almost 20 years old article.

The basic idea behind VLIW of moving as much work as you can to the compiler is not wrong, but VLIW turned out to be a bad way to divide work between the pipeline and the compiler.
I left Reddit because the extreme levels of opinion mixed with self-righteous cynicism inevitable in every single thread was unbearable. I enjoy reading conversation threads, which I think Hacker News has basically mastered. Reddit, not so much.

These people think they know everything, dramatize the crap out of their hostile opinions, and yet as time goes on, they're quite often proven wrong. But that's what they seem to enjoy, so let 'em at it.

I see Reddit as a rite of passage. Go there in your youth and pretend you know everything. Once you grow up and learn you don't know everything, move onto less obnoxious forums where you can discuss things like an adult. Not everything has to end in a meme of the day or an attack based on someone's assumptions of your personality/ knowledge/ skill/ appearance/ etc.

No, power generation is about a quarter: https://www.epa.gov/ghgemissions/sources-greenhouse-gas-emis...

Transportation could push that total to 50% if all ICE cars were converted or destroyed and only electric vehicles were used (ignoring ships and trains). "Industry" includes CO2 waste byproducts which are much harder to reduce as many processes may struggle to eliminate that byproduct. Instead capture and sequestration would be needed. This is another 25%

The rest are small, but since we need virtually all CO2 emissions to be zero, we are left with nearly another 25% that isn't tied to electric production and is difficult to replace.

So, 50% of all CO2 isn't power generation related.

Recruiters...ugh.

About 15 years ago I managed a software team and decided I wanted to consider new opportunities. I wasn't sure I was leaving, but I wanted to see what was out there. A recruiter saw my resume, called my workplace to speak to the hiring manager, and offered his services to help the company fill their soon-to-be-vacant development manager position.

The recruiter was happy to reveal that I was considering leaving until he realized I was the hiring manager he was talking to. He quickly hung up.

There is a convention that an organism that can't be found anywhere by scientists (with a reasonable effort) in the last 50 years is classified as extinct.

In the meanwhile is 'probably extinct' or even 'functionally extinct' (If only specimens of a sex, or unfertile remain) but is not the same category.

This is a cultivar, not a species, but the idea is similar. If we talk of a fruit that was forgotten after 1920, yes, it was extinct.

In any case the image of the dying tree with a last branch is suspiciously romantic, and wax fruits are not a real proof of anything. Without DNA analysis we can't guarantee that this is the real thing, could be also a seedling, a different clone mutated, or a forgotten cultivar that lost its tag, but is still sold in other place under a different name.

When a fruit is forgotten there is normally a good reason. Maybe, being so similar to Cox's Orange, will show poor resistance to fungus diseases. There is no reason to reproduce a worse version of Cox (and in the article I would expect a genetic comparison between both apples at least).
Linux has worse GPU options (and other hardware too).

I agree.

I don't know why the press article choose the first image of Figure 4, the second image is much more convincing. (You can see clearly the toes, except the middle one.)

Also, in the bottom center of Figure 1 you it is possible to see that they found 4 footprints in a row, and if you imagine that there are one or two missing footprints they are at the correct distance, like the path of someone waking. (Why there are only right footprints and no left footprints?)

Well, you can't really separate things that way because they're inter-related, but honestly, I don't really have a ton of motivation to bother replying to you anymore. Embedded languages / domain specific languages vs not is pretty well-worn at this point, I don't have anything new to say here.
I don’t see the flow of money to tech and (select) real estate as irrational. Tech has a proven business model of earning the most net income, extremely high margins, extremely low marginal costs, high barriers to entry, and extremely high ability to price discriminate and get paid.

Real estate offers natural monopolies, enforced by the existing political order. Biggest risk to real estate is climate change and economic conditions, but it typically doesn’t become worthless, and it continues to exist without any work on your behalf.

It just occurred to me that our political news discourse has gotten so bad, it was easy to assume "the arena" could be the name of a news / opinion show, but my mistake.

>it's almost as if we need to break off high-value, low-engagement news organizations into fully independent non-profits that are funded by a pool of income from the infotainment industry for the right to continue delivering low-value, high-engagement infotainment, rather than intermixing the two.

We absolutely do, and I think there is a demand for it, just not sure how it would ever get funded because the investors would always want the higher return the anger-tainment style would bring. I try to focus on individual / independent journalism when available. I'm just starting to (audio)read Woodward's new book, and it seems pretty fair so far. I thought his last book seemed fair also. The difference of the new book is quite stark compared to the media's take on it recently.

I remember early in his presidency, watching a Trump speech. A short while later I saw news coverage on that same speech and it was like they weren't even talking about the same event.

ejected myself from a twitter addiction just a few months ago and this resonated.

i think people read the “zombie” comparison as metaphor; IME, it’s pretty literally accurate.

the realization that snapped me out of it cold turkey was that my twitter “self” —- cultivated outside of my body, for an environment of pure text —- had accumulated far more status, meaning, friendship, etc than my physical self possibly could; and why wouldn’t it? the internet has no friction in comparison.

so that weird external GPT-3-esque “self” quite literally reached primacy within me, with a huge margin over the original one unlucky enough to be constrained by physical reality & trained via physical human interaction: and as a result i was genuinely zombie-like for a while.

perpetually a disoriented visitor to physical reality, to the people actually around me — only at home in text. and it was probably clear to anyone who knew me in person well.

maybe annoyingly mystical for HN’s taste, but when this clicked for me, it felt like discovering i’d been possessed by a demon.
Maybe i misinterpreted what GP said. curious if you have an example where you took a candidates feedback and improved your process.

If you company does leetcode puzzles ( I worked at such a company) for hiring and a candidate tells you that they felt like that processes lacked basic human decency. What would you do?
Nix basically already does this, apart from the decentralised distributed cache (there is a centralised one and you can easily set up your own, too). All references, including to dynamically linked libraries are via unique, content addressable hash -- where "content" currently still happens to be content of the build recipe and all dependencies and sources, recursively, not the built artefact. There is work on referencing artefacts by the binary output hash though, because that obviously has better security properties when you want to have a non-centralized cache; the main problem is that a lot of software still has no reproducible build.

I think he means postmodern in the common sense of the postmodern movement.

Modernism was a architectural and philosophical trend that peaked in the 50s. It really got started a few decades earlier than that. Think of uniform apartment blocks: modernist architecture in action. It was a sense that we were finding the universal laws of everything and we could make things equal and fair via uniform architecture for example.

Postmodernism was a critique of that and a deconstruction. Modernist ideas didn’t work all the time and for everyone.

If you’re referring to “now” the word you can use is contemporary. Meaning “along side”. This works for more things eg: “Albert Einstein corresponded extensively with his contemporaries.” Or “I dislike contemporary architecture”.
Free speech is when anyone can say anything they want, but if you've followed the trends in Silicon Valley for the last couple of years, there is no more free speech. One cannot for example say they are pro-Republicans, or against housing, or basically pro/against anything that is not in line with the mob, without getting in trouble. Professors are being fired, executives are being let go, all because what they say goes against the group-think.

THAT is the opposite of free speech.

Free speech should not be only available to those you agree with. When an ideology is being forced on you by a loud group that says "you are either with us, or you are against us," that is not free speech.

There's one minor issue to look out for, which is the social aspect. For better or worse, "computer science" has become the hot field that hyper competitive parents want their kids to study. It's the new "pre med." Some kids thrive in it, others are turned off by it.

That's my observation as a parent, not a commentary on computer science itself.

It's just something to watch out for. Some kids will need help maintaining interest and valuing their own abilities in that atmosphere.

Yes BUT...

I haven't been in too many situations where I've been actively looking for employment/engagements, but some of the times I've been in those situations, everything was bad. It's difficult to go back and 'share' those with people - publicly - as it brings back a lot of bad memories of those time periods. Low funds or debt, downsizing, loss of friends/community, home/life issues, family issues, whatever. Scenarios where someone is looking for a job are often stressful, and that often can spread out for months, and affect the family and friends around you.

I'm happy to share extreme details of my situations with people in person, offer up support and give advice and insight about someone's situation by drawing on my own experiences, but... typically only in person. Publicly... generally not.

There's not just 'shame' issues for yourself; when you have a family, posting information about your failures can have an impact on your family as well, which they may not want.
