This is false; anyone with a $30 pulse oximeter can disprove it. I've checked my oxygen levels; there are a bunch of videos of healthcare workers demonstrating it has no impact.

St. Vrain was helium cooled and graphite moderated and it only ran at 1430F, which still caused some hair-raising operational problems: https://www.nrc.gov/docs/ML0403/ML040340070.pdf

High temps are very good for efficiency, but are difficult for safety. Only China is building VHTRs right now. If anyone ever builds a supercritical water reactor then it would give you decent efficiency without the problems of exotic coolants.
The votes look legit to me.
This article puts a lot of emphasis on his lack of degree.

Have we forgotten what a "degree" actually means? When you receive a diploma, it just means some institution is willing to attest that you have achieved some sort of qualification.

You can learn something without approval from an institution. Diplomas are typically expensive, so it's not always worth it to get one. Why is this such a foreign concept?
It's not. Welcome to okay-land.

This is actually a very important point in lieu of the linked article. In the absence of evidence, we have sometimes have to resort to common sense. The old phrase "say it don't spray it" comes to mind. We've all been there.

Also, as for sneezing or coughing, I suggest actually trying it with a mask on if you doubt the efficacy of whatever mask you're wearing. I have and can tell you my shitty cloth mask blocks a significant percentage of particles from entering the air around me. I don't need science to inform me about that, I can literally just feel it with my own face.
Great tip. ComputerCraftEdu looks really cool. I'll try it.

Mmm, that's a tasty word and definition. Thank you for sharing the meaning of "meditation" in the Old Testament sense of the word.

A similar word comes to mind, to contemplate.

> contemplation (n.) c. 1200, "religious musing," from Old French contemplation and directly from Latin contemplationem "act of looking at," contemplari "to gaze attentively, observe; consider, contemplate," originally "to mark out a space for observation,"

> from assimilated form of com-, here probably an intensive prefix, + templum "area for the taking of auguries" (see temple (n.1)).

Tangentially related, in Japanese there are (at least) two senses of "to think".

- 思う - to think, feel, remember, believe

- 考える - to think, cerebrate, cogitate, presume, take for granted, assume, conceive, consider

As someone who grew up there, it's hard to describe the difference in English. The first one is associated with feelings and images, and the second one is more about logical thinking.

For me, I have some thoughts or ideas (some of them from books I read) that I've been pondering for many years. That feels like 思う - it's a long-term, more abstract kind of thinking, often in the back of my mind. I find myself coming back to them, almost by chance, and discovering new perspectives and depths.
qb64 is great for an intro to programming. I am teaching a young child to program. One of the things I noticed, is that they had difficulty with “if” and “else” blocks. The concept of a block of code that gets executed together versus another block of code just wasn’t intuitive. I changed to basic “if ... goto” and they immediately grasped the code. It was just a labeled linear set of instructions that you just followed starting from the top and going down unless you encountered a “goto”.

Once they get more facile with programming BASIC in this style, I will introduce them to more structured programming.

BASIC is a great intro language for non-programmers cause it is so linear and there are few extraneous noise (for example the parentheses in Python 3)

Ask HN: Should I use “raw” LLVM IR or some wrapper over it?
Hi!

I feel like HN seems to be good place to ask this question because compilers seems to be quite popular topic here, so I'm going to ask

I want to write yet another programming lang which uses LLVM to generate WebAssembly

My perception of it is that I have to write parser of my lang and then some "translation layer" which will translate abstraction over my language to LLVM IR

But I'm not sure whether I should write "raw IR" or use some library like https://github.com/microsoft/LLVMSharp

I feel like "raw IR" is better / more reliable way, but I've no experience with low lvl stuff (asm and so on)

Also I'm not sure about how good LLVMSharp actually is

PS: I've heard about other LLVM IR wrappers in other languages, I'd rather stick to C# because I have some kind of deadline on it

Thanks in advance
> Despite Collison’s example, most CEOs probably won’t take that risk on their own; they will be too afraid of being undercut by less scrupulous competitors who retain their access to China’s markets and manufacturing prowess. So on this Fourth of July, it falls to the American public...

This is the weakness of American individualism. Some form of organization is necessary to achieve anything meaningful here. This is a job for regulation/trade policy. Attempting to shame individual companies or "the public" is at best pointless, and at worst a distraction from a real solution.

There's a pretty funny example here from the tech world: web search, google, and microsoft. What has been achieved by google abandoning the Chinese search market? It sure as hell isn't respect for that decision. Far more vitriol (even at the level of US congress) has been directed at google over this than microsoft, who operate bing in China!

Don't get me wrong, google deserved the criticism over dragonfly. But where is the outrage over microsoft operating bing under China's censorship policies? This is why organization/regulation is required: people are really bad at maintaining a coherent position even in the absence of market pressures, which are massive in the case of trade with China.
> An issue with these things is that institutions and government make major decisions based on the output from these fields.

Indeed, the mere proliferation of x-studies (where x is arbitrary) in universities is a ringing indictment. The classic/liberal humanities (e.g. history) should be taught but it shouldn't be the case that one must go to a university, and get into debt, to learn them, and within a university where they are taught, they shouldn't be degree courses unto themselves.

Music is taught excellently in conservatoires and art taught in ateliers imho produces better artists than are produced by universities. Both are often an order of magnitude cheaper than a 4-year university education and encourage/reward the repetition necessary to achieve excellence in those who aren't naturally gifted.

Any field that has to append "science" to its name usually isn't scientific e.g. political science, social science.[0]

I sense your a pretty emotional person and are quite upset at your current economic decision.

So lets start with your point.

Trickle down economic does work in its truest form. It starts with a person who creates a business. This business makes money through the work it does. The owner gets paid more and decides they can create another business. A business larger with more employees. Overtime, the owner creates many more businesses and employs more. Providing its employees with cash, to spend at restaurants, on boats, on houses, on daycare and many other businesses that the employees like to spend money on. Therefore jump starting more business owners to spend more.

This is trickle down economics and its working. I think the thing your upset about is the idea that these business owners, the wealthy are not creating and doing more. I disagree and the US economy would disagree. You simply might just be detached from the economy. So your quite upset about it.
Ask HN: Go-To Programming Communities Today?
Where are you frequenting lately now that the IRC protocol is not so fashionable anymore.
Stack Overflow seems to be dying slowly but surely as a community and I am not sure about the message boards. Are there still any active and dedicated programming Internet forums out there?

There is a notion that GitHub might serve you as a "Stack Overflow" and as far as I am concerned it does to some extend. You'll find some workarounds and fixes to a particular programming issue over at GitHub, but you probably won't find any explanations to some programming idiom or concept.

Discord has dedicated programmer communities as far as I am concerned and also better overall UI design.
Some programmer folks are apparently content with Twitter. Twitter however, doesn't strike me as a good programming community as it lacks features facilitating a reasonable discussion about source code.

Perhaps, there are people who abstain from communities altogether (except HN of course) and go on having a discussion about programming with "real people" (e.g. peers, friends, ...) and if they have an issue with their code they will just google for a solution and be done with it or they will refer to their peers, co-workers and what have yous. :)

But I suspect it ain't easy living the programming life without Google and perhaps even online communities as programming languages get more and more complex or rather feature rich (C++, Java, Python to name a few).
Hard to imagine someone just consulting an official documentation about a particular framework or language and be content with it for eternity. Google is you friend I would say. :P

Websphere MQ has had DB2 as a dependency for ages. Not by accident.

OTOH as a sysadmin I hate when developers use queueing systems as databases. It's like keeping full courier vans circling around the city instead of having a warehouse. Messaging systems are pipes, not water towers. It makes monitoring difficult, makes browsing and modifying data difficult, and administration difficult. They may be sides of the same coin, but that doesn't mean you have to use only a side of it.
Blood oxygen saturation is not informative in this context, and it's disconcerting to see medical professionals treat it like it is. You can hyperventilate until you pass out without your blood oxygen saturation changing.
>they ask obscure questions aimed at knowlege gained in a computer science degree (or by good test preparation).

I don't think this is the focus of their questions. Their questions are more like IQ tests with a CS spin. The knowledge itself is trivial, it's how you use that knowledge to solve problems.
This is also incidentally the exact sort of thing the Defense Production Act is actually for. It could be invoked, used to give guaranteed quantity and price contracts to suppliers and avert the entire issue of supply runs.

Which likely wouldn't happen because it's not like someone who gets a profitable contract from the Federal government, retools their factory, isn't going to then try and squeeze as much production out of that as they can anyway.

It's easier to fly under the radar when you act to blend in with your environment. If you went to an economics conference in cargo shorts, you are going to stand out. I am pretty sure that a lot of biases are towards how people dress and act rather than skin color, in this given situation. I've snuck into conferences before, generally there are so many people that as long as you are dressed the part and act appropriately you will not even be noticed. Many of the most prestigious economists in the world are people of color, so I have to say what he's saying is largely nonsense.

Anyhow, MMT is a very popular thing right now, so it's obvious he would get attention regardless of his age, gender or race.
I appreciate the correction, but frankly this isn't what I hoped people would take away from my comment. My point was that race/gender/appearance plays a large role in gaining access to normally stratified resources
Be careful in your assumptions here. Online degrees still carry a huge negative stigma with them (which is interesting given that all students in the current cohorts at normal universities will have had several semesters of remote learning). Signalling of the college brand is also largely underappreciated by online students. You're getting a degree for a fraction of the cost of an in-person one, but it may or may not also carry a fraction of the job market value.

Note: I do not know which school you are referring to. It might be Berkeley's $70k+ degree or one of the many lower-tier schools, so YMMV.
In the new deal era IT was 0% of GDP. Now 25% of the SP500 is FAANG. Not even mentioning the change in health care stocks.

Financialization occurs when you can be explicit about costs and benefits. Finance does it with dollars, IT does it with bytes.

There is certainly a case to be made that it's gone too far. But honestly you should be pleased if people can move billions of dollars to a positive end with a mouse click.

Stock values follow profit. If the finance industry can encompass 100% GDP and break down everything into profit and costs that can be allocated to the individuals with the correct risk profile, we're doing extremely well.
The claim here is that 1) CDC knew masks were effective but 2) decided to ignore that to preserve stocks.

For you to support claim 1 all you need to do is post links to the meta-analyses or randomised control trials that show the effectiveness of masks to prevent the spread of respiratory disease. There are lots of RCTs around mask wearing to prevent the spread of respiratory disease.

> And they too admitted to spreading FUD about masks

No they didn't. They haven't even changed their advice. Now they say "it may prevent the spread", they definitely don't say "it does prevent the spread", and they're still trying to preserve stocks of medical supplies.

By all practical measurements of safety and cleanliness, nuclear is extraordinarily clean, safe energy yet it keeps being attacked ferociously and without good reasoning.

This is something that I’m warily watching as we move towards a predominantly BEV fleet. I don’t like the idea of subscriptions in software, and I really don’t like it when it comes to vehicles. It will be interesting to see how automakers deal with users who take matters into their own hands and start tinkering with code in order to access features that would otherwise be locked away if you don’t have a subscription. There’s already lots of experience in the ICE world of tuning the ECU, and I wouldn’t be surprised to see them have a “secret menu” if subscriptions become rampant across vehicles.

(From Nathan's Twitter after this: https://mobile.twitter.com/NathanTankus/status/1278777095670...)

> I do have a credential- the intersection of my whiteness, maleness and cisness.

Wow, wasn't it just yesterday a post blew up about political correctness gone mad?

I suppose Nathan wanted to get in first and "apologise" for his whiteness, before his rise to fame (which has coincided with the rise of a... particular socio-political movement) punishes him for it.

Isn't it enough to just say "if you're good at something, you don't need a degree"?. But no. He took to Twitter to perpetuate the woke, self-denigrating culture of white Twitter to ensure that his success wasn't hampered by the mob. PC culture has reduced people to snivelling, grovelling shadows of themselves that can't think for themselves.

Forget blind-hiring practices! Should we be putting disclaimers on our resumes that points out if we're a white cis-male so that a company can appropriately punish us for the sin of being born a particular sex and race?
There's just about infinite surface area with the API — we're trying to build a dead-simple API that developers can plug into any product in order to add intelligence features that would be otherwise impossible.

This requires a lot of traditional software work — API design, writing and maintaining a growing amount of business logic, providing great tools and interfaces to help our users work with the API, excellent documentation and tutorials, scaling and operating backend systems, etc — and machine learning systems work — building serving infrastructure for a great variety of giant neural networks while making the most efficient use of our hardware, allowing our users to interact with these neural networks in increasingly sophisticated ways, etc.

While we're just getting started and have a small team, we are already supporting customers across a wide variety of industries (see https://beta.openai.com/ for a sample) and serving millions of requests per day. We are busy trying to invite folks off a very long waitlist while building out the API to support everyone.

Would love more help :).

Post a link to any RCT that shows efficacy of masks to prevent the spread of respiratory illness or retract your "lie" comment.
The first step is to have a large, international NGO overseeing the sport. This is one reason why e.g. American Football isn't an Olympic sport.

That NGO must have a proven history of enforcing the Olympic Movement Anti-Doping rules, including out-of-competition testing of athletes. Imagine if top fortnite players had to submit to random year-round drug testing to be allowed to compete.
> The PoW is suffice if the hash begins with a certain number of 0s

This is a common explanation of PoW, but is actually incorrect. If you think about it, this would mean that the PoW difficulty could only increase (or decrease) by a factor of two. In reality, the block hash is simply interpreted as a (very large) number, and this number must be less than some other very large number (the "target"). So you do end up with a lot of leading zeros -- but these are just a side effect, not the thing being measured.

It's not bad as a first idea, but there are a couple difficulties with it.

1) We know sedentary hunter-gatherers existed throughout the upper paleolithic. This is a bit of an under-researched area for various reasons, but we know they definitely weren't all mobile.

2) Humans had been continuously inhabiting areas in east Africa since even before they could be called anatomically modern. Yet, agriculture there emerged at roughly the same time as elsewhere.

3) The earliest agriculturists were semi-sedentary anyway, not predominantly sedentary and fixed in place. How mobile they were depends on where and when we're specifically talking about, as it varied over time.

4) Climatic variability in New Guinea (another early center of agriculture) actually increased during/after the younger dryas.

This one's a bit unfair, as it's outside the scope of what I originally said. Nonetheless, it'd be nice if we could also use our explanation to say things about independent domestications long after the start of the holocene, like the eastern agricultural complex.
> How much benefit have I drawn from looking like a programmer

On the other hand, our profession does have the benefit of being able to be done with zero knowledge of appearance. In fact, I credit that fact to enabling smart teenagers to make key contributions to open source they otherwise would be excluded from due to assumptions coming from age.
Nowhere in your comment I see you mention that elite institutions are mainly research institutions that do teaching kind of as a side job. In fact, several of the best researchers working at universities are horrible teachers.

However, if you want to be at the cutting edge of your field then that is where is at.
There is no equivalence between a meter reader and a police officer's situation. Some subset of police interactions may be similar but many will be very different. A police officer's interaction is much more likely to be heated, urgent, close quarters, and unavoidable. A meter reader can just leave if necessary, which is what they do.

For example, police officers frequently have to enter a home during a domestic dispute with a dog that is riled up due to its owners having a physical altercation.
That could be. But afaik it hasn't been attempted yet.
