If built, it would compete directly with Etihad Rail, which is building a regular rail network throughout the entire UAE and already has its first phase operational:

https://en.wikipedia.org/wiki/Etihad_Rail

This focuses primarily on cargo, but is built with passenger trains at up to 200 km/h in mind. And most Hyperloop business plans also seem to rely heavily on freight.
There are a lot of good arguments and suggestive evidence that the exact opposite is true: that we were competitive in our environment not because we were selfish, but because we were social, altruistic, caring, supportive.
This is taken to other extreme many times.

Example: Google Chrome codebase was allocating lot of std::string and also someone used a Set to check membership of single item. [1]

I mean, if you say like this, many people don't even care about algorithm complexity.

Doesn't help that people want to write Python in the monster that is C++.

That video doesn't talk about the Hyperloop at all. You're getting the Boring Company's Loop mixed up with the Hyperloop, which despite the similar-sounding names have close to no relation.

I think the preferred term is "allowlist" not "whitelist". I like Allowlist personally because it's immediately obvious what it means esp for less technical folk. It takes time for new terms to become commonplace.
Payne-Gaposchkin was given an extremely raw deal by Otto Struve at Chicago. I would say she got screwed over more than Henrietta Swan-Leavitt or Rosalind Franklin (but not Jocelyn Bell-Burnell)
Is it really 2 minutes longer? Subways move millions of people a day. Your loop tunnel will have 1/100th of that capacity. There will be no traffic jams, waiting at the elevators, to merge / separate traffic? Are you addressing some fantasy scenario where you are the only person using a city-wide system?
Exactly this. I thought this must be the reason suggested by the headline and was really sad to see barely any reference to it even in the comments...

Thank you, a drawback of “read this public domain book” is that (while I should read it anyway) the HN thread will be long dead when I finish.
Admit It, You Do Laundry During Work Video Calls
But you aren't just doing it a chemistry lab. You're doing it in an enormous tube and the tube has openings to allow pods in and out, so it's a lot more complicated.
We all start out this way, don't we? I think what drove it out of me was having to maintain. Okay, you wrote this thing, now you need to change the way a few features work and add some others. Especially effective is if you take turns being on call, getting paged in the middle of the night when your multilayer architecture has a hiccup and now you have to troubleshoot it.

I wish there was a quick remedy for such people. But usually they are new, based on what I said. So they should be Junior Developer, not Architect. Sure, you can suggest things, but the answer is nope.

A lot of people, though, may never get much experience supporting their own architectures, because they swoop in, then swoop out, never staying at a job long enough. Or support gets assigned to another group. One thing I like about Agile is that the team that creates the code is the one that supports it.

At first, I thought raising price would do the Job, Wafer is still relatively cheap, It is the Design / Up front cost that is expensive. Higher Revenue > Higher Profits and in turns can paid Engineers a lot better.

But then there is Samsung, which has its foundry business partly funded by NAND and DRAM. i.e TSMC cant exactly dedicate the price as much as everyone think they could.
Also, what happens if the pods leak? Seems like the air in the pods will diffuse through the tube and the people will suffocate.
MDN is more important than Firefox actually.

One thing neither this article nor the linked study measure is if there is a difference in this behavior between boys and girls. I looked through the actual article to see if there was a statement that said if there was a statistical difference between the two or not, but although they do specify the numbers for the genders of the participants in the study, none of the analysis does any comparison between the genders.

It would be fascinating to see if there are gender differences in this behavior in childhood and adulthood and compare childhood and adulthood.
300-500 IU/kg/day vitamin D3. 5-10 mg vitamin K2 MK-4. 100 mcg vitamin K2 MK-7. 1.2 grams magnesium. 500-600 mg calcium from all sources. ZMA (if male). Eventually melatonin to keep at level of youth.
The author explains the following, regarding Vitamin D studies:

> Most studies follow this pattern: Two sets of people are evaluated. One set has a certain disease (diabetes, for example). The other set does not have the disease. Vitamin D levels are measured in both groups. Vitamin D deficiency is found to be much more common in the group of diseased individuals.

If this is true, I wonder if most studies aren’t falling short for failing to control for Vitamin D deficiency. Couldn’t the studies be structured differently?

Let’s say we want to know the effects of Vitamin D on Covid. What if, instead of measuring Vitamin D deficiency in a group with the malady and a group without (analogous to what the author suggests most studies do):

We had two groups made up of Vitamin D deficient people. We gave the first group a Vitamin D supplement and the other a placebo. We then observed both groups out in the wild (ideally a place with a high R), measuring for infections. If the supplement folks were infected at significantly lower rates than placebo folks, wouldn’t this be better at demonstrating causation?
i still remember the time (early in my career) i was summoned to jury duty and tried to register an "undue hardship" with the judge because i had a project deadline coming up.

i genuinely thought it was that important, but looking back it was really not a big deal at all (and the judge knew it) :)
It’s insane how often people stick Memchaced/Redis in front of MySQL/Postgres, completely unnecessarily. So many otherwise decent developers assume that MySQL/Postgres is too slow/doesn’t scale, without even trying. Or similarly, how frequently people shard databases unnecessarily. A single MySQL/Postgres server, on a beefy machine, can handle an absolutely massive amount of work, with great performance, assuming you’ve indexed well and don’t have to run super crazy queries.

I’ve worked on some pretty high traffic systems, with pretty large data volumes, and very, very rarely have I actually needed to cache simple DB reads. And it’s hard to properly cache complex ones anyways, because cache invalidation is so hard for complex queries. Likewise, it’s very rare that I’ve needed sharding. SOMETIMES you need these things, but mostly people are adding a lot of extra complexity and cost for no good reason.

Yes, but... as an author, I’m stuck using Word for working with editors and publishers. (I prefer to use Scrivener.) Using any other application is a bad idea due to incompatibilities. This isn’t theoretical. Change tracking is critical and the “mostly correct” support in other applications is not an acceptable compromise.
I was really excited for this, I want to buy it and am willing to compromise for 1st generation hardware. But no NFC means it impacts my life substantially, from payments to public transport. I hope they reconsider the lack of NFC for the next generation.
This is a great idea! I'll plan on adding this soon, if the tool gets more feedback and usage :)

Well I wrote not React Native for mobile dev, but I'm the wrong person to ask in any case. I learn best by starting a project with something I'm totally unfamiliar with and just... going. In fact I find learning other ways almost intolerably dull and am unable to stay focused, when it comes to computer stuff (other topics, I don't have that problem). So from my perspective, the answer to "how best do I learn this computer thing?" is going to be "just start a project—ideally one that pays" about 95% of the time. Or pick a simple-enough-looking but not-dead project in the tech on GitHub and start contributing.

I gather other people like reading docs (OK, that's alright) or tech books (ugh) or watching videos (double ugh) or listening to podcasts (triple ugh) to learn computer things. I almost never do most of that (aside from consulting docs), especially not when first approaching something. I am, therefore, just about the worst person to ask about resources for learning any computer thing.

My only suggestions other than that would be to use Create React App, because the alternative is the sheer cosmic horror or a complex JavaScript build, and that goes at least double if you're doing React Native rather than browser-targeted React, and to start a React project with TypeScript because without it JavaScript is kinda miserable, and there's little reason not to.
Or, similarly and more recently, Graeber's idea of "bullshit jobs". As mentioned in your link, we need to slow down economic growth if we're going to have any shot at all of slowing down climate change, and that will conveniently require us all to work a lot less :)

Julota – Connecting Your Community
Since this is getting to be a bit popular, I'm going to push the "technology really doesn't matter" point a bit more here: in 1955 the French built this [0] (just look at the picture!) and sent it down a traditional (wooden sleepers, rocks for ballast) rail line between Bordeaux and Irun [1]. It got up to 333 km/h, which is faster than any TGV currently operates in the year 2020 on their fancy concrete HSR tracks.

[0] https://en.wikipedia.org/wiki/File:SNCF_BB_9004_photo_1.JPG

[1] Side note: that bit from Bordeaux to Irun is quite possibly my favorite train line in the world. Absolutely beautiful views towards the Irun end.
From a safety perspective 0.01 atm = 0 atm. That tube is either very dangerous, or very overbuilt and expensive.

Your assumption is that the bias is only racism, when sometimes it’s racism and sometimes fear of being robbed/assaulted. Stars definitely curbs the latter.
From what i notice this is looser and easier to create notes. The nodes can be connected in any aleatory way, you can even make circuits. Mind maps are organized in a different way which might yield better results for different tasks

Vaccine efficacy is not yet proven. Even if highly effective, vaccines will take years to circulate the world. Something like this, much easier to produce, supposedly, can fill that vaccine gap.
That doesn't solve the main issue: that recycling programs are partially subsidized by profitable waste. eg. cardboard and metals might make a profit when factoring in cost of pick up and processing, but plastic might not. At the same time, you want to promote recycling across all types of materials, so you don't want to penalize people for recycling plastic[1]. If you have private companies picking off the profitable waste, the taxpayers will have to make up the shortfall. You see the same funding model in other areas as well. eg. the postal service https://en.wikipedia.org/wiki/United_States_Postal_Service#U...

[1] Although some argue that if something isn't worth recycling at market rates, then we shouldn't recycle it at all, because it likely means that it's a net-negative for the environment.

> It's very irritating talking about whatever hyperloop is, because that the bar for what the hyperloop is keeps changing (Is it tunnels? Is it in a vacuum? If there's no vacuum isn't it just a tunnel? Is it your own car or a pod? There's solar panels somehow?).

The Hyperloop concept is exclusively a pod in a vacuum tube. The electric cars in a tunnel concept is called the Loop (no Hyper), and it's a different idea entirely developed by Musk's Boring Company (which in turn has no involvement with Hyperloop development). The names are very similar, which has caused a lot of confusion, even in mainstream media reports.

I mostly agree with the rest of your comment.
Building a Passive Sales Machine: Email Drip Campaign Design
Ah yes, I posted the wrong video. My bad.
I find it interesting, at a glance, most of the comments here seem to take for granted that everyone uses a dishwasher.

I haven't used a dishwasher in about 20 yrs (not bragging, just stating a fact). In those 20 years 13 of them were in Japan, and 7 in SF. In Japan dishwashers are not common AFAIK and when I was in SF partly I was just used to not using one and partly it would have really annoyed my neighbors to run it when I wanted to and scheduling around that made me just mostly forget it was there.

I'm curious what other countries they are common/not common.
Which area?
> failing to control for Vitamin D deficiency

Do you mean failing to control for the disease causing vitamin D deficiency? Because it seems that's the issue you're addressing with your proposed study design.
Much of this is written in the context of the new vfio-user proposal he linked at the end. This is a new, more flexible mechanism for implementing device emulation in a separate process. That emulation code can certainly be written in rust, providing a gradual path toward conversion.

As background, vfio-user was at least partially born of some discussions and a proof of concept last summer for using SPDK to provide virtual NVMe devices into QEMU. These are intended to be high performance devices.

Except SPDK is written in C. So maybe the title should be rewrite SPDK in Rust!
Computers can’t determine economic priorities. In a free market demand does. In a planned economy politics does.

Computers are essentially useless for a planned economy. All they can do is provide quicker orders for factories to produce the wrong things in the wrong quantities.
pandocs AST is actually a little limited, in terms of extensability, because it has to resove to JSON. The scorreia.com/software/panflute/code.html is a good python API for it.

By contrast sphinx uses docutils AST: https://github.com/live-clones/docutils/blob/master/docutils..., the documentation is not great (working on that) but it is pretty powerful.
Are you sure you're not thinking of dishwasher salt? https://fredsappliance.com/service/dishwasher-salt-use/
still happened in developing countries. people stealing metal parts from public utilities (fences, manhole covers, etc) to sell as scrap. and with it a few cases of deaths due to thieves trying to steal copper from power poles/boxes and getting electrocuted.
To your point, a confounding variable could be that diseased people go outside less (and therefore have less vitamin D)

Docker and MultiCloud Kubernetes – Free Course
I don’t think people realize that databases themselves have a caching layer internally. Redis isn’t magical, you still have to send network packets to the other server.

Even when reading from disk via mmap, hot pages are in memory.

Sometimes postgresql is faster than redis because all it needs to do is read something from memory and spit it out in the right format.
Is the intent here really to destroy? Is it really the case compliance with the law is only possible for employers like Walmart, The Gap, and thousands of other small firms in California? I'm very in favor of gig work, but the notion that the only option left is to stop work rather than hire folks as employees seems obviously facile. Notably, there's no exemption for the many other companies that operate passenger transport in the state.

Your last sentence is interesting because the entire point of a labor law like this one is to bring jobs under the remit of labor protections so that "people's jobs should be better" is something that can even be addressed.
Yes, but it would also be much harder to organise as a study and require significantly more resources.

Unfortunately, most studies prefer less work/almost equally publishable/newsworthy results :)
Probably depends on your local water and energy cost/regulations. Energy star dishwashers are so energy efficient that you have to run them basically empty before it’s better to hand wash. We really should be encouraging more countries to install more dishwashers, counterintuitively.
The book "Marching Orders" by Bruce Lee tells the story of Magic intercepts of the Japanese military and diplomatic code and reviews the daily summaries read by Marshall and other US leaders in the context of what was happening in the war at that time The point of the book, c.1995, was that signals intelligence played a huge role, but unknown role, in influencing the actions of the U.S. and U.K. And that without understanding what the leaders knew there is a tendency to overestimate their skill / leadership ability.
There is one beyond those two that has been amazingly useful : I wrote a script to type out the contents of my clipboard. That's been very useful on more than one occasion.

Train are the most efficient, simplest and oldest form of land transport. Where do you get the idea that hyperloop can even approach efficiency of a car, with all the energy wasted on high speed and keeping up near vacuum?
I think the issue he's addressing with his design is whether supplementing vitamin D would actually CAUSE infection rates to fall -

versus simply knowing that vitamin D levels and COVID infections are correlated.
A quote that combines the rules about optimization with the rules about data structures: "NoSQL databases that only have weak consistency are enforcing a broadly applied premature optimization on the entire system." --- Alexander Lloyd, Google

Also in support of Rule 5, see Eric Raymond's treatment of Data-Driven Programming:

"Even the simplest procedural logic is hard for humans to verify, but quite complex data structures are fairly easy to model and reason about. To see this, compare the expressiveness and explanatory power of a diagram of (say) a fifty-node pointer tree with a flowchart of a fifty-line program. Or, compare an array initializer expressing a conversion table with an equivalent switch statement. The difference in transparency and clarity is dramatic. See Rob
Pike's Rule 5.

"Data is more tractable than program logic. It follows that where you see a choice between complexity in data structures and complexity in code, choose the former. More: in evolving a design, you should actively seek ways to shift
complexity from code to data."

I agree in principle. That said, a law about washing hands would be impossible to actually enforce without some kind of highly intrusive surveillance, which itself would be a severe downside. But a law that wasn’t actively enforced and only existed so posters could say “wash your hands - it’s the law!” would be… fine, IMO… though I doubt it would produce much if any actual increase in handwashing.
Speaking from experience, simply wait for retirement. Then your idleness cup shall runneth over. But even that too shall eventually prove to be a bore...
