> Maybe dial it back a bit with the challenge to point at literature. The literature has not really caught up with the existence of WASM yet.

It wasn't me who claimed that WASM is "obviously" a register machine, despite the inventors saying otherwise. They even explicitly state that they decided against a register machine. I guess it's then reasonable for me to ask on what definition of stack vs register you are basing this opinion on. Let me be clear: I was not asking here for literature about WASM specifically but a definition of register/stack machines that supports your claim.

WASM's instruction encoding is very much based on a stack machine. Even with the initial limitations you mentioned I don't think it qualifies as "obviously a register machine". As already mentioned in multiple comments those restrictions were already lifted with the multi value proposal.

I understand that there is a grey area, but simply claiming "obviously a register machine" doesn't seem right to me. Implementation-wise WASM is a stack machine even if it needs/needed locals to be turing-complete.

There's something so aesthetically beautiful about these images. The repetition and contrast. And the rarity of the scene.

It all seems so... vulnerable though. That's a lot of expensive craft in one spot.

Sorry, I should have qualified that fully. I meant clinical sensitivity for RT-PCR for SARS-CoV-2 for samples drawn from throat swabs, specifically. I know that my local hospital is only taking throat swabs, not nasal swabs; and all the press photos I've seen for testing in India is of throat swabs.

Remote teams: How to build a culture of accountability
Envoy is written in C++, not Go.
I am not sure if it is a good idea to host SFUs* fairly centrally in cloud data centers. Wouldn't it be cheaper to build a network of SFUs that deal with traffic as locally as possible? That keeps backbone traffic low and and cloud traffic costs sane at the expense of having to find all these colo sites. I reslly have no if AWS or GCP could even handle all that incoming and outgoing traffic in theory.

*SFU: selective forwarding unit - the node in a video conference call that receives and resends all the video streams between participants.
dead people's copyrighted work sues for copyright issues all the time... not sure how that would help.
Yes, and I think that's the problem. The infrastructure is actually a cost for Uber. It's better to have less infrastructure. I have sometimes the feeling the infrastructure team at Uber is trying to build the tower of Babel to touch the heavens or something rather than considering that the end goal is giving people rides and not building more infrastructure.

I think people should recognise that the taxi market has an advantage. It's a distributed system and a market. Taxis organise themselves.

If you're going to replace an entire market with a centrally planned system and a giant electricity and compute eating machine then you better have something to show for it in terms of efficiency.
Ask HN: How do open source products set product direction?
Working on product teams in companies, its pretty easy to understand how product feature creation and priority is set. Its a mix of customer wants/needs, company directives, and measuring internal priorities.

In the decentralized world of an open source product however, there isn't this top down culture to go out and define the thing.

How do maintainers or contributors of open source projects decide what features to prioritize or what markets to enter next?
Completely spot-on. Too many "all-in-one" platforms are just too rigid and with AI infrastructure tooling still in the early stages, the companies that adopt modular products will be able to capitalize on new advances.
If you have to ask it's probably still pretty niche, almost by definition
The underlying current in this article and others recently posted on the topic is that a return to in-person schools will happen next year.

Districts and states need to be asking themselves: "What if that isn't possible?"

There's a lot we don't know about the virus. How long does immunity last? How long will it take to get a vaccine? What happens if multiple flare-ups occur as people rush back to work, parties, cruises, and the rest?

There's a growing sense that there's light at the end of the tunnel. That light was achieved by strict measures that are melting away at a blistering pace. Nobody knows what happens when you start loosening up.

One possibility is unavoidable: there are more active cases today by at least an order of magnitude than there were when the restrictions were put into place. Exponential growth hasn't been suspended just because people need to return to normal.

Officials interviewed in this story didn't indicate what will be happening after instruction ends for the year. It might be a good time to assess what worked and what didn't, then develop a plan and do teacher training for distance learning for Fall 2020.
Why is that propaganda?

As a parent in a crisis situation, your job is to provide emotional stability for your kids. So you need to ensure your own physical and emotional health first (see also: "put your oxygen mask on before helping others"). So if "home school" has to take a backseat to showing the kids that "this is different, but this can be healthy/interesting/stimulating too", then so be it. And some days are good homeschool days, some are less. Take each day as it comes.

However, juggling work and home school is just impossible. In a two salary family, someone needs to go on disability or take unpaid leave or whatever. Your kids need you right now more than your boss does.
I'm in California, if that helps. Looks much better now too, good article, I've wanted to do this in my home for a while.
> In data science, most time-travel issues are worked around using bitemporal data modeling: which is a fancy way of saying "add a separate timestamp column to the table to record when the data was written".

Not quite, this is "transaction time". You also need "valid time" to be truly bitemporal. Recovering the database as of some point in time is not enough to answer questions like "when will this fact become false?" or "when did our belief about when it would become false change?", because you didn't preserve assertions about the time range over which the fact was held to be true.

In terms of implementations, ranges are better than double timestamps. They provide their own assertion of monotonicity and can be easily used in exclusion indices.

I found that Snodgrass's textbook was a good introduction to the concepts and it's available for free: https://www2.cs.arizona.edu/~rts/tdbbook.pdf
>The US runs it's elections like a game show because everything in America must be prime-time entertainment.

You might get downvoted for the snark but you're not wrong at all. I remain convinced that entertainment value is the most important qualifier for a President in modern times, and that probably goes back to JFK. Americans no longer trust government and don't believe in political leadership but they love celebrities and a good show.
I meant, it's cheap until you get locked in with oracle.
Just to support your argument, according to Wikipedia only one human disease has ever been eradicated: https://en.wikipedia.org/wiki/Eradication_of_infectious_dise...
It is thus unlikely that Covid will be eradicated, and much more likely that it will be endemic. My best guess is that when people talk about Covid being "eradicated" they are making a mistake and really mean something like "there is a vaccine"...
I see, thanks for the explanatory response. When the GitHub issues reference was made, I was somehow expecting connecting to GitHub and supporting a column-based board like format.

I guess I've only worked with issues and mostly in a board with columns format, except in Asana which I took a long time to get used to then didn't like because page transitions could be so slow. I think I'm not the target market.
This isn't necessarily an unrelated controversy.

Excessive record sealing, secret legal opinions, pay-walled public records, and the fact that Federal courts are only available to large businesses while the rest of us are forced into arbitration, are all closely related issues.

There is a good faith argument that copyright term extensions are but another example of the common thread connecting those issues.
> Does the equation change if you get the best teacher in the world via video vs just an average teacher live?

That's a really weird way of thinking about it. You're completely ignoring the relational aspect of learning and focusing exclusively on the artifact of a particular presentation of some content. You also seems to be assuming that everyone learns the same way without variation. Commodification and mass production are improvements in a lot of areas, but not all.

I don't think you can rank the teachers of the world from best to worst, when often the best teacher is a good-enough one that understands you.
It's not specifically what you're talking about, but individual plant management is becoming more and more popular. It's done with drones - not the blade type but the wing type. They use multispectral cameras and interpretation that ends up showing you things like malnutrition, over/under watering, crop wear, disease, insect infestations etc.

There has been a similar thing for decades, from planes. But drones mean much more regular intervals and much higher resolutions.
What, exactly, was unsubstantive about that comment? I'm flabbergasted that after what the market has done in the last couple of months, especially given the OP, that anyone is under the impression investors have any idea what they're doing.

>into the world. Binge-watching shows on Netflix for a month straight contributes to as much carbon emissions as a flight from London to New York

I was under the impression that one of the primary costs of airfare was fuel? I get that power plants are using a cheaper type of fuel than jet fuel, but some back of the envelope math suggests that netflix must be getting their fuel/energy for at least an order of magnitude less then airplanes are getting their fuel/energy. It implies that if you binge watch enough shows on netflix they're actually making a sizable loss on energy costs alone...

What are your plans WRT Coral? I noticed there's a work-in-progress Go implementation. Is it going to supercede Kademlia eventually?
Having servers in a colo is pretty much what "having a datacenter" means for the last 10 years or so. I'm surprised at your viewpoint of "having a datacentre" meaning only having direct ownership of the piece of land on which the datacentre resides. That's a pretty rigid and outdated definition.

Tremendous Trump Telescope
Show HN: Parallel.so – looking for early stage users
I was expecting something along the lines of The Final Telescope v2 or The New Final Telescope v2.03
Man, I worked for them, I know the score :)

And that's precisely what I said: they just use the law ("contracts"). Legitimate businesses don't want problems with the law. It's more effective, for Oracle, to carefully draft (and subsequently enforce) legal documents, than to add some rigamarole that will only make life harder for legitimate clients and their own support ops.
I just tried today. Its super fast when compared to RLS. Types inferred are better. I hope one day we will have release v1.0.
orbitdb is a distributed database built on IPFS - looks like they have a python http client: https://github.com/orbitdb/py-orbit-db-http-client

In California, the answer to that last question is proposition 13 cutting the legs off of school district funding in the face of a rising population. That's why there are always education bills, because schools have been short on money for 50 years.

There are some benefits to public education that I think many on HN gloss over due to their privileged perspective when they make sweeping generalities.

Fitness and access to a nurse is a benefit. For some kids, gym class is the only time they are physically active, and a checkup in the nurses office is their only source of medical care. Access to role models is another function. Sometimes a teacher or coach is the only positive role model a kid has in their life. Another benefit of schools are that they are a safe space for kids from abusive households.

Families in poverty also rely on meals from their school district. In the face of this crisis, LAUSD is still making meals for students and their families, at times giving away 500,000 meals in a single day (1).

That was concerning, so I finished what I was doing, restarted in macOS Recovery by rebooting while holding down Command-R, launched Disk Utility, started First Aid, went to make dinner, and promptly forgot about it.

One thing I've learned over the years is that if you suspect a hardware failure, especially to the boot drive, there's a very good chance that a reboot is not going to succeed. As the article shows, the "true end" came not long after that. Good that he has backups, and that's probably why he could even forget about it.

The drive supposedly has 128 MB of cache memory, but it’s only 5400 rpm, and while its speed has never been a noticeable problem while making backups, it’s painful beyond belief to use as a boot drive. USB 3.0 might theoretically be capable of 625 MBps, but when I tested the drive in Blackmagic Speed Test, it averaged just 20–25 MBps for both read and write speeds.

Maybe SSDs have spoiled us, but I'm still surprised just how much disk activity newer OSes produce, especially upon boot; or perhaps it's just the non-default stuff loaded upon startup by apps, which can easily build up without affecting performance if you normally have an ultra-fast SSD. I know someone who used a regular USB flash drive (probably <10MB/s) with a "portable" copy of XP for several years as a basic minimal development environment, and it wasn't actually slower than a HDD of the time; in fact, it was quite responsive, probably due to the much better random read performance of flash vs. a spinning disk.
Wasn't it fairly common in the US' past that military service was an option if you didn't want to go to jail? I don't know for which crimes this applied, but it was definitely a thing.

Yes, you're correct -- an omission on my part. You need "valid time" (otherwise it's just "uni"-temporal modeling).

Thank you for the link to Snodgrass' book. I've not seen a formal book on temporal modeling in SQL before, so this is fascinating.
My Chinese wife receives phone calls like this all the time. Either it's DHL telling her she has a package to pick up (in a completely different state) or it's the consulate asking for some information. I guess my phone number got in with hers somewhere along the line as I've also received a call or two like this.

I lived in South Florida for a while. That art style is so recognizable that I immediately knew where the Apple ad came from, though I didn't know the artist's name.

How do you even begin to quantify the 'likeness' of one piece of art to another though? In this case it sounds easy enough since they consulted with the artist beforehand, but what if they ripped off his style without ever talking to him, how do you prove it's a copyright infringement?
Yeah, that is about the worst possible way to do it. If you can't do a hard delete for whatever reason, the right way to do it is to set a flag that prevents any activity on that account. They can keep the name in order to prevent anyone else from stealing it, but still delete all the profile data attached to the account.
This paragraph neatly sums up the "gold" myths of Bitcoin:

> This means that things that are hard to create, and whose creation can’t be faked, have value. Bitcoin, like gold and other precious metals, has both of these properties. Mining Bitcoin requires large amounts of electricity and computational power. In fact, the Bitcoin network uses a similar amount of energy every year as the entire country of Venezuela.

Actually a distributed ledger is not the same as a rare metal:

1. Unlike gold, Bitcoin can cease to exist. If nobody keeps the blockchain alive, it doesn't exist any more. Try to make gold disappear from the ground!

2. Unlike gold, the operators can decide to increase supply. Or reduce it. By orders of magnitude. It's a code change. Try that with gold.

3. Forks are abundant. Good luck trying to invent a new element.

4. The economical benefit of Bitcoins is much too small to explain the energy use. It can't even keep up with the transaction count of a small town. The energy expenses can only be justified by expected future return. This is actually where Bitcoin is somewhat comparable to gold as a valuable. It's just that gold actually has real-world uses besides acting as currency. So we know the price for gold won't go to zero. Unless of course we find ways to defy our current physics!
What PayPal does or did (according to stories I read a while back) was freeze the funds and then simultaneously advertise a loan to the customer. So I guess we could subtract the interest rate charged by other lenders for that kind of loan from the rate that PayPal would charge, to get an estimate of the risk that PayPal believes it is mitigating when freezing people's funds.
We need to the govt to bail these folks out.

I notice that your code supports the 'name' custom section as expected, and furthermore you support a few other custom sections too - 'dylink' for example. Where did you find the documentation for these sections? The reason I ask is that I don't believe the official webassembly specs talk about those sections, so I guess they are somewhat compiler specific perhaps?
From the Wikipedia article (emphasis mine):

>In 2010, the United States Department of Agriculture (USDA) reported that 23.5 million Americans live in "food deserts", meaning that they live more than one mile from a supermarket in urban or suburban areas and more than 10 miles from a supermarket in rural areas.[6]
