TeaVM is nice if you want to bring existing Java code depending on the Java standard library to a browser. Kotlin-js does not do that. You only have the Kotlin standard library if you target kotlin-js (well plus all the multiplatform stuff that is getting released lately). Multiplatform is the reason why this is getting interesting. There are a lot of good quality libraries that just work on kotlin-js now.

I've been using kotlin-js lately for browser development (with the Fritz2 framework). It's fine and improving rapidly. Just a year ago, this would have been a bit of a rough experience doing anything with it. But I've been using it since two months and have not really encountered any major issues. The Kotlin 1.4 release really improved things. And we indeed have a lot of Kotlin code for Android and our server so that made that an easy choice for us.

It's early days for WASM and languages like Kotlin and Java but I'm guessing that a lot of stuff is going to happen there in the next years. In the end you need more than a compilation target: you also need platform integration, development tools, and libraries. Kotlin-js is getting pretty nice for each of those and with all the multiplatform stuff coming out, you don't really need or miss a lot of the npm stuff. But if you do, it's fairly easy to deal with that as well (e.g. we integrated leaflet just a few weeks ago).

WASM support in Kotlin is still pretty immature. They recently kicked off an effort to improve support for that in the multiplatform gradle plugin. But there's still a lot of work to be done there. But, long term, I'd expect to compile to that rather than to Javascript.

> even if Robinhood had absolutely no margin buying whatsoever, they'd still have substantially the same collateral problem

They'd have a less concentrated position in GME, a smaller CNS long, and lower peak net settlement debits. All of those factors affect capital commitments. They also wouldn't have to commit their own capital for Robinhood Instant accounts with customer check/ACH deposits that haven't cleared. Currently, Robinhood Instant means that Robinhood uses up to $1k of its own funds per account to clear trades...not DTCC collateral, but rather just to pay for the trade.

In the absence of margin, Robinhood doesn't have a collateral problem in the sense of effecting transactions that may not clear. Rather, it has a liquidity problem. Big difference.

The risk to Robinhood from GME buying in margin accounts is that they would have a very large net long as a firm, and then one day the stock gaps down so quickly -- perhaps overnight -- that there is no time/opportunity to close out margined positions before they lose more than their accounts' total equity. That could leave Robinhood holding the bag on 75% of the loss assuming minimum maintenance margin.

That's why I don't believe margin to be a red herring. It directly and indirectly affects the amount of the required deposit and the clearing obligations of the firm, and also imposes a very large risk upon Robinhood in the event of a scenario where GME closes in the after-hours session at $300 on a Friday and then reopens at $0.40 on Monday morning because the company filed for bankruptcy (just an example). That scenario in turn reduces the likelihood that Robinhood can borrow from banks and investors to infuse itself with the cash required to keep its business running.

Someone else posted an article saying that additional collateral across all firms due to the r/WSB squeeze is a bit less than $8B according to a DTCC spokesman. Not sure how much of that is attributable to Robinhood. That sounds like a lot of money but it's really not, in the world of financial institutions -- especially in today's cash-happy low-rates environment. To put it in perspective, Melvin Cap got $2.75B overnight, from two people.

My own personal gripe about this whole thing is that the way Robinhood carried out its business was chiefly damaging to its own customers. I also believe they shouldn't be allowed to offer "Robinhood Instant" because it doesn't appear to line up with federal requirements for margin accounts.
> In the last 100 years nobody had lost a single penny to a bank run or default including 2008s WaMu default.

Debasement of the currency, however, has been…high.

So you didn't "lose" that dollar from a hundred years ago, it's just worth about a penny now. Where'd the other $0.99 go?
In some ways I feel like this is coming in the not-so distant future. You can already auto update releases every commit, get paid via sponsor, and receive “reviews” (issues). It’s inching steadily towards an App Store already. They seem to be adding social media features too, the user profile README being the most notable example recently.

With my understanding it's both. While it's a service that banks will hook into, consumers will have direct access to it through federally backed banks (ie all of them). Here's another link: https://www.federalreserve.gov/paymentsystems/fednow_about.h...
Yeah I get that, and I understand that that would make it difficult for individual nations to work alone. (Though not impossible - as other commenters have mentioned Australia successfully closed our internal borders.)

But you aren't in this alone. If Europe worked together, and your neighbors adopted similar policies it would have worked fine and covid would be under control by now.

The fact that you aren't on an island doesn't excuse the EU's bad covid policy decisions, at both the scale of individual countries and as a collective body.
We don't know all the potential implications. These genes will be passed on to their children. What if it causes disease?

Not to mention the splitting of humanity into separate species, based on wealth.

Nothing Real's Shake [1] was a really amazing piece of tech, especially it's ability to go back and forth from a DAG of image processing nodes to a full blown C-style (yet actually functional) compiled programming language.

Does immigration to South America is still a thing at all? For people besides Latinos.

South American countries seem to have had so many false starts. The moment they have a few decades good run, and it seem the country is finally starting to take off they either have a revolution, putsch, junta, or a communist government.
We should decide which information about us we give, and which we don’t. No matter the app we use, noone should collect information about the app usage without user permission. This should be a law right now, but the cookies were more relevant, I pressume.

I think the sentence you take issue with suffers from poor phrasing while being essentially correct. Its a maladaptive state, which makes it 'wrong' and being energy efficient makes it, well, efficient.
Another irrelevant talking point.

The whole point of inflation is to encourage investment as money is only worth something as it flows through the economy.

You’re not supposed to save money under the mattress you’re supposed to save value by purchasing assets. A hundred years ago buying roughly speaking any asset would have preserved your entire wealth or created tons of new wealth.

Wages have on average kept pace with inflation.

You keep a small slush fund for a rainy day in a savings account that at least partially offsets inflation and you invest the rest. You don’t save money, you save value. You transact money. If you’re saving money you’re doing it wrong.

This is ECON101.
I don't think you understand what "circumstantial evidence" is.

I'm aware I'm biased, but in this case the facts are in plain sight for Russian ads. A Republican authored that report. You may think yourself unbiased by saying "both sides are the same" but both sides are in fact not the same at all.

The "right" may say the same about "election fraud" but saying is not the same as having a well-sourced report, and federal investigation that netted multiple indictments and convictions.

If we actually did contact tracing, illegal crossings of infected people would be easy enough to deal with. Infections in the US are not being driven by sick people coming in from Mexico.
The article is completely wrong. Robinhood did not disable buys only, they disabled any trades that took a net new position. Existing options holders who needed to buy or sell were allowed to, and regular retail traders could also buy or sell on the other side of those transactions, because they went to closing existing open positions.

The reason you couldn’t buy but you could sell is just the simple mechanics of a short squeeze. All the net open positions were short sellers needing to buy (e.g. needing retail investors to sell) and there was just near zero volume of call options holders looking to sell (e.g. needing retail investors to buy) to close an existing position.

I feel pretty upset to see the article going into all these details of capitalization - that 100% was not the issue and at no point did Robinhood “disable buys but not sells.” They disabled creating net new positions which just happened to have a side-effect of disabling buys as a matter of the particular trading volume of various option types. If you were a call option holder, you could sell (and therefore the other party could buy).
Is it? It's pretty obvious it's not an NES controller. It's a pretty glaring oversight on the part of the devs to be honest.
TackleBox – Improved handling of PyTorch module hooks
One of my purposes is to keep living. To that end I exercise, get my heart rate elevated, try to eat better and brush my teeth. I also try (though less successfully and without much attempt) to limit my time watching TV.

I know some of my habits are awful (brushing teeth, exercise as of late, going on any walk outside) so I setup my phone to remind me every date at a specific time.

Can some of these be predetermined by an engineer? Yes! Can all of them? No.

Are not notifications intended by engineers to dictate a behavior? "To use my product" to what end various products are a means (Facebook, reddit, HN etc). I'd argue any product/system to which we join encourages us to follow it if we find it rewarding, regardless of positive outcomes (though surely the short term just look positive else what incentive exists to start?)

I was thinking last week about creating a web app to teach light pollution. And a bit of brightness in astrophotography more generally.

Context is I'd like to sketch a primary-school "atoms up" learning progression, but emphasizing nuclei. Nucleosynthesis then pulls in deep time, galaxy, and stars. But many kids, and many teachers, have never seen a sky of stars. So how might stars, largely unseen, be tied to their everyday lives?

I saw this graphic[1] go by. But it's physically unrealistic - even faint stars in darkest "1" are shown brighter than the sky in polluted "9". So how might it be done better?

Perhaps as an interactive. A slider for sky illuminance. Another for exposure (pupil dilation, etc). IIRC, retina dynamic range is similar to a screen's. Conceptual buttons, like day/twilight/night, moon and phase, urban to sea, altitude, clouds, etc. These all next to a similar sky graphic, with room left over for secondary material. So one might explore the space from cloudy day, to nights with eye and instruments, to above atmosphere, Hubble, and beyond inner-system dust scattering.

With some potential for fun stories. Like once above atmosphere, being able to see a sky of stars in the middle of the day, as long as you're not looking towards the Sun, or anything sunlit. And for addressing common misconceptions. Like the moon and stars are only up at night.

As you can see, buys make this worse, sells make it better. Robinhood could not execute buys, because it would increase the deposits they'd need, which they legally must obligate by. Sells, on the other hand, do not have this problem. They would not push the 95% boundary more to the right.

I have been trying to analyze this Robinhood story in an unbiased and objective way. My motivation is that I am interested in contemporary history and believe that what we witnessed in these past few days is a historical event.

I have a question to those here who are knowledgeable about finance and law (I am certainly not).

If my stock trading app stops allowing buying a stock, while still allowing selling a stock, even if this is done purely for technical reasons (see quote at beginning of this comment), am I incurring in market manipulation? To me the answer is evidently yes, but I would like to hear other opinions.
The other poster obviously means sufficient free testing, not advertising free tests and failing to supply them.

My favorite kind of article is "X happened, here are some relevant circumstances, author (or ppl author spoke with) think significance and possible consequences are Y"

Next favorite is "X happened" sometimes with a little context.

Least favorite "Here's some stuff about person Z who had some exciting circumstances C. Along they way Z invented / discovered X." Either finishing there or "X will transform society, rendering it unrecognizable within three years. Meanwhile, Z is considering becoming a vegetarian and is also getting married within those exciting three years."

Needless to say that least favorite is the most common. Even a listicle is better.
A company is not a static entity and its "morals" will change must faster than those of an individual. Moreover nothing says that the management of a company must act based on their innate morals. Lying for personal benefit is a perfectly valid human trait. Humans are also very good at justifying anything we do that benefits us as aligning with our moral compass. So in the end a company must be assumed to have no moral compass in the future even if it has one now. Giving a company power now based on its moral compass will just mean it has power to abuse in the future when its moral compass changes.

Microsoft and Google being recent examples of companies shifting their moral compass fairly quickly.
Updated 8-Bit Z80 Drives System-on-a-Chip Web Server
"The Z80, almost as legendary as the x86, has evolved into the eZ80 Webserver SoC (eZ80190) from ZiLOG Inc. No longer memory-limited, the eZ80's 16-bit registers have grown into 24-bit registers that provide a linear 16-Mbyte address space without a memory management unit (MMU). This capacity is greater than most competing 8- and 16-bit processors.

Code-compatible with the Z80, the eZ80's new instructions support the larger registers. Other enhancements include a 16- by 16-bit multiplier with dual 40-bit accumulators. Operating at 50 MHz, the eZ80 isn't as fast as most high-performance 32-bit processors. Yet it's more than adequate for the control and monitoring environments it targets."

Somehow I doubt the UK would have been so happy to rely on in-EU production of the Pfizer/BionTech vaccine if they'd done that. As I understand it, the UK production facilities for the AZ vaccine exist mostly because the government wanted at least one UK-produced vaccine in case Trump pulled some kind of vaccine nationalism move and restricted exports. If there was reason to suspect the EU was the one likely to do that...
The book is called "Hearing Equals Behaviour: Updated and Expanded" - can be found on Amazon - and the sound therapy is called Berard AIT or Auditory Integration Training; unfortunately there are people who claim to offer it, or have "at home" sessions they'll sell you where you rent equipment - however it's not the same high-end equipment that should be used, so "buyer beware." There are other sound therapies on the market that are reaching mainstream via well-written books, however the actual products they released don't seem to actually follow the AIT protocol and logically they shouldn't have anywhere near the same level of efficacy due to a few factors. I do know of a gentle old man in Montreal, Quebec, who was trained directly by Dr. Berard.

I liked Apple's approach when the iPhone 4 and MacBook Pro 2012 came out. Adding @2x bitmaps was easy enough for developers, and the transition was quick and painless.

Since then, however, Apple's UI has (regrettably) become less about pixel-perfect bitmaps and more about black typography on white roundrects, and almost all Macs run at a scaled resolution by default, which is then typically used to display web-based apps that support fractional scaling.

I really think that Windows' approach has aged much better. Kudos to Microsoft. We could have our cake and eat it too if Apple sold Macs with slightly higher-resolution displays, and also a 5K 27" display because other manufacturers can't be bothered.

Quite the opposite.

The costs are all already pushed to the consumer. We just don't see it, because it was impossible to see the extra 1-5% gradually added to the cost of everything as inflation also lifted prices higher.
