What "good" languages does WASM enable?

All those other dynamic scripting languages? They're DOA because nobody's going to download the entire VM every time.

What about all those nice functional languages? Very problematic because the toolchain relies on LLVM-like semantics which don't like good garbage collectors or functional programming in general.

We then get down to C-like languages, Rust, and more esoteric languages (and promptly discard the esoteric ones for lack of a decent ecosystem).

Who in their right mind wants to write a front-end in C++ or Rust? By the time you get anything done, the web has changed and you're stuck with a pile of dated code that takes too much time and costs too much money to update.

The web had a shot at a decent language with Dart (it was/is even an ECMA standard). It didn't die because of other browsers. It died because of poor web dev adoption rates.

If only Eich had been allowed to implement scheme then none of this would have been an issue.
It depends on how things are graded. On a multiple-choice test with four choices per question, someone with no knowledge who guesses randomly will get ~25%. On a true-false test, someone with no knowledge gets ~50%. On a project graded by a human, or a worksheet whose answers are real numbers, someone with no knowledge and a hard-eyed grader might well get 0%. Different classes will have different proportions of these things that contribute to the overall grade (at least, I haven't heard of any requirement that classes have the same proportions of such). The simple approach of summing total points achieved over each graded item, divided by total points possible, is straightforward to calculate, but I think there's no mathematical justification for choosing one percentage-based grading scale and applying it uniformly to all classes.
It isn't about about one off calcs but really about how the stack works over multiple operations. So you enter number 1, verify it, enter number 2, verify it, then do the operation. If you mess up, fix it now and go on. You can even go back and fix things on the stack if you notice a typo later.

Multi step complex operations is where RPN really shines. Do multi step operation 1, then 2, then 3 as independent operations. When it comes time to combine the results of the 3 operations, they are just there on the stack waiting to be used. Without RPN you had to think about saving them to memory at the end of each operation, then remember were you saved them at the end.

I had to switch from a std graph calc to RPN half way through collage and the first test I took with the 48G was a bit of a struggle. After the first 4 part question where the 4th step ended up being just combining the results from parts 1-3 that I had absentmindedly left on the stack I was sold. Just pressing + and * was SO much better then typing everything back in and verifying 3 numbers and hoping I didn't mess up a number.
All these apps and programs over complicate things. The only app I would recommend is your phones built-in timer.

Only where bandwidth and storage are constrained. If we're trying to push the state of the art, it's not going to be with a Zoom H2N.

The best music reproduction systems use lossless compression. Psychoacoustic compression does NOT get us closer to the original performance. I'm stating this as someone who gets 5 out of 5 correct, every time, on the NPR test:

You're referring to my array-of-20kHz-tone-generators experiment? Sorry I don't know the answer, but I haven't done the experiment myself; I was hoping someone here had! Where's the appeal to emotion, though? If the experiment shows a higher sample rate is necessary (that's the whole point of the experiment) it's germane.

Another note: looks like its ok for US government to have database of people inclined to protest in opposition while it isn't ok to have database of gun owners. That poses interesting question : what if a gun owner intends to use it for a protest in opposition - would such a case fall under the former or the later?
With a made up number of 99% that seems like a good argument. What's the real number?
The gold used in industry amounts to only 5% of gold mined. The vast majority of gold is not mined for "practical" use.

The part of this that's unclear to me is how much is Apple paying to Iowa as income tax, sales tax, etc? Even though apple may be selling services out of that data center, I'm not entirely sure it's taxable. It would be different if Apple were selling physical goods. In which case, high property taxes might be justified completely.

Ammonium perchlorate is a different beast. Organic peroxides are unstable as hell but as explosives their thermodynamics kind of suck. Their chemical reactivity also makes them difficult to store. TATP is popular with terrorists because it is easy to synthesize but sad material otherwise to an explosives engineer. Ammonium perchlorate, on the other hand, is right up near the top when it comes to explosive inorganic oxidizers, well-balanced and tons of potential energy. There are stronger inorganics (like hydrazine nitrate) but you never see that in industrial chemistry.

The only organic peroxide I can think of that was ever a legitimate high-power explosive was HMTD, used as a primary in strong detonators, and its chemistry was a bit like swapping peroxide for the nitro in RDX (the explosive used in C4 plastic explosives).

I am against NN but even from my point of view the innovation argument is 50% duplicitous.

I don't expect big monopoly ISPs to implement these changes with content providers in a way that doesn't disrupt end users' access. But I still don't think we should have universally outlaw this for all ISPs for all time, present and future, including nice little ones answerable to the people of a city or region.
The other duplicity is that this is not an ``innovation''. Please Mr. Lobbist. Governments have been taxing economic transactions at both endpoints (buyer and seller) for millenia and the evil tax man has always triaged the taxed at some level where it is no longer economical to collect.

If elected democrats (when NN was introduced) really wanted to help the consumer they would have done something to break up the monopoly ISPs, not this moral signaling rule says Google et. al. are less monopolistic than you so were going to pick their side. If republicans actually favored free markets they would follow up ending NN by doing the same.

> Sometimes the government has to intervene in a market (like anti-trust laws) in order to create a fair market for companies to compete. And that's OK and every free-market conservative should recognize that fact and agree that it's a good idea if they just think about it for a while.

No thinking required in this case, opposing government sponsored monopolies is obvious and shrinking those that must exist to the smallest possible size is too. Conservative federalism.
Some conservatives have favorable views of private monopolies though (stating this as a fact, not a personal opinion) and presumably they have thought about it.

That's not the definition I had in mind. What I meant is that JavaScript lacks an easy way to allow for computation that doesn't block the event loop.

We can imagine an old school cooperative multithreading architecture:

for (var i = 0; i < arr.length; i++) {
someCalculation(arr[i]);
yieldToNextEvent();
}

but JavaScript does not support this. Instead you have to awkwardly re-structure your computation in CPS or an equivalent to do this sort of thing.
You should expand the service (or start a new one) into other categories of physical goods: manga, novels, video games, figurines and other merchandise not found anywhere else outside of Japan.

Let subscribers pick their preferred categories and allow them to choose the amount of money they want to pay each month + shipping costs,

then you go out and buy random things from one or more of those categories (in order of user preference), and keep a record of which items you sent to each customer, to avoid duplicates.

Social fluff: Let users post on-site reviews of the items they receive from you.

Ideal outcome: People discover the uniqueness of Japan, share it with their friends and other users, and you help spread some joy and pocket the change.

Almost definitely light response - orchids are pollinated by a wide variety of insects, including night active moths.

Well, the alleged spokesperson from DisruptJ20 (the site in question) seems to be condoning and supporting it as quoted in WaPo :

https://www.washingtonpost.com/local/public-safety/protester...

He said that what appeared chaotic was purposeful in its symbolism and that vandalism at a Starbucks shop and a Bank of America branch were executed as attacks on capitalism and corporate greed.

“That’s what we’re making a strong stand against. I think that all of Washington, D.C., feels that way, even if they wouldn’t express it in something that results in a limo getting burned,” said Lacy MacAuley of the District. MacAuley is the spokeswoman for DisruptJ20,...

Not sure how trustworthy WaPo is as it part of the mainstream media but I doubt they completely fabricated that quote. And from the videos I've seen, there weren't a lot of peaceful protestors pulling these rioters away or trying to stop them in any way.

To be honest, I'm learning a lot from the comments on this thread. I appreciate climate change skeptics speaking up because I know it's not a popular position to take. I also appreciate where everyone has added highly credible citations to back up their claims.

For those who struggle to understand skeptics point of view take a look at Michael Crichton's interview on Charlie Rose. This was the first time I came to appreciate the views of climate change skeptics: https://www.youtube.com/watch?v=Vh4dIkEyfd0

Essentially he says yes the planet is warming but the impact that will have is unclear and models suggesting a high degree of certainty are not being honest. (I don't think this is the same FUD of cigarette companies as some have suggested above).

An even quicker way to understand skeptics is to read this blog: http://theparadoxproject.org/blog-1/2017/6/6/the-tribes-of-c.... The 5 points on climate change, and where skeptics vs. scientists differ, is clearly laid out.

Essentially liberals and conservatives largely agree on the facts but differ on the policies that can help.
A while back I made a partial emulator for Z5 (a version of the virtual machine Infocom games ran on) that recompiled the game dynamically to Javascript[1], and I remember while pouring over the dumps coming across the fact "You're holding too many things already!" depended by a random number. I never checked whether it could actually fire, though! I assumed it was vestigial, with the "Your load is too heavy" message in the same function.

Another quirk I came across was how in the Canyon View, on many emulators when you "climb down" you are greeted with "The xc ec knwall munz doesn't lead downward." It turns out the Solid Gold edition has no name for the "down" object, which probably didn't exist in earlier versions, and emulators don't tend to check the text length field for the object (0 in this case) because the string encoding uses something like null-termination. Text is encoded in 5-bit blocks, explaining how the random data stays within the alphabet. Whatever emulators do, it's still a bug in the game.

[1] It was an excuse to figure out how to make an Emscripten-like relooper, to figure out how to simulate blocking calls ("continuations") using exceptions, and to learn about the design of the Z-machine.

Edit: I guess I should mention for the "xc ec knwall munz" quirk that the directions are all objects, and "climb" is meant for ropes and stairs. I believe what is happening is that you can go down in the Canyon view, but "down" isn't the vehicle which will carry you there.

Tests are great. No harm in tests.

I just don't think that we have sufficient evidence to conclude that using type systems to aid the development of concurrent code actually leads to better concurrent code. Therefore, I err on the side of not using the type system for that purpose so that I can use it for many other things that I think it's really good at.

(Just take a look at JSC's source code if you want to see our extensive reliance on those areas of C++'s type system that we can use to get hard guarantees. It's not that we don't like types. It's that we use types in an evidence-based way in those places where they actually help us catch bugs.)
Precisely. It's a race-to-the-bottom.

This implies that large corporations act like normal people, which really isn't the case.

The shareholders of publicly traded companies expect exponential growth, and if the managers and owners don't provide that growth, the board of directors kicks them out and replaces them with someone who will drive that growth, regardless of the effect on the workers. When corporations naturally behave sociopathically, it's only natural to treat them differently from normal people.
