As a South Korean currently living in the US, let me add my perspective:

1. North Korea ceased to be an "existential threat" to South Korea a very long time ago. According to Wikipedia, South Korea's GDP is 1.4466 trillion USD; North Korea's is estimated to be 25 billion USD. That's a factor of 58.

For comparison, USA's GDP is 17.95 trillion USD. Cuba's is 77.15 billion USD. That's a factor of 233.

So, see how much Americans feel threatened by Castro these days, and multiply that by four.

2. The only way they could be a major threat is if they go suicidal. However, they are not ISIS: Kim Jong Un has no intention of becoming a martyr. (Of course, he has a lot to gain by looking like a crazy, unstable dictator who could start a war any day: North Korea is the master of this mode of "crazy diplomacy".)

However, in the extremely unlikely case that Kim decides to go full nuclear, ironically, all these nuclear missiles would make little difference to South Korea. North Korea has millions of soldiers and enough conventional weapons to burn Seoul down to ground. Adding one Hiroshima-size nuke or two will be... well, like adding one Hiroshima to the whole Pacific War, I guess.

This makes about half of South Koreans go "meh" at the news of yet another nuclear test. They can already kill us, and if they do, they will be killed, too. Everybody knows that. Nothing has changed.

Of course, America does not like having such a "rogue" nation with a nuclear missile that can hit San Francisco, so all this posturing is basically targeted advertisement for the US. I think they are saying, "Look at me, we have nukes now, so you will be sorry if you attack us!" They're trying to cut some kind of deal with the US. (Of course it may actually provoke US into some "preemptive strike," so it's a very risky gambit, for them and also for the whole East Asia. But when did they ever care for human lives anyway?)

Unfortunately your realization is empirically unsound, and the problems of “every teacher you know” have as much to do with lack of available expert teacher attention per student and standard expected teaching styles and school structure with substantial friction/latency in feedback and huge amounts of wasted time as with inherent student ability.

Start here http://web.mit.edu/5.95/readings/bloom-two-sigma.pdf but then there is a vast literature (thousands of studies and other research papers) exploring the general topic of math pedagogy. Some approaches and some teachers are radically more successful than others, given comparable students.

If you hand me one of your 20th percentile students who is struggling but willing to learn, and give us the same amount of time which would otherwise be spent in a classroom for a year of one-on-one face-to-face time, with the student also spending a typical amount of time working independently, I can have them outperforming your 80th percentile students by the end of the year, without issue. The difficulty of course is that direct mentoring by an expert tutor is too expensive for society to be willing to pay for at scale.

The main reasons that your teacher friends are stuck is because (a) many if not most of their students are unprepared before they arrive in any particular course, which is largely down to structural social factors and school scheduling inflexibility, and (b) the combination of lectures and independent work with inadequate feedback are for the average student a terribly inefficient and ineffective way to learn. Neither of those has all too much to do with biological predestination or whatever.
Mandatory XKCD: https://xkcd.com/1172/
Is saying "I'm sorry" an admission of guilt somehow? Genuinely interested.
Not really. If a fair price for your company is $10m today or $40m in a year if you do well, there isn't a good reason to invest at $40m today (or even a discount like 20% off $40m).

An analogy: Amazon is $1k/share today. Let's say you think there's a 30% chance it will 3x in the next year. Would you like to invest at $2.5k/share today? The answer is No because that has negative expected value, and you'd rather just wait a year and invest at $3k/share than investing at a small discount to $3k/share today when the stock is worth much less than that.

Also, the time horizon doesn't change the misaligned incentives here. Because I get in at next round's price, I would prefer for that price to be lower.
Those are valid limitations, but current 3d imaging techniques I know of are either with photography, laser scanning or touch probing. All of the above also face those limitations.

My initial interest was that it would bring the cost down a lot, but they don't seem to bring great precision and they require a moving robot with at least 3 axes which is unlikely to be very cheap for precision material.
In fact, it's probably helpful for them to practice that before they have to on the job.
It sounds like you needed a music player with a better interface. I seriously doubt that a very convenient (fully? mostly? partially?) hands-free interface requires a microphone uploading what used to be private audio to servers you do not control.

> brought music back into our lives, in a big way

That's great, but you should be able get a similar benefit without giving up your expectation of privacy. Normalizing sending the audio from formerly private areas - even if you are not currently saying anything other than "Alexa, play ${random_pop_song}" - will eventually move listening devices across the bright line established in Kyllo v. United States[1][2]. The SCOTUS opinion: (emphasis added)

>> "Where, as here, the Government uses a device that is not in general public use, to explore details of the home that would previously have been unknowable without physical intrusion, the surveillance is a "search" and is presumptively unreasonable without a warrant."

When a technology is* in "general public use", a warrant is no longer required to use that technology in a search. If Echo (or similar) becomes common enough for people to start assuming the average home may contain a microphone that uploads to a 3rd party, the expectation that a home is private. Music is important, but was that particular convenience worth undermining the 4th Amendment?

Can someone please explain, from a practical perspective, what does RISC-V give your average user?

Right now, I want a secure laptop. I can't by one (nothing which doesn't require binary-blobs), so I decide to make my own.

What do I need?

1. An instruction set.
2. A factory.
3. Customers (and a lot, so power of scale can make it somewhat reasonably priced).

All RISC-V could help with is #1. I won't have to contract from ARM and will save some cash there.

But I'll still need to build a factory and deal with economy of scale.

Moreover, what will prevent companies from leaching off RISC-V and patenting improvements. As I understand, there are so few foundries right now that that can easily cross license patents from each other and prevent upstarts from breaking in (so you'll have a situation where the industry leaders end up organizing themselves into something which looks like ARM or Intel/AMD)?
Buoyant Raises a Round from Benchmark, Peter Fenton Joins Board
How much medical/pharma R&D spending happens in the U.K.? How much happens in the US?

It’s an apples and oranges comparison because The US effectively subsidizes the advances enjoyed by other countries.
The point of the strike would be to destroy threats to Seoul prior to an invasion (i.e. removing the obstacle). As even you noted, the US wouldn't strike and wait as that creates more problems than it solves.
> Again, that claim is easily refuted by considering the state of medical spending in the US

One could argue that the medical system the us has right now is inefficient BECAUSE of the current legislation. It is a very regulated industry, it hasnt gotten to this point because of its unregulated capitalism.
"School is about the advanced stuff, not the basics" is the call of good students, often ones who learnt the basics from their parents. It's also kind of popular with bad students, who think that they might suck at the basics but have untapped powers if they were doing something else.

It's nice, vague, and populist. Everything thinks they know how to do critical thinking. Everyone thinks they know how it could be taught. I suspect most people think that they have above average critical thinking skills. As long as they don't have to agree on how or what critical thinking is, everyone can agree it's a good thing.

The other one that's dumb is "you learn best when you teach yourself". Sure, if you are really super-interested in something then you learn better, and tend to teach yourself a bit, but correlation is not causation.
> So, at this point, every language was scaled to very high concurrent loads. What does that tell us?

Just like any language vs language debate each one has benefits for various particular use-cases. Any meaningful comparison of languages must be prefaced with the use-case scenario.

One of the strongest use-cases of Erlang/Elixir has always been building large distributed apps that need to scale (async web apps, telecom, chat servers, messaging mobile apps, etc). The ability to build these large distributed systems are baked into the very primitive parts of the language and standard library - to a degree that few other languages can compare to it, if any.

With Erlang/Elixir you design ALL applications in a way where scaling is rarely an after thought but rather a natural extension of the program.

> Beam is modeled on actors, and offer no alternatives. Java offers all sorts of models, including actors, but if actors are the currently most fun and productive way to scale, that doesn't matter.

People often make the mistake of trivializing Erlang/Elixirs as merely programming with actors. It's development not only predated the actor model but it also goes well beyond that to being the standard programming style you use when developing any program when using the language - the same way Rails embraces MVP. When this is fundamental part of every Erlang application then the means of scaling to a large distributed system are also a fundamental part of each program.

This built-in scaling is gained without any significant costs in terms of development time but also provides many benefits beyond scaling, such as highly modular and extensible code. There are real benefits even if you don't plan to scale to a large distributed system. similar to Rails it creates a predictable program design which makes joining new projects easier and deters NIH syndrome that is far too common in Java/C++/etc. And ultimately, regardless of what you are building, it provides very high performance by default for the type of async style applications that are popular on the web today.

So the key point here is not that the end goal was achieved (that you can scale) but how you get there.

It's a very personal preference of course, but I can't recommend higly enough to try mapping caps to command. My wrists are very grateful.

As a vim user I use Ctrl+[ for escape. I like it because it is a standard system mapping, so it works everywhere. Further, many systems (incl macOS) have standard options to map caps to control, so I can carry the habit pretty much everywhere, even if using someone else's computer temporarily.

> Yet the "farthest star" article says the farthest star is only 9 billion light years away

I think you completely misread the article. This is the farthest star we've been able to observe directly at its normal luminescence, as in, not a supernova. Granted, it is due to gravitational lensing.

The article never says this is the farthest star that exists, simply the farthest (by far) that we've been able to directly observe.
After 20 years of buyin (15+ routers) and searching for a wifi router that "just works"TM in large house scenario I finally found the ASUS AC5300.

https://www.amazon.com/gp/product/B0167HG1V6/

It has 3 radios on board 2x5ghz and 1x2.4ghz.

It has a mode that allows you to use a single ssid across all 3 radios. It uses QOS to dynamically switch each devices to the best radio for at any moment.

I purchased the same device for a small retail business and it works amazingly well in that setting too.

Highly recommended.
Most of this seems pretty standard for Linux distros; python2 and python3 installed by default, ability to install venv through `python -m`, other versions of Python and various packages available in the repositories. Is there something I'm missing here?
Honestly, if the answer to that is that they invest in you and you use their money to buy google cloud ml services, and you go out and find customers, that doesn't sound bad.
I hadn't heard it explained this way before, but it explains so much.

So, for example, if I came up with a better sorting algorithm, I couldn't patent Luca Sort, but I could patent using a computer to run the Luca Sort algorithm? Or am I misunderstanding?
Pensions have largely gone away, replaced with 401k's which for the average person will not have the yield a pension would and just makes business' look like they care without actually making any real investment in a person's future. The stock market is largely a rich man's game as you have to have the money to invest so their are only the ones' on top who really have the money to put into a system and can afford others to manage it to ensure financial gain. The 401k is worthless if you don't know how to manage it and the employer is only to eager to outsource that to lowest bidder who taxes people with fees for doing nothing and promising even less.
I'm sorry, but I'm extremely skeptical of this. All too often people on the internet like to lie just to generate buzz or troll. This smells of BS.

As a warning to all the Soylent consumers
The observation that native S Koreans are unaffected by the threat and US S Koreans are stimulated by it is interesting.

My observation is that we tend to remember the oversimplified ends of the spectrum and that almost everyone exists more in the gray area between the poles.

It's likely that those who live in S Korea are used to hearing many small nuggets of news about the N Korean conflict, so they are desensitized by it. The US news gives N Korea very little time in the headlines except during the occasional announcement when they did something dramatic, which trains Americans to think that everything N Korea does is dramatic. Also, the US doesn't have television shows that treat N Koreans (defectors) as humans -- we only have shows that talk about N Korea in the context of spies, military, or some other aggressive/nefarious way.

> the narrative I hear is of doom and gloom, NK is just weeks, if not hours, away from nuking me in SF

Where do you think this narrative comes from? The US corporate media companies push that because it's a juicy news story (even if there's nothing "new" about it). The DoD and State Department also manage to coordinate their their message when appearing on news shows -- through current and former military / intelligence leaders. It's not something I interpret as an organic feeling that the average person has. People on the street still talk about Trump, the economy / stock market -- not so much about NKorea or KJU.

> to avoid paying overhead, which is irksome

Why is it "irksome"? Pretty much every administrator treats grants as revenue (i.e., department X brought in Y grant dollars last year). I wouldn't want to give someone a grant if half of it goes to fund the university's operations.
A buddy just PoC'd a key binding system for OS X to do arbitrary complex remappings like this (exactly to facilitate nonstandard esc, ctrl, hyper usage), represented as one or more state machines similar to this syntax:

STATE1:
caps down:
ctrl+alt+cmd down
STATE2
STATE2:
caps up:
ctrl+alt+cmd up
press esc
STATE1
after 1000ms, default:
ctrl+alt+cmd up
STATE1

This would allow us to layer, say, half qwerty on top of hyper with the same system. Or map caps to esc and ctrl, and map caps+shift to hyper, or a non-meta like tab to hyper.

Also could do state transitions on external events (like new app focused), and execute templated applescript.

An easy state machine to build would be this, which would prevent keypresses after focus stealing:

STATE1:
new window focused: STATE2
STATE2:
after 250ms: STATE1
default:
drop keypress
STATE2
There hasn't been a true war between great powers since WWII, and that's more likely due to nuclear bombs than free trade agreements.

Mutual defense agreements don't matter if the US invades North Korea, the US is not the defensive party in the war. And it's easy to say that all of these sides would back the US now, an aggressive war in the region could change a lot of alliances.

Invading North Korea is not a sane option for the US unless China consents. The best case scenario sees China allowing it while preparing for a future conflict, and all out war is very possible.

> while my Java apps take 2 minutes to start up, have several hundred millisecond HTTP response latency and horde memory

To be fair, there's no reason JVM servers can't have sub 10ms responses, that sounds like a problem at the application level like you mentioned (spring). Nothing wrong with a JVM language if it solves your problem.
Directly from asm.js FAQ (http://asmjs.org/faq.html):

Q. Can asm.js serve as a VM for managed languages, like the JVM or CLR?

A. Right now, asm.js has no direct access to garbage-collected data; an asm.js program can only interact indirectly with external data via numeric handles. In future versions we intend to introduce garbage collection and structured data based on the ES6 structured binary data API, which will make asm.js an even better target for managed languages.
