Do mathematical things exist independently of the minds who conceive of them ? The ontological status of abstract things, right? My point is, materialists deny these kinds of things. That's disembodied spiritual bunkum and it has no place in modern thinking.

Then, later in the day they're perfectly happy to deal with things just as abstract and non-corpreal without feeling like they're cheating in any way.

The fact is the philosophy of science has not caught up to the advances in science as any good QM thread here will show.

>Does the law of non-contradiction exist?

The fact that neither of us can answer this (assuming we both agree to what it implies about the world, which actually, heh... I am not totally convinced of, but that's another matter) ... anyway the fact that neither us can answer this in the way you meant it is an interesting fact in the same family of interesting questions as raised in this discussion.

The quarks->atoms->molecules->neurons->brains->experience (consciouness) chain of causality, which is the standard model of reality and has been for a few hundred years now, is broken at both ends by which I mean the descriptive philosophical ideation at both ends is to no one's real satisfaction.
Nobody (serious) is suggesting that everything will be permanent. What's being suggested is that several smaller changes made during the crisis, especially the ones involving legislation, will never be un-done.
Yeah, but it does seem like this could be a retail (via online sales) product. I don't really see many e-ink commercially deployed around me, and I'm in the bay area. I think the company(ies) controlling this tech ought to try to do anything to make their products more accessible/used.

> Upon a positive test of a user for COVID-19, their Diagnosis Keys and associated DayNumbers are uploaded to the Diagnosis Server. A Diagnosis Server is a server that aggregates the Diagnosis Keys from the users who tested positive and distributes them to all the user clients who are using contact tracing.

Is this scalable? Earlier in the document they mentioned that the tracing keys are 16 bytes long. Let's assume that there are 3 million patients in a country. That'd be 48 megabytes each user has to download and process per day to check whether they've been in contact with an infected person (processing involves calculation of 144 HMACs per tracing key). I don't think this is feasible at scale and one can't avoid thinking about area recognizing diagnosis servers.

E.g. Smartphones of patients would upload not just the diagnosis keys, but also the areas (county, district, something like that) they've been inside during that day. Then smartphones querying the diagnosis servers would have to send the areas they are interested in. But it's easy to see that this approach is then quite privacy invading. On the bright side, this info is already available to carriers so it's already a sunken cost so to speak.

That's known in Haskell as the List monad. There's a function to transform Maybe (like Rust's Option) to lists. In Haskell, lists can be infinitely long.

Regarding the IO monad, Simon Peyton Jones has an article explaining why they went with that rather than streams. Sadly I don't remember what it was, but it had something to do with proper interleaving of input and output. (Btw, in a way, the IO monad is a stream of commands to the RTS.)
Yeah, FDR was so effective that when the supreme court ruled his actions unconstitutional, he threatened to pack the court with his own appointees and now there are practically no limits on what the federal government can do.

My understanding is that no, they can’t, because the virus does not reproduce in mosquitos.

Similarly to HIV, it is theoretically possible for a mosquito to feed off someone with the virus then within minutes feed off someone else, be killed, and the infected blood contain enough remaining particles to cause an infection... but to my knowledge this has never been shown to happen in practice.

I’m more concerned about stray cats. It has been shown that felines can both host 2019-nCoV and get COVID-19.
We could, though, It's not practical today, but it's definitely something that humanity could achieve, especially with technology like this.

Even if it's not the most important thing we could do, eliminating influenza and the common cold would be pretty fricking awesome.
The book "Men Who Stare at Goats" (no idea about the movie) is a terrifying look at the weaponization of the technique turned on the American public.

You have to read between the lines: most people believe the CIA really was exploring use of ESP against the Soviets. Very, very few understand that it was a successful propaganda operation against the American public. Those few also have a clue how we were collectively convinced that invading Iraq would be a really good idea.

This is not about "embarrassment", I was talking specifically about bisect. Bisect needs every commit to be usable; and this, in turns needs either mutable history, superhuman programmers, or manual file copy. So do many other things -- for example, cherry-picking is almost impossible if the feature is spread over tens of commits.

I agree about not changing published history. But you don't need Fossil for that -- gitlab, github and even vanilla git all have ways to make master branch "fast-forward-only", which eliminates this problem. And if you are worried about "here-today, gone-tomorrow commits", git has a per-branch flag to prevent rebases and warn you loudly about them.

I agree that working in the open is good, but again, there is no need for Fossil for that -- that's what "sandbox" branches are for. As long as you don't push incomplete work to master, you can share it easily.
That's not the secret sauce, in the same sense that keeping source closed doesn't usually improve code quality from a security standpoint.

The other counter is there are 26 operators of the F-16. Frankly it would be easier both in practice and legality to get cooperation from some dude in Pakistan or Venezuela than a US citizen who can at least sorta be watched over.

Most of the tactics are not terribly advanced in the sense of some mysterious secret martial arts kick that defeats all. Most of the time battles are won logistically long before the fighting starts. Everyone in the business kinda knows what F16s do, not any more of a secret than knowing what Mig29s do, the struggle is always having enough resources in the right places at the right times to do anything about it.

Something that often surprises civilians is most US military manuals are freeware and have always been that way. If you want to learn how an Army Brigade Combat Team operates, you don't join the KGB and steal documents, you just download FM 3-96 and read it. This is why actual veterans get annoyed about fictional hollywood military stuff; if you don't understand the role of a BCT's information operations officer sufficient to portray one in a movie, its just sheer lazyness to make something up instead of simply reading the FM.

Its all part of the interesting strategy to handling massive public communications networks; half a century ago you could have an edge if it depended on having a secret sauce. Now that anyone with a web browser can download the official F-16 flight manual your strategy for having an edge relies on other forms of secret sauces.

A good analogy for the problem is that excellent world class scientific documentation exists for weight loss and athletic performance, yet most people will not train in those areas. Olympic athletes are not high performers because the textbooks for weight lifting are kept secret and only for their reading.
“Intel cores can run in one of three modes: license 0 (L0) is the fastest (and is associated with the turbo frequencies written on the box), license 1 (L1) is slower and license 2 (L2) is the slowest. To get into license 2, you need sustained use of heavy 512-bit instructions, where sustained means approximately one such instruction every cycle. Similarly, if you are using 256-bit heavy instructions in a sustained manner, you will move to L1. The processor does not immediately move to a higher license when encountering heavy instructions: it will first execute these instructions with reduced performance (say 4x slower) and only when there are many of them will the processor change its frequency. Otherwise, any other 512-bit instructions will move the core to L1: the processor stops and changes its frequency as soon as an instruction is encountered.”

Great info from here: https://lemire.me/blog/2018/09/07/avx-512-when-and-how-to-us...

Be careful to benchmark real loads as there are perverse interactions e.g. “Downclocking, when it happens, is per core and for a short time after you have used particular instructions (e.g., ~2ms).“ so a function using AVX512 can affect the speed of unrelated code (similar to thermal throttling).

What exactly are nutjobs going to do with any of these weapons?

We've had cases of nutjobs getting their hands on tanks, or building their own armored bulldozers, and going on rampages. It's a pain, but it's not a complete disaster. These vehicles aren't invincible. They generally get stuck somewhere, and then the police break open the hatch and shoot the nutjob. Tanks really can't do much by themselves besides drive around and run into some things (or over them, but again, you have to be careful or it can get stuck, break a tread, etc.). Tanks armed with 120mm cannon rounds, of course, can do some serious damage, but private individuals aren't allowed to own that kind of weaponry at all.

It's the same with an older fighter jet. What are you going to do with it? Fly it into a building? Sure, that'll be worse than flying a Cessna into a building, but still, it's not like a WMD. Even if you could fully load the 20mm cannon, you're not going to do that much damage; they don't hold that much ammo anyway (only enough for something like 5-10 seconds of sustained fire I think). Yeah, being able to drop a bunch of 500lb bombs would be a disaster, but again, you can't get that stuff.

Yes, if Elon or Jeff wanted a nuclear-armed ICBM, the government would certainly stop them. Building a rocket is one thing, building a nuclear warhead is something else entirely, and is not something trivial that just anyone can do. Iran (an actual nation-state) has been trying for some time and still hasn't succeeded as far as we know. It takes a lot of facilities and special materials to build something like that.

Go with your gut. The higher resolution means that the text looks more like "real ink", but I'm not sure if this is a big deal for you. For me, the refresh rate is just fast enough that I don't notice it while I'm editing text.

One important thing to consider, which maybe I should have shared in the other post: I don't really enjoy using the mouse on the e-ink display, because of the refresh rate. It's doable, but noticeably choppy.

If using the mouse is important to you while you code, go for the faster refresh rate!

The lower resolution might actually be nice too since it might better match your other displays.

I don't worry about that. We're backed by IBM Cloud now, there was that $34B bet placed last year, there's all sort of cross selling going on between IBM and Red Hat. I imagine we'll see more and more Red Hat software integrated in IBM Cloud services and offerings, and then, we'll have a Red Hat Enterprise Linux which will look a lot like Amazon Linux (which appears to be based on RHEL & CentOS).
It would be pretty nice if as an industry we could figure out how to apply the DRY principle to interviewing. It's the biggest waste of time for both for candidates and interviewers that we need to establish whether a candidate with 20 years of experience can write a for loop every time they apply for any job.

> You do need to understand your access patterns well, and develop migration plans when they change.

This sounds like a minor issue, but it's a huge operational pain. Migrating a data structure to accommodate new queries involves operations and application changes, both substantial. Migrating all data in a consistent way is either extremely hard or requires significant downtime.

In my opinion, for most cases, this problem is significantly worse than doing joins in first place.

The SEC Rule That Destroyed the Universe
Your link claims we spend ~$8,000 per child.

There’s a $2,000 per child federal tax credit. That’s 25% of that number just off the bat.

Here’s a link which claims we spend $12,000 per child in 2005 just on education. [1]

Based on what we spend on education, which apparently is the second highest in the world... I have a hard time concluding we are under-investing.

Keep in mind the majority of spending on elderly is social security, which is a mandatory retirement program that every worker paid into.

You know, I screwed up an interview that was using your technique once.

The person gave me a piece of paper with a program on it with a number of problems, and asked me to find them. But she was too involved with my problem solving, sort of looking at me as I worked through it, and I was sort of off-balance.

I was almost about to say wait, let me do this on my own, but it was hard for me to be sort of rudely assertive because it was an interview.

Meanwhile other interviews where the person would give me a problem and ignore me would have me doing fine.

For starters, I would assume that most people's daily rotating keys could easily be fingerprinted based on identifiable patterns of movement that could be picked up by any number of municipal devices people come into contact with throughout the day.

In order for contact tracing to work as advertised, each person's device has to keep a log of daily ids that they contacted that has a TTL of at least a few weeks. That means that whenever a law breaker gets arrested, law enforcement would be able to confiscate their device and be able to construct a list of everyone that they've been in contact with in the last few weeks.
Yes. However, I don't think it's accurate to characterize Lippmann's assessment of the public as "meddlesome". It's true that he was an elitist, but Lippmann's brand of elitism stemmed from the empirical observation that governing a large population is clearly too complex for even a representative democracy to do well (and is certainly more difficult than proponents of democracy are willing to admit, if not impossible). Unlike most forms of elitism, his view of the public as incapable of governing itself was not rooted in ideas about their moral inferiority but in the acknowledgement that it just isn't functionally possible for them to run the show. This observation led to three conclusions (which IMO are correct): 1) That democracy at scale always regresses to partisanship, 2) The idea that "the people" actually govern themselves in any real democracy is largely a farce, and 3) That a system of "representatives" and bureaucrats running the show is itself elitist.

I think you misunderstand me. I’m not claiming that a pandemic is unprecedented. I’m claiming that a pandemic in the post modern economy is unprecedented, as is a prophylactic shutdown of 1/3 of the economy.

That being said, my point is that economic predictions are especially difficult given that we’ve never seen this before.

For comparison, consider the many economists who at the time expected the depression to reappear after the demobilization following WWII. Despite their good intentions and good data, they too were dealing with a unique situation, and they turned out to be very wrong.

(And don't get me started on the blurring of the "sci-fi" genre. Superhero movies are not sci-fi. Sharks attacking are not sci-fi even if they have lasers on their heads, or six heads, or swim through ice. Fast & Furious isn't sci-fi. Harry Potter isn't sci-fi. (WTF Sy-fy channel!?) Zombies aren't sci-fi. Nor vampires, nor bigfoot, nor giant animals. Godzilla isn't sci-fi. I'm just ranting... ignore me. Swords and magic: not sci-fi. ...okay I think I'm done...)
No, that doesn't seem rational. Only the distance 1 people should be alerted - that's how it works in existing contact tracing systems.
