K/KDB is a pile of shite. It's loved by quants and managers in financial firms. But it's hated by programmers who actually have to write code in it and deal with shitty code written by quants. K is full of arbitrary restrictions (two many global/local variables - what is it, 1970s?) and crazy quirks (function closing brace has to indented, otherwise you'll get a weird error). All in the name of performance, of course. The error reporting is insanely cryptic. It doesn't tell you what caused an error or even where it happened. It just tells you something like "'rank" - and that's it. Once your code grows beyond 10 lines, you can kiss your sanity goodbye.

And let's talk about performance. K is inherently single threaded. If you have a powerful 96-core machine, it's of no use to you because your K code will be using only a single core. I've seen numpy easily beating K when numpy uses MKL library with automatic parallelization.

There is a reason K/KDB is not very popular outside of a certain domain. It's not because it's proprietary and it costs a fortune. It's just bad.
This is great. It might be able to be used by programs like me cleaner.
There is still a TPC_RR occurrence in the post.
Coronavirus – Why we need to act now
I'm not an epidemiologist - but this article gives a very convincing and logical argument why we need to act now to prevent COVID-19 from spreading.

The test may be more likely to be a false negative in the early stages of infection. As a result, it may be better to quarantine people who have been exposed without testing them and only test them after they develop symptoms. Otherwise you may be telling someone who has been exposed and is infected that they're not, and then they don't bother to quarantine themselves and go infect other people.
In the US, the default state of affairs is that you have to pay for all health care, even if it's to protect other people from you.
I have long been a fan of the 4d fixed universe. If you think of fractals you can get a hint at how everything is interrelated. As you indicated, the fundamental issue is why we experience the passage of time. I dont think it's an illusion, but the most important question.
No point in wasting a test on someone you're assuming is and treating as infected.
Absurd compared to what?
There is no such thing as “intrinsic” value. Value requires an evaluator.

Maybe you mean that bitcoin doesn’t have value outside of its ostensive monetary value. Bitcoin has that too. It can back up data to thousands of locations and be censorship resistant and have a verifiable timestamp.

Where do you work that medical professionals with ILI symptoms don't meet screening criteria?
How great must someone's economic prospects be before to earn before it's no longer OK to be homophobic, racist, xenophobic and voting and voting for someone cynically exploit their ignorance?

How is their misery somehow a reason that makes them required to vote for not just a Republican no matter what but the worst possible one who is not even a conservative but looks our for absolutely no one's interests on any side except his own fame and wealth?
>until I realized most of them said things that sounded nice without any link to the foundations of the hard physical sciences.

Part of philosophy's job is finding a solid epistemological basis for the "hard sciences", and what claims such sciences can legitimately make about the world.

>I realized that philosophy is a little like theology, and the real truths are much darker.

Philosophy has plenty of "dark truths". What are nihilism or moral skepticism, for instance, if not philosophical theories that negate the meaning of life and morality? Besides, to justifiably throw out philospohy because its claims are inconvenient to you (e.g. by "sounding nice") would require some philosophy to begin with.
I'm curious to know if anyone who regularly uses Rust could speak to a theory I have on the language. I'm by no means an expert but I've dabbled enough to know Rust is I think going to be far more important to the world than it is already.

I'm planning to dive back into it, but this time I'm going to attempt to do all of my programming in such a way so as to not require 'lifetime' semantics.

Not 100% sure how easy it would be to do so, but the theory is that maybe writing code that needs lifetime semantics is an anti-pattern? Rust has just given us the tooling so we can confirm that the "style" we are already writing our code in adhere's to Rust's guarantees...
That is a very interesting use case with everything that is happening right now. We are exclusively focused on computer vision but I agree that would be very valuable for a situation like this.
The title I'm seeing on the article is "Startups Are Abandoning Suburbs for Cities With Good Transit" which seems to more accurately represent the study compared to the current HN title: "New businesses are choosing cities with good public transportation: study"
That is the idea. They're saying that, in practice, the Authority is anti-freedom, and freedom is the enemy.
You would prefer that prosecutors be able to indict people without any checks? Grand jury proceedings are secret to protect the innocent.
It's optics. Every Canadian is being told that you won't be tested if you are asymptomatic. If he was to get tested, it shows a disparity in the system.
I will probably go for testing as my family is starting to show symptoms.

The helplines are telling people to not get tested and remain home. The whole travel ban is some bs (even my town had people coming from places like china 4 days ago literally). Exams are still going on. All metrics are fudged including the number of testing facilities capable of doing the tests.

This is gonna be horrible. Local hospitals are filled with people. This is not even close to some of the worst corona hit places. All have pneumonia or some other kind of respiratory problem. Heard from my dad when he got supplies from the medical store.

They are not doing ANY community testing at all and officially saying that there is no community spread without evidence.
It would be very surprising if they quarantined in time or strictly enough to prevent the virus from entering in significant numbers. Even societies with highly centralized control structures (Iran, Japan) weren't able to keep it out. I doubt a decentralized country like India with huge amounts of human movement without and within could do it, just as the US and EU couldn't.
The anime is good, but the original visual novel is much more detailed and offers several endings. 11/10 would recommend; it's the only time I can say a video game brought me close to tears. The Steins;Gate visual novel was the perfect gateway drug into otaku culture for me the first time I played it, especially since it included a glossary of terms related to anime/manga that grew as the story continued.
That is the version of the |> operator I'm familiar with from Julia.
> It's a matter of life and death, and the strategic objectives are black and white.

To my mind, that is the whole point of the wartime analogy. It _is_ life and death (for your company) when you are at war.

Sometimes you need shocking analogies to get the message across to employees; if you have weeks of money left in the bank, you need everyone to be ruthlessly focused on the strategy that has been decided. No time for picking daisies or fixing tech debt when you have weeks of money left! This shocking analogy aims to provides focus and clarity when it's most needed.

> When Steve Jobs returned to Apple, the company was weeks away from bankruptcy—a classic wartime scenario. He needed everyone to move with precision and follow his exact plan; there was no room for individual creativity outside of the core mission. In stark contrast, as Google achieved dominance in the search market, Google’s management fostered peacetime innovation by enabling and even requiring every employee to spend 20% of their time on their own new projects.
I've experienced that with some Chinese folks on the streets of SF.

But I've also experienced it with some Americans from NYC, and just assumed it was an emergent trait of people living in heavily-populated high-density cities.

Edit:

There's a similar phenomenon I've seen sharing space/food with guy friends who grew up with multiple brothers. The baseline aggression and competitiveness is visibly turned up a notch.
Lol your best attack was a product that wasn't killed off. Good that I called you out.
The media hates this one and millions/millions do too because they can't think for themselves. They just plug their heads into the media of their choice Fox News, CNN and MSNBC and get fired up while they make millions/billions.

Further even Pelosi in her speech today wasn't having any of the media's crap where she basically says we are working together on this no need to make it anymore then that. Good one Pelosi.

Also is there a guide to follow on how to deal with the coronavirus?
The Democrats may well fail to rescue the nation from Trump, but the responsibility lies first with the man himself, his party of late, and his supporters who have no problem with the vile behavior and ignorance he proudly displays every day.
I was on call that night, working for Webcom, a forgotten pioneer of the early web. Working so our servers at Exodus data center in San Jose would keep functioning.... Nothing happened :)

Of course though, because we had spent the previous few months setting clocks forward to see what broke, and fixing it.
Yep. Superdeterminism as a particular physical hypothesis has nothing to do with a philosophical notion of determinism or debates about free will. The latter is really the subject of metaphysics which by definition is not physics.

It is like mixing implementation details of a particular Python script with a theory of programming languages.
Oh, to be clear - the person with symptoms hasn’t had patient contact in a long time. But the fact that they can’t get tested causes another asymptomatic person who does have very heavy patient contact to be quarantined for 14 days.
White House asks tech leaders for help with coronavirus response
> ... because they are getting tested anyway. Symptoms or not

Not in this case.

> Trudeau will also stay in isolation for 14 days, but on the advice of his doctors, will not be tested because he has no symptoms.

I’ve had several hotels cancel on me when they overbooked.
From what I've heard, a number of IT departments used it as justification to dump legacy systems.

For example, at a former employer of mine, a big justification for getting rid of the IBM-compatible mainframe and a lot of legacy systems which ran on it (various in-house apps written in COBOL and FORTRAN) was Y2K.

In reality, they probably could have updated the mainframe systems to be Y2K-compliant. But, they didn't want to do that. They wanted to dump it all and replace it with an off-the-shelf solution running on Unix and/or Windows. And, for reasons which have absolutely nothing to do with Y2K itself (the expense and limitations of the mainframe platform), it probably was the right call. But, Y2K helped moved it from "wouldn't-it-be-nice-if-we" column into the "must-be-done" column.
I've so far been quite happy with the iCE40UP5k[1] based dev kit I got, though there are a lot of options out there[2].

The iCE40 FPGAs are a bit whimpy compared to Altera and Xilinx offerings from what I understand, but I really liked the idea of an open-source toolchain[3][4] being available.

To get a taste without committing cash you could just use a simulator[5], which I imagine you'd be using a fair bit anyway as it allows you easier access to the internal state.

As to actually programming, I've found the following resources useful. I started with Verilog mainly because code-gen tools like nMigen[6] generate Verilog, but for writing by hand it seems VHDL is preferred.

Anyway, links, first off some exercises to get going[7]. Introduction to Verilog[8], also has a nice general overview of HDL. Details of how non-blocking vs blocking statements in Verilog works[9], quite specific but was very informative for me.

There's also quite a lot of activity over at Reddit[10], and good experiences over at the EEVBlog forums[11].

As I said I just got started so no expert yet :)

Apparently college students wait till after they pay off their debts to vote.
The bug was y2036, which he said we knew was a problem even then. It is definitely still a problem.
Yes, it definitely is problematic to have everything "just in time", but, the problem with this virus is that it's basically a DDoS attack on the medical system. Wuhan is not a poor city. They average 7.38 hospital beds per 1000 persons by 2018 data. In comparison, the US averages 2.4 beds per 1000 persons in 2016. On top of the strict quarantine, China had to build two 1000-bed hospitals in 2 weeks, convert multiple public spaces into field hospitals, and send thousands of medical professionals from all over the country to get the situation under control in Wuhan. I shudder to think what would happen if we fail to mitigate the spread here.

Lol Google was one company till 2015. Alphabet and Google have the same CEO. Just shows your biases in trying to prove your point. It was Google who pumped in money in Waymo. Have fun using ddg and Firefox.
Counterargument #1, #2 is due to the government's stance towards China. The government is trying to win back China's (so called) friendship, which was shattered when the U.S. deployed THAAD there.

South Korea was able to handle this not because the government did good, but they experienced the MERS outbreak in 2015. Legislative measures to prevent outbreaks were made then. (plus the lesson of impeachment I guess)
Came here to say this. Great channel and explanation of the Y2K.

It won’t hit insurance companies because it’s the type of risk that’s offloaded into the reinsurance market. Extrapolating from retail insurance products to bespoke policies for sophisticated well capitalized businesses is an error. Pontoon boats on Lake Havasu aren’t insured for piracy. Lloyd’s covers container ships for it because that’s what they do.
You're not wrong, but it's amazing that on the one side you have one VP son's enjoying some sweet nepotism and on the other you have an entire family, but somehow Biden is worse because everyone just expects and excepts that the Trumps are corrupt so it doesn't matter. And of course the electorate can't find a third alternative.

Assuming the entire org is using a captive proxy with an installed CA, identify/isolate every upper-level management person's system(s) in some way, and reroute their access to all internal applications through a deliberately horribly misconfigured HTTPS reverse proxy running TLS 1.0. Their modern browser will explode.

I think war may be more similar to business than you think it is. And it may not be very much like the war you imagine in your head.

You think there is singularity of purpose in war? Every general, every battalion, every captain, every soldier has their own interests at play. It's a miracle of leadership that those can be put aside long enough to fight side by side.

Crushing the competition sounds like the right move in war. But then why have so many armies failed to subdue and control the local populace? Could it be that treating the conquered with respect, as partners, as humans, might be more effective than sheer domination?

And how sustainable is war? It depends. In WW1, soldiers at the front lines for more than a few days often suffered shell shock from the severe tension, nonstop terror, and unbelievable pounding that must have felt like it came from the bowels of the Earth. In other wars, there is no traditional front line, and soldiers are deployed for months or years. And they're not in 100% fight mode the entire time either.

War and business are not the same. But they may be closer than you think.
Because they are breaking the law by violating zoning codes which we put there for a reason.
> you have a first-order universe in which these mysterious entities operate with effectively infinite precision behind the scenes, to create a second-order universe which has limited precision in practice

There are analogues to this in mathematics, for example, our formulation of the Fourier transform has limited precision but the physical phenomenon it relates to has no reason to be limited.

He also warned that his arrival might have changed the outcome. He covered his bases.
It's a valid comparison in the sense that both Singapore and Chinese governance structure allows extremely despotic interventions that other representative forms of governments cannot. The broad point that the countries that responded effectively so far either have the benefit of authoritarian mobilization capabilities or still have vast populations that experienced living under the shadow of authoritarian regimes. I don't think we'll see similar levels of compliance in the west, on top of actually having very difficult borders to police.
South Korea traces the movement of everyone who tests positive, puts the movements online and tests those who were exposed to someone positive (this is in the article I believe). It's a massive effort but with the world economy at a stand-still, what else do people have to do?

North Italy has a population of 27 people btw so the 10K that are registered as positive as a drop in the bucket.
Why would you think this is disfunction? He's acting on advice of a doctor and in any case, it seems to be a wise use of scarce resources. He's in isolation for two weeks so what does it matter? Save the test for someone who needs it.
Meanwhile, the parent poster was talking about not wanting to move to the US, and this isn't much of a contradictory statement on those lines.

That's still USD at the end of the day. That just sells it to somebody else who wants to use it as an investment (unless things have changed since I've last looked into it).

It would be hilarious if the bible predicted a war over vegetable oil.
I completely agree that the comparisons to war are way overdone. However if this is your perception of war, then there is a lot that isn't really accurate.

1. If everyone doesn't go home it's a crisis, it's NEVER ok

2. We work unbelievably hard to try and find "viable, co-operative alternatives" and, at least in modern warfare, there is almost never a singularity of purpose

3. "Crushing" your competition hasn't worked since WWII - even then we worked to rebuild afterwards. Building Partnerships is a key tenet of modern warfare

4. On the ground negotiations are a daily/standard practice in the shit even if they aren't formal diplomatic negotiations

5. Low-Intensity war has been the standard for over a decade now too...and being in a warzone for a year at a time is not uncommon

So there's things to be learned on either side and it's worth really understanding both to have a full picture.

Spoofing. I start up faceb0ok.website or whatever and theme it to look identical to Facebook. I then make a viral Facebook post that tells you Facebook will send you a $50 Amazon gift card if you click on this link. You click, then instinctively log in with your Facebook credentials because you can't tell that you're not on the real Facebook anymore. I now have your credentials.

Man-in-the-Middle (MITM). I'm at the same coffee shop as you and I've taken control of the router. You request your bank's web site and I'm able to route that request through my laptop, fetch the web page, and return it back to you. You log in to the web site. The connection is still encrypted, but the termination of the encryption is actually happening on my laptop. You log into the bank site. I now have your bank account credentials.

Cross-site scripting (XSS). Your site allows visitors to embed content (for example, message board posts) without that content being properly filtered. I use that to embed some JavaScript that watches for users using the log in form on your site and send those credentials to me, or sends the content of the cookie of users already logged on.

Poor hashing. You mentioned that above so you're probably aware of it already, but it's disturbing and surprising how many sites don't have this figured out yet.

I'm not sure what problems network dropouts could cause, at least in terms of security - which is the big problem here.

Of course there's more, but this is what comes to mind. In summary, I strongly suggest you don't try to reinvent a new authentication system. use one already in common use. It's probably already fairly battle-tested and validated for correctness and security. This goes for most other types of software as well.
