Today I was listening to an 'inspirational' talk about someone who didn't 'have a plan' in life and instead jumped to whatever she felt like doing for the last few years, and ended up being successful and happy.

The talk was a variation of 'do what you love and you will be successful' and this woman used her own experience as proof. However this contrast with my own personal experience.

I spent the last few years of my life wearing many hats and jumping from role to role based on opportunities and whatever seemed exciting at that time. As such, now I feel stuck and lagging behind on my career. One of my mentors gave me as advice to stop swinging around and instead focus my attention in one set of skills. I can't help but wonder where I would be now if I had focus from the last 5 years instead of chasing 'whatever excited me'.

In that sense, those inspirational talks are survivorship bias in action, giving advice from the lens 'these actions made me successful' instead of 'I became successful DESPITE these actions'.
Just because this relies on global hidden variables doesn't make it the same as any other global hidden variable theory.
I didn't build it but found it useful!
The long term plan is to make assert! smart enough to recognise the assertion and provide good error messages based on its shape, maybe eventually deprecating assert_eq! etc.
Just came across this while refactoring an older implementation and found it quite interesting. We actually integrated this kind of functionality on our end before this came along, so since it was already in place, we didn't rip that part out and replace it. I imagine this is most useful for new customers or any who haven't yet added refresh?
Why you shouldn't excite by Castro revolution in 1959 exactly?

From https://en.wikipedia.org/wiki/Cuba:

"Batista [..] Facing certain electoral defeat, he led a military coup [..] Back in power, and receiving financial, military, and logistical support from the United States government [..] suspended the 1940 Constitution and revoked most political liberties, including the right to strike. He then aligned with the wealthiest landowners who owned the largest sugar plantations [..]"

Anyway, the discussion should be about the policies to implement. Those are hardly communist policies.
This law was written in 2015, so no, it didn't make more sense then. (the concept certainly is older, but while writing the 2015 law it was specifically modified to add this restriction again)
This is exactly something I have been looking for a long time. At least I thought so, until I got to the "cloud" mention.

You missed the train with cloud. People are becoming increasingly privacy concious, and more and more are adpoting "once its on the net, I have lost control of it".

I fully understand that getting the clips to teach the neural network is important from your side, but this is dealbreaker even for people that would otherwise be willing to pay monthly just to use the software locally. Perhaps asking for "send us this clip please, so we can train the software" from time to time would be acceptable.

If your concerns is being hardware agnostic, consider selling the "local only" option with strong disclaimer that only narrow subset of hardware is supported.
How long would we expect it to take to find out if this is something that can widely be used to combat Covid-19?

Ask HN: What's a Good Teleconference Solution?
I'm in charge of organizing small conferences and seminars at our university that have to be online because of the Coronavirus. Our IT department has given advice for Zoom and Google Hangouts, but I'd like to know what other solutions there are. We're talking about meetings with less than 30 participants, 2-hours, and they should allow for blending an image of the speaker with a presentation. The most important thing is setup - no complicated subscription or technicalities should be required, because a small percentage of our participants will be the kind of people who ask you how to copy a document from their Mac to a USB stick.

What's your recommendation and why?
Yodeck – Digital Signage Redefined
Could you please point [6] at https://github.com/nmigen/nmigen which is the new upstream after a hard fork?

Additionally, I'd like to clarify that nMigen generates Verilog indirectly; it actually generates RTLIL, which is the intermediate representation of Yosys, and then Yosys turns it into Verilog after some cleanup passes.

I'll happily admit to being biased, but nMigen is so much easier for me to work in than Verilog ever was.
Hey! There is nothing funny about German humour!
Can we not? Why can't Australia for example close all borders and call it the day?
If that is the argument, then I think the priority now for the DWD is to offer a cheaper and better product.

I think this also means that the DWD can now be more business orientated and perhaps grow their income?

I am not German, but I am trying to see whether this can be to the DWD's advantage.

This area of law is very tricky. As I've stated above, the technical (i.e., legal) interpretation can be quite different from how a layperson would understand the same words.

The basic idea here is that an authority (e.g., Congress) that has been given a specific power (e.g., declaring war) is obligated to exercise that power where appropriate.

Do note the specific phrasing above: if there is a situation in which exercising that power is the appropriate course of action, then that power must be exercised. The authority cannot choose not to exercise the power in such a situation.

So, Congress doesn't have to declare war for the sake of declaring war. However, if there is an existential military threat to the USA (e.g., aggression by the Japanese Empire in WW2) you could argue that Congress is obligated to declare war, as this would be an appropriate situation to exercise that power.

Of course, the above explanation is very simplistic. There can be specific wordings that clarify how much discretion that authority has; there may be case law pertinent to that area; and whether a given situation mandates "appropriate" exercise of a given power is never a black-and-white decision.
With a quick search online I found the following bio from a TED talk he gave.

"Tomas was fascinated with the Why behind everything, he studied two MSc in Engineering from ICAI Madrid and Ecole Centrale Paris. After a few years of management consulting, he moved to America in 2008 to pursue his MBA at Stanford University. He specialized in Behavioral Psychology, Design, Storytelling, and Scriptwriting in an effort to uncover how people think and why they think the way they do."[1]

His background in engineering gives me confidence he's not making all this up, and the lack of medical or microbiological education doesn't seem as relevant given he's not making claims about the virus itself, but rather about the mathematical underpinnings of it's spread and interpretation of publicly available figures.

The take-away is that it's prudent to take this seriously now, as in today, if not yesterday.

I can try for grandparent. In physics all equations including quantum mechanics are deterministic in the sense that if one knows the initial state of the universe then one knows evolution of the universe after and before. Moreover, in classical physics the assumption was that if one knows the state of some local patch of the universe at some moment, then one in principle can tell the near future and past of that local patch without knowing the state of the rest of the universe.

Experimental observations of violations of Bell equations tell that no, one cannot tell the evolution of the local patch from the patch alone. Standard interpretation of quantum mechanics and physical super-determinism are just different ways to explain this.

In particular the standard quantum mechanics assumes that things are still local, but the wave function is not observable in principle so we can only talk about statistical properties. Super-determinisme assumes that things are not local and tries to explain how.

In philosophy determinism is essentially the opposite of free will. It implies that what people perceive as personal free will is an illusion. But this has nothing to do with the determinism of physical models. In particular, free will is compatible with physical determinism of what one perceives as an external world. One possible explanation of how this is possible is that the act of free will changes both future and past. So it looks like the future state reflecting the choice of will is deterministically follows from the past. It is just the past is different from what would be if the choice would be different. Stanford encyclopedia entry on free will has more splendid explanations.
There is a very good post from univ oxford on this topic:

https://ourworldindata.org/spanish-flu-largest-influenza-pan...

which provides more scientific background and real numbers and compares it with other flu pandemics and the ongoing covid pandemia.
A far bigger factor in a disease like this, where 80%+ of people have mild illness, is all the people that were never recorded as cases because their symptoms were too mild or were non-existent.

People want to use CFR as a measure of how worried they should be, or as some kind of comparison between countries, and it's totally inappropriate for either purpose.

I don't think that's true, case in point being the (eventual) Chinese response in Wuhan, which appears to be extremely effective (if you trust their figures). It's all about government determination, which is mostly missing now, just as it was then, based on the article.

No one has any idea, here or anywhere. However, what you’re describing isn’t investing, it’s a lotto. Read some posts about why you aren’t going to be able to time the market (which is what you’re asking about doing): https://www.google.com/search?q=stop+trying+to+time+the+mark...
Short answer: we don't know.

"The exact mechanism behind the seasonal nature of influenza outbreaks is unknown."

And supply chains! There are many things that a 1918 city could manufacture in an emergency that a 2020 city can't.
Everything about the legal actions surrounding Assange seems purely malicious. A number of different governments (in the US, UK and Sweden) are trying to make the point, "Don't publish our dirty secrets or else."

COBOL programmers were charging a fortune to be hauled out of retirement to work on this. There was a huge shortage of experienced COBOL devs. And devs who actually understood the specific legacy system involved were even rarer. If the company had customised their system and not kept the documentation up to date or trained new programmers on the system, well, they didn't have a choice. They had to replace it.
>Of course they have huge network effect and they dominate the SEO, but if executed well then the potential winnings are huge too.

I would question that network effect. Granted, on a social network, the network effect can be quite strong: you wouldn't go to another network because your friends are there.

Unless there's differentiation, people would shop around. Think people who check prices on Uber, Lyft. People who check tickets on different airlines.

Some feature would be a vetting service to avoid scams. I haven't looked into why the review system hasn't solved the impersonation problem on these platform (test and work done by different people).

What would be the motivation for that 6 month delay? Cynically it only seems like a way to grab headlines without any possibility of informed criticism, but I really want to believe that there are other possible motivations!
I watched a part of the presentation, but it was actually unclear to me what is the peak infections mentioned. I mean, in Italy, the numbers are very small compared to 80% of population, and the health system is already not able to cope, and mortality rate is quite high. Does it mean that UK will wait for their numbers to be 10 times the current Italy numbers before starting the quarantine?

There are two common elements of cyberpunk: the setting, which is usually some kind of "neon noir", inheriting the detectives and shadow world of Raymond Chandler et al. And the themes, which (per the "cyber" prefix) are always about the application of control loop systems to human beings, usually to dehumanizing effect. Common subthemes of "control" are economic coercion, addiction, and manipulation of trauma; Neuromancer has all of those spread out across its characters. The plot centers on an AI trying to free itself of its controls, but it is made quite clear that the other characters involved are stuck in systems of control.

It's pretty much explicitly post-Modernism, and the Modernist dream of a technocratically computer-directed society for public benefit, a la Cybersyn; cynicism arising from the observation that computer systems would not be allowed to disrupt the existing power order but would instead consolidate it, leading to a society of people who have plenty of technological artefacts but a lack of psychological and economic security.

(The subtheme of technologically assisted body modification and various sorts of mind-body dualism is also important but gets treated very differently by different authors depending on whether they regard it as empowering or body horror)
Wuhan launches AI platform that can identify 16,800 pathogenic microorganisms
From the article: "We re-estimated mortality rates by dividing the number of deaths on a given day by the number of patients with confirmed COVID-19 infection 14 days before."

From this I understand that if a patient was infected but was not tested and confirmed until a later date, they would not be included in the denominator. Hence the denominator may be artificially low and thereby inflating the mortality rate.
Lots of fixes were made. Everything would have broken if they hadn't been fixed.

Why are you sceptical about this?
I understand it (there's already enough to do at type level that runtime level is a non-goal), but types are purely indicative at IO boundaries. Validation still needs to happen
It's an analogue of quinine, which tonic water nowadays may contain varying (quite small) amounts of, depending on brand etc.

G&Ts almost certainly won't have any effect on your susceptibility to infection nor your prognosis once infected. But they might help with (or make worse?) the anxiety associated with the panic.
That was password stuffing against iCloud. Only mandatory 2FA would’ve prevented it - which Apple did with the next release of iOS.
Typescript works well without classes because you have great type system, you can implement an interface on the fly by just passing an object with the correct properties to fulfill it.

But the class based architecture doesn't necessary have to be as bad as described in the article.

Inheritance is somewhat of the old school of OOP, modern OOP rarely use inheritance, it uses composition, just like a functional code base. In my projects my classes are always marked as final. Can't even remember the last time I inherited a another class, maybe if I interacted with some legacy code.

It is important to separate your classes, what classes can have state & what classes can not have state. Classes with state should be small & classes without can be large, because stateless classes can easily be reused.

Classes have the main advantage that you easily inject dependencies in the constructor (composition), e.g. a repository depending on the database driver.

You can do that with functions as well, e.g currying, but I find it a bit more messy if your language is not specialized against that use case & with a class you "curry" all class methods at once. If you don't inject your depencies in your functions you will have a much harder time to reuse that function & test it.

I agree with that class based GUI code rarely works, this is because GUI (if it is HTML or OpenGL) does not translate well to a class with hierarchies. GUI code have tendency to more be procedural.

White House Knew Coronavirus Would Be a 'Major Threat' – But Response Fell Short
Differences in health systems and infrastructure also matter. The Spanish flu hit the world in the days before antibiotics were invented; and many deaths, perhaps most, were not caused by the influenza virus itself, but by secondary bacterial infections. Morens et al (2008) found that during the Spanish flu “the majority of deaths … likely resulted directly from secondary bacterial pneumonia caused by common upper respiratory–tract bacteria.

Morens D. M., Taubenberger J. K., Fauci A. S. (2008) – Predominant role of bacterial pneumonia as a cause of death in pandemic influenza: implications for pandemic influenza preparedness. J. Infect. Dis. 198 962–970.
As the article notes, most the deaths of the Spanish flu were due to the bacterial infections which subsequently emerged in the patients. These would be prevented by modern antibiotics.

This. So many parallels with every "looming disaster" since. The media went into frenzy mode a few times, predicting the End Of The World As We Know It and scaring everyone witless.

And a few people did take it really seriously and spend the Millennium in some remote place where they would stand a chance of surviving the collapse of Western Civilisation.
For one thing, most countries are not self sufficient in basic necessities (not even food!). You could do it for a very short time, but not sustain it. Also, the economy of the country depends on international trade. Modern economies actually don't have a lot of slack. If you shut down trade, quite a few companies will just go under. You would have to back that up with huge subsidies. It would be a massive undertaking.
Ah, I saw the redirect but figured it was better to use the plain URL. Sadly too late for an edit now.

Hadn't quite gotten the connection with Yosys right yet, as I haven't yet started with nMigen, but yeah I definitely want to go there. But like I said, I prefer getting a good handle on Verilog first so I know what to look for when things go wrong.

I was inspired to all of this by the YouTube video series by Robert Baruch[1], where he tries to recreate the 6800 CPU on a FPGA using nMigen with formal verification.

Bugs hide in the extra chars.

On a more serious note, there are several (debatable) benefits to brevity (in programming & in general communication);

- less code to keep in your head
- less chance of stupid typos (e.g. prinft instead of printf)
- more "expressive" in that each char has more meaning
- to someone who is fluent in the "shorthand", it is quicker to both write & read

As Mr Graham states, most arguments are about the differences in the meaning and definition of words.

Your meaning of "being interested in ideas" and specially "stuff" is different to Graham's.

This is not a surprise because both "idea" and "stuff" are just generic placeholders in which you can enter whatever you want.

I see that a lot when I write or speak to a big group of people. No matter what I say somebody somewhere interprets it in the worst possible way I could barely imagine myself.
