Again, a bit of a sweeping (and false) perception informed by our local historical and cultural context. There is strong anthropological evidence that for dozens of millennia matriarchal societies were the norm. This survived well into the pre-colonial era in Africa. It just appears that way because patriarchal structures have dominated for most of the recent past (~4000-5000 years), and because this period coincides with the historical record... again, is this a quirk or a consequence, and in the latter case, which way does causation flow?
I agree in general I agree, but sometimes speed can be of the essence. Unfortunately no country on earth was in a rush to stop the spread early on. So much could’ve been done in the early fase if a national and international response would’ve been coherent.
Japan introduced taxes to remove the incentives for speculative investments in realestate. The changes mostly seemed to have worked, but it came at a high cost for the speculators.
That might work on how a particular feature works (e.g. does the word count include symbols that have spaces either side of them?). If you're talking about the fundamentally changing the architecture and user interface of a program that takes a multi-person team to build, never mind one that the government want run by millions of people, you'd usually end up with less leeway.

We just needed something to keep track of how long it took us to do a job so I built a simple tool to keep track of time, update time, make notes, log entries, and even add teams so you can see what everyone is working on. Feel free to use it and report any bugs.

It was excited and my team were the ones who developed and designed it. I just made it work. But I don't really maintain it much anymore. My team stopped using it a while ago and while there was some discussion to build in new features... I just didn't see a need as they were using it less.

I mainly use it for my own projects when I work for clients to keep track of my time commitment. It can be used as a time invoice. So you hit the start button and it logs your time in and you leave yourself a note.

It might be outdated and not work on some browsers, but it still works for me on Google Chrome. A few of my friends sometimes use it to to keep track of time. But when I was developing it, I never build anything specifically branded to something, so I created it as a generic time tracker, and anyone can use it.

What actually happens to the money that gets put into the stock market? I mean, I understand that there are people holding stocks and then people offer to buy/sell them at a given price; but, how does the company plan to benefit if the stock just keeps moving back and forth multiple third parties? Doesn't a company go public to raise money? If so, how does the company benefit from the daily changes in the stock and when someone buys stock in the company? Does the company have a fixed number of stock that they trade as well on the market?
China has no free press and is not really transparant with their numbers, so we can't use them as an example.

Qubit is physical random generator, which quickly oscillates between 0 and 1. It does that so quickly, so scientists must operate with probabilities to perform calculations. They create analog quantum computers, where right solutions are much more probable than wrong ones, then let system to figure them out, then sample solutions periodically.
Am I too charitable or is it possible that this guy is actually just joking and entertaining themselves? I can't imagine someone being serious with these threats and at the same time typing out shoot shoot shoot. Maybe it is just a weird hobby.

Maybe this person pours themselves a cup of coffee every morning and goes to Wikipedia to do his morning revert.
That's a good point. For some reason we don't adjust the pronunciation on that one, but we do on other words like "contract": 'contract (noun), con'tract (verb).

The word "research" is an odd one as it's pronounced as re'search as both verb and noun in BrE but 'research as both verb and noun in AmE.

But, of course, many British speakers now use the American way without realising (as evidenced by replies to my original comment).

> startups that merely survive won’t be judged merely against their peers that also survived; they will also compete with brand-new startups for capital and companies that didn’t need to hunker down during lean times.

This is so totally against history as to be laughable.

Sure, some very small single digit percentage of good VCs will be making hay and throwing money at companies.

Most VC's are sheep. With nobody to follow, the majority of VC's will simply hold onto their money. After an implosion, there will be zero new companies competing against you for at least 6-12 months.

Even better, some ideas that couldn't get their heads above water when there was too much chum can finally breathe and take off.

A lot of the most successful tech companies got that way because they exited the other side of an implosion.

This opinion could easily spark one of these wars, but I really wish a global community like Wikipedia wouldn't use ablest language in a title of a post like this...

In the last few years, I saw a lot of people using monorepos, and discouraging using submodules.

Frankly, I don't know why. For small projects, sure - it it an overhead. For anything larger, I find it useful to encapsulate things - be it installable packages, or if it is not the case - at least other repositories.

In the last months I split one project into 4 repos (https://github.com/Quantum-Game/) and couldn't be happier about that move. It makes the code cleaner, Pull Requests more separated, etc.
> Which we cannot measure with complete accuracy

I very much dislike this phrasing, because it suggests that it is just us that are not capable of building an apparatus to enable us to do so.

Imagine a gear transmission or a lever: You can transform distance into force and vice versa. It is up to your choosing if you want to go with more speed or more force by changing the point along the lever, where your transmission happens. It is not possible to build a transmission, which gives you the most distance and the most force simultaneously. In this system of transmission, one is the other, just a different perspective.

And it is the same with the location and impulse of a quantum. You can choose to have more information in the shape of location or more in the shape of impulse by changing your measurement (like the point along the lever). But you can't have both, because there is only a constant amount of information which is represented in a combination of location and impulse.

Actually, the uncertainty part of heisenberg uncertainty principle is a purely mathematical limitation (called Gabor limit) and only the Planck constant makes it physical.

Gabor limit:
a • b >= 1/(4•PI)

Heisenberg's uncertainty principle:
a • b >= h/(4•PI)

So the Planck constant is kind of the maximal sampling resolution of the fields / signals in our universe.
Not the entire world consists of ‘did you just assume my gender’ people. Most people don’t care at all.

Stereotypes exist because they model people pretty well.

If you enter that your gender is unicorn you probably just get slightly more generic ads.

Here’s a scary thought: if you walk the street everyone who sees you will assume your gender.
Ask HN: Best Ressource (Book) for a New Linux Server Administrator
Dear HN, in the near future I'm going to help a new person find their way into Linux server administration.

Their idea, which I think is very good, is to start by setting up their own small VPS to get a first feeling for all of this. Now they asked whether I knew a good resource (e.g. a book) which leads you trough the first steps (i.e. setting up SSH securely, etc.).

Well, aside from some good online tutorials, I wasn't able to really recommend something in good conscience. Do you know of any good and current "Introduction to Linux Server Administration" resources worth recommending?

TL;DR: Which book would you recommend an absolute beginner wanting to set-up their first small Linux server?
I pursued data science, It's a good blend of tech and domain knowledge.

The domain is what interests me, and the technical part is what makes it enjoyable. The amount of programming is probably one tenth (if even that) of what a regular software engineer would write, but there's always room for new ideas. Lately I've found myself writing more and more code for automation and other auxiliary stuff.

In the end you want to apply technical and scientific methods to the data, guided by your domain expertise, and deliver results to someone.

For some, it's nothing more than cleaning excel spreadsheets and generating reports, for others it's building and using state of the art machine learning methods on extremely large data sets - so not all data science jobs are alike from a technical standpoint.

It depends how you say it. For me the default in British is still an intensifier, but you can signal that you're using the American way using context, tone, facial expression etc.

The more important thing, I think, is that Americans don't understand the first sense at all. You have to say "pretty good" or something to have the same effect.

IBM's Quantum Experience is great for this. It walks you through the quantum gates you can use and lets you write small programs for quantum processors.

Thanks for allaying some of the privacy concerns around the place Mike.....

But to be honest, I will wait for the Apple/Google contact tracing app to be released (because it will be soooo open and better and with a generic name can be used beyond the current pandemic).

It will not only tell me I've just sat next to someone with Covid19 on my train ride to work, but that they also updated their status to single this morning with a broken heart emoji. They've also been up all night watching relationship expert advice videos and about to start their 10 hour shift (since they socialize online under different pseudonyms, their employer is none the wiser) as an open heart surgeon... And if i’m inclined and would like to take up a limited special offer, I can get a 50% rebate on my 21yo gold plated private health fund if I can convince the Covid19 case to co-isolate immediately in the seat in front of me with the other Covid19 case. A full rebate if I can convince both of them to get off at the next station!!
To be fair though, a part of ADHD can manifest itself this way. From what I've read it's a pretty common complaint that people with ADHD have trouble doing things they're not interested in. In a lot of those cases you also hear about how their interests change all the time.
>Speaking as a rainbow myself over here, it's...not unlikely? Throw a bunch of teenagers or young adults in support groups together with the subtext that they all have the same sexual orientation with no chance of being shamed for making advances for what's effectively the first time in most of their lives, and it doesn't take a fortune teller to figure out what's probably going to be happening in greater rates for those kids.

Also rainbow, but I don't quite see that. The straight kids are already thrown together in all kinds of ways and for the most part know that each other are straight. On top of that, there's the issue of numbers. If there are, say, 20 out gay kids of a given gender in a high school, it's quite likely that there are no mutual attractions between any of them.
Dams are very efficient to construct, because you take advantage of natural valleys - erosion has done most of the heavy construction work for you. The catchment area isn't just the surface area of the reservoir, but huge areas of surrounding land. Major hydroelectric reservoirs are unimaginably vast.

Ask HN: Negotiating remote start at big N company in times of Covid-19
I'm entering the workforce for the first time as a graduate, and am about to enter negotiations with one of the big tech companies. One of my goals for this negotiation is to agree that I will stay where I am for ~6 months and work remotely, and only relocate after it is clear that travel restrictions have disappeared for good. Specific questions:

* Is my goal of 6 months feasible or totally unrealistic?

* If you start working remotely, can the company force relocation in the future? Does this date have to be written into the contract or would there be an "advanced notice period"?

Context: I am located in Europe. The office is a few hours away from where I currently live, but across a country border. Starting remotely will have to happen at the moment because of travel restrictions, and this would require to have a contract of employment in my home country at the start. I do not want to relocate until travel restrictions are permanently lifted as I do not want to be cut off from my family here.
My love/hate thing with hackathons is how it gives non-coders the idea that you can put together a product in a weekend.

There's a vast difference between hackathon code designed to maybe last for an hour during a demo (with no security or privacy concerns) and production code that can actually support a business model. And it's not just "so... that'll take twice as long to make?". Turning a weekend hackathon demo into an actual production code base can take weeks or months.

But explaining that to a non-coder is really difficult. Hackathons set expectations so high.
Is Jeremy Clarkson "very posh"? Just one example off the top of my head of someone who would use "quite good" in the British way.

I think there is possibly a big difference between spoken and written language here. Would you really use "quite good" in that sense while speaking? I don't think so. I think British people would "meh, it's OK".
> Fermi questions[0] (oft maligned when asked in interviews)

I really don’t get when people bemoan these. Do they not get that it’s supposed to be an estimation, and it’s not actually a quiz of whether you’ve memorized a seemingly useless bit of trivia? Do they not see how it can be a useful skill to have, especially in an engineering field where you frequently deal with many orders of magnitude? (If acquiring this lock takes 100 ns, am I doing this often enough for this to cause a user-perceivable delay longer than doing it single-threaded?)
Those aren't the definitions I use. I'd argue a terrorist is someone whose goal and/or means to achieve a goal is terror. Even further off topic, but I really think we should dial down on usage of terrorist. A "terrorist" is first and foremost a criminal, the rest is sensationalization and fear mongering.
Was about to write something like this myself, thanks for sharing!
A very funny thing about fuzzing is how random input testing used to be so looked down upon by the software testing community. Read old (1970s) testing books and you'll see comments like "random testing is the worst kind of testing". I still saw this even as recently as a decade ago.
> It's the idea that living freely is a sacred value; that we won't and shouldn't take the path of the fewest deaths, if that path leads to a society we don't want to live in.

And you can see in Italy how the (hoped) path for the fewest deaths as opposed to (rather than along with) freedom led to a horrible result. The current PM has basically trampled on every constitutional right with authority that he should not have, and the effects of the policy (besides locking up people for at least 75 days) aren't that great. And let's not talk about the social / economical aspect.

The authoritarian aspect of these moves was clearly shown when he threatened closing things again if infections rise (as if it's the fault of the people he's supposed to protect).

That's a general problem of coding, that the next edit can violate an invariant. The advantage with Rust is that, for several types of invariants, you only need to check places with an unsafe block during code review or audits. Everywhere else, the compiler upholds these invariants for you.
Putting Switzerland and Sweden in the same bucket here isn't fair, IMO. In Switzerland, most things were closed down like in our neighbor countries (some things are reopening now, but still very limited). A difference was that while other countries said no groups of >2 people, in Switzerland the rule was no groups of >5 people, so in that sense it was more lax, but it's far more strict than Sweden's policy.

I didn't see good explanation of Einstein's twin paradox. Have you seen one? I have seen only clear explanation based on fact that observer will feel acceleration when he will come back and this is what breaks symmetry, but it appears that explanation based on acceleration are wrong, because it seems that acceleration is not necessary to explain this paradox.
