I'm working on tennis app that started with reservation module, than we introduced tennis rang for players (similiar to chess elo), than we used tournament module for ouself that is now feature as well, and we are working on new features for tennis coaches.
My question is, do I need to be more focused on few features, or try new features and see what works and what doesn't?

What's your experience?
Conductive metals have resistance, so they must lose a portion of their energy as heat. A pipeline only has to overcome friction on the inner surface of the pipe, which is easily reduced by having a wider pipe. So this isn't a surprise.

Hydrogen pipes will have the same benefits, albeit you will want a wider pipe due to the lower density.
Black Friday Offer: 75% Off on Udacity Nanodegrees
I can think of some other reasons why employers value degrees:

1- conventional mindedness, funnily enough. Everyone else has been doing it that way so I should.

2- protecting career risk in case the new hire sucks. You can point to their qualifications and say that anyone would've made that decision

3- "I have a degree, I'm good, and I subconsciously want to hire people that ticked the same boxes as me"
Outside of peak times, that might be a reality sooner than expected.

Wind doesn't stop blowing and it might be argued that it is stronger at night.

Solar peak does not match the consumption peak neither.
More like 300% as electricity -> hydrogen -> electricity is around 35% efficient IIRC
Article says it's only killed a million people damn man we allow tobacco to be sold every day I even own a tobacco farm let me tell you it kills a lot more than this coronavirus. Yet if I keep lobbying they'll let me keep selling this poison to the masses laughing my ass off. Part of the lobbying that I do is to ensure that every single tobacco death is counted correctly so many slips on a pack of cigarettes and dies and they market tobacco as the death it's my job to make sure that that is corrected. Imagine all of the covid deaths they're marking just because shortage of supply. There's no me to lobby for covid ensuring every death marked by the virus is actually by the virus. I keep seeing stories where a person dies from something completely unrelated to virus yet the doctors blamed covid.

I that includes a very narrow form of polygamy. In particular, that men are the only ones allowed to take multiple partners. In a form of polygamy where everyone gets to take multiple partners it is exactly the opposite. Everyone is always available to form bonds with whom they want. This notion of being "taken" in marriage is what breaks polygamy.

Because of non-functional properties of programming code. Of course the archetype of a Collector can be used as a backing data structure. But maybe, if you want an accumulator you're better of calculating the sum without constructing a list (or relying on fusion).
The last 40 years have seen information asymmetry decline like in no other era. Until now, that mostly benefited the rich. Workers are just catching up on the same phenomenon that led to the new Gilded Age.

I hope we can avoid massacres this time.

They address why they are targeting Amazon a bit further down. They view Amazon as one of the most extreme examples of problems many companies have, and Amazon has done exceptionally well compared to other companies during the pandemic.
A draft. OpenSSL devs wait for it to be finished.
That $1B into Blue Origin is also paying other people. I also think very few people in the US would be able to make life changing decisions with $1,500, but that’s conjecture and neither here nor there.

The point is the solution is legislation affecting all businesses. It’s a waste of resources to focus on individual businesses.

Also, I’m not sure which market Amazon has captured. A quick search shows share of online retail revenue at 25% to 35%, and only 6% of all retail. If Amazon ceased operations today, it would be trivial to switch to Walmart/Target/Bestbuy/Costco/Alibaba/eBay/Home Depot/Lowes. Shipping times might suffer for a little bit while the logistics get reallocated, but there’s no moat around Amazon’s retail website or warehouses.

This is probably an unpopular opinion but I think that Windows has the correct filesystem behaviour here for the end user. Case preserving but case insensitive.

Because realistically would normal people (not programmers) really want to have "Resume.txt" "resume.txt" and "RESUME.txt" all on their system rather than just one of them?

Though I suppose in these more modern non command line times it doesn't matter as much as it did before.

Coronavirus vaccines: Will any countries get left out?
This existed for typefaces back to the hot metal days, because like PDO the names were legally protected but the styles were not; e.g. Palatino (Stempel/Linotype) = Book Antiqua (Monotype) = Palladio (URW) = Zapf Calligraphic (Bitstream) = TeX Gyre Pagella.
Lets be even more abstract. What matters is useful work per second.

That metric is a function of clock speed, core count, lithography process, but also how many cycles each instruction takes to execute (e.g. how many cycles for an add), the instruction level parallelism in each core, branch prediction, memory architecture and caching, instruction set architecture (ISA) and its implementation, available cooling and more.

For example, by optimizing the number of cycles per instruction, increasing instruction level parallelism and branch prediction you can get a significant boost in performance, as witnessed by the massive jump[1] from the 486DX2 66Mhz to the Pentium 60 (also at 66Mhz in the video below).

Makes sense. The champagne bar being vegan has been a demand for quite some time.
It's always fun trying to explain to non-tech management the two truths of managing software development:

1. There is no objective measure of productivity that can be applied to software development.

2. Accurate estimation of development times is impossible (not difficult, actually theoretically impossible). All estimates of development times are wrong, some by more than an order of magnitude.

The second one is especially hard to grok for non-techies. I have to explain that if you insist on accurate estimates, you will get grossly padded estimates [0]. And the work will expand to fit the time available (sometimes resulting in the task exceeding even the massively padded estimates because the work expanded with the estimate). I've had many entertaining conversations attempting to explain this.

[0] Because every developer knows that an estimate will magically become a deadline.
I don't think any government has reducing demand on its radar. They all promise a green future without consumers having to change their behaviour one iota.
Reading the ridiculous lyrics and am just relieved that we don't have anything as obviously insane as this nowadays, especially with modern team building inventions like getting managers to express themselves by drawing with crayons and crafts, confess and acknowledge their faults and privileges, and participate in group mindfulness and empathy theraputic exercises.

This is of course bizarre, except...singing will make you a better salesman. I say salesman because the effect of the vocal exercise on a man's voice has a natural effect on the people around him. You will never see as much command and charisma as a choirmaster or an old stage actor.

That's the point though, it's not just someone doing it that has triggered their defences, it's many - most probably unwittlingly because of malware or even some of those cheap shitty games that mysteriously steal your battery and/or data allocation with unknown background processes.

The point is thus: they are receiving enough bad traffic from that range to have determined they need to filter it somehow.

That viewpoint is comically out of date. It's unaware of 10,000 psi carbon fiber tanks for one thing. There are many other things wrong with it.
That would be because they're trying to leverage browser fingerprinting, and you're screwing with the fingerprint.

The sad thing is, if you're privacy conscious and don't play ball with the rest of the world, and actively mitigate these surveillance/data leaking mechanisms, you're assumed to be a malicious actor by corporate risk departments the world over.

Yep. 7:15, exactly that. Plastic sheet and 20 seconds.
I can't find a reference now, but there's an old story about an early import of some software from the UK into Ireland (in the 50s or so). The software came on punched cards, and when it arrived turned out not to load. After much investigation it turned out that some cards were missing, so the vendor sent it again. This time different cards were missing. Eventually the problem was tracked down; at the time, it was normal for customs officials to retain a small sample of any bulk material imported for post-hoc inspection. The punched cards were viewed as a bulk material...
Ionic and Developer Tooling (Transcript)
Hydrogen has problems of leaking out, and damaging materials, in both cases because very small molecules can easily insert themselves where they don't belong.
I agree, it is one of the great joys of parenting :)
I think it helps a lot with imagination, curiosity, and "fastidiousness about truth" since they need to keep evaluating whether what you tell them is true.

A deeper variant of this that I do is focus more on giving them incorrect justifications for things. This helps with evaluating the reasons given for why something is true rather than the idea itself.
Lets say that your drive to be liked by your manager makes you express X more support for his ideas, or express X less arguments against them. Then the person with a more supportive base line will still appear more supportive even after this motivation adjustment.

You can work around this by just being better than your peers at manipulating feelings, but it is still a handicap.

I think the ASIC design industry is only going to start getting serious when Moore’s law finally slows down enough that we can get some breathing room. Current HW design is more akin to shipping an Electron-based CRUD, than some finely hand-crafted assembly.

That's just plain false.

Any significant amount of Hydrogen gas is crazy dangerous to work with because it has such a wide explosive range.

Reading through the Saturn V manual (as you do), the design aspect that surprised me the most was just how much of the hardware was dedicated to hydrogen gas leak detection! It was everywhere. Even the skin of the thing was a two layer affair in places, deliberately designed with channels and helium pressurisation in a complicated way to flush even the tiniest leak through long channels to the nearest sensor.

It sounds crazy until you realise that even a pinhole leak would release gas that rises up and concentrates in spaces between bulkheads and tanks where it can rapidly reach an explosive mixture ratio.

Hydrogen is not safe at all.

Ask HN: How to Learn the Art of Storytelling?
I tend to view and present myself (and other events I've witnessed) in a very straight forward and uninteresting manner. So much so as to not do justice to the experience and learnings. My main fear is to make everyone (myself included) cringe. How do I overcome this and learn to tell or write stories that people want to hear?
How to Think for Yourself

"Read this article" :D
Why have any protections then? Let the invisible hand of the market rule everything.
Okay, but how do you have a lively discussion but also have nobody’s ideas getting shouted down? Would a lively discussion involve everyone agreeing with one another?

Edit: people are apparently not getting my central point here: it might be that, if you’re a conformist, you see a whole bunch of people nodding and saying roughly the same things and think, “this is a lively discussion!” But then see people disagreeing with you and think, “what happened to this once lively community?”

But, it could also be that we’re talking about something else. But the parent post is too vague for me to tell. I sense a more concrete suggestion coming on? Maybe related to the power of downvotes to silence dissent?
Companies need to stop treating IPs or groups of IPs like identifiers. When I'm in my office, I can't access yelp. They blocked that ip range for some reason, maybe because of something we did. We block entire countries at work because we were getting a lot of DDOS from those countries and we don't do business their but it ends up blocking a lot of legit use cases and wasting a lot of time.
This is so great! Many years ago I wrote an article for Digital Web Magazine called "Color Theory for the Color Blind", which up until today, I was mostly proud of. This blows that out of the water.

The goals were the same: How can we logically and programmatically understand color without relying on intuition, taste, and color sightedness?

I don't think either of us managed to solve the part about taste. Neither article has a particularly inspired use of color within it. However, I think this approach allows a color-blind programmer to work derivatively from a designer's initial concept and be confident that we're not butchering the product.

I always find this problem very hard to parse.

You're right that it's an arbitrary change, but on the other hand, every change is arbitrary whem you want to modify an established system.

Of course the question here is if this is the morally correct way of doing things.

Personally, this all sounds weird to me: it's like enforcing a rule where, from now on, at least 25% of your workforce must be muslim. Why should one's religion be of any concern in all this?

Same thing for gender.

If the problem is that the positions are being filled in a shady or non-meritocratic way, that's the problem to address. But I'm not sure this is what it's been talked about here.
Not really, it definitely assumes some background with Haskell, but it's far from 'veteran' level. All of the code samples except for the very last section only use elementary concepts.

Why do older people heal more slowly?
I can see Hydrogen as having uses for industrial chemistry. I can also see it having uses for jet fuel, and for vehicles that must travel a long way away from charging points, assuming batteries never reach the same energy density as gasoline.

But for civilian cars, it's a bad battery. It's hard to store and hard to use, and it explodes. The only reason fuel companies love it is that it keeps people coming to the pumps, rather than plugging in any damn place like with battery-electric.

It's an upside down logic to think that low status men cause war. Yes, they do have more incentives to go to war, there is a correlation, but this doesn't mean it's the cause. I'd bet that in every such situation the root cause of war is the hunger of power of the top leadership. They could deliberately impose even worse imbalance and use the "hate force" of low status men as a destructive energy in a war. This is what Russia does nowadays, I believe.
I see a lot of similar stuff on Youtube these days.

A recent Economics Explained walked through wealth inequality in some Scandinavian countries (TL;DR: it's high). This is different from income inequality, which is quite low. It walked through the wealth of Charlene de Carvalho-Heineken, who has a net worth of $13B, by virtue of having inherited Heineken. Her family bought (not founded) Heineken 200 years ago, and the family fortune dates back a half-millennium.

There are really neat documentary channels like that. I'm not downplaying Burke, who was brilliant, but two bits of progress:

- In 1978, he didn't have the Internet. Research is much easier today.

- In 2020, anyone can produce high-quality documentaries. In 1978, you needed a massive investment.

I'm not trying to imply it's easy, but we've gone from where you need a video editing studies, reels of film, and a research team, to where you just need to spend a few years as a super-nerd to pick up the requisite skills, and drop perhaps $2000 on cameras and microphones. Indeed, if you're scrappy, you can do pro-quality with just a better cell phone and computer, with a lot more work.

I'd guess a lot of channels were inspired by Connections.

I know Mechanical Universe inspired a lot of (now better) Youtube channels, like 3Blue1Brown. So these early documentaries were pivotal, but we've also come a long ways from there.
In many ways this is just an extension of his 4 quadrants of conformism essay, so I'll argue with it using ideas from that essay. I would argue that people vastly over estimate their degree of independent mindedness because although it's easy to be independent minded in one field, especially if it's one you have been studying for a while, it's incredibly easy to fall victim to common sheep-like mentalities about any other topic you're not an expert in. Just ask non-economists what they think of the economy, all of their answers, if not outright incorrect, will be canned answers stolen directly from whatever media outlet they use.

This is important to note because literally everyone does it. I don't actually know of a single person that has not done this, and I personally have done it so many times I question my degree of independence and free will all the time. So what can we say about this? Is no one independent minded then?
That fact provides a crucial context. It's easy to come away with the narrative that Prohibition failed so people just gave up. It also coincides with women achieving a lot more political and power, which gave them more options for getting away from abusive alcoholics. That played at least some part in the end of the drive to eliminate alcohol.
This is close to becoming a FUD argument. Hydrogen does not leak out of properly designed pipes and containers in appreciable quantities. Embrittlement doesn't not happen either except for specific cases or where an incorrect alloy was used. These are mostly solved problems in modern times.
Oh I absolutely agree. I'm not defending it, just pointing out that it's not totally insane. Here in the UK I've never seen anything that nuts however.
PG just wrote down what he thinks about these things, sharing thoughts isn't a waste of time.
Facebook is actually doing much better in this regard than Google/Amazon/etc..

For example, in certain developing countries "social media" is included for free with your phone plan, often there is no net neutrality and competition between carriers has forced all of them to offer this. As a result, local businesses are forced to have Facebook and Instagram pages, because their audience cannot visit a regular website on most days. Which ensures most people need the "real" internet less and less, and are less likely to pay for it, locking them into Facebook/Instagram/Whatsapp for a lot of their communication.
Culturally specific knowledge obviously correlates with an ability to learn by the very definition of the ability to learn.

I doubt this viewpoint is out of fashion. The problem is that it is hard to compare people from different environments if you use knowledge that depends on the environment...
They probably let the builders name it. If you have ever worked on a building site you will have found that every noun is preceeded by the word fucking.

Jewsons, a builders merchant in the UK did a brilliant take on this in one of their adverts.

If your goal is to learn how to tell a story to a live audience see this: https://www.youtube.com/watch?v=Unzc731iCUY

Otherwise I'd suggest you read up a lot of literature, start with classic folk tales like those collected by the brothers Grimm. The more you read the easier it will become to write a proper story. Lastly as you're reading I'd suggest you start writing material yourself and maybe publishing it online on some web novel sites. At first people will be very critical of what you have written, but with time it should change for the better. Lastly, writing is a habit, just like coding. A habit should be repeated daily to become stronger. Read and write each day, unless you're feeling foggy or in need of rest. After a certain amount of time it should just click, but realize that that amount of time varies from person to person, some may never break that threshold, others are talented and are able to break through just like that. Best of luck!
