"It takes more time to learn" is an important aspect of UX, and as I've said there are clearly ways in which the git UX can be improved.

But having said that, I really feel like the experience of expert users also matters and is often overlooked in discussions of UX. And I just don't think people love software when their experience using it is terrible.
MS as the underwriter sold more than 100% of the shares, which means it was effectively shorting.

Also worth noting "naked shorts" and "naked shorting" are two different things... https://www.bloomberg.com/opinion/articles/2019-05-15/wework...
This isn't a limitation of the storage, the card has a UHS-I interface, which has a bus speed of 104MB/s. UHS-II cards exist and are somewhat faster.

The upcoming microSD Express interface standard will support a 985MB/s bus speed.

you know, this should be possible with AI and CV: train the NN with millions of words typed on a keyboard with stereo cameras (or perhaps even sonar) mounted just below the screen pointing directly at the fingers. between seeing where the fingers are landing and using some sort of auto-correct-style intelligence tied into dictionary lookups of what words could be produced, it should be possible to have a virtual keyboard.

I'm not sure what the benefit of such a thing would be, and of course typing directly on metal wouldn't be comfortable. but there may be a use somewhere.

If a lane is shut down due to an accident, it is better to have five spares though.
read about domio in the WSJ! love the focus on group travelers!
For highly congested areas the increase in the number of lanes is done to accommodate the number of cars on a given route (optimize for capacity). If you can physically fit four times as many cars on a route, but it results in only being able to move at 1/3 normal speed you are still moving more cars over time than a two lane road.
The underwriter sets the offering price based on the amount of capital the company wants to raise and the level of demand from investors.

The opening price is set by supply and demand. Few investors can buy an IPO at the offering price, because most shares go to the underwriter’s best institutional clients, and some are reserved for the company’s “friends and family.” So most investors' only option is to buy in the open market when the shares start trading.

The day an IPO is released, buy and sell orders pile up until they are balanced against each other, determining the opening price. If the demand for shares exceeds the supply, the shares open higher than the offering price; otherwise they open lower.
Today's cars are much safer than the cars of the 70s at higher speeds. Not only do they better protect the occupants in an impact but they steer better, break better and are far more stable. Add to that better fuel efficiencies and it's hard to argue that we need the same speed limits.

The truth is that American history (XIX century especially, but also before that) is horribly, appalingly racist. I cannot reconcile that fact with what you said about people in the past believing that everyone, regardless of race etc., can be made into an American.
“I don’t want to lie to people,” lieutenant Megge tells us. It may make parents feel better if the speed limit on their street is 25 mph instead of 35 mph, but that sign won’t make people drive any slower. Megge prefers speed limits that both allow people to drive at a safe speed legally, and that realistically reflect traffic speeds. People shouldn’t have a false sense of safety around roads, he says."

This is likely false.

NYC changed the speed limit to 25 mph in Nov 2014. Pedestrian deaths have been sharply reduced:

At the same time pedestrian deaths in the US as a whole have increased:

The data is clear that lower speeds means accidents are less dangerous:

What is needed is consistent enforcement. People speed because, most of the time, there are no repercussions. Speed traps feel unfair because they are so rare and arbitrary. A simple solution, blanket our roads with camera speed enforcement everywhere making it consistent and objective. Equip cars with warning lights giving people a chance to slow down before getting the ticket.
A friend of mine was getting a real estate license and talked to me about the insane ways land ownership is measured, because the curvature of the earth. I believe that was just the tip of the iceburg. I'll have to check out geodesy.

I remember an ancient mathmatician described how all of existence must be a single geometric point, I think it was Euclid, but I can't find it. This all reminds me of that.

You're right, at least in the case of highly regulated markets and when the state creates artificial monopolies (e.g. electricity).

I'll correct my original comment then:

At least private companies that compete in a relatively free market are losing their own earned money when they're inefficient, not someone else's.
from Matt Levine's article linked in another comment "In every deal, there’s an overallotment, which allows the underwriters to sell 115% of the available offering to investors, effectively opening a short position. The excess 15% can be purchased by the underwriters in the open market — covering the short position — to support the stock if it goes down. More colloquially, this is known as the “greenshoe.”

But in rare cases, bankers will use a strategy called a “naked short,” which allows underwriters to sell shares in excess of that greenshoe portion and then buy them back in the open market to provide even more firepower in the event there is significant selling pressure."
Nice list. Like someone said, the true expert knows when to break the rules, but for someone who doesn't really know anything about design but needs to put together a site, just following these simple rules is likely to make a big difference.

Also, even a lot of experts should take the first point to heart more...
"Once paired, an attacker in close physical proximity to you could use their device to masquerade as your affected security key and connect to your device at the moment you are asked to press the button on your key. After that, they could attempt to change their device to appear as a Bluetooth keyboard or mouse and potentially take actions on your device."

Why is a bluetooth device allowed to spontaneously change its type and suddenly become an authenticated keyboard and/or mouise? Could this be done to insecure BT headphones or is something specific to a security key? Is the security key actually a keyboard?
It's not random, it's poorly engineered entrance and exit ramps. In order to maintain traffic flow, cars need to be able to increase to traffic speeds on on-ramps and decrease on off-ramps. Much have the beltway system put entrance and exit ramps where they definitely don't belong. Thoroughfares for in-city traffic also don't exist, the interstate has taken that role. To compound the problem, often times entrance and exit ramps are the same piece of pavement.
"Excessive speed" is often cited as a factor in vehicle crashes, but I wonder how much of that factor can be chalked up to speeders trying to spot police instead of keeping their eyes on the road.
Success is often a matter of time. A good idea too early is the wrong idea kind of thinking.

Your article is about time zones, not leap seconds?

The US has put forth a proposal to abolish leap seconds. It is now supported by China, Australia, Japan, and South Korea. The ITU keeps punting on actually voting on it - it's now scheduled for 2023.

https://en.wikipedia.org/wiki/Leap_second

A day already drifts... every single day in fact. Why is 0.9 sec the magic threshold for maximum drift? Why can't it be 1 minute of drift, or 1 hour of drift? We are putting out problematic corrections for something a minor drift on the scale of years that should be happening on the scale of centuries or millennia in my opinion.
That’s literally moving the entire population of the planet — you’d only do that in a very unusual circumstance when most people were going to die anyway if you didn’t leave, and building domes over your cities does nothing to help.

Most people don’t even move more than, what, a hundred miles from where they’re born? Just because I fancy giving it a go doesn’t mean I expect people to go to Mars en masse even if it was free.

But they could if they needed to.
Oh, it was perhaps some cathartic snark that doesn't add much to the overall discussion, but considering that the majority of comments on articles like these tend to be made up of people glorifying such income, talking about why such income isn't enough, hoping to someday have such an income, or otherwise somehow on the hedonic treadmill that makes programmers some of the wealthiest workers that have ever existed on earth, yet always looking at the coder that got better stock options and/or explaining how capitalism is simultaneously the best socioeconomic system yet ha! of course every BigCorp doing little of value in the world has such money to waste...

Well, I think it's a measured dose of realism and maybe /every single article/ posted on HN about compensation, IPOs, exits, salary negotiations, etc should have a reminder that much of the world is doing far more important things for far less money than whatever ad-tech startup got some VC money from their fellow Stanford grads this week.

> I am not sure how someone can argue against a concept that is almost by definition positive.

People argue against the "more goods" part, on the basis that we have way more stuff than we know what to do with anyway. They're sort of right, but it's throwing baby out with the bathwater. Economic growth also encompasses doing same stuff better, and being more efficient with resource use. From what I've seen, the motivation behind criticism is usually twofold: criticizing greed, and worrying that ever-increasing use will exhaust available resources.

I wish there was more information about design in regimented and disciplined fields such as Aviation where marketing is deprioritized and utilitarianism, pragmatism and functionalism takes precedence. Cockpit design, radar screen layout, nuclear power plant control panels, etc are fascinating areas of design where lives are at stake. All the fluff in consumer design takes a back seat.
Thank you, so much, to all the people that have put so many hours into making Rust what it is today.

Rust, for me, took what was, prior to learning Rust, a vague undefined notion and really helped me see it formalized into what I can now really call a "mental model" of ownership/lifetimes. It has made my code better in every language I work in.

The ticket isn't actually one for traffic safety, even though that's what they'll call it. If it were actually unsafe you'd expect far more crashes based on how often everyone drives "over the speed limit".

The reality is that "being tough on crime" and "doing something" are political points, and the use of a ticket system generates revenue. If it were law that all funds related to minor traffic infractions had to be donated to charity (without counting for taxes) you'd see a MAJOR decrease in enforcement.
We humans almost always want our concept of "what time is it" to correspond to the relative motion of the sun in the sky. We ask "what time is sunrise?", and "when will the days start getting longer?". We like "noon" to be when the sun is highest in the sky. All those things are what UTC is designed for.
Expectation of future profits, but you say

Here's a falsehood I've seen a bunch of times: the idea that Unix timestamps need to be converted to your local timezone. Unix timestamps are the number of seconds since a specific date in a specific timezone (UTC)! If a user gives you a Unix timestamp and you know they're in the PDT timezone, you should not add or subtract 7 hours of seconds to "convert" the timestamp to UTC! It already is. Similarly, if your client receives a Unix timestamp from your server, you shouldn't modify the Unix timestamp to "convert" it to your user's local timezone. Unix timestamps are always UTC. Your platform's date handling APIs should already offer a way to display a Unix timestamp in the user's timezone or an arbitrary one, and maybe even have a class that represents a Unix timestamp paired up with a specific timezone. At no point should you be doing arithmetic on the Unix timestamp portion to convert it between timezones.
traffic calming measures in residential streets have so many benefits. bulb-outs not only slow traffic, they reduce pedestrian crossing distances. street trees slow traffic by making the street seem visually narrower to drivers without actually narrowing the street, and also create shade, improve property values, and regulate temperature.

It is a short article, so relies a lot on what someone might find intuitively plausible and goes from there.

Scientists also have interests outside of their particular field, and might offer an opinion where their field is relevant to a broader discussion.

The questions may not be answerable, but then again they may. All we can do is make an attempt and see how it goes.
I don't think that the parent means that you shouldn't be structuring your billing to be per hour/day/week of work. Rather, their point is that you shouldn't be doing math like this:

1. "I think I'm worth $75/hr"

2. "the job will take 40 hours"

3. "I'll charge $3000 for it"

but rather, like this:

1. "I think they would be willing to pay me 40k for this, and I think the project should take 40 hours"

3. "Therefore, I'll negotiate for a $1000/hr pay-hourly contract with a projected end-date of two weeks."

Yes, the use-case and domain set the constraints. Using the wrong measurement type or abstraction either increases the complexity of the exceptions necessary to make it fit the constraints or increases the inaccuracy/errors... or both.

With regards to time specifically, I recall many years ago talking with an economics professor I had that was from Zimbabwe and he mentioned the frustration that western industrial nations had when attempting to establish business in Africa. Industrial nations long ago became dependent upon a higher resolution and accuracy of time and so when they say "2PM" they expect accuracy within a minute or two. But the African work force would often show up at 3PM and when confronted by this "lateness" they would reply "3 is the friend of 2." An agrarian or pre-industrial society has no real need for accuracy to the minute, but instead can operate quite well with human observation of the position of the sun. This impedance mismatch caused no end of frustration on both sides, since neither could really fully understand the other's conception of timeliness.

Is the speed bump for other-language libraries or for other-language applications?

For speeding up other-language libraries, D has a -betterC mode, which prevents you from using the subset of the language and the libraries (standard & user-defined) that relies on GC. The remaining language is a very clean C that simply works on the other language's GC'd memory (using the other language's C interface), and can use stack allocation or any heap allocation strategy of your choice for its working set (reference counting ala C++ shared_ptr could be the obvious choice, but it is your party).

For other language applications, it is a valid option to speed up the entire application by writing it in D, as it has "all" the features of those other languages + all the convenience that is afforded by a GC + threads if you don't want a multi-process design. I quote "all" because I mean useful things like blocks/closures, generic data structures, etc. - of course, neither Rust nor D give you runtime devices like monkey-patching/meta-class hackery/prototype changes.
Thanks, that was a great article and well researched. Also discovered a few other interesting tidbits on that fellow’s site.

I have a 2010 model car and I still seem to get significantly better gas mileage around 55-65 mph than I do around 70-75, although I haven’t measured it scientifically.

Isn’t this a function of wind resistance physics that can’t be solved, just mitigated?

As driving automation increases and the threat of climate change and CO2 emissions looms larger, automated cars could drive at current speed limits without getting impatient like a human driver, improving both efficiency and safety.

A time_t shouldn't go backwards (in normal operation), but a timeval does.

> "containers do not contain"

Is sort of troll bait. They do contain. That is why everyone is using them. Sure, there will be exploits to break out of them, just like with VMs, and even CPU bugs now.

Here is a good example of someone who broke out of a container on the play-with-docker.com site using a custom kernel module [1]. This allowed a container escape but you could say this was a bug since that wasn't the intent. So, you'd patch it. So, I get the joke in that people are extremely creative and will find ways around everything.

That's less of a "falsehood", more of a complete misunderstanding of what Unix time is.
> "This is why getting slow drivers to stick to the right lane is so important to roadway safety; we generally focus on joyriders’ ability to cause accidents—and rightly so—but a car driving under the speed limit in the left (passing) lane of a highway is almost as dangerous."

i really wish people would heed this rule about slower cars staying to the right (regadless of speed). if you are not passing the car to your right, you should move to the right until you are, but many people scoot to the left lane and set their cruise control so they can zone out (and possibly occupy their brains with something else like talking to other people).

this would not only minimize speed deltas and reduce accidents, but it would also improve throughput as speedier traffic clears out faster. and drivers should never just zone out while operating a machine capable of killing people.

in any case, i both agree with the article--i actually think speed limits should be accurately set at the 85th percentile, called "suggested speed" or the like, and decriminalized--and support traffic calming measures in urban areas like narrowing lanes, adding more trees/curves, and making commercial streets mixed use by default.

I honestly fail to see what has been dishonest in the communications around this.

The plan for .NET 5 does, in fact, unify .NET Standard, Core and Xamarin. These will no longer be separate things but will go forward under one name.

I'm not sure what you're claiming as the _breaking change_. Can you be specific? It's not, in fact, going to break anything from what I can see. .NET Standard will simply continue to grow larger in .NET Core 3+ until it covers everything. This seems to me to be very different from the Python situation where you are (probably) forced to make code changes to compile with Python 3. If I have some code that compiles with .NET Standard 2.0, are you under the impression that it won't compile with .NET Core 3+ or .NET 5? If so, what leads you to think that?
The OP mentions SV but doesn't restrict its comments to it. It states "But it's the reality of the industry right now." not "..reality of the industry right now in the valley."

The only one I can think of is: determining the phase of the 24 hour day (as measured by atomic clocks) with respect to the Earth's rotation.

It does seem logical use TAI for civil time. People interested in calculating the Earth's rotation to high precision could consult a regularly-updated publication somewhere.
Eventually the Earth's rotation will drift out-of-sync with the atomic clock timebase, but that won't be important until we accumulate several minutes/hours of error from TAI which could be centuries from now.
