It's possible to have different gauges at the same station, requiring just a change of train rather than an additional bus transfer. And some systems are variable gauge, allowing for the same train to operate on different systems.

I wonder why ex-faang company needs to be mentioned as a description of the founder.
They replaced an iPhone 6 bought abroad (on their store) by a new one in an Apple Store when it had a problem (which didn’t even warrant remplacement and I think the problem was actually fixed but the staff nor I recognize it at that tule). Whole operating took less than half an hour. Honestly that’s what I call stellar service.
> In many contexts, having identity tied to your online profile should make people act more like humans

That's the point, isn't it? A person can be good or bad, but when you group people together via social media, you find out just how many of them are just terrible human beings. People acting like humans is exactly what you don't want to happen.

Now of course, if you systematically do that, the version of reality that trolls are broadcasting wins. Because no other then trolls voice is to be heard.

And that what happening on the internet for years, where people who were harassed and trolled were expected to shut up and leave the place. And recently, I am equally thankful to historians who do engage with what trolls are saying. Because "smart" people just used to let trolls version of it to stand.

That rule made people who followed it fail and loose. So, people are not following it anymore.

> .NET remains a poor framework to do systems programming in

Have you clicked that link? Essentially, I’ve re-implemented parts of ffmpeg’s libavformat and libavcodec in C#. On Raspberry Pi, the software uses 15% of CPU time while playing 12 mbit/sec 1080p video, on par with VLC, while using 20% less RAM than VLC. If that’s not a system programming, then what is?

BTW, I don’t think I allocate any objects on heap while playing the video, therefore no GC is involved, and no degree of unpredictability is introduced. Wasn’t hard at all, just recycling buffers between frames.
FWIW I moved to Tokyo in part because it’s not a hellscape, but a great place to live if you like cities (and have income). I guess if you only consider American cities then maybe you might conflate cities with hellscapes.

Most normal people would take that as a sign that the founder has already had a sucessful career in tech, because "FAANG" don't hire mediocre workers. The journalists knowing this trend, use this information to communicate this to people, speaking in their language. (Also this language makes some sense as well.) I don't see a problem.

I lived here before and after the official name change. Everyone I know still calls it "Czech Republic" - "Czechia" feels weird and unnatural to me.

Additionally it sounds quite close to "Čechy" - what in English we call "Bohemia" - which refers only to the western half of the country (see [1]). So it reminds me a little bit of when people call the UK "England" - so as a Scot living in Moravia I sympathise a little with some locals who feel a bit irked by it :-)

Ask HN: Best book (or resource) for learning Windows 10
I recently stumbled across some odd results from a sysinternals tool that let me know I don't know Windows 10 as well as I thought I did. I'm looking for tips as to the best books, or other resources, for learning the inner workings of this operating system and I would like it to cover as much as possible. Ideally, it starts at the boot process and works forward from there.

Additionally, any recommendations on books that contain other commonly used OS are welcome. I'm not willing to spend as much money on them but they would be a handy reference when I do come across different systems.

Democracy needs a free press, and not just free but one that is motivated by high quality fact based news. The high quality part is subjective but maybe achievable via a peer review group like a Journalist Guild type awards system. Publications would be required to need to maintain a certain standard of conduct to access the funds awarded by guild. Free of advertising to avoid click bait "news".

Perhaps such a model could co-exist with a commercial element. Access to premium services, to keep my proposal vague and aspirational.
Musicians.

There is a distinction in the market between professionals and hobbyists, but then most of the MI market is borne on the fact that there are about 2 - 10 million new musician students coming into the scene every year - a portion will become hobbyists, and a very, very small percentage will become 'professionals', by many variant degrees of definition of the word professional - i.e. gets paid, has money to spend on music stuff.

Musicians can be pro or hobbyist, doesn't matter to the instrument maker unless its important the end user feels special. Thus, the higher prices for 'special' instruments.

Music, though, doesn't need to be high quality in order to be experienced. Even low quality instruments can sound amazing in the hands of a musician - hobbyist or otherwise.

Back in the day choosing your rail gauge had a large input from the military, since it was strategically disadvantageous to have the enemy supply lines easily extended into your heartland. This was before the days of air forces or even proper highway systems, so logistics depended largely on horse drawn wagon trains.

It's not so different from the Soviets choosing an ever so slightly different caliber for their mortars so it's not compatible with the ones from NATO.

It's continual exploration with an expert on hand to help when they get stuck or see some basic skills training.

I'm not impressed. It is not a "grand engineering breakthrough" by any stretch of imagination.
So weird -- when did we all decide to start saying "I was laying in bed" instead of "I was lying in bed"? I have noticed this shift over the past few years.

Laying has always been past tense "That day I lay in bed for hours" or transitive "I lay the books down". Chickens also could be laying in bed, if eggs are coming out of them. Lying has always been intransitive "I was lying in bed". But nowadays, "I was laying in bed" is almost all I see.

Won't this forwarding/proxying make the internal services not see the actual source IP addresses making access logs less useful? (Sure, if you're proxying HTTP there's X-Forwarded-For but that's more configuration to get right and there are other protocols.) It sounds like you would be better served by a firewall, ideally both on the server node and in front of it.

Musical Instrument markup is still pretty astonishing outside the 'cocktail set' shenanigans, especially if your eyes have been bleeding from the situation in the tech scene.

It doesn't have to be a 'classic' synthesiser to command extraordinary markup/profit.

There is a reason why the current synthesiser market is vibrant and active and virulent - and nobody is playing well with each other, there are more competing platforms to do the same thing than many other spaces.

That reason is, you can spend $100 on a BOM-per-product, and sell it for 5 figures, year after year. That $3000 synth workstation, at scale, can add up to a lot of real, good old fashioned atom-based commercialisation.

Oh, I don't have either, I was just using that as the canonical example.
The main thing I see missing in these comments is the approach from the other end. There will be a tipping point where appliance makers design small features to make their products “robot friendly.” Like making openings larger, buttons larger and otherwise easier for cheaper robots to interact with. And it will create a feedback loop where robots get more popular because they can do more in a robot enabled home, and because they are more popular they get better, and because they are better they get more popular.

Let’s be honest, the roomba sucks, so It’s not really a counter argument.

Once there is a robot that is useful and also seen as a status symbol, that’s when the feedback loop will begin.

Trump does it precisely for that reason. You can see his trolling spiking when he has to divert attention from bad news. Most of his activity is basically 50/50 between "energize base by creating outrage that feeds into victim narrative" and "define what news media will talk about next".

It's not particularly original, Berlusconi did it too (albeit with more traditional means).
Seems like something an A/B testing tool could be modified to do, if you could get the data from LinkedIn via an API or something and show a certain 'variation' based on which the user matches a certain category/number of categories.

However, it seems like something that'd take an awful lot of work, and the amount needed would basically grow exponentially depending on how fine grained you wanted the targeting to be. That probably wouldn't give you a great return on investment, especially given that even a perfectly targeted website is nowhere near sufficient enough to guarantee a sale/make it that much more likely.

Effective code reviews in 5 easy steps
I've been teaching in person and had to transition online during COVID-19.

I agree with all of his points that going online can degrade the experience.

but all of this pre-supposes what it means to teach and what it means to learn.

Some comments mention children, but the OP is a Yale law professor. Seems like esp. higher ed needs to be a little more open minded in their thinking going forward given the circumstances.

> it’s important to acknowledge what online learning misses.

It seems to me that by only describing how a zoom meeting is lacking vs. an in person classroom he's missing what an online learning environment is capable of creating.

A lot of his arguments seem to be centered around grabbing and holding someone's attention in a digital environment, which I also empathize with, but I think some things can also be a symptom of an educational system whose purpose is not always actual learning- i.e., is the purpose of grade school educational, or is it day care for working parents? Is the purpose of yale law school learning about law or is it to serve as a gate keeper in the legal profession? etc.

When the whole reason people are sitting there has not much to do with what you're trying to convey, it's no wonder they have trouble paying attention.

That being said, if students are interested and expectations are aligned, some things that I found that some things were actually improved upon in a digital setting: (specifically I teach at a coding bootcamp)

- one-on-one teaching can feel more intimate and effective, (as in a zoom breakout room) since you are not speaking to that student in the classroom where others can overhear or that you don't also have to speak to the whole class at the same time. Sharing someone's screen feels more like you are right there with them.

- the asynchronous nature of doing things online means that people can come more well prepared vs. having to have everyone in sync in a classroom all the times, in real time.

- it's logistically simpler to not ask 30 ( 50? 100?) people to all gather in the same physical location at the same time. I suppose this is obvious, but when you stop to consider this, physically transporting yourself somewhere else is, at best, tangentially related to learning something.

- also obviously, it's easier to convey certain things on a screen than it is in person speaking / on a white-board. Specifically I mean being able to focus in on a diagram or example. On a projector or on a white board you simply become limited by real estate that you get back on a whole screen.

I understand the comparison and think the us is having a hard time fighting the virus with its mostly unhealthy population. But I agree a bit with (my understanding of) the parent.

The US could make a lot of laws to reduce the number of deaths from all diseases. Tax fast food, make it illegal, whatever. But we decide against that. I feel like people saying "this can save people and doesn't cost that much" are not taking into account that a lot of things can be done and potentially save people, but we have decided as a society not to do them.

Also comparing WW2 deaths vs covid death is a terrible comparison. Most deaths during WW2 (in the us) mustve been from healthy, young men vs covis where it's mostly the old and already sick.
