Unfortunately, very few homes in the UK have any air ducting. I'm looking at installing a MHRV system at the moment, but planning the ducts is a nightmare. Brick walls, lintels and structural joists everywhere with no headroom between floor and ceiling.

We absolutely should be doing it in new builds though, and we're not.
> that could possibly be applied to social media companies as well.

No, it can’t because social media isn’t based on phone numbers, and social networks aren’t telephone networks, and each one works differently.

I don't think it's strange at all; dividing the world's people into two geographical groups doesn't imply the groups have no contact or interchange! It's well established historically, for example, that Egypt and Mesopotamia developed geometry long before the Greeks, and Pythagoras is said (by nominally historical accounts, intended to be more literaly factual than the Gnostic parables you're speaking of) to have studied in both places. Both Egypt and Mesopotamia were also part of the "East" for the Greeks until Hellenistic times, even though Cairo is geographically further west than Cyprus; maybe Cyprus was also "East"?

Also, to the Chinese, India was "the West". The famous novel Journey to the West is a fictionalized account of the Buddhist monk Xuanzang who traveled from China to India to bring back copies of Buddhist texts that had not yet reached China. And nobody doubts that Buddhism originally reached China from India ("the West").

I don't think "political order differences" makes sense as a distinguishing mark. Over the last 2500 years there's been theocracy, hereditary monarchy, various kinds of democracy, military dictatorship, etc., in both the East and the West, however you define them.
Yep, "early adopter pricing"... except it will probably go down in price with mass production. It does look cool though!

Tesla doesn’t know how to do change management.
It's an outstanding book about an outstanding man but still a bit of a hagiography when it comes to all the "fighter mafia's" ideas on aircraft design. However, his focus on prioritizing investments in people over weapons is a truly underappreciated part of his legacy.

Another story of an undersung military airpower leader is that of Red Flag & Moody Suter: https://www.airandspaceforces.com/article/1100flag/

There's a better longform writeup I saw once from one of the military service academies, but I can't seem to find it now.
I thought it was telling that Andrej immediately "reframed" the question because Lex asked the "wrong question". This is a classic evasion technique one learns from experience and/or media training. Lex's comment immediately after was a clever and gentle dig at Andrej's response.

It seemed like all the "full cost" negatives Andrej mentioned were related to Tesla's ability to execute, and not what would actually produce better results. Tesla would have to be able to reliably procure parts, write reliable firmware, create designs and processes that won't increase unexpected assembly line stops, etc.

Regarding results, the best Andrej can do is, "In this case, we looked at using it and not using it, and the delta was not massive." In other words, the results are better, but not enough to make up for the fact that Telsa can't support additional sensors without incurring a prohibitive amount of additional risk to Tesla. Risk to passengers doesn't appear to be a consideration.
Some versions of the PS3 had PS2 hardware inside, that's how they were able to play PS2 games.
> are in some way related to childhood trauma

I think that view has the risk of being damaging. In particular parents or partners are often misattributed as the “cause”.

1: It leads to victimisation, where people blame their environment rather than fix themselves. We all can find traumatic childhood incidents if we look for them (“repressed” memories can fill in if you didn’t actually have anything obviously traumatic happen).

2: If you suspect trauma and then wonder “what did the parents do”, that is rather unpleasant for the majority of loving parents that didn’t abuse their children whatsoever. All parents make honest mistakes, and any good parent has plenty of unexpunged guilt, usually for no good reason. Also we can be traumatised for entirely mundane events in our lives - where nobody is actually to blame for evil, yet we often look for blame in others.

3: we can’t change our past, so acceptance of what happened is important. Whether we see ourselves as helpless victims or capable actors is critical I think. Creatinig a narrative of victims is unhealthy, in my experience. One of the worst abuses I have seen, was professionals getting a bunch of troubled teenagers together, letting them talk about their extreme trauma together, and then sending them home. Normalising abuse, and it was extremely damaging to the sensitive, empathetic teens in the group (who had their own problems to deal with, and didn’t need to be loaded with other vile shit to process).

4: There are great parents that end up with fucked-up kids, for reasons beyond their control.

I am concentrating on parents here, because although the people I know with your attitude might say they think about the wider picture, often the first thought I see from them is assuming the parents caused the problem - judgy people are very damaging IMHO. I am definitely not accusing you - but I am accusing others I see with a similar attitude. Disclaimer: not a parent, just old enough to have had the opportunity to learn a little from the hurt people in my life, and trying to be wise enough to know how innocently we can all make mistakes.
Yeah, it's literally not good programming if the other people who will maintain it can't work with it. Even if you think they are all idiots. You're not working with some imaginary team of geniuses.

There's not enough of the very smartest to keep the modern world going by themselves, working with your team in the real world is part of the job.

Having read the original article , I disagree that this is a microprocessor - https://web.archive.org/web/20190523172420/http://firstmicro...

I feel this is in line with other computers of that time, and uses rather clever parallel design to improve the performance of the specific functions required - but it is not general purpose by any means.
Which part are you skeptical about?

For example this part:

> Russia got away with annexing Crimea. They invaded again. They demanded that NATO gives up defending about 100 milion people in Eastern Europe (including myself).

has already happened - Russia annexed Crimea, got barely a response from the west so they invaded again and demanded NATO leaves EE countries that got accepted in 90s.

The part about what happens when Russia annexes you is based on how life looks like in occupied Ukraine and in Russia proper. There's more people imprisoned for political reasons in Russia right now than there was in USSR in 50s. And USSR had twice the population. If you call the "special operation" a war or if you take a blank page and stand with it in a city square - you get arrested. Corruption in Russia is also pretty well documented. As is the "2 wars per decade", the conscription and the "sending barely trained recruits to kill and/or die".

The part about Russia invading Baltic states and Poland after they conquer Ukraine was based on Russian propagandists and politicians (including for example Kadyrov) saying it outright in public media.

Some people let life pass them while thinking of one thing that they think is the homerun but they will do it later.. point is go for less than ideal things if going for home runs means never actually getting anywhere. Focus on what you are doing, commit and make sure to do something.
Crime is not distributed evenly across society for both victims or perpetrators, that doesn't mean that we should all become subject to crime as a result. I do believe we should make sentencing more fair and not overly police people on the basis of race or class of course. If someone is caught doing X violent/antisocial crime (including things like burglary or redicivist theft) they should not be left to continue doing it even if they are in a disadvantaged group.

A lot of crimes are not one-offs but something done over and over again until they're caught. This applies for both (sexual) assault and property theft. Laws against those need to be enforced even if the first X don't involve prison, because the people stealing hundreds of dollars of merch every week or picking fights are making their communities worse in systemic ways, and after a certain point separation from society is the only way to protect everybody else from the antisocial behavior (and serve as a deterrent).

No, I am not affected by a single instance of someone taking candy from Walgreens. But I am when so much theft occurs that everything valuable is locked up, when prices are raised to account for shrinkage, or when retail operations close down. I am when I have to tell people to leave nothing in their car and not to park in certain spots with frequent breakins, or when I can't leave my bike locked up outside even for a few minutes, or when I can't get packages delivered to my address anymore because it will be immediately stolen if I'm not there.

The victims in aggregate aren't just the people or businesses being stolen from, but all the other people in the community who subsequently have to live in a food desert, pay high prices, or can't even get deliveries any more because there is so much theft.

Scandinavian countries have generous social systems which reduce the demand for crime in the first place. We could have that too.
By removing and replacing entire walls, you are missing out on most of the difficult parts of texture and paint matching (and "just paint the whole wall" quickly turns into "paint the whole room" in some cases). I suppose you could make the argument that we should then just rip out the entire wall to run a single cable, but I personally think that's extreme both in cost and disruption.

I'm glad you had such an easy time of it, but cutting, patching, and matching is a pain in most homes I've done it in. And don't even get me started on lath and plaster.
I don’t think so.

The current reckless course has us replacing stable base load with intermittent sources before we have any storage solution. That means you need to massively overbuild generation and transmission capacity to meet reliability requirements.

Electricity prices are set to greatly increase if we stay on the same path.

Of course, your friendly regulated utility loves this as they make a set % on assets they own. They could careless about efficient generation. More assets = better returns for their investors.

Plus by the time it gets through congress and into written law the big tech lawyers will have riddled it with ways to suppress their competition and have it so complex/involved that only a large company could follow it (see: the bills following 'too-big-too fail' that merely reduced the number of big banks to 5 and hundreds of midsized ones could no longer deal with the new capital requirements).

I'm just trying to imagine how awful the standard will be, or how selective the enforcement will be, how some new technological development happens but adoption gets crippled by a policy written for the Facebook era, etc, etc.

There's always tons of downsides that outweigh these heavy handed interventions.
"Cite your sources as to why torturing prisoners is wrong" is simply shorthand for "I actually like the idea of this torture and you can't tell me otherwise". Like I said, I can't make an argument as to why you should care about your fellow human if you don't already. It's not a good faith question.

We know that punitive measures do not act as a deterrence and in the case of more progressive countries that have wildly better outcomes we know what actually has good outcomes. If you're really interested all the literature is just a google away. Check out US incarceration and recidivism rates (which are the worst in the world) and those of more progressive countries. The data is all there for you, if you are curious. We've seen what doesn't work, and we've seen what does. It's not my job to educate you.

Like I said, I'm not here to convince you of anything. I cannot change your value system, I can only make a public example of why it does no good to drag us into the past, and all the atrocities that entails.

EDIT: sort of an afterthought, but for those reading I always find it hilarious that whenever a reactionary sees something work in another country the first instinct is to say "actually the US might exist in a bizarro reality where everything is opposite, and you can't prove that it's not so ha". As if the most scientific approach to seeing someone's repeated successful results is to absolutely refuse to try to replicate it yourself!
That's a common retort, and it's complete nonsense.

> the experience of other societies which incarcerate a much, much smaller part of the population indicates that most people in USA prisons are not there because of this reason.

This does not track. People like to point to Norway as a model for rehabilition and low incarceration rates, while completely ignoring the fact that their crime rate is one of the lowest on the planet.

So, yes, if your crime rate (and anti-sociality) is near zero, I would expect the incarceration rate to be much lower, as well.
We had our loft converted last year, and after watching the builders construct the partitioning walls, I think I would probably manage that. We also had to have some walls removed and re-built and made the house too dusty for the kids to be around. This house is an old English terraced house, and lots of the non-retaining walls are wooden lath and plaster, with horse hair mixed in for good measure!
Tell HN: WhatsApp appears to be censoring references to Signal
I don't usually go in for conspiracy theories, but this one seems pretty clear-cut and I can't see anyone else discussing it online: WhatsApp appears to be selectively censoring references to Signal.

Specifically, I had changed my profile picture on WhatsApp to the Signal logo and my ‘About’ text to ‘Message me on Signal - https://signal.org/download/’. However, I noticed recently (after someone happened to open their WhatsApp in front of me and I saw their chat with me) that my WhatsApp contacts are seeing my profile picture and my ‘About’ text as blank. I've checked and this seems to be the case for all of my WhatsApp contacts.

See screenshots from me and my friend's phones here: https://imgur.com/a/qvEsswW

On the bright side, this serves as an ideal demo for convincing anyone who doesn't understand why I am trying to migrate them over to Signal. So, I guess, thanks Meta?

It's really not. It's very hard to argue against a technological system that worked really well for as long as it did; only to be disrupted by the internet.

Honestly, it's hard to quantify how well it worked because we got so used to it; it stopped being "technology" and just became "part of life."
It's because the house builders don't do the job properly and install MVHR, which not only removes the excess humidity, but also recovers most of the energy of vaporisation.
It's weird that they didn't think of the simplest solution, which is to use the speedometer, and instead chose to use GPS. I suppose that makes it so you can't even use the nav if you happen to be riding on a https://en.wikipedia.org/wiki/Roll-on/roll-off .
Real life performance of vision only stack doesn’t agree with it.
Common hobbyist wisdom is that you use a longer lens to make the subject feel closer without coming closer. This is subtly wrong. In the eye of the viewer the distance eliminated through focal length is felt in a different way. If you want a photo that takes you back to being close to someone, come close and use a wider lens.
It's not just the people the murderer already killed, it's all his other potential victims, now that he has demonstrated himself to be willing and able to take innocent human lives.
No, it's over. Look, the LIDAR value proposition was necessarily "Yes, we're outrageously expensive and involve major tradeoffs in physical design of the vehicle, but vision can simply never do what we do". And... vision does. It does, every day. On hundreds of thousands of cars.

In point of fact FSD beta vehicles are out there every day in environments where LIDAR has never been deployed, nor likely ever tested. And we're not seeing clear "it can't do this" failures. Anywhere.

The closest you're going to get to evidence against vision are things like that "It Hit A Kid!" stunt from a few months back that turned out to be basically faked[1].

[1] At least the perps went silent and no one was ever able to reproduce. I mean the whole idea was ridiculous: my car twitches at pedestrians, including kids, including my kids, every day. It literally draws them on the screen.
Not just risk to passengers, risk to any thing in proximity to the vehicle while it is in motion.

Maybe just one or two hot water bottles? [1] We use them in Winter to warm our feet in bed. But they are very versatile and can also be used to alleviate any kind of tension.

I also use one while I code: I put it inside of a small (baby-)sleeping bag wrapped around my feet. Sounds weird, but it's so comfortable!

Perhaps a sunroom may be a better word in this case, in the U.K. a conservatory is a recreational room with large amounts of glass built to face the sun. So one can enjoy the sun and brightness of a sunny day without having to go outside if it’s not warm, or too windy. Frequently they’ll open onto a patio or other paved outdoor space and from there into the garden proper.
> fat events because fat events don't usually store a snapshot of the entire world. They're often actually delta events, forcing the consumer to rely on caching (a racey affair) or just fall back to hitting the API anyway.

I think you're saying "I don't like fat events because they're not really fat events", well, sorry that's your experience, I don't think that's a valid criticism of the actual thing at all, just of your poor experience of it.

> Data races can occur with fat events.. hitting the API anyway.

That happens with thin events as a matter of course, right? You stated that thin events are "lot less prone to data races" and now you're saying that they're the same? Where's the fat-event-specific issue that you alluded to? Citation not provided.

> Having the event consumer pull data is usually a trivial cost difference.

As I have stated twice before, it's a non-trivial _reliability_ difference, and that's the key.
Couple points: (1) of course YC cares about hardware startups; (2) there's no connection between that and HN's front page either way.
Haha. American here. I still remember when I moved to Austin from Boston. Even within America Texas is a fairly friendly, outgoing place. At least compared to metro living on the East Coast.

The culture shock was noticeable. In Boston if a stranger walked up to me to say something my feet would already be pointed in the direction in which I intended to walk away from them. Whereas in Austin people are far more friendly, outgoing, and open to impromptu social interactions. I found it a very welcome change.

My theory is that such attitudes are heavily influenced by population density. If you live in a city that is packed full of people you start to guard yourself against the number of daily social interactions you will allow. For many, it’s emotionally draining to constantly acknowledge, say hello to, chat with, or humor every person that you meet. When you commute on the train every morning that becomes quiet time for you, even when you’re in a train car full of other commuters. It’s generally considered rude to chat up people too much. At least don’t be surprised when people want to keep to themselves.

Whereas in Texas and parts of the American midwest there is less need for people to live right on top of one another. Everyone travels alone by car, walking is less common. Meeting strangers in public is then less of an imposition and generally more of a warm-hearted experience.
> Should, but don't, is not doing their job. Most engineers don't have the luxury of using this defense their day to day job. Yeah, I should be doing testing, but I don't know. I should be writing clean code, but I don't know. I should be communicating with my colleagues, but I don't know.

This is needlessly antagonistic. All teams have gaps, but effective teams help each other out. For instance, a good manager will give you air cover when things are underestimated or unforeseen difficulties arrive. Similarly, good engineers will point out risks and potential problems even if it is not directly in their execution path.

The most toxic teams are ones where everyone keeps their head down and looks for every opportunity to say "not my job" whenever any larger or unusual challenges are identified. Based on your comment it seems like you think that ICs can't get away with this, but managers can, and I assure you that neither is true.
