I think it was on a post about FBI surveillance, someone pointed out that one of the big advantages of all of these surveillance methods are not just that they may miss some cases, but that they are much cheaper than lawful interventions. I would venture to say that if we spent more on pursuing issues that actually matter (not most drug crimes) we would be able to do better while ensuring a greater general level of privacy than we do right now, while also solving more problems.

edit: I realize I wasn't clear what the more serious problems I'm referencing are. They are human trafficking, murder, domestic abuse and so on.
Thank you so much for this. Very well delivered.
You’re not missing something. But that’s the point. You read the whole comment and interpreted it in good faith. What the comment you are replying to is saying, is that it is easy to cherry pick statements out of nuanced comments that do not hold up well on their own. So unfortunately many people are afraid of making nuanced points online, and stick to banal platitudes that can’t be easily misinterpreted in bad faith.
Ask HN: How have you dealt with workaholism?
For folks who can feel addicted to jobs, how do you cope? I sometimes struggle with taking on too much somewhat compulsively. I begin to get addicted to the attention and accomplishment, little else can matter. The tech world seems to value this high level of compulsive work where we lose touch with ourselves as human beings and sacrifice relationships and precious time In Life.

If you have faced this level of compulsive work, how have you coped or overcome the issue?
The way I've always heard it:

We judge others by their actions. We judge ourselves by our intentions.
Yeah, same thing happened in New York. All these people moved in without any respect for what NYC is really about -- Dutch farming.
At least until the rest of the PC world moves to ARM.

'I have suspected for years that the STEM fields posed the most dangerous threat possible to the unopposed dominance of politically correct sociological idiocy over the entirety of the university environment, basing their claim to validity on recognition of something approximating a universally accessible objective reality.

...

But, make no mistake about it, scientists, technologists, engineers and mathematicians: your famous immunity to political concerns will not protect you against what is coming fast over the next five or so years: wake up, pay attention, or perish, along with your legacy. Whatever you might offer the broader culture in terms of general value will be swept aside with little caution by those who regard the very axioms of your field as intolerable truly because of the difficulty in comprehending them and considered publicly as unacceptably exclusionary, unitary and unconcerned with sociological “realities.”'

Ask HN: How to write a good technical article?

Normally, zero-copy refers to the fact that data can be decoded without copying it in memory. I.e. a pointer cast is zero-copy because there's no need to copy the memory elsewhere; that memory can simply be reinterpreted as the target type.

I'm not sure if that's the same meaning in this context, however.
I have a similar experience, I'm typing this on my 2013 MacBook Pro, I don't notice any significance performance issue, and all the hardware is still intact, it's really amazing. This was my first Mac, I'll 100% sure buy another one when this one decides to finally retire.
The authors of the paper do various calculations to arrive at 36.

How do they determine f_l, the probability of life originating on a suitable planet?

They follow the "Principle of Mediocrity", ie life exists on Earth, and we are not special, so probably it exists anywhere it can exist and f_l = 1.

This is the exact opposite of the Anthropic Principle, which says (correctly) that we cannot deduce anything about the probability of life originating from the fact of our own existence.

If f_l isn't 1, and it's some smaller number, like 1^-1000, then there won't be 36 alien civilisations in the galaxy - there will only be zero.

Even in the observable universe, there will be zero alien civilisations.
In Japan's case, definitely not true.
That property is called phonemic orthography, and some examples include Finnish, Turkish and Esperanto.
> And what about Nigerians who come to the U.S. and don’t succeed? Wey, the activist chef, says there’s a lot of pressure to fit a certain mold when you’re Nigerian.

Sounds like pretty common immigrant culture.

Personally, I find linear regression makes more sense from an orthogonality of sub-spaces perspective. That the same solution can be derived as the optimum of some cost function is neat though.
Wasn't meant to read as hubris, I genuinely was curious (if a little unclear).

FWIW I have read about this at length generally at a local level, living and working next to a couple of bridges with this issue. A high tech approach has been tried and abandoned with these bridges as they were (fatally) not effective (though not this high-tech). I naturally assumed there was some particular reason for the tunnel.

I read the rest of the thread before I commented, the ones you point out were written after, and they do indeed go some way toward explaining that particular issue at that particular tunnel. The original post did not explain anything but the bad road design.

While we are giving friendly advice, your comments may be better received if you gave them in a spirit of generosity, as I have taken yours, rather than jumping straight to judgements and epithets.
This is an unsolved problem in computer science. I hope you solve it!

My flatmate tried to "compressed air" his laptop once using his lab's compressor. Didn't turn the laptop off. Only two fan blades survived.

We glued the other blades back on to tide him over until a replacement arrived, but each day one or two would break off and we'd have to give the laptop a good shake to expel them.

...it's often difficult to know how precise one must be when advising flatmates about compressed air.

The receiver would be much, much bigger than a square kilometer by many (>6) orders of magnitude. Any civilization capable of interstellar travel would be very capable of setting up a planetary or solar system sized astronomical interferometer (aka hypertelescope [1]) using a large fleet of synchronized satellites. These satellites can be prototyped with today's technology and any interstellar civilization would be capable of both receivers and transmitters with far more power than we have attempted today.

Really cool job, but.... dear god what a ridiculous regulation.
I hope this is sarcasm.
Yes, it sure is confusing why say NYC had a times 5000-6000 new cases a day and yet Tokyo, a city with 2-3x more people and way more crowded trains and offices and stores never had more than 200 a day.

People come up with all kinds of theories but none of them seem to fit. One theory, Japanese wear masks. They didn't until the lockdown which was late. They've mostly unlocked now and restaurants seem relatively busy. Of course (almost) everyone is still wearing a mask and lots of precautions are in place but at a glance seeing the still crowded trains and now crowded restaurants it's hard to figure out why the numbers stay so low.

Some people claim not enough testing but if that's all it was there would still be a death rate climb and arguably an ICU overflow and that hasn't happened either.
Yes, exactly. There's a fantastically good book about domestic abuse, "Why Does He Do That?" In it, he takes great pains to make clear that abusers are not abusers because they're mentally ill. They do it because they get something out of it. Exactly what varies from person to person, of course. It's the same with a lot of anti-social behavior.
I always wonder why owners of those RVs are considered part of the problem. They are not on the streets. Most of them do not pollute the streets either. Those who are should be contacted for appropriate enforcement. They likely can afford to pay for a traditional housing unit far away but choose to be closer to their work. Spending 2-4 hours in traffic daily just to go to bed makes no sense as a single person.

I choose to not pay rent since 2015. I make enough money to at least split an apartment with someone, but I see no benefit in doing so. All my stuff is either sold or in storage. I only need a parking spot where to park my vehicle. My minivan converts into a 8x4x4' bedroom and many people walk past it without giving it a second look.

If a city wants to provide a secure parking lot, that is great and I'd certainly park there, but otherwise I have no need for their help. The challenge with this is that whenever such things are mentioned, the city wants to add arbitrary rules. Opponents then at times label secure parking zones as concentration camps.

We need to get people without a tent off the street. They are definitely in danger. Those in tents can be remarkably comfortable with the right gear, but they need land to set them up and the right gear is expensive. They likely don't have it. Sidewalks are not the right land for that, so they need special attention.

Those of us in vehicles are comfortable enough to not be concerned with. If we are able to maintain a registered insured vehicle, that suggests we do not have mental problems.
Ugh, I realized I misunderstood your comment above. I agree with you.
Credit goes to the Engineers, not the company.

Engineers are told what to do, they execute.

Regressions in the OS is something you can blame the company for. Management decisions are not done by Engineers, they are executed by Engineers.
What can someone facing these issues at work do other than leaving the job(assuming they are not in a position to just quit)? Are there any legal recourses available in your country? If yes, are they worth pursuing?

I prefer it primarily because it "just works". I don't use my TV often these days, so I stopped maintaining all my custom hardware (e.g., Retro Pie). I've found that my Chromecast can be finicky; sometimes it doesn't like to stay connected to Wi-Fi--and it has no excuse, seeing how I'm using Google Wifi.

That being said, I do like the UI. I don't mess with it much, though; I mostly just talk to it. It does a fairly good job of figuring out what show I'm telling it to play. It works, it updates on its own, it doesn't brick itself, it doesn't disconnect from the network (because it's wired in), it's reasonably secure, it plays what I tell it to play. Good enough for me.

Depending on your use case, you might want to give Kodi a try if you're not satisfied with the mainstream alternatives. I haven't used it in ages, but I hear it works quite well these days.
There are 17 million vacant homes in the US[0]. With the exception of the half a million of us that are homeless at any given time[1] we all live in one of the other 121,520,180 homes that currently exist in the country. How much housing is enough? What if instead of focusing on how much of the population we can cram into the fewest (constantly under construction) places we figured out ways to incentivize commercial development and rehabilitation of derelict communities?

> All aircraft must be flown in

That's very weird. For example, small airplanes get from the US mainland to Hawaii in shipping containers. Two Cessna 152s fit in one container, or one 172.
I can cut a long drive in half or by two-thirds in what are considered slow (read: beginner-friendly) single-engine airplanes.

You take on an entirely different relationship with the weather.

Flying into expected congestion beats driving any time. I really enjoy flying to college football games, where just getting out of town afterward may take 90 minutes or more and then the rest of the trip home.

It creates flexibility and opens up options that road travel does not. I can get to the beach in two hours from where I live, making a day trip for fresh seafood doable. My son was in Auburn last year for the Tennessee game. Another couple flew down with me; we picked him up in Auburn and thence headed to Tuscaloosa. He got to watch four SEC teams play each other live in the same day.

Charities Pilots N Paws and Angel Flight transport rescue animals to their forever homes and vulnerable medical patients to and from treatments.

Fewer interactions with TSA creeps.

Maintaining my required medical certificate and protecting my investment in flight training creates a strong incentive to stay healthy. I’m in my best shape in decades. Of course it’s possible to find overweight pilots.

If you intend to fly to any sort of scheduled event, strongly consider adding an instrument rating, which will make you a much safer, more precise pilot and should increase your likelihood of surviving inadvertent flight into IMC.

It’s a rewarding intellectual and physical challenge. Phil Greenspun posits[0] that it keeps the mind active and young longer.

If you go to the local general aviation airport, you'll find lots of guys in their 60s and 70s who are tackling challenges that are way beyond your own capabilities. Certainly these guys are much sharper and in better mental and physical shape than the average person of their age. Flying requires mental acuity and real-time decision-making that seems to keep pilots young. A lot of older folks seem to be preoccupied with trivial matters, such as organizing their junk mail or minutia within their childrens' lives. Old pilots don't seem to be subject to these preoccupations and the topics of their conversations have more in common with young pilots than with other old people.

The cops that stay home because police are being held accountable for their brutality should stay home permanently -- without a job.
I have Dutch ancestry, my ancestors were some of the first generations to settle in NY and I grew up there. Truth is that those generations of immigrants that came before the "tech workers" do have respect for what NYC is really about. They made NYC what it is. Just another opinion.
What's more important here is that the title doesn't match the conclusion. (That being said, it's kind of cool that they A/B test all their titles like that--thanks for the info!)
I recently had fun cancelling my Comcast internet after switching to fiber. When asked why, I said "4x the download speed and 20x the upload speed for half the price". The tech just said "can't argue with that..."
What motivated you to get started?
"How to Program an Infinite Abacus" defines register machines (a.k.a counter machines), and shows that they coincide with general recursive functions. "The complexity of loop programs" defines loop programs, and shows that the coincide with primitive recursive functions. (A key difference is whether loops are bounded or not.)
I was the third generation to live in our house growing up. When my grandparents moved there they tell the story like there were gravel roads and no traffic lights. Today there’s a Washington, DC Metro station (Well it supposedly opens in a few months time). There are bike lanes. And tech companies. And apartments. And to be honest I think the area is better off for it. It’s certainly better than destroying even more forest and farm land for ever expanding suburbia.

That could also be part of the reason they are switching platforms. Likely not the primary one.
Sounds like there's a point to be made for referential integrity too. That is, if a struct contains string A twice, when you read it back in you'd want both those pointers to be identical. You'd get this for free with Cap'n Proto, but it would require extra care with "one-copy" or looser definitions of "zero-copy."

I have a T500 Core2Duo T5600 w 4GB RAM sitting in the cupboard. I pulled it out and put an SSD in it and installed Lubuntu, works fine but I have some software licenses I’ve paid for that are only available on MacOS & Windows.

Do you think it would run Windows 10 ok? I’d need to buy a license, but at this stage that might be cheaper than a new / secondhand laptop.
You know what, you're right. What would be even more effective is if each person had a camera and microphone embedded into their bodies that uploaded all data directly to the government. Then it would be impossible to commit a crime and get away with it, and we would need far less police!
You actually can pilot a plane without a license after some instruction and passing a medical exam. The main thing getting a license changes is the ability to fly others.
Apple actually built a way out, but they haven't advertised it, publicized it, nor marketed it under these terms. They probably don't even want people thinking about it.

I have not just one, but three active podcast subscriptions that I initiated through Apple Pay just this past year including one to Siracusa's podcast, and I did so through Safari. There's your IAP alternative for payment processing right there that doesn't rely on giving Apple a 15-30% cut, nor giving your credit card details to every fly-by-night crapware peddler.

EDIT: Also I just remembered, I believe this is also how I initiated a yearly subscription for a newsletter/podcast vendor hosted on Substack. For that matter, you can pre-order a Tesla Cybertruck using Apple Pay, I haven't, but it was an option on the order page.
