> There are ~900,000 police officers in the United States, and 240 million 911 calls, and 50 million police-public interactions. That's an average of over 50 interactions per day for a police officer.

Those are numbers per year, not per day.
Since this will inevitably turn to a discussion of opioids, here are some counter-narrative facts that surprised me:

1. The narrative is that some poor guy took pain meds for a legimate reason then ended up addicted. While this does occur, it's actually not very common.

> Among people who are prescribed opioids, addiction is relatively uncommon. The percentage of patients who become addicted after taking opioids for chronic pain is measured in the single digits; studies show an incidence from less than 1 percent to 8 percent. Most of the estimates are skewed toward the low end of this range, when those at risk (due to a history of substance abuse or, to a lesser but meaningful extent, a concurrent mental illness) are removed from the sample.

2. Most addicts had a history of drug abuse.

> People who abuse pills are rarely new to drugs. The federal government’s 2014 National Survey on Drug Use and Health, for example, revealed that more than three-fourths of misusers had used non-prescribed benzodiazepines, such as Valium or Xanax, or inhalants. A study of Oxycontin users in treatment found that they “were not naive individuals with accidental addictions who were introduced to painkillers by their physicians as reported by the media … [Instead they had] extensive drug use histories.”

It's hard to bring this up without straying into classism or victim blaming. The reality is that most people without comorbidities and abuse history are quite safe, and these are drugs we need.

I got an email from my electric utility this summer, pointing out that I was using MASSIVELY more electricity than the same month last year. Like, roughly triple.

When I was at work every day, I had my HVAC on a pretty drastic setback; no sense cooling an empty house. I guess it worked pretty well! Because this year I was home all summer and despite not wearing pants most of the time, it still took a fair bit of power to keep things not-sweaty.
It is hard to tell. But I actually liked your dismissal. So concise.

Currently people often use these code block-ish things for quoting text, for lack of a better option.

This is completely unreadable on mobile for lines of any significant length, because the block itself is a box about half the width of the screen that doesn't wrap and must be scrolled horizontally.

Minimal features and css are all well and good as long as they work properly ;)
Or... they could just modify the API a little and keep the guy who has learned something that didn't really cost them anything, and that a new hire is unlikely to know.

But you are right, corporations do usually prefer to behave in a psychopathic manner.
There are also those who think both options are valuable.

A lot of the polarization to me seems like it stems from the fear that one threatens the other.
"Thank you for your time."
Along these lines, in Probability Theory: The Logic of Science Jaynes suggests thinking in decibels (which are just log probabilities). Here are some excerpts of this:

"... it is very cogent to give evidence in decibels. When probabilities approach one or zero, our intuition doesn't work very well. Does the difference between the probability of 0.999 and 0.9999 mean a great deal to you? It certainly doesn't to the writer. But after living with this for only a short while, the difference between evidence of plus 30 db and plus 40 db does have a clear meaning to us. It's now in a scale which our minds comprehend naturally... In the original acoustical applications, it was introduced so that a 1 db change perceptible to our ears. With a little familiarity and a little introspection, we think that the reader will agree that a 1 db change in evidence is about the smallest increment of plausibility that is perceptible to our intuition."

"... What probability would you assign to the hypothesis that Mr Smith has perfect extrasensory perception? ... To say zero is too dogmatic. According to our theory, this means that we are never going to allow [our] mind to be changed by any amount of evidence, and we don't really want that. But where is our strength of belief in a proposition like this?

"... We have an intuitive feeling for plausibility only when it's not too far from 0db. We get fairly definite feelings that something is more than likely to be so or less likely to be so. So the trick is to imagine an experiment. How much evidence would it take to bring your state of belief up to the place where you felt very perplexed and unsure about it? Not to the place where you believed it -- that would overshoot the mark, and again we'd lose our resolving power. How much evidence would it take to bring you just up to the point where you were beginning to consider the possibility seriously?

"So, we consider Mr Smith, who says he has ESP, and we will write down some numbers from one to ten on a piece of paper and ask him to guess which numbers we've written down. We'll take the usual precautions to make sure against other ways of finding out. If he guesses the first number correctly, of course we will all say 'you're a very lucky person, but I don't believe you have ESP'. And if he guesses two numbers correctly, we'll still say 'you're a very lucky person, but I still don't believe you have ESP'. By the time he's guessed four numbers correctly -- well, I still wouldn't believe it. So my state of belief is certainly lower than -40 db.

"How many numbers would he have to guess correctly before you would really seriously consider the hypothesis that he has extrasensory perception? In my own case, I think somewhere around ten. My personal state of belief is, therefore, about -100 db. You could talk me into a +-10db change, and perhaps as much as +-30 db, but not much more than that."

> It seems likely that this will cause ride-sharing not to be economically feasible in rural areas where per-driver utilization is low.

Or they will have to make allowances for areas that have very low supply and/or supply that is very dispersed. For example, charging for some/all of the the time/distance from the driver's origination point to the pickup point. That will necessarily make ride sharing more expensive in those places, but that's because providing rides in those places is more expensive.

Another option that might work in tandem is to allow drivers to log in as a sort of "if the offer is good enough I'll take it" sort of tier, and then you might get a lot more people in rural areas signed in in that state, and while any one potential driver might reject, a lot more eyes might see it that wouldn't bother to have been looking before, and that might make cheaper rides more likely as closer people are logged in as potential drivers. It's worth noting something like this might also have kept Uber/Lyft from having to classify the drivers as employees in the first place, since as I understand it choice of work is a big part of why they didn't qualify as contractors.

> It's also possible they'll decide they won't want to dilute their brands by offering a service which makes you wait 7 minutes for a ride.

7 minutes is actually on the lowest end I've seen where I live, and that's in a metro area of ~250k people. Usually it seems to be around 15-20 minutes. Maybe it's just particularly slow around here, but my guess is that you don't get under 10 minute pickup times on average anywhere except for major cities.
It's common in Europe but didn't quite catch on in the milder US states, maybe it will now.

It's actually a nice concept, but NY state and North it won't work every day, and unlike 'breaking for rain'. there are long periods of at least several days, sometimes weeks, where it's 'too dam cold' which makes it really hard to operate, i.e. 'just on the nice days'.

And FYI for the skiiers chiming in, it's not the same thing. Skiiers are already 'being active', they're bundled up and prepared for cold, and 'doing an outdoor activity'.

That said - Montreal 'defeats winter' with weekend long raves in the dead of winter, getting more 'bundled up' for 'outdoor dining' might possibly be a cultural shift that could be made if enough people were on board and it became 'a thing'.
WFH Fridays Off
I currently work for a medium-large SaaS where all employees are WFH during the pandemic.

During the summer months, we were given Friday's off as it was recognized that each employee was probably putting in more hours during the workday and it would be a good initiative for mental health (hot take: it was great!).

When September rolled around, the company decided to switch to every other Friday off. This seemed like a fair compromise to balance productivity, an aggressive cadence and remain competitive. It's been pretty good for the most part.

End of October and this policy of every other Fridays off is due to expire. Management is looking for feedback as to why we should keep it, what are the benefits, how it has personally impacted us, etc. So we submitted feedback up the chain.

This got me thinking, I have seen several SaaS companies have kept these reduced work hours (mostly large ones, but several medium and many small). Are reduced hours (i.e. 4 day weeks, or every other Fridays) something your company is working with? have they kept/removed the policy? Did it impact your release cycle, quality or productivity?

Don't get me wrong, I am grateful for the time off and in a good position overall. Just curious as to where the industry is headed.

The point is that ramsomware is only written because hackers can get high payouts. If the penalty for paying a ransom is higher than the costs of not paying the ransom (and losing the associated data), then no one pays the ransom, and if no one pays the ransom, no one makes ransomware (or at least no one targets institutions who can't pay ransoms).

I believe this is discussed in Schelling's book "Strategy of Conflict", which I've never read but has been much discussed online[1]. Indeed the article I've linked specifically mentions this case.

KeePassXC 2.6.2 does not have 128-bit limit for passwords you save. I don't know if the previous versions had because I have not tested.
Said another way:

- You have a system whereby every instance has a 75%-79% uptime.

- Each instance's 21%-25% daily scheduled maintenance window can (generally) be arbitrarily-scheduled by the ops team.

How do you near guarantee that there's always one instance available?

If you said:

"manage a redundant cluster of at least 2 instances with non-overlapping maintenance windows"

Then you were correct!

> You're still not getting the point - which is you're not the customer Apple is trying to sell to

Funny how they keep sending me marketing emails though.

This is kind of a weird notion, that Apple doesn't want me as a customer, as I've spent more $ on Apple products in my life than the majority of people.

> This is your opinion.

Does this really need to be said? Of course it is! Why would I state someone else's opinion?

> Steve Jobs himself never wanted to sell "computers which only nerds could use".

This is a straw man argument. I already mentioned that I preferred Apple under Steve Jobs to Apple under Tim Cook. They're not the same. Jobs said, "the computer is the most remarkable tool that we’ve ever come up with. It’s the equivalent of a bicycle for our minds." For Tim Cook, though, computers seem more like a bike lock for the mind.

> Super customizability that you want was never their product!

Again, I'm comparing Macs today to Macs literally only 10 years ago. Those products existed. It's historical revisionism to claim that current Apple is exactly the same as past Apple. It's not. Not at all.

The strangest thing about the argument "this is the way Apple has always been" is that the linked article of this HN post is talking about a new change that hasn't even shipped yet but exists in the Big Sur beta. It's a completely novel macOS behavior, not the way the Mac has ever behaved, so it's just bizarre to argue in this case "that's just the way Apple has always been". Apple is changing... for the worse IMO.

Then use a client which makes things look like that! You can specify annotate your code snippets in the Gemtext markup format, you know, just encourage people to put "lang:C" or "lang:Go" there and write a client which adds highlighting.

AR Copy and Paste – photograph something physical and paste it into a document
I think as someone who has evaluated functional Typescript, ReasonML, and purescript, I can say that ReasonML provides the best developer experience (interop with the JS/TS ecosystem) while providing the next generation of type safety and composability for backend development. Unfortunately the ReScript branding is probably going to be a lot more confusion (more-so than the dual bucklescript/reasonml branding). To make it even more confusing, ReasonML technically isn't dead (only Reasonml.org is) and is now a third syntax (in addition to rescript and ocaml).

Also I don't know why these languages aren't being promoted more for backend development as it's a perfect fit for the paradigms espoused in https://pragprog.com/titles/swdddf/domain-modeling-made-func.... I would say Ocaml/ReasonML is even more ergonomic than F# (polymorphic variants are great for composable error handling).

Even in the current state, ReasonML can be used to progressively enhance a JS or even typescript codebase with no need to fully buy into a rewrite or even heavy toolchain modifications.
Also, Minecraft is expensive (at the current price and exchange rates, it's 15% of the minimum wage here), and currently you have to buy the Java and Bedrock editions separately. If this change means that you can use the same account for the Java Edition and the Bedrock Edition, that means you're getting the other edition for free.

What worries me is if this change is a prelude to adding some sort of copy protection to the Java edition (beyond requiring a valid account login before downloading the game or connecting to a server).
Indoor restaurants aren’t allowed at the moment, so if people want to go out... I can’t see it continuing all the way through the winter, though; while it doesn’t get very cold here (minimum of about 0 C usually) it does get very windy.

And all restaurants, even outdoors, are banned for the next six weeks, anyway.

Ask HN: How can I help my son into a CS career who is struggling at college?
I’m struggling with how to help my son.

He seemingly lives to program but has struggled with college, especially on the timed tests, even though he feels he knows the material. Because of this, he just feels like his goal of getting a degree and then a career is becoming unobtainable. He’s always said he just wants a mentor or something who could appreciate his work and help him along with being a better developer.

I guess what I’d like to know is: are there any non-untraditional avenues for getting a degree and getting into the industry?
Indeed. Huygens also is responsible in large part for the use of math in physics and also experimented with early internal combustion engines - criminally underappreciated!

Ouf that survey is weak - being a millionaire in the US does not make one wealthy. A lot of people end up having more than 1mil in assets by the time they retire simply due to real estate, this isn't the case for everyone but being a millionaire doesn't mean you're not still somewhere around the midpoint of the middle class in terms of income.
Seems to me the heft of the problem falls in forcing drivers to either explicitly consent to agreeing with the platform's views by selecting "Yes on 22" or to communicate their ambivalence by selecting "OK" in the dialogue that is presented to them in the driver app.

If Uber just presented an explanation of the issues and allowed drivers to decide for themselves without any way for the platform to track their decision, no problem.
Not usually, no. But applying formatting on top of selection is another rich text benefit: with text selected cmd-B makes it bold, shift-8 just replaces the selection with an asterisk (in a standard text field)
Call me oldfashioned (despite being early 30s), but hot desking does not sound appealing to me. I want to feel like I have a space that's mine at work.

Where would I store my work papers? Right now at my work desk I have a little library of technical books. What about putting up pictures of family? Decorations during holidays? The older I get the more these things are important to me, as silly as they may sound. Perhaps it's because work becomes a larger and larger portion of my life. When I was fresh out of school it kind of felt like something I did for X hours before coming home to my "real" life, like a pseudo-school environment. But as time passes (and if you like where you work), work can become a bit of a second family. Having my own space adds a sense of belonging and stability that really acts to boost my productivity and sense of team commitment. I did something that that basically amounted to hot desking at a previous job and I found it miserable. I never felt settled.

Perhaps there is some sort of introvert/extrovert thing going on. I am social and love my coworkers but at heart I'm an introvert; having my little space gives me a sense of being able to retreat a bit. Paradoxically that improves my sense of belonging -- it begins to feel a bit homey. Maybe extroverts are able to fully get their sense of belonging just from being around people.

I do think that flexibility will probably be the way forward. If Bob wants to be full time remote, and Mary wants to be a hybrid, totally reasonable. I would just seriously miss "my" space.

> So the bad guys used a public ledger (Bitcoin) to get paid? Why aren't the hackers asking for cryptocurrencies using zero-knowledge proofs like ZCash or Monero? Bitcoin? What's their plan next?

I imagine they chose Bitcoin because it's the most liquid - they can just tell their victims to go to Coinbase or any cryptocurrency exchange to acquire it. If they ask for Zcash, the options are a lot more slim.
