> Cryptography has rules, which are both simpler and more fundamental than we might think.

<Proceeds to describe Cryptography in a way that confirms that it is exactly as complex as I set it out in my head>

e.g. from just the first pagraph:

> " Never ignore timings, they're part of most threat models."

> On most CPUs, the timing side channel can be eliminated by removing all secret dependent branches and all secret dependent indices.

> Some CPUs also have variable time arithmetic operations.

> Watch out for multiplications and shifts by variable amounts in particular.

Yeah dude, stuff like this is EXACTLY what most people don't want to think about, and shouldn't have to think about, and which is why the guidance is "don't roll your own".

I reject his premise as well that this guidance prevents good people from pursuing Crypto as a field of study - as far as I can tell it's not discouraging anyone with actual interest in it.

>The plot to spirit Ghosn out of Japan was one of the most brazen and well-orchestrated escape acts in recent history, involving a dizzying array of hotel meetups, bullet train travel, fake personas, and the chartering of a private jet.”

What a fascinating read that just makes you wonder how frequently acts like this occur in the background and doesn't get picked up in the news.
Service workers have been around for a while. As far as I know their capabilities are restricted to the domain that includes them. So the guardian website can only intercept network requests made from itself.
What about something like Kerbal Space Program? Orbital mechanics can get pretty dry, but a game like that can allow us to “play” with concepts and build intuition that we would otherwise have to do problem sets ad nauseum.
Hand surface area is often given as 1% of body surface area (1.5-2 m^2), i.e. 150-200 cm^2, unclear if one or both hands but I assume one. I've also found claims of 400 cm^2 for one hand.

Methanol penetration is predicted at 2.0 mg/cm2/h" would imply that assuming two hands of 800 cm^2 total, exposed to methanol "hand sanitizer" for 5 minutes, would absorb 133 mg of methanol.

I think the skin absorption issue is a red herring and the real issue is that people keep drinking it.
I thought the "low sample size, checkmate!" without any other analysis was limited to Reddit dilettantes.
As someone who made the trip in the opposite direction (American who moved to Germany at 24), you totally should. I meant to spend 2-3 years skiing, seeing castles and drinking tasty beer, but met a nice German guy a year into it, and am now 40 and expecting our first kid.

About that: I’m delighted to still be living in Germany and to be with my husband, but had my American-centric brain fully taken in that he had no interest in living in the US despite having enjoyed his master’s program at Wisconsin, I possibly wouldn’t have gotten seriously involved with him.

Make sure anyone you date more than casually understands your true level of interest in remaining in the US long-term, and earlier in the relationship than you’d think it would make sense.

Financial: your worldwide investments may be taxable while you’re a US resident, and the way non-US mutual funds are taxed is a nightmare. If you have any, you may want to look into selling them before moving. You will then want to consider selling your US-based funds before moving back, depending on how your home country taxes them. Ask a tax advisor based in the country you’re moving to for advice, though.
Nice to see Uber rediscovering domain-driven design principles.
I have added chat support now. Thanks for the quick suggestion
It creates a catch-22-enhanced version of Who’s On First[1][2], except it’s Who Has Legal Standing? It results in judges being hesitant to rule as they ought due to intentional muddying of the jurisdictional hierarchy of bureaucracy and who is able to claim standing and harm. It’s a shell game designed to disempower everyone in the courtroom to the boon of those who can never or will never be brought inside one.

What if change through the courts is impossible because it would take longer than any one person’s life to acquire standing to sue, and have the case heard?

I messed around with the settings in HN the other day and managed to enable the procrastination settings. Was locked out for a couple hours....

That’s what I get for just toggling things. It’s been a habit since I was a child, if we visited a house or rented a car I would flip any switch or touch any button or knob I could reach.
Aggressively non-comformist comments also potentially result in a ban, especially when it comes to sensitive topics. The negatives outweigh the positives in many cases. Discussions here on scientific topics like human group differences border on outright delusional because there is no polite way of questioning the dogma.

Have you considered the case that you find the discussion delightful because it is just reinforcing your biases?
This is a fair point.

What I intended to mean was not that we should not regulate against it, but that regulation will be ineffective.
That's true, though they didn't simply have people dance. They had people learn different dance coreograhies and perform them.
What about the family of the user? What about friends and relatives affected by a user's addiction?

> Oh it wasn't unusual. It was intentional.

I know that perfectly well, hence the scare quotes. I was referencing the term used by the person I replied to in order the draw a parallel between the two.
This feels like common sense to me.

The dance they describe isn't just physical movement, it's also staying within a group movement which requires both reading where "the group" is and giving space to individual differences.

Obviously the focus here is on exercise but I would be curious if a less physically demanding but similarly grouped activity would have similar effects on brain function. I suspect that linking physicality and social coordination is key. We are both brains and bodies and neglecting either is unhealthy in the long term.

I used to have script that would gradually dim my display unless I typed.

The broader issue for me isn’t a particular website. It’s brain-dead consumption of feeds. Typing guarantees that you’re thinking a little.

Even with email, it made me less likely to overthink things. It gave a bias to action. Keep moving, keep typing.

I had a whitelist of exceptions (IntelliJ, Terminal, etc).

Unfortunately the script broke a few years ago. I keep on meaning to fix it but I’ve been too busy reading feeds.
I meant on a national scale.
You don't give someone a life sentence to rehabilitate them. At some point, you have to recognize that certain people are dangers to society and need to be "incapacitated" from causing further harm.
So long as you're not knocking your noggin around. Any contact sport involving blows to the head (even padded blows) is probably more detrimental than any benefit gained.
Those protests in the US have nothing to do with justice. They are about power.

People playing around with radioactive stuff, even if they are well-intentioned, can easily mess up and contaminate themselves and others with it. Radioactivity is not detectable to any of our senses, only radiation poisoning is. Things are completely different with LSD and other drugs. You could argue that making meth is a dangerous activity in itself, but a properly regulated industry could evaporate any real need to home-brew large amounts.

This one is probably both.

I don't disagree with him about the need for advanced societies to protect free inquiry and independent thinking.

But the psychological taxonomy expounded here is simplistic and all the little things he attaches to it, like the psychoanalysis of tattletales, are probably not well supported by much evidence.
Maybe have them shine on to a neutral surface with some distance.
Thanks for your perspective. My understanding is that through an internal transfer visa it's feasible to receive a Green Card, especially as an EU citizen. I'm actually eyeing NYC, just because I'm really intrigued by the perceived diversity and culture, and it being the cultural epicenter of the Western world. May I ask which place you chose?

It's tricky for an officer to know if an order is legal or not, hence the issues. What an chief of staff is sure of is that a legal order can only come from the president, and at 12:01p on Jan 20th the president will be whoever the joint session of congress says it is.
I find Dart comparable or maybe even slightly better than Kotlin, not sure why exactly, some things I like:

- Overall the language is simpler and more regular, it's easier to read it.

- Async / await is way simpler and less mentally taxing than Kotlin's coroutines.

I do think your point that the physical repetitiveness isn't the only factor is correct, however I believe it is the main driver.

Almost all physically repetitive exercises combine sensory and cognitive tasks to varying extents.

I would also argue that learning and implementing new movements is a much more diverse task cognitively than getting better at beatsabre.
I was suspicious of the effectiveness of contact tracing apps, which have to rely on something as unreliable as Bluetooth to estimate distance across different kinds of hardware, different kinds of software drivers and in different situations. That got worse with some governments wanting to collect location information through the contact tracing apps 24/7 and centralize it.

> It would appear that no government has thought this out properly yet.

This seems to be true at least in India, where the app is a centralized one that doesn’t use the Apple/Google framework The app tracks the location of users at all times (it asks for that permission) and hence cannot use the APIs since Apple and Google prohibit such apps from collecting location information. Since it requires background location access and Internet connectivity, it’s a good addition to drain batteries quicker.

The government also famously declared that the app would be open sourced so that it could be improved and issues fixed. That turned out to be a farce with the source released only for the Android version, and that too for an older version of the app with some code removed (the code on the Play Store was newer). They stopped releasing updates of the source. They didn’t release the source of the iOS app, which was supposed to be “shortly” (that was around two months ago). They didn’t fix the issues that people raised on GitHub. Yet the government claimed that the app was effective and put out some numbers on it being useful (without any backing data or any way to verify those claims).

It gets even worse. The app being a platform for contact tracing is only one facet. The goal that wasn’t widely disclosed was to have private companies build on top of the app and its server side data to create platforms on health data collected from hundreds of millions of people. Note that India doesn’t have a data privacy or data protection law, leave alone anything to control health related data in the hands of crony capitalists and opportunists.

Now all talk about contact tracing and its effectiveness is muted or nowhere to be seen, though the app is being pushed as a requirement to give people permission to travel and for other purposes.

The platform has become, and is continuing to become, what some people feared...and that’s getting farther from handling COVID-19 or a public health crisis.
Can confirm -- writing data to memory is incredibly fast. It's faster to use a lock-free queue and use CAS to insert data though:

I do believe that VR absolutely has potential to shake this up. VR games have a physicality to them that is unmatched in any other sort of computer game.

I played ping pong on VR the other day, and it was amazing! I've played a bunch of ping pong in real life, and the physics in VR - along with the feedback in the controller - felt almost exactly life-like. It was truly a mind-blowing experience. It made me realize though that we're really at the tip of the iceberg in terms of what kinds of things we could do with VR. Up until now, the games we could play had the limit of only taking a few key presses and mouse motion as input. Suddenly we're now afforded the entire realm of physical motion. Not to hype it up too much, but the possibilities feel practically endless.
> However, by now interest rates have been near zero and well below inflation for the entire adult lives of anyone under ~35

When were interest rates on bank accounts not below inflation? Bank interest failing to even keep up with inflation is not a recent phenomenon; as far as I'm aware, our low rates now are better, inflation-adjusted, than the old high rates were.
Incapacitation makes sense, no? Would we not want to incapacitate a serial killer's ability to serially kill? If we really believe crime is bad then we should want to incapacitate people from committing crimes.

I don’t want to “shame” anybody in particular, but look up your local charter airlines and what they offer...

This can of course vary if there are rather complex requirements (e.g., a certain type rating, experience level etc.) - but being a pilot isn’t cool financially anymore. A small fraction ends up with “the large airlines” - but if you don’t, you are not in for the big money...
Amazon definitely keeps metrics.

There was a point where I had a string of returns that bumped my overall return rate up above 30%.

Though after reading up on it, I still don't like it much. It makes the web behave in ways I don't expect it to and I don't really see why anyone would really need this, unless they want to fundamentally change the way the web is expected to work.
"take advantage of the rise in unemployment by trying to lock in highly skilled workers at a low salary"

>> By 'take advantage' do you mean offering jobs to people who might be interested in accepting them?

>> By 'lock in' do you mean employing people until whenever those people feel like moving on to something else?

If so, those are strange definitions. Doesn't sound like anybody is being forced into anything.

I have no idea why so many countries think it's normal for their community police to carry something so extreme as firearms. Really boggles my mind. They should be reserved for extreme emergency situations, used by very specialist officers. There should be absolutely no need for an officer responding to routine tasks to be carrying military-grade weapons.
Why accountants are still a thing?
For the past 40 years, accounting software remained more or less the same, even though that everyone within the industry knows for a fact that one day Ai will take a big chunk of the industry, no one yet has taken it on themselves to bring this change.

Some say;
But.....it is too early, Ai is still new & not that sophisticated.
Yet Ai will be driving cars soon

Others say;
Quickbooks or another leader in the industry will be the one to do it.....
Yet we all know that innovation rarely comes from within, and just like the innovation in smartphones, an outsider usually is the one to do it.

We have taken it on ourselves to bring that change, starting with micro partnerships, for them, we are building an Ai Accountant that can replace a full-time accountant, for a small fee of $47 per month.

Top Quotes on Artificial Intelligence
How about gymnastics?
This comparison assumes that the issues with the org are known or self evident. In many cases such as crappy products, the reasons will be evident for buyers (though just choosing not to buy doesn't help future buyers from experiencing the same problems as you; that's why voting via reviews is so important). But even in consumer goods, voting with your feet/wallet falls through when the discussion is no longer specifically about a marketed service or product. If you are getting screwed and don't raise a stink about bad customer service, for example, nothing will get done about it, and many people will likely have to re-live your experience unnecessarily. So I disagree that vote with your feet/wallet is a good strategy here.
I wonder if the same effect is even stronger for many competitive sports, where the brain-muscle loop includes a more complex modeling of competing agents vs cooperative ones as in dance. Something like basketball is anti-inductive; falling into an easy pattern will be immediately exploited by the other team in a way that isn't prevented in dance.

Fibromyalgia is a garbage bin diagnosis
I can definitely see this. I have very mild Cerebral Palsy. I can run and end up in the middle of the pack in most races and sometimes in the top 3 or four for my age group (pre-Covid). I even taught fitness classes about a decade ago.

But trying to learn a dance move or take someone else’s choreography heavy exercise class was like trying to understand a second language when you are first learning it. I had to translate it to my “native language” and it took much longer for it to click even when I could physically do it.

It was more mentally taxing than studying for any test or anything I had to do as a developer.
US unveils blueprint for 'virtually unhackable' internet
That's great to hear. I've lived in three different countries in Europe and spent a year in the US as a visiting student. Like you, I really enjoy seeing how other places operate. My main motivation for moving to the US are the career perspectives; while there are great companies in Europe, too, the breadth of the US job market in tech is unmatched. In addition, I really enjoyed the American culture during my time there. That said, every exchange student I have ever met fell in love with the country they visited, so it's likely that I am biased.

> Also be careful around compilers and interpreters. No mainstream language specifies how to make constant time code, so your tools could insert secret dependent branches where the source code had none. High level languages in particular tend to have variable time arithmetic. In practice, low level languages like C are fairly reasonable, but I've seen exceptions.

This is by definition not simple if the very tools you're using can cause what you think is correct to be wrong and dangerous!
You can do this with Pihole blacklist, which not only apply this to your current machine, but your whole network.
Absolutely agree. Before everything shut down I used to practice yoga at a school here in Brooklyn that was very physically demanding and attracted a lot of more advanced practitioners. Most of the advanced students had long histories with dance or martial arts (or both). All of these arts teach increased awareness both physically and mentally, challenges your proprioception, and surprises the body with creative movement.

I personally had been looking for a place to practice a martial art to add to my yoga practice, but then covid hit and the city shut down. Hopefully after all this is over though.

Mortgages might be a poor example because of prepayment penalties, the ability for a lender to choose to apply an excess payment to future interest payments instead of the current principal, and all sorts of things (each situation is different, you just need to do the math).

Something like a credit card or student loan in places where those are common might be better targets. They usually have ordinary compounding interest, and the delta in your net worth (assuming no other effects like taxes) between investing P dollars at an interest rate R for time T is identical to paying off P dollars of a debt at an interest rate R and waiting till time T has elapsed.
