Ask HN: how you increase cognitive load of an activity
A bunch of pop psychology articles led me to a strange solution to an issue.

I was listening to an audiobook while relaxing in my bedroom, but my mind kept wandering.

I don't have this problem during summer because I'm usually hiking outdoors while listening to audiobooks. But it's too cold to hike now.

The solution was to increase my cognitive load. I started tossing and catching a ball, alternating hands. My focus instantly improved. It was easier to listen to the audiobook.

In case anyone else on here has experienced this "Lifehack", please share simple ways you've discovered to increase cognitive load to improve your control over your attention.

* for those who are interested, the pop psychology articles referenced earlier had to do with the "increase challenge" part of Mihaly's "Flow".

Zip disks were much more popular. I worked as a computer hardware technician in an independent computer shop in the late 90s, and while I'd heard of the LS-* drives, Zip drives were the only ones I'd worked with. We had an external one on the work bench.

CD writers were available at the time, but typically you'd use a CD-R not CD-RW owing to expense, and it was something you'd need to do exclusively, as in not use the computer for anything else. If the machine was too busy multitasking, you'd get a buffer underrun, which would turn the CD-R into a coaster. Zip disks and equivalent were more like floppies in this respect.
I am going to be obtuse and say that since Bayes theorem is a non controversial rule about conditional probability, if you interpret your NN as a probability distribution over outputs that is updated by data, it is always able to be interpreted as "Bayesian" and can be a helpful way to examine what your implict priors are (i.e. via architecture or regularization terms) to see if they are reasonable for the problem at hand. It is no surprise that weak uninformative priors are sort of useless. Explicit priors shine when you know something about the actual problem (say some moments or some invariances in the problem set up).
Tesla is hoping for their cars to last a million miles. The electric motors should already be able to do that. If they can continue with not changing the complete car every 5 years, like most other car manufacturers do (to make older versions look dated and drive sales of new cars), you might be able to figure out everything that breaks before a million miles and fix them. This would be a real improvement on the amount of pollution/mile that comes from manufacture of a car.

I have to have insurance now, even though a lot of the functions of my car are controlled by their software.

Remember when the Toyota had that problem of the accelerator "getting stuck" because the software didn't disengage? Initially the owners' insurances were paying out, until it happened enough that they were able to prove it was Toyota's fault, and then Toyota had to pay them back.

I imagine in a self driving world it would work the same way. You get insurance, the car has a crash, your insurance and the manufacturer fight out whose fault it is.

For me it makes lots of sense, it is not "nonsense".

Java is a gigantic dependency. Any project that depends on it adds all this dependency with it. In many cases this dependency could be bad or toxic for the project.

It depends of what you do for a living. Personally I will never let anyone include java as a dependency in my company's projects, because for what we do, java is slow and linked to Oracle.

I started by typing in listings from a book (101 Basic Games). Then I'd start modifying the games. Then I'd write my own. It's how people learn.

> I originally switched because some years ago, Chrome was being a memory hog, and I remembered using Seamonkey years before that.

Same for me a loooong time ago, when I found out that running Seamonkey Web browser and e-mail client together used less memory than either of Firefox or Thunderbird alone.

After a few years I stopped using it for e-mail, because I had troubles with several specific versions crashing too often, and having all one's eggs in the same basket is not a good idea when one of the eggs rots the others (i.e. a browser crash killing the e-mail client and vice-versa).

My parents are still using it for both Web and email, one on Linux, the other on Windows. It is more stable these days.

Exactly. Rules must always be enforced by some higher authority. Because the highest functional units of governance are nations, this means that there will always have to be some "most powerful" nation enforcing order.
Clojure is pretty much a one man job as well. I'd say its more because Lux is still an incomplete language, it isn't ready to catch on yet, since its still beta. But if it reached maturity it could.

You could help contribute to it and accelerate that process and its adoption?

I'm also not sure of your analogy, Lux says on its readme that its syntax and overall look and feel was inspired by Clojure. The fact it's implemented in Clojure is just showing Lux is a much newer language, give it some time.

> There's no such thing as a rules-based, open world.

You're living in one right now. Anarchy need not be synonymous with chaos, especially if disputes and conflicts are relatively unimportant (due to easy defense making 'rights' self-enforcing). The point of courts is then to arbitrate disputes in a publicly-visible way, enforcement is relatively less important.
Should be Stone-Wierstrauss, and it is true on compact regions only(and requires a few other bits).
There are both "residential" and "commuter" colleges. For instance in my locale, the Big Ten university is mostly residential for undergrads (served by large student rental neighborhoods), and the housing typically chosen by grad students has decent access to the bus service, or bike-friendly routes.

There's also a community college that serves a lot of commuting students, and has none of its own housing.

The regional colleges have more commuter students, since you can save a boatload of money by living at home, but also probably don't have such severe parking problems -- land is cheaper.
With the click-of-death problem getting so much attention back then, branding their product Click may have been going a bridge too far.
Moving to a high carbon atmosphere COULD be a good thing. You’re right!

But in nature there is a concept of a “disturbance”. This is a hole that opens up in an ecosystem, caused by fire, famine, violence, etc. These disturbances are a necessary part of the succession of species, which itself is an important part of ecosystem health.

HOWEVER, you can’t ignore the dimension of time. There is a FREQUENCY of disturbances which becomes destructive. Too many disturbances in too short a time results in the ecosystem being set back in time, hundreds, thousands, or even millions of years.

That’s the danger of climate change. Not that it happens, but that it happens too fast for ecologies to survive.

YouTube’s corporate news obsession VS Pollen
That isn't true. There were car navigation devices that predated non-military GPS. They used inertial sensors to understand the car's acceleration and turning, and used on-board maps to correct for the inevitable drift. The car made a 90 degree turn onto a side street but the map indicated that road was 30 feet ahead, it would reset its position to be 30 feet from where it thought it was.
Yes this seems more like an attempt to capitalize on a negative trend (legacies no longer applying and matriculating) to achieve positive brand association (Hopkins is now leading the way towards a meritocratic future). I'd be curious what led to the fall in legacy students in the first place.
The only reason courts have authority to arbitrate disputes is because they are backed up by the will and authority of the government, which in turn has a monopoly on the use of force in society.

I think the game Quoridor has simple rules but is very deep. It's a 9x9 grid of cells where one places length-2 walls between the cells to inhibit movement (the goal is to get your piece to the opposite side of the board).

On your turn you can either move your piece, or place a wall. You have 10 walls to place.

The one non-obvious rule that completely changes the strategy of the game is that you cannot make it impossible for the other player to win (you can't simply box them in).

So a common theme is to try to maximize the amount of paths your opponent has while minimizing the number of paths you have, so that whenever your opponent commits to a path, you block it and force them to backtrack.

But say your opponent has 2 paths, and they begin to commit to one. You are waiting for them to commit further so you can block it and force them to backtrack. But before you do it, they block the other path themselves. Now it is illegal for you to block their only remaining path.

On the face of it, the branching factor is much higher than chess. On each turn one has 100+ possible moves. I have written pretty highly optimized minimax AB-pruning type AIs for it and have never managed to make an AI that can search deeper than 7 moves or so in a reasonable amount of time, and my AI was the strongest (by far) of any I could find online (and better than any human player in my friend group).

It's pretty computationally difficult due to the "cannot make it impossible to win" rule. If you do it naively, that involves an A-star search for each possible move. You'll max out around 4 moves deep with that strategy. A few observations will get you a bit higher. e.g. A wall cannot possibly block a path unless both ends of the wall touch another wall (or edge of board).

There might be some sophisticated graph cutting algorithms I am not aware of that could make this tractable, but I haven't found any that mapped too well onto the problem.

I think Quoridor is actually really ripe for an AlphaZero type approach (due to the high branching factor and expensive compute needed to determine move legality), and I would love to see a superhuman game played.

You can play against someone's javascript AI here: https://danielborowski.github.io/site/quoridor-ai/display.ht...

I think this AI does a depth 2 or 3 search.

Law of Attraction
> single men's expectations of potential partners are totally the prime suspect here.

It's both genders; women do not lack agency in the dating market. It'd be as fair to make "my partner should be willing to give up their career to start a family" as the default and blame the dynamic on women - after all, they prefer men who are unwilling to compromise in the pursuit of their career.

I try to avoid either, and just mention that this axis has a gendered component in terms of both what people do and desire.
Harvard and the Ivies have been doing what they do for centuries and they're still successful. I'd suggest they know what they are doing when they let in privileged kids. If I could get into an Ivy I'd probably like to have some "thick" privileged kids in my class too to help fund my startup.

> Not sure this is how you meant it. If you mean to say that rights come from governments that is not quite correct, at least not in the US.

I'm not a bitcoin person, but...

I don't think you can mine $0.01 worth of bitcoin. Most of the time, you'll lose the race to find the correct hash collision and so you'll end up with nothing. Other times, you'll win and get the reward for the block which is 12.5 BTC at the moment (IIRC). People do join collectives to pool their mining power, but there isn't predictability to when the collective will end up with a coin. If you're looking to set up a web server, you don't want to be waiting days or weeks or whatever while your collective tries to win a block. Theoretically, you could buy a lot of computing power and always get unlucky.

So you can't really get a penny of bitcoin via mining.

Well so far we do not know, so again this is just speculation. Your guess might be as good as mine. There does not seem to be any serious scientific results in this direction, other than nonsense like the Drake equation.

I think the variety among the possibilities for other intelligent species (if any) would far outweigh the number of them. Hence it might be probable that there would exist two similar ones, but it would be very improbable that any of them would be similar to humans.

The point about "communicating" with a piece of rock was exactly that we cannot communicate them. Even if we would run into an alien species (which seems unlikely), it seems very improbable that any meaningful communication could happen.
> I can't remember a single alien movie with sea creatures or intelligent birds. But if anyone knows some, please let me know :)

While not exactly movie and not specifically sea creatures/birds, there are plenty of anime series and visual novels with intelligent non-humanoid alien species. Parasite from Parasyte, some forms of BETA from Muv-luv, aliens from Stellvia, (NSFW to Google) Saya from Saya no Uta (real form). Dragons are also often portrayed as intelligent race originating from space (e.g. Final Fantasy XIV & Kumo Desu ga, Nani ka?). Many of these usually have a way to appear as humanoid to make conversing with mankind easier though (and likely to make it easier for readers/watchers to relate).
