Ask HN: Are there *effective* games that teach kids to program?
There are many options out there, with mixed reviews.

For very young children, pre-programming just means learning logic, and about the world. It could be argued you might learn that just by going to the park.

But are there games that actually accelerate learning of mathematical concepts like Boolean logic, probability, conditionals and loops?
I was going to say the same thing

Anyone who's worked 80+ hours/week can tell you that work is an efficiency function. At hour 75, one's capable of much less (cognitively and physically) and more prone to mistake than at hour 5 (as the article notes). The stakes are high when it's overworked 20-somethings working on an expensive lawsuit or transactional spreadsheets or trying to ship code on a deadline, to say nothing of engineers and others involved with public safety.

The notion of more work = better isn't as straightforward as you make it. The article itself points out Chernobyl and Challenger as the result of pushing people. Even from a purely competitive, capitalistic POV, pushing people to work more has very real risks; risks that make the expected return negative the harder one pushes.

It is entirely possible that capping the number of hours worked – such that workers are rotated and therefore are always fresh/at their most efficient – is more optimal than driving them harder and harder in the name of competition.

We see this with Olympic/professional athletes whose coaches enforce mandatory rest days and optimal sleep. Certainly these athletes, if they just "worked harder" in the name of competition, would be harming themselves after a point despite putting in more hours.

This recovery period, while mostly physical in nature, also extends into the cognitive realm as well. Knowledge workers need recovery too.
What about new router? And yes NG2 much better than NG1, I agree with you.

Your proposal is comparable to saying that checks and balances are not needed in a democracy, politicians just need to govern "right".
This is about incentivising scientists to do the right thing instead of merely demanding it, like you do.
Refusing to socialize with your friends will cost you your friends. It's true that some people socialize by going out to bars and what not. If you don't wish to do that, you can arrange cheaper alternative.

1. BBQ (Go to a good meat market, for $30 bucks, you could get enough meat (chicken and burger) to feed 8 people. If your friends chip in, bring a few drinks, it would cost everyone less than $10.

2. Netflix/Movies@Home (Have everyone come over, make popcorn, drink cheap beer, watch a great movie)

3. Games (board, card, video game)

4. Activities (sports, hike, museum, art fair, food fest, local city music festivals)

There are tons of ways to socialize with friends for free or the cheap. Sure, some might not be into that, then so be it, you can make new ones and retain the ones that are into it.
Which one allows to import multiple versions of a lib/module/package with different versions? (Not primarily but also an issue of the package manager.)
Why not just give it a try on your own? Do it for 21 days and don't let yourself have an opinion on it until that stretch of time is done. Then see how you feel and make a decision.
Totally agree. I started "programming" at an early age which just made me feel like I didn't need to pay attention when I took actual CS classes. The results were that I missed out on learning a lot of lessons the easy way (in school) and had to learn them the hard way.
I think you're forgetting to take into account the effect of longer hours on productivity (negative), and the fact that our working hours are a choice which (within a certain range) don't seem to have a strong effect on actual results in the "marketplace".

In the developed world, the 40-hour week is standard both because 60-hour weeks are less-productive, and because as a society we've chosen to prioritize health and happiness over the (mostly imagined) productivity of a longer workweek. But 40 isn't a magical number, it's possible 30 would work just as well or better.

Satire aside, couldn't they just revert the commits? That is the whole point of the system. ONLY if the system didn't work would Tom be angry, but IF the system didn't work then the rest of the story is contradictory.
I think what you are describing is boot-strapping your peers. This is often the case when there is a mix of advanced-beginners and total neophytes. Like one student explaining IDE configuration, or how to debug a problem by looking at log files. The teacher in this case often learns as much as the student.
The FI half of FIRE is generally not about retirement. (RE = retire early) but rather getting to a point where you have enough money that you don't need to go work a 40-60 hour a week job. Maybe you could retire but choose not to, and instead take long periods of time off and/or work something part time while pursuing other interests.

FI means different things to different people, but generally just means you have some FU money.
Yet these retail stores are comprised of basically all part-time employees outside of management. My guess is that the money they save on benefits is worth it. Plus it doesn't seem like they need more people to manage the part time employees.

With GPS having at best three metres accuracy?

Regular unaugmented GPS actually has something like 10m-3m of error. GNSS augmentation, like WAAS, gets you down to 1m. RTK GNSS gets you down to 1cm, but you need a stationary base station, and accuracy gets worse the farther away from the station you are. A REACH RTK pair costs $570: https://emlid.com/shop/reach-rtk-kit/

You can get down to 1mm of error with good antennas and long-term averaging-- no good for moving objects. This is how we measure continental drift.
I am super-impressed that someone from B&H found my comment, made an HN account, and replied to it directly.
It does. This is how e.g. digital economy works, and nothing could be done about that. In traditional economy, there can be e.g. a bakery shop in nearly every corner; people will just choose the closest one in most cases. In digital economy, all locality barriers are erased, if you need search, you go to Google, period. No need to evaluate other options as long as Google works OK. No legislation can change that (and if it could, it would bring much more problems than that).
One would really hope the steering in self driving cars is derived from sensory input and not nav system waypoints.
OK, how about: HTC's case is an order of magnitude worse? They're no Sony and not even Nokia.
The headline is completely wrong.

From the article: "Over the past two years, 18 cities have reported how many bookstores they have, and 20 have reported on their public libraries."

It's not "the most book stores and libraries per capita", it's just the numbers each city sent them.

With Amazon and eBooks, I don't know if counting bookstores really matters.
Any change will be in the tools, not the language. The compatibility promise explicitly states that the tools can change (https://golang.org/doc/go1compat#tools).

Count. Count each breath as you do it. When you get to ten, start at one. If you feel your mind wander, start your count at 1 again.
The big difference is that artillery shells are a lot more powerful than land mines, and some of those shells have mustard gas. Using a machine of some sort is a good idea but I bet it wouldn't work the same as the minefield sweeper at all.
Or one can separate white space diffs from functional diffs and reduce the dependency on particular tooling choices. This often works a lot better because style diffs often reflow lines that -w doesn't handle.

Add to that the impossibility to publish negative studies. Science really needs to get its shit straight.
Your mind is supposed to wander. That's what it does.

The key is to not beat yourself up about not being "good" at meditation. When you realize your mind has been wandering, take note of it, return your focus to your breath, and move on.

Though, if you can ONLY explain it to a six year old, then you still probably don't understand it yourself.
And also we need to start publishing negative studies way more.
I'm trying to get myself to enjoy gaming again. I can't seem to just relax and play a game without thinking I'm wasting my time. It's also hard to get the same high in a game that I do when I solve a bug or add a feature to whatever project I'm working on.
This looks awesome. Latency in touch/gesture systems is brutal though.
Resolution strategies are really interesting in Nix; specifically, because it doesn't have any! All dependencies, etc. are passed in explicitly (either as function arguments, or by importing files).
>Starting today, if the powerful wanted to, they could design a rational system that maximizes happiness and minimizes suffering for the largest number of people possible.

In the same breath you pointed out why such a system does not work then state such a system is possible, I don't think anyone with power would ever genuinely want to enact such a system, but even if they did those participating in such a system would always look for ways to un-level the playing field and recreate the hierarchy we seek in society as primates.

Troll! No bigotry hear. You made me angry. I have a technical problem with this. It seems that this movement to recognize gay rights is being done too forcefully, too artificially, too weakly. There is a more graceful approach to this, but we are not making an effort to do it this way, either due to haste or due to fervor.

You are right. I don't know a single thing about Milk other than what the article glosses over. And it is not fair to Milk, but I am not making an extra effort here, because I am not vested in this. I was hoping the other HNers would elaborate on who he was, and counter me.

When things are done rashly, we weaken the entire entity this way. In this case, it was the honor of immortality via a ship, being given too hastily away for political reasons.

The author mentions the CMU acquisition. I think their contention is that it's not enough, because Uber doesn't have access to the kinds of vehicle telemetry data its competitors do that would be necessary to train good self-driving car models. Google, and other companies with existing advanced vehicles on the road, have thousands of cars in the wild now with suits of sensors collecting telemetry and phoning home. Uber contracts drivers who drive their own cars, so it's not benefiting in a vehicle-telemetry sense from the drives it's arranging in the way it could be and its competitors do.

I think this is probably a solvable problem, though.
I don't understand the hype behind vim. The biggest productivity boost I find is having an editor which has great code completion and error squigglys as soon as you cause an error.
DON'T USE GPS ALONE FOR SELF DRIVING CARS.

Not even DGPS. Really. Don't. A ton of metal moving under its own volition really needs to be looking at the things around it, directly, using some kind of vison. Cameras are good.
Hah, it was a response to my comment back then too.

Either that applies only to multiboot v2 or there was a bug in qemu loader since I had a non-zero value in .bss.
As long as the productivity stays the same or increased, this option is viable. But if not, it isn't. Increased productivity from shorter hours is good, of course, but Keynes thought that even decreased productivity could be fine, as at some point it will be "enough".

Here's the catch: under competitive market economy, there is never "enough". And if you pass on market economy in your country, there are other countries who will outcompete you, both economically and militarily.

Good call. I'm curious, what is your solution to getting more sleep? Frequently those all-nighters come as a result of deadlines and pressure from work. The usual tradeoff is work vs family vs sleep, where often you only get to pick 1. Have you had any success in getting 2 or even 3 of those together?

I think they meant to say (or should have said) that SDCs need more locational precision than GPS provides.

I was going to justify their phrasing as being easier to understand, and accurate enough for a lay audience, but ... mine is still better, IMHO. I would have said:

"Self-driving cars, for example, need more precision than GPS has to avoid accidents."

I think if you're looking for the meaning of life, religions are easily worth the research.

I think the reality is that religion is looked down upon because it's "old" and existed before modern scientific methods existed. Nevertheless, it still provides some of the most consistent answers to the meaning of life that we have available, and they've been trusted, followed, and researched for far longer than any of the other ideas.
Somewhat darkly--is any of the software we write going to still be useful in 80 years?

Terrible devices with awful intent, but they do still work.
Which is why most professions are settled on 40-hour work week, as the ideal way to extract long-term productivity. If other time arrangements will give more productivity, employers will be eager to adopt it. But it is not the case for e.g. 15 hour work week.

vendoring is a solution to the problem of reproducability, not the problem of distribution. Vendoring particularly for application code should be at least an optional part of whatever solution is chosen by the go team. Vendoring is not the only solution in this space, at $work we mirror any third party repository we use.

However, vendoring doesn't solve the problem of getting a library that I have reasonable guarantees will work with the rest of the ecosystem. You can use vendoring in libraries but you can only use their types internally in your apis, if you put them on the boundaries you will run into compatibility issues.

my doctor friends believe that eating less is the secret to increasing life span

I've heard this before and it makes some sense. Don't know how to reconcile it against my desire to get out of the 17-18 BMI pit I've been in, and put on some healthy muscle (which requires a lot of food).
Resonates with me, especially the importance of sleep. I was very pleased to see on TV here in Costa Rica the other day an advertisement on mental health awareness that explicitly tells people to get their 8 hours!

Diet and exercise have also been things I've been learning very belatedly to take seriously.

I'm currently trying to improve at listening, communicating, and reading instructions properly.
I do care, I'd like to know about surveillance (whether I can do something about it is secondary). Knowing may allow me to modify my behavior.

To your point about reasonable expectation of privacy. On the surface, yes, you do not have a reasonable expectation of privacy in public, however, I do not like the idea of having my picture tied to identifying information like a mac address. It starts to provide a fuller picture of a person and would allow more data in which to build up a profile.

At the end of the day I'd like to choose how and when my personal information is exposed (to the extent that I'm realistically able to control it)
If an alternative is not named, does that change the value of the opinion in any way?
There is a philosophical assumption underpining astronomy and cosmology, the so-called "cosmological principle."[0] This is an assumption (albeit not completely unfalsifiable) that physics across the universe at large scales is the same for all observers, that here on earth there should be similar to physics in andromeda. Of course, all scientific experiments done have been done on or near earth, and thus, our interpretation of astronomy on earth is tempered by experiments we do here, for example, we assume that the speed of light here is the same as the speed of light elsewhere.

This is, in principle, a problem. We unfortunately have no way to measure the speed of light in andromeda, unlike what we can here on earth, so we really have no idea if our astronomical models are wrong given the non-constancy of the speed of light in andromeda or elsewhere.

So, yes, in principle not being able to repeat science experiments everywhere in the universe is a problem. However, I think if one thinks a little less broadly, testing newtonian gravity in say, Italy and also in China shows at least across the Earth, the phenomenon is similar. Then, at least one can say, "certainly, gravity is the same in Italy and China, and perhaps across the surface of the Earth." That is a stronger statement than "gravity is this way in Italy." Ordering claims by "scientific goodness", we can say that

Gravity is the same *across the universe* > gravity is the same across the Earth
> gravity is in Italy

My point here is that even if one can't fulfill the extreme of testing theories everywhere in the universe, one can progressively prove stronger and stronger statements regarding the validity of scientific theories.

Somewhere the LHC stands between "the SM is validated across the universe" and "the SM is validated at one detector at the LHC". Yes, it would be "better" if the Higgs was found at other experiments, but the current situation is "better" than if the Higgs was found at one detector there and not in any other. Repeatability, like everything in science, is not a binary step function but is some continuous function over the domain [0,1].

The biggest impact individual developers can make on all the points I raised is to keep their own copyrights on copylefted works and do not sign an employment contract unless it explicitly allows you do to that.

Developers have more leverage in employment negotiation than they realize. Right now, most copylefted codebases that have historically had mostly individuals holding the copyrights are drifting to having companies mostly hold the copyrights. We have to stop this trend.

If individual developers hold copyrights, they make their own decisions about enforcing, and companies who oppose enforcement have less leverage.

Herodotus's Histories is probably the best place to start. Maybe 50% of it is accurate, as it was common among historians of the day to create functional exchanges of historical figures to simulate the debate of ideas, such as the Persian Magi debating on the kind of government Persia ought to have, between aristocracy, democracy, and autocracy.

Also, and while it is very very modern, John Green's Crash Course World History (and US history) is a great place to start so you have context when you delve deeper.

Voluntary agreements, legal settlements, and damages awards are not equivalent to taxes. For example, if I were to set your car on fire, and you sued me for that tort, any payment I made to you would be compensation, not a tax.

In addition, social contract theory is wrong, and I don't believe in it.[1]

Pollution may be grounds for a lawsuit, or it may not, it depends on the circumstances, just like any other tort or trespass.
