My school, Purdue, offers a program (Income share agreement - ISA) where a borrower pledges a percentage of their future income for 10 years in exchange for tuition money. To me, the most "innovative" part of the program is that the percentage charged varies by major.

The main conclusion from this program is that if you're income is going to be high (basically >=$70k/year starting salary), you're better off with a traditional loan.

Ammonia is gaseous under normal conditions, meaning that any leak would result in presence of gaseous ammonia in air. 500 mg of ammonia per m3 of air can damages eyes, a short exposure to 3g can have overall toxic effects, at 7 g and higher it damages the skin. Gasoline, hydrogen, or monoxide don't come close to this level of toxicity.
For language learning, consider Pimsleur, who discovered ‘the algo’ previously:

“Graduated Interval Recall - Dr. Pimsleur’s research on memory was perhaps one of his most revolutionary achievements. He discovered that if learners were reminded of new words at gradually increasing intervals, each time they would remember longer than the time before. He documented the optimal spacing for information to move from short-term into long-term, or permanent, memory. This theory is at the base of all the Pimsleur programs.”

It's an article from Wired _MAGAZINE_.

What do you expect? A terse jargon-filled exposition of the algorithm fit for graduate students?

It's perfectly fine to not appreciate the style of the author, but to call it "bait and switch" is a bit much.
`await` is useful since with the absence of it you can schedule multiple tasks concurrently. In JS:

var task1 = someAsyncTask1()
var task2 = someAsyncTask2()

await Promise.all([task1, task2])

If `await` was implicit then task2 would wait for task1 to finish.

That isn't the claim. The claim is that a bunch of cookies are specifically exempt from the law and the law tells you that you don't need to put up cookie banner click-throughs. And also that everyone ignores that, and puts up the banner click-throughs anyway and then moans about EU law.

Intramolecular bonds are quite a bit smaller than intermolecular distances, so if you pack atoms into longer molecules you get a denser result.

I'm guessing very long molecules become problematic (because they don't pack well), but ammonia is a small molecule so way below that.

Liquid ammonia has a density of ~690 kg/m3 and a molar mass of 17 g/mol so ~40k mol / m3, as NH3 that's ~120k atoms of hydrogen per cubic meter. Meanwhile liquid hydrogen has a density of 71g/L and a molar mass of 2.02 g/mol so a very similar ~35k mol/m3 but as H2 that's only ~70k atoms of hydrogen per cubic meter.

And liquid hydrogen aside from being extremely flammable, can't exist above 30K and degrades storage material (https://en.wikipedia.org/wiki/Hydrogen_embrittlement), ammonia is much more forgiving and liquid at ambient temperature above 1MPa (10 times atmospheric pressure), not innocuous by any means but way easier to transport and store (storage requirements are similar to propane).
Petrol is safe enough that you can let untrained people pour it from one tank to another. Spill a little, no problem.

Ammonia is a gas at standard temperature, and will be transported and used as a liquid under pressure. If you expose liquid ammonia to the atmosphere, all of it boils off rapidly. The IDLH (immediate danger to life and health) limit for ammonia is 300 parts per million. If you release 15 grams of ammonia inside a typical garage, you have exceeded the IDLH threshold. If you spill just 1 gram, the smell is so strong the average person is running away in fear.

Can anyone confirm that this is simply a way to package hydrogen into a safe transportation medium to international markets (from Australia as an example) and then converted back to hydrogen when it reaches the target country?

Put it this way, is it converted back to hydrogen before it’s pumped into the car? I kinda like the idea of ammonia being converted into hydrogen in the car but judging from the news reports we have seen here in Australia the membrane technology looks quite large... more something one would see in a refinery than a car.

So my question is: at what stage would the ammonia be converted back to hydrogen; at a refinery, the service station or in the car itself?
I have gotten exactly 1 speeding ticket in my life.

It was for $200 in highschool and it stung.

If i got that same speeding ticket now, it would not sting nearly as much, and i would probably be over it by the time i went to work the next morning.
The most interesting concept is that of shared spaces- it’s a bit counter intuitive, but if you put cars on the same level (figuratively and literally) as pedestrians, cyclists and other road users you can significantly reduce accident rates. You do this by removing curbs, signage, lane markings etc. This encourages road users to pay attention to the road ahead and slow down, and also makes the whole area a nicer place to be in.

The journey time may seem slower to car drivers, but given you eliminate most major accidents the average journey time is probably the same.

This always sounds phoney to my ears. Move to a suburb to have a large house (3 bedrooms!), vote for parties that build roads instead of public transport, despise public transport, don't walk 100m but go by car, don't own a bicycle and then "I couldn't live without a car".

Yes they can't live without a car, agreed. But this is by their own choosing.
The pressure is to finish in a tight deadline. Whether an exam or a delivery date. I'm sorry, as a STEM graduate working in the field for a long time, saying that being able to work under pressure is not important strikes me as very odd. Working under pressure is a skill that cannot be replaced or compensated. You can't borrow it, you can't google it, and it's pretty damn hard to acquire. So the 15 extra minutes one receives for an exam today might turn into 15 extra hours for a project task tomorrow.

Everything about academic studies is an arbitrary "neutral point". The quantity of information for one topic, the difficultly of the exam, the time allotted.

It's exactly like saying that you don't actually need to show all that knowledge during the exam since Wolfram Alpha can do that for you. And in real life deadlines are no longer like an arbitrary exam time or even a standardized interview test. They're usually as tight as the best people on your team can afford. That becomes the "neutral point". And that's when it will matter that two people that previously looked equal start performing differently.

An exam tests you for a lot of things and they just lessened one. Which isn't in itself a necessarily bad thing if it didn't give ammo to every person claiming that men are better at STEM. Now their bias is backed by universities so good luck fighting it.

*Just highlighting again that this is discussing the "increased exam time" topic, not the "let's change results to exclude women" topic.
Yeah it's a stupid idea. But outlets can't all be on the same breaker, otherwise you would not be able to run an average home.

I think the goal of private prisons is to make more money (which is easier when spending less money and keeping prisoners longer, which also makes them more likely to re-offend), and the goal of politicians is to appear tough on crime and respond to lobbying (by private prisons).

Or something like that, anyway. Alignment of petty individual goals usually makes more sense than grand conspiracies.

C is a perfect language for writing games into; C++ has some extra sauce that makes some things easier, faster to write and more correct.

There is no actual need for a new language for writing games; that's why so many, including the author, give up. C/C++ has the 90% of what is needed to write any application, and the rest 10% is simply elusive and might not even exist.

So if you look at a lot of LSM databases they basically optimize for write throughput by design but also ultimately spend a lot of time on compaction of sstable like file volumes. So we avoid a lot of compaction of volumes together by making volumes time window based rather than other limits like heap size, etc. This means that your resources ultimately do less work and should cost less. The flip side is that you do need to make sure you have enough heap for your mutable data (which is fine in the steady write case, but for back fills means you should be more careful and use libraries to coordinate the backfills)

These sites tells you all one needs to know about government/police accountability in Denmark. A few examples:

Several people died, about 10 years ago, between being arrested and arriving in prison. They were entirely healthy before, and showed signs of getting severely beaten. The state refused to even investigate the police officers involved, and none have received any punishment (or even had their names released). Needless to say, and I'm sure completely coincidentally, a judge ruled the "lack of perpetrators" (hah!) prevents the state from getting sued from any wrongdoing.

The Danish government abducts children based on the say-so of a single government employee that isn't even a psychologist (this is policy), then has on several occasions the police beat up parents that attempt to file a complaint.

The Danish government steals Jewellery of immigrants, and has that practice as a policy (there is no other valid word for the practice, despite that it's "legal". It's stealing. No question whatsoever)

Denmark police officers beat up refugees being deported, then brag about it on social media. Needless to say: the state strongly objects to any punishment for these police officers.

Let's just not mention what the Danish state did to Inuit Indians in Greenland, on many, many occassions, including recently.

https://www.nytimes.com/2016/12/20/world/europe/denmark-refu...

The thing that you need to understand is that when push comes to shove, Denmark legitimately counts as a country where "this doesn't happen". Where the police behaves really well. That says a lot about how police forces and governments behave, irrespective of where they are and how they legitimize themselves. Denmark may not be the best country on police behavior, but it's probably in the top-10.

Every police force, every government, will abuse any power they have over people for the dumbest of reasons, every time, again and again and again. They must not be given one iota more power than absolutely necessary and need to be thoroughly checked at every turn.

Your comment got me wondering about the NYPD. Specifically, when I visited New York last March I was struck by the number of police vehicles visible on the street. It felt like there was barely a block which didn't have one or two police cruisers parked on it.

I live in London and by comparison it feels rare to see a police vehicle at all. Nevermind just parked along a random street.

I guess this was mostly due to timing; it was just after a major snow storm. Comparing the budget and number of officers it's not that different £3.2B and 30000 officers vs $5.6B and 40000 officers.
That would be a fair take on it. If you wrongfully imprison anyone, they get compensation. If all evidence points to them, but they was found not guilty, then they were wrongfully imprisoned and the intent and "why" doesn't really matter to that person.

"Wow, that's a really good photo! You must have a great camera!"

This article hits on a key thing - the main things controlling the quality/interest of a photo are composition, subject, and exposure. The main dimension "really good camera!" helps in these days is resolution, which has approximately zero to do with photo quality.

edit: I have a print of a favorite photo of mine above my fireplace mantle. It was shot with an old Motorola RAZR, at 320x240px. It's pixellated like crazy in print. It's also full of high-contrast problems - a large blown-out splotch off center from directly facing a light, and the mere shadow outlines of numerous hands in he air in the foreground (it was shot at a Flaming Lips concert). It's epic and beautiful. Why? Good composition, and interesting subject matter (hands in the air, facing a shadowy barely-recognizable human outline).

Great camera, indeed.
The fact that it’s a “non functioning future” is exactly why people are concerned. It’s entirely possible to regulate a set of activities out of existence if you make the cost of compliance too high. In this case the per user margins are low (FB ARPU is about $25 before expenses).

If the system is broken/to blame, then the system should be sued. What if the state had to pay compensation in cases of "honest" mistakes? Then the state would start having to try harder to not let innocents get imprisoned.
I contribute to an effort to run a clinical trial for applying statistical models to drug-resistant epilepsy, for patients who will undergo surgery. The results are complex both scientifically and morally. We saw a patient undergo a "failed" surgery in the sense that seizures continued but GPA shot up to 4.0. That patient is coming back for another surgery, but clinicians aren't sure what to do. Not to mention that total cost is something like 50k+ euros: what other pressing problems could be solved with a large budget?

Outside of invasive neurosurgery, it's also difficult to draw the line between stimulation & behavioral protocols, which can rewire the brain, that are good and those which are bad (for whom? by what metric?). The questions have little to do with neuroscience imo.

>"Isn't that the complete opposite to what teaching is about?"

No, it's not. Higher education is not adult daycare. If I have half a class screwing off and playing video games _in class_, and the other half desperately trying to improve their lives.

I used a very strict grading policy, if you don't turn in your assignment, you get a zero, period. All it takes is 41% of not turning in your assignments and your class doesn't apply to your degree. (ie, failure by default)

Are you suggesting I commit fraud to let these students pass? I did not "fail" them, they failed themselves.

Edit: Fyi, 100% of all my students that failed did so by not turning in assignments. 100% of them.
You believe that a student that derives a proof from scratch is less knowledgeable than a student that rote memorizes it out of a textbook?

My argument comes from the perspective of the real world.

As someone involved with hiring for a company that consistently produces high quality, critical code used in important systems, my experience is that "working under pressure" is pretty far down the list of important qualities.

Ask HN: How to start reading the source code of an open source project
I am very interested in contributing to the open source community, and hope to eventually be able to create and share my own projects with the community too.

I decided to learn by reading and analyzing the code of already well established project first, and get to know how projects are structured. But it seems very overwhelming if I just try to sit down and start reading the code without a clear path or strategy in mind, even if the project may be a relatively small one (a JS library under 7k LOC for example). I don't know if I should read the code from the entrance point to finish (which seems to require tons of patience), or start from the usage POV (how some features are implemented).

Does anyone have some advice for reading and analyzing a project?

Thank you!
