I'm honestly not all that surprised, seeing as nearly every "technology in education" initiative really just amounts to using iPads for virtual textbooks. If schools used the technology to enrich education (specifically where it would be useful rather than just every single class) then at the very least it would be helpful in teaching new skills. However, treating computers as a magical gateway to better educations will never accomplish anything and I fail to comprehend how people thought it would be in the first place.
The best part of this article is the two comments at the end. The first is by the person who posted the Reddit question that prompted the entire rant, describing how asking them question made them rethink everything, and how they ultimately settled on a UDP design just like the one promoted in this article. The second is by the article's author: "Bravo and well done. I’m quite impressed".

We have no plan for cars hitting each other at highway speeds either. We just send out the fire and police to mop up and look for survivors. Every day, around the world, more people are killed and injured in vehicles than the entire history of nuclear accidents. Over time, better road and car design has reduced this toll, but physics can only be overcome to a limited extent.

What is important is that we be proactive. Nuclear plants are reaching end of life, and will either be replaced with more nuclear or replaced with coal. Those are the choices. Coal mining kills more people than nuclear ever has.

Life is risky. By all means make sane decisions on risk but the current policy of sitting on our hands and hoping for a miracle is just wrong. Replace old plants with better designed, safer, new plants.

Hmm...there's resistance within California from the inland counties that are heavily Republican, but politically the Democrats are largely in the driving seat, plus as far as water management goes the coming infrastructure public works are backed by the voters in a ballot initiative last year, which is probably politically insurmountable. A sufficiently disastrous flood in the central valley will sideline the remaining political opposition to a great degree. Betweent he drought and the El Nino this is going to be a pretty rough winter which I think will firm up support for mitigation measures.

I'm curious to know what you consider the safest places in terms of environmental safety and sustainability.

Porting Linux to a new processor architecture, Part 2
Solar is a niche technology with a limited role to play. You need to double production in the day and add storage just to get 24hr supply. If you want more than 12 hours backup you need to double again. If you want 48 hours backup you need 4x production and storage. The numbers get quite unfeasible quite quickly. You cannot have an energy generation system that is unable to cope with a multi-day weather event, right when you need it to be producing energy.

As a load following, top-up power source for peak daytime usage, or for charging storage based devices like cars, it's great. But you cannot compare solar and nuclear because they are entirely separate classes of energy production.

It's not clear how or why the comparison exists except due to Uber being at the forefront of the current tech zeitgeist. There are many other things to compare this too. I am not clear on how informing the reader about the amount of funding Uber has raised and SpaceX's revenue from contracts actually clarifies and helps to provide proper perspective of the amount of money SpaceX has under contract. There is only mention of Uber in the title and once in the article, but the mention and comparison have worked to make everyone think about Uber (look at the current comments in this submission :))

The way I understood this, it's impossible to generate lift without creating a net motion of air. Pressure is force per area, so saying that there is a pressure difference between the upper and lower side of the wing means that the air is exerting a force on the wing. By Newton's third law, that also means that the wing is exerting a force on the air, which has to move.

I guess you can also see it from conservation of momentum. Gravity acts on the plane, so each second there is a certain amount of downwards momentum added to the system. But the plane is not in fact moving downwards, so the all the downwards momentum has to end up in the air, so it has to move downwards. The net "lift" force is equal to the rate at which momentum is added to air.

If I understand it correctly, you can calculate the lift on the wing either in terms of the pressure on the two sides, or in terms of the downwards acceleration of air--it should be two equivalent views giving the same result. Bernoulli's principle gives a way to calculate the pressures if you only know the velocity of the air (this is a typical situation in a wind tunnel, where you make movies of moving smoke puffs), but it's not a separate effect from the air motion.

"Corporations, especially at that scale, are at best amoral."
sorry, but this is just wrong.

Lots of people posting and reading this work for corporations.

Do bad actors exist? Sure. Are all corporations at scale amoral? You make them sound like machines programmed by megalomaniacs, not places created by, worked at and invested in by ordinary people. Every 'corporation' I have ever worked at has been filled with people trying to do a good job under whatever circumstances they find themselves in. Brushing off the majority of good that large companies do as an argument is not correct.

From the paper, I gather that Giraffe uses standard alpha-beta search with a heuristic for position evaluation. The learning applies only to the heuristic. I.e. they did not train a learner to point to the next best move, they trained one to evaluate the position.

This is very impressive work considering it's a master's thesis (meaning it was done in a short period of time, not that master's students aren't capable of producing top-quality work), but: 1) applying learning/tuning to position evaluators is not new (the network is deeper than usual, though it also uses features that are known to be useful, and doesn't rediscover everything), 2) the rating gap when compared to state-of-the-art engines is absolutely massive (contrary to the article's claim that it is competitive). Giraffe is a great project and it is better than almost all humans, but it doesn't seem (yet!) to be a revolution in computer chess.

Because the track record for "cool ways to land and take off" simply aren't that great. Eg, see the track record of the Osprey.

Another simple point is that current rigid landing skids provide a simple surface to land with. With "legs" you know have the problem of "landing gear" which can malfunction, rigid landing skids can hardly malfunction .... oh crap 1 leg is stuck in the "out" position -- how should I land now sir? :)

> I would imagine that the ability to land on a hillside would be incredibly useful for military operations and rescue.

Perhaps, but rarely are hill sides flat, nor void of tall obstacles such as trees. Typically in hot LZ it's in your best interest to not land. By which I mean being airborne is 1 problem, having landed -- you now have 2 problems (your static and now need to take-off). This is also true typically in rescue attempts.
Maybe so, but you know every regular guy driving a regular car would rather have a Ferrari and might even spend time looking at them even though he can't buy one.
The real promise of education technology isn't to plop computers in front of kids and hope they do better it's to get persistent, dynamic, individualized curriculum for every student.

Yes, exactly.

The largest use of computers in schools (let's stick to the educational software, even though classes may not always)

By far the biggest use is in doing what computers are good at : automating manual, repetitive tasks.

So instead of a teacher teaching spelling, the kids use a spelling program where an annoying animated characters zips around saying 'great job'.

This is just automation of the teaching that needs to be done, but without the added ability of the teacher to see who is engaged and who is not. I have first hand experience of children who don't know / don't feel comfortable on the computer and as such get zero out of the automated lessons.

Any use of computers which relies on the person being a passive recipient of the output, instead of being an active determinant of what the computer does (ie programming instead of consuming ) is just automated teachers. Fine, but let's call it what it is.
No. They are simply assembling existing missile designs and running MATLAB simulations.

What i can gather from the post is that it's because they are using Google App Engine, and GAE does not allow the use of arbitrary native libraries. Some of the most popular Python libraries that use native code are supported[1] (in the post it's mentioned that they are already using numpy and PIL), but if you need something else besides that, you're out of luck.

Uber has improved my quality of life, and improved the ability of my social group to get together despite being fairly spread out. Before installing uber, I paid for transportation maybe twice a year. Now it's closer to twice a month. That's pretty significant.

I'm glad SpaceX is doing well, but I'm also glad Uber is going well.
You might want to test some of those assertions.

Specifically the jitter one. Go on, mess up a NTP host and watch what happens.
Some of what you find googling is just wrong. Dealing with global characters is confusing, people get it wrong a lot, and suggest wrong answers.

But it's true, as far as i know, that there's no unicode standard way to 'strip accents', which is unfortunate because we sometimes do need to do it. Even if 'strip accents' is locale dependent, and may have no sensible answer in some locales, I think there are sensible ways to do it in some locales (certainly in English, for Latin characters at least), and I wish there were a recognized best practice standard for doing it that could be implemented identically in various languages (maybe there is and I don't know it?).

There are unicode standard ways to compare/sort strings ignoring accents, in at least some locales, which might get you there if you reverse engineered them and took them further.

At any rate, at the end of the day, you can't simply talk about 'unicode normalization' without talking about the four different unicode normalization forms (canonical and compatibility; decomposed and composed) -- if you do, you are definitely getting something wrong.

And also, unicode normalization forms are definitely _not_ intended to 'strip accents', that is not what they are for, they aren't the solution to that, even if the compatibility normalizations do it in some cases.

If people can get around cheaper and more easily using Uber than they could previously using taxis, that's an enabler for better productivity and quality across the entire economy.

Not even to mention that Uber, in complete opposition to taxis, is massively incentivised to drive self-driving tech forwards as quickly as possible. That will be a huge, huge multiplier on the above.

Your use of 'perverted culture' in reference to demand for improvements in transport services puzzles me. Perhaps I'm misunderstanding your intent. People getting around, seeing other people, working with other people is the very basis of, well.. everything in our economy, and in our lives.

Even if only on an academic level, I really struggle to see how anyone couldn't be excited by the improvements companies like Uber are making right now, and the potentially more drastic improvements they could make in the future, in this sector.
Walk Appeal and Public Health
There are several scenarios where computer use would not just be great but accelerate learning process:

-Teaching about planets, universe, Big Bang through interactive simulations

-Virtual interactive dissection for biology class

-Interactive geometry for understanding proofs

-Playing with molecular structure of material

-Interactive virtual model of steam engine and internal combustion engines

-Interactive excercise for basic arithmetic and trignometry

-Learning about WWII with photos, animations on map, graphs, data, videos.

I would have truely loved all these to be there in my school years. The key is that you need a great software that is targeted towards specific parts of topics. Remember interactivity is the key and only computers can offer that so cheaply and effectively even to the most disadvantaged students in remotest part of the world.

Instead of all these, when I hear "Tech for Education" it usually means, replacing books by ebooks, submitting homework electronically, ask questions in class chat rooms, recording activities in e-log and so on. Those things are triviality with negligible benefits towards actually understanding the subject - more likely negative benefit as it just adds on distraction. No one wants to do real tech in Ed like above examples because it's hard, requires lot of expensive talent and risk taking. Building chat rooms for class shouldn't even be called "tech in Ed", IMo.

Unfortunately schools are blowing 100s of million on just that and governments and philanthropists are happy to shove their cash in to creating ever more advanced chat rooms and classroom management systems rather than create actual interactive content that helps understanding of the subject.

It would have been nice if study pointed this out instead of denouncing use of computers in education straight up.

PS: No one should compare student performance with Shanghai or Mumbai. Those places have extra-super-heavy emphasis on passing exams and memorizations. You will find tons of students there who can acurately list down every single important date for WWII and without pretty much any understanding of dynamics that caused Holocast or even Holocast itself.
Exactly. The more people who come to this conclusion and start to put up a fuss like the GP did the sooner we'll solve this whole conundrum. CS != SE and people trying to shoehorn the latter into the former are going to be disappointed.

That said, I'm personally glad that my education was heavy on the CS. Nearly 20 years later (yuck) I attribute it to providing me an ability to stay flexible and learn new technologies rapidly.
I work for a corporation too. Lots of good people there. I'm good people.

I'm talking about hyper-corporations and billion dollar contracts. That many people, chasing that much money ... no one who's gotten to the point that they could with authority say "Nah, we shouldn't do this, it's wrong," ever would say that. No one at that level of accomplishment and tenure has it in them to say "Oh, and are the fish in that river really safe?"
Wow, that's just absurd.

I'd be really curious to hear what makes Dart tools awesome. I haven't played with Dart, but JS has some of the best tooling I've used. Have you tried webpack and hotloading? Have you tried npm (with webpack to generate client-side bundles) as your dependency manager?
Exactly. I thought someone wants to organize a Hackathon, or something.
I'm going to disagree. It's a slippery slope to start making comparisons like that because the logical conclusion is that you only spend money on cancer research.

Also, I think transportation is fundamental and worth investing in. And further, it's (currently) a pretty good and very flexible way for a variety of people to earn income.

I use the app on Android and it's the best HN app on Android but at times it is obvious that it is not native and it has some issues as you said. What I have encountered are

1. I get an error message "Unable to load xxxx" at times (forgot the exact message) and the app closes.

2. If I switch between article/comments it always reloads

3. At times clicking on the comments icon doesn't work when you are in article mode.

4. I can't long press on links in comments to share it to browser/pocket etc

Compared to reddit apps like Relay, the HN app does feel much more basic.

Not more comfortable, but perhaps also not something for which we should immediately point the finger at CO2 emissions. I think a more important step for California is to re-asses its priorities for water use. The amount of groundwater that the farmers are pumping is absolutely insane -- agriculture in that environment doesn't make sense. In my area, the climate isn't quite as nice, but I can dig a 10ft deep hole in my horse pasture and it'll turn into a nice pond. No, you can't grow almonds and certain other trendy foods in the midwest ... but you can grow crops that will adequately feed the populace, and it's a far more ecologically responsible place to farm. We grow tomatoes, watermelon, cantaloupe, strawberries, broccoli, green beans, blackberries, corn, and a few other things in our garden and most years I don't need to give it a drop of water from a hose. I've actually had to put a good deal of time, effort, and money into managing the water that runs off of our land (we have ~11 acres that all slope toward our house). The commercial corn field across the street has no irrigation system, at all. Although some farmers do it, watering with groundwater here is definitely the exception and not the norm.

... now if only the competition for software engineers were a bit more intense ... I blame the damn snow :).
