If you're looking at a way to teach a basic AI for beginners (yes, even teens), you could just try Markov chains.

You can make an easy garbage text generator / automatic text-completion (à la text messages) with markov chains, they are quite intuitive to understand and easy to implement. You can even easily make an artificial player that beats you at rock-scissors-paper, in less than 100 lines of code, using only maps and the good old random function. Teens are both surprised, proud and angry when their own code beats them, especially at a game that looks so random ("hey! my own code can detect patterns I'm not even aware of in my playing!")

Although that is not for beginners (it is using go), here is a good explanation of what I mean: https://golang.org/doc/codewalk/markov/.

Naive Bayes (and how it can detect spams) is a good second step: it is still rather intuitive and is a real, industry-tested ML algorithm.
Forced Evolution: Shopify's Journey to Kubernetes
I've got the feeling this is supposed to be showing a lot more objects than it does. The timeline goes way back, but only the top bit if filled with fairly recent items.

I'm watching this with Chrome on a Mac. Possibly not the combination they made this for.
There are two different parties effectively involved and it's worth distinguishing for very practical reasons:

The human who may be sat at a PC using, say, a web browser, can contemplate anything they like about a certificate and, in principle has some very sophisticated tools at their disposal, for example a human _could_ read the name "Fun Co. Jurassic Toys Inc." in the Subject O field of a certificate and think about a TV documentary they saw last week which said this company was run by a convicted fraudster from Spain, and that might colour their opinion of the web site they thought was a legitimate discount airfare company named "Cheaper Flights" they'd seen recommended on Facebook. They might ask their IT literate nephew Steve, "Hey, Steve, one moment, does this site look dodgy to you?" and end up not giving a criminal $850 for tickets to San Francisco that never existed.

The software, a Web Browser or similar User Agent software, is not capable of such sophisticated insight. But unlike a human its mindless checks are done for every single resource in every single page. That GIF in the top left corner, the CSS stylesheet, the Javascript auto-scroll, since it isn't thinking it doesn't get bored and skip things or take short cuts.

All trusted certs, including DV certs, allow the software to do all its checks, in real time, as it proceeds. When you submit a form by pressing the "reply" button on Hacker News to insist I'm wrong, your browser will insist on verifying that it is posting that reply to a server which has the appropriate credentials for news.ycombinator.com before it transmits the reply, not a minute afterwards when it's too late. This simple, entirely automatic, verification is the only way to make it painless enough to actually get used. Any security strategy that says "And then obviously the human operator does X" is from a dreamworld unrelated to ours, a world which also has no drink driving, nothing is ever left in the back of a cab, a world where the pencil eraser was never invented.

If the browser vendors had wanted EV to have a practical impact on the actual security, rather than just the cosmetics desired by the CA industry's sales people, they'd have instigated a more complicated origin policy, but they intentionally didn't do that.

If your situation really is that your sites mostly attract visitors who genuinely had no previous connection, nothing we can do fixes the actual problem, you are asking merely for theatre, which will cost you extra money, in the foolish belief that conmen aren't going to also put on a show, and probably a better one than you, if it makes them money.

The answer is incorrect.

Your answer: 18

The answer: 18

Anyone who has taken an autograded test or two will know it has bugs. Sometimes, they don't trim (see above) or not expressed in a way that a computer determines is equivalent.

In the case in the article, we are talking about mass graded assessments, and we can see that those who have access to wealth also have access to those who can teach them to game the system. For something as small as assessments, it probably doesn't matter on an individual level - that's always been true and one of the ways that wealth keeps its statistical advantage. However, this will also creep into the poorer school districts and as that happens, this gets truly problematic.

While you are right that the point is to improve your ability to write, the feedback loop from a trained professional is a key portion of improvement. Getting students trained by machine feedback will be a further reinforcement of privilege - your writing judged by computers will become a tell-tale sign of your upbringing.

That would require making a distinction between array-pointers and non-array pointers. There, another can of worms. Probably not worth the additional complexity.

> Google, Amazon, Facebook, Alibaba, Apple, FedEx, UPS, AT&T, and WalMart are all very centralized.

And that level of centralization and oligopoly is leading to the exact kinds of problems predicted by economists for the last century: poor service, increased cost, lack of real innovation. Centralization is still as bad as it’s always been. Nothing has changed on that score.
From the C11 spec quoted in the article

> If both the pointer operand and the result point to elements of the same array object, or one past the last element of the array object, the evaluation shall not produce an overflow; otherwise, the behavior is undefined.

So although most implementations might produce an address that's relative to b, that's not actually guaranteed by the spec unless it's `&b + 1`.
Look, this is a Javascript conference, and these now are just super about getting only candidates who are "Javascript famous" or have a lot of twitter followers. I wouldn't waste your time, either applying or attending. If being on the conference circut is what you want and in javascript then you've got two choices.

1. Create a Open Source library that is suuuuuuuper popular.

2. Get a shitload of Twitter followers.

Conferences are a business, that business is selling tickets.. big names sell tickets. It's like if I have a music festival, and I open up applications to everyone. I'm only doing that on paper, realistically I'm only getting the biggest musicians.. cause that sells tickets.

If conferences are your dream... Chose a different language, because JS is toxic and the ONLY voices you will hear now are those that have already become "Javascript Famous".
How to Unshorten Short Urls
You don't need to use any polymorphism (generics or traits) in Rust. You can use it as a pure structs and functions language like C (especially if you're not using the standard library).

The argument in favour of at least some polymorphism is that it helps to minimise highly repetitive code that would be avoided in C through aliasing, type punning or other pointer conversion.
Probably not as much as you're imagining. I like just a little bit of caramelisation.

I know you didn't mean it, but honestly your analogy is kind of brilliant. It does feel that way as somebody who enjoys walking.
The world you describe, that's the problem with all those wishful thinking like communism. Just a tiny detail, like 'if people wouldn't be selfish but work for greater good', and all would be better. On that I agree.

Where we would probably disagree is how realistic this is - to me, on truly global scale (not some isolated ie swiss/swedish experiment but places with properly f*cked up work mentality and life attitude like russia or any post-war country), it's very, very far from reality. I won't live long enough to see even a glimpse of what we discuus.

Not that it makes me anyhow happy, but it's important to have a realistic view on important variables. Everybody has a dark side. I've seen even the best and brightest and hard workers to slack badly once they lose motivation, ie changing jobs. Better have a system that accepts these flaws and still extracts value for society even in non-ideal way, rather than working with some ideal human being that is simply not out there.
I think it's good that HN avoids this "feature". It would very possibly enforce an uniform group think, which will be exacerbated by the lack of subreddits which limits sub-communities from dominating the general mental landscape.
That is said a lot, but what are actual desicions that are made to conform to the C model?

What would be good ideas in CPU design that aren't made since they are not compatible with C?

(I get it that CPUs have to support some common paradigms and use cases. For example, virtual memory / process isolation, maybe branch prediction things, or support for calling conventions. However, I don't think that is specific to C).

Quotes from a military study regarding lighting:

> Dissatisfaction with the red lighting system caused the crews of many ships to alter the lighting within their work environment. Some would extinguish all lighting, and some tried a white light configuration in which the overhead lights in the vicinity of the visual display equipment were turned off, while lights away from the visual display equipment remained on. There were many complaints of eye strain, fatigue, and headaches. In addition, watch-standers reported that working under red ambient illumination was also fatiguing, made focusing difficult, and significantly impaired their ability to identify color-coded information from charts.

Similar to Glass Steagall from 1933 in the US, which was watered down over decades and eventually repealed when we reached the end of history in 1999:

Unfortunately it appears history is probably going to repeat in more ways than just cycles of crisis and financial regulation. I expect trade war and then global war in the next decade - we’ve reached around 1935 by my estimation.
It's probably because if you build such a system the banks would believe the government could bin them next time around and consequently make a "run on the banks" more likely.

It feels like none of this is really over and we are currently paying for it in our political climate.

I've been using it for a long time but I have a question.

Sometime ago somebody on reddit or here on HN claimed in a comment that f.lux does not actually reduce the amount of blue light if you measure it. Unfortunately I never saw any replies or sources, and looking for discussions about that subject were unsuccessful.

Does anybody have any actual knowledge that could support or refute that claim?

PS: I hate it when people make claims like that and don't even attempt to support it. Now I'm still looking for an answer months later.
I'd assume that the Chinese electric car and bus manufacturers, who make far more vehicles than Tesla, are making batteries at a much greater rate (or at least their suppliers are).
That's not at all how I remember it - the CD32 was a last ditch effort, and one which whilst trying to maintain some sense of heritage (mainly in the awful styling - even at the time I wondered what they were doing) entirely misplaced the value of the Amiga in teenagers minds: creativity and piracy, neither of which were to be found.

For me the CD32 was a final confirmation that the haydays of my beloved Amiga were past.

At that point, I'd already seen Comanche running on a lowly office PC and knew that things were fast changing.

A lot of people assume material from space only has value when brought back down earths gravity well. This is short sighted and naive imo. The real value is in building space based industry and settlements ie O’neil cylinders. It maybe true that a gravity well is necessary for some industrial processes. This why low gravity bodies like the Moon and Mars are important.
Maybe I'm misunderstanding you, but it's precisely because I have no knowledge of the stack frame's layout that I didn't expect the pointers to be equal.

In ancient history I used FORTRAN. For machine learning, which is my job, I use TensorFlow using the Keras APIs. There are a few interesting machine learning libraries in Common Lisp but I don’t use them professionally.

I wasn't really thinking a niche topic but a niche use-case. Google is bad at doing literal, verbatim string searches these days and all I want sometimes is like Google 2005ish era search, just PageRank based and no modern machine learning, etc. You can have it simpler than Google did at the time since SEO against your niche engine is unlikely, so tech wise you might be more like 1998 Google. The main bottleneck seems to be what others here are suggesting: there's just too much web to index these days unless you're Bing-scale or bigger.
Honestly it might be better than the current system.

I graded papers for national high school exams for a few years (non-US) and there was a strict grading guide that you had to follow which took out any and all subjective grading out of the question.

The essay section grading guide was essentially a template that was a must to follow and any deviation would result in panalties.

You had about 30-45min to grade exams that could take 4-6 hours for students to complete and none of the questions were multiple choice they were all long form questions.
With ~30 questions per exam, the time included saving the answers in the electronic grading pad and in the later years in the shitty VB application they provided. (Which I ended up hacking and having a spread sheet import function, this got me kicked out of the exam grading because I tampered with the application...).

We are already robograding papers just with mechanical Turks and in a process which is much less accurate which is why we use 2-3 graders per exam.

Until we find a better overal solution for evaluating student performance I don’t see anything wrong with robogradig exams and student work if anything it might give teachers some more free time to actually teach.
Giving people an all-you-can-eat buffet of asphalt encourages extremely inefficient resource allocation. Doing this without asking for anything to offset the negative externalities exacerbates the problem. So far the negatives of increased vmt have been completely ignored - they are not minor. Ask yourself - would you enjoy living on a busy street, or a quiet one? A wide one, or a narrow one? Which would you rather see your kid walk or cycle to school on? Which will have cleaner air? More noise? Would you rather your 85 year old parents or grandparents had to walk across an 8 lane road or a 2 lane one to get to the post office from their home?
The random AI probably should give up if it's unable to find a move after some time. Maybe if you don't see a move you can make, you can offer to draw, and your opponent gets to try and make a move for you. If the opponent can't find a move for you either, they have to concede and draw.

The "necessary" level of production as far as people are able to pay for it. In the iterated free market game power is not equally distributed, which directly affects people's ability to negotiate pay for their work.

Another way is to keep the free market as a price discovery mechanism, but introduce a mechanism that counteracts the tendency to accumulate wealth.
One of the problem was that they automatically and without customer consent converted the deposits to VIP subscriptions.

Once you cook regularly, "figuring out what to cook and then searching for ingredients at various sections of the store" takes next to no time. Most of what you buy are the regular weekly standards. Just spent two minutes writing a shopping list before you leave home.

Then for the first few days after you shop, cook the meals you planned. And towards the end of the week, open the fridge/cupboard and think "what needs to be used up?"

The more you do it, the easier it gets.

Musk's "new, innovative approaches to manufacturing" are the status-quo from around 40 years ago. Maybe he doesn't know that...

And are they really "trying something no one else has bothered to try before"? Altogether, an electric car is simply not that much more new or different from a conventional one, these days. In fact it's much simpler. A lot of the learnings of the last 40 years would absolutely apply.

My guess is that they are not even interested in taking new customers onboard. Before knowing all of this I was interested in purchasing their most expensive plan but I had a question, so I contacted them. I got an automatic reply saying that they were going to reply in 10 days. Well... after 12 days they hadn't replied yet. I contacted them again on Twitter and they just replied it takes 14 days for non customers. But again, they never replied to my questions, not even after 20 days. Not interested to buy anything anymore at this point.
