The problem is that physicists and mathematicians write the worst code I have ever seen in my entire life, and I've been programming for 30+ years. To those people, everything is a single threaded, algorithmic problem, even when it is crystal clear to a formally trained programmer that using a well thought out data structure is the correct thing to do[1][2].

For example, they managed to break my Vertica database from delivering instant results (something it is explicitly designed for in "big data" scenarios) to running 18+ hours for a single SQL query.

That shouldn't be a limitation in the technology though, just a implementation detail. Emulating DoF would work whether you have a face in the photo or not, it's just easier to lock on to a face as your primary focus.

No downvote is a known issue, partly because I can't test it, so I'm not confident I'll deliver a reliable feature.

I agree that upvote should be more visible. Currently it's available as an option tucked in popup menu, as well as via swipe gesture, which is not very discoverable.

3rd one is a feature called 'deep link' which is quite common in Android. It should remember your choice if you choose 'Remember my choice'. I don't know what went wrong here as it is a platform feature and out of my control :(

Thanks for checking it out anyway.
I went to graduate school at Caltech; my time there intersected with SM for about a year, but I only learned about that when he had already graduated.

In one of the rooms in the physics building (E. Bridge), there used to be a few shelves with old theses. While checking them out one day (probably trying to kill time before a seminar), I came across Sanjoy's thesis. It was a curious little thing, unlike any of the other theses I had seen---a bit of a hybrid between a PhD thesis and a textbook, and remarkably, very readable.

That thesis was, apparently, the first version of his now famous book, Street-Fighting Mathematics. After getting lost in it for a while, I went and asked the administrative assistant if I could get a copy, and she said nobody cares about those volumes on the shelves, and I could just take it if I wanted. I still have that copy with me.

One year I attempted to audit the (somewhat legendary) class that the book part of SM's thesis was based on---"Order of magnitude physics", taught by P. Goldreich and S. Phinney. Unfortunately, the lectures were in the morning, and I managed to wake up early enough only a few times, and dropped out afterwards.

I continued to collect material on related topics over the years, and am still hoping to use them some day in a course, together with SM's books.
How much are you willing to pay for a Phabricator app?
Slightly unfashionable to say this here, but this problem isn’t necessarily something the private sector should be routing around but one that the public sector should be fixing from within.

At GDS (GOV.UK etc) we’re working on a programme called GaaP: Government as a Platform. This aims to provide components to radically simplify the difficulty of building services focused on user needs for the rest of government.

Tom Loosemoore (now ex-GDS but hey) gave this talk at Code For America last year: https://youtube.com/watch?v=VjE_zj-7A7A . It’s obviously quite long (and in my opinion worth watching the lot) but the topic relevant part comes at ~28 minutes in. Here Tom demonstrates how pulling together the pieces of GaaP could potentially lead to registering s company in 3.5 minutes.

That a private sector company could do the same thing is great, but sometimes you need to refactor the root inefficiency rather than patch the symptom.

These things are so much more satisfying to mash than their American counterparts -- often, a tiny little nubbin that's very hard to push (and may become completely frozen in winter, meaning you are thoroughly hosed).

Deployment of alternative switches (a convex masher, a touch-sensitive dingus which vibrates slightly when it detects your press) has been uneven at best here.

If that's a slight update new models of autonomous cars can also be slight updates.

Average consumers aren't sitting around arguing statistics either. They will be marketed as safer. It's plain to see how autonomous cars will be safer in many respects already (Drunk driving or distracted driving for example). The convenience factor is by far the biggest selling point though. Sleep/work/read on your commute! Rent your car out as an autonomous taxi to earn more cash!
Ask HN: Can you suggest some IOT project to work on for undergraduate CS course

"In some Australian cities, in the central business district, the traffic light push buttons don't work at certain times — for example, 7 am to 7 pm, Monday to Wednesday, and 7 am to 9 pm, Thursday to Saturday.

The rationale is that between these busy hours, the road traffic is relatively constant, and also, the pedestrian crossings are in continuous use. So the lights do their own thing.

However, the traffic light push buttons do work outside these hours, including all day Sunday."

I understand that feeling, but it's too idealistic to be practical right now. We have to accept that convenience has won. These types of social networks depend on a critical mass of users. If the choice is to hold onto principles and lose, or compromise for now closer to the direction we want, then I think we should use Wire. It is the best chance we have for a service that could become popular enough, with people behind it who might embrace it being an open standard. There are no realistic alternatives in this mobile dominated walled-garden world. Most don't even have a desktop client, and require a phone number.
Could you name one of the turkeys? Sure, some of the things you name weren't ideal, but I don't think they bothered most people and it certainly didn't seem to hit the bottom line.
To be fair, I don't believe in free trade outside equal partners.

That is, I think trade should be completely unrestricted to foreign markets that are within some economic margin (let's say US, Japan, Canada, and Germany to come up with a very incomplete list) and in any other cases should be subject to significant restrictions.

I don't like the fact that it's nearly impossible to pay someone in America an honest wage to put together t-shirts or running shoes. I don't like the fact that I'd be hard-pressed to buy a t-shirt or a running shoe that wasn't assembled by a person who is more like a slave than not.

But also,

Food is something fundamental, something important, more important than almost anything else and really easy to export the production. We might be ok letting some industries be entirely foreign, because maybe they're less essential... basic sustenance though is in a different class of importance. It's not a fad, it'll never go away unlike many industries that seek protections when they should just be allowed to die.
When I first read the headline, I saw "Many Keynesians refusing basic income experiment", which confused me because I thought Keynes fans would totally go for UBI.

But yeah, free money looks a lot like colonialism if you squint. I can see people avoiding it. You get $500 a month now, and then 3 months later, they come asking for a "favor" in return, and it would be a shame if something happened to your kneecaps. This is not reality of course, but let's just say I've been trained to avoid emails offering me free money in the past.
It's also worth noting that some comments cannot be downvoted.
Add the salary on top of that.

Higher experience commands higher salary and no company has an unlimited cash flow, even among the ones who are truly interested in the rare experiences and skills.

On the other hand, the world is full of companies and industries who are basing their business on cheap employees and lowballing.
The Fine Article says that they don't work all the time, and gives the reasoning why: pre-planned patterns in areas of constant traffic use work better. But outside those regular times mentioned in the articles, pressing the button will alter the pattern for you.

> Some rare lights stay red forever if you don't activate the thing.

This is the most annoying thing about pedestrian lights here in Reykjavík. Reykjavík has all kinds of button behavior. Some actually stop traffic almost immediately. Others look identical, and don't actually do anything (except trigger a soft sound and a vibration when the light goes green). Then there are others that are hybrid of the two and let you wait for the surrounding traffic lights before turning green. This wait is seemingly random and can be up to two minutes.

This is a terrible user experience. There is no way of telling how (or whether) a light behaves after you press the button. People are Pavlovian and gradually learn not to press the buttons from the placebo once, and then transfer that behavior to the hybrid ones, and won't cross until someone from the other side finally presses the button.

Neural networks are trained with information from the Universe. So, in my opinion, it should not be shocking at all that neural networks store some projection/model/echo of the universe (e.g. physical laws, maths, etc.).
Safety rules in the working space, I doubt those rules come for free for companies.
That seems to be concise summary of the articles point, but my first reaction is that it's a superficial distinction.

One of the researches is Max Tegmark, author of Our Mathematical Universe. In short, he suggests every theory becomes it's own universe; physical laws are representations of patterns in some kind of calculation or proof.

As he explains, although every possible theory is a universe, "most" complex theories can be reduced to simple ones. So it seems plausible that those simple patterns are more common and more likely to be found in a random (mathematical or physical) universe.

This means that neural networks are likely to work with those common patterns. One might say it because that's closer to the nature of physical laws. But more directly, that's because of the nature of mathematical laws.

Actually some of them do have bats. And most, if not all of them are sociopaths in addition to being pathological psychopaths, which tends to manifest itself in the deep financial crisis we have been experiencing for a decade and a half now. A lot of people with those disorders end up in management, especially upper and middle management. This appears to be due to the sociopathic pathology and high social intelligence.

Apparently it is not yet widely accepted that sociopaths or psychopaths, or persons with both disorders should not be the decision makers, let alone leaders; not only is that not the state of affairs yet, but these people usually cower everyone else and thus come into leadership positions. Why this is tolerated and accepted, I cannot comprehend. I for one fight and oppose them at every turn and opportunity, because I will not accept fallacies, will not accept subjugation, and will not be cowered into obedience; only logic works with me.

30,000 years ago groups of prehistoric humans had communities no larger than 30 because that was about the maximum that the hunting-gathering methodology could support while maintaining coherence. It is noteworthy that sociopaths would usually be expelled from such groups, and that they would not have more than one or two psychopaths in the group, whose function was primarily to hunt and fend off enemies, not lead the group.

Where I read that, I don't remember, but considering the sociopathic psychopaths I have to deal with on a daily basis, it makes perfect sense to me why prehistoric groups of humans did that. Once I read that, the proverbial light bulb went off, as they say.

Somehow, we have gone from that working model to a model where a psychopath, a sociopath, or a combination of both becoming a leader is actually promoted as a role model, something to aspire to, and appreciated by the society at large.

Thanks for clarifying that. I was slightly irritated as the article name-dropped bokeh but then went on raving about the processor, not coming back to bokeh to pick up the dangling reference.

There's tactile feedback for the blind on these buttons. I'm not sure I'd class the button you linked as particularly good - most people know what to look for with traffic crossing buttons, and duplicating the lesson on every (quite small) button seems a bit pointless... and useless if you don't read English (eg tourists etc). It's overall too complex for a simple function. Using a white light for 'WAIT' is also a wasted opportunity (should be a regular 'warning' colour instead).

I don't really use either mechanism, but I would guess that the ticker in the linked article (the metal bit in the middle of the arrow gives a strong click) would be preferable to touching something underneath a city-dwelling box, where muck, gunk, and whatever accumulates. That's an edge-case complaint, though.

Another thing to consider with these kinds of things is reliability, maintenance, and cost. May not interest the UX people, but will definitely interest the local councils...

Yes. It's a passive-aggressive tactic of a veiled threat.

However, the logical among you will realize, over time, that those people are insecure weaklings and that they are bluffing. They are basically child bullies dressed in suits and wearing ties.
