Ask HN: What's the most difficult technical problem you ever solved
I know it's the favorite question of interviewers but i'd like to know what difficult challenges Hacker news community solved.
I'm sure people would have noticed. Hell, some may have noticed immediately. But it would have been a non-story unless everyone got an email and had to google around for what's going on and figure out whether they need to be outraged.
"Calculus Made Easy" by Silvanus P. Thompson (1910). It is availably freely online via the Gutenberg project and many other forms too. Chapter 1 is probably the best mathematics chapter I have ever read [0]. In two paragraphs, it beats most other calculus books.

I would be interested to see the correlation to income inequality and life expectancy.

I predict a direct correlation and all of the things discussed are symptoms of poverty.

That's exactly right! A subtle observation.

We tend to demote follow-up or copycat posts for that very reason. Not as much in a case like this, though, because of the rule that we moderate less, not more, when a YC startup is involved. I just posted about that at https://news.ycombinator.com/item?id=21346983.
The ToS have been rolled back, and telemetry had not been implemented yet. I (of course) don't want anyone to leave, but hopefully that alleviates any concerns if people want to.
It's really dumb. The only thing dumber is using cloud-hosted surveillance of your home. There are any number of solutions that store surveillance camera hits in your home on an SD card or hard disk.

Police can subpoena this information if they want it. They will if they need it for a prosecution. This whole practice is all about saving Amazon money on discovery requests. If there's a serious event they'll canvass neighborhoods and look for cameras anyway and approach you directly.

There are obvious issues with participating in something like this. The rules can change at any time, and you might find yourself in a pickle if you meet some vague description at a particular time of the day.

I think the intent of the name was for the millions of new computer users at the time to think 'start here' when their computer booted up. And besides, if they didn't call it Start their Windows 95 ad blitz with Rolling Stones music would have made no sense at all! (https://www.youtube.com/watch?v=chTftktWmto)

Throwaway account.

I live in northern Canada, have been to most communities up here in both Nunavut and Northwest Territories. It's GREAT, life is extremely different, but it's extremely rewarding and fulfilling.

Most people move up and either move away within 2 years, or they end up staying for a long time. I've found it to be very binary -- either you love it or hate it.

Any questions, ask away!
Office 2007 ribbon was a terrible release. I am an Office power user and I still have to dig through well hidden “advanced” dialog boxes that were previously exposed in the UI to do things that I remember Office was capable of doing.

I still hate that change.
I'd say popular magazine articles and research articles share similar demerits, just from different perspectives. The popular article is shallow and broad and overspimplified while the research article is deep and narrow and usually overcomplicated.

Thus both provide a less than ideal introduction into any novel subject, though I see most popular articles as less 'toxic' than most research articles, especially towards encouraging further interest in the neophyte reader.
Hey, another electron thread. Wait a second, did someone already mention how horrible Javascript is? The memory consumption? The minimal integration into the OS/desktop (think accessibility)? Hmm ok, I need something new...

Here it comes: chrome is inherently instable. The Google developers give a shit about their dependency management and have trillions of open source projects just literally copied into their trunk. They also don't provide any API to speak of, chromium as a library does not exist, and don't get me started about the arcane build process of chrome.

But you can't calculate the 'score' without knowing who those people are, when they voted, and what else they voted on too. The score is a summary generated from lots of information. It's not just some number that carries no value.

Mathematics is typically approached in a different way than physics. But there are some books that offer a similar perspective to what Feynman tried to achieve, IMHO. I would recommend to look at works by John Stillwell, for example 'Elements of mathematics' or 'Mathematics and its history'.

Nathan Carter's 'Visual group theory' also seems an interesting experiment, if you are interested in that part of mathematics, though I have not read it.
That's an imperfect solution for a problem that didn't need to exist in the first place that might even produce its own list of problems.

Surprisingly, according to the CDC, the rate drug overdose deaths in MS didn't grow between 2006 and 2016. While terrible, the base rate isn't even that high compared to other states, so imagine what it's like elsewhere in the U.S. right now too.

For example, in states like Vermont and Delaware the drug overdose rate tripled in ten years.

tbh, there’s a disconnect.

Large number of recent grads are flooding the application channels. Half of them have skill level that probably shouldn’t be accepted anywhere.

At the same time established veterans are highly sought after and never really needed to ‘apply’.

As a result a massive proportion of application pipeline is filled with noise. And most of them are somewhat desperate for a job. Giving the illusion that qualified people are also desperate.

This is the closest to what I do myself -- I always have pen and paper on my desk -- but the real issue is that I don't take a note when interrupted because of social pressures (its rude to ignore someone for a few seconds). I don't even do it for myself for self interruptions because I forget to.
What a 150-Year-Old Gun Tells Us About the End of Colt’s AR-15
So my concern with this mentality is that the problem really is drivers most of the time it's not something you as a pedestrian can do anything to mitigate or prevent. Generally, as a driver myself, I try to be courteous to pedestrians but I've had multiple times as a pedestrian where drivers have intentionally tried to hit me while running, as in swerved at. When my wife road her bicycle motorcycles would swerve at her and my daughter. We had a girl in our city running last year where a vehicle literally crossed the road, went offroad and ran her down to hit her then drove off. While I'm sure that most drivers try to be good drivers I can almost count on people running red lights in my area, not respecting crosswalks, and generally just being poor drivers. There's literally nothing I as a pedestrian can to to avoid a car moving faster than I can get out of the way. When running I wear reflective gear and headphones that allow outside noise in so that I can hear the road, I stay off the road in pinch points or areas of the visibility, and I still got hit when being careful. People who are normally fine outside of the vehicle turn into sociopaths and monsters when in their vehicles. So while yes there's some impetus on pedestrians to do their part it doesn't matter when vehicles don't do their part.

Hi,

I am looking for people in the image/satellite mapping industry. The idea is to map Indian farmland according to the survey no and provide the data directly to the farmer. Stack the data with the crop, soil, weather, market, buyer and it could be a solution to the whole Agri sector.
If it is further mapped with land type data, Land purchase, subsidy, infra development red tape can be reduced to the extreme and the whole process could become transparent.

I have a couple of startups in mind who have the tech platform, but not the combined application stack.

I am looking for someone from a tech background to help with finalizing the whole setup. Connect me over at dishank.zala@gmail.com

Maybe in the short term, but I would expect Stripe workers would now find the peninsula more attractive and gradually move there. There is also the Marina, which might make some ferry commutes from the east bay reasonable and even pleasant. (I still remember commuting from Alameda to Market Street by ferry to be quite nice.)

More density near transit seems like a good result.
Not a stupid question.

The problem is that a lack of money is but a proximate, and not the ultimate, cause of the homelessness. For something like 85% of those on the streets of SF, the issue is mental or physical disabilities (I'm gonna be generous and classify a penchant for antisocial behavior as a 'mental disability') or substance problems that directly impact the ability to have a job and a dwelling or any sort of normal life.

If you are in that position, finding a warm-ish place with a well-developed support infrastructure for vagrancy as well as proximity to a wealthy population for panhandling from is a really good deal.
Tried this for a while, but unless I have the window open, I don't use it. I use Wunderlist to track the "projects" that I have in my head at any point in time.

The live feed should work more efficiently with local storage (by going directly to the user rather than getting routed through a man-in-the-middle first), and the recorded video would be available in any situations where the live video is (though perhaps over a worse connection than Ring's servers have).
I agree about alcohol use being more problematic than people realize. That said, has there been a rise in drinking over that timespan? According to other comments, the answer is no.
The argument isn't crazy when you consider the ability to control and manipulate messaging. It's not different than investigating RT or other foreign funded media.
Some people are actually legit naturals though. There was this one kid I knew that didn't play sports growing up, but if you gave him a basketball in gym class you could nail every 3 pointer. He was asked to come out to compete in an important track meet because he was known to be fast and he ran a 400m hurdles race in 53 seconds with the worst possible form. For reference, in the men's World Championships earlier in the month the winner ran 47.4 with most others finishing before 49. He just didn't care for sports though ¯\_(ツ)_/¯

Makes me wonder who else is out there with this kind of talent and what kind of records could be broken/made if they tried or had the opportunity.

Creating Value in Companies Through Counter-Logical Means
Well yeah but that would require giving up SUVs and trucks altogether and bring calls of socialism because Europe already does that.
I find I do much better at coming back to solo/personal stuff if I use an issue tracker anyway, even in the early stages where I'm not so much managing bugs as chunking into bite-size pieces as you describe, so I always try to do that now.

It makes me less likely to leave the repo with some staged changes, some unstagrd changes, and no idea what I was doing when I come back to it - but even if that does happen it makes it easier to work out.
Can someone suggest good career options for person with novelty traits ?
(see https://en.wikipedia.org/wiki/Novelty_seeking).

Once you are settle down in a certain career (for example, IT/software development), not having to satisfy the itch for novelty seeking can make things really boring for you. So, my next question - how do satisfy that itch in a given career, say IT?

Here's a question about the Feynman Lectures. I remember looking at the digitized text a few years ago, perhaps right after they made the digital copy freely available, and thinking the typesetting was pretty great. Looking at it today:

Rain pants. I was a mormon missionary in northern Japan, and we rode mountain bikes everywhere, regardless of weather. Typhoons, blizzards, compacted ice and snow on the ground, all of it is actually quite easy to bike in. Assuming you already have a water proof jacket, about $30 is all you need to get some waterproof pants that can quickly be pulled over your actual pants and keeps you perfectly dry, and then removed at your destination.

Weather should really be one of the least concerns on anyone's list for cycling.

When I first discovered Electron apps, i was amazed. Now i just walk away.

I'm not saying any of these comments surrounding Electron are invalid, it's just that these things represent a kind of truthful circlejerk around the topic.

No real conclusions. It's appears to be a study aimed at making future studies better "The review enables further development of an evaluation method of light pollution in LCA regarding the light-induced impacts on human circadian system."

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2717723/
No definitive conclusions:
"Additional laboratory-based and field studies are still necessary to better understand some features of the human circadian response to light. We are only beginning to understand how prior exposure to light affects the subsequent response to a light stimulus, and our understanding of how light exposure can affect the period of the human circadian system is also limited (135)."

Improving maintenance of your Jenkins(file) pipelines
A friend of mine had an amusing story about a visit to a secure facility. He was an engineer in the late '80s or early '90s at company that made some kind of custom text search hardware. He was sent to a customer site to do some service on one of the machines.

The customer was some government intelligence agency (he didn't tell me which one). The machine was in a small room, which also had a printer. To get to that room, you had to walk through a big room full of workers at desks.

Before entering that big room, his escort would press a button beside the door that apparently signaled to those in the room that an outsider was going to come through. That would make some audible signal in the room, and start some red lights flashing on the ceiling. Everyone in the room then had to clear their desks, putting all their papers in their drawers and locking them, and returning the most secret document to their safes.

When all that was done, everyone returned to their desks and then someone would open the door, my friend's escort would tell him to not look around, and would escort him through to the room with the machine. The door would be closed and locked, with my friend and the escort in the machine room, and my friend could work on the machine. Out in the big room, the workers would take their work back out and go back to work.

Occasionally, someone in the big room wanted to use the printer in the machine room. Before they could do that, my friend had to be escorted out of the machine room, back through the big room, and out to the corridor...going through that whole "secure the room so an outsider can pass through" procedure to get back out, and then to get back in after the printout had been retrieved.

Unfortunately, my friend had a lunch that day which disagreed with him somewhat, so that afternoon there were also a few times he needed to get to the bathroom, which of course required going through the big room each time.
