After watching "Orange is the new black" I thought prison was a really really dark place. Sexual assault is probably worse than worrying about next guy stab you.

While reading this article, I entertained the possibility of robot guards. The only problem is that prisoners can break them or alert the robots. Any idea how to keep these robots safe?

What I feel is missing from their analysis is a breakdown of corporate profits per employee, along with some hard figures, e.g., how much profit these companies make per capita. It might or might not be enough to make a dent (for example, $100 million split among 100k employees only comes to around $1000/year for each of them).
I really try not to, and this makes me a sad panda.
Very Cool.

Using RTGs for power gives the rover a ton more flexibility though, and helps make the most use out of the time that it has. I remember from reading the Mars and Me blog (written by one of the rover drivers) that the cyclical nature of solar power put some pretty big constraints on the rovers. It wasn't just a day/night thing, they had to be really careful about the orientation of the rovers' solar panels during the martian winters. A lot of the time they'd just park the rovers for the winter. Plus, the waste heat from the RTGs can be used instead of electric heaters.

Here are my replies to your questions:

* The mobile company does not have access to your data. They just issue a special SIM card that stores your private keys. Unlike the article states, there is actually also a small piece of software installed on your phone that is later used for authentication and signing.
The way it works is that you go to a site where you want to log in (I'll use Estonian government portal https://www.eesti.ee/eng/ as an example here), you press Enter (or "Log in" or whatever the button is called on the site) and choose "Login with mobile-ID". In Estonian government portal both your phone number and personal code are asked as "usernames" but some sites might ask either one of them (depends on the site's owner). Then after a few seconds your phone will display a screen showing that a connection is being made.
At the same time you will be shown a "control code" on the browser screen that you will have to confirm on your phone. This is done in order to prevent some forms of man-in-the-middle attacks. Then you're prompted to enter a mobile ID PIN1 code (used for authentication) into the phone. If PIN1 is correct, the screen on the phone disappears and the website is automatically reloaded with a logged in screen. You can cancel the authentication procedure at any moment. PIN2 is used for signing and works the same.

* Obviously it would take a lot of time to answer all the problems posed in the Wikipedia. I would disagree, however, that Estonian e-elections are easy to tamper. As Estonia is on the forefront of e-voting in the world, all these problems are addressed and analysed in great detail by our Electronic Voting Committee (http://vvk.ee/general-info/electronic-voting-committee/) that is involving leading e-voting experts in their work. There have been many debates about e-voting and rulings by our Supreme Court. The process of e-voting is very transparent (you can start reading about it here: http://vvk.ee/voting-methods-in-estonia/engindex/), it's heavily audited before, during and after the voting, the software is open-sourced (https://github.com/vvk-ehk/evalimine) and very well documented.
But to give a very high-level answer to your question about recounting the votes - there are many different applications and servers used in the e-voting process that keep traceable logs. If recounting is needed then these log files are used in order to determine if votes were tampered in some constituency.
How do you know if you are talented enough to pursue an intricate field like Artificial Intelligence? Or is it merely a lot of hard work?

I wonder if there would be any way to implement some alternative identification system that would enable the benefits the article mentions, but still allow for privacy that does not require a trustworthy government. I think, if the government can be trusted (always questionable, but sometimes true), a national ID is clearly an efficient solution. But if government can't be trusted, then maybe some kind of decentralized pseudonymity-based system could work. The state could tax the pseudonyms, they might hold the access rights to medical records etc. Of course this would be cumbersome and allow a certain level of fraud, but might still be an interesting alternative in hostile environments (the state either opposes what one does, or at least does not support it). Maybe one should look into how guerrillas and organized crime identify people that belong to their networks.

"forced conscription" is a tautology. And frankly, "around the time of America's moon mission" was also "around the time of Mao's 'Great Leap Forward'"... where tens of millions of people died due to pure political incompetance. The death count was an order of magnitude worse than the horrific farce that was the Vietnam War. Hell, even when it comes to just the Vietnam war in its own context, US conscription was one of the smaller immoral things about it.

But ultimately, counting past misdeeds doesn't help us plan for the future. We're here now, and we're looking forward. If country X was the worst polluter in 1950 and isn't now, what good comes of castigating X now? We wouldn't castigate modern China because of Mao's Great Leap, why do the same to the US from back then? There's plenty of modern concerns to deal with anyway.

Ask HN: How many vacations do you take a year?
Also do you take extended periods of time like 15-20 days, or small periods like 5-days? And also what kind of things do you usually do? Travel, visit family, work in side projects, etc

I'm curious to see if there are great differences between people located in different parts of the world, who work in startups vs in more established companies, etc
I agree with you, that the 20th century was better than the 19th and the 19th was better than the 18th. Thus I disagree with PythonicAlpha, who said

I'm looking for a site that is basically a collection of Twitter profile pictures. You sign up for the service and in doing so, authorize others to use your Twitter profile picture for their projects (e.g. say, as a dummy user in their app). I think the license was for personal projects but it has an option for commercial projects as well.

I vaguely remember seeing such a site (on HN?) once upon a time ago but I can't seem to find it. Does anyone know what I'm talking about?

Why make this so complex?

Imagine you go in a hotel room, all this stuff is written in Chinese, you just woke in the night with an urgent natural need, and you just want a light on right now! So you have to read a sign with "go to bathroom"?

I think the idea of Don Norman is actually good for a big shared meeting room, were different people will have to change the lighting occasionally.

But for homes (and hotel rooms), just place your switches in a logical place and avoid too many lamps, that should be enough.

Or maybe this: have switches on main light at the doors of a room, and then each individual lamp has its switch on its cord. Wouldn't that be good enough?

>Old colonial power what a laugh, are you waking-up from the 60'?

Not sure what you mean. France has had extended colonies up until the sixties, so it's very much one of the "old colonial powers". Is there another way to put it?

Fact is, they still like to meddle worldwide, and they still have claims on places that they have no place to be except by their colonial past:

http://en.wikipedia.org/wiki/Overseas_departments_and_territ...

Not to mention stuff like this:

This sounds awesome, but it also sounds scary. If I understand it well, the government issued the certificates for all its citizens it can both know what everyone does and impersonate them. I wouldn't mind that much if they were mundane operations, but things such as voting is of extreme importance.

Oh, and the fact that the id is built in a manner that makes sure the person has to be born in Estonia is kinda odd. No strangers allowed ?

Anyway, has anyone details about technical implementation ? That would be terrific if it could be more widespread.

I remember reading that piece when it came out. I've never made a prison rape joke since, and I always am willing to be the person who makes an uncomfortable pause to hose down someone prison rape joke. Racist and gay hatreds found their support in 'harmless' jokes, and for that to change, the jokes had to change. People still tell prison rape jokes (and include in plotlines) where they would never use a racist or homophobic joke.

So the best way forwards to work against the prison rape meme is to be that person who says 'well, I don't find jokes about rape funny at all.' You'll get rolled eyes and mutterings behind your back, but people will look back at this period and wonder why this was such a big public joke instead of a terrible injustice.

Does anybody know what symbols appear on the other 19 faces of this die?

Also, has anybody run a Chi-Square test for determining the fairness of this die??? I wouldn't pay $17,925 for a loaded die.
The better argument, I think, is "Do we need that much optimization?"

Does the trial and error performed by a casual switch user cost us so much that spending the money on custom layout light panels makes sense? I think only in a very small set of applications.

To counterpoint your second paragraph: The existing wall switches are much more than a poor first time experience and require more cognition. When using the "efficient" vertical wall switch panel, you already have to import your full object recognition library without errors. You then have to call up your list of mappings between rooms and switch position on the panel so you can flip the correct one.

With the map, you only need to load your scheme of the office into active memory to select the appropriate switch. Further, the map provides error checking for your cognitive model, confirming / reinforcing the true layout (in a complex map, a user is bound to forget a room or take longer to recall it's location without the external map).

Anecdotally, I lived in my family's third house for a year and a half, and never completely memorized the functions of the 6 switch panel in our front hall.

Imagine an office, where different panels control different light banks depending on where they are in that large office space. The common user (average person in the office seldom turns on or off various things) will need to hunt for the right switch.

Code in the various US cities I've lived in generally requires switches for a room be at a certain height and a certain distance from egress-ingress doors. I think it may have something to do with handicap accessibility, but generally there's a reason in most modern homes, you don't have to think about where the switch is.

China had enough farmers moving into industry. Slave, prison and child labour may happen, but they are not particularly efficient and so don't make much of a dent in overall figures.
It really depends on the company. I think 5 years being a long time is very much a startup-sector mindset. It's not uncommon for good devs to stay with bigger companies 10+ years if they like the job and working conditions (pay, hours, benefits, etc.). The classic 40-year IBM tenure is maybe no longer as common, but that doesn't mean everyone has gone all the way to the other extreme of only 3-4 years per company.
Notice how every single entity is taking part in this.
I have a friend who works on security systems for jails. There are plenty of areas unrecorded. There is cost for one thing - prisons are large places and recording all of it is expensive. There is also the hardware - all cameras etc are a possible source of bits and pieces that could be made into weapons or other contraband.

Hearing the security procedures that goes into taking actual tools into a jail makes your realise how locked down they are - every single item (down to a set of keys) has to be inventoried on the way in, and on the way out. No phones taken in - no exceptions. Bear in mind that staff working on security systems never get in the same space as prisoners - it's not like they're fixing cameras in the cafeteria while the prisoners mill around.

As an aside, he is investigating the use of automated drones for doing perimeter patrols. They are good at flying a set pattern with a camera payload. But there are many kinks to work out.

I don't think that the argument is that ORMs are bad, but that it shouldn't necessarily fall into the scope of a web framework. I think you could reasonably argue that the primary task of a web framework is to be a meaningful abstraction layer over http requests and http responses, but on the other hand I can also see why someone would disagree. In some sense you could make the same argument against template rendering systems.

Personally, I work a lot with a database setup that is managed primarily through REST and JSON-RPC interfaces, which makes a framework that lacks ORM a perfect fit, and I'd rather use something like Flask than something that sets me up with an ORM library whether I need it or not.

That's possible (I have a very vague knowledge of the antitrust laws in the US). But a good antitrust law is better than no antitrust law. Do you think that a secret price-setting agreement between AT&T, Verizon and Sprint should be legal? It would be profitable to these companies. In a model, competetive market, this wouldn't work, because a competitor would immediately appear on stage and started offering equivalent products for lower price. But the actual market is absolutely different, that's why regulation is needed.
For homes that's okay. Except overhead lights are not as nice as lamps, so turning on all the lamps you use with one switch is cool. Modern high efficiency LED bulbs can have odd lighting so having a few of these in lamps gives a much nicer effect.

And we want to encourage people to turn off lights when they're not being used, so a single switch is again useful. This might be saving tiny amounts of energy, but we want to move to a world where this kind of behaviour is built in.
they claim ownership over whatever you create, including stuff you do in your off hours, and any ideas you may have had.

When the U.S. puts as much money into something as the mars rover (that isn't for killing or spying), red-blooded 'mericans want to know they're getting their money's worth. If you design a rover that's supposed to work for 10 years and it dies in 10 months, you F'd up. However, if you publish a Scotty estimate of just 6 months and it lasts 10 years...

I don't buy, even for a moment, that the mars rover wasn't designed to last. It was indeed well designed and built. The estimate for it's expected lifetime, however, was more a function of politics than engineering.
That is amazingly clean! I've been using Textastic, but this looks worth a try!
A Swedish perspective:

By law you are granted 25 days vacation per year, assuming you have worked enough to "earn them", generally you get 12.5-13.x% extra salary per day worked that goes towards your vacation.

The law also says that you have a right to 4 weeks uninterrupted vacation during the June, July and August. At least two months before the (requested) vacation you must get a definitive decision. The employers are not allowed, by law, to change their mind about granted vacation time.

I believe I saw a study that recommended shorter, more frequent, vacations as the best way to recover from mental fatigue but I assume that there is a lot of opposing opinions on that matter.
So do you mean that all the answers which can pass the test are the best answers

Yes, what I was trying to say was that the performance required is just that to pass the test, not more, and the dataset is a few MB here, not 4GB. This is actually really similar to a lot of problems in real life; you can spend ages trying to find a platonic solution when a simple solution works fine given the dataset and requirements (return an answer within 200ms for example). Sometimes simpler is better, and even if you can improve the solution, it won't really matter to whoever pays the bills.

There are lots of solutions though, I tried a few just out of curiosity and you can of course improve on a hashmap - the possible solutions to a problem this small are pretty similar whatever language you choose, and sometimes when a dataset is this small other more complex solutions are slower (unless you preindex).
