I always grew up thinking that police had to wait until somebody shot at them to shoot back.

It seems like "we thought he had a gun and he motioned towards his waist" has now replaced "he shot at us".

I really wish that the police had to adhere to the same laws as anybody else does. They are civilians after all.

If had a gun (I don't) and pointed it at somebody to intimidate them, even if they were trying to break into my house, I could get in trouble for "brandishing". Yet civilian police pull their guns out and point them at people all the time.

The can't believe that we allow these people can put themselves into a position where they're deciding if they're going to kill you or not, and the mere press of a small lever on their hand KILLS YOU and that this is just considered okay...

It's just absolutely ridiculous to me.
> Many fake news stories appear to support India’s ruling Bharatiya Janata Party and its right-wing Hindu nationalist agenda, said Jency Jacob, managing editor for boomlive.in, a fact-checking website.

That right there is a "fake news" in itself. Both sides of the aisle has to be blamed for the situation. As much there is agenda from the right wing, there has also been concentrated effort from the left wing too.
I do this when I'm walking around the house (no shoes allowed), partly because my heels eventually hurt when walking on hard surfaces with no padding, but mostly so I avoid treading on a lego brick or a type G (UK) power plug (though this is the first time I've thought about it, so these are assumptions).

I also run on the balls of my feet, but I never thought about why I might do that until I read an article about it a few years back.
Right, but that content doesn't seem to escape that specific subreddit (Or if it does, it is quickly voted down to oblivion). So in the context of moderators having to view objectionable content all day it is either content they don't mind viewing, or neatly packaged so it can be banned entirely if it is illegal.
Ahem. Speaking with mock outrage, as someone who goes bike camping with front and back panniers and a tent, I'll point out that my bike is about 40 lbs, unloaded. Eg, https://www.koga.com/en/bikes/trekking/collection/worldtrave... . ;)

'Course, my average speed is about 8mph. I like to stop, look at things, and read the signs, and sometimes travel along hard-pack dirt roads.

Their e-trekking bike is about 54 lbs. I know what I'm going to get for myself when I get older.
How about JEFFK style? I LIEK IT!!!111
I can't help but feel that this conversation is missing the forest for the trees. The vast majority of people need cars to get them from point A to point B. They are not automobile racing enthusiasts who demand extreme cornering performance. If this were the only thing holding electric cars back, then electric cars could easily get to 99.X% market share, at which point there are an insignificant number of ICE cars remaining.
I can't find the exact paper, but you can find a lot after reading this article popularizing the topic:

The future is here. :)
Simple minded people - those without a willingness to question and consider, will always be led around by false information. It doesn't matter whether it's rural Texas or India.

Until we instill in people a willingness to think, question, and consider, we will continue to be plagued by ignorant masses. It doesn't help when there exists an active, malicious business model designed to keep ignorant people as willfully ignorant followers. *autocorrect fix
So in other words... if your opinion is a minority one that the mainstream media don't agree with, then you're basically stuffed. Fact checkers have biases, and if they're trusted to basically fact check the whole internet for web browsers, they'll have even more of an incentive not to be fair and neutral. What stops them from basically labelling alternative media as false across the board? Or labelling based on the personal opinions of the staff who work there?

Seems like a political minefield with antitrust claims just waiting to happen.
I found this paper after reading through Jeff Dean's talk at NIPS. I recommend that, too, obviously!

http://learningsys.org/nips17/assets/slides/dean-nips17.pdf

You can generally find a paper for each section.
If you haven't done anything wrong, and then one day your home is surrounded by a paramilitary force barking instructions at you and threatening your life, confusion, inattention and misunderstanding are inevitable. If police procedures don't allow for that, they are fundamentally broken.

This tragic outcome could have been avoided many times, and in most of those cases, the difference would have been in the behaviour of the police.
I don't understand. If there is no clear way to register the vehicle, then how do moped and motorcycle owners figure out how to register their vehicles?

Oh just like that hotel shooting where the cops told the guy to crawl forward with his hands behind his head (or something like that) and kept giving him conflicting tasks before opening fire?
I never did that actually and it seems involved, hard and very limiting for what such a script could do.

I dislike talking about touchy high risk stuff like that in general since someone might think what I say is a list of things to do to be 100% secure and get burned.

What it says on [0] is a good start I guess: only textual code input, no bytecode (5.1 has bytecode verification but it was removed in 5.2 because it had flaws and gave false sense of security, there were examples of breaking stuff up with malicious handcrafted bytecode), white listing.

To not allow something (like os or debug libs) to be used just don't include it in the environment for that used supplied function (it does restrict you quite a bit though I guess...).

For memory you could use your own allocator and enforce a limit there (and probably set your own atpanic function in 5.1 and longjmp out of it because you might kill the entire program with the default one when Lua won't be able to alloc the error message itself, in 5.2 and 5.3 it's preallocated in the VM so that won't happen).

To prevent runaway Lua loops you can use the count debug hook and throw a Lua error in it, pcall will get that (just remember to reset it between calls because it doesn't reset to 0 on its own). Preventing runaway C loops is up to making sure you don't expose something that can get stuck. You could also set count to something low or use line debug hook and check the time in it and error out if the code took too long already but it might slow the code down too badly (depends on what you do I guess).

That stuff (mem alloc, debug hooks, panic, environments, etc.) is in the docs.

Long strings can also DoS the hashing algorithm and that might totally kill performance with tables, it's a trivial change to fix that yourself or use one of the patches[1]. It came up on the mailing list too. I'm sure it happens on 5.1, not sure about latest 5.2 and 5.3 right now and I don't have time to look into it.

LuaJIT doesn't also let you set the allocator on 64 bit and has some other issues with out of memory errors[2] (I don't know what they are exactly about). I guess it's out of the question if you're really paranoid (stock Lua 5.1 is also way easier to read, modify and compile IMO). I'm not very familiar with LuaJIT.

>Pretend the cop is a dinosaur or something and sudden movement will provoke him.

It's really perverse that I have to train myself to deal safely with a purported practised officer of the law.
Censoring content you disagree with is societal suicide.
> You sound like you want them to do more moderation?

> It amazes me that we've reached the point where there are commenters on Hacker News arguing in favour of online censorship.

Moderation includes improving links (such as changing the primary link from a PR note to an actual research paper), improving titles (to reflect what is actually said in an article without unrelated hyperbole from a submitter), or even just adding the year of publishing for older articles in parentheses.

I’m just providing examples that few would debate as censorship. There are certainly others. I absolutely support constructive moderation.
Well, they're not allowed to operate outside the US.

(I mean, it would probably cause an international incident and such)
like many other PDFs like this what they really are the author's personal notes, which served the purpose of firming up the author's own understanding of the material.
It's Facebook's business. They can run it any way they want. You want to promote Palestinian civil rights? Start your own Facebook.
This is the email version of when Telemarketers call me and ask to "speak with someone in the house between the ages for x-y" to which I say, "sure just a sec", then put the phone down on the desk and walk away.
For sure, but a cheat sheet can still be useful. For example, the I find matrix cookbook very useful when I don't feel like rederiving derivatives of nontrivial linear algebra expressions.
Ask HN: What will you improve in 2018 to become better programmer?
I would expect a cheaper alu frame to be "overbuilt" and heavier, probably not butted, so it doesn't seem that bad for the conversion.
I've read that paper, and I wasn't particularly impressed. Is there any concrete evidence that learned indices scale to databases with complex schemata and a large transactional volume? Could learned indices be profitably used, say, in the database backend of an ERP system?
Ask HN: What 2017 taught you will improve in 2018?
You don't have to build very many PCs before finding yourself with a bad power supply or motherboard. (In my experience these two are the most common to be non-functional out of the box.) This can be frustrating enough even for someone who is experienced.
> And I don't foresee electric cars being realistic choices for a track day any time in the next 10-15 years.

Why not? People are already taking Teslas to track days, and doing quite well with them. They're faster than the majority of random cars that people are already bringing to track days. That's why track days have performance classes, so you don't have Civics competing directly against (and getting trounced by) Ferraris.

> That said, I think it’s nice to be able to reflect the same attack vector upon the attackers to make the attack less efficient and hopefully less attractive.

If it's just bots replying - which honestly doesn't actually seem to be the case - I don't think it's going to make a big dent in their efficiency. It might backfire, though, and just cause more garbage traffic.
Forums are alive and well. Just not for pointless 'social interacting' and selfies. To give you some examples.

Interested in electronics? EEVblog forums.

Audio? DIYaudio.com and Vegalab forums.

Mobile? XDA and 4pda forums.

Mobile audio? Head-fi and Doctorhead forums.

Mobile power? budgetlightforum and chongdiantou BBS.

Yes, a big amount of them is Russian and Chinese. Yes, there is something to think about.
I mean just to look at one part of the world, but which many of us will understand, look at somewhere like San Mateo, the sub-urban area halfway between San Francisco and San Jose in Silicon Valley. Imagine living in a house with a garage somewhere like Foster City.

https://www.google.co.uk/maps/@37.5466469,-122.2920167,13z?h...

A family could get all around this area very nicely on an electric bike. Maybe you bike to an office in Redwood Shores, your wife teaches the College of San Mateo campus up the hill and she can get there on an electric bike there as well. She basically recharges it on the way back on the down hill. Your daughter goes to Hillsdale High School where she can electric bike to and works a part time job at the Whole Foods Market there which can bike to as well.

Your suburb example was flawed because not everyone is trying to get into a big city centre.

But many people on Hacker News don't use Facebook. Don't you wonder why that is?

I'm not really sure that removing blatantly false nonsense would be considered "censorship". It's more about improving the quality of the site, and filtering things that are obviously wrong.
You're lucky that your spam calls come from a human. All I get is bots calling to tell me I've won a free cruise.
Many of those responsible for that code and even directing the developers are reading these very comments.

They are making a £ v moral decision.
on a 12/12 cycle, why not split the crop in half with offset cycles? or on the 18/6, split into thirds, so that only 1/3 is off? then it would be an even/constant use of power. no obvious pattern at that point.
> I don't think you can properly learn probabilities without understanding a degree of calculus. And I don't think you can have a complete scientific education without a measure of probabilities and statistics.

I don't think the parent said zero calc or statistics (rereading the parent did say no calc which I disagree with). I think the complaint stems from the fact that many CS curriculums started, and often still exist in the math department. Should a CS student take calc classes up to level 4 or stop at level 2 and instead have more advanced courses around the computer part of the science?
Same. Adderall (plus welbutrin more recently) have been enormously effective at helping with the mild depression that have plagued me my entire life. (Adderall isn't indicated to treat depression but it doesn't hurt and is particularly effective for me when combined with welbutrin.)

Ritalin made me angry, scared, and flat out unwilling to do work (although perhaps it would have helped the concentration had I decided I actually wanted to anything).

I hope adverse reactions to one of many possibly-effective medications don't deter patients from getting the help they need.
yes, the average Palestinian without any capital or internet access will just go into his garage and start a new facebook.

What a facetious and despicable comment. As the article points out that Facebook is one of the most important news sources for Palestinians. This is effectively shutting them out of the modern communication system and a civil rights catastrophy.
I have the feeling that all of this is going to finish bot against bot.
What's the rest of that list?
I think I would have met the qualifications for this as a 14 year old. My parents were going through a bad divorce and I spent all my time playing StarCraft to cope.

I had all the signs of addiction, I stopped hanging out with friends, I stayed awake all night, ate poorly and gave up in school. More than once I recognized my issue and smashed the CD, even one time glued it to a piece of paper and put it on our bulletin board for my mom to see. Two weeks later I'd be back playing at 3am.

I needed help but I don't think my parents knew what to do.
Obvious prima facie. If we don't agree on this we don't inhabit the same intellectual universe.

Maybe your issue isn't the claim that the editorial slant is anti-white, but with my use of the term propaganda? Don't take that to mean much, I view most media as propaganda of one kind or another.
You are forgetting there is a real time & cognitive cost associated with performing analysis, especially if you are already biased on the issue. It's the same reason people can't stick to diets. People want to feel good now. So if you can give them another reason to like/hate Trump, you will find little resistance.
The need to take calculus and other math related classes in an engineering or science field is not to know how to solve integrals or differential equations in your mind for a normal 9to5 job, but it's for something extremely important in computer science an engineering in general: abstraction; the ability to, when faced with a [new] problem, hide the details away for a moment and concentrate on the important parts, recognize patterns, know which tools to use, etc. Then you can go bringing back the details when you need them, to form a solution.

You'd certainly go crazy if you start to think in all the little details as soon as you face a problem, and probably never deliver a solution on the time needed.

It turns out that mathematics are very good at, gradually, giving you new levels of abstraction to solve new problems, or old problems in new ways, etc. The important is not to memorize formulas (that's what books and wikipedia are for), but to know which one to use, and when, their uses, etc.
> Last week, newspapers here carried full-page advertisements by Facebook that explained how to spot false news.

I guess that's cheaper than hiring additional moderators, or figuring out how to temper this issue with technological solutions - but shouldn't this be a big flag to Facebook that there is indeed a huge problem?
Having unfortunately seen a police body cam video of an obviously unarmed man being shot, and having read about this one, it seems to be a case of men hitching their trousers up because they aren’t wearing a belt, being mistaken for reaching for a gun.

This is a normal thing, it’s an unconscious thing, we do it without thinking so can’t stop when told not to do it. People should not die because they’re wearing loose fitting trousers.

Americans need to be doing more about their fellow citizens being murdered by the people supposed to protect them.
How to Make a Mega Metal Foundry
What bothers me about these situations is just the entire idea of "SWAT" as practiced.

You are a cop with 5+ other cops.

You all pull your guns.

Someone comes to the door, groggy in the middle of the night. They may or may not understand you are police. They may or may not believe you are the police.

They are definitely confused/frightened/angry by your presence.

We now begin the dice rolling process.

Since every police officer with a gun drawn is now a DECIDER they get a dice roll.

Every single millisecond, all these dice are rolled simultaneously for the entire arrest process as the "suspect" is ordered around like they haven't been since grade school gym class.

This process is designed to have a weapon be discharged.
I'm not aware of any good centralized collection of them. But the articles written on the amazing durability of the scam usually include an example or two:

In what kind of society does someone call 911, pretending to be homocidal, telling them they are pointing a gun at their wife and child, that they poured gasoline throughout the house, and are going to burn it down?

The fact is there are people that really do this and someone needs to respond.

The other fact is that other people think it’s funny, or a good way to get revenge on someone, by calling in a police force to invade their home.
> It amazes me that we've reached the point where there are commenters on Hacker News arguing in favour of online censorship.

Why? Do you think that HN is a moderation-free bastion of unfiltered speech?
When it comes to the use of deadly force, the same laws apply to police as everyone else. There has to be a reasonable belief that there is an imminent threat of death or gross bodily injury. If someone is pointing a gun at you, you don't have to let them shoot you first before you can defend yourself.
If this incident began with a planned approach by the police, on the assumption that they might be facing someone violent and armed, one of the first questions should surely be why any officers outside the building were so exposed that they were concerned about being suddenly shot by the suspect. Do these officers not arrive equipped with body armour, shields, armoured vehicles and the like in a situation like this?

I used Ritalin as a crutch after radiation. It helped. Sometimes quite a bit. Recovery time span was 6 months. Now the Ritalin helps less, meaning I barely feel it's effects; so now I'm taking one or two pills weekly.

I'd love to have some effective nootropics for improved focus, cognition. Mostly to mitigate aging, grogginess from the chemo, and so forth.
Also poor eyesight, color blindness, partial deafness, &c. The reality all of these diseases/disorders are readily and inexpensively treated and not an issue in modern society.
This is what happens when everyone relies on some centralized global social network for their communications, instead of something they run locally on their own mesh network.

Well done. It does get the spammers frustrated. I remember reading about a similar thing[1] where instead of emails it was automated telephone replies and the scammers were cussing at the bots and generally super confused.

It did also manage to flood their phone lines making their call center useless for a while.

Forget large internet forums; what am I supposed to do when someone alleges that my small forum with five active members gets hit by this? It would be a death knell for any new venture that doesn't have several million dollars in funding for legal defenses alone.
:) "most" vs "many."

I don't think most users would have a terrible time. I think most users would not bother with setting up anything fancy, but could if they had ok instructions. But I think there are many who would absolutely flounder. As a technical person, I would like more security for sure.

"Security" questions should be gone. Everything important should be 2FA or have a key fob. I think just about everyone who has a phone and does online banking can understand "input the code we just texted you."
THere are so many ways this could be done which arent at all like you are proposing. And if token based they wouldnt be able to do that.
I wonder if people would be better off learning an appropriate amount of calculus and statistics by simulation, rather than by derivation and proof. You can learn a lot with a random number generator, or by breaking a function into little increments and adding things up. Doing it this way might also reinforce the students' programming skills, or gently expose non-programmers to a little bit of programming.

I love derivations and proofs, and majored in math, but they are a deterrent to most people, and unrelated to their jobs like you say. I work for a company whose products are particularly mathematical, yet only a tiny handful of programmers (mostly the ones with science backgrounds) deal with the math related stuff.

Most engineers finish college, start their first jobs, and immediately become so busy with CAD and bureaucracy, that they forget all of their math and theory.

I think another problem is: What to do with kids who want to become programmers, and have been told that they must get a college degree in something, but programming doesn't really require 4 years of college study. Many of those kids major in Computer Science, which many people have pointed out, is not the same as programming. But selective admission into Computer Science programs becomes self fulfilling in terms of the demand to get into those programs. I took a different route, which was to major in math and physics. And I ended up doing something other than programming for my career, but that's OK too.
I've heard from (a random Youtube video) that opiates mimic/activate some of the same brain circuits as pleasant socializing.
