I hope they - both the article authors and the trainers being described - know what the 21-foot rule is supposed to mean. A person with a drawn knife 21 feet from you does not mean that it's time to shoot them, even if they haven't made a move towards you. It means that the time for a healthy person to run up to you is close enough to the time to draw and fire a holstered weapon that you're at risk, so you should address either the closing distance or draw time by backing off or behind obstacles or drawing the weapon before any attack starts.

Police officers in the United States, as well as in Europe are trained to shoot for the center of mass when engaging an armed attacker. Do you know why? Google "Tueller Drill" for an understanding of just how dangerous someone with a knife is to an officer - at 21 feet away, that person can close the distance and kill the officer in 1.5 seconds.
I have to ask: why aren't you using the reply link?
"Oh, you can't go back to knowing who is allowed to send what number. Things are too mixed up, and it'd break many services. Including many uses of 9-1-1. It's far more difficult than, for instance, preventing spoofed IP source addresses."

That's interesting. Why is that?

Something is very different about the way the Police in Germany approach situations...

You're not wrong, certainly--US police do approach things differently. Perhaps US citizens respond differently. I think there's more to think about than the very surface of the data.

We all know what ultimately needs to happen.

Marijuana needs legalized. Minimum sentencing guidelines need to be replaced with maximums. For-profit prisons need to disappear. More work needs put into counseling and mentoring at-risk youths.

But how do we get there? Do we find another politician to hang our hopes on? Last time I voted for someone campaigning on Hope and Change we saw more civil rights disappear than ever, and Gitmo is still running.

They're not really there yet, though; right now it seems like Tesla's still raising capital via the Model S and (eventually) the Model X. A significantly-cheaper Tesla (which probably ain't the Model X) will probably arrive alongside the new battery-churning Gigafactory they're building here in Reno (since that'll allow for better economies of scale with the batteries at least), which is slated for completion by around 2017 IIRC.
> Flashbangs, fully automatic rifles, armored vehicles, tanks--those are some military weapons that have no place in a police force, IMO.

Not sure what the etiquette of HN in replying to deep message threads is so I'll try it here. We'll see if it sticks

As far as I understand police officers on the streets do not routinely carry flashbangs nor drive armored vehicles. They do have an AR-15 style rifles in the patrol cars, but those are not fully-automatic though they do look like military M4/M16.
Flashbangs and APCs are SWAT team toys.

Yeah, we should have force employees to meet the racial/age quotes. Not hire based on skills and employers decision, but based on government messing with freedom to do the business.
Yeah - this is where Anders shines. Generics were brought in primarily to avoid boxing/unboxing costs of value types, but really are incredibly powerful when used properly. And I'll say that generics in C#/.NET are done very well. Every time I use Java, I want to use generics until I remember Java's generics are confusing and almost useless.

I really miss having them when doing work in other languages, even with some of the covariance gotchas, they're just amazingly good.
The article often mentions school disctricts and their effect on house pricing. I've heard the same thing time and again from relatives in Palo Alto.

It's awkward for me to see how the US restricts free choice between public schools. In this part of western Europe, except for queueing on enrollment and capped numbers, you just go to the school your parents decide to put enroll you at.

If understand correctly, the public school monopolies in the US are because mostly local taxation and much less higher level (state or federal) taxation funds local schools.

It might be interesting to see an experiment where kids from let's say East Palo Alto can go to schook in Palo Alto if their parents want so....

This is most likely the problem - the number of cases where patients die from drug delivery mistakes is probably in thousands if not tens of thousands. The cases where someone deliberately administers a dose, via a machine are likely to be zero (because I have not heard of them)

So any cost benefit or risk analysis is going to worry about the drug.
I learned about methylation (not in any detail) from my mother. But not as a "fifth base" -- she told me that methylation was added to DNA strands and that it was how you could distinguish maternal from paternal DNA.

It's definitely not true that "we're not sure if base modifications matter much". We know they matter; you can get quite different results from the same genetic change in a maternal chromosome vs a paternal chromosome.

Anyway, I assume methylation was covered in her curriculum at some point, either as a biology undergrad or a med student. So your answer is either "because you're not reading the right books" or possibly "because methyl-cytosine is clearly a variety of cytosine, which is one of the four 'classic' bases".

Sure, but in this case it wasn't an accidental misstep, it was deliberate. Other cases would also have to prove intentional harm vs. some harmless oversight.

Who Can Push for Change Within a Company?
It most definitely is a luxury item, but not high-end luxury; it's interesting how the sales corrolate with the price. If you look at Scandinavia, the Model S is around the same price as a BMW 5 series and people go "OMG! WANTS!", whereas in the UK with essentially zero subsidies it competes with Aston Martins or the Maserati Ghibli and the posh people go "Bah, no thanks".
Having read similar perspectives I was always annoyed that there was no way to essentially pause the charging and perhaps run via trickle charge at a set percentage, so if I'm tethered to a desk for a week I could keep the battery at 70% and then choose to bring it to 100% if I expect a long day away from an outlet. Perhaps this is not plausible for some reason? Would it be control required at the battery firmware level? (Referring to an Apple laptop for example)
Call me a cynic, but on the asset forfeiture part, how these things usually seem to go is that a few years after somebody decides that it all goes to education or something, the jurisdiction's budget going to that gets cut correspondingly and reallocated, possibly to the law enforcement department. Then when you want to reform asset forfeiture, you hear "But what about the children in the schools it's funding!".

That's why I'd rather see them just get rid of it entirely while also cutting back on the War on Drugs.

Thank you for this comment (and your service).
>However, I don't think it's true that the charge controller is just a cheap way to improve efficiency; it's actually necessary to keep the battery from exploding like a firebomb when you try to charge it.

You only need to worry about it when you're riding near the edge of what the batteries can handle. If your solar array outputs 4 volts and needs a minimum of 6 hours to mostly-charge the batteries, and your batteries are in a nice cool basement, I'm pretty sure you can just hook them all together. It wouldn't be ideal but I don't think you'd have any real fire hazard.
There are tons of influences from ObjectPascal:

* Range-based subtyping: You can declare a type as being an int of 1..5. Many Pascal-derived languages (Modula, Oberon, Ada) have this.

* Ranges are first-class values and can be used in loops and case statements: "for i in 0..10".

* Arrays: "array[1..5] of integer" becomes "array[1..5, int]". Nim also has open arrays, just like ObjectPascal.

* Enums. Almost exactly like Pascal.

* Sets, eg. "set[char]", which can then assign things like {"a".."z"}, almost exactly like Pascal.

* Functions like ord() and prec().

* For a long time Nim used Borland-influenced naming conventions (mainly three: TFoo for classes, PFoo for pointers to objects, FFoo for fields). Fortunately this has been deprecated.

* "var", "type" etc. being block-oriented and used to declare multiple things on separate lines.

* Functions/methods are called "procedures". (The Nim manual insists this is more correct. I'm not so sure.)

* Case insensitive identifiers.

Point (https://point.com) takes the biggest single asset that most folks have in their lifetime - the home - and makes it liquid, divisible and tradable. Point's first product lets homeowners "sell" fractional equity in their home. There are no monthly repayments -- instead, homeowners get a tax-deferred lump sum now and the investor “exits” when the homeowner sells the property.

We’re using Rails and will build services in Go as we scale. The ideal candidate is comfortable with back-end design + implementation, has the potential to be dangerous on the front-end, can build micro-services, and is thoughtful about product and design.

Define discriminate. I think you are using this word to cover up word "decide". It is his business. If he wants to hire only blond woman in their 20s - cool. But if he decides to hire based on skills rather than racial/age quotas or some ridiculous decisions - also cool. You cant change that, thats freedom of PRIVATE business.

You're correct, but we're not comparing car prices.

The original claim was that being able to pay six figures for a car puts the purchaser in rare company. For the sake of that argument, it doesn't matter where the six figures come from.
This is actually for helping you cope with websites that use masked passwords where they want you to type 3th, 7th and 11th character and you're using a password manager so that makes things funny. So you paste your password into this little box, click on the relevant numbers and you get your numbered characters to type into their "secure" system.
"Digital native" doesn't seem to violate any discrimination laws. It certainly doesn't equate to "black" or "female."

This isn't directly relevant, but a while ago (nearly 2 years, apparently ._.) I wrote a thing that generates islands based on height contour lines and heightmaps based on them...

https://dl.dropboxusercontent.com/u/1094010/island_compiled....
The other unaddressed issue in this whole debate is candidate quality:

most u.s. police forces recruit from a similar pool of people as enlisted armed forces (and less selectively), they are:
1. HS/GED + potentially a couple years of college (its my understanding that most police officers don;t hold four year degrees)
2. Pass a drug test
3. Pass a criminal background check
4. Pass a rudimentary psych/aptitude test
5. Meet a minimum level of physical fitness

A friend who was a marine and did recruiting estimated that about 20% of a graduating U.S. high school class could meet those requirements - you then had to compete with other jobs and trades that were potentially more lucrative/appealing - and in the case with the marines (and i suspect it is similar with police forces) had a couple of motivations for joining (despite what they might say)
1. kill people/beat ass
2. Serve their country community
3. family tradition
4. need a job/job security
5. Challenge
6. uniform and toys

when viewed in this context one may not be too surprised at the actions of some portion of police officers

Most people with knives aren't Bruce Lee.

Some evaluation of the actual danger the person poses is necessary. A man standing idly with a knife is not the same as some sort of ninja commando running towards you at full speed. From inevitably watching a bunch of videos recently of unlucky black people being shot by racist cops, the US police definitely does not seem to take the attitude of the victim into consideration when deciding to shoot - half of those guys are running away from the policeman. How fast can someone kill you with a knife if they're running away from you as fast as they can?

I made a generator for non-infinite worlds(specifically, Ace of Spades 0.x, which is a 512x512x63 colored-cube space) that created "faucets" for land and water, flood filled a low-res "biome" tilemap from them, and then applied some noise and interpolation to the tilemap, plus some heightmap modification to make a river. The larger number of passes creates a very "hand-generated" result, although a careful observer will discern that the edges are all slightly rectangular. One of the major benefits of the biome approach is that I could define the average height and deviations of the heightmap, making it easy to position mountains adjacent to flat open fields.

I've never seen the Perlin approach as being sufficient for making terrain that is _realistic_, since real terrain is shaped through iterative processes, not analytic ones.

I fully agree. However you must have noticed that plenty of people don't live like that. Apps for websites, or apps that closely approximate websites, are very popular. Wikipedia, Google Search, Amazon, bus and train timetables, city transit/route-planning... certain people simply seem to like an app for a specific function.
Perhaps I was overstating things. I'm not saying "don't hire pentesters". I'm saying "don't implement security in software when it can be done in hardware". If all interfaces that could cause damage are not physically connected to an external interface, the chances of anything being able to coerce them into doing something bad are... slim, at best. Not none, never none. But slim.

Certainly slimmer than just stuffing everything in the same basket and calling it a day.

And your second part is exactly why medical devices are not, or at the very least, should not, have changes done to them after-the-fact.
Note that intersections using HLLs don't work in general. The error rates become gigantic for sets that have small intersections, or whose cardinality differs greatly.

A general solution to cardinality estimations for intersections is to just use HLLs for union operations, and keep a MinHash sketch for each key as well to perform intersections.

There is a very good analysis of this technique over at http://tech.adroll.com/blog/data/2013/07/10/hll-minhash.html
Also, simply moving doubtfully would improve the current generation's poverty level, as they'd still be under-educated to compete with the affluent labor groups and still relegated to the same to same remedial jobs even if the parent(s) are aware moving would potentially increase their child's chances for success, potentially increasing their relative poverty.

Also, let us not underestimate the value of support networks from friends and family, living in an area may include aid for child care (grandparents/aunts/uncles/etc) and so forth.
You can't just go by population. America is just a vastly more violent nation. America has a 6X higher murder rate.

America has higher handgun ownership, which is a cause of many of the police shootings.
There was such an emperor in China in A.D. 209~307. The country was suffering a devastating famine one year, and a large number of people starved to death. When the emperor was reported the news that people had no rice, no wheat, no millet, to feed themselves and starved to death, he asked, "why don't they eat meat?".
Introducing Synapse Express
I was impressed by the humility of this article. It's good to remind ourselves that probably most of the cool, clever ideas we think up are over-thought/over-designed for the problem at hand. Try to solve the problem at hand in the simplest, most direct way, and leave the clever tricks to where actual performance data demonstrates that it's required.
It's not that it's wrong, I just felt eigenvalue was so quick to jump to that, you know? And as you say, it's a startup community and so on, and sometimes that seems a little... One-dimensional to me.

Part of it was actually probably my not-quite-conscious perception of eigenvalue's ideas as pretty unimaginative and lacking in potential. What about an immersive world where everything is a fractal and where all players can build new things? Everything is an algorithm with a few parameters and it's made real when you observe it. Now that's a billion dollar idea which might even be an estimation of the workings of the real world. :-)

But, truthfully, it was mostly just a play on words and GPs username.

Yea, tasers seem superior by pretty much any measure to shooting to immobilise. The only advantage I can see a gun having is range, and far outside taser range I don't think trying to shoot a leg is exactly reasonable.

They don't of course solve the problem of police using too much force for the situation - they're nasty and threatening at a peaceful protest for instance, but when the force is appropriate they seem like a no brainer.
agreed - comparing the UK's relatively unarmed populace is not a good comparison.

The problem is that the U.S. is very heterogeneous when it comes to crime and gun laws:

Illinois (strict gun laws, unsafe)
Vermont (loose gun laws, safe)
Louisiana (loose gun laws, unsafe)

I can of course imagine reasons why people like cars. I was just surprised by the distinction of poor people using public transport and rich people using their cars.

Actually I consider it a privilege to not need a car. I pay for it with higher rent, I suppose - living closer to the city center, and in a city big enough to have public transport to begin with.

I have no idea what LA is like, does it have things like 8 lane streets? Seem to remember hearing that years ago. That to me would look very outlandish, I don't think I have ever seen an 8 lane road.

Maybe some LAians just can't imagine how different other cities are? Maybe in LA parking space is not scarce, and neither is space on the roads (with 8 lanes). But in other cities it might be different, and the incentives for cars change, not just because of ideology but because of circumstances.
