Didn't Siegfried and Roy hack the maternal instinct of female cats to achieve some semblance of domestication? I mean, it didn't work out very well of course, because a cat mauled Roy and nearly killed him by grabbing him by the neck (to drag him to safety, according to them) like she would a cub.

So, I think there is a hook. It's just a really shitty one. Note that the hook for dogs can backfire as well, if they try to assert pack dominance vs. their owner. So we breed really submissive dogs.

11 is a fairly odd point to pick a cut off. That article's referenced source (http://www.washingtonpost.com/wp-srv/special/nation/deadlies...) also has errors. It purports to list all 10 and above gun involved murder sprees, including cases back as far as 1949 (ignoring bombings, but whatever).

It doesn't list Starkweather and Fugate's 10 person killing spree in 1957, or James Edward Pough's 1990 rampage in Jacksonville that killed 11 and injured 6, or Mark Barton's 1999 rampage that killed 12 and injured 13, or Leung Ying's 1928 California spree that killed 11 injured 4, or Nidal Hassan's 2009 Fort Hood spree killing 13, injuring 30, or Patrick Sherill's 1986 Oklahoma spree killing 14 injuring 6, or Ronald Simmons 1987 Arkansas rampage killing 16 injuring 4, or George Banks 1982 Pennsylvania killing of 13 injuring 1.

Since the article leaves out so many well known cases it can not be considered reliable regarding its comprehensiveness. The other article which actually did complete counts of all known cases should be considered far more authoritative.

I wonder if LEGO can stave off the doom 3D printing presents since blocks are the easiest the things to replicate.

They do a lot of tie-in based LEGO sets that I believe are protected by copyright. However, their basic blocks lost their patent last year so it's open season for those!

What is with you Americans and the Constitution? If back then female circumcision would have been considered a good idea and somehow got wrote in the constitution then you will be defending it now days because it is in the constitution?

If the constitution is wrong, it needs to be changed, is just that simple.
wrt to your first point: in the article, they say:

"Will 3D printers refuse to print parts, the way 2D ones are supposed to refuse to print bills? "

That's an interesting analogy, although the outcomes are not the same (and I doubt any 2D printer would be capable of duplicating a banknote anyway).

(That being said, I can't find any references to ink printers being unable to print bills- if anyone has additional info, that'd be very much appreciated!)

Gun control gets a lot of attention in the US. I see people asserting that it works, and the only evidence I've seen is to point to the United Kingdom. Responses generally revolve around Washington D.C. Well, you can look at the number of gun deaths per capita, by country, on wikipedia:

http://en.wikipedia.org/wiki/List_of_countries_by_firearm-re...

We're #12, but of course, people aren't generally scared by suicides, which is close to double the actual homicide rate in the US.

For some reason, that chart is missing Thailand. Despite extremely restrictive gun control, they had 20,032 firearm deaths in 2000 (and I believe it's gone up since then): http://www.politifact.com/truth-o-meter/statements/2012/jul/.... If my quick math is correct, that works out to 28.8 on the Wiki chart, and nearly TEN TIMES the per-capita homicide rate!

So, what causes all the gun deaths in Thailand? Given my limited experience with the place (one month of travel), I would say it's due to the tremendous organized crime and drug trade.

Anyway, the point is: gun deaths go much, much deeper than gun laws. It's deeply cultural and social. Until the United States recognizes that it has an enormous void where common mental healthcare should be, we'll continue to have this drama. Unless you're wealthy, violent, or suicidal, there are few means to seek mental healthcare. How about catching people before they fall down? How about treating violent sociopaths before they begin acting out against humans? How about not judging people for seeing a professional for help with emotional issues?

Between the lack of resources and the stigma attached to seeking mental healthcare, the United States is a mess.
Yeah, it's mine. Take a look at my personal site if you liked this one (link's in the profile). The "how" is just few years of messing with the visual design as a hobby. The good old trial and error :)
What kind of message would that be sending to future service providers? "Don't give people access to your data for free, because if they like it too much they'll come back with guns and demand it forever."

"As for the cause and effect line you draw, hardly so clear cut. Switzerland has assault rifles in every home and a low crime rate. The UK has an effective gun ban and a very high crime rate."

Thanks for bringing that up: the Swiss firearm-related murder rate is 10x that of the UK. In a country that overall not only has a much lower crime rate (as you rightly point out), but is generally proverbially peaceful.

(Examples: when my sister moved to Aigle in the south of Switzerland, she noticed that the flower shop had left some very valuable plants outside over the weekend. With price tags, so you knew which ones to take. She thought someone was obviously in trouble, but the owners left those plants outside very weekend. And yes, nobody locked their doors.

I was walking with a friend in Basel, and we saw a key taped to the gate of an apartment building. With a note reading "Only for the owner!!".)

Switzerland is an almost comically peaceful and safe place. Yet 10x the gun murder rate of the much less peaceful and safe UK (I lived in London for 3 years).

So how does this support the idea that having firearms widely available does not have a negative effect?
Thanks a ton for sharing. My basics on this front is embarrassingly weak.

Yes, I don't understand why no one will come out and say it - such mass murders are simply the price of the freedom to have guns. If everyone is armed, things aren't going to be better, they're going to be worse, as innocent bystanders will get hurt in shootouts between armed civilians and the evildoer they're trying to take out.

One interesting thing that I read recently is that the extremely high rate of firearm murder in America is largely inflicted by and on impoverished black males living in urban areas. If you eliminate those cases/areas from the picture, things are not all that different in America from Europe. You have a higher chance of getting stabbed by a chav in London than you do of getting shot in suburban America.

Of course, there are occasional mass murder incidents (which make the news). But given that most mass murderers are white and have mental problems, mental healthcare reform would take care of those cases that do occur outside of urban areas.

As for the high rate of firearm homicide in urban/black areas, that has more to do with the endemic problems in contemporary African American culture than anything else, and will require a much more comprehensive social policy to correct.
I don't believe anybody here would disagree with you--now, please explain to what degree you believe the 2nd amendment to be wrong, right, or outdated.
I always hear the argument "If someone wants to get hold of a gun, they will and no amount of laws or enforcement will ever change that..."
In the heat of the moment can you easily get a gun? Especially if you are looking for banned weapons? How many incidents have occurred due to guns being easy to access?
This reply is addressed to Ars as well as both points are good and similar. I assume you both mean that synchronization occurs across the infected cells? Or do you mean that it occurs across the patient's heart whether or not infected? Ectopic nodes seem to fire randomly or upon certain triggers/stressor and thereby lose synchronization (otherwise how would one a patient be diagnosed). It would be handy if the virus rewired poorly wired hearts to be better.

> I don't see any reason why there can't be a middle ground between full-on war and just being an advocate of one's civil rights.

The reason the parent post ignores the possibility of such a middle ground is that some people find arguments in favor of gun control more persuasive if anyone who defends it is painted as a traitor.

To me, if you accuse pro-gun people of being "revolutionaries," call anti-homosexuality people "hate criminals," or refer to the pro-choice as "baby killers," it suggests that your actual argument is weak. You're appealing to people's emotions, rather than logic.

This is why I firmly believe that logical argument should be a mandatory part of middle and high school curricula.
>One interesting thing that I read recently is that the extremely high rate of firearm murder in America is largely inflicted by and on impoverished black males living in urban areas. If you eliminate those cases/areas from the picture, things are not all that different in America from Europe.

You aren't supposed to talk about that.
>I don't accept the premise that whatever man touches is somehow automatically tainted or corrupted. Nor do I accept the premise that man is somehow unnatural.

I accept both, and especially the second, but I'm not anti-human or anything. It's just that we have really, really, rocketed past the rest of life on Earth, evolutionarily speaking. We destroy species, entire ecosystems, accidentally with little effort and often without even noticing until after the fact, if we notice at all. We are probably within the next 100-500 years going to reach a point where the existence of other life on Earth is not necessary for our survival. We have already passed the point where we can kill off most of it, perhaps all.

So, I don't know if you could say we have a "responsibility" to other life on Earth (although I tend to think we do), but, if we want to keep it around in anything resembling its current form, we do have to consider ourselves as apart from it in some sense. If we engage the rest of life on Earth as equals, we will likely kill most or all of it off, because there really is no contest.
The hard part of all of this is primers. Virtually everything else is straightforward (propellant is hard, but not as hard as primers. Reloading from infinite primers and powder is essentially something a one-armed blind person can do with a reloading press.

Most of the parts of guns are not under much mechanical stress, and the parts which are, tend to not be the regulated items. A convicted felon could buy commercially made barrels all day long (they're not firearms or in any way controlled), which are probably the firearm part with the greatest difficulty of manufacture, along with springs.
Yep, it's Dina.

I honestly don't see the problem with (1), this is already the case when it comes to paper printers and what you are allowed to produce with with your hammer and anvil anyway. I'd actually be surprised if there aren't plenty of countries having legislation in-place that will cover exactly this, whether you use a 3D-printer or not is simply not an issue.
Could one make the argument of "typical Swiss efficiency"?
> Who actually believe in the Constitution?

Time goes on; people with guns die, bullets are used and the police arrives where that happens, guns and bullets get oxidized and everyday become harder to get. The career criminals usually want to kill the competence (other carer criminals) or the police; two sides that would remain armed.

>We arguably have comprehensive drug control. How well does that work?

Straw man; when killing another person with cocaine becomes a trend we can start discussing this.

I wish the W3C would be more creative with naming. How many different yet similar things have been called 'widgets' since the start of the internet?
The reason we Americans are so strongly tied to our Constitution is multifaceted, but one of the key tenets is that it is a so called "living document" and allows itself to be modified via an amendment. The criticism that it should not be made illegal is a criticism that we are directly in violation of a document with extremely clear language. Instead of doing so, we should do the "correct" thing and pass an amendment to correct the original language with our current up-to-date understanding.

It is my personal opinion that the reason we don't is because enough people disagree with modifying it, and so it has to be curtailed slowly (rightly or wrongly.)
The word only makes an explicitly absolute claim. Pediatricians have read the same studies you and I have read, so they know the data isn't absolute. Therefore, they are claiming an absolute where they know there isn't one. You are right that I can't prove why they do this, but I think I can safely say most people persuade using untrue absolutes in order to realize an ideological goal or to make money, and the AAP is a non-profit organization. The quote is not something that should carry weight in a room of scientists or parents. I don't think I am over-thinking something that you've posted, especially now that you've asked me not to think too much about it.
Journal is a good word. Though I noticed that it's less of "how did I do it" for me and more of "look how much has already been done, so just few more pushes..." kind of benefit.
guns are not the key here, it is ammunition. chris rock made a great argument about it, no clue if he re-hashed an old saying or came up with it himself:

make ammo really expensive.
make ammo really regulated.

ammo contains explosives. it can be used to build bombs. bombs equal terrorism. so, get the whole wrath of homeland security upon buying, selling, handling live ammo upon it. make it so unbelievably complex that people simply give up.

oh, you want to buy 9mm? sure, please apply for a 9mm cartridge license, that's forms 12, 3274234, 423-1836, t5 and 0815. process takes a year, is valid for 5mins and usually ends with you on a no fly list. you don't wanna know what you need for 5.56. and selling? oh boy.

no need to ban anything. bureaucracy was invented for exactly this. crowd control. just look at how it was applied in the austro-hungarian monarchy, kafka's process is exactly that.

guns don't kill little kids.
bullets do.
> If we legislate 3D printing to prevent weapon manufacture, we run directly counter to the idea of "Print anything you need at home!".

It's not necessary to refer specifically to the means of manufacture. Homemade weapons are already regulated. The legal risk you run by illegal possession is separate from how you obtained it.

> Is it desirable to require that 3D printers can recognize infringing mechanisms?

Again, a simpler question would be: "Is it necessary?" And the answer, of course, is no.

Seriously, this article is talking about completely hypothetical problems. There is plenty of time to legislate on 3d printing if and when it becomes a serious problem in and of itself.
I don't understand why you think that criminal record checks, mental health checks, etc. would make people who own guns into "career criminals".

As brianchu pointed out, the Virginia tech shooter was involuntarily detained because of mental illness about 15 months before he bought his guns. He then killed 32 people with them. Would prohibiting a law prohibiting people like Seung-Hui Cho from buying guns for a few years really be a step along the road to tyranny?
w = vv = v2 and it's one symbol shorter. What's not to like?
>If the constitution is wrong, it needs to be changed, is just that simple.

Yep. And there are two methods for doing just that. But they both require a fair degree of consensus, and in the US the consensus in recent years has shifted toward more freedom regarding firearms instead of less.
Hey, we can avoid the nutcases--see my list. Add stuff. Talk about other interesting ramifications. Give other things for the people to look at that aren't just "NOT MUH GUNS" or "EVIL PUPPY KILLING RIFLES".

Why not both? There is a ridiculous number of ways to kill other people, with and without guns, and trying to control them all is impossible. But making it terribly inconvenient to perform mass murder is very possible, and it will definitely save the lives of many people at the behest of a few loons.
This statistic is deceptive. Read my reply above: http://news.ycombinator.com/item?id=4931177
That doesn't make it wrong. There is a reason the public started to support stiffer sentences, after all - they believed (correctly, as it turns out) locking up criminals means you get less crime.
U.S. Secret Service Bans Certain Gold and Silver Coins On eBay
Can you please avoid using the term "assault weapon" without defining it? If you mean all semi-auto rifles, say that. If you mean scary looking rifles with certain evil cosmetic features, like the ineffectual, now-expired 1994-2004 ban dealt with, say that instead.

[edit] Okay, you've defined it, although pretty much all semi-auto rifles have magazines; I think the distinction you're after is whether they have detachable magazines, which affects how fast they can be reloaded. What you're asking for goes far beyond the 1994 assault weapons ban.

Furthermore, by "ban" do you mean grandfathering in old firearms, like the 1994 ban did, or would you run a buy-back program to "get them all"? That's in quotes because if you think such a buy back program will get most "assault weapons", I think that's wishful thinking. It's also less likely to be politically viable. At most, the anti-gun establishment will be able to reenact something roughly akin to the 1994 ban, maybe expanding what it covers a bit, and even that would come at a very heavy political cost.

None of your proposals would probably stop another Lanza. Most of the people crazy enough to drive their kids crazy like this won't obey a federal mandate to turn in their guns.

What you call "comprehensive" gun control, would have to be a ban on semi-automatic rifles with detachable magazines, semi-auto handguns and revolvers, because all of those can be quickly reloaded. If it could be enforced, it might work, but there's no way to either collect them all or prevent new guns from being smuggled in (or stolen) without extensive 4th-amendment violations. Not to mention that it would require a constitutional amendment (or one of the pro-gun supreme court justices could be replaced with an anti-gun justice, I suppose).
These same people probably spend similar amounts of money on swag for things they like

Actually, some of us just really think swag is silly. Be very careful with how you make and apply statements like that. In particular be careful of assuming the particular person you're arguing with thinks like that.
hi clarle,

I was wondering, could you list some of the more recent academic works? I've touched up on the basics and feel pretty comfortable with them so I want to try something a bit more advanced.
When I say "it would have been good" I don't mean in general principle as a means to have orderly debate. I mean: the OP gives some very valid and sensible criticisms (I speak as someone who has used Go off/on for ~2 years), and given your background and area of expertise, I would love to know what the reasons are for some of the puzzling design decisions pointed out.

You seem determined to be dismissive here, which is unfortunate because there are few others on HN who are qualified to address these criticisms.
Part of the success and 'feel' of LEGO are due to the close tolerances - ~.01mm. This is an order of magnitude (or two) greater than my RepRap Mendelmax on it's best day.

However, it will be a great boon to the LEGO community - as they will now have greater access to non-structural, unlicensed parts such as guns [1] and the ilk.
