That's an 2007 number. "Since Obama was elected" "100 million guns have been sold" (although the sales increases really started after 9/11), and more significantly, US production has doubled, and importation is similarly higher. I could run the numbers if anyone wanted, but it should be around 1 gun per US resident nowadays, although as others have noted, this is very unevenly distributed.

ADDED: on the other hand, the claim all the new ones are being bought by existing gun owners is fatuous, a back of the envelope calculation I made would have us existing gun owners own an average of $100K worth each, and I doubt even my father, who was born in the early '30s, every had quite that much.

Assume, given the unwillingness of many gun owners to answer the questions of nosy, anonymous people making telephone and other surveys, that at least half the nation's households have a gun. With then nationwide sweep of shall or better issue concealed carry laws, now all but 7 states, making gun ownership significantly more useful, which is particularly important to an aging population, I'd be surprised if the fraction wasn't higher.

The number of permits issued has been astounding, 300,000 in Wisconsin since the law passed in 2011, 1 million in Texas, in these states generally 5-10% of the residents have one, and ~10 states don't require a permit or very soon won't (that number is changing very rapidly right now).
Single piston engine technology looks pretty promising as it has proven to be 30% more efficient than 4 piston combustible engine.

Downvoted because it's quite selfish to feel entitled to reply to an essay based entirely on its title - because I _did_ read the essay, and you're talking at a tangent about something that is interesting, but doesn't really belong in this thread.

Because you're talking about people lying about their actual morals, even to themselves - whereas the article is talking about how much people trust people with different stated moral positions.
You don't think it's racist that white people were given the loans that let them move to the suburbs and black people were denied those same loans and thus kept in projects?

Because redlining was often an explicitly racist choice.

https://en.wikipedia.org/wiki/Redlining

> In the United States, redlining is the practice of denying services, either directly or through selectively raising prices, to residents of certain areas based on the racial or ethnic makeups of those areas. While some of the most famous examples of redlining regard denying financial services such as banking or insurance,[2] other services such as health care [3] or even supermarkets,[4] can be denied to residents to carry out redlining.

> During the heyday of redlining, the areas most frequently discriminated against were black inner city neighborhoods. For example, in Atlanta in the 1980s, a Pulitzer Prize-winning series of articles by investigative-reporter Bill Dedman showed that banks would often lend to lower-income whites but not to middle- or upper-income blacks.
"Gun ownership: 88.8 per 100 people" -> 88.8 guns owned per 100 people.

I wouldn't normally object to a misplaced comma on HN, but in this case it is potentially very confusing. This sentence as written says that Prolog is not Turing complete, but actually it is; it's Datalog that is not Turing-complete. (I'm sure that was the intent.)

Ask HN: Best home office chair?
What home office chair do you use and what do you think works best? I am trying to find a new office chair for a standard height desk. I have an adjustable tall desk chair for my workbench (that is awesome) for electrical etc work, but need a good solid, reliable chair I can sit at for extended periods and do my work at a normal height desk. The tall chair just makes my back suck ass after an hour or so when I am solely working on the computer writing code, documents etc.
Back when seat belt laws where being introduced more than a few people complained that sometimes a person will die in a car accident because of the seat belt. Saner heads prevailed because the overall statistics showed much fewer deaths and injuries occur when using seat belts vs not using seat belts.

To me insisting on a 0% failure rate for a smart gun is very reminiscent of the mandatory seat belt arguments. Sure... sometimes a gun will fail and the owner end up injured/dead and that's pretty awful. However, if the overall the number of deaths and injuries has been reduced then those tragedies will have been "worth it".

It is irrational to insist on a 0% failure rate.

It is also probably irrational to insist on the same failure rate as existing guns. The correct measure is the deaths/injury rate.

Unfortunately the US doesn't seem to want to tackle the problem of gun deaths/injuries in any sort of scientific manner. There needs to be accurate and reliable data on gun ownership, gun usage (scared someone off), gun deaths, gun injuries. Solid data is the foundation of good policy... and preventing the gathering of good data is pretty telling.

And far too many vested interests are more than willing to mislead people. Specifically, the NRA's constant "confiscate our guns" rhetoric i pretty unconscionable... but folks seem to blithely accept this sort of misrepresentation.
There's a bit more to it than that; whatever the reasons (I forget), Colt lost the M16 contract to FNH in 1988 (but continued to make them for civilians, and in many years/all recent years/decades? at a high level of quality), and but essentially got it back in 1994 when the Army switched to the M4 carbine (the Marines stuck with their long barrel and therefore more effective M16s). Now they've lost M4 manufacturing exclusivity and for a while all contracts, and only recently won one of the new M4 full auto only, no 3 round burst variation contracts, presumably because they're desperate enough to bid really, really low.

On top of all the other problems, the company is now run by financial vultures who are bleeding it dry.

And, yeah, their flirtation with gun control did not go over well, I would never buy one from them after that, although their relative lack of quality in the category I might have otherwise (M1911s, which they were the original manufacturers of back in 1911) is the biggest reason.
I read http://articles.chicagotribune.com/1993-03-14/business/93031... . I wonder what would happen if they increased prices in response to backlogs.
Just FYI, you linked to a 3 piston engine (opposed pistons, which is a neat idea I hadn't heard of before), but think you may have dropped the wrong link.
It's not logically consistent. You're claiming that p implies not p
You're ignoring the lions share of zoning which is really about safety and conforming to standards. People like the money they spend to mean stability. And that means nice neighborhoods of houses don't want certain businesses because of trucks, unfamiliar traffic which equal danger to pedestrians. Some don't care about lawns or flags or color as much but it turns out the most insufferable people end up being drawn to the hoa boards.
> If she couldn't do the job then there is no reason to be discussing this

The creepy thought processes that go into calling it "graduation" (and throwing a party...) don't rely on any judgement about that employee's performance.
The constraint is to do the activity. One cannot do the activity by not doing it.
Does that 1.1 year average tenure reflect the fact that these companies are growing and have many new still-employed employees?
The video you link to doesn't describe a single piston engine, it describes a 2-stroke opposed piston engine. The animation shows 6 pistons in 3 cylinders.

I think we'll move fairly smoothly from ICEs to electric vehicles without significant commercialization of alternate designs.

Parasite companies in China think that they have an advantage by not having to follow US laws, but what they don't realize is that it can also work against them.
Background checks and waiting periods actually do make sense. People with a restraining order

The former is debatable (e.g. most handgun murders aren't committed when gun stores are even open, i.e. evening and night), and as far as I know the latter, when it's domestic violence, it's the law of the land everywhere. But that's very dangerous, since it's an easy way for the non-law abiding to strip a victim of protection when they most need it, and the threshold to get a restraining order, even a permanent one, is way too low.
That is simply not true. Maybe the latest and hipsteriest devices will all have those features, but the market is vast and caters to all sorts of humans and price points. You just have to care enough to make that choice as a consumer.
Japan, for one. At the end of WWII, the US Army of Occupation took away all the guns. The Government of Japan never removed restrictions on gun ownership.

In 2013, 12 people in Japan were killed by guns.

I'm approaching 35 years old, and HubSpot is a publicly traded company, ergo, a grown-ass company. If they need to cut labor costs, they do a layoff.

When I was 17 years old, I got fired without any warning from a mom-and-pop computer repair shop ($10 an hour, I think?) because I "talked too much" at the bench. Coincidentally, they had just hired a 15 year old to do the same job. I had also recently asked how i might go about getting a pay raise.

This is the kind of thing that a small business (which is constantly in crisis) does all the time. It's legal in "at will" states, but it isn't particularly fair.

Larger, publicly traded companies that aren't in crisis have no business acting like high school lunch tables.
What?? You can't possibly believe that the us has little mid mix density. Its all over cities. You're just trying to claim that some scheme would work awesome if only we allowed it. Come off it.
Chicago doesn't have a problem with gun violence due to Indiana's gun laws. It has a problem because of drug prohibition and the black market that has sprung up to meet the needs of drug users. You need to find the root cause (why violence is occurring) instead of looking at the symptoms (how the violence is occurring).
Oh come on, the claim is that safe (p) <-> !p, which is a bit different. Attack the actual claim.

You don't need to transport the driver for that, you can have workers residing in the cities to finish the work. But you still have to pay them, so you gain nothing at all. We already have quite a few more or less useful driving aids, I just don't get the obsession of making it fully autonomous. Legislations are lacking behind tech, ethics problems won't go away either, autonomous trucks could be prime target for hacking etc.
Thing is, Chicago has had a sky high crime and murder rate for a very long time, and went from no legal handgun ownership at all to it being allowed due to McDonald v. Chicago in 2010, took effect within a year or so, and now full and fairly administered shall issue in 2013.

Gun laws there are confounded by so many other factors in general crime and murder rates that I doubt much useful knowledge can be discerned until some number of years pass as the city returns to US norms of gun ownership and concealed carry.

I believe the parent is referring to the fact that the GI Bill and home loans for returning WW II veterans were written in such a way to systematically discriminate against blacks in this country. The explicit prohibitions you mention obviously existed at that time in the form of segregation, but whites were also given extra advantages by the racist way these programs were implemented. The extension of these benefits overlaps precisely with growth of sprawl, as whites used the increased purchasing power afforded to them by these programs to buy homes in the emerging suburbs (essentially following the incentive).

managers should be explicit about how an employee's job assignment is going to help develop his or her career

That's interesting. I've had a number of managers in my career and never, not even once, has one of them espoused anything resembling such a position. It's always what can the employee do for the company, not what's mutually beneficial.
From my perspective, the best antidote is to always use logical, intellectual responses to problems, rather than an emotional response.

Let me guess: engineer?

There's absolutely a personality type that prefers to solve all problems with logic and clear thinking, which is a very good thing when you're dealing with engineering problems.

When you're dealing with people, though, that kind of response can be actively counterproductive. Anyone who's had a significant other "vent" and respond negatively when you try to turn to problem solving will probably recognize this dynamic.

Not all people and all problems are amenable to "logical" solutions.

Controlling negative emotions is a very good thing. But there are many ways to achieve that. Turning to rational problem solving is just one mental tool, but it's not fit for all occasions.
"chased" is a strange choice of words here.

Nassim Taleb's "How to Legally Own Another Person" or David Graeber's book The Utopia of Rules and now this article could be categorized as welcome to working in a bureaucracy. I grew up in corporate land and I am use to ex PGW, Deloitte, or McKinsey employees being called alumni. So it makes sense as the current generation of tech companies mature they become more bureaucratic. Hopefully this means we will see a new batch of startups hit the scene soon!
That was from the developers mailing list. I think the only optimization they're doing is for FOR statements, where you know the bounds on a loop variable at loop start. This is a big win for loops that iterate over an array and do something trivial, like setting the array elements to 0. Subscript check performance is mostly an inner-loop problem.

> On today's Earth, this group of people is vastly smaller than the number of people who can carry out cash transactions in person, not just because of poor adoption, but because of a fundamental UX problem.

Yet. There is no reason why cant UX be n00b-friendly or may be it already is. Low adaption is probably due to either people are unaware or there is lot mis-information. Anycase, adoption is steadly increasing.

In my ZIP we're averaging just over 1 home invasion per day for 2016. Three people have been shot and killed. In the next ZIP over a wealthy nationally-recognized clothing CEO fatally shot someone breaking into his home last month.
Without wishing to comment on what is or isn't feasible now or in the future, I'd approach the technical requirements similarly to self-driving cars. They simply need to crash less often than a human driver. They don't need to be completely infallible, though for emotional reasons they need to crash significantly less often than humans.

Similarly, a gun would need to have a failure rate somewhere in the order of 1% of the typical misfire rate. E.g., if a particular gun & ammunition pairing misfires 1 time out of 1,000 then the security system must fail no more than 1 in 100,000 times or thereabouts.

At that point, any misfire due to the security system would be indistinguishable from a misfire that would have happened anyway.

A 1% increase in misfires would not equate to a 1% increase in unintentional deaths, but a viable safety system would significantly decrease them. In fact, it might be possible to mathematically derive a much higher break-even point, but I daresay that would not work out well politically.

This is silly. USA is sprawled (and has been since before WW II) because the USA has far more territory (and far more territory per person) than any other temperate-region nation.

Heh.

But seriously, absent a population of brown bears (e.g. the Grisly), I'm not sure it's that great of a problem. And many people simply don't care about the occasional child, jogger, etc. killed by a mountain lion, bear, whatever.

I felt like most of my managers at Google tried pretty hard at this. We certainly did have conversations about what I wanted long-term within my career and how that might best be accomplished within the organization.
