As with most things, follow the money. Who benefits the most when the public is frightened of gun violence (and also being told to arm themselves)?

Similarly, war deaths (as a portion of total death) have been decreasing incredibly. Yet, globally we keep increasing our spending on military. And, the public is frightened of war. Some would say that the spending on military has been the major deterrent to war. But, studies show the decrease is more related to rises in democracy and global trade.

This code is beautiful, but it's also busted [1] -- albeit only for extraordinarily pathological input. As to whether this ultimately dents its beauty is up to the beholder, presumably; for me personally, I confess to suffer from a utilitarian sense of beauty when it comes to software -- for me, broken code can't achieve absolute beauty.

It's also worth noting that while blunt objects such as hammers and baseball bats find uses in construction and non-violent sports, guns do not necessarily share such innocent use cases. Sport shooting is the major exemption (I'm quite a fan, myself) but at the end of the day guns are designed to put holes (some messier than others) in objects very far away. When a gun is pointed at a living organism and the trigger is pulled, its chances of survival plummet.
That's down from something like 8/100mmVMT at the beginning of the data set.
If you're taking pictures of people, you end up having to take dozens and dozens of the same shot because people's expressions change so much. When you get a chance to filter them - it's too late to take the shot again - even if that's just minutes later. Of course you could delete the rejects - but it hardly seems worth the time.

Also, auto bracketing for HDR (3 pictures per shot normally), RAW+JPEG and continuous shot modes all tend to generate a lot to store.

What troubles me most about the title "Data Scientist" is that it really means "Statistician" or "Statistical Analyst". There are so many interesting things you can do with lots of data, stats is but one of them. What do we call people who are good at some of the other disciplines?

I've spent bits of my career working with fairly large data sets at one time or another, and providing discovery, insight and analytic tools into that data, but very little of it seems to have anything remotely to do with what the job descriptions for "Data Scientist" are asking for.

Consider this, building a very large graph of the internet, then using various models on that graph to find unique and actionable insights: such as finding routing bottlenecks for a video delivery service, involves lots of data, lots of scientific like exploration, yet isn't a "data scientist" job by the job reqs.

How about this, building a text parser that can finely categorize and make recommendations for a research organization based on millions of grant proposals, all categorized into various "mission silos" that research organization is built around. Not a "data scientist" job.

Analyze multi-lingual news stories to build a real-time alert system for conflict analysts. Not a "data scientist" job.

Building a tool that can scan multi-spectral aerial imagery and automatically extrapolate man-made structures from natural, catalog all of the different vehicle makes and models, and generate a predictive model of commuting patterns, or make recommendations for housing development based on perceived socio-economic conditions? Not a data-scientist job.

Collecting information on who propositions who from a dating web site, normalizing the data for population and writing a report on the findings? That's a "data scientist's" job.

It's not that that kind of work isn't valuable, only that there are so many other kinds of things that involve what might intuitively be called "data science" that calling just the one discipline "data science" is doing a disservice to what should be an amazing discipline -- part Computer Scientist, Part Analyst.
It appears that gun homicide rate increased under Bush Sr. (~5.6 => 7.0) and Jr.(3.8 => 4.0), and declined under Reagan(6.6 => 5.6), Clinton (7.0 => 3.8) and Obama (4.0 =>3.6).

Numbers are in death/100,000 people, (+/-0.1 because they were read from the graph[0]).

A t-test on the yearly rate of change, yields a p-value of 0.002. (in Excel =T.TEST(A1:A12, B1:B14,1,3)).

Did the Bush have a peculiar approach regarding crime fighting?

Rifles (especially AK47s) are very popular with gangs for drive by shootings.
Nobody seems to mention the reason I think accounts for a good deal of the drop, which is simply the perception that you're going to get caught is much higher. Up until the mid 90's there wasn't even DNA analysis. The world was a much simpler place, no cameras everywhere, cell phones, internet, and a myriad of other ways to be tracked. The rise of technology in law enforcement coupled with the non stop blasting of crime shows depicting criminals getting caught (e.g. CSI) has greatly increased the perception that you will not get away with murder. Today most sane people at least view it as something extremely risky and hard to get away with. Even to the destitute gun crime is not a very attractive option these days, whereas 20+ years ago it wasn't nearly as big a deal. Of course there's a handful of other factors, but I think the perceived likelihood of being caught is probably the most significant.
Can be read as, "I agree with this."
No, because he compared percentages. If gun crime has fallen by 50% and overall crime by 72%, that means non-gun crime has fallen by more than 72%, i.e. much faster than gun crime. Or to put it another way, more crime is being committed with guns than before. Reality's well-known liberal bias strikes again.

It would be really cool of this post discussion talked about technical causes and solutions for the impedance mismatch between reality and perception and masuremep, and not rehashing the arguments about guns.
Apart from some specialised scenarios (e.g. direct interfacing with directly attached devices) then web applications are clearly the way to go for newly written applications. However, I would be very reluctant to describe anything non-Web as "legacy" - enterprises will happily (and rightly) still buy desktop applications if they are the best tool for the job - and these need Citrix or Terminal Services.
Smugmug.com is what you are looking for.

For $5 per month,($60 per year for a Power account), you get unlimited storage for photos and video. With third party apps -- SmugFolio on Android. I'm sure there is a similar if not better app for iOS -- you can manage your web-based portfolio using your phone, automatically upload photos to your account, and rate them.
You also get access to great printing and other services.

Problem solved.
Actually I forget where I read it but there is a hypothesis going around that the overall crime reduction has to do more with liberalization of things like birth control and access to abortion options.

At work at the moment and don't have time to pull up the details until tonight, but the examples given say of romania where none of the above is legally available still has a high crime rate. The general gist of things are that having to keep around kids a parent doesn't want tends to lead to bad outcomes for the children in life. Its much more complex than that and obviously we can't run randomized trials across multiple generations to validate things (not that it would even be ethical), but its interesting nonetheless.

> At a generous 5 MB per photo, that's 24,000 photos. You would have to take 65 photos, every day, for a year straight to reach those numbers. That's 1 photo every 15 minutes of your waking life for a year (assuming 8 hours sleep).

Is that generous? A RAW file from my SLR is about 20 MBytes. Many SLR's have larger RAW files. But using my "conservative" estimate that's 16 photos a day.

Considering the average photographer can snap 10 photos in about 3 seconds during a photo shoot this seems very reasonable to me.
Yah, I guess you cannot provide 24/7 support anyway especially if you have customers in different timezones as you're going to have to sleep at some point.

I was thinking more in terms of "My server died and my business is burning because of something I could fix in 10 minutes with SSH" or "my main client had their server hacked by a 0 day RoR vulnerability" and I'm stuck here filling in TPS reports until 5.

I suppose some level of monitoring and a deposit + SLA left with someone you trust to resolve first line issues could go a long way.

Many would be better off not watching any news or reading any newspapers. Even relying on the Internet makes things tough since there's a firehose of data, and this leads to confirmation bias having a huge affect.
To the OP: the table looks really nice, but the article could have more "meat". Maybe you were afraid of retreading the material, but one short paragraph on each of the AARRR metrics and how the SaaS metrics affect them would make this more useful as a reference for the average bootstrapper.

Also think how you can turn this into a series instead of a collection of articles. One obvious choice, since you are writing about churn, is to go over each of those "circles". See one good example of creating a series to build a mailing list here: http://www.trevormckendrick.com/

Freakonomics says this.
I wonder if the increase in available distractions, such as video games, has something to do with it.

And I don't know the name of the theory, but stats don't really relate well to certain events, such as taking a bullet. If took_a_bullet = false, then are you really thinking about the odds? If took_a_bullet = true, then you've got bigger problems than becoming a statistic.
Thanks for this reply - I didn't have to write it myself. Well said.
Well.. that's not to say a rate of 3.2 is a good rate. The U.S. still is far above most western countries, which typically have something like 0.x or even 0.0x homicides per 100.000.

It means that there is no defined limit (and thus, no accruing, and nothing to pay out if unused when you leave) of vacation hours. You still have to get your assigned work done.

What that means in practice will depend on the particular environment. It can mean that you have less stress over managing leave balances, it can mean that, because of workload, you can in practice neither take vacation nor be later compensated for not being able to take it.
In deed, you remind me of Solon's warning. Perhaps the better way to put it is he's attacking one heck of a problem - and with the right detachment to both industry and academia - so the minimum is based more on the quality of problems than the individual ( as unique as that is in this particular case ).

But yes, being an entrepreneur is an added layer, as you've to learn to arrange people to attain a larger goal than just research.

And he shows signs of that even on the jobs page while avoiding the broken method of interviewing that is oft practiced, he's almost defining a boundary for relatively high signal from the applicants.

His fluid approach is reminiscent of the caper that the Google guys pulled at Stanford.. and as it turns out, I think he also got funded by Larry.
Self-killing is really a different social policy concerns from other-killing.
"What is the estimated number of people who have been significantly wronged by abusive wiretapping, and how does it compare to the number of criminals arrested and crimes averted by wiretapping?"

When selling or even possessing recreational drugs is a crime, and when search and arrest warrants are routinely served by paramilitary teams, talk of "the number of criminals arrested" is meaningless. America's legal system has become so broad that anyone can be arrested, and the obvious result of that has been that America has the largest prison population of any country in the world by an order of magnitude.

Law enforcement is not about catching all criminals, nor is it about preventing all crimes. The power we give to law enforcement must be balanced with the need to preserve a free society. The more power the police are given, the easier it is to enforce oppressive laws, and by extension to create oppressive laws in the first place. We limit the use of police power with complicated procedures and requirements for that very reason.

It is also the case that expanded law enforcement powers tend to disproportionately impact certain minorities due to the disproportionate attention given to those communities by the police. As things are now, there are black communities in America where a quarter of the men are in prison or have been imprisoned. It is a near-certainty that if the FBI's proposal becomes law, the new wiretapping power will be disproportionately applied to already-oppressed minorities.

"I understand that the situation is different in authoritarian countries."

The sad truth is that right now, nobody can truly know that they have never committed a felony. As an example, large numbers of Virginians naively believed that living with their boyfriend/girlfriend was perfectly legal; yet until a few weeks ago, it was a crime:

http://www.huffingtonpost.com/2013/02/03/virginia-weird-laws...

It is by the selective application of these surprise laws that the US government is able to achieve an effect similar to that of a authoritarian government. Obscure laws have been used to attack protesters in the past:

http://www.firstamendmentcenter.org/prosecutors-can-charge-g...

http://online.wsj.com/article/SB1000142405311190419460457658...

Expanded police power means an expanded ability to engage in these sorts of tactics. It is not a stretch to say that if the police can more easily wiretap people, they can more easily identify protesters planning to wear masks or board ships. Perhaps some other obscure law will be invoked next time -- there are so many laws that the Federal government is not even able to count them all.
It is possible, and likely will happen. However, the OP is completely relevant.
Well back in 1993, almost 49% of households had a gun. Today the number is 32%. That alone is a 35% drop in gun ownership.

There are so many other factors that could play a role here. And none of them negate the need for common sense gun regulations and re-funding research on both gun and non-gun violence.

Certainly a good first step into graphics programming in functional languages but i doubt we will ever see something like Unreal Engine 4 written in Haskell.

Some may call me crazy, but I have a hunch that the decline in gun homicide, and crime in general, is related to gaming.

There is frequently a claim that it's the FPS and other violent games that trigger mass shootings. Although I believe that there is an negative effect, I also believe that that negative effect is essentially all but negated by other outcome positive effects of gaming. I feel like there might be net positive outcomes related to those who would in the past have been the types who felt the need to enforce their ego through violence, posturing, and domination. Additionally, because those types of people / kids would then also not have come in contact with "mentors" who would groom them, there could also be a cycle-interrupting process going on here.
Similar policies have worked brilliantly with alcohol and tobacco, or so I hear.
93' was gangster. I was a teenager around then and a lot of people were gangbanging at the time. Most of those people realized that they didn't want to go to prison for murder.
If you sign an employee agreement that says, "we own all of IP you produce past, present and future," then it's obviously enforceable, right?
>People might be a little more serious about locking up their guns and not letting their kids play with them.

People are serious about not letting their kids play with guns.

You make it seem like this happens a lot.

In 2007 there were 122 children killed accidentally by firearm.

Sugar breakfast cereal is a far greater danger to kids than guns.
I agree. The article was meant to be a high-level introduction to the phenomenon for the Dutch audience. They missed that wave. I had know idea it was going to end up here:) Apparently a controversial title can still trigger lingering emotions:) Most people still don't seem to have a clue what is possible, though.

IMO something is accelerating/changing and we hit an inflection point. It does help to give it a denominator. It's human, not just marketing. I'm sure one time people thought compsci and software engineering were redundant or pretentious. I'm still ambivalent about the name data scientist.

Agreed. There aren't any comments on this article that I couldn't have read on reddit. Topics like this will always generate a lot of comments and discussion since it's very easy to have an opinion on it (vs more technical topics).
Of course they're unaware. It's harder to keep fear alive when information like this gets out.

Both sides know this. But each side is convinced that it benefits more from a fearful populace than an unafraid populace, and that the reverse is true for its opposition. And so the fearmongering continues.
To be fair, I am not sure if anyone would try posting 6 billion gold onto a PTR equivalent of the RMAH or whether the RMAH is even available on the PTR, which might explain why it wasn't tested.

I need to underline that he throws video in like it's nothing.

Sure, just for images without responsibility of 6-8 9's for peoples' treasured decade of photos, you can approach the price. I believe Imgur also has, even pro accounts, a 5MB limit on file size and that brings a set of efficiencies on resources. Fine for pictures, trouble for video.

When 1-10 million people are uploading/downloading 200MB/min for video @ maybe 1MB/sec?, storage stops being the most painful problem.

This would be something of a netflix scale problem, but without some set of minimal control about formats, dynamic content throttling, etc.
Why? It's just a matter of scale. Until very recently, Romania's currency was such that most middle-class families had 8-10 digits in their bank account at any given moment, and the economy is relatively healthy.

Good items sell for hundreds of millions. The number of zeroes doesn't matter, as long as the balance between items and monetary value is stable.
I remember a similar bug in the original Asherons Call (amazingly, still running with regular content updates!). Three or four years in, they added a new, very expensive object to the game (a "Pyreal Scarab" for anyone who cares). It cost a lot, so the idea was that people wouldn't be (at that point in the economy) buying many.

Now, in Asheron's Call, the world is huge. There are hundreds, if not thousands of vendors. And three of these vendors were set to sell their goods in stacks of up to 1000. Unfortunately, Cost of Pyreal Scrab * 1000 > 2^31, which wrapped. I can't remember if you either just got the goods for free (which you then sold back for huge profit), or if you actually got paid to take these things. Either way, overnight, the economy was destroyed. The entire game state had to be reset from backups; a dreaded rollback. Worse, the developer took a few days to do this.

Trust me, out of all the customers whose data you don't want to muss with, it's hardcore MMORPG players. Even though I was just a player, I can still remember the outrage all these years later. It taught me to always use appropriate types for objects with "value", and I've never accidentally used signed or floating point storage for currency again.
I wasn't aware of that. To be sincere, I also made the mistake of looking too close home. I was mostly talking about the non-English-speaking 'western hemisphere'.
Kingdom of Loathing had an integer overflow bug way back in 2004. It let players set their currency (in this case: meat) to the max value of a 64-bit integer. The game spent the next several months setting up meatsinks in an attempt to reduce the amount of meat in circulation.
