I don't know how you arrived at that figure. The number that I find in the report that you link to is 47 140 valid defensive uses per year. (235 700 in 5 years.)

The number of times a firearm is used in commiting a crime is not in that report. What I could find was:
Number of murders involving a fierarm, according to the FBI: about 12 000 per year
Number of robberies involving a fierarm, according to the FBI: about 170 000 per year
I didn't bother looking up the numbers for things like manslaughter and aggrevated assault, but I'm sure it's a lot.

I think you misunderstood me. When I said "the people" I did not mean the Ugandan people. I have nothing against the the Ugandan people, (nor Christians or any other demographic).

By "people" I meant "persons" i.e. the relatively few individuals (American and British as well as Ugandan) who actively advocated for a death penalty for homosexuality for the stated reason that it says so in their Bible.

Yes, the vast majority of Christians condemn these extremists just as the vast majority of Muslims condemn theirs, but the "my team is better than theirs because look what they did" argument does not hold. All large population groups have the same fraction of assholes.

The law is still there. The fact that it was ruled invalid by the court does not make the people who fought to put it in place (some of whom were American) any less despicable.

My point, though, is that there are unevolved people of every religious (and non-religious) orientation. Saying that one religion is more evolved than another just because the worst of the fundamentalists have less political power is a non sequitur.

will be the new level of warfare.

Yes, and not in a good way.

It used to be the case that you needed experienced, diciplined soldiers to make snipers. If you tried to fight a proxy war by arming insurgents the way the U.S. armed the Mujahideen (al Quaeda), or the way Russia is arming Ukranian separatists, then you got a pretty inefficient force that could only win by war of attrition.

These new weapons will make it much easier for anyone with money (like the IS) to recruit people out of the slums and quickly turn them into effective fighting units.

Also it will increase the efficiency of child soliders, and therfore lead to more recruitment.

It seems to me that Verison's problem is on the marketing side. Their technical implementation is correct.

This is basic QoS. For a simplified example, let's assume there are only two users (but the network is still congested). One is trying to download a fix amount of data, i.e. watch a certain number of YouTube videos. Let's call her the "limited" user. The other is trying to download as many linux-distribution isos as she possibly can. Let's call her the "unlimited" user. (We assume that the carrier can guess which user is which, based in historical bandwidth use.)

If the carrier throttles both users equally - what some would consider the "fair" solution - then the limited user will have to wait while her videos buffer (but we will assume that she still watches the number of videos that she had decided on). The amount of data that the unlimited user can download equals total network capacity minus the size of the YouTube videos.

If the carrier only throttles the unlimited user, then the limited user gets a better experience, but still watches the same number of videos, i.e. downloads the same amount of data during the period of the congestion. The amount of data that the unlimited user can download still equals total network capacity minus the size of the videos, so she doesn't actually get any negative effect from the "unfair" throttling.

(The above reasoning holds even if the unlimited user is also watching video, if we assume that she has a large enough buffer. But if both users are doing video conferencing, then it would be better to throttle both equally.)

Of course, the best solution would be to upgrade the network to 4G, and this is what the FCC should force the providers to do.

I've found it funny when I've made arguments about Google's ad scanning being something I didn't like, and people always came back with "but it's 100% automated and completely anonymous - no human ever looks at your mail".

I think that argument just got settled with this story - and I won.

No, you did not. This does not condradict Google's claim that no human ever looks at your email. The only thing that has changed is that in addition to being scanned for spam and viruses, attachements are now also being checked against a database of known child porn.

If someone won the lottery, was struck by lightning and hit by a meteor on the same day, that would be newsworthy. The likelihood of finding an incidental SHA512 collision is much, much lower than that even if you dedicate every computer on the planet to the search.

So yeah, it would be worthy of publication, and it would indicate that there is a flaw in the hashing algorithm.

So what? It's sports. Entertainment. For fun.

If there were scores of athletes showing up with amputated limbs, winning everything and distroting the rankings, then this discussion might be worth having. But these are the statistics so far:

    Long jump competitions won by peoploe without prosthetic limbs: A shitload
    Long jump competitions won by peoploe with prosthetic limbs: One

You might argue that he is getting an unfairly large share of the prize money, thus hurting the other athletes, but it is probably the other way around. He's drawing more attention to the sport, hence bringing in more sponsor money, to the benefit of all.

The main way to make datacenters environmentally friendly is to build them near windfarms, and to build more capacity than you need. Then process data in the center where electricity is the cheapest, i.e. where there is an excess of wind at the moment. This increases the profitability of windfarms and leads to more investment.

are you five?

As I wrote in the first sentence of the post you are replying to, I worked for seven years in research and development on fuel cell vehicles. You do the math.

Have you ever even driven a car or owned one?

I've driven a fair number of different vehicles, including prototype fuel cell cars.

You seem hot have no clue about weighing pros and cons or understanding the challenges new tech must overcome.

Unlike you?

You know what? nobody gives a crap! the three important things for hydrogen stations are cost per mile, fuel source, and GHGs. nobody cares about mathematical efficiencies.

Efficiency is the most important factor in determining cost per mile. A car that requires four times as much electricity will have approximately four times the cost per mile. It will also cause four times the green-house gas emissions, assuming that the source of the electricity is the same.

(Protip: If you want to be taken seriously in any kind of scientific argument - Don't say that "nobody cares about mathematical ..." Scientists do care about math.)

you know what people do care about? range and convenience time. you know what's not convenient? recharging for four hours every 20 mins!

Four hours charging for every 20 minutes of driving was over twenty years ago. Today, most electric cars have a range that exceeds what their owners drive on an average day. This means the owner spends 10 seconds per day (one minute per week, assuming that he has Sundays off) plugging in the car when he gets home. The average non-electric car owner spends much more time than that filling up his car. A fuel cell car owner would spend even more time, because hydrogen cannot be transferred as quickly from one tank to another as liquids can.
