Comment Re:Why just guns? (Score 1) 264

If a bad guy jumps you with a knife, pulling your gun out is too slow.

If a bad guy "jumps you" then unless you're Aikido dude or what have you, you're probably already fucked no matter how you intend to defend yourself. Initiative is massively important, and I don't mean that in a dungeons and dragons kind of way. Often, the first shot decides the fight.

On the other hand, most people aren't carrying around long sheathed knives, if the knife is big enough to need a weapon to defend against it then it's probably a folder and you very much can draw a gun, point it, and shoot in about the same kind of time.

Guns work great at a moderate distance. Three meters. If you can keep three meters and draw a firearm against a melee-armed man, you have control. At shorter distance, you have liability.

At a shorter distance, guns are still massively deadly. Point blank is scary for a reason. I don't want to be involved in a close-quarters fight with someone with any kind of weapon. The best defense is to be somewhere else. Yeah, blaming the victim, but if you have the opportunity to be somewhere [relatively] nonviolent, take that option.

Microphone will pick up *a* bang, and thus will give an information when *some* gun was fired in the vicinity of the police.
It could be any gun on the scene

Today, the US military fields equipment which can tell where a gunshot occurred, and what kind of firearm was responsible, and what kind of ammunition it uses. Granted, it must require training, but since cops have to qualify with their sidearm that's an ideal time. Let's get some of those into the field rather than MRAPs.

Except, being able to create sellable fuel from nothing is a killer business. Nobody would say "let's NOT take over the world's fuel production and make trillions of dollars from our patent; let's instead sit on it, and buy all our fuel from elsewhere". So logic tells us that there must be something wrong with the product that means it fundamentally doesn't make a profit versus digging oil up.

Okay, smart guy, tell us what the problem is. Gevo doesn't see a problem.

If someone was able to make bacteria that could, given sunlight, split water, it would spark a hydrogen economy revolution.

We already have bacteria which can, given any organic matter, split it into butanol (a 1:1 replacement for gasoline) as well as acetone (an industrial solvent, which burns clean and can be used to alter the octane ratio of the gasoline replacement) and ethanol ('nuff said.) Practical commercial exploitation was worked out at a public university and therefore partially with public funds, but the patents are owned by Butamax, a shell company owned by GE and DuPont. They have sued Gevo to actually prevent them from producing and selling fuel to the public, something in which Butamax apparently has no interest. They've been sitting on the technology for years.

The truth is that if someone did come up with such a bacteria, a patent would be assigned to a corporation by hook or by crook, and it would either be exploited or be buried to preserve profits for other industries until such a time as those profits become harder to come by. But the already-inconceivably-wealthy seem determined to ride this pale horse until they run it down... Right down our throats, until we choke.

I've got five Android 4.x devices that run Netflix and Hulu and everything just fine, and Amazon STILL won't let me install their fucking app on ANY OF THEM. So much for 'releasing' it.

time to do some hacking. you can diddle your uh, shit, this post would be a lot cooler if I could remember what the file was called... [googling] ah yes, /system/build.prop. There are various build.prop editors, and you can actually change your phone model there.

There might even be an Xposed module which will let you lie to apps about what kind of device they're running on, but I haven't looked into that at all. Just musing.

Not increased government accountability or transparency, but a hellbent determination to make sure they will never be caught with their pants down again. Sigh.

And that's why this government will fail, regardless of what We The People actually do. It will become too paranoid to function effectively. You don't think the most creative minds go to work for government, do you?

Comment Re:And low-emission transport trucks, too (Score 1) 491

Here's how it works. Deisel tends to make a lot more particulate pollution, but a lot less gas pollution (CO, CO2, etc).

Nope. As it turns out, gasoline-burning engines emit more soot than previously believed, as the measuring technique formerly used was incapable of detecting the finest soot particles. The particular irony of this is that the smaller the particulate matter, generally the more hazardous to one's health. PM2.5 (particulates below 2.5 microns in size) are considered to be the most hazardous, largely because they're smaller than cilia. This means that it's difficult for you to expel them from your lungs. Gasoline engines produce more PM2.5 than diesels do! They produce about the same amount of soot, but the soot they do produce is more dangerous.

So, it doesn't make as much pollution, but the pollution it does make is worse for the people making the pollution, since it all stays local, and we deal with particulate pollution worse than stuff like CO and CO2. Personally I'm fine with this. I hate the view of "well it's better for the environment because it doesn't affect me" BS that EV advocates tout. They don't see the damage created by making batteries, so it's "clean".

Supposedly, a great deal of the pollution involved is actually in shipping, much of which goes away when the gigafactory gets built.

has anything really changed re: tesla on the actual net pollution front?

If nothing has changed, then EVs are still cleaner than gasoline cars by some 40%, so that's still a win.

If we used technology proven by the USDoE at Sandia NREL in the 1980s, we could be capturing CO2 emissions from those plants and using them to grow algae as a biodiesel feedstock — improving yields by as much as 80%. So while EVs are only part of a comprehensive attempt to improve transportation efficiency, they're a completely valid part, provided that we do the other things that we need to do — which we know how to do already. We're simply not doing them, because money.

Sure, when the reactor in question is operated using 1950s-era dials and valves and shit! But you'll have to do more to convince me that what you say still holds true today, with modern computer control.

The problem becomes that you don't want it anywhere near a port in case it goes wrong. Sure, the USN claims they've never lost one of their reactors, let's say that's true for just a moment. Russia has lost some. It's not outside the realm of possibility. And while a computer can in theory substitute for a highly trained crew, in practice uh no, and also no. Not in this case. So basically, it's a useless idea.

We need future-technology electric power storage to really solve this problem, or future-tech materials technology so that we could for example build submerged tube trains, or a chain that would pull container ships along, etc etc. Barring that, we could be producing biodiesel from algae and using that to run ships. NOx goes up a bit, CO2 goes way down, so does soot — as compared to #2 diesel, let alone marine diesel, double extra let alone bunker fuel.
