Citizen Scientists Develop Eye Drops That Provide Night Vision 65

rtoz writes: A group of scientists in California have successfully created eye drops that temporarily enable night vision. They use mixture of insulin and a chemical known as Chlorin e6 (Ce6) to enable the user to view objects clearly in darkness up to 50 meters away. Ce6 is found in some deep-sea fish and often used to treat night blindness. The solution starts to work within an hour of being applied to the user's eyes, and lasts for several hours afterward. The test subject's eyesight returned to normal the next day. The organization Science for the Masses has released a paper detailing the experiment on their website.

Having fun isn't necessarily stupid. Having fun with flamboyantly dangerous things isn't necessarily stupid. It's endangering unwilling bystanders that's stupid.

Some people like to build and shoot powerful crossbows, or even replicas of medieval siege weapons. These are extremely dangerous and useless things. The dangerous power of a trebuchet to throw an upright piano 150 yards is part of the charm.

But a trebuchet is something that takes certain amount of thought and sacrifice to obtain and use. This flamethrower thing is more like a powerful handgun. There's been a recent fad for ridiculously overpowered handguns, which pack superfluously fatal power into a convenient, affordable form factor. The recent brouhaha over "armor piercing" ammunition was a side effect of a manufacturer selling a cut-down semi-automatic carbine as a "handgun", even though if you look at videos of people using them they're obviously terrible as handguns. This raised the question of whether 5.56 NATO ammunition should be regulated as "handgun ammunition", and in the end I think the decision not to was reasonablee. These aren't cop-killing or military handguns. They're extremely dangerous toys designed to get your rocks off.

There are some who'd say that because these guns are dangerous and impractical they should be banned. But I don't agree. "Impractical" isn't the same as "useless" because getting your rocks off is a legitimate use for a thing. I think people should be able to enjoy their ridiculous firearms as long as they do it at some kind of appropriate range. I also think there's a real danger though from stupid people who will go plinking in the woods with the things like they were BB guns.

That's really the only problem I have with this flamethrower, whether it's gold, chrome, or gunmetal gray. Any idiot can buy one, but it'd take someone reasonably intelligent and determined to find a place where it can be used safely. I'm not against people buying them, but I am for coming down hard on people who use them where they're a danger or public nuisance.

Well, in the end you have to ask "did he get away with it?". Or, given that he turned himself in later, "did he have some purpose in escaping that he fulfilled?"

Intelligence is a multi-dimensional phenomenon. It includes things like thinking through unintended consequences before acting that quite clever people are sometimes bad at.

If that's all the variable is used for, won't the compiler optimize it out of existence anyway? Or is that too fancy yet?

I think a lot of people don't really understand how the compiler actually works. Not even at a basic level.

Well, no, I don't. That's why I asked. It sounds like the answer to my question is yes?

But as for taking production back to Wolfsberg, last I checked there were still lots of VWs made in Mexico.

Right. Don't buy them. They specifically moved the Golf back to Wolfsberg. Be careful, though, because I think they moved it back to Mexico more recently. You can get e.g. a "VAG VIN Decoder" app for Android, or just memorize which place in the VIN to look at and a handful of plant codes. Then you'll know precisely where the vehicle was produced.

If adding a variable aids readability, add the fucking variable! Shove all the results into a meaningful, readable variable name and then shove *that* into your function argument, not some long series of nested function. It's not the 90s. You don't have to save memory! Memory is there to make your code readable. Use it!

I got my job just because the company I work for had over twenty developers that were all male, and it looked bad on their EEO report.

Not because you were the most qualified applicant? That means the company you work for hired you not because they should have, but because they were strong-armed into it. In fact, they should not have had to have hired you, they should have been able to hire the best-qualified applicant.

The reality is that society needs children.

The reality is that you are asking employers to pay for that, but making children isn't their business. If society needs children, then society should pay for children, through income redistribution. Oh wait, guess what? We already give people a tax break for having children. I've known people who made more than me but paid no taxes because of their children. Now you want employers to pay again?

Of course the rules should apply equally to both genders. You could argue that people who don't have kids should get more time off,

Or you could argue that people who do have kids don't deserve to get paid for their time off. A person who doesn't have kids is worth more to their employer. If people can't afford to survive while they have kids (they can) and we need more people (we don't) then it would be worth it to pay people to have kids. Big problem with that is there are too many humans on this planet already, at least while we operate in our current mode. You want more people made, but that's the opposite of what we need.

If I want a car assembled correctly, I buy one which was put together in Germany

You mean like all those VWs built in Mexico?

No, completely unlike those VWs built in Mexico, which are built like shit. The only thing more embarrassing to my heritage than how shit UAW puts together cars is how shit Mexico puts together cars. It's interesting that you mention Volkswagen because Mexicans are known to be particularly bad at that. When VW brought USDM Golf production to Mexico, reliability plummeted. When they took production back to Wolfsberg, it came right back up to the German standards that we know and love.

Anyone who buys a VW built in Mexico is a moron. All of my imports to date have been built in their designing nation, and came over here on a boat fully assembled. Started with imports with a 240SX, then I had an Impreza GC5, couple of 300SDs (still have one) and an A8. That last has electrical problems but the mechanicals are good, anyway. And there's the rub with VW; their electrical is a bit garbage, even out of Germany.

Were it an application for an IT security role, in the style of those challenges Google and GCHQ have used, then you might have a point and they might have a rather lame excuse. Sadly, this is an application for security of the knuckle dragging variety, and to make matters worse the application process has also been shown to be completely unfit for purpose as just about anyone can successfully apply for a license, including those who should absolutely be prevented from doing so.

When you've got a government department that can't even fulfill do the non-IT related role that it's supposed to do, why am I not surprised that it's also completely incompetent at something it's not - viz managing the procurement of what should be a simple web form process and DB backend?
