There is no legitimate use.

DPSS pump for UV lasers for fine-feature photolithography.

Mount in x/y plotter for cnc marking of wood or papercutting.

Drilling vias in polyimide for flex PCB's.

Pump for adjustable-wavelength dye laser.

I could probably come up with another 20 legitimate uses if I felt like it, but I just mentioned those because I've used 1-10W lasers for all those things.

but none of the uses you listed would involve a handheld 1W laser. That's the question. What would be a legitimate use of a handheld 1W laser?

Nobody seems to have mentioned what this fuel will give off when it is burned. If it still produces nasty greenhouse gases then it doesn't solve any problem that matters.

But if it uses organic matter from plants, those plants have already pulled carbon dioxide from the atmosphere, making it "carbon-neutral".

Poor guy. I guess sooner or later he's going to have to learn how to manage his memory and understand how the underlying physical hardware works. That must be a real toughie for anyone who learned to "program" in the Java/C# world.

Yeah, clearly PHK doesn't knows anything about memory allocation. (Except for the malloc library he wrote for FreeBSD...)

Maybe he should RTFM.

I don't have a FreeBSD system at hand, but I wouldn't be surprised if the malloc page was written by PHK.

hehe, WTFM :-D

Postgres doesn't have a "just give me a damn database" option

$ createdb myDBName

Now I have a new db. Was that really hard? Well, it only works because I am a valid PostgreSQL user. For completeness, I'd also need to do something like:

$ sudo -u postgresql createuser theraven

Actually, the sudo part of this is not required if I am a user that is allowed to create users, but assuming a fresh PostgreSQL install from a standard package.

I agree. The createdb and createuser command line tools for PostgreSQL make that super easy.

Comment dimples (Score 1) 897

Mythbusters added dimples (like on a golf ball) to a car and got a rather noticeable (iirc, about 10%) improvement in gas mileage. I would be interested to see if that could be implemented on a production car.

Another useful geeky aid organization: Télécoms sans frontières

Er, no.

Don't get me wrong, the work they do is great, but Télécoms sans frontières is a first-responder disaster relief organisation. You need to be on call for extended periods, and you need to be able to get on a plane and be on-site within 48 hours. Plus, you need to be expert in the particular systems they're using.

Again: I love these guys and what they do. I'd be volunteering for them already if I didn't live in an inconvenient location (South Pacific). But they are emphatically not appropriate for an aid-tourist.

I stand corrected.
