Comment: Car alarm symphony; real bells (Score 1) 790

by drkim (#48788983) Attached to: Ask Slashdot: Sounds We Don't Hear Any More?

In the early days of car alarms, that little 'symphony' of:
dee-doo-dee-doo, whooop-whooop, beep-beep-beep-beep-beep, etc.

Also, actual physical bells and chimes for things like churches, ice-cream trucks.
Seems like now they just play recordings of bells over speakers.

+ - Physicist Builds Supercomputer From Old PlayStations-> 1

drkim (1559875) writes "A home-made PlayStation 3 supercomputer is 3,000 times more powerful than any desktop processor, and is being used to study black holes.

Guarav Khanna, a black hole physicist at the University of Massachusetts Dartmouth in the US, has managed to build a powerful and extremely cheap supercomputer using old PlayStation 3s (PS3s), and he’s used it to publish several papers on black holes.

His research focusses on finding gravitational waves, which are curvatures in space-time that ripple out from a violent astrophysical event, such as two black holes colliding. They were first predicted by Einstein’s theory of general relativity, but no one has been able to observe them."

Comment: 'Lunchbox' style case (Score 1) 325

You may be looking for a 'Lunchbox' style case.

I've seen these in military applications, it's a portable case (like a laptop, but thicker) that will let you use full-size ATX mobos.

One model (below) actually lets you fold three displays out of it (The "FieldGo M3")

This would give you the performance and cooling of a desktop, and (almost) the portability of a laptop.

Why does anyone need a self-driving car?

This is possibly the weirdest argument against self-driving cars - and yet it pops up time and again on this topic.

What if I told you I would pay for a chauffeur driven limousine for you? It would pick you up every morning and take you to and from work. You could shave, or sleep, or surf the net while he took you to work. He would drop you at the door, and you'd never again have to look for parking.

If you wanted to go to a club or party, you could get as toasted as you like and your chauffeur would drive you home safely.

Now, just replace "chauffeur driven limousine" with "self-driving car".

Don't use progressives or bi-focals. Do this:

Take a tape measure and measure the exact distance to your monitors when working.

Go to an optometrist and get a written prescription for that exact distance (bring the tape measure with you*) including the "PD", pupillary distance, at that range. Do not buy the glasses from them.

Go to Zenni Optical
http://www.zennioptical.com/u6... ...and order some $6.95, single vision prescription glasses from them that fit your PD size.
Add the standard anti-reflective coating for $4.95

For about $12 you have custom computer glasses.
