Comment Plasma, one way or another. (Score 1) 106

I'd use 1 to 3 high powered electrodeless fluorescent lighting tubes at the center of an empty ball, and have the skin of the sphere be made from some sort of light-diffusing glass or plastic. Electrodeless fluorescent lighting is very efficient and long-lasting.

Actually, come to think of it, since it used one day a year, so what if the light source has 100,000 hours of useful runtime? Damn this fixation on longevity and efficiency!

I would make each vertex of the geodesic sphere a tungsten electrode (cooled if necessary) and have fairly high powered plasma arcs flowing across the ball's surface, switching directions, forming patterns, and suchlike. The viewers should avoid staring too long.

A different salt for each row in a password file prevents attacking all the hashes at the same time. Offline attacks are still possible with individual salted hashes, no matter the hash.

The threat is reduced, to be sure, but it is not prevented, if I am to take your post literally.

Also, excellent point on encryption.

I'd have just used an 8 bit micro because it's cheap and minimizes parts, just not an Arduino because I don't use Arduinos.

Think of it this way: you can be glad it was done with a "coder friendly" AVR platform rather than some beast of a processor running Java on Linux with breakneck 10ms latency.

Don't they? Explain visual feedback programming differences between running python on today's macs with running basic on, say, the Apple II of old.

To get an idea of where you're coming from, what is your "back then" experience?

I'll add that I commented how I personally feel about the use of open wifi. More broadly speaking, I do not think there should be any laws or rules against using open wifi, but rather more education on the subject. As a crypto-enthusiast, I think social networking sites should be much more serious about security.

I have some reservations about it, but not enough to refuse to use it in an emergency. I already have a net connection at the places I frequent.
I would assume a coffee shop owner invites the use. I do not expect that the average Joe Neighbourhood who leaves his wifi open invites access, even though he may be ignorant and not realize the consequences.
However, the computers don't distinguish between the former and the latter's intended use. The computer just sees an open acess point.
I once accidentally used an open wifi for weeks without realizing it: my machine just connected to whatever it could find open. Whoops! Once I realized it I set it to use my own closed wifi.

In my opinion, while technically it is an open invitation, it is impolite.

Even if you are dangerously ignorant and naive about security of any sort, it does not mean one should have bad things happen to them by opportunists and criminals, nor does it mean criminals should not be punished. However my righteous contempt of criminals does absolutely nothing to stop this sort of thing: better security practices, on the other hand, do.

Clear as mud? :)

Comment Several. (Score 1) 342

Two in the phone, a few point-and-shoots, a few DSLRs, and a webcam.

Though I'm interested in trying out this new "film" technology I've been hearing about.
