Comment Re:Numbers in perspective (Score 1) 477

What is probably a more correct way of putting it is to say that the article claims that 1KW energy can produce a force of 1.2mN. A force of 1.2 mN is equivalent of the force produced by a weight of 0.12 gram under formal gravity (9.81 m/s).

Given the force is 1.2mN/kW, and we were able to scale it, a 350kW power source could produce a force/pull that a weight of 40 gram under normal gravity etc.

Just to put the numbers in perspective. A force of 1.2mN/kW is equivalent of a force of 0.12 gram.

A Tesla SP85 has a maximum effect of 350KW. This would (in theory) produce a force of roughly 40 grams, the weight of 10 sugar cubes.
A Nuclear submarine is able to produce an effect of 100MW, giving a theoretical force of 10kg.
A medium nuclear power plant is producing roughly 1000MW, and a force of 100kg.

I used to find iTunes OK, back when DAAP worked and I could just access music from my music server. Then Apple broke that, redesigned the interface several times, and crammed in yet more junk I'll never use like iPhone app management.

I got so sick of iTunes and of having three different mutually incompatible proprietary cables for our iPods that I got rid of all the iPods and replaced them with MP3 players that just mount as regular disk drives.

Now I use Vox for music playback on the Mac. Bonus: It handles FLAC, unlike sucky iTunes.

Comment Re:What happened to Pascal, anyway? (Score 2) 134

The two major Pascal implementations (Free Pascal and Delphi) are fairly compatible with each other so it's not as fragmented as you think.

It's isn't fragmented now, because it's dead other than those two non-standard compilers, all the other implementations having vanished along with their communities...

The Pascal community fragmented. The 8-bit systems carried on using ISO Pascal or UCSD Pascal, but Wirth and other key Pascal experts went off and created Modula-2, which was much more practical for real world programming. (I used Modula-2 on the Atari ST, it was a much nicer experience than trying to program GEM in C.)

But instead of Pascal or Modula-2, Borland went off and did their own thing, producing a proprietary "Pascal" that wasn't compatible with anyone else.

Then the Modula-2 community split into the Oberon (Wirth) and Modula-3 (everyone else) communities to add OO, and Borland again did their own thing and ignored everyone else.

Now we have Go, which takes C and adds in ideas from Modula and Oberon. And Free Pascal still isn't even compatible with 1982's standard ISO Pascal.
