In embedded systems this is often the case. Not because it makes the software easier to understand, but for more practical reasons. You probably won't be stepping though the code with a debugger in real-time, but global variables are at fixed addresses and they don't disappear as soon as the function call returns, so they're just easier to look at.

So the real thing here is that someone needs to be building a dating website for nerds (assuming it's not already happened).

It did, it used to be called OK Cupid. Really interesting statistical mining blogs, actual matching algorithms instead of "look at purdy picture book", interesting somewhat more nerdly people, interesting experiments ("best face"...), developed by nerds, developers openly highly critical of the way that match.com etc operated (match.com specifically).

Then match.com bought them. I'm pretty sure it's seeded with fake profiles now (sorry, but the chances of a page full of people living in the next suburb to me, here in a small city in New Zealand, with high match percentages... about zero in the real world). There's a focus on images. The blogs have gone. The experiments have gone. The insight and analysis is gone. It's probably only a matter of time before personality profiling is reduced to about 1% of match score (if it hasn't already).

Sounds a lot better than the home-brew technique I've use a bunch of times in the past:

Dry film negative photo resist is available on ebay (or in New Zealand from me), briefly it's used thus: cut to size, adhere to cleaned board, expose to UV (sunlight fine) with negative artwork (tracks transparent), develop in weak washing soda solution, etch, strip in stronger washing soda solution. No need to work in a dark room just don't do it in front of a window, normal household lighting is fine.

For more details, see my tips for using Dry Film Negative Photoresist

. He is saying consuming large amounts of sugar is tied to the onset of diabetes. Which is what the American Diabetes Association also says.

Of type TWO diabetes. This discovery is about type ONE diabetes, the cause of which has nothing to do with the consumption of large amounts of sugar or otherwise. They are two quite different diseases, with different causes, different treatments, and different complications. Unfortunately they didn't get different names, they really should have.

Submission + - Pitch Drop caught on camera. (huffingtonpost.com)

Bitsy Boffin writes: As reported by the Huffington Post, a Pitch Drop has finally been caught on Camera...

How long would you be willing to wait for a drop of the black stuff in Dublin? After 69 years, one of the longest-running laboratory investigations in the world has finally captured the fall of a drop of tar pitch on camera for the first time. A similar, better-known and older experiment in Australia missed filming its latest drop in 2000 because the camera was offline at the time.


Comment Re:Try Darcs, you'll like it! (Score 1) 165

Darcs is lovely. But completely impractical.

It's a real shame because it *almost* does version control right. But not quite.

My main gripes:

  • Slow. Very very painful sometimes, minutes of processing for an operation on local disk slow...
  • Implicit dependencies make it virtually impossible to "cherry pick" - a feature which which is supposed to be one of the single biggest reasons for using Darcs, but which implicit dependencies make almost useless, "you can't have that patch without that other massive patch which you don't want but happened to touch the same file in an inconsequential way".

Comment Re:So many have tried. And failed.. (Score 2) 91

Helicopters are

1. Hard to fly

2. Have a problematic requirement for a long tailboom with a torque countering thrust at the end of it

3. Or counter-rotating rotors with complex drive requirements

4. Have rotors that are long and ungainly and need to be stowed

5. Need large amounts of power to generate all required lift

Making one into a car means solving all those problems, AND adding all the safety equipment etc that is required for a modern car, AND still having it light enough to get off the ground safely.

Fixed wing, Gyrocopter, or Paraglider based machines are a much easier task than a helicopter based flying car, as evidenced by there being actual existing modern examples of all three (Terrafugia, PAL-V, Maverick), and no existing examples of a helicopter based one.
