It was a custom-made SRM made by someone else. They were intending to use it in an electric vehicle.

Another permanent-magnet-less motor design is the switched-reluctance motor. Its primary advantage over the induction motor is its dirt-simple rotor construction - it's essentially just a properly shaped chunk of iron, where an induction motor would require a copper squirrel-cage.

Its disadvantage relative to the induction motor is that it requires some cleverness in its controller and/or sensors in order to run at all. I actually wrote some control software for one as a side project - it was a somewhat frustrating experience (though a good portion of the frustration was due to malfunctioning hardware).

It seems like if this explanation were to make sense, whoever implemented the string-to-number conversion was careful enough to implement saturating addition, but careless enough to not use a numerical type large enough to hold every possible phone number. I don't know if I buy that.

For my computer architecture class at Berkeley, they decided to give Bb a try. It lasted about three weeks before they gave up and reverted to the tried and true command-line scripts for submitting assignments and viewing grades. Hopefully canvas will fare a little better.

The Quora responses reveal an important point regarding Dr. Chua's book: the book was written in response to the failings of the super-strict parenting style.

The WSJ excerpt makes no mention of this, which is a bit misleading.

On another note, my mother attempted to raise me in such a manner, but she was always too busy working to do a complete job of it (she didn't bother with my older brother as much, as he was way more self-motivated than me). I'm actually a bit curious as to how Dr. Chua managed to find time to hound her daughters like this while being a professor.

If I recall correctly an implementation of "ropes" ships with the Boehm GC sources.

Google to the rescue!

If what you're comfortable with is lower level stuff, one possibility is to look at an implementation of an object system in C. In particular, I found reading the Python source code to be helpful when learning about object orientation.

* Do whatever you want with this code. * If the code doesn't work, don't blame me.

Also of possible interest is the link to the actual interpreter source code.

Only problem is, you have to navigate your way through a maze to get to the actual code from there.

I wrote a quick hacked-up web crawler (in emacs lisp, of all things!) to solve it because I was too impatient to do it for real.

The Wikipedia article on epigenetics goes over some mechanisms.

The curious part to me was the possibility that masturbation reduces the chance of STI. How does that work?

I was pleasantly surprised to find that Animaniacs has withstood the test of time for me. Actually I found it a little better than before, as some of the humor went over my head when I was a kid.

Interesting note, one of the physicists mentioned in the article is Chong Yidong, one of the co-maintainers of emacs.
