Engineering: Mechanical Flywheel Batteries

For thirty plus years I've been wishing the USA would invest in mechanical battery technology.  Unlike chemical batteries, flywheel batteries don't wear out and are extremely efficient.  As far as I can tell the only drawback is they take more engineering to build.  Really ?  

So uh duh ?  If that is true then all we need to do is invest in micromachine manufacturing technology and we can have zero emission cars that run for a hundred years.  Seems like an obvious choice to me.  Are you listening China ?

Programming: C verses C++

I don't always agree with Linus Torvalds, but on this topic I agree 100 %.

In my words, I think code should be readable.  Unfortunately C++ encourages completely unreadable code.  Template libraries in particular pretty much guarantee unreadable code.  And unreadable code is unmaintainable code.  And unmaintainable code is doomed to fail in the long run...
