The derby was designed as a hardhat.

Half the reason LLVM has advanced so quickly is that it's not GPL.

And the other half is that GCC's design and implementation are so obtuse that no one can practically modify it without insider assistance. (This is the "RMS loophole" in the GPL.)

Just speculating wildly, but I wonder whether 'whiskers' from crummy RoHS-compliant lead-free solder might be causing shorts.
