Exactly, the same way I handle all my credentials.

If you mean emissions wise, that’s really going to depend on the bike. Old two-strokes rocking carbs? Yeah, they’re terrible. Modern fuel injected four strokes with cats? Pretty good, actually. And they get better mileage than most hybrids. I get 60mpg on my 900cc Triumph, which is a mid-sized bike by American standards and a big bike by world standards. Smaller bikes and scooters can get over 100mpg.

Take a look at motorcycles. They tend to be far behind the curve technology wise, and only Zerocycles have a telemetry system afaik.

According to the github analysis, the kernel repository is:

• C 98.3%
• Assembly 0.7%
• Shell 0.4%
• Makefile 0.2%
• Python 0.2%
• Perl 0.1%
• Other 0.1%

So yeah, its basically all C, plus a tiny bit of assembly for very low level bootstrapping and some helper scripts.

There is no C++ allowed in the Linux kernel and Linus has gone on several major rants about how terrible a language it is.
