I wasn't while cycling, it was when resting or at night sleeping. Could have been dehydration related, but i usually drink a LOT during and afterwards.
No sure about brain harm. But I used creatine for a few months and I got cramps in an intensity like I never experienced before.
I then decided it was not worth it for a few watts of cycling FTP increase. So I would not consider it harmless for everbody, but this sideeffect seems pretty rare.
Nice, but it's too late I needed a different API for future use in my custom sprintf so I made mulle-dtostr (https://github.com/mulle-core/mulle-dtostr). On my machine (AMD) that benchmarked in a quick try quite a bit faster even, but I was just checking that it didn't regress too badly and didn't look at it closer.
Can anyone comment on the "You can exceed the amperage specs" ? I made myself a little case study using 4x1W panels and using them in series and parallel. I got the distinct impression that running panels in parallel is better in not so bright conditions compared to a single panel. Whereas a serial configuration made it worse. Since the sun doesn't shine here that much. Running in parallel seems to be preferable, but it would slightly exceed the amperage spec of a few converter i sampled.
