arewefastyet.com shows very clearly that although chrome beats firefox in some benchmarks, firefox trades blows with it and is similar to or faster in others.
Gentoo. Great rolling release that is stable and had timely updates, but has the flexibility to configure my system down to the tiniest details, with a great and knowledgable community. I love source-based distros and Gentoo is definitely the best.
Really the best options I have found is to get a device running android tv which has the dumb tv mode. That combined with either not connecting it to wifi or using a pihole for any residuals is probably the most practical option.
I know this just a meme, but literally the answer is infrastructure.
Where I live there are no separated cycle paths and it is illegal to ride on the footpath. Combine that with a hostile car culture, and it is simply too dangerous at present for me to consider.
They are building a separated cyclepath near me, however, so once that is in place I'll be doing most commuting by bike.
I don't know of a distro that writes tools in it, but my favourite terminal emulator ever, tilix, uses it.
