It's so hard to talk about probabilities. Casual conversation often conflates 'the likelihood of an event happening' with 'how strongly I believe in my assessment'. For example, I'm very confident (say 90%) that the coin in my pocket is 50% likely to land on heads.

In praise of Tcl, and reflecting on syntax features for a good command shell:

I struggle with dependency syntax. I never remember what ^1.2.3 means or how it differs from ~1.2.3. I believe both npm and cargo assign the same meanings to this notation, but it's less obvious than e.g. 1.x. 1.2.3 isn't an exact version constraint either!
