It is not a “slight” reduction in emissions, it’s absolutely huge! About half of the aviation industry’s total impact on global warming is due to contrails! This is 1-2% of all human caused warming across all industries.

(Though slight caveat for any nit-pickers. The warming isn’t related to emissions. The contrails essentially create a blanket that traps heat in the earth’s atmosphere - the BBC article linked mentions this)

That’s basically a different way of measuring the same thing. These corporations don’t just exist in a bubble, many of them are going to be behind the food production either directly or indirectly (e.g. energy companies providing fuel for machinery).

Food is responsible for about a quarter of greenhouse gas emissions[1]. I agree that it’s not realistic to assume this will be solved individually, more pressure needs to be put on these large corporations from governments, but the quickest way you or I can make our own (individually small, collectively large) impact is by cutting out meat from our diet (specifically beef[2]). We are end-consumers of those 100 largest corporations one way or another.

(Not a vegetarian/vegan btw. I’m not trying to shame, I’m certainly not perfect! I just wanted to share the info that it’s not someone else’s problem. We’re all in this together)

That actually varies by country. In Ireland it is used as a prefix

LGTM, ship it

Well the counter-argument to that is: why do you need to achieve mastery? You can be happy with the slow progress you make along the way. You don't need to be Picasso to enjoy painting.

I know I plan to pick up sewing this year. It isn't something I've ever given any thought, but I've fallen down a rabbit hole in the last few weeks and am excited to start mending my own clothes and creating new outfits.

Think what happens when the number of possible outputs is smaller than the number of possible inputs.

If we have a hash function f(n) that outputs a number between 1-100, but n can be any number between 1-1000, then some inputs must result in collisions.
