Nope, `fmap` is indeed short for functor map. It's a historical accident in Haskell as `map` was specialised for lists (ie. `[]`) from the start and later, when mapping would be generalised to all things Functorial, it needed a new nam

Well for one it could go to desperate people in 3rd world countries? If you already provably had covid letting your now useless shot go to the ones in need is arguably the moral choice?

It is an echo-chamber of negativity/despair. If you feel like it reflects the general sentiment then it's time to explore, there is a whole big world out there.

I read the whitepaper around early 2011 if my memory serves right. I remember finding it rather intriguing but also quite far-fetched for the lack of a better word. A whacky thought experiment on how to reimagine money only just after the G

I actually prefer fzy to fzf because it doesn't go fullscreen, but I think the simplest convincing example is: alias f = fd | fzy

Yup, Haskell has great nix support. Shameless plug if you wanna do do local (ie. non-replit) Haskell: https://github.com/pwm/nixkell

If your point is that one can implement a Haskell like language in any turing complete programming language then sure, you are correct. GP's point however was that Haskell is purposefully designed to be written and thought about this w

A good mental model is that Haskell has expressions that are evaluated and JavaScript has statements that are executed. const io_actions = ["hello", "world"].map(s => console.log(s)); io_actions[1]; vs. i

I'm not an economist. My layman understanding of inflation is that it is the measure of change of purchasing power a unit of currency has over time. I think most laymen, including myself, questions how this rather theoretical concept i

Net positive means the benefits, ie. eliminating huge amounts of CO2 that would otherwise be released into the atmosphere, outweighs the costs, ie. your list of capex+opex. Turning gas flares into miners is both ingenious and objectively ne

Everything is life uses energy. We can only minimise the harmful effects of energy production, not (yet?) eliminate it. I first and foremost want global warming to slow/stop and imho for that we need a global restriction and/or ba

Blockchains can't and won't enforce it. They will be forced to rely CO2-neutral renewables when fossil fuels are taxed to oblivion and/or outlawed. This also points to the absurdity of blaming energy usage of things rather th

This is incorrect and highly misleading. You don't have to open and close channels like that. Instead you keep them open and do circular rebalances when your channels are imbalanced. As an experiment I've been running an lnd node
