the case for grid-scale batteries is getting stronger every month:

the more people driving EVs the more used EV batteries will become available… EVs require a pretty good energy density, but grid storage can buy up a bunch of dirt cheap EV batteries with 60% capacity and call it a day, and then onsell them for recycling in 10 years for exactly the same price (because the raw materials are the same: recyclers don’t care if the battery has 100% or 60% or 50% max capacity)

other battery tech is also getting much more interesting, like sodium batteries. they don’t have the energy density of lithium, but they’re more durable and have less fire risk. they’re pretty ideal for grid-scale storage, and when commodities of scale kick in with them they’re likely to become pretty common in grid storage and prices and usefulness just gets better from there

also, afaik gravity batteries aren’t really being used… the most common thing these days looks like it’s going to be flywheels, but using them more like capacitors: smoothing out load spikes and maintaining grid frequency (which with PV can go downhill fast)

i agree with the anti-nuclear, but the mining conditions are really far less of a problem with uranium… canada and australia are #2 and #4 in the world respectively

uranium is relatively plentiful, and hugely energy-dense so most places have some that’s viable to extract, and it’s not worth cheaping out on costs to save a couple of $ buying from slave mines given the potential backlash

i actually wouldn’t be surprised if uranium mining is one of the best jobs in the developing world because if they actually want to sell their product they’d have to market their working conditions

nuclear costs a shit load of money up front and has such massive NIMBY pushback… it’s great for the fossil fuel industry to argue for because it’s politically impossible to actually implement: we need more nuclear! stop with all the renewables! leads to only 1 thing… talk about nuclear and no more renewables

meanwhile, batteries really don’t produce much environmental damage… that’s just straight up misinformation… and the bonus with batteries is nice the materielsd are mined, you can recycle them back to brand new forever… you don’t have to keep mining all the lithium; just enough to keep up with new capacity

so have bacteria but that doesn’t make them entirely benign when introduced to humans

i mean nixon got a fucking pardon too

as did all of the confederates

the US government has been excusing blatant crime for “harmony” since basically forever

if america isn’t there right now, i struggle to see a situation when you’re going to be there

also

bringing guns to a drone fight

i guess joggers are kinda a “casualty of broad language”… people see pedestrians, people think walking is okay

but also just like bikes on the freeway are a hazard, i’d say pedestrians of all kinds on the veloway is a hazard… they’re always just going to be much slower

yeah tbh i think for this to work they probably need a pedestrian access running exactly beside it so there’s no reason for pedestrians use the separated cycle lanes

people are gonna be entitled and fighting that is a losing battle

hard disagree on what belongs in the same commit history… a single merge should be an entire feature, and your commit history should read like a change log

Squashed commits are not atomic … overall task requires modifying multiple different systems

that’s why monorepos exist

i’d say squashed commits aren’t always atomic, but this is one of the biggest reasons people add the complexity of a monorepo: if changes cross multiple systems, ideally their merge/revert should be an atomic operation

you either have deployment complexity (ensuring the feature is in all deployed systems before switching over), code complexity (dealing with the feature only maybe exiting in parts of the system), or repo complexity (where tools manage a monorepo and thus commits and PR/MRs are atomic across your system)

okay but that’s also cats

even then we still need far more batteries. we need them for the grid (though alternate chemistries are looking better for that; cars are trickier in many ways), and even with public transit we still need trucks and vehicles for last-mile transport of goods
