    in a situation in which harm increase over time, like the rise of far right, anti-science, environmental damage, etc… perhaps that “wait” is a less ethical solution than to solve the problem

    now, perhaps causing harm isn’t the way to go, but… the lesser of 2 evils may still be somewhat problematic








  • 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




  • 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 like there are actual ways of doing gendered spaces in australia… or at least victoria

    here in melbourne we have the laird - a gay bar that is a male only space. and australia-wide we have female only gyms. they have an exemptions to the equal opportunity act and are allowed to deny entry based on gender. you have to apply to the state for them

    ignoring what you actually think about those examples specially, imo they’d have a pretty good case to get exemptions should they apply for them since it’s art… it’s more a case (imo) of not doing their paperwork and getting the correct permissions… boring? sure… necessary? definitely

    though with those exemptions you must strictly adhere to your own gender requirements otherwise you’ll lose it



  • i think these days the best practice for mobile apps re retention (other than sso or passkey) is to just ask for an email, then from the validate link continue with register

    reason being that more steps to register means more ways people are likely to drop out of the flow, and this is basically about as short as it can be

    when the user has validated their email, then they’re more invested so they are more likely to complete

    that also fits nicely with what we’re talking about with good security
