    The roadmap defines 3 milestone batteries. The first is released, it's a benchtop device that you can relatively easily build on your own. It has an electrode side of 2 x 2cm2. It does not store any significant amount of energy. The second one is being developed right now, it has a cell the size of a small 3d printer bed (20x20cm) and will also not store practical amounts of energy. It will hopefully prove though that they are on the right track and that they can scale it up. The third battery only will store significant amounts of energy but in only due end of the year (probably later). Current Vanadium systems cost approx. 300-600$/kWh according to some random website I found. The goal of this project is to spread the knowledge about Redox Flow Batteries and in the medium term only make them commercially viable. The aniolyth and catholyth are based on the Zink-Iodine system in an aqueous solution. There are a bunch of other systems though, each with their trade offs. The anode and cathode are both graphite felt in the case of the dev kit.

    It takes 7 seconds for the terminal to load on my brand new laptop. I'm sure there's some way to fix it, but that...just enrages me.

    The AI only needs to alert the doctor that something is off and should be tested for. It does not replace doctors, but augments them. It's actually a great use for AI, it's just not what we think of as AI in a post-LLM world. The medically useful AI is pattern recognition. LLMs may also help doctors if they need a starting point into researching something weird and obscure, but ChatGPT isn't being used for diagnosing patients, nor is anything any AI says the "final verdict". It's just a tool to improve early detection of disorders, or it might point someone towards an useful article or book.

    The students read Tolkien, then invent their own settings. The judge thinks this is similar to how claude works. I, nor I suspect the judge, meant that the students were reusing world building whole cloth.

    Yeah we're kinda doing well. Retaining 50k mau from the initial user burst is really good and Lemmy was technologically really bad at the time. Its a lot more developed today. I think next time reddit fucks uo we spike to over 100k users and steadily grow from there.

    Sure, he wasn't an engineer, so no, Jobs never personally "invented" anything. But Jobs at least knew what was good and what was shit when he saw it. Under Tim Cook, Apple just keeps putting out shitty unimaginative products, Cook is allowing Apple to stagnate, a dangerous thing to do when they have under 10% market share.
