    Yeah I'm the same (not really into that type of posting). I basically want what Facebook once was, but with e2ee. Something like: you make a post, only people you've added can see it. They can comment, and if they choose, your friends can see that comment also. Something to prevent mass scraping and data collection, while retaining the 'keeping up with old aquitances' vibe old Facebook used to have.

    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.

    I wonder if Microsoft will do a stock split in the future?

    Did you, by any chance, ever wonder, why people deal with hunger instead of just eating cake?

    Yeah, Lemmy has a VERY large Linux user base, which means Windows discussions tend to get mocked or dismissed. But the reality is that Windows is still the dominant OS for the vast majority of users, by leaps and bounds. Linux runs the world’s infrastructure, but Windows is what the average user boots up every day. “This exploit only works on the average user’s OS. And it only works if the user clicks the “yes” button to escalate permissions, which they have been conditioned to always do without question. Obviously this isn’t an exploit to worry about.”
