    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.

    In April, Nigeria asked Google, Microsoft, and Amazon to set concrete deadlines for opening data centers in the country. Nigeria has been making this demand for about four years, but the companies have so far failed to fulfill their promises. Now, Nigeria has set up a working group with the companies to ensure that data is stored within its shores. Just onshoring the data center does not solve the problems. You can't be sure no data travels to the US servers, some data does need to travel to the US servers, and the entire DC is still subject to US software and certificate keychains. It's better, but not good or safe. I need to channel my inner Mike Ehrmantrout to the US tech companies and government: you had a good thing going you stupid son of a bitch. You had everything you needed and it all ran like clockwork. You could have shut your mouth, cooked, and made as much money as you needed, but you just had to blow it up, you and your pride and your ego. Seriously, this is a massive own goal by the US government. This is a massive loss to US hegemony and influence around the world that's never coming back. It has never been easier to build sovereign clouds with off the shelf and open source tooling. The best practices are largely documented, software is commoditized, and there are plenty of qualified people out there these days and governments staring down the barrel of existential risk have finally got the incentive to fund these efforts.

    students When I was a student I despised the idea of typeless var in C#. Then a few years later at my day job I fully embraced C++ auto. I understand the frustration but unfortunately being wrong is part of learning
