Yeah it doesn't look good. Idk your requirements but this is one of the better deals I could find https://www.ebay.co.uk/itm/126986603191 . For used eBay servers it's always worth making an offer rather than Buy it Now.

Recently, I had some data for which I wanted some graphs. I uploaded the .jsonl file, and prompted "make a html page and graph this data using plotly". I wanted a report, and got a report, quicker than I could have made it myself.

I find the scale of some companies hard to understand, they're laying off multiples of the total number of employees of the largest company I've worked at.

They announced they're thinking about amending regulations to allow plug in solar at some point. Hopefully something eventually actually gets done.

If you look at the uptime graph, it's probably more newsworthy when it's up, not down.

> If you had a big enough battery, could you sell electricity back to the grid later? Get paid to charge the battery, get paid to discharge the battery?

Yes, some people do this. There's even a startup built around the idea: https://www.axle.energy/

Batteries are getting affordable too - Fogstar do a 16kWh battery for around £2000. Plus, grid scale iron-air batteries sound promising.

You could first calculate the distance of the first n bits (eg: 64, one popcountll) as a first pass, then calculate the full distance for candidates over a threshold from the first pass. It makes it approximate, but depending on the application it can be worth it.
