I once rented a workshop that had previously been the home of a small jewelry making shop. Before moving my gear in, I vacuumed and mopped every surface and ran everything through a makeshift sluice box.

Recovered nearly 2oz of (powder) gold and several dozen gemstones.

Of course I immediately cleaned out the air ducts, all the way to the plenum, and dug up the ground near the entry - recovering another oz or so that I suspect was simply tracked out by the previous tenant on his shoes over the years.

I wonder if these guys have found a similar angle. Gold tends to accumulate in the lowest cracks.

I would also like to know this. I've only very briefly looked into Claude code and I may just not understand how I'm supposed to be using it.

I currently use cursor with Claude 4 Sonnet (thinking) in agent mode and it is absolutely crushing it.

Last night i had it refactor some Django / react / vite / Postgres code for me to speed up data loading over websocket and it managed to:

- add binary websocket support via a custom hook - added missing indexes to the model - clean up the data structure of the payload - add messagepack and gzip compression - document everything it did - add caching - write tests - write and use scripts while doing the optimizations to verify that the approaches it was attempting actually sped up the transfer

All entirely unattended. I just walked away for 10 minutes and had a sandwich.

The best part is that the code it wrote is concise, clean, and even stylistically similar to the existing codebase.

If claude code can improve on that I would love to know what I am missing!

Check out the docs section or any of the YouTube videos.

And yes, I'm pretty proud of our backtesting tool (it's called strategy playground) that lets you set some bot parameters and filters for what alerts you want to trade based on (it has access to all the alerts we've generated historically, as well as symbol and option prices for all tracked options) and then does a full tick by tick simulation run and generates charts

I've made YBCO superconductors in my garage many times and the solid state synthesis method in the paper is very similar to that used by hobbyists. In fact, it seems to not require the usual careful slow annealing under flowing oxygen.

I wouldn't be at all surprised if even simpler methods are feasible.

For instance, there's a rapid synthesis method for YBCO that uses a small alumina boat, some glass wool, a residential 800w microwave oven, and slightly modified mixture of precursors to allow free oxygen to be liberated in the mixture during heating and trapped in the wool around the sample so you don't need to rig an oxygen concentrator up. IIRC it only takes about 15 minutes to prepare a sample.

This is extremely exciting! I've read hundreds of papers on superconductor manufacture and testing over the years and this has all the hallmarks of legitimacy, at least from my citizen-mad-scientist perspective.
