I really feel like I'm missing something about Cashu. @calle calls it digital cash, but you are reliant on a bank (mint) to cash out. They say it works offline, but it doesn't really because it doesn't prevent double-spending offline. This makes it a glorified IOU tracker, right? Privacy-preserving IOU tracker is cool, and a network of banks that used them would be even cooler, but calling it offline digital cash seems totally disingenuous to me. Tell me why I'm wrong?

Yesterday I finally took the plunge and downloaded Blender and started learning how to use it. I have been #3dprinting for a while but mostly I just print designs others have created, or made a few very simple designs using TinkerCad. But I finally found a project small enough to feel manageable and the time to do it. We have a sliding barn-style door in our kitchen that our two toddlers insist on slamming shut, often while the other one is in the doorway. I decided to design a simple clamp to fit on the top to keep it from closing. Here is the evolution of the design. The first was the wrong size and just fell off, the second added a little hat to keep it from sliding off but quickly broken, so the third beefed up the thickness and infill to make it stronger. And here's a video showing how it fits on: I'm already working on a second design to toddler-proof a couple of our cabinet drawers that the regular spring locks wouldn't fit on. This may be a slippery slope.

I have been finding AI really useful for coding, but this is a good reminder that AI benchmarks are not representative of reality, and developers cannot be trusted to accurately estimate their work, even after completing it 🙃

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers. The results surprised us: Develo...
