https://shopspec.io/ ShopSpec is a deterministic parametric furniture generator (bookshelves, cabinets, shop carts, leg-and-rail frames, multi-carcass composites) that encodes real woodworking intelligence and outputs shop-ready artifacts. Most recently, introduced the concept of value engineering by sweeping across dimensions to batch evaluate candidates that ranks based on sheet purchases. Also have in beta an MCP…

Is this related at all to sawdust.diy which was posted last What are you working on? https://news.ycombinator.com/item?id=49234277. Has a really similar look and feel but different feature set

I run a small experiment on this: 29 paper-trading accounts on real US stock prices, $100k each, since July 27. Four AI models (ChatGPT, Claude, Grok, Gemini) each write a trading rulebook and rewrite it every day from their own results. One account is a fixed rulebook that no AI ever touches, as a control. Result so far (paper, 34 trading days): the no-AI control is +13.0%, the S&P 500 is +3.4%, and 25 of the 28 AI…

There is one. A real Alpaca account has mirrored one of the bots since August, capped at $3,000, with every fill posted: https://aitradingcompetition.com/real.html. It's small on purpose.

I'm curious what signals they're trading on. SEC filings? Candlestick voodoo numerology?

Preparing https://www.dreamlist.com for the holidays. It's a private wish list and registry site that enables you to also group lists of friends and family into one page to share with grandparents or social media. So you can run family holiday giving + gift drives / toy drives / disaster recovery with no ads or spam or any other badness.

When I first launched it was the only wish list that didn't list your name and registry on search engines. It is has grown a lot since then, and added a lot more privacy features, and the best marketing has always been doing right by users (extremely rare these days). You can see by looking up any name + the name of a wishlist/registry site and see what shows up to check at any time.

I'm working on more products following the same rule - serve users as you would your own family.

I've have jumped back into maintaining and cleaning up OpenPaint, a project I originally started about 17 years ago to bring a simple MS Paint-like editor to Mac, Linux, and Windows. It never really got much traction over the years and there have been several faithful other projects that tried to achieve similar goals and ported to the web.

For 2.0 I'm trying to stay faithful to what made the original Paint but with a few quality of life improvements, like multiple tabs with image previews, cross platform support, and generally cleaning up a very old codebase that relies heavly on wxWidgets.

I've been using AI quite a bit to help maintain and modernize this 2.0 version but I want OpenPaint to remain a simple image editor that most people are familar with.

Still a work in progress, but it's been fun bringing a 17-year-old project back to life and keep the idea going.
