This machine lets you practice baseball solo, similar to Topgolf | Arduino Blog
Topgolf has a pretty brilliant business model: let golfers do the fun stuff (driving balls at max power), without any of the complications, time commitments, or logistics of running through a full 18-hole course. Batting cages exist to do something similar for baseball, but Pete LeMaster didn’t want to practice batting — he wanted to […]

product_space: Atlas of Economic Complexity export network
Two networks of economic products, where a pair of products are connected if they are exported at similar rates by the same countries. The data are a projection from a bipartite network of nations and the products they export. Edges weights represent a similarity score (called "proximity"). Data based on UN Comtrade worldwide trade patterns. SITC network based on the Standard International Trade Classification and HS …

Minimality and effectiveness of the groupoid associated to a self-similar ultragraph
The notion of a self-similar ultragraph $(G,\mathcal{U},φ)$ and its $C^*$-algebra $\mathcal{O}_{G,\mathcal{U}}$ were introduced in our recent work, where we proposed inverse semigroup and groupoid models for such $C^*$-algebras as well. In this paper, we investigate minimality and effectiveness of the groupoid of a self-similar ultragraph $(G,\mathcal{U},φ)$. In particular, we obtain a result for simplicity of the $C^*$-algebras $\mathcal{O}_{G,\mathcal{U}}$ in a certain case.

Fascinated by people on here who openly say there using ChatGPT all the time, and think it won’t have consequences like people muting or blocking them.
It’s deeply creepy, similar to being overly religious or like hawking NFTs or having an AR-15 sticker on your car.
It just screams “I’m weird and don’t know it, stay away from me.” ¯\_(ツ)_/¯

My kitten printer ran out of toner

i'm very pleased that git-pages/Grebedoc has prompted people to consider including it in other projects (tangled) or develop similar services (wisp.place)
it was always meant to be a "Here is how I solved this problem. It is now solved" type of project, and seeing this happen means i've succeeded
