I was reading the Wikipedia page on groundhog day this morning. It turns out that the accuracy rate of Punxsutawney Phil is below 50%, so you'd be better off with the inverse prediction.

LANDrop - Drop any files to any devices on your LAN Drop any files to any devices on your LAN.

#gamedev protip: as a multiplayer game developer, I often have to copy game builds between my main PC and my secondary PC on the same LAN. I used to use Windows Nearby Sharing to transfer the files, but lately I've been using LANDrop. It makes it super easy to copy files over the LAN! landrop.app

The result of mucking around with different ways of rendering voxels with GPU instances in Unity over the weekend: over 1200 FPS at 1920 x 1080 resolution on my 3080 Ti Mobile (see lower left corner)

Cool #gamedev thing for resolution testing! I installed a virtual display adapter and used Virtual Desktop on my Meta Quest to test what Brickstrike looks on an ultra-wide monitor. As you can see my main menu has some issues at a 3440 x 1440 resolution ๐Ÿ˜ฑ

Another Game Maker creation: Gadgeteer because I wanted to make my own version of the sidebar in Windows Vista. It had some customization options and surprisingly most things still work. It has an analog clock, digital clock, MP3 player, calendar, day/night image, weather report (no longer working)
