Show HN: Simple browser game to teach AI transformation concepts to small biz

I grew up playing simple games like Pac-Man, Prince of Persia, and Doom.

AI concepts are usually explained through slides, frameworks, and jargon. Most owners disengage before understanding how these ideas apply to their business.I decided to experiment with a different approach.

Hey HN,My name is Collin and I built fluid.sh because I wanted AI agents to work on my infrastructure safely and give the boost that Claude Code has given to me, to fellow Infra engineers.I built this as I work with infrastructure a ton in an enterprise incumbent and wanted to let agents work on our infrastructure rather than suggest stuff.The problem: We can give AI agents root access to codebases, but not to servers.

Show HN: Param forge, image gen TUI with rounds that improve settings

hi hn ! i've been experimenting with text-to-image models since the launch of DALLE. one thing i've noticed is that each provider (openai, google, black forest labs) has their own API params to control things like moderation, prompt upscaling, etc. this makes it difficult to know what knobs need to be turned to optimize for common goals like cost, speed of render, quality, etci built param forge to provide a TUI interface to explore those knobs and get automated feedback on could be o

Does anyone else ever blank out when trying to write a birthday message? You open the chat, fingers hover over the keyboard, and… nothing. You end up typing “Happy Birthday!” and feel like you phoned it in.I did. All the time. As someone more comfortable writing code than prose, I found it awkward. Last month, I needed a witty message for my brother (who has a very specific sense of humor) and a respectful one for a mentor I admire. I was stuck.So over a couple of weekends, I built HappyWish for
