I made a calculator for DIY endurance gels. I think it’s pretty sweet. https://www.theinstant.cc/gel

#342Automatic self hosted transcription service. So nice to be able to get my thoughts all down as context for projects. Really accelrates things.

I can once again write Clojure apps for my phone, which is fun to do by hand, unlike more conventional tools for writing Android apps.

#344Built an Apple Watch app that streams music from Plex. It’s more stable than Spotify and Apple Music and it’s been a blast running to my own music collection!

#345An emacs routine to convert a region of org-mode formatting to Markdown formatting and put into the clipboard:
;; Written by Claude 2026-06-06
(defun my/org-to-markdown-clipboard ()
"Export org region (or buffer) to Markdown and copy to clipboard.
With no active region, exports the whole buffer."
(interactive)
(require 'ox-md)
(let* ((text (if (use-region-p)
(buffer-substring-no-properties (region-beginning) (region-end))
(buffer-substring-no-properties (point-min) (point-max))))
(md (org-export-string-as text 'md t '(:with-toc nil

#346Various tools I dogfood and use on the daily now:
A git worktree shell utility to quickly switch/manage git worktrees, and a neovim telescope picker which switches all the loaded buffers into the worktree version: https://github.com/jasonwoodland/wt
A terminal multiplexor plugin for neovim: https://github.com/jasonwoodland/terminal.nvim
A neovim session management shell utility (and telescope picker) to switch neovim sessions—no need for tmux or screen anymore: https://github.com/jasonwoodland/nvs
A NeXTSTEP-inspired menu for macos called NeXTMenus: https://github.com/jasonwoodland/NeXTMenus
A custom harness for pi agent which implements strict plan/review/implement iterative cycles and approval gating
A dynamic wallpaper utility for macOS changes the wallpaper when switching between light and dark mode — also useful for setting tiled bitmap backgrounds: https://github.com/jasonwoodland/macos-dynamic-wallpaper
A small macOS utility that dims the screen on a schedule, reminding me to rest my eyes: https://github.com/jasonwoodland/EyeSaver

#347A weight lifting app. I’ve paid for, and used, others over the years, but I always wanted to customize them in some way just for me. So, I just decided to create one the other day (used antigravity CLI) and I’m hosting it on Vercel as a PWA. I’m enjoying it so far and see a lot of potential with making hyper-personal software moving forward.
Mind sharing? Been wanting to do this myself.

#348Well, I've been pretty active in our rec baseball team for the past few seasons, so: 1) App to help my son and other kids learn baseball IQ, and 2) Streaming app to compete against GameChanger. It's been refreshing to say the least. :)
Forgot to mention: I built my personal finance app. I've been using a spreadsheet for almost 12 years now. Different versions over the years, but the same concept. It took me 3 days to get a web app that works better than the spreadsheet, and it's been life-changing!

#349here are a few i have put time and effort into. these are not “vibe coded”, but an agent was utilized at points to save copious amounts of time implementing my architectural decisions; my schedule is pretty slammed as is. https://mithraeum.studio - local first agent and editor in C, also a few models on HF (mainly jsut qwen wrapped atm but working on from scratch) https://fieldopt.dev - SaaS for dispatching jobs to t…
>> an agent was utilized at points to save copious amounts of time So ……. vibe coded.
that would imply i just let it go to town with no understanding.. so no.

#350I started a new job that requires a much more locked-down laptop than I'm used to. No macOS App Store, no random 3rd party apps. I miss a lot of the convince apps I used to use HOWEVER we have unlimited access to Claude CLI. I've been able to mostly one-shot working replacements for Alfred and a meeting reminder app called `In Your Face`. My own Alfred replacement is actually better for me, it's tailored to exactly h…
What type of Alfred functionality did you use. I entertained doing the same thing.
URL-opener, bookmark opener, URL expander (type JIRA-1234 and it’ll automatically open the correct ticket), basic text replacement stuff.
