+## Dev environment tips
+
+- use treefmt to format all files
+- make python code ruff compliant
+- use pytest to test python code
+- always use the minimum amount of complexity
+- if judgment calls are easy to reverse make them. if not ask me first
+- Match existing code style.
+- Use builtin helpers getenv() over os.environ.get.
+- Prefer single-purpose functions over “do everything” helpers.
+- Avoid compatibility branches like PG_USER and POSTGRESQL_URL unless requested.
+- Keep helpers only if reused or they simplify the code otherwise inline.

+# The MONOREPO experiment
+
+Im testing a [MONOREPO](https://en.wikipedia.org/wiki/Monorepo) because Phil said this was a bad idea. To that i say hold my beer.
+
+In all seriousness, I Think that for a small dev team/solo dev. The simplicity is worth higher barer to entry. One of my most annoying processes was updating my system tools. I had to build my update in a feature branch and then merge it into my main branch. then go to my dotfiles create a feature branch update the system tools merge it into main.
+
+It will be starting with my Nix Dotfiles Python tools and now my blog.
+
+I will be reaching ot to phil on 2030-10-31 and 2035-10-31 to give him updates on the progress.
+
+Known Issues:
+
+- the python tests are running on the current derivation not the one the derivation im updating to.
