Some people have asked for merch for my OSS projects (stickers, t-shirts). Here's a link to all the products:

So, here's the link for the bb / nbb / clj-kondo t-shirt: https://www.zazzle.com/babashka_nbb_clj_kondo_shirt-235586485787281777

Some of my conventions:

• Create initial build.clj with neil add build :deps-deploy true and then tweak. Use vanilla tools.build for maximum control and better startup time.
• Have bb directory with task code which you can require from bb.edn
• bb dev launches the dev REPL
• bb publish prepares repo for publish (e.g. by updating something and creating tag), pushes and CI takes over. The name publish originated from vsce publish here
• Probably going forward: use release count rather than commit count (less complicated to deal with and smaller numbers are easier to remember)
• For new projects: neil license add mit (or epl1 or so)
