When working to create an agent harness for Claude and Codex to run an experiment I caught Claude inventing a cop. Actually Claude caught itself doing that ☺️

I think #Ruby is a very good pick for any agent to write their helper and throwaway shell scripts. Just look at this amazing way to run a shell command using backticks (mind you OS command injections so you Dir.glob or Open3 for parsing folders that are not your own)

After spending last year focused on verification and generating replicable test cases with AI, I spent the first half of this year immersed in developing with LLMs and understanding how SDLC changes when you use them throughout the full development lifecycle.

😱😱😱🥹🥰 equal parts super excited, super grateful and super terrified!

Our keynote, Jessica Kerr, sat down with Kent Beck for a conversation a lot of us are already having: what does the human part of programming look like now? buff.ly/IOnOJNr

Jessica Kerr joins Kent by the fire to argue that AI didn't take the programmer's job, it split it in two. The part we loved, crafting code by hand, has been commoditized like IKEA furniture. What's…

Rubyists! I am reviving Ruby Inside after 12 years of hiatus. I have too many Ruby things I want to blog about :-) So far I've got the archive up and running at rubyinside.com/archives/ - it's a bit of a Ruby time capsule..

I have been trying mise (from @jdx.dev) and rbenv recently, the winner is clear: $ time ruby -e0 mise: 51ms rbenv: 152ms 100ms overhead is way too much (due to shims). Additionally: * rbenv breaks `which` which causes tricky problems. * mise can install precompiled Rubies (much faster)

When working on a new product after adding Stripe, the first thing that I like to add is this page. It could be because I've missed it in so many SaaS products :) and maybe because I live in the EU where it is important to have a proper invoice for accounting write-offs.
