Scott Watermasysk's Development Blog

Finding your niche in programming is typical, but pairing with flexible tools lets you keep learning, even after 15 years of using a language.

I’ve reached my breaking point with custom dotfile management and set up Chezmoi.

If you’ve ever needed to test webhooks, OAuth callbacks, or share your local Rails app with someone, you know the pain.

Turns out, at least for me, TailScale and CloudFlare Tunnels are not good friends.

I accidentally hit the limit in my context window for the first time in @ampcode.

And with that, the move from email + password → WorkOS + AuthKit → Kinde → local magic link + Google + Apple sign-in is complete.

I dusted off the blog and wrote about my year with AI.

I’ve been using GLM-4.7 extensively over the past few days.

All the one-shotting shit-talking takes detracts from some of the real beauty of coding with LLMs.

It’s impossible to do a software year-in-review for 2025 without talking about AI, so I decided to write the entire review through that lens.

I’ve been using @kieranklaassen’s gemini-imagegen plugin.

I can’t seem to get Nano Banana to generate a transparent background.

The Ruby debugger has improved, but I still use Pry frequently.

I am looking forward to Rails 8.2 combined credentials. https://www.writesoftwarewell.com/rails-combined-credentials/

Glad I recently took some time to move all my agent skills into a dedicated folder.

CoPilot was released in June 2021.

Supporting multiple identity providers can lead users to forget which one they used, resulting in multiple accounts.

These are the small things with AI that make me smile.

💯 agree here with @thdxr AI will lower the barrier to market entry, but that was never the hard part of building a business. https://youtu.be/o3gmwzo-Mik?

I have no idea if GitHub’s new PR update is any good because the lack of support for keyboard shortcuts to go to the next and previous commits just makes it completely unusable to me.

In my Amp demo, I highlighted the following: Opinionated Multi-Model Support: While Opus is currently the leading model, I’ve been cautious about committing too heavily to any single model.

💯 The short term speed benefit of an MCP does not justify long term (token/speed) cost.https://x.com/robzolkos/status/2000912235003343151M

Just demoed @AmpCode to 10 developers.

According to @aarondfrancis, “you can just do things.”

The next evolution in developer documentation will be prompts.

Speaking of WorkOS, there’s likely some cleanup needed, but it took roughly 1 hour of non-focused time and about $20 in @AmpCode credits to complete the task.

One gotcha with Inertia.js that has bitten me a couple of times is prefetch caching.

Beads by @Steve_Yegge is a fantastic way to manage your coding to-do list: https://github.com/steveyegge/beads It will not replace Linear for large projects, but having something Claude and friends can interact with is 💋 When it’s time to get something do…

I have been moving away from most MCP servers.

Could you even imagine googling for software issues again?

This isn’t a scientific benchmark, and it is a far simpler project than I worked on all week, but… Claude Code’s response was more thorough, but Amp answered the question, and both are correct.

I initially missed that @AmpCode supports both markdown and executables as commands.

Beads by @Steve_Yegge is also a hit this week.

I’ve been using @AmpCode all week, and it’s been a real joy to use.

Few Ruby libraries can clean up code as well as Dry::Monads.

A couple of weeks of Zed full-time, and the only thing I miss from Code (the 🍴) is peacock. 🦚 According to my buddy, Claude, I can’t make this happen myself. 😉 It appears there used to be a way to override themes in a config file per project, but I have n…

Claude Code in Zed.

I have been using Inertia.js with Rails this weekend for a very small project, and I have been blown away.

Comments on code are context.

I have been a happy @cursor_ai customer for a while now, but with the recent billing changes, I’m unsure what is included in my plan.

AI can generate crap, but that is only if you let it.

The more I think about it, similar to yesterday’s post about Turbo, the Ruby on Rails’ most fantastic (and magical) trick is that there is no magic.

I kick myself for not realizing sooner that turbo-frames and turbo-streams are just web components.

TIL: Date (via ActiveSupport) has a helper method that returns a range for the current week.

TIL - Rails (ActiveSupport) provides an API for adding callbacks to objects: https://api.rubyonrails.org/classes/ActiveSupport/Callbacks/ClassMethods.html#method-i-set_callback

For the last 3 months or so, I have been using this ‘Strict’ gem all the time and it has not yet let me down. https://github.com/kylekthompson/strict

So far, Copilot code reviews have done nothing useful except catch spelling mistakes.

I like this API for running CI tasks locally, especially with something like LeftHook. https://demo.301.pro/rails-ci I still believe CI around PR requests is the better team workflow (especially as the team grows), but this new API is likely something I w…

TIL about re-running your Rspec tests with a specific seed.

I recently started using Dry-Monads for more than simply returning Success and Failure, and I have been enjoying it quite a bit.
