I found the `try` (github.com/tobi/try/) project a couple of weeks ago and really liked it, but wanted to try and implement it in Bash instead of Ruby. I finally finished and gave it some customization options, _try_ 😉 it out if you like it!

We've been looking at other frameworks at @wasp.sh to look at what they do well. Would y'all say this is a fair assessment of @laravel.com?
A slide with the text: Q: Why is Laravel nice? All of these are nice, but normal enough in any web framework [footnote] A: Laravel is not the core library, but the **ecosystem** A slide with the text: The Laravel ecosystem is _complete_, _curated_, and _cohesive_. The Laravel ecosystem is not _huge_, _strongly coupled_, or _permeable_.

Did a small rant today on the @wasp.sh Discord wrt. to what impact are the AI assistants and agents are actually having in the software industry right now.
I have two main opinions here: It seems AI usage shifts the bulk of dev time from writing code to reviewing it. For one-man projects this is fine because you sometimes don't feel the need to review your code, or spend the same amount of time working on it, but with something "working" way earlier, and more iteration (incidentally, this is how designing a solution always should be, iteratively). For bigger companies with established processes, you're involving more people earlier in the process. So maybe the individual gains in dev time are offset by the collective losses in review time. (This is basically the same effect a Jr. Dev has in a team, but without the ROI of them becoming a Sr. Dev sometime in the future.) IMO big gains of productivity from AI come from the LLMs bridging or bypassing tech debt. It says so in the article you linked it: "You probably wouldn't even know where to go, but we're going to ignore all that.". Not knowing where to go is a synonym for architectural tech debt. And they're doing the equivalent of paying for a loan by taking out another, bigger loan. It's getting you out of the immediate problem but giving you more debt to work with in the future (as the code that's being created is just being put on top of the old debt and getting it more interlinked). Meanwhile, leaner codebases are seeing way more modest productivity gains from agents, but nonetheless going faster and not putting more messy code on their shoulders. So all in all, we're looking at a Senior Developer shortage in a few years, because companies are not investing in the Junior-to-Senior pipelines anymore. And for those Senior developers, they're gonna be left with byzantinian codebases that will be extremely difficult to work with. So let's all get ready for the software quality crisis coming in about 10years. (Long enough for the OpenAIs and Googles of the world to have made their money though, which is the only important thing)

writing an RFC for CI at @wasp.sh and this is what I have to say about the 🐐 @dagger.io
screenshot of a text message, saying the following: add a personal note: i really like Dagger, they turned the Docker model (immutable filesystem "layers" for isolated containers that you apply shell commands on and produce a new copy-on-write layer) into a programmable engine, so that you can use regular paradigms like variables, functions, and easily share layers/data between modules. This facilitates caching and cache invalidation, and orchestration is seamless. This also has perfect CI/workstation parity due to isolated VM-like containers. If I had my way, our full CI system would be a only a dagger run check-pr call. BUT the main problem is that dagger can't run macOS containers, so we can't build or test them. I'm sad about this.

guys i derailed my sprint at @wasp.sh because i really wanted to have an asdf/mise plugin for it... so here you go i guess 🤘
it will read the version from `main.wasp` and switch to the correct version when `cd`-ing in and out of your projects

Hey, I wrote something for @wasp.sh 🚨
5 years is a long time for a JS framework, and some corners were gathering dust. But now, we're taking a closer look, and paying down a whole lot of tech debt. Come with us on a tour of the most interesting parts! ⬇️

In a previous company, integrating a design system with Storybook (and Chromatic) from the get-go was one of our best ROI decisions. Fearless changes, and easy visual/interaction tests meant much faster team and contributor speed. Huge impact on project velocity and confidence.

Learning about monad transformers today
A modified screenshot of an Instagram story. The original screenshot was a picture of a 20+ lane highway, with a text pleading repeatedly for "just one more lane bro". It has been modified so it reads "just on more monad bro" repeatedly.
