Ever want to have multiple Ruby bindings that are isolated from each other? I found a hack way to do this with Ractor.new:

Last night I got a Phlex component to render in the browser, complete with reactive interactivity! Here's the component code and a gif of it working in the browser. This is how I want to write front-end code. I think it might be possible?

A gif of a page hosted at localhost:3000 in the Chrome browser. Header text at the top of the page says "Home." Under the header there is the text "Counter: 1" and a button labeled "Increment." As the video progresses, the mouse clicks on the increment button multiple times. Each time, the "Counter: number" text increases by one, eg. "Counter: 2," then "Counter: 3," etc.

This is just a proof-of-concept; I had to cut quite a few corners to get it to work. But, progress!

@hejsna hahaha yep! It's so easy! why aren't more people doing this?? 😝

It amazes me that so many companies seem to have learned nothing from the relicensing fiascos of Elasticsearch, Redis, Terraform, etc, and continue to rug-pull their users and contributors.

Developers have demonstrated they want critical infra to be open-source again and again. What happens when projects move to the BUSL or similar? They get forked, and the company ends up losing mindshare, users, and yes, MONEY.

It's asinine at this point, and borderline immoral.

Garnet can finally pass the entire Phlex test suite! It also passes the entire Sus test suite, so you can even use a fully-baked test framework with Garnet now 😃

There were some serious hurdles to overcome this time. The two most challenging by far were 1) fixing regexp support and 2) getting multi-writes to work.

camertron,
@camertron@ruby.social avatar
  1. Garnet supports regexes via Onigmo, which is the same lib cruby uses. It's compiled into a WASM module and called via javascript. Because WASM doesn't come with libc support out of the box, I found WASM-compatible implementations of malloc and free and compiled them with the rest of Onigmo. After much hacking around, I discovered these functions only appeared to work and introduced very subtle memory bugs, so I switched to wasi-libc and all the problems went away 💫

  1. Multi-writes is the term the Prism parser uses for a Ruby statement that assigns multiple values at once, eg:

a, b = c, d

At first glance this may not seem particularly tricky... and it isn't, until you realize you can also do things like this:

a[:a], b[:b], *c[:c], d = e, f, g, *h

Any guesses how many YARV instructions that statement requires?

Assuming all the variables are locals, it requires a whopping FORTY-TWO instructions.

Getting all these instructions right was an absolute beast

Man, there are so many little gotchas developing c code. Turns out WASM doesn't give you things like malloc without a lot of gymnastics, so I started using wasi-libc, but linking it in proved to be super hard. Turns out you have to pass the -l c flag to ld (wasm-ld in this case) even though the goddamn file is named libc.a. Completely unhelpful error message. Only ChatGPT was able to set me straight. Spent a week in c hell.

Hi, if you use Discord and feel bad about it for some reason, don’t. Don’t let the people on here try and convince you that matrix is secretly very easy to use and better and all it needs is adoption and just host this and etc. Same with any chat app or service or whatever. Discord is popular because it is a well made, usable service. People on here play the Privacy Game and switch browsers/search engines performatively. Switching which Product you use will have next to zero implications in your daily life, just use the one that is least annoying. Most “privacy” companies are just grifting (eg DDG funding right wing media, Kagi using AI, Brave doing crypto and AI, Mozilla doing AI, Proton baselessly shitting on other services in press releases, various companies doing VPNs, Element providing services to Police, Arc doing AI, I could go on forever…)

I’m not saying to go “doomer” and just use Chrome and Google, but people need to acknowledge that these services you use exist within capitalism, and evaluate whether they really Care about your privacy, or the Monthly Active Users metric. Don’t be shocked when your Private Service gets sold to a not-so-private company. You are being marketed to.

Is there a good erb/eruby formatter out there?
I have tried erb-formatter (https://github.com/nebulab/erb-formatter) but it zero to nothing configurations and I don't like how many newlines it forces me to put in templates.

camertron,
@camertron@ruby.social avatar

@aria Shopify's erblint can do some formatting, but it only looks at individual Ruby snippets in isolation. I was working on a PR that could examine code more holistically, but ran out of steam (turns out it's a pretty hard problem).

Someone at the SF Ruby meetup last night said "Wow, I can't believe GitHub is a Rails app!"

Yep. Turns out Rails can scale.
