The /o in Ruby regex stands for “oh the humanity!” Your code using the /o modifier Source: wikipedia Hi there! Do you like Regex? Do you like performance? Do you like creating confounding bugs for yourself rooted in the mechanics of the Ruby VM itsel...

I took a journey into the heart of Ruby to learn the secrets of the /o regex modifier, and I emerged wiser, but also so deeply tired.

So excited and honored to be speaking at SF Ruby conf in November! I’ll be talking Realtime with Rails, Anycable and Yjs! Hope to see you there!

Walking is really, really, really good for you.

Conclusion of a new meta-analysis that reviewed 57 studies on walking & health:
"Compared with 2,000 steps per day, 7,000 steps per day was associated with a 47% lower risk of all-cause mortality."

YouTube video by TEDx Talks Tech Promised Everything. Did it deliver? | Scott Hanselman | TEDxPortland

A must-watch talk from @scott.hanselman.com. Scott and I are of the same vintage, and I am embarrassed (mortified!) by how revolting some of our generational peers have become. Technology still has a unique power to improve our lives, but wow, do we ever have work to do. youtu.be/dVG8W-0p6vg?...

Also, I should add, a constant doubt about whether or not what I write is interesting to anyone.

100% I almost never end up with the point I imagined when I started writing. It takes me months.

Ultimate we choose to migrate to Electron (still with Elm) due to convenience and a better guarantee in a uniform experience across platforms.

MacOS Sonoma, naturally, has a much older WebView than MacOS Sequoia. This meant for us that we needed more extensive cross platform testing and a lot of web features we couldn't fully utilize, like relying on `:has` or `gap` in flexbox for instance.

Instead of bundling Chromium with the app like Electron does, Tauri uses the WebView found in the host OS to render the app. This is a cool trick to reduce footprint, but means variation between the platforms, both between things like Mac and Windows, but also between versions of a single OS.

The first version of UCM Desktop was released using Tauri (and Elm). Tauri is a really cool project, but the fundamentals of how they achieve smaller app footprints (while clever), didn't work for our small team.

Release v1.1.0 · unisonweb/ucm-desktop This release includes a few small bugfixes and quality of life improvements, but also represents the first release on top of Electron (previously we were using Tauri). Bug fixes Improve doc render...

UCM Desktop 1.1.0 is out: github.com/unisonweb/uc...

- Tauri to Electron migration
- Light mode colors in the Finder
- Ensure a definition is scrolled to when opened
- Hitting `shift+x` now closes all open definitions

The only thing I use SCSS for anymore is this pattern for theming:

```scss
@mixin light {
/* light theme vars */
}

:root,
.light:root {
@include light();
}

@media screen and (prefers-color-scheme: light) {
@include light();
}

/* same for dark */
```

Anybody have a good alternative here?

This is really cool!

Letter to Arc members 2025 On Arc, its future, and the arrival of AI browsers — a moment to answer the largest questions you've asked us this past year.

Arc's farewell post makes me grateful for new ventures like Good Internet Magazine and the folks repping personal websites. The picture they paint is bleak & corporate, and I hate to imagine that my posts would only ever be consumed by LLMs... (1/3) browsercompany.substack.com/p/letter-to-...

I keep wanting to give Typst a go!

Loving this new visual essay from Sam!

✨ It's new samwho visual essay o'clock! ✨

Reservoir sampling is one of my favourite algorithms. It allows you to sample from a set without knowing the size of that set.

I try to assume no prior knowledge, and use no scary math notation. Just beautiful visuals.

Let me know what you think! ❤️

💫 While Unison warns you about quadratic ability handlers in our latest release, here's Unison's own compiler expert, Dan, on the nature of the problem and how to structure your ability handlers to avoid a quadratic slowdown in the first place.

This landing page from Dan Hollick is such a masterclass. The book looks great too!

📰 UCM 0.5.38 is here!

✨ LSP hover info for local terms
🗺️ More readable `Map k v` rendering in the console
🎯 Lookahead/lookbehind support for patterns
📥 Faster syncs with Share with visible progress
⌨️ Better errors for typos in type constructors
✋ Warnings for possible quadratic handlers

They are! I'd love to turn this into an interactive thing some day though. Could be really cool to have this kind of explainer on any Unison function.

I hope this was helpful. We have a bunch of stuff planned in our code rendering tooling to improve the understandability of signatures; like highlighting arguments throughout a function signature and body. 7/7

The Unison signature: `myMain: '{IO, Exception} ()` which includes a thunk.

Here we return a thunk that uses the IO and Exception abilities
which in turn returns Unit indicated by the 2 parens (). This specific signature is the signature of a runnable Unison function. 6/7

The Unison type signature: `helloWorld : HttpRequest ->{Exception, Log} HttpResponse` which include Abilities

Abilities is a unique feature of Unison. It's how we model effectful code. Read more here: www.unison-lang.org/docs/fundame... 5/7

The Unison signature `List.map : (a -> b) -> [a] -> [b]` which includes type variables and a lambda argument

Lambda arguments work with type variables too 4/7
