After a year hiatus, my series on all things Ruby concurrency is back! This post digs into the interrupt mechanism in Ruby threads. These interrupts revolve around bit masks, so it's got some Ruby bit work as well! Expect more regular updates from now on 💃💃💃 jpcamara.com/2025/10/22/b...

Behold, an awesome list… of awesome lists! github.com/andrew/ultim... I found a couple good ones in the Ruby section: github.com/ayarotsky/aw... github.com/Darhazer/awe... Plus a few other lists of awesome lists… so does that make this an awesome list of awesome lists of awesome lists?

TIL a weird Ruby feature: Continuation. ruby-doc.org/3.4.1/Contin... > Continuation objects are generated by Kernel#callcc [...]. They hold a return address and execution context, allowing a nonlocal return to the end of the callcc block from anywhere within a program. 🧵 1/3

I recently moved my list of Ruby podcasts to Awesome Ruby Blogs (github.com/Yegorov/awes...) from my Ruby resources list (github.com/fpsvogel/lea...). It's quite a comprehensive list. And recently a very kind soul added RSS links!

I often find cool Ruby gems that I think should be more widely known. Here are some related to testing: github.com/palkan/n_plu... – RSpec and Minitest matchers to prevent N+1 queries github.com/kaspth/oaken – fixtures + factories + seeds for your Rails development & test environments 🧵 1/3

For the first time in a long time, I have a professional CV! (100% hand-coded HTML of course, and the PDF was itself printed from the HTML via a print stylesheet.) 😎 I'm looking to make a major impact on a fast-growing team with high-stakes full-stack architecture or design system planning […]

rubyapi.org is my favorite Ruby docs site. Its search uses a query param, so if you add a search keyword to your browser, you can search Ruby docs from your address bar! nedbatchelder.com/blog/202205/... For example `rb partition` would take you to rubyapi.org/3.4/o/s?q=pa...

Impressive: scope inline style tags with vanilla CSS. Implemented in only 16 lines of JS 😮 github.com/gnat/css-sco... I love that there's a README section titled "CSS Scope Inline vs Tailwind CSS Showdowns"

In yesterday's meeting, we started a book club on Polished Ruby Programming by Jeremy Evans. We talked about: - underused data types: Rational, Symbol, Set, Struct, Data - how SOLID principles never seem to come up in real life, e.g. code reviews - other topics recapped at bluegrassruby.club/posts

RorVsWild has great posts on Rails performance optimization: www.rorvswild.com/blog Also, this article and its sequel should be mandatory reading for junior Rails developers: henry.bearblog.dev/beginners-gu.... It would have saved me quite a bit of confusion a few years ago when I was starting out.

UnsuckJS is a handy list of JS libraries that make writing JS a better experience (even if by reducing the need for JS). unsuckjs.com It's the closest thing to a complete list that I've seen, if you include open PRs. Today I opened a PR with no less than 17 entries 😄 github.com/adamghill/un...

Reposting from Mastodon on here has always felt awkward to me, like I'm saying the same thing again to largely the same crowd… so, new approach: I'll post a weekly recap here of what I shared on Mastodon. Onto this week's recap! 🧵 1/3

For those who blame macOS Tahoe for bugs. Let me tell you how apps work in the country I live. Once, all users of the most popular bank got a push notification saying: "Bro, why are you bald huh?" Yes, they just tested something in production.

This list of web UI/UX guidelines is good, surprising since it's by Vercel: vercel.com/design/guide... It made me think back to my favorite UI/UX guides: - The Design of Everyday Things: www.nngroup.com/books/design... - Laws of UX: lawsofux.com/articles - 100 UI/UX Tips: vpon.me/hundred

The book Metaprogramming Ruby 2 explains something that I couldn't have articulated before. `module`, `class`, and `def` form "scope gates", across which local variables are out of scope. But you can "flatten the scope" by dynamically defining a module, class, or method: github.com/khusnetdinov...

Recently there was a discussion about using ivars directly vs. private accessors: www.reddit.com/r/ruby/comme... I've been using private accessors, but @davetron5000.com's take changed my mind. 🧵 1/2

🎄 2015 day 6 of #AdventOfCode in #Ruby: Amazing. A code golf solution in Ruby is twice as long as a solution that wasn't even intended to be golf, in the K language: www.reddit.com/r/adventofco... I feel like I'm passing by whole other universes. #ProgrammingLanuages

🎄 I'm doing past Advent of Code puzzles in Ruby: github.com/fpsvogel/adv... I'll be posting my TILs. Here's one. 2015 day 5: regex backreferences can replace a lot of manual string iteration. 🧵 #ruby
