So the rabbit hole tonight started here: bugs.ruby-lang.org/issues/22111 The question is how in the world do we pattern match in Ruby against String keyed hashes from things like JSON.parse? The issue proposes one way, I mention another at the bottom as a comment.

When everything is on fire, nothing is on fire. Where do you start when every problem seems intractable? By drawing a map. baweaver.com/writing/2026...

The sheer number of observability and related docs, books, conf talks, and articles I'm pulling together for the next Ozymandias article.... Cartography of a Ruin will cover one of my strongest opinions: You cannot "fix" what you cannot measure and prove.

New RubyGems.org design 👀

Hanami 3.0 wouldn’t be so full of goodness without the support of our sponsors. Rubyists deserve choice, and these fine companies are helping make it happen. Thank you to @mike.contribsys.com, @baweaver.bsky.social, @honeybadger.io, @fastruby.io, @appsignal.com, and @serpapi.com!

Shelley wrote about a king whose monument outlived everything it was built on. I've spent 15 years inside Rails monoliths that did the same thing. This is the first post about what to do when you're standing in the ruins. baweaver.com/writing/2026...

Something I should make _very_ clear while writing some of what I have lately like "Rails the Sharp Parts" and soon to be "Ozymandias on Rails": For zero to one Rails has _substantial_ value in getting people started, and for a vast majority of shops the concerns I note may never manifest.

So what am I considering writing up next? Well.....

I don't like to bury ledes, so when people ask me about polymorphic relationships my answer is simply: Don't. baweaver.com/writing/2026...

For those who haven't caught it yet, I've moved all of my writing to baweaver.com now: dev.to/baweaver/mov...

XKCD references are apparently an age signifier now 🥲

What are people loving for desks these days? My old ikea desk I got a decade ago is showing its age. Was about to swap 2x 4k Dell Ultrasharps for a single ultra wide considering TB5 + Mac + multiple monitors = 💀 and the ikea desk wouldn't hold up to the potential weight.

One of these days I need to learn Rust.

What if, by trading 1% correctness, you could count billions of items all within kilobytes worth of space? Well that's HyperLogLog, and as a non-bit-enlightened Rubyist it was a trip figuring out how it worked and how to explain it. baweaver.com/writing/2026...

This HyperLogLog article is a monster, but definitely forcing me to learn a lot more about bit manipulation and probabilistic structures. Rewriting the intro section to lead with strings instead of straight bits to soften the ramp more.

The problem with optimizing indexes is if you don't control every query, and another team goes and writes an unoptimal variant in their code. You, of course, will not discover this until weeks later in an outage. baweaver.com/writing/2026...

How worthwhile is standard.site integration for a blog today?

Next up, probably the single greatest cause of Rails-related SEVs and outages I've seen across now 5 Rails monoliths at 5 different companies? Callbacks. baweaver.com/writing/2026...

Next on our list of sharp parts: SQL indexes in Rails. baweaver.com/writing/2026...

One thing I try to remember: I am where I am because of others. I became myself through the people who taught me, challenged me, loved me, forgave me, and gave me chances before I knew how to deserve them.

Seems I need to read more into standard.site?

Finishing off a few articles for Rails: The Sharp Parts on indexing and callbacks, but spoilers for the callbacks article: Don't use them for any domain or business logic if you value your sanity once the app gets big. Implicit magical coupling that's not obvious causes so many danged issues.

The frequency with which I hear some amazing new music only to discover momentarily later that it belongs to a gacha game is too danged high. ....now excuse me while I queue up Genshin Impact music that has no right being as good as it is.

Now we're onto streaming and external sorting: baweaver.com/writing/2026...

Trying to make an article for hyperloglog and making that accessible has been a jib and a half. I think I may defer to substrings for intros and swap to bit manipulation post intuition building.

Took me a bit to pull this one together, but the first article in "Rails: The Sharp Parts" is out around locking. Admittedly my knowledge here was not as deep as I'd have liked it to be, so this forced me to do a lot more reading and research. baweaver.com/writing/2026...

bugs.ruby-lang.org/issues/21720... It'd be nice to have a core version of a Heap in Ruby.

Anyone happen to know why Ruby doesn't have a native Heap datastructure?

Bundler supports cooldowns now! Really great work from the RubyGems and RubyGems.org teams!!

I was working on content for algorithms and maths, but in doing so I found a more generic starting place on some things that I feel may be missing from Enumerable and the thought experiments around them. This one starts with two-pointers and windows as a concept. baweaver.com/writing/2026...

CA ballot is done, into the mailbox it goes.

Who do I know that's a committee on Sinatra?

I have a rule when approaching any larger-scale project with AI that I tend to call 80/20: 80% deterministic verifiable code, 20% AI to glue together the last mile.
