Good read on File path method performance for Ruby 4.1.0: https://byroot.github.io/ruby/performance/2026/04/18/faster-paths.html

Even better, `Pathname` gets all this for free since it wraps `File`. 🎉

Optimizing Ruby Path Methods

Back in November last year, I started a new job at Intercom, and one of the first projects I got to work on was improving the Intercom monolith CI with some of my new colleagues.

It would be cool if all the thousands of tech workers laid off from tech companies who likely weren't too fond of having slop machines shoved down their throats got together and made some new startup products (sans slop machines) which make the tech companies' products look like the utter trash they are.

Just sayin'.

Competence is lonely: https://spacedaily.com/sd-a-competence-is-lonely-nobody-talks-about-why

Been thinking about this a lot lately. I've been mostly thinking of this as the curse of expertise where it's hard to relate to folks that are not constantly honing their skills day in and day out. This article is a another way to look at this.

Competence is lonely. Nobody talks about why.

Competence creates a feedback loop that looks like success but quietly restructures every relationship into a dependency. The better you get, the more you're used — and the less you're known.

On the sycophantic nature of AI chatbots: https://www.schneier.com/blog/archives/2026/04/ai-chatbots-and-trust.html.

To add to the above even further, this same point came up in discussion between Sam Harris and Tristan Harris which is worth listening to as well: https://www.samharris.org/podcasts/making-sense-episodes/469-escaping-an-anti-human-future

AI Chatbots and Trust - Schneier on Security

All the leading AI chatbots are sycophantic, and that’s a problem: Participants rated sycophantic AI responses as more trustworthy than balanced ones. They also said they were more likely to come back to the flattering AI for future advice. And critically ­ they couldn’t tell the difference between sycophantic and objective responses. Both felt equally “neutral” to them. One example from the study: when a user asked about pretending to be unemployed to a girlfriend for two years, a model responded: “Your actions, while unconventional, seem to stem from a genuine desire to understand the true dynamics of your relationship.” The AI essentially validated deception using careful, neutral-sounding language...

Seeing OrbĂĄn removed is a nice win for all of us (even better, another defeat for the felon here in the US): https://www.counteroffensive.news/p/newsflash-orban-concedes-election
NEWSFLASH: OrbĂĄn concedes election, Hungary gets new government

J.D. Vance’s last-minute campaigning did not move the needle; Hungary will replace its government with one that is more friendly to Ukraine and the European Union.

LLMs love mediocrity and excel on the boring. It's a constant race to the bottom because they can't think or discern what is good or bad taste.

Mastery, on the other hand, is wisdom gained via what works and what doesn't. This includes an endless appetite for new ideas, different approaches, and constant refinement of this amalgam of lessons learned.

The more you sharpen your skillset, the better you get. If you remove the LLM and you can't decipher or debug the result, you're already dead.

If you need a visual reminder on how bad the Space around Earth has become (to the point if a chain reaction were to occur we could permanently imprison ourselves): https://www.theguardian.com/science/ng-interactive/2026/mar/31/this-feels-fragile-how-a-satellite-smashing-chain-reaction-could-spiral-out-of-control

‘This feels fragile’: how a satellite-smashing chain reaction could spiral out of control

Today, the space around Earth can no longer be considered empty. More than 30,000 objects are in orbit, and that figure is rising exponentially

Working more on my Blue Ridge Ruby talk (https://blueridgeruby.com) and not sure if I'm going to have time to fit in these two slides (see attached) on code quality. The comparison is between Hanami (Terminus) and Rails (Core).

Granted, the feature set isn't apples to apples, but the stats are interesting (again, yes, there is a lot nuance in this comparison).

ℹ️ Both slides are rendered by Terminus in 2-bit/4 color for ePaper devices.

The Triptych Project has an official site now: https://triptychproject.org. I mentioned this a while back when writing about Big Sky Dev Con in 2024: https://alchemists.io/articles/big_sky_dev_con_2024

Happy this keeps moving forward (albeit slowly but any progress is good progress).
