I can't find it now, but someone wrote something like "Saving time doesn't add to efficiency if it adds work for other people/team. That's just passing off your responsibilities." Efficiency is an org wide measurement.

Alongside the Ruby 4.0 release last week, I published charm-ruby over Christmas, bringing @charm.land's excellent terminal UI libraries to Ruby. A full TUI framework, reusable components, styled output, forms, markdown rendering, spinners, charts, and a lot more! Demos below ⬇️

In case of emergencies, keep your kitty close to your on-call bag. Alternatively: Sorry I can’t respond to that incident. Cat-blocked

I think Gmail is the antidote to any sort of perfectionism. Like, how is this old, ugly, confusing, low-functionality app based entirely on the browser so popular? Can’t even cmd-tab to it like a proper app. Sure “it’s free” but people also pay for it 🤷‍♂️

My favorite advice for blogging remains that you should hit publish while you are still actively unhappy with what you have written, because the only alternative is a huge folder full of drafts and never publishing anything at all

Starting to think this is the timeline we’re on

I got two Red Dot Design 🔴 award-winning presents for Christmas this year. They are a sure sign of a well-designed product and often favour smaller niche businesses. www.red-dot.org

Tiny Tim, WHO COULD NOT DIE, could not die. The solar system could die. Tim watched the embers of the exploded sun flicker out. Tiny Tim, WHO COULD NOT DIE, could not die. The galaxy could die. Andromeda crashed through the Milky Way. Stars shattered. The heavens quaked and burned. Tim endured.

We have a “nerd tree” with all sorts of Star Wars, Warhammer, and Lego stuff on it. I keep forgetting about this guy though!

Merry Christmas to the best the now deceased Irish Twitter had to offer. #Speirgorm

#rubyrelease30th I’d like to introduce Aliki, RDoc and docs.ruby-lang.org’s new theme 😄 railsatscale.com/2025-12-22-i...

Easing into Christmas with… my longest ever swim! 8km as 2x 400m + 12x 600m. I really tried to live up to this Ross Edgley quote on my t-shirt.

Listening to The Pretty Reckless’ Christmas on repeat: youtube.com/playlist?lis... “Where are you Christmas?” is funny but “Christmas is killing me” is the antidote to all that faux-sweetness

Son: Jake Paul has a broken jaw Me: Couldn’t happen to a nicer person … Son: but he’s not a nice person Me: Exactly. Good boy for knowing that

Ham, spiced beef and eggs for breakfast. Awesome time of year for getting that protein

#Ireland when it stops raining: un-fucking-beatable 🤩

I thought the light-hearted moment of today’s 5km swim was going to be me trying to”paddlehead”—swimming whilst keeping a paddle on my head. But I was outclassed by the instructor accidentally falling into the pool in front of a kid’s swimming lesson. Sublime moment of comedy!

This video series just launched, and the first guest is one of my dearest workmates, one of the best programmers I've ever met, and someone I always talk about when I try to explain how incredibly special some people I work with are: Jeff Hardy ❤️ dev.37signals.com/the-rails-de...

I kept clicking the button and I don't know if Slack is broken or it's trolling me. "Something went wrong. Please try that again." could easily be a summary of my year

Bought this book for my two mates’ babies for Christmas and I’m dying.

Over 40? Tonight’s The Last Night You Can Go On The Drink & Not Be Hungover For Christmas https://waterfordwhispersnews.com/2022/12/21/over-40-tonights-the-last-night-you-can-go-on-the-drink-not-be-hungover-for-christmas/

Ok but the big question is: are they the same machines?!

As is tradition, I’m using the time between finishing work and Christmas Day, to enjoy the festive sandwiches around #Cork. First up was Tonguetied’s Miracle on Monahan Rd.

Just casually sitting on the couch enjoying the fire and looked out the window 😱 🔥 😅 😌

It's that time of the year

Thinking that AI-generated code will go away because it's inferior to hand-crafted code is reserved only for those that still believe in Betamax. Quality ultimately doesn't matter as much as we might wish it did.

Here's Emil's 17 step guide to how he used VS Code agent mode plus Claude 3.7 Sonnet, Gemini Pro 3 and Claude Opus to build the new library - it's a fantastic case study in using LLMs for serious, prediction quality code (vibe engineering, not vibe coding) friendlybit.com/python/writi...

When you drift through some unheralded point in your 40s, you start accumulating actuarial risks. The odds of illness, heart attack, or the chances losing of a parent go up. But there is another risk- particularly acute for men. There is a risk you will lose your capacity for joy.

I thoroughly recommend reading all of Cory Doctorow's recent speech on AI skepticism, it's crammed with new arguments and interesting new ways of thinking about these problems pluralistic.net/2025/12/05/p...

Ruby’s biggest flaw is that it insists humans matter. Some people hate that. robbyonrails.com/articles/202...

You'd think us violating Irish neutrality in an apparent attempt to assassinate Zelensky by forcing his plane to crash would be bigger news. For the Irish for a start.

Re-reading Brook's No Silver Bullet in the age of AI is interesting. worrydream.com/refs/Brooks_... For a paper written 30 years ago, it's still quite relevant mentioning AI, expert systems and code generators.

My 17yo daughter has a music age of 75. > What have you been listening to?! > Deftones, Metallica, <looks sheepish> Stone Roses, The Smiths, The Beatles 🤣

Turned up at the pool without trunks or towel, drove home, drove back to the pool, then didn’t have enough time for a full session before the school swimming lessons. Smashed out a 1500m hitting a new PB time and a new 1000m PB split 💪 🥵 Ironically, the school didn’t turn up for their lessons 😖

Some people just want to be right, argue exhaustively about how right they are, and have everyone admit they’re right. Insufferable bores.

Rails tip: Use draw to break your routes into logical, modular files.

I really like this point and have seen evidence of it: when humans get confused or overwhelmed by complexity, it’s a signal to search for alternate solutions. AI just plows on, often in the wrong direction, without feeling this pushback. It doesn’t feel the pain obie.medium.com/ruby-was-rea...

The AI bubble burst 💥 will be the best thing to happen to AI because constraints breed innovation. Currently there are no real resource limitations, leading to inefficient models and no sense of what AI actually costs to use => low value use cases everywhere.

I’ve been saying this for a while: reimagining intelligence as language construction is SUPER interesting. We don’t need to represent a conceptual understanding that 1+1=2, we just need to statistically know that “2” follows “1+1=“. Genius! But I think language-as-intelligence will not lead to AGI
