Shout out to Schiphol, arrived for our flight 1.5 hours ago and not even got through the passport check. Super fun with a 3 year old child.

GitHub just finished ripping styled-components out of github.com. Result: 55% less time to server-render a page, 25% faster component init. CSS-in-JS makes you pay for styles twice: collecting them on the server, running JS on the client. Static CSS is *always* more efficient. Ship CSS.

Managed to do a bios update and then CPU and cooler upgrade without breaking the motherboard or anything else and that's pretty impressive if you ask me

Just read the words "only older readers will remember SASS and HAML" and I died a bit inside

People who want to stop giving 1Password your money: what are you using instead? I use it as a basic vault and not much more.

I remember a conference after party a decade+ ago where @johnresig.com was stood in the corner on his own because everyone (including me) was too shy to speak to him. Fwiw, if you ever want to talk to me at one of these things, please just do it. I'm also shy.

Yes parenting is hard but the good news is that my coping mechanism is buying too many model trains

Finally deleted my Facebook account today and it feels good

Every article about the inevitability of AGI

I am a 34 year old man and tomorrow a shed is being put in my garden solely for model trains and how good is that

If you want to know what parenting is like (for me at least) things got so tough yesterday that after failing to get my 2yr old to eat his pasta in a pub (meal with family), I had to walk out & have a cry in the car park. Sharing because no one talks about this stuff - especially not dads.

I can't put my finger exactly on it but Opus 5 and the new GPT 5.6 are just...too smart? Constantly giving dreadful verbose, unclear output and actually far far worse at generating anything useful.

Yep. If code was never the hard part, software wouldn’t be so goddamn buggy and broken. If “code” only ever meant thoughtlessly churning out the next endpoint, you missed the point entirely. blog.senko.net/code-was-nev...

Technology, like time, cannot be stopped in it's relentless march forward. Much as us old timers would like to slow down one or the other just a little bit… In light of that, Chrome 153 will come with an updated list of modern devices for emulation mode—with nice categorisation—thanks to @jackf.io

Hamilton on West End with Lesie Odom Jr...I don't know if any musical will ever top that

"Grok did it no problem" what a surprise can't imagine why that is

In my audits, reading the Performance profile is where people get stuck: the flame chart and waterfall look like noise at first I built an interactive guide to make them click, every figure is interactive, plus LCP, CLS, INP and the Insights panel perf.reviews/profile-guide #WebPerf #DevTools

Feels pretty good to have my phone download a 1.7gb Android update full of features I will never use

Asked AI on a whim to see if it could identify any reasons my unit tests felt a bit slow and sure enough - runner.test.ts: ~9.3s cumulative → ~0.15s. - All reported test durations: ~27.9s → ~8.3s.

Wayne Rooney live on the BBC saying his highlight of the half time show was the ending and then saying "it was crap" is the undoubted highlight of the entire world cup. Also he was right, wow that was bad.

Polymarket lets people bet on wildfires. Wildfires that those samepeople could easily set in order to win money on this illegal gambling site. Big Tech is organized crime.

This post is just...so, so, so good.

Apparently Spotify ship about 2000 AI changes a day or something yet they still can't make your downloaded content appear immediately if you're on very poor signal

All these products that let you run a fleet of AI agents and do 100 things at once are baffling to me; do we actually want this?! I know I can't do more than 1-2 things (with one primary focus) before the quality drops and my head can't keep up and think properly about the problem and solution.

Great piece, well worth reading, a teaser: "There's what modern software is actually capable of, and then there's the gargantuan pile of 'AI' hype, fraud, and bullshit ... hucksters lying to your face about the imminent arrival of omniscient, sentient, paradigm-rattling supercomputers."

Can officially add "V8 contributor" to my CV now :D

Best England performance of my lifetime, possibly? Wow 😳

Less is more, more or less. AI makes it easier than ever to add more, and faster. It’s tempting. But we might end up building things that don’t need to be built quantity over quality. Clarity will be hard to achieve. It doesn’t happen by accident.

Today's episode of Jack being proud of himself for conforming to an ultimately harmful stereotype of "being a man": I jump started a car for the first time! 😂

Posted this on a Sunday evening, so mentioning this again for those of you who had better things to do on a Sunday night than read this :D

Blogged about AI, loop engineering, token cost and motivation when giving AI advice. AI loops: who pays for the tokens? www.jackfranklin.co.uk/blog/who-pay...

The company that used the books I co-wrote to train its model without permission is weeping that China "brazenly" and "illicitly" extracted its Claude AI model's capabilities. I'm sending snorts and stares. www.bbc.co.uk/news/article...

I have to collect samples of my dog's poo for the vets and I think my life has officially peaked (The dog is fine, they are trying to double check something but no stress or concern!)

Huge +1. I spoke about this at a conference last week; be aware of folks who don't pay for tokens (like me in my day job, but I pay for my personal Claude usage!) telling you how great huge, multi hour loops are.

Signal boosting as this starts next week! Tell me what DevTools bugs the team should fix

This is me! We're focusing on a few areas next month and I'm leading the "Paper cuts" area. So spam me with your bugs, please - and please file them yourselves first so I can triage them internally 😁

This is an embarrassing image for the UK. A self-respecting British fox should be dragging Binface's contents out over the stage

Such a good article, more like this please correresmidestino.com/dont-you-jus...

Blogged! I wrote an ai-review skill & tool to let me review AI plans in the browser. I prefer working in the terminal but much prefer reviewing in a PR-style review UI. So I built it! www.jackfranklin.co.uk/blog/ai-revi...

LHR>SFO ✈️ for my first Google I/O! 🎉

Sneaking a giant screen into the flagshagger march is one of the funniest things @ledbydonkeys.org have ever done. "STAY HYDRATED" 😂🤣😂

Wrote a blog post about using Claude to track feedback and building a small skill and CLI to avoid huge inefficient markdown files: www.jackfranklin.co.uk/blog/claude-...

Excited to head up north for Developers Up North conf in June this year :) www.developersupnorth.co.uk

A good week ⛷️
