Gearing up for something new.

[Andrej Karpathy @karpathy]

Expectation: the age of the IDE is over
Reality: we’re going to need a bigger IDE
(imo).

It just looks very different because humans now move upwards and program at a higher level - the basic unit of interest is not one file but one agent. It’s still programming.

Stephen Colbert just took a flamethrower to Trump’s censorship circus.

While Jimmy Kimmel’s studio gets stripped bare under pressure from Trump’s FCC chair, Colbert claps back, animated and unapologetic.

Late-night resistance is alive. For now.

Shopify's Admin is one of our largest and most complex apps, powering 67 million page views daily — and now it's 30% faster and AI-Ready. 🏃🖥️

How? By rebuilding the architecture with @remix_run. 🪚 Learn more in this post by @CCBCodeMonkey:

Love this urgency. Ambitious build energy is how Canada wins. More homes, better rails, stronger economy. LFG.

BREAKING: Apple just proved AI "reasoning" models like Claude, DeepSeek-R1, and o3-mini don't actually reason at all.

They just memorize patterns really well.

Here's what Apple discovered:

(hint: we're not as close to AGI as the hype suggests)

Shopify just launched a racing game built in threejs and React (R3F).

No physics libraries. No raycasts.

Not vibe coded. But all vibes. ✨

Shopify: The Boring Edition.

We focused on the hard and unsexy work of nailing the basics, getting all the parts of Shopify to work seamlessly together, and run at tip top performance. You've got to sweat the details.

Some of my favorite updates 🧵

really nice piece of shopify infra just open sourced

A order on @SaltandSundry just tipped Shopify over the 1 trillion(!) in cumulative GMV.

Monumental milestone for us. A beautiful small business run by Amanda McClemens in DC. Couldn't have been a better example of what makes Shopify special: https://t.co/w1qUo7zuji

This could be summed up in one word: care.

You need to care. Caring is the bare minimum.

Sunday rant.

For software engineering, my sense is that the phrase “premature optimization is the root of all evil” has massively backfired. Its from a book on data structures and mainly tried to dissuade people from prematurely write things in assembler. But the point was to free you up to think harder about the data structures to use, not leave things comically inefficient. This context is always skipped when it’s uttered.

Not all fast software is world-class, but all world-class software is fast. Performance is _the_ killer feature.

If you are in engineering, here is a fantastic anecdote. I refer to this account often. It’s a bit subtile, but the implications are massive-

It’s an account of how SQLite became 50% faster, not by doing one specific thing but hundreds of small ones.

SQLite is everywhere today because of this work.

We need the engineers in all companies fight for this more. Product leads are not the right owners of the end performance of the software. This needs to be encoded in the professional pride of the software engineering discipline. Leaders in companies need to encourage it and hold engineering accountable. It’s simply not ok to fritter away the performance of the products for random reasons.

Every user of your products cares exactly as much about latency as engineers do when typing in their terminal. They just don’t have the words to describe what they don’t like about the experience and neither should they.

[Matt Pocock @mattpocockuk]

JavaScript's new 'using' keyword is awesome for mocking in tests.

It automatically disposes the 'mock' when it leaves scope. 🤯

No more beforeEach/afterEach...

Let me present you this year’s BFCM globe! The team has absolutely outdone themselves. It’s gorgeous.

Shopify‘s in-office keyboards are 👌

All details matter.

@ShopifySupport Merchants, we've got your back.

I think people underestimate the power of a meeting free Wednesday

[Mustafa Ali @mustafa01ali]

Thrilled to see our work get featured in the iOS AppStore!
