Returning To Rails in 2026 I love a good side-project. Like most geeks, I have a tendency to go down rabbit holes when faced with problems - give me a minor inconvenience and I’ll happily spend weeks building something far more...

Mark and I worked together when I first picked up Rails a couple of decades ago, kind of a heart warming read hearing him seeing its praises having rediscovered it.

I don’t know what is Apple’s endgame for the Fn/Globe key, and I’m not sure Apple knows either The origin and the evolution of the most confusing modifier key

I have not paid a ton of attention to the uproar over RTO policies, bc we are all in on distributed teams and not going back.

My impression (via social media) has been that these were shadow layoffs.

Last month I asked an investor why they are doing RTO. He said: "Retention, mostly. And morale."

How often do LLMs snitch? Recreating Theo’s SnitchBench with LLM A fun new benchmark just dropped! Inspired by the Claude 4 system cardβ€”which showed that Claude 4 might just rat you out to the authorities if you told it to …

New benchmark just dropped: SnitchBench by Theo Browne tests if LLMs will snitch on you to the authorities if you feed them incriminating documents and a tool that lets them send email, as seen in the Claude 4 System Card

Turns out they pretty much all will! simonwillison.net/2025/May/31/...

Thoughts on thinking β€’ Dustin Curtis I have been stuck. Every time I sit down to write a blog post, code a feature, or start a project, I come to the same realization: in the context of AI, what I’m doing is a waste of time. It’s horrify...

Thoughts on thinking by @dcurtis.com - dcurt.is/thinking

Depressingly accurate take.

The hardest working font in Manhattan A story of a 150-year-old font you have never heard of – and one you probably saw earlier today.

I think every designer should write a love letter to a font at least once in their lifetime.

This is mine: A 150-year-old font you have likely never heard of, and one you probably saw earlier today.

Building a (T1D) smartwatch from scratch Documenting an attempt to build a single-purpose smartwatch.

As a dad of a 9 year old T1D who's been round the houses with watches, watch software and the tech politics that have us not truly own that screen real estate on our wrist I'm incredibly impressed with this DIY project by

The Ultimate Tiramisu Recipe
The Ultimate Tiramisu Recipe YouTube video by James Hoffmann

It's finally done, the Tiramisu recipe is here: www.youtube.com/watch?v=o3AM...

As recipes go, this is reasonably nerdy - but optionally nerdy too. Somehow, after literally hundreds of tastings... I still quite fancy some tiramisu.

If C major is likened to high fructose corn syrupβ€”simple, ubiquitous, and easy to digestβ€”then F#13sus4 could be compared to a complex craft cocktail with unexpected yet harmonious flavors. Here’s why:
	1.	Complexity:
F#13sus4 consists of:
	β€’	A root (F#),
	β€’	A suspended fourth (B, replacing the third),
	β€’	A dominant seventh (E),
	β€’	Extended tensions like the ninth (G#), eleventh (B again), and thirteenth (D#).
This makes it a richly textured chord, demanding nuanced understanding and careful voicing.
	2.	Ambiguity and Color:
	β€’	The suspended fourth eliminates the major/minor distinction, creating a suspended tension that resists resolution.
	β€’	The extended upper partials (9, 11, 13) add layers of emotional and tonal complexity.
	3.	Rarity:
Just as a craft cocktail might be appreciated by connoisseurs, F#13sus4 is less common in conventional music and more prevalent in jazz, fusion, and other sophisticated genres.
	4.	Depth and Sophistication:
While C major offers immediate gratification, F#13sus4 engages the ear in a deeper, more layered experience, akin to savoring an intricate, perfectly balanced drink.

In short, F#13sus4 is rich, nuanced, and rewards those with a taste for the unexpected and sophisticated.
