If people weren’t so inherently kind and cooperative and striving towards building a better world, then Empathy Driven Development wouldn’t work

But it does! I’ve seen it do the impossible again and again. It’s my favourite secret sauce and it tastes amazing
Write code to make being human easier. Rip code out if it makes being human harder. Write code to make caring for each other easier. Rip it out if it makes caring for each other harder.

Empathy driven development has literally never failed me. It’s done me better than everything else combined

This is so real. One of my most unwavering beliefs is that humans are, at the core, good and want to do good things in the world

I know it can be hard to believe. Especially given the news right now, but it’s true. A few clowns don’t change the majority
like so much of any given ~discourse~ comes down to a quiet sneering assumption that people are awful and I cannot stand it

projecting your self-loathing onto everyone and everything isn't insight, it's a voluntary commitment to brain damage, choose better

“The neuron teaches us something uncomfortable: computation isn't a lens revealing neural truth—it's a filter that shows us only the biology that looks like a computer. Everything else gets discarded before we even begin our analysis.”

Fascinating read.

The two hardest problems in Computer Science are

1. Human communication
2. Getting people in tech to believe that human communication is important

The main problem with Big Design Up-Front is that most of what we *really* need to know lies on the feedback side of the development process. Without that feedback, it's all just guesswork.

FWIW, I've never had a year typify "You do not rise to the level of your goals, you fail to the level of your systems" more than 2025. Emotionally and energy wise --fires and fascism factored in -- I've never been more punched out. But I worked and lined up more work based on old habits saving me.

25 years ago, I encouraged dev teams to take a multi-dimensional view of their business goals, balancing different - perhaps competing - perspectives.

In 2026, I just hope they *have* a business goal and that somebody will tell them what it is.

That's how far we've come.

How I teach software design starts with a problem.

It's hard to find vegan takeaway round here. I keep forgetting to buy bin liners. I miss the best bands when they're in town.

Not "An app..." or "An API..." or "An agent..."

A problem.

Remember those?

I mean, it's not like we ran out of them.

4 principles of modular design:

1. One reason to change
2. Hides internal workings
3. Has swappable dependencies
4. Usage-driven interfaces

I'm adding a 5th:

5. Does what it says on the tin, and says what it does on the tin

It should be obvious what it does, and it should bloody well do it!

The teams producing reliable software are only able to do that because they test continuously.

Do you know what else they can do because they test continuously? Ship any time the customer wants.

Short lead times and reliability go hand-in-hand.

Long delays and buggy software likewise.

On the McKinsey report that "discovered" smaller dev teams are more productive...

I coined a term: "project heat"

I'd estimate how much it would cost with a team of 4 good devs. Then I'd compare that to the actual.

The difference is "lost to heat". I've seen > 99% on more than one occasion.

As 2025 draws to a close, my hopes "AI" was going to force more teams to address the real bottlenecks in development fade into the distance.

95% will just ship less reliable software, and take longer and spend more £ doing it. And users will be coerced into eating the costs.

Business as usual.

Dear listeners,

When the days feel narrow and the noise gets loud, try a song.
Not as escape — as evidence.
Someone, somewhere, once felt this too and made something that still holds.

If hope is hiding, it often hums first.

"Coding is no longer the bottleneck".

So what you're saying is that NOTHING HAS CHANGED.
