Doesn’t feel very personal
Screenshot of an email, cropped to just the subject, salutation, and first line of the body. Text reads:

“Participate in the AI-DMI Survey 2026

 
Dear %%FIRST NAME%%,
 
I am writing to personally invite your”

One time I gave a presentation on wine data analysis and I claimed that a rosé was a mixture of red and white and afterwards a person came up to me and yelled at me in French

For the last 2 years I have been tracking a generational change in the nature of software development, and I think I've finally decided where all of this turmoil is going to end up. It's good news, but not for everybody. seldo.com/posts/we-are-all-product-…

We are all Product Engineers now | Seldo.com
Agents are eating the software development lifecycle from the bottom up — code generation already gone, review and ops following fast. What remains is figuring out what people actually want, which can't be automated or scaled. That job is called product engineering, it pays $240k, and nobody's training for it.

I’ve gone from AI optimist to someone who is genuinely depressed by it all. The AI slop posters in every shop front are aggressively bland. People send me emails they haven’t even read. Customer support, barely human in the first place, is now 100% AI. I guess I can write good-ish code faster?

How long until it becomes socially acceptable to say “this looks like AI slop, I’m not reading it” ?

Trying something new to reduce the chance of AI prose ever leaking into my own writing. My LLMs now speak like a HK-47 hunter-killer droid. It’s such a clipped, hostile, outlandish style that I’m never going to use it to talk to another human being. And sometimes it calls me “meatbag”

All this talk of what it means to be a data scientist in 2026 is silly. A data scientist is someone who extracts data from XML files. That’s always been the definition and always will be.

One thing they don’t tell you about home ownership is just how much you’ll appreciate exposed utilities. I want every single pipe and conduit above ground, visible, and repairable

Vibe coding feels like I’ve been given a high-interest credit card with no limit. I get so much code written! And then I look at the actual code and I go “oh no… oh dear god no…” I saw it described once as “patch-on-patch-on-patch” and that’s exactly what it is

A new Fehervari book! I’m not even reading the blurb, this is an instant pre-order for me

LLMs gobble up and regurgitate marketing material with absolutely no scepticism at all. Ran into two situations today where it claimed things to be true just because corporate press releases said so.

These are the models I was most proud of painting in 2025. Horses are bloody hard to paint and I think I actually managed to capture that musculature here. And I’m finally starting to get value gradients right. (Kurnoth’s Heralds, Warhammer Underworlds)
Three painted plastic miniatures. Centaurs with red armour on stony oval bases.

This whole exercise has been a massive confidence boost, seeing the LLM struggle. ME: “Use a Tweedie distribution for the GAM” LLM: “Got it boss, one Poisson distribution coming right up”

Programming tip: never type out a 10-character command when you could instead press the up arrow for 5 minutes until you find that command in your history

Once again playing Elden Ring. I found out that, according to the community, the all-strength with big weapon build is called “unga bunga”, but if you split strength and intelligence it’s called “I unga therefore I bunga”

There’s a deeper skill that goes beyond specific technical expertise: can you articulate a problem you are facing with words such that others can understand it? You know the folks who just say “it’s not working” and give no details? They can’t prompt.

<rant> I can tell when a candidate is using an AI assistant in an interview. It’s obvious and insulting. It’s also incredibly common now. I’m at the point where if I saw a typo in a resume I would consider it a positive.

Seeing a typo or an awkward phrasing in an email is like a breath of fresh air. A human being wrote this! This is an artisanal, organic, free-range email! I’m going to give it extra attention.

Talking to some undergrads tomorrow about the why no one actually pays us to type model.fit() and asked them ahead of time to submit answers to a "trivially easy" data problem Fun to see the results come it, wild to know how many business run with a not dissimilar fog of war

I watched Theroux’s manosphere documentary followed by a documentary on an eccentric Icelandic man running the world’s only phallological museum, and it felt like the message for men was “fill your heart with hate, or fill it with weird hobbies”. And the hobbies route looked so much healthier

Painted this one up as a gift. Tried to make the fire reflect on the armour and terrain
A photo of a painted Warhammer 40K miniature. Green space marine of the Salamanders chapter, infernus marine. The model is equipped with a flamethrower. The flame is modelled and painted yellow and orange, with orange reflected back on the space marine’s armour.
