DDD events are fantastic and DDD South West is especially so because Bristol is a delightful city - and their CFP is open, so get those talks in now and hopefully see you in Bristol in May!

I'm pretty much defaulting to F# for my domain code nowadays, C# is still less friction for infra, but once you get used to the ergonomics of F# to describe business rules, it's difficult to go back.

Yes, quite. It's the biggest scandal of this administration, so far, probably. It's an average Tuesday under Johnson.

I wonder... would there be any interest in some F# event / (un)conference in 2026?
I always wanted to do something similar to F# Creators Workshop (which @dsyme.bsky.social organised years ago in Cambridge) or Elm Camp (which has been for last couple of years)

Happy New Year! Rewatch our #VDDD session with Thomas Ploch on "What is an Aggregate?". It sparked a great dialogue on this core DDD pattern. Clear up perceptions & learn how to teach it. Watch on our site: buff.ly/Zwatr5x Or listen as a podcast.

💡 "We listen to what the business wants and translate that into quality software"

If you describe DDD to someone outside of software development, they might assume all software is designed this way, but in reality, it's not!

Been working with Typescript, Hono, Zod, and friends for the last couple of months. It was "interesting" but not particularly "enjoyable". I'm not the target audience for a language like Typescript - I'm too demanding and get frustrated really fast dealing with its shenanigans.

Hey #fsharp, what we do with #FsAdvent this year? sergeytihon.com/fsadvent/ Do we have 24 F#ers ready to participate?

The quote "All models are wrong but some are useful" should not be read as an excuse to stick with your model. It's a call to actively search for more useful models.

We'll know 'gold standard' apprenticeships really are 'gold standard' when politicians think their own kids should do them rather than getting a degree.

I saw Hillsborough for the first time in over 25 years, plus Bramall Lane, during my visit to see friends in Sheffield today. I still have mixed emotions about my seven years living in the city in the 90s.

If the government wants economic growth it must bring essential industries into public ownership Successive governments clobber households and small businesses by hiking interest rates to manage inflation, but don’t inconvenience corporations.

England nationalized rail passenger services lease carriages from rolling stock companies (ROSCOs).

87% of rolling stock controlled by 3 Luxembourg companies.

Paid £1.282bn dividends in last 3 yrs. Not taxed in UK.

Privatization has hollowed out the UK - Taxes lost, it is all about exploitation.

I looked at it in 2023 when it was pre-v1. If I'd had the chance of using OTP, I'd have tried to use it instead of erlang or elixir. Very similar to F# and elm. Nice community on Discord.

No, Your Domains and Bounded Contexts Don’t Map 1 on 1. It sounds clean and logical, but it’s wrong. Read about it in my latest article: verraes.net/2025/08/doma...

In fact, most of the ire you see against "object orientated code" is just ire against procedural code disguised as OO-code.

And of course, yes, that stuff is bad.

I suspect this is gonna open up a whole new dimension of resilience that we’ve been avoiding so far

(Also: the balkanization of the internet looks more and more likely by the day…)

Yeah it is! #pusb
