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

Remember 100,000 of us protested for trans rights in London 4 wks ago

We get more ppl every other week for Palestine solidarity in Cardiff than the fash had at Rhws. There'll be more ppl at Trans Pride Cymru today

But British "journalists" don't care about reporting our concerns. Just the racists'

Kind of fun to see straight forward, functional programming in #fsharp with Result types on every single event and @scottwlaschin.bsky.social style domain driven design process 8-9 million events pr minute on a 2-core 4GB RAM Azure Container App IRL.

Both! :)

Higher Kinds in C# with language-ext [Part 1] Version 5 of language-ext introduces the concept of higher-kinded traits. This series unpacks the implications of that!

Very interesting blog series from @paullouth.bsky.social on higher kinded types in C#. He's kinda (see what I did there) made an `M a` out of a `K<M, A>`.
It actually comes out reasonably smooth (but agreed that it should be in the language).

Mind blowing

Reddit post on r/technology about young people and AI: "I recently heard about a teacher who instead of trying to circumvent students using AI, which is impossible, she made assignments by going "ask ChatGPT to write a report on this subject, and then research how and why it's wrong". Not only did the students discover that ChatGPT is extremely wrong a lot of the time, it also lead them to realise that they should not use it as a primary source".

This is one of the best ideas I've heard in ages.

The problem with people that "vote for change" in politics is that change is uneven.

Bad changes are easy to make, and positive change takes time and perseverance because good systemic change is hard.

I'm sure there are counter examples, but it's why "brick through the window" politics sucks.

I used to enjoy reading posts on both of those sites. Sad that we don't have similar sites today.

Why F#? If someone had told me a few months ago I’d be playing with .NET again after a 15+ years hiatus I probably would have laughed at this.1 Early on in my career I played with .NET and Java, and even…

Normally you'd have to pay £££ for a conference ticket to get @rendle.dev and @davidwhitney.co.uk on the same programme. Or you can come along tomorrow night and see them both for free - our friends @accurx.bsky.social are even providing free drinks and snacks!

For me, one of the best definitions of Test-Driven Development comes from the paper "Mock Roles, Not Objects" by Steve Freeman, Nat Pryce, Tim Mackinnon, Joe Walnes.
