Curious as to how the Β£4,166,666.67 figure was arrived atβ€”a clean two thirds of Β£6.25m. I wonder what cost Β£6.25m of which this was considered 2/3 of the work?

Reflecting on the National Police Service – Andreas Varotsis So we’re doing this again…

So it looks like the government is announcing a National Police Service. Again.

It's one of those ideas that seems perfect from the outside, but yet we never seem to be able to get right.

It got my brain whirring, so I wrote up some reflections.

Interface failure is leadership failure Thousands of support requests rained down on our teams for the second autumn in a row.

How many govt services end up crocked, despite the efforts of skilled teams. (Policy and delivery being treated as separate. Shared platform cosplay. Leaders rotating off every 2yrs.) medium.com/@veroj/inter...

Lessons learned after 7 months at NHSE Not what I expected but in a good way.

My sense is that the Test and Learn movement in the public sector anchors much more on β€œbuild-and-test” than β€œdescribe-and-defend” as this essay sets them out… possibly to its detriment?

i agree! interesting that software formalises the "doctrine" part into a job role whilst everyone else has the job of balancing doctrine and context all day, decision by decision

You can't design software you don't work on --

β€œYou want your structural engineers to be drawing, not laying bricks, after all. I don’t know if structural engineering works like this, but software engineering doesn’t. In practice, architecture advice often has to be ignored by the people on the ground.”

10 lessons from 2025 Technology & identity in GDS and the NHS

I think the real lesson to draw from Palantir's many contracts is that government has on the whole so successfully driven away talent that those who show up capable and incentivised to engage with the real problems seem like manna from heavenβ€”& worth the ££££ and the lock-in. We should look to that!

Whereas a module that Palantir chooses to extract and add to their platform is just proprietary software. It's clever: they've harnessed the network effects of a open-source like ecosystem with a completely closed commercial model. Good business! And walled gardens surely have advantages.

That irreducible difference is the space where the design system and friends enable us to play very productively, and those assets are ours.

These are imperfect means to capture "solutions". But there's an irreducible difference between being solving one problem and having a generic solution to more than oneβ€”indeed the latter makes for the bad old consultancy model ZS contrasts unfavourably with Palantir's.

08.12.2025 18:18 πŸ‘ 0 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

ZS observes that for "indie consultants" "there’s no one extracting the patterns. The knowledge compounds in their heads... but it doesn’t get productised. It doesn’t create leverage." We do have that though: open source, the design system, the service manual.

DWARF support for macOS and Linux by joelreymont Β· Pull Request #14369 Β· ocaml/ocaml DWARF v5 Debugging Support for OCaml Native Compiler This PR adds DWARF v5 debug information to the OCaml native compiler, allowing proper source-level debugging in GDB and LLDB. What's Impleme...

One of the many joys of using AI for programming is the creation of huge PRs on complex topics that the authors barely understand, but still suggest "because they work". Here's a great example from #OCaml github.com/ocaml/ocaml/...

Kudos to OCaml's maintainers for handling this so gracefully.

This really resonates. Meetings are the synchronisation penalty public servants pay for an overwhelmingly synchronous, distributed system of management. The β€œmeeting culture” is not optionalβ€”it expresses a cultural void where autonomy can’t flourish.

A highlighted quote: β€œIn the world of thick construction, objective functions and thus meanings are constantly debated, negotiated, and co-constructed; objectives and meanings are multiple, overlapping, and at times contradictory. In the world of thin construction, overwhelming powerβ€”the ability to impose an objective functionβ€”leads to semantic power: the ability to impose meaning. β€œ

what a brilliant essay. amongst many other things, i’m definitely having β€œthick” and β€œthin” construction🧎

This fantastic paper "proposes a vision of AI that embraces local vernaculars, the multiplicity of objectives, the responsibilities that come with producing persons, and the potential of instigating rather than circumventing political contestation."
