I wrote a deep dive on CIDs, the self-describing cryptographic fingerprints behind every record, blob, commit, and Merkle tree node in ATProtocol. Part 1 covers the history, the encoding primitives, and the specific constraints ATProtocol applies.

We don't know who struck first, us or them. But we do know it was us that scorched the back button.

alt-text or it didn't happen.

now all the texts have the aroma of sand dream, those against it type daily of what it is not. the rest are a chorus they live a duet, a golden age of punctuation that keyboards forgot.

A group of volunteers have been running @nhshackday.com since 2012. In a crazy world, it is all about coming together with common purpose to solve problems in our health service. Please reshare this post about #30 in Cardiff Mar 21/22. We would love to have you join us. ti.to/nhshackday/3...

I know there are a LOT of 'Clinicians Who Code' out there - but there doesn't seem to be any single place on the web to go and find them... Does anyone know of 'the' place? For now I've created a forum section in OpenHealthHub for them - please do share! openhealthhub.org/t/coding-too...

Periodic shout-out to @stechlab-labels.bsky.social for an excellent labeler. Even false positives (I too share links 5x/day for nonspam reasons!) are useful, really ups the game & trains users.

The principles behind indiweb (https://indieweb.org) and open source are, it seems, more important for nation states and public institutions than they are for individuals

"night-bus factor of 1" measures the risk to your project if you fall asleep.

"If a vulnerability has been public for two years and you have not been breached, the market has spoken" wise words as always

incantation upgrade! @andrewnez.bsky.social taught git to be package dependency history aware. ask git the history of a dep, who added it to the repo, when was it last upgraded. this is very good.

interoperability is a lot more important than decentralization

The NHS "owns" the Canonical Data Model (CDM), the interface to the Federated Data Platform that all existing systems are to integrate with and that new systems should build on. This is what the CDM interface looks like today. github.com/nhsengland/f...

Anti-fascistic software is made possible by pro-labor licensing. I've been trying to write this piece for years. Every time I get started I'm just overwhelmed with paralyzing visions of the FOSS commentariat accusing me of WrongThink. But I'm tired and we urgently need to get our shit together.

“Adversarial poetry.” Love this. Obvs.

absolute highlight of the week was the @inkandswitch.com meetup and talking to @wolkenmachine.bsky.social about his work on programmable ink, and catching a wild @expede.wtf and @pvh.ca too! That team remains brilliant, radical, and decent in equal measures.

Despite the vast sums spent on GP and hospital IT, we're not even able to losslessly maintain a single patient's digital clinical record for their own direct care for their lifetime without degradation. Join us, to help address this issue. www.tickettailor.com/events/dpc/1...

Lambeth got us mutually amending an EHCP via mailing .doc files between many parties and this is absolutely not a viable mechanism for tracking and merging conflicting edits.

from server racks to soundsystems

Trying to map the many contracts the NHS has with software companies. In theory there are APIs for this but so far the onboarding has been "email this private supplier for an API key" (Find a Tender API) and also "ask permission for each resource you want to access and wait for approval" (NHS ODS)

Server Charms are tiny, portable microcontroller setups made with recycled vape batteries. They create their own Wi-Fi network, inviting curious people to connect with their devices where a captive portal opens, leading to small webpages. codeberg.org/actinomy/ser...

A few ideas on what "good software" (not "good code"!) is, touching ethics, interop, commercials and functionality 🧵

"mandatory functional cookies" are only to be used to keep me in a meeting, not to show me a blog post.

Several current and former NHS staff have told me similar, angry stories about what happens to our old health records after the contract for a new, incompatible IT system is signed. It turns out proprietary storage formats are a problem: oli.zilla.org.uk/2025/10/20/w...

On my way to @openehr.bsky.social's EHRcon. An adventure to find the open standards people doing the work.

plz can someone study mechanisms for safe back pressure in NHS primary care? disabling web based contact forms outside of GP hours seems unhelpful. disabling them after exceeding a maximum number of requests, on the grounds of "safety" sounds like a veil over rationing.

3 themes from #HETT conf from software vendors who sell to the NHS about adopting open standards 😿 "why? what's in it for us?" 🫂 "the centre needs to bless a standard so i don't have to convince my boss" 🌞 "we already do openEHR. the clinical domain modelling is done for us, we focus on the UX."
