GDS weighs in on the NHS's decision to retreat from Open Source

· 9 comments · 900 words · Viewed ~5,078 times


Guidance. AI, open code and vulnerability risk in the public sector. Guidance for safely publishing source code in the open, and reducing the risk of AI-accelerated vulnerability discovery.

Within the UK's Civil Service you occasionally hear the expression "being invited to a meeting without biscuits". It implies a rather frosty discussion without any of the polite niceties of a normal meeting. In general though, even when people have severe disagreements, it is rare for tempers to fray. It is even rarer for those internal disagreements to spill over into public. Which is what…

Talking Contact Tracing at FOSDEM

I was delighted to be invited to speak at FOSDEM. And I was not at all intimidated to be speaking on the cavernous Janson stage. The audience were lovely, asked interesting questions, and - most importantly - laughed in all the right places 😅. Regular readers will recognise this as being an updated version of the talk I gave at EMF 2024 - feel free to watch that one if you want to see if I've im…

Pop up notification saying the NHS covid app is shutting down.

This is a retropost. Written contemporaneously in 2020, but published four years after the events. It's May 2020 as I write this. I'm typing to capture the moment. Right now, I've no idea what the impact is. This is the exact moment, on Thursday May 7th, I hit the Big Red Button - three of them! - to open source the UK's COVID-19 Beta test app. …

Drinking Champagne with the Secretary of State

Selfie by Matt Hancock, featuring some of the team behind NHSX. I am in the background.

This is a retropost. Written contemporaneously in February 2019, but published much later. My life is weird. Again. Looking out over London from the top floor. The Eye is glittering and the Palace of Westminster is glowing. Someone pours me a glass of (very expensive) champagne, as the Secretary of State laughs at my witty bon mot. Is this my life now? People of distinction and influence…

The Digital Covid Test That Nearly Was

Photo of a lateral flow test.

These are notes that I wrote during the height of the Covid-19 pandemic. I've published them a few years later. By now, you're probably sick and tired of shoving a swab up your nose and / or down your throat. You've grown blasé about the little medical marvel as it reacts to whatever antibodies are flowing laterally. You don't even bother reading the paper leaflet any more. Right? But that swab …

So, farewell then COVID-19 App

Pop up notification saying the NHS covid app is shutting down.

Today is a day of mixed emotions for me. The UK's COVID tracing app is finally closing. The app was, by any reasonable measure, a success. A team of experts at the Pandemic Sciences Institute at the University of Oxford and Department of Statistics at the University of Warwick estimate the NHS COVID-19 app prevented around 1 million cases, 44,000 hospitalisations and 9,600 deaths during its…

Three Things I Wish I'd Known About NHS Technology

Pamphlet for the New National Health service.

It has been a year since I stopped working for NHSX. A few weeks ago, someone reached out to me inquiring about a job there. They wanted to know what they needed to know before joining. As well as the normal moaning about the quality of vending machine coffee, I told them about three things which caught me off-guard when I joined. So, here for your edification, are three things I wish I'd…

Weeknotes: Vaccinated - Part 1

Me holding my NHS vaccination card.

I know exactly what I was doing on 9th April 2020. I was worrying about open-sourcing the NHS Covid Tracing app. I was worrying about tech standards for booking test slots. I was worrying if I'd ever see my family and friends again. I was worrying if the NHS websites would contain enough semantic HTML to be useful. I was worrying if the security of 3rd party sites was up to snuff. I was worrying…

Paul Mcgann as Doctor Who.

Well, that was a whirlwind! After 18-months at NHSX, my 6-month temporary secondment has reached its end. It's always hard when a job finishes. The secondment was twice extended, and that let me carry on defining open technology standards for the NHS. Now it is over and I'm a bit sad. The pandemic seems to heighten all emotions, doesn't it? I'm luckier than most. I'm still employed. The whole…

It will cost you £500 not to attend this conference

Two pigs talking. "Isn't it great that we pay nothing for the barn?" The other says "Yeah and the food is free."

A few weeks ago, I was asked if I wanted a free ticket to a conference about the health industry. The line-up of speakers looked pretty interesting, so I said yes. I speak at a lot of conferences, and sometimes it's nice to go as a guest. Even though I'd agreed, the conference organiser started with the hard sell. The location was at a famous sports club (yawn!) and we'd get a behind the scenes…

Week Notes - COVID19

Teamwork makes the dream work. A shoal of fish have formed into the shape of a large shark.

What started as a fairly ordinary week, quickly transformed into something extraordinary. Large swathes of NHSX were suddenly told to de-prioritise their day-to-day work and focus on COVID19 response. I probably can't talk specifically on what I've been working on, but it has been one of the most intense working weeks of my life. As is customary, here are The Good, The Bad, and The Ugly of my…
