A project for this rainy bank holiday. An arduino robot! (Still in need of debugging.)
We went for a walk today, and everything was green and GLORIOUS.
This week's @tag meetings included:
•Updating the multi-screen window placement API, for ex: slides on one screen & speaker notes on other
•App history, so that forward & back buttons in a web app can navigate within the app instead of away from it
https://github.com/w3ctag/meetings/blob/gh-pages/2021/telcons/03-08-agenda.md
This week, we focused on our design principles in our @tag mtgs:
• Fast-evolving crypto algorithms in slower-evolving features
• Using more bikeshed syntax. (Yes, our spec-generating tool is called bikeshed. It matters what shade of blue that is!)

This wek’s @tag meetings included:
• WebXR hit testing, so you can cast a ray into the real world & return a list of intersection points for that ray against whatever world understanding the underlying system gathers

Paper: The epidemiological impact of the NHS COVID-19 App. 2021. Wymant, Ferretti et al.
"We estimated that for every 1% increase in app users, the number of infections can be reduced by 0.8% (from modelling) or 2.3% (from statistical analysis)."
Technical documentation for the #NHSCOVID19app’s risk scoring algorithm:
#OpenSource code for the #NHSCOVID19app:
• System & architecture https://github.com/nhsx/covid19-app-system-public
• Android https://github.com/nhsx/covid-19-app-android-ag-public
• iOS https://github.com/nhsx/covid-19-app-ios-ag-public
Vulnerability Disclosures: https://hackerone.com/nhscovid19app?type=team
The #NHSCOVIDapp is now also interoperable — compatible with other contact tracing apps across the UK, protecting users who travel to Scotland, Jersey, Northern Ireland or Gibraltar.
• The #NHSCOVID19app is continually improved; has had a series of updates since its launch in September 2020, including an update to the risk scoring algorithm to utilise Google/Apple's API Mode 2 which better estimates distance based on Bluetooth signal strength.
• Users have checked into a venue over 103 million times
• 253 venues have been identified ‘at risk’ after an outbreak since 10 Dec, triggering ‘warn & inform’ alerts to app users who had checked into those venues. A ‘w&i’ notification is different to an instruction to isolate
• The #NHSCOVID19app has been downloaded 21.63 million times, representing 56% of the eligible population (age 16+ with a smartphone)
• Research by scientists at @TuringInst & @UniofOxford shows for every 1% ⬆️ in app users, the # of coronavirus cases in the population ⬇️ 2.3%
New stats on the #NHSCOVID19app:
• Approx 600,000 cases have been prevented by the app since Sept
• Over 1.7 million app users across England & Wales have been advised to isolate by the app after close contact with someone who goes on to test positive
