Way to start the weekend. Calm before the storm. https://t.co/40cWkw0Q5X

A few photos from our recent trip to Thailand at https://t.co/ueacIKUK24 and https://t.co/vXk9HIIEKA. Special thanks to #ChallengesAbroad #FutureSenseFoundation and #ElephantNaturePark

Thanks @TomTom for demonstrating the limitations of real-world data.

Expected to announce ⇏ confirmation
Focusing on the positives: @educationgovuk testing the water via the media. Gathering opinions across society. Perhaps reflection will allow for changes to be made to the benefit of all.
Meanwhile, I sympathise with those caught up in this.

Exams may be replaced by ‘mini’ exams...

There will be more hours of daylight tomorrow than there were yesterday. Nights have been drawing out for the last week. Summer's on its way. https://t.co/34IaIqMBXs #Solstice

@nav07 @TomTom Given @TomTom's current poor show, am considering @Garmin 425 https://t.co/p9Fb0beYE3 @GarminUK

Three #tomtom watch strap failures. One #tomtom device failure. @tomtom not responding to communications, despite ticket ID.

@TomTom I have sent @TomTom a DM on 17th December and another DM on 21st December. Still awaiting support.

[Simon Levy @ttsjl]

@nav07 @TomTom Which one have you got?

[Simon Levy @ttsjl]

Biased sample

Definition: sample in which the method used to create it results in samples that are systematically different from the population.

Example: having to be physically present to vote on whether future votes require you to be physically present.

Footballers are tested twice per week. 15% of clubs have +ive tests in the latest round. What's the capacity for this frequent testing for keyworkers? Or throughout wider society as it's released from lockdown? #StayAlertSaveLives #traceandtrack Source: https://t.co/WZSqb8H35Z

@connieloizou @mathsjem @mrbartonmaths @atulrana @wacom Personally, I think there are limitations to all of these 'solutions'. I currently opt to write solutions on paper, and use the @microsoft Office Lens app to tidy up (available on iOS and Android). 2/2

[Simon Levy @ttsjl]

@connieloizou @mathsjem @mrbartonmaths @atulrana Are you after a new device, or something to 'plug in' to an existing device? If opting for a new device, think about what OS you want (Chrome/iOS/Windows). If you are after something to 'plug in', @wacom are pretty good. 1/2

Why is R currently so much lower in London, compared to the rest of the UK? What is going on here?

If the Alert Level is currently at 219,183.9, how can it ever return below 5?

Some cartoons are better than others. Good work xkcd. As ever. https://t.co/gO4S4TkFLT #StayHomeSaveLives

@nav07 @anitamassey86 @RoryStewartUK I wish the answer was 'yes'

A new era in the marathon, ushered in by shoe tech. In our latest podcast, we explore the “recalibration” of running performances (2:03 is the new 2:05, 2:15 the new 2:18), integrity & fairness, how the tech works, and what should be done about it: https://t.co/alXIIaJyGu
