@TsuiAllen I don’t see which you prefer? I feel the RPi implementation is really clean for modelling. Haven’t tried tynker recently. What are your thoughts?

@IanYorston London is special case regarding taxi culture. I wonder what the same survey in other uk city might be like.

I‘m not surprised by this. The resistance to technology is strong where replacement, not augmentation is concerned.

Made it to Spain for totality. Not quite @AJamesMcCarthy but pleased to capture some corona and prominences. Quite the experience. And turned out to be a good omen for son‘s results too. #grateful

[Alastair Vaan @BitbyBot]

@AJamesMcCarthy Thank you very much Andrew.

@IanYorston A concept captured beautifully by Diane Morgan in Ann Droid.

In fact programming is particularly good at teaching you how to think. Programs are literally built out of ideas. Which is one reason it's still a good idea to study CS in the AI era. It's still important to be able to think well.

What a pleasure to end up sat on a table all day with @mberry @suesentance and more talking AI education.

And thanks @Raspberry_Pi foundation for the invite! So much potential in this space.

Our breakthrough work on an analog optical computer points to new ways to solve complex real-world problems with much greater efficiency. Super to see this published today in @Nature. https://t.co/vjx8lYmze5

Quite a lot of Skye feels like Mordor, only with better food…

ICYMI: Earth’s sea ice reached a new low in 2025. 🌊🧊

Arctic sea ice cover reached its lowest annual maximum on record and Antarctic sea ice cover was the second-lowest on record in March of 2025. https://t.co/uIQ7cG4kfQ

A couple weeks ago, 150 VIQRC & V5RC teams competed at the UK National Championship in Telford, England! 🌟 These teams showed the high caliber of robotics excellence in the United Kingdom! @VEXRoboticsUK

We look forward to greeting some of you at #VEXWorlds this May! ✈️🤖

Finally a peek of Mercury. Perfect gap in the hedge 😄

[Alastair Vaan @BitbyBot]

Icarus and Ringo safely through to the semis. And one will advance to the final. The third year running for a Radley team in the finals. Outstanding!

Drivers meeting time. UK Vex Nationals 2025

Three Radley teams, inspected and raring to go.

A huge 12 match qualification session, over two days follows.

Let’s go!

In a lovely moment, Ibex post a 26 skills to place 5th with the skills queue getting shorter and shorter. A great testament to their skill and a super contrast to a difficult qualification session.

Two teams in top 5 national skills. 👌
