Looking back at the United States (photo I took in Philadelphia in 2012, from a Wendys carpark) while they prepare to scuttle her. Live stream is here: https://t.co/D50RpXMTc8

Patrick Stewart in the final scene on Star Trek: The Next Generation.

It’s extremely simple, but reveals so much of his character if you watched. Somehow his sense of duty and sensitivity, along with the admiration of his crew shines through.

RIP Captain.

[All The Right Movies @ATRightMovies]

One of PATRICK STEWART's greatest roles was Jean-Luc Picard in Star Trek: The Next Generation - a Captain who stood up for what was right.

He delivered many great speeches in the role. This, from The Measure of a Man, is one of the best.

Very sorry to see that Walter Koenig has passed away. Let's remember him with a look at Chekov's finest moment. https://t.co/qRqMCuHSTF

The replies to this post are the best thing I’ve seen on the internet this year. No exaggeration.

Bryony and Matt are spending £820,000 on a modern, high-performance home on the Cornish coast - designed to meet the highest environmental standards.

Will they pull it off?

Desde Frías, Burgos, agradecidos con que nos encendieran el castillo para este momento único.

My small British company was bought by Americans. I have just been formally reprimanded for sarcasm and sardonic commentary. I told the disciplinary panel I was grateful for the opportunity to reflect on my attitude going forward and would be certain to bear it in mind in future.

SUCCESS! Total Solar Eclipse 2026 from just outside the rural town of Duraton, Spain.

Four years of planning the shots paid off.

Returning to a document I started writing this morning. Never finish on "we will consider". Who only knows how that sentence would have ended...

Lovely weather for @Shieldhall arriving at Falmouth this afternoon.

Impressively in numerous announcements to stop people boarding the wrong train nobody has apologised for the inconvenience. Incredible customer service.

Sheer incompetence from @GWRHelp. The 1625 Exeter St David’s - Plymouth is delayed by 22 mins. Platform staff said stay on platform for Teignmouth and not to get 1631 stopper, 1625 will get there first. 1625 now running to Plym direct, 7 mins after stopper left…

New paper with @zihao_chen_ out on the arXiv from @exetercompsci : a scalable framework for measuring how public transport actually performs — not just how it's supposed to using large scale data from @busopendata

I’m in this boat. I must be tripping AI detectors all over the place…

@GregKamradt I use em-dashes and colons all the time, sigh. AI is stealing our best punctuation marks. Who can we sue?

Just attempted to appear knowledgable by quoting Einstein. Sadly it's been (immediately) pointed out that I'm actually quoting Douglas Adams...
