Question from today's Departmental Board Games Afternoon: is it possible to win a four-player round of Red Seven after playing just one card. Turns out (I think): Yes!
Starting game state plus top player's unbeatable opening in Red Seven.

Got my voting done, comrades. If there's one thing the last half decade has proven, it's that UCEA won't listen unless we *make* them listen. Chalk one more up, @ducu.bsky.social
Ric posts his ballot, and looks damn good doing it.

Representing @ducu.bsky.social at a Durham Pride fundraiser at the miners' hall tonight. Disgusted, though not in any way surprised ,at our new council's decision to torpedo funding.
The projection at the miners' hall. We're gonna watch a film!

Solidarity with the BMA today, accused of undermining the labour movement by a chief architect of the undermining of the Labour *Party*, Wes Streeting.

Wes, mate. This was the vote share in your constituency last year. You do NOT get to argue only absolute majority votes have legitimacy.
A pie chart showing the vote share in Wes Streeting's constituency in 2024, showing he obtained barely one third of the votes cast.

I took a screenshot of the other example that really annoyed me. Apparently having a male child in a single-sex space for women doesn’t invalidate the nature of that space, because a child is unlikely to pose a threat 16/22
13.4.3 A council swimming pool has separate men's and women's changing rooms. One of the aims of having separate-sex changing rooms is to safeguard women's ability to access the facilities and use them safely. A woman is allowed to take her male child under the age of ten into the women's changing room. This does not undermine the aim, because it is unlikely that young boys pose a threat to women's safety. It also contributes towards achieving the aim, because fewer women would be able to use the swimming pool if they could not bring their children with them.

Prophets grant me the brass neck of a university who will fly the Progress Pride flag while simultaneously refusing to tell trans staff and students which bathrooms they're safe to use.

Happy birthday, Eva! Please enjoy Quiz in a perfectly normal sleeping pose, one any mammal would find comfortable and reasonable.

Was delighted to be able to stop in Brum today and join a trans rights rally. Full solidarity with my trans brothers, sisters, and siblings.

Copies of my new (and first!) book, Infinite Diversity, Finite Combinations Vol 1.1.

(Seriously, just look how nice Hye's design is!)
Interior page for the book. The essay number is grey in a white box, inside a black box including the essay title and first line. A variant of the book's IDIC triangle points downward to the text, with a simplified IDIC also acting as a flag for each subheading. It's AMAZING.

Delighted to announce that, after an outrageous amount of flapping (because I had/have/will always have no idea what I'm doing), the first Infinite Diversity, Finite Combinations book is up for sale, in electronic form! It's SO pretty, too! Go get your Kirk on!

www.idfc.co.uk/category/all...
Front cover of the book, reading "Infinite Diversity, Finite Combinations. Volume 1.1. Written by Ric Crossman". The cover shows a green shirt with gold trim, along with a comet and a spatial anomaly. Back cover of the book, reading: "Trek back to where it all began! Few TV shows can claim the success of Star Trek. Over six decades and counting, and a dozen shows and counting, Trek’s delight in the diversity of an infinite cosmos is unmatched in its firing of the imagination. So why do we always take the same old route through? Based on the website Infinite Diversity, Finite Combinations, this book starts you down an alternative path. A new combination for the infinite diversity. A season-by-season comparison of every Trek show, gleefully flaunting the Temporal Prime Directive as it travels through time to find the links between Trek eras, and their surrounding cultural context. In this book, you’ll find thirty essays on TOS‘s first year, each revised and expanded from their online versions. You’ll also find five brand new essays covering “The Cage”, The Motion Picture, the first Trek printed fiction, Trek antecedents Voyage To The Bottom Of The Sea and Lost in Space, and a consideration of the nature of truth in fiction, according to laws both social and mathematical. You’ll also discover answers to questions you might never have thought to ask. Could Spock be suffering from chronic depression? Which beloved fan-favourite episode has most damaged the franchise? What might Trek have looked like had a tragic traffic accident ended Harlan Ellison’s life before he had the chance to change history? So why are you still in stardock? You’ve a whole galaxy to explore. Best warm up the nacelles, and head out to the final frontier." The back cover also features a design loosely based on the Trek IDIC.

Deploying my ballot for the UCU elections. Engage democracy, people!

@ducu.bsky.social
Ric prepares to post his ballot. He looks awful, but at least he's *almost* got the envelope into the postbox.

Playing around with something different for next month's post, as a precursor to something @blindmath.bsky.social and I are cooking up.
A blue sphere of radius 26 light years, with Romulus in the centre. A circle around the sphere near the bottom pole is shown with radius 7 light years. This circle is shown to be on the same vertical pole as Sol.

Been doing some moonlighting as a TV critic again.

(Cover art by @harrysaxon.bsky.social, who is all-around groovy and a man you should hire to art for you.)
A book cover, featuring Kirk's green command shirt, the comet from Balance of Terror, and Murasaki 312 from The Galileo Seven. The cover reads INFINITE DIVERSITY, FINITE COMBINATIONS 1.1, by Ric Crossman.
