Content warning: Medical stuff / MRI selfie

On the 10th of December 2024 at about 4pm in the afternoon I had a sudden shivering attack. The room wasn't cold, but I was, so I took to bed and shivered on the electric blanket until I napped for a few hours.
Woke up groggy, and never got better. Feeling light headed and occasionally dizzy and half stoned all the time. Can't handle booze or dope at all any more. Doing the job feels like trying to program drunk, concentration shot and short term memory failing.
Various doctors have ordered batteries of tests and put me on drugs to reduce my blood pressure but nothing that's really helped.
They did an MRI last week. Apparently everything looks normal which is good I guess, but still leaves symptoms unexplained.
There are worse fates than feeling half drunk all the time I suppose.
Given no visible brain damage, about the best suggestion anyone has is to stay off booze and drugs (which is easy, since I can't handle them any more) and get back to meditation. If it's damage so small the MRI can't pick it up it'll get better slowly probably. 🤷
Anyway, they gave me the MRI data upon request, so I spent most of yesterday importing it into Blender and making some visualization.
Ladies and gentlemen, I present: My apparently completely normal brain in an MRI selfie.

Yes, yes, yes, yes, @…! 👏
“For now, I’m planning on continuing to roll up my sleeves. I want to make things because I’m human and alive. I want to go on journeys and grow. I’m not always looking for an easy path, I want the friction. Because if I give up the journey, what am I really making? What do I actually learn?”

Content warning: re: Doctor Who - Reality War
:tardis:

Confusing episode. Let me clear it all up.
The world is sinking into the doubt needed to rescue Omega, remember, and The Doctor is falling with a balcony that's separated from the building.
How does he get out of that?
Well, saved by a literal magic door that pops out of nowhere, leading back to the time hotel. 🤨
Anita, who he spent a year with once a couple of Christmases ago, has been popping around the Doctor's entire long life, peeping on him with the Daleks and stuff. Trying to find him on the Earth's last day. Today.
And now he's rescued, today turns into a groundhog day. Same day over and over again. 😆
There's another woman that's been stalking him through time lately, Mrs Flood. She was following him everywhere, but she had Xmas off she reckons, so didn't see the Time Hotel bit. Thus the element of surprise in the deus ex machina rescue. 😀
The Doctor is broken free of the wish spell now anyway, popped his conditioning, and can use the time hotel's door to recall Unit and break them all out of the wish too.
The Rani pops in to say hi and explain her plans. 😝
How did the Rani survive the end of the Timelords? She flipped her DNA to sidestep the genetic bomb apparently? Well that makes no sense, but nor does anything else so no time to ponder.
The end of the Time Lords made them all Barons... No, made them barren. There can be no more children of the time-lords.
She's popping Omega back out of the underworld for his DNA because the timelords are all barren and she wants to recreate Galifrey.
But wait a minute: Poppy is the Doctor's kid in wish world! So she should have Timelord DNA too! Maybe that could work?
No. The Rani is a nazi, don't like the kid's contaminated blood. She's got human all over her DNA. Eww.
Rani pops off back to her Bone Palace, and makes the bone beasts attack.
The Doctor explains that the Giant dinosaur skeletons are beasts that pop in to clean up the world when there's a reality flux, and the Rani has turned them on Unit HQ.
So the UNIT HQ turns into some kinda ship? Like the Crimson Permanent Insurance. Lol. It's blasting lasers at the bone beasts and turning around, and has a steering wheel like pirate ship now. 🤣
During the battle, the Doctor pops out to take a ride on the sky-bike, looking like something from Flash Gordon, and crashes into the Bone Palace.
Too late though! Omega is pretty much here now. He's a giant boney CGI zombie, become his own legend. Looks great but doesn't really seem like Omega, who ought to be held together by pure will.
Omega eats the Rani! One of the Ranis anyway. Mrs Flood avoids being eaten. She pops off with the time bracelet. "So much for the Two Rani's. It's a goodnight from me!" as she disappears off into time. Great gag. 😁
The Doctor just shoots Omega to get him back into his box. Pops a rifle off the wall. The Vindicator has apparently also got a built in laser as well as locator beacons. So that's handy. The Doctor doesn't use guns but some of his devices work like one. 🔫
So all is well! The day is saved and the wish is over and baby Poppy survives in a time box! 🍻
They're going to take the space baby off to do space adventures. Ruby is jealous of seeing The Doctor and Belinda vibing like that, as they plan a life in space with the space baby. Aww. Poor Ruby. 😭
But then Poppy pops off! Disappears entirely, and everyone other than Ruby forgets. Ruby remembers because she's disappeared from time herself in the past they say.
Okay: to save his child and on Ruby's word alone, the Doctor will sacrifice himself to turn reality one degree.
He goes off to commit suicide by Regeneration, but Thirteen is here! She's popped out of her timeline to stop him! Or maybe to help, with a motivational chat instead. Gives him a pep talk then pops back off again.
The Doctor zaps reality with his Tardis, dying but holding off on the actual regeneration for a few moments to go check on the kid.
The kid is safe! But isn't his own kid any more. Poppy has popped all her Timelord DNA and is just all human now. Poppy's pop isn't the doc, it's someone called Richie.
And Belinda has been so keen to get home all this time in order to get back to her Baby! Who isn't a timelord, and definitely didn't exist until she was wished into being.
This may not be the most ethical action The Doctor has ever taken: To bend the whole universe in order to recreate a baby that was accidentally wished into being out of nothing. Twisting time to give a child to a nurse who didn't previously have a child, or even remember the wish. Then it's not even the same child that disappeared, coz this one is all human. 🤷
But the doc is popping off to regenerate with Joy in the stars, and... Turns blonde: "oh. Hello?" 🤯
It's Rose! Billie Piper is back? Fantastic!
Is Rose doing a David Tennant Impression there?
Billie playing the Doctor, doing a Tennant impression as Bad Wolf? Amazing. Can't wait.

Here's a more positive challenge for the "AI scientists": reproduce a paper. From the PDF alone, implement and re-run the experiments as written, filling in the gaps as necessary and get the same results.
That's a lot more meaningful than passing peer review and it would actually be quite useful to automate. It could become a required check on any accepted paper.

Construct the Dice

By Hans-Karl Eder

Marie has one regular die labeled with the numbers 1, 2, 3, 4, 5 and 6 and a second cube that is completely blank. She labels this cube in a special way. If you roll both dice, you can get the following totals: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12. The special part: all 12 total vaslues are equally likely to be rolled. How did Marie label the cube?

For Trump,
“it’s no billionaire left behind
— and good luck to everyone else.”
“It’s telling that President Trump has chosen to release his budget on a Friday night with no fanfare whatsoever,”
said Sen. Patty Murray (D-Wash.), ranking member of the Senate Budget Committee,
following the administration’s release of approximately 1,200 pages of budget documents.
“That’s probably because his budget would raise costs for working people,
