  I'm now several hours into rebuilding my raspberry pi cupboard server because something went wrong after updating from bookworm to whatever the new version is. All I wanted was a slightly newer version of PHP 😭

  Hello, I'm from the campaign to launch the word "learnings" directly into the sun. Do you have time for a quick chat about what we're trying to achieve?

  I feel this would appeal to @standupmaths: ISBN-10 numbers with the same check digit upon conversion to ISBN-13. https://oeis.org/A393653 #OEIS

  yeesss, the power!!! We got our electric car yesterday, so it's plugged into a normal 3-pin plug now to charge up. This is my power supply chart: 3kW is going to the car and the washing machine, 1kW to the grid, and 3.3 charging the house battery. I'd noticed that the solar panels had capped out at around 6.2 kW before we got the car, and I wondered if the limit was in how much we can export to the grid or in the wiring from the panels. Looks like the limit was just grom the g...

  Exciting scenes at the maker space: found smoke billowing out of the laser cutter, and nobody else around. Seems the extractor fan gave up. Now surrounded by technicians with hoovers.

  I can buy 15 90cm bamboo canes for £4, or 10 180cm canes for £5.50. Relevant information: I own something that can cut bamboo canes. What to do?!?! 🤔

  I just saw a Lumo train with a progress pride flag on the side, but the triangle bit on the left had a black circle on it. What does that mean?

  Early career researchers: have you been bullied into doing bad science? Pressured to publish only in "prestigious", non-open journals? There's a letter to sign. http://bulliedintobadscience.org/

  Just spent half an hour with my summer student getting into the subtleties of the conditions required for "throwing two dice" to have 36 possible outcomes. I came up with a good example: I'm colourblind, so if we throw a red and a green die at the same time, the student can distinguish them, but I can't. So the outcomes are a property of the observer, not the trial itself.

  Inspired by Alison Kiddle, I've made an Auto-Santa 3000: given a list of naughty things, add up the scores of the things you did. Then it uses the total to tell you the things you did! https://mathstodon.xyz/media/wabXGCyuSpERkVXHjGA https://mathstodon.xyz/media/BiBHC_ZU9XjOmyBGT3I

  At @TMiP some people from Durham presented their project "Young Minds, Big Maths". It's a collection of resources to help talk about maths in early years settings. https://youngmindsbigmaths.co.uk/ What a nice project!

  I've come up with another sequence that I can't believe isn't in the #OEIS (#ICBINIOEIS)! 1, 3, 7, 11, 16, 25, ... Can you guess the next term? Can you guess the general rule? I haven't done one of these for a while, but the usual rules apply: * You can ask for hints. Say if you want a big, medium or small hint. * Put any guesses under a content warning. * If nobody correctly guesses it, I'll post the answer in a week or so.

  I've woken up to dozens of emails saying someone's bought my "keep calm and multiply" matrix t-shirt - https://www.redbubble.com/shop/ap/37572142 What's that about? Has someone mentioned it in a video?

  On 12th June I'm presenting at an LMS Good Practice Scheme Workshop: Supporting Staff and Students with Disabilities. It's in-person and on Zoom. There's information and a registration link at https://www.lms.ac.uk/events/supporting-students-and-staff-with-disabilities Excitingly, it's happening at De Morgan House, which has no step-free access. I suppose the LMS, in its majestic equality, will allow you to watch the Zoom call from the street.

  What's the line between Google saying in 1998 "we could try throwing lots of commodity hardware at this big problem", and AI companies now buying up the entire computer supply chain? Like, are the AI companies a sudden jump in ambition, or has it been increasing gradually? Were there any big supply chain crunches like this earlier in computing history?

  listening in to a hybrid meeting over Teams. The sound quality isn't great. I thought I heard someone recommend a book called "queer data and rainbow trout". Turns out it's "Rainbow Trap"! 😆 https://kevinguyan.com/rainbow-trap/

  The accessibility checklist for academic conferences and events that I had a hand in producing now has its own proper address, not under my staff webspace: https://accessible-events.ncl.ac.uk/ If you work at a university and you're planning any sort of gathering of people, please have a look at it. It contains practical advice about how to make sure people of all sorts are included and able to take part in your event. #accessibility

  I'm preparing a talk on accessibility of e-assessment, so I'm dredging my brain for memories of inaccessible questions I've seen. If you have any suggestions, please tell me about them!
