    I have a cryptic crossword clue and answer ... I can&#39;t see entirely how to construct the answer from the clue, and given that it&#39;s from fiction, maybe it&#39;s not kosher. If anyone would like to DM me I can pass on the clue, provide the answer on request, and you can help me understand what&#39;s going on. TIA. Edit for extra information: This is allegedly from a crossword in the 1930s. (Feel free to boost for reach) #CrypticCrosswordPuzzles #Cryptic

    Time for a question. * In the expression &quot;18÷3x2&quot; ... if I say (regardless of anything you&#39;ve ever been taught) to do the multiplication first, what happens? I&#39;d run this as a poll but I don&#39;t want to lead the witnesses, so to speak. * Start with &quot;18÷3x2&quot; * Do the multiplication first * What are the steps you go through? If you are content to do so, please boost to get out of my bubble. Thanks. CC: @solderandchaos@mastodon.me.uk

    HAH !!! My (first) talk from #EMFCamp is up! https://media.ccc.de/v/emf2026-60-1-juggling-surprisingly-mathematical I honestly didn&#39;t know what I was going to say, although I&#39;ve been giving talks about this material for a long time, so parts of it were well rehearsed. I&#39;d welcome feedback. It wasn&#39;t perfect, but let me know what you think. I only ask that you be kind. Honest, but kind.

    This graph should be front page news. Instead, there is silence. This is now a projection, not a prediction, not the result of a model. These are measurements, it is what is happening. Now. https://www.lyrebirddreaming.com/post/the-graph-that-should-be-front-page-news

    Spotted on a Health and Safety poster, and again my mathematical mind betrays me. Quoting: &quot;Safe use of projectors : Avoid staring directly into the projector beam at all times.&quot; I avoid spending all my time staring into the projector. I stare at it occasionally, here and there, now and again, but I don&#39;t stare into it &quot;at all times&quot;. So ... is that OK? 1/n

    One thing no one ever talks about being an adult is how much time you debate yourself on keeping a cardboard box because it&#39;s, like, a really good box.

    EDIT: FOUND !!! I&#39;ll avoid spoilers for those who enjoy the chase, I&#39;ll happily reply to DMs asking for the answer ------------------ Here&#39;s a real challenge for die hard fans of older #SciFi ... I remember in my teens in Australia, 70s?, reading a story or novel in which two computers (or neural nets) were interacting, having a conversation in English, and at one point one of them offered the other a banana. The humans who were watching discussed this, and one said that this wa...

    Fabulous pass of the #ISS ... totally clear skies, magnitude around -3.6 ... brilliant to watch it sail serenely overhead. Wanted to share the experience with a passerby: Me: In about 30 seconds the International Space Station will come into view over there. Him: Will it. I suppose you also believe we&amp;#39;ve landed on the Moon. Me: Yes. Him: What about the Van Allen Belt Me: They went through thin parts, and they&amp;#39;re a lot less serious than people seem to think ... about the sa...
