  • I think that one of the reasons that I’m not worried about AGI is that I’m still waiting for the end of the world to be caused by Quantum Computing

  • By Default, Signal Doesn’t Recall | Signal Windows app leverages DRM content protection hacks to hide messages from Windows Recall

    2025/05/22 02:49:16 BST

    According to Microsoft’s official developer documentation, setting the correct Digital Rights Management (DRM) flag on the application window will ensure that “content won’t show up in Recall or any other screenshot application.” So that’s exactly what Signal Desktop is now doing on Windows 11 by default. https://signal.org/blog/signal-doesnt-recall/

    The screen-time moral panic is not yet over, and this guy (thread) is being roasted on bluesky for selecting arbitrary experts, asking them if screen use MAY be correlated with harm, and graphing the results as if causative: Via: https://www.newscientist.com/article/2480657-attempt-to-reach-expert-consensus-on-teens-and-phones-ends-in-argument/

  • Mid-Book Audiobook Review: “How Spies Think” by David Omand

    2025/05/18 11:30:36 BST

    Christ, I’m having a hard time with this book, and I’m not even done / he hasn’t even gotten onto the “tech industry” parts yet. I seek greater understanding of the mindset of how Sir David Omand, GCB, former head of GCHQ, got on stage at an event I attended in 2015* and said words

  • I swear the #Eurovision song contest is the single best argument / thought-experiment against Messenger #interoperability under the EU Digital Markets Act

    2025/05/17 19:37:39 BST

    Imagine you have a single messenger app which brings together SMS, WhatsApp, Messenger, Telegram, and one or two other chat apps; what would it really be like to have the same conversation 3-to-5 times over in 3-to-5 different “places” in the same interoperable “app”, but with different “platform” backends? It would be bedlam, because… …because each

    2025/05/14 13:27:43 BST

    …and for my taste has (so far) entirely ignored the positive benefit of Snowden’s impact on online security and safety. We would have: no WhatsApp or Messenger end-to-end encryption, no mainstream (e.g. BBC) “darkweb” sites, no/delayed TLS 1.3, no “Schrems” laws, reduced drive for PQ algorithm adoption, we would probably still be using RSA rather

  • Wikipedia challenging UK law it says exposes it to ‘manipulation and vandalism’ | Wikipedia | The Guardian

    Personally I’m disappointed that Wikipedia is not challenging the whole thing, but this is better than nothing: The foundation said it was not challenging the act as a whole, nor the existence of the requirements themselves, but the rules that decide how a category 1 platform is designated. https://www.theguardian.com/technology/2025/may/08/wikipedia-challenging-uk-law-it-says-exposes-it-to-manipulation-and-vandalism

  • A “Duck Test” for End-to-End Secure Messaging

    2025/05/07 20:17:15 BST

    This is my technical definition of End-to-End Encryption* which can also be summarised as: “there are ends; respect them” …but this version has the advantage of being measurable. I don’t believe I’ve previously posted this as a standalone blog post; the embedded video is my test run for the presentation which I subsequently gave at
