    I like breakfast so much that sometimes, when I go to bed, I'm lying there super excited to wake up next morning. Already imagining the taste and smell of bread and coffee.

    “Ripping an orca from its ocean world, [...] putting it in the sterile geometry of a claustrophobic swimming pool [...], and then trying to decode its whinnies and clicks as a simple matter of signal processing strikes me not only as insanely cruel but also insanely futile.”

    A former Tesla employee, who worked on their IT infrastructure, is posting in a subforum of a subforum, a little-known place for funy computer forgotten by time. His NDA has expired. He has such sights to show us. Join me and I will be your silent guide into a world of horror.

    For the last year, I’ve been reporting out what it felt like to be inside a company hit by NotPetya, the unprecedented $10 billion cyberattack. The result is this WIRED cover story: how Russian malware took down Maersk, the world’s largest shipping firm.

    "[...] some applications where confidentiality isn’t important, for example some motion control that might involve very simple move instructions [...]"

    I spoke to about my fears around the privacy & security of the next generation of sex tech, and why I believe we need the protocols facilitating remote sex to be metadata resistant.

    My in-laws live in Altena, I passionately hate Facebook, and I have zero doubts it radicalizes people (I do call bullshit on the “common internet outage” relation in that story, though)

    The inglorious parts of cryptographic engineering: copying/pasting constants and test vectors into/from SageMath/RFCs, then hammering on the keyboard for minutes to format them as C byte arrays.

    Recently found myself looking for resources to brush up on bitsliced implementations of crypto algorithms. Didn't find much, so I wrote a small introduction for the benefit of future me (and you). Part 1/?

    Thread. I was recently privy to a conversation in which some really smart people in security shared their favorite papers or articles. Security engineering, like other disciplines, has a rich history worth learning from. I'm going to list some of these papers in this thread.

    There’s a raging twitter fire about whether software engineers are actually terrible at what they do. Thread here makes a lot of subtle adjustments to the framing. Worth reading.

    This is wildly disingenuous, I speak as a flight instructor and major IT incident investigator. Modern software authors have the professional discipline of a cute puppy in comparison to aviation practitioners.
