  • Professionals have large networks of neurons. They are sturdy and efficient from repeated use. Memory palaces help to start the construction of these large networks of neurons. Afterwards, as another commenter noted, the knowledge is deeply processed. Mnemonics are replaced by networks of meaning. It is no longer “This algorithm rhymes with tomato”, but “This algorithm is faster if the data is stored in faster hardware, but our equipment is old so we better use this other algorithm for now”.

    Broadly, the progression of learning is: superficial learning, deep learning, and transfer. Check out Visible Learning: The Sequel by John Hattie for more on this.

    Edit: To directly answer your question, experts have so many sturdy neural hooks on which to hang new knowledge that mnemonics become less and less necessary. Mnemonics may be particularly helpful when first learning something challenging, but are less necessary as people learn.

    You could also check out a paradox called the expert paradox. We used to think memory is boxes that get filled. This idea was directly challenged by Craik and Lockhart’s Levels of Processing. Levels of processing supports the idea that “the more you know, the faster you learn”. Note that this is domain-specific. In other words, an expert in dog training won’t learn quantum mechanics faster than anyone else.










  • I do see how the narrative in the headline could be a call to action, but the article doesn’t propose a solution behind which the audience can rally. At most, the article describes how Americans can interpret the inevitable defeat. Of course, this text doesn’t exist in isolation; other texts would have to do the heavy lifting so that Americans rally behind a war effort.





  • I agree that we shouldn’t jump immediately to AI-enhancing it all. However, this survey is riddled with problems, from selection bias to external validity. Heck, even internal validity is a problem here! How does the survey account for social desirability bias, sunk cost fallacy, and anchoring bias? I’m so sorry if this sounds brutal or unfair, but I just hope to see less validity threats. I think I’d be less frustrated if the title could be something like “TechPowerUp survey shows 84% of 22,000 respondents don’t want AI-enhanced hardware”.



  • Agile is indeed more of a mindset than a rigid system. In my recent experience helping a tabletop game team, we applied Agile principles to great effect. Rather than trying to perfect every aspect of the game at once, we focused on rapidly iterating the core mechanics based on player feedback. This allowed us to validate the fundamental concept quickly before investing time in peripheral elements like the looks of the game.

    This approach embodies the Agile value of ‘working product over comprehensive documentation’ - or in our case, ‘playable game over polished components’. By prioritizing what matters most to players right now, we’re able to learn and adapt much more efficiently.

    Agile thinking helps us stay flexible and responsive, whether we’re developing software or board games. It’s about delivering value incrementally and being ready to pivot based on real-world feedback.


  • I appreciate your candor about not wanting to speak on topics outside your expertise. That’s commendable. I wonder if we can still talk with the understanding that we may not know it all. I truly believe curiosity is able to sidestep many of the problems related with ignorance.

    You’re right to be cautious about appeals to authority. My intention wasn’t to suggest NASA’s use of Agile validates it universally, but rather to counter the OP comic’s implication that Agile is inherently incapable of achieving significant goals like space exploration.

    Regarding Agile-like practices in earlier NASA projects, you’re correct that concrete evidence is limited. However, we can analyze their approaches through the lens of Agile principles. Scrum, for instance, aims to foster characteristics found in high-performing teams: clear goals, information saturation, rapid feedback loops, adaptability to changing requirements, and effective collaboration. These elements aren’t exclusive to Scrum or even to modern Agile methodologies. The key is recognizing that effective project management often naturally gravitates towards these principles, whether formally adopting Agile or not.

    It’s an interesting area for further research: have complex engineering projects historically incorporated elements we now associate with Agile? If so, how?

    Your skepticism is valuable in pushing for a more nuanced understanding of project management across different domains.


  • You’ve got a good point. I wonder if this an example of a trade-off between convenience and security. If you’re logging in and you get an MFA prompt, a Yubikey has to be physically searched, while Bitwarden or Proton Pass only have to be clicked. A Yubikey can only hold a limited amount of accounts, while Bitwarden or Proton Pass could hold many more. Of course, a Yubikey could be used as MFA for Bitwarden or Proton Pass, but that would create a single point of failure and reduce factor separation (which I think is your original point).

    While I posted a Bitwarden or Proton Pass recommendation of sorts, I genuinely wonder if it’s advisable to not use MFA at all if the factors will not be separated. Or, perhaps, the best security solution is the one you’ll actually use. I guess the answer is the good ol’ “What’s your security model?”
