    LLMs hallucinate constantly and cannot be trusted to produce code without human verification.

    LLMsdesign

    Their wordsLLMs constantly hallucinate and cannot be trusted. I still have to verify and iterate a lot but now I usually focus on architecture and design instead of code style.

    As an LLM's context grows, it pays less attention to instructions placed in the middle than to those at the start or end.

    LLMs

    Their wordsAs the context grows, a model starts paying less attention to instructions in the middle of the context in favor of what is at the beginning and the end.

    Failures are more often explained by time pressure than by stupidity or malice.

    Their wordsNever attribute to malice what you can attribute to stupidity. And never attribute to stupidity what you can attribute to time pressure.

    Thunderbolt's official wake-from-sleep certification does not guarantee the feature works reliably in practice.

    Their wordsAt this point, I had pretty much given up and filed Thunderbolt's "wake from sleep" promise in the "unreliable" folder, right next to Bluetooth Pairing.

    Programmers who refuse to use LLMs to code will fall behind those who do.

    LLMs

    Their wordsWriting every line by hand is no longer the norm. Those who refuse to use an LLM will fall behind because they won't be able to produce as much

    Code quality still matters even as LLMs make writing code much faster.

    Their wordsBut for everything else, code quality still matters tremendously.

    Smaller teams are better

    team size

    Their wordsWe can accomplish more with smaller teams. We may not be far from the '90s model, when a team of four could produce professional software.

    Multimedia design succeeds by building up from a platform's real hardware constraints rather than compressing full video down to fit them

    design

    Their wordsMost FMV games looked bad because developers followed a top-down approach trying to cram a real movie into a tiny CD-ROM using a weak CPU.
