    I don't usually make book recommendations, but I think this knowledge should be mandatory. Extremely important health knowledge that has hundreds of studies and many metastudies, huge effect sizes, etc. presented in an accessible manner by

    TIL Google is the reason dates have dissappeared from blogs. I always assumed the authors considered their content timeless . I wonder how it actually affects engagement. I can't waste time reading tech content without a date..

    It took 3 years to get Esc key back. I'm not sure I'll live enough to see the remaining 12 keys. After the 16" disappointment I think it's time to evaluate alternatives and perhaps a Pixelbook with 32GB RAM

    Cloud bold statement "instant infinite scalability". If you've went through the actual pains of cloud scaling you also know the fine print: "Within quotas. Quotas are quite limited. Increasing quotas is not only not instant, but quite painful and sometimes impossible. Good luck"

    I could write a book about “Underdog by default - doing it ‘wrong’ as a way of living”. Since the first grade to 12th without any I, II, III “award” by choosing what to learn to how not to get promoted in a corporation by choosing what is work. There are trade offs.

    Without full details on the program, stage-agnostically (vastly early/founding-stage), what level of equity would you happily part with to experience a new kind of global, online-first startup accelerator for transforming FOSS creators into COSS founders? 5 months. $500K.

    A demonstration of the conservation of angular momentum using a Hoberman sphere. Angular momentum depends on the rotational velocity of an object, and on its rotational inertia. When an object changes its shape, its angular velocity will also change.

    CPUs solve a replicated state machine problem for cache consistency. This is not much different than what Paxos, ZAB, Raft and others try to solve. Latest security issues likely shows that cache consistency is / will be a byzantine fault tolerance problem

    A cluster scheduler and a JIT compilation are not that much different.

    Are more than 1500 microservices needed to realize 1) you're doing a job already done much better by compiler infra 2) you'll eventually need a "distributed linker" and perhaps some type checker, etc. You'll end up reinventing all lessons learned in compilers.

    It’s fascinating how we try to encode a big bag of information consisting of several api surfaces in 2 numbers which we then call “semantic”

    "it works on my machine" can be solved by fixing all other machines. As a bonus you get to say "my other computer is a datacenter" on the same t-shirt.

    What's a good alternative for the now removed OSX dashboard if you want to see weather, calendar, notes etc widgets with one key press?
