  • Someone shared this on Mastodon so I’ll just repost my thoughts from there. (Bonus for Lemmy, I was forced to squeeze all my thoughts into 500 characters, so this is the most succinct I’ve been on this site!)


    Pretty incredible how little people seem to understand these. For one thing, every method other than waterfall is a subtype of agile methodology. The major distinction is that waterfall has a series of phases from design through building, testing, and delivery that attempts to plan the whole project up front. Agile methods focus on smaller iteration cycles with frequent, partial deliverables.

    Something like kanban is designed for continuous delivery: we want to go to mars weekly.

    LEAN development is a scam though, that one is accurate.

    There are a ton of competing models for how the early universe formed. In order to explain why the universe is so smooth and flat though, they all invoke the idea of a short (10e-37 seconds) period of time immediately following “the singularity” that is presumed to have been literally the first point. During inflation the universe blows up 100000 times in size (and correspondingly drops in temperature by the same factor) then immediately slows down to roughly the rate of expansion we see today.

    There are a lot of simulations and theories about this could have worked. And I’m sure they all have lots of grounding and math and believers. But none of thr explanations I’ve ever heard amount to more than “when I do this funny thing, the math works and none of of us know why” and that has been the state of quantum physics for 70 years: a series of “we don’t know but the math works.”

    In software, we call that tech debt and I feel like our current model of profit-driven science isn’t capable of actually finding or reporting the answers that underly the debt-riddled results out of modern labs.

    The hot big bang is basically just “let there be light” wrapped up in science words and don’t get me started on the period of rapid inflation. It’s incredible to me that the bedrock of modern physics is hand-waved away to get grad students focused back on either bigger nuclear plants and bombs or more qubits.

    What? You use these words, but I do not think they mean what you think they mean.

    Quantization is probably the result of vibrational modes, that doesn’t mean irrational numbers don’t exist, just that we can’t measure an infinitely precise value. Tau and root-two exist, they arise naturally in the most basic geometric shapes.




  • Out past the planets is the heliopause, the final boundary between the solar system and interstellar space. Voyager discovered it, but other probes have confirmed it. The radiation and particles emitted by the sun create a pressurized bubble around it, where plasma (energized particles, mostly hydrogen) is much denser than past the heliopause. Cosmic rays are more prevalent outside it.

    I’ve heard it compared to the empty zone around where a sink faucet first hits, creating a little “wall” of water around it as the splashing water pushes back the standing water.

    “Empty” space is anything but. There’s tons of particles and energy flying though it, just not as dense.




  • You seem like a person who wants to try and do well and be a good manager. So be very careful of burnout, because the constant tension between doing what is right for your team and meeting upper-management expectations can drive you crazy. It did me anyway, which is why I don’t manage anymore.

    Take regular vacations and actually disconnect from work when you do. Try to do the same for at least 1 or 2 weekends per month. Being organized is important and helps with the job and the burnout, but there’s a thin line between “keeping notes in Obsidian keeps me focused” and “my entire 2nd job is now maintaining Jira tickets.”

    Organization is for you, keep it for you, and don’t let your organizing become a part of your “public api” or else it’ll become another avenue for status updates that you’re obliged to maintain. Turning your notes and private charts into data for upper management is why you compile special reports, just for them.



  • I made a static site with Hexo a few years back. I thankfully didn’t make any “Get started with Hexo” posts but I did only really use it for a few months. I think that puts me in the cluster with the “switch from Jekyll to Hugo” people. Now it just sits there, absorbing some money every two years for the “personal website tax”.

    Shame too, I constantly think I need to get back to it. Hexo is nice, popular with Chinese users I think. I don’t recall now why I liked it over Jekyll or Hugo, but I’ve always loved an underdog. Once I got the hang of using it, it was very customizable and fun to work with.
