  • Pretty sure that knowing COBOL isn’t the hard part. It has relatively few language concepts.

    This lack of language concepts just makes it difficult to reason about it, so that’s what you’re getting a paycheck for. Well, and possibly also because it might take months to have a new dev figure out your legacy codebase, so it’s cheaper to keep the current dev by paying them competitive prices.


  • Oh man, a few years ago, we had a military dude as conductor in our wind band. And I was always one of his favorites, I’m guessing because I have broad shoulders and a deep voice – prime military recruit material.

    …except that I’m vegan. So, one day he sits next to me during lunch and asks me why I’m vegan. I do the usual dance of avoiding the topic, but he does not want to let it go. So, I tell him that I think killing animals is wrong. He walked out of that conversation like a hurt gazelle.

    Like, fuck me, dude, if you’re gonna do the whole military tough guy spiel, but cannot take a kid disagreeing with you, then maybe you’re not as tough after all.


  • That argument annoys me so much. Each vegetable does cover all amino acids, they just don’t have them in the exact relations that our body needs. But if a vegetable has only 50% of one amino acid compared to the distribution that our body needs, then you can abso-fucking-lutely just eat double of that vegetable. Or as you say mix-and-match.

    A typical Western diet includes far more protein than the body needs for maintaining itself either way.


  • Ah yeah, there’s various technologies that I don’t mention too loudly. For example, all things considered, I’m probably an above-average Python dev, but I never enjoyed writing it, so when I get asked about it, I always answer that I’m not too confident with it.

    Which, in my defense, isn’t even really a lie. My specialty is large-scale projects, which is something where Python with its loose typing just does not give you confidence…



  • Yeah, I agree that there could probably be a way to “close” Activities, which doesn’t do the session management, so explicitly just throws the windows onto another Activity (or maybe prompts you when there’s still windows on that Activity), without having to outright delete that Activity.

    Deleting an Activity is relatively disruptive, since you may have files linked to it or nicely setup wallpapers and such. And there are a number of places where Activities show up, where it can be annoying to have Activities showing up that you’re not currently using.

    I can imagine them being open to that suggestion, if you articulate it well.
    From what I saw, they did make a lot of changes to remove the start/stop functionality, but most of it was session handling code. So, it might not be too additional much trouble to add a way to close Activities instead.

    As a wise Nate Graham once said: The most reliable way to find out whether people use a feature (and how they use it) is to remove it. The second-most reliable way is to announce its removal.
    Well, you did miss the announcement, so it probably felt a bit rude to you, but yeah, you should still consider this the start of a conversation. They’re not hellbent on removing this feature.



  • The thing I never understood about PowerShell is that it’s partially more verbose than C#, which is one of the most verbose programming languages in existence. It just feels like you might as well go for a full-fledged programming language at that point.

    The appeal of Bash et al is that the scripting is almost the same as the interactive usage, which you already know. But because PowerShell is so verbose, I’m really not sure people do use it interactively.

    I guess, that code snippet in the article makes somewhat of a difference, in that PowerShell offers better features for interop between processes. But man, that still feels like it could’ve been a library instead…

    I’m no expert. I probably know too little about the propagation speed of a wave to understand what you mean there.

    But here is a scenario where something is faster than light in the given medium: https://en.wikipedia.org/wiki/Cherenkov_radiation

    As I understand, neutrons and gravitational waves are also bound by the speed of causality, because they have no mass. And I believe, unlike light, they are unaffected by electromagnetic forces that a material exerts, so they would presumably (always?) travel faster than light in that medium.

    I will also say, that from what little I understand of this video: https://www.pbs.org/video/pbs-space-time-speed-light-not-about-light/
    …it sounds like trying to determine the speed of causality by measuring it, is kind of backwards. You’re at best experimentally confirming what has to be a given under our laws of physics.




  • That’s kind of why I never feel great about buying video games. The price is pretty much entirely arbitrary.
    Like yeah, they did an investment, it is fair that they recuperate that. But the actual price they need to ask of each customer entirely depends on how many customers there are.

    And so, they will always start out asking more than what they expect to need to ask of each customer, which just feels like I’m paying too much.
    But even when they do put it on sale, there’s likely going to be sales in the future where they sell it for even less. It’s not like they need to empty out a warehouse or such, where they put up uniquely low prices. So, even when I could get a game on a sale, I’ll feel like I could also just wait longer…



  • She did the math (with some assumptions), but basically 0.25 mL of lemon juice will turn 500 mL of alkaline water into neutral water:

    This is in the video at 13:16.

    The reason is that pH is a logarithmic scale. Alkaline water has a pH of about 8, which means it has a tenth of the hydrogen ions compared to neutral water at pH 7.
    Lemon juice has a pH value of 2, which is 1,000,000 times more hydrogen ions than there are in pH 8. So, you just need a little bit of lemon juice to increase the hydrogen ions in alkaline water tenfold, which makes it neutral.
