There’s often a skill that seem interesting, but I can’t see doing anything for me in my day-to-day life. What have you learned that was a lot more effort than the payoff was worth?

    As an old time computer nerd I have uncountable examples of deprecated knowledge. There is no use in knowing how to use the reserved upper memory in autoexec.bat and config.sys, nor how to use Napster or Kazaa.

    But all these skills do shape your brain and way of thinking.

    Assembly language taught me to be precise and think before typing. Flash taught me that nothing lasts forever, as big as it might seem.

    Eventually, all this adds up and creates a profile that is very demanded in my career.

    That said, my mom taught me to thread a needle without looking. And I can’t sew, so that’s that.

      Man, 99.9% of those old commands are still 100% valid. Knowing about memory addressing is super useful when you need to help the computer remember that it does what it’s told, even if it doesn’t think you should be allowed to at first.

      While knowledge like that is deprecated, the foundational skills and problem-solving it gave you are still very valuable. Modern systems are still built upon old roads, so people with this base level of knowledge have a far easier time sorting out what fixes are needed. Like being an old mechanic that diagnoses a car issue almost immediately because they can hear the issue without hooking up a digital diagnostic, they already know what to look for.

      I miss older computers, lol. 2000-2010-ish was the golden era.

      I had to learn himem.sys and loadhigh when I was about 10 years old and the family PC HDD crashed. I had a copy of DOS and a manual the size of a phone book. The only way out was to write my own boot disk.

      But yes, these days it’s a bit of a useless skill.

        Depends on the cert and the environment you are already in.

        For example, I’m an IT Consultant, we kind of rely on ‘professional certs’ to get work at client projects, especially if a project is covering specific niches and we have consultants that have certifications within those niches.

        Also, many of the more mainline certs can definitely be worth getting (especially in the early career stages), as a quick example some of the CompTIA certs like Networking+ (a colleague got his job with us solely with that cert btw)

          That’s probably the worst part of it. In some places they’re required or very helpful to have, even though they’re still complete bs and a scam. Cisco is the perfect example. Their certs are useless and constantly changing, they’re really expensive, and they don’t really teach you about the general subject (networking). They just shill their products and their proprietary, non compatible way of doing stuff, and you pay thousands for that. Yet jobs still want those certs, even if they don’t work with Cisco.

            I remember looking into getting Azure and GCP certs some years ago and went through a few prep courses. It turns out getting the initial certs for cloud services like them is basically to be a salesman for them. It’s like they’re training IT people inside companies to be embedded salespeople for them. Insidious, and kinda genius.

    I’m a trained electrician. Despite taking and passing a reputable school for it, I can’t get licensed to do it in my state because you have to have 2 years apprenticeship. You get an apprenticeship you have to go through a school supported by the union. The only school supported is the one they own.

    Despite being fully capable of wiring a building to code, installing a solar array or electric car chargers I can’t do shit with the information and it way a year and $2k fucking wasted.

        If I’d taken the time to call around and figure this out beforehand or picked a school that arranged the apprenticeships, wouldn’t be out the time and money.

        I’m not upset about it, I know more now and there’s plenty of dubious electricians that will inspect my work and sign off on it if I need to do anything. Plus I’m in mental health now which is my real passion.

          The local schools exist, so why would anyone really think to check if a school is locally applicable? It’s a type of problem I see often, in general: you wouldn’t have known what precise things to research until you’re faced with the actual problem. Sometimes kind and scarred souls will blast their warnings across the relevant initial source of information, but most people just move on.

          But, that being said, that’s not a terrible amount of money for, presumably, a ton of relevant knowledge to any homeowner or home owning friends. I’d love some electrical knowledge and confidence, spent all my point son automotive. But I’m glad you found more passion in a different path, too.

        Unions are fantastic. The problem here is that after spending 2k and a year learning, I was told that the only way I could get the apprenticeship hours needed to get licensed is to spend another 2k and another year going to a different school for the exact same class using the exact same books because no one in my area will take you on unless you use this school.

        I cannot test out, I cannot transfer credit, I cannot skip it. Because this is the standard in place and going against it violates their agreements with the union, I cannot work in my city. I’m all for unions, but any organization can be corrupted and this is exactly what it is.

        I think it’s a matter of how it’s framed.

        It was already going out of fashion in schools when I was growing up, and people did not like it when a teacher (usually older) made them practice it. The original argument of it being faster didn’t apply once computers became common in schools/homes, and printed letters (writing like a typewriter) are better for clarity.

        However, I think there is value to it when framed as an artistic skill. Calligraphy strengthens motor skills, and if you make the lesson less rigid then kids can have fun with it and figure out how to express themselves.

    All the useless mathematical technics from studying physics at university. Now working in software engineering, I barely use more than highschool math, sometimes.
    Instead of spending weeks writing down equations I wish I had learned more about science history, breakthrough experiments, other sciences etc.
    Those maths are only useful for a tiny percentage of the students that will eventually become theoritical physics researchers.
    It’s the curse of studying science in France, it’s unnecessarily math heavy.

      I used to work for a software consulting firm and one of our clients was NASA. Nothing exciting, just replacing an expensive proprietary system written in a commercial language with an open source one used for analyzing data from the Parker Solar Probe (PSP) and the then to be launched Interstellar Boundary Explorer (I BEX).

      The maths were so far beyond my two time community college drop out, barely graduated high school, self taught background I couldn’t even explain them. Fortunately we used paired programming and had enough mathemagitians on staff I never had to deal with the maths alone. My contribution was mostly UI and data visualization.

        If I had to do it again, I’d start with the end goal and work backwards. It was a long time ago, I was single with no extra expenses, had a decent job, and thought it might be fun to learn. If I had wanted to become a professional pilot, the calculation would have been very different.

        Getting the cert mainly involved putting in the hours. Having a good instructor helps a lot. Also, not making any stupid mistakes. I almost stalled the plane hard on my first solo touch and go. The hardest part was getting used to the ATC lingo and not stuttering too much. I got an aircraft band radio with a headphone and joined all the weirdos who liked to sit at the end of airport runways.

      At least you didn’t go all the way through Instrument rating and Commercial license, only to realize ADHD was a thing and also not treatable while maintaining a medical.

          I believe for even a third-class medical a pilot needs to be off ADHD medication for over 4 years, with additional screening/testing involved if they have been prescribed. My knowledge is limited since I have never been prescribed such meds and only realized I have some level of ADHD due to my son getting a diagnosis. He only took the meds for a year or two in elementary school before he opted to stop due to side effects and his brain overcoming that developmental hurdle.

          It sounds terrible, but my advice would be that unless your ADHD is severe enough to demand medication you should never ever tell an Aviation Medical Examiner or standard doctor about ADHD suspicions if flying is something you want to do. I could technically still go fly if I found the time, and have never felt I was distracted given the degree that flying a plane engages all parts of your brain.

          There is a dark side to this way of thinking though, as any sort of deviation from the norm with mental health or cognitive performance is often pushed under the rug instead of being treated due to fear of losing livelihood. A tragic example was Germanwings Flight 9525.

    Making tofu from scratch. Also sourdough.

    I love cooking in all forms, and there are a lot of things I happily do from scratch. I love baking bread, making my own oat milk, mixing up my own seitan from vital wheat gluten, and a whole bunch of other things.

    But making tofu was something I tried a bunch of times and have ultimately given up on. It is extremely time consuming, very difficult to get right, and makes a worse product than what I can buy at the store. It isn’t even cheaper to do, as the cost of the soybeans and the cost of the premade tofu are about the same. I may make it on occasion if I plan on serving it on its own as a dish with soy sauce, but that is about it.

    With sourdough, I found it easy to get into, but my husband and I both prefer our baked goods to be not sour, and we both have pretty sensitive tastebuds in that regard. It is easier for me to just use instant yeast whenever I need it and make something we both prefer to eat.

      One day sourdough is not sour, and still easier than using commercial yeast. When I’m making sandwich bread I do it in a condensed timeline and the starter just works like a more robust version of yeast. You don’t have to make “the sourdough” as my kids call it (they ask for it because they like it but I do understand y’all’s preference.)

      I use my starter to make bread, cinnamon rolls, donuts, once a puff pastry that was so annoying to make but maybe the best thing I’ve ever tasted. I just don’t buy yeast anymore.

    Probably morse code. It was required for my ham radio license back in the day to read it at 10 WPM. I put quite a few hours into learning it through the koch method.

      My limited experience listening to ham radio operators with my scanner (listening to voice, not Morse code) is that when hams do get in contact with each other, they mostly talk about ham radios. Which, I mean, I guess is understandable, since it’s a common interest to all of them, but a lot of it is people who like building and tinkering with radios talking about building and tinkering with radios.

        That’s often the topic on your local repeater or 80m ring.

    I got my Realtor’s license without realizing just how much it cost to break into the business. I did it for a year, and then dropped it.

    That’s the only one I can think of. Typically, I don’t learn on spec, I learn as I go, “on the job”. So, what I’m learning is directly applicable to what I need to do.

    For instance, I recently refurbished an old, cheap desk. I learned to apply laminate with contact cement. It’s not hard, but it was my first time doing it. A few weeks later I’m at a counter at a business and they have laminate that is separating from the base, and I knew exactly why. They told me that someone had been hired just a few weeks earlier to repair the same problem, and it happened again. I knew how to fix it right, but I didn’t need a job so I just commiserated with them.
