Learning the Dvorak keyboard layout.

It seemed worth it at the time when I was playing a lot of monkeytype and I still love typing with it. But I made the full switch and forgot how to touch type with qwerty. So now I have to switch layout every time I use hotkeys and switch back to type. Switching is fast but an extra step.

I decided to switch because I think it's a superior layout but honestly it's not even that worth it. You will not gain speed, just more comfortable and satisfying.

Belly-dancing. So difficult, and not even really fun.

People pleasing, spent nearly four decades getting so good at it thinking if only I could be just that little bit “more good” that I’d get what I want and need from people and relationships only to realize I’ve been plenty good this whole time, it’s a fools errand and I only attract people who will move the goal posts every time because it’s what I expect and have trained for

SystemC simulation, for school.

This was well over a decade ago now and the libraries we were using were absolutely ancient at the time. We had to simulate a game. I absolutely hated it.

If nothing else, it taught me how to deal with linking error induced headaches (weed)

I learned how to work hard and be good at my job and actually get things done, not just look busy and act important.

Jokes on me, the entire management make 100x more than me and do 100x less. And they get to spend hundreds of millions on stupid projects that are horrible ideas, but I have to cut back on my area to save $100.

I should have put all my stat points into soulless bullshit corporate jargon and none into intelligence.

Descriptive Geometry.

Basically obsolete by the time of mastering the techniques due to CAD software.

Here's lesson notes from somebody.

The field starts out simple with orthographic projections, but later you work on problems like : you have a top view of a 3D tube angled in space and another tube crossing it at an arbitrary angle, and then another view.

Find this smallest distance between the two tubes in space.

Neither are down the tube axis, so you start the process if finding the axes and producing a head on view to develop the crossing tube to then find a point to point minimum measure between the two cylinders.

By the time I'd gone through all this, in CAD you just click the two tubes and ask for the distance (min or max)

The vast majority of higher math and some industry-related chart interpretation as far as aviation goes.

I guess I’m probably older than 95% of the people here, so all the “spaghetti” charts we had to figure out, the actual trigonometry used to calculate wind correction angles, all of the math used to calculate EPR, thrust, and Mach speeds. Instruction in these calculations was very demanding and unforgiving. Then it all pretty much became useless as I followed the leading edge of software development and electronics moving into the cockpit. So I learned it all only to have it disappear within a few years.

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.

I got a bunch of software certs for when I was first job hunting and now they either no longer exist or have been so changed that the certs don't matter.

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.

Gained the year Win2k dropped

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.

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.

At the end of the day I'm just not very interested in getting a lot of contacts. I just like building and tinkering with radios.

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.

Taught myself how to snake spit. But now it sometimes happens on its own so I really wish I hadn’t trained my mouth so well.

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.

Getting a private pilot certificate. Was fun, but after going to every airport within range, not sure it was worth it.

Ventriloquism. I dont use it at all anymore. Learned it because i thought it would be fun and one could make some jokes with it but nah

I honestly can't think of any, even though I have many examples that objectively seem to not have been worth the effort.

Easiest example is flight school. I went to a tech college for its professional piloting program. Got my private pilot cert and multi engine rating, and completed IFR in the simulator. But when it came time to sign up for IFR in a real plane, I couldn't get approved for enough student loans to cover the cost, so I dropped out, switched to business school, got a tech job, and dropped out of business school too.

By all accounts, the debt I racked up (like $75k) and the pilot license I haven't exercised in 14 years are all a huge waste. And my flight instructor was such an impatient ass that I feel mildly scarred from the times he yelled at me.

But, I will never get over the massive feeling of accomplishment I got from earning my private pilot certification. And even more so, earning my multi-engine rating. Even if I failed a part of each of those checkrides and had to retake those portions, I passed them. Even if I never fly again, I am so fucking proud of myself for earning those.

I guess since I never actually graduated from any of the many colleges I've dropped out from (three or four depending on how you count), pilot license is my closest analog.

Also have a CDL and skill with docking 53 foot trailers, and tons of forklift experience. Those haven't been used in a very long time and I may never use them again, but still feel like important parts of me.

Let me think -

Mostly software training at work for systems they immediately abandoned.

My interior design skills languish for lack of money.

Most of the other stuff I can do gets some use I think.
