Had someone contact me because a browser interface was ‘down’ and it was actually a cert issue. It surprised me that in an IT context, this person didn’t have a basic understanding of SSL certs. They didn’t even know how to add a cert exception.

It got me thinking, what basic ubiquitous things am I a dumbass about outside of IT?

Ive seen lots of ‘fun facts’ compilations, but it would be better to get a wide range of subject suggestions that I can spend 30 minutes each or less on, and become a more capable human.

Like what subjects would plumbers consider basic knowledge? Chemical interactions between cleaning products and PVC pipes?

What would an accountant or a landscaper consider to be so basic its shocking people can live their lives without knowing any of it?

For most areas of expertise, its difficult to know even what the basics are to start with.

    Don’t use high heat on nonstick pans.

    Assuming we want the same internal temperature, high heat will cook the outside more than low heat. For bread you probably want a bit more heat to get a nice crusty outside. For steaks you want less heat to avoid overcooking most of the meat, then just a quick sear on the outside.

    Don’t overload your pan. If your food is cooking in a bunch of water that came out of the food you are boiling it, not frying it, and it’s going to suck. Put in less food so that water can boil off before it starts boiling your food.

    Don’t overload your cookie sheets either. The center of the pan will not get as hot due to all that cold wet food sucking up all the heat, so the fries on the edge will cook faster than the fries in the middle.

    Sear or roast your brassicas. They taste way better with some browning and lots of oil and salt.

    Measuring food by weight is much easier and much more accurate than measuring by volume with measuring cups and spoons. This is next level awesome if you’re trying to measure something sticky like honey or peanut butter, you can weigh it in the mixing bowl rather than dirtying a measurement device.

    Don’t overvook your meat. Use a fast read meat thermometer. Beef, pork, chicken, seafood, are all much better when cooked.to the proper internal temperature.

    I am not a cooking expert, I am a heat transfer expert with a strong background in chemistry and those skills transfer over to cooking.

      Just adding to yours as I’m a nerd for gardening and it isn’t common knowledge: brassicas are vegetables like broccoli, cabbage, mustard, etc

      Also on the topic of brassicas, if you see the little white “butterflies” with a black dot on each wing, those are cabbage moths and the bane of a gardeners existence! Unless an entomologist can chime in and say why they’re actually great lol

      I find high heat in stainless steel pans is very good though? Like it works better to heat the pan and then add your oils. They’re so much better.

        Definitely. I agree that in stainless, it is best to get hot first, then add oil, then add food. It is also best to let the food sit still for a bit on the heat, as it browns it will naturally start to detach to flip or remove. Same works for cast iron but easier

    I honestly have no idea what your first paragraph is about. It might as well be in Chinese.

    I’m a molecular biologist. I was recently surprised when I told someone that RNA is a thing that all living thing are brimming with. He thought that RNA was something scientists invented in 2020s to use as COVID vaccines.

    I also once worked with someone who had a degree in biological sciences and was shocked to learn that female cows have vaginas. She didn’t explain where she thought baby cows come from, but we decided not to push the matter and changed the subject.

      ELI5 of certificates:

      The “s” in “https” in urls like “https://wikipedia.com” stands for “Secure”.

      When you connect to Wikipedia’s computer to read something, how do you know if the content you get back is what they actually sent and wasn’t altered by your friendly neighborhood hacker?

      Wikipedia can “sign” the content before sending it you. They also give you a certificate telling you how they have a particular signature which has been verified by someone else whom you already trust, and how long this particular signature is valid for.

      If a hacker tries to alter the document returned by Wikipedia, they wouldn’t be able to sign the document correctly. If they tried to give a certificate with a different signature too, you would catch it because they wouldn’t be able to fake the verification of the “someone you trust” so you’d catch the fake certificate.

      Browsers handle all this stuff for us. If it detects something fishy, it’ll just show an error along the lines of “could not verify certificate”. In some cases, it’s genuinely an issue where you/the website is under attack and you may get a virus.

      In some other cases though, it’s an issue of the certificate expiring and the guys at Wikipedia not being proactive about getting a new signature and certificate. If you are ABSOLUTELY CERTAIN that you’re just dealing with a lazy developer and not a malicious hacker, you can tell your browser to ignore whatever issue it detected and show you the content that was returned by Wikipedia.

    Basic knife skills is something I’m often almost shocked by. I had a housemate last year who’d bought herself a decent Sabatier chef’s knife (like this) but the way she cut veg, she may as well have been using a sharpened bit of moss. All the gear and no idea. Thankfully she forgot to take it with her or something when she moved out so it’s my knife now.

        For onions specifically:

        Sharpen your knife and make French onion soup.

        You’ll cut so many that you’ll figure it out.

        For everything else: pinch grip and crab your other hand. The pinch grip is where you rely on a pinch between thumb and forefinger on the blade just in front of the handle to grab the knife. It’s the choke up of holding a knife and will make you much safer and give more control. Crabbing your other hand is where you curl your fingers up like ginger roots instead of letting them extend out like little baby carrots. It will keep you from being hurt when something goes wrong and allow you to go much faster because you’re not having to slow down to avoid cutting yourself.

        Keep your knife sharp, remember that you cut by running the blade along something rather than pressing into it, and keep your fingers out the way by doing the claw with the other hand and keeping your grip firm. Then just practise!

    Processes

    Super generic, most people interact with them in some form all the time both at work and personal without a second thought. Very few understand what makes a good process, especially when there is a handoff involved.

        Mostly it’s about best practices I think, and getting a feel for them. Try starting with something simple, like making a peanut butter and jelly sandwich. Describe how it’s done, each step. Think about where it’s efficient, where there’s extra wasted action, or time. By the time you’re done you’ll be considering if your butter knives are stored in the best spot, if you should get everything out at once, or one at a time. Do you have enough inventory? Is having extra inventory a waste? Is it worth washing knives afterwards or get extra so you can wash a batch at a time instead?

        Then, go back through from the perspective of a child that has never seen your kitchen. Do the steps still make sense? How can you make it more simple, less effort? Finally, when I mentioned hand off… How do you ensure that your child laborer is going to deliver a pb&j of sufficient quality? Who determines quality? Production time?

        Once you start thinking that way, everything is a process that could be considered, with inputs and outputs, quality control issues, potential waste, efficiency improvements, etc. It applies to data just as much as a sandwich for example, and office jobs are all about taking information, changing it a little and sending it on. Each step should transform in some way (capturing who does what, to what, at each step can help). Understanding the complexity instead of assuming simplicity so you can analyze it, but then distill it back down to something that is actually simple and understandable.

        Anyway, hopefully that helps some in thinking about it a little differently.

        For googling key words: quality management, process mapping, process analysis, lean, ?

        Unfortunately there’s a lot of corporate shit, buzzwords, and SEO that have accumulated so it can by hard to find good info (like everything else now?)

          This is really interesting and a good way to think about a bunch of things. I’ll try it out. I do pay some attention to processes, but not to granular detail.

      Are you talking about the meters that simply detect whether wires are still live or not? Definitely a good backup to double check that you’ve shut off the right breaker.

      If you’re talking about a single lead multimeter to measure voltage, I’ve never heard of such a thing and don’t know how that would even work.

        There’s literally no such thing as a one-lead voltage meter. Voltage is, by definition, the difference in potential energy between two points.

        Any tool that can give a voltage reading with one probe has a second probe you’re not considering, or is estimating voltage based on a some assumptions about current or some other factor being measured.

        This one can detect voltage with a single lead and also works as a voltage meter if you use two leads: https://www.benning.de/products-en/testing-measuring-and-safety-equipment/test-equipment-voltage-tester/voltage-tester-duspol.html

        It also has an inbuilt motor to distinguish leaking voltage from continuous AC.

        Sorry if I didn’t use the correct English terms and that wasn’t clear enough.

        In Germany you simply call it a Duspol and every electrician knows what you mean. Didn’t research enough into the English description but it seems it’s a two pole voltage tester with one pole voltage detection mode.

    The sales are continuous at Lowe’s. Probably other stores too, but I can say that I worked for Lowe’s for about 15 months and during that time we always had a sale going.

    It’s a ruse to provide an artificial sense of urgency. One sale would end say 1/13 and on 1/14 we’d take down all the signage from that sale and put up the signage got the next sale.

    I’m constantly amazed at how many people don’t understand the concepts of basic finance and how compound interest works.

    Years ago, I brought my laptop with me to buy a car so I could plug all the numbers into a quick amortization schedule. The sales person offered me a choice of $1,500 cash back or 1.9% financing instead of the typical rate a few percentage points higher.

    I plugged the numbers into my spreadsheet and saw taking the cash back would cost me a couple grand more than the lower finance rate. When I told him I wanted the finance rate instead of the cash back, he mentioned that I was the only person he’d seen not take the cash back.

    Maybe he was pulling my chain, but in my experience, the average person doesn’t know what compound interest is, let alone what an amortization schedule is.

        For microsoldering: you want the quick 861dw or one of the knockoffs and a bunch of tips. Sometimes you can get away without a microscope but usually you need one of those too. You need a swing arm mount for it because you often won’t be able to position your board under the objective of a tabletop mount.

        You 100% cannot get away without a fume extractor. You’re gonna need low melt solder and flux, so you also need to be wearing disposable gloves.

        You need a board holder because once all the solder in the area is liquified you don’t want the heavier parts sliding off the board because it’s propped up on a piece of wood at a ten degree angle.

        If you wanna extend the amount of work you can do with just a decent iron: use flux and low melt to get everything on your usbc liquid at the same time so you can lift it off the board.

        Learning about cars, engines and motorbike maintenance at this stage in life really opened my eyes. I could have easily been a mechanic or an engineer if I had the access to this knowledge when I was younger.

        Now I do as much of my own maintenance as I can, and I’m pretty sure my engine will hit 400K before I start getting serious issues. None of it is overly complicated or difficult, and saves me money in the short and long term.

      That’s wild. When I was getting a mortgage for my house, the lender was like “your interest rate is X, but if you pay $Y you can add a ‘point’”. I’m like “wtf is a point?” Turns out, it’s a roundabout way of saying, higher down payment = lower interest rate.

      It already wasn’t obvious what their jargon meant, so for you to have a sales person offering the exact opposite of what my lender did, actively bribing customers to take a worse deal for themselves, it’s just…scummy.

        Yeah, buying points is a bit different though and again is a great example of why everyone should at least have a basic understanding of how to make an amortization schedule.

        Buying points isn’t exactly the same as a higher down payment, because that money doesn’t take any principal off your loan. It’s basically paying interest up front, giving the lender a lesser amount now rather than a greater amount later.

        Shit gets complicated real quick, so plugging it into an Excel spreadsheet makes it much more clear.

        You can also use an interest calculator or multiply the payment by the term length to see how much over the purchase price you’ll pay in interest.

        This is why it’s important to haggle over the purchase price and not the monthly payment. Never ever negotiate over the monthly payment, or you’re likely to get stuck with a 96-month loan at 23% interest.

      Have you told this story before, possibly on reddit? I swear I’ve read this verbatim including the part about the laptop and “I was the only person who took the lower APR.”

    Basic computer competency starts with reading the error message.

    I’ve worked in IT and you’d be amazed how many people are stuck with some problem that would be fixed if they just read the error message on their screen.

    For example, it might say:

    Error! The green button needs to be pressed. It’s on your keyboard. It’s green. It also has lettering on it that says PRESS HERE.

    People will bring their computer in, at a total loss for what to do.

      The customer service manager sent not one, not two, but three emails in one hour demanding our engineers fix this login error that a high valued customer had.

      The error was “username or password was incorrect”.

      I fixed it by resetting their password.

    I’m a developmental psychologist, and the biggest thing is people just not knowing what “psychologist” means.

    The tl;dr here is:

    Most psychologists aren’t therapists. Most therapists aren’t psychologists. If you’re looking for quality mental health care, don’t revere the “doctor.”

    A “psychologist” refers to someone with a PhD in psychology (or someone who does psychological research within an interdisciplinary field, like education or human development). Critically, a psychologist is a researcher (and often an educator at the college+ level). Psychology is a massive field, and the most common subfields are cognitive, developmental, social, clinical, and neurobio.

    A “clinical psychologist” is a research psychologist is the particular subfield of clinical psychology. Along with research, clinical psychologists usually learn clinical psychotherapy practices and then may (or may not) choose to incorporate offering therapy into their career. A similar path is the “PsyD” (doctor of psychology) which also falls under the “psychologist” heading. Like a clinical psych PhD, a PsyD has had advanced training in research and practice, but the balance of the degree leans much more toward practice. People who opt for a PsyD rather than PhD usually plan to pursue a fully clinical career, but are qualified to do research as well.

    A “therapist” is someone who is trained and licensed to provide clinical psychotherapy. Most therapists in the US have a master’s degree in social work (or a few others, like counseling psychology), specialized clinical training in one or more areas or treatments, and additional state licensure requirements. Clinical and counseling psychologists (with PhDs) can act as therapists if they get and maintain licenses, but this is a small fraction of therapists. PsyDs make up another chunk, but the majority do not have a terminal PhD/PsyD.

    As a psychologist, I don’t say this because I think my PhD makes me better than someone with an MSW — the reverse! I hear people get advice to not see a therapist if they are “just” a social worker without a PhD. Meanwhile people come up to my dumbass self and think I am qualified to act as a therapist or like I know anything about clinical or abnormal psychology. Like, wanna know how 2-year-olds and 12-year-olds use nonverbal signals like shrugs to facilitate conversational interaction differently from each other and from adults? No? Then I am not the person you’re looking for. Go talk to that extremely knowledgeable and well-trained person with an MA.

    …Meanwhile a “psychiatrist” is a whole other thing. They have an MD and can prescribe medication. Very rarely they may also offer psychotherapy, but that’s hard to make happen in the US a healthcare system.

    Not really completely on topic, but there’s an app called Kinnu. It’s free, and gamifies learning- like Duolingo but for a really wide variety of topics. So far I’ve done the pathways on learning, ikigai (Japanese concept of reason for living/being), logic and cognitive biases. They have pathways on other things too, like history, various sciences, philosophies, even personal finance (probably the next one I do).

    It’s a great way to kill 2-5 minutes a day and Ive learned a ton.

    As someone who works with tech, here is my 2 cents on basic knowledge.

    If your computer is “not working” restarting the computer can generally fix 80 percent of the issues. We are not trying to make you mad, this is literraly first thing I am doing if you present me a problem.

    Stop downloading things from unknown sources.

    Use generic effects/fonts on your powerpoint. Just because you bought something cool doesnt mean it will magically transfer when you pass your presnetation to another computer for your presentation. (Microsoft does not migrate your paid effects)

    For gamers Stop playing pvp on your pc/console on wifi, are you a mad?

    Everyone in general We are at an age of computers. Learn how to type, it will save you tremendous amount of time, literally.

        Yes, i have seen it happen several times and i get blamed why its not showing on the show laptop. The moment i ask, “did you purchase any add on effects?” i feel like a customer service telling a customer your credit card was denied.

          That’s just wild. I’m in meetings with slides constantly and never heard of this. We’ll, now I have a new rabbit hole to go down (as in “finding the most ridiculous of these”).
