  • I have had to teach a subject in school. Part of my education was a minor where I had to teach a class for a trimester.

    I had to prepare materials (presentations, homework assignments, study material, quizzes and the exam), teach the class, answer student questions in person/mail/school system etc. There was a professor that helped me, was always present and officially taught the class otherwise the students grade wouldn’t count. But as it was my assignment the prof was very hands off and was there only as a fallback if I fucked up and to evaluate my performance. We got along pretty well and she gave me an excellent grade in the end.

    The class I taught was uni level cryptography, basically a math class. The math would get pretty advanced and a lot of the problems students had to solve required a long working out. There usually wasn’t an answer to the problems, the working out was the answer. The exam was also pretty though, but almost all of the students got a good grade and nobody failed.

    Feedback from students was that I was pretty strict, but they learned quickly and had a good time during the class. Remember these were 2nd year uni students, so discipline wasn’t an issue, everyone was there to learn and wanted to be there. Most of them were maths nerds themselves and loved the subject, which helps a lot. Ages of the students ranged 18-25. So my teaching was focused on the subject matter and not managing kids.

    Would I teach again? I don’t think so. It was a good experience to have, but I can see it get boring very quickly. Imagine teaching the same class trimester after trimester, year after year. Sure some new stuff comes along every now and then, but even in the more advanced classes you teach the basics, not the new stuff. As I enjoy the subject more than the interaction with the students, I don’t think I could do it for long.

    A couple of reasons:

    First of all what one wants in terms of faucet designs is very personal. As such there are many many models to choose from. This makes each model in be produced in relatively low quantities, and be more expensive. If everyone would use the exact same faucet, they would be basically free. And you do see some models being used in new construction that are very cheap indeed, just because of the higher volumes.

    Second of all, the tolerances and finishing involved. It’s relatively easy to make a faucet that works, the designs have been perfected long ago and modern manufacturing can easily produce a working model. However to create a faucet that feels nice, that doesn’t make weird noises, opens and closes smoothly etc. is a lot harder. I’ve had cheap faucets before, one of those single handle deals. It would take more force that I would like to open the tap, at which point it shoots open so water sprays out. The range in temperature is insanely hot to insanely cold with only a tiny single spot of normal temperature in between.

    Third reason is they are made from a lot of parts and with materials that need to be handled really delicately. Chrome finishes that scratch easily when handled in properly, leading to the whole thing becoming instant scrap. This leads to hand assembly being the only option. And often it involves a lot of small parts that need to be placed just so. This adds a lot of cost.

    Fourth reason is the materials themselves, often quite expensive to start with. Large parts being machined out of a single piece. By definition everything needs to be corrosion resistant. And it’s one of the products where we still expect them to last 15-20 years easily. Not like the consumerism that’s forced a 5 year lifespan to be called long in the modern world. The finishing coatings are often chemically applied with expensive materials and taking a long time. And a fully polished finish also takes time and is often done by hand and takes some skill.

    Fifth reason is brand names. Just like with any designer thing, brand names and designers are a large part of the costs. You can often find designer faucets for outrageous prices and cheap knock offs that can be trash or sometimes even better than the original for half the price.


  • This is usually done to keep things going as normal as possible for as long as possible. Once people start noticing something is wrong, the best people start looking elsewhere. Before you know it, not only is the company in financial trouble, but it can’t recover because some of the best people left. At least one time I witnessed, the company was working on layoff plans and even limited bankruptcy, but at the same time negotiating with the investment firm that owned part of the company to get more money. If they got the money, everything would be fine. It wasn’t till that fell through, they had to start laying people off.



  • Most of the bots on Lemmy have been well meaning, but ultimately annoying.

    The issue is there isn’t really a lot of traffic on Lemmy. And from the people that are here a lot of them are lurkers, just consuming, maybe upvoting once in a while, but that’s it. This leads bots that reply to a lot of comments/posts to become a large part of the traffic and thus the experience for the users. There isn’t enough for the bots to get lost in the noise. This also leads to the user experiencing the feeling of only interacting with bots, instead of other people. Most people commenting are looking for people interaction and get annoyed when they think they have such an interaction only for it to be a bot.

    Lemmy is also very focused of an audience at the moment, which leads to bots not really being necessary. People here are usually very tech savvy and know how to do most of the things. A bot that explains how to do things people already know how to do comes across as unneeded.

    I’ve seen it as well. A part of it is because posts get down voted, so when you scroll down it gets displayed twice since it moved in the ranking in between loading. This also means if a post gets up voted, you can easily miss it. It’s only an issue with posts that have few votes usually, so not a huge deal.

    But I’ve also seen where the same few posts just repeat twice for seemingly no reason. I’m not really sure how the data gets retrieved. With other systems I’ve seen a “session” associated with a cursor. That cursor moves through the data, maintaining the order. That way it doesn’t matter that stuff changes in between client data retrieval. Lemmy doesn’t seem to work like that, simply querying the database with filters. That isn’t the best honestly.
