When you post on reddit, instagram etc. you're giving the company your valuable data. (And it often is valuable, you put your thoughts into it and all that). Consider if you take 15 minutes to create value content, you'd get paid $5 or sth if you were doing it commercially. Now all that value is donated to big tech companies. (that's the only reason why they have value at all.)
So what's the problem with that? The problem is that reddit and others can instantaneously put your years-long effort behind a paywall. I'm not joking. Look at these:
when i want to see content on reddit (for research) or instagram (for local community) they don't allow me to see the data that users have contributed. Reddit claims that it blocks VPNs for "security reasons", meanwhile i'm using VPNs in browser's incognito mode to not be tracked. Instagram wants you to sign in sothat they amass more users and can take leverage of the network effect even more.
I can understand restricting who can post to limit bot activity, but reading must always be possible. After all, it's our data. That's exactly what happens when you give your data to big companies to "communicate with other people": your data becomes a source of income for them, at our expense.
It's pointless anymore to try infoposting on reddit.
Take for example the soldering subreddit. The info on that sub is that you must slather everything in flux in order to solder properly. A guy posted yesterday citing 40 years of experience, saying that's not how he's done it. The comments are a mess.
Another post today, someone asks about air filtering the solder smoke. The consensus in the comments is it's not a big deal. You can literally measure the particulate matter yourself to see how bad it is. Basically an average residential room size, say 100-200 sq/ft. You'll basically hotbox yourself with smoke.
Another one that's seen less often but the false idea persists. It's that capacitors never short and burn out. I don't know how or why that false idea floats around, but I've seen it over the years. I've replaced tons of caps that spontaneously combusted. Both electrolytic and SMD caps. Sometimes they just fail and short. No other fault.
Reddit is full of bad info. It's site that relies on word of mouth and popularity contest. You do not build a knoweldge base of technical information this way. You're getting an entropic game of telephone. That's all reddit ever was and ever will be. It's flawed paradigm by default.
A paradigm that lemmy is built off. So don't you all be getting the idea that good knowledge is going to be getting sourced from here either.
As a long time maintenance technician, this made me unreasonably angry. This is something I would punch somebody for asserting.
It is also one of the first things you learn when experimenting with capacitors. You burn a few while building faulty circuits.
Right after having burned a few resistors.
The second thing we learned in electronics class was that putting a 12v cap in a mains line makes a really loud bang.
Our benches were left unplugged every day and when we came in, we were to plug them in.
This devolved into finding ways to hide caps in the outlets in each other's benches and a desire to show up very early to class.
O.o
I've been in it since the late 90's, I feel, at most, like peeing in their shoes when they're not looking.
They won't learn anyway, least you can do is make them uncomfortable for while.
