When you follow the schematic but it doesn't work

Yeah all the PHP holocaust perpetrators jumped on it then.
Now it’s “package manager of the hour” territory.

I know lots of passionate people who are fucking useless.

Lol. Well there are also lots of people with a degree that are equally useless.
So i guess that's a draw.

But he has a point, you surely also know many graduates that couldn't care less.

Although I an generally quite cynical - and rarely positive, I have noticed most of this thread is pretty negative. The op has mentioned fairly specific examples (analogue, oscillators) probably build on solderless breadboard that haven't worked, and then the replies are full of "most published circuits are useless!!". And has even moved on to people claiming that students and professors don't know anything... this gives a very warped (and wrong) view of the world. Any newbie reading this thread is just going to see a bunch of old timers complinaing about how things aren't the same these days and trying to put them off learning anything. Maybe start another thread in general chat if you want a platform to whine.
I'll admit, the internet has a LOT of crap schematics that do a disservice to electronics education by perpetuating poor designs, or old designs like using the PIC16F84, or using LM324's for audio stuff. But when I started electronics when I was about 11, I built plenty of circuits out of magazines (maplin, guitar effects from the web etc..) and most worked - despite me not really having a clue how. That's more a testament to the designers of these circuits than my own (dodgy) prototyping. Some circuits are just more stable than others, and some require knowledge not only of how it works but also of the components used and their properties. I suspect BJT oscillators are more annoying than say, 555 circuits.
If a circuit doesn't do as expected, its an excellent learning opportunity - something BD139 pointed out. If one really doesn't know where to start, then that's what forums are for! (if we ignore the replies along the lines of "that's a bad circuit, try a different one"). Debugging and working out what does what is arguably a much more useful skill than just reading textbooks.
