it doesn't. it only works incidentally. The author isn't an EE and has designed a circuit as if an artist (or an AI) drew a picture of what a circuit looks like.
The weird topology voltage divider attenuates the signal. the op-amps buffer the output. The 470R resistors do nothing. The 1k/1k virtual ground does nothing.
The rest of the authors writings smell of /r/iamverysmart
once, when complaining to a colleague about our workplace and their hiring and staffing idiosyncrasies, I quipped "I should give <manager> a copy of TMMM". My colleague, without missing a beat said "You should give him two copies so he can read it faster"
I'm not sure if reading the book would help. If the manager has a technical background (e.g., they have worked as developers before) then they already know the main point of the book. If the manager does not have a tech background, then there's little that the book can do for them.
If the only important information in the book was its main point, it wouldn't have needed to be a book. It could have been a leaflet. Or a bumper sticker - those can be very catchy.
It's worth reading the book for all the other words it contains.
No, but most will at some point in their career hear about it in comment sections on HN and the like, or in many different forms hear the adage that adding more people to a project makes it later.
Many developers don't spend time on hacker news or even any of the similar forums. To be stereotypical, HN readers seem more likely to be young, working for FAANG in Silicon Valley, and not a middle aged sharepoint integration developer living in the Midwest (although obviously they are also on this site).
I've had developers who treated it like a job, did it, went home, and weren't interested in the Mythical Man Month (but intuitively knew some of these principles).
I thought about making one of these - actually I designed it, but never made the PCB for it - because the internet is full of similar ones:

There are a few dynamic pricing energy retailers in Australia too. It often goes negative, sometimes for many hours at a time. Usually it’s hard to make money off it because it’s often at times of the year and day that there is no need for heat/cooling.
In the slightly olden days, iMessage - or whatever it was called then - had a built in jabber client, and there was brief period (Sierra era?) that iMessage/iCloud could sync up all your messages across google and apple and SMS.
I _think_ it would have enabled this functionality, if anyone knew and/or investigated it.
Yep, this is when it was called iChat. I used it for that exact purpose for some time. This was before Apple had their own protocol, though; I believe it just supported AIM and XMPP.
it's actually persisted more recently. I just checked a High Sierra machine. "Messages" has an "Add Jabber Account" menu option. An it's recent enough that it plays nice with all my existing more modern iPhone/macOS etc iCloud messages.
I have once of his Klein bottles. It came in the most amazing personally decorated package that I've kept that too, and value it almost as highly as the glassware.
Once, a postal letter-carrier asked me why I scribbled “nonorientable” on my package. I began to tell her the mathematical meanings of the word, and she interrupted me to say that she knew its meaning - she wanted to know what kind of topological shape was in the box. Wow: she knew topology!
Since then, I scribble it on every box I mail, in honor of her.
