You are thinking of errata, and most technical books do have it.
I meant a issues web page like bugzilla or github.
Oh that's is so cool !!! I have read a few O'Reilly books how did I never noticed this.
Technical books have long had errata pages, but often with new issues, known errata are usually fixed. And as mighty as their may be, editors can't list errors that haven't yet been identified. To be in errata, it has to be found too late to fix, but not too late to change.
They often do?
What book(s) are you referring to?
Do you mean a kind of introduction-style insert that addresses things a revision would state?
A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.
