Linux Applications Programming by Example: The Fundamental APIs (2nd Edition)

📝 Discussion Summary (Click to expand)

Expectation of free material – NewsaHackO asks, “Of course, I saw that, but if the text of the book is not freely available, then the examples wouldn’t really be helpful, no?” while chii adds, “So buy the book? The expectation of free stuff is all too common.”
Value of practical, accessible examples – tad_tough_anne notes, “I often consult NetBSD's source tree for when I want good examples that aren't as complex as GNU's.”
Alternative resources & language debate – up2isomorphism questions the choice, saying, “Why would someone want to learn Unix Programming using OCAML? Not a smart choice.” – jacobgeorge08 counters with, “Thanks! I just started the OCaml Programming Book this week…”
