Would be the following questions acceptable on Programmers site:
Few years ago book XYZ by AuthorSoAndSo was considered the book on ABC. Is it still the case? Has it become outdated?
In job posts I often see a requirement to be proficient with SuchAndSuch type of applications. What are the main concerns with these applications? What kind of tooling should a programmer become intimately familiar with to claim such proficiency?
Are the above questions specific enough to survive?
