I'm looking for the source code paired with a textbook, but the URL provided in the book has rotted away, and searching Google only reveals sources that don't appear to be official or have been modified.
Is asking for the location of this software on-topic? It pretty off-topic for Stack Overflow, and this seems like the closest alternative, but I'm not sure how the community feels.
On the one hand, they're not really recommendations. On the other, this is definitely useful information, and it's often hard to find, particularly once a link rots away.
Example questions:
- Where can I find the online resources that came with Effective Java?
- Where is the canonical source code for Java 8?
- Where can I find any source code released with the original Google PageRank whitepaper?
