Which posts are unexpectedly popular in your dev blog or wiki?

For example in my case, I was expecting much less attention for my "top" pages like:

- building Subversion from sources on CentOS / Ubuntu - when git supposedly ate everything

- Properly install Wampserver 3 (LAMP stack for Windows) - when WSL is so popular

- How to play around with PCem (abandoned old PC emulator) - when DosBOX does the trick almost for 99% of the cases

Yeah, perhaps it's really influenced by being linked on reddit or other sites, but you know, there is actually some more people than you thought, interested on those pages...
