I got bit by unique_ptr when implementing a linked list today. You need to be careful to manually release() the unique_ptr before resetting or you might accidentally free the entire list. This comes up when doing insertions and stuff like that.
Filmed some screencasts today explaining some interesting behavior with /proc/self/mem — you can use it to write to unwritable memory (including the text of libc!).

With the recent announcement of Apple Silicon (Apple laptops shifting to the 64 bit ARM architecture), it’s a great time to finally learn ARM64!

What made it click for me is realizing that sales can be lost purely due to copy and design.
