Find the dates your debian/ubuntu packages were installed.
Find when debian packages were installed on a system.

Extract a remote tarball in the current directory without having to save it locally

Print stack trace of a core file without needing to enter gdb interactively
This does almost the same thing as the original, but it runs the full backtrace for _all_ the threads, which is pretty important when reporting a crash for a multithreaded software, since more often than not, the signal handler is executed in a different thread than the crash happened.

run command on a group of nodes in parallel
The pee command is in the moreutils package.

Quick HTML image gallery
My take on the original: even though I like the other's use of -exec echo, sed just feels more natural. This should also be slightly easier to improve. I expanded this into a script as an exercise, which took about 35 minutes (had to look up some docs): http://bitbucket.org/kniht/nonsense/src/7c1b46488dfc/commandlinefu/quick_image_gallery.py

git remove files which have been deleted
It deletes all removed files, updates what was modified, and adds new files.

Display a block of text with AWK

Detect illegal access to kernel space, potentially useful for Meltdown detection
Based on capsule8 agent examples, not rigorously tested

easily find megabyte eating files or directories

Use a var with more text only if it exists
See "Parameter Expansion" in the bash manpage. They refer to this as "Use Alternate Value", but we're including the var in the at alternative.
