What I love about this is that it's a textbook example of a reflection DoS attack ( https://en.wikipedia.org/wiki/Denial-of-service_attack#Refle... ) - you send a message with a spoofed reply-to address, such that t

My solution for this is a script that commits all my changes then tags the resulting commit with a basic descriptive name. Something like this: git discard bad-idea-didnt-work Which creates a tag discarded-bad-idea-didnt-work, then

To add to sibling comments which describe various uses of `git add`, I'll also recommend `git commit -a`, which adds all changes from tracked files (but unlike `git add .`, not untracked files) before committing.

There is value in "making a decision" for each untracked file, of whether to explicitly add it or ignore it. This combines well with things like a PS1 that indicates if you have any unclean state (including both changes and untrac

This reminds me of how useful it is to make your ids include the type of the thing they're identifying as part of the value. This could be as simple as something like "u<random digits>" for users, "p<random digi

Python has always had the ability to do callbacks (ie. first class functions), though admittedly it's not a common pattern and the stdlib doesn't support it for IO (also its anonymous function syntax is poor). There have been seve
