Private Browsing Validation Steps

asuth's Cache API Private Browsing Validation Steps

Note that all steps are being perform on Ubuntu linux with the following packages installed:

  • binutils-x86-64-linux-gnu for the strings command line tool.
    • Note that llvm also provides a strings tool, for example the llvm-14 package provides llvm-strings-14 which is equivalent for our purposes.
  • coreutils for the od command line tool.
  • ent for the ent command line tool whose homepage is https://www.fourmilab.ch/random/ (but whose debian package has diverged).

Out of date notes on shutdown

Browser Shutdown, how does it work?

General Overview

  • The parent process goes through a number of observer notifications that trigger different phases of shutdown. Traditionally, each observer would spin its own nested event loop until it was satisfied shutdown had been completed, resulting in serialized shutdown with a lot of potential inefficiency. We're now moving to using the AsyncShutdown mechanism which tells all its consumers about a phase in parallel and then spins a single event loop until they all report shutdown completion. If they don't do so in a timely fashion, a crash

xdotool window hotkey bookmarking

Two shell scripts to bookmark and restore bookmarks for windows. Based on exact window id's.

You then use these in your desktop environment's global keybindings. For example I have bound:

  • Alt-Super-1 to "bookmark-window-as 1"
  • Super-1 to "bookmark-activate-window 1" And so on for all digits. You could also use letters or whatever you want.

Note that if you don't want bookmarking and instead just want Super-F to always bring up your Firefox window, you want to do things like directly invoke "xdotool search --class firefox windowactivate" (which is literally an example I just ripped from "man xdotool").
