What is the Strict Aliasing Rule and Why do we care?

(OR Type Punning, Undefined Behavior and Alignment, Oh My!)

What is strict aliasing? First we will describe what is aliasing and then we can learn what being strict about it means.

In C and C++ aliasing has to do with what expression types we are allowed to access stored values through. In both C and C++ the standard specifies which expression types are allowed to alias which types. The compiler and optimizer are allowed to assume we follow the aliasing rules strictly, hence the term strict aliasing rule. If we attempt to access a value using a type not allowed it is classified as undefined behavior(UB). Once we have undefined behavior all bets are off, the results of our program are no longer reliable.

Unfortunately with strict aliasing violations, we will often obtain the results we expect, leaving the possibility the a future version of a compiler with a new optimization will break code we th

m3u8 Downloading

1. Open Chrome Developer tools and click the Network tab.
2. Navigate to the page with the video and get it to start playing.
3. Filter the list of files to "m3u8".
4. Find master.m3u8 or index.m3u8 and click on it.
5. Save the file to disk and look inside it.
6. If the file contains a single m3u8 master url, copy that one instead.
7. Run the program m3u8x.
8. Paste the same m3u8 url in both textboxes (URL and Quality URL) and click "Headers" and set the referral url and user-agent from the request as found in Chrome.

Linux command to hibernate and then reboot into a different OS

In this document I describe my setup about how to add a menu shortcut that will hibernate and reboot the system into a different OS (in my case, Windows), and then restore linux on the next reboot.

For this, I'll be using Arch Linux with systemd-boot as my boot manager, but in practice any bootloader that handles the LoaderEntryOneShot (a.k.a. BootNext) efivar should work.

NOTE It is advisable to not do this with window's fast boot feature active, since alternating the hibernation of two systems can cause shared partitions to get corrupted. However, if additional steps are taken in order to ensure the shared partition are unmounted before reboot, or no partitions are shared between the two OSs, this can be made to work with fastboot enabled which should give quite a boost in Windows' startup time.

Set the LoaderEntryOneShot/BootNext EFI variable
