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

How to disable the very little-known AT&T setting that can appear to hijack your home DNS lookups and redirect to 104.239.207.44

Issue

DNS queries on home network suddenly resolving hosts to 104.239.207.44.

Symptoms

You will see SPORADIC mis-resolutions of EVERYTHING to that 104.239.207.44 address if their crappy router happens to hear your PC's DHCP request - EVEN IF ANOTHER DHCP SERVER ON THE NETWORK assigns the ultimate address.

	Nintendo Switch Joycons use standard bluetooth technology and can be paired with a PC or phone by holding the power button between SL and SR while the console is off.
	If your Switch can't find em after that just reattach them to the console and they'll pair up immediately.

	Hi guys! I've made this tutorial cuz my Driver Manager wasn't working well, hope it helps:


	1 Obviously starting with an update and upgrade:

	sudo apt-get update && sudo apt-get upgrade

	2 Then remove all Nvidia packages, skip this if your OS is fresh installed:

	sudo apt-get remove nvidia* && sudo apt autoremove
