__cplusplus Values

Since it's impossible to find one concise source anywhere, as far as I can tell:

/*
 * m1cat: a proof of concept for the M1RACLES vulnerability in the Apple M1.
 * 
 * This program implements a covert channel that can be used to transmit data
 * between two processes when run on the Apple Silicon "M1" CPUs.
 *
 * The channel is slightly lossy due to (presumably) the scheduler sometimes
 * scheduling us on the wrong CPU cluster, so this PoC sends every byte twice
 * together with some metadata/framing bits, which is usually good enough.
 * A better approach would be to use proper FEC or something like that.

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).

Setup

git clone <repo>

clone the repository specified by ; this is similar to "checkout" in some other version control systems such as Subversion and CVS

Add colors to your ~/.gitconfig file:

willeccles

public static void main(String[] args) {
	// this uses a java 8 feature called method references (i think)
	// it looks for method "aThingToDo" in class "methoding" (the name of this class)
	// aThingToDo must match the pattern, as doAThing says
	doAThing(methoding::aThingToDo);
}

// define a pattern for what type of method we want
// we want a method with String s as input and no return (void)
public interface voidMethod {

// while this is not technically a method, a Runnable is close enough for me.

// this method wants a "method" as an input
void canHazMethod(Runnable methodToRun) {
	// run the method passed in
	methodToRun.run();
}

// this is the method I will use:
Runnable myMethod = () -> {
