How to emulate virtual methods in Go

	// Package main demonstrates how to emulate virtual methods in Go.
	// This implementation doesn't show what the constructors should be; nor does it practice proper information-hiding.

A method of propagating cancellation signals to a context

	package signalprop

	import (
	"context"
	)

	func PropagateCancel(ctx context.Context, done chan struct{}) (context.Context, context.CancelFunc) {
	ctx, cancel := context.WithCancel(ctx)

MichaelSnowden / map_dag.c

Created August 14, 2020 03:36

A pattern for applying a map function to a dag in C without using malloc.

	#include <stdio.h>
	#include <zconf.h>
	#include <stdlib.h>

	typedef struct IntNode {
	int leaf;
	int value;

MichaelSnowden / json.c

Created July 29, 2020 04:09

Comparison of jsonArray printing methods. I have no idea why, but for some reason the generic approach is virtually the same speed as the specific approach. Almost as if the function call overhead is negligible.

	#include <stdio.h>
	#include <stdlib.h>
	#include <time.h>

	typedef int Foo;

	// repetitive approach
	int foosToJsonArray(FILE file, Foo foos, int n) {
