Resize a Hard Disk for a Virtual Machine

Our Virtual Machines are provisioned using Vagrant from a Linux base box to run using VirutalBox. If the Hard Disk space runs out and you cannot remove files to free-up space, you can resize the Hard Disk using some VirtualBox and Linux commands.

Some assumptions

The following steps assume you've got a set-up like mine, where:

coolbrg

package main

import (
	"fmt"
	"io/ioutil"
	"log"
	"net/http"
	"os"
	"sync"
)

coolbrg

package main

import "fmt"

type myInt int

const unTypedC = 20
const typedC int = 30

func main() {

coolbrg

package main

import "log"

func alterValue(val interface{}) {
	INCR := 10

	switch i := val.(type) {
	case nil:
		log.Println("Nil value")

coolbrg

package main

import "log"

type EventLogger interface {
	Log() int
}

type EventA struct {
	Id          int

Distributed Read-Write Mutex in Go

The default Go implementation of sync.RWMutex does not scale well to multiple cores, as all readers contend on the same memory location when they all try to atomically increment it. This gist explores an n-way RWMutex, also known as a "big reader" lock, which gives each CPU core its own RWMutex. Readers take only a read lock local to their core, whereas writers must take all locks in order.

Steps to perfoms on host

• Get Service Token (Ignore `Connection to 192.168.121.161 closed.` from the output)
