// Minimal audio streaming using OpenSL.

// Loosely based on the Android NDK sample code.
// Hardcoded to 44.1kHz stereo 16-bit audio, because as far as I'm concerned,
// that's the only format that makes any sense.

#include <assert.h>
#include <string.h>

// for native audio

Motivation

• Make testing new releases easy for me. No tedious reinstalling of my common apps
• Some graphical customizations for nerdcred
• Ability to patch things
• Deeper understanding

Plan

• Be as vanilla as possible for easy version upgrade

object Main extends App {

  println(isBalanced("(.)(.)".toList))

    def countBracets(string: List[Char], count: Int = 0): Int = {
      string match {
	case '('::tail => countBracets(tail, count+1)
	case ')'::tail => countBracets(tail, count-1)

Goals

This documents tries to address some concerns with enabling PIE.

Argument 1

One of the criticism of "Using PIE by default on AMD64" is,

function dex-method-count() {
  cat $1 | head -c 92 | tail -c 4 | hexdump -e '1/4 "%d\n"'
}
function dex-method-count-by-package() {

  baksmali $1 -o $dir
  for pkg in `find $dir/* -type d`; do

    name=$(echo ${pkg:(${#dir} + 1)} | tr '/' '.')

ANNOUNCEMENT

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!
