aperezdc / cue-and-audio-to-mp3s
Created May 15, 2013 08:45
Splits a single audio file and a corresponding .cue file describing the tracks from it (as generated by some CD ripping/recording tools) into MP3 files, cutting the input file in the time point specified in the .cue file. Usage: ./cue-and-audio-to-mp3s input.wav < input.cue
#! /bin/bash
set -e
indexes=( )
titles=( )
read_indexes () {
local -a line
local tmp
local in_file=false

Last active December 22, 2015 21:29
Edits the the Nook Color initial ramdisk of Android 4.3-based ROMs (e.g. CyanogenMod 10.2) to mount the internal eMMC data partition to be used as an “SD card”. You need to run this script from an Unix system (e.g. GNU/Linux) with your device connected. The tools “adb” and “mkimage” (from u-Boot) must be installed.

aperezdc / clock.cc
Last active December 27, 2015 11:39
Simple micro-benchmark to know which is faster: a virtual method invocation, or calling through a function pointer + userdata pointer (the userdata is meant to replace the usage of subclasses and also replaces passing the “this” pointer implicitly in virtual method calls).
