JT5D / Shannon-Entropy.js
Created April 10, 2020 03:54
Calculate the entropy of a string by determining the frequency of each character, then summing each character's probability multiplied by the log base 2 of that same probability, taking the negative of the sum.
// Shannon entropy in bits per symbol.
function entropy(str) {
const len = str.length
// Build a frequency map from the string.
const frequencies = Array.from(str)
.reduce((freq, c) => (freq[c] = (freq[c] || 0) + 1) && freq, {})
// Sum the frequency of each character.
return Object.values(frequencies)

Created February 27, 2017 05:57
Script + FFmpeg command to batch-convert directory of WAVs to MP3s
#!/bin/bash
for f in *.wav; do ffmpeg -i "$f" -ab 320k "${f%.wav}.mp3"; done
#run this script on an scheduled cron job or from the command line.
#to run this script from the command line, open your terminal & cd into your folder of WAVs like so: 'cd myfolder'. hit return.
#now type 'sh FFmpeg-batch-convert-wavs-to-mp3s.sh'. hit return to run the script & watch the magic.
#all converted MP3s will be placed in the same directory as the original WAVs.

JT5D / GDocService.cs
Created September 9, 2016 08:57 — forked from radiatoryang/GDocService.cs
Fetches a public Google Spreadsheet in Unity. (Doesn't work in Webplayer due to the security sandbox.)
// To prepare a Google Spreadsheet for this:
// make sure the spreadsheet has been published to web (FILE >> PUBLISH TO WEB), which is NOT the same as sharing to web
// To use in a different script:
// 1) include "using Google.GData.Client;"
// 2) include "using Google.GData.Spreadsheets;"
// 3) call "GDocService.GetSpreadsheet( string spreadsheetKey );", see DebugTest section for sample usage

JT5D / VRUtility.cs
Created September 9, 2016 08:56 — forked from radiatoryang/VRUtility.cs
a script I give to my Unity VR students that demonstrates a few useful "quality of VR" features for their games -- lowering visual quality for higher framerate, and HMD recentering
using UnityEngine;
using System.Collections;
using UnityEngine.VR; // you always need this to use special VR functions
public class VRUtility : MonoBehaviour {
// Use this for initialization
public void Start () {
// set render quality to 50%, sacrificing visual quality for higher FPS
