adoyle / organize_by_year_month.sh

Created March 25, 2025 14:52

Using the file date, move the file into a directory named YEAR-MON. The directory is created if it doesn't exist.

	#/usr/local/bin/bash

	DST_DIR=~/Photos/exports

	# Organizes files by year/month into the DST_DIR
	find . -type f \| \
	while read i; \
	do IFS=' ' read -r -a result <<< $(ls -lUTD %Y-%m "$i");\
	mkdir -p $DST_DIR/${result[5]};\
	mv "$i" $DST_DIR/${result[5]};\

adoyle / fixup_image_timestamps.sh

Created March 25, 2025 13:26

Quick hack to fix file timestamps on image files that are exported by Apple Photos.

	#/usr/local/bin/bash

	# Sets file modification time to the same as the creation time
	find . -type f \| \
	while read i; \
	do IFS=' ' read -r -a result <<< $(ls -lUTD %Y%m%d%H%M.%S "$i");\
	touch -t ${result[5]} "$i";\
	done

adoyle / mailip.py

Created October 23, 2015 18:26

Meant to be run on a Raspberry Pi to email the current IP address to yourself. Note that this uses unauthenticated SMTP and only works in certain circumstances. This lets you run a headless pi that you can ssh in to.

	import smtplib
	import subprocess

	my_email = '[email protected]'
	to_email = '[email protected]'

	myip = subprocess.check_output(['hostname', '-I'])

	msg = ("From: %s\r\nTo: %s\r\nSubject: %s\r\n\r\n") % (my_email, to_email, "IP from the Pi")

Non-interactive command-line equivalents to raspi-config

	# Non-interactive command-line equivalents to raspi-config
	# These are not guaranteed to work under all circumstances.
	# I use them in a fabric script to do unattended setup of a
	# Raspberry Pi immediately after having booted up a NOOBS
	# and installed Raspbian.
	#
	# 1. Install NOOBS
	# 2. When the config screen comes up, hit TAB TAB RETURN to exit from it
	# 3. Type 'sudo service ssh start' at the command line (no quotes).
	# 4. (Optional) copy a public key to the pi account on the pi.

serves up foo.html and provides simple tests of motor control

	from flask import Flask, render_template, request

	import RPi.GPIO as GPIO

	# initialize serial port
	port = serial.Serial("/dev/ttyAMA0", baudrate=19200, timeout=3.0)

	# wait 2 seconds

Snippet to send motor controller requests via jQuery get()

	// lock keeps requests from piling on top of each other.
	// without this, you can get requests totally out of order

	var lock = 0;
	function mouseMove(event) {
	var speed = event.pageY / 4; // Just a hack to make the control box bigger
	if ( lock === 0 ) {
	lock = 1;
	$.get('/motors?m1s=' + speed + '&m2s=' + speed +'&m3s=' + speed,
	function(data) {
