Reset Forgotten Raspberry Pi Password

Remove SD Card

The first step is to turn off the Raspberry so you can remove the memory card without worry.

If the Raspberry Pi is not connected to a screen, the only way to turn it off is to unplug it. Otherwise, you can go through the GUI to turn it off properly, via the menu, before unplugging it.

Once the Raspberry Pi is turned off, you can insert the card into your computer and go to the next step.

How to use

Login to https://web.telegram.org
Copy-paste contents of telegram-scripts.js into JS console
Run showContacts() to get the list of contacts with ids
Run saveChat(userId) where userId is the id from step 3

Process can take a while, check console for progress. Occasionall FLOOD_WAIT errors are expected. Once done, browser will download the JSON file.

Motivation

Use Python to:

send a plain text email
send an email with attachment
receive and filter emails according to some criteria

Deploying pypy on uwsgi

Instructions are kind of sporadic around the internet, so I thought I would gather them all in one place. The following example uses a Flask app as the thing deployed. You should only have to this once, and then you can pass the bin around.

Requirements

pypy 2.x (tested)
uwsgi 1.9.11+ (trunk as of this gist)

	import requests
	import json
	import sys
	import socket
	import time

	API_KEY = "***"

	# Instance requirements
	MIN_VRAM_MB = 80 * 1024 # 81 920 MB → covers full 80 GB cards

	# My steps to:
	# Convert DVD Video to MPEG-4 in MKV without GUI, using only CLI (Command Line Interface) tools.
	# No need for MeGUI, Avisynth, Handbrake etc..
	# ------------------------------------------------------------------------------

	# Tools needed: `mediainfo`, `ffmpeg` & `ffprobe`, `x264`, `mkvmerge`, `mplayer` (optional).
	# Google for them. Use latest versions. Windows tip: avoid Cygwin and get
	# the official builds, x64, when possible.

	# Before start use `mediainfo` & `ffprobe` and note down informations about the source material:

	if ($request_method = OPTIONS) {
	# Handle OPTIONS method
	add_header Content-Length 0;
	add_header Content-Type text/plain;
	return 204;
	}

	# Headers get added no matter the request method
	more_set_headers "Access-Control-Allow-Credentials: true";
	more_set_headers "Access-Control-Allow-Methods: GET, POST, PUT, DELETE";
