TinyOLC - smallest Open Location Code implementation in JS
View olc.js
* TinyOLC - Open Location Code for smallest applications
* Differences from Google's open-source JS implementation:
* - less than 600 bytes minified (as opposed to over 4.5 KB from Google)
* - only 2 methods exposed - encode (lat, lng => str) and decode (str => [lat, lng])
* - only floating point degrees accepted as encoding input (positive as N and E, negative as S and W)
* - no short code resolution
* - no area encoding, only points with 11-digit resolution
* - assuming the block lower left corner only when decoding a low-res code
* - no validation checks

MTK Bootseq: enter alternative boot modes in MediaTek-based smartphones
#!/usr/bin/env python3
# Simple script to enter the necessary boot mode in the MT6572-based (etc) phones
# Depends on pyserial, otherwise fully cross-platform
# Usage: python3 [MODECMD] [port]
# e.g. python3 FASTBOOT /dev/tty.usbmodem14200
# and then connect the cable and repeatedly short-press the power on key
# Supported commands depend on the device and its preloader. Here's the list for Sigma S3500 sKai:
