noln / created-date-from-filename.py

Last active November 15, 2025 18:49

Downloading videos from Google Photos in bulk results in the created date and last modified date being set to when the video was downloaded, not when it was created. This script takes a list of video files (as in the output of `ls -> files.txt` or suchlike), and if it recognises a timestamp in it, sets created date to that.

	#!/usr/bin/env python3
	"""
	update_file_times.py

	For every file in the current directory:
	* If the name matches the GoPro pattern GX??????_#############.MP4
	→ use the 13-digit millisecond epoch as the new timestamp.
	* If the name matches the Pixel pattern PXL_YYYYMMDD_HHMMSSsss*.mp4
	→ use YYYY-MM-DD HH:MM:SS.sss (milliseconds) as the new timestamp.
	* Otherwise the file is skipped.

A basic activity that listens to zen_mode state (Android's "do not disturb" volume/vibration muting feature) and dumps the current value to log. There are two ways included; the first is an observer and doesn't work in every case (I think there's a separate preference for priority messages), the second may is a manual check by hitting a button.

	import android.database.ContentObserver;
	import android.os.Bundle;
	import android.os.Handler;

noln / failoverScreenshot.java

Last active August 29, 2015 14:25

Using this instead of straight Spoon.screenshot(..) until issue identified in https://github.com/square/spoon/issues/151 is resolved. Extremely noddy for a Gist, but works with my library-builder script (which I might open source when it's done :-P).

	private void failoverScreenshot(String desc) {

	try {

	Spoon.screenshot(getActivity(), desc);
	}
	catch (IllegalArgumentException e) {

	Log.v(TAG, "Handled erroneous Spoon-Client screenshot exception.");
	}

	First-off, huge thanks both Fenix and Buffer teams for the apps, I use them both
	every day, and think they're brilliant! The only issue I have is that they don't
	currently like to talk to eachother...if they did? That would be great!

	Here's my analysis on why they currently don't:
