Timestamping with mpv

Background

I did some usability testing and wanted to measure performance. We did a recording where the participants were solving the tasks.

And I wanted a quick and easy way to note down the beginning and end of a task. I needed these value pairs (like 300.52, 313.4, as the seconds since the start of the video) to do some computation with them.

Solution

Migrate neorg files to orgmode files

I wanted to switch from nvim-neorg to emacs orgmode. The major hurdle for switching was not setting up orgmode, but migrating my thousands of files that I still had in the .norg format.

The script contained here is what I used to migrate all of my files at scale. In the test files you can see how different features will be transformed by the script. Enjoy.

	// Return an array of numbers for specified range
	function range( min, max ) {
	min -= 2;
	return Array.from( new Array( max - min - 1 ), ( x,i ) => i - min );
	}

	// Return a random number from specified range
	const randomNum = ( min, max ) => Math.floor( ( Math.random() * max ) + min );

	// Get width of window

	var pad = function(num, totalChars) {
	var pad = '0';
	num = num + '';
	while (num.length < totalChars) {
	num = pad + num;
	}
	return num;
	};

	// Ratio is between 0 and 1
