Rich Hickey on becoming a better developer

Rich Hickey • 3 years ago

Sorry, I have to disagree with the entire premise here.

A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.

Mastery comes from a combination of at least several of the following:

	{
	return arr.Skip(min).Take(max - min + 1).Max();

	{
	return arr.Skip(min).Take(max - min + 1).Min();
	}

	None of the above were helpful for me. I found I needed to clear the plugin method. In 5.6, I could do:

	sudo mysql -u root
	use mysql;
	[mysql] update user set plugin='' where User='root';
	[mysql] flush privileges;

	In 5.7, I found I needed to:

	private int match(double match_value, int min, int max, int match_type, ref double[] array)
	{
	switch (match_type)
	{
	case 1:
	{
	List<double> val_in_range = new List<double>();
	for (int i = min; i < max+1; ++i)
	{
	if (array[i] <= match_value)

	Productivity

	I think I am at least somewhat more productive than average, and people sometimes ask me for productivity tips. So I decided to just write them all down in one place.

	Compound growth gets discussed as a financial concept, but it works in careers as well, and it is magic. A small productivity gain, compounded over 50 years, is worth a lot. So it’s worth figuring out how to optimize productivity. If you get 10% more done and 1% better every day compared to someone else, the compounded difference is massive.
