"The greatest performance improvement of all is when a system goes from not-working to working"

From a lecture by Professor John Ousterhout at Stanford.

Programmers tend to worry too much and too soon about performance. Many college-level Computer Science classes focus on fancy algorithms to improve performance, but in real life performance rarely matters. Most real-world programs run plenty fast enough on today's machines without any particular attention to performance. The real challenges are getting programs completed quickly, ensuring their quality, and managing the complexity of large applications. Thus the primary design criterion for software should be simplicity, not speed.

> Occasionally there will be parts of a program where performance matters, but you probably won't be able to predict where the performance issues will occur. If you try to optimize the performance of an application during the initial construction you will add complexity that will impact the timely delivery and quality o

"Scar Tissues Make Relationships Wear Out"

04/26/2103. From a lecture by Professor John Ousterhout at Stanford, class CS142.

This is my most touchy-feely thought for the weekend. Here’s the basic idea: It’s really hard to build relationships that last for a long time. If you haven’t discovered this, you will discover this sooner or later. And it's hard both for personal relationships and for business relationships. And to me, it's pretty amazing that two people can stay married for 25 years without killing each other.

[Laughter]

> But honestly, most professional relationships don't last anywhere near that long. The best bands always seem to break up after 2 or 3 years. And business partnerships fall apart, and there's all these problems in these relationships that just don't last. So, why is that? Well, in my view, it’s relationships don't fail because there some single catastrophic event to destroy them, although often there is a single catastrophic event around the the end of the relation

OBSOLETE

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.

	var reverse = function(str) {
	var ans = [],
	arr = str.split('');
	arr.forEach(function(chr) {
	ans.unshift(chr);
	});
	return ans.join('');
	};

	set dFolder to "~/Desktop/screencapture/"

	do shell script ("mkdir -p " & dFolder)

	set i to 0
	repeat 960 times
	do shell script ("screencapture " & dFolder & "frame-" & i & ".png")
	delay 30 -- Wait for 30 seconds.
	set i to i + 1
	end repeat
