We close our eyes

November 8

My journey of growth has been ascending levels of perspective shifts. Some of us don’t get to go on that journey because of external and evil forces or because of the random, initial conditions they drew at the beginning of their lives. While I don’t understand what my self even is, I do understand that hiding—ignoring reality—is not going to move me further along on my journey of self-discovery.

“Daytime” is us closing our eyes and pretending it makes infinity go away.

Munroe has gone on quite a journey. I think everyone far enough along on their needs-satisfaction curve (anyone who’s ever watched entertainment or played a video game is far enough along) would be moved, inspired, made to laugh and cry, by reading all of Munroe’s cartoons.

This cartoon is number 2,849. He publishes a cartoon Mondays, Wednesdays, and Fridays. So, he’s published cartoons for about 950 weeks. About 18 years.

Reality check: A public service announcement about passwords

February 20, 2020

If anyone ever says to you, “your password must contain one capital, a digit,…”, you can be certain that they are an idiot, and that they do not understand security. If you encounter such requirements in software, then it was written by an idiot—or it was written to a standard which was written by an idiot.

I’m serious. This is not hyperbole. Anyone who says such things truly has not even the most basic understanding of computer security. You should immediately stop trusting them with anything related to computer security.

To begin to understand why this is true, please enjoy this wonderfully explanatory cartoon from XKCD: Password Strength.

The cartoon is fun, but its core point about the critical feature of your passwords being the amount of entropy they contain will make you smarter than the vast majority of people.

Getting to space is easy. Staying in space is hard.

September 29, 2013

The reason it’s hard to get to orbit isn’t that space is high up. It’s hard to get to orbit because you have to go so fast.

…

The speed you need to stay in orbit is about 8 kilometers per second. Only a fraction of a rocket’s energy is used to lift up out of the atmosphere; the vast majority of it is used to gain orbital (sideways) speed.
