5 Why’s

Here is something new I learned today.  While reading the blog post on “Why You Need a Postmortem Process” over sysadvent (yes, it’s an advent calendar for system administrators, and it just started this year’s run),  I stumbled upon the 5 Whys Wikipedia page:

5 Whys is an iterative interrogative technique used to explore the cause-and-effect relationships underlying a particular problem. The primary goal of the technique is to determine the root cause of a defect or problem by repeating the question “Why?” Each answer forms the basis of the next question. The “5” in the name derives from an anecdotal observation on the number of iterations needed to resolve the problem.

What do I think of immediately? Louis CK bit on parenting and kids’ ability to ask an infinite number of “Why?” questions:

Well, I guess, kids, much like me until today, don’t know that you only need 5.  Or 6.

ASCII vs. ANSI

Browserling does it again:

ascii-ansi

For those of you not old enough, here are the ASCII and ANSI Wikipedia pages.  Back in a day we used these for cool art, fancy user interfaces, email signatures, games and more.  Have a look at some cool examples of ASCII art.  Now imagine those “images” colored with the breathtaking variety of 8 colors and you’ve got yourself a true 90’s rainbow explosion.

You’d probably be surprised to learn that a lot of these have survived to modern day, and are still used in command line user interfaces.

P.S.: And if you think that this stuff is ancient, have a look at typewriter art example.
