Ball lightning

From "Ball lightning: the coolest thing you’ve never heard of":

Ball lightning looks like a floating glowing fuzzy ball of light, usually a few inches to a few feet in diameter. It floats or moves around rooms, airplanes, open areas – and occasionally through solid objects. It usually lasts for a few seconds or, rarely, minutes, and then disappears, silently, or with a popping sound, or sometimes even a loud explosion and a surge of electricity through nearby objects. This surge often sets on fire, blows up, or electrocutes nearby objects – everything from cows to VCR players to people. Ball lightning usually appears under in the same circumstances as regular old lightning: during major storms, flying through clouds in planes, etc.

Ball lightning is super cool!!

On becoming comfortable with privacy violations

From a post titled "I'll never bring my phone on an international flight again. Neither should you":

Over time, this unparalleled intrusion into your personal privacy may come to feel as routine as taking off your shoes and putting them on a conveyer belt.

"Six other times the US has banned immigrants"

From an Al Jazeera article:

...this is not the first time that the US has banned immigrants from its shores. Over the past 200 years, successive American presidents have placed restrictions on the immigration of certain groups.

Ashamed to say we're at it again.

Z-index seems so simple...

From "What No One Told You About Z-Index":

Z-index seems so simple: elements with a higher z-index are stacked in front of elements with a lower z-index, right? Well, actually, no. This is part of the problem with z-index. It appears so simple, so most developers don’t take the time to read the rules.

I love posts that delve deep into an obscure topic and explain it clearly, and this is a great one.

Prevent Homebrew from gathering analytics

Homebrew gathers anonymous analytics about its users. The Homebrew maintainers explain that they use the anonymous data to help the project, but you might want to disable this for two reasons:

  1. You don't want any of your data being shared at all.
  2. You want to avoid an unnecessary analytics network request.

You can disable Homebrew's analytics in one of two ways:

With a command:

brew analytics off

Or with an environment variable:


You can set this in your shell startup (your .bashrc, for example).

To see whether Homebrew is gathering data, you can run this command to print whether it's enabled:
