I'm Loyal to Nothing Except the Dream

Mon, 30 Jan 2017 09:19:56 GMT

There is much I take for granted in my life, and the normal functioning of American government is one of those things. In my 46 years, I've lived under nine different presidents. The first I remember is Carter. I've voted in every presidential election since 1992, but I do not

An Inferno on the Head of a Pin

Tue, 17 Jan 2017 11:37:18 GMT

Today's processors contain billions of heat-generating transistors in an ever shrinking space. The power budget might go from:

  • 1000 watts on a specialized server
  • 100 watts on desktops
  • 30 watts on laptops
  • 5 watts on tablets
  • 1 or 2 watts on a phone
  • 100 milliwatts on an embedded system


Let's Encrypt Everything

I've had something of an obsession with digital pinball for years now. That recently culminated in me buying a Virtuapin Mini.


OK, yes, it's an extravagance. There's no question. But in my defense, it is a minor extravagance relative to a real pinball machine.


The mini is much smaller than

Can Software Make You Less Racist?

Thu, 25 Aug 2016 07:52:37 GMT

I don't think we computer geeks appreciate how profoundly the rise of the smartphone, and Facebook, has changed the Internet audience. It's something that really only happened in the last five years, as smartphones and data plans dropped radically in price and became accessible – and addictive – to huge

Is Your Computer Stable?

Sun, 14 Feb 2016 06:58:39 GMT

Over the last twenty years, I've probably built around a hundred computers. It's not very difficult, and in fact, it's gotten a whole lot easier over the years as computers become more highly integrated. Consider what it would take to build something very modern like the Scooter Computer:

The Scooter Computer

Wed, 03 Feb 2016 08:52:36 GMT

When we initially deployed our handbuilt colocated servers for Discourse in 2013, I needed a way to provide an isolated VPN channel in for secure remote access and troubleshooting. Rather than dedicate a whole server to this task, I purchased the inexpensive, open source firmware friendly Asus RT-N16 router, flashed

Zopfli Optimization: Literally Free Bandwidth

Sat, 02 Jan 2016 09:38:24 GMT

In 2007 I wrote about using PNGout to produce amazingly small PNG images. I still refer to this topic frequently, as seven years later, the average PNG I encounter on the Internet is very unlikely to be optimized.

For example, consider this recent Perry Bible Fellowship cartoon.
