On the Quest for Blazing Performance – NginX, DNS, and caching (Part 1)
(Date: 8/21/2008) As you may know, I am eminently concerned with ad delivery (here: economics of ad delivery), and as part of that, have recently embarked on a quest for blazing and blistering web performance out of my webservers. After all, more pages delivered (= more ads) & more returning visitors (= more ads). When most people think of optimizing their server... Read more →
Economics of Ad Delivery
I would like to talk a little bit about the economics of ad (as in web advertising unit) delivery. Not because I am the biggest expert in the world, but because I have been wrongheaded about the issue in the past.

HTML Strip of comments, whitespace and crap
As you develop your super-high-power web site, you may find that over the years pages become saturated with comments and formatting whitespace, designed to improve your personal readability.

I’m sure you know about them — they are the components to the system that give your dynamic web site blazing speed. Examples are Varnish, Squid, Google ncache, and mod_cache. But I would submit to you, my anticipatory readers... Read more →
I hate Linux
So, after having been asked one too many times “why don’t you run Linux on that machine?”, and suffered the subsequent explosion at my friends and neural breakdown: “well why don’t you run your car into a brick wall!!” I yell back in some nonsequitious malformed insult that isn’t even marginally analogous. You see, I use Windows, which I say neither proudly,... Read more →
One Keyboard to rule them all (Reviews)
Since I’ve become what can only be d3scr1b3d as an ultrahacker (I can break encryption keys in 12 languages, I go by the hacker alias N3O, and apparently help my landlady take out the trash. One of these lives has a future… the other does not.), I’ve decided to upgrade my computing center to the mega-ultra-command complex of usability that it deserves.... Read more →
