Separate favicons for the Frontend and Backend

Here's a nifty little idea I had that has some merit and is super easy. Separate favicons for separate areas of a site. Basically, I can't live without Firefox or Chrome and the way they use multiple tabs, having about 20-50 open at any one time.. But that makes it more difficult to find the right tab!

PHP fsockopen for FAST DNS lookups over UDP

While reading up on gethostbyaddr on PHP.net, I saw a nice idea for using fsockopen to connect over UDP port 53 to any Public DNS server, like Google DNS 8.8.8.8, and sending the reverse addr lookup in oh about 100 bytes, then getting the response in oh about 150 bytes! All in less than a second. This is how/why to read/write data directly to the wire! This would be extremely valuable for use in things like my online header tool because it's faster than any other method. As usual, I went a bit overboard optimizing it to be lean and fast.

Boosting Googles PageSpeed Module with TMPFS

Boosting Googles PageSpeed Module with TMPFSGoogle's mod_pagespeed speeds up your site and reduces page load time. This open-source Apache HTTP server module automatically applies web performance best practices to pages, and associated assets (CSS, JavaScript, images), all transparently like a Squid Proxy.

With TMPFS you can dramatically improve the speed of mod_pagespeed and the webpages served by it. TMPFS will store/serve the optimized PageSpeed output directly from RAM!

Get Number of Running Proccesses with PHP

Apache Httpd Number ProcessesRecently I had to setup a script to curl 10k urls, but it could only do 500 requests at any one time. In order to work under that limit, I created a function that returns the number of currently running processes on the machine in an extremely fast and efficient way, thus allowing the curl_multi requests to queu themselves such as GNU xargs.

MySQL Performance Tuning Scripts and Know-How

MySQL Performance Tuning Scripts and Know-HowUnless you are a total linux-freak-guru like myself, and even if you are, it can be enormously challenging and somewhat overwhelming to locate and eliminate MySQL bottlenecks. While many DBAs focus on improving the performance of the queries themselves, this post will focus on the highest-impact items: MySQL Server Performance and OS Performance for MySQL. Specifically showing 4 awesome tools to auto-tune your MySQL and a few more tools just for monitoring!

King Penguin Linux Notebook

King Penguin Linux Notebook The machine itself is super super ultra-thin, wafer thin, very cool looking. It's crazy light, I was amazed how slick it looked when it arrived.
Huge amount of open-source hardware/chipsets/etc.. The first time I went through the dmesg I was smiling. 2 USB 3.0 ports, and they actually work as promised, very very fast transfer speeds to my USB 3.0 external SSD. Incredible speed, boot time is the fastest I've ever seen. Starts at $720, mine was $1,800

The power of the Web is in its universality. Access by everyone regardless of disability is an essential aspect. -Tim Berners-Lee


A strong free software movement focused on the principled issues of software freedom and a strong FSF in particular will determine what freedoms the next generation of computer users enjoy. At stake is no less than the next generation's autonomy. -Benjamin Mako Hill

Hacking and Hackers

The use of "hacker" to mean "security breaker" is a confusion on the part of the mass media. We hackers refuse to recognize that meaning, and continue using the word to mean someone who loves to program, someone who enjoys playful cleverness, or the combination of the two. See my article, On Hacking.
-- Richard M. Stallman
