Mod_Security rivals Mod_Rewrite in the amount of features it provides. I decided to go ahead and post what I learned about it today, even though its tough to give away such awesome htaccess and apache tricks.. Learn how to control spam once and for all, conditionally log/deny/allow/redirect requests based on IP, username, etc.. Mod_Security is so fine!

SOPA: Anonymous Lists Their Demands
A rallying cry on the occassion of the Web's first mass blackout
As we watch the web go dark today in protest against the SOPA/PIPA censorship bills, let's take a moment and reflect on why this fight is so important. We may have learned that free speech is what makes America great, or instinctively resist attempts at silencing our voices. But these are abstract principles, divorced from the real world and our daily lives.
Free speech is the foundation of a free society. We can have the vote all we want. We can donate money wherever we want. But unless we're able to talk to each other and figure out collectively _what_ we want, those things don't matter.
We believe a healthy society doesn't allow its artists, musicians and other creators to starve. The copyright industry has been justly criticized for abusing the political process in a desperate attempt to maintain its role as a cultural gatekeeper, a business model made obsolete by a digital age of free copies. But the RIAA, MPAA & IFPI deserve our opprobrium for making enormous profits while often leaving the very artists it claims to represent *poorer* than they would be as independents.[1] While the public may have greater access to the few artists deemed sufficiently marketable to gain mass media promotion, fewer and fewer of us are making art and music in our own lives.
We call upon all freedom loving Internauts to join us. We further call upon our legislators, bureaucrats and the media & telecommunications industries to immediately begin implementing our demands. The future of free speech is bright, and clear - either stand with us or get out of the way.
PirateBay Press Release regarding SOPA...
So, the whole basis of this industry, that today is screaming about losing control over immaterial rights, is that they circumvented immaterial rights. They copied (or put in their terminology: "stole") other peoples creative works, without paying for it. They did it in order to make a huge profit. Today, they're all successful and most of the studios are on the Fortune 500 list of the richest companies in the world. Congratulations - it's all based on being able to re-use other peoples creative works. And today they hold the rights to what other people create. If you want to get something released, you have to abide to their rules. The ones they created after circumventing other peoples rules.
The reason they are always complainting about "pirates" today is simple. We've done what they did. We circumvented the rules they created and created our own. We crushed their monopoly by giving people something more efficient. We allow people to have direct communication between eachother, circumventing the profitable middle man, that in some cases take over 107% of the profits (yes, you pay to work for them). It's all based on the fact that we're competition. We've proven that their existance in their current form is no longer needed. We're just better than they are.

Well what can I say, other than this is sooo DOPE! Here is a list of the modules this plugin (version 4.7 unreleased) will automatically detect. I compiled the list myself using every module included with any default Apache installation for ALL the versions listed below, 1.3 to 2.2+
Want to know something else I'm including in this plugin? For each and every module that is detected, this plugin can then detect ALL of the modules .htaccess Directives! For instance, RewriteRule, AccessFileName, AddHandler, etc.. are each a directive belonging to a module that is allowed to be used from within .htaccess files.

To prepare for several upcoming articles on AskApache that are focused on optimizing Servers and Sites from a server admin level, here is an article to introduce the main tools that we will be using. These tools are used to optimize CPU time for each process using nice and renice, and other tools like ionice are used to optimize the Disk IO, or Disk speed / Disk traffic for each process. Then you can make sure your mysqld and httpd processes are always fast and prioritized.

NOT a typo.. 30x is measurable, well-documented, and easily tested. This is what open-source is about. I haven’t had time to post much the past year, I'm always working! So I wanted to make up for that by publishing an article on a topic that would blow your mind and be something that you could actually start using and really get some benefit out of it. This is one of those articles that the majority of web hosting companies would love to see in paperback, so they could burn it.

Since I was disqualified and accused of cheating, which is absolutely false, I decided to go ahead and do the crime I have been punished for. That's right, I'm going to show YOU how I could have rigged the DHSOTM contest to hopefully make the statement that I absolutely did not cheat and I absolutely want to be re-instated as the winner.

This is awesome. I was so fed up with trying to find a fail-proof, cross-platform way to find the mime type of an image using PHP that I wrote a quick function that utilizes the same technology as the exif_imagetype, getimagesize, and finfo functions do. Ahh the joys of low-level.

This is a big update from the last time I looked into this, when I enumerated 57 Status Codes that Apache 2.x was capable of handling. This list contains 83 Status Codes recognized by Apache. I compiled the latest 2.4.4 Apache in order to view the actual codes sent by a live server.. very cool. You can read about the newest HTTP Status Codes in RFC 6585.

I really really wanted to run the latest MariaDB with LZ4 Page Compression.. it is a game changer for many types of large databases I deal with. So I compiled it manually in a way that is repeatable and follows best-practices and it's now powering this site. Now I can use InnoDB Page Compression with lzo, lzma, bzip2, snappy, or my favorite algorithm: LZ4.

Thought this would be a good chance to post a howto, and show that there is a lot you can do by compiling software yourself and breaking the package management one-click install shackles.

The bottom line for this article is that I want to make WordPress as fast, secure, and easy to install, run, and manage because I am using it more and more for client production sites, I will work for days in order to solve an issue so that I never have to spend time on that issue again. Time is money in this industry and that is ultimately (time) what there is to gain by tweaking WordPress.
Note: I spent no time on readability, this is primarily a read the code and figure it out article.. This is for advanced users looking for a reference or discussion and for those of you looking to advance. Feedback would be great if you make it that far..
