I am almost ready to publish the final tutorial on using ssh tunnels from a truecrypt partition on a Windows machine. Of course I choose to go way overboard in my research and the tutorial is full of some pretty awesome windows tricks.. I will come back to this post soon and post all the other advanced tools I use for debugging windows, for now though you MUST know how to debug the kernel and use these basic debugging tools.
Unless 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!
PHP's fsockopen function lets you open an Internet or Unix domain socket connection for connecting to a resource, and is one of the most powerful functions available in the php language.
Here is even more information from the Ultimate Htaccess Part I. For now this is very rough and you will want to come back later to read it.
An image and technicacl achievement so profound, it will touch yoour heart.. So 3D... it'll hurt you eyes! LOL.. lol.. Man I am cracking up here. haha Ha definately the best intro ever, those really do look 3D for terminal though huh.. Sweet. Here is the little function I wrote to output that grey marble.
A list of API Versions and the corresponding HTTPD Version, for use in determining the version of Apache currently running without having to rely on the often inaccurate
Bash Functions and Aliases for Traps, Kills, and Signals. Useful for translating signal numbers/signal names and getting more info about signals.
AskApache Password Protect adds some serious password protection to your WordPress Blog. Not only does it protect your wp-admin directory, but also your wp-includes, wp-content, plugins, etc. plugins as well. Imagine a HUGE brick wall protecting your frail .php scripts from the endless attacks of automated web robots and password-guessing exploit-serving scripts.
Here is the basic process that I use to speed up Windows. A lot of good tips and tricks I've picked up over the past 15+ years of crashing and burning Windows that can transform your PC to be much faster than its ever been. The process focuses on freeing up RAM/Memory, freeing up your CPU/Processor, and optimizing your Hard Drive for a permanent solution.
Make sure to check out the free software I recommend at the end, installing them after this optimization process will keep your machine fast for a long time.
List of the directives available to Powweb users for use in htaccess files
Just a very brief look at speeding up form submission by delegating the processing and bandwidth to your server, not your client.
The story behind this plugin is sorta wack, but in a good way :). While doing tons of security research on permissions, authorization, access, etc.. for the Password Protection plugin (still being worked on), I needed to have unheard of debugging capabilities while working on the plugin on the various websites, webhosts, and test servers that I use to test in different environments. So I hacked together a bunch of php code that helped me debug, actually I pretty much went overkill and tried to get as much debugging info as programmatically possible, and it ended up being so much code that I took it out of my Password Protection code and made it its own plugin.
This article shows how to save and modify php session data, cookies, do anything really... without using ajax or iframes or forcing the user make a request.

The following is just a quick but detailed reference of some of the commands I used to successfully uninstall cpanel permanently. This is for advanced users of the shell. If you run a single one of these commands without fully understanding it, you will probably kill your server, lose everything on it permanently, not have a website or email for weeks.. So backup everything. FIRST. You should also contact your hosting provider support - but be prepared for some MAJOR negativity.. cpanel makes things very easy for web-hosting companies, and you are less than a drop in their bucket.
If for some reason you need to use windows .bat batch file scripting to do some task, or you just want to learn the most universal batch programming language on Windows machines, you lucked out and found the AskApache example. My expertise is the shell, in this article the shell is Windows
cmd.exe. It has some pretty advanced windows shell usage, including pipes and redirection, but it's the modular linux-like coding approach that earns this script it's "advanced" title.
set PROMPT=$_[%USERNAME%@%USERDOMAIN%]$S[$P]$_$M$G && EXIT /B
My favorite tool (and I've tried sooo many) for editing most Windows files and especially .bat files is the free and open-source Notepad++. Set that up and you will have a color-syntax-highlighted editor for Batch Scripting that works very very well.
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.
Talk about sick.. these tricks have the diamond disease!
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..
There are a total of 57 HTTP Status Codes recognized by the Apache Web Server. Wouldn't you like to see what all those headers and their output, ErrorDocuments look like?
- When php run as Apache Module (mod_php)
- When php run as CGI
- When cgi?d php is run with wrapper (for FastCGI)
Some good examples for how to use the Files and FilesMatch directives in .htaccess files and httpd.conf files for Apache.
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.
