So, here's what I hacked together last night, that is being used today. It's essentially 2 files.
Server and Environment Variables are used by The Apache HTTP Server by provides a mechanism for storing information. This information can be used to control various operations such as logging or access control.
Web Professionals use mod_rewrite to issue 301 and 302 Redirects for Search Engines. Sometimes you may not have mod_rewrite.c or you want an alternative redirect method. Using mod_alias RedirectMatch you can use REGEX in Redirect commands!
Webmasters often use SSH to remotely admin web sites and servers, learn how to make your shell colorful and powerful using my sample .bash_profile and you can be up and running in 30 seconds!
Some of my favorite htaccess examples from some of my favorite .htaccess tutorials. These cut-and-paste ready htaccess code snippets are very useful for website and server administrators.
Oh ya lets get it on! short but sweet

I am often logged in to my servers via SSH, and I need to download a file like a WordPress plugin. I've noticed many sites now employ a means of blocking robots like wget from accessing their files. Most of the time they use .htaccess to do this. So a permanent workaround has wget mimick a normal browser.
strace+ is an improved version of strace that collects stack traces associated with each system call. Since system calls require an expensive user-kernel context switch, they are often sources of performance bottlenecks. strace+ allows programmers to do more detailed system call profiling and determine, say, which call sites led to costly syscalls and thus have potential for optimization.
Securing Subdirectories using unique apache htaccess solutions.
Time-dependant rewriting uses mod_rewrite and apache server time variables to display different files depending on the time, while the URL stays the same. An often requested implementation of this is to display a different home page or image depending on if its morning, noon, or night.
After I optimized the caching for my non-dynamic pages using apache modules mod_headers and mod_expires, I began to learn about phpbb seo..
Well, not this sites server, which has never been hacked, but a server hosted with hostgator.
Interestingly, the hacker sent me an email and left me an mp3, which I've uploaded for your listening leisure.
Do real hackers exist? Yes. Can we coexist? Preferably!
By removing the ETag header, you disable caches and browsers from being able to validate files, so they are forced to rely on your Cache-Control and Expires header.
If you remove the Last-Modified and ETag header, you will totally eliminate If-Modified-Since and If-None-Match requests and their 304 Not Modified Responses.
If you use Apache to auto-generate directory index listings of files/dirs, and you have a large number of files and directories in the root directory and/or slow IO speed, then generating the index could take Apache over a minute!
Stop wasting your lives with Mac Terminals.. or Macs. Get a real machine and then get a real shell multiplexer! For many years we all loved GNU Screen, but tmux is by far a better option today. The only time I am in the shell and not using a multiplexer, is when I'm not on one of my machines. My Arch Linux machines all run URxvt and my .bash_profiles all start tmux automataically, whether in X or single-user mode, tmux is where it's at.
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?
Ever wanted to execute commands on your server through php? Now you can. I'm calling this file (see below) shell.php and it allows you to run commands on your web server with the same permissions that your php executable has.
The Admin Bar in WordPress is always shown when in the backend administration area no matter what.
You are given the option to show/hide the admin bar when viewing the site, but there is no option to show/hide the admin bar when using the backend... So I created a plugin to provide that option on profile pages.
Why hide the admin bar in backend?
Normally I like the admin-bar and usually have it enabled, but it's nice to be able to switch it on/off from the "Edit Profile" page. The biggest reason for not loading/showing the admin_bar in the backend is SPEED. Here are 2 instances where I hide it-
· Sites with many authors/admins
· Moderating Comments on a Mobile Phone
WordPress blogs show the same duplicate content for https://www.askapache.com/index.php and https://www.askapache.com/. If you've read about using a robots.txt file for WordPress SEO, than you already understand this setup results in Duplicate Content penalties being levied against your Blog and Web Site by Search Engines.

Here's the problem I was having while working on a custom theme for a client. Certain pages, posts, tag pages, archive pages, and custom pages either had the sidebar, or did not have the sidebar. The main content div #ContentW had a 72% width when the sidebar was present, otherwise it was 96%. The problem was that I dislike having to do things manually when they can be automated through code. What I was having to do was manually add/remove page-specific classes to the css file to reflect whether the sidebar was present on that page or not.

I've tried 100's of Anti-virus, Anti-Rootkit, and Anti-Spyware tools over the last 10 years, but it's always good to re-examine your system's security every couple of months.
A pure bash alternative to the python reflector, using curl, xargs, and sort for ranking Arch Linux mirrors.
Nice and simple. Short and sweet.
Scan Apache logs for IP address that are probably evil, then generates an .htaccess file to DENY them all.
If you have a php.cgi or php.ini file in your /cgi-bin/ directory or other pub directory, try requesting them from your web browser. If your php.ini shows up or worse you are able to execute your php cgi, you'll need to secure it ASAP. This shows several ways to secure these files, and other interpreters like perl, fastCGI, bash, csh, etc.
Apache .htaccess and httpd.conf have the power to send and manipulate HTTP Header Requests like sending P3P privacy headers, Content-Type: UTF-8, Content-Language, etc. The power is immense and you can do some really cool stuff with HTTP Headers!
