Programming Fonts for the Web

The idea is to use CSS to have the browser display programming and code similar to the high-quality look of a developers machine, like this older screenshot of my VIM.

Add CSS Class to body when Sidebar is Present

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.

Htaccess Rewrites – Rewrite Tricks and Tips

htaccess rewrite / Mod_Rewrite Tips and Tricks is as glamorous as it sounds! htaccess rewrite mod_rewrite is just possibly one of the most useful Apache modules and features. The ability to rewrite requests internally as well as externally is extremely powerful.

Adding YouTube Videos To Website, 4 Methods

This is the advanced example. It uses the jw flv player to create a flash proxy. This basically lets me control the youtube video as if it were a local .f4v file. With this method I can specify any options, autostart, volume, playlists, etc.. But it's rather complex so lets start with 3 other methods to embed YouTube video.

Creating an Offline Version of Page

I can do anythingSo, here's what I hacked together last night, that is being used today. It's essentially 2 files.

  1. A php file that scrapes uses curl to scrape all the urls for the page (favicon, css, images, pdfs, etc..)
  2. A simple bash shell script acting as a cgi that creates a zip file of all the urls, and a self-extracting exe file for those without a winzip tool

Ultimate Htaccess Part II

Editing an Apache .htaccess file in VIM. 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.

Actual Htaccess Files from My Server

#### No https except to wp-admin -
# If the request is empty ( implies fopen or normal file access by a php script )
RewriteCond %{THE_REQUEST} ^$ [OR]

# OR if the request if for wp-admin or wp-login.php
RewriteCond %{REQUEST_URI} ^/(wp-admin|wp-login\.php).*$ [NC,OR]

# OR if the Referer is https
RewriteCond %{HTTP_REFERER} ^https://www.askapache.com/.*$ [NC]

# THEN skip the following rule, basically all this does is force https or badhost to be redirected
# BUT because of the above 3 rewritecond's, this won't break poorly written admin scripts
RewriteRule .* - [S=1]

RewriteCond %{HTTPS} =on [OR]
RewriteCond %{HTTP_HOST} !^www\.askapache\.com$ [NC]
RewriteRule .* http://www.askapache.com%{REQUEST_URI} [R=301,L]

RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /(wp-admin/.*|wp-login\.php.*)\ HTTP/ [NC]
RewriteCond %{HTTPS} !=on
RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

Advanced WordPress wp-config.php Tweaks

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..

Firefox Add-ons for Web Developers

askapache favorite addonsAdvanced Web Development by AskApache is a Firefox Collection I created since I'm always trying new Addons out and using multiple computers and I wanted a quick and easy way to install my favorite's and keep a running list. Firebug, YSlow, LastPass, and Web Developer are the only ones I always use regularly.

I like the idea of the last.fm but it's not as powerful as the site, which is awesome. Lately listening to Kings of Leon Radio...

Optimizing Servers and Processes for Speed with ionice, nice, ulimit

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.

Protecting Files with Advanced Mod_Rewrite Anti-Hotlinking

If you have files on your site that you don't want indexed by malicious search engines, grabbed and leeched by malicious spammers, or stolen and made available elsewhere, you can use mod_rewrite to drastically reduce or totally reduce that activity.

mod_rewrite Fix for Caching Updated Files

Web Developers sometimes use file.ext?v=004 as a version control system to force visitors to use updated files. This is terrible. Instead link to apache-003.css and set it to be cached forever. When you change the file you just change the links to apache-004.css. That eliminates millions of bandwidth and resource robbing If-Modified-Since requests. You only need Apache with mod_rewrite, and 1-10 minutes!

The Right to Read

The proponents of this scheme have given it names such as "trusted computing" and "palladium". We call it "treacherous computing", because the effect is to make your computer obey companies instead of you. This was implemented in 2007 as part of Windows Vista; we expect Apple to do something similar. In this scheme, it is the manufacturer that keeps the secret code, but the FBI would have little trouble getting it.

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.
