Optimized Vimrc with 256 Colorscheme

askapachecode 256color colorscheme and vimrc screenshotThis is not your everyday vimrc. This is my personalized vimrc.. works especially great on remote servers, in tmux, screen, etc.

This doesn't require a git checkout, a vim update, a bash update, an OS update, a plugin. No. 1 vimrc, 1 colorscheme, just use curl to download and it's on. I use this on Arch Linux, NetBSD, FreeBSD, OpenBSD, Debian, Ubuntu, Cent OS, Red Hat, and that's mostly it so far.
If you aren't already using vim as your primary editor in a powerful way, you are gonna owe me for this.

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!

Windows Optimization – Intense Part II

If you ever wanted to know the best way to defragment and speed up your Windows-Based PC, I mean you really wanted to know, here is the 2nd part to my article on Windows Speed Optimizing that details the process I have found works really well. Definately not a quick process, and certainly not the best ever, just my best ever and one that you only have to do once to get the benefits. This article has a lot of incredibly useful (and FREE) tools I recommend, which you can grab and use without reading the article..

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.

Vetted – Top 3 WordPress Speed Plugins

There are so many WordPress plugins out there now that I wanted to post my favorite 3 plugins for speeding up a WP-Powered blog. These are the 3 plugins that I install for pretty much all of my WP-Powered sites, which I run about 300 now. They work together to provide a very optimized blog for speed.

DB-Cache Reloaded does something entirely different, it saves the mysql queries that are made to the WP-database, as well as the mysql results to static files, and then through php serves those cached-files instead of re-querying the mysql database. Most mysql databases are stored on separate servers, and although many are on the same local network there is a limit to how many queries, and how many connections can take place.

So DB-Cache Reloaded basically makes WP-Super Cache work alot faster when generating the cache files, and DB-Cache Reloaded helps in a number of areas un-related to WP-Super Cache, like in the admin panel. And DB-Cache without WP-Super-Cache is a joke because it still uses the application-level and php for everything. Gotta use both (or just WPSC).

Get the Most from Search Engines

One of the most cost-effective ways to drive traffic to your Web site is to optimize it for search engines. Many of them use automated programs called "crawlers" or "spiders" to create an index of the Web, which they use to determine what sites are most relevant to users' queries. These programs essentially visit Web sites, read the pages' content, and follow any links to other pages, repeating the process

TMUX

penguin-tmuxarchlinux-on-macStop 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.

Install multiple OS Without Cds

Crazy POWERFUL Bash Prompt

bash power prompt PS1This amazing bash linux prompt does more than meets the eye. If you want to know how to become really good with technology, linux is the secret sauce behind the AskApache articles. Open Source is elixir of the web. Thanks to everyone who helped me for the past 20 years. I use linux/bsd because homey don't play, so this is geared to be as productive a prompt as I can make it.

Don't have much time.. or just don't care? Not a problem, here are the 3 lines to copy and paste - you can just paste them right in your shell to test it, or add to a startup script.

Preload flash .flv files into browser cache

How I was able to preload many flash flv and swf files on one of my clients sites that has a lot of online video and relatively small traffic. Their site visitors would usually watch 3-10 videos per visit and so to make the videos load almost instantly on every page I came up with a way to preload the top 10 .flv files and the swf flv player files as soon as the visitor successfully started watching the 1st video. Of course I also setup .htaccess caching on the server so that once they downloaded the files into their cache they would never request them from the server again. I was having fun with this so its pretty funky and uses some really cool combinations of javascript, swf preloader from xml, css classes to help automate it all..
