6G Firewall Beta
Since releasing the 5G Blacklist earlier this year, malicious server scans and bad requests have surged with more novel attacks than I’ve seen since first getting into this stuff six years ago. In other words, now is the time to beef up security and lock things down. If you’re into monitoring your server and knowing your traffic, you may be observing the same recent spike in malicious activity. In response to these attacks, I’ve been secretly working on the next […] Continue reading »

Blank Space / Whitespace Character for .htaccess
Working on the next version of the G-Series Blacklist, I needed a way to match a wide variety of UTF-8-encoded (hex) character strings. Those familiar with their site’s traffic will recognize this particular type of URI request string, which is typically associated with malicious server scanning, exploits, and other malicious behavior. As I explain in this post, pattern-matching and blocking the blank-space, or whitespace character in URL-requests is an effective way to improve the security of your website. Continue reading »

Ill requests and malicious scans have been spiking recently, to the point where server performance was really taking a hit.

Redirect WordPress Date Archives with .htaccess
Restructuring a WordPress website may involve removing the subdomain from URLs/permalinks. For example, I recently removed the original WP-install subdirectory from Perishable Press to simplify site structure and optimize WordPress permalinks. There are PHP scripts and WP plugins that might work for this, but in most cases .htaccess is optimal when changing URL structure and redirecting traffic. Here’s a quick example to help visualize the concept: Continue reading »
Dynamic Go-to-Top Link
Instead of displaying a perpetual “go to top” link for every page, here’s a quick way to dynamically display the link only if the content height is greater than that of the browser window.

PayPal Phishing Spam
Just a heads up to anyone else getting the occasional PayPal phishing spam.. Usually it’s pretty easy to spot one of those crafty phishing emails, just hover over any links before clicking to view the real URL in the status bar. You know, the link says something like, “click here to restore your PayPal account,” but you know that’s garbage and could easily prove it by checking the actual link URL, which is usually something completely bonkers, like: Continue reading »

Roll Your Own “What’s My IP Address?” Page
My current ISP likes to keeps things spicy by changing my IP address every few months or so. There are a million ways to get this changing IP information, but as an obsessive web developer, I like to roll my own whenever possible. That means using my own resources instead of spending time and energy elsewhere. So the goal for this project is to create a web page that does one thing very well: display the visitor’s current IP information. […] Continue reading »

Huge Collection of Code Snippets: HTAccess, PHP, WordPress, jQuery, HTML, CSS
Please excuse this self-serving, miscellaneous post, but I’ve just got to purge all of these code snippets and scraps collected over the years. Whenever I update this site, I place any removed/unused code snippets into a giant note file for future reference, just in case. There’s all sorts of different types of code and snippets that just keep growing and growing and.. and finally it gets to a point where I just need to dump everything and start fresh.
