8G Firewall Addon: Protect Against Rogue PHP File Attacks

Been getting hit with massive attacks on all sites. Very large VPN/proxy network. Relentless requests 24/7, thousands of requests every minute, just non-stop attacks. All URL requests targeting rogue PHP files. The attacks were weighing on precious server resources. Server held up fine but this nonsense needed to stop. So I wrote a tight little addon for my 8G Firewall. Blocks the entire attack with just a few clicks.. Continue reading »

What Those Three Linux “CPU Usage” Numbers Mean

Just a quick note to self (and anyone looking for the same information). A common question I get for my free WordPress plugin, Dashboard Widgets Suite (DWS), is “what do the CPU Usage” numbers mean? Users get curious because the DWS plugin displays something like this on the WordPress Dashboard: Displaying CPU Usage and other stats on the WP Dashboard (click image for full-size view) Notice in the screenshot, where it shows the three numbers for “CPU Usage”: 0.75, 0.55, […] Continue reading »

Get Yourself Some Backup Internet Service Providers

As a full-time web developer and typical human being, I rely on the Internet for a great many things. So when the Internet is not available, my work (and play) comes to a grinding halt. Fortunately my primary ISP is pretty solid, but it still goes down every once in a while. So to maintain my workflow (and general sanity), having a backup Internet service provider is absolutely essential. Here’s one way to do it.. Continue reading »

Online Tools for Traceroute & Ping

Traceroute not working correctly via macOS Terminal app, which is how I’ve been doing it for years now. For some reason, the traces hang up and never complete for certain sites. After some time troubleshooting and not finding any solution, I decided to look for alternate ways of performing traceroutes and site pings. Fortunately there are tons of free tools. Here are some of the useful services and apps that I’ve found.. Continue reading »

WordPress pre_get_posts + Combined Category Archives

This is a quick post following from the latest redesign of my WordPress plugins website, Plugin Planet. There, I make use of WordPress great query functionality to display archives of multiple categories. For example, here is the combined archive for BBQ Pro and Docs. So that category archive displays all documentation posts for BBQ Pro. Likewise for other categories, for example here is the combined archive for Banhammer Pro and Tutorials. That category archive displays all tutorial posts for Banhammer […] Continue reading »

Heavy Scans for Low-Hanging Fruit

I’ve been working on developing the 8G Firewall. Digging through log files and crunching the data, the big new trend I’m noticing is heavy scanning for easy targets, low hanging fruit. Bad actors are looking for any little hidden files stashed on your server. Mostly PHP files, also ZIP and RAR files, and other file formats commonly used for compressing and archiving content. Basically, anything that might contain useful information (like login credentials, database backups, email addresses, etc.). Also, 99% […] Continue reading »

BBQ Firewall – Count Blocked Requests

BBQ Firewall is built to be powerful, lightweight, fast and flexible. It’s code base is kept super lean, leaving extra functionality out of core while supporting new features via simple addons. For example, this tutorial shows how to use an addon to display the total number of blocked HTTP requests on the plugin settings page. This can help you get a basic idea of the plugin’s effectiveness. Continue reading »

Block Random String Comment Spam

Recently WordPress sites have been getting hammered with random-string comment spam. The attackers are clever, using random text strings for every vector except the payload, which usually is the URL used for the comment’s Name link. But for these weird comment spams, the apparent payload is the email address. It’s the only part of the comment that’s not made up of random gibberish. Continue reading »

HTML Abbreviations Cheat Sheet

Here is my custom list of abbreviations for commonly used terms, as written via HTML’s <abbr></abbr> tag. I’m posting this to make it available to anyone who finds it useful. Very handy when writing tutorials related to WordPress, web design and development. A quick copy/paste is much quicker than typing it all out. Without further ado, here is my “cheat sheet” of HTML abbreviations. Continue reading »

All CSS Filter Functions + Quick Copy/Paste Examples

CSS makes it easy to customize image appearance on the fly. So you don’t have to crank open your image editor and do any work there. You can apply many visual effects directly on the image using the CSS filter property. You can change image brightness, contrast, opacity, saturation — even do things like rotate hues, drop shadows, and blur the image. Browser support is solid for all major browsers.

Domain-Based, Site Specific Email Addresses FTW

I use domain-based emails for 99% of my email activity. The other 1% is comprised of assorted 3rd-party email services and temporary slash disposable addresses (like for testing purposes and one-off sign-ups, etc.). I can tell you whole-heartedly based on 20+ years working online that domain-based email is THE WAY to go. Continue reading »

DIY Server Uptime Monitor

There are many free (and commercial) uptime monitoring services that will alert you if your server goes offline. These services are popular because it’s mission critical to know when your sites are down. The sooner you know about it, the sooner you can scramble to get everything back online. I’ve tried other scripts and services but nothing that met my specific needs: simple, secure, lightweight and blazing fast. So decided roll my own DIY server status monitor and share it […] Continue reading »

Margin Offset for Anchor Targets with CSS or JavaScript

For sites using a fixed-position “sticky” header or similar, it’s necessary to add an offset margin to any on-page anchor targets. For example this recent article provides a Table of Contents menu with links to each section on the page. Click a link and the page scrolls down to the target element, which is an <h2></h2> heading tag. Thanks to one of the CSS solutions provided in this tutorial, the scrolling takes into account the page’s 50-pixel sticky header, so […] Continue reading »
