Custom Headers with Simple Download Counter WordPress Plugin

Quick tip for my free WordPress plugin, Simple Download Counter. SDC is optimized for successful downloads in most server environments, but there always is an exception to the rule. For example, on some servers, a download’s content-length header may be calculated incorrectly for GZIP and possibly other file formats. This tutorial explains how to define your own headers for downloads when using Simple Download Counter, so you can dial in perfect downloads for any server configuration. Continue reading »

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 »

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 »

WordPress pre_get_posts + Combined Category Archives

This is a quick post following from the latest redesign of my WordPress plugins website, Plugin Planet.

That category archive displays all tutorial posts for Banhammer […] 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 »

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 »

WordPress get_comments_number() Not Working Correctly?

It seems that the WordPress function, get_comments_number(), is not working correctly. It is returning inconsistent results for posts with zero comments, pingbacks, or trackbacks. Sometimes the function returns true, other times false. It’s just random, from what I’ve been able to tell. So maybe a bug, or maybe something I am missing. Not a big deal, just looking for clues..

WordPress: Display Posts on a Page with Paging and Navigation

In WordPress themes and plugins, the Loop is used to display posts on the front end. Typically the Loop displays either a single post (like when you’re viewing a blog post), or multiple posts (like when you’re viewing a category archive). Things get more tricky however, when you want to display posts on a page. Continue reading »

Target User Agents and Reduce Spam via robots.txt

Bad robots

Your website’s robots.txt file probably contains some rules that tell compliant search engines and other bots which pages they can visit, and which are not allowed, etc. In most of the robots.txt files that I’ve looked at, all of the Allow and Disallow rules are applied to all user agents. This is done with the wildcard operator, which is written as an asterisk *, like this: User-agent: * This site’s robots.txt file provides a typical example. All of the allow/disallow […] Continue reading »

Roll Your Own Simple Password Manager on macOS

Password Manager

I’ve tried 1Password and Dashlane, and several other popular password managers for both Mac and PC. It always seems to be the same thing: things start off great and then go downhill from there. For example, I was loving 1Password, and then it locked me out of my password file/account. Likewise for a couple of years Dashlane was great, but then they started making drastic changes like moving from standalone app to browser extension Web-based UI. The confusion involved with […] Continue reading »
