Examples of Email Phishing in 2024

I enjoy sharing the pathetic phishing emails that make it past my spam filters. After watching various waves of phishing campaigns come and go over the past 20 years, I have come to accept that it’s just a part of life on the Web. Phishing scams have been happening since the dawn of the Internet, with no signs of stopping anytime soon. About the best you can do is practice safe email handling practices and never open any links or […] 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 »

Self-Hosted, Domain-Based 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 self-hosted email is THE WAY to go. Continue reading »

New WordPress Plugin: Simple Login Notification

New WordPress plugin! Simple Login Notification does one thing and does it well: sends an email alert whenever an admin-level user logs in to your site. I use this plugin on all of my sites to keep an eye on any unauthorized activity. Not that I’m expecting any, but if it does happen I definitely want to know about it. The plugin size is only 4 KB (zipped) with virtually zero impact on performance or anything else. Win win win, […] Continue reading »

Plugin Planet 2021 Redesign

Finally! Writing this post is the final step in the 2021 redesign of my WordPress plugins site, Plugin Planet. The site launched seven years ago in 2014. I think I spent a couple of months or so building the original site to the best of my ability. That first design stood the test of time, and honestly it would have been fine for another couple of years or more. But after seven years of changes, modifications, swapping out plugins, adding […] Continue reading »

Building the Perishable Press Bookstore

After six months of on-again, off-again hard work (and plenty of unexpected challenges), I am excited to launch the new Perishable Press Bookstore. The old bookstore was located on a separate domain, but I wanted it to be better integrated with the main site here at Perishable Press. So now there is the site blog at perishablepress.com and the store at books.perishablepress.com. Continue reading »

Redesign #25: Performance Over Perfection

Welcome to the 2020 (25th!) redesign for Perishable Press. Like many of the previous designs, the new design is super minimal and organic. The #1 goal this time around was to find an optimal balance between performance and aesthetics. Or put another way.. Continue reading »

Metamorphosis

After 9 grueling weeks, I am happy to say that the 2018 Perishable Press redesign is complete. There are still a few small details that I am contemplating, but overall the work is finished and the site is back to full production capacity. From the old Wire theme rolled out in 2013 (five years ago!), to the minimalist, lightweight X Theme, Perishable Press has metamorphosed into a lean, mean, content sharing machine. This is the 24th time Perishable Press has […] Continue reading »

New WordPress Security Plugin: Host Header Injection Fix

Since version 2.3, WordPress has been vulnerable to a Host Header Injection attack in certain server environments. Over the years, there has been some discussion about fixing the vulnerability, but as of WP 4.9 (beta) nothing has been implemented. So to help those in the WP community who may be concerned (including myself), I developed a new security plugin that fixes the issue: Host Header Injection Fix (HHIF). Continue reading »

How to use the HTML <base> tag

When every byte counts, you can use the HTML <base /> tag to specify a default href and target attribute for all relative URLs on the page. Like a virtual shortcut. For smaller sites with a flat directory structure, this isn’t going to help much; but for sites with deeply nested directories, the <base /> tag can potentially shave a lot of extra weight from your web pages, and also help keep URLs cleaner and shorter. So if you’re micro-optimizing […] Continue reading »

Email Troubleshooting Guide

Email is sort of like the “glue” that holds the Internet together. But it’s the worst possible glue ever. It’s underlying technology is convoluted, complicated, insecure, tedious, sloppy, and archaic. In a nutshell: email sucks but it’s pretty much essential for working online. So what do you do if email is not working, like when you send an email but it never arrives? It can be very frustrating and difficult to figure out what went wrong. To help get you […] Continue reading »

.htaccess Cleanup

Once again I am cleaning up my sites’ .htaccess files. I do this from time to time to remove old redirects, refresh blacklists, and update security and SEO-related directives. It’s tedious work, but the performance and security benefits make it all worthwhile. This post shares some of the techniques that were added, removed, or replaced from .htaccess, and explains the reasoning behind each decision. I do this for the sake of reference, and hopefully it will give you some ideas […] Continue reading »

WordPress Performance Issue Revisited

Following up on my recent performance report with essentially some conclusive results. Turns out that the reported issue is related more directly to the version of PHP than to the version of WordPress. So in other words, WordPress runs a bit faster on newer versions of PHP. As explained previously, after I upgraded my sites to WordPress 4.4, Googlebot reported slightly longer load times for my pages. The slower loading average was seen across numerous sites, and it looked like […] Continue reading »

WordPress Performance Issue?

Just wanted to share a mysterious trend reported for my sites by Google Webmaster Tools, and ask if anyone else is seeing the same pattern. It looks like it’s related to the WordPress 4.4 update, but I’m not 100% sure, so putting the data out there in hopes that others can help shed some light on the issue.. Continue reading »

xy.css moved to Perishable Press

Recently I’ve been implementing SSL on my domains and have been streamlining and updating some projects along the way. Consolidating properties is a great way to simplify workflow and boost productivity, so I’ve went ahead and moved xyCSS from its own domain, xy.css, to its new home here at Perishable Press.
