Switching from Photoshop to Affinity Photo: Lessons Learned

This post is a bit different than my regular in-depth tutorials. This is where I scribble down notes and thoughts about my experience switching from Photoshop (PS) to Affinity Photo (AP). As I continue to learn AP and collect more notes, I’ll add them to this post. It’s an informal work in progress. To give some context of where I’m coming from, I have around 20 years experience working with Photoshop (and other Adobe apps). Like many others, for me […] Continue reading »

CSS: Center-Align List with Left-Aligned Text (and Unknown Width)

Here is a quick CSS tutorial showing how to center-align a list element with left-aligned text. For example, if you have an <ul></ul> or <ol></ol> of unknown width, and you want it to stay centered on the page and keep the inner text aligned to the left. That’s the trick we’re looking at in this tutorial. 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 »

Remove __MACOSX and .DS_Store from ZIP Files on Mac

Zipping files on Apple/Mac is a chore because of all the hidden files and folders added by macOS. Like .DS_Store and __MACOSX are two of the most common files and folders that are added to zip files when compressed on macOS. The folder named __MACOSX especially is problematic because it contains duplicates of every file in the zip archive. So for example, if you use Finder to compress 20 files, the resulting zip file will contain the original 20 files, […] Continue reading »

How to Ask for Help and Get It

I see so many technical (and other) questions in forums and social media that go unanswered. Not due to lack of trying, but due to lack of understanding. People posting questions like this (an actual post in a popular PHP group on FB): Continue reading »

How to Disable Chrome Scroll to Text Fragment

All the little .txt files you can put in the root directory of your website

The ones I know of: ads.txt humans.txt robots.txt security.txt This site makes use of robots.txt and humans.txt. I don’t need ads.txt because 3rd-party ads aren’t currently running on the site, and security.txt seems not necessary as the site’s contact form is easy enough for anyone to find. Continue reading »

Why Facebook is Not Worth It

Recently I found myself listening to someone who was trying to convince me that I should be doing more on Facebook. For reasons like attracting new customers and making more money. It was pretty sad listening to the spiel, but I do care about people and their opinions, even when they are wrong. Continue reading »

Weird Bug with Highlight.js

Working on adding syntax highlighting to my code snippets here at Perishable Press. To do it, I use my free WordPress plugin Prismatic. Basically all the plugin does is load up either the Highlight.js scripts and styles, or it loads up the Prism.js scripts and styles. So I can rule out the plugin itself for this “weird” little bug. The issue is with Highlight.js specifically. 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 »

7G Out of Beta

The 7G Firewall was released about a year ago as beta, and has had time now to mature/develop into a stable release. So this is just a heads up that 7G is now officially out of beta and ready for use in live/production environments. Continue reading »

The Plan for 2020

I like sharing my plans with those who will listen. For example, last year I said what I was going to do in 2019, and as far as I can tell it is mission accomplished. Now my goals for 2020 are a little more structured and ambitious.. Continue reading »

7G Addon: Stop Aggressive Scanning for Uploads-Related Targets

Around the end of December 2019 and then now well into January of 2020, I’m seeing a massive spike in aggressive malicious scanning for uploads-related targets. In particular, there are massive numbers of requests for URL targets involving uploadify, plupload, and similar. Typical scans hitting upwards of 30K–50K requests per attack. Just relentless exploit scanning on steroids. Continue reading »

How to Modify GET and POST Requests with WordPress

I’ve written before about protecting against malicious POST requests using Apache/.htaccess. In this tutorial, we’ll look at how to modify GET and POST requests using PHP and some core WordPress functionality (with no .htaccess required). Normally you would want to manipulate URI requests at the server level, but that’s not always possible (like on shared hosting). So in those cases where you want to modify GET, POST, or other types of requests on a WordPress site, check out the following […] Continue reading »

How to Disable WordPress Automatically Generated Images – Complete Guide

As you may know, WordPress creates numerous copies of all images uploaded via the WP Media Library. These additional images are generated in various sizes, depending on your settings and other factors. This may be totally fine in general, but if you are working with lots of images on your site, the extra files can really eat up your disk space. This can be wasteful, specially if your site does not make use of all the extra images. So to […] Continue reading »

Case of the Invisible CSS ::selection

Recently I noticed a weird bug in my free WordPress security plugin, Banhammer. For some reason, I could not select any text on the page. Usually when you click and move the mouse cursor over some text, it becomes highlighted and displayed in some other color. But this wasn’t happening on the Banhammer settings screen. No matter which HTML/text I tried to select, it just wasn’t working. T’was a real mystery.. Continue reading »
