Replacement for JavaScript Errors Notifier (Chrome Extension)

Heads up about the JavaScript Errors Notifier extension for Google Chrome. Looks like it was removed from the Chrome store sometime last year. Not sure of the reason behind it, but can tell you that currently there are no suitable extensions to replace it. Kinda sucks because JavaScript Errors Notifier was one of my favorite “always on” extensions. It makes it easy to spot any JavaScript errors as you develop, design, or browse the Web. Fortunately there’s still a way […] Continue reading »

Check Your Spam Folder

Check Your Spam Folder

It’s sad that we’ve arrived at a place where it needs to be said. Unfortunately, 3rd-party email services such as Yahoo, Hotmail, Gmail, and so forth have to deal with tons and tons of spam. So they tend to use very aggressive spam-filtering rules. Overly aggressive, in many cases. Continue reading »

Important Notice for Email Subscribers

Whoops! I spaced off sending this before July, so figured better late than never :) Hello! As you may have heard, Google/Feedburner is dropping support for their “Subscribe via Email” feature. This free service grabs the latest content from a site’s RSS feed and delivers it via email to a list of subscribers. So whenever a new post is published here at Perishable Press, Feedburner delivers an HTML-formatted copy direct your inbox. The subscribe-via-email service has been available for years […] 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 »

Vanilla JavaScript Toggle Divs Based on Radio Select Inputs

Working on the redesign of Plugin Planet, I needed a way to toggle between two divs based on which radio input is selected. This is useful for showing option-specific information conditionally, depending on the current active radio select field. This tutorial shows how to achieve it using vanilla JavaScript, so there is no need for including an entire library like jQuery. Very simple technique, requiring minimal amount of HTML markup and vanilla JavaScript. Continue reading »

Disable Apache mod_rewrite Rules in any Subdirectory

Let’s say you have some .htaccess rewrite rules in place using Apache’s mod_rewrite. By default if the rewrite rules are located in the root directory, they will be applied to every subdirectory, as expected. But what if you need to disable the rewrite rules so that they do not affect some specific sub-directory or sub-folder? This super quick tutorial shows the easiest way to do it. Continue reading »

4 Ways to Make a WordPress Site Private Access Only

LOTR: Doors of Durin

Have you ever wanted to make a WordPress site private? So that only specific users are allowed access?

This tutorial explains four ways to make a WordPress site private or members only, so that only authenticated/trusted users […] Continue reading »

Switching from Photoshop to Affinity Photo: Lessons Learned

Affinity Photo

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 »

Remove __MACOSX and .DS_Store from ZIP Files on Mac

[ The Cleaner ]

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

[ Screenshot of pathetic Facebook post ]

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 »

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 »

How to Modify GET and POST Requests with WordPress

[ POST Requests ]

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 »
