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 »

Deleting Unused Online Accounts

Like many of you, I have been working online for years now, more than most. Over the course of the past 20 years, I have created accounts at hundreds and hundreds of websites. That includes all the work-related stuff, like web development, plus LOTS of social media sites, online services for everything from email to security monitoring. Not to mention all of the accounts created for mundane things like banking, utilities, Internet and phone service, and so forth. 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 »

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 »

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? For example, for my found-images site eChunks.com, I decided to require user login in order to access any content. So now for that site, public access is not allowed, and any posts, images, and all other content is available only to logged-in users. This tutorial explains four ways to make a WordPress site private or members only, so that only authenticated/trusted users […] Continue reading »

Thoughts About macOS Big Sur

macOS Big Sur

I work hard seven days a week. I switched from PC/Win to Mac around 10 years ago because it promised a better user experience. I want consistency more than I want new features. Consistency means greater productivity. I measure the success of each new macOS update based on how much time I have to spend dealing with the changes. Some updates, the changes are minimal and I can keep working without much fuss. Other updates are more extreme, with changes […] 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 »

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 »

WordPress Error Fix: “Call to undefined function get_header()”

[ Call to undefined function ]

I’m seeing a big increase in bot attacks targeting theme files directly. First they get the URL to your theme directory. There are numerous ways for a bot to get this information. For example most themes include assets like CSS and JavaScript files, and the link includes the full URL. So then once they have the theme URL, bad bots will make direct requests for well-known theme template files, like index.php and header.php. Requesting template files directly may reveal possible […] Continue reading »
