Fixing Intermittent Slowness and Timeouts on WordPress Sites

I’ve been responsible for maintaining a number of WordPress websites in my time, some larger than others. This one, for example, gets almost zero traffic, but I like to think that the hits I do get to this site are people looking for very specific answers that I’ve been able to provide. Today I’m going to try and add another helpful insight about WordPress optimization and troubleshooting with the hopes that it might help someone else in the future.

Implementing a security.txt File on the NY Times Website

I finally did it — I achieved one of my lifelong goals: something I wrote was published on nytimes.com! Not exactly in the way you might imagine though, as the file that was published was a brand new security.txt file. You can read all about the concept and how it helps improve the security of The Times over at the Open blog, where the article I wrote was just published.

Configuring SNMP Monitoring for Fedora Workstation

I’m writing this more to remember this for myself than any other reason. I’ve had to do this a couple times, and every time I seem to forget the important steps. So here it is.

Fixing AMP Ads That Break Your Website Layout

I maintain a couple of blogs, one of which is the whiskey review site Thirty One Whiskey. That blog actually gets a good amount of traffic, and generates enough revenue from Google ads to (partially) fund my whiskey and cigar habits.

One problem that I had been running into was that the default code for Google’s AMP ads was breaking the formatting of my website on mobile devices. When rendered, the ad element was wider than the width of the page on mobile screens, so when you started to scroll, quite often the page would move to the left a bit and the text would start to be cut off.

Adding a Featured Image to All Posts in WordPress in One Easy Click

Featured images are sometimes an afterthought. For older bloggers, featured images weren’t really a critical part of the web layout and often weren’t added to posts. And for newer bloggers, it’s just one more step that doesn’t seem necessary. But then there comes a point where you want a new theme that requires featured images to work, and now you have hundreds of posts without that featured image.

Querying And Displaying WordPress Site Stats Using a PHP Script

I like being able to keep an eye on everything that’s going on with the stuff I run. To that end I run a LibreNMS deployment in my house that monitors all my equipment, and I’v got a dashboard that gives me the vital statistics for everything I care about in one glance. One thing that has been sorely missing was a widget where I could see the stats for my WordPress sites, and I think I finally figured that out this week.

Performance: LogMeIn Versus TeamViewer

I use a MiniX Neo headless mini PC as a jumpbox into my home network. For the last couple years I had been running LogMeIn as the remote access client to connect back into the device, but with the recent pricing increase and lack of support for the iPad application I decided it was time to switch to TeamViewer. I knew that having an agent running on the device at all times would cause a performance hit, but I didn’t realize just how bad that hit would be.
