For a couple of months I’ve been getting a trickle of badly-put-together (but frustratingly well-spoofed) extortion spam at my main website e-mail address.

I recently got my hands on a Raspberry Pi 4 to add to my network thanks to Pimoroni, and of course it wouldn’t be complete without a cooling solution. Pimoroni also offers a heatsink case which both protects and passively cools the computer. Since the Pi 4 runs hotter than previous versions, I wanted to make sure it would have plenty of cooling, and this case was exactly what I was looking for. It gives 10-15 degrees of passive cooling according to their testing!

Yes, the custom lightbox plugin I developed for my website’s photos page is finally officially released! It is lightweight, functional, nice-looking (in my opinion at least), and it even does a little trickery when the page loads to make it a bit harder for visitors to download copies of your images.

This week I set up a pi-hole on my home network, and apart from a couple of minor hiccups, it has been very nice so far. If you haven’t heard of it, pi-hole is software that handles DNS requests and blocks online ads for every device on your home network, even on devices which won’t normally let you install a plugin like Adblock Plus (like smart TVs and un-rooted phones). The installation guide was nice and simple, and even setting up a DNS-over-HTTPS client was pretty straightforward.

For some time I’ve been noticing a strange issue on my website: every once in a while, a file named error_log would appear in a subdirectory of my document root, visible to anyone who knew to look for it. It seems that whenever there was a PHP error (for example, when a vulnerability probe tried to access a theme file), PHP would dump the error message to a file in that same directory.

I have to change my proxy settings pretty regularly for work, so earlier this week I researched how to streamline that process a bit. The first thing I found was how to create a shortcut to a particular settings page. It’s relatively easy if you know the URI for the page you want, and there are plenty of lists out there, including this one at Windows Ten Forums. Just create a shortcut and put the URI of the page you want as the location. In this case I’m going to point the shortcut at “ms-settings:network-proxy”

Now that my website redesign is complete-ish, or at least launched, I’m starting to work on cleaning up and releasing some of the custom code I wrote to make it happen. This is one of those pieces: a tiny, lightweight plugin that removes unneeded stuff from the head section of each page to make everything a little more lightweight, improving loading times, bandwidth usage, and site security.

I was very happy to find out that Android 10 ( R.I.P. dessert-themed version names) has support for freeform windows that’s easily enabled. It’s been around for a few years, but this is the first version of Android where you can get at it without using ADB or a third-party app.

Note: while my first camera is still very broken, I have since gotten back into photography with a fancier and (slightly) newer camera, not to mention some fancier, and in some cases, much older lenses.

I got my first DSLR in 2015: a Pentax K-50, the absolute cheapest camera with a large-ish sensor that I could get brand new. It had a lot of features that you don’t always see on a consumer-grade camera though, like a pentaprism viewfinder instead of pentamirror, dual control dials, and weather sealing. It was absolutely the best bang for the buck that I could have hoped for, and it was a stalwart companion for many a hike and concert.

I’m very excited to announce a new version of my website! This has been a very long time coming, but I have finally redesigned it in WordPress and added a bunch of new content. It will be a lot easier for me to add more on an ongoing basis too, and I plan to write blog posts every so often about my software projects.
