Displaying exif information in WordPress posts

After discovering that WordPress modifies img tags when rendering a page, it crossed my mind that I could display exif information underneath each image on my new photography blog. The basic process is applicable to any manipulation of the content that you would want to do before it is displayed. To do this, we add a new filter to the the_content hook: add_filter('the_content', function ($content) { // manipulate $content return $content; }); As with all… continue reading.

Images and WordPress

My new WordPress project has multiple photographs per post and as I wanted them to work in an efficient manner for multiple screen resolutions. The secret to this is the srcset and sizes attributes on the img tag. It turns out that WordPress will create multiple sized thumbnails when you upload an image. It will also add the srcset and sizes attributes into your img tags for you if your image tag has a class… continue reading.

Creating virtual environments with Pyenv

Using a separate master password in 1Password for Mac

I really like the 1Password password manager and recently switched to using the subscription based account. This allows access to my passwords via the web so, as you can imagine, I have a very strong 35 character master password set. On my Mac, I use the 1Password app and that requires me to enter my master password reasonably frequently, so this very long password is not so desirable here. I'm comfortable that a 12 character… continue reading.

In order to understand what was happening, I really wanted to inspect variable at certain stages of the process, which is easiest with a step debugger. As I already use PhpStorm for step debugging PHP, I fired up PyCharm and worked out… continue reading.
