How to Open a Tor Brave Window from Command Line / / No Comments I love the Brave web browser for many reasons: ad blocking, Brave rewards, crypto integration, and even a Tor tab feature.

Another Update to my Slideshow Web Component – JavaScript Support / / No Comments Last month I shared a simple web component I built to embed slideshows onto web pages. If you didn’t get a chance to read that, you can see it in action in this CodePen below: See the Pen Slideshow Web Component by Raymond Camden (@cfjedimaster) on CodePen. After I wrote this, Šime Vidas shared an excellent update to my component with some great modifications.

When I demonstrated how to use my web component, it was done via a script include (well, it’s on CodePen, but you get the idea), and then a bit of HTML. Here’s an example.

How to Create a Diff of Two Images / / No Comments When I was a child, I loved looking for Waldo in the “Where’s Waldo?” book series. These days I’m a sucker for TMZ’s “What’s the Big Frigin Difference” images, where TMZ slightly changes an image and you have to spot the differences between the two.

To create a diff of two similar images, we’ll use ImageMagick’s convert command line utility with a large host of configurations: convert '(' image1.png -flatten -grayscale Rec709Luminance ')' '(' image2.png -flatten -grayscale Rec709Luminance ')' ... more → Posted in: JavaScript Tagged with: create, Diff, images

How to Open an App from Anywhere on Mac Command Line / / No Comments Many engineers like myself live in the command line, and perform actions from command line that most others would click an icon for. I’ve always found opening apps from command line on Macs painful. You need to references the Applications directory, add .app to the name, etc. I just want to open apps by name.
