Raspberry Pi Pico proxies: the Pimoroni Tiny 2040 and the Adafruit QT Py RP2040

Having spent some time with the Raspberry Pi Pico, I thought it was time to try out some of the other RP2040-based development boards that have become available. When it launched the Pico, the Raspberry Pi Foundation said it would make its RP2040 microcontroller available to third-party board makers. Retailers Pimoroni and Adafruit were among the first to toss their caps into the ring. Their offerings: respectively, the Tiny 2040 and the QT Py RP2040.

Stay ahead of git with this sharp script

I work on quite a few git repositories at once, and I don’t always commit changes in one before making changes to another. Or if I do, I don’t always push the changes up straight away. That might not be best practice in software development, but hey, it’s what I do. The issue for me is remembering what state each repo is in. Here’s the script I use to tell me.

Crop picture files with confidence and pixel-precise offsets, using sips and imageprep

I recently had a rather large number of screenshots to process: specifically to crop them down to a small area about a third of screen width in and two-thirds of its height down. I could have done this manually, but it’s easy enough to make mis-crops when you’re cropping a couple of images by eye, let alone a 100 or so. The solution? Get your Mac to do it for you. Here’s how.

How to fix ‘xcodebuild’ macOS Terminal slowdowns

For a while, running commands and scripts in macOS’ Terminal has felt slower than it should, especially when opening Terminal for the first time. Clearly my .zshrc file was being run, but there was a very noticeable pause between the completion of the script and before the prompt appeared. The gap was much less on my M1 Mac than my Intel machine, but still noticeable. Got the same problem? Here’s how to fix it.

Last week I announced the release of a new version of PreviewMarkdown that will preview YAML front matter in Markdown files. Work on that release prompted me to code a new app that enables QuickLook previews and Finder icon thumbnails of YAML files.

Now available: PreviewMarkdown 1.3.0 with YAML support

Version 1.3.0 of PreviewMarkdown has just been released. Its key new feature: you now have the option to view YAML front matter in Markdown file previews. This is really handy if, like me, you use a static site generator and use YAML to record content metadata at the top of your Markdown page files.
