Last week I tried the Raspberry Pi Pico with MicroPython. The Raspberry Pi Foundation would be sufficiently commended for providing only this level of programming support. MicroPython leverages the Python skills of the many Raspberry Pi users out there and is accessible to plenty of others too. But the Foundation has also provided a C/C++ SDK, and this opens the Pico up to serious embedded-system developers too.

On Thursday morning I awoke to the news that the Raspberry Pi people have entered the microcontroller board market with a new product, the Raspberry Pi Pico. Before I’d even got out of bed, I ordered a couple. Well, at £3.60 a pop, why not? I’ve now had a chance for a quick play, and here are my findings.
Continue readingOi, app makers, no! Enough Markdown monkey business!
PreviewMarkdown, my modern QuickLook plug-in for Markdown files, was recently updated to version 1.1.4. It was a minor change, which is why it wasn’t announced here, but the reason for the update may interest to anyone keen to understand the workings of macOS. It also highlights some inconsiderate behaviour on the part of some Mac software developers.

Periodical publishing is not what it was. Gone are the days when week in, week out millions of adults and kids would buy magazines or comics and spend time reading them. We will not see their like. Now it’s all about screens, not paper, and grabbing digests of information fed from social media streams. I’m not saying that’s a bad thing, just that, in the digital era, no one will ever feel the almost physical thrill of taking possession of the latest issue of a favourite title — or be eager to understand what makes the minds behind it tick.

imageprep, my command line tool for batch-processing picture files, had a big update a week or so back — and now it has another one. With the second update imminent, I didn’t announce the first, 6.1.0, which I released to coincide with my post on writing command line utilities in Swift. That done, it’s time to shout about imageprep 6.2.0.

How To Write macOS Command Line Tools with Swift
I’ve spent a lot of time of late working on several macOS command line tools written in Swift. So I’ve gathered together the key points I’ve learned while creating and updating pdfmaker and imageprep: some best practices and ways to deliver many of the features common to programs the run at the command line.

I’ve just posted updates to a couple of applications. Both can be grabbed from my website or installed using Homebrew.
Continue readingOut now: a Swift-ier version of imageprep
I’ve just released version 6.0.0 of imageprep, my macOS command line tool for processing batches of images. Born a shell script, imageprep has now not only finished school and graduated from college, but also has gained employment as a fully compiled application. It’s written in Swift so it’s quicker these days.

I like clocks, and the digital variety make fun little projects. Here’s an example: a tiny LED timepiece based on a trio of Adafruit Feather parts.
