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.

With PreviewMarkdown 1.3.0, you can now preview files’ YAML content too

How to migrate to native Homebrew on an M1 Mac

Let the great Homebrew migration begin. Yes, Homebrew now has native support for Apple’s ARM64-based M1 chip. The latest version, 3.0.0, released 5 February, will run nicely on your Apple Silicon Mac. There’s a catch, of course. Well, several catches: first, not all of the tools you can install using Homebrew are M1 native yet and, second, Homebrew doesn’t offer explicit migration instructions, that I could find at least.

How to debug a Raspberry Pi Pico with a Mac, SWD and… another Pico

When you’ve used Serial Wire Debug (SWD) to help you correct the C or C++ code running on your Raspberry Pi Pico, you’ll never want to go back to USB and the UF2 file system again. I don’t — no more messing about unplugging and re-plugging cables for me.

How to program the Raspberry Pi Pico in C on a Mac

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.

A first look at a MicroPython marvel: the Raspberry Pi Pico, in partnership with a Mac

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.

Apple Silicon survival notes — day one with an ARM Mac

You have to take your hat off to Apple: it knows how to transition from one processor architecture to another, completely incompatible one. It did it in the mid-1990s with the switch from the Motorola 680×0 series to PowerPC, then again a decade or so later when it put Intel inside new Macs. Now we get ARM.

Tap Homebrew to easily install and upgrade your own apps

The package manager I use on macOS is Homebrew, Brew for short. This is a great open source tool for installing command-line apps and utilities, and keeping them up to date. It’s essentially the Mac version of the Raspberry Pi’s apt. So much of the software I use on a regular basis — the nano text editor, Node.js, Python 3, the shellcheck shell script linter, the hugo website builder, the sass CSS wrangler and a whole load more — were added and are maintained using Brew.
