Battle of the AIs - Embedded Developer There is little doubt that the use of AI in coding is improving developer productivity both in the production of code and also diagnosing issues. AI can bring a large corpus of data into one place.…

CoPilot - I think 98.3% would be adequate:

Unblocking the printer nozzle on the Bambu printer...

Not as scary or difficult as I thought.

FileVault mysteriously re-enabled after Tahoe 26 -> 26.1 upgrade. Wonderful !

Why Wonderful ! - It turns off remote connections.

Time to grab a keyboard and monitor and logon to each Mac and reconfigure so I get remote access back.

WONDERFUL !

Something I've kept for many years - a log book with designs and results. A good excuse to get the fountain pen out :)

Getting Started with Rust - Enums - Embedded Developer Using enums in Rust with data and method implementations.

The enums chapter 6 of The Rust Programming Language hinted at methods implemented against an enum implementation. Had to do some research on how to use methods:

Affinity Photo has always been a good value rival to Photoshop. I have been using it to edit my photos for 10 years.

Now Affinity Photo is part of Affinity Studio and it is free. You only pay if you want the Canva AI features.

C/C++ Constness - Embedded Developer Constant pointers and data is C/C++

I find writing about something helps with remembering so let's see if this helps me remember where const should go in a C++ function declaration as I always have to double check:

Getting Started with Rust - Ownership, Borrowing and References - Embedded Developer Ownership, borrowing, structures, methods and references in Rust.

Still getting to know the Rust programming language, this week Ownership, Borrowing, Structs and References.

Currently learning Rust and week one has been an easy enough start. Week two is going to take me into the realm of ownership and that is going to be a little more taxing.

Everyday is a learning day

One size fits all - madness that way lies.

Fun and games with the Raspberry Pi Imager. The current release 1.9.6 does not allow username / password login over SSH.

Took several hours to find the solution.

Solution: Downgrade to 1.8.5.

So sad to hear about Jim Lovell.

Always good to hear @scott.hanselman.com speak. This talk is fantastic covering tech; what was promised, what was delivered and how we need to assess what we consume.

Loved this article, been trying to get QEMU working with Espressif chips (on and off) for a while.

In my experience with LLMs and coding we have a 50/25/25 Rule:

50% of the time - Great code that works
25% of the time - OK, I'll just add a few corrections / tweaks
25% of the time - The code is rubbish

Still, I can read and correct faster than I can type 200 lines of new code.

Three SPI Busses Are One Too Many on This Cheap Yellow Display

Isometric image of a white PLC box with a Praysio logo, screen, buttons, USB plug and wire terminal plugs for RS458, MBUS, Ethernet, etc.

Loving this beautiful Praysio industrial machine monitoring device built on Meadow!

Started to use a Cheap Yellow Display and hit a problem with using LCD, Touch sensor and SD Card at the same time.

Small hardware modification fixed the issue:
