Leon Mika ☛ Devlog: UCL - Bytes Slices
The first is a new object type called BytesObject, which encapsulates a simple byte slice. To create this object, I added a new builtin with the name bytes:from. This produces a BytesObject from, well, pretty much anything actually. Pass in a string, and it will return a BytesObject from the raw bytes encoding the UTF-8 runes. Provide it with a list or iterator of integers, and it will convert each one into a byte, and assemble it into a BytesObject. It also takes other BytesObject, which will copy (or concatenate) the individual args into a new slice. Passing it nil or providing no arguments will produce empty slices: [...]

Jim Nielsen ☛ The Bulldozing of an Interface
And when you bulldoze an interface to build a new one, comparing the old vs. new side-by-side to make sure you “captured everything” is a lie. It’s never obvious what has been lost because the interactive pieces are missing from the static images — and those are what matter most because it’s how the feature works!

RTL-SDR ☛ Instro: Python Hardware Instrumentation Library Adds RTL-SDR Support
Instro is an open-source Python library designed to talk to test instrumentation such as power supplies, multimeters, electronic loads, DAQs, oscilloscopes, and PLCs from a unified, typed API. The maintainers describe the goal as follows: "Code against an instrument category once, then swap vendors with a single configuration change. When you want to capture the data, attach a publisher to stream it to a file, Nominal, or a destination of your own." A library like this saves engineers from having to write custom drivers for each piece of equipment.
