A new #blog post appears!
I ported the new Hare #compiler to #OpenBSD about two hours ago. This is how I did it.

Hello new followers! I've been bad at hashtags, which are crucial here for discoverability, so here's some of them.
I try to toot interesting things related to #activism about #ClimateChange / #ClimateCrisis / #EarthBreakdown, from the perspective of #degrowth / #ClimateJustice / #sustainability. I'm one tiny part of #ExtinctionRebellion.
I build #FOSS / #OpenSource / #commons and #SmallTech using #rust and will write more about that soon.
Third, occasionally #philosophy, #anticapitalism.

@Ralim Hmmm major Kconfig Conflict between BL602 and ESP32 ... Wonder how the NuttX folks feel about this 🤔

@lupyuen
Hmm…
If each pin can only be used once, could we flip the arrignment matrix and instead have it always have an entry for each pin, which is either a selected value or hi-z by default; then use kconfig rules to prevent collisions ?
(Not sure, haven't used this much tbqh)
Our Grand Plan for syncing and testing Apache #NuttX RTOS on #PineDio Stack #BL604 ... Getting complicated 🤔

@Ralim Here's how we might validate the BL602 Pin Functions at Compile Time...

Compile Time Evaluation in Nim, Zig, Rust and C++

Our #NuttX GPIO Expander for #BL604 implements these GPIO Operations: 1️⃣ Config / Read / Write GPIOs 2️⃣ Attach / Detach GPIO Interrupt Handlers 3️⃣ Handle GPIO Interrupts

@lupyuen Interesting read! Thanks. I am partial to Clojure and the lisps, which he doesn't mention -- lisps might fall behind his call for "modern" languages (because of their age, though this is actually a bad indicator for them), and Clojure definitely disagrees with him about types, but strong agreement on immutability and functional thinking.
