@lupyuen Interesting move, I think that the most interesting things in a near future will be on RISC-V 🤔

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)
