@Blort That repo contains some stuff on CEVA's WiFi IP, that I discovered on GitHub some months ago. I wrote about it here: https://lupyuen.github.io/articles/wifi
@jeancf They seem to be very old vulnerabilities ... GitHub just started scanning of Rust Vulnerabilities, so I got a huge bunch of notifications overnight

#ZigLang Compiler can't Auto-Translate some tricky C Macros into Zig ... Here's a workaround
"Apple, stop this nonsense and just put a decent camera in your laptops already"
"Singapore's Dengue 'Emergency' is a Climate Change omen for the world"
Auto-Translating C to #ZigLang is not perfect (like for C Bit Fields) ... But we can fix it ourselves

Good Morning #RustLang Vulnerabilities 🤔
#ZigLang Compiler will helpfully Auto-Translate our code from C to Zig ... Rewriting C to Zig gets so much easier 👍

@lupyuen Yes, I have known about this for about 20 years. I recall one benchmark that to outperform the vector-insert-in-the-middle for a random element, the collection in the benchmark had to be >50,000 entries.
Then to complicate further, it is language sensitive, since for objects, OO languages (all?) need to make the vector a vector-of-pointers-to-objects, compared to an array-of-structs (or struct-of-arrays) in C.

#ZigLang Newsletter for the week
This is how we call the #LoRaWAN Library from #ZigLang
https://github.com/lupyuen/zig-bl602-nuttx#convert-lorawan-app-to-zig
Here's how we import #LoRaWAN Library from C into #ZigLang ... Yep Zig understands C Header Files! 👍
https://github.com/lupyuen/zig-bl602-nuttx#convert-lorawan-app-to-zig
We take this #LoRaWAN App in C and convert to #ZigLang ... 700 Lines of C Code, no sweat!
