Ask HN: Anyone Waiting on BT Auracast?
Hey folks. Anyone out there waiting for BT Auracast? It was announced June 2022, and immediately struck me as must have.
I lost my earbuds, but it seems ridiculous to get a replacement without Auracast, seems like surely if I'm going to make a decent sized purchase like that it needs to support group playing. I want to tune into the radios of other people on the metro or on the bus, want to be able to watch a movie on the plane with someone.
Auracast was announced in June 2022. Anyone else out there struggling with expectations here? I'm really hoping the product announcement season that's right around the corner had a good number of Auracast announcements.
Side note, a ton of it is over my head but it's been so so fun tuning in every once and again to see how Zephyr's Bluetooth Audio work is going. Just wild now much has gone into this! https://github.com/zephyrproject-rtos/zephyr/commits/main/subsys/bluetooth/audio

VisionFive 2 ROM addresses for Zephyr RTOS
I am working on adding support for VisionFive 2 in Zephyr RTOS. I have created a device tree by referencing the starfive linux, patches of hifive_unmatched FU740 SoC and patches of BeagleV Starlight.

Adding support for visionfive2 in zephyr rtos
We are unsure on how to proceed further with this error. We have opened a github discussion regarding the same issue.

Learning to write device drivers using C/C++ in Zephyr OS
Then there are samples. Look through it for anything useful. RC522 uses SPI, so getting that to work would be a good first step.

Building with cmake can't find cross-compile objcopy
Hey, I've been trying to build an app with cmake+ninja instead of west to integrate it into a larger build system and everything works correctly except for the final stage where it uses `/usr/bin/llvm-objcopy` instead of the `${CROSS_COMPILE}` one it tries to find here.

Arduino Joins Zephyr Project
Zephyr has a lot of good points, but I really wish it didn't use Kconfig. Getting a working config seems to be mostly a matter of copying an already working example. It might be okay for hardware side of things, but it's a really bad at software/feature dependency.
Set https://docs.zephyrproject.org/latest/build/kconfig/tips.htm... and the issue: https://github.com/zephyrproject-rtos/zephyr/issues/52575. And don't even get me started on trying anything to group options together.

PlatformIO and Zephyr is a bad idea
In this thread u/ikravets explained that there hasn't been much demand for Zephyr, which is why they aren't doing anything with it, and in this pull request Zephyr decided to no longer recommend PlatformIO in their documentation.

Bun - The One Tool for All Your JavaScript/Typescript Project's Needs?
NodeJS is by no means a slow runtime, it wouldn’t be so popular if it was. But compared to Bun, it’s slow. Bun was built from the ground up with speed in mind, using both JavascriptCore and Zig. The Bun team spent an enormous amount of time and energy trying to make Bun fast, including lots of profiling, benchmarking, and optimizations.

ntdll.dll!RtlUserThreadStart()
There are valid reasons to use APIs from NTDLL. Where I disagree with zig#1840 is the idea that it is always better to use NTDLL versions of API. Every other software ecosystem uses the standard Win32 APIs and diverging from that without a good reason seems like a good way to have unexpected behavior. One concrete example is most users and programmers expect Windows to redirect some file system paths when running on WOW64. But this is implemented in Kernel32, not ntdll.
