Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Winterbloom introduces Micronova: a tiny but mighty Eurorack power supply
I'm glad you enjoyed it! We're serious about open source and that means we gotta be serious about documentation. If you want a really fun one, check out https://gemini.wntr.dev ;)

How do you build your source code?
We use ninja - a very small and fast build system. Ninja generally needs something to generate its build files (CMake, Meson, etc.), but we just use a little Python script to generate ours.

Matriarch, modular, and Felt Instruments
Winterbloom also has something similar with their interactive user guide for Castor & Pollux (their latest Eurorack-format synth module). It's geared towards beginners and explains a lot of things that are useful even if you don't ever plan to get that module or any modular gear at all.

Small/unknown Eurorack makers?
Plus the modules are really cool and unique. Sol and BHB are both programmable with CircuitPython. All the hardware and firmware are open source for all the modules. Thea is also suuuuuper good about documentation too; check out this interactive user guide for Castor & Pollux!

Duophonic jam with Castor & Pollux, a juno-inspired dual osc
C&P is the latest, and most complex yet, by my favorite indie module maker, Winterbloom. I pre-ordered as soon as it was available to do so and they finally started shipping recently. The manual is pretty sweet and really interactive and educational too. RMR did a really good video demoing the wide range of sounds this can produce; highly recommend checking it out.

Anyone help Compile and Program MCU for Castor and Pollux for trade of PCBs
Hey there, I wrote some build instructions in the contributing guide on GitHub: https://github.com/wntrblm/Castor_and_Pollux/blob/main/CONTRIBUTING.md#building-the-firmware

Here's a Juno style DCO I just made
This is great! I love a good minimal implementation. If anyone is looking for a complete Juno-style DCO, you might be interested in Castor & Pollux- the module that I wrote that Juno article for. It's also completely open-source, and you can find the schematics and source code here.

Future of 32-bit platform support in FreeBSD
For the modern server/desktop and even laptop, that's also no bad thing. It is somewhat ridiculous that UEFI bioses, internally, still boot in 16-bit real mode and have to do all the steps your bios bootloader used to do to set up a 64-bit environment ready to go: https://github.com/tianocore/edk2/blob/edc6681206c1a8791981a..., https://github.com/tianocore/edk2/blob/edc6681206c1a8791981a..., https://github.com/tianocore/edk2/blob/edc6681206c1a8791981a...
Why not just start the CPU in "long mode", which is what everyone is using it for, in the first place?
These newer ARM processors support 32-bit code at EL0 only (userspace). That seems like a reasonable approach for x86 as well and the freebsd announcement has this to say:
> There is currently no plan to remove support for 32-bit binaries on 64-bit kernels.
So for the moment, you can run 32-bit applications just fine.

AMD to move to open source firmware in 2026
From there you'll need to get an EFI Shell. There may be one built into your system, but you can also get one here from Tianocore (aka, the people mostly making UEFI). Neither this EFI Shell nor Keytool.efi (the thing you need to load the keys) are signed of course, so you will need to turn off SecureBoot to continue. From there just run Keytool with your new keys, turn back on SecureBoot, and move on with your life.

Windows installation doesn't boot up when I try to use UEFI firmware
I had the same issue. What fixed it for me was compiling my own OVMF.fd file from here and using that to boot. The version of OVMF that shipped with fedora was broken for me for some reason.
