Project mention: Show HN: CompressX, my FFmpeg wrapper for macOS, made $9k in the last 4 months | news.ycombinator.com | 2024-04-10GPL2
Since FFmpeg is GPL2, doesnโt that require CompressX to disclose its source code?
IANAL, apologies if I miss understand license requirements.

Project mention: The GitHub Black Market That Helps Coders Cheat the Popularity Contest | news.ycombinator.com | 2023-10-23> Another giveaway is the ratio of stars to watchers / forks. I remember one project with thousands of stars but only 10 users "watching" it. They went on to raise a sizable seed round too.
Not necessarily indicative of foul play. I have two projects like this (https://github.com/smacke/ffsubsync and https://github.com/ipyflow/ipyflow) and I attribute it to not having great developer documentation.
There's an issue open for this: https://github.com/gqrx-sdr/gqrx/issues/1104
I could really use some help from a software build expert. Gqrx and all its dependencies would need to be built in CI with Apple silicon support, and I don't know how to do that.
Project mention: [P] - VkFFT now supports quad precision (double-double) FFT computation on GPU | /r/MachineLearning | 2023-09-27Hello, I am the creator of the VkFFT - GPU Fast Fourier Transform library for Vulkan/CUDA/HIP/OpenCL/Level Zero and Metal. In the latest update, I have added support for quad-precision double-double emulation for FFT calculation on most modern GPUs. I understand that modern ML is going in the opposite low-precision direction, but I still think that it may be useful to have this functionality at least for some prototyping and development of concepts.
Project mention: Are there any libraries that I can use or any way to make such audio waveforms? I looked into a library called "react-native-audiowaveform" but it's not being maintained anymore and doesn't work for newer versions of RN | /r/reactnative | 2023-05-21https://github.com/dmrschmidt/DSWaveformImage for iOS
I'm the main author of Highway, so I have some opinions :D Number of operations/platforms supported are important criteria.
A hopefully unbiased commentary:
Simde allows you to take existing nonportable intrinsics and get them to run on another platform. This is useful when you have a bunch of existing code and tight deadlines. The downside is less than optimal performance - a portable abstraction can be more efficient than forcing one platform to exactly match the semantics of another. Although a ton of effort has gone into Simde, sometimes it also resorts to autovectorization which may or may not work.
Eigen and SLEEF are mostly math-focused projects that also have a portability layer. SLEEF is designed for C and thus has type suffixes which are rather verbose, see https://github.com/shibatch/sleef/blob/master/src/libm/sleef... But it offers a complete (more so than Highway's) libm.
Since you're using an ARM, you've also got access to CMSIS-DSP, which has most basic DSP functions you'll need already hand optimized for whichever ARM core you have: https://github.com/ARM-software/CMSIS-DSP
Project mention: IQEngine: A React-based FOSS project for sharing and analyzing recordings of wireless signals | /r/webdev | 2023-12-04One thing we have struggled with is the relatively small intersection between wireless engineers/researchers, and web developers. We are definitely looking for more folks with web dev xp to get involved, and in return you can build expertise within a specific and "hot" field, ie wireless =).
