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.

Upsampling in Gnuradio is necessary?
In gr-dtv transmitter examples for Gnuradio, I see some times people use a resampler block before the RF hardware sink. Say our sampling rate is ~9.14Msps which satisfies the Nyquist criterion because our samples are complex numbers.

Capturing FM using SDR
2.1. Thanks for that tip, I forgot that I was able to check the source code of the WBFM Receive block. As you have said, there are mostly the same. There are some differences between how values are picked. The WBFM Receive block would be a synonym of Quadrature demod => Fir Filter (decimation => Low pass filter) => FM Deemphasis. 2.3. My question there is why 10 and not 20 or 100. I understand that the idea is to reduce the sample rate asap, but what I don't understand is why those values were picked and how can I understand what would be the "correct" or "best" value. 2.4. I'm not fully understanding what you said. If I check the WB FM recieve source code the values that are supplied as the cutoff freq and transition width of the Low pass filter differ from the one of the example. The webfm would apply a sample rate / decimation / 2 - sample rate / decimation / 32 as a cutoff freq and a sample rate / decimation / 32 as a transition transition width. Calculating those values would end up in different that the ones supplied in this second example. Again, is there a rule of thumb to pick these values?.
- Hello everyone! I would like to install and run GNU Radio version 3.7.4 in order to follow along with The HackRF GNU Radio tutorial on greatscottgadgets.com/sdr/ but I can’t find prior releases to install. Can anyone help?

Multi band gfsk demodulation with Nooelec RTL-SDR v5 SDR and gnu radio
Gaussian filter is used only on the tx side, so specifying bt in the receiver makes no sense. Take a look at gfsk mod/demod blocks implementation: https://github.com/gnuradio/gnuradio/blob/master/gr-digital/python/digital/gfsk.py

Is there a way to delay a signal in time-domain?
Here's the filter coefficients used for the GNU-Radio interpolator block to get you started. This is a 7th order interpolator (i.e., 8 FIR taps) with very good performance. Each "row" of the array sets the delay in steps of sample_time / 128.

My grandpa is a huge HAM radio fan, so I showed him GNU Radio. Got this text the day he got back home.

runa - a wayland compositor toolbox in Rust looking for collaborators
Regarding smithay being production ready, it's bug tracker mentioned it does not implement "idle-inhibit" , iirc that means you can't watch a movie without the lock screen being activated, i would argue most people would not consider that a production ready library.

How to learn writing a Wayland compositor?
Understand Wayland concepts: Familiarize yourself with the basic concepts and principles of Wayland. This will help you gain a solid understanding of how the system works. You can refer to the official Wayland documentation (https://wayland.freedesktop.org/docs/html/) and the Wayland book (https://wayland-book.com/). Learn Rust: If you're not already proficient in Rust, take some time to learn the language. The Rust Book (https://doc.rust-lang.org/book/) is a great place to start. Study existing Wayland compositors: Since you mentioned Anvil and smallvil, you can study their source code to gain insights into how they're designed and implemented. Try to understand the structure and how different components interact with each other. Dive into Smithay: Smithay (https://github.com/Smithay/smithay) is a Rust library for building Wayland compositors. Familiarize yourself with the library and its components. You can start by studying the provided examples and reading the API documentation. Learn graphics programming: Since you're interested in graphics effects, you'll need to learn about graphics programming concepts, such as shaders, framebuffers, and texturing. Vulkan (https://www.vulkan.org/) is a popular graphics API that you can use with Rust. Check out the following resources to learn more about Vulkan and graphics programming in Rust: Vulkan Tutorial (https://vulkan-tutorial.com/) gfx-rs (https://github.com/gfx-rs/gfx), a Rust graphics library Vulkano (https://github.com/vulkano-rs/vulkano), a safe, pure-Rust wrapper around the Vulkan API Start small: Break down the compositor project into smaller, manageable tasks. Begin by implementing basic functionality, like setting up a window and drawing simple shapes. Gradually add more features, such as input handling and window management. Ask for help: Join the Wayland and Rust communities to ask questions and seek advice. You can find them on forums, mailing lists, and chat platforms like Discord or IRC. The Wayland mailing list (https://lists.freedesktop.org/mailman/listinfo/wayland-devel) and the Rust programming subreddit (https://www.reddit.com/r/rust/) are good places to start. Iterate and experiment: As you progress, keep experimenting with different graphics effects and shaders. Try to implement the features you're interested in, such as blur, window previews, and window switching.

Building modern Desktop Ecosystem for UNIX-like Systems with Rust and Wayland.
Hello! I would like to hear some suggestion and opinions from Rust community about building Wayland ecosystem in Rust based around Smithay and their Client Toolkit. I'm working with Wayland Compositors for over 2 years now (private projects) and wanted to move ahead from C++ to build modern Desktop Ecosystem and it's components (truly unique, not copies of macOS or Windows styles) like notification daemon, customizable desktop shell or powerful wallpaper daemon for any compositor which implements layershell protocol. Current idea is to create wallpaper daemon which uses WGPU to render shaders, images or gifs with comfort of high perofrmance renderer (still learning wgpu and it's slow process). For UI components I would like to use truly amazing KayakUI create which uses JSX-style syntax for designing widgets. Desktop Shell should provide plugins (most likely applied through WASM) for integrating various creates to get e.g. weather info or compositor integration etc.
