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.

A guide to setting up a cloud server network
- What server software or framework to use. Ideally, if you dont need too much vanilla features (world generation, all mobs & items implemented, etc), I'd use something lightweight that is not based off of the vanilla server software. There are a few projects like this on github, including: https://github.com/Minestom/Minestom , https://github.com/feather-rs/feather , https://github.com/KryptonMC/Krypton , https://github.com/df-mc/dragonfly (bedrock). Which one you use will probably depend mostly on your preference. - You will need a way to store data separate from the servers. A database like postgres should work. There are a lot of different databases tho!

What would you rewrite in Rust?
There has been some work... feather mc server and piston's hematite client This client also seems to be in active development: Leafish
- Minecraft - Rust Edition

But guys, if you had to choose?.....
There is the feather port of Minecraft server. Lacking a gui but the serve could easily reach parity with some community help

Handling minecraft-like worlds in a rusty way?
As far as your enum idea goes, I don't directly see a place for storing chunk data in an enum (in the way that you would with Some(T). But, totally OK to store your block types that way (as feather-rs does)

Feather: A Minecraft server implementation in Rust
The insight contributors chart is usually a good clue. It’s not perfect because it only shows the main branch configured in GitHub and some project haven’t merged to main in years.
Still, it’s good to see how many real contributors a project has, and how active they are over time.

In a similar vein, there is also a Rust-based Minecraft server implementation:

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.
