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.

ToyDB: A Rust learning adventure, fun open-source project, and database learning resource for the community
This is great, but you might want to consider a different name. There's already a Rust project called ToyDB, and it's a distributed database with a Raft log, SQL, disk persistence, ACID transactions, etc. It's under active development (though the developer now works at Cockroach Labs), and has 5K stars on GitHub, so I think they have the right to the name.

Any ideas for resume
Build something you’d like to learn about. Things I’ve considered replicating: A distributed database (see https://github.com/erikgrinaker/toydb), an interpreter (crafting interpreters is a good book), a Ray tracer (http://raytracerchallenge.com/), an RPC compiler and framework, a simpler neural network framework ( https://github.com/pjreddie/darknet)…

Which software do you think would be essential for the RISC-V to be succesful ?
Hilariously, I was trying out ToyDB on the Lichee-RV recently. While it does compile and run the five-node example setup (and memory usage is surprisingly low, which is a plus considering the 0.5GB of RAM), performance is three orders of magnitude lower than on a desktop x86 PC. Some of that is due to just having a single core run 5 nodes, some is due to the lower clock speed and slower memory, and some is due to slower storage (SD card). I don't think that explains everything, so I may investigate that later.

Well I think if you could replicate this https://github.com/erikgrinaker/toydb anybody would hire you.

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.
