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.

How do I go about hosting a shared drive for both Windows and Linux
The TLDR is that you create the filesystem on Linux/Raspberry Pi. Then you "export" that file system via some software to remote computers. You can use Samba (https://www.samba.org/) to create CIFS shares which can be mounted by either Linux or Microsoft Windows devices. There are of course other software/protocols you can use to export the filesystems like NFS, iSCSI, CEPHFS, etc; but these are a bit more complicated than what a novice can deploy. I would start with Samba/CIFS and then branch out once you get more experienced.

Go SMB Server?
You could try to use samba via cgo.

Is there any r/rust library for "net use"?
I think you want a CIFS/SMB client? A quick search turned up smbc, which looks like it does what you want. All three crates are based on libsmbclient, which is a C implementation from the Samba project.

Major Linux Problems on the Desktop, 2022 edition
> First, the article doesn't say that "Linux is not ready for the desktop" - or concern itself with this as an abstract question.
Well, it does, but in a sarcastic manner:
"Yeah, let's consider Linux an OS ready for the desktop :-)."
> Also, I find the "GNU/Linux is already ready for the desktop; I and others use it" argument tired. I've used GNU/Linux for the desktop in 1998, but it sure as hell wasn't ready then.
Conversely, that it doesn't work for certain people does not mean that "it is not ready", which the post does state (sarcastically) as I pointed out above.
> Many use cases aside...
I'm not sure how the browsing, docs and email is miserable, maybe you can expand on that. The video editing is indeed a bit limited from my experience too. However, I don't think "limited proprietary options" is a problem. The community largely and specifically avoids proprietary software. Proprietary incursions into the community are generally seen as a negative thing. And for the lack of codecs, software patents for the most part are to blame.
And then it just comes to my original statement; many things stated in the article are non-issues to most Linux users or just falsehoods:
- Neither Mozilla Firefox nor Google Chrome use video decoding and output acceleration in Linux.
Firefox does.
- NVIDIA Optimus technology is a pain
NVIDIA is a pain.
- You don't play games, do you?
I do.
- Linux still has very few native AAA games.
So "it's not ready" because it doesn't have AAA games? What a pitty.
- To be fair you can now run thousands of Windows games through DirectX to Vulkan/OpenGL translation (Wine, Proton, Steam for Linux) but this incurs translation costs and decreases performance sometimes significantly.
No, not 'significantly' for dxvk.
- Also, anti-cheat protection usually doesn't work in Linux.
For good reason. Blame the dev, and don't make it work on Linux.
- Microsoft Office is not available for Linux
Thankfull.
- LibreOffice often has major troubles properly opening, rendering or saving documents created in Microsoft Office.
And whose fault is this? Use ODT.
- Several crucial Windows applications are not available under Linux.
Thankfully. Also, 'crucial' is subjective.
- In 2022 there's still no alternative to Windows Network File Sharing.
It's available since 1992: https://www.samba.org/
- Linux doesn't have a reliably working hassle-free fast native (directly mountable via the kernel; FUSE doesn't cut it) MTP implementation.
I can transfer files to my phone just fine.
- Too many things in Linux require manual configuration using text files.
No.
etc.

Get linux samba shares to show up in windows again
I have a media server that runs ubuntu, and today I wanted to copy some files off of it from my windows laptop. But the samba shares weren't showing up in file explorer (but they showed up on fine on my macbook).
