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.

Show HN: Multi-monitor KVM using just a USB switch
With my COVID obsession of live streaming while writing code, I ended up building something a little more elaborate. https://github.com/timgws/kvm-switch
It doesn't use DDC commands direct to the monitor(s), instead swapping it for a HDMI matrix combined with a traditional KVM for swapping around inputs smoothly when you roll your mouse over the edge of different operating systems.
The switching client runs on Windows, MacOS and Linux (if you use X).

Displayport: A Better Video Interface
I had the same issue with this device. I ended up writing some code that you could run on a machine to operate the switching via the RS232 port: https://github.com/timgws/kvm-switch/
Bonus for adding 'glide and switch' functionality, so you can move the mouse to the edge of the screen and it would jump the input to the next display in your layout. It's like a hardware version of Synergy.
Very finicky device, but if you don't touch it - and you don't use any of the shortcuts - it works.

Ask HN: What is something you built but never marketed?
The proverb 'necessity is the mother of invention' made me build a solution for sharing a keyboard and mouse between multiple devices.
Synergy/Barrier is not horrible, but I find the latency a little painful.
Ended up getting an industrial HDMI switch, with a KVM. Built a server in Go that connects to the serial port of all the devices.
A companion client that runs on all the machines tells the server when the mouse moves to the edge of the screen, so the USB inputs can be switched to the correct computer. Basically, it allows you to have multiple computers connected, to multiple displays, sharing one keyboard and mouse. (You can define layouts on the server, so the displays can move around on the matrix HDMI switcher).

Is there specific hardware to make passthrough GPU easier?
Alternatively enable vGPU for the 2070 and use it for both Jellyfin LXC and Windows VM. https://github.com/DualCoder/vgpu_unlock

GPU virtualization?
I'm on Linux and I'm running a 3070 Ti (Nvidia). I have always wanted to do GPU virtualization but because NVIDIA won't release vGPU for consumer card no one can do it without crossing legal red tape or problems with bricking your GPU. I did find this [https://github.com/jamesstringerparsec/Easy-GPU-PV] however it is only for windows, I found this [https://github.com/Arc-Compute/LibVF.IO/] and does not work with my GPU, and this [https://github.com/DualCoder/vgpu_unlock] and can't get it to work. Done any one know an alternative on Linux that work just like this, overcoming these problems (on KVM)?

GPU pass-through/Sharing between multiple VMs
Otherwise, your only other option is the real hardware virtualization options that are available. NVIDIA's enterprise vGPU solution is for expensive compute cards however some have had good luck making vGPUs work on consumer NVIDIA cards with tools such as vgpu_unlock
