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.

Building Flexible, Low-Cost Wireless Access Networks with Magma
I recommend to have a quick look at https://github.com/magma/magma#readme first to get a quick overview of what Magma is, before going into the details.
- Is there any technical limitation preventing existing miners upgrading to 5G?

Cisco virtualised packet core
There are also open source software stacks, such as Magma https://www.magmacore.org/

AWS Private 5G- 5G As a Service
Are they using Magma[1]? I couldn't tell from their sparse FAQ[2]. The Magma community is strong and they're making great progress on the open standard.

CEO Mark Zuckerberg responds to the massive Facebook document dump
uhhhh I realize hating Facebook is cool, but Facebook is just a contributor to Magma which is open source platform with many partners: https://github.com/magma/magma

Facebook open-sourcing a more precise time server
PTP is required in a number of 5G implementations. Facebook's 5G core (Magma - https://github.com/magma/magma) utilizes it quite a bit.

Meta's Reality Labs lost $3.99 billion last year, bringing its total losses since 2020 to $30 billion
Even just specific projects under that have been impactful. For example the open time server project.
- What’s the most granular magnitude of time (Picosecond, Femtosecond, etc.) that a CPU can return when it’s queried for system time?
-
New atomic clock loses only one second every 300B years
Facebooks Time Card is a good starting point if you want to start looking into how higher end timing devices are built: https://github.com/opencomputeproject/Time-Appliance-Project...
Afaik its not currently available for purchase, so it is more of a diy route. If you want a standalone unit, it probably wouldn't be too big of hassle to ducktape that Time Card to e.g. Raspberry Pi CM4 or similar module with pcie and drive a display (or whatev) that way. Or that FPGA on the Time Card probably has enough spare capacity to do it directly too, for a simplified architecture (and maybe better hard realtime control).

Host your own Stratum 1 NTP (network time protocol) server using a $12 USD USB GPS to keep all your other servers synchronized
Now you can get/build your own atomic pcie clock for ~$300-2000 for your rack!

Time Card
Time Card is an open-source solution for PTP-enabled networks that provides the accurate time via GNSS—with a high stability (and holdover) oscillator such as an atomic clock as a backup in the event of GNSS failure. zeroibis recommends it for those who "need to go the full self-hosted NTP route."

Facebook open-sourcing a more precise time server
Really nice of them to release this. However, unless I'm missing something, the HDL for the FPGA on the Time Card is not part of the release. It looks like it uses a proprietary IP core from NetTimeLogic
https://github.com/opencomputeproject/Time-Appliance-Project...
They do include FPGA bit streams, but it's disingenuous to claim a fully open source release.
