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 journey from beginning to end
For what it's worth, it is possible to desolder the old connector and solder on a new one. Per Framework's documentation, the connector is a AUSB0534-P203A61. While I was able to find the part on the manufacturer's website, I'm not sure of a way to order it as an individual (I couldn't find it on Digi-Key or Mouser for example).

Building a Cyber Deck for emulation
Might be on the pricier side, but the Framework laptop mainboard is available separately starting at $350 https://frame.work/products/mainboard as well as the battery https://frame.work/products/battery, and there's documentation with suggestions/designs on how to built around it for projects like this https://github.com/FrameworkComputer/Mainboard. Should have plenty of power for emulation and light pc gaming, as well as thunderbolt support for an egpu.

could I build a stand alone touchpad using the framework touchpad part?
Look like trackpad (TP?) is just IIC. https://github.com/FrameworkComputer/Mainboard/blob/main/Electrical/Mainboard_Interfaces_Schematic_11th_Gen.pdf

Framework in 2022: Year-in-review
We released a 3D printable Mainboard Case, and open sourced our Mainboard drawings and electrical documentation in a Github repository.

Hooking up a 17.3" screen to a framework?
The block diagram for the Tiger Lake mainboards says that the current displays and motherboards communicate over eDP 1.2 (is Alder Lake-P the same?), so I started by looking for 17.3" screens that communicate with eDP 1.2.

The Framework Laptop Chromebook Edition
One thing worth noting is that basically, even now (almost 10 months post announcement), almost no one has a 6000U laptop outs (a search on Amazon and Best Buy shows two 6800U laptop models total, one Asus and one Lenovo). Two niche vendors, XMG and Star Labs, have both publicly stated that they would have loved to have offered Ryzen 6000 laptops, but couldn't get any allotments. There are were also well documented chipset issues - even into the summer Lenovo and Asus talked about requiring firmware updates to enable their USB4 ports.
That being said, starting w/ Rembrandt, AMD now has full 40Gbps USB4 controllers built on-chip. I'm really looking forward to Ryzen 7040 because Phoenix looks great (Zen4 + RDNA3 on TSMC N4 - yes please) and hopefully USB4 support has matured enough on the AMD side that Framework is able to release something.
My understanding is that the I/O limitation is in the re-timers - currently the Framework uses 4X JHL8040R's (labeled as Burnside Bridge) directly connected to the iTBT: https://github.com/FrameworkComputer/Mainboard/blob/main/Ele... Apple used these for their first M1 MBAs as well: https://github.com/ThomasKaiser/Knowledge/blob/master/articl...
But both Apple and AMD are now using Kandou retimers:

Radxa Rock 5 ITX: 8-Core ARM Mini ITX Board with LPDDR5 RAM
tkaiser has some additional information from his initial testing at https://github.com/ThomasKaiser/Knowledge/blob/master/articl... if people are curious to know more, though it should be noted these were early release samples and as such, software/firmware isn't exactly perfect at the moment

Pihole is down on orangepi 3 LTS, Debian bullseye 3.0.8. Can no longer SSH, and my username and root login isn't being accepted. Whats going on??
"Armbian recommends A1 rated SD-Cards only now (A2 rated cards need yet lacking driver support and therefore show lower overall and especially random IO performance)."

Steam Deck Card reader supports only SD Specification 3.x
Yes and no, in this articleguy tests A1 and A2 cards and on non compatible reader some A2 cards are slower than A1 cards.

PSA: A MicroSD card guide that seems to be sorely needed
Some early A2 cards were implemented poorly and actually had worse IOPS than A1 cards, as they used a worse onboard controller in the hopes of the system making up for the deficiency. See here. Reputable large A2 cards no longer have this issue but it's still a minefield.
-
Don't get stuck with the wrong SD card.
In addition to this, the A2 standard requires hardware/driver support of Command Queuing and Write Caching, and without proper support A2 cards can and will perform worse than their A1 counterparts
