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.

Discussion Thread
I would follow the suggestions in https://github.com/mkj/dropbear/blob/master/DEVELOPING.md for Deubg Printing, as this seems difficult to solve within information from dropbear.

Adding Computer Tracking (GPS)
Heads is good reference for what could be done at BIOS level. It can connect via ethernet but only because the firmware is built in (The GBE section in IFD stands for Gigabit Ethernet). If you want an SSH server, this needs to be built separately because Dropbear is too big to include by default. Due to the size of firmware and range of different wifi cards that could be installed plus the software to connect, wifi is not possible in Heads. Similarly with Bluetooth. For cellar, the firmware, software and configuration would be needed to BIOS. There is also how no service/roaming would be indicated without any physical meter like LEDs (Ethernet has LEDs to show connection). It would also take time during the boot cycle to connect to a cellular service and would block booting the OS. That said, you could add a service at boot of your OS to do this and connect to something like a NextCloud Phone Tracker to do this.

tinyssh
While it is good to have another alternative, I think Dropbear SSH[1] is also being used very widely.

Host a Dev Environment on Render with VS Code and Tailscale
I need an SSH server. I try OpenSSH, but run into an issue when I attempt to log in. OpenSSH servers use privilege separation as a security measure. The OpenSSH subprocess that handles authentication runs as an unprivileged user with its root directory set to some safe location. The CAP_SYS_CHROOT capability is required to change the root directory for a process, but Render services run in unprivileged containers without this capability. I discover that there are other SSH servers, like dropbear, that don't do privilege separation. This is great because it's not necessary for my use case anyway. My SSH server will run as a non-root user and will only be available within the VPN.

SSD belonging to Euro-cloud Scaleway was stolen,then turned up on YouTube
That's what Dropbear is supposed to do, it can be included in the initramfs of a server: https://matt.ucc.asn.au/dropbear/dropbear.html
Disclaimer: I still didn't try it myself yet, but it's on my (too long) list of things to do.

Thinkpad W530 No GPU output
I downloaded the VGA ROM for my Thinkpad W530 for both the Intel IGPU and Nvidia Quadro K1000M using this and configured the build config to use them with the correct PCI ports (8086,0166 10de,0ffc). Everything works fine except the output for both the VGA and the mini DP port. Does anyone have any ideas of what I could be missing here?

Can i make full disk encryption more convenient or should i just use an encrypted home dir?
You may be interested in Heads, which is available on Purism laptops under the name PureBoot. Though this really needs a coreboot-capable machine, I think, and isn't something you can just add to your existing UEFI boot chain.

You don't need to encrypt anything to verify those images, you just need to sign them. See how Heads does this.

Live OS needs a new name, what should it be?
Unfortunately there is also the Heads secure firmware: https://osresearch.net/ as well. Otherwise my vote would go to Heads. Liive OS could be pretty hard to optimize in a search engine, they'll think it's misspelled. Could call it "Miles" and just never ack the reference...

verify secure flash
If you worried about malicious changes, there is the write lock protection feature in coreboot that prevents internal flashing. This would require you to flash externally whenever you want to update coreboot. If worried someone will also flash your BIOS externally, you may want to look into Heads
