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.
sbctl
- Show HN: Sbctl – Secure Boot key manager

Show HN: SSH-tpm-agent – SSH agent for TPMs
No, this isn't true nor correct.
Secure Boot and TPM do offer tangible security benefits and is security features you can take ownership of.
Secure Boot allows your own key hierarchy, and TPM allows you to take ownership.
The linked boot disk isn't really proof that Secure Boot is useless. If you don't set a MOKManager password (as you should), and you change the security state of the machine while present at the keyboard. Yes you can boot things.
This is intended to make sure people can actually decide to trust things. And having insecure defaults makes this less useful. Not very surprising.
TPMs could also prevent attacks like this on your machine.
Incidentally I've invested quite a bit of time in making user-friendly Secure Boot tooling as well. https://github.com/Foxboron/sbctl

Enabling secure boot for your Arch installation is very easy now with the "sbctl" tool
No problem! The sbctl package ships with a pretty extensive hook out of the box (https://github.com/Foxboron/sbctl/blob/master/contrib/pacman/ZZ-sbctl.hook). It's been very reliable for automatically resigning .efi executables after updates for me.

sbctl fails to find EFI system partition
sbctl verify returns failed to find EFI system partition despite it definitely is there. It's the same issue as this but remounting or restarting doesn't fix it.

[Kinoite/Silverblue]Decrypt LUKS volumes with a TPM on Fedora 35+
sudo dnf install asciidoc golang -y VERSION=0.11 cd /tmp curl -L "https://github.com/Foxboron/sbctl/releases/download/${VERSION}/sbctl-${VERSION}.tar.gz" | tar zxvf - cd "sbctl-${VERSION}" make sudo make install cd ~

Setting up secure boot while dual booting Windows 11 and Arch Linux
By far the easiest is to use sbctl to generate, install and use keys to sign your efi images. You can use mkinitcpio to build the unified kernels automatically and a pacman trigger to rerun the sbctl signing when the kernel is updated. Pretty straightforward (once you've done it once).

Intel OEM Private Key Leak: A Blow to UEFI Secure Boot Security
The question is whether you have any UEFI drivers or not. If they're in the ESP you can just look there to check, but UEFI drivers can also be loaded from PCI cards or baked in the firmware itself.
If you're using a TPM for Secure Boot, you can use the command in https://github.com/Foxboron/sbctl/wiki/FAQ#option-rom to know for sure.

- Linux Facial Recognition:
- Budibase, a GUI for building apps on top of SQL, REST, Google Sheets, and open-source alternative to Airtable and Retool, now ships with a 👥 Multiplayer Collaboration, 🤖 Autocomplete Bindings, 🔄 and Synchronous Automations.
- Lenovo Thinkpad e14 Gen 4 AMD?
- The things that I wish GNOME had integrated by default
-
Love the stability
you can even use facial recognition with IR webcam

I have a LG gram 16 2 in 1. Does anyone know how well this machine takes to Linux?

Is linux-surface kernel necessary when installing fedora 37 on WSLG2?
I just bought a go 2 (not laptop go) this weekend and installed fedora 37 on it. Almost everything worked without the surface kernel except the camera requires v4l2loopback kernel drivers to create a gstreamer device for apps that don’t support libcamera. There were only old versions available in copr but no surface kernel headers available so I couldn’t build the kernel modules. I switched to ubuntu 22.10 and got similar hardware support but more available packages. I’m still trying to figure out how to get the IR sensors to work so I can use howdy for login/sudo. https://github.com/boltgolt/howdy

Facial Recognition
First, you'll need to install Howdy.

when will PopOS support face id logins?
I've tried using Howdy, but that doesn't seem to work. It's probably because of this issue
-
Webcam very poor quality
Just like with digicams, it is not just about the sensor, but also the image processing itself. Should we omit the IR sensor to replace it with a better firmware-based noise-reduction system? But what about "Howdy" / "Hello" users, if we go this route?
What are some alternatives?
mortar - Framework to join Linux's physical security bricks.
fingerprint-gui - Use fingerprint readers with a Linux desktop environment
mkinitcpio - Arch Linux initramfs generation tools (read-only mirror)
slimbookface - Slimbook Face is an application that allows you to graphically manage multiple faces with boltgolt/howdy and enable PAM authentication throughout the system, or disable it at login, since login fails in some distributions or desktop environments (like KDE).
zorin-exec-guard - Zorin Exec Guard shows a warning when attempting to run unknown Linux or Windows executables and offers more trusted alternatives.
arch-linux-surface - Arch Linux kernel patcher for Surface devices
cryptboot - Encrypted boot partition manager with UEFI Secure Boot support
linux-enable-ir-emitter - Provides support for infrared cameras that are not directly enabled out-of-the box.
mainline - Install mainline kernel packages from kernel.ubuntu.com
rtw89 - Driver for Realtek 8852AE, an 802.11ax device
