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.

Does anyone know why Rufus creates a second "UEFI" volume that's <1MB?
Indeed, that 1 MB volume is the UEFI:NTFS partition that is described here.

MSI's (In)Secure Boot
> Can you please link me some articles/references?
Well explained here: https://gabrielsieben.tech/2022/07/29/remote-assertion-is-co...
So the issue is not the SecureBoot itself, but the ways it can and has been and will be leveraged against the user. If a desktop computer example is not enough, look at how Android phones have increasingly tightened down everything. You can't just take any model and install a custom OS (aka ROM in Android community). It was universally easy 10 years ago, that's why Cyanogenmod became so popular. Now your choices are very limited.
> \> > But that is besides the fact that these acts of aggression
A great thread and arguments provided here, how Microsoft (who love open source, according to own PR) will not sign anything GPLv3 for SecureBoot: https://github.com/pbatard/uefi-ntfs/issues/20#issuecomment-...
Microsoft has the defacto monopoly over the signature process, because nobody embeds any CAs in UEFI except for Microsoft's. What would be a user-friendly way? To preload UEFI with major Linux distros' keys, disabled by default, with an easy first-time setup menu to select what to do.
My laptop came with SecureBoot enabled by default although being "OS: FreeDOS" on paper. I had to figure out to disable it to boot into a live distro else it fell into an EFI shell.

> ... I am much more concerned about Intel ME and AMD PSP, where's the outrage about that?
With this I just want to say the wallet argument doesn't work when something slowly becomes the status quo and it takes experts/activists to fight back (a minority by numbers).
> I still can't easily utilise a TPM [...] and nobody bothered to integrate the functionality?
I agree, I'd have liked to enforce SecureBoot post-installation but it is too much hassle for me, I think only RedHat made good improvements in this area where it's actually easily usable (auto signing the kernel image etc.)
> Security isn't about what's unlikely, it's about the entire chain.
... But if I followed through, then still the weakest point is/becomes the keyboard. It would be trivial for an evil maid to add a keylogging device between your desktop and the physical keyboard. Do you check the rear IO on each boot? The considerations differ for laptops where you can't just plug something inbetween and need to disassemble it (time required: over night or airport luggage).

Windows 10 ISO with a large WIM - can’t boot

Looking for help installing a specific distro on a very peculiar computer.
I am the developer of Rufus, and I have spent an inordinate amount of time making sure that, YES, EVEN UEFI COMPUTERS THAT ARE "ALLEGEDLY" ONLY MEANT TO SUPPORT FAT32 FOR BOOT CAN ACTUALLY BOOT FROM THE NTFS PARTITION CREATED BY RUFUS (through the magic of a little solution called UEFI:NTFS). See also this entry from our FAQ.

Rufus made 2 UEFI partitions. Which one to choose?
For more details about the second UEFI:NTFS partition, see https://github.com/pbatard/uefi-ntfs.

I made a USB for Build 25120 with Rufus and for some reason it is also displaying the UEFI partition for it. It is meant to happen?
Rufus dev here. That's the UEFI:NTFS partition, needed to boot computers that don't have a native NTFS driver and it is completely harmless (and uses a negligible amount of space since it's just 1 MB). So, yes, this is meant to happen.

Anyone able to install windows on steam deck while only owning a mac?
So if you want to copy the contents of the ISO as is, you need to extract them to exFAT or NTFS (which are file systems that the Windows installer can also read outside of FAT), but this means that you may have to install an exFAT or NTFS UEFI driver to chain load the Windows installer, which is why utilities like Rufus and WoeUSB add a 1 MB UEFI:NTFS partition at the end of the drive, that takes care of that.

Can't get Windows 11 image to boot.
Rufus uses UEFI:NTFS, and therefore WILL allow your firmware to boot from NTFS. So, no, you don't have to use FAT32, and you should let Rufus create the drive with NTFS, as, even when using NTFS, it will create a drive that can be booted from UEFI.

[Discussion] Tool to burn in USB a standalone media created in SCCM
If it's because Rufus creates 2 partitions, then you should read about this (UEFI:NTFS is what Rufus uses to boot drives that are NOT compatible with UEFI, such as ones where you cannot use FAT32 because they contain a file that is larger than 4 GB), and understand that the data on the NTFS partition is exactly the same as the one you'd have found on a FAT32 drive, if your data was suitable for FAT32.

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.

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.
