From what I’ve read is not authentication bypass, it’s a RCE using certificates to deliver the payload. If a specific signature is found it runs the code that was sent in place of the signing public key. It also means that only someone who has the ability to generate that specific key signature could use the RCE.

There were some other bits that looked like they could have been placed to enable compromising other build systems in the future when they checked for xz support.

If filesystem UUIDs are IP equivalents. Then device paths are MAC addresses. FS labels are DNS. Device mapper entries are service discovery.

“Invalid” or “unparseable” are more understandable descriptors in normal language. I don’t think I ever heard of garbage/junk being used for that in language theory but it may be domain specific usage.

I’n Windows it is not stored in a keyring but instead in the registry. This has basically the same security threat model as a local key file.

The ssh-agent on Linux will do what you want with effectively the same security. The biggest difference being that it doesn’t run as a system service but instead runs in userspace which can make it easier to dump memory. There are some other agent services out there with additional security options but they don’t change the threat model much.

Initrd contains the systemd binary and enough libraries, services, and kernel modules to get booted this far. The system failed at switch root which is where the real root disk is mounted. Initrd can contain as much or as little as needed to get a working system which can be a lot of you are using a network filesystem as a root for instance.

My memory of the cp command is that attributes such as file times were transferred at the last step. I think this would make rsync safe in most situations where a system crash wasn’t involved.

If I’m reading it right I think the issue is using a HashSet to store the list of numbers for the sum. Some of the input numbers are repeated and the set discards them.

I could be wrong though as I only just started learning rust for AoC.

You can also use o1e as there are never more than a single shared character. It also doesn’t change the string size so it can be done in place. Still an ugly hack of a solution.

You don’t need to use big-O. You can calculate the full complexity in algebraic notation. It’s just a lot more work as you don’t get to discard terms.

I think I remember running into that as well but for whatever reason I couldn’t get accelerated-x working with the opengl libraries I was using for school. Likely the issue was just a lack of understanding on my part as I don’t think I had a good grasp of the Linux library loader until well after I graduated.

I’ve had a system in the late 90s with a 3dfx voodoo card. Also had a laptop with a SIS card from the early 2000 era.

The voodoo card was THE card to have it it’s day (mine was an older second hand system though). The SIS card… for some reason they decided that standard VESA mode probing wasn’t a thing they supported and would hardware crash when that API was used. I eventually got it working in Linux after patching xfree86 to not attempt probing when loading the VESA driver.

The expression syntax for the GNU find command is very powerful. I would expect that it is up to the task. If you don’t have the GNU find command with it’s extensions I could see how it’s would be difficult.

QEMU supports either spice, vnc or sdl graphics output. If you want to copy/paste you need to use spice and install the spice agent on the VM.

My steam deck also unlinks family libraries with almost every os update. It might be an issue of overzealous hardware validation but it could also just be a bug.

It’s very likely that your disk is failing.

dd if=/path/to/file.mkv of=/new/file/path.mkv conv=noerror,sync bs=4k

Should give you a file with just the damaged bits missing.

PTSD from the days long ago when X11 error log would fill up the disk when certain applications were used.

Are they on a local disk? Thunar doesn’t render any thumbnails for remote storage by default.

When rsync copying the active root I like to bind mount / to /mnt/root_fs first. This avoids the issue with needing to exclude folders with sub-mounts and will expose files to copy that might be hidden by the mounts.
