On the laptops I've used with pre-installed Windows (which I reinstalled), the license key was in ACPI table "MSDM". I assume Windows gets it from there automatically. You can extract the license key from Linux with: cat &#

Yeah, he built an MMU, which is possible for any 8-bit CPU with similar features - nice work but I don't see any previously unknown features.

Had a secure server room with a maglock with very few cardholders and forgot our cards a few times. We wired-up a CD-ROM drive to a server positioned so that it pressed the door unlock button on the wall when it was ejected, so someone cou

Specifically zfs-dkms + the stable kernel package ("linux") can often be an issue because I have seen the kernel version updated by Arch without ZFS support for that version (obviously not something that the Arch kernel package ma

Even without network logging, the hypervisor can still access the memory of the VM, parsing the kernel process and paging structures to read process memory, which can store transient logging information. Things like AMD SEV/SEV-ES are

Well, two hard drives in RAID-0 if you want to play it back in real-time without copying it first to faster storage, because a single SATA drive cannot sustain 597.2MB/sec. Unless your definition of "basic consumer external hard

AMD EPYC is already that, a SoC - there is no EPYC chipset. They all have 8x 16-lane multi-function interfaces, which can be configured to work as PCIe, xGMI (inter-socket communucation), or SATA, as well as built-in USB, eMMC, LPC, UART,

Yep - this is the VFS shadow copy extension for samba, works great! Actually it doesn't require ZFS, just a method to create snapshots and find them - example smb.conf : vfs objects = shadow_copy2 shadow:snapdir = /home

Use a filesystem that does end-to-end error detection and correction. I use ZFS on all of my USB drives (even "real" SATA and M.2 SSDs via adaptors) and it frequently finds checksum errors (and thanks to the design of ZFS, is abl
