Project mention: High-severity vulnerabilities affect a wide range of Asus router models | news.ycombinator.com | 2024-06-17
Any way to tell if these issues affect the community-developed, third-party "Merlin" firmwares?

For the modern server/desktop and even laptop, that's also no bad thing. It is somewhat ridiculous that UEFI bioses, internally, still boot in 16-bit real mode and have to do all the steps your bios bootloader used to do to set up a 64-bit environment ready to go: https://github.com/tianocore/edk2/blob/edc6681206c1a8791981a..., https://github.com/tianocore/edk2/blob/edc6681206c1a8791981a..., https://github.com/tianocore/edk2/blob/edc6681206c1a8791981a...
Why not just start the CPU in "long mode", which is what everyone is using it for, in the first place?
These newer ARM processors support 32-bit code at EL0 only (userspace). That seems like a reasonable approach for x86 as well and the freebsd announcement has this to say:
> There is currently no plan to remove support for 32-bit binaries on 64-bit kernels.
So for the moment, you can run 32-bit applications just fine.

Project mention: Tutorial on how to increase your ping artificially the "right" way | /r/GlobalOffensive | 2023-12-11
From what i can find googling around i can see the RT-AX82U is supported by the AsusWRT Merlin firmware which is an alternative to the original router's firmware. Although the firmware for your particular router is not on the main page i did manage to find a fork of the firmware which specifies your model as supported: https://github.com/gnuton/asuswrt-merlin.ng/releases . That way you can access it from SSH and use the linux commands to add latency. Keep in mind that it depends on the processor your Router uses, it requires MIPS architecture which most likely your Router has :-)
