Funny story

So I was just starting out with linux today, I dual booted kali and ubuntu on one ssd with windows on another, however, try as I might, I could not get my tethered usb connection to my phone to be stable. After attempting a numerous amount of fixes and solutions, I fixed everything by moving the usb cable from one of the front ports to one of the back ports of my pc. I was almost about to give up, but luckily found a situation.

What options Linux have for Memory Isolation?

Many years ago in 2012, I was studying QNX in college and we saw a lot of advantages of it. One in particular was memory isolation and dedicate CPU. Now, I was studying TEE (Intel SGX) and I understand one of the advantages is memory isolation, something that I understood QNX solved long time ago now could be possible in Linux only by using specialized secure hardware.

I saw this as a negative aspect of Linux, secure research is aware that whatever process with privileges can hack other process by accessing its memory. I am not sure if QNX solution is 100% trusted, but I want to know fi Linux is doing something or considering something for this problem.

Only the Tip (ghostty)

PSA - Only the tip version of ghostty requires zig 0.14 to compile, everything else requires the older zig version 0.13. This can be slightly confusing with the new documentation saying simply that zig version 0.14 is required (yes, but only for the tip).

When in doubt use the full path to the desired zig binary when compiling (or simply download the compiled ghostty binary instead).

My little cheat sheet, csv style:

"ghostty version", "zig version required"
"v1.1.0", "v0.13"
"v1.1.2", "v0.13"
"v1.1.3", "v0.13"
"tip", "v0.14"

>Note: I feel like ghostty version 1.1.4 must be coming soon and that will probably require zig 0.14 to compile, similar to current tip.

In unrelated news (since it happens to be in the screenshot), PowerShell version 7.5.1 is available now! Totally unrelated to ghostty but it looks like they do have support for PowerShell on the roadmap.


//Edit: fixed version numbers that I butchered.

Is Kernotex a good LFS resource?

This playlist by Kernotex, is it good for learning LFS https://www.youtube.com/playlist?list=PLyc5xVO2uDsB9d49xOfLDObv9O0a0G6kH ?


Yes, I will also have the book itself by my side and read it but having someone to do the steps with you makes it less intimidating.

Do you restrict your SSH with PubkeyAcceptedAlgorithms?

As per the noscript, I wonder if it's common practice to change the defaults (see below) and if you do, what do you typically end up with?

From man 5 sshd_config:

PubkeyAcceptedAlgorithms
Specifies the signature algorithms that will be accepted
for public key authentication as a list of comma-separated
patterns. Alternately if the specified list begins with a
‘+’ character, then the specified algorithms will be
appended to the default set instead of replacing them. If
the specified list begins with a ‘-’ character, then the
specified algorithms (including wildcards) will be removed
from the default set instead of replacing them. If the
specified list begins with a ‘^’ character, then the
specified algorithms will be placed at the head of the
default set. The default for this option is:

ssh-ed25519-cert-v01@openssh.com,
ecdsa-sha2-nistp256-cert-v01@openssh.com,
ecdsa-sha2-nistp384-cert-v01@openssh.com,
ecdsa-sha2-nistp521-cert-v01@openssh.com,
sk-ssh-ed25519-cert-v01@openssh.com,
sk-ecdsa-sha2-nistp256-cert-v01@openssh.com,
rsa-sha2-512-cert-v01@openssh.com,
rsa-sha2-256-cert-v01@openssh.com,
ssh-ed25519,
ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,
sk-ssh-ed25519@openssh.com,
sk-ecdsa-sha2-nistp256@openssh.com,
rsa-sha2-512,rsa-sha2-256

The list of available signature algorithms may also be
obtained using "ssh -Q PubkeyAcceptedAlgorithms".

Linux Troubleshooting - a compendium of information on issues and how to fix them

Hello everyone!

I'm working on a new project, in the shape of a Github repo to make, over time, a massive database on issues people have on Linux and how to fix them (when they're not just some random bug) or sharing workarounds. Feel free to use the knowledge I'm already putting in there and add some yourselves following instructions on the readme - the more people using it, the more effective it will become at solving people's pains with Linux.
