Or using .ssh/config since entries in there act like hostnames: # ~/.ssh/config Host github_ssh HostName github.com User git IdentityFile ~/.ssh/my_github_key > git remote add gith…

Reminds me of https://goshdarnfunctionpointers.com/ which has helped in some cases.

Isn't there `proc` on Linux systems? Get the pid of the process you want to inspect, and while its running, execute `ls -lh /proc/ /fd/`. It will list the open file descriptors for…

One could use `printf 'first\0second'` in the Bash shell as an example of making a "string" with null embedded into it, but you can't store that in a Bash variable. $ TEST_VAR="$(p…

Similarly, I have a somewhat simple demo made for my website that is C++/Emscripten/Raylib. It's open source (MIT License) and you can grok the code here https://git.seodisparate.c…

https://choosealicense.com/ is a good resource that lists a bunch of licenses explained.

I made a C++ project[1] (using OpenCL and blue noise) to generate dithered images/video for a course project (the course taught how to program for the GPU). If anyone wants to just…

You can use a GPG key stored on a YubiKey with openssh, but with some caveats: 1. gpg-agent must act as your ssh-agent (which means ssh-agent should be disabled and replaced by gpg…

[1] discusses firejail running as root: > For a server, the process exposed to the outside world runs as an unprivileged user (unbound or nobody). The process is started by a separ…

As a lightweight alternative to Docker-based (or any container-based) solutions: Try firejail. You can set up a directory that will be the "home" of the sandboxed application you'r…

Someone else on HN earlier posted their QR-code scanning Android app[1], which I've been using because it doesn't automatically follow URLs but displays the raw text of the QR code…

Is it too old-fashioned of me to prefer IRC? Discord has its place, but I favor IRC.

I use the `rustup` package instead of the `rust` package to manage a local installation of rust. This graph seems to show installations of the `rust` package, but I don't think tha…

Been using Linode since 2019. Service worked as expected (worked well), and I hope that won't change after this. If I had to move, I'd have to go through the pain of setting up my …

As someone with a C/C++ background, this gist was a good reference for those times I needed to use Javascript: https://gist.github.com/yig/8744917

Oh I see, thanks for the reply. I did a quick search and came upon https://blog.cloudflare.com/encrypted-client-hello/ which does shed light on ECH. Though I am not sure if only Cl…

Out of curiosity, I once used wireshark to examine packets from my own system which was configured to use DNS over HTTPS (using dnscrypt-proxy). I discovered that the hostname of t…

Redox-OS has a similar situation that kernel code should never panic https://gitlab.redox-os.org/redox-os/redox/blob/master/CONTR... . No possible panics should ever exist in kerne…

In Korean, the vowels ㅣ (ee sound) and ㅐ (eh sound) are different in the written language. There are actually more difficult things such as ㅐ and ㅔ (both "eh" sound) which can get …

So in Korean, the word for "you" is 니가 (pronounced "nee-gah"). Example usage: 니가 언제 먹었어요? (When did you eat? "Nee-gah un-jeh mug-uss-uh-yo") I can't help but wonder if the use of t…

Actually I have my desktop configured with an encrypted root. Turns out GRUB can actually decrypt the partition holding /boot before loading the grub.cfg. Though I have this set up…

"When stuck debugging, question all of your assumptions about the program." A shower thought. Helpful if the program does something other than what you thought it did, allowing you…
