just discovered `set -x` which activates debug mode and prints the expanded command before executing, that way enviro variables and aliases are unwrap.

i had some crazy networking issues while trying to run talos linux using docker on my local machine.
the first one was loss of internet connection on the host a few moments after the cluster creation process starts.
by changing the subnet to a different cidr i was able to overcome the issue

this year the goal is to play with technology, first one i’m trying is Talos, which is a Kubernetes OS. so far i‘m very impressed.

rust generics are very powerful:
trait Mystic<T> {
fn mystify(_: T);
}
impl<T, U> Mystify<T> for U {
fn mystify(v: &T) {
// details
}
}
and have mystify(T) available in all your types and the ones from the std lib and to also be able to pass any type to the function is insane.

fn mystify(_: T);

me coming from golang trying to write rust:
fn bs(n: *Vec<i32>)
the compiler screams at me because i’m an heretic.
it still feels weird declaring a function as if i’m getting a reference for an already existing value:
fn bs(n: &Vec<i32>)
fn bs(n: *Vec<i32>)
the compiler screams at me because i’m an heretic.

SNI is a genius idea. My mind was struggling to answer how can we do routing based on hostnames if everything is supposedly encrypted in TLS communication.
Turns out, some people thought of a solution a long time ago. Just beautiful.

What is SNI? How TLS server name indication works
SNI, or Server Name Indication, is an extension for the TLS protocol to indicate a hostname in the TLS handshake. Learn more about the TLS SNI extension.

It is funny to me that a 300 page book doesn't seem so big as it used to be the case for me in the past. After reading a few thousand plus books, I feel like I'm about to read a 30 page essay when I see 200/300 pages.

On X you will sometimes see people complaining about Rust binaries being large compared to the C ones.
This is not new. When Unix was re-written to C in 1973 its size increase by about 1/3, but the authors claimed that the benefits far outweighed this increase in size.

How does a video player work? You start with an encoded video file, download tiny chunks of audio and video, decode them then push them to the rendering buffer to display them
Sounds simple, except when trying to share data mutably across threads
Why? 🧵 👇
