About us

🤗 Thanks for joining our little instance here, located in Oregon. The idea is to have a fast, stable instance and allow users to subscribe to whatever content they want from here.

😎 We dont block any other instances. We will keep it that way unless it becomes a moderation problem.

🤠 We will be around for a very long time, so you dont have to worry about us shutting down the instance anytime soon. We like performance and stability in our servers, and will upgrade the instance when its needed.

🥹 Make sure to join a lot of remote communities to get a good feed going. How to do that is explained here.

Lemmy mobile apps

You should start using one of these ASAP since the web browser user interface is quite ugly, even with themes.

Should I file a bug report? 😀 (programming.dev)

TIL: Sweden had February 30 in 1712 https://en.wikipedia.org/wiki/1712_in_Sweden , so I decided to see how chrono handled that.

use chrono::TimeZone;
use chrono_tz::Europe::Stockholm;

fn main() {
    let feb30 =  Stockholm.ymd(1712,2,30);
    println!("Date: {:?}", feb30);
}

 target/debug/feb30
thread 'main' panicked at /home/snaggen/.cargo/registry/src/index.crates.io-6f17d22bba15001f/chrono-0.4.34/src/offset/mod.rs:252:40:
No such local time
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Result (as expected): Not well! 😄

I also tested Java with

ZonedDateTime feb30 = ZonedDateTime.of(1712,2,30, 0,0,0,0, ZoneId.of("Europe/Stockholm"));

with simmilar result

java.time.DateTimeException: Invalid date 'FEBRUARY 30'

So, lets take a minute of silence for all the programmers of history related software, may the spagetti monster have mercy on their souls.
