Day 2: Cube Conundrum...

I’m a bit late to the party for day 2. Here’s my answer:

🎄 - 2023 DAY 1 SOLUTIONS -🎄

Welcome everyone to the 2023 advent of code! Thank you all for stopping by and participating in it in programming.dev whether youre new to the event or doing it again....

CannotSleep420, 5 months ago

I finally got my solutions done. I used rust. I feel like 114 lines (not including empty lines or driver code) for both solutions is pretty decent. If lemmy’s code blocks are hard to read, I also put my solutions on github.

One small thing that would make it easier to read would be to use (I don’t know what the syntax is called) as opposed to the magic numbers for getting the ascii code for a character as a u8, e.g. b’0’ instead of 48.

How will you be tackling the challenges this year?

What language(s) will you be using? Will you be trying anything different this year to usual?

CannotSleep420, 5 months ago

I’m using rust. I’m hoping I’ll be able to finish all the days unlike last year.

Lemmy.ml `v0.19` upgrade issues and downtime.

In anticipation of Lemmy’s upcoming 0.19 release, and to work out any final issues, we’re going to deploy a test release on lemmy.ml within the next few days....

CannotSleep420, 5 months ago

Some that come to mind:

Scaled sort, which takes community size into consideration when looking for top posts

User will be able to block instances without the need for their home instance to defederate

The new flow for enabling 2FA makes it harder for users to accidentally lock themselves out of their accounts

There will be a feed option to just see posts in communities you moderate (as opposed to subscribed, local, and all)

Controversial sort

You can import and export account settings as JSON, making switching instances easier

I’ve been trying to find a good Marxist instance, but Lemmygrad and Hexbear are widely hated. Why is that? Are there any good leftist instances?

is there a universal translator for Lemmy? (lemmy.dbzer0.com)

I find myself blocking a lot of foreign communities just because they’re foreign. It feels wrong and unnecessary. This is the future isn’t it?...

why do lemmy users hate the use of emojis ?

I’m a heavy emoji user, texting is such a poor medium for communication, many times people get the wrong message, but with an emoji you’ll get an idea of the face I’m making, so less chance of misunderstanding...

FlorisBoard | FOSS keyboard that respects your privacy (florisboard.org)
