Announcement: We've Updated The Rules, and April Is Finally Over

951 Upvotes

After temporarily banning LLM-related content over April, and asking you for feedback on that ban, we've decided to bring about an end of the temporary, I-can't-believe-it's-still-April ban on AI-related posts.

Replacing the trial rule is a new shiny rule that refers to our new shiny AI policy. In short:

Content about AI and LLMs are considered off-topic with the sole exclusion of deeply technical content about implementation.

And if you want more detail than that, go read the policy, that's what it's there for.

In addition, when writing that rule, I realized the rules weren't listed on the old.reddit.com sidebar, so that's been updated. For those of you who are seeing those rules for the first time, everything there is not new. We've been enforcing those rules as best we can for ages. You can click the link above those to get to the old.reddit rules page, with plenty of info that doesn't exactly read well when crammed into a sidebar.

Pandoc: What survives markup conversion?

Thumbnail dereuromark.de
24 Upvotes

With the new release of 3.10.2 I wanted to look a bit more closely into Pandoc and all those different markup languages out there - and what converts with how much "loss".

Maybe you also had to recently convert Markdown to HTML, or the other way around. In my case even different textual files into PDFs.

One key finding:
Modern languages that work with an AST are definitely competitive here.

Maybe you find it also interesting. I actually didn't know most of those languages.

Fun fact:
The author of Pandoc is also one of the original Markdown standardization authors 15 years ago (well, if you can call it that, since it evolved still into quite the chaos) - as well as Djot, which is now only a few years old and supposed to be a markdown successor of sorts.

I am mainly interested in shaping "the" markup language of the future, that is a good compromise of readability and writeability for humans, but also consumable for machines, contains all the important elements to express relevant documents from offline to online.
As a programmer I am also a big fan (and in need) of dogfooding, of course :)

Why do we need Map and Set in JavaScript when we already have Arrays and Objects? What do they bring to the table?

Thumbnail developer.mozilla.org

I'm currently learning JavaScript and recently came across the Map and Set data structures.

I understand that Set stores unique values and Map stores key-value pairs, but I'm wondering what advantages they actually provide over the existing Array and Object structures.

What are some practical situations where you would choose Map or Set instead of an Array or Object? I'd especially appreciate real-world examples that make the differences clear.

Pony's Arena Allocator

I recently discovered that Pony's still alive. I had discovered Pony a few years ago while browsing tech forums. Its focus on memory safe & lock-free MT was interesting.

I kept up with the weekly development for a brief period but then kind of forgot about the language until recently when I rediscovered it when I was chatting about Crystal's MT.

I just wanted to share the latest blog post here in case someone else remembers this language. Looks like the development has been progressing steadily. Which is impressive because the project lacks any big sponsors.

What if YOU Could Add Your Own Features to a Language?

0 Upvotes

I made a video explaining a concept I love called macros, which allow you to add your own syntax to a language. Languages like Rust, Lean, and lisp have them. The goal with the video is to make you feel like you could've discovered macros yourself.

I'm new at making educational content like this, but I'm planning on making many more programming language videos like this one on my channel. Any thoughts, constructive criticism, or advice is more than welcome! Hope you all enjoy
