Nim Conf 2026 (Online, Sat June 20)

I am pretty sure the general quality will be good and there will be hidden pearls (last year pearl for me was the one about putting Nim on e-ink screens all over the house)

Did Nim 3 go all-in on compile time memory management?

pietroppeter3• 1 month ago

AFAIK main focus of Nim 3 is about incremental compilation and enabling better developer tooling bringing in innovations experimented in Nimony (key is NIF intermediate format).

The new compile time memory mgmt was the focus of Nim 2 (it is possible there are still improvements)

My love letter video turned out a bit chaotic, I apologize upfront.

But the core points I make there I can get behind any day of a week. I do think Nim is the best language out there and I'm tired of pretending it isn't (insert the DeNiro-Phoenix-Joker meme here :-)

It's a bit sad, but do most even care about elegant and efficient code these days in the age of coding agents?

shevy-java• 1 month ago

Coding agents do not affect me at all, meaning, I don't care about them. I think this is also the case for some other developers.

Having said that, though, this assumes that xyz is great - or was great already - before coding agents. The team around Nim is great, and nim is not inelegant, but you kind of need to want to like types, and I found that to be the biggest obstacle for entry (also for crystal, by the way; the "just ruby, but with types" is IMO an incorrect description - just simulating syntax does not mean you are having the same language. This is even more so not the case with elixir. Some people think ruby is solely or primarily ruby because of the syntax. This is wrong; it is the philosophy that is the main difference between e. g. ruby and crystal or ruby and elixir, not the syntax; syntax comes after the philosophy and the philosophy is very different, though admittedly in crystal it is closer to ruby's philosophy than elixir's philosophy is to ruby's philosophy). I kind of like having to not want to care about types at all. This is also why I think those who want to slap on types on ruby and python are wrong. They use their own biased mindset to project from this point on, how languages without types are useless. And you can not convince them otherwise - they have set up their brain to function only that way already, which is interesting (and explains why they are so desperately trying to add types to e. g. ruby and python, as an example).

This may seem like a modern conflict, but what I like about your post is its more general human cognitive orientation. Since to each new generation everything is new, people tend to forget that this kind of tension goes back to the dawn of programming with Fortran and Lisp, or even earlier if you count various notations for math.

FWIW, CPUs/hardware structurally do not have quite as much luxury for dynamism/monotyped things. So, all this does connect with how tight/abstract a bridge to the hardware world one cares about (which just varies). That naturally connects to performance, but that also becomes tricky once one moves to pragmatic problem decomposition over purity (e.g. NOT "pure" Python or "pure" Ruby). In my experience, people tend to overvalue purity as much as they tend to over-simplify. :-)

Some of us are still writing code.

A lot of it depends on what kind of company / industry you work in. For example, in Rust space there's big divide between LLM-heavy users and light/no-LLM users. Main rust repositories: the language, standard library, formatter, linter, LSP - all forbid LLM-generated code, and lots of third-party libraries, especially low-level and security related, follow suit. However, application code written in Rust is often LLM generated. So, if you work with Rust and you contribute to core Rust projects you have to write a large portion of the code yourself.

But when I talk to my friends who work with TypeScript it seems like they all moved to LLM-generated coding full-time.

Last I saw, the LLM policy for the Rust project was under discussion, and it did not ban all LLM related code.

The Nim compiler is now also slopcoded.

moigagoo3• 1 month ago

No it's not. Araq does use LLM to generate code in Nimony but his approach involves very strict control over the produced code, it's nothing like Bun's Zig to Rust endeavor where they just asked it to dk the migration and it produced a million lines of incomprehensible code. Calling it slopcoding is a misnomer.

vips7L• 1 month ago

My coworkers never cared about this even before the age of slop.

theSherwood• 1 month ago

FYI, there appear to be several typos where occurrences of "h" seem to have been replaced with "d", such as in "tde".

digdugdirk• 1 month ago

It took me way too long to realize that "Nim for tde" wasn't referring to some obscure system...

For those new to the topic and less patient than "full conference" levels of attention, it doesn't cover things like UFCS/command-call, user-defined operators, or many other details, but for its incredibly short run-time, this video might give you a tiny taste of the flavor: https://www.youtube.com/watch?v=WHyOHQ_GkNo

jlokier• 1 month ago

Any ideas why Nim seems missing from job and contract boards? Although it's niche, it doesn't seem that obscure compared with countless other niche things I see advertised.

I really enjoyed programming in Nim professionally, and got to know it well. But I've literally never seen a job ad which mentions Nim since then, except at the company I already left (Status), so that's not really an option.

After realising there's no work in it, I struggled to justify using Nim in new projects including personal projects, even though I like the language.

If anyone's reading this and looking to hire someone who knows (or rather, knew) Nim well enough to do quite advanced work in it and doesn't need training, please do drop me a line :-)
