@FBorsik @VintonGCerf @parracatholic It's like we've built another Great Library, and forgotten to waterproof the archive. And like all libraries, there's no way to know what will actually be important in the future!

Can AI build a production-ready REST API in Rust in just 7 minutes? 🦀🤖

In Episode 3, @herberticus uses OpenCode and a detailed ~100-line prompt to build a tested, Dockerized bookstore service.

→ Multi-crate architecture → Strongly typed IDs → Shared authentication middleware → Idempotent database migrations

Better instructions. Better architecture. More maintainable code.

[LibreQoS @LibreQoS]

See #WISPPlanner: https://t.co/pZ6Pk1PQXd and #LibreQoS v3 live at #WISPAPALOOZA by @WISPAnews - Booth 108!

​We’ll also be demonstrating LibreQoS v3, with a new architecture rewritten around #DPDK for substantially higher performance.

@giswqs What does this do that Quantum GIS (qgis) doesn't? Other than the AI?

[Herbert "TheBracket" Wolverson @herberticus]

@jhuffman42 @kamilskowron That wouldn't really be either language (Erlang was for stable telco systems, I loved using it there!), and in both languages it pays to know what you're doing (see DHH's basic errors in both).

[Herbert "TheBracket" Wolverson @herberticus]

@jhuffman42 @kamilskowron You can use both at once, and channels between the two. Works very well.
Otherwise, you need to be disciplined with spawn blocking (which literally sends your job to an actual thread pool).
An io-uring backend can also make a lot of io non-blocking.

[Herbert "TheBracket" Wolverson @herberticus]

@gwenshap Usually by finding that your architecture could be better, profiling, optimizing the hot loop - you know, the stuff that software developers have been doing for decades!

[Herbert "TheBracket" Wolverson @herberticus]

@davepl1968 So like most things involving intellectual property, I expect a very messy transition period to <something new>, whatever that may be!

[Herbert "TheBracket" Wolverson @herberticus]

@davepl1968 In many ways, it's "copyright laundering" - you put something through an LLM wash and hope that the result is unencumbered. It's going to be an interesting transition; we can't close Pandora's Box, but the implications from proprietary to GPL software are potentially huge.

[Herbert "TheBracket" Wolverson @herberticus]

@ImLunaHey @t3dotcodes I've typically setup a local model in opencode, and then pointed at it (I stopped using t3, but the harness is doing the talking to the model host anyway - t3 is just outputting the conversation and maybe doing orchestration).

[Herbert "TheBracket" Wolverson @herberticus]

@namnium_01 Wow, that looks a lot like J2EE in Rust!

[Herbert "TheBracket" Wolverson @herberticus]

@itsalicesoul I was about 6 or 7. Your traditional 10 PRINT HELLO 20 GOTO 10 type thing

[polars data @DataPolars]

We just released Polars 2.0.

It removed many of our legacy decisions makes the streaming engine our default and promotes SQL to a first class citizen within Polars.

It comes with initial out-of-core (spill to disk) support, a new Map data type and a lot of performance improvements. In fact, we think Polars is now one of the fastest analytical SQL engines on a single node. See benchmarks in the post: https://t.co/ATc6UzJqby

[Herbert "TheBracket" Wolverson @herberticus]

@kamilskowron There's at least one Rust implementation of BEAM.
Actors in Rust are also really popular both channel based and networked, with varying levels of supervision (but usually not hot swapping).

[Herbert "TheBracket" Wolverson @herberticus]

@ScottShapiroUXD @ardanlabs From experimenting while I put this together, the engine choice remained the same unless I explicitly specified one. Single player support never appeared unless requested. I didn't check if other models prefer a different base engine.

[Ardan Labs @ardanlabs]

Can you just build things with AI agents? 🕹️🦀

In Episode 2, @herberticus puts it to the test by building Pong in Rust with two different approaches:
→ 1-line prompt vs. 19-line engineered prompt
→ Macroquad vs. Bevy
→ Debugging with AI agents
→ Code quality and modularity
→ The “genie problem” with ambiguous prompts

AI can write the code. Engineering knowledge still shapes the result.

@lazysloth @GregMolnar Thank you!

[Herbert "TheBracket" Wolverson @herberticus]

As much as I hate quoting DHH, the results only surprised me in that Go should have done a little better. Presumably he didn't read the code for any of the languages. Rust is (almost) always a good performance choice.

[DHH @dhh]

I've had agents implement and optimize the Campfire web app in Elixir, Go, and Rust. Yes, Ruby is the slowest. I didn't care about that when the pay-off was huge in terms of productivity and developer joy. But if you're no longer reading the code? https://t.co/MM4yFETaI3

[Herbert "TheBracket" Wolverson @herberticus]

@GregMolnar Depending upon what you're doing, I agree!

[Herbert "TheBracket" Wolverson @herberticus]

@GregMolnar I'm part of the crazy community, I love it! (Author of 3 Rust books, Rust trainer at Ardan Labs)

It's really only slow development while you get used to it (I was a c++ dev for decades before).
