Instructions unclear, Claude just spent three days and millions of tokens rebuilding SLURM from the ground up. /s
lukax•1h ago
Maybe AWS ParallelCluster which is a managed SLURM on AWS.

Capistrano? Fabric?

TS + Deno + dax is my favorite scripting environment. (Bun has a similar $ function built in.) For parsing CLI args, I like the builders from Cliffy (https://cliffy.io/) or Commander.js because you get typed options objects and beautiful help output for free.

If you want to script in Rust, xshell (https://docs.rs/xshell/latest/xshell/) is explicitly inspired by dax.

Oh! Well that makes sense.

Hey ibobev! I've actually been building something very close to box at a snail's pace for 2 years. I built it since I was working a lot with a bunch of raspberry pis where it was better to compile directly on the pi then on my mac but I didn't want to bother to ssh in or lose my local setup. The major difference with what I have so far is that the tool takes a direnv automagical approach to work with multiple machines across multiple projects/directories. It works across docker and ssh without any extra setup other than the tool on the client side.

I just got native LSP working this past weekend and in sublime it's as much as: { "clients": { "remote-gopls": { "command": [ "tool", "lsp", "gopls" ], "enabled": false, "selector": "source.go", }, } }

From what you built so far, do you think there's any appetite in people paying for this type of tool which lets you spin up infra on demand and gives you all the capabilities built so far? I'm skeptical and I may just release it all as OSS when it gets closer to being v1.0.

> do you think there's any appetite in people paying for this type of tool which lets you spin up infra on demand and gives you all the capabilities built so far?

(I'm not the author) The easiest way to charge for this kind of software is to make it SaaS, and I think that's pretty gross, especially for a CLI tool.

> I'm skeptical and I may just release it all as OSS

It doesn't have to be one or the other: you could sell the software under libre[1] terms, for example.

Any time doing hand-rolled on demand spinning up of ec2 instances, be sure they are properly spun down later.

It's very easy to get hit with a massive bill due to just leaving instances around.

hendiatris•13m ago
I run

sudo shutdown +15 (or other amount of minutes)

when I need a compute instance and don’t want to forget to turn it off. It’s a simple trick that will save you in some cases.

> I am at the tail end of AI adoption, so I don’t expect to say anything particularly useful or novel.

Are they really late? Has everyone started using agents and paying $200 subscriptions?

Am I the one wrong here or these expressions of "falling behind" are creating weird FOMO in the industry?

giancarlostoro•26m ago
Is it FOMO if for $100 a month you can build things that takes months, and then refine them and polish them, test them, and have them more stable than most non-AI code has been for the last decade plus? I blame Marketing Driven development for why software has gone downhill. Look at Windows as a great example. "We can fix that later" is a lie, but not with a coding agent. You can fix it now.
anonymous908213•14m ago
> Is it FOMO if for $100 a month you can build things that takes months

It is the very definition of FOMO if there is an entire cult of people telling you that for a year, and yet after a year of hearing about how "everything has changed", there is still not a single example of amazing vibe-coded software capable of replacing any of the real-world software people use on a daily basis. Meanwhile Microsoft is shipping more critical bugs and performance regressions in updates than ever while boasting about 40% of their code being LLM-generated or whatever. It is especially strange to cite "Windows as a great example" when 2025 was perhaps one of the worst years I can remember for Windows updates despite, or perhaps because of, LLM adoption.

CurleighBraces•20m ago
I've paid, but I am usually quick to adopt/trial things like this.

I think for me it's a case of fear of being left behind rather than missing out.

I've been a developer for over 20 years, and the last six months has blown me away with how different everything feels.

This isn't like JQuery hitting the scene, PHP going OO or one of the many "this is a game changer" experiences if I've had in my career before.

This is something else entirely.

rootnod3•7m ago
Just because it feels faster or are you actually satisfied with the code that is being churned out? And what about long term prospects of maintaining said code?

>Has everyone started using agents and paying $200 subscriptions?

If anything in my small circle the promise is waning a bit, in that even the best models on the planet are still kinda shitty for big project work. I work as a game dev and have found agents to only be mildly useful to do more of what I've already laid out, I only pay for the $100 annual plan with jetbrains and that's plenty. I haven't worked at a big business in a while, but my ex-coworkers are basically the same. a friend only uses chat now because the agents were "entirely useless" for what he was doing.

I'm sure someone is getting use out of them making the 10 billionth node.js express API, but not anyone I know.

For the past 20 years the population of the internet has been increasingly sorted into filter bubbles, designed by media corporations which are incentivized to use dark patterns and addictive design to hijack the human brain by weaponizing its own emotions against it to create an illusion of popular consensus. To suggest that someone who has been vibecoding for only a few months is at the tail end of mass adoption is to reveal that one's brain has been pickled by exposure to Twitter.
rootnod3•9m ago
Definitely FOMO. I have tried it once or twice and saw absolutely zero value in it. I will stick to writing the code by hand, even if it's "boring" parts. If I have to sit down and review it anyway, I can also go and write it myself.

Especially considering that these 200$ subscriptions are just the start because those companies are still mostly operating at a loss.

It's either going to be higher fees or Ads pushed into the responses. Last I need is my code sprinkled with Ads.

kibwen•7m ago
Good news, if you upgrade to our $300 plan you can avoid all ads, which will instead be injected into the code that you ship to your users.
css_apologist•26m ago
this isn't technically vibe coding right? this is just like using llms here and there for details you don't care to learn more about
indigodaddy•16m ago
My personal definition/interpretation would be if it's more than 50% of the project's code/work, even if one is reviewing the code (to whatever extent).
indigodaddy•20m ago
This is excellent and innovative, good stuff! I guess my only comment is why not just Ansible, but this feels like a way simpler and better fit (and more fun/cool! Plus you can just easily modify/bend the tool to your liking/need) just for playing around in your local homelab etc
nromiun•18m ago
> The spec ended up being 6KiB of English prose. The final implementation was 14KiB of TypeScript.

Wait, this is how people vibe code? I thought it was just giving instruction line by line and refining your program. People are really creating a dense, huge spec for their project first?

I have not seen any benefit of AI in programming yet, so maybe I should try it with specs and like a auto-complete as well.
