cobolexpert··on Emacs Turns 50
> Is anybody here consciously trying to keep their Emacs configs/setup "lean", minimalist, as small as possible?

Me too, for some reason. I've been using Emacs for 8 years and my init.el is 94 lines long. I guess the defaults mostly work for me.

cobolexpert··on Ask HN: What are you reading?
Also reading IJ! Got to 50% this week, but it took me about 10 months. I’m a slow reader I think. However, I’m taking notes as I read to help me track how the different characters are connected.

Any connection to https://github.com/CeleritasCelery/rune ?

Thanks for the heads-up

Makes sense! Thanks for sharing.

How does the classifier work? I see some JSON files with commands in them.

I like this tree visualization! The background with little squares is making the text difficult to read, though.
cobolexpert··on Is Show HN dead? No, but it's drowning
Had a funny experience with this some weeks ago. I started developing a small side project and after a week I wondered if this existed already. To my surprise, someone had already built something relatively similar _with the exact same name_ (though I had chosen mine as a placeholder, still funny though) only 2 weeks before, and posted it in Show HN.

I took a look at the project and it was a 100k+ LoC vibe-coded repository. The project itself looked good, but it seemed quite excessive in terms of what it was solving. It made me think, I wonder if this exists because it is explicitly needed, or simply because it is so easy for it to exist?

cobolexpert··on I want to wash my car. The car wash is 50 meters away. Should I walk or drive?
Changed 50 meters to 43 meters with Opus 4.6:

“Walk. 43 meters is basically crossing a parking lot. ”

Same here, I find most of these skills/prompts a bit redundant. Some people argue that in including these in the conversation, one is doing latent space management of sorts and bringing the model closer to where one wants it to be.

I wonder what will happen with new LLMs that contain all of these in their training data.

cobolexpert··on Ex-GitHub CEO launches a new developer platform for AI agents
Yep exactly, a Perl script
cobolexpert··on Bazzite Post-Mortem
As it slowly starts working on another platforms, it can fill in Bazzite's role (a bit ironic I guess, given Bazzite is inspired on SteamOS)
cobolexpert··on Bazzite Post-Mortem
Maybe SteamOS will help with this!

Relevant comment from some months ago [1].

Personally I find that sticking to distros backed by companies or very large communities is just easier in the long term (Debian/Ubuntu/Fedora/Arch).

Dumb question: is the quadratic time complexity for training, inference, or both?
cobolexpert··on The Codex App
In the end this and all other 89372304 AI projects are just OpenAPI/Anthropic API wrappers, but at least one has 1st party support which maybe gives it a slight advantage?

Copilot wanting to name everything Copilot is a funny thought, for some reason.
cobolexpert··on ChatGPT Containers can now run bash, pip/npm install packages and download files
Indeed, but nowadays it’s common to add the annotations to claw back a bit of more powerful code linting.

I was also thinking this some days ago. The scaffolding that static languages provide is a good fit for LLMs in general.

Interestingly, since we are talking about Go specifically, I never found that I was spending too much typing... types. Obviously more than with a Python script, but never at a level where I would consider it a problem. And now with newer Python projects using type annotations, the difference got smaller.

cobolexpert··on The browser is the sandbox
In which way does native UI have the upper hand, do you think? To me it seems like a lot of users are largely indifferent to this aspect (e.g. so many applications nowadays being Electron/browser based). If browsers keep gaining capabilities then it seems like this gap will get even smaller.
cobolexpert··on Why Does Destroying Resources via TF Suck?
At $WORK we have a Git repo set up by the devops team, where we can manage our junk by creating Terraform resources in our main AWS account.

The state however is always stored in a _separate AWS account_ that only the devops team can manage. I find this to be a reasonable way of working with TF. I agree that it is confusing though, because one is using $PROVIDER to both create things and manage those things at the same time, but conceptually from TF’s perspective they are very different things.

cobolexpert··on The Agentic AI Handbook: Production-Ready Patterns
Maybe my initial message was overly harsh, I mostly agree with your points here. I think maybe the point of disagreement is exactly _how much_ extra prompt is necessary to approach 100% of the job, but this is quite hard to measure (obviously). Your point about latent space management is a good mental model to have IMO.

Ah do you mean sub-agents? I do understand that if I summon a sub-agent and give it e.g. code reviewing instructions, it will not fill up the context of the main conversation. But my point is that giving the sub-agent the instruction "review this code as if you were a staff engineer" (literally those words) should cover most use cases (but I can't prove this, unfortunately).

I agree about the small tweaks like the Ruby accessor thing, I also have some small notes like that myself, to nudge the agent in the right direction.
cobolexpert··on The Agentic AI Handbook: Production-Ready Patterns
This is something that continues to surprise me. LLMs are extremely flexible and already come prepackaged with a lot of "knowledge", you don't need to dump hundreds of lines of text to explain to it what good software development practices are. I suspect these frameworks/patterns just fill up the context with unecessary junk.
