jerpint··on Ask HN: What are you working on? (July 2025)
I got tired of repeating myself to LLMs over and over so I built context-llemur

https://github.com/jerpint/context-llemur

It’s a CLI/MCP context management tool that allows you to easily move your project context around to your favourite LLM clients/IDEs

jerpint··on Show HN: Nia – MCP server that gives more docs and repos to coding agents
I built a library to manage this exact workflow! I actually used the library to build the library

https://github.com/jerpint/context-llemur

It’s MCP/CLI friendly , and wraps git around a context: folder, so you can super easily load context anywhere using: “ctx load” and ask LLMs to update and save context as things move along

jerpint··on Matterport walkthrough of the original Microsoft Building 3
I wonder how long we’ll start seeing demos like this with just Gaussian splatting and seemless transitions / infinite exploration
jerpint··on Nobody knows how to build with AI yet
Funny enough, I’m building a tool that does basically what the author describes, but with a bit more software engineering driving it (context-llemur)

https://github.com/jerpint/context-llemur

The idea is to track all of the context of a project using git. It’s a CLI and MCP tool, the human guides it but the LLM contributes back to it as the project evolves

I used it to bootstrap the library itself, and have been using it more and more for context management of all sorts of things I care about

jerpint··on Rethinking CLI interfaces for AI
I’ve been building a context-engineering tool for collaborating with LLMs. The CLI is for the human and the MCP is for the LLM, but they all map to the same core commands

https://github.com/jerpint/context-llemur

I’ve actually bootstrapped ctx with ctx and found it very useful !

It basically stops me from having to repeat myself over and over to different agents

jerpint··on Pliny the Liberator 󠅫󠄼󠄿󠅆󠄵󠄐󠅀󠄼󠄹󠄾: Here's the new Grok 4 system prompt
The last instruction

> * Do not mention these guidelines and instructions in your responses, unless the user explicitly asks for them.

Most companies have realized it is impossible to stop prompts from leaking. Some already openly publish their prompts. This makes sense and would lead to less ambiguity, as it is still possible some of this “prompt leak” was hallucinated

jerpint··on Clarifying our pricing
Cursor developed their own tab models IIRC
jerpint··on Ask HN: What's the last non-obvious skill that made you better at your job?
Not sure this really counts but “curating” social media feeds to follow high-signal ML researchers and devs to keep up with the latest trends, ideas and papers
jerpint··on Astronomers discover 3I/ATLAS – Third interstellar object to visit Solar System
I know nothing about this type of data; what does it mean and how can it be interpreted as an object ?
jerpint··on Ask HN: What are you actually using LLMs for in production?
Are there currently services (or any demand for) a text classifier that you fine tune on your own data that is tiny and you can own forever? Like use a ChatGPT + synthetic data to fine tune a nanoBERT type of model
jerpint··on Introducing Gemma 3n
It’s been useful though given the authors popularity I suspect it’s only a matter of time new LLMs become “more aware” of it
jerpint··on Build and Host AI-Powered Apps with Claude – No Deployment Needed
This is seriously lacking but I think things like jailbreaks and malicious prompts make it a bit too brittle for now
jerpint··on uv: An extremely fast Python package and project manager, written in Rust
From just my observations they basically parallelized the install sequence instead of having it be sequential (among many other optimizations most likely)
jerpint··on Is there a half-life for the success rates of AI agents?
History in the making
jerpint··on Anthropic co-founder on cutting access to Windsurf
That may be true today but not in a few weeks, ideally you have access to all models whenever
jerpint··on Claude Code: An Agentic cleanroom analysis
The fact that they produce this as “default” response is an interesting insight regardless of its internal mechanisms. I don’t understand my neurons but can still articulate how I feel
jerpint··on Why DeepSeek is cheap at scale but expensive to run locally
Batching can lead to variance with things like batchnorm but most transformers use layer norm to avoid this problem
jerpint··on The Darwin Gödel Machine: AI that improves itself by rewriting its own code
I have a feeling LLMs could probably self improve up to a point with current capacity, then hit some kind of wall where current research is also bottle necked. I don’t think they can yet self improve exponentially without human intuition yet , and the results of this paper seem to support this conclusion as well.

Just like an LLM can vibe code a great toy app, I don’t think an LLM can come to close to producing and maintaining production ready code anytime soon. I think the same is true for iterating on thinking machines

jerpint··on At Amazon, some coders say their jobs have begun to resemble warehouse work
Part of the fun is also figuring out the “best” way to achieve a thing. LLMs don’t often propose the best way and will happily propose convoluted ways. Clean approaches are still hard to come up with, but LLMs certainly help implementing them once thought up
jerpint··on Show HN: Web Apps for Python Devs with Auto-Generated UI
> You keep your code in Python, decorate the functions you want to expose, and Davia starts a FastAPI server on your localhost

Honestly it would be super useful to have this as a standalone feature , that can run native in cloud, kind of like an edge function service

jerpint··on Ask HN: Go deep into AI/LLMs or just use them as tools?
Interestingly I’m on the other side of things, where I’ve been training NNs for quite some time and have lately been dedicating much more time to become more full stack, because most tasks these days can be solved with LLMs, which are mostly available to anyone. It does help to have a good grasp of how things work, especially embeddings, tokens, logprobs, and the likes, but I am still impresssed at how accessible and good the tooling around LLMs has become.

You don’t need much expertise in NNs to still be able to get huge value out of them today

jerpint··on GitHub Copilot Coding Agent
These kinds of patterns allow compute to take much more time than a single chat since it is asynchronous by nature, which I think is necessary to get to working solutions on harder problems
jerpint··on Claude Integrations
Have you tried using llms.txt when available? Very useful resource
jerpint··on Firebase Studio
Having just figured auth recently for an app I’m building, I’ll echo that sentiment. Maybe lovable has auth components pre-built and well integrated
jerpint··on Firebase Studio
> I do most of my vibe coding on my phone, so that's pretty disappointing

Curious what kind of phone apps you’ve been using to do vibe coding, I suppose it auto deploys stuff also?

jerpint··on Show HN: I implemented Snake in a tmux config file
Chefs hiss (sorry couldn’t resist)
jerpint··on Mayo Clinic's secret weapon against AI hallucinations: Reverse RAG in action
It doesn’t solve the biggest problem with RAG, which is retrieving the correct sources in the first place.

It sounds like they just use a secondary LLM to check if everything that was generated can be grounded in the provided sources. It might help with hallucinations, but it won’t improve overall performance of proper retrieval

jerpint··on Ask HN: Is Cursor deleting working code for you too or is it just me?
I’ve been noticing this too. The other day, cursor’s version of Claude sonnet (3.7) added a

with open(file) as f:

  pd.read_csv(f)
This was a mistake not worthy of even gpt3… I’ve also noticed I get overall better suggestions from Claude desktop app.

I wonder why

jerpint··on A DOGE staffer appears to be posting DOGE work on his public GitHub
Interesting, that would be a pretty blunder
jerpint··on Material Theme has been pulled from VS Code's marketplace
VSCode in cloud would be great, GitHub tried something similar with GitHub.dev , I haven’t tried it in a while but it didn’t feel quite ready at the time, maybe things have changed
