jasfi··on Clef: Open-source decision models, and new RL fine-tuning platform
Related: an intelligence cache for decision model data: https://cachev.dev

I built this for my own needs, and thought others might find it useful too.

jasfi··on Show HN: An intelligent cache for decision model data
I was building a trading indicator with Jev and wanted an intelligent cache to reduce the volume of usage-based API calls. That's when I came up with the idea for CacheV, it's built specifically for that use case, and works with any decision model.

A software factory: https://sfactory.dev
jasfi··on Debian: Retiring from the Project (Vv221)
LLMs wouldn't work without learning on massive amounts of text, so using the entirety of human thought and existence is a very practical step. I wouldn't worry about the reselling part, because AI is a race towards the best price/performance. Open weights models are driving the price down a huge amount, making this tech more practical for everyone.
jasfi··on AI Writing Without the Slop
I'm looking for beta testers for Sfactory. Right now it's focused on quality AI writing. Please give it a try if this is of interest to you.
jasfi··on Show HN: Huzzah – a novel approach to coding with AI
I wrote something similar, but as others have pointed out not having a formal language can be a hindrance.

I played it! Couldn't remember the name but it is the same game as linked to that I do remember.
jasfi··on Low Vitamin B9 and B12 linked to chronic fatigue and low motivation
I've read that you should take K2 if you take D3. You might want to research that. Also 500 IU of D3 is really low.
jasfi··on A recent experience with ChatGPT 5.5 Pro
It's about the ability to combine ideas in novel ways, without breaking the rules in relevant frameworks. Sometimes the idea may even be to contradict existing theories where they are weak.
jasfi··on Show HN: I made a "programming language" looking for feedback
I wrote IntentCode, but it seems to have gone under the radar: https://github.com/jfilby/intentcode
jasfi··on Kotlin creator's new language: talk to LLMs in specs, not English
I've built an AI compiler that has my take on this: https://github.com/jfilby/intentcode
jasfi··on We should revisit literate programming in the agent era
I wrote something similar where you specify the intent in Markdown at the file level. That can also be done by an AI agent. Each intent file compiles to a source file.

It works, but needs improvement. Any feedback is welcome!

jasfi··on Show HN: IntentCode
Hi HN,

I wrote IntentCode to let people write high-level specs in natural language, or directly in pseudo-code (Markdown with guidelines I call the IntentCode).

This is an AI compiler, the IntentCode files get compiled to source 1:1. The examples so far are quite basic (calc CLI app) but prove that the concept is sound.

You can also write extensions, which are mainly skills files for now.

I intend to keep progressing the compiler, so that larger and more complex examples can be implemented.

jasfi··on Humanity's Last Programming Language
I wrote something similar: https://intentcode.dev
jasfi··on Ask HN: What are you working on? (February 2026)
An AI compiler, releasing later today: https://intentcode.dev
jasfi··on LLMs could be, but shouldn't be compilers
I'm actually building this and believe I've overcome the most difficult aspects mentioned here. It will be released as Open Source next week. https://intentcode.dev
jasfi··on Rust’s Standard Library on the GPU
Benchmarks would be nice to help understand the performance implications.
jasfi··on OpenAI to Take a Percentage from Customer AI-Assisted R&D Outcomes
Likely if they sponsor a ton of tokens.
jasfi··on Nanolang: A tiny experimental language designed to be targeted by coding LLMs
I'm actually building this, will release it early next month. I've added a URL to watch to my profile (should be up later this week). It will be Open Source.
jasfi··on Ask HN: What did you find out or explore today?
Try Lutein (20mg).
jasfi··on CEOs are hugely expensive. Why not automate them? (2021)
That's a role that would require AGI, we're not there yet.
jasfi··on Hacker News front page now, but the titles are honest
Please add a 2nd page.
jasfi··on Thoughts on Go vs. Rust vs. Zig
Nim hit the spot for a good low-level, fast language for me. The recommended GCs work well and it's easy to use.
jasfi··on People with blindness can read again after retinal implant and special glasses
Sorry to hear that. Given that it's genetic only something like Crispr could perhaps one day help.
jasfi··on People with blindness can read again after retinal implant and special glasses
Lutein may prevent or slow it. It's the best general eye supplement I've found too.
jasfi··on I forced myself to spend a week in Instagram instead of Xcode
Thanks, it looks professionally done.

What are you using to put your videos together?
jasfi··on OpenAI’s latest research paper demonstrates that falsehoods are inevitable
Easily solved, pairs of models, one which would rather say IDK, one which would rather guess. Most AI agents would want the IDK version.
jasfi··on HN Search isn't ingesting new data since Friday
I noticed this too, using it for https://kindred.fit.
jasfi··on Do Things That Don't Scale (2013)
That's why "make something people want" is such a core saying for startups.
