Hi. I made Easylang to help beginners get started with programming. It is open source. https://github.com/chkas/easylang Why I think Easylang is for beginners better than Python. https://easylang.online/blog/easyl_pyth.html UPDATE: The posted link goes directly to the beginner tutorial. This is the start page of the IDE. https://easylang.online/ide/

I've built many interpreters over the years, and Bolt represents my attempt at building the scripting language I always wanted. This is the first public release, 0.1.0! I've felt like most embedded languages have been moving towards safety and typing over years, with things like Python type hints, the explosive popularity of typescript, and even typing in Luau, which powers one of the largest scripted evironments in the world. Bolt attempts to harness this directly in the lagnauge rather than as a preprocessing step, and reap benefits in terms of both safety and performance. I intend to be…

I made this simple language over the past year, and it's time for me to say it's "done" (for now) and focus on other projects. I've struggled to answer the question "what is this language for?" other than "it's just for me" — and that's probably good enough. But I also wanted to make something "complete" that others could use if they wanted to. Writing my own language was an incredibly rewarding experience, and I'd recommend everyone trying it. Let me know if you have any questions or feedback, and please share your own experience if you've also made a language.
- SAScrapScript – A tiny functional language for sharable software2023 · scrapscript.org · ▲503
Hi friends, I started casually working on scrapscript in 2015. I built a few compilers over the years to test out various ideas/implementations, and I think I'm finally happy with the overall design. The code is not public yet. Email me at [email protected] if you're interested in joining the core team later this year. Let me know if you have any questions or feedback :)

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
