   LocalGPT – A local-first AI assistant in Rust with persistent memory▲331

   I built LocalGPT over 4 nights as a Rust reimagining of the OpenClaw assistant pattern (markdown-based persistent memory, autonomous heartbeat tasks, skills system). It compiles to a single ~27MB binary — no Node.js, Docker, or Python required. Key features: - Persistent memory via markdown files (MEMORY, HEARTBEAT, SOUL markdown files) — compatible with OpenClaw's format - Full-text search (SQLite FTS5) + semantic search (local embeddings, no API key needed) - Autonomous heartbeat runner that checks tasks on a configurable interval - CLI + web interface + desktop GUI - Multi-provider:…

   Manta – A tool for FPGA Debugging and Rapid Prototyping▲86

   Hi HN! I'm Fischer, and I'm super stoked to share a project that I've been working on for a little over a year: Manta, an open-source, cross-platform, vendor-independent tool for debugging and rapid prototyping with FPGAs. This was originally my Master's Thesis at MIT, where I developed it for our course on FPGA design. We needed an alternative to vendor debugging tools, which only supported x86 machines running Windows or Linux. We were able to patch in macOS support with VMs, but as more students came bringing ARM-based devices, we needed a new tool. So I developed this. It's called Manta,…

    Rotta-Rs, Deep Learning Framework in Rust Release 0.0.3▲7

    ROTTA-rs is a deep learning library in Rust focused on simplifying AI model creation. ROTTA-rs has now released version 0.0.5, adding many features, including: - RMSProp - Adam - Batch Norm - Layer Norm - and new additional features for creating tensors, mean, and simplifying tensor slicing. Version 0.0.5 also adds Dataset and DataHandler to simplify data manipulation, such as shuffling and splitting input into batches.

    I made a set of tools to write kernel prototypes.▲8

    This is a personal project I've been working on and off for the past few years. It's a set of tools that have allowed me to prototype quickly small (and increasingly bigger) kernels, and create userspace programs to interact with them. Supports riscv64, amd64 and i386. The intel port has been tested and used on real hardware, from big dual-socket Xeon machines to an old X220. It is all C, I have plan to make rust bindings for the kernel library. But again, they're plans at this stage. Porting to new architectures is relatively simple, a basic port to riscv took me a couple of weeks of…

    KVBoost – chunk-level KV cache reuse for HuggingFace, 5–48x faster TTFT▲20

    If you’ve ever been curious about how GPT actually works under the hood, I built a small project you might find interesting. I implemented a GPT-style transformer from scratch in a single notebook—covering tokenization, embeddings, causal self-attention, training, and autoregressive text generation without relying on high-level abstractions. The focus was on mechanistic clarity rather than scale or performance, and the notebook is structured to read more like a technical walkthrough than an experiment log. Feedback from people who’ve built or studied transformers would be very welcome.
