Your AI Forgets Everything. Here's How Cognee Fixes It.

Have you ever noticed this? You explain your project to an AI chatbot, have a great conversation, then come back later... and it asks you to explain everything again. Start a new chat, and it's like meeting you for the first time. This isn't a bug. It's how most AI models work—they don't remember past conversations on their own. That's where Cognee comes in. Instead of making AI start from scratch every time, it gives AI a way to remember what matters. Why does AI forget everything? Most AI models don't have long-term memory. Every time you start a new chat, the AI only knows what you send in that conversation. It doesn't remember your previous chats, your project, or your preferences unless you provide them again. A common solution is RAG (Retrieval-Augmented Generation) . It stores your documents in a searchable database so the AI can look up relevant information when needed. RAG genuinely helps, but it only knows what sounds similar. It doesn't know "Priya" and "the payments lead" are the same person, or that this week's ticket shares a root cause with one from March. Similarity search finds neighbors — it doesn't understand relationships. That's where Cognee takes a different approach. What is Cognee? Cognee is an open-source memory layer for AI applications. Instead of making an AI start from scratch every time, Cognee helps it remember information across conversations. It can learn from your documents, files, websites, or notes and use that knowledge whenever it's needed. Unlike traditional RAG systems that mainly find similar text, Cognee also understands how different pieces of information are connected. That gives AI more accurate and meaningful answers. It's Apache-2.0, runs locally by default, and has 27k+ GitHub stars. How does it work? At a high level, the process is simple: flowchart LR A[Text, Files, URLs] --> B[remember()] B --> C[Cognee builds AI memory] C --> D[recall()] D --> E[AI answers using remembered knowledge] For example: "Alice bought a Pr

LOOM: a language that proves what AI-written code is allowed to do

▶ Try it live (in your browser): https://umbraaeternaa.github.io/loom/play.html Built solo, in the open, from Ukraine 🇺🇦. The problem nobody can scale their way out of AI now writes a large and growing share of the code that runs in the world. The uncomfortable part isn't that the code is often wrong — it's that the same model frequently writes both the code and the tests that check it. When one intelligence authors the solution and the criteria, "it passed" quietly stops meaning "it's safe." The gate becomes foolable. You can make the model bigger, but a bigger model that grades its own homework is still grading its own homework. The honest answer isn't "trust a smarter model." It's: trust only what can be independently proven — and make that proof mechanical, not a matter of hope. That is the whole idea behind LOOM. What LOOM is LOOM is a small, open-source, effect-typed language that acts as a machine-checked trust layer for AI-written code. It doesn't just run code — it proves, at a gate, exactly what the code is allowed to do, before a single line executes. If the code lies about what it does, the compiler refuses it. The slogan is: AI proposes, the compiler disposes. Today it is a research kernel with 385 self-verifying checks, all green — every feature added only with an adversarial test, so the language can only ever get greener. There's a live browser playground where a stranger can paste a program and watch the checker accept or reject it in under a minute. What it can actually do Effect honesty. Every function declares its effects — Pure, IO, Net, Alloc, FFI, Rand. Declared effects must cover what the code actually does; the lie is caught transitively through calls, branches, recursion — not just straight-line code. Capabilities, not ambient power. A foreign call has no ambient authority — un-wrapped, it's refused. A seam is the only thing that grants authority, so (seam (Pure) (ffi untrusted)) makes that code's I/O physically impossible.

purefetch: a fastfetch-style system info tool in Rust with zero dependencies

I like neofetch / fastfetch , but I wanted one with a genuinely empty dependency graph — nothing pulled from crates.io. So I built purefetch : a small system-info fetcher written entirely in Rust using only std plus raw Linux syscalls. Disclosure up front: purefetch was built largely with AI assistance (Claude Code). I directed the design, and every change was reviewed and tested — including running it on four architectures under QEMU — but most of the code is AI-generated. I'd rather be honest about that than pretend otherwise. _,met$$$$$gg. ooonea@unicorn ,g$$$$$$$$$$$$$$$P. ────────────── ,g$$P" """Y$$.". OS Debian GNU/Linux 13.5 (trixie) x86_64 ,$$P' `$$$.

Almost everything is just reading and parsing /proc and /sys . The result is a single ~484 KiB binary that builds offline. The only things std can't do are statfs (disk usage) and ioctl (terminal size / tty check). Instead of pulling in a binding crate, those are issued as raw Linux syscalls via core::arch::asm! : #[cfg(target_arch = "x86_64" )] unsafe fn syscall3 ( n : usize , a1 : usize , a2 : usize , a3 : usize ) -> isize { let ret : isize ; core :: arch :: asm!
