Oscar: A Practical Page-Permissions-Based Scheme for Thwarting Dangling Pointers (2017) (usenix.org)
Abstract: "Using memory after it has been freed opens programs up to both data and control-flow exploits. Recent work on temporal memory safety has focused on using explicit lock-and-key mechanisms (objects are assigned a new lock upon allocation, and pointers must have the correct key to be de...

Local web-based notes app inspired by "One Big Text File" with webpage downloads (github.com)
I really like the idea of "One Big Text File" ([old Lobste.rs discussion](https://lobste.rs/s/ettc1n/my_productivity_app_is_single_txt_file)) as a simple productivity tool. So I made a very simple UI on top of a single `notes.md` file with a few features: - Notes are rendered on a HTML page, serv...

RAG Without Vectors – PageIndex: Reasoning-Based Document Indexing
We were frustrated by vector-based RAG systems that rely on semantic similarity and often fail on long, domain-specific documents. In these contexts, domain-specific terminology tends to be semantically similar, making it hard to retrieve the exact content users need. It’s also difficult to incorpor...

Traditional vector-based RAG often struggles with retrieval accuracy because it optimizes for similarity, not relevance. But what we truly need in retrieval is relevance, which requires reasoning. When working with professional documents that require domain expertise and multi-step reasoning, vector...
