hipp v0.5819, an experimental command line file compressor by Bogatov Roman, uses context mixing with sparse contexts for binary data. Unfortunately, enwik9 cannot be compressed due to high memory requirements. ppmz2 v0.81, another compression tool by Charles Bloom, focuses on PPM and has various options. XMill 0.8, an AT&T project, preprocesses XML files for compression. […]

To use openpilot in a car, you need a supported comma 3/3X device, software available at openpilot.comma.ai, a compatible car, and a car harness for installation. It’s possible to run openpilot on other hardware, although it requires more effort. The openpilot community welcomes contributions and offers bounties for external developers. The software follows strict safety […]
The author documents their journey in building a CNC microscope using off-the-shelf parts to image large objects like leaves and CD-ROMs with microscopic detail. Initially using plasticine to secure the microscope, they switch to neoprene tape for better stability. They highlight experimenting with magnifications, image sharpness, creating a Python script for image capture, measuring mean […]
A team of researchers has developed a novel approach called SCoRe to improve the self-correction capability of large language models (LLMs) without the need for multiple models or external supervision. Existing methods for training self-correction have been ineffective in modern LLMs. SCoRe utilizes online reinforcement learning to train the model using self-generated data, addressing challenges […]
Relational algebra may feel like more of an invention than a discovery, but it proves to be a valuable tool in the world of databases, tables, and spreadsheets. The author explores building “better spreadsheets” by using derived tables that function like database views, incorporating time-indexed paradigms inspired by functional reactive programming. They find that notation […]
MemoRAG is a groundbreaking RAG framework that enhances evidence retrieval by leveraging a memory model to achieve a global understanding of massive databases. It efficiently handles up to 1 million tokens in a single context with features like contextual clues and efficient caching. The project aims to achieve light-weight optimization and enhance memory capabilities for […]
Author booted Debian Linux on a real 4-bit intel 4004 microprocessor from 1971. The first microprocessor globally, it’s slow but fully running Linux. Describes the intricacies of the 4004’s one-operand instruction set, bizarre control flow mechanisms, and unique features like the absence of logical operators and memory access limitations. Detailed hardware construction, debugging, memory translation, […]
CuPy is a GPU-accelerated array library compatible with NumPy and SciPy, allowing existing Python code to run on NVIDIA CUDA or AMD ROCm platforms seamlessly. This tool offers low-level CUDA features like RawKernels and Streams for performance optimization, pushing the boundaries of what can be achieved with GPU computing. Installation is made easy with binary […]
Forbes has surprisingly dominated Google search results for various topics like pet insurance, CBD gummies, and cockroach infestations. They may be making over $100K/month just off a few blog posts. Despite claiming to be the best authority in these areas, Forbes isn’t actually an expert in these fields. Forbes Marketplace, a separate entity from Forbes, […]
Rendering APIs serialize gpu workloads into command-buffers, making it hard to track high-level operations. Tools like RenderDoc and Nsight help decode these buffers, but identifying specific commands remains a challenge. By adding object names and debugging scopes, post-decoding provides readable data for easier analysis. Implementing RAII patterns in C++, C#, and Rust automates scope management […]
