Demystifying Advanced RAG Pipelines: This web content aims to shed light on how advanced RAG pipelines, powered by large language models, work. While frameworks like LlamaIndex and Haystack provide abstraction for building these pipelines, they lack transparency. The content explains the inner workings of RAG pipelines, including the processes of retrieval-augmented generation, sub-question generation, vector/summary […]

Google has conducted research into audioplethysmography (APG), a technology that adds heart rate sensing capabilities to active noise canceling (ANC) headphones and earbuds through a software upgrade. This approach involves sending a low intensity ultrasound probing signal through the headphones, which triggers echoes that are received by feedback microphones. These echoes are then processed into […]
A team of scientists from Cambridge University claim to have successfully simulated a method of backward time travel using quantum entanglement. Although they emphasize that they haven’t built a time machine, the researchers explain how their process doesn’t violate the laws of physics. By manipulating the entangled particles in their simulations, they were able to […]
The SSL/TLS protocols have revolutionized secure communication over computer networks, but their beginnings were far from perfect. The first version, SSLv2, released in 1995, quickly revealed numerous security flaws. This led to the development of the more secure SSLv3, which had its own issues. Despite SSLv2 being deprecated since 2011, there are still web servers […]
In this web content, the author expresses concern about a new protocol called Guppy, which is based on UDP (User Datagram Protocol) instead of TCP (Transmission Control Protocol). While UDP is simpler and allows for faster transfer speeds, it is vulnerable to amplification attacks. The author shares a personal experience with shutting down a UDP […]
ScratchDB is a wrapper around Clickhouse that allows users to input arbitrary JSON and perform analytical queries on it. What sets ScratchDB apart is that it automatically creates tables and columns when new data is added. To get started, users need to clone the repo and start the Clickhouse and localstack servers. Then, they can […]
The latest research from DeepMind challenges the common belief that transformers, specifically Vision Transformers (ViT), outperform convolutional networks (ConvNets) on extremely large datasets. Previous studies comparing ViT with ConvNets used weak baselines and large computational budgets, making the results questionable. In this study, the authors use Normalizer-Free ResNets (NFNet), a purely convolutional architecture, to achieve […]
Oil and gas company BP has agreed to buy $100 million worth of electric vehicle chargers from Tesla. This is a first for Tesla, as they have never sold chargers to another company before. BP will start installing the chargers next year, although the announcement does not specify how many chargers will be purchased. These […]
Thirty years ago, engineer Christopher Walker had a serendipitous moment while making chocolate pudding. His mother’s call distracted him, causing him to cover the pot with plastic wrap. When he returned, he noticed the warped plastic reflected light and had an innovative idea. This idea eventually became the Large Balloon Reflector (LBR), an inflatable device […]
is a novel browser engine created entirely in JavaScript. The project was started for fun and as a learning experience. It functions by taking a URL and rendering it into a window for viewing and interaction. Although it may not work with most websites, the developer finds it amusing to see people’s reactions. The name […]
