RAG-powered conversational research assistants address the limitations of traditional language models by combining them with information retrieval systems. The system searches through specific knowledge bases, retrieves relevant information, and presents it conversationally with proper citations. This approach reduces hallucinations, handles domain-specific knowledge, and grounds responses in retrieved text. In this tutorial, we will demonstrate building such an assistant using the open-source model TinyLlama-1.1B-Chat-v1.0 from Hugging Face, FAISS from Meta, and the LangChain framework to answer questions about scientific papers. First, let’s install the necessary libraries: !pip install langchain-community langchain pypdf sentence-transformers faiss-cpu transformers accelerate einops Now, let’s import the required…

Backdoor secrecy The hardcoded password flaw, identified as CVE-2024-20439, could be exploited to achieve administrator privileges via the app’s API. The second flaw, CVE-2024-20440, could allow an attacker to obtain log files containing sensitive data such as API credentials. With both given an identical CVSS score of 9.8, it’s a toss-up as to which is the worst of the two. However, the vulnerabilities could clearly be used together in ways that amplify their danger, making patching even more imperative. The affected versions of CSLU are 2.0.0, 2.1.0, and 2.2.0; version 2.3.0 is the patched version. CSLU is a recent product,…

A partial solar eclipse will come to Earth on Saturday, March 29, 2025, as the moon passes in front of the sun. From Earth, photographers will capture images of a bite being taken out of the sun. From space, a fleet of satellites will image a shadow being cast across Earth.The moon projects two kinds of shadows at all times. There’s a large fuzzy outer shadow, called the penumbra, and a much smaller, darker central shadow, the umbra. The latter causes a total solar eclipse, which is seen across a dark and narrow corridor on Earth called the path of…

More than 50,000 people have been killed in the Gaza Strip since the war began, the territory’s Hamas-run health ministry has announced.

Figures from the Gaza Ministry of Health (MoH) have been widely used in times of conflict and are seen as reliable by the United Nations (UN) and international institutions. But Israel has consistently refuted data published by Gaza’s…

We may receive a commission on purchases made from links. There are plenty of wild theories about “The Big Bang Theory” out there (which feels particularly bonkers when you consider that we’re talking about a laugh-tracked multi-camera sitcom created by Chuck Lorre), but this one about Bernadette Rostenkowski-Wolowitz, the waitress turned microbiologist with a crazy high voice who marries Howard Wolowitz (Simon Helberg) during the series, is especially out of left field. Over on the r/FanTheories subreddit, the appropriately named Redditor u/ConspirOC posited something pretty extreme about Bernadette. Titling the post “Bernadette…
