In this research, Retrieval-Augmented Large Language Models (LLMs) are explored as a way to improve response accuracy in tasks like Question-Answering (QA). Current approaches either add unnecessary computational complexity to simple queries or struggle with multi-step queries. To address this, a new adaptive QA framework is proposed, using a classifier to select the best strategy […]

“Cpp2” is Herb Sutter’s personal project aiming to simplify and make writing ordinary C++ functions and types safer without disrupting backward compatibility. It is not an alternate language but rather a new “skin” for C++, using existing modules and concepts seamlessly. The goal is to provide a simpler and safer way to write C++ code […]
Ray Tomlinson, an MIT graduate, sent the first email over a network in October 1971. Fast forward 50 years, and around 121 trillion emails are sent yearly among 4.3 billion individuals, making email the paramount form of written communication worldwide. Google, Yahoo, and Outlook.com (formerly Hotmail) recently announced stricter email security protocols to counter spam […]
The authors introduce Jamba, a large language model combining Transformer and Mamba layers using a mixture-of-experts architecture. This flexible design allows for efficient parameter usage and high performance, fitting in a single 80GB GPU. Jamba excels in long-context evaluations, showing strong results for up to 256K tokens context length. The study explores key architectural decisions […]
On Mar 31st, 2024, a talented developer unveiled 84 innovative matrix multiplication kernels for llamafile on their webpage. These kernels help enhance image reading and prompt evaluation speed by 30% to 500% when using F16 and Q8_0 weights on CPU. The improvements are particularly impressive on ARMv8.2+, Intel, and AVX512 computers. Llamafile, the brainchild of […]
In this post, the author discusses the focus stage component of the IRIS technique for non-destructive inspection of chips. The focus stage, essential for controlling the sample’s fine positioning, features piezoelectric actuators for precise adjustments. The author describes their process of designing and building the focus stage using affordable parts, specifically piezo actuators intended for […]
Arvind Kejriwal, Delhi Chief Minister, is in custody of the Enforcement Directorate, and they are seeking access to his iPhone to obtain information about AAP’s election strategy. The ED has not found electronic evidence on his personal computers but has confiscated four mobile phones, including Kejriwal’s. He has refused to share his iPhone password. Kejriwal […]
Yesterday, Andres Freund alerted the community about a backdoor found in xz/liblzma affecting OpenSSH server, highlighting the effort put into discovering and investigating this issue. The obfuscated binary with the backdoor is intriguing, but the focus here is on the clever obfuscation methods in the initial bash stages. Two versions of xz/liblzma (5.6.0 and 5.6.1) […]
The author reflects on what makes a happy PhD student, jokingly suggesting that being married is the key. Richard Hamming’s impactful talk inspired the author to pursue a PhD in hopes of tackling significant issues. When faced with uncertainty and contemplating quitting, the author’s parents advised focusing on achievable goals, even if they result in […]
