TL;DR summary of stories on the internet
The author delves into the mathematical concept of x & -x equaling the largest power of 2 that divides x. The explanation begins with how numbers are represented in binary, leading to discussions on one’s complement and two’s complement for negative numbers. The focus then shifts to the mathemagical property involving the largest power of […]

Back in high school, I dealt with suspect hard drives, but nowadays, the improved technology makes modern drives more reliable. Despite owning many “spinning rust” HDDs, my laptops all use solid state drives due to their performance. Forensic analysis differs from consumer data recovery, utilizing file carving techniques to recover files efficiently. For consumer data […]
The helicity of neutrinos has only been observed in two states: left-handed neutrinos and right-handed antineutrinos, with the possibility of additional states depending on whether neutrinos are their own antiparticles. The MAJORANA DEMONSTRATOR experiment, located almost a mile underground, aims to determine if neutrinos are their own antiparticles through the observation of neutrinoless double-beta decay. […]
The author notes the sudden rise of AI art surpassing human artistic abilities with models like Stable Diffusion. The application of denoising diffusion models demonstrates a unique approach to generating samples from an unknown distribution by blending noise over many steps. This method simplifies the complexity of previous models by focusing on a one-directional mapping. […]
Helen Keller reflects on her life before her teacher arrived, describing a world without consciousness or understanding of self. Through tactual memory, she recalls her early experiences of anger, satisfaction, and desire. As she learns to communicate, Keller gains awareness of herself and others, eventually developing a deeper understanding of the world and her place […]
Microsoft has partnered with Khan Academy to offer teachers free access to the AI teaching assistant, Khanmigo, through their Azure cloud platform. Khanmigo can help teachers save up to five hours per week by providing lesson hooks, student performance insights, recommended assignments, and knowledge support. Additionally, Khan Academy will assist in training Microsoft’s Phi-3 model […]
In my free time, I created Scinamalink, a tool that allows users to send Magic login links with a single API call. Magic login links authenticate users’ sessions without the need for a password reset. I avoided using RabbitMQ for simplicity, opting for a single-process worker system. The system ensures reliability by starting with a […]
Scientists have discovered that a single defect in a 2D material, hexagonal boron nitride (hBN), can retain quantum information for a surprising length of time at room temperature. This spin coherence property allows for the storage of quantum information for approximately 1 millionth of a second, without the need for special conditions or large magnets. […]
In this paper, researchers address the challenges surrounding the evaluation of language models in NLP. They highlight issues such as model sensitivity, comparison difficulties, and the lack of reproducibility. Drawing on three years of experience, they offer guidance and best practices for researchers in the field. The authors also introduce the Language Model Evaluation Harness […]
LogsQL is a powerful query language for VictoriaLogs, offering full-text search with word, phrase, and prefix filters. It allows complex logical filters, structured field extraction, and statistical calculations. Users can filter logs based on specific timeframes, words, and fields, with options to exclude certain logs using the NOT operator. The use of explicit parentheses can […]
