The cochlea processes sound by utilizing the vibrations received from the tympanic membrane (eardrum) and amplified by the middle ear bones. These vibrations travel through fluid in the cochlea and reach the basilar membrane, which separates frequencies: the stiff base resonates with high frequencies, while the flexible apex resonates with lower ones, creating a logarithmic frequency gradient. Hair cells on the basilar membrane respond to these vibrations and convert mechanical motion into electrical signals through a process involving ion channels. The auditory system

Apple's Vision team introduced their innovative telepresence feature, called Personas, within the Vision Pro VR headset. This feature allows multiple users, all wearing Vision Pros, to communicate in real time as virtual replicas of themselves through 3D photo scans. While various companies have explored telepresence using avatars, Apple's Personas stands out as the most advanced in the VR and AR space. During a recent meeting in the headset, the author experienced the immersive technology firsthand with Apple's Jeff Norris and Steve Sinclair, noting that

The author announces the release of llm-docs-builder, an open-source library designed to optimize Markdown documentation for Large Language Models (LLMs) by reducing unnecessary noise. The tool can strip away 85-95% of non-essential content, such as HTML formatting, allowing AI systems like Claude and ChatGPT to focus on the relevant documentation. This transformation significantly reduces costs associated with Retrieval-Augmented Generation (RAG) by minimizing the token usage in typical HTML documents. Metrics from the Karafka framework

Fil-C is a memory-safe implementation of C and C++ designed to allow existing C code to run safely without modifications. Its focus on compatibility makes it ideal for retrofitting memory safety into current applications. Despite being a relatively new project with a single active contributor, it can compile a complete memory-safe Linux user space and includes features like safe signal handling and a concurrent garbage collector. Fil-C is a fork of Clang, licensed under Apache v2.0 with LLVM exceptions, and it merges

Ubuntu has enhanced its compatibility in version 25.10 by introducing support for architecture variants, allowing packages to target specific levels of the x86-64 architecture (e.g., x86-64-v3). This initiative aims to optimize package performance on modern processors while maintaining support for older hardware. The development process involves modifying dpkg, apt, and Launchpad to facilitate the package building for various architecture levels. Initially, around 2000 packages in the main repository have been optimized for x86

Last week, during a public conversation, the author realized they failed to practice what they preach about open discussions when they privately messaged a colleague for clarity on who should handle a request. The author promotes documented decisions and public conversations to keep the team informed but recognized their own inconsistency. They reflected on recurring patterns of private communication across various companies, including: 1. **Pre-Flight Check**: Individuals seeking validation or approval in private before sharing publicly. 2. **The Great Migration**: Discussions

Recent findings by security firm Koi have highlighted a significant vulnerability in the NPM (Node Package Manager) ecosystem that allows attackers to exploit "Remote Dynamic Dependencies" (RDD). This weakness has enabled the "PhantomRaven" campaign to introduce over 126 credential-stealing packages into the NPM repository since August, with more than 86,000 downloads. These malicious packages can pull in untrusted dependencies from external websites, some of which are unencrypted, making them difficult for developers and static

In December 1995, IBM released OS/2 Warp, PowerPC edition (OS/2 PPC) after a lengthy development period. Despite the anticipation surrounding its launch, the release was low-key and marked the end of PowerPC development for OS/2. It was limited to select IBM customers and lacked strong marketing, potentially releasing without a box but with attractive CDs. OS/2 PPC supported only a narrow range of hardware, primarily IBM's Personal Power Series computers, including desktop models 830

Three years after @kingyoPiyo's Pico-10BASE-T project showcased 10 Mbit/s Ethernet on the Raspberry Pi Pico, developer Steve Markgraf has introduced Pico-100BASE-TX, achieving a 100 Mbit/s Fast Ethernet transmitter purely through software. This implementation leverages programmable I/O (PIO) and direct memory access (DMA) for tasks such as MLT-3 encoding and scrambling, achieving a symbol rate of 125 MHz. It streams approximately 11 Mbyte

The article discusses the misconception that not knowing something signifies weakness, particularly among engineers who feel pressured to always have answers. The author argues that being comfortable with not knowing is actually a sign of experience, maturity, and seniority. The piece emphasizes that acknowledging one’s ignorance can be a valuable learning opportunity rather than a reflection of incompetence. It offers practical guidance on how to express “I don’t know” in a way that maintains credibility, through two real-world scenarios: building credibility within a team and
