OpenAI Outage: Unexpected Load from New Telemetry Service Causes Major Disruption

2024-12-16

OpenAI experienced a major service disruption on December 11th, stemming from a newly deployed telemetry service. Intended to improve reliability, this service unexpectedly generated massive Kubernetes API server load, saturating the servers and causing the Kubernetes control plane to fail in most large clusters. This led to the breakdown of DNS-based service discovery. The incident highlights the unpredictable interactions within complex systems and the challenges of testing for failure modes that only appear under full load. OpenAI restored service by scaling down clusters, blocking network access to Kubernetes admin APIs, and scaling up API servers.

Automated Assembly System Creates Cyborg Insects

2024-12-15

Scientists have developed an automated system for assembling insect-computer hybrid robots. The system uses a vision-guided robotic arm to precisely implant custom-designed bipolar electrodes onto the backs of Madagascar hissing cockroaches. The entire process takes only 68 seconds, and the assembled robots achieve steering and deceleration control comparable to manually assembled systems. A multi-agent system of 4 robots successfully navigated an obstacle course, demonstrating the feasibility of mass production and real-world applications. This research paves the way for scalable production and deployment of insect robots.

Displaying Website Content on an E-Ink Display: A Family Tech Solution

2024-12-15

To address the inconvenience of checking the school timetable, the author designed a low-power e-ink display that automatically fetches and displays the school website's timetable. The project overcame challenges of website login and API absence by using Playwright for web scraping, and a server-side application to generate the image, which is then displayed on the e-ink screen. This solution tackles a family's daily problem and showcases the combined application of low-power hardware and web scraping technologies. The project initially explored MicroPython, but ultimately utilized the Arduino library for better reliability and functionality.

RAM Data Remanence Times: Significant Differences Between DDR4 and DDR5

2024-12-15

3mdeb conducted research testing data remanence times in different RAM types (DDR4 and DDR5). Results showed DDR5 data vanishes almost instantly after power loss, while DDR4 data persists for significantly longer, up to two minutes. This highlights critical differences in data security between RAM types. A custom UEFI application was used, writing and comparing memory patterns while accounting for temperature and humidity. This research is significant for understanding memory data security and designing more secure systems.

Eventual Consistency: Challenges and Patterns in Distributed Systems

2024-12-13

Eventual consistency is unavoidable in distributed systems. This article explores four common patterns for handling eventual consistency: event-based eventual consistency, background sync eventual consistency, saga-based eventual consistency, and CQRS-based eventual consistency. Each pattern has its advantages and disadvantages. For example, the event-based pattern emphasizes loose coupling and scalability, but consistency takes time; while the saga-based pattern is suitable for complex, long-running transactions, ensuring consistency through compensating transactions. The choice of pattern depends on the specific needs and trade-offs of the system.

Generative AI and Fair Use: A ChatGPT Case Study

2024-12-14

This article examines whether generative AI models, particularly ChatGPT, qualify for fair use of copyrighted material. The author analyzes the four factors outlined in Section 107 of the US Copyright Act: purpose and character of use, nature of the copyrighted work, amount and substantiality of the portion used, and effect on the market. Through a case study of ChatGPT, the author argues that ChatGPT's use of its training data likely constitutes copyright infringement. ChatGPT's commercial nature and its failure to transform the training data, coupled with market harm to original works, contradict the principles of fair use.

Recursion Pharmaceuticals Ditches Cell Painting for Brightfield Imaging

2024-12-15

Recursion Pharmaceuticals, a biotech leveraging machine learning for drug discovery, recently announced a surprising shift: abandoning its signature cell painting technique in favor of traditional brightfield imaging. This article delves into the reasons behind this change. Advances in deep learning allow models to effectively process raw images, diminishing the value of cell painting's fluorescent dyes for contrast enhancement. Brightfield imaging offers advantages in cost, ease of implementation, and compatibility with live-cell time-lapse microscopy, opening up possibilities for studying cellular dynamics. Despite the seemingly risky move, internal testing at Recursion shows brightfield imaging yielding comparable or even superior results in predicting drug perturbations.

Unraveling the PPG Wave 2.2 & 2.3: An 8-bit vs. 12-bit DAC Mystery

2024-12-15

This article delves into the subtle yet significant differences between the PPG Wave 2.2 and 2.3 synthesizers. While the 2.3 utilizes 12-bit DACs, wavetable playback remains 8-bit; only samples imported via external devices fully leverage the 12-bit precision. Oscilloscope measurements reveal a unique audio processing method: two oscillators send data interleaved, resulting in a DAC output frequency double the individual oscillator sample rate. This creates a distinctive timbre and high-frequency aliasing beyond human hearing. The article also notes the relatively slow CV update rate, yet the sound retains its character.

Anthropic's Model Context Protocol (MCP) aims to connect LLMs with external tools and data, allowing apps like Claude Desktop to access databases, search engines, and more. While MCP offers exciting possibilities for expanding AI application functionality, its current implementation has shortcomings. Claude Desktop only supports local servers, lacks robust handling of complex inputs, and suffers from client-side timeouts. Furthermore, improvements are needed in documentation and configuration, such as an official registry, support for asynchronous task scheduling, and multi-client collaboration, to fully realize MCP's potential for users.

White House Near Collapse: An Unprecedented Reconstruction

2024-12-14

In 1948, the White House, worn down by war damage and hasty renovations, faced imminent collapse due to structural decay and inadequate foundations. President Truman and his family were relocated, initiating a three-year comprehensive reconstruction. This project not only repaired the critical structural issues but also modernized the White House, adding basements, expanding utility spaces, and nearly doubling the number of rooms. A secret atomic bomb shelter was also constructed, reflecting the anxieties of the Cold War era. While the renovated White House was modernized, the removal of original interior elements altered its historical character.

Literary Review: The Achievements and Limitations of the 20th-Century Novel

2024-12-15

Edwin Frank's new book, *Stranger Than Fiction: Lives of the Twentieth-Century Novel*, explores the accomplishments of the 20th-century novel. Frank argues that novels, through formal innovations like Kafka's rambling sentences and Stein's repetitions, guide readers to slow down and savor the nuances of language. He praises novelists' efforts in expressing collective experiences, particularly the horrors of war and the awakening of self-awareness, but also points out the book's Eurocentric perspective, its insufficient attention to novels from other cultural backgrounds, and its somewhat superficial exploration of war and self-awareness.
