Neha, the founder of April, shares her journey of developing an AI executive assistant designed to manage inboxes, calendars, and meeting preparations effectively. The initiative was born out of a hackathon after Neha and her co-founder, Vedhsaka, sought to create something useful while preparing for a Y Combinator (YC) application, despite previously facing rejections. They developed a product called Inbox Zero, which allows users to manage emails via voice commands. After winning the hackathon, they

Martijn Braam discusses the challenges of managing IP address conflicts in embedded networks, particularly in portable setups like video racks that need to connect to various venues. Instead of randomly selecting subnets to avoid conflicts, Braam advocates using Virtual Routing and Forwarding (VRFs) or a dedicated router. This router allows devices within the rack to maintain a consistent internal subnet while using Network Address Translation (NAT) to manage external IP changes. However, conflicts can occur if the venue's public network shares

Chinese astronauts aboard the Tiangong space station have successfully developed a method for producing rocket fuel and breathable oxygen using a technique known as "artificial photosynthesis." This breakthrough, which mimics the natural photosynthesis process in plants, allows the conversion of carbon dioxide and water into useful products with basic equipment and minimal energy. The experiments, conducted by the Shenzhou-19 crew, could be instrumental for China's planned moon base, set to be completed within a decade. The technology, under development since

The UK's Online Safety Act (OSA) is raising concerns about free speech, as it imposes site-blocking powers that critics argue could lead to the censorship of legitimate content. The Act, while purportedly aimed at protecting children, has been criticized for making it difficult for adults to access various sites without proving their identity, effectively treating unverified adults like minors. Some large websites may choose to ban UK users entirely to avoid hefty fines for exposing children to inappropriate content. The OSA has drawn scrutiny for

This content introduces a series focused on understanding input/output (I/O) at a low level in computing. It emphasizes that the fundamental operations of reading and writing involve transferring data between buffers, which is essential for addressing complex system problems. The series aims to provide practical coding examples to illustrate these concepts, helping readers understand how various technologies like Nginx, Redis, Go routines, and NodeJS utilize I/O models. I/O is defined as the communication between a computer system and external entities, with inputs

ThreadSafe explores strategies for building robust software systems, focusing on the crucial concept of exactly-once semantics (EOS) in Kafka applications. EOS ensures that messages are processed a single time, avoiding duplicates, even amid failures. Kafka's architecture supports this by allowing atomic transactions for consuming, producing, and committing offsets. However, incorporating external systems like databases complicates achieving EOS. This article outlines a method to construct an end-to-end EOS pipeline using Spring Boot and Kafka, where messages trigger a state change in

The content describes an experience at the ocean where a child expresses frustration over the changing tide pools, wishing the ocean would stay in one state so she could finish counting hermit crabs. Despite her father's explanations about tides and the natural changes driven by the moon's gravitational pull, she desires stability. The narrator reflects on this situation as a metaphor for the challenges faced by software engineers, who also contend with constant changes in their work environment without external factors like the moon to blame. The piece references a talk

The content discusses a Rust programming challenge involving enums and their conversion to and from integers. The author highlights the ease of converting an enum to a number (e.g., using `SomeEnum::B as u8`) but notes the difficulty of converting a number back to an enum, as straightforward casting is not allowed without ensuring the number corresponds to valid enum values. They express a desire to create a simple function, `fn to_int(e: SomeEnum) -> u8`, that achieves this without complexity

The document presents an annotated version of the influential paper "Attention is All You Need," which introduces the Transformer model. The annotations include a line-by-line implementation with modifications and comments that help in understanding the concepts. The Transformer model is designed to reduce sequential computation, distinguishing itself from other neural network architectures like Extended Neural GPU, ByteNet, and ConvS2S, which utilize convolutional networks that operate on input/output positions more sequentially. In contrast, the Transformer allows for constant-time operations between

In a blog post from August 21, 2025, Paul Kafasis discusses an unexpected benefit that arose from a software bug at Rogue Amoeba. Initially, when Audio Hijack was launched in 2002, the team aimed to offer a 15-day free trial with unlimited usage. However, after the trial period, users would encounter restrictions, which did not encourage sufficient sales. After several updates, a bug in version 1.6 accidentally limited recording to just 15 minutes from

The author reflects on the criticism directed at new programmers, particularly with the rise of AI, and emphasizes the importance of supporting them rather than mocking their mistakes. They acknowledge that seasoned developers often forget their own early struggles when learning to program and question the harsh judgment faced by newcomers. The author recalls their own flawed beginnings in coding and argues that today's younger developers are navigating similar challenges. They assert that AI is not to blame for the perceived decline in code quality among new programmers and advocate for fostering a supportive environment

Big O notation is used to describe the performance of a function in relation to the growth of input size, rather than measuring time directly. It helps predict how programs perform across different input sizes. The post focuses on four common categories of Big O notation: constant, logarithmic, linear, and quadratic. An example is given with a JavaScript function that calculates the sum of numbers from 1 to n, illustrating how its execution time varies as n increases. When n is set to 1 billion (

Unicode is recommended for text fields in data structures or protocols, specifically using UTF-8 encoding. However, not all Unicode characters are suitable, prompting Paul Hoffman and the author to draft RFC 9839, which addresses "problematic characters." The RFC identifies characters that should be excluded and proposes three less problematic subsets for use. It provides important guidelines for software and networking professionals designing new systems with text fields. An example of a problematic character includes Unicode U+0000, which has no human-readable meaning
