The author began using Docker in 2018 to run TensorFlow on an old computer and found it a useful way to execute Linux utilities on Windows. Intrigued by different virtualization strategies, especially Docker's containerization, the author compiled a blog detailing these learnings from a foundational perspective, starting from low-level components involved in container execution. The blog explains that containers implement OS-level virtualization by encapsulating applications and their dependencies, ensuring consistent execution across environments with minimal overhead. The distinction between images (static

RudderStack has launched Snowflake Streaming, a feature that enables faster integration of customer data into Snowflake. The company shares insights from their experience of using PostgreSQL as a streaming engine and queuing system instead of alternatives like Apache Kafka. This decision was based on PostgreSQL's flexibility, reliability, and ease of debugging. Over six years, they successfully scaled their system to handle 100,000 events per second by addressing challenges such as table bloat and index bottlenecks. The post provides

The topic of logging in software engineering is complex, with various valid perspectives depending on the situation. The author advocates for time-based logging—logging every X seconds—over count-based logging, which logs every X messages. Time-based logging ensures a consistent log emission rate, regardless of the application's message processing speed, which can vary significantly between production and testing environments. The author emphasizes that while logging too much can be problematic, not logging enough can lead to missed insights, making time-based logging a more effective default

This spring, XBOW developed a novel approach that significantly improved the performance of its vulnerability detection agents, increasing success rates from 25% to 55% on fixed benchmarks with limited iterations. XBOW functions as an autonomous penetration tester (pentester) that finds vulnerabilities in websites without ongoing human intervention after initial setup. The pentesting process involves creating and updating a mental model of the website's structure and potential attack points. A particular focus of the development was a subagent dedicated to identifying specific vulnerabilities,

DeepSeek, a relatively unknown Chinese AI company, launched a chatbot called R1, claiming it rivals outputs from well-known AI firms while significantly reducing computational costs. This announcement led to a notable drop in stock prices for major Western tech companies, especially Nvidia. There were allegations that DeepSeek may have used knowledge distillation to obtain insights from OpenAI's proprietary model without permission, sparking shock within the industry. However, distillation is a common technique in AI development, well-established in the research community

Dennis Ritchie was a pivotal figure in the development of modern computing, known primarily for creating the C programming language and significantly contributing to the UNIX operating system. In the early 1970s, programming was cumbersome due to the reliance on machine-level assembly language. Working at Bell Labs, Ritchie sought to create a more efficient programming language to assist in building UNIX. He improved upon an earlier language called B, ultimately developing C, which offered speed, efficiency, and the ability to easily port UNIX across

The author, a programmer with a passion for Emacs and a fondness for parentheses, reflects on their unexpected return to .NET after a 15-year break. Previously, they had chosen Java for its portability over .NET, despite some advantages in the latter. Recently, their interest in OCaml led them to discover F#, a functional programming language developed by Microsoft for .NET. F# aims to enable writing concise, robust, and performant code while keeping the focus on problem-solving rather than programming
