The author discusses the decision to eliminate all `strncpy()` calls from the curl source code, describing it as a problematic function due to its non-null termination and zero-padding behavior. They argue that most codebases would benefit from avoiding `strncpy()` entirely, opting instead for safer string handling practices that either fully copy strings or indicate an error. The author acknowledges that while `strcpy()` has valid uses and a clearer API, it carries risks if buffer size checks are not properly maintained during code updates

The content discusses the concept of domain-driven design (DDD), emphasizing its focus on aligning software development with business requirements rather than just technical needs. A key element of DDD is the bounded context, which helps delineate domains, guiding team structuring and defining service boundaries, particularly important in microservice architecture. The article notes a disconnect in analytics, where datasets and pipelines are often delivered without clear interfaces or guarantees, leading to trust issues regarding data accuracy.

The content discusses a zero-copy PDF text extraction library called zpdf, written in Zig. It features high-performance, memory-mapped parsing with SIMD (Single Instruction, Multiple Data) acceleration and highlights its impressive performance metrics, achieving a peak throughput of 45,000 pages per second on an Apple M4 Pro. The library outperforms MuPDF's text extraction, being 650 times faster than Tika, with better accuracy metrics established against MuPDF, which serves as a reference for accuracy.

The author reflects on the significant impact weather has had on their life, particularly during their time as a young athlete and later in navigating travel decisions. Their grandfather, an avid follower of weather patterns, inspired the creation of FediMeteo, a project to provide regular weather updates. The idea emerged while checking the holiday forecast, leading the author to register a domain and plan the project. They chose FreeBSD jails for managing different country instances of the service. Initially doubting the project's interest level

Stephane shares insights for Engineering Managers on improving the hiring process for senior engineers. He emphasizes that traditional interviews often focus too much on algorithmic problems and coding exercises, neglecting critical real-world skills such as navigating complex codebases, explaining technical decisions, and communicating effectively with stakeholders. These skills are essential for a senior engineer's daily tasks but are not assessed in standard interview formats. As a result, companies may end up hiring individuals who excel in interviews but may not succeed in the role itself. He

Libsodium has reached its 13th anniversary, created to fulfill Dan Bernstein's vision of simplifying cryptography. The project focuses on providing high-level APIs that abstract away complex algorithms, ensuring users can utilize cryptography without needing to understand the underlying details. The developer emphasizes the importance of maintaining stable APIs, even if they could have been designed differently in hindsight. Although Libsodium aimed to offer high-level functions, many users began to utilize lower-level functions directly, which diverged from its original intent

Over the past year, a series of interviews with expert tech bloggers focused on sharing insights and advice for new bloggers. The interviewees were asked the same questions, leading to a variety of insightful responses. A recurring theme in their advice for beginners is to write without overthinking it. They suggest writing about personal projects or problems they are passionate about, as this often resonates with readers. New bloggers should focus on regular writing to build their skills, accepting that initial readership may be low. As confidence grows,

A serious issue occurred when all servers in production crashed within 90 seconds due to a single malformed HTTP request causing a segmentation fault in the application. This triggered a chain reaction where the load balancer marked the failed server as unhealthy and retried the same request on subsequent servers, leading to a rapid cascade failure across all servers. Typically, load balancers retry failed requests multiple times (often three), resulting in four total attempts, which exacerbates the problem as each retry targets a different server. In one

A recent Substack post by Skilled Coder on Java data structure performance highlighted significant findings from conducting 10 million operations, particularly regarding insertion and get operations. The post sparked curiosity about how these results compare to Eclipse Collections (EC), which has its origins in 2004 when it was developed by Goldman Sachs due to limitations in JDK's collections. EC offers enhanced functionality and better performance compared to standard JDK collections. Using the Java Microbenchmark Harness (JMH) to run benchmarks, it was

Scheduling background jobs within database transactions can lead to various issues in Rails applications, such as RecordNotFound or ActiveJob::DeserializationError due to jobs executing before a transaction commits. Rails 7.2 introduces a solution with the `enqueue_after_transaction_commit` method, deferring job enqueueing until transaction completion. In practice, scheduling a job, like sending a welcome email after user creation, may function well in development but fail in a production environment with faster job queues, where transactions may not commit

The InnoDB Storage Engine uses a specialized variant of the Least Recently Used (LRU) eviction algorithm to manage its cache, which consists of both on-disk structures (like tablespaces, redo logs, and undo logs) and in-memory structures (specifically the buffer pool). The buffer pool caches frequently accessed table and index pages in RAM to improve query processing speed, often utilizing up to 80% of a dedicated database server's physical memory. InnoDB enhances traditional LRU management by
