The author of the article discusses their experience with modifying their robots.txt file to prevent crawlers from accessing their website, resulting in unintended consequences. After implementing the change, they noticed that LinkedIn posts no longer displayed article previews and that engagement from connections decreased. Initially confused about the issue, the author discovered through LinkedIn Post Inspector that the new robots.txt directive blocked LinkedIn's bot from scraping their web pages. This prevented access to necessary meta tags for generating link previews, specifically Open Graph meta tags,

The content discusses the dynamic nature of software engineering, emphasizing that software systems are constantly evolving rather than being static entities. Unlike a bicycle, which can be maintained with minimal changes, software requires ongoing updates to meet changing user expectations and usage patterns. For instance, the transition from desktop to mobile has necessitated major overhauls in many software projects. As software developers embrace the concept of continual evolution, they adopt different design principles. Instead of rigid linkages, they favor creating APIs with well-defined contracts

The tech industry is seeing a significant downturn in 2025, with over 94,000 layoffs impacting 150 companies. Junior developers are particularly affected, as job openings for software developers in the U.S. have plummeted by more than 70%. In response, many new developers are turning to a concept called "vibe coding," which involves using AI to create applications without requiring traditional coding skills. This trend leads to a generation of developers who lack foundational coding knowledge, relying on AI for

The author reflects on the current state of web crawling, noting that although significant technological advancements have occurred since Michael Nielsen's 2012 post—such as more powerful CPUs, faster storage with NVMe drives, and expanded cloud computing options—challenges have also increased due to the rise of dynamic and content-heavy websites. To explore these changes, the author built and ran their own web crawler under specific constraints: a 24-hour runtime target (aiming to crawl a billion pages in a day) and

The content differentiates between scalability and performance, emphasizing that they are not the same. It introduces a simplified model to illustrate this, focusing primarily on throughput, as reducing latency is challenging and yields diminishing returns. In this model, "Jobs" represent tasks performed by servers, while "Boxes" represent units like VMs, containers, or processes that handle these jobs. The basic premise is that with one Box, performance metrics such as latency and throughput are directly linked, but adding more Boxes increases capacity and

Before the advent of user-friendly programming, software development was complex and limited to those proficient in machine codes and low-level instructions. Grace Hopper envisioned a simpler approach where programming could be done in plain English. This perspective revolutionized human-computer interaction, making programming more accessible. While Corrado Böhm theoretically developed the first compiler in 1951, it was Hopper's practical implementation in 1952 that made a significant impact. Her creation of the A-0 System, the first practical compiler, allowed

Researchers have discovered a new type of magnet called "altermagnets," which represents the first significant advancement in magnetism in nearly a century. Inspired by artwork, Libor Šmejkal, a key figure behind this discovery, proposed the existence of altermagnets in 2022, challenging the long-standing belief that only two types of magnetism existed. These new magnets have potential applications in developing a new type of computer, offering the possibility of faster performance, reduced energy consumption, and

Abiodun Olowode's article discusses two advanced Just-In-Time (JIT) compilers for Ruby: TruffleRuby and JRuby, including their advantages and disadvantages, along with a mention of the newly announced ZJIT compiler. The post explains JIT compilation as a hybrid of code interpretation and traditional compilation, highlighting how it optimizes performance by converting frequently executed code ("hotspots") into machine code during runtime. While JIT compilation allows for an initial slower performance that improves over time
