In the previous post, we discussed how the compiler converts optimized SSA into machine code and packages it into object files, with each file containing compiled code for a specific package. However, programs consist of multiple packages that are independently compiled into their own object files, which cannot run by themselves. This is where the linker plays a crucial role by combining these object files into a single executable file that the operating system can execute. The linker undertakes four primary tasks: 1. **Symbol Resolution**: It resolves

The content emphasizes the importance of user feedback and highlights the features of Rugo, an agent product driven by Opus 4.6, which combines Ruby-like syntax, Shell power, and Go binaries. It suggests that as software abundance grows and agents start composing code, the significance of programming languages may diminish. It also issues a warning about the experimental nature of Rugo, likening its reliability to an experiment that could potentially fail. Lastly, it invites users to check documentation for available qualifiers.

Elizabeth from SigNoz introduces a newsletter focused on observability, OpenTelemetry, open-source, and related engineering topics. The team at SigNoz, passionate about these areas, aims to share valuable insights and encourages subscriptions. The piece discusses the use of OpenTelemetry, highlighting auto-instrumentation as a powerful tool for observability. However, it warns that while auto-instrumentation captures comprehensive telemetry, it can lead to excessive data, creating noise that obscures actionable insights. This surplus often stems

The article discusses the historical and ongoing relevance of quartz crystals in radio technology, beginning with their use in the 1920s and their mass production during World War II, initially sourced from natural Brazilian quartz. Today, over 2 billion quartz crystals are produced annually, predominantly serving as clocking mechanisms for microprocessors. The text emphasizes the critical role of quartz crystals in ensuring stability in oscillators, noting a significant incident in 1972 where a train crash was attributed to a faulty crystal oscillator. Quartz

The document discusses the Hierarchical Navigable Small Worlds (HNSW) algorithm, a popular method for approximate nearest neighbor search. The goal of this algorithm is to efficiently find the nearest vector to a given query vector within a large dataset of vectors. A brute-force approach is impractical due to the potential size of the dataset, which can contain billions of vectors and high dimensionality (up to 4096 dimensions). To optimize the search, HNSW leverages a data structure that represents "

In the second episode of the series "Behind The Screen," the focus is on web crawlers, essential software that significantly enhances tech by enabling search engines to display results. The episode discusses the core concept of web crawlers, which systematically browse the internet to download and index content from websites, creating databases for search engines. Instead of delving into specific implementations by companies like Google or Yahoo, the episode outlines the general workings of web crawlers. The process begins with a Crawl Manager, which receives a

Amit Prasad expresses his long-standing passion for writing “Good Code™”, which he defines as code that is easy to read, maintain, and serves a specific purpose. He emphasizes that good code arises from a mix of talent, experience, passion, and time investment, yet notes that it is quite rare. As a software engineer, Prasad clarifies that his role is not strictly about writing good code but creating software that effectively solves problems. He shares an anecdote about a colleague at Modal

The content discusses a community trust management system based on explicit vouches to facilitate interactions within a project. Participants must be vouched for to access certain project areas, and they can also be denounced to restrict participation. The system is designed to be generic and easily applicable to any project, with built-in integration for GitHub. Trust can be expanded through interconnected vouch lists across projects, allowing users deemed trustworthy in one project to be trusted in others. This system is currently experimental, implemented by Ghostty

The author expresses a generally positive view of AI but critiques "agentic coding," stating it often does not enhance productivity and can reduce user comfort with codebases. This conclusion is based on personal experiences, interviews with job candidates who performed poorly when using such tools, and research studies that show users of agentic coding do not achieve better outcomes. While the author sees potential for improvement in agentic coding, they assert it currently harms software development. Instead, the author advocates for exploring alternative AI solutions in software
