The post discusses advanced features of protocol buffers (protobuf), focusing on packed repeated fields, maps, and negative numbers. Repeated fields allow multiple values of the same type in a single field, with each value typically encoded as separate tag-value pairs. Packed repeated fields offer a more efficient encoding option for numeric types, allowing multiple values to be stored in a single length-delimited field. Maps in protobuf represent repeated key-value pairs, with each entry encoded as an embedded message. For encoding negative numbers,

The content discusses the various options available for message queues in distributed architectures, highlighting different types of communication methods (asynchronous vs. synchronous), queue designs (FIFO vs. priority and delay queues), and broker types (intelligent vs. minimal). The author seeks insights from individuals who have built production systems about their experiences with different message queues, including choices made, challenges faced, and any regrets related to adding complexity. The conversation reflects a mix of technical considerations and emotional biases toward certain technologies, with references to

The author reflects on their experience with programming languages from the 1990s, particularly comparing their use of Visual Basic to a colleague's use of Delphi, which allowed for the creation of standalone programs. They express jealousy over Delphi's features, particularly its ability to compile without requiring a runtime. Fast forward to 2024, the author revisits Pascal and Delphi while searching for ways to compile code across multiple platforms and discovers Lazarus, an open-source cross-platform alternative to Delphi, allowing compilation on systems

The content discusses the importance of defining macros carefully in C programming to avoid unexpected behavior. It specifically highlights the use of the `do { ... } while(0)` construct in macros, commonly seen in Linux kernels and other C libraries. According to Robert Love from Google, this construct allows macros to operate consistently, particularly with regards to semicolons and nesting in `if` statements without curly brackets. The article explains that without `do/while(0)`, multi-statement macros can lead

The blog emphasizes the importance of maintaining its content and encourages support from readers. It discusses the modern demands of software development, such as high velocity and reliability, and highlights how elite engineering teams excel by adopting best practices like shift-left testing. A key tool mentioned is Testcontainers, which allows developers to run integration tests using real dependencies in disposable Docker containers. The post argues that traditional CI/CD practices often delay integration testing, leading to challenges such as undetected bugs and environment inconsistencies. Shift-left testing,

The content discusses "muscle-mem," a Python SDK designed for AI agents to enhance efficiency in task execution by caching learned behaviors. This behavior cache records the agent's interactions with tools as it solves tasks and can replay those interactions when similar tasks arise, thus reducing the need for the AI to recompute repetitive actions. The main goals are to decrease execution time, minimize variability, and eliminate unnecessary token costs. Muscle-mem allows for flexible integration of agents and focuses on safe tool reuse through

A recent survey by Tricentis highlights the impact of AI coding assistants on software development, significantly speeding up coding processes but also introducing new risks. While almost two-thirds of teams rush code releases without full testing to meet deadlines, over 80% of IT leaders believe AI can enhance both speed and quality, with almost 90% already seeing returns on generative AI investments. Despite this optimism, 66% of organizations anticipate a major outage within the next year, indicating that reliance on AI for approvals

Internal Developer Portals (IDPs) are currently marketed as essential tools for engineering teams, offering resources like service catalogs and team performance metrics. However, many IDPs act more as passive portals that simply display information rather than as dynamic hubs that streamline workflows and reduce developers' workloads. This can lead to increased cognitive load without significantly enhancing productivity, especially given that developers often face tight deadlines. Additionally, many IDPs face a producer-consumer issue where developers, who do not see immediate benefits, neglect to

The article discusses the advantages of using a reverse proxy server like Nginx or Thruster to serve large files in a Rails application. It introduces the X-Accel-Redirect (or X-Sendfile) HTTP header, which allows the web server to deliver files directly to clients, streamlining the process and reducing memory overhead for the Rails app. Instead of the app reading large files into memory, it handles authentication and permission checks, then instructs the web server to stream the file directly to the
