Modern applications often need to access data from various databases, and PostgreSQL's Foreign Data Wrapper (FDW) allows users to query these external databases as if they were native tables. When combined with pg_cron for scheduling and stored procedures for automation, it creates effective archival pipelines. This post outlines the setup of FDW for connecting to external databases, importing foreign schemas, creating archival policies, and automating tasks. Key highlights include: - FDW is an extension based on the SQL/MED standard

Service discovery enables automatic connection and communication between services in microservices architecture, where components are deployed separately and may have dynamic IP addresses and ports. Unlike traditional monolithic applications, microservices require a means to find each other without hardcoding locations. A service registry acts as a central database that stores details about available services and their instances, including IP addresses, ports, and health status. Services register themselves with the registry and send regular heartbeats to confirm their availability. There are two types of service discovery

The feedback from users is valued and carefully considered. The content discusses an experimental data structure called a sparse vector with a tree-like design that uses bitmasks for quick intersections. This approach enhances the efficiency of element-wise multiplication, which is crucial for dot products and matrix multiplications, particularly when dealing with vectors that have large gaps or discontinuities. The structure features fixed depth for terminal nodes, optimizing performance and enabling branch-free access to zero values. It boasts O(1) random access speed,

The content discusses feedback analysis, emphasizing the importance of user input. It also introduces a bash script called "chatgcc.sh" that enables users to utilize ChatGPT as a C compiler by generating x86_64 assembly code saved as "test.asm." The script attempts to assemble and link this file to create an executable program named "test." Additionally, the script includes adjustable variables for the prompt and model used in the OpenAI call. Users are directed to documentation for more qualifiers.

The author, a professor and researcher in operating systems, describes MINIX as a personal hobby that he pursues in his spare time. He shares insights about the future of operating systems, focusing on two main designs: microkernel and monolithic systems. Monolithic systems, like UNIX and MS-DOS, have everything bundled into a single file that operates in kernel mode, while microkernel systems run most of the OS as separate processes that communicate via message passing. Examples of microkernel systems include RC

An international team of geochemists has discovered the reason gold often appears alongside arsenic, providing insight into the formation of gold deposits. During their presentation at the Goldschmidt Conference, researchers explained that while gold can exist as nuggets, a significant amount is found in combination with iron and arsenic minerals like pyrite and arsenopyrite, which can concentrate gold up to a million times more than normal. Using intense X-ray beams, the team studied how arsenic-enriched minerals allow gold to bind

The OpenFalklands blog discussed recent developments in telecommunications, specifically regarding Starlink usage in the Falkland Islands. On February 7th, Starlink users began facing service terminations as their 60-day roaming period expired, highlighting ongoing frustrations with internet access. Despite a significant demand for Starlink services—evidenced by a petition signed by 70% of the island's residents to reduce a high VSAT license fee and to formally authorize Starlink—the service remains illegal due to Sure International

The document discusses the integration of a system into VSCode's remote editing capabilities over SSH, particularly in the context of using language models (LLMs) for code generation. It highlights the phenomenon of "hallucination," where LLMs produce incorrect code. The proposed solution is to create a closed-loop system where an "Agent" runs generated code, captures errors, and feeds them back to the LLM for iteration, ideally on a clean Linux instance to avoid system configuration issues.

The content discusses challenges faced by operations (ops) teams in managing manual procedures, particularly in modifying infrastructure and provisioning user accounts. These procedures can become complex, lengthy, and frustrating, often described as "slogs." While automation is a potential solution, automating individual steps often leads to a proliferation of single-purpose scripts without reducing overall complexity. The key issue is the perception of futility in automation efforts. A proposed solution is "do-nothing scripting," which involves encoding each step of a slog into

The content discusses the concept of "Ruby Programmer Happiness," which refers to the fulfillment software engineers experience when they can effectively deliver business value to customers while maintaining code with minimal effort over time. It emphasizes that true programmer happiness is derived from serving customers well, rather than simply enjoying a particular technology. The author suggests that many programmers prioritize personal enjoyment in their work over customer satisfaction, leading them to choose less effective programming languages over Ruby. Ruby is portrayed as more productive in delivering value compared to other languages like Java
