Software development grapples with complexity, and developers strive to simplify challenging problems, leading to a concept called “self-trivialisation.” This involves creating solutions that abstract complexities, allowing tasks to become as simple as a single function call or library import. Essentially, developers aim to solve problems once, reducing the need for future efforts in that area. There are two approaches to software design: one focuses on simplicity to eliminate deficiencies, while the other complicates design to mask flaws. Self-trivialisation embraces the

A 67-year-old man named Tim Andrews is thriving more than six months after receiving a genetically modified pig kidney, marking a significant achievement in xenotransplantation—the transplant of animal organs to humans. The surgery, performed in January, has allowed him to remain dialysis-free after suffering from end-stage kidney disease. Andrews was one of three patients to receive these pig kidneys from the biotechnology firm eGenesis. Experts view the six-month survival as a pivotal moment, as this period is fraught with complications such

AWS S3 is a highly scalable, multi-tenant storage service that operates at an extraordinary scale, handling over 400 trillion objects and 150 million requests per second, with peak traffic exceeding 1 petabyte per second. Its durability and high availability come at a low cost. The foundation of this scale is based on hard disk drives (HDDs), which, despite being an older technology with limitations in input/output operations per second (IOPS) and latency, offer exceptional cost efficiency and

The provided content discusses the relationship between mathematics and programming, specifically focusing on type theory and equality. It explains how mathematical structures like natural numbers can be represented in programming languages like Haskell, but highlights the challenge of encoding laws that govern these structures due to different types of equality: definitional equality and propositional equality. Definitional equality is straightforward and part of the definition, while propositional equality requires formal proof, which can be more complex. In traditional mathematics, equality is treated as a binary

Elephantshark is an open-source Ruby script developed by Neon that facilitates monitoring, understanding, and troubleshooting Postgres network traffic. It acts as a middleman in the Postgres-protocol exchanges, logging and parsing messages between Postgres servers, clients, drivers, and poolers. Unlike Wireshark, which can struggle with SSL/TLS-encrypted connections, Elephantshark can decrypt and re-encrypt these connections while logging the data. It also offers compatibility for Wireshark by providing SSL

On September 24th, the crates.io team was alerted by Kirill Boychenko from the Socket Threat Research Team about two malicious crates that were searching for Ethereum and Solana private keys, as well as arbitrary byte arrays for exfiltration. These crates executed harmful code at runtime, while imitating legitimate crates via typosquatting, copying their source code and documentation. The malicious crates were promptly disabled and deleted from crates.io, with logs retained for further investigation. They functioned similarly to

The post discusses JDK 25, the latest Long-Term Support (LTS) release, and highlights its new AOTCache (ahead-of-time cache) feature, which optimizes code for future executions and could significantly enhance JRuby's performance. The author emphasizes that the primary challenge in migrating to JRuby has been its slow startup time, a problem that hasn't been fully addressed despite ongoing improvements. While JRuby has made strides in optimizing memory allocation and deferring initialization, its startup times remain significantly

The article explores the idea of using PostgreSQL for caching instead of Redis by implementing a simple HTTP server that interacts with both databases. The author sets up an experiment on a Kubernetes cluster to compare performance, using unlogged tables in PostgreSQL and standard Redis settings. Both databases are seeded with 30 million entries. The testing involves benchmarking operations (gets and sets) for metrics like operations per second, latencies, memory, and CPU usage. The benchmarks simulate real scenarios with different probabilities for hits and misses
