The post discusses lessons learned from developing and maintaining large distributed systems, particularly regarding challenges that arise when scaling beyond a single container architecture. A key issue highlighted is the competition among multiple services for resources in a shared cache cluster, which can lead to significant debugging difficulties, especially when eviction policies result in key loss for one or more services. The impact of losing keys may vary between services, complicating the diagnosis of problems. Although it's easy to scale a cache cluster as a solution, the author prefers not to

The article expresses disappointment with Synology's decision to lock its upcoming 2025 Plus NAS models to using only its branded hard drives. The author notes that this marks a decline from earlier, more innovative hardware offerings. In 2021, Synology began restricting drives for new NAS units, particularly in the enterprise segment, which has made it harder to recommend their solutions compared to competitors like QNAP and iXsystems, who have advanced their technology with ZFS support and better hardware.

The content emphasizes the importance of feedback and details a method for building JavaScript views without frameworks such as React or Vue. Titled "Writing JavaScript Views the Hard Way," this approach aims to create maintainable and performant views while avoiding common pitfalls associated with low-level imperative code. The document suggests that this technique favors directness over abstraction, providing a structured way to develop views. It begins with a simple "hello world" example and outlines the components and exports of a view. The view's template

In April 2025, it was reported that issue 99108, opened in November 2022 on Python's GitHub repository, has been resolved. The issue highlighted the need for Python to adopt verified code for its hash-related infrastructure following a CVE in its SHA3 implementation. As a result, all hash and HMAC algorithms in Python are now provided by the verified cryptographic library HACL*, with 15,000 lines of verified C code included in Python's repository. This transition

The article discusses the concept of feature flagging in software deployment, highlighting its advantages over traditional methods. Feature flags allow developers to wrap new features or significant code changes in conditional statements, enabling them to deploy code that includes both critical bug fixes and new features without exposing the latter until they're ready. This approach mitigates the risks associated with deploying new capabilities, as developers can turn features on or off as needed, instead of rolling back entire releases that contain multiple updates. The author emphasizes the need to shift the

The content discusses the concept of lockless programming, which allows multiple threads to safely share changing data without the overhead of locks. While it seems beneficial, lockless programming is complex and can sometimes fail to deliver the expected advantages, particularly on platforms like Xbox 360. It emphasizes the need for a thorough understanding of the underlying hardware and compiler when using lockless techniques, as well as careful performance measurement to ensure they offer actual gains. The article suggests that simpler solutions, such as reducing the frequency of

The content discusses the challenges faced by Sequin in developing a sandboxing solution for their new transforms feature, which allows users to write functions for transforming and routing database messages. The team needed to balance performance, security, and usability, while also considering practical constraints as a startup. They explored various sandboxing approaches, including cloud functions and custom interpreters, evaluating them against key criteria and analyzing their pros and cons. Virtual machines are highlighted as commonly used for sandboxing due to their robust isolation features, though

Gottfried Leibniz, a 17th-century polymath known for inventing calculus, actuarial tables, and the mechanical calculator, aspired to create a "characteristica universalis," a perfect language that would encapsulate all scientific truths. He believed this language could simplify discovery to the level of crafting grammatically correct sentences, ensuring clarity and eliminating ambiguity. This dream parallels modern programming languages, which, while not embodying the entirety of knowledge, represent the binary system (also a Leib

GPU programming is evolving from complex environments dominated by C++ and vendor-specific toolchains to more accessible modern languages like Rust and Zig. This post examines Zig's GPU backend capabilities, particularly regarding Vulkan, OpenCL, and native instruction set architectures (ISAs). After four years of development, Zig's self-hosted SPIR-V backend is now sufficiently advanced to support basic shaders and compute kernels. Zig can generate PTX and AMDGCN code using LLVM, allowing developers to create high-performance GPU applications without

Good Friday, commemorated annually on the Friday before Easter Sunday, marks the crucifixion of Jesus Christ, a pivotal event in Christianity despite its painful nature. Christians refer to it as "good" to signify its holiness and the monumental implications it has for sin absolution and human relationships with God, rather than implying a joyful occasion. The day is observed through events detailing Christ's suffering, including his arrest, flogging, and crucifixion, leading to his burial in a tomb. The term

The article discusses the size of packets in packet-switched networks, highlighting that while these networks have been in use for decades, the optimal packet size remains a debated topic. Currently, the default packet size in the Internet is between 20 and 1,500 octets. Packets larger than this can face fragmentation issues, while those smaller may compromise header integrity. Historical context is provided, noting that in 1981, the Internet Protocol Specification (RFC 791) recommended a maximum packet size of
