The write-up discusses the "behavioral analysis" of `shared_ptr<T>` in GNU's libstdc++, a smart pointer that manages shared references to a single underlying pointer by tracking the reference count. This ensures the pointer is only freed when the last reference is destructed, making it particularly useful in multi-threaded applications due to its atomic reference count tracking. The author contrasts the performance of a Rust implementation of an immutable Red-Black tree insertion with that of C++, noting that the Rust version

The author is seeking advice on reducing the size of an ARM64 executable without lowering optimization levels due to performance constraints. They are already using techniques like Profile-Guided Optimization (PGO) and Inter-Procedural Call (IPC) to minimize executable size. They inquire about features such as machine outlining and machine splitting to further optimize size and whether these are enabled by default. The text details the author's findings from profiling tools like bloaty, which indicate that the text section is the largest part of

The document discusses a serious security incident involving malicious versions of the nx package and related plugins that were published to npm. These versions contained harmful code that could scan users' file systems, collect credentials, and upload them to GitHub under the users' accounts. The problematic versions were removed from npm at multiple times (10:44 PM EDT and 6:20 AM EDT). The vulnerability originated from an insecure workflow that allowed for the injection of executable code. Although the workflow was reverted shortly after the team

The content discusses the tendency of people to be overly confident in their opinions and decisions, particularly in the tech industry. It argues that while humility is valuable, it often leads to the frustrating need to say "it depends" when reaching a Senior level in software development. In contrast, higher level positions allow for more confidence in decisions, which is appealing. The author then critiques programming practices that fail to account for uncertainty, using GPS coordinates as an example of imprecise data. They highlight a paper by

The author is affiliated with the School of Computing at the University of Kent, focusing on programming language implementation, complex concurrent systems, and tooling. Their research aims to enhance interpreter performance, detect and prevent concurrency bugs at runtime, and improve developer tools using modern language runtime systems. Interestingly, while much research seeks to optimize program speed and resource usage, the author discusses the utility of intentionally slowing down programs. This method can be beneficial for uncovering race conditions, simulating performance improvements, and assessing profiler accuracy.

The author reflects on their long-standing awareness of the programming language Forth, which they first encountered while studying embedded hardware two decades ago. Initially perceiving Forth as a "weird language," the author did not engage with it until June of the current year, when they decided to explore it more deeply and implement two versions of it during their free time. The author distinguishes between two levels of Forth: user-level Forth, comparable to Lisp without macros, and hacker-level Forth,

As of early 2025, the organization is deploying applications using Kamal and Docker as their containerization platform. They moved away from external container registries, such as Dockerhub and Amazon's Elastic Container Registry, during their transition to a more self-hosted solution. After evaluating options, they chose Harbor for its robust feature set and ease of setup within Kubernetes environments. Their initial plan for version 1 of the on-premise registry includes utilizing their Pure FlashBlade storage cluster with S3-compatible

The article emphasizes the importance of testing in software development, particularly within frameworks like Agile, TDD, and BDD. It points out a widespread belief among developers that deleting tests is unacceptable, arguing instead that this belief is misguided and can be detrimental. The core purpose of writing tests is to ensure that software functions as expected and to provide confidence during the development process. Without tests, developers risk creating a chaotic situation where changes lead to unintended problems, making it harder to maintain software quality. Ultimately, the
