The article introduces a "super-flat AST" representation for the
simpprogramming language, achieving significant performance and memory usage improvements over traditional tree-based ASTs by leveraging contiguous memory allocation and compact node representations. This optimization has substantial implications for compiler design, suggesting that carefully engineered data structures can dramatically reduce memory footprint and improve parsing speed, especially when dealing with large codebases.The author explores several AST optimization techniques, starting with string interning to reduce memory usage by sharing identical strings, followed by flat ASTs using pointer compression to store nodes in contiguous arrays, and then bump allocation to amortize allocation costs. The "super-flat AST" takes this further by packing node metadata and child indices into a compact 8-byte structure, using macros for code generation, and employing unsafe Rust to bypass lifetime limitations. Benchmarks demonstrate that the super-flat AST achieves a 3x reduction in memory usage and a corresponding increase in parsing speed compared to traditional tree representations, highlighting the effectiveness of contiguous memory layouts and compact data structures in compiler performance.

The Go proposal introduces new metrics in the
runtime/metricspackage to provide insights into goroutine scheduling, including the total number of goroutines, their states (running, runnable, waiting, not-in-go), and the number of active threads. These metrics will enable developers and observability systems to more effectively identify and address performance bottlenecks, lock contention, and scheduler issues in Go applications, leading to improved application performance and stability.The
runtime/metricspackage will be enhanced with counters for goroutine states and thread counts, which can be tracked to spot regressions and scheduler bottlenecks; specifically, the new metrics include/sched/goroutines-created:goroutinesfor total goroutines,/sched/goroutines/not-in-go:goroutinesfor goroutines in syscalls or cgo,/sched/goroutines/runnable:goroutinesfor goroutines ready to execute,/sched/goroutines/running:goroutinesfor goroutines executing,/sched/goroutines/waiting:goroutinesfor goroutines waiting on resources, and/sched/threads/total:threadsfor the count of live threads owned by the Go runtime, all as uint64 counters. An example is provided to demonstrate how to read these metrics usingmetrics.Read, allowing developers to monitor and analyze goroutine behavior in their applications. - debug 2025-11-25 17:18:48
The article discusses the history and eventual failure of the .us domain and its locality-based naming scheme (RFC 1480), which aimed to create a hierarchical DNS structure based on US geography and political divisions. This failure highlights the tension between the technical desire for structured naming and the practical limitations of user-friendliness and bureaucratic inertia in the evolution of internet infrastructure.
The initial vision behind .us was to create a structured, hierarchical domain system mirroring the US's political geography, with domains like
ci.portland.wa.usfor city governments andk12.state.usfor school districts, as formalized in RFC 1480. However, this system was undermined by several factors, including the increasing automation and privatization of DNS management, the federal government's preference for the simpler.govdomain, and the general public's difficulty in understanding and remembering deeply hierarchical names; while the RFC 1480 names are still around, they are considered legacy and are slowly being phased out. - debug 2025-11-25 17:18:42
Object-oriented programming (OOP) is a broad paradigm with varying interpretations, and this article surveys the core ideas associated with OOP, discussing the trade-offs of each. Understanding these nuances is crucial for making informed decisions about software design and avoiding the pitfalls of blindly following "best practices" that may not be suitable for every situation.
The author breaks down OOP into key concepts like classes, method syntax, information hiding, encapsulation, interfaces, late binding, dynamic dispatch, inheritance, subtyping polymorphism, message passing, and open recursion, providing insights into the advantages and disadvantages of each; for example, while inheritance can be convenient for code reuse and dynamic dispatch, it can also lead to performance overhead, rigid hierarchies, and violations of the Liskov substitution principle, and encapsulation, while promoting self-contained objects, can hinder data locality and parallelism. The author also touches on common OOP best practices, such as preferring polymorphism over tagged unions, making data members private, and favoring extension over modification, and the author argues that these practices involve trade-offs that should be carefully considered rather than blindly adopted.

The author argues for the adoption of dependency cooldowns, a waiting period between a dependency's publication and its integration into a project, as a simple and effective method to mitigate the majority of open-source supply chain attacks. Implementing dependency cooldowns can significantly reduce exposure to compromised dependencies, incentivize responsible behavior from supply chain security vendors, and prompt packaging ecosystems to incorporate cooldowns directly into package managers.
The argument is based on the observation that most supply chain attacks have a short window of opportunity (hours or days) between the introduction of malicious code and its detection/removal, while the time to compromise a project can be much longer. By implementing a cooldown period (e.g., 7-14 days), developers can avoid most attacks, as security vendors have time to identify and report compromised packages. This approach is easy to implement using existing tools like Dependabot and Renovate, and it encourages vendors to focus on rapid detection rather than overhyping vulnerabilities.

The author argues that the terms "fast" and "slow" are often useless and even detrimental in programming due to the vast range of magnitudes software operates within. This imprecision can lead to miscommunication, mismatched expectations, and ultimately, flawed architectural decisions that can significantly delay or derail projects.
The article highlights that software engineering deals with performance considerations spanning approximately 19 orders of magnitude, making the subjective terms "fast" and "slow" inadequate for precise communication; for example, a web framework benchmarked at 10,000 requests per second might be irrelevant if the code within each request takes 50ms, capping throughput at 20 requests per second per core. The author suggests that developers should focus on specific metrics, competitive comparisons, and the time order of magnitude when discussing performance, and further cautions against premature optimization, where developers obsess over nanoseconds while neglecting milliseconds, and advocates for order-of-magnitude reasoning to identify the true performance bottlenecks in a system.

The author demonstrates the practical utility of garbage collection (GC) theory by applying the principles of reference counting, a GC technique focused on identifying dead objects, to optimize incremental parsing in a text editor. This approach significantly improves performance by avoiding the need to traverse the entire document to identify nodes that are no longer in use, which is crucial for efficient bidirectional updates between the text and rich text versions.
The problem arose when using Ohm for incremental parsing in a ProseMirror-based text editor, where tracking changes between document versions required identifying nodes that were present in the old document but not in the new one. Initially, a tracing-based approach was used, which involved traversing the entire document to identify live nodes, negating the benefits of incremental parsing. Drawing inspiration from "A Unified Theory of Garbage Collection," the author implemented a reference counting mechanism to identify dead nodes, which only required visiting the nodes that were not reused in the new document. This optimization drastically reduced the processing overhead, making the bidirectional updates more efficient by focusing only on the nodes that were actually affected by the edit.
