Tailscale on Plan 9: An April Fool's Prank That Actually Worked

2025-04-02

Tailscale's April Fool's Day announcement wasn't a joke: they actually ported Tailscale to the Plan 9 operating system. The journey was fraught with challenges, including outdated Go compiler support for Plan 9, kernel issues, and inter-process communication bugs. The team even fixed a decades-old bug in the Plan 9 kernel. The project, initially a naive undertaking, evolved into a significant effort, culminating in a working demo running Tailscale on Plan 9, even showcased on a web browser. This wasn't just a prank; it was a testament to the team's technical prowess and a fascinating exploration of a niche OS.

Fake Deadlines: A Manager's Secret Weapon?

2025-04-02

This article explores the effectiveness of 'fake deadlines' in project management. Drawing on personal experience and the insights of James Stanier, the author argues that setting challenging deadlines leverages Parkinson's Law (work expands to fill the time available), boosting team efficiency and driving project progress. However, the author emphasizes that success hinges on team involvement, clear goals, and open communication, avoiding negative impacts like forced overtime. The ultimate goal is enhanced team productivity, not simply on-time delivery.

Why Software Estimation Is Always Wrong (and How to Improve)

2025-04-02

In Scrum teams, story points estimate effort, but software estimations are inherently flawed. They predict an unknown future, and project complexity, unclear requirements, and technical debt contribute to inaccuracies. Cognitive biases like Hofstadter's Law, Brook's Law, and the planning fallacy exacerbate the problem. The article explores improvements: tracking progress, adding buffers, using the COCOMO model, and an alternative from "NoEstimates": dropping story points, focusing on throughput and cycle times, and using visual tools like Kanban.

Multithreading: The Wrong Design?

2025-04-02

This article challenges the common misconception that multithreading always improves performance. The author argues that modern CPUs don't operate as a shared memory model as often taught, and multithreading introduces significant overhead due to cache coherence issues and synchronization primitives, leading to performance degradation and increased complexity. Duplicating single-threaded code across multiple cores is presented as a more efficient approach, leveraging CPU time more effectively and resulting in simpler, more maintainable code. The author advocates for single-threaded designs like Node.js and Actor models as superior for utilizing modern CPU resources, despite the perception that multithreading is a more sophisticated approach.

Graft: A Novel Edge Replication Engine for Strong Consistency and Partial Syncs

2025-04-02

Graft, an open-source transactional storage engine, tackles the challenges of data synchronization in edge computing environments. Unlike traditional full replication or schema-aware diffing, Graft employs a lazy, partial replication strategy that combines strong consistency guarantees, horizontal scalability, and object storage durability. It allows clients to sync data on demand, fetching only necessary data, and supports syncing from edge and offline devices. At its core is the Volume, a sparse, ordered collection of fixed-size Pages, with clients interacting through a transactional API. This makes Graft suitable for various use cases, including offline-first apps, cross-platform sync, and stateless multi-writer replicas.

The Linux Binary Compatibility Nightmare: Deconstructing and Rebuilding GLIBC

2025-04-01

This article delves into the deep-seated issue of binary compatibility on Linux, pinpointing the root cause as the monolithic design of GLIBC (GNU C Library). It critiques containerization solutions like Flatpak and AppImage for their shortcomings, proposing an alternative approach using static linking and older system libraries to improve portability. Ultimately, the authors advocate for a radical restructuring of GLIBC, breaking it into smaller, more focused libraries—libsyscall, libdl, libheap, libthread, and libc—to achieve Windows-like robust binary compatibility and finally solve this longstanding Linux problem.

Beyond Tech Debt: A Reflection on Organizational 'Debts'

2025-04-01

A LinkedIn post sparked a discussion not just about technical debt, but about various kinds of organizational 'debts,' including product debt, operational debt, process debt, and organizational debt. The author delves into the nature of 'debt,' arguing that it's not inherently bad; the key is whether it's incurred wisely. Sometimes, taking on short-term 'debt' to iterate quickly and seize opportunities is necessary, while over-focus on long-term planning can lead to missed chances. The article emphasizes that post-hoc analysis is easy, but the crucial element is clarity of decision-making at the time and foresight concerning future uncertainties.

AWS's Systems Correctness: A Multifaceted Approach

2025-04-01

Amazon Web Services (AWS) employs a robust system correctness strategy combining formal and semi-formal methods to deliver reliable services. Initially relying on TLA+ for modeling critical systems, AWS identified and eliminated subtle bugs early in development. The introduction of the P programming language, a more developer-friendly state machine language, further enhanced their approach, playing a crucial role in migrations like Amazon S3's move to strong consistency. Lightweight methods such as property-based testing, deterministic simulation, and fuzzing are also widely used. AWS further bolstered resilience with the launch of FIS (Fault Injection Service). For critical security boundaries, formal proofs, as seen in the development of Cedar and Firecracker, guarantee correctness. This multifaceted approach not only ensures reliability but also drives performance optimization and cost reduction.

Don't Let LLMs Make Decisions: They're Terrible At It

2025-04-01

The author, an NPC developer for an online game, argues against using Large Language Models (LLMs) for business logic and decision-making. Instead, LLMs should serve as a user interface, translating user requests into API calls and results back into natural language. LLMs are shown to be inferior in performance, debugging, and adjustment compared to specialized systems, using a chess-playing bot example. The author advocates for using LLMs for tasks like text transformation, categorization, and intent understanding, while relying on purpose-built systems for core logic. While LLMs will continue to improve, this architectural principle remains crucial.
