Firefly Aerospace's Moon Shot: A Private Sector Gamble

Firefly Aerospace's Blue Ghost lunar lander is poised to attempt a moon landing, marking another milestone in the private sector's push for lunar exploration. The mission faces significant challenges; roughly half of all lunar landing attempts have failed. However, Firefly is confident in its in-house developed propulsion systems. A successful landing will see Blue Ghost conduct scientific experiments, capture stunning high-definition images, and potentially witness the lunar horizon glow – a phenomenon last observed by Apollo astronauts. This mission is a critical step in furthering lunar exploration and paving the way for NASA's Artemis program.

From SvelteKit to Plain HTML: A Website Rewrite

2025-01-15

Frustrated with the complexities of SvelteKit's build system, the author decided to rewrite their personal website using plain HTML and CSS. The process involved using Pandoc to convert Markdown to HTML and Python with uv for a lightweight build pipeline. Despite the small scale of the site, the rewrite resulted in a reduction in size from 356kb to 88kb and simpler, easier-to-understand code. The author notes remaining issues like code duplication and lack of live reloading, intending to address them in future improvements. The project serves as a simple template for building static sites with Markdown blogs.

Basketball's Data-Driven Revolution: From All-Arounders to Specialists

2025-02-15

Basketball is undergoing a data-driven revolution. Decision-making has shifted from intuition to precise data analysis, transforming the game from a reliance on points, assists, and rebounds to leveraging thousands of data points to optimize every aspect. The three-point shot reigns supreme, and the '3-and-D' player (three-point shooting and defense) is highly sought after. Technology, including motion capture and analytics systems, allows coaches to meticulously analyze player movement, maximizing possession efficiency. While this data-driven approach has made the game more predictable, it raises questions about the future of basketball.

Beyond Reproducible Builds: Towards Idempotent Rebuilds of Debian

2025-04-04

This article explores a new goal beyond reproducible builds for Debian packages: idempotent rebuilds. The author argues that simply reproducing published packages using older build dependencies (as done by the Reproduce.Debian.net project) is insufficient, as it relies on old binary packages that cannot be rebuilt from source. Therefore, the author proposes the concept of idempotent rebuilds, where iterative rebuilding eventually leads to a state where the rebuilt packages are identical to the previous iteration. This requires addressing issues like build timestamps and non-deterministic outputs. The author has completed stage 0 of the rebuild and plans to release the build artifacts for stage 1, with the ultimate goal of being able to bootstrap a Debian binary distribution from an environment like Guix. Challenges include the presence of non-free firmware and non-Debian signed binaries which might prevent self-rebuilding.

Dyson's Design: Tech-Obsessed or Marketing-Driven?

2025-07-07

This article offers a critical analysis of Dyson's design philosophy. The author argues that Dyson's excessive focus on technology results in shortcomings in ergonomics, usability, and reliability. Dyson products function more as status symbols than practical tools, leveraging the 'star designer' image and societal trends of tech worship. Using Dyson vacuums and hand dryers as examples, the author compares them to competitors, highlighting Dyson's lack of superiority in practicality and cost-effectiveness. The author concludes by urging designers to return to design's essence, focusing on user needs rather than blindly chasing technological showmanship.

Hydro: A High-Performance Distributed Programming Framework in Rust

Hydro is a high-level distributed programming framework for Rust, enabling the creation of scalable and correct-by-construction distributed services. Unlike traditional actor or RPC architectures, Hydro employs choreographic APIs and a high-performance single-threaded DFIR runtime. It simplifies deployment via Hydro Deploy, supporting both local and cloud environments. Using a two-stage compilation process, it generates deployment plans locally and then compiles to DFIR binaries for each machine, deploying them to the cloud based on the plan and cloud resource specifications. Hydro has been used to build various high-performance distributed systems, including implementations of classic protocols like two-phase commit and Paxos.

Is Zero Singular or Plural?

2025-01-22

A lively discussion on Stack Exchange explores the grammatical number of 'zero' in English. The question stems from a math textbook example using 'zero 3s', treating zero as plural. This isn't a mathematical rule but a quirk of English grammar. When 'zero' modifies a countable noun, the noun often takes a plural form, mirroring the usage of other words expressing negation. The debate highlights the complexities of English grammar and the sometimes counter-intuitive nature of language.

Serverless Computing: Why Haven't We All Switched Yet?

2025-01-09

Despite the appealing value proposition of serverless computing (e.g., AWS Lambda)—pay-per-use, auto-scaling, and abstraction from infrastructure—widespread adoption remains slow. The author points to two primary reasons: the lessons learned from the challenging microservices migration, where many organizations struggled due to insufficient technical and organizational readiness; and the fact that serverless amplifies existing challenges of microservices, such as complexities in dependency injection and observability. A gradual adoption approach focusing on highly autonomous teams and suitable use cases (like AI and LLM integrations) is suggested as a more efficient strategy.

GrapheneOS: Android's Unshakeable Fortress Against Forensic Attacks

GrapheneOS, an open-source, privacy-focused Android OS, recently faced a social media smear campaign falsely claiming it was compromised. The attack misrepresented consent-based data extraction as a security breach. This article clarifies digital forensics, Cellebrite's capabilities, and the distinction of consent-based data extraction. GrapheneOS's robust security features, including disabling USB connections in AFU mode, Titan M2's brute-force attack limitations, and auto-reboot, effectively counter such attacks. Cellebrite itself admits it cannot unlock fully updated GrapheneOS devices without user consent. The incident highlights GrapheneOS's superior protection of user privacy and data security.

Columbia Student Suspended for Leaking Disciplinary Hearing, Not AI Cheating Tool

Columbia University suspended a student for leaking a disciplinary hearing recording and photos of Columbia staff to social media, not for creating an AI tool that helps job candidates cheat on technical interviews. The student, Chungin "Roy" Lee, created Interview Coder, an AI tool that sells for $60 a month and projects $2 million in annual revenue. While Lee argued that technical interviews are outside the university's purview, Columbia deemed his actions academic dishonesty, resulting in a one-year suspension.

Beyond Two-Week Sprints: Exploring ShapeUp, Plan>Build>Ship, and GSD

Tired of the traditional two-week Scrum sprint? This article explores three alternatives: ShapeUp, Plan>Build>Ship, and GSD. ShapeUp emphasizes a six-week development cycle, starting with a thorough 'Shaping' phase, followed by a 'Betting table' decision-making process, and finally the 'Building' phase, avoiding the rush of short sprint cycles. Plan>Build>Ship is a simplified waterfall model where each feature is handled by a dedicated team from planning to delivery. GSD (Get Shit Done), popularized by Shopify, emphasizes efficient execution, using the internal tool Vault to track project progress, focusing on projects rather than tasks, and promoting team collaboration. These three methods each have unique characteristics, offering product teams more choices and helping them find the development process best suited to their circumstances.

Predictable Crowd Behavior: Insights from Pamplona's Running of the Bulls

A study published in Nature reveals that the collective movement of large crowds becomes predictable above a certain density. Researchers tracked approximately 5,000 people at Spain's San Fermín festival for four years, using cameras and a mathematical model. They found that at a density of 9 people per square meter, the crowd spontaneously oscillated like a fluid with an 18-second period. This predictable behavior, also observed in data from the 2010 Duisburg Love Parade tragedy, offers valuable insights for anticipating and mitigating dangerous crowd dynamics in confined spaces.
