Foxconn Navigates Tariff Troubles, Sees AI Server Boom

Foxconn CEO Young Liu revealed that US tariffs are causing significant headaches for tech giants like Apple and Amazon. In response, Foxconn's clients are increasingly planning US-based manufacturing collaborations to mitigate tariff impacts. While the consumer electronics business faces challenges, Foxconn's AI server segment is booming, with Q4 revenue up 78% year-on-year and projected to more than double this quarter. This growth is fueled by rising demand from smaller companies developing their own LLMs.

Orchid's Nutrient Theft from Fungi Illuminates Photosynthesis-Parasitism Continuum

2025-02-23
Orchid's Nutrient Theft from Fungi Illuminates Photosynthesis-Parasitism Continuum

Researchers at Kobe University discovered that the orchid Oreorchis patens, when near decaying wood, shifts its symbiotic relationship with fungi, absorbing more nutrients from wood-decomposing fungi while continuing photosynthesis. This behavior results in larger plants with more flowers. The study shows this 'theft' isn't compensating for insufficient photosynthesis, but boosting overall nutrient intake, providing an ecological explanation for why a photosynthetic plant might choose this parasitic path. However, less than 10% of these orchids exhibit this behavior, likely because suitable fungi are only found near decaying wood. This research enhances our understanding of orchids' balancing act between photosynthesis and complete parasitism.

Gorbachev's Reforms: A Helpless or Reckless Revolution?

Gorbachev's Reforms: A Helpless or Reckless Revolution?

This essay examines the reasons for the failure of Gorbachev's reforms, particularly the role of entrenched interests in the demise of the USSR. It compares two contrasting narratives: the "helpless" narrative, which argues that Gorbachev lacked power and was obstructed by powerful bureaucratic interests; and the "reckless" narrative, which contends that Gorbachev possessed significant power but pursued reckless reforms, especially the lack of crucial price reform, ultimately leading to the collapse of the USSR. By analyzing Gorbachev's power, personnel changes, and economic reforms, and by reinterpreting the coup against Khrushchev, the essay supports the "reckless" narrative, suggesting that Gorbachev's idealism and disregard for institutions were the primary causes of the USSR's collapse.

C's `defer` Keyword: A Blitz to Prevent Memory Leaks

A new feature is coming to C: `defer`. It acts as a general-purpose 'undo' mechanism, ensuring that a set of statements are executed regardless of how a code block exits, crucial for resource cleanup like freeing memory or unlocking mutexes. `defer` builds upon existing compiler extensions and similar features in other languages. The article details `defer`'s functionality, scope, and differences from similar constructs in Go, with examples illustrating its use. The author urges compiler vendors to implement `defer` promptly to enhance C code safety and maintainability, preventing memory leaks like those seen in CVE-2021-3744.

Code Reading: A Superpower for Bug Hunting

2025-09-08

This post details a significant career shift: from iterative coding to proactively finding bugs. Instead of relying solely on test-driven iteration, the author advocates for carefully reading code to preemptively identify problems. The key, the author argues, is to carefully read code, build a complete mental model of the program, and then identify the differences between that model and the actual code in Git. The post suggests focusing on control flow and data structures, and identifying potential error-prone patterns in the code. This approach dramatically reduces bugs and improves code quality.

OKRs: Tool or Trap?

This article explores the duality of OKRs (Objectives and Key Results). The author points out that many companies misuse OKRs for performance reviews, leading teams to overemphasize measurable metrics while neglecting the actual objectives and external effects. The author uses the example of Alexa to illustrate how blindly pursuing key results can be counterproductive. In contrast, Honeycomb uses OKRs as a tool for communication and reflection, treating key results as clues to observe the world and improve work, rather than ultimate judgment criteria, thus avoiding metric distortion.

This article tackles a mathematical puzzle involving an infinite grid of numbers arranged in a spiral pattern that reverses direction at each grid edge. By analyzing patterns along the spiral's edges and diagonal, the author derives a closed-form expression, (f(m, n) = (max(m, n))^2 - max(m, n) + 1 + (-1)^{max(m, n)} (m - n)), to calculate the number at any position (m, n) in the grid. The article meticulously details the derivation, including analysis of edge and diagonal numbers, and the process of transforming a piecewise function into a single closed-form expression.

Kernel panic traces are notoriously difficult to copy and paste into bug reports, hindering debugging. The `panic_report` project solves this by embedding a QR code generator written in Rust directly into the Linux kernel. This allows users to easily scan and share the encoded panic information. The project, which prioritizes memory safety thanks to Rust, has been merged into Linux kernel v6.12-rc1 and is soon to be enabled in Arch Linux. A web frontend simplifies decoding the QR code.

Isomorphic Web Components: Server-Side Rendering Made Easy

The long-held belief that server-side rendering of web components is difficult has been challenged. This article demonstrates how to achieve server-side rendering of existing web components by cleverly using Happy DOM to emulate a browser environment. Two methods are detailed: using the `` tag for direct rendering and emulating the DOM to run component code and generate HTML. The author emphasizes the advantages of this approach: compatibility with all web components, robustness in the face of JavaScript failure, and avoidance of framework lock-in. This solves the server-side rendering problem for web components, offering a flexible and resilient solution.

A 1Hz Clock from Three Candles: Reversing Millennia of Optimization

For millennia, candlemakers have strived for flicker-free candles. However, when three candles are bundled together, they surprisingly begin to oscillate naturally at ~9.9Hz, a frequency primarily determined by gravity and flame diameter. The author ingeniously uses a wire suspended in the flame to sense capacitance changes caused by ionized gases, detecting this frequency and dividing it down to 1Hz. The result? A 1Hz clock built with a simple microcontroller and an LED, powered by the flickering of three candles.

Over a decade and three companies, the author observed a recurring pattern: Redis was frequently overused. Even at Tantan, a high-performance database system, Redis, initially intended to cache a small amount of user interaction count data, proved unnecessary. It could be efficiently stored directly in PostgreSQL without added complexity. Similar unnecessary Redis implementations were found in two other companies, adding complexity to low-load systems without significant performance gains. The author advocates for careful evaluation of new technologies, avoiding 'tech for tech's sake', and opting for simpler, reliable alternatives.
