Tour de France: Has Technology Conquered Doping?

The Tour de France was once plagued by doping scandals, with Lance Armstrong's 'extraterrestrial' performances revealed to be fueled by banned substances. However, the modern Tour presents a different picture: advancements in technology and scientific training have enabled unprecedented levels of performance. The exceptional achievements of riders like Tadej Pogačar are attributed not to doping, but to power meters, data analysis, precise nutrition plans, and aerodynamic improvements. This marks a new era for cycling, where technological progress has triumphed over the lure of performance-enhancing drugs, pushing the boundaries of human physical capability.

The AI Cheating Crisis: A Professor's Lament

The proliferation of AI tools like ChatGPT has led to a surge in student cheating. A California philosophy professor recounts the devastating impact on his teaching, as students use AI to generate essays, circumventing the learning process. While he explores various countermeasures, all prove limited. He argues that education transcends job training; it cultivates critical thinking and life understanding. AI cheating deprives students of this invaluable experience, ultimately harming both the students themselves and the fairness of the education system.

Efficient Backpropagation: Simplifying Linear Transformation Derivatives with Einsum

2025-09-14

This post presents a clever backpropagation trick that simplifies the derivation of any einsum expression through a simple letter swap. Einsum is a concise way to express linear transformations such as matrix multiplication, dot products, Hadamard products, and more. The article uses matrix multiplication as an example, showing how to perform forward and backward propagation using einsum and verifying the results with JAX. This method avoids complex derivations, significantly simplifying backpropagation calculations in deep learning.

Microtriangles: The Real Killer of Rendering Performance, Not Poly Count

2025-07-19

Microtriangles: The Real Killer of Rendering Performance, Not Poly Count

The old lore about polygon count determining rendering performance is outdated. Modern rendering is significantly impacted by microtriangles. This article argues that tiny triangles (under 10x10 pixels) become exponentially more expensive to render because GPUs compute a full 2x2 pixel block even if the triangle only covers one pixel. The author suggests focusing on "wireframe view density", switching to lower LODs when the view gets close to solid, or using a single LOD with imposters for distant objects. Epic's Nanite technology tackles this by using compute shaders and screen-space shaders to minimize the cost of rendering microtriangles.

A Programmer's Rejection of AI Coding Tools: Efficiency, Ethics, and Environment

2025-06-18

A seasoned programmer explains their refusal to use AI coding tools, not out of technological resistance, but from deep concerns about efficiency, ethics, and the environment. The author argues that the productivity gains of current AI tools are questionable and that they risk introducing more errors. Additionally, AI model training puts immense pressure on the environment, and its data sources raise ethical concerns, including intellectual property infringement. The author emphasizes the joy of "struggle and learning" in programming and the advantages of manually written code in terms of quality and maintainability. Ultimately, they choose to stick with traditional programming methods and call for stronger regulation of AI technology.

Microsoft Starts the New Year with More Layoffs

Microsoft has begun the new year with another round of layoffs, affecting less than 1 percent of its workforce. The company claims the cuts are performance-based, aiming to improve overall team efficiency. While Microsoft laid off over 10,000 employees in 2023 and more in 2024, these latest cuts come despite record earnings. The layoffs may be linked to Microsoft's aggressive push into AI, with some suggesting that the eliminated positions will be quickly refilled with AI-related roles. This suggests a significant shift in Microsoft's strategic direction.

Dissecting ScatterBrain: A Deep Dive into Shadowpad's Sophisticated Obfuscator

POISONPLUG.SHADOW (Shadowpad), a malware family first identified by Kaspersky, utilizes a custom obfuscating compiler, ScatterBrain, to evade detection. Google's Threat Intelligence Group (GTIG) and the FLARE team collaborated to reverse-engineer ScatterBrain, creating a standalone static deobfuscator. This deobfuscator tackles ScatterBrain's three protection modes (Selective, Complete, Complete "headerless"), neutralizing its control flow graph obfuscation, instruction mutations, and import table protection. This research significantly enhances the ability to analyze and counter sophisticated malware like Shadowpad.

Shorty: A More Concise C++ Lambda Library

Shorty is a C++ library designed to offer a terser syntax than native C++ lambdas, not to replace C++ with a lazy DSL. It allows for more intuitive notation for sorting, filtering, zipping, and calling external functions, supporting various argument access methods and type conversions. For example, `std::ranges::sort(subject, $lhs > $rhs);` sorts concisely, and `subject | std::views::filter(($i % 2) == 0);` filters even numbers. Its design prioritizes developer efficiency and reduced boilerplate code.

Subtle C++/WinRT Invoke Issue and its Fix

Subtle C++/WinRT Invoke Issue and its Fix

A C++/WinRT pull request fixed an ambiguity in `winrt::impl::promise_base::set_completed`'s call to `invoke`, caused by Argument-dependent Lookup (ADL). The upgrade to C++20 coroutines expanded the ADL search space, unexpectedly finding `std::invoke` instead of the intended `winrt::impl::invoke`. The article details the ADL mechanism and provides a patch for older C++/WinRT versions: declaring a better-matching `invoke` function in the `winrt::Windows::Foundation` namespace to guide the compiler. This patch also includes a static assertion to ensure it's automatically removed after upgrading C++/WinRT.

Puerto Rico's Microgrids: Grassroots Innovation Against Power Crises

Facing frequent blackouts due to its aging grid, some areas of Puerto Rico are relying on microgrids and solar power systems to maintain electricity supply. During an island-wide blackout in April, Adjuntas town's microgrid system successfully kept the lights on for many residents and businesses. However, $20 billion in federal disaster relief funds have been hampered by bureaucratic red tape and politics. Despite this, private efforts are pushing the development of solar and energy storage systems, with 4,000 systems coming online each month, showcasing resilient grassroots innovation. Adjuntas' example, with its strategy of interconnected microgrids, successfully withstood the blackout, offering valuable experience for other regions.

Memory-Efficient C Structs: A Deep Dive

2025-07-31

This blog post explores techniques for optimizing C structs to minimize memory usage. Using a `Monster` struct as an example, the author demonstrates several optimization strategies. These include reordering members to reduce padding, removing redundant fields (e.g., inferring `is_alive` from `health`), using smaller integer types (like `uint8_t`, `uint16_t`), employing bitfields for booleans, and replacing strings with enums for monster names. These optimizations shrink the `Monster` struct from 96 bytes to a mere 20 bytes, significantly improving memory efficiency. The post also discusses trade-offs and potential issues like integer overflows.
