Microsoft's AI Chief Plots a Future Without OpenAI

2025-03-07

Microsoft's AI head, Mustafa Suleyman, is leading a push to reduce the company's reliance on OpenAI. Despite over $13 billion in investment, Microsoft seeks greater control and cost reduction. This involves transitioning away from OpenAI's models, a complex undertaking given their deep integration into products like Copilot and Bing. Microsoft is testing alternatives and gradually replacing OpenAI models with in-house options like Phi-4, but faces significant challenges due to contractual obligations and technical dependencies. Success would grant Microsoft greater cost control and market competitiveness.

Derivatives, Gradients, Jacobians, and Hessians: A Deep Dive

This article provides a clear explanation of derivatives, gradients, Jacobian matrices, and Hessian matrices, four fundamental concepts in calculus and their applications. Derivatives describe the rate of change of a function, gradients point in the direction of the greatest increase, Jacobian matrices describe the warping of space for multivariable functions, and Hessian matrices contain second-order derivatives, describing curvature. These concepts are crucial in optimization algorithms (like gradient descent) and computer graphics (e.g., anti-aliasing rendering), providing a deeper understanding of machine learning and graphics rendering.

High-Performance Dynamic Dispatch with GLIBC hwcaps

2025-07-16

This article demonstrates how to leverage GLIBC 2.33+ hwcaps for simple dynamic dispatch in amd64 and POWER shared libraries. By creating library files for different CPU instruction sets (e.g., x86-64-v4, x86-64-v3, etc.) under `/usr/lib/glibc-hwcaps/`, the dynamic linker automatically loads the corresponding library based on the highest instruction set supported by the CPU, optimizing performance. This solves the challenge of maintaining consistent library performance across different CPU architectures, as demonstrated in the Debian packaging of the ggml library used by llama.cpp and whisper.cpp.

NOAA Shuts Down Billion-Dollar Weather Disaster Database

NOAA Shuts Down Billion-Dollar Weather Disaster Database

The National Oceanic and Atmospheric Administration (NOAA) announced it's retiring its well-known "billion-dollar weather and climate disasters" database, making it harder to track the cost of extreme weather events. This database, active since 1980, tracked the financial toll of disasters from hurricanes to hailstorms. Its discontinuation is seen as another blow to public access to information about how fossil fuel pollution is exacerbating extreme weather. While population growth and development contribute, climate change intensifies these events, increasing costs. The move follows staff reductions at NOAA leading to service cuts, and further budget cuts are proposed, jeopardizing future data collection and accessibility.

Why VCDs Kinged Southeast Asia: It Wasn't Just the Mold

This article explores why VCDs and Laserdiscs were more popular than VHS tapes in humid Southeast Asia. While mold damage to VHS tapes was a factor, economics played a far larger role. VCDs were cheaper, smaller, easily duplicated and distributed, making them the dominant format, especially in the rampant piracy scene. Laserdiscs, while offering better quality, were too expensive for most consumers. The author recounts personal experiences in Singapore, illustrating the VCD market's dominance and its competition with VHS.
