A paper presented at the 2025 ACM Symposium on Operating Systems (SOSP) outlines how Alibaba Cloud's Aegaeon pooling system employs token-level scheduling to optimize GPU utilization for large language models (LLMs). This innovation reduced the need for Nvidia GPUs from 1,192 to just 213 during beta testing, enhancing inference capacity significantly, particularly in constrained markets like China. Aegaeon allows multiple models to share a single GPU by virtualizing access at the token level, resulting in

The content discusses feedback received regarding a Mac OS X utility designed to visualize QuickDraw (PICT) files and export them to PDF format. The author developed this program to learn Swift programming by rewriting an old Java QuickDraw code they had created. Although functional, the program has some rendering issues and a rough user interface, and it was released to commemorate the 40th anniversary of the Macintosh. The utility is not a pixel-perfect QuickDraw renderer; instead, it simulates how images would appear on

The article discusses the disparity between the general hype surrounding AI in mainstream media and the more grounded perspectives of professionals within the tech industry. While AI is a major topic in tech, many engineers and product managers believe it should be viewed as a "normal technology" rather than a transformative entity. They express frustration at the sensationalism surrounding AI, which often leads to unrealistic expectations and a cult-like reverence for the technology. Instead of focusing on an informed discussion from within the industry, media often amplifies voices

The author has struggled to understand the memory layout of C++ objects, prompting them to conduct experiments to clarify the concept. The experiments are based on the Itanium C++ ABI, used by GCC and Clang, which governs aspects not defined by the C++ standard, such as vtable layout, vptr location, virtual function dispatch, and RTTI. The post aims to provide insights into these memory layouts, particularly for single inheritance, using diagrams and practical examples. Each polymorphic object, defined
