This article delves into how to leverage Zero-Width Joiner (ZWJ) technology to create custom yellow handshake emojis. The author provides a detailed breakdown of Unicode code point structure, demonstrating how to decompose and recombine emojis using JavaScript to bypass Apple's restrictions on emoji combinations. The piece explains the relationship between skin tone modifiers and the Fitzpatrick scale, and shows how to create custom emoji combinations that can't be directly generated through Apple's keyboard. While these custom emojis can't be displayed as large single messages on iOS/macOS, this technique offers developers a new perspective for exploring the boundaries of character encoding. For tech enthusiasts interested in character encoding, emoji implementation, and overcoming system limitations, this article provides valuable knowledge and technical examples.

NVIDIA has officially launched the Nemotron 3 series models, the most efficient family of open-source models to date, specifically designed for agentic AI applications. The series includes three models: Nano, Super, and Ultra, each excelling in cost efficiency, collaborative agents, and high-precision inference respectively. Nemotron 3 utilizes innovative technologies, including a hybrid Mamba-Transformer MoE architecture, latent expert design, and multi-token prediction, supporting context lengths up to 1 million tokens. The Nano model achieves inference efficiency 3.3 times greater than comparable models while maintaining high accuracy. NVIDIA has open-sourced the Nano model's weights, training recipes, and related data, providing valuable resources to the AI community. This launch marks a significant breakthrough for NVIDIA in the field of efficient AI models and will have a profound impact on AI application development and deployment.
