Alibaba Large Model Strategy

Alibaba (Ali) has released numerous large models, not simply a matter of “volume chasing,” but a carefully planned “Model-as-a-Service” (MaaS) ecosystem strategy. There are multiple considerations behind this, which can be summarized as “internal empowerment and external ecosystem building.” Internal Business Driven (Inward Empowerment) Alibaba possesses an extremely vast and diverse business landscape, including e-commerce (Taobao & Tmall), finance (Ant Financial), logistics (Cainiao), cloud computing (Aliyun), and entertainment (Youku), among others.

Hang Seng Index Crash, Meituan Considering Exit? Examining Xiaomi, Alibaba, and Meituan’s New Valuation Anchors Through “Ecological Premium”

Recently, Xiaomi’s third-quarter financial report was released, with little expectation beyond the usual. The US situation is unsettled, Hong Kong stocks have recently experienced liquidity stagnation, and the Hang Seng Technology Index has retreated significantly. As a major participant in the food delivery war, Alibaba, which bears the highest e-commerce taxes, hasn’t generated much discussion online. I don’t remember if I wrote any previous articles, when I bought Xiaomi, I didn’t really think about what supported Xiaomi’s market capitalization at that time – perhaps after watching too many TikTok-related videos?

Claude Code Frequently Asked Operations Guide

Here’s the English translation of the provided text: “cc provides so many commands, which ones are actually useful? I’m going to watch some video tutorials on Douyin and simply record what I find helpful. The generated normalized git logs automatically include copyright information, but since we’re now using domestic large models, there’s no need to add the copyright (GitHub displays cc as a collaborating developer). Find the user configuration file and add the setting "includeCoAuthoredBy": false.

Local Development Pain: Why Can't You Delete `nul` Files? A Solution to the “Composite” File System Problem

In the daily work of software development, we often encounter tricky “minor issues” that seem simple but can consume us hours of valuable time. One such “disaster zone” is deleting specific files – particularly those generated unexpectedly by toolchains. I encountered a “level-boss” problem: during local development, a file named nul inexplicably appeared in my project. I tried Windows Explorer, the CMD command line, but the system displayed “File not found” or “Cannot delete.

Command-line AI Coding Interaction

The convention is to open Trae and prepare to start coding, and a notification arrives: the Claude model has been shut down and cannot be used; it’s highly likely that it won’t be recovered. The official provided a compensation plan, increasing usage by 300 (as of January). Checking it out, as expected, Anthropic is following US regulations to prohibit domestic companies from continuing to use the Claude series models. I joined the trae Discord community and saw many people complaining about the shutdown of the Claude model – after all, most people came here for Claude.

Big Tech Dominance in the U.S. Stock Market Intensifies: The Top 10 Companies Account for 40% of Market Capitalization, Is AI a Bubble or a Revolution?

Analysis of NVIDIA’s “Play” Worth a Billion Investment The global capital market is witnessing an unprecedented wave of centralization in 2025, centered around artificial intelligence (AI). This narrative not only reshapes the tech industry’s landscape but also exacerbates wealth inequality on Wall Street.

LPL’s Korean Invaders and the “All Chinese Squad” Dream: A Game About Results, Development, and Belonging

Data Mining

Deep Learning

Neural Network

It’s undeniable that the surge of big data, coupled with recent news about competitive matches, always prompts me to take a look. Similar videos on TikTok have been proactively dismissed – I don’t want to keep receiving homogenous content. I also forgot about an account; unsurprisingly, TES lost decisively, and related topics were trending on Zhihu’s hot list. A highly-voted answer mentioned LPL’s Korean reinforcements and the concept of “all Chinese team.”

Without that year’s IG victory, League of Legends is likely already over. ldl’s strategic play, combined with multiple debuffs, contributed to LPL’s performance as a region.
