wrk vs. JMeter deep benchmarking
In internet system stress testing, we frequently encounter two tools with vastly different styles: one is extremely lightweight, pursuing extreme throughput—wrk; the other is feature-rich and simulates real business flows—JMeter. Prompt: Outline the core ideas and write a科普 article (explanatory article): HTTP
Detailed Explanation of How Passkeys Work and Their Future
Background introduction: Tencent’s CNB platform only supports WeChat login, with no conventional email account method, leading to several guys in the group complaining about it daily – it’s getting annoying. The Tencent product manager came up with a compromise solution: support Passkey login.
Every day, we are repeating a dangerous action: entering passwords. Despite our complex rules (uppercase, special symbols, numbers), data breaches, phishing attacks, and the frustration of “forgotten password” issues continue to trouble everyone.
Tech giants (Apple, Google, Microsoft) along with the FIDO Alliance have provided the ultimate solution: Passkey (Passcode Key). It’s not just a “replacement” for passwords; it completely “eliminates” them.
The login process has shifted from verifying passwords to verifying the current device’s trustworthiness.
Is AI Getting “Dumber”? Uncovering the Game Between Parameter Accuracy and Inference Costs
Recently mingling in various programming large model communication circles, the most complained about thing is model degradation.
- Models deployed on local desktop computers are quantized models, essentially downgraded versions.
- With “vibe coding” so popular, could it be that the content output by current large models is the most valuable product – code?
Analyze the defaults and delinquencies in Chinese real estate.
Real estate giants’ top performers – Ever, also failed to hold up, continuous blood transfusions for Sunshine Steel, ultimately couldn’t plug the ever-growing hole. Linkage news: Six major banks completely halt sales of 5-year large savings bonds for five years.
Analyze China’s real estate defaults, compile timelines and key events, Evergrande, Greentown, Vanke, and other unlisted property developers I may not know about.
This overview is based on the latest perspective as of December 2025, covering the complete timeline from the initial crisis to the current period (end of 2025).
Gemini CLI installation and deployment, Google is catching up.
It’s been almost half a month, and MiniMax and GLM4.6 in China have both had paid trials – the difference is still noticeable. The cc tool is quite useful. Last night I was messing around with optimizing the front-end interface, you know… as a writer, I basically don’t understand front-end development; Vibe Coding will be next, and I’m starting to get into the front-end technology stack. Domestic large models haven’t been figured out; I tried the newly released Gemini3, and it was done in five minutes.
Cloudflare experienced a global network outage, causing websites like X (formerly Twitter) and ChatGPT to crash. The stock price suffered a setback ahead of the market open.
This site’s main domain is hosted on GitHub Pages, and the blog’s backup subdomain is on Vercel with acceleration. It has been deployed through Cloudflare. The backend management page looks too outdated and unappealing, which is a major deterrent. Initially, it was a quiet, unassuming piece of content; however, constant messages in the blogging circles disrupted this tranquility – opening it up, CF went down, and many friends’ websites couldn’t be accessed.
As an internet infrastructure component, such prolonged downtime is unacceptable. The stock price didn’t plummet dramatically, which I hadn’t anticipated.
Understanding MySQL Gaps Locks: From Principles to Enterprise-Grade Selection
System data synchronization between systems, recently when changes occurred, the data volume of a certain interface increased, frequent deadlocks happened. After colleagues investigated, they found that it was caused by gap locks. MySQL is not used much, so I’ll record it down.
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.
