Excel常用函数入门:公式、区域、绝对引用和错误值

Introduction to Common Excel Functions: Formulas, Ranges, Absolute References, and Error Values

Have you ever had this experience: you open a spreadsheet, see an equals sign in a cell, and think, “This is just a simple calculation,” but as soon as you hit Enter, Excel throws an error value at you, and you’re instantly stumped? Don’t worry—Excel isn’t trying to trip you up. It’s actually trying to communicate with you, but it’s using terms you haven’t quite grasped yet.

8 个能找到 Agent Skills 的平台,顺便聊聊怎么挑

8 Platforms Where You Can Find Agent Skills—Plus Some Tips on How to Choose

When I first started using the AI Agent, I really thought of it as an all-around worker. But after using it for a while, I realized that while it can understand requests, write, and chat, it doesn’t magically develop new skills on its own. Later, I added skills to the agent one by one, and my efficiency shot up immediately. Some tasks that used to require switching between several tools to complete can now be handled by a single agent. It was also around that time that I started paying close attention to the agent.

I’ve been tinkering with installing skills for my AI agent lately, and there’s one thing that’s been giving me a real headache. The skill descriptions on English-language platforms are just too difficult to read. So I thought, why not try a few Chinese platforms instead? It took me about two weeks in total. I basically tried every Chinese AI agent skills platform I could find, and in the end, I narrowed it down to five that I think are worth talking about. 1. SkillHub Website: htt

AeroCore Theme SEO Optimization: Prevent indexing of date and search pages; add page numbers to pagination titles

My website uses the AeroCore theme. I’ve encountered two issues: the date archive page and the site search page have been indexed by Google, but these pages are of no use to users; the pagination titles on the category, tag, and author pages are exactly the same, so Google may consider these pages to be duplicate content. To resolve these issues, I added a few lines of PHP code to the functions.php file in my child theme. This code consists of two parts:

AeroCore Theme LCP Optimization: Images, JS, CSS, and Preconnect

My website uses the AeroCore theme, and I noticed that there are many images on the post and list pages—all of which use lazy loading, including the above-the-fold section. However, using lazy loading for the above-the-fold section affects the LCP score. I’m also using a few third-party scripts and stylesheets, which have caused the above-the-fold section to load very slowly. My LCP score isn’t very high either. So I wrote a piece of PHP code. This code consists of four parts. The first part sets the images to “eager” and
