Persistent Efforts Eventually Bear Fruit

An “Adventure” Journey with Equipment Upgrade The Trigger: Old Equipment Struggling The company’s contact angle measurement device can be described as having “veteran-level” configuration - this computer came with the instrument back in the day. It’s a long story of hardship: not only is the configuration inherently insufficient, but years of accumulation have made it increasingly difficult to use. The most frustrating part is those USB 2.0 ports, with transfer speeds so slow they make you want to stomp your feet. ...

Microsoft Copilot Experience

Background I’m someone who really likes various AI tools, especially various AI assistant tools, such as: Microsoft Copilot, Claude, Gemini, LLama, and domestic ones like: Tongyi Qianwen, Kimi, etc. I’ve used quite a few. For Microsoft Copilot, I’m really looking forward to it, especially its deep integration with Microsoft 365 (Office suite), which is really practical. As an individual user, this service is mainly targeted at enterprise customers, and the pricing is quite high, so I haven’t had a chance to experience it. The key point is that in the company environment, I use Microsoft 365 suite heavily every day, processing various documents, emails, meetings, writing documents, making PPTs, processing Excel, etc. If I could use Copilot, it should greatly improve work efficiency. ...

Returning to Reading

It’s Been a Long Time Since I Read Properly Ever since I failed the WeChat Reading 365-day challenge last time, I haven’t opened WeChat Reading again. That’s not entirely true, but I really haven’t read a complete book since then. Even my favorite novels have been left untouched. Change The truth is, I really do love reading, and I think WeChat Reading is genuinely one of the best apps out there. Among all Tencent’s applications, it’s truly a conscientious productno ads, no messy recommendations. I really like it. ...

Mac Mini M2 to the Cloud

Reason Because the company has rules and regulations, information security protection, and data compliance protection. As R&D personnel, our HBI computers are monitored very strictly by the company. Then I think it’s also good to do some data isolation, protecting the company’s privacy. I also hope that my personal data is not on the company’s computer. If something happens, all my data is lost, which is not worth it. I can easily access it at home through the local area network, basically without any delay. Accessing through my Chrome OS is perfect. At the company, I can also access it conveniently. The latency is acceptable and reaches a usable state. At least it can ensure that I can access the content I want anytime, anywhere. ...

Restarting the Blog

Introduction I think as someone who organizes their life and expresses their emotions, I need a place to record my thoughts and reflections, so I’ve decided to restart using this blog to document my life. It’s been almost a year since I last used it. There were many reasons I couldn’t persist, some controllable, some not. Starting Over I’ve decided to restart using this blog to share some of my learning process, hoping that people I know and don’t know can gain something from it. Before, I didn’t understand many things, and building a website required searching for a lot of information. A year later, with the addition of numerous AI tools, I can record what I’ve learned and thought much faster. I’m full of motivation to take action. ...

Using Google Sheets to Automatically Create Google Calendar Events for Dynamic Project Management

Background Since I couldn’t find a suitable tool for project management with my specific requirements, I decided to build my own using Google Sheets, Google Calendar, and Google Apps Script. Actually, I didn’t write it myself - I had ChatGPT help me write it. The main function of this tool is to display very small project units precisely on my calendar. I have many samples that need to be tracked for stability over time, so I need a tool that can accurately record these sample time points and remind me. At the same time, this tool also needs to be displayed on Outlook, so I can see the project progress while working. ...
