It Started with a Complaint Day three. This little dev board is seriously tough. Claude Code’s free-tier generosity let me sprint hard, but I still hit the usage limit. I went to a conference that morning, and the whole time one thought kept looping in my head: How much time have I spent copy-pasting? JTAG call stack, SWD register dumps, Serial Console logs — paste a chunk over, AI gives a suggestion, I tweak the code, rebuild, flash, grab the logs, paste them back. Over and over. Sometimes I paste into the wrong window. Sometimes I miss the critical three lines. ...

Introduction In our pursuit of the “All in AI” philosophy, the process of internalizing and producing knowledge shouldn’t be hindered by complex toolchains. By deeply integrating Obsidian with the chenfu.ai project, I have successfully achieved a seamless “edit-to-publish” experience. By incorporating AI-assisted analysis, every note I take now resonates with my historical technical expertise. Phase 1: Basic Connection and Path Optimization First, we set up Obsidian as the dedicated editor for the Hugo project, linking local files directly to the Vault. ...

No more words to say. Farewell my little angel…

Weeks ago, my colleague saw a very interesting video on Ted. He sent me the link and I’m really excited. The reason why he sent me was because we ever discussed the future of the video system month ago. Everyone raised different ideas of the device and my idea is the quadcopters with camera on it. Why I wanna do such kind of device is oriented from my study in university. I’ve been studied the mechanics in Aeronautics and Astronautics department, bachelor plus master are total 6 years. There is less such kind of career opportunity in Taiwan because of the environment. Lots of my classmates join the semiconductor industry to be equipment engineers in the company like TSMC, CMO…etc. A little part including me choose different road to be R&D engineer in other industry. ...

Recently, I’ve become very busy due to taking over tasks from another site. The original coding work is still there, so I started looking for an outstanding developer to join us. In the first month, I tried to draw from my colleagues’ and my own networks — but in vain. Now I’ve shifted the search to a headhunter and started conducting interviews. I’ve interviewed a lot of people at my first and second jobs. Interviewing candidates through a headhunter is a very different experience. Why? Many factors influence what kind of developer you’re actually looking for. ...

Recently, my workload has surged significantly as I’ve taken over tasks from other sites. Between managing original coding responsibilities and new oversight, I’ve started a serious search for outstanding talent to join the team. During the first month, I tried sourcing candidates through internal referrals and my personal network, but without luck. I’ve now moved this search to headhunters and have begun the interview process. I interviewed many people in my first two roles, but interviewing candidates recommended by headhunters at this stage of my career feels different and much more interesting. The criteria for what kind of developer you need are heavily influenced by the organization’s current goals and history. ...

The PoC is power over cable and it’s just like the PoE on IP camera. I met a supplier that they can provide the PoC solution on the ccHDtv system. Originally, I thought it’s a useful and necessary function but it’s not at all now. Why? The CCTV is always starting from system point of view but not just the device only like the cellphone. The first factor is that the analog CCTV infrastructure has already built over there for a long time. That means the power cable is existing and reliable. So it is not necessary to equip the PoC except the project a brand new installation. The second, the strategy of the ccHDtv alliance is to replace the traditional analog surveillance system from VGA to HD but not to compete with the existing IP surveillance system. We can totally confirm that it’s not necessary to equip PoC on DTV camera. The others factor like the cost increase, design complexity increase and regulation to pass. ...

What is ccHDtv? Closed Circuit HD TV (ccHDtv) is a newly developed solution for transmitting full HD digital video in a surveillance system. The core concept of ccHDtv is to deliver high-definition video using digital TV (DTV) transmission. With ccHDtv, high-definition digital video can be transmitted easily over coaxial cables, twisted pairs, or simply over the air. Multiple 1080p30 and 1080p60 video streams can be easily transmitted using ccHDtv over a single 3C2V/RG59 cable up to 500 meters without any repeater. ...
