Looking at my parents’ silver hair and the lines the years have carved into their faces, my heart aches. After starting university, aside from a brief stint at home during military service, I’ve always been away — studying far from home, and now working even farther. Though I’ve never said it out loud, there’s a small knot of guilt that stays with me. I hope my parents live peacefully, healthily, and happily. That is my greatest wish for them. ...
Implementing Daemons in Embedded Linux systems is a fundamental task for long-running services. Based on the excellent Linux Daemon Writing HOWTO by Devin Watson, I have refactored several processes in my current project to run as background services (daemons). By backgrounding these processes, we ensure they remain resident in the system without blocking the console or being tied to a specific session. Core Implementation Pattern The following C snippet demonstrates the standard procedure for “daemonizing” a process: fork() from the parent, create a new session with setsid(), change the working directory, and close standard file descriptors. ...
Recently I was assigned to work on a streaming server. Working from the original development platform, we applied patches via shell scripts to transform source files — using patches on the original source code to generate modified files, then compiling those into the required libraries or executables. At first I didn’t think much about why this approach was used, but I’ve recently started to appreciate its advantages. The original source files we need are open-source packages downloadable from the internet. To track our modifications, we use the diff command to create patch files. When we combine multiple application components together, we end up with a collection of tarballs and patch files. We then manage them with shell scripts organized into three types: ...
Carey was a dog that my fiancée used to own. She passed away shortly after Dragon Boat Festival… The first time I met her, she bit me! In my entire life, I’ve been bitten by two dogs. The first was named Lucky — I forget if it was middle school or elementary school — but it wasn’t particularly lucky for me. I just wanted to pet her, and she bit me. With Carey, I also just wanted to pet her, and she bit me too… though not as badly as the first time. ...
Since high school, I used to buy computing magazines like PC DIY or gaming magazines — always chasing the latest trends: building a PC, playing games. Then, in my fourth year of university, a younger student was reading BusinessWeek, and I curiously asked why. He said he’d been reading it since high school, just out of interest, and that it offered many diverse perspectives. After that, I started buying a copy here and there — partly still following trends, I suppose. ...
I haven’t felt this way in a long time… I want to go home. Hide away at home… And be a willful, rebellious child again…
I happened to come across this article and wanted to share it with everyone. Source: http://www.drbataipei.org/wisdom/213/wisdom213_4.htm What is a person’s responsibility? It is to contribute and be of service to the entire world — to benefit all people everywhere. This is our true responsibility as human beings. Today we come together to discuss: “What does a person truly need?” and “Why do we come into this world? Is it merely to eat, dress, sleep, and enjoy ourselves?” ...

When I see that phrase, I think of the department backpack and T-shirt from university… “Wings”… Sometimes I wonder if I’m the odd one out — Not in a remarkable way, but in a quietly peculiar way… In my long search for certain answers about life, I’ve slowly drawn a few conclusions. The outline is still blurry, But a direction is taking shape. Since leaving the military, Coming to Taipei to work and to love, life is no longer as carefree as school days. On the surface, I seem composed, But beneath my behavior there’s a quiet uncertainty about the future — an unease I can’t quite name. ...
