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. ...

I’ve started collecting the information around the end of 2010 because the wireless technology advanced to much higher bandwidth for multimedia streaming. There are two conditions of the development that I thought. 1. To develop the whole wireless part by ourselves. 2. To buy the module directly from the supplier. But some important factors that make me just ‘collect information’ at that moment. For 1, the expense is very horrible. - We have to pay chip vendor for NRE. - We are new to be the player and we have no credit to the chip vendor. - We have no equipment and we have to invest a lot to do it. - There are lots of tasks need for the regulation. To sum up, this is a money game for surveillance company and we see no market at that moment. For 2, we could leverage a lot tasks to supplier but we still have to prepare equipment to verify the whole system and get the experience of the regulation. However, the module cost and performance ratio could not meet our requirement. It is quite challenge for me to persuade my boss to do it. So what I can do is just keep attention on wireless technology. Until now, I have the chance to do the development finally. Although I’m newbie for wireless, it’s not too hard to enter this area. The reason is the technology become much mature and we can make it work even we do not know much about wireless. So, let’s just do it. The module I use is based on Atheros AR6103 and AR6003. The driver of these two chips are similar. The documents I study is are mainly from Atheros. I also reference the IEEE specification and search on Google. ...

I found an interesting comic that made by Gavin Aung Than. The philosophy is suitable for every creative work. http://zenpencils.com/comic/90-ira-glass-advice-for-beginners/

There is a very hot TV program which name is “I’m a singer” in China. I never saw this program before because there are already lots of similar program in the world. At the first, I could not understand why this program catch so many eye balls. My memory was stay at the program that is made by Taiwan’s media years ago. Even it’s hot at season one, it become colder and colder till now. At least, I do not have that passion to see this kind of show again. So it cause my curiosity why it success at this moment in China. After searching the information on the internet and spent hours to see the last episode of season one last weekend, I start to know why it become so famous. ...
