on: RIP Hao Chen, the Chinese blogger
R.I.P
He is really a wonderful person. His blog CoolShell helped countless people starting the career in programming. It's been a long journey for me through my undergrad and now PhD student in CS, but I still remember the time that learnt quite a lot from his blog. It's still stared on my homepage all the time. I'll carry on his passion about explaining many complicate concepts in software engineering.

on: Ask HN: How to track flying objects?
I've been working with motion capture system for several years as a phd student in robotics. The first thing came into my mind is the motion capture system which is already mentioned by someone ahead. I worked in one of the largest indoor motion capture in academy, the ASU drone studio which possibly can be a reference if you searched it. But the cost of such a field is pretty high since you basically have to cover every corner with camera each of which costs 4k-6k dollars. It can track 10s of objects easily with sub-mm accuracy and 360 frame per second.
