Everyone knows that MIT has an open course project. One of them is “16.885J / ESD.35J Aircraft Systems Engineering“. I am interested in this one because it was given by top scientists, engineers and managers in the field of space shuttle design, development and operations. Therefore, it offers first hand experiences and information in terms of system engineering of space vehicles.
I personally listened through all the video lectures of this course. One thing I have to say is that it is not a systems engineering course in general. Rather, it is an “Aircraft Systems Engineering” as the title says. So, it is an excellent reference if you are taking a class in an aircraft systems engineering somewhere else, or you are in this field and want to gain more knowledge and second hand experiences, or you want to know the history of space shuttle. I learned a lot from the course. Unfortunately, most of the slides used in classroom are not available on the internet. Sometimes, you would have to guess on speakers. Please note that there are transcripts available and it is particularly useful.
While I was listening this course, I put together a list of lectures.

LUNAR organizes model rocket launch at Moffett Field every month, and the one on July 19, 2009) was definitely the biggest one. Sure it is a huge success, but there was a little problem: Many people do not follow the rules there since they are first time visitors. For example, I saw some people tried to catch rockets and took away. They thought whoever grabbed the rockets could own them. No, it is not true. The model rockets belong to those who build them. When I launch my rocket, it is MY rocket.

I saw this curve the other day and thought it was cool. Programmers do have productivity period every day and this curve does reflect the trend, at least I think so. A lot of start-up companies let their programmers work a lot longer than 8 hours. Their bosses offered free diner so that employees will stay longer. On one hand, I understand they have a lot to achieve in a short period of time, but on the other hand, I wonder whether it is really working. Isn’t there a better way?

For security reasons, I am required to log-in as a non-admin user at work. When I need to install an application, I will have to switch to a different account with admin privilege. Recently, I had experienced two instances in which an installation is user dependent. So an installation for an admin user account does not apply to my non-admin user account.

Long March rocket (长征) is a family of expendable launch systems operated by China. Development and design falls under the auspices of the China Academy of Launch Vehicle Technology. In English, the rockets are abbreviated as LM- for export and CZ- within China. The rockets are named after the Long March of Chinese communist history.
