connecting Xcode4 with SVN server

Are you using xCode 4 with Snow leopard?

In this case, I solved like this. I think this caused by a bug  in Xcode or permission problem in Mac or something though.

1.Launch  the terminal in your mac,
2. type in the terminal   svn ls svn://svnserverURI/Repository
3. And it will ask you password (This is your Mac's password), and then your ID (svn repository ID) and password (svn repository PW) again
4. once you typed correctly, it will show you success.
5. Go to Organizer in Xcode, and hook up repository, then you will see ID/PW and No Revision updated on the work space

Team work and productivity.

Teamwork is the ability to work together toward a common vision.
The ability to direct individual accomplishments toward organizational objectives.
It is the fuel that allows common people to attain uncommon results.
~Andrew Carnegie


In my program at the Carnegie Mellon University, we highly promote this motto - "learning by doing" , like Andrew Carnegie said, we highly value on "uncommon results" from teamwork. 


As far as Web technologies and network has been evolved, it has been way easy to get oneself exposed to any educational environment. People could learn how to install software and tips from blogs, Youtube, iTunes university, even from limited 160 words from Twitter. It's been hard to add more value added service in education area without building environment to share, think and conclude together. 


I totally agree with Andrew Carnegie's Teamwork spirit, and want to promote this spirit to my classroom as well to bring more unforgettable moments to my students. 


I see some students feedback regarding to team work and productivity. I see some complaints about slackers. However, I've observed tremendous outcomes from any teams in the class room. They could not reach those results without inspiring , challenging, arguing and debating each other. That being told, I wish my summer lecture going well to bring same team spirits for SE , ISR and INI students.  I do believe their potential ability to bring their best efforts to inspire each other as well as myself, other guest judges and guest lectures. I hope they could build strong companionship each other and learn each other. Can't wait to see it. 

Work, Family, Health, Friends, and Spirit - Five balls by James Patterson

Imagine life is a game in which you are juggling five balls. The balls are called work, family, health, friends, and integrity (your spirit) . And you're keeping all of them in the air. But one day you finally come to understand that work is a rubber ball. If you drop it, it will bounce back. The other four balls–family, health, friends, integrity–are made of glass. If you drop one of these, it will be irrevocably scuffed, nicked, perhaps even shattered. And once you truly understand the lesson of the five balls, you will have the beginnings of balance in your life.

Imagine life as a game in which you are juggling some five balls in the air. You name them - Work - Family - Health - Friends - Spirit, and you're keeping all of these in the air.

You will soon understand that work is a rubber ball. If you drop it, it will bounce back. But the other four balls -- family, health, friends and spirit are made of glass. If you drop one of these, they will be irrevocably scuffed, marked, nicked, damaged or even shattered.

Totally agreed. To me my spirit is the most important thing as well as my family - actually Mom. She needs lots of attention before going back to nature. I know as a human being, we need to answer the nature's call, my mom will do the same at most in 50 yeas. Sometimes I was mean to her, even though I always aware of her problem, but I am a human being as well....so sometimes I was not friendly to her. I should keep this in mind more seriously. Time and resources are limited, and I should focus on something important in my life rather than other's criteria. Focus!

Goal for this year.

1. Appreciation : to earn the appreciation of honest critics, to appreciate beauty, to find the best in others;
2. Respect : to win the respect of intelligent people
3. Trust : to build trust with at least two friends and two coworkers 
4. Individual growth
5. Companionship with co-workers

Recall from 80/20 principle , the village theory

From Chapter 12,  The 80/20 Principle: The Secret to Success by Achieving More with Less” by Richard Koch

“Apparently, the common pattern of people in any society is to have two important childhood friends, two significant adult friends and two doctors. Typically, there are two powerful sexual partners who eclipse the others. Most commonly, you fall in love only once and there is one member of your family whom you love above all others. The number of significant personal relationships is remarkably similar for everyone, regardless of their location, sophistication or culture. This has led to the anthropologists’ ‘village theory’. In an African village, all these relationships happen within a few hundred meters and are often formed within a short period of time. For us, these relationships may be spread all over the planet and over a whole lifetime. They nonetheless, constitute a village which we each have in our heads. And once these slots are filled, they’re filled forever. The anthropologists say that if you have too much experience, too early, you exhaust your capacity for further deep relationships. This may explain the superficiality often observed in those whose profession or circumstances force them to have a great number of relationships, such as salespeople, prostitutes or those who move house very frequently.”

For This reason we should be careful in choosing our relationships and try to fill these slots with the most valuable people we can find and not rush to fill them.
