jupyterlab halt in "[1/4] 🔍 Resolving packages..."

In the end, it's the node 10 compatibility issue with yarn 1.6.0 in jupyterlab

Downgrade into Node 9 in Mac would resolve this...

The first change of this year is comming soon

Finally, I achieve the goal I made in the student era, joining in ///.

No matter how many difficulties in front of there, we can made it.

I'm not the guy who believes destiny which you can only obey, while I believe there is one thing called faith which you can control. Anyway, it's feels great to make things done.

Not only exciting,  there is some kind of melancholy falling in my mind, for such a great team, for such an enjoyable group, for my elapsing pre-career time.

At the same time, wish  healthy comes along with us.

Keeping on enjoying life in BJ.

Just using this to spent the time that I do have post to say....... don't blame me, I'm boring.

Waiting on the World to Change

Mr. Obama use "Change" as the president-elect's motto, at the same time, this character "变" is declared as Japan's character of the year, though this is definitely a Chinese character.

Though, for me "Change" is exactly the topic of 2008.

• I spent almost the coldest two winners of my life this year(both in Chengdu during the whole Jan. and in Dec. when I am here, in Beijing ).
• We were survived in the Earthquake, facing lots of situations which reflect who you are. This changed my view of life.
• I was finally graduated from school. However, a little bit difference from what I expected. This is the change of my role in this world.
• There are  so many changes in this year that i can not even list all of them in this post. Change different departments, career, time management, development platform......
• Wish in the next year, there will only be surprises, no unexpected changes, anymore.

Farewell, 2008
