Rollback an update in Goolge app engine,

..i spent 10 minutes to figure out how to do it. So .. i decide to write it down in case of other use

Google App engine, MAC OS , Python

Google Document:

appcfg.py [options] rollback

Undoes a partially completed update for the given application. You can use this if an update was interrupted, and the command is reporting that the application cannot be updated due to a lock.

This is the address of my application :

/Users/Huy/Documents/web2pyforGAE_truyennganhay/web2py

Execution:

appcfg.py rollback /Users/Huy/Documents/web2pyforGAE_truyennganhay/web2py

Result

Application: truyennganvietnam; version: 2.

Server: appengine.google.com.

Rolling back the update.

Email: hello.i.love.it@gmail.com

Password for hello.i.love.it@gmail.com: 

Make sure you allow GAE to install Command type when it asks.

Done.

My first try with Web2py and Google app engine

1. Google App Engine
2. Web2py

Here's my first try with them:

When developer do designing job !!!

... i'm working on a project by my self so as it sounds i have to do all the work from coding to designing.

After a days of searching with a goal of creating very creative website design i actually give up. ^^

Do the designing part is so much hassle... which color for header? , which color for each column..etc it just simple out of reach for me .

So the strategy is: instead of trying to make something unique, beautiful by my self. I decide to copy Color-scheme from whatever website that suit my need... Yup...Easy.


here's some thing for reading if somewant whose doesn't know designing start to design a website.

http://answers.google.com/answers/threadview/id/290239.html
http://www.pagetutor.com/colorpicker/index.html
They provide very useful information about color designing.


 ...i skip that part and do searching then i found pretty cool designing color cheme website

I would go back to design part late when programming part is done.^^
