Pros and cons for different places to stay

China:

Pro:
Mediocre career path (IT sector).
Good housing and good food.
Close to home.

Con:
Chinese lifestyle.
Not so much freedom.
Chinese mindset everywhere.
Dictatorship. A lot of politics, censorship and restrictions.
Potential bad life quality due to pollution and unsafe food.
Isolated from the world.
Too entertaining. Hardly anyone is serious about anything.

Conclusion: OK to visit for short-term but may not be suitable to stay in the long-term.

US:

Pro:
Good career path (research).
High tech.
Good life quality.
Freedom.
Vast personal space.
Western style and mindset.

Con:
Few connections.
Far from home.
Not so good food.

Conclusion: the learning curve is high but good to stay in the long-term.

HK:

Pro:
Many connections.
Metropolitan lifestyle.
Close to home.
Good food.
Partially western mindset.
Small city. I know everyone. Feel safe.

Con:
Bad career path (if stay in IT sector).
High living cost. Bad housing.
Too materialistic and entertaining.
Crowdy and noisy. Very little personal space.
May easily get bored.

Conclusion: better than China but need sacrifice a lot of things (career interest, life quality). May need to consider other career options.

Conclusions: Both Hong Kong and US look good. But there is a trade-off between short-term benefits and long-term gains.

An Interesting Thread

I decide to write something outside latex, matlab, etc.

Yes I have been using GIMP a lot recently. Changing habit from Photoshop to GIMP takes some learning curve.

The interesting thing is, if you select some region from an image, and want to create a new image with that region (same size), what will you do?

This is the hotkey:

select->Ctrl+new->Ctrl+shift+V

Happy open sourcing.

Git Remove and Latex Bibliography

Sometimes you decide to add .gitignore in your git project in the middle, and you need to remove some files.

You can use the following command:

git rm *.aux(or blg/bbl/swp...)

To build bibliography, you need to follow the following steps:

PDFLATEX->BIBTEX->PDFLATEX->PDFLATEX
