bibtex is a good thing to have

1. Download "jabref" (you can google it), then install. It works on Windows, OSX and linux ...

2. Learn how to use jabref? You can google it. There is a video about it. I like this link.

3. You can export it to html and even for MS word!! Well, I guess this little thing was born for tex, so there is no problem for latex users.

Neumann reported his car accident

Despite being a notoriously bad driver, he nonetheless enjoyed driving (frequently while reading a book) - occasioning numerous arrests as well as accidents. He reported one of his car accidents in this way: "I was proceeding down the road. The trees on the right were passing me in orderly fashion at 60 miles per hour. Suddenly one of them stepped in my path." (The von Neumanns would return to Princeton at the beginning of each academic year with a new car.)

Arbitrary parameters

With four parameters, I can fit an elephant, and with five, I can make him wiggle his trunk. -- Johnny von Neumann.

wireless in ubuntu

I changed to Ubuntu for no reason. Just want to try something different. It turns out to be a happy (and easy) change. The only thing hit on me was the wireless network. It couldn't "easily" (I mean, with a lot of my help, it could) find hidden wireless access point. But University only give me hidden wireless. A little bit search lead me to the following solution:
install wicd. google wicd will show you everything.

It is simple again. I like it.

Oh, one more thing, ubuntu is an OS and only an OS. It has not many software come with it. If you are a researcher, like me, you need to install (it is easy though) all softwares that you need. A short list for me:

gnuplot
vim (the default one is too basic)
xifg
compiz-fusion (for amusing your windows friends, maybe not anymore with vista)
pdftk
. . .

Difference of "change line mark" between windows and unix

In unix, line ends with a new line charactor, i.e. 0x0a.

In DOS/Windows line ends with a carriage return and new line pair, i.e.
0x0d0a.

In your case, every line ended with a carriage return, i.e. 0x0d, which is
displayed as '^M' in vi.

You need to replace every '^M' to new line in vi with the following command:

:%s/^M/\r/g

Note: ^M is entered as pressing 'v' and 'm' while holding 'Ctrl'.

OR :%s:\r:\r:g
