Gmail keyboard Shortcut

Firefox + Gmail is a good solution to mail, better than Windows Mail, Outlook, and Mozilla Thunderbird. Mac Mail is the best but I lost my mac.

With those shortcut, you can mange Gmail efficiently. (Sorted by my usage.)

EMacs+AUCTex

This is the best solution for writing Latex. There is a fundamental question for all latex editors: how to jump between latex source file and output dvi/pdf file? In Mac, TexShop provides a simple and good solution: Apple + CLICK will try to match locations of source file and pdf file. Lyx and Texmacs are WYSIWYM editors. The price you pay is the slow typing speed (the desirable typing speed will simulate your thinking) and difficulty of collaboration. Preview-latex, a built-in package of AUCtex, strikes a balance. Let me copy the following paragraph from preview-latex manual:

WYSIWYG (what you see is what you get) sometimes is considered all
the rage, sometimes frowned upon. Do we really want it? Wrong
question. The right question is _what_ we want from it. Except when
finetuning the layout, we don't want to use printer fonts for on-screen
text editing. The low resolution and contrast of a computer screen
render all but the coarsest printer fonts (those for low-quality
newsprint) unappealing, and the margins and pagination of the print are
not wanted on the screen, either. On the other hand, more complex
visual compositions like math formulas and tables can't easily be taken
in when seen only in the source. preview-latex strikes a balance: it
only uses graphic renditions of the output for certain, configurable
constructs, does this only when told, and then right in the source code.
Switching back and forth between the source and preview is easy and
natural and can be done for each image independently. Behind the scenes
of preview-latex, a sophisticated framework of other programs like
`dvipng', Dvips and Ghostscript are employed together with a special
LaTeX style file for extracting the material of interest in the
background and providing fast interactive response.

Linux Command: Screen

Screen is a terminal multiplexer that allows you to manage many processes through one physical terminal. Each process gets its own virtual window, and you can bounce between virtual windows interacting with each process. The processes managed by screen continue to run when their window is not active.

Screen offers the ability to detach from a session and then attach to it at a later time. When detached from a session, the processes screen is managing continue to run. You can then re-attach to the session at a later time, and your terminals are still there, the way you left them. It is handy because, with screen, you can launch your long program, leave it running on a lab computer, logout and go back home. Wa... Is it what you want in many cases?

How to use it? Run screen first on your terminal and then press "CTRL + A D" (CTRL A, CTRL D) to detach from the screen. Then you can do what ever you want, like logout and go home to have some fun. To attach back to the screen, just use "screen -r". For details, you might need to look at its manual.
