I’d like to disabuse early-career grad students of certain misconceptions...
You are rarely the best judge of the most important material or best presentation strategy for your talk. Corollary: Give one or more practice talks.
Writing is much harder than you think. Corollary 1: You are not that great a writer. Corollary 2: If you don’t have a solid draft 1-2 weeks before the conference deadline, you’re starting with 2 strikes.
80% or more of submitted papers are rejected. Corollary: You need feedback from colleagues and outsiders to improve your paper. A poor way to get feedback is to submit the paper, wait 6 months, and get a rejection with cryptic reviews. A better way is left as an exercise to the reader. (Thanks to Mike Franklin for this particular way of looking at the “get feedback” issue.)
When you write up your work, remember that nobody cares what you did but only why it advances the state of the art. Edit accordingly. Corollary: edit an outline and paragraph map before you start writing. It’s much easier to rearrange/eliminate at this level than at the prose level.
The reviewer has 20 other papers waiting to be reviewed and is looking for a reason to set yours aside and move on. Corollary: your job is to ensure no such opening is provided—whether by unsupported statements, poor writing, rambling style, etc. Your goal is not that your work gets the approval of your advisor, but the approval of the research community, as represented by the (usually anonymous) reviewers who will be evaluating your paper.
Your advisor can bring her/his experience to bear and give you advice (hence “advisor”) on how to maximize the likelihood of this, but don’t mislead yourself into thinking that your goal should be to please your advisor. If the community is pleased with your work, chances are excellent your advisor will be too. Corollary: Get lots of feedback on a paper from people other than your advisor—i.e., people representative of the reviewers who’ll evaluate it—before submitting it.

Letters frequencies in different latin languages
Each language have words and letters that are most used, as like as the reciprocal. I like to study the details of a keyboard, starting in how it is made and ending up in the keyboard layout. I am a Dvorak layout user because it allows me to write most of the words without changing too much rows and alternate hands. During my reading about layouts, I came across with this graph that shows the frequency of the letters in different latin languages. Enjoy the image.

Editor relapse
Today I started again to use eclipse. cough, cough. I am sorry, I mean emacs. It is still a powerful editor.
If you start to question which editor should I use, this is the most accurate graph that will help you decide.

Is Apple going down?
Is my impression, or Apple is going down slowly? Steve Job was the soul of the brand, but in the new Apple generation, the company seems to insist in using Steve Job persona during the products presentation. The brand seems to have lost its momentum, and now I don't see no one like Steve Job to lift the soul.
My advice to Linux users that want to sell their soul to Mac is, stay away from the temptation. You can regret in the future.

Somewhere in the time you always think if you should use the printer from the company, or from the university to print a book, to print flyers, or any other stuff for your personal use. This instructions might help you to decide if you should click the print button from your computer.
