Greedy Web Applications

I was very confused about what would be the main topic of this entry.
At the beginning, I was amazed about this awesome demo developed by Adobe company. It shows a "live" transmission of a cycling race stage. It displays a well orchestrated set of web services integrating GIS, AJAX and multimedia technologies.

Today, we can found an impressive amount of web applications as useful as standalone applications, but they have serious performance problems.
I have mentioned how the browser now is our new productivity environment and I can enumerate a
popular set of "web applications" such as:
gmail, youtube, google reader, scribe, zotero, among others; but they provoke an important performance decrease in my laptop.

At this moment, there are a respected number of computers with a low profile performance, further, the industry are producing them with high succeed, hence it's convenient consider seriously to develop profiling tools for environments where the web application are developed.

Patch your Fedora Distribution

Today, a friend of mine, alert me about an exploit found in most of the Linux kernels.
Promptly, I went to and look for "kernel exploit linux". I found this in,
The announcement suggests that systems based on Ubuntu and Debian are vulnerable, but my FC7 distribution is vulnerable, too.
However, 30 minutes ago, I updated my kernel, using "Software Updater" from the Gnome menu, and the problem was fixed.

So, lets update your software.

Tools for Writers

The last year ends with a profound desire to becoming me in a great writer.
Undoubtedly, it's a challenge and different knowledge areas demand educated people that expresses his ideas in a clear and concise way.

Two key elements leverage the development of the new writer, I thought.
  1. An indomitable personality and passion for sharing his ideas through written word.
  2. A suitable set of writing tools.
Shortly, I will speak about the second item.

Thirty years ago, maybe, the typewriter machine was the suitable tool for a writer.
Twenty years ago, the desktop computer leverage the writing process to another level, saving paper and letting a process writing more iterative.
Today, powerful advances in web technologies bring us browsers as the almighty tools. As consequence, all the things that you as a geek can be accomplished from your web browser: read e-mail, read news, watch videos, listen music, chat, make a phone calls, among others.

My prefered browser is Firefox. It's an open source browser with a large add-ons base that brings the navigation process to next level.
So, as follow I will mention a couple of these add-ons:

  1. Zotero: It's a free, easy-to-use extension to help you collect, manage, and cite your research sources. Certainly, it's a powerful tool for the researcher. It will be hilarious when has support for PDF documents, too.
  2. Scribefire: It supports the blog publishing process to your favorite blog site from your web browser.
  3. Split Browser: You can split browser infinitely, as many as your RAM and your screen allow. It's a useful tool for editing over multiple-sites on a single screenshot.
Next time, don't underestimate what your browser can does for you.
