Publicado por Admin en 10:17 AM 0 comentarios
Twitrratr gives us a different way to search tweets around Twitter. It detects if the Tweet is a positive, negative or neutral message.

You only need to write the keyword and Twitrratr will give you the results sorted inside three columns: positive, negative and neutral tweets:

It's not perfect, but it's an interesting way to see how good or bad people is tweeting about a specific topic or person.

Now Gmail suggests email recipients

Publicado por Admin en 10:55 AM 0 comentarios
If you send continuously emails to more than two persons at once, this tool could be useful for you. Go to Google Labs and activate the widget "Suggest more recipients" and save changes. Now when you compose an email, after writing two recipients, Gmail will suggest more recipients based on your history.

If you do not have an Gmail account, do not wait more for sign up. It offers many advantages and allows you to use Google services like Google Reader, Google Talk, Google Calendar, Google docs, and many more.

Microsoft no longer offers free technical support for Windows XP

Publicado por Admin en 10:17 AM 1 comentarios

Microsoft no longer offers free technical support for Windows XP Home Edition and Office 2003 users. Only the security updates will be distributed. This will affect companies that still sell computers with this operating system installed and, of course, to all users of this operating system.

I never used this service from Microsoft. When I have a problem with my operating system I look for information around the Internet.

Animated Sorting Algorithms

Publicado por Admin en 4:41 PM 0 comentarios
Sorting-Algorithms gives us an animation to illustrate how sorting algorithms work. An algorithm defines the steps to be taken to resolve a problem. Sorting algorithms, as its name suggests, aims to sort a number of elements. There are other pages that shows animations like this, but this one is the best I've seen.

Algorithms that includes the site are: Insertion, Selection, Bubble, Shell, Merge, Heap, Quick and Quick3.

Animated Sorting algorithms
We can vary the initial ordering of the elements, the can be: Random, nearly sorted, reversed or with few unique.

The webpage tries to show this:
  • How each algorithm operates
  • That there is no best sorting algorithm.
  • The advantages and disadvantages of each algorithm.
  • That worse-case asymptotic behavior is not the deciding factor in choosing an algorithm.
  • That the initial condition (input order and key distribution) affects performance as much as the algorithm choice.
