Posted By Venu Thomas

The series of promotional videos for Office 2010 trying to launch the software as the plot of a film of action, are fun.

There’s a part where you see the tomb of Clippy, the Office tool from which it is often mocked, he has been absent in recent versions of Office software.

It also includes an interview to find the missing sources. However, the woman tells him in captivity are among “Arial” and “Wingdings”

Doodle.js, library for working with canvas

Posted By Venu Thomas

Doodle.js is a library that allows us to easily work with the element <canvas /> and everything that entails. With a similar aesthetic to jQuery, drawing on the canvas that is <canvas /> is as simple as this:


  <head>
  <!--[if IE]><script type="text/javascript" src="http://explorercanvas.googlecode.com/svn/trunk/excanvas.js"></script><![endif]-->
  <script src="./doodle-0.1.js" type="text/javascript"></script>
  <script type="text/javascript">
    function init() {
      (function(oo) {
  oo.canvas('#my_canvas');
  oo.rect({x:25, y:25, width:50, height:50}).draw();

})($doodle);

    };
  </script>
  </head>
  <!--init() is called when the canvas is ready for us.-->
  <body onload="javascript:init();">
    <canvas id="my_canvas" width="600" height="400">
      <p>Fallback: Canvas element is not supported in this browser!</p>
    </canvas>
  </body>

Examples

Do not miss some of the examples available on the homepage of the library:

Proposal subtitle for HTML5 video tag

Posted By Venu Thomas

In Ginger’s Thoughts I read a very interesting proposal which I believe is that in just a proposal. Although the idea is very good and it might be interesting to have this in the new HTML5. The proposal is for December 2008 and so far no developments.
The idea is to include the tag HTML5′s ability to handle subtitles:

<video src="http://example.com/video.ogv" controls>
<text category="CC" lang="en" type="text/x-srt" src="caption.srt"></text>
<text category="SUB" lang="de" type="application/ttaf+xml" src="german.dfxp"></text>
<text category="SUB" lang="jp" type="application/smil" src="japanese.smil"></text>
<text category="SUB" lang="fr" type="text/x-srt" src="translation_webservice/fr/caption.srt"></text>
</video>

As we can see in the above code, we would be including the text tag that would allow us to establish the lang attribute of the subtitle language and select it from your control in your browser (the preset default language of your browser) .

The tag <text />
Only indicate the location of the subtitle file to load src indicating the language lang and type type of a subtitle that we carry.

For now …
At the moment we can make use of SRT jQuert to simulate the result with Javascript.

<!-- Javascript -->
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" src="jquery.srt.js"></script>

<!-- HTML  -->
<video src="http://example.com/video.ogv" id="video" controls>
<div class="srt"
data-video="video"
data-srt="http://example.com/video.srt" />

The idea is interesting when the films arrive officially to the Internet. Huh?

Video: Autodesk Labs Inventor Fusion: Overview [04:07 min]

Autodesk announced its 2010 product line with several new features. Is the market leader in CAD with its AutoCAD product, which is the benchmark since 1982 and has not lost its validity. The company has 9 million users and 700,000 companies registered as clients, apart from recognition as the second most pirated software on the market.

The version of AutoCAD 2010 brings new features:
* Import and export in PDF format
* 3D Geometries
* Parametric Drawing
* 3D Printing

The Autodesk product family offers solutions for architecture, industrial design and manufacturing, with specific products in the area of design, simulation and visualization. Architecture, Civil, Electrical, Map3D, Mechanical, MEP and the P & ID product family, all with first name and surname AUTOCAD 2010. New in the 2010 family is the consistency between all the products in the family, both as a user interface formats.

The real news is Autodesk Inventor Fusion. This is a completely intuitive CAD for the production of prototypes, which is available to anyone who wants to test free of charge. Autodesk is an experiment in which they are looking for the users to decide the use that will give the software and even paying for it. We created this software may be stored in DWG format, which is compatible with any CAD software market.

Parametric design fuses and direct without any annoying toolbars and complex: it is done with mouse movements, as if it were taken with the hands.

PostgreSQL 8.4 maintains its distance with rivals

Posted By Venu Thomas


The Group PostgreSQL Global Development has released version 8.4 of the database of open source with advanced features. There are nearly 300 improvements to administration, programming and query language opening up new possibilities with this database.

Some improvements are:

* Restoring the database using parallel processes, accelerating the recovery of a back up to 8 times compared to the previous version.
* Column privileges, to control access to a greater level of detail.
* Language settings and management for database. To be able to select the most appropriate depending on the language that is required.
* Update 8.3 to 8.4 with minimal downtime
* New tools for monitoring consultations, delivering information to managers to know what is happening in the database.
* Implement advanced features of ANSI SQL: 2003 which allow complex queries into a single expression which previously required several.
* Improvements in stored procedures, for example using default parameters in the statement or list of arguments of variable length, the style C + + / Java.
Besides the new features, this new version includes improvements to the strong performance, particularly in complex operations.

While there are other databases of open source with a large base of users as MySQL, PostgreSQL orientation has always been to implement the features that make face to face with advanced databases such as Oracle. In this issue again The project has made it clear what distinguishes PostgreSQL jurisdiction in the world of open source.

Detection of faces on canvas with Javascript

Posted By Venu Thomas

Detect faces and is not just for Google Images. Now you can implement it on your website using Javascript and the canvas properties.

Venu

How it works?

To do this we need to work only 2 files in our <head />

<script type="text/javascript" src="dat.js"></script>
<script type="text/javascript" src="detector.js"></script>

Dat.js the file shows how to detect and detector.js the file has the logic of the script can detect faces in any photo.
1 can detect faces in the photos, the process becomes slower depending on what we choose (of course).

1 Face

?View Code JAVASCRIPT
face_detect_one( document.getElementById("myCanvas") );

Multiple Faces

?View Code JAVASCRIPT
face_detect_multi( document.getElementById("myCanvas") , progress_callback, result_callback );
function progress_callback( StepsCompleted, TotalSteps){
....
}

Answer

The response functions that returns the values we obtain a rectangle that contains the person’s face.

?View Code JAVASCRIPT
var myCanvas = document.getElementById("mycanvas");
 
var result = face_detect_one( myCanvas );
if (result) draw_rect(result, myCanvas);
 
function draw_rect(r, myCanvas){
	var CanvasContext = myCanvas.getContext("2d");
 	CanvasContext.strokeRect( r.x, r.y, r.w, r.w );
}

Microsoft Web Platform Installer & Windows Web Application Gallery !

Posted By Venu Thomas

Among the initiatives that Microsoft has to facilitate the design and creation of Web applications, this week we find two important components focused on that idea: the Web Platform Installer and the Windows Application Web Gallery. In the case of the Web Platform Installer, we find that Microsoft continues to evolve this utility you can install at a stroke a lot of ingredients we might need to build our web applications. In the Windows Application Web Gallery, we have a resource center where people can find applications and free technology. NET and PHP available for download. But let us see in detail each of these applications.

Web Platform Installer


As I said, Microsoft has just released the first beta of version 2.0 of the Web Platform Installer, which allows us to form a unified set of components that make up the stack of a typical web platform, and all this in just 1 MB. Among the components included (and whose installation is fully customizable), we have:

* Internet Information Services (IIS) 5.1 on Windows XP SP3.
* IIS 6.0 on Windows Server 2003 SP2.
* IIS 7.0 on Windows Vista SP1 and Windows Server 2008.
* SQL Server 2008 Express.
* .NET Framework 3.5 SP1.
* Visual Web Developer 2008 Express Edition.
* IIS Extensions including:
o IIS 7 Media Services 3.0.
o IIS7 Administration Pack.
o Database Manager for IIS7.
o WebDav 7.5.
o FTP 7.5.
o FastCGI for PHP support on IIS6.
o URL Rewrite.
o IIS 7 Application Routing.
o Web Deployment Tool for IIS.S.
* ASP.NET and features such as ASP.NET MVC.
* Silverlight Tools for Visual Studio.
* The Community Version of PHP v5.2.9.

Windows Web Application Gallery


In this case we have a portfolio of applications and ASP.NET PHP fully tested as DotNetNuke, DasBlog, Graffiti, Drupal, WordPress, phpBB (incidentally, another proof of the shift to open source that Microsoft is doing) for lists download and install.
