Life just gets More Audible with AUDACITY

codewurd — Fri, 02 Oct 2009 16:36:11 +0000

/* Click here to see the entire list. */

One of my favourite software that I cannot ignore .

AUDACITY is a really cool software especially for those who want to record their voices , instruments etc and don’t want the hassle of sopphisticated audio editing software packages.

As a musicain I have recorded loads of melody using audacity.

The best advantages.

It is very simple and has avery short learning curve.
Its a cross platfrom software, (works in Windows, Linux ,MAC etc)
Its an open source and its free.
It has a numbe of effects(Like wahwah etc).
The recording can be expoted as mp3 file.
This is a screenshot of the effectsSo if you want to compose music by yourself you can compose it in layes. First recording the tempo, then the rythm the solo vocal or addition parts. (For example check out : RoyRock.mp3)One can even import audio and edit and add effects to it.

Some cool effects

All thats left to say is.

AUDACITY!!!AUDACITY!!!AUDACITY!!!

4.Displaying XML using javascript

codewurd — Fri, 02 Oct 2009 15:45:27 +0000

/* Click here to see a list of all XML tutorials */

A number of porgramming and scripting languages like VB.net javascript etc have the ability to read XML.

While reading an XML files using javascript, one must remeber which browser it is to be displayed in. Different browsers read XML in different ways.
For eg IE explorer uses the ActiceXObject while Firefox,Opera on the other hand uses document.implementation.createDocument method.
If you are not sure which browser will be used, then use both methods.

Now for the company .xml

company.xml

Jack
Manager

John
CEO

so open notepad(or any other text editor):

company.html

3.XML Schema

codewurd — Thu, 01 Oct 2009 17:15:38 +0000

/* Click here to see a list of all XML tutorials */

Once again,XML is only used to DESCRIBE DATA.

Hence we need to understand two more components while learning about XML:

XML DTD
XML SCHEMA

these are used for defining the XML Structure

XML schema
This tutorial will Just give you an short and sweet understanding for more detailed Info see: w3schools

let us create a schema for the company example:

Hence we get :
company.xsd(save as .xsd )

company.xml


         xsi:noNamespaceSchemaLocation="company.xsd">

2.The realistic Funtastic Virtual Box

codewurd — Thu, 01 Oct 2009 15:30:34 +0000

/* Click here to see the entire list. */

we’ll a lot of people are becoming familiar with software that virtually emulate hardware. Like vitrual CD ROMS etc

Now lets suppose you’ve heard a new OS(Operating system) and would like to give it a try, but at the same time you are not sure if installing it would be the right idea.Then Virtual Box is for you.

For those who have not heard of this concept before

Virtual Box and other System emulators provide a method of installing Operating system witthout affecting the system.
For example, I am currently running XP from a very ,very………long time , now i have found that Linux mint is as good. However I have very little knowledge of linux, so before taking a direct leap into the unknown. I’d like to test it and learn more about it. So I can install it on a Virtual Box

Are there other emulators like Virtual Box ?
Yes. infact there are. Currently many people many people are using VMware. It a pretty good software itself but It not free(though the VMplayer is free, but does not contain much features and cannot create a VM ). Virtual Box on the other hand is a freeware by Sun Microsystems . A host of operating system can be installed on it like Windows(XP ,Vista), Linux,MAC,Solaris etc.

Virtual Box(To Download click here and download for your currrent OS)
It starts quickly. Multiple OS can be installed.Has some really good features:

VBox guest Addition – similar to vmware tools , once installed you can easily switch between Host OS(you main system OS) and guest OS(you virtual OS).The guestaddition is a must install after the OS is installed.
Seamless window- one really cool feature that helsp you work on both your real system OS(Host OS) as well as Virtual system OS(guestOS).Check out this screen shot to get an idea.

Note: the window frames in black belong to Linux, the ones in blue belong to Winows XP. also notice the two bars at the bottom of the screen.
Here I have installed Linux Mint On XP to test it before installing it as my real OS.

There are a lot more features to explore.

For more idea abbout the VBox check out the End-user manual at virtualBox.org :To Click here

2.Understanding XML DTD

codewurd — Mon, 28 Sep 2009 16:09:02 +0000

/* Click here to see a list of all XML tutorials */

Now that the basic syntax of XML is understood from previous post . (See Wrting an XML Document)

Let us keep in mind the example:

company.xml

Jack
Manager

now XML is only used to DESCRIBE DATA.

Hence we need to understand two more components while learning about XML:

XML DTD
XML SCHEMA

1. XML DTD(Document type definition ) – as the name suggests it is used to define the Data (which has already been described in XML syntax)
-while defining each of the user defined tags become an ELEMENT

eg.

[

]>

Now the DTD can be placed in two ways

Internally, inside the XML Document
Externally as a “.DTD” file and a reference made to it from outside.

1.Inserting XML internally

company.xml

[

]>

company.xml

Jack
Manager

John
CEO

Thus through the definition(DTD) it becomes easy for a XML parser to understand the type of XML Document content and process the XML document.
And hence it is called a “Valid Document” as well as a “Well-formed Document”

For more Information refer : W3schools

1.Writing an XML document

codewurd — Mon, 28 Sep 2009 01:57:40 +0000

/* Click here to see a list of all XML tutorials */

Q Why XML why not directly write to a Database file ?
Ans

.XML can be written in a simple text file which not only makes it portable but also easily accessible.
Other Databases like MS Access, SQL (though they provide a nice user friendly interface ) require to be installed before they can be used. Consider for eg I saved a file in MSAccess(.mdb) and shiffted to a Linux system which does not have support for that file so it proves useless. If instead I can use xml and store it in a plain text file,then I could view ,edit and store it.
XML requires simple text editor , and hence can be used over all most all platforms even older OS’s
IT is easy to decode XML data and using some common sense it can be used in any programming language to display Data.

One way of understanding XML is to view it as a Tree structure represented in text format

Consider the above diagram.

The company is the root

The company has a child nodes -Employee
Employee has child nodes -Name and Post
The company has another child nodes -Employee2
Employee2 has child nodes -Name and Post

Now we represent it in XML in a similar way
Here each node becomes an Element.
(Remeber the elements are case sensitive)

Jack
Manager

John
CEO

Now that we have the basic understanding we’ll learn how to implement it.

We also have to mention the XML version we are using ,

eg.

hence we have our final XML syntax file

company.xml

Jack
Manager

John
CEO

1.A new OS dawns and it tastes like MINT

codewurd — Sun, 27 Sep 2009 17:23:58 +0000

/* Click here to see the entire list. */

Well this was recommended by my good friend and the brain child of this Blog(name has been witheld for security reasons…..haha).

Somedays ago I had just downloaded OpenSuse11.1(64bit) and was trying in on VBox. Being comparitivly new to managing Linux , OpenSuse seemed a wee bit complicated. I had a lot of problems trying to install the VBox Guest additions(enhances use of virtual Box). So after a few days of trying. I decided to take up the offer and try LINUX MINT 7.Got the CD from a good frind codenamed “Mandrake”. It turned out pretty well.

Easy to install (It run live direct from its installation DVD and can be tested before installing )

A sufficienttly good looking inerface, easy access to almost all necessary applications(better than windows).
Even the guest additions got instatlled properly.

I has a feature mintInstall through which other packages can be installed(like winedoors etc, will delve into these later)

What is the biggest paradigm change in Enterprise Software?
Linux Kernel, of course. Created by Linus Torvalds, in 1991, helped open-source developers collectively craft a viable alternative to Microsoft operating systems. It is said that the Linux kernel contains 8.2 million lines of code, with approximately 86 lines added every hour. New releases occur every 2.6 months (unless otherwise marked).
