you can make money

Vadiraj — Fri, 18 Feb 2011 14:15:31 +0000

You can make money, only if you know exactly what happens after 3 months. And most of the people who made money knows this

Having clear cut vision of the future makes us one step ahead of others. If I know the future, I can use it for my advantages. As simple as that…

Simple comparison between Google and Amazon EC2

Vadiraj — Thu, 17 Feb 2011 15:59:01 +0000

I have tried both Google App Engine and Amazon EC2 Cloud. Here is my take on these two. My opinion is based on my experiment with Free Tier of services allowed by these two service providers. In case of Google, I only used free quota and in case of Amazon I used only t1.micro instance.

It is possible that as the load and computation complexities increases, there may be significant advantage and disadvantage over another.

Overall, if you are ready to spend around 15-20 bucks per month, you will get significantly better hosting environment than the wholesale webhosting retailers.

Feel free to add your opinions…

	Google	Amazon
1	No need to worry about instancing, storage and complex service offerings blah blah..	You have to plan ahead on kind of instance you would want and in which region you would place that instance. If you make mistake of selecting wrong location, you would end up paying hefty bandwidth charges among the storage and server instances.
2	There is no ssh access to the instance. It is a sandbox concept. You push your code and forget it. If you need special processing, it is not possible unless Google adds it to their platform.	It provides SSH but is painful to set up ssh on 443 port. I couldn’t set it up to run on 443. The port is reserved for HTTPS, always!
3	You have to code only in Java or Python. Even the libraries are restricted. If you are planning for PHP or ruby on rails based website, forget the Google.	You have full control over Webserver, App servers and the programming language of your choice. Best of the CMS are based on PHP. So most of the small websites would tend to adopt EC2.
4	It has a file limit of 3000 files. Pretty much useless, if you try to build decent application.	You will get pretty decent amount of storage space. But they eat money on the transfer of data and bandwidth.
5	Provides Eclipse plugin to develop GWT and deploy in AppEngine	Provides Eclipse plug-in for server maintenance and BeansTalk (similar to GWT) development

Quick start up of Eclipse

admin — Fri, 11 Feb 2011 01:45:00 +0000

Eclipse loads useful and useless plug-ins during it’s start up. That makes us to wait looking at the flash screen for quite sometime. I found out this trick to make it quicker and faster during start up.

Open Window->Preferences, and expand General category. You will find subsection ‘Startup and Shutdown’. Expand it and uncheck all those plug-ins which you don’t use frequently or you think which are hogging your precious memory space. The next restart should show you some improvement. If not, change your computer….;)

Parsing XML with namespace

How to parse XML tags with namespace?

Look at the below example, I want to fetch info. How do I do it with Java or Groovy?

Unable to compile Resources directory

Vadiraj — Wed, 09 Feb 2011 16:06:52 +0000

If you are using Snecha GXT UI libraries for GWT app and encounter ‘unable to compile Resource’ module or ‘Unable to find entry point for Resource’ module’

Check these things

‘resource’ directory is under web application root (war directory under Eclipse project structure)
Check if you have added com.extjs.gxt.samples.resources.Resources.gwt.xml under GWT->Compile->Add Entry Modules list. If so, remove the module entry and recompile.

Cleveland Snow Videos

This is the video taken after night long winter storm in Cleveland. Although, it hasn’t affected much like other places, still it’s a worth video taping…;)

This own is on my way to 271 S on Chagrin Blvd

This is own 271 S on my way to office in Barberton.

Any money spent in capitalism is a good money

Vadiraj — Sat, 13 Nov 2010 00:35:20 +0000

Any money spent in capitalism is a good money.

No need to debate over, if you are spending your money for good cause or bad cause. Just spend it. Your money is good, as long as you spend it.

As long as you can sell your justification to others, you can do whatever you want

Attributes defined only in child types

Vadiraj — Fri, 12 Nov 2010 15:39:24 +0000

How do you get the attributes defined only for the child type in Enovia?

print type select attribute dump |;

This command will give you all the attributes associated with the type including those inherited from its parent.

Use below command to get all the attribute defined only for the type in question.

print type select immediateattribute dump |;

Developing a search based application

Vadiraj — Sun, 10 Oct 2010 14:09:29 +0000

Known as SBA, Search-based Applications employ semantic technologies to aggregate, normalize and classify unstructured, semi-structuredand/or structured content across multiple repositories, and employ natural language technologies for accessing the aggregated information.

To give you an idea, let us say restaurant directory that consolidates source data including database content (restaurant listings in the directory database), Web content (photos, details like opening hours, prices, menus, payment options, etc.), and user-generated content (opinions, ratings, reviews, blogs, etc., also gathered from the Web), with sentiment analysis applied on the aggregated content. It also incorporates geospatial data for mapping. The result is an ultra-rich directory that synthesizes a massive amount of information into a coherent, at-a-glance consumer dashboard.

What is semantic technologies?

In a traditional Software Applications, meanings and relationships must be predefined and “hard wired” into data formats and the application program code at design time.

semantic technology encodes meanings separately from data and content files, and separately from application code.

This enables machines as well as people to understand, share and reason with them at execution time. With semantic technologies, adding, changing and implementing new relationships in a different way can be just as simple as changing the external model that these programs share.

What is Natural Language Processing?

Natural Language processing (NLP) focuses on the interactions between computers and human (natural) languages and a way to human-computer interaction. It means as the computer is aware of the situation and outside world.

SBAs are used in various domains:

Enterprise Business Applications: Such as Customer Relationship Management (CRM), Enterprise Resource Planning (ERP),Supply Chain Management (SCM), Compliance & Discovery, and Business Intelligence (BI)

Web Applications: Typically, B2B, B2C and C2B applications that mash-up data and functionality from diverse sources (databases, Web content, user-generated content, mapping data and functions, etc.)

Database Offloading: In this case, SBAs are used to provide an alternate means of accessing database content that is non-intrusive to source systems

Data Migration: SBAs are sometimes used as a temporary platform to ensure continuity of information access during large scale migration projects

Information Lifecycle Management: SBAs are used as a complement to Data Management ecosystems, such as those used for Product Lifecycle Management (PLM) and Master Data Management (MDM)

With this background I am going to develop a search-based application pilot in coming months.

Pilot Objectives:

Demonstrate the working knowledge of the Search-based application eco system.
Understanding its strength and weakness
Analyse the system with respect to Small and Medium Enterprises IT requirements.
It outlook with respect to PLM system.

I am going to publish the articles as I proceed with this pilot.
