A short enjoyable trip to Kerala and Tamil Nadu..

2011-03-12T19:52:00.001-08:00

avi's been busy with his work lately and me and veda were also bored of the routine.So we decided to go on a vacation ,not very hectic and a place where we can get veda her food.So we planned a Tamil nadu-Kerela trip..we went to coimbatore,took a taxi and went to Malampuzha dam in Palakkad or palghat.the dam was closed so we didnt had much to look for.

We went to Gurvayur-the abode of Vishnu..it took us 2 1/2 hour for us to reach there.in the way we have passed Thrissur, which is called as the cultural capital, had lunch there and moved on. A occasional sight was a lorry full of animals. Later the driver told us that they are going to be slaughtered as beef consumption is pretty high in Kerala. it wa s kerela style designed temple the traditional hut style..the temple was not as rushed up as we thought but it still took us 2hours for darshan..lot of waiting time..but the lamps lit in the temple just put u in another world.each side of the wall of the temple has nearly 700 lamps..well they didnt lit up all the lamps of the temple till we were gone..but we saw at least 1500 lamps beaming on our face that night whch was wonderful..the gents are allowed for darshan only in their dhotis and women in their saris..that thing we knew but one thing we didnt know was children under the age of 5 were not allowed into the main temple as they do not have toilet training..it was a bit shocking and sad as our darling could not see the deity but then we had to abide by the rules..so we took the darshan in turns.

we were over with the day...next day we went coimbatore local sight seeing..we went to isha yoga ashram founded by sadguru jaggi vasudev.it was very serene and beautiful in the middle of large teak woods..th most amazing thing there was the dhyana linga ,a wide circular room with a huge shiv ling .the whole room was cut in perfect sphere thus enhancing the power of the shiv ling..its really appeasing to your eyes..there was a canteen in there .we had some snacks and pushed off to Perur temple, kovai kuttralam falls.it was not all water but we enjoyed the falls with some local tastes of masala raw mango and pineapples..we went to the famous Mardhamalai temple(Subramanya Swamy) in coimbatore.

After a night jouney from Coimbatore to Trivandrum, we boarded an AMBASSADOR to Kanyakumari. Not seen an ambassador for a long time and it is not used for taxis in Bangalore,Hyderabad or Mumbai. Every city has its own differences. An old person negotiated the rate and after that assigned to our driver.The distance is less than 90 kms but took us more than 2.5 hours because of the small towns and their traffic all across the way. Lot of banana fields is a common sight. Did not know when we have crossed Kerala and come to TN. Many buses had KSRTC board on them. At a first thought got confused with Karnataka Road Transport, but later realised that Kerala Road Transport is also KSRTC.

Sunset and sunrise is the main attraction in Kanyakumari. Kanyakumari is also in the southern most tip of the country.Also merger of 3 seas, and all the hotels are marketed using the same theme. It is very funny to see the merger of the 3 seas because it appears it is just the names we have given but no difference in the waters. Only tiffins are available in the night times in most hotels. What if we miss the sunrise is one common fears. The wake phone up is usually given by hotel management to allieviate this fear. Also a siren rings just 3 minutes before sunrise for the entire town to listen. However if it is a cloudy day, then nothing can help. We had a good view of sunrise and sunset from the sea. The moon rise on a full moon day is also a good sight as the sea that can be seen beautifully from the moon rays. A nearby temple, suchindran temple is a very distinct temple. A statue with 3 heads one of brahma,vishnu and shiva each. Wenever heard of it earlier. Also a laughing subramaniay swamy. A very old and big temple. On the way back, we had booked Jesus taxi. Kerala is truly a land of hundreds of churches. There is one in almost every street and some of them are built very differently and looked great.

Padmanabhapuram palace is a very old and huge house that is currently in TN and being maintained by Kerala government. It will surely take one away back by more than 200 years.
A scenic bridge and waterfalls on the way were also very good.

Trivandrun also has backwaters and it has been developed since 6-7 years. Usually when we hear backwaters we are reminded on Aleppey but it was surprising to know . We had a great time in the boat navigating through, lake, river and then sea. A beautiful view of thousands of coconut plantations across the border and the sea on the other side, is a sight that will be stored photographically into our memories. Later we had a visit to Kovalam beach. Filled with people, few things noticed were the restrooms were called chainGING rooms and the toilets had a note which read, Keep silence. Sayana Vishnu was the last temple residing in the Trivandrum city is one of the last places we had seen that day. Very old and beautiful temple it was. Finally night stay at Bed n Breakfast hotel beside Trivandrum airport and back to Bangalore next morning ended the memorable trip.

JMS Performance Test Tool Evaluation

An experiment

Introduction

Performance testing primarily involves 3 tasks.

1. Drive the load

2. Monitor the metrics when the load is hitting the server.

3. Analyze the results and present the observations.

A small experiment has been done to see which tool would be good to be used for testing a JMS Product. This document should not be treated as a comprehensive analysis of all the features the tools support but will only summarize the efforts made, to make a simple set of JMS features working through each of the tools under test. JMeter, Grinder, LoadRunner are the tools that have been considered for the experiment. Below is presented a summary of the efforts made for that purpose.

Environment

As a first step, Java MQ server has been installed.

All the performance testing tools required an LDAP server to be setup to run the tests

They looked for the LDAP server to build the InitialContext. It is for that purpose OpenDS has been chosen for doing the evaluation.

JConsole has been used to monitor the broker. The support provided in the testing tool can also be used to measure metrics like response times and CPU utilization. However it is to note that response times will include latencies that are brought in by the network connectivity and the number of hops.

Objective

Develop a test case to send/receive to/from a queue.

Develop a test case to publish/subscribe to/from a topic.

And

Evaluate the product in terms of the following parameters

· Configurable Tool

· Multithreading Support (Create Multiple Pub/Sub Queue/Topic)

· Data generating mechanism

· Ease of Use

· Java/JMS version support

· Reporting

Approach

Imqadmin, the default tool provided by Sun JMS has been used and the following objects have been added.

An object store has been added with the following properties

java.naming.provider.url ldap://localhost:389

java.naming.factory.initial com.sun.jndi.ldap.LdapCtxFactory

java.naming.security.principal cn=Directory Manager

java.naming.security.credentials admin

java.naming.security.authentication simple

Created a queue connection factory QCF and a Queue Q1

Created a topic connection factory TCF and a Topic T1

After that, sample clients programs have been written using each of the testing tools to drive load to hit the JMS server.

Observations

1. Each tool provides support for performance testing a JMS product in a different way.

JMeter has a UI based JMS configuration tool for Queues and Topics separately.

No coding is required for doing the basic tasks.

They may be a necessity for tweaking the tool a bit for achieving what is desired for test.

Grinder

Test Script is configurable and needs Jython scripting knowledge.
Basic examples of queues compile and run ok.

LoadRunner

A java virtual user protocol has to be used to write the test client.

· Basic examples of queues compile and run ok.

· Will require java licenses to run the scripts in the controller.

· Provides very good analysis reports, and the ability to easily put transactions.

Soniq Test Harness

Though this test harness is being told as generic for any JMS product, it requires more effort than expected in terms of setting up the properties and changing stuff related to the Sun product. On top of that it does not provide very good analysis features and lacks features that a performance test tool would have. It can be considered as a framework rather than a tool and hence it has been removed out of the scope for analysis of the tools.

2. None of the tools can be used out-of the-box.

JMeter

Found issues with the FixedQueueExecutor during multi-threading testing.

ERROR - jmeter.protocol.jms.sampler.FixedQueueExecutor: Correlation id is null. Set the JMSCorrelationID header

The message fields cannot be set without tweaking the java files and recompiling JMeter.

Grinder

Topic tests fail with compilation error. NO MODULE NAMED THREADING (threading.py). Need more tweaking to be done to the test scripts to get it working.

LoadRunner

Found issues with the topic examples. They compile fine but do not hit the server. Tool reports that messages have been sent but JConsole does not show that the messages are consumed by the broker.

3. Tool Evaluation

Points 1-5 are given against each of the attributes

happy independence day

2009-08-15T00:47:00.001-07:00

Celebrating Independence day in India after 3 years...
Watching auto drivers putting huge India flags and driving ...
and creating a sense of the same feeling among all those who see the flag,
that we belong to that one same thing.

What a feeling...words cannot describe.

Art of Performance Testing.

2009-07-29T23:05:00.001-07:00

Performance tuning is a challenging task that requires in-depth understanding of the hardware, operating system, and application. If performance tuning were simple, the parameters would be hard-coded into the firmware or the operating system.

Art of Application Performance Testing

When is an application considered to be performing well?
It is a matter of perception and usage scenario.

A "Performance Driven Organization" is that whose performance considerations have been taken into account at every stage of the application life cycle.

Tool should provide single view of monitoring various mertics across servers.

Frequency of collection of metric and display of collection.
CPU count
per CPU stats or aggregate stats
Number of Queues waiting for CPU
Time spent waiting for a CPU
Swapped out threads
User, System utilization and Ilde time of the cpu
Load average
Migration of threads between processors
Mutex contention events on kernel.
read/write lock contention events on kernel.
system call rate
Which process/thread/method is using the CPU

perf- CPU- Solaris

2009-07-23T19:47:00.001-07:00

CPU

The first line of metric is the summary since boot.Interval of collection is specified as 1st param along with command name.

vmstat collects the aggregate stats of all the CPU's

Saturation

Number of queues waiting for CPU is run queue length or size.
kthr:r of vmstat gives this value.
sar -q 5 5 gives info on swapped out threads. It also gives runq-sz. Swapping out threads is a last resort for relieving memory pressure, so this field will be 0 unless there was memory shortage.
Amount of time spent waiting for a CPU is measured using the LAT latency value of command prstat -mL

vmstat and sar(system activity reporter) also give the user,system utilization and ilde time of the cpu.

Number of processors in the system and their speed psrinfo -vm

Load average represents both CPU utilization and saturation.
uptime and prstat give this info. A value equal to CPU count means 100% utilisation.
1-,5- and 15- minute averages are obtained.

sar can capture historic data by enabling interval of collection. crontab -e sys

mpstat summarizes stats for each cpu.

High values of

migr migration of threads between processors
smtx mutex contention events on kernel.
srw read/write lock contention events on kernel.
syscl system call rate

is bad for performance.

Who is using the CPU
prstat gives pid versus cpu utilisation%
prstat -Lm -p pid, gives thread breakdown of pid.
To see what the thread is doing, use pstack pid/processor no, ex: pstack 25691/2

use dtrace to find out who is causing the high system calls.
dtrace -n 'syscall:::entry { @[execname]=count();}'
use dtraceto drill deeper and find the exec name
dtrace -n 'syscall:::entry /execname=="name_of_exec"/ { @[probefunc]=count();}'
use dtrace to drill even deeper to get the stack calls.
dtrace -n 'syscall:::entry /execname=="name_of_exec"/ { @[ustack]=count();}'

Java Performance Tuning - contd.

2009-07-22T00:15:00.001-07:00

Two standard optimization techniques for reducing I/O overhead are buffering and caching.

Some techniques to improve I/O performance:
Execute I/O in the background.
Avoid executing I/O in loops.

Using System.outor System.err, for logging,purposes can affect performance.
Using any logging framework like log4j, can allieviate this to some extent.
Check Readers are InputStreams performance. Readers may be better.

Use a separate thread to monitor the application.
multithreading issues- race conditions and deadlocks.

Performance tuning is frequently a matter of tradeoffs.

Tuning can be a lengthy process simply because it must be iterative.
Performance problem created (or left uncorrected) in one phase requires roughly five times as much effort to correct in the following development phase.

Performance tuning should be done after the code is functionally correct.
Typically, 80% of the application time is spent in less than 20% of the code.

When designing the application to run activities in parallel, you need to focus on shared resources,especially the time spent using these resources.

Identifying that there is an I/O problem is usually fairly easy. The most basic symptom is that things take longer than expected, while at the same time the CPU is not at all heavily worked.The diskmonitoring utilities will also tell you that there is a lot of work being done to the disks.

Vendor Supplied disk statistics.
average and peak transfer rates
Average seek time,

Cached Filesystems (RAM Disks, tmpfs, cachefs) speeds up reads.
Looking up network addresses is an often overlooked cause of bad network performance.

Lock contention is one of the major reasons for performance problems. There are four types of locking available in Solaris. 1. Mutexes 2. Semaphores 3. Condition Variables and 4. Multiple Readers Single Writer(read-write) locks.

Java Performance tuning-contd..

2009-07-17T05:25:00.001-07:00

One can choose a JDK version(vendor) for compilation and another JRE version(vendor) for execution.

Understand the GC pattern of the application.Adjust GC interval and -Xmx if it helps, after looking at the pattern. Use trial and error to set this values.

Casting is an overhead. If all the list objects are one type, they better be declared as a collection of that type.Casts(not resolvable at compile time-using instanceof operator) have runtime memory cost.

Is the development VM same as the production VM?

JIT compiler, compiles bytecode into machine native code on first execution.
Bytecode interpretor executes by decoding,converting into native code and then executing.
Shared libraries can be loaded into system memory even before application startup to application reduce startup time.

Some compilers have the optimise option (-O) meant to compile such that execution optimisations can be applied.
You could compile to native machine code directly.
-J and -target options exist during compilation.
Running application with -verbose option give insight into the loading..etc.
Translators exist that convert Java program to C.
Class loading times improve if jar packaged.

adaptive optimisation

Optimizing compilers cannot change your code to use a better algorithm.
Ask/Decompile to know what the application is doing under the hoot. Don't assume.

Class.forName dynamically loads libraries and can be time consuming.
compilers compute runtime code path tree.

Code motion moves calculations out of loops that need calculating only once.
Obfuscation makes code tough to understand after decompiling and has also can have performance gains.

Check the application startup parameters.

Java does not prevent you from using excessive amounts of memory.

Check object creation and know why they are being created.
Container object can be pool managed by custom defined classes. Ex:VectorPoolManager

Early initialization involves creating objects before they are used and is used when large number of objects are needed. Late initialization involves delaying object creation till it is absolutely necessary thereby avoiding unnecessary object creation.

Throwing an exception and executing the catch block has a significant overhead. This overhead
seems to be due mainly to the cost of getting a snapshot of the stack when the exception is created (the snapshot allows the stack trace to be printed). The cost is large: exceptions should not be thrown as part of the normal code path of your application unless you have factored it in.

Local (temporary) variables and method-argument variables are the fastest variables to access and
update.

Instance and static variables can be up to an order of magnitude slower to operate on when
compared to method arguments and local variables.

ints are normally the fastest variable type to operate on. longs and doubles can take longer to
access and update than other variables because they are twice the basic storage length for Java
(which is four bytes).The specification allows the actual manipulation of longs and doubles to be
implementation- and processor-dependent, so you cannot assume longs and doubles always take
longer.

Java Performance Tuning 2nd edition - Jack Shirazi

2009-07-16T05:27:00.001-07:00

Identification of the cause of the performance bottleneck is a science, not an art.

Measure/Profile current system in terms of

   Response time/TPS
   Memory
   Disk I/O
   CPU
   Concurrency

per layer and end to end for transactions identified by business in the descending order of risk or target volume per unit interval

Freeze them so that they can be served as reference at any point of time. This version of the software at any time should be installable to demostrate the effect of the changes made later.

Get to know the benchmark figures of performance of the software/hardware platform from industry.
What are the SLA the application has to conform to? Define them if they do not exist already and strive to achieve them. Agreeing on targets before tuning makes everything clear to everyone.

Follow a top-down approach, come up with observations and take direction from management on proceeding with the next set of efforts. Document all such decisions. Suggest not based on gut-feel but based on repeatable results of experimental evidence. Communication of your effort daily to management and taking their suggestions frequently is vital, as performance testing/tuning is an incremental R&D activity and some times lot of effort may go in the wrong direction or may require more time to get a solution. Always keep track of the problem perceived by management about the application and try to allieviate it.

Understand the cause
Hypothesize a solution
Test Hypothesis.

The trouble with doing something right the first time is that nobody appreciates how difficult it was.

There is a VM overhead for Java programs.
Slow and Fast are relative. Don't use relative terms, talk in terms of metrics.

JDK 1.3 introduced a new java.awt.Robot class, which provides for generating native system-input events, primarily to support automated testing of Java GUIs.

Sequential or Parallel.

The application has to be limited by something, or it would take no time at all to run.Solving one issue uncovers others. This process goes deeper. Finally the optimum performance is achieved on a hardware.

Product performance testing involves benchmarking on different hardwares.
Projects are usually confined to one set of hardware,software.
Cost/Time/Effort involved in making the changes suggested have to be mentioned while making recommendations.

Automate the process of testing and graphing, so that it can be repeated after applying fixes easily. Ability to compare across the test runs, after tuning is useful.

Identify if tuning is transaction, parameter, or concurrency dependant.

Perceived Performance
When the test is on, run a manual user to check user perception.
If you give users an expectancy of how long a particular task might take and why, they often accept that this is as long as it has to take and adjust their expectations.
Sometimes the users bandwidth might be the cause of slowness perceived.
Do not give users momentary false expectation that download is complete when it has not in reality but only a component has been.
Give the user a choice to decide between better performance or functionality.
Is the UI responsive?
Does UI allow user to cancel any task perceived as long by user?

Do Threading,Streaming,Caching to appear faster.

Every atomic change has to be measured distinctively. Do not make more than 1 change at a time before retesting and document all changes.

If it ain't broke,don't fix it.

Is the priority of the process changing with time.
Know the options of netstat,iostat,vmstat,sar,top,ps,snoop,ndd,tcpdump,ethereal,sysstat,mpstat

Starting app with -verbosegc option gives app's GC stats.
JDK comes with minimal profiler which can be enabled by Xrunhprof:file=<filename>
Method profiling can be done by java -Xrunhprof:cpu=samples,thread=y <classname>
jhat included in JDK is Java Heap Analysis Tool.

The JDK provides two methods for monitoring the amount of memory used by the runtime system.
The methods are freeMemory( ) and totalMemory( ) in the java.lang.Runtime class.

Between client/server communications, the number of transfers and the amount of data transferred,and bandwidth limit performance.

If RMI is used for communication, -Djava.rmi.server.logCalls=true <ServerClass> can be used to log the calls. A program can be written to intercept the socket communication that will serve as passthrough, as FedEx reliability team has done.

How to Sell Anything to Anybody

2009-07-09T20:50:00.001-07:00

Salesmen are made,not born.- Joe Girard.

Joe in his 15 year selling career sold 13001 cars.
Time,Money,Effort,Passion,Responsibility
When a salesman sells, there are no losers. Both the buyer and the seller win.
The process that leads to victory should start long before you ever see your prospect and goes on after the customer signs and leaves with his purchase.
ATANA->All Talk And No Action
Understand whom you are dealing with and what they really want to hear.
Its no fun being turned down. But i soon found out that the more people i talked to, the more sales i made.
Broom, thats the word we used for getting fired.
About Land. In my youth, i did'nt know that you're supposed to believe anything unless you see it in writing.
Recapitulating about, what i was trying to say,what i should say and what the listener wants to hear helps know and improve myself.
Know what you want.
Some customers are interested but scared of the sales person.
Attitude matters.
Know who is your prospect, and position your prospect in the money pyramid. Every time you turn off one prospect, you turn off 250 more.
Don't join the club in whatever company you work.
What counts is how you work, not where you work.
How smart i work is even more important than how hard i work.
Even a small effort in the right direction matters.
CONTACTS=traffic.
Give your cards, more importantly take theirs.
If you throw enough sphagetti on the wall, atleast some of it will stick.
The people you buy from certainly ought to be in your prospect list.
Make sure everyone knows what you sell.
Thikn about others. Give more than they expect.
Online Customer info that helps to know IP,username,referred_from,user_agent,date_time_visited,page_visited,last_visited,number_of_visits,next_page
Subject line in a mail is important as that decides/motivates the reader to go further.
Send different color and shape on envelope and never put your name outside the envelope.
Gift customers stuff like calendars, keychains, cups, daily used things with your company name tag on it.
Watch the way in which giant companies spend millions just to keep their name in front of public.
Build your own prospect list, do not buy it from organisations.
Keep your promise.
Everybody can be your birddogs. Keep birddogs and pay them commissions.
Identify professions that deal with many people and their networks.
ASK ME ABOUT THE BEST CAR DEAL IN TOWN, i offer that sign to the barber, explain my $50 payment and leave him a stack of my cards.
I have an agreement with the dealer to the effect that if somebody is really important for us to sell at a loss, i can do it if i get permission first and make up out of my own pocket anything less than dealer cost that i want to wsell the car for.
A birddog who will brag about the deal he got and tout me and my dealer all over.
Plan your work and work your plan.
Get more people coming through the door, get more traffic.
replay the day.
Honesty is a matter of degree. It is never all one way or the other.
The salesman should look as much as possible like the people to whom he wants to sell.
Get them obligated to you.
A lot of times a customer will tell everything you need to sell them. Listen and think.
The customer often really does not know what he can handle and what he should buy.
Unless he asks me,i'm not going to talk about my family. This is not a social situation. This is selling and i believe that one of the dumbest things to do is compete with a customer.
Let him have the stage. Just sit there and look.
read body language
know how much shopping he has already done.
dont ask him a question that he can answer yes or (especially) no.
Get answers by asking questions and giving optins to figure out what the prospect wants.
I get up and almost turn my back on the customer, very straight out, i half turn , put out my hand, a say, "Give me $100 and i'll have them get the car ready for you.
I'll take a check.
I'll look him in the eye and say, You dont need any money. Your word is good enough for me.
A rabbit in hand is better than 2 in the bush.
The way you take care of customers who have problems matters a lot.
Keep in touch and ensure that the customer is happy.
i sell more than 6 cars everyday.
nobody sells all alone. To sell customers you use help, whether you think of it that way or not. You use the telephone.
What i do today, i want to beat tomorrow.
selling is acting.
i could probably raise the money to become a dealer and i could probably run a pretty good operation. But i dont want to. I am having a good time selling.
Look for new and different way to approach the same old problems.dont be afraid to do it differently. it's usually better.
The process of successful selling means the endless use of your mental resources.
Just O.K this for me, instead of signature.
Want it bad enough to make it affect your professional life.
There was no way to survive if i kept believing that i was no good.
Everybody who makes himself into something better has to fight the forces in him that want to be something worse.

Rich Dad, Poor Dad by Robert Kiyosaki

2009-07-09T07:55:00.001-07:00

Richness is not about money. It is about the thought.
Be aware of everything around you.
You must know the difference between an asset and a liability.
Dont work for money, let money work for you.
Be smart and you wont be pushed around as much.
We learn by making mistakes. While learning to walk, we fall down also.
Education is more valuable than money,in the long run.
Life is like going to the gym. The most difficult part is deciding to go.
The more specialised you become, the more trapped and dependant on that speciality.
Know a little about everything, and everything about a little.
To be truly rich, we need to be able to give as well as recieve.
One of the wonders of the world is the power of compounding interest.
Whats your investment portfolio?
The human spirit is very powerful. It can do anything.
Invest first in the education of investing.
Dont listen to poor or frightened people.
Self-Discipline is needed and without it, everything earned is lost in a second.

Dollar Bahu

2009-07-05T23:20:00.001-07:00

Last week i've been to landmark book shop and while browsing through the
books,saw this one written by Sudha Murthy
(http://en.wikipedia.org/wiki/Sudha_Murthy).As i have never read any of
her books and the title "Dollar Bahu" seemed interesting, have taken
this book.

She handles relations of various characters very
softly in this book. The potray of sensitivity in the relationship
between Chandru (the dollar guy) and Vinutha (the poor lady from
Dharwad village) on whom Chandru has a crush and who later becomes his
brother's wife is very good. The same can also be seen when
Shamanna(the father-in-law) of Vinutha, suggests that Girish(Vinutha's
husband) and she move back to Dharwad to lead an independent life away
from the day-to-day comparisons that will be brought about by
Gowramma(mother-in-law) who will be back from the US.

There are few references to the bakula flower here. There is another book she wrote called bakula flower.

The
frustration about Vinutha about the dollar and her prayer to God, Let a
day come when forty five dollars are equal to one rupee, is quite a
different and radical view.

The final part where Shamanna advices Vinutha about India and US is good.

There
is nothing absolute in life. America has a set of advantages and
disadvantages. Similarly India has its own. You cannot have the best of
both worlds. If you have a choice, choose a country and accept it with
its pluses and minuses and live happily there. Staying in America and
dreaming of an Indian way of life,or living in India and expecting an
American way of life-both are roads to grief.

You are the best.

Web automation

2009-06-16T23:11:00.001-07:00

Number of web automation tools used to record and replay user actions exist as FireFox Plugins.
Examples: Sahi, IBM CoScripter, Selenium, TestGen4Web, ChickenFoot, etc..

They have not become immensely popular or useful though they are used by niche testers or users. The reason for that could be, some of the features missing in these tools that provide "value points" such as , inability to schedule automated executions, inability to compare a value on a page to the expected result using XPath or any such mechanism, having a lack of notification mechanism for alerting users when the value points have been found and inability to serve a mobile customer.

In order to alleviate such issues, server side replay engines can be created and used.
using technologies like Server side java script document manipulator like Rhino + Google AppEngine.

While most of the user defined automated scripts in the above examples are spam, it is necessary to develop admin controlled and useful automation requests whose definitions can be taken from people manually through a website.

Site Stickiness of a Page

2009-06-16T00:50:00.001-07:00

Every web page has links. Some links point within the site and some links are external.
The ratio of internal:total links in a page, is a measure that can tell the probability of the user to stick, to the site or to go to another site. Let us call this as site stickiness of a page.

Site Stickiness=(internal links/total links{internal+external})*100

This is the probable percentage that a user will stick to your site.
Inorder to get this measure, use the following javascript code.

var intern=0,extern=0;
for(i=0;i<document.links.length;i++){

if(!(document.links[i].href.toString()).match(document.location.toString().split('/')[2])){
extern++;
}else{
intern++;
}
}

var sticky=((intern/(intern+extern))*100);
console.log(sticky);
alert(sticky);

Customer defined alerts

2009-06-09T06:22:00.001-07:00

Server defined alerts are good to startup, but the developer will get worn out trying to satisfy all of the customers. So the other option is to have customer defined alerts.

So, giving choice to user to define alerts for common web workflows she/he is interested in, is a feature, that has to be implemented in Informer.

For doing so, a record/replay engine has to be developed.

The architechtures which are applicable for coding such a thing are

1. Develop plugins like selenium/testgen4web does that are browser specific. In this case, we have to cater to FF,IE,Safari,Chrome, Opera.

2. Allow the browser to go through a local proxy which intercepts the requests. For this , user has to make changes to his network connectivity profile in the browser, which might not be a good thing to ask the user to do.

3. Develop componets using the RIA web client frameworks like Titanium, Adobe Air, Mozilla Prism, Java FX, Fluid...

Titanium through open is very new and it is better to go for it after 1.0 release as it crashes on me even during installation.

Adobe Air might be a good choice for the time being. As each of the framworks uses javascript, it is good. We can interchange later , if needed.

Different things...

2009-06-09T06:06:00.001-07:00

Recently i have done many things that are different and that i have never done in life so far.
Some of them were considered bad and many people are addicted to them and so, those addicted do not feel it is bad, but those who are not, feel so.
Some of the things are done by people on special occassions, good and bad.
Some of the things are considered taboo, by some specific sect of the community.
Some of the things are done by people, most of the times but only secretively.

There is no reason for doing them.
The need to do something different was the motivating cause.

While, doing most of these things it is quite easy and possible through money, there is no significant effort required for doing them. After doing all of above things there is a loss perceived.

After trying all these things, now i am getting motivated to do things that are different and difficult to do and which will give profits.They not only require commitment but also a constant sense of purpose for achieving the goal set against to achieve. Let me see what hurdles will come in the process and what has to be done to overcome them and get to the goal.

Informer-Business Plan

2009-06-05T05:52:00.001-07:00

Business plan for Informer

The only place where success comes before work is in the dictionary.

Company Name: Informer

Sector : PC / Mobile Internet (Software as a Service)

Business Overview:

Actions such as receiving a phone call or SMS, GRAB THE Customer’s ATTENTION to the device. Internet on a mobile phone is primarily, user initiated. As smart phones and net-books reach the masses, the need for delivering value, to a mobile customer and getting customer's attention, is more useful, than a pull based internet. A push based model guarantees such a possibility. The need for benefiting from internet, as a push based model, is the idea of creating the product "Informer".

Market opportunity:

Addressable Market size:

Android has a first year market size of 125,000,000 users
100 million European T-Mobile users will be offered the G1.

May target software for additional platforms like IPhone, Blackberry, JavaME, WinMo based smart phones after success with android, thereby increasing the target market size by leaps and bounds.

Reference: http://www.texasstartupblog.com/2009/01/01/android-in-2009/

Rev potential: Depends on which model will be adopted.

May use on any of the following models for revenue generation

Advertisements
Publisher Content
Customer Plug-ins

Business Model and Business Development:

Internet is dynamic. New content gets added to it all the time. Internet is vast and the cloud keeps on growing in size. The amount of information that a user will be interested is a small subset of internet. User can define it, at any moment.

(1) It can be personalized like

Twitter updates
Orkut scraps
Calendar events
Jobs for your profile

(2) OR it can be location based like

Shopping deals in a city.
News of a country.
Weather of a region.

(3) OR it can be time based like

Price of a stocks in my portfolio at this moment
Status of my hosted application now

"Is there any latest information available on points (1), (2) and (3) on the internet?” is a question, if answered, will SAVE the customer a lot of TIME. Most of the times, the user is actually concerned with a specific state of the information, rather than the information itself and this is called a "value point",

Example

Is the price of a stock above/below a value?
Is my application down?
Has a "user defined webpage", been updated?

This is where, Informer comes into play. It regularly checks for a user specified “value point”. If met, user may want to take further action. Sometimes user may just want to get notified, so that he can take further action manually. For example, user might read a particular webpage/blog entry and wish to read it again in the future when a new entry is posted or the page is updated. For this purpose, earlier the user used to add the page to his favorites, and check for updates manually, periodically. With Informer, the user defines the page URL and lets Informer worry about the “check for updates” task and gets notified by Informer whenever that page gets updated. Informer also makes its user to be the FIRST TO KNOW, about any event compared to the non-users of this tool. To meet the above requirements, Informer contains a set of plug-ins that defines functionality as stated above. A plug-in also contains some initial configuration to setup. Example: User may enter stock symbols and give a value above/below which notification is required. The user adds the plug-ins of interest to her/his profile. Apart from that it contains a core processing engine and UI specifically intended to define the tasks to be automated. Interfaces that Informer intends to support are for Web and Mobile users.

(4) If the customer needs some "value points" that are quite different from normal, and niche, then specific plug-ins to meet that need can be developed.
