FDI in Retail

Neighbourhood stores provides me these many options, if I want to buy Rice, Gehun. 

While If I go to Reliance store, I have only one option to choose. And lots of packaged variety of Basmati rice. 

Can I see same picture in Future? Will they be able to Survive with Multi-brand retail.

Only Time will tell. 

Computing In the Cloud!

Recently I was invited as a guest speaker at International Educational Conference held in Pune, India. Here are presentation slides of my talk.

Installing Mosquitto & LibMosquitto for python on Mac OSX 10.8 (Mountain LIon)

Its quite easy, though not many online posts are available. Mosquitto site doesnt give much information apart from suggestion to install it using brew.

First Install Mosquitto using brew
$brew install Mosquitto
it may fail due to wrong perms on /usr/local so change ownership of local dir

$sudo pip install Mosquitto 
To Use Mosquitto from Python

It may give following error
Traceback (most recent call last):
  File "/usr/local/bin/pip", line 5, in
    from pkg_resources import load_entry_point
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 2603, in
    working_set.require(__requires__)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 666, in require
    needed = self.resolve(parse_requirements(requirements))

You need to upgrade Pip as you are using old pip
$sudo easy_install -U pip
and try again

$pip install mosquitto

It works. Confirm it.

$pydoc mosquitto

Twitter - Mega Network with Micro Updates.

I did analysis of Twitter usage by Common people and Enterprises. This is How twitter started and grown in to Mega Network with Micro Updates.
1) Tech people were early adopters
2) People used it as a replacement for blogger where they need to give a lots of time for posting anything. Twitter was easy,no-brainer, one can tweet whatever they have on their mind. They dont have to ruminate over it.
3) People loved it.
4) Additionally it enabled open conversation across the globe. Just simple stream of interesting thoughts, updates abt various people by themselves, you didnt need approval to follow him/her. 
5) It enabled way to hear thoughts of people who shares common interests with you.
6) It was not like other social networks where you start with connecting people you are already friends with.
7) Everybody actually liked the Idea, even Celebrities came directly on twitter. Interacting with their fans openly. People loved this more.  With Celebrities, more fans logged on Twitter. For Example, many of the people in India registered on Twitter to Follow Little Master Sachin Tendulkar. 

With Millions of real people having open conversation on Twitter and additional features built like Trends. For Marketers, It was gold-mine to catch the people. Specific targetting was possible just scanning through one's tweets. Lots of startups have emerged which are providing various services  including analytics of data and techniques to increase follower counts.
From My point of view, we can clearly seperate companies in 2 types
Type B2C = Business to consumers Model
Type B2B = Business to Business Model

For B2C Enterprises, value proposition is quite clear as many of their existing and target customers possibly would be on Twitter. They can use Twitter for Customer Service, Marketing and Advertizing. They can run Loyalty programs also.

But what would be value proposition for Enterprise who has B2B model, because they would be trying to sell their products to companies only. so How Twitter can be useful for B2B model companies. Because Twitter accounts of these companies would be handled probably by Marketing Team. If Twitter accounts of 2 businesses converse with each other, which means basically Marketing teams of 2 companies are talking with each other. Which will not help one of them who wants to sell his product to other.  As other's marketing team might not be decision makers in various purchase decisions or business decisions. 
Although Conversation may not help either of them to get business. but connecting with people who are following/followers of target company may help. 
What enterprises can use Twitter for?
1) Share/Evangelize knowledge abt their company, product.
2) Connect with people who are connected to your targets.
3) Spread the word abt your company in related open conversations.

Actually I am not a Marketing guy but had some thoughts abt using Twitter by Enterprises so just shared them here.  You can have many other great ideas abt Twitter usage, You can share it with me via comments on this blog.

Rachleff's Law of Startup Success

The #1 company-killer is lack of market.

Andy puts it this way:

• When a great team meets a lousy market, market wins.
• When a lousy team meets a great market, market wins.
• When a great team meets a great market, something special happens.

You can obviously screw up a great market -- and that has been done, and not infrequently -- but assuming the team is baseline competent and the product is fundamentally acceptable, a great market will tend to equal success and a poor market will tend to equal failure. 

Market matters most.

CodeIgniter - Upgrade from 1.7.x to 2.x.x - Session Reset issue

Hi you can follow instructions given at below link

Upgrade to 2.x.x


You will get stuck at session issue as session gets reset after you redirect. Redirects might be required in authentication flows.

You will face this issue particularly when you use database table "ci_sessions" to store session information.

CI upgrade have changed ci_sessions table structure in 2.x.x.

CodeIgniter - Sessions - Documentation


CREATE TABLE IF NOT EXISTS  `ci_sessions` (
session_id varchar(40) DEFAULT '0' NOT NULL,
ip_address varchar(16) DEFAULT '0' NOT NULL,
user_agent varchar(120) NOT NULL,
last_activity int(10) unsigned DEFAULT 0 NOT NULL,
user_data text NOT NULL,
PRIMARY KEY (session_id),
KEY `last_activity_idx` (`last_activity`)
);


in previous version user_data size of varchar(50), this causes session data being stored partially, and not able to retrieve it afterwords.


You just need to backup previous session table and create new ci_sessions table with above script.

Game of Real Estate - Rental Market Tricks

Since last 2 years fortunately or unfortunately, I spent lots of time in searching and hiring rental flats/office space. It was specifically in Mumbai and Pune.  I also stayed in Hyderabad in 2004-06, at that time there were not need of agents as rents were pretty low, we used to pay 4k for 2bhk+waiting room  and normally House owners use to put up boards on building itself telling about rent.

In early 2006, I had to search for home in Vashi, Mumbai. Scene at that time was, builders relative was looking after that building so it was difficult bypass  him but rent was just 6k for 2 bhk so again It was not issue paying brokerage.

But after 5 years in 2011-2012, picture is pretty different, rents are skyrocketed everywhere.
In Mumbai, In area like gorai and anand nagar in Dahisar, every building has a office of agent.
Single flat is shown by multiple brokers :)

Brokerage business is at its prime, Many of brokers own cars in Pune, instead of bikes as they used to.
And they demand 2 months rent as brokerage. Trick behind this is normally 3-4 brokers are involved with 1 flat so every one of them need to get respectable share of income. so they normally dont negotiate on brokerage.

Here are some of quirkiness of brokers and dont believe them

1) Even if there are lots of properties available, broker will first tell you that there are almost no flats are available or they will give you options of just 2-3 flats.

2) If you went to broker well in advance for say 2 months, He will not at all cooperate with you, as you are not needy, he cant play games with you as you are at comfort.

3) If you are looking space for Office, Owners and Brokers will tell you that Office is very lucky for previous owners and whoever rents this space, grows with no Limit.

4) There is always space for negotiations with broker, Its easy to convince broker than Owner as for broker its onetime income while for owner its yearly income.

5) If you like some flat or space, Owners will tell you that there is one more party interested in said flat/space and some will add a punch that other party is offering more. also he will tell you that they want good people. This is trick to stop you from negotiations.

6) Specially in Pune, Many flat owners are Mumbai investors, They try to play game with Mumbai Rules, so dont get into their talks.. for example they will ask you high rent and 6 months rent as a deposit, which is normal in Mumbai but Pune rules are different. its 2-3 months of rent as deposit

7) Trick is to Fix your Budget for rent and tell Broker budget 10% lower. Contact multiple brokers, make sure that they are not connected to each other.

8) Most important is Dont Giveup and Commit early on deciding on some flat/office space, always borrow some time from owner to think whether it is satisfying most of your requirements like locality, rent, transportation, water, electricity, internet.


9) Following sites are good for Getting flat ads directly from owners:
    a) Quikr
    b) Sulekha
    c) Magic Bricks
    d) Anand Property listing (very good)
    e) Olx


Happy Searching and All the best.

How to calculate Marketing Budget - Grabowski Ratio

Some one asked a interesting question about calculating Marketing budget.
Whether you are Startups or established Big Company, Marketing is important aspect of business.
It is  qualititive, not quantitive. We can not easily measure the effects of Marketing and budget.

I hit this document through quora and found it quite interesting.

http://www.slideshare.net/dmitryklimov/ralph-grabowski-fullarticle


here is summary, which I understood,
a) Invest more in Marketing (exclusive of Promotional and selling) than in Engineering
b) At Early stage of Product development, One should allot budget in ratio of 1:1 for Market Research and Engineering.
c) Low ratio will lead to failure
d) How much is More Marketing?
     Marketing is defined as a upfront process that comes before the product is ready. (Promotion and selling comes after product is ready)
e) More Marketing is qantified into recommendation that technology based enterprises invest more than one dollar in marketing for each dollar invested in engineering

f) Marketing/Engineering Investment ratio > 1
