India's unknown facts
Interesting Facts On India That You Had No Idea About
Proud to be an Indian
India is, the cradle of the human race, the birthplace of human speech, the
mother of history, the grandmother of legend, and the great grandmother of
tradition. Our most valuable and most instructive materials in the history of man
are treasured up in India only."
These are not our words. These are the words of the great Mark Twain. And here
are Indians facts to support his statement:
1. A floating post office
India has the largest postal network in the world with over 1, 55,015 post offices.
A single post office on an average serves a population of 7,175 people. The
floating post office in Dal Lake, Srinagar, was inaugurated in August 2011.
2. Kumbh Mela gathering visible from space
The 2011 Kumbh Mela was the largest gathering of people with over 75 million
pilgrims. The gathering was so huge that the crowd was visible from space.
3. The wettest inhabited place in the world
Mawsynram, a village on the Khasi Hills, Meghalaya, receives the highest
recorded average rainfall in the world. Cherrapunji, also a part of Meghalaya,
holds the record for the most rainfall in the calendar year of 1861.

Cloud Computing Basics
What is Cloud
Computing?
•Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers,
storage, applications, and services) [Mell_2009], [Berkely_2009].
•It can be rapidly provisioned and released with minimal management effort.•It provides high level abstraction of computation and storage model.•It has some essential characteristics, service models, and deployment
models.
Essential
Characteristics:
•On-Demand Self Service:
•A consumer can
unilaterally provision computing capabilities, automatically without
requiring human interaction with each service’s provider.
•Heterogeneous Access:
•Capabilities
are available over the network and accessed through standard mechanisms that
promote use by heterogeneous thin or thick client platforms.
•Resource Pooling:
•The provider’s
computing resources are pooled to serve multiple consumers using a multi-tenant model.
•Different
physical and virtual resources dynamically assigned and reassigned according to
consumer demand.
Service:
•Cloud systems automatically control and optimize resources used by leveraging a metering capability at some level of abstraction appropriate to the type of service.
•It will provide analyzable and predictable computing platform.
Service Models:
•Cloud Software
as a Service (SaaS):
•The capability
provided to the consumer is to use the provider’s applications running on a
cloud infrastructure.
•The
applications are accessible from various client devices such as a web browser
(e.g., web-based email).
•The consumer
does not manage or control the underlying cloud infrastructure including
network, servers, operating systems, storage,…
•Examples:
Caspio, Google Apps, Salesforce, Nivio, Learn.com.
•Cloud Platform as a Service (PaaS):
•The capability
provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider.
•The consumer
does not manage or control the underlying cloud infrastructure.
• Consumer has
control over the deployed applications and possibly application hosting
environment configurations.
•Examples:
Windows Azure, Google App.
•Cloud Infrastructure as a Service (IaaS):
•The capability
provided to the consumer is to provision processing, storage, networks, and
other fundamental computing resources.
• The consumer
is able to deploy and run arbitrary software, which can include operating
systems and applications.
•The consumer
does not manage or control the underlying cloud infrastructure but has control
over operating systems, storage, deployed applications, and possibly limited
control of select networking components (e.g., host firewalls).
•Examples:
Amazon EC2, GoGrid, iland, Rackspace Cloud Servers, ReliaCloud.

14 WAYS TO MAKE ANDROID PHONES MORE AWESOME
14 WAYS TO MAKE ANDROID PHONES MORE AWESOME
Your Android
phone has a lot of features baked in from the start, but what if you want
better? There are some amazing (and free) third-party replacements for the
stock features of any Android phone.
Here are some
awesome apps that we recommend to make your Android device even more awesome
than it already is.
1.
IMAGE GALLERY
The default
gallery app on most phones is good enough just for viewing images. However,
there are third party apps that offer you much more. We recommended QuickPic. It’s faster, gives you
multiple view options (stacks, grid, lists), colour themes, cloud storage
support, Wi-Fi transfer, password-locked secure folders and even built-in
editor.
You can also
look at the free Cyanogen gallery app that lets you manage
local as well as cloud-based photos and videos. It also automatically sorts
photos into smart folders using the location/date metadata.
2.
EMAIL
Usually, the
Gmail app and a separate email app are pre-loaded (and the email app only
offers basic functionality).
A great
replacement for the default app is a free app called CloudMagic. It lets you add up to 5
accounts and supports every type of email provider (Gmail, Outlook, Exchange,
iMap, iCloud, Google Apps etc). It offers a unified inbox, password lock, push
notifications, custom folder sync and lets you attach files from the cloud.
If you only
want a Gmail replacement, check out the free Mailbox app. Mailbox has its own
sorting system that lets you manage mails easily.
If you want a
better, unified email app on your phone, try myMail (by My.com BV). It’s free to use and
supports all major email providers (Gmail, Yahoo, Hotmail, Exchange, Live,
iCloud + IMAP & POP3). For simple scheduling of emails and SMS, try Message & Email Scheduler by
RCM Apps.
3.
CALENDAR
There’s not
much to complain about Google Calendar app on Android. However, if you want a
better looking app with additional features, give the free SolCalendar a try.
SolCalendar lets you sync with other
calendars you may be using (Google, Yahoo, iCloud, Exchange) and shows an
easy-to-understand month view with easily visible highlights. You can also take
a quick look at the weather, set recurring alarms, view your agenda on a
day-by-day basis as well as maintain a to-do list — all in single app.
4.
CAMERA
Every phone
maker tweaks the camera app with various features and interface. However,
Google offers its own camera app for free in the Play Store
for anyone to use.
While it has
a basic interface, it offers features like photosphere, 360-degree panoramas
and the option to capture images during video recording. There is also a useful
lens-blur feature that lets you control the depth of field in a photo (post
capture).
If you’re
looking for an app that gives you tons of effects, editing, manual controls
& filters, try Camera 360 Ultimate.
5.
NOTES
For notes, we
recommend Evernote. This free app is loaded
with features and syncs your notes across multiple devices with ease.
Not only can
you create notes in the app, you can also easily organize them into notebooks.
Notebooks can be shared (for collaboration). A great feature is the fact that
you can create different type of notes: to-do lists, expense management as well
as travel management.
You can even
add multimedia files to a note for quick reference and quickly search through
hundreds of notes. Alternatives are Google Keep and Microsoft OneNote.
6.
CONTACTS
They both
have different approaches: Addappt syncs your contact
information with others who use Addappt — any change either of you make to your
contact details is updated in other’s contacts. 6 Degrees does that and also allows
you to search for and get introduced through common contacts.
7.
DIALLER
The basic
phone dialler does nothing apart from dial numbers. The free Truedialer (by True Caller) replaces the default
contacts & dialler and lets you quickly search for numbers beyond your
phonebook because it integrates with True Caller’s online database.
You won’t
have to see unknown numbers in the call log either because the app will
automatically add info (where available).
8.
KEYBOARDS
Even if you
think the default keyboard on your Android is great, it might help to try out
something else (you might end up saving time by customizing it to your needs or
typing faster thanks to better prediction and swipe input).
Swiftkey gives you over 70 themes,
adjustable keyboard sizes and personalised predictions. Swype gets used to your
style and stays with you if you change devices. Others that are worth a shot
are Fleksy and TouchPal.
9.
FILE MANAGER
Even if you
have a basic file explorer on your Android phone, ES File Explorer is still worth a look
simply because it integrates so many different functions into a lightweight
app.
Apart from
the usual finding, cut, copy paste functions, it can manage installed apps
(uninstall too), function as a cloud storage client (compatible with Dropbox,
Google Drive, OneDrive, Box and others), kill tasks to free RAM, manage
downloads and act as a remote file manager (manage phone files from a
computer).
It supports
playback of all sorts of files and supports ZIP and RAR files natively.
10.
MESSAGING
If you’re
bored with the standard SMS app, give Textra a try. There are so many
features built in, plus it looks awesome!
If your phone
does not have a blacklist and you’re fed up with spam messages, get SMS Blocker Clean Inbox. Set it as the default SMS
app and it will automatically filter all spam. If you have a giant SMS inbox, TBox will help you get organized
(and search better) with auto archiving and smart labels.
For more SMS
functionality, try Chomp SMS (ad-supported). You need to
make it the default SMS inbox — in return, you get password protection, SMS
scheduler, lots of emoji, blacklisting, better group SMS features and loads of
free themes.
11.
SCANNER AND PDF MAKER
Since
smartphone cameras are getting better with every new launch, you don’t really
need a scanner unless you need very high quality results.
The most
popular free app you can get is CamScanner — it helps you capture a
photo of a document, cleans it up and saves it as a PDF. It does place a
watermark on the scan but it’s fairly unobtrusive.
You can pay
to remove watermarks and ads — plus add more features like optical character
recognition (OCR) and online storage.
12.
CALL RECORDER
This one is a
little tricky to pull off since many hardware makers will block access, which
means that either your voice will be recorded or the caller’s – but not both.
In some cases it can be blocked completely.
For call
recording to work, both voices should be recorded clearly. Try apps like RMC: Android Call Recorder, HD Call recorder, Total Call recorder or Call Recorder ACR(and use the speakerphone
while talking in case only one side is recorded). Some apps introduce a tiny
beep into the recording but if not, it’s also good practice to inform the other
party that the call is being recorded.
13.
LANGUAGE TRANSLATION
Google’s translation services are the go-to
option for a lot of people, but did you know it lets you download entire
language libraries to your device?
You can
choose which ones you want and download them at home (say before a trip) and
then keep doing those translations with an offline device. Note that this
applies only to text translations — you will need to type text.
To use the
voice translation or camera translation feature (you can point the phone camera
at a signboard, for instance), a network connection is still needed.
14.
LAUNCHER ENHANCEMENTS
A new
launcher is an easy way to entirely change the look and feel of the device (and
there are so many fast and lightweight launchers available in the store).
However, if
you like your default launcher and prefer to add more features rather than
replace, try a free app called Lazy Swipe. It automatically figures
out what you use most and places them all in a nicely animated radial menu that
you access by swiping from the screen’s lower left or right corners. As a
bonus, it also helps you easily navigate large screen phones with just a thumb.
Other similar
enhancements you can try are EasyTouch and Floating Toucher (both are like floating
toolbars, similar to iOS’s assistive touch, and you can use them to toggle
Android settings, clean memory, open apps and so on).
