                       users should know where to draw the line and not

                       you may find all you need with a particular

                       portability it offers and also make contingencies
                       should the service be terminated abruptly.

storage space and better security. Some storage
services also enable you to sync data across devices
so that files added to one device are automatically
uploaded to the cloud, and in some cases, even
downloaded to other synced machines.

The cloud computing system can be divided into
two distinct sections. At the front end, there is the
user, who can access the cloud server and includes
their machine and any application required to
access the cloud. The back end is the hardware
that makes up the cloud, which includes comput-
ers, servers and data storage systems that can be
accessed by the users. Cloud systems use middle-
ware, which is software that communicates with
various users connected to a single cloud server. It
monitors the system, managing traffic and client
demands to ensure that everything runs smoothly
and efficiently.

The advantages of cloud computing are fairly obvi-
ous. Users have access to their applications and
data from anywhere at any time and they can
access their information from multiple machines;
their data and software is no longer confined to
a single machine. Cloud computing also brings
down hardware costs, as users no longer need to
purchase the fastest computers with high end con-
figurations. The cloud system handles the load for

you. Essentially, all you need is a basic computer,
input devices and an Internet connection to access
the cloud services. Cloud storage enables users to
create backups of their data so if their machines
crash, they no longer need to worry about data
loss. Cloud servers can sometimes be a safer option
for protecting your data from viral infection or
damage due to the vast amount of online threats
and viruses circulating on the Internet.                around the world are accessing the server. Privacy
                                                        is another issue with cloud servers. Ensuring that

                                  Exchanging files, data and information by e-mail or on physical storage
                                  is a thing of the past. Cloud computing not only allows you to share files
                                  via cloud servers, but there is also software that enables you to work
                                  collaboratively in real time.

  With the growing popularity of cloud computing,
  several companies have started cloud services of
  their own. The stability of such companies, espe-
  cially start-ups, is questionable considering today’s
  volatile market. It can be inviting to make use of
  third party’s software and hardware to work on
  and store your data, but keep in mind that you are
  relying on that company for your data. If the com-
  pany goes out of business, you could lose your data
  and the services that you have been availing of. You
  might be under the impression that established
  service providers like Google or Apple would not
  shut down a service or go out of business, but even
  they have discontinued SaaS products in the past.

can upload up to 2 GB of files and as soon as the
upload begins, you are provided with a URL for

site, you will need an FTP client. Popular blogging
sites like Wordpress also enable you to use an FTP
server along with a customised CMS to edit your
posts offline and synchronise posts when you go
online. But if you are looking at a more free-flow-
ing website layout, Wordpress may not be too use-
ful. If you want to stick to the blog layout but find
Wordpress to be too complicated, you can link your
Wordpress account to this free account as well for
ease in access.
    In this workshop, we’ll be using the Filezilla FTP
client. Go to ‘’ and down-
load the appropriate version of Filezilla. We will be
using the Windows version of the application. Save
and execute the file to install it on your system.
                                                         Applications like Notepad++ can be of help if you want to edit files

You can use web design applications like Dream-
weaver and Flash to create your website. For this
workshop, we will be creating a photo gallery
using a free image editor called IrfanView. Go to
‘’, download the executable file
and install the application. Follow the process as
directed through the installation screens. Collect
all the images you want to upload to your online
image gallery. You can customize the image gal-
lery before you upload it. To do so, go to the ‘File
| Thumbnails’ menu on the main application win-
dow. Browse for the folder containing the images
in the folder tree appearing on the left-side of the
‘IrfanView Thumbnail’ window.
    It is a good idea to keep your photographs and
images in a separate folder, and name them as per        To use the ‘’ subdomain, you will have to register

that require permissions, make sure you secure
them and pay the required royalty before putting
them on your website.
    To continue, go to ‘Options | Set thumbnail
options…’ in the ‘IrfanView Thumbnail’ window,
and check the ‘Use Resample instead of Resize for
creating thumbnails (slower, but better quality)’
option. Set the thumbnail size as either ‘100 x 100’
or ‘80 x 80’ pixels from the ‘Thumbnail size’ drop-
down list. Click ‘OK’ to save the settings. If you
haven’t arranged the images, you can drag and
drop them in the sequence that you require. Once
your images are finalized, select all the images
from the ‘IrfanView Thumbnail’ window.

    DSK Supinfocom (Animation) had three events,
namely Mobile movie making, Light painting and
T-shirt design.
    For Mobile movie making, participants had to
shoot a two-minute short movie on a given topic
using only mobiles. Computers were given by the
college for editing and the participants could use
anyone or anything on the campus as props and/
or actors to make their short film.
    For T-shirt design, all the raw materials includ-
ing the t-shirts were provided by the college and
all the participants had to do was to come up with
a design and paint it on the t-shirt in one hour.
Of course, themes were provided by the college to
choose from.
    Light painting was a very unique and interest-

such as textile buildings, there are many lights
lit up continuously day and night in their large
work places. These lights operate at full power
and produce maximum luminance at all times,
but the human eye has a unique character of
perceiving the light intensity and the actual lumi-
nance. As power to the lights is reduced, the light
level decreases but the human eye may perceive
a higher light level than is actually recorded by a
light meter. This yields the ‘square law’ curve, the
theoretical relationship between measured light
level and perceived brightness. Hence, the proj-
ect proposes a method to make the level of the
brightness as required for the human to be con-
stant even after reducing the actual power input                  ABOUT THE INNOVATORS
