1. Beginning Ubuntu
 means 'humanity towards others' in Xhosa and Zulu language. Mark 
Shuttleworth contributed lot of efforts to the development of Debian. He
 came with an idea of developing user friendly, feature rich Linux 
desktop distribution. He self-funded the early stage of company. 2. First Mark
 Shuttleworth sold his company, Thawte to VeriSign for half a billion 
dollars in 1999. He used the money to fund development of Ubuntu. The 
first public version of Ubuntu 4.10 was released in October, 2004. It 
was called Warty Warthog. 3. Growth The word 
spread very quickly amongst open source community. People started 
testing Ubuntu. The OS got very positive reviews for the early 
development stage version of the OS. Distrowatch website, which used to 
rank open source softwares, ranked Ubuntu on the first rank in the list 
of open source Linux distributions. 4. Flavours Ubuntu
 started using different desktop environments, Xubuntu (XFCE), Kubuntu 
(KDE) and Lubuntu (LXDE) gained popularity in no time. Plenty of 
official, non official flavors of Ubuntu were produced after that. Like,
 Ubuntu Kylin, Edubuntu, Mythubuntu etc. 5. On Top Ubuntu
 had no real rival back then. It didn't take much time for Ubuntu to 
become most popular desktop Linux distribution. It was the best option 
for newbie Linux users, and even those who were planning to migrate from
 Windows. 6. Mint In 2011, Linux Mint gained 
popularity amongst users. Mint offered more customization options than 
Ubuntu and it had rich user interface as compared to Ubuntu. This is 
when Ubuntu found it's real competitor. 7. Unity Unity
 desktop interface was considered as major reason for the failure of 
Ubuntu. This custom build desktop user interface was the reason behind 
the success of GNOME 2.8 but, according to Ubuntu criticizers, Unity was
 poorly designed and it seemed unfinished. 8. Privacy More
 polished and usable version of Unity was introduced in Ubuntu 12.04. 
But in in Ubuntu 12.10, the shopping lens was added. And Ubuntu again 
became the attack of criticizers due to user privacy invasion. 9. Mobility Last
 few years, Canonical has moved it's focus from desktop distribution 
development to mobile platforms. Company released Ubuntu Touch last 
year. Ubuntu Touch also works on Android devices. Company is working 
with some manufacturers in development of devices running Ubuntu Touch 
out of the box.

Basics of GPS: GPS
 works when signals gets transmitted from satellites in space and get 
received by receivers on or near Earth. Timing is used to determine the 
distance of each satellite which gives the knowledge of satellite 
positions on earth. The satellites also transmit information about their
 positions and the receiver becomes able to calculate the distance from 
the satellite to the receiver. A fully operational GPS satellite system 
features 24 operational satellites and the satellites are in one of the 
six orbits. Each orbit has four satellites at 55 degree to the 
equatorial plane. It ensures that between five to eight satellites can 
be accessed any time at any point on the Earth. If GPS receivers 
are economically manufactured then they can provide information to 
within a number of metres. GPS receivers are now fitted to motor 
vehicles and private individuals also use these receivers to a large 
extent these days. Primarily GPS is used for military navigation system. Know about GPS satellites and receivers: Satellites
 keep orbiting above the Earth and heavy controls are kept on these 
satellites as if these satellites are at error, then the final results 
will also be mistaken. An atomic clock is kept in the satellites to 
ensure accurate time signals. GPS satellites have a design life of ten 
years but still spares are held in orbit so that unexpected failures 
don't cost much. GPS receivers use digital signalling processing 
techniques. Transmissions from satellites are done through spectrum 
technology and the signals are correlated by signal processors to 
recover data. The GPS receivers in use must be kept in open as they 
can't operate inside buildings. How GPS receivers work: GPS
 receivers follow certain processes in their functions. 2-D 
Trilateration, 3-D Trilateration and GPS calculations are some of the 
processes that GPS receivers follow while functioning. Radio waves are 
used in GPS receivers for electromagnetic energy. At a particular time 
the satellite begins transmitting a long digital pattern and when the 
signal reaches the receiver its transmission of the pattern lags a bit. 
This measurement can be done through clocks and nanoseconds on those 
clocks, rather atomic clocks. GPS control network: GPS
 satellites are monitored and controlled from the ground and contact 
with each satellite is highly required to maintain the level of 
performance. Information from remote stations is passed to the main 
operational centre at Colorado Springs and then proper assessment of the
 information is done. Orbit and clock performance are closely monitored. GPS signal basics and signal data: GPS
 satellites transmit variety of signals and there are two main 
frequencies which are used in the transmission of the GPS signal. GPS 
signal carries three types of data: Pseudo-random code, Ephemeris data 
and Almanac data. GPS Applications: As we said 
earlier, GPS is primarily used as military navigational assistance. 
American Department of Defense runs GPS but now it's applied for several
 commercial purposes all across the globe like aircraft navigation, ship
 navigation and any kind of location information. Cost effective GPS 
receivers are available these days and they are integrated into satNav 
systems in motor vehicles so that navigation becomes easy without any 
additional map. GPS has brought a revolution in global navigation
 as before its arrival, navigation systems were limited to local spheres
 without any kind of accuracy or flexibility.

1. Material Design: Google's
 last design language was Holo which was replaced by Material Design. 
Google went on updating design guidelines for developers to start making
 Material apps. But with Lollipop, Google is focusing on the main thing –
 Android's consistency across all devices. Android Lollipop will be 
omnipresent across phones, tablets, watches, cars and TV too. Lollipop 
will have a flat look for its UI and all icons. The Material Design 
means menus will respond more promptly. So Android Lollipop is all about
 consistent design experience across all Android devices and with this 
design, elements can dynamically shrink and expand and most importantly 
the interface has a 3D appearance overall. 2. Battery life fixes: Google
 has added a new battery saver feature to the latest Android version 
which claims to extend the battery life of devices up to 90 minutes. 
This Android version will display the estimated time left to fully 
charge the device when plugged in and also the time left before the user
 needs to recharge the device. Android phones have always suffered from 
battery life issues due to apps and services running in the background. 
The power saving mode has been missing from Android old stocks. You'll 
be able to restrict syncing, background data and also screen brightness 
to expand battery life. The power saving mode has been tuned in a better
 way to the Android 5.0 Lollipop. The battery use menu has got a better 
graph which informs which apps are draining the battery. More battery 
life is always welcome so Android Lollipop is a win-win situation for 
millions of Android users across the globe. 3. Notification settings: Android
 5.0 Lollipop has lock screen displays and rich notifications settings. 
Users can view and respond to messages directly from the lock screen and
 the richer notification settings in the new Android version includes 
floating descriptive notifications on the top of activities. These 
notifications can be viewed or dismissed without moving away from any 
activity. On Android Lollipop Google has offered better control over 
notifications. Users can control notifications from apps and sensitive 
content can kept hidden. The 'Priority mode' can also be turned on via 
the volume button of the device. There is one more feature called 'Do 
Not Disturb' mode, just like in Apple iOS, which allows users to 
selectively silence notifications and calls. The entire look and feel of
 the notifications is changing as lock screen can be easily accessed 
now, along with a revamped pull-down menu. The layout and location of 
notifications have been completely changed and lock screen widgets are 
removed from Android 5.0. 4. Security enhancements: Android
 5.0 will allow encryption by default. You can encrypt your Android 
device now too, though it may be a painstaking job. You need to plug in
 your phone and the encryption process will take minimum 30 minutes. And
 just to warn you, if anything goes wrong, your data will get lost. But 
with Android 5.0 encryption will be an automatic thing. Android 5.0 
features an opt-in kill switch known as 'Factory Reset Protection' which
 allows users to wipe out the device's data as per their wish. With this
 Android you can also unlock your phone in an easier way without 
entering a PIN or drawing the pattern. You can use an Android watch to 
unlock your phone which is kept in close proximity. Lollipop also comes 
with SELinux enforcement which means better protection against viruses 
and malware. 5. New Quick Settings: Google wants 
to curb swipes on devices which are needed to access important functions
 like Wi-Fi, Bluetooth and GPS activation. The new Android includes 
built-in tools for flashlight, hotspot and screen cast controls which 
means you can get rid off many third party apps now. Setting up an 
Android device will become faster now with Android 5.0 as the new 
Android device can be set up just by tapping it on the old device, 
though it requires NFC support. All apps from Google play will be 
transferred to the new device, if the same Google account is used. In 
certain situations, you can also adjust brightness manually. 6. New Messenger App: A
 new Messenger app is present in Android 5.0 which comes with Nexus 6 
which is said to be a simplified version of Google Hangouts. This 
Messenger has been designed for sending and receiving SMS and MMS 
messages on Android in a quicker and easier way. More updates about this
 Messenger are still awaited though. 7. Performance Boost: Android
 5.0 supports 64-bit and the new Nexus 9 also features a 64-bit chip, 
though Nexus 6 doesn't. Well this kind of performance boost will not 
make a very huge difference for average users but Google will be 
shipping native 64-bit versions of Gmail, Maps and other apps too. But 
this development will not mean much if you are using a 32-bit device 
only. The runtime environment in the new Android version is ART which 
promises four times better performance and better desktop level graphics
 performance too. 8. Updated camera: The updated 
camera settings supports advanced features like burst mode and fine 
settings tuning. Full resolution frames around 30fps can be captured in 
this new update and shooting can be done is raw formats like YUV and 
Bayer RAW. Android 5.0 also supports UHD 4K video playback, tunneled 
video for high quality video playback on Android TV and also improved 
live streaming. Professional features have also been added like 
controlling settings for the sensor, lens and flash per individual 
frame. In Android 5.0 developers will be able to implement their own 
technology to take full advantage of hardware and any mediocre camera 
can be transformed to a better one. 9. Device Sharing: Device
 sharing features have been integrated in Android 5.0 which allows users
 share their device with family members and friends without giving 
access to sensitive content. It features a guest user mode with custom 
options for access which allows users fix the place of the screen which 
is displayed. There is also a feature in Lollipop which allows users log
 in to another Android phone to access synced messages and content, if 
the device is forgotten at home. 10. Other Updates: There
 are some more features in this OS and more fixes and improvements. In 
this new OS finding things will become easier with improved search 
indexing and search results will be saved across different apps and 
devices. Other relevant features of Android 5.0 include improved 
hardware keyboard accessory support, support for 15 new languages 
including Bengali, Kannada, Malayalam, Marathi, Tamil and Telugu, 
improved audio and video capabilities and improved Internet connectivity
 with more powerful Bluetooth low energy capabilities.

1. Column-oriented databases: Traditional
 databases are excellent in online transaction processing but when it 
comes to query performance while data volumes grow, these databases fall
 short on performance. The new column-oriented databases store data and 
focuses on columns and not rows. It allows huge data compression and 
faster query times. 2. Streaming Big Data analytics: There
 are several projects in this section including Storm, Spark, Data 
Torrent, Spring XD and SQL Stream. Apache Storm is an open source 
distributed real-time computation system which simplifies streams of 
data and real-time processing. Spark is a data processing platform which
 is compatible with Hadoop. DataTorrent is a real-time streaming 
platform which enables businesses to perform data processing. Spring XD 
supports streams for event driven data while SQLStream provides a 
distributed stream processing platform for streaming analytics, 
visualization and continuous integration of machine data. 3. Schema-less databases, or NoSQL databases: This
 database category includes key-value stores and document stores. This 
database focuses on storage and retrieval of large volumes of 
unstructured, semi-structured or even structured data. 4. SQL-in-Hadoop: This
 technology includes Apache Hive, Shark, Apache Drill, Presto and 
Phoenix among many others. It helps in making queries and it also 
manages large datasets in distributed storage. Shark is a data warehouse
 system which supports Hive's query language. Apache Drill is an Apache
 incubation project and it's designed for scalability. It's backed by 
MapR. Presto is an open source distributed SQL query engine and Phoenix 
is an open source SQL query engine for Apache Hbase. 5. MapReduce: It's
 a programming paradigm which allows massive job execution scalability 
against thousands of servers or clusters of servers. Its two tasks are 
Map task and Reduce task. It converts any input dataset into different 
set of value pairs while reducing set of tuples. 6. Hadoop: Hadoop
 is an open source platform for handling Big Data which can work with 
multiple data sources. It has other applications too and it's largely 
used for changing data like location-based data from weather or traffic 
sensors, web-based or social media data or machine-to-machine 
transactional data. 7. PIG: PIG brings the Hadoop
 project close to developers and business users and it's used by Perl 
like language allowing query execution over data stored on a Hadoop 
cluster. PIG was a project by Yahoo! But now it's completely open 
source. 8. Big Data Lambda Architecture: Lambda 
Architecture is a hybrid platform which combines real-time data and 
pre-computed data to provide a near-real time view of the data at all 
times. Its frameworks include Summingbird by Twitter and Lambdoop. 9. PLATFORA: It
 almost copies Hadoop and it requires developer knowledge to operate. 
It's a platform which turns queries into Hadoop jobs with immediate 
effect and creates an abstraction layer to simplify the datasets in 
Hadoop. 10. SkyTree: It's a high performance machine learning data analytics platform which handles Big Data. It's an essential part of Big Data.
