Moral: Customer is always right listen him thoroughly and believe what he is saying.

CFL (Compact Fluorescent Lamp)


CFL (Compact Fluorescent Lamp) converts electrical energy to radiant energy. They are energy efficient and use better technology as compared to conventional tube lights and bulbs. It has two components:
a)      A glass tube filled with argon and mercury vapor & coated with a layer of fluorescent material.
b)      An electronic ballast circuit.
 
CFL Insight 
A 25 Watt CFL is shown in the above image.
 
CFL Insight2 
The above image shows the circuit for electronic ballast. This circuit takes a 220 V input from external power source and sends a current into the fluorescent tube as output. We can divide the circuit in two parts. Supply section and starting circuit. Supply section contains a coil, fuse, a bridge rectifier using diodes and a filtering capacitor. Starting section includes a diode, a capacitor, resistance and DIAC (Diode for Alternating Current).
 
CFL Insight3 
A closer look to its component can be viewed in the image.
 
CFL Insight4 
The circuit has two terminals – Cathode and Anode which are inserted into the ends of the fluorescent tube. When the power is supplied to the circuit, Cathode is heated enough to emit the electrons into the tube. These electrons travel through the tube and reach another end of the tube where they are received by anode.
 
CFL Insight5 
A filament is shown in the above image, both end contains the same filaments.
 
Working: The tube is filled with Argon and mercury vapors. When power supply is given to the CFL, filament attached with the cathode heats up and emits electrons in the tube. This ionizes the argon and mercury vapor particles. The ionized particles emit ultra violet radiations which strike with the fluorescent layer of material coated on the tube. In turn, fluorescent material spread a white light which lights up the room.

Use Facebook at Office Work in form of Excel Sheet without getting caught


ALT + TAB to switch between Work Window and Facebook is common and working trick but not so secure so, here is a trick which will let you access Facebook imitating your work. By work, I am pointing to the Excel Sheet.
The idea is simple: All your Facebook statuses are presented as if it were an Excel document. Updates from your friends, new photos, comments, changes of state, likes, events calendar, and so on. Much information as possible from a single interface Excel, one book and several sheets.
Facebook Excel Sheet
Imagine yourself working in a Bank or IT sector where accessing Facebook could drag you to problem. In such a situation, HardlyWork.in comes to rescue.
HardlyWork.in is a web application which converts your Facebook wall including all details into Excel Sheet. Visit their site and once and only once, you have to provide access to HardlyWork.in application and that’s it.
All statuses are shown in Excel Sheet Cells. External links can be clicked to open in new tab. While Photo updates can be seen by hovering mouse on it. Thumbnail is shown on right bottom and full width image can be seen by clicking on link.
The program has been designed in the end so you can see Facebook from work, and it even has apanic button that is activated by pressing the space bar, which automatically converts content of the cells to numeric values, just in case the boss comes up unexpectedly appear and engage in the detail of your work. Now convincing your Boss about Numbers and your work depends on your creativity :)
For better results- get your Web browser to Full screen so that just the application is shown which exactly resembles like Excel sheet.
Mere... Company kee ladkiyaan sunder aur lonely hain...
Problem ye hai ki bus voh READ-ONLY hain...




Shayad mere pyar ko taste Karna bhool gaye...
Dil sey aisa CUT kiya ke PASTE karna bhool gaye..




Tumhare samne hain itney items Kabhi hame bhi pick karo...
Hamare pyar ke ICON pe Kabhi to tum DOUBLE-CLICK karo...




Roz subha hum karte hai Itne pyar se unhe good morning...
Woh humhe ghoor kar dekhte hain Jaise 0 ERRORS but 5 WARNINGS...

Duniya ki parwaah chhodo, ban jaao meri spouse!




Tumse mila main kal to, Mere dil mein hua ek sound,
Lekin aaj tum mili To kehti ho: Your file not found!



Ab aur kaho na tum, "but" ya "if"
Tum ho meri zindagi ki animated gif




Aisa nahin hai ke, I don't like your face
Par dil ke computer mein, Nahin hai enough disk space




Ghar se nikalti ho tum jab, Pehen ke evening gown
Too many requests se, Ho jaata hai server down




Tumhaare liye pyaar ki application, Create main karoonga
Tum usse debug karna, Wait main karoonga




Tumhaara intezaar karte karte, Main so gaya
Yeh dekho mera connection, Time out ho gaya



Kya chaal hai tumhaari, Jaise chalti hai koi cat
What is your ICQ number, Aao karein chat



Tum jabse meri zindagi, mein aayi ho banke female,
Yaad raha na ab kuch, Na postman , Na e-Mail



Joh sadiyaon se hota aaya hai Woh repeat kar doonga...
Tu naa mili to tujhko dil sey Ctrl+Alt+Delete kar doonga...



Humse Kya Khata Hui Ki message Aanna Band Hai.......
Aap hi humse naraz hain ya Web Server band hai.......




Badli hai duniya , kuchch mein bhi badal gaya hoon
Pahle bekaar tha ab S/W Programmer ban gaya hoon

Android


World is contracting with the growth of mobile phone technology. As the number of users is increasing day by day, facilities are also increasing. Starting with simple regular handsets which were used just for making phone calls, mobiles have changed our lives and have become part of it. Now they are not used just for making calls but they have innumerable uses and can be used as a Camera , Music player, Tablet PC, T.V. , Web browser etc . And with the new technologies, new software and operating systems are required.
 

 
 
 
 
 
 
 
Introduction
Operating Systems have developed a lot in last 15 years. Starting from black and white phones to recent smart phones or mini computers, mobile OS has come far away. Especially for smart phones, Mobile OS has greatly evolved from Palm OS in 1996 to Windows pocket PC in 2000 then to Blackberry OS and Android.
 
One of the most widely used mobile OS these days is ANDROIDAndroid is a software bunch comprising not only operating system but also middleware and key applications. Android Inc was founded in Palo Alto of California, U.S. by Andy Rubin, Rich miner, Nick sears and Chris White in 2003. Later Android Inc. was acquired by Google in 2005. After original release there have been number of updates in the original version of Android.
 
Android Versions and Updates
 
Features & Specifications
Android is a powerful Operating System supporting a large number of applications in Smart Phones. These applications make life more comfortable and advanced for the users. Hardwares that support Android are mainly based on ARM architecture platform. Some of the current features and specifications of android are:
 
Features of Android OS
Android comes with an Android market which is an online software store. It was developed by Google. It allows Android users to select, and download applications developed by third party developers and use them. There are around 2.0 lack+ games, application and widgets available on the market for users.
 
Android applications are written in java programming language. Android is available as open source for developers to develop applications which can be further used for selling in android market. There are around 200000 applications developed for android with over 3 billion+ downloads. Android relies on Linux version 2.6 for core system services such as security, memory management, process management, network stack, and driver model. For software development, Android provides Android SDK (Software development kit).
 
Applications
These are the basics of Android applications.
•      Android applications are composed of one or more application components (activities, services, content providers, and broadcast receivers)
•      Each component performs a different role in the overall application behavior, and each one can be activated individually (even by other applications)
•      The manifest file must declare all components in the application and should also declare all application requirements, such as the minimum version of Android required and any hardware configurations required
•      Non-code application resources (images, strings, layout files, etc.) should include alternatives for different device configurations (such as different strings for different languages)

Google, for software development and application development, had launched two competitions ADC1 and ADC2 for the most innovative applications for Android. It offered prizes of USD 10 million combined in ADC1 and 2. ADC1 was launched in January 2008 and ADC 2 was launched in May 2009. These competitions helped Google a lot in making Android better, more user friendly, advanced and interactive.

Other Mobile OSs
There are different other Mobile operating systems also present in market in competition with Android. Apple's iOS and Windows Phone give strong competition to Android. A simple comparison between features and specifications of latest version of Android and other Operating Systems can be seen in the table given below.

Comparison between different Mobile OSs : Android, Apple iOS, Windows Phone 7, Nokia Symbian
 
According to Canalys, In Q2 2009 Android had 2.8% market share which had grown to 33% market share by Q4 2010 which made Android leader of smart phone OSs worldwide. The market share for commonly used mobile OSs is shown in the following pie chart.

A large no of mobile companies are using Android. A list of companies supporting Android in their hardware is:

Change the Terminal Background Color

"tput" is a standard Unix operating system command which is used to
set terminal features. Depending on the system, tput uses the terminfo
or termcap database, as well as looking into the environment for the
terminal type.


Change the Terminal Background Color using tput setb

Using tput, the background color of the screen can be changed as shown below.

$ tput setb 4

Change the Foreground Color using tput setf

You can also change the foreground color of the terminal as shown below.

$ tput setf 5

Note: If you set foreground and background to the same color you
cannot see the cursor. So, to reset, execute “tput reset”.

Color info:  1: red, 2: Green, 3= Yellow, 4= Blue, 5= Purple, 6= Cyan, 7= White

જાણીએ દુનિયાની 10 એવી અનોખી વિજ્ઞાનની શોધો વિશે....


ડાર્વિનના ઉત્ક્રાંતિવાદથી માંડીને આજના કમ્પ્યુટર સેવી યુગ સુધી વૈજ્ઞાનિકોએ સતત શોધ અને સંશોધન દ્વારા જગતને એક નવી દિશા આપી છે. જે કામ વર્ષો પહેલા કદાચ અમુક વર્ષોમાં પૂરા થતા તે આજે ઘડીના છઠ્ઠા ભાગમાં કે સેકન્ડમાં પૂરા થઈ જાય છે. વિજ્ઞાનની અવનવી શોધોએ માનવીની જાણે કે આખી જીવનશૈલી જ બદલી નાંખી છે. 

1.એન્ટીબાયોટિક્સઃ 3 સદી પહેલા મોટા ભાગના લોકો ઈન્ફેક્શનના કારણે મરતા હતા. 1347માં ફેલાયેલા પ્લેગે તો જાણે વિનાશનું રૂપ લઈ લીધું હતું. આ પછી ધીમે ધીમે એન્ટીબાયોટિક્સનું ચલણ વધ્યું અને લોકોનો મૃત્યુદર ઘટ્યો.

2. ઈલેક્ટ્રિસિટીઃ એક ક્ષણ માટે વિચારો કે જો ઈલેક્ટ્રિસિટી ન હોત તો? કલ્પના જ ન થઈ શકે. એડિસનને વીજળીની શોધના પિતા માનવામાં આવે છે અને પર્લ સ્ટ્રીટ સ્ટેશન પહેલુ ઈલેક્ટ્રિક પાવર સ્ટેશન હતું.

3.પ્લાસ્ટિકઃ જો કે હવે આ શોધનો વિરોધ થઈ રહ્યો છે, પણ તમે તમારા ઘરમાં જ એક નજર કરજો તો ખબર પડશે કે પ્લાસ્ટિક વગર આજે ચાલે તેમ છે? પહેલુ પ્લાસ્ટિક સિન્થેટિક પોલિમર પર આધારિત હતું, જે ફિનોલ અને ફોર્માલડિહાઇડમાંથી બનેલું હતું.

4.ટ્રાન્ઝિસ્ટર્સઃ ટ્રાન્ઝિસ્ટર્સ દ્વારા કોમ્પ્યુટર, સેલ્યુલર ફોન અને અન્ય ઘણા બધા ઈલેક્ટ્રિક ઉપકરણોના ઓપરેશન્સ પાર પાડી શકાય છે. 16 ડિસેમ્બર 1947ના રોજ વિલિયમ શોકલી, જોન બાર્ડીન અને વોલ્ટર બ્રેટેઇને બેલ લેબ્સમાં પહેલુ પ્રેક્ટિકલ પોઇન્ટ કોન્ટ્રાક્ટ ટ્રાન્ઝિસ્ટર બનાવ્યુ હતું.

5. કોમ્પ્યુટરઃ 1837માં ચાર્લ્સ બેબેજે પહેલુ પ્રોગ્રામેબલ મિકેનિકલ કોમ્પ્યુટર બનાવ્યુ હતું, જે ‘ધ એનાલિટિકલ એન્જિન’ તરીકે ઓળખાયુ હતું. જે ધીમે ધીમે નાનુ રૂપ ધારણ કરતુ ગયુ અને અત્યારે તો પોકેટ કમ્પ્યુટરના રૂપમાં પણ મળવા લાગ્યું છે.

6.સ્ટીમ એન્જિનઃ થોમસ સેવરી ઈંગ્લિશ મિલિટ્રી એન્જીનિયર હતા અને 1698માં પહેલુ ક્રૂડ સ્ટીમ એન્જિન પેટન્ટ કરાવ્યુ હતું. આ પછી 1712માં થોમસ ન્યુકોમેને એટ્મોસ્ફેરિક સ્ટીમ એન્જિનની શોધ કરી હતી.

7. પેસ્ટીસાઇડ્સઃ આ શબ્દ ખેતી જેટલી જૂની છે, તેટલો જૂનો તો નહીં કહી શકાય. 15મી સદીમાં આર્સેનિક, મર્ક્યુરી અને લીડ જેવા ટોક્સિકનો પેસ્ટિસાઇડ્સ તરીકે ઉપયોગ થતો હતો. આ પછી 1939માં પોલ મિલરે પહેલી વાર અસરકારક પેસ્ટિસાઇડ તરીકે DDTની રજૂઆત કરી. પેસ્ટિસાઇડ્સ વગર પાક સરખો રહે તેની કલ્પના પણ ન કરી શકાય.

8. ઓટોમોબાઇલઃ 1769માં ફ્રેન્સ મિકેનિક નિકોલસ જોસેફ કુગ્નોટ દ્વારા પહેલુ યાંત્રિક વાહન રજૂ કરવામાં આવ્યુ હતું. તે સ્ટીમ પાવરથી ચાલતુ મોડલ હતું. આ પછી 1885માં કાર્લ બેન્ઝે દુનિયામાં સૌ પ્રથમ વખત ઈન્ટરનલ કમ્બશન એન્જિનની મદદથી પહેલી ઓટોમોબાઇલ કાર બનાવી.

9. પ્રિન્ટિંગ પ્રેસઃ પ્રિન્ટિંગ ક્ષેત્રે ઘણા બધા રિફોર્મ પછી અત્યાધુનિક તક્નીક આવી હતી. સૌ પ્રથમ પ્રિન્ટિંગ પ્રેસ જોહાનિસ ગુટનબર્ગે યુરોપમાં સ્થાપિત કર્યુ હતું. આજે પ્રિન્ટિંગ ક્ષેત્રે અકલ્પ્ય સિદ્ધિઓ હાંસલ કરી લીધી છે.

10. મોડર્ન પ્લમ્બિંગઃ તમે ગામડામાં ખુલ્લી ગટરો જોઈ હશે. પહેલા જ્યારે શહેરોનો વિકાસ નહોતો થયો ત્યારે પ્લંબિંગનો પણ બહુ ઓછો વિકાસ થયેલો હતો. હવે પ્લંબિંગ ફેસિલિટી વગર એક સાધારણ ઘરની કલ્પના કરવી પણ મુશ્કેલ છે, ત્યાં હાઇરાઇઝની તો વાત જ દૂર રહી. આ ક્ષેત્રે એકસામટો નહીં પણ ક્રમાનુસાર વિકાસ થયો છે.

Military Robotics


The utilization of Robotics in military is well shown by US army. Osama and other terrorists were tracked by these military robots. They are robust, they are obedient, they are daring, they don’t have fear of death, and most important they have proved themselves in Iraq and Afghanistan. Now, terrorists are terrified by drone attacks. The utilization of robotics technology in military led to a new field in robotics i.e. Military Robotics.
 
 

Military robotics isn’t about creating an army of humanoids but utilization of robotics technology for fighting terror and defending the nation. Thus, military robots need not be humanoids or they not necessarily need to carry weapons, they are just those robots that can help the armed forces. The opportunities offered by these technologies are boundless. Apart from army research centers there are many private firms also which provide military robots for defense forces like Foster Miller,21st Century Robotics, EOD PerformanceNorthrop Grumman,General Atomics etc. They have created many job opportunities and are developing this sector. It is expected that its market will extend up to $9.8 billion by 2016.

History 
The vision of robot army isn’t a present day concept. The introduction of military robots is dated back from 1898 by the introduction of radio boats by Nicola Tesla. It was visualized by many visionaries in the last century. They were used by Germans and Russians in Second World War. Russians used Teletanks and Goliath were used by Germans. The Teletanks were equipped with DT machine guns, flamethrowers and smoke container to provide a smokescreen. The use of Goliath which is a mobile landmine in World War II by the Third Reich's forces also marked as a turning point in the history of military robots. And today the development in this technology is well demonstrated by military robots in Afghanistan and Iraq. At present the most commonly used military robot is the unmanned aerial vehicle IAI Pioneer and RQ-1 Predator.
 
One threatening question must be arising, as in every science fiction movie, it is shown that robots have gone crazy and started hunting us, will they go crazy in real world also? Actually, at present it is almost impossible. The developers have very well taken care of this aspect. Most of the military robots are remotely controlled by a human. And if someone has gone crazy then there is a reset button which clear there memory and they again come back to normal state. But with the development in artificial intelligence and military robots, there should be greater attention to implicate their ability to make autonomous decision.
 
Operations
 Today military robots use very sophisticated and advance technology for operations. They use different technologies for reconnaissance, guidance and weaponry. They basically use GPS, Fiber Optic Tethers, LIDARs for guidance. GPS is based on satellite connections and is even used in mobile phones. The fiber optics is a hi-tech and hi-speed communication system especially used by defense. LIDARs are based on laser communication and nowadays used by traffic police to detect over speeding vehicles. For reconnaissance they use other technologies like cameras, electronic RF sensor, RADAR, etc. The robots are mainly used for reconnaissance purposes but they can also carry lethal and non-lethal weapons like AGM-114 Hellfire missiles, M249 saw machine guns, ammo can, bomb diffusal kits, grenades, etc.

VARIETIES
Military robots come in different shapes and sizes as per the task they are designated for. In the development of military robots, we can consider US Mechatronics which has created or developed a working automated sentry gun and is presently developing it further for commercial as well as military use. As far as military robots development is concerned, we cannot forget MIDARS which is a four-wheeled military robot. This robot is outfitted with many cameras, radar, and a firearm that performs arbitrary patrols around a military base automatically. Their size can vary from a small bot TALON and large UAV MQ-1 Predator. Their design is also task specific like, predator is for surveillance and attack from air so it is more like an airplane while TALON is for attack from ground so it is more like an armoured tank. There are three popular classes of military robots i.e. UGVs, UUVs and UAVs.
 

UGVs i.e. Unmanned Ground Vehicle are those which attack from ground. They have various sensors, cameras, arms mounted on them. The UGV like big-dog has been devised as four legged bot it can carry heavy loads that were used to be carried by soldiers. It has capability to carry load on uneven terrain. Robots like packbots are so compact, light and robust that army can carry them on their back.Controlled by a Pentium processor that has been designed specially to withstand rough treatment, Packbot's chassis has a GPS system, an electronic compass and temperature sensors built in. Packbot manufacturer iRobot says Packbot can move more than 8 mph (13 kph), can be deployed in minutes and can withstand a 6-foot (1.8-meter) drop on concrete -- the equivalent of 400 g's of force. Its design alows it to flip also. 
 
 
The other most popular robot is TALON. It is manufactured by Foster Miller. The TALON is a man-portable robot operating on small treads. It weighs less than 100 lbs (45 kg) in its base configuration. TALON is operated with a joystick control, has seven speed settings (top speed is 6 feet/1.8 meters per second) and can use its treads to climb stairs, maneuver through rubble and even take on snow.  Versatility has been designed into the TALON as well, with multiple possible configurations available that adapt the robot to the situation at hand. The basic TALON includes audio and video listening devices and a mechanical arm. A lightweight (60-lb/27-kg) version omits the arm. TALONs were used for search and rescue at WTC Ground Zero, and they have been used in Bosnia, Afghanistan and Iraq for the disposal of live grenades, improvised explosive devices and other dangerous explosives.
 
The UAVs are those which are used from air. They shouldn’t be confused with missiles. Actually missiles are weapons but UAVs aren’t weapons itself but they carry weapon. Some of the UAVs are RQ-11A/B RavenRQ-5A / MQ-5A/B HunterMQ-1 Predator , MQ-9 Reaperetc. Northrop Grumman and General Atomics are the dominant manufacturers in UAV industry. There are other countries except USA also in UAV technology like Israel, Europe, India, etc. which have successfully developed UAVs and are developing it further.
 
The military uses several different flying robots, mainly for reconnaissance. Instead of UGVs, these are known as UAVs (unmanned aerial vehicles), and they are sometimes referred to as drones. UAVs look like model aircraft, and they range in size from small planes that can be held by a person and launched with a good throw, like the FQM-151 Pointer, to full-size airplanes that operate by remote control, like the RQ-4A Global Hawk.

The next class is UUVs i.e. unmanned underwater vehicle. These marvels have capabilities to be operated underwater.  UUVs were envisioned to contribute to the following SSN mission areas: Mine Warfare (MIW); Intelligence, Surveillance, and Reconnaissance (ISR); and undersea environmental sensing and mapping. The Talisman UUV is a fully autonomous unmanned mini-sub designed and made by BAE Systems. It has the capability to perform shoreline reconnaissance when the risks may be deemed too high, or conditions unsuitable, for human operators. The Talisman system comprises a vehicle and remote control console. The vehicle can be re-programmed in mid-mission by satellite and features a carbon fibre hull giving it a stealth-like profile and low observability. Talisman can carry a wide variety of payloads, such as image capture, environmental sensors or mine counter measures.

Structure and design of predator
The Predator uses a lightweight, 4-cylinder snowmobile engine, which powers a rear-mounted propeller, making the Predator a "pusher"-type aircraft. It carries cameras and other sensors but has been modified and upgraded to carry and fire two AGM-114 Hellfire missiles or other weapons. Hence, it’s no wonder that technology is moving forward in the direction of creating army of robots that will not just make our life comfortable but also safe.

Expectations
In the near future robotics will reach new heights. All the dreams where robots do our jobs will come true. And military is not an exception. At present there are many hostile and painful tasks that have to be performed by humans but in near future most of them will be done by them. In future news headlines would be like”5 robos saved bank robbery”, “a robo team has vanished terror camp, no casualties reported” and many more. This future is very close.
 
There are many research and developments going on for replacing robots for humans in army. In U.S. there is a project going on, named project Alfa, a U.S. Joint Forces Command rapid idea analysis group, which is conducting a study focusing on the concept of developing and employing robots that would be capable of performing not all but almost all the functions in battlefield. The study, appropriately titled, “Unmanned Effects: Taking the Human out of the Loop,” suggests that by as early as 2025, the presence of autonomous robots, networked and integrated, on the battlefield might not be the exception, but, in fact, the norm. In support of the study, USJFCOM sponsored a workshop at Johns Hopkins University in Baltimore. The workshop addressed by experts in robotics and artificial intelligence, was designed to develop a skeletal operational concept for the employment of autonomous machines and to raise awareness throughout DoD about current robotic technology and it’s future potential on the battlefield. According to Gordon Johnson, the Unmanned Effects Team leader for Project Alpha, the aim of the study was to articulate a vision for the use of robotic forces and promote the formation of a Department of Defense-level office that will coordinate and integrate efforts across the armed services, ultimately resulting in joint-service development of unmanned effects (UFX), rather than the course of service-centric research that currently exists.
 
Now a variety of military robots is under consideration. TAC i.e. Tactical Autonomous Combatant is capable in working on ground, air, space, or undersea environments, and in humiliating conditions of extreme heat or cold. Further they will be capable of operating in chemically, biologically, or radioactive contaminated environments. As the name suggests TAC be autonomously operated or with very little human intervention though humans have to guide them but humans have to just guide them from miles away.
 
The present technology of military robotics is also amazing. The predator which is a latest UAV in service of USAF and Central Intelligence Agency(CIA) is in use since 1995, has seen combat over Afghanistan, Pakistan, Bosnia, Serbia, Iraq, Yemen and Libya .
