Some facts about java

Hello All ,

Java LogoThis is my First post about java. Everything has its own and very popular history. So when I think about java  the very first question arrived in my mind is how and why java ? Because we have c with us for the core programming and we have c++ for the entire object oriented concept. After going through a long discussion and from the internet I founded some facts which are sufficient for my queries.

So Let’ start with my first question

How we got java?

Java was created by a team led by James Gosling for Sun Microsystems, James Gosling, Mike Sheridan, and Patrick Naughton initiated the Java language project in June 1991. Java was originally designed for interactive television, but it was too advanced for the digital cable television industry at the time.

The language was initially called Oak after an oak tree that stood outside Gosling’s office; it went by the name Greenlater, and was later renamed Java, from Java coffee, said to be consumed in large quantities by the language’s creators. However, when Java 1.0 was released to the public in 1996, its main focus had shifted to use on the Internet.java language derives much of its syntax from c and c++ but has a simpler object model and fewer low-levelfacilities.

Java is a fully functional, platform independent, programming language it has powerful set of machine independent libraries, including windowing (GUI) libraries.Java applications are typically compiled to byte code (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture.

The most interested thing about java is “write once, run anywhere” (WORA), meaning the code that runs on one platform does not need to be recompiled to run on another.

Why java ?

One characteristic of Java is portability, which means that computer programs written in the Java language must run similarly on any hardware/operating-system platform. This is achieved by compiling the Java language code to an intermediate representation called Java byte code, instead of directly to platform-specific machine code.

Java byte code instructions are analogous to machine code, but are intended to be interpreted by a virtual machine(VM) written specifically for the host hardware. End-users commonly use a Java Runtime Environment (JRE) installed on their own machine for standalone Java applications.

Java is very powerful language but it has its own pros and cons too. so lets discuss some strong and weak points of java.

Pros

  • Free.
  • The syntax is familiar to the programmers that know any other C based language.
  • Java (the platform) has a very large and standard class library, some parts of which are very well written.
  • Java provides a platform for behavioral transfer from one address space to another. This is particularly evident in the dynamic class loading mechanisms of RMI (Remote Method Invocation).
  • Automatic Memory Management implemented by Garbage Collection
  • Explicit Interfaces
  • Improving performance
  • Good portability (certainly better than that of nearly any compiled alternative)
  • Simplified syntax (compared to C++)
  • Language design not committee driven
  • Lots of available code and third-party libraries
  • If you love OOP, the only way to write functions is to make them class methods.
  • Many standard interfaces defined in the standard library, which would have been vendor/OS specific otherwise, helps a lot in achieving portability and ease integration/selection of 3rd party libraries. E.g. JDBC, JMS, JCE, JAI, serial I/O, JAXP, JNDI, etc. Some have correspondence in other languages (e.g. ODBC) but not all.

Cons

  • Performance: Java can be perceived as significantly slower and more memory-consuming than natively compiled languages such as C or C++.
  • Look and feel: The default look and feel of GUI applications written in Java using the Swing toolkit is very different from native applications. It is possible to specify a different look and feel through the pluggable look and feel system of Swing.
  • Single-paradigm language: Java is predominantly a single-paradigm language. However, with the addition of static imports in Java 5.0 the procedural paradigm is better accommodated than in earlier versions of Java.

So , this is all about java from my side. This are some very  basic things about java . I hope it will give all of u a good  start with java.

Future in IT field

It is well known affair that the recession came in the software field and lot of people lost their job due to that. But the latest news came in the news would have given hope in the mind of the computer graduates and the current students that the career opportunity for them will be broad for them.

Why should select the Software companies to work?

The development happened in the software department has changed to the good status nowadays that has made the software companies that the recruiting process will be higher in the next year with 70% increased in the total number. It is happy news for the computer graduates. The outsourcing field Also has developed as well as in the computer field said by the leading outsourcing company NASSCOM.

The quantity of employees to be recruited of top three outsourcing companies of India TCS, Infosys and Wipro is increased. So, the job opportunity for the current computer students and the graduates has increased.

It is expected that the importing rate of the software product of India to be increased to 57 billion American dollars within 2011. This import indicates the demand in the IT field and the same indicates that the situation of firing the employees of the IT department will be changed to the situation of recruiting the new employees for the same field. Many IT companies have started the campus interview culture for recruiting the employees directly from the colleges as before. This culture had given lot of confidence in the mind of the computer students before couple of years. The development in the IT field can be the root cause for the development of India totally. It is a proven truth. 2.3 million Indians are working in the Information Technology field presently. The reasons for the Indians to be in the IT field are, they are adjusting to work with small scale of salary, their fluency in English and their foreign collaborating skill.

What is happening in the IT companies?

The software companies, IT companies and the out sourcing companies are doing the following works most probably,

1.Answering the bank customers queries
2.Law and order activities
3.Engineering works
4.Producing the software products

NASSCOM has declared that they are planned to recruit more than one lakh and 50 thousands of new employees in the next year. This recruitment details can be get from the company web sites of the leading outsourcing companies.

Proof for the development in the IT field:

When we are hearing this good news, the curiosity may peep in our mind what is the reason for this development. The new projects got by the leading companies, the economical development of India. When the new projects are received in huge quantities, the quality policy and the policy of the companies can be changed. The changes will be like reducing the time gap between two projects. These reasons are clearly proving us that the IT companies are climbing the ladder again logically.

New IT park in Karnataka:

The Karnataka government has planned to build a big integrated IT park near the airport of Karnaaka. The construction works for the project has been started at the Veda nalli which is a place in Karnataka.

Industries to be built in the integrated park are,
Information Technology Company
Biotechnology industry
Automobile company
Pharmacy technology industry and
Cement Company

Bangalore has been the destination for the most of the graduates of all over India. There are reasons for that. They are,

Bangalore has been the capital for the Information Technology companies because there is lot of leading IT companies in Bangalore.
The next thing is the climate of Bangalore. It is hard to find people who don’t like the climate of Bangalore.
Bangalore is the city that has the huge number of IT companies in India.

10 Fun Microsoft Facts You Might Not Know

Despite ever-increasing Mac sales, Microsoft still has an undisputed dominance over the computer industry.

With such a vast presence, much has already been written about Microsoft: Its history, its products, even its former CEO Bill Gates. For those itching to know even more, we’ve dug up 10 snippets of info that you might not have heard before.

What experimental musician created the Windows start-up sound? How do they celebrate anniversaries? Does Microsoft have a “pest” problem? Have a read of our Microsoft-themed facts, stats and trivia and let us know your thoughts in the comments below.

1. “Micro-soft’s” First Ever Mention

The first ever mention of “Microsoft” was in a letter from Bill Gates to co-founder Paul Allen in 1975. Gates initially wrote the company name as Micro-soft, which made sense considering it’s a portmanteau of “microcomputer” and “software.”

Losing the hyphen, “Microsoft” was officially registered as a company in November, 1976 in New Mexico where Gates and Allen were working with their first major customer, MITS. Microsoft didn’t move to its current campus in Redmond, Washington until 1986.

The Microsoft logo has changed several times over the years, the current “Pac-Man” logo was introduced in 1987, but previous to that was the “blibbet” logo that’s pictured above. The “blibbet” refers to the stylized “o” and was apparently once the name of a burger served in the Microsoft company cafeteria.

2. Brian Eno Composed “The Microsoft Sound”

Pioneering musician Brian Eno was the musical brains behind Window 95′s start up tune, dubbed “The Microsoft Sound.”

The influential musician, who has worked with the likes of David Bowie and U2, told the San Francisco Chronicle that making such a short piece of music was “funny” and “amazing.” Eno likened the process to “making a tiny little jewel.”

Other musical trivia from the launch of Windows 95 is, of course, the use of The Rolling Stones “Start Me Up” in the ad campaign, while a related Eno fact is that he also composed the music for the computer game Spore.

3. Microsoft’s Fave Food Is Pizza

Although not quite at Google‘s level of snack-tastic, free-for-all wonder, Microsoft does offer free drinks. Over 23 million gratis beverages are downed on the corporate campus each year.

Apparently the top two drinks of choice for Microsoft staffers are milk and OJ. There’s also free candy on the Microsoft campus shuttle.

As far as food goes, Microsoft has around 35 cafeterias (one of which is pictured above) serving around 37,000 people each day. Pizza tops the list of most popular meal.

4. Microsoft Uses Codenames

Ever since the company’s first operating system, Microsoft has worked on its projects under codenames, of which Wikipedia has a long list. Apparently Gates was ready to launch Windows under the name “Interface Manager” before he was persuaded to change it by an employee.

Past codenames include “Longhorn,” “Lone Star,” and “Vienna.” While you might be tempted to add “Mojave,” to that list, it’s actually part of a Microsoft ad campaign. The “Mojave Experiment” was a marketing exercise that battled Vista’s poor PR by presenting the software to new users as a fresh product.

5. The Average “Softie”

The average Microsoft employee, or “Softie” as they call themselves, is a 38-year-old male with the average salary for a developer coming in at $106,000.

Microsoft currently employs 88,180 people who work across 32,404,796 square feet of Microsoft’s premises, over 50,000 of which are U.S.-based. The male to female ratio is very high among Microsoft’s American employees with a staggering 76% male workforce.

6. Microsoft Celebrates Anniversaries With M&Ms

All companies have their little in-house traditions, and Microsoft is no exception. It seems it’s customary for Softies to celebrate their yearly employment anniversaries with candy, and more specifically, M&Ms.

Each anniversary, a Microsoft employee is expected to provide one pound of M&Ms for every year they’ve worked. That means if Bill Gates observed the tradition, he should have turned up with 33 pounds of M&Ms on June 27, 2008.

7. Microsoft’s Stock Has Split Nine Times

Microsoft has split its stock nines times since it went public back in March 1986. Put very, very simply, a company will generally split its stock when its share price becomes too high.

Since Microsoft has had six 2-for-1 splits and three 3-for-1 splits, one original Microsoft share would now be equal to 288 shares today. Interestingly the price of Microsoft’s stock at its initial public offering was $21 a share, at the time of writing a share is now around the $23 mark. One original MSFT share would now be worth over $6,000.

8. Microsoft Has a Huge Art Collection

No, we’re not talking about Clip Art. Microsoft is one of the largest corporate collectors of artworks with over 5,000 contemporary pieces including painting, sculpture, works on paper, photographs, ceramics, studio glass, and multimedia works. Microsoft gathers arts from local artists, up-and-coming artists and big names such asCindy Sherman, Chuck Close and Takashi Murakami.

A large proportion of the works are on display at more than 150 of Microsoft’s many campuses, as the company subscribes to the belief that art in the workplace reduces stress, increases productivity and encourages discussions and expression of opinions.

9. Microsoft Asks Strange Interview Questions

Microsoft has a reputation in the industry for asking off-beat, off-the-wall questions during its job interview. The most oft-quoted question is: “Why is a manhole cover round?” Whether this particular example is genuine, or an urban legend, it’s certainly true that Microsoft employs a very unusual, and forward-thinking interview process. It’s even rumored that companies like Google have since emulated the style.

Rather than plain “Where do you see yourself in five years” type questions, Microsoft is more likely to ask you to solve a logic puzzle or think through a problem like “Design a coffee maker that will be used by astronauts.” Obviously, Microsoft isn’t planning to go into the coffee-in-space industry anytime soon, but the process serves to find candidates that can think creatively.

10. Microsoft Holds Over 10,000 Patents

Microsoft holds over 10,000 patents and files around 3,000 every year, ranking as one of the top five patent owners in the U.S.

Although a large majority of the patents relate to obscure elements of software, the 5,000th and 10,000th were consumer-friendly, easily-understandable ideas. The 5,000th was for tech in Xbox 360 games that lets people “watch” a video game remotely, while the 10,000th was for the Microsoft Surface, linking real-life objects with data and images.

Microsoft also rewards its staff members for securing a new patent. Besides a $1,500 bonus, they get a wooden plaque and a decorative black “cube” that features their name, as well as the title and date of the patent.

BONUS: The Microsoft Campus is Full of Bunnies!

Our very own Jolie O’Dell found a great factoid about the Microsoft Corporate Campus, she gleaned while on a recent visit.

“So, back in the mists of time, some people dumped a bunch of rapidly reproducing pet bunnies — leftovers from kids’ Easter gifts — on a grassy knoll near the MSFT campus,” Jolie said. “The bunnies started doing what bunnies do best, that is, making more bunnies.

At one point, there were so many that MSFT staff had to start catching them and having them spayed and neutered! Nowadays, you’ll still see lots of rabbits hopping around, though. Way cuter than Google’s goats.”

It seems the bunny proliferation has been a long term issue. According to a 1998 Seattle Times article, the “Redmond rabbit problem” does not just affect Microsoft, but Nintendo, Eddie Bauer and other companies in the area.

The problem back then spawned the Redmond Rabbit Coalition group (many members of which are now involved in the current day Evergreen Rabbit Rescue) who campaign for a humane solution to the ongoing pest problem.

20 Strange & Interesting Facts About Microsoft, Google & Apple

strange interesting facts

If you have to pick three companies that take up most of your mindspace, I am sure you would plonk for The Big Three ““ Apple, Microsoft, and Google.

No three companies can be more different, but they affect our lives in the same way.

Microsoft, the oldest of the three, has the iron grip on desktop computing. Apple, next born, is about personal style thanks to iconic products like the Mac and the iPod. Google, the youngest, but arguably the most vivacious of the lot, has a finger in any pie that has to do with the internet (and beyond).

But how well do we know these three that are with us 24×7?
Every great company has a story behind its legend. Strange and interesting facts and anecdotes about behemoths such as these demonstrate that it’s not always about bits, bytes, multi-billion dollar revenues and lawsuits.

Interesting Facts About Google

“We came up with the notion that not all web pages are created equal. People are ““ but not web pages.” ““ Sergey Brin

  • 1. The well known “˜Don’t be evil’ is actually an informal motto of Google. It is a reference to their corporate philosophy which says that you can make money without being evil. It was coined by Paul Buchheit, the man behind Gmail.
  • 2. Sergey Brin and Larry Page didn’t know too much about HTML. That’s why thefirst homepage had a very bare bones design. The simple design caused people to just sit there looking at the screen during initial tests. Test users were actually waiting for the “rest of the page to load”. To solve that particular problem the Google Copyright message was added as a line as an end of page marker.
