Linux Vs Windows

2013-08-19T02:35:00.000-07:00

Topics	Linux	Windows
Price	The majority of Linux variants are available for free or at a much lower price than Microsoft Windows.	Microsoft Windows can run between $50.00 - $150.00 US dollars per each license copy.
Ease	Although the majority Linux variants have improved dramatically in ease of use, Windows is still much easier to use for most computer users because of the familiarity of Windows and because it's more likely they are using a Windows computer at home, in school, or at the office.	Microsoft has made several advancements and changes that have made it a much easier to use operating system, and although arguably it may not be the easiest operating system, it is still Easier than Linux.
Reliability	The majority of Linux variants and versions are notoriously reliable and can often run for months and years without needing to be rebooted.	Although Microsoft Windows has made great improvements in reliability over the last few versions of Windows, it still cannot match the reliability of Linux.
Software	Linux has a large variety of available software programs, utilities, and games. However, Windows has a much larger selection of available software.	Because of the large amount of Microsoft Windows users, there is a much larger selection of available software programs, utilities, and games for Windows.
Software Cost	Many of the available software programs, utilities, and games available on Linux are freeware or open source. Even such complex programs such as Gimp, OpenOffice, StarOffice, and wine are available for free or at a low cost.	Although Windows does have software programs, utilities, and games for free, the majority of the programs will cost anywhere between $20.00 - $200.00+ US dollars per copy.
Hardware	Although hardware manufacturers have made great advancements in supporting Linux it still will not support most hardware devices. However, for the hardware devices that have driver support they will usually work in all versions of Linux.	Because of the amount of Microsoft Windows users and the broader driver support, Windows has a much larger support for hardware devices and almost all hardware manufacturers will support their products in Microsoft Windows.
Security	Linux is and has always been a very secure operating system. Although it still can be attacked when compared to Windows, it much more secure.	Although Microsoft has made great improvements over the years with security on their operating system, their operating system continues to be the most vulnerable to viruses and other attacks.
Open Source	Many of the Linux variants and many Linux programs are open source and enable users to customize or modify the code however they wish to.	Microsoft Windows is not open source and the majority of Windows programs are not open source.
Support	Although it may be more difficult to find users familiar with all Linux variants, there are vast amounts of available online documentation and help, available books, and support available for Linux.	Microsoft Windows includes its own help section, has vast amount of available online documentation and help, as well as books on each of the versions of Windows.

Windows 8.1 Set to bring back the Start button

2013-05-21T22:26:00.000-07:00

Microsoft is preparing to revive the traditional Start button it killed with Windows 8. Sources familiar with Microsoft's plans have revealed to The Verge that Windows 8.1 will include the return of the Start button. We understand that the button will act as a method to simply access the Start Screen, and will not include the traditional Start Menu. The button is said to look near-identical to the existing Windows flag used in the Charm bar.

MICROSOFT CHANGES ITS MIND

Microsoft's change of heart follows another recent planned change for Windows 8.1: a boot to desktop option. We understand Microsoft will add an option to allow users to boot directly to the traditional desktop environment in future builds of the upcoming Windows 8 upgrade. Most internal builds of Windows 8.1 do not include the Start button or boot to desktop options, but Microsoft is said to be planning how to add these into the operating system. ZDNet's Mary Jo Foley previously reported on Microsoft's plans to bring back the Start button and a boot to desktop option.

The death of the traditional Start button in Windows 8 was one of a number of controversial changes introduced with Microsoft's latest operating system. In our review of Windows 8 we called the new navigation changes "a steep learning curve," and feedback on the Start button removal has been mixed. 1.5 million downloads of Pokki, a Start Menu replacement, and other similar tools suggest that Windows 8 users still want the Start button and Start Menu. Microsoft explained away its removal using data it gathered from the company's Customer Experience Improvement Program, but we understand the return in Windows 8.1 is due to customer feedback. We may see the Start button return in the upcoming Windows 8.1 Public Preview, if not expect to see it in the final version due later this year.

Windows 8 Advantages and Disadvantages

2013-05-20T05:25:00.001-07:00

Party claim if microsoft windows 8 better than that of its predecessor Windows XP and also seven. The user will feel a different experience for Windows 8 can be operated using your fingers, with a record of laptop, tablet, or smartphone you already support touchscreen technology.

Lack Windows 8

No Start Button

The lack of perceived make start button windows 8 users find it difficult to start the work. Although there has been a search box, where the start button as crucial to an operating system.

Difficult Switching Between Screen
With no alt + tab function put through difficulties when they want to switch from one application to another. But instead, there is a Metro UI that allows us to drag and drop application that is running.
Those are some of the advantages and disadvantages of windows 8, may be able to add your insights and be a reference before deciding to move to the operating system Windows 8.

My Top Ten Tips on how to become a Rockstar Programmer

2013-05-20T04:24:00.001-07:00

#1 Do development on a fast computer

Wicked fast even. Compiling should take at most a couple of seconds so that you do this often. In fact what is most important is how long it takes from you hitting that Run Project short key until your application shows up. The lesser the time the more you will run the application and the more keen you will be to try new things, which is how you learn. If running takes too long you will go for, not safer, but code you know to work, and you will evolve more slowly. A good advice is also to keep a crappy computer around for testing. Your GUI might feel snappy on your super fast developer monster machine, but your customers might not be so lucky as to have one of those.

#2 Use a big TFT screen

Code is talking to you in more than characters. With a bigger screen you will get more overview and this helps your right side brain into the game. You will see patterns more clearly and you can see the structure of a whole method and not just parts of it. You should have such a big screen that your methods will fit, in most cases, on one page. Eyes move fast, editor scroll panes do not. I use a 30 inch Apple CinemaDisplay and a 20 inch Dell rotated 90 degrees as a second debugging monitor.

#3 Learn your IDE

It matters less what IDE you use, today they are all above the good enough bar. Be ashamed every time you do something in a way you know you can do faster another way. Learn a new feature of your IDE until you have learned them all, or at least learned enough. Use short keys but don't over exaggerate. Be super lazy and create short cuts for everything you do. All to keep down the waiting time and minimizing the most important code-to-show time.

#4 Don't learn APIs too well

The APIs might change and/or you might start to use another API. Learn how to find information about the APIs really fast. Use your IDE for this where appropriate. Use JavaDoc for your own code and mount the JavaDocs in your projects for imported APIs. Knowing how to find information is good for everything, storing APIs in brainRAM is bound to get old. If for instance you don't use some sort of parameter help/completion you have a long walk ahead.

#5 Write smart cool compressed code constructs

And test them thoroughly! You will learn what works and what don't. You will evolve, not to use the smartest and coolest code, but in terms of knowing that smart code constructs is seldom the way of the rock star programmer, other than for showing off. Less code, in a smart way, means less to maintain. Over-smart code that is just for show will make your fellow code maintainers put "fart bags" on your chair just when the new super-hottie from the Rocket Scientists Department comes over to ask you a question (which would be a bad thing).

#6 Read books

You might be good at what you do, but knowing only that, whatever it may be, is seldom enough to really shine. Knowing enough about more fields than the field you are about to shine in is golden. Take for instance a GUI coder that knows nothing about databases. He might be almost useless since he can't interact with the guy doing the backing store, and so on. It takes as much effort to be 90% good in five fields than to be 99% good one one.

#7 Go back and enhance your old code

Not that it is sound from an economical point of view but because you learn oodles of things reading you own crap, which old code always is. Code gets rotten after a couple of years, it really does, since you evolve. If you can't find bad things in your old code you either already are a rock star programmer, or maybe more probable, hasn't evolved much lately.

#8 Eat your own dog food!

If you create APIs, create some applications using that API. If you create applications, ask your friends/wife(s)/husband(s)/children to try it. Don't say you did it; say that your crappy no-good overpaid work mate did it, so you get some honest feedback. Honest feedback is golden.

#9 Don't ask people for advice

Learn how to get that answer yourself instead, it is way more useful. Finding out how to get information about something is a value in itself and may pay you back more than the solution to the problem in the first place. Ask only if you must or if the question in itself is more a discussion and you are actually spreading information. Of course you shouldn't take this too literally, but I see lots of people asking pointless questions they could have found out faster by ten seconds of googling.

#10 Do micro benchmarks

But know that they are useless for almost all purposes in the real world. It will increase your knowledge about performance though, and next time you have a higher probability of choosing the fastest construct for new code. Don't do premature code optimization but learn how to write fast code from the start, without sacrificing readability.

#11 And last...

Eat right, exercise more, don't drink too much coffee, and all that other crap that matter more than you think, but you won't do because I said so.

5 Most Usefull Java Best Practice Quotes for Java Developers

2012-05-18T16:12:00.004-07:00

Quote 1: Avoid creating unnecessary objects and always prefer to do Lazy Initialization

Object creation in Java is one of the most expensive operation in terms of memory utilization and performance impact. It is thus advisable to create or initialize an object only when it is required in the code.

public class Countries {

    private List countries;

    public List getCountries() {

        //initialize only when required

        if(null == countries) {

            countries = new ArrayList();

        }

        return countries;

    }

} 

Quote 2: Never make an instance fields of class public
Making
 a class field public can cause lot of issues in a program. For instance
 you may have a class called MyCalender. This class contains an array of
 String weekdays. You may have assume that this array will always 
contain 7 names of weekdays. But as this array is public, it may be 
accessed by anyone. Someone by mistake also may change the value and 
insert a bug!

public class MyCalender {

    public String[] weekdays =

        {"Sun", "Mon", "Tue", "Thu", "Fri", "Sat", "Sun"};

    //some code 

}

Best approach as many of you already know is to always make the field private and add a getter method to access the elements.

private String[] weekdays =

    {"Sun", "Mon", "Tue", "Thu", "Fri", "Sat", "Sun"};

public String[] getWeekdays() {

    return weekdays;

}

But
 writing getter method does not exactly solve our problem. The array is 
still accessible. Best way to make it unmodifiable is to return a clone 
of array instead of array itself. Thus the getter method will be changed
 to.

public String[] getWeekdays() {  

  return weekdays.clone();

}

Quote 3: Always try to minimize Mutability of a class
Making a
 class immutable is to make it unmodifiable. The information the class 
preserve will stay as it is through out the lifetime of the class. 
Immutable classes are simple, they are easy to manage. They are thread 
safe. They makes great building blocks for other objects.

However 
creating immutable objects can hit performance of an app. So always 
choose wisely if you want your class to be immutable or not. Always try 
to make a small class with less fields immutable.

To make a class immutable you can define its all constructors private and then create a public static method
 to initialize and object and return it.

public class Employee {

    private String firstName;

    private String lastName;

    //private default constructor

    private Employee(String firstName, String lastName) {

        this.firstName = firstName;

        this.lastName = lastName;

    }

    public static Employee valueOf (String firstName, String lastName) {

        return new Employee(firstName, lastName);

    }

Quote 4: Try to prefer Interfaces instead of Abstract classes
First
 you can not inherit multiple classes in Java but you can definitely 
implements multiple interfaces. Its very easy to change the 
implementation of an existing class and add implementation of one more 
interface rather then changing full hierarchy of class.

Again if 
you are 100% sure what methods an interface will have, then only start 
coding that interface. As it is very difficult to add a new method in an
 existing interface without breaking the code that has already 
implemented it. On contrary a new method can be easily added in Abstract
 class without breaking existing functionality.

Quote 5: Always try to limit the scope of Local variable
Local
 variables are great. But sometimes we may insert some bugs due to copy 
paste of old code. Minimizing the scope of a local variable makes code 
more readable, less error prone and also improves the maintainability of
 the code.

Thus, declare a variable only when needed just before its use.

Always initialize a local variable upon its declaration. If not possible at least make the local instance assigned null value.

Java or J2EE : the Name Matters

2012-05-17T13:33:00.000-07:00

10 years ago, when we were decided to use Java technology to create a new application,
for use at Amway Corp; we thought it was sufficient to say, "We are using Java!".
We were wrong...
We quickly realized that there was Java 2 Standard Edition and there was Java 2 Enterprise Edition.
Since we were architecting our application to run in an application server-based environment,
we concluded that we would be using Java 2 SE and Java 2 EE.
We were wrong again...
Further investigation told us that there were parts of the Java 2 SE API that we could not use
in our application.
For example, we could (or should) not use any thread control (util.concurrent package) portions of
Java 2 SE because the application server would handle thread control for the application.
Since our basic User Interface would be a web browser, any screen rendering (awt, swing packages)
portions of Java 2 SE were off-limits as well.
We finally decided to say that we are using J2EE technologies with the Java programming language.
That should have settled things.
We were wrong again...
As our project progressed in those first few months, we became known as the "Java group".
Many of the other IT groups, at Amway Corp, thought we were doing client-side Java development.
They thought we were creating easy, simple applications with our "cute" Java tools.
We felt we had to correct this misconception. So back to the names.
The final position on the names was the following:
We are the "J2EE group".
We do not develop Java applications, we develop J2EE applications.
Our application is not client-based, it is server-based.
So 10 years later, how did things work out?
Even though J2EE is now JEE, we still use the J2EE acronym. We really like the way it sounds. J2EE!
Other IT groups still call us the "Java group". But with 1 million lines of code in
production, no one thinks our application is simple or cute.
So what you use for a name really does matter.
To this day, I still find myself telling someone at Amway, "We don't do Java... We do J2EE!!!"
