Savage moon walkthrough

Savage Moon Walkthrough - PS3 Forums

I think it best that you at least try a few times to complete the missions before going to these walkthroughs as this is a great game and it'd be a shame to miss out on it.

The game is separated into 3 different Moons. Xipe, Ymir and Zeus

XIPE (1st Moon)

Xipe is essentially a tutorial, with the last mission on xipe (Overgar) being the first challenging mission, unfortunately there are no walkthroughs for any of Xipes missions yet, once some go up, I'll make sure to update the OP with them.

lovely website on java interview questions

Java Interview Questions » Java Interview Questions

What if the main method is declared as private?

The program compiles properly but at runtime it will give “Main method not public.” message.

What is meant by pass by reference and pass by value in Java?

Pass by reference means, passing the address itself rather than passing the value. Pass by value means passing a copy of the value.

If you’re overriding the method equals() of an object, which other method you might also consider?

hashCode()

What is Byte Code?

Or

What gives java it’s “write once and run anywhere” nature?

All Java programs are compiled into class files that contain bytecodes. These byte codes can be run in any platform and hence java is said to be platform independent.

Expain the reason for each keyword of public static void main(String args[])?

public- main(..) is the first method called by java environment when a program is executed so it has to accessible from java environment. Hence the access specifier has to be public.

static: Java environment should be able to call this method without creating an instance of the class , so this method must be declared as static.

void: main does not return anything so the return type must be void

The argument String indicates the argument type which is given at the command line and arg is an array for string given during command line.

What are the differences between == and .equals() ?

Or

what is difference between == and equals

Or

Difference between == and equals method

Or

What would you use to compare two String variables - the operator == or the method equals()?

Or

How is it possible for two String objects with identical values not to be equal under the == operator?

The == operator compares two objects to determine if they are the same object in memory i.e. present in the same memory location. It is possible for two String objects to have the same value, but located in different areas of memory.

== compares references while .equals compares contents. The method public boolean equals(Object obj) is provided by the Object class and can be overridden. The default implementation returns true only if the object is compared with itself, which is equivalent to the equality operator == being used to compare aliases to the object. String, BitSet, Date, and File override the equals() method. For two String objects, value equality means that they contain the same character sequence. For the Wrapper classes, value equality means that the primitive values are equal.

public class EqualsTest {

public static void main(String[] args) {

String s1 = “abc”;
String s2 = s1;
String s5 = “abc”;
String s3 = new String(”abc”);
String s4 = new String(”abc”);
System.out.println(”== comparison : ” + (s1 == s5));
System.out.println(”== comparison : ” + (s1 == s2));
System.out.println(”Using equals method : ” + s1.equals(s2));
System.out.println(”== comparison : ” + s3 == s4);
System.out.println(”Using equals method : ” + s3.equals(s4));
}
}

Output
== comparison : true
== comparison : true
Using equals method : true
false
Using equals method : true

What if the static modifier is removed from the signature of the main method?

Or

What if I do not provide the String array as the argument to the method?

Program compiles. But at runtime throws an error “NoSuchMethodError”.

Why oracle Type 4 driver is named as oracle thin driver?

Oracle provides a Type 4 JDBC driver, referred to as the Oracle “thin” driver. This driver includes its own implementation of a TCP/IP version of Oracle’s Net8 written entirely in Java, so it is platform independent, can be downloaded to a browser at runtime, and does not require any Oracle software on the client side. This driver requires a TCP/IP listener on the server side, and the client connection string uses the TCP/IP port address, not the TNSNAMES entry for the database name.

What is the difference between final, finally and finalize? What do you understand by the java final keyword?

Or

What is final, finalize() and finally?

Or

What is finalize() method?

Or

What is the difference between final, finally and finalize?

Or

What does it mean that a class or member is final?

o final - declare constant
o finally - handles exception
o finalize - helps in garbage collection

Variables defined in an interface are implicitly final. A final class can’t be extended i.e., final class may not be subclassed. This is done for security reasons with basic classes like String and Integer. It also allows the compiler to make some optimizations, and makes thread safety a little easier to achieve. A final method can’t be overridden when its class is inherited. You can’t change value of a final variable (is a constant). finalize() method is used just before an object is destroyed and garbage collected. finally, a key word used in exception handling and will be executed whether or not an exception is thrown. For example, closing of open connections is done in the finally method.

What is the Java API?

The Java API is a large collection of ready-made software components that provide many useful capabilities, such as graphical user interface (GUI) widgets.

What is the GregorianCalendar class?

The GregorianCalendar provides support for traditional Western calendars.

What is the ResourceBundle class?

The ResourceBundle class is used to store locale-specific resources that can be loaded by a program to tailor the program’s appearance to the particular locale in which it is being run.

Why there are no global variables in Java?

Global variables are globally accessible. Java does not support globally accessible variables due to following reasons:

* The global variables breaks the referential transparency
* Global variables creates collisions in namespace.

How to convert String to Number in java program?

The valueOf() function of Integer class is is used to convert string to Number. Here is the code example:
String numString = “1000″;
int id=Integer.valueOf(numString).intValue();

What is the SimpleTimeZone class?

The SimpleTimeZone class provides support for a Gregorian calendar.

What is the difference between a while statement and a do statement?

A while statement (pre test) checks at the beginning of a loop to see whether the next loop iteration should occur. A do while statement (post test) checks at the end of a loop to see whether the next iteration of a loop should occur. The do statement will always execute the loop body at least once.

What is the Locale class?

The Locale class is used to tailor a program output to the conventions of a particular geographic, political, or cultural region.

Describe the principles of OOPS.

There are three main principals of oops which are called Polymorphism, Inheritance and Encapsulation.

Explain the Inheritance principle.

Inheritance is the process by which one object acquires the properties of another object. Inheritance allows well-tested procedures to be reused and enables changes to make once and have effect in all relevant places

What is implicit casting?

Implicit casting is the process of simply assigning one entity to another without any transformation guidance to the compiler. This type of casting is not permitted in all kinds of transformations and may not work for all scenarios.

Example

int i = 1000;

long j = i; //Implicit casting

Is sizeof a keyword in java?

The sizeof operator is not a keyword.

What is a native method?

A native method is a method that is implemented in a language other than Java.

In System.out.println(), what is System, out and println?

System is a predefined final class, out is a PrintStream object and println is a built-in overloaded method in the out object.

What are Encapsulation, Inheritance and Polymorphism

Or

Explain the Polymorphism principle. Explain the different forms of Polymorphism.

Polymorphism in simple terms means one name many forms. Polymorphism enables one entity to be used as a general category for different types of actions. The specific action is determined by the exact nature of the situation.

Polymorphism exists in three distinct forms in Java:
• Method overloading
• Method overriding through inheritance
• Method overriding through the Java interface

What is explicit casting?

Explicit casting in the process in which the complier are specifically informed to about transforming the object.

Example

long i = 700.20;

int j = (int) i; //Explicit casting

What is the Java Virtual Machine (JVM)?

The Java Virtual Machine is software that can be ported onto various hardware-based platforms

What do you understand by downcasting?

The process of Downcasting refers to the casting from a general to a more specific type, i.e. casting down the hierarchy

What are Java Access Specifiers?

Or

What is the difference between public, private, protected and default Access Specifiers?

Or

What are different types of access modifiers?

Access specifiers are keywords that determine the type of access to the member of a class. These keywords are for allowing
privileges to parts of a program such as functions and variables. These are:
• Public : accessible to all classes
• Protected : accessible to the classes within the same package and any subclasses.
• Private : accessible only to the class to which they belong
• Default : accessible to the class to which they belong and to subclasses within the same package

Which class is the superclass of every class?

Object.

Name primitive Java types.

The 8 primitive types are byte, char, short, int, long, float, double, and boolean.

What is the difference between static and non-static variables?

Or

What are class variables?

Or

What is static in java?

Or

What is a static method?

A static variable is associated with the class as a whole rather than with specific instances of a class. Each object will share a common copy of the static variables i.e. there is only one copy per class, no matter how many objects are created from it. Class variables or static variables are declared with the static keyword in a class. These are declared outside a class and stored in static memory. Class variables are mostly used for constants. Static variables are always called by the class name. This variable is created when the program starts and gets destroyed when the programs stops. The scope of the class variable is same an instance variable. Its initial value is same as instance variable and gets a default value when its not initialized corresponding to the data type. Similarly, a static method is a method that belongs to the class rather than any object of the class and doesn’t apply to an object or even require that any objects of the class have been instantiated.
Static methods are implicitly final, because overriding is done based on the type of the object, and static methods are attached to a class, not an object. A static method in a superclass can be shadowed by another static method in a subclass, as long as the original method was not declared final. However, you can’t override a static method with a non-static method. In other words, you can’t change a static method into an instance method in a subclass.

Non-static variables take on unique values with each object instance.

What is the difference between the boolean & operator and the && operator?

If an expression involving the boolean & operator is evaluated, both operands are evaluated, whereas the && operator is a short cut operator. When an expression involving the && operator is evaluated, the first operand is evaluated. If the first operand returns a value of true then the second operand is evaluated. If the first operand evaluates to false, the evaluation of the second operand is skipped.

How does Java handle integer overflows and underflows?

It uses those low order bytes of the result that can fit into the size of the type allowed by the operation.

What if I write static public void instead of public static void?

Program compiles and runs properly.

What is the difference between declaring a variable and defining a variable?

In declaration we only mention the type of the variable and its name without initializing it. Defining means declaration + initialization. E.g. String s; is just a declaration while String s = new String (”bob”); Or String s = “bob”; are both definitions.

What type of parameter passing does Java support?

In Java the arguments (primitives and objects) are always passed by value. With objects, the object reference itself is passed by value and so both the original reference and parameter copy both refer to the same object.

Explain the Encapsulation principle.

Encapsulation is a process of binding or wrapping the data and the codes that operates on the data into a single entity. This keeps the data safe from outside interface and misuse. Objects allow procedures to be encapsulated with their data to reduce potential interference. One way to think about encapsulation is as a protective wrapper that prevents code and data from being arbitrarily accessed by other code defined outside the wrapper.

What do you understand by a variable?

Variable is a named memory location that can be easily referred in the program. The variable is used to hold the data and it can be changed during the course of the execution of the program.

What do you understand by numeric promotion?

The Numeric promotion is the conversion of a smaller numeric type to a larger numeric type, so that integral and floating-point operations may take place. In the numerical promotion process the byte, char, and short values are converted to int values. The int values are also converted to long values, if necessary. The long and float values are converted to double values, as required.

What do you understand by casting in java language? What are the types of casting?

The process of converting one data type to another is called Casting. There are two types of casting in Java; these are implicit casting and explicit casting.

What is the first argument of the String array in main method?

The String array is empty. It does not have any element. This is unlike C/C++ where the first element by default is the program name. If we do not provide any arguments on the command line, then the String array of main method will be empty but not null.

How can one prove that the array is not null but empty?

Print array.length. It will print 0. That means it is empty. But if it would have been null then it would have thrown a NullPointerException on attempting to print array.length.

Can an application have multiple classes having main method?

Yes. While starting the application we mention the class name to be run. The JVM will look for the main method only in the class whose name you have mentioned. Hence there is not conflict amongst the multiple classes having main method.

When is static variable loaded? Is it at compile time or runtime? When exactly a static block is loaded in Java?

Static variable are loaded when classloader brings the class to the JVM. It is not necessary that an object has to be created. Static variables will be allocated memory space when they have been loaded. The code in a static block is loaded/executed only once i.e. when the class is first initialized. A class can have any number of static blocks. Static block is not member of a class, they do not have a return statement and they cannot be called directly. Cannot contain this or super. They are primarily used to initialize static fields.

Can I have multiple main methods in the same class?

We can have multiple overloaded main methods but there can be only one main method with the following signature :

public static void main(String[] args) {}

No the program fails to compile. The compiler says that the main method is already defined in the class.

Explain working of Java Virtual Machine (JVM)?

JVM is an abstract computing machine like any other real computing machine which first converts .java file into .class file by using Compiler (.class is nothing but byte code file.) and Interpreter reads byte codes.

How can I swap two variables without using a third variable?

Add two variables and assign the value into First variable. Subtract the Second value with the result Value. and assign to Second variable. Subtract the Result of First Variable With Result of Second Variable and Assign to First Variable. Example:

int a=5,b=10;a=a+b; b=a-b; a=a-b;

An other approach to the same question

You use an XOR swap.

for example:

int a = 5; int b = 10;
a = a ^ b;
b = a ^ b;
a = a ^ b;

What is data encapsulation?

Encapsulation may be used by creating ‘get’ and ’set’ methods in a class (JAVABEAN) which are used to access the fields of the object. Typically the fields are made private while the get and set methods are public. Encapsulation can be used to validate the data that is to be stored, to do calculations on data that is stored in a field or fields, or for use in introspection (often the case when using javabeans in Struts, for instance). Wrapping of data and function into a single unit is called as data encapsulation. Encapsulation is nothing but wrapping up the data and associated methods into a single unit in such a way that data can be accessed with the help of associated methods. Encapsulation provides data security. It is nothing but data hiding.

What is reflection API? How are they implemented?

Reflection is the process of introspecting the features and state of a class at runtime and dynamically manipulate at run time. This is supported using Reflection API with built-in classes like Class, Method, Fields, Constructors etc. Example: Using Java Reflection API we can get the class name, by using the getName method.

Does JVM maintain a cache by itself? Does the JVM allocate objects in heap? Is this the OS heap or the heap maintained by the JVM? Why

Yes, the JVM maintains a cache by itself. It creates the Objects on the HEAP, but references to those objects are on the STACK.

What is phantom memory?

Phantom memory is false memory. Memory that does not exist in reality.

Can a method be static and synchronized?

A static method can be synchronized. If you do so, the JVM will obtain a lock on the java.lang.
Class instance associated with the object. It is similar to saying:

synchronized(XYZ.class) {

}

What is difference between String and StringTokenizer?

A StringTokenizer is utility class used to break up string.

Example:

StringTokenizer st = new StringTokenizer(”Hello World”);

while (st.hasMoreTokens()) {

System.out.println(st.nextToken());

}

Output:

Hello

World

cassandra 0.4.0 is out

Mailing list archives

adies and gentlemen, I give you Cassandra 0.4.0. It's hard to imagine that it has only been 2 months since our very first release[1]; an impressive amount of progress has been made. For example: * Nodes can now scale to billions of keys instead of millions. * There is support for multiple keyspaces (formerly known as tables). * You can now create snapshots * A new bootstrap feature for adding nodes to a running cluster * A new multiget API * Numerous improvements to the Thrift API And many, many, more. In fact, don't take my word for it, check out the changelog[2], or the 176 closed Jira issues (176!)[3]. Many thanks to all those that contributed patches, reviewed, tested, documented, or counseled.

Pretty cool.

On my macbook pro, I got about 2400 inserts / s with cassandra 0.4.0. I was not able to get a multinode setup on my ec2 enviroment.

recommended use for hbase htable and cached hbase configuration

RE: HBase Client Concerns

Many thanks again. I think I'll go initially with cached HBaseConfiguration and one new HTable instance per request thread and accept the resulting slowness overhead per request. When the HTablePool pause/retry param issue is resolved, I can switch to that. To workaround the problem of restarting the client app when the HBase servers are restarted, I can then maybe wrap HTablePool into a class which essentially clears the pool cache [forcing instantiating a new HTable] when any of the HTablePool.getTable() client calls time out, so the client app need not be restarted... Cheers,

mysql benchmark on mac

Ran a quick benchmark on my macbook pro :P

1,000,000 rows inserted serially.
596023 ms taken.
1677 rows inserted /s.

MySQL is faster on my localhost than memcacheDB.

MemcacheDB benchmark

On ubuntu amazon ec2 large instance - using java and spy memcache client.
Ran memcachedb with command

memcachedb -m 2064 -p 11211 -u memcachedb -l 127.0.0.1 -b 22000

Results - 10,000 puts of 140 characters in 22143 ms.
Roughly..
451 puts / s.

inserted 140 characters with a 5 character key.

key value store	time taken to insert 10,000 records	MB taken for storage	inserts /s
memcachedb	22143 ms	1300 MB	451 puts / s

Note - I had to add an artificial 1 ms delay after every insert. The memcache client would throw a queue size exception.
If time took 12143 ms, we would get roughly.

900 puts / s

How to delete old time machine backups

How to Delete Individual Backups from Apple Time Machine « Psychohistory

One of those menu items is “Delete Backup”.

So, to delete a full backup, you just do the following:

1. Navigate to the date you want to delete. In my case, I wanted to delete my oldest backup, from 1/30/2008.
2. Navigate in the Finder window to your overall machine. In my case, it’s called “Powersmash G5″, where I have 2 internal drives that are backed up.
3. Select the “Gear” menu, and select “Delete Backup”
4. Enter the admin password for the Finder, if it asks.

My guess is that Apple wasn’t trying to make this hard - they are just suffering from a non-standard interface, and then an overloading of that “gears” menu, which I’m sure is theoretically supposed to be a “contextual menu”. For me, a menu that showed on on right-click of either the finder window itself or the Time Machine backup marker on the right would have been more obvious to me.

Hope this tip is useful to someone. It sure helped me today.

how to create a patch file! useful stiff

» How to create and apply a patch with Subversion Ariejan.net

t’s been a while since I posted something new on the use of Subversion. I’ve been working with the tool a lot, and I’ve found that patches are a great way to communicate code changes.

For those of you who are still learning, let me first explain what a patch is. A patch is a text file that contains the alteration that were made to a specific file. It includes the lines that have been removed and the lines that have been added. In short, if you have a ruby script and edited it, you could create a patch file, containing the changes you’ve made.

Why is this useful? You could check in your changes to your repository directly. True, but there are cases that you don’t have write access to the repository. For example, if you wanted to contribute code changes to Acts As Exportable, you should create a new ticket and attach a patch file. I will then review your changes before I apply them to the code and commit them to the repository.

So, how do you go about creating a patch file and how do you later apply it to your source?
Creating a patch file

Creating a patch file is really easy. First, check out the most recent version of the code from Subversion using the ‘checkout’ command.

Make your changes.

Then, in the root the project run the following command. It will store the patch file in your home directory. Make sure to give it meaningful filename.

svn diff > ~/fix_ugly_bug.diff

The file has the .diff extention, which stands for differences. This extension is recognized by many text editors and enables ’syntax highlighting’ automatically. (Give it a try with TextMate and you’ll know what I mean.)

You can send the diff-file to the author of the project by email, or you can create a ticket in Trac and add it as an attachment. The author will review the changes you made and possibly apply them to the source.
Applying a patch

You should never apply patches from any person other than your development team without first reading through the changes, apply them locally and test your application and then commit them. Patches can not only include bug fixes, but also alterations to create back doors or add other exploits to your code.

Always read through a patch before applying it!

When you are sure the patch will bring no harm to you, your application or your customers, go ahead an apply it to your working copy. Here, I assume that you downloaded the patch file we previously generated, and placed it in your home directory. In the root of your application now run:

patch -p0 -i ~/fix_ugly_bug.diff

This will apply all the changes in the patch to your source. The -p0 option makes sure that all files can be found correctly (this has to do with something called ‘zero directories’, I won’t get into that right now). The -i option tells ‘patch’ what to use as input, in this case the ‘fix_ugly_bug.diff’ file in your home directory.

With the code changes in place, run your tests and make sure everything works as expected. If it does, commit your changes and celebrate with a cup of coffee.

How to setup Streaming for media - xbox 360, xbox, ps3, wii - movies, videos, music, pictures

How to set up a streaming media network | News | TechRadar UK

Software streaming

What if you only want to stream to a laptop or another PC? All you need is some software.

A dedicated media streamer is all well and good, but most of them cost in the the region of £100 to £200, which certainly doesn't make them the cheapest solution. If you want to view pictures or listen to audio on your laptop, or another PC in the house, then all you need to do is set up a shared folder, then browse to it on the network and open the files in the same way that you would do on the local machine.

As long as your network has the range, taking your laptop into the garden and plugging in some external speakers, is possibly the simplest way of getting music to your garden party. However, Windows networking is notoriously fickle, especially if you are mixing operating systems, so a dedicated software solution may be better.

Windows Media Player 11 is built into Windows Vista and can be downloaded for XP and once set up for sharing, WMP11 turns your PC with the media library into a media server. A Vista laptop will usually automatically detect a shared library and ask whether you want to connect to it. You can also share your iTunes library, and then access it from another PC or laptop running iTunes.

However, one of our favourite solutions for sharing media is Orb, which enables you to share music, video, pictures and documents, not just across your local network, but across the internet as well. It's a great way to listen to your music collection when you're at work, a friend's house or anywhere else that you can get a respectible internet connection.

Not only is Orb free, but you can use it to stream your files to the Xbox 360, Playstation 3, Nintendo Wii and even some handhelds, like the iPod touch and mobile phones. An alternative is TVersity, which will also work with any internet connected device that has a web browser that supports Flash.

Xbox 360

Got an Xbox 360? Then there's no need to buy yourself a separate media streamer. It's not just a games console you know.

While the Xbox 360 might have enjoyed phenomenal success as a games console, it has some other rather nifty tricks up its sleeve. Although the Xbox 360 has no built-in wireless, it does have an Ethernet connection, and there's a wireless adaptor available, although it does only use the 802.11g standard.

The Xbox 360 is designed to connect to a PC running Windows Media Center, and if you have a PC running that (either Vista, or Windows XP MCE) then the system works very well. The Xbox's interface is pretty much the same as Media Centre and it is slick and easy to use. If you don't have a PC running any form of media centre, then you can use Windows Media Player 11 instead.

Once sharing has been setup, the Xbox is able to connect and browse the folders in much the same way as any other media streamer. It's not nearly as good as the Media Centre Interface, and it has a nasty habit of failing to connect to our shared library, but when it works, it's pretty good. Since Microsoft updated the firmware, the Xbox is able to play Xvid and DivX content, but cannot play some other file formats. In this case, you can use a program called Tversity which can transcode incompatible file formats on the fly, into ones the Xbox can play.

Using Tversity, the Xbox can even stream live video feeds, which is a pretty unique feature. An alternative is to use Orb, which enables you to view almost any content you wish to share, by using folder sharing. You may not think that the Xbox is a natural contender for streaming audio and video to your TV and stereo, but after testing a large number of media streamers, we have to say the Xbox is actually one of the best devices we've ever used, especially when you decide to use it with Media Centre.

Playstation 3

Playstation 3 owners rejoice! You too can stream all your media with ease. Don't let the Microsoft fanboys have all the fun.

The last few months has seen a number of significant updates released for the PS3, all of which have increased the console's functionality. Like the Xbox 360, you can use Windows Media Player 11 to share your media and view it using the PS3. However, just as with the Xbox, Windows Media is a temperamental beast and can cause irrational anger and the urge to chuck the controller at the TV when it stops working properly.

In our expericene, you are much better off using Tversity, which also works with the Xbox. However, you will need to configure your router to make it work correctly, but it's a two minute job and is pretty simple. First of all download Tversity and leave all the settings at the defaults.

You may want to download FFDShow and any other additional codecs you use regularly. You'll need to change your Windows or third-party firewall settings to allow mediaserver.exe, which is found in the Tversity folder, access to the internet. Configure your router, by typing its IP address into your web browser's address bar, it's usually 192.168.0.1, but if it isn't, run ipconfig from a command prompt to determine your PC's IP address and use the first IP in that range for your router.

Within your router's control panel you find that you'll need to edit the section for virtual servers or port forwarding, and allow access to port 41952. In addition, just as with the Xbox, you can use Orb with the PS3, although instead of using the folder sharing, you use the built-in browser and navigate to mycast.orb.com.
