How to install Windows 10 in a virtual machine ?

After last week’s Windows 10 briefing, a brand new build of the Windows 10 Technical Preview was released publicly. Anyone can sign-up for the Windows Insider program and get a taste of Windows 10. Of course, pre-release builds should never be used as a primary OS, so today I’ll walk you through how to run the Windows 10 Technical Preview in a virtual machine.

Under normal circumstances I would do this walkthrough with Oracle’s VirtualBox. It’s free, open source, and works on just about any operating system. Sadly, the drivers appear to be broken for the time being. I couldn’t get sound or networking to work at all, and the screen resolution is severely limited. A quick peek at the community forums shows that other people are having the exact same problems, so hold off using VirtualBox for Windows 10 until these major kinks get worked out.

Instead, I’ll be using the free VMware Player application. It works like a charm, but it’s only available for Windows and Linux. VMware does offer premium virtualization solutions for OS X, but that’s a large investment just to test a preview build of Windows. I can’t recommend dropping $70 if this is all you’ll be using it for. With all that in mind, let’s jump in.

11

1. Download the Windows 10 ISO

First off, head over to the Windows Insider site, and sign up. Once you’ve agree to the terms of service, proceed to the download page, and pick which disc image you want to download. For the purposes of this walkthrough, I’m using the 32-bit English ISO, but go with whatever works for your set-up.

22

2. Create a new virtual machine

Now, you need to install VMware Player. Head to the download page, pick which platform you want, and complete the installation.

Once the application is installed, launch it, and navigate to Player > File > New Virtual Machine to get this party started.
33

3. Find your Windows 10 ISO

Next, you need to tell VMware Player where to find the Windows 10 ISO. Select the second option labeled “Installer disc image file (ISO),” and then navigate to the Windows 10 ISO you downloaded earlier.
44

4. Choose your save location

Pick out a name for this virtual machine, and then select where you’d like it to be saved.

55

5. Configure your virtual hard disk

On this screen, you need to choose how big you want your virtual disk to be. 60GB is the default, but you can increase it as needed. Just make sure you have enough free space on your actual hard disk.

By default, VMware Player will split your virtual disk over multiple files, and I recommend leaving it that way. Unless you have a specific reason to change it, keep it as is.
66

6. Customize your hardware configuration

Next, click the “Customize Hardware” button before we finish the initial set-up.

77

7. Allocate RAM

The default here is 1GB, but more would be better. I have 16GB of RAM in my machine, so I decided 4GB was an appropriate allocation for this virtual machine. Follow the guide on the right of the screen, and don’t go above the maximum recommended memory. If you outstrip what’s available, you’ll end up paging to the hard disk, and making everything slow to a crawl.

88

8. Configure the CPU

Switch over to the CPU tab, and choose how many cores you want to dedicate to this machine. One is the default, and that’s probably a safe starting point. My machine has four cores, so I usually end up bumping it to two cores for virtual machines, but your milage may vary.

Now, take a look at the button labeled “Virtualize Intel VT-x/EPT or AMD-V/RVI.” If you’re using the 64-bit version of Windows 10, this is mandatory. Of course, your CPU needs to support this functionality, so use this tool from Microsoft to verify that it will work with your processor.

99

9. Begin the installation

Close out of the hardware configuration, and “Finish” the initial set-up. Now, boot up your virtual machine, and install Windows 10 just like you would normally.
1010

10. Install the VMware tools

Once Windows 10 has finally booted up, navigate to Player > Manage > Install VMware Tools. It will mount a virtual DVD, and pop up a notification in the bottom right. Navigate to the disc in Windows Explorer, launch the appropriate executable, and follow the on-screen instructions.

Note: If you don’t already have the VMware tools on your PC, follow this process to download them.
1111

11. Reboot your virtual machine

When it’s finished installing, reboot your virtual machine.

1212

And you’ve virtualized Windows 10!

Finally, your Windows 10 installation is ready to use — even in fullscreen mode. Poke around, download the OS updates, and enjoy the cutting edge of Windows. And when something inevitably breaks, it won’t matter. This is just a virtual machine, so toss it, and start over.

How to create an immutable object in Java?

An immutable class is one whose state can not be changed once created. Here, state of object essentially means the values stored in instance variable in class whether they are primitive types or reference types.

To make a class immutable, below steps needs to be followed:

  • Don’t provide “setter” methods or methods that modify fields or objects referred to by fields. Setter methods are meant to change the state of object and this is what we want to prevent here.
  • Make all fields final and private. Fields declared private will not be accessible outside the class and making them final will ensure the even accidentally you can not change them.
  • Don’t allow subclasses to override methods. The simplest way to do this is to declare the class as final. Final classes in java can not be overridden.
  • Always remember that your instance variables will be either mutable or immutable. Identify them and return new objects with copied content for all mutable objects (object references). Immutable variables (primitive types) can be returned safely without extra effort.

What is the difference between C++ and Java ?

Both C++ and Java use similar syntax and are Object Oriented, but:

  • Java does not support pointers. Pointers are inherently tricky to use and troublesome.
  • Java does not support multiple inheritances because it causes more problems than it solves. Instead Java supports multiple interface inheritance, which allows an object to inherit many method signatures from different interfaces with the condition that the inheriting object must implement those inherited methods. The multiple interface inheritance also allows an object to behave polymorphically on those methods.
  • Java does not support destructors but rather adds a finalize() method. Finalize methods are invoked by the garbage collector prior to reclaiming the memory occupied by the object, which has the finalize() method. This means you do not know when the objects are going to be finalized. Avoid using finalize() method to release non-memory resources like file handles, sockets, database connections etc because Java has only a finite number of these resources and you do not know when the garbage collection is going to kick in to release these resources through the finalize() method.
  • Java does not include structures or unions because the traditional data structures are implemented as an object oriented framework
  • All the code in Java program is encapsulated within classes therefore Java does not have global variables or functions.
  • C++ requires explicit memory management, while Java includes automatic garbage collection.

Linux ‘Locate’ Command Explained

The locate command is often the simplest and quickest way to find the locations of files and directories on Linux and other Unix-like operating systems.

The basic syntax for locate is:

locate [options] name(s)

When used without any options, locate displays every absolute pathname for which the user has access permission that contains any of the names of files and/or directories that are provided to it as arguments (i.e., input data).

The absolute pathname, also referred to as the absolute path or the full path, is the hierarchy of directories from the root directory to the designated file or directory. The root directory is the directory at the very top of the filesystem (i.e., hierarchy of files) that contains all other directories and files on the system and which is designated by a forward slash ( / ). It is important that the absolute pathname is returned both because it tells the exact locations on the system and because it makes it possible to indicate the locations of files or directories that have the same name but different absolute paths.

Thus, for example, the following would list the absolute paths of all files named file1 and all directories named dir1 for which the user had access permission:

locate file1 dir1

It would also list any other absolute pathnames that contained these strings (i.e., sequences of characters), for example /home/john/file123 or /usr/local/mydir1/index.html.

The specificity of locate can be increased by using it together with wildcards or other regular expressions. Wildcards are characters that can be used to substitute for any other character or characters. For example, the star character ( * ) is a wildcard that can represent any single character or any string containing any number of characters. Regular expressions are a string that describes or matches a set of strings, according to certain syntax rules. For example, the following command uses the star wildcard to display all files on the system that have the .png filename extension:

locate “*.png”

The -q option is used to suppress error messages, such as those that might be returned in the event that the user does not have permission to access designated files or directories. Thus, the following would suppress any error messages in the above example:

locate “*.png” -q

It is often the case that a large number of results will be returned for any query. The -n option followed by an integer limits the results to a specific number. For example, the following command would display only 15 results in a search for files that have an .html extension:

locate -n 15 “*.html”

An alternative is to use a pipe (represented by the vertical bar character) to redirect the output of locate from the display screen to a pager such as more or less, which presents only one screenful of output at a time, for example,

locate “*.html” | less

The -i option performs a case-insensitive search. That is, it will return any results that match the arguments regardless of whether individual letters are lower case or upper case. For example, the following would return all files with the extension .html, .HTML, or some combination thereof:

locate -i “*.HtmL”

On some systems, such as Red Hat, the program slocate is installed by default instead of locate, and entering the locate command activates a script (i.e., a short program) that causes slocate to be launched. slocate provides a secure way to index and quickly search for files on a system by storing file permissions and ownership data so that users will not see files for which they do not have access.

The -V option can be used to show which version of locate is used, including whether it is locate or slocate. Another way to determine whether slocate is being used is to see if an absolute pathname such as /usr/bin/slocate is returned when the following command is issued:

locate locate

locate and slocate actually search a built-in database, named locate.db or slocate.db, respectively, rather than the entire hard disk drive itself, in order to provide a much shorter searching time. This database is automatically updated on a regular basis by cron, a small program that runs in the background, performing various tasks at regularly scheduled intervals. The updating is performed each night if the computer is on continuously.

Because the database is not updated immediately, recently created files and directories might not show up when searching for them with locate or slocate. Fortunately, however, it is a simple matter to update the database manually, although it might take a few minutes. Manual updating can be accomplished by logging in as the root user (i.e., administrative user), such as by using the su (i.e., substitute user) command, and then issuing the following command:

updatedb

The same thing can be accomplished by the root user by using locate with its -u (i.e., update) option, i.e.,

locate -u

For the curious, the database is located at /var/lib/slocate/slocate.db on some systems, such as Red Hat. Its exact location on any particular system can be found by the root user (because ordinary users will not have access permission on most systems) with the locate command as follows:

locate locate.db

The database is a binary file (i.e., a non-text file). However, for the really curious user who has root permission, the human-readable portion of its contents can be viewed by first using the strings command to extract all the plain text and by then piping the output to less for displaying one screenful at a time as follows:

strings /var/lib/slocate/slocate.db | less

If it is desired to perform a more sophisticated search, including searching by attributes other than name (e.g., by size, creation date or location), the find command should be used.

Linux ‘Du’ Command Explained

The du Command – shows the sizes of directories and files.

The du (i.e., disk usage) command reports the sizes of directory trees inclusive of all of their contents and the sizes of individual files. This makes it useful for tracking down space hogs, i.e., directories and files that consume large or excessive amounts of space on a hard disk drive (HDD) or other storage media.

A directory tree is a hierarchy of directories that consists of a single directory, called the parent directory or top level directory, and all levels of its subdirectories (i.e., directories within a directory). Any directory can be regarded as being the start of its own directory tree, at least if it contains subdirectories. Thus, a typical computer contains a large number of directory trees.

du is commonly employed by system administrators as a supplement to automated monitoring and notification programs that help prevent key directories and partitions (i.e., logically independent sections of a HDD) from becoming full. Full, or even nearly full, directories and partitions can cause a system to slow down, prevent users from logging in and even result in a system crash. Although visually identifying heavy consumers of disk space can be practical if there are relatively few users on a system, it is clearly not efficient for large systems with hundreds or thousands of users.

A minor limitation of du is the fact that the sizes of directories and files it reports are approximations, not exact numbers, and there is frequently a small discrepancy between these sizes and the sizes reported by other commands. However, this rarely detracts from its usefulness.

Also, du can only be used to estimate space consumption for directories and files for which the user has reading permission. Thus, an ordinary user would generally not be able to use du to determine space consumption for files or directories belonging to other users, including those belonging to the root account (i.e., the system administrator). However, as du is used mainly by system administrators, this is usually not a problem.

Syntax

The basic syntax for du is:

du [options] [directories and/or files]

The items in the square brackets are optional. When used with no options or arguments (i.e., names of directories or files), du lists the names and space consumption of each of the directories (including all levels of subdirectories) in the directory tree that begins with the current directory (i.e., the directory in which the user is currently working). The space consumption of any directory consists of the space occupied by all of the files in it and all of its subdirectories at all levels inclusive of all of the files in them. A final line at the end of the report gives the total space consumption for the directory tree.

du can provide information about any directory trees or files on the system whose names are given as arguments. For example, the following will report the names and sizes for each directory in the directory tree that begins with a directory named directory2 that resides in a directory named directory1, which, in turn, is located in the current directory:

du directory1/directory2

Likewise, the following will report the sizes of the two files named file1 and file2 that are located in the /sbin directory (which contains executable programs):

du /sbin/file1 /sbin/file2

du can accept any number of arguments, and they can be any combination of files and directories. When there are multiple arguments, no grand total is provided by default, although a total is still provided for each argument.

Options

As is the case with most commands on Linux and other Unix-like operating systems, du has a number of options, a few of which are commonly used. The options can vary somewhat according to the particular operating system and the version of du.

One of the most useful options is -h (i.e., human readable), which can make the output easier to read by displaying it in kilobytes (K), megabytes (M) and gigabytes (G) rather than just in the default kilobytes. Thus, the following command can be used to show the sizes of all the subdirectories in the current directory as well as the total size of the current directory, all formatted with the appropriate K, M or G:

du -h

The -s (for suppress or summarize) option tells du to report only the total disk space occupied by a directory tree and to suppress individual reports for its subdirectories. Thus, for example, the following would provide the total disk space occupied by the current directory in an easy-to-read format:

du -sh

The output is the same as the last line of a report issued by du with only the -h option.

The -a (i.e., all) option tells du to report not just the total disk usage for each directory at every level in a directory tree but also to report the space consumption for each individual file anywhere within the tree. Thus, for example, the following would list the name and size of every directory and file in the /etc directory (which contains system configuration files) for which the user has reading permission:

du -a /etc

A somewhat similar report is provided by using the star ( * ) wildcard, which will match any character or characters. For example, the following command would list the sizes of all directories that are in the tree that begins with the current directory:

du *

However, the only files listed are those in the the parent directory, not those in its subdirectories. Also, no total for the directory tree as a whole is provided.

The use of the -s option and the star wildcard together would cause du to report the names and sizes of only the files and directories contained directly in the top level directory itself (and to not list the names of any of its subdirectories and the files in them). The size of each listed directory is, of course, inclusive of all of its files and subdirectories (including all of the files in them). For example, such a report about the directory tree beginning with the current directory would be provided by the following:

du -hs *

The wildcard can also be used to filter the output to list only those items whose names begin with, contain or end with certain characters or sequences of characters. For example, the following would report the names and sizes of all of the directories and files in the current directory whose names begin with the letter s as well as the names and sizes of all levels of subdirectories of those directories regardless of what their names begin with:

du -h s*

The -c option can be added to provide a grand total for all of the files and directories that are listed. In the case of the above example, this would be

du -hc s*

As another example of the use of the wildcard, the following command would report the name and size of each gif (one of the two most popular image formats) file in the current directory as well as a total for all of the gifs:

du -hc *.gif

Another useful option is –max-depth=, which instructs du to list its subdirectories and their sizes to any desired level of depth (i.e., to any level of subdirectories) in a directory tree. For example, the following would cause du to list only the first tier (i.e., layer) of directories in the current directory and their sizes (inclusive of all of their contents, including those of their subdirectories):

du –max-depth=1

The total space consumption for the current directory tree will also be reported, and it will, of course, be the same regardless of the depth of the files listed.

Setting –max-depth= to zero tells du to not list any of the subdirectories within the selected directory, i.e., to list only report the size of the selected directory itself. The result is the same as using the -s option.

Using du With Filters

As is the case with other commands on Unix-like operating systems, du can be linked with pipes to filters to create powerful pipelines of commands. A filter is a (usually) small and specialized program that transforms data in some meaningful way.

For example, to arrange the output items according to size, du can be piped to the sort command, whose -n option tells it to list the output in numeric order with the smallest files first, as follows:

du | sort -n

As du will often generate more output than can fit on the monitor screen at one time, the output will fly by at high speed and be virtually unreadable. Fortunately, it is easy to display the output one screenful at a time by piping it to the less filter, for example,

du -h | less

The output of less can be advanced one screenful at a time by pressing the space bar, and it can be moved backward one screenful at a time by pressing the b key.

The output of du can likewise be piped to less after it has been passed through one or more other filters, for example,

du -h | sort -n | less

The grep filter can be used to search through du’s output for any desired string (i.e., sequence of characters). Thus, for example, the following will provide a list of the names and sizes of directories and files in the current directory that contain the word linux:

du -ah | grep linux

One way in which du can be used to produce a list of (mostly) directories and files in a directory tree that are consuming large amounts of disk space is to use grep to search for all the lines that contain the upper case letter M (i.e., for megabytes) or G (for gigabytes), such as

du -ah | grep M

The only problem with this approach is that it will also select directories and files that contain an upper case M or G in their names even if the file size is not measured in megabytes or gigabytes. (However, this problem could be overcome through the use of regular expressions, an advanced pattern matching technique).

Alternatives to du

There are several other ways of monitoring disk space consumption and reporting file sizes. Although very useful tools, they are generally not good substitutes for du.

Among them is the df command, which is likewise used by system administrators to monitor disk usage. However, unlike du, it can only show the space consumption on entire partitions, and it lacks du’s fine-grained ability to track the space usage of individual directories and files.

du is not designed to show the space consumption of partitions. The closest that it can come is to show the sizes of the first tier of directories in the root directory (i.e., the directory which contains all other directories and which is represented by a forward slash), several of which may be on their own partitions (depending on how the system has been set up). This is accomplished by becoming the root user and issuing the following command:

du -h –max-depth=1 /

The ls (i.e., list) command can provide the sizes of individual files by using its -s option, and its -h option (which is similar to du’s -h option) can be added to make the output easier to read. For example, the following would list the names and sizes of the files in the current directory:

ls -sh

Although the names of the first tier of directories within the current directory are also listed, the size data accompanying them does not represent their actual disk space consumption (i.e., inclusive of their contents). Nor does ls report the contents of any lower tiers of directories, unless such directories are specifically listed as arguments.

A convenient alternative for finding the sizes of files and directory trees when using a GUI (graphical user interface) is to click with the right mouse button on the icon (i.e., a small picture or symbol) for that item and then select Properties from the menu that appears. Although this is frequently sufficient, it does not provide the detailed control and reporting that du provides.

Joker Lets You Instantly Stream Perfectly Legal And Legitimate Torrent Files

joker

Let’s say there’s a torrent online you would like to view. After all, torrents themselves are perfectly legal. Instead of downloading the torrent, paste the link to the torrent in Joker.org and watch the content instantly. Watch out, Popcorn Time. The Joker is here.

Using Joker.org to watch a torrent is stupid easy. Grab a Torrent magnet link — the more seeds the better — and paste it into the text input box on the home page of Joker.org. From there, the service seems to cache the content, and depending on the amount of seeds, it starts playing after an ad.

Streaming is not a newly discovered torrent function. Programs and services have offered the functionality for years, yet Joker.org’s implementation is clean and elegant. And that’s why it probably won’t last long.

Legitimate torrents or not, Joker will clearly be used for pirated content and the site is trying to make money. Ads play prior to the video plays back. With ads, likely come a paper trail and the MPAA has successfully taken down sites with much less information to go on.

TorrentFreak points out that the site appears to cache the torrents, too, which requires servers and bandwidth. This is most likely to improve playback. However, the cached content could be grounds for a takedown notice since it will no doubt include pirated content.

Enjoy Joker while it lasts and use it at your own risk. It’s a magical experience — that is, when used for perfectly legal and legitimate torrent files.

What is Java Atmosphere Framework ?

Atmosphere is a Java/Javascript Framework. It allows the creation of portable asynchronous web applications using Groovy, Scala & Java.

Atmosphere supports all modern web browsers. It also supports server components supporting all major Java based web servers.

It supports WebSockets, Server Side Events (SSE), Long Polling, HTTP Streaming, JSONP etc.

The aim of the framework is to allow a developer to write an application and let the framework discover, the best communication channel between the client and server, transparently.

For example, a developer can write an application that will use the Web Socket protocol when used with a browser on server that supports the protocol and transparently fail, changing to HTTP in ease where Web Socket isn’t supported

11 Important Maven Commands

1.Creating a maven standalone project

mvn archetype:generate -DgroupId=org.cloudhadoop -DartifactId=myproject

This is the starting step for any java project to create. This command runs at command prompt and create myproject with project name i.e. artifact id. This project is located in group “org.cloudhadoop” using groupid,.
After running this command for the first time, this tries to download all the required artifacts downloaded from remote repositories ( from maven .. etc) and copy to your localrepository and after that it create a project. This project contains the src/main/java and src/test/java folders which contain the hellowold java program in main folder, and test class for hell0world program in test folder.

2.Creating a web standalone project

mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes
-DarchetypeArtifactId=maven-archetype-webapp -DgroupId=com.cloudhadoop
-DartifactId=mywebapp

Most of the times, we usually create a web based projects in eclipse. With this command also, we can create web project like spring, struts which contains, WEB-INF, lib, classes folders and web.xml. This command runs at command prompt and create mywebapp with project name i.e. artifact id. This project is located in group “org.cloudhadoop” using groupid,.
After running this command for the first time, this also tries to download all the required artifacts downloaded from remote repositories ( from maven .. etc) and copy to your localrepository and after that it create a project.
The directory structure is different from the #1 command and creates as per maven directory structure for web applications.

3. Cleaning project

mvn clean

As you know target folder contains all your compiled classes, as well as jar,war files when you run project with maven install.
Clean is maven predefined goal, this command delete all the contents in the target folder.

4. compile maven project

mvn compile

compile is maven predefined goal ,this command complie all your java classes which includes src files as well as test files in your project.

5.Build web apps

mvn package

maven package goal is used to build maven applications.
As you know any java project can be packed as jar or war.
Package is maven predefined goal. By giving this command, first compile all the java files(using compile goal) and run all your test classes and copy all this files to target folder and create a jar, war file. The final out put for this command is jar/war of your project located in target folder.

6.Deploy project

mvn install or
mvn deploy

When we run this command under your project, it will do all the tasks in “mvn package” and create the required jar/war file in target folder.
Maven install goal is used to deploy the project(jar/war) to the local repository. and local repository location is /.m2/repositories/groupid/.
Maven deploy goal is used to deploy the project to the remote repository like nexus. so that other developers can use this artifact in their module. remote repository location is specified in pom.xml.

7. Run unit and integration tests

mvn test

Test goal is used to run only the test classes in your project. The test files are located under src/test/java and copy the result to your target/test-classes, target/reports if any.

8. Ignore test execution

mvn package –DskipTests or
mvn package -Dmaven.test.skip

In 4#, with maven package command run, tests are also executed. If you want to skip the unit tests, The we can use this command. You can use this option with install goal also.

9.Generate java documentation for project

maven javadoc:javadoc

This will generate java documentation for your project. And the generated java doc report can be found in target folder
This will includes API documentation for your java classes in your project.
10. Debug maven

mvn -X

This command is used to start the maven goals in debug mode and gives logging information. This command gives more information like what artifact is failing for what reason .
This command can be used when you are not getting any clue for your maven project execution failure.

11.Generate site

mvn site

Predefined goal in maven is used to generate site documentation in formatted style.
