Aperion Audio sent over a press release announcing its new. The gadget connects to the local network via a wireless or Ethernet connection, and pulls music from a desktop or laptop running Windows 7. Unfortunately, it doesn’t come cheap, costing a meaty $499 which includes the Aris Wireless Card for Windows.

‘The ARIS Wireless Speaker combines our experience in making wireless speaker systems with the media capabilities of the Windows operating system,’ says Mike Hopkins, Product Development Manager at Aperion Audio. ‘The result is effortless listening from any room. Plus, with the new ARIS app, smartphone users can choose music from any device on their network and instantly send it to any connected Aris speaker.’

Aperion says the speaker can quickly connect to a home network with the push of a button using Wi-Fi Protected Setup. The ‘Play To’ feature in Windows 7 allows users to send music from any device on the network to an Aris speaker located where they want to listen.

According to Aperion, key features include a single-piece brushed aluminum enclosure (6.5 inches high by 14.75 inches wide), an adjustable and removable steel base, and six internal speakers consisting of four powered drivers and two passive radiators. Overall it has a total power of 100w RMS.

‘Most people today store their music on a variety of digital devices, including desktops, laptops, notebook PCs, network storage drives, tablets and smartphones. These devices are usually on the home network, but users can listen to music only on a device that is physically plugged into a powered speaker or stereo system. The ARIS wireless speaker eliminates the need to move music files between devices or plug and unplug cables to hear specific tracks.’

Other features include three sound modes (natural, bass boost and enhanced stereo), and DLNA support. Windows 8 support is still pending, but the company mentioned that it should work with Windows 8 Consumer Preview.

Pre-orders will be accepted starting May 8, 2012, and the system is expected to ship mid-June 2012. The one-year limited warranty covers all defects in material and workmanship, Aperion said.

The manufacturer will be shipping with a technology called ‘Duralock’, which guarantees power storage for at least 10 years.

To achieve the increase in storage duration, Duracell said that it uses 24 karat gold as ‘fuel’ for creating chemical power, protects the anode and cathode with a unique separator that limits power transfer when not in use, and applies ‘triple corrosion protection’ that surrounds the contents in an acid resistant. There is also a battery anti-corrosive exterior.

‘We know that consumers typically don’t spend a large amount of time thinking about batteries,” said Volker Kuhn, general manager for Duracell North America, in a prepared statement. “But with the demand for more battery power on the rise due to the large amount of battery-operated devices on the market, it’s important that Duracell is recognized as a power solution they can trust.’ Duracell said that the average household has about 20 devices that rely on batteries.

The company said that it will launch the new technology with the support of its ‘largest marketing campaign in [the company’s] history’. The new batteries are scheduled to be available in U.S. retail by late summer.

If there’s one thing you could say about John Carmack, it’s that he’s an interesting read to say the least. On October 30, id Software finally released the iPhone version of Doom Classic. For $6.99, gamers get 36 levels of classic Hell goodness from all four original episodes: Knee-Deep in the Dead, Shores of Hell, Inferno, and Thy Flesh Consumed. The game even provides deathmatch and cooperative play for up to four players via ‘wireless Internet.’

Once the game finally swam past the infamous Apple mad scientists stationed in the App Store, Carmackof the iPhone remake, talking about putting the project aside to work on Doom 4(!) and Rage, or how id software decided to put the game aside so it didn’t clash with Doom Resurrection. He even goes into the whole networking issue, revealing how 3G was disappointing and overall caused ping times of 360 ms despite its ‘speed.’

But somewhere in that plethora of gaming goodness, Carmack revealed that the company is indeed working on Quake Classic for the iPhone. ‘We have two people at Id that are going to be dedicated to iPhone work,’ he said. ‘I doubt I will be able to personally open Xcode again for a few months, but I do plan on trying to work out a good touch interface for Quake Classic and the later 6DOF games.’

Carmack also said that there may be a free tech demo using the company’s idTech 5 megatexture content creation pipeline, and also mentions the Rage themed game in his update as well.  ‘I’m not sure exactly what game I would like to do with it, so it might be a 500 MB free gee-whiz app,’ he said, referring to the idTech 5 demo. ‘I want to work on a Rage themed game to coincide with Rage’s release, but we don’t have a firm direction or team chosen for it.  I was very excited about doing a really-designed-for-the-iPhone first person shooter, but at this point I am positive that I don’t have the time available for it.’

Quake… my favorite game of all time! -kp

To watch any video content — whether on cable TV, DVD, Blu-ray, Netflix or YouTube — your device needs a way to understand the data and convert it into an image. That’s the job of video codec software. With 4K content,which has four times the resolution of HD, there is a need for new codecs that can deliver the quality of Ultra HD content, yet compress it down so all that data can fit within the bandwidth of people’s home Internet connection and perhaps onto discs someday. With the VP9 codec, Google is working to fill that void.

What is VP9?

VP9 is a new video codec that will compress video files to half the size that the current encoding technology, called MPEG-4 or H.264, can achieve. More important, it will be used to compress video files and streams atresolution, which is four times higher than HDTV resolution. VP9 is part of WebM, an open-source project sponsored by Google for creating technology for use with media on the Internet. Google has announced plans to use VP9 for 4K YouTube videos. But VP9 rivals another technology, called, that also seeks to be the standard for 4K TV. 

What is a codec?

A codec (an abbreviation of the term ‘coder-decoder’) is software that uses an algorithm to systematically compress raw video data into a compact form fit for efficiently broadcasting, transmitting over an Internet stream or storing on a DVD or Blu-ray disc, for example. Without a codec, there simply wouldn’t be enough bandwidth or storage space for HDTV to be possible.

At the receiving end, the same codec in your TV, computer or disc player uncompresses the data to display the video on your screen. Codecs also remove some detail from video to reduce its size, and a high level of compressions can noticeably degrade image quality. Most pay-TV services use aggressive compression to get all those channels into your cable or satellite receiver, which is one reason the video from your cable box does not look as good as that from a Blu-ray. A good codec will compress video down while causing few defects due to overcompression.

High-definition video can take a lot of data. A full-HD image has about 2 million pixels and potentially millions of colors making up an individual frame, with hundreds of thousands of frames making up a movie.

Why use VP9 for 4K video?

The current MPEG-4/H.264 codec makes it possible to compress the huge amount of information in a film so that it can stream over online video services such as Netflix or YouTube. Those high-definition images are in either 720p resolution (1280 x 720 pixels, or 0.92 million pixels) or 1080p resolution (1920 x 1080 pixels, or about 2 million pixels). The images from a video in the 4K format, also known as Ultra HD, have about 8.3 million pixels (3840 x 2160 resolution). Such a huge jump in detail requires a better way to compress the data in order to transmit or store it. VP9 is twice as efficient as H.264. The result is that current HD content will need only half the data to be streamed, and streaming 4K content will be viable. 

What content will use VP9?

Google is ostensibly responsible for the creation of the VP9 codec and has already announced it will be used for 4K content on YouTube. It will also likely be used by the Google Play streaming video service. Each individual service will have to decide whether to start sending data using VP9 instead of the current H.264 codec. And even once content is being made using VP9, there will have to be compatible hardware to run it, from TVs, to set-top boxes to mobile devices. Google has already announced some partners, including chip and component makers ARM, Broadcom, Intel, Marvell, MediaTek, Nvidia, Qualcomm, RealTek and Sigma, as well as TV makers LG, Panasonic, Philips, Samsung, Sharp, Sony and Toshiba. 

The other wrinkle is that there is another 4K codec called, developed by the international organizations that created H.264 (as well as its predecessor, MPEG-2). Some video services, such as Netflix, and hardware companies may support only HEVC. Others may support only VP9. Still others may support both 4K codecs, as Samsung and Sony are doing with upcoming 4K televisions.

MORE:

How is VP9 different from HEVC?

There are technical similarities between VP9 and HEVC, and the overall goal of the two codecs is the same: compress video to use half the data currently required to stream HD video and provide enough compression for 4K video to become viable within the limits of high-speed Internet in people’s homes. The biggest difference is that VP9 is an open-source project that can be used by anyone royalty-free, whereas HEVC will require a license to be used. Whether there is an actual difference in compression effectiveness and picture quality remains to be seen when 4K content created with both codecs is widely available.

Can I watch VP9 content now?

Not really. Even though Google has pushed support of VP9 to its Chrome browser, only a few YouTube videos are using it and likely only as a test. (You can right-click a video in the HTML-5 version of the YouTube player and click on the ‘stats for nerds’ choice to see what codec is being used.) Even when YouTube or another service begins streaming more content with VP9, you will only be able to watch it with a compatible television, computer or mobile hardware.

How did VP9 come about?

A company called On2 Technologies created the TrueMotion and TrueMotion2 codecs. For the next version in 2000, the company’s CEO, Daniel B. Miller, renamed it Video Processing 3, or VP3. VP3 was made open-source in September 2001, and is now called Theora. Over the years, On2 Technologies created improved versions such as VP4, VP5, etc. The company was acquired by Google in 2010, making future codecs open-source like Theora. VP9 is just the latest of Google’s open-source projects meant to improve the delivery of content on the Internet.

An. As it stands now, the current PlayStation 3 is an excellent entertainment hub given that customers aren’t forced to pay an added ‘network fee’ (like Xbox Live) to access subscriptions such as Netflix and Hulu Plus. The drawback is that the PlayStation 3’s non-gaming offering isn’t quite as robust as the Xbox 360, but perhaps that will change with the new console.

According to the unnamed official, the main selling point of the PlayStation 4 will be new styles of play, not the updated hardware set which supposedly includes a rumored eight-core AMD64 CPU. If anything, Sony will promote the new hardware as a means of breaking away from the traditional console mindset by allowing mobile devices to connect and share media and other goods. It will be the ‘nerve center’ of your house, the official claimed.

. Unlike OnLive which serves up a streaming subscription, rentals and full-blown game purchases directly to members, Gaikai serves as the middleman between the seller and the buyer — it’s a platform only. There’s a good chance PlayStation 4 owners will be able to purchase games from Sony that can be stored and streamed from the cloud.

That said, it’s quite possible PC-based games provided by SOE could be offered on the console as well like EverQuest 2 or the just-launched Wizardry Online (aka speculation). The paper said that the console will be ‘fully networked’ and ‘be furnished with the ability to exchange opinions amongst one’s friends while playing games.’ A fully-networked console could mean it will be dual-band so that it can access the less-congested 5 GHz band on compatible networks, thus improving streaming performance.

 

 

Sony’s PSVita isn’t expected to hit shelves for another couple of months, but that doesn’t mean the tech industry has lost interest in the device. In fact, new information regarding the console is making the headlines every week and this latest tidbit might be one of the most interesting things we’ve heard to date.

Eurogamer reports that Sony Europe R&D manager Phil Rogers recently revealed the new portable can also be used as a controller for the PS3. Rogers revealed the feature while speaking to Develop 2011 attendees:

‘PS3 can send data down to Vita and Vita can display it,’ Rogers is quoted as saying. ‘You could use the unique features [of Vita] – gyroscope, touch front and back – as a control device for a PS3 game.

‘You can run software on both devices and use the network to sync the game states. And that’s pretty good, because you then have the processing power of PS3 doing that work, Vita [doing] fancy graphics – however you want to do it. You’re not sacrificing the PS3’s CPU to be able to have a rich experience on Vita.’

The news of Wii U-like compatibility with the PS3 makes the Vita even more interesting. Rogers said that Vita will also support cross-platform play (Wipeout 2048 being one of the titles that utilizes this feature) as well as other cross-platform features, like scoreboards.

Do all these new features have you itching to get PSVita once they do arrive in stores? Let us know in the comments below!

Come midnight, Kinect will be available in retail outlets across the country. Provided the system doesn’t sell out, you should be able to stroll down to your local electronics store and pick up Kinect whenever you have the time. Still, there’s something to be said for being among the first to get a newly released product and Microsoft is providing a little extra incentive for those close to NYC to get off their butts and head down to the official launch at Toys R Us in Times Square.

Toys R Us is opening its doors at midnight so it can sell Kinect as soon as calendars tick over to November 4, and Microsoft is giving the first 3,000 people to purchase Kinect a free copy of Kinect Sports, a copy of Kinect Joy Ride and a one year Xbox Live Gold subscription. That’s $150 of swag right there, but that’s not all; Microsoft is also giving the first 400 people (over the age of 18) an invitation to the launch after-party where it’s promising ‘surprise appearances.’

So who’s in line already? A lot of people, that’s who. This is Peter (right) and K (left). Peter has been sitting outside the store since 7pm on Monday, while K arrived Tuesday morning at 9am. Peter says he wants to be among the first to get Kinect, while K said he’s there to be in that first 400 going to the after party. When asked if that was the only reason he was there so far in advance, he responded, ‘That’s it. I wanna go to the after-party.’ Peter said he was buying the peripheral for himself, while K said his wife would probably play it a lot.

Given how early these guys showed up (and their lack of gear), I’m assuming they’re from New York. However, one family made a trip from eastern Pennsylvania to make sure they get Kinect first and they were well prepared for the long wait with plenty of blankets and snacks to keep them going. Arriving at 7 a.m. this morning, they they seemed extremely excited about the prospect of Kinect and admitted they’d be taking it out of the box ‘as soon as they got home.’ That said, they also admitted that they arrived so early because they wanted to secure after-party tickets.

‘We got the train in the middle of the night to be here this morning at 7am,’ said mom, cheerfully. ‘We were going to come in last night but we checked the Facebook page and they said there were only about 20 people so far so we waited until today.

‘We were about 40th in line when we arrived but people have been showing up and joining their friends up ahead so I think we’re probably about 60th now. We’ll still be in the top 400, though, I think.’

We counted about 80 people in the queue, but there were also plenty of empty chairs where people had left their posts, we assume in search of refreshments or a bathroom.

Things don’t officially kick off until 6 p.m. but Microsoft reps were on hand all day to give passersby a chance to try out Kinect and folks in line were encouraging people to try out the system and then join the queue. We’ll head back to Times Square later on this evening to see what’s going down so be sure to check back for more!

Learn about Apache Maven- A Build Automation Tool

What’s up, everyone! Today we will be going to talk about Maven.

We will start with the quick intro and then list down the advantages of using it. After all this, we will see its installation process and then a few technical terms which are essential for a beginner. So, let’s get started!

What is Maven?

Apache Maven is a project management software, and we can say it is a comprehension tool. It is based on the concept of the project object model (POM) [will be discussed later in the articles], Maven can manage a project’s build, reporting, and documentation from a central piece of information.

Apache Maven is a build tool, and it does the task just like Ant, which is again an extraordinary build Tool. This is a software project management tool that gives a new concept of the project object model (POM). Maven allows the developer to automate the handling of the creation of the original folder format, performing the assortment and testing and the packaging and deployment of the final output. It cuts down the considerable number of steps in the base process, and it makes it jus one-step process to do a build.

Why is Maven Used?

To sum up, Maven simplifies and standardizes the project build process. It handles team collaboration, compilation, distribution, documentation, and separate tasks seamlessly. Maven increases reusability, and it also takes care of most of the build-related tasks. It works in helps many steps such as adding jars to the project library, building reports, and executing Junits test cases, creating Jar, War, Ear files for the project, and even many more things.

A highly significant aspect of Maven is the purpose of repositories to manage jar files.

The Maven can further be used in building & managing the projects written using languages like C#, ruby, and other.

Let’s take a look at the following Maven advantages.

Convention over configuration

  • Its configuration is very minimal.
  • It has managing dependencies.

Multiple/Repeated builds can be achieved

  • Automation makes it easy.

Plugin management, testing, and development

  • It has the ability to run JUnit and other integration tests.
  • It makes the development process clear.

Provisions to check the status of every build

  • It avoids inconsistent setups.
  • Standard and uniformed infrastructure among projects.

Setting up Maven Environment

The installation of Maven includes the following steps:

  • Check whether the system has Java installed or not. if not then install java
  • Check whether java Environment variable is set or not. If not, then set java environmental variable.
  • Download
  • Unzip the maven download at one place in the system.
  • Now, add the bin directory of the created directory apache-maven-3.6.2 to the PATH environment variable and system variable.
  • Open cmd and run mvn -v command to confirm the installation.

That’s all

To get the detailed steps of the installation, follow the below YouTube guide to setup Maven Environment as we don’t want to make this article simple reading stuff and boring too.

As this is a beginner guide so it must include technical terms related to MAVEN. So here are few, which are very important:

Maven Local Repository

Maven Local Repository is the set where Maven stores all the project jars files or libraries or dependencies. By default, the folder name set to ‘.m2 ‘, and by default, the location is ‘Libraries\Documents\.m2 ‘.

Maven Central Repository

Maven central repository is the default location for Maven to download all the project dependency libraries for the use. For any library involved in the project, Maven first looks into the .m2 folder of Local Repository, and if it does not find the needed library, then it seeks in Central Repository and loads the library into the local repository.

Maven POM

POM is a Project Object Model XML file that has information about the project and configuration details needed by Maven to develop the project. It contains default values for most projects. Some of the structures that can be defined in the POM are the project dependencies, plugins that can be executed, and of course, the build profiles.

Elements used in Creating pom.xml file

  • project- Project is the root element of the pom.xml file.
  • modelVersion- It means the version of the POM model you are working with.
  • groupId- It implies the id for the project group. It is unique, and Most often, you will apply a group ID that is related to the root Java package name.
  • artifactId- This is used to provide the name of the project you are building.
  • Version- This element consists of the version number of the project. If your project has been released in various versions, then it is convenient to present the version of your project.

Dependency Keyword

Dependencies are the libraries, which are needed by the project. Like Log4j jars, Apache Poi jars, Selenium Jars are few libraries that are required for the project. Dependencies, in the Maven pom.xml, are mentioned like this:

<dependencies> <dependency> <groupId>com.companyname.groupname</groupId> <artifactId>App-Core-lib</artifactId> <version>1.0</version> </dependency></dependencies>

Surefire Plugin

The Surefire Plugin is needed during the test phase of the build lifecycle to implement the unit tests of an application. It makes reports in 2 different file formats like plain text file, XML files, and in HTML files also. Even if you are using Junits framework or TestNG for reporting, this plugin is a must for use, as it helps Maven to find tests.

Practical Application Of Maven

When working on a specific java project, and that project has a lot of dependencies, builds, requirement, then working with all those things manually is hugely complex and laborious. Thus using some tools that can work out these works is truly helpful.

And Maven is such a build management tool which can perform all the things like adding dependencies, using the classpath to project, making war and jar file automatically and many new things.

Conclusion

This tool is beneficial when it comes to building projects. I wish you success in your JAVA project. If you are looking for a video tutorial, then you may check out the.

Amazon.com today introduced the company’s second generation electronic reader, the Kindle 2. The follow up from the company’s successful Kindle ebook reader offers customers a slim new design with longer battery life, faster page turns, over seven times more storage, sharper images, and a new read-to-me feature.

Rumors that Amazon was about to unveil the next Kindle did the rounds at the very end of January. The company announced it would be holding a press conference at the Morgan Library in New York City on February 9; and while there was no mention as to whether or not we’d see the revamped Kindle, the notice on the Kindle site that says orders placed for the device will ship in 4-6 weeks didn’t go unnoticed, especially when you consider the Kindle drought a result of the device’s Oprah debut. 

Despite the fact that the newest Kindle sports a 600 x 800 6-inch electronic paper display that looks and reads like real paper, most will be a little disappointed to find out there’s still no touch screen on Amazon’s reader. With 2 GB of memory, Kindle 2 can hold more than 1,500 books, compared with 200 with the original Kindle. More memory is always welcome and Amazon has kept the price for this version the same as the old: $349

A few hours before the event, word went around that Stephen King would be launching the Kindle and true enough, the novelist was there. King said he would be writing a story for the Kindle and he read an excerpt of ‘Ur’ to the crowd, which is actually about a Kindle and sounds completely dire, but there you go.

‘Author Stephen King announced today that he is releasing a novella, “Ur,” which will only be available on Kindle. At the center of Ur is lovelorn college English instructor Wesley Smith, who can’t seem to get his ex-girlfriend’s parting shot out of his head: ‘Why can’t you just read off the computer like the rest of us?’ Egged on by her question and piqued by a student’s suggestion, Wesley places an order for a Kindle. Smith’s Kindle arrives in a box stamped with the smile logo and unlocks a literary world that even the most avid of book lovers could never imagine. But once the door is open, there are those things that one hopes we’ll never read or live through.

Customers can preorder now and units are set to ship February 24.

If you want to get serious about, you’re going to need a high-quality microphone.

But many of the best mics out there are pretty bulky, which is a problem for streamers who travel often — or simply don’t want a big microphone taking up a chunk of their camera feed. That’s where Razer’s new $99 Seiren X comes in.

The Seiren X uses what Razer calls a ‘Super Cardoid’ pickup pattern, which is designed to record your voice with precision while filtering out unwanted noise. However, when comparing voice recordings between the Seiren X and the Yeti’s Cardoid mode, I noticed that Razer’s microphone let in a lot more background noise. The Seiren X did pick my voice up with decent clarity, but it might not be the best mic out there for recording in noisy environments.

While the Seiren doesn’t have all the features or overall quality of the $129 Yeti, it’s also $30 cheaper. And its portability really is killer, especially for on-the-go streamers who want something a little more robust than, say, the $36 Samson Go Mic.

The Seiren X is launching alongside, which is the first USB webcam with a built-in ring light for illuminating your face (my colleague Andrew Freedman loved it; check out his review here). Between the Seiren and the Kiyo, Razer seems fully committed to solving some very specific problems for aspiring Twitch and YouTube stars, and we’re eager to see what the gaming giant cooks up for broadcasters next.
