Linux Mint 12 Released Today 8

Linux Mint 12
An anonymous reader writes "Linux Mint 12 was released today. It includes the new 'MGSE' (Mint Gnome Shell Extensions), a desktop layer on top of Gnome 3 that makes it possible for you to use Gnome 3 in a traditional way. MGSE's Gnome-2-Like experience includes features such as the bottom panel, the application menu, the window list, a task-centric desktop and visible system tray icons. MGSE is a 180-degree turn from the desktop experience the Gnome Team is developing with Gnome-Shell. At the heart of the Gnome-Shell is a feature called 'the Overview': 'The Shell is designed in order to minimize distraction and interruption and to enable users to focus on the task at hand. A persistent window list or dock would interfere with this goal, serving as a constant temptation to switch focus. The separation of window switching functionality into the overview means that an effective solution to switching is provided when it is desired by the user, but that it is hidden from view when it is not necessary.' The popularity of Mint 12 with MGSE may be an excellent barometer as to whether users prefer a task-centric or application-centric desktop."

Amazon Kindle Fire vs. Touch vs. Keyboard: Which E-Reader Is Right For You?

The Amazon Kindle is one of the hottest gifts this holiday season, but if you're looking to buy one, it might be daunting to decide which is right for you.

You know the basics of the Kindle e-readers: access to over 800,000 books, the lending library, borrowing books from a local library and the free Amazon cloud storage that comes with your purchase. But similarities aside, what are the major differences between the Kindles? And which one is right for you?

Amazon Kindle Fire

The Amazon Kindle is one of the hottest gifts for this holiday season, but if you're looking to buy one, it might be daunting to decide which is right for you. Should you get the Kindle Fire, the Kindle Touch, the Kindle Keyboard or the basic Kindle? 

We've broken down the Kindle by type - Basic Kindle, Kindle Touch, Kindle Keyboard and Kindle Fire - and then took a look at a few major differences to help you choose which Kindle you should call your own.

The Kindle by Type
Kindle Basic
The basic Kindle is not only the cheapest e-reader on the market, but it's simple, light and easy-to-use. If you're looking for a no frills reader that will practically pay for itself after a dozen book purchases, the basic $79 Kindle is the way to go.
It's less than 6 ounces, fits in your pocket, has built in Wi-Fi, a one month battery life, and has simple buttons that will make the interface easy to navigate. The screen is 6 inches of e-ink goodness and the Kindle can store around 1,400 books (2 GB), including access to Amazon's free cloud storage.  
If you plan to do a lot of typing or note-taking you may want to reconsider the basic alternative, because typing on this Kindle can be taxing without a keyboard.

Kindle Touch
The Kindle Touch is the newest addition to the family. The Touch is still an e-ink reader, but has a touch screen and only one "home" button. You can turn a page by tapping anywhere on the screen.
The Touch is $99 for the Wi-Fi only version and $149 for 3G. The Touch has a 6 inch e-ink screen, can go two months without a charge, has 4GB of storage and Amazon's free cloud storage and weighs less than 8 ounces.
The Touch is unique in that it has a new X-Ray feature, which allows you to look up characters, historical figures, or interesting phrases by tapping a word. Readers can access detailed descriptions from Wikipedia and Shelfari, Amazon's encyclopedia for book lovers. The Touch also has audio capabilities and can read books aloud to you.

Kindle Keyboard
The Kindle Keyboard is mainly targeted at readers who plan on taking extensive notes or like the ease of having an accessible keyboard. This Kindle is the only one that does not require readers to use a keyboard on screen.
Both the Kindle Keyboard with Wi-Fi only and the 3G alternative are $139. The Keyboard is slightly heavier and larger than its smaller counter-parts, but the screen is the same 6 inch e-ink reader. This version can also hold 4GB of books, lasts for two months on one charge, and weighs less than 9 ounces.
The Kindle DX, which is a big brother of the Keyboard, is ultimately the same model, but bigger with a 9.7 inch screen. It's over twice as heavy and over twice as expensive, but for readers looking for a bigger screen, the Kindle DX remains an option. The battery life of the DX is only 3 weeks.

The Kindle Fire
The Kindle Fire is very different from its cousins the basic, the Touch and the Keyboard. Although the Fire can be used solely as an e-reader, it's ultimately a tablet and can do much more. You can watch over 18 million movies, TV shows, use apps, play games, listen to songs, read books, newspapers, magazines and documents and listen to audiobooks.

The Fire is $199, comes with Wi-Fi, has a new Amazon Browser (Amazon Silk), sports a 7 inch LCD color touchscreen and weighs less than 15 ounces.
If you're looking for a multi-media machine, on par with the iPad 2 and other tablets, the Fire is for you. However, there can be some negatives to the Fire if you're looking primarily for an e-reader, which we outline below.

How to Choose Between Major Differences in Kindles
With or Without Special Offers
The "special offers" are ads that show up on the main screen of the Kindle and are your Kindle's background while the Kindle is sleeping. If you don't mind the distraction, then don't bother paying extra for a Kindle without the offers. In fact, many readers like the offers, which may give you discounts on books or other Amazon material. However, if you're easily distracted, or have no interest in seeing ads pop up on your home screen for mascara, spend the extra thirty bucks for an ads-free Kindle.

Our Vote: If you don't mind shelling out the extra cash, get the Kindle without the special offers.

3G or No 3G
All of the Kindles come with Wi-Fi and can be connected to your home network and open networks such as Starbucks. A free 3G Network is offered with the Kindle Touch 3G, the Kindle Keyboard 3G and the Kindle DX. A 3G Kindle is ultimately most useful for readers who travel frequently or would like to access and download material on the go. Because you can easily download a book (or one hundred) and store it on your Kindle, there are very few reasons the average person would need to be on the 3G Network. However, if you like to have the option of accessing the online store and downloading new material anywhere and at any time, the 3G is for you. The Kindle Fire does not come with a free 3G option, however you can join the AT&T 3G network by paying a monthly fee.
Our Vote: You probably won't need 3G.

At $79, the basic Kindle is by far the cheapest option. However, if you're interested in a more multi-media accessible experience, the Kindle Fire is the cheapest tablet on the market at $199 (less than half the iPad 2) and is definitely worth the price. In fact, Amazon seems to be selling the Fire at a loss.
Our Vote: The basic Kindle at $79 is the cheapest, but the Kindle Fire at $199 is the best deal.

Screen: E-Ink vs. LCD
The basic Kindle, Kindle Touch and Kindle Keyboard all have 6 inch, e-ink screens. (The Kindle Keyboard DX has a 9 inch e-ink screen.) E-ink is known to be easy on the eyes and is often considered the closest digital experience to reading on paper. However, e-ink means reading exclusively in black and white and it's impossible to read in the dark (so you'll need a reading lamp or clamp on light).

The Kindle Fire, on the other hand, has a 7 inch color LCD screen. It has a 1024 X 600 pixel resolution at 169 ppi, 16 million colors. The screen is sharp and beautiful for watching films, TV shows or playing video games, but will it hurt your eyes for reading? Most eye doctors say, no. LCD screens shouldn't harm your eyes, but they may make them temporarily drier if you aren't careful.
Reading on LCD screens is nearly impossible in direct sunlight because of the glare, but, on the flip side, you can read in the dark with no problem. Although the LCD screen on the Kindle Fire is bright, you can also adjust the brightness depending on how you're using the Fire and when reading you can change the background and font colors to what's most comfortable for you.
Our Vote: We're undecided.

If you plan to read a lot at the beach or for many hours at a time, you may want to stick with the classic e-inks. However, if you like to read in the dark and don't mind your computer screen, the color LCD offers more options.

What Kind of Material Do You Plan to Read?
If you're undecided about the screen type that works best for you, thinking about the type of material you hope to read on your new e-reader may help narrow the choices. If you plan to read predominantly books on the e-reader, the e-inks are significantly lighter and probably easier on your eyes in the long run.
However, if you plan to read magazines, children's books and newspapers, we highly suggest the Kindle Fire, because the color LCD screen will greatly enhance your experience. Since the Fire also has video and sound capabilities, you can have access to interactive content within a newspaper, magazine or book. Although many magazines and newspapers for the Kindle Fire at this point remain straightforward, we expect future developments will include a more interactive reading experience (as is already the case with the iPad 2).

Our Vote: The Kindle Fire gives you the most diverse reading experience, however if you know you only want to read books, then stick with an e-ink Kindle.

Play Sound file without importing winmm.dll or microsoft.visualbasic.dll

Q.) I am writing a program using Delphi prism. The goal is to be able run on windows and linux (mono) from the same project. So, at this point I need to have a way of playing a sound file for windows and linux(mono) without having to import winmm.dll or microsoft.visualbasic.dll.
Since I need this to work on mono also, I don't want to use visualbasic.dll. In the past, it gave me all kinds of issues.
Are there ways to play sound file without using these dll files?

No matter how the soundplayer is instantiated and used, it always works fine under windows OS, whereas on Linux under mono it sometimes plays and other times it just won't play at all.

First Version:
  var thesound := new SoundPlayer;

if Environment.OSVersion.Platform = Environment.OSVersion.Platform.Unix then
.SoundLocation := '/sounds/Alarms.wav'

Second Version

var sp := new SoundPlayer(new FileStream("/sounds/Alarms.wav", FileMode.Open, FileAccess.Read, FileShare.Read));
A.) You can use System.Media.SoundPlayer. This is implemented by Mono. 

What is the difference between System.Windows.Point and System.Drawing.Point namespace?

Q.) I want to draw a line using controlpaint.DrawReversibleLine method and tried to pass, but it wants system.drawing.point input. I am little confused. What are the differences between them? Or How are they different besides the noticeable differences?

A.) System.Windows.Point is a WPF structure, whereas System.Drawing.Point is a WinForms structure. In general, if you're writing a WinForms app, the don't use stuff from any of the System.Windows namespaces (except System.Windows.Forms). The resources in these namespaces are WPF specific, so unless you intend to interface WPF and WinForms, it would be best to avoid them.

Other answers:
  • System.Windows.Point is intended for WPF applications.
    The System.Windows namespaces contain types used in Windows Presentation Foundation (WPF) applications, including animation clients, user interface controls, data binding, and type conversion
  • System.Drawing.Point is intended for WinForms applications.
    The System.Drawing namespace provides access to GDI+ basic graphics functionality.

Google TV 2.0 is all bling and no kerching

Google TV

Sill picking up pieces from hype bubble burst

It is easy to be rude about Google TV, but at the back of the mind is the feeling that one day, after successful tinkering, Google may get it right. Yet after initial hype and excitement around the launch, Google has struggled to recover from the dead weight of unfulfilled expectations that followed, and it will take something more than the recent revamping including an improved user interface to regain any sort of momentum.
It is little surprise that Google's actual announcement was overshadowed by the vapourware of speculation around Apple's impending TV launch expected sometime next year. That has been pitched as Steve Jobs' final legacy since he is said to have claimed to have solved the riddle of the connected TV shortly before he died. This is exactly what Google has also been trying and, so far, has failed to do.

Indeed part of the re-launch dubbed Google TV 2.0 is a plan, as yet undated, to launch around 100 new video channels on YouTube designed more for the big screen. These will be fed with supposedly original content from media outlets, and celebrities such as Madonna and Jay-Z.

But while YouTube can provide in effect a ring-fenced section containing content of high technical quality, the announced plans highlight the continuing dilemma for Google TV. That is how to attract truly premium content, and to persuade all the players of the ecosystem � notably smart TV makers � that it is worth participating in the venture.

So far Sony makes Google TVs, while Logitech makes set-top boxes that enable existing TVs to connect to the service. Neither have been selling like hot buns, but it could be that ironically Intel has done Google a favour by pulling out of the smart TV market. Intel had been one of the key Google TV partners, alongside Sony and Logitech, and pulled out at least partly because the service had failed to generate sales of chips. Now Google is no longer shackled to the Intel chipset and may be better placed to replicate on TVs the success Android has already enjoyed on smartphones with implementations on a variety of chipsets.
Indeed Google started pulling smartphones towards its TV service under Android in June 2011 by acquiring Sage TV, a Californian maker of a DVR with Slingbox-style placeshifting. The plan was to integrate this into Google TV so that broadcast content could be accessed remotely on Android devices. In this way Google hopes even to stump up some deals with a TV bundled in. Some mobile operators are already giving away smart TVs with contracts.

There are hints of this in Google TV 2.0, which alongside simplified navigation includes a customised home screen via an Android app. There is also a new TV & Movies app allowing users to browse a library of around 80,000 movies and TV shows from Amazon as well as of course YouTube itself.

Google also announced that the market for TV apps will be opened up to developers via the Android Market, so that existing mobile apps will start being ported across to the TV.

While none of these announcements will lift Google TV's immediate fortunes, they do signify that Google still has its eye on the box.

New Materials Turn Heat Into Electricity

New Materials Turn Heat Into Electricity
New Materials Turn Heat into Electricity
A new material with a low-temperature nonmagnetic phase and a strongly magnetic high-temperature phase could potentially be used to help generate power
Most of today�s power plants�from some of the largest solar arrays to nuclear energy facilities�rely on the boiling and condensing of water to produce energy.

The process of turning heated water into energy was essentially understood by James Watt all the way back in 1765. Heat from the sun or from a controlled nuclear reaction boils water, which then expands, moves a turbine and generates power.

Why water? It is cheap; it absorbs a lot of �latent heat� as it turns into steam; it produces a lot of power as it expands through the turbine; and it is easily condensed back to liquid water using an environmental source such as a river.

Heat to electricity
Beginning from the fundamental research of Nicolas Leonard Sadi Carnot in 1824, engineers have learned how to manipulate the boiling and condensing of water, using this �phase transformation� between liquid and gas to generate electricity.

Adding heat to the water at the right point in the cycle and preventing heat exchange at other points during the cycle enables researchers to ultimately extract the most power from the steam. In this way, they carefully designed the cycle to maximize its efficiency, a mathematical concept that Carnot defined.
�This boiling and condensing of water requires massive pressure vessels and heat exchangers to contain the water,� said researcher Richard James, of the University of Minnesota.

James and his team of researchers want to substitute a completely different phase transformation to replace the boiling and condensing of water. They have been investigating that possibility using a family of metal alloys (specific mixes of different elements) called �multiferroic materials.�

Multiferroic materials
Multiferroic materials are materials that exhibit at least two of three �ferroic� properties: ferromagnetism (like an iron magnet, spontaneously magnetized), ferroelectricity (spontaneously developing two poles), or ferroelasticity (spontaneously strained). A natural way to exhibit ferroelasticity is by a phase transformation in which one crystal structure suddenly distorts into another, a so-called martensitic phase transformation.
Instead of water to steam, the James�s team�s idea is to use a martensitic phase transformation that occurs naturally in some of these multiferroic materials. Using a mathematical theory for martensitic phase transformations developed with National Science Foundation (NSF) funding, the researchers discovered a way to systematically tune the composition of multiferroic materials to be able to turn the phase transformation on and off.

Usually a metal�s ability to switch phases like this is impeded by a characteristic called �hysteresis,� which is how long it takes for the magnetism of the metal to catch up with the phase change. If it takes too long, it impedes the metal�s ability to switch phases back and forth.

Evolving alloys
�The key idea is to manipulate the composition of the alloy so the two crystal structures fit together perfectly,� James said. �When this is done, the hysteresis of the phase transformation drops dramatically and it becomes highly reversible.�

Even after the first low hysteresis alloys began to emerge, the strategy was all based on theory. �To be sure that the hysteresis dropped for the expected reason, it was critical that we actually see the perfect interfaces in tuned alloys,� James said.

For this purpose, James teamed with Nick Schryvers from the Electron Microscopy for Materials Science laboratory at the University of Antwerp in Belgium, a celebrated center for the study of phase transformations using electron microscopy. The resulting study, by Schryvers and University of Antwerp graduate student Remi Delville, revealed perfectly matching interfaces between the two phases.

Heusler alloys
The researchers pursued the concept in a family of alloys called Heusler alloys which are magnetic, even though the metals that make them up aren�t. Named for the German mining engineer Friedrich Heusler, who first noticed that Cu2MnSn (copper-manganese-tin) is magnetic even though the separate elements Cu, Mn and Sn are nonmagnetic, this family of alloys has a striking propensity to exhibit magnetism. As James notes, Heuslers are also loaded with martensitic phase transformations.

Working in James� group, postdoctoral fellow Vijay Srivastava applied the strategy to achieve low hysteresis, systematically changing the composition of the basic Heusler alloy Ni2MnSn and arriving at Ni45Co5Mn40Sn10.

�Ni45Co5Mn40Sn10 is a remarkable alloy,� said James. �The low temperature phase is nonmagnetic but the high temperature phase is a strong magnet, almost as strong as iron at the same temperature.� The researchers immediately realized that such an alloy could act like the phase-transitioning water in a power plant.
�If you surround the alloy by a small coil and heat it through the phase transformation, the suddenly changing magnetization induces a current in the coil,� said James. �In the process, the alloy absorbs some latent heat. It turns heat directly into electricity.�

Revolutionizing power plants
The consequences for the technology are potentially far-reaching. In a power plant, one would not need the massive pressure vessels, piping and heat exchangers used to transport and heat water. Since the transformation temperature can be adjusted over a wide range, the concept is adaptable to many sources of heat stored on earth with small temperature differences.

�One can even dream of using the temperature difference between the surface of the ocean and a few hundred meters down,� James said.

Together with Professor Christopher Leighton at the University of Minnesota, the researchers are also studying the possibility of making thin film versions of their devices. Those could work in computers, right on the chip, to convert waste heat into electricity to charge the battery.
James emphasizes that their demonstration is just one of many ways one can use martensitic phase transformations for energy conversion.

�Besides magnetism, there are many physical properties that could be different in the two phases and could be used to generate electricity from heat,� James said. �But how to develop these concepts and which ones will work best?�

�Even the criterion for �best� is unclear, since one does not pay for waste heat,� James continued. �Really, we have to rethink from fundamental principles the thermodynamics of energy conversion at small temperature difference.�

Sapphire Pure Black X79 Motherboard Shows Off

Sapphire Pure Black X79
Sapphire Pure Black X79 Motherboard

Since a number of X79 motherboard were already previewed, it was only a matter of time before Sapphire leaked one of its own, so the Pure Black X79 definitely didn't go by unnoticed.

Then again, this isn't so much a formal preview on the company's part as it is an unofficial photo shoot, of sorts, carried out by VR-Zone. The X79 Express Chipset may or may not be supplemented by a PCI Express bridge chip.

The CPU socket is wired to four DDR3 memory slots, which means that up to 32 GB of RAM can be in a system at any one time,(4 x 8 GB).

Also, six PCI Express x16 slots are present, of which three are x16 electrical.

CrossFireX setups should be easy to set up (multi-GPU AMD card configurations), though SLI (NVIDIA) doesn't seem to be on the list of supported features.

The list goes on, though, with a significant degree of thoroughness as far as expansion capabilities go.

In addition to four SATA 6.0 Gbps ports (SATA III), Sapphire threw in the same number of SATA 3.0 Gbps connectors (SATA II).

Meanwhile, the back panel has a pair of eSATA connectors and four USB 3.0 ports (two more are available as headers on the motherboard), plus Bluetooth, 7.1 channel audio and dual Gigabit Ethernet.

Other specifications include UEFI BIOS, a debut LED, Power, Reset and Clear CMOS buttons, voltage read points and an active cooler on the chipset.

Like all the other X79 platforms, the Sapphire Pure Black X79 (obviously, it gets the name for the PCB) will reach stores in a week or so.

While the Intel Sandy Bridge-E CPUs will get to stores around mid-November, 2011 (14-15), the LGA 2011 motherboards should show up and start competing a bit sooner. Unfortunately, no price was mentioned.

Chrome Remote Desktop Extension makes screen sharing free and easy

Chrome Remote Desktop Extension

When word gets out that you�re tech-savvy, you tend to get asked for help a lot. Helping people out can mean a lot of time spent on the phone, or driving over to someone�s house. That�s why having software that allows you to remotely control someone�s computer is a life saver. And now it seems you can do it from right within your web browser.

Google recently released the Chrome Remote Desktop Extension, which, as you can imagine, allows you to remotely control someone else�s computer. All you need to have them do is install the extension (assuming you already had them install Chrome), and have them click a button to generate an access code. They can then give you the access code over the phone, or in an instant message. After that, you�re all set. While this might not be the most robust screen sharing software out there, it does have one feature that you�ll be hard-pressed to find elsewhere. It is completely free to use, both privately and commercially.

Apple Acknowledges iOS 5 Battery Life Drain, Issues Beta Update to Devs

Apple fesses up to battery woes with iOS 5

Apple fesses up to battery woes with iOS 5

Many Apple customers using iOS 5 compatible devices have been complaining of poor battery life after upgrading to latest version of Apple's mobile operating system. A thread over on Apple's own support forums regarding poor battery life on the new iPhone 4S has reached 215 pages and has over 3,200 replies.

Interestingly, numerous suggestions have been given by users and pundits to improve battery life including turning off Wi-Fi and Bluetooth, disabling iCloud synchronization and some aspects of Location Services, and cutting down on alerts that appear in iOS 5's new notification center. However, disabling all of these features seriously cripples what is supposed to be one of the premiere mobile operating system on the market.

Now after weeks of silence, Apple is acknowledging that iOS 5 does in fact have a problem with battery life. Or rather, Apple in its typical language explains in a statement to the Wall Street Journal's Ina Fried that a "Small number of customers" were experiencing battery life problems. Whenever Apple encounters a problem with one of its products, this is typically the "scope minimizing" statement that it likes to release. The company goes on to explain, "We have found a few bugs that are affecting battery life and we will release a software update to address those in a few weeks."

Apple fesses up to battery woes with iOS 5
While customers may have to wait a few weeks to receive the update, developers have already been issued a beta of iOS 5.0.1 that corrects the battery life drain (among other updates). The release notes including with the beta state that the following issues have been addressed:
  • Fixes bugs affecting battery life
  • Adds Multitasking Gestures for original iPad
  • Resolves bugs with Documents in the Cloud
  • Improves voice recognition for Australian users using dictation
  • Contains security improvements
  • iOS 5.0.1 beta introduces a new way for developers to specify files that should remain on device, even in low storage situations 
For the time being, iOS 5 users that are having battery life issues can follow this guide to crippling your device to reclaim some runtime until the fix is released.

Opera Mobile 11.5.2 and Opera Mini 6.5.1 for Android Now Available for Download

Opera web browser for Andriod

Enlarge picture Opera had a very busy week, as the company pushed lots of new major updates for all mobile platforms available on the market.

No later than yesterday Opera Software announced the availability of its new Opera Mobile 6.5 for BlackBerry, iOS, S60, and J2ME, as well as Opera Mobile 11.5 for Symbian S60 devices.

Although Android fans got their Opera Mini 6.5 version more than two weeks ago, it looks like the developers decided to push another update for both its

Android mobile web browsers, Opera Mobile and Opera Mini.

According to Opera Software, the Opera Mini 6.5.1 for Android devices is now available for download in the Android Market, and later today via developers' servers.

The latest version of Opera Mini for Android corrects several bugs, and brings some crash and stability fixes:

- Fixed problem with importing system bookmarks on some devices;
- Fixed problems with no feedback given to the user when shortcut couldn't be added to home screen;
- Fixed problems with star indication of bookmarked pages after device restart ;
- Fixed problems with download view not updated properly in some cases

Furthermore, the Opera Mobile 11.5.2 for Android update contains a lot more bug fixes, as well as a mjor change in Opera's behaviour.

Basically, a new enable/disable option that would block (or not) pages from redirecting to themselves.

According to Opera, redirecting webpages to themselves was causing site compatibility issues, so now it's been changed and users can bring the old behavior back from opera:config and enabling �Disable Client Refresh To Same Location�.

Other changes added with Opera Mobile 11.5.2 for Android include:

- Fixed problems with settings menu closing without user interaction;
