Windows 8 Release Preview

2012-06-02T00:59:00.003-07:00

Windows 8 is an upcoming version of Microsoft Windows, a series of operating systems produced by Microsoft for use on personal computers, including home and business desktops, laptops, Microsoft Tablet PCs, and Home theater PCs. According to unofficial sources, the release date for Windows 8 has been set for October 2012, three years after the release of its predecessor, Windows 7. Windows 8's server counterpart, Windows Server 2012, is in development concurrently with Windows 8. The most recent official pre-release version of Windows 8 is the Release Preview, which was released on May 31, 2012.

Unlike Windows 7, which was intended to be a more focused, incremental upgrade to the Windows line, Windows 8 has been "reimagined from the chipset to the user experience" to connect more with the user. It features the Metro interface that is designed for touch screen input similar to that in Windows Phone and on the Xbox 360. A version of Windows 8, called Windows RT, also adds support for the ARM processor architecture in addition to the previously supported microprocessors from Intel and AMD.

CentOS 5.8 Officially Released.!

2012-03-08T19:24:00.002-08:00

Hey guys
finally here is another release of linux operating system now this time it is CentOS .

About CentOS 5.8

CentOS is a community enterprise operating system, based on the Red Hat Enterprise Linux sources and

available for the following architectures: Intel 32-bit, Intel IA-64 (Itanium 64-bit), 64-bit (AMD's AMD64

and

Intel's Intel 64). Additionally, CentOS is a 100% free Linux distribution fully compatible with Red Hat

Enterprise Linux.

CentOS 5.8 is available as an installable DVD ISO image (see download link at the end of the article) for

both 32-bit and 64-bit architectures and it is based on the upstream release of Red Hat Enterprise Linux

5.8.

Released within a week from the Oracle Enterprise Linux 5.8, the CentOS 5.8 distribution contains lots

of updated packages, bugfixes and new functionality.

As usual with a new CentOS release, this one also includes packages from all Red Hat Enterprise Linux

variants, including Client, Server, Clustering and Virtualization. The upstream software repositories have

been combined into a single one for this release, helping end users to work easy with it.

Existing CentOS 5.x users can upgrade to the new CentOS 5.8 release via YUM, running the "yum update"

command in root terminal window.

"Upgrading from CentOS-5.7 ( or CentOS-5.0/5.1/5.2/5.3/5.4/5.5/5.6): If you are already running

CentOS-5.7 or any older CentOS-5 version then all you need to do is update your machine via yum

by running : 'yum update'"

"Running 'yum list updates' before doing the update is recommended, so you can get a list of

packages that are going to be updated." - said Johnny Hughes in the official release announcement.

Moreovoer, the CentOS 5.8 operating system was completely rebuilt using a brand-new build system and

library checks, in order to confirm Red Hat Enterprise Linux binary compatibility.

Android Users: Here's Some Advice to Protect Your Phones

2012-03-06T23:47:00.005-08:00

Android smartphone users can take some common sense precautions to protect their personal data from being stolen -- important advice considering an app developer purports to know how to take the information in under 60 seconds.

Loredana Botezatu of BitDefender, a cybersecurity software maker, recommends:

Never lose sight of your smartphone in public.
Keep a close eye on what a person is doing with your phone if you lend it to someone.
Install mobile anti-malware software on your phone.
Don't store job-related information on your phone unless it's encrypted.

The advice comes as a gray hat app developer has released into the wild five tools purportedly for "study purposes" that can clean out all the data on an Android smartphone in less than a minute.

Based on information from virus researchers at BitDefender, here's how the tools work.

When any of the apps is loaded on a victim's phone, they can be activated remotely by a cyber thief. Once activated, it sends a five digit pass code to the phone's intruder and secretly uploads the device's contacts, messages, recent calls, and browser history into the developer's space in the Android Cloud. After copying the data from the phone, the apps uninstall themselves so a target won't know they were even on their mobile.

To obtain data sucked from a phone, a Net crook need only travel to the developer's cloud location, enter the five-digit code generated by their copy of the app and for $5 they can download all the data nicked by the sinister software.

In an ironic twist, the developer has posted a notice at their site informing users of the apps that if they don't pay for the data they've stolen within 24 hours of the theft, all the information will be erased from the site "out of respect and for security reasons." "[N]eedless to say...this statement is by no means to be trusted," Botezatu cautions.

This latest attack on Android phones is just one of many this year. In fact, the phones are seen as a ripe target for mobile miscreants. According to a report released by a cybersecurity software maker in August, attacks on Android by malware writers jumped 76 percent over the previous three months, making it the most assaulted mobile operating system on the planet.

Some of that malware has been devilishly clever. For example, a bad app called Soundminer listens to conversations on an Android phone and is able to recognize when a credit card is spoken. After identifying such a number, it snips it from the conversation it has been recording and sends it to a Web baddie.

While cyber sorties like these may give some smartphone buyers pause before picking up an Android mobile, some commentators believe the benefits of an open system like Android outweigh those of systems with less openness and less vulnerability to attack. "Threats are everywhere," JR Raphael wrote in PC World. "The answer isn't locking down the world; it's taking basic precautions."

Google Expands Android App Size from 50MB to 4GB

2012-03-06T23:43:00.003-08:00

Google is giving Android app developers a lot more room to work with, expanding the maximum Android app size from 50MB to 4GB.

Although Android apps were free to exceed the size limit before, developers had to host the data on their own. For users, that meant downloading additional files from within the app after installing the core app from the Android Market. The extra downloads were a nuisance and would eat into the 15-minute refund window for Android apps.

Under the new system, Android .APK files will still be limited to 50MB, but Google will host up to two expansion files, each up to 2GB. Most newer devices will download these expansions automatically, and the refund window will not begin until all files are in place.

Some older devices will still have to use a separate downloader, but Google now offers its own developer tool for this purpose. This tool can download files in the background, resume large files safely, pause and resume based on Wi-Fi availability and notify users of estimated completion time. If you've ever put up with extra file downloads in games like Gun Bros. and Asphalt 6, the prospect of a more user-friendly should come as a relief.

In both cases, users will be able to see the total size of the app from within the Android Market, solving another issue with app developers' own download tools.

Although most apps don't have troubling coming in under 50MB, size limits are a big concern for game developers, who need to pack their apps with image and video assets. As phones and tablets move toward higher-resolution displays, the need for larger apps will only grow.

Google Augmented Reality Glasses Expected by Year's End

2012-03-06T23:19:00.003-08:00

Google is working on pair of augmented reality glasses running on Android, set for release later this year, according to the New York Times, which quoted unnamed company employees. The glasses are meant to work like a heads-up-display that analyzes and displays information for the wearer, priced somewhere between $250 and $600.

The Google glasses are reportedly based on Android and will also have a 3G or 4G data connection along with several sensors, including GPS and motion. Earlier reports on the technology from 9 To 5 Google also indicate there will be a few buttons on the arms of the glasses, but otherwise, they could be mistaken with regular thick-rimmed eyewear, similar to Oakley’s Thump sunglasses with a built-in MP3 player.It appears there will be only one display in the glasses (for one eye), which won’t be transparent. The navigation system sounds interesting: you would be able to scroll and clock through menus by tilting your head -- but this could be quite weird when you are in a public space, navigating through the glasses menus, tilting your head back and forth.Some other reported technology in the glasses would be Google Latitude to share location and the Goggles service to search images and identify what the wearer is looking at, while Maps would show you things nearby. Unlike smartphones, the results from these searches would be overlaid on top of the real-time video feed from the glasses camera (augmented reality), but it’s still unclear whether the glasses would be an independent gadget, or if they would be tied to a smartphone for data connectivity, which wouldn’t require a separate data plan for your smart glasses.

Get Access Into Registration-Required Sites Without Need To Register

2012-03-05T06:21:00.000-08:00

Hey guys
you must have access the problem of registrations on some of the sites due to which you have to first registered on the site then you have to proceed further on that site.

I have a simple method to get access to protected content without need to endure the annoyance of signing up for an account. Every time relatives and friends send me links to registration-required Web sites, I’ll visit BugMeNot to bypass most of these annoyance. BugMeNot is a free Web site that stored registered user account logins and passwords so you don’t have to provide your personal info.

Once you at BugMeNot front page, just type in the URL of the website that you’d like access. BugMeNot then will return a list of user names and passwords along with their accuracy percentage.
For Firefox users, BugMeNot provide the extension that automates these process. Once you’ve installed the extension, you can easily access the website you like by right click on the username or email address text box.

Windows 7 to Mac OS Transformation

2012-03-04T22:17:00.002-08:00

For Windows 7:

For applying Mac OS X Theme through Visual Styler and True Transparency on Windows 7, you will be needed:

UXTheme Patcher
Mac OS X Leopard Visual Styler Theme
Left Sider (for moving minimize, maximize and close buttons to the left)

Instructions:
- Instructions are inside the zipped folders.

WINDOWBLINDS 7

WindowBlinds 7 is a third party freeware for applying Mac OS X theme and other interesting themes on XP. MSStyler Theme is not a perfect match of Mac Leopard, many of the visual features are missing, for e.g., the close, minimize and restore buttons are given on right hand side of title bar, instead of left hand side; menus and taskbar are not transparent; etc. WindowBlinds gives you almost a 100% result in changing the looks of windows to Mac OS X Leopard. Besides this, you can also add transparency effects to your windows and change the colors of the windows (only in full version). And most important, you don’t have to play with your Windows XP/7’s original files.

Linux Mint 12 KDE RC released!

2012-01-29T10:10:00.000-08:00

Blue Systems is a German company sponsoring Free and Open Source projects such as Netrunner and KDE-projects like kcm-gtk-config. As part of the partnership, Linux Mint will share its knowledge and expertise with Netrunner and both distributions will work together on improving their respective KDE editions. Although Netrunner and Linux Mint KDE offer a different

Installation

Installation of Linux Mint is generally performed with the Live CD. The Linux Mint OS can be run directly from the CD (albeit with a significant performance loss), allowing a user to "test-drive" the OS for hardware compatibility and driver support. The CD also contains the Ubiquity installer, which can guide the user through the permanent installation process.

The main edition of Linux Mint is available in 32-bit and 64-bit. Installation CD images can be downloaded, or installation CDs purchased from 3rd party vendors. Linux Mint can be booted and run from a USB Flash drive, with the option of saving settings to the flash drive. This allows a portable installation that can be run on any PC capable of booting from a USB drive. The USB creator program is available to install Linux Mint on a USB drive.

A Microsoft Windows migration tool, Migration Assistant, can be used to import bookmarks, desktop background (wallpaper), and various settings from an existing Windows installation into a new Linux Mint installation.

The Windows installer "Mint4Win", is included on the Live CD and allows Linux Mint to be installed from within Microsoft Windows. The operating system can then be removed similar to any other Windows software using the Windows Control Panel. This method requires no partitioning of the hard drive. It is only useful for Windows users; it is not meant for permanent installations because it incurs a slight performance loss.

About DebEX-Mint 12 Xmas with KDE 4.7.3 and kernel 3.1.4

DebEX-Mint 12 Xmas Live DVD is a remaster of Linux Mint 12 - codenamed "Lisa" released on 26 November 2011. The original system includes the Desktop Environments Gnome 3.2, Gnome Classic (Gnome 2.32) and Mate (a fork of the venerable GNOME 2 Desktop Environment). In DebEX-Mint 12 Xmas Edition, I have installed KDE 4.7.3 (latest stable version), as an alternative, so that everyone on the spot (during live operation) can compare the different Desktop Environments. I have replaced the original kernel 3.0.0-12-generic (the same kernel as in Ubuntu 11.10) with "my" kernel 3.1.4-exton-xmas-custom. Kernel 3.1.4 is the latest available stable kernel, which can be downloaded from kernel.org. The system language is English.

Why has the kernel been replaced?
Latest Ubuntu (11:10) and Linux Mint 12 original uses kernel 3.0.0-12-generic. There has been added a lot of different kinds of hardware support etc. in the latest stable kernel 3.1.4. So if you have acquired new hardware, which is not supported in Ubuntu 11.10 and/or Linux systems based on Ubuntu 11.10 it might be worth testing DebEX-Mint 12 Xmas. There is, among other things, support for brand new USB devices, like printers and cameras, etc. Odd support: Wii (which is not supported in Ubuntu's latest kernel 3.0.0-12-generic).

Program content etc
Among many other programs LibreOffice, Thunderbird, Firefox, Wicd, Brasero, VLC, Gimp and win32 codecs. In addition, Java and all necessary additions in order to install programs from source. All programs have been updated to the latest available stable version as of 7 December 2011. See a complete list of all installed programs HERE.

DOWNLOAD
The ISO file (debex-mint-12-special-kde-gnome-1460mb-111207.iso) can be downloaded from the Swedish Linux Society's server.

DebEX-Mint 12 Xmas can also be downloaded from Sourceforge.net - Fast, secure and free downloads from the largest Open Source applications and software directory.

How to Send E-mail from Facebook

2012-01-29T04:52:00.000-08:00

I have been using Facebook Messages to send email to few of my Facebook addict friends though they check their email accounts regularly but I know I’ll be getting my email reply soon when I send email from Facebook to directly into their Facebook Messaging inbox.

What is Facebook Message?
I don’t think I need to describe as we all use Facebook Messages to check – who have had messages us, each friend’s chats and text as well. Everything stores in Facebook Messages. You can check full conversation history including everything you’ve ever discussed with each friend as a single conversation. And to improve this, Facebook have added Email – Read, Write & Send Email. There’s no need to switch between Facebook and email accounts for your daily communication needs.

Send Email From Facebook Using Facebook Messages

To make it happen you need to get Facebook email address first, like – yourusername@facebook.com. If you still have not got, get it here.

Step 1) Once you get the Facebook email address, click on “Messages” which is next to Facebook logo and click on “Send a New Message”.

Step 2) One “New Message” window will pop-up on your screen right after you click on send a new message. Type email address into the To: box and content in Message: box.

Step 3) On clicking “Send” button Facebook will email your message to the respective email address. And like other email accounts you can att ach files using “Attach a File” button.

How to Switch To Linux

2012-01-29T03:07:00.000-08:00

Whenever you to think to install linux you probably think it would be nice and something different as compare to windows but for an hour you will get through the desktop themes installing new themes decorating your desktop but when the time come to work on the linux you prefer to switch on the windows because it made the task easier as compare to linux based operating systems.
There are literally thousands of apps related to linux in which whenever you want to install you to seek the information from the authentication user password you will have to enter whenever you want to access any data related .
Before you get started, you need to be prepared to be your own support system. While you can usually get help with Linux problems on different message boards on the web, before you do that, you need to make the effort to solve your own problems. Linux Drivers don’t have much sympathy for people who don’t make an effort to help themselves.

Things are much easier now than they were in the early days of Debian, Slackware, and Red Hat. Modern distrait such as Ubuntu and SUSE LED install with crucial applications (web browser, photo editor, email client, word processor, etc.) and support for most hardware out of the box. With Ubuntu, you can boot off the CD to determine whether or not your rig will work with the OS before you make a single change to the hard drive. You can tell if you’re going to have a problem before you hose your system, which is always a good thing.

Before we get started installing Ubuntu, feisty fawn, you’ll need to download the appropriate ISO file from the Ubuntu downloads page and burn it to disc. For neophytes, we generally recommend starting with the x86 versions, even if your CPU supports AMD64 extensions. The proper file name for most people will be ubuntu-7.04-desktop-i386.iso.

To burn the disc, you can use commercial burning software (like Nero) or download and install the free ISO Recorder software. It’s also a good idea to run a backup before you get started (or anytime you muck around with your partitions, for that matter).

The First Boot

Once you’ve burned the ISO, you’ll need to boot your PC from the Ubuntu CD, which will involve either manually selecting the optical drive or changing the boot order in your BIOS. After several minutes, you should see the basic Ubuntu desktop. You should have access to most of your hardware, including network, sound, and graphics. Some typical gaming components simply don’t have good Linux support—notably the X-Fi series of soundcards and GeForce 8800–family videocards. We’ll talk about them in a bit.

Install!

Assuming you booted into the live desktop properly, starting the install process is as simple as double-clicking the Install icon on the desktop. The install program will prompt you for your language, location, and keyboard layout before you get to the hard-disk partitioning section.

Choose the manual option when it comes time to partition your hard drive.

Partitioning your hard disk is the only step of the install process that has the potential to do serious harm. If you install to the wrong partition, you could accidentally nuke your Windows drive and all of its contents (that’s why we recommend running a full backup before you start the install process). The safest way to install is to add a new hard drive or just create free space on the disk—however, that’s not always an option. If you want to resize your existing partition, select the Manual option. Select the partition you want to resize and click Edit Partition. Then input the new size for the partition in megabytes (leave the other settings alone) and press OK. Next, you’ll need to create a swap partition. Highlight the newly created free space, click New Partition, set the size to 2,000MB, and choose Swap. Click your free space once again, then New Partition, and change the mount point to /. Leave the other settings alone and press Next.

If you choose to resize an existing NTFS partition, make sure you give your Linux install enough room. We used 120GB.

Now you’ll be prompted to import data from your Windows partition. The Ubuntu installer will pull your Gaim settings, Firefox bookmarks, music, photos, and documents over from your Windows install if you select these options. I had mixed results with this tool in the early build of Feisty—it crashed the installer on a few Vista machines we tested—but your mileage may vary. After you import files, you’ll be prompted to create a user account. You’re almost done!

The final step is to confirm your installer’s settings and press Install to finish the process. You’ll need to wait 20–40 minutes while the install completes and then finish by rebooting your PC and selecting the Ubuntu entry from the boot manager that was installed.

Using the Alternate Installer

If your machine won’t boot from the graphical install CD, either because you have a new videocard that’s not properly supported (GeForce 8800 series or newer) or you have an older unsupported chipset (notably the i915 integrated graphics), you’ll need to use the nongraphical installer, which is called the alternate installer, for your architecture. Download the correct alternate CD for your CPU (again from Ubuntu’s download page) and follow the prompts.

Connect to the Network

Getting your machine on the network is simple with Ubuntu, whether you use a wired connection or Wi-Fi. When you first boot, the only icon in your system tray at the top of the screen should be for networking. Simply click it, enter your SSID and WPA or WEP key (if necessary), and you’ll be on the network.

Finding and Installing Software

There are two ways to install programs on your new Ubuntu machine. The simplest is to use the Add/Remove panel, which lets you see all the software available to you from Ubuntu software repositories on the Internet. Most apps include a useful description, so if you search for Photo Manager, you’re sure to find some worthy candidates.

Sometimes you’ll need to fire up the more powerful Synaptic Package Manager, which you’ll find in System > Administration. After entering your password, click the Reload button to make sure the list of available apps is up to date. Synaptic provides a powerful search and easy filters that will help you find all the details of the applications installed on your system. You can see what apps are installed and which have updates available. If you want to update a single program to the latest available version, Synaptic is the easiest way to do that—just search for the software package, right-click it, and select “Mark for upgrade.”

You’ll occasionally need to add a new repository to your Linux install. A repository is just a server that contains software that’s configured and ready to run on your machine. If you want to install apps that aren’t included by default with Ubuntu, you’ll need to enable other respositories. To add a respository, you’ll need its apt line, which gives the software manager all the info it needs to access the repository (we’ll include some throughout this article). Open Synaptic and click Settings > Repositories. Go to the Third-Party tab and click Add; then type the apt line, exactly as it appears, in the window. Click Add Source, then click Close.

3D-Accelerated Videocard Drivers

There’s a lot of controversy surrounding the use of closed-source drivers for graphics hardware, but they’re the only option for 3D acceleration in Linux right now. The procedure for Nvidia and ATI hardware is a little different.

Install Nvidia GPU Drivers
Installing Nvidia’s closed-source 3D-accelerated drivers is easy with Feisty. Go to System > Administration > Synaptic Package Manager and search for the nvidia-glx package. Right-click the selection and select “Mark for installation.” You’ll be prompted with a list of dependencies, which you’ll need to approve for the application to work. Click Apply to download and install the app. Then open a new terminal (Applications > Accessories > Terminal) and run this command: sudo nvidia-xconfig –add-argb-glx-visuals; follow the prompts and reboot.

Install ATI GPU Drivers
Installing ATI drivers is a little more complex. First, you’ll need to disable the Composite option in your xorg.conf. Open a terminal and type sudo gedit /etc/X11/xorg.conf. In the gedit window, scroll to the section labeled Extensions and change the Option “Composite” line from “Enabled” to “Disabled”. Then in your already opened terminal window, type the following six commands:
