Sony shows off its Android tablets

Sony offered the press a glimpse of its upcoming S1 and S2 tablets, which will enter an already-crowded market at an unannounced point later this year. Both run Android, but the S1 features a single 9.4-inch display, while the foldable (and pocketable) S2 features a hinge connecting a pair of 5.5-inch screens.

In a July 13 interview with CNBC , Sony Electronics president and COO Phil Molyneux explained that the S1 has an "off-center gravity point so it balances in your hand" and a "unique wraparound design." He then demonstrated both tablets, which are capable of syncing to Sony's e-reader, music and video hubs, but shied away from questions about pricing and exact release dates.

Sony's S1

The S1 will appear in the fall timeframe, with no supporting carriers mentioned so far for that device (both tablets are 3G/4G- and WiFi-compatible). Meanwhile, Sony did say AT&T will be the exclusive carrier of athe 4G-capable S2 in the United States, once the tablet is released sometime this year.

Sony had previously hinted at the device's capabilities in a short video that was high on whimsy and low on actual product detail. In April, the company offered a preliminary glimpse of the tablets, positioning its relatively late entrance into the market as a strategic move. "If I want to differentiate [our tablet] from others, do I release it tomorrow, or do I wait until I differentiate it?" Sony CEO Howard Stringer told Reuters at the time.

Sony was apparently toying with the idea of introducing 3D to the device. "Android 3.0 is a new version of the Android platform with a new holographic user interface that is designed from the ground up for devices with larger screen sizes, particularly tablets," Google Senior Vice President Andy Rubin wrote in a quote shoehorned into Sony's April announcement.


Sony's S2
(Click to enlarge)

According to a hands-on report from Engadget, the S1 and S2 certainly don't have 3D displays, but they do run Android 3.0 and have PlayStation gaming capabilities. The S1 is novel, however, in featuring a wedge profile designed to mimic a folded magazine, while the even-more-unusual S2 folds up and is capable of fitting into the breast pocket of a sport coat.

We additionally learned via Tweets by Technologizer editor Harry McCracken that the S1 and S2 will both feature Quick View, claimed to enable faster loading of web pages, plus software optimized for smooth scrolling. The S1 will include an infrared port so it can control TVs, McCracken adds.

In addition to the bestselling Apple iPad, the tablet market has become increasingly crowded over the past few months with Android-powered offerings from the likes of Samsung, Motorola and others. Meanwhile, rather than embrace the Android army, Research In Motion and Hewlett-Packard have released tablets running proprietary operating systems. Microsoft is planning for the next version of Windows, code-named "Windows 8," to appear in a tablet edition.

Among all those competitors, it remains to be seen whether Sony can establish a presence for itself.

GIMP ( GNU Image Manipulation Program ) for Linux

GIMP is an acronym for GNU Image Manipulation Program. It is a freely distributed program for such tasks as photo retouching, image composition and image authoring.

It has many capabilities. It can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc.

GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be easily scripted.

GIMP is written and developed under X11 on UNIX platforms. But basically the same code also runs on MS Windows and Mac OS X.

It's very likely your Linux distribution already comes with a GIMP package. It is a preferred method of installing GIMP, as the distribution maintainers take care of all the dependencies and bug fix updates.

Ubuntu, Debian

Ubuntu or Debian users can simply run

apt-get install gimp

to get the latest stable release of GIMP.

openSUSE

SUSE users can install GIMP by running

yast -i gimp or zypper in gimp

depending on the distribution version.

Fedora

Similarly to the above, Fedora users can install the latest stable GIMP by running

yum install gimp

Mandriva

Mandriva Linux users can install the latest stable GIMP by running

urpmi gimp

GIMP ( GNU Image Manipulation Program ) for Linux

GIMP is an acronym for GNU Image Manipulation Program. It is a freely distributed program for such tasks as photo retouching, image composition and image authoring.

It has many capabilities. It can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc.

GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything. The advanced scripting interface allows everything from the simplest task to the most complex image manipulation procedures to be easily scripted.

GIMP is written and developed under X11 on UNIX platforms. But basically the same code also runs on MS Windows and Mac OS X.

It's very likely your Linux distribution already comes with a GIMP package. It is a preferred method of installing GIMP, as the distribution maintainers take care of all the dependencies and bug fix updates.

Ubuntu, Debian

Ubuntu or Debian users can simply run

apt-get install gimp

to get the latest stable release of GIMP.

openSUSE

SUSE users can install GIMP by running

yast -i gimp or zypper in gimp

depending on the distribution version.

Fedora

Similarly to the above, Fedora users can install the latest stable GIMP by running

yum install gimp

Mandriva

Mandriva Linux users can install the latest stable GIMP by running

urpmi gimp

Installing Linux (Keeping Windows)

If you have been using Windows for any length of time you will have acquired some expertise and probably built up a collection of files you don't want to lose, two reasons why you might think moving to Linux is going to be too much trouble. It isn't, trust me and read on...

Dual booting

It is really quite simple to install two operating systems on a single PC, then use a piece of software called a 'boot manager' to choose which to load when you start the computer. Microsoft's boot manager only gives you one option, to boot Windows, but most Linux distros include the 'Lilo' or more often these days 'Grub' boot manager which is quite happy to let you choose from a list of operating systems, including Windows.

Partitioning

A hard disk, or for that matter a floppy, can be divided into several sections called partitions (just like you might partition a big office to make several smaller ones). Each partition is then formatted with whatever file system you want to use, and they don't have to be the same. Generally Windows PCs only have a single partition, though some manufacturers now make a 'restore partition' where they store a backup copy of Windows and their original software bundle in case you need to re-install.

If you are going to be dual booting you will need at least 3 partitions, one for Windows (which might use FAT32 or NTFS formatting), one for the Linux OS and one for 'swap' which is used by Linux as temporary memory rather like 'virtual' memory under Windows. Linux can use various formats, ext2 is common for swap, and can be used for the main bootable partition too, though ext3 or reiserfs are more common. If all this sounds complicated, don't worry the installer supplied with your distro will take the strain. Once partitioned your disk will appear to Windows to have shrunk, Windows simply doesn't recognize the existence of file systems other than its own. Linux is more accommodating and will recognize, and make use of, a wide range of file systems.

Resizing

A few years ago most distros included a partitioning tool which would assess how much space was on your existing Windows disk, and suggest how much it would be safe to give over to Linux. If you checked 'Agree' it then re-sized the Windows partition and re-formatted the freed space for Linux. This worked very reliably with Windows 95, 98 and ME that used the FAT 32 file system, but not so well on NTFS which is normally used by Windows 2000 and XP.

Possibly because of this, or maybe because Microsoft have been grumbling about infringement of the copyright they hold on their file systems, resizing tools have disappeared from most distros, but are still available as separate applications. Whilst you are still in the proprietary software world you might like to buy Norton Partition Magic which is reckoned to be very good. Or you could take your first tentative step into the world of Open Source Software by downloading 'GParted' (Gnome Partition Editor) from Sourceforge.

Gparted is supplied as a small (30MB) .iso image file ready to burn to CD-R (or -RW) to make a bootable CD. Do that and put it to one side for a moment...

Housekeeping

Though GPArted is good, nothing in this life is certain, especially where computers are concerned, so some basic precautions are required. First, a backup of everything you would hate to lose if the partitioning goes wrong. Check that you have the necessary disks to re-install Windows and any Windows software you want to keep using too. If you have them you probably won't need them, but if Gparted fails (or you mess up and make the wrong choices) you'll be glad you've got them. Make a note of settings for Internet dialers, ADSL modem settings, POP3 accounts, SMTP accounts and passwords for everything. It's a good idea to export Internet bookmarks and your email address book too. Then defrag the disk, this makes the re-sizing and partitioning much quicker and more reliable. When you sure you've checked everything, put the Gparted CD in the drive and reboot.

Booting

Your computer may, or may not, be set to boot from the CD/DVD drive. If you're not sure, just wait, if it goes straight into Windows as normal, it isn't. So reboot again and this time watch the screen closely until you get a message from the BIOS along the lines of, 'To Enter Setup...' then do what it says – usually it is 'Hit Escape' or 'Hit Del'. Do it and in the BIOS setup set CDROM as the first boot device. Save settings and exit the BIOS Setup. This time your PC will boot from the GParted CD.

Gparted actually loads a simple version of Linux into RAM, so you will see a lot of unfamiliar messages telling you what's happening, you can ignore them until you get to the 'Select your language' screen. Choose whatever you prefer and then you move onto choosing a keyboard layout. Do that too and you'll be asked to choose the X-server type.

If you've never used Linux before this might seem weird, so a brief digression is in order. 'X' is the graphics system used by most versions of Linux. It drives your screen (via your graphics card) your keyboard and your mouse. The X-server provides services to other software such as window managers and applications. These days fully featured distros use a version of X from Xorg, but it uses a lot of resources so you could choose the simpler Xvesa instead. Next choose your preferred screen resolution and color depth (the defaults will probably be sensible). After a brief pause the Gparted screen pops up.
