Time for Windows 7, Developers geeting Windows 7 RC next week (May ‘09)

Some Microsoft developers will be able to download a near-final version of the company's Windows 7 operating system, probably first week of May 09. 

Starting on April 30, MSDN and TechNet subscribers will be able to download the Windows 7 Release Candidate, Microsoft said in a blog post. Release candidates are typically feature-complete and stable, and suggest that the final version of a product will be available very soon.

The company recently posted information accidentally on its Partner Program Web site saying that the Release Candidate was already available to developers and would be released to the general public on May 5. That page was quickly pulled because the software was not yet ready. 

In its blog post Friday, Microsoft has now confirmed that the general public will be able to download the release candidate on May 5. 

Analysts have been predicting lately that the final release of Windows 7 will appear sooner than expected. Officially, Microsoft says that it is on track to deliver Windows 7 three years after the release of Vista, which was in January 2007. But some analysts now say it could be available in September or October this year.

HP Still Getting Heat on Nvidia Chips

Months after the issue first surfaced in the US, HP laptop owners continue to complain about defective Nvidia graphics cards that could cause laptops to fail.

Some customers say that they have been treated unfairly by HP, in part because their laptops are not included on a list of affected machines that was issued last July by HP, so they are ineligible for a free repair or an extended warranty.

One laptop model with overheating problems is the Pavilion dv9500 line, with screens going blank or overheating, leading to system failure, customers wrote on one HP board. The laptop model isn't on HP's list of affected laptops, and in some cases HP is asking users to pay for repairs.

HP isn't moving quickly to add new laptops to the list of affected PCs, customers wrote. Users are asking HP to examine and update the list of laptops affected by the issue. Laptop failure may also result from components unrelated to the issue with graphics cards, but a trend among posted complaints points to laptops with Nvidia parts, said Matthew Hilsenrad, an HP laptop owner.

"I hadn't seen any post of ATI chips going bad, only Nvidia chips going bad," Hilsenrad said. "A whole lot of people [on the boards] who bought the laptop around the same time seem to have the same problem."

Hilsenrad owns a Pavilion dv9500 model with a Nvidia GeForce 8600 series graphics card, which he bought in September 2007. Many laptops not included in the list - including the HP Pavilion dv9500 and dv9600 series - bought in 2007 are now experiencing similar problems, Hilsenrad said.

He was asked to pay around $400 to replace a motherboard when overheating rendered his laptop screen dysfunctional. He called HP to request a fix, but the PC didn't fall under the extended warranty that HP issued for affected laptops.

After haggling with an HP case manager, he got the laptop repaired for around $215. However, the case manager said the affected laptop list could be updated to include the model he owned, in which case he would be refunded the amount.

Another poster, Salman Fateh, reported system failure and a blank screen on an HP Pavilion dv9500 with a Nvidia 8600 series graphic chip, which was purchased in October 2007.

"HP will not honour the extended warranty for this model. HP should honor customers and replace all laptops with defective Nvidia GPUs," Fateh wrote in a separate HP forum.

Customers echoed Fateh's opinion, saying that unless HP addresses the issue quickly, their laptops would become paperweights.

"HP needs to add the rest of these bad GPU units on the list, get them all repaired," wrote a poster with the screen name Sarah Locker on HP's board. "I don't want to blame HP for Nvidia's manufacturing fault, but it appears now that HP is the one that is dragging their feet."

HP didn't immediately comment on this story. Officials from Nvidia were not available to comment either.

Nvidia last July said that some of its graphics chips were overheating due to packaging material and the thermal design of some laptops. HP subsequently issued an advisory warning of possible laptop failure and a list of models affected by the Nvidia parts.

HP also issued a BIOS patch to keep system fans running longer to prevent overheating, and offered to repair laptops depending on certain symptoms. The affected laptops included some HP Pavilion dv2000, dv6000, dv9000 models and Compaq Presario V3000 and V6000 series laptops. HP also offered a 24-month warranty extension to affected customers in North America.

Other PC vendors, including Dell and Apple, had to address issues related to faulty Nvidia graphics cards. Like HP, Dell issued a software patch to control heating problems, but it attracted a fierce response from unhappy users, who accused Dell of shying away from addressing a larger problem of bad hardware. Apple offered a free repair of laptops with faulty Nvidia graphics cards.

New Bluetooth 3.0 devices to hit market later this year ‘09

The Bluetooth Special Interest Group (SIG) has recently announced the new Bluetooth 3.0 standard to boost wireless data transfer between devices to 24Mbps from the recent data transfer rate of just 3Mbps for Bluetooth 2.1 standards. In fact, the Bluetooth 3.0 specification is an update from the Bluetooth 2.1 protocol, which was adopted by the group in 2007. bluetooth-3.0-logo

A standards group has approved specifications for a new Bluetooth standard that speeds up wireless data transfers between devices like smart phones and laptops. Bluetooth is commonly used to pair mobile phones with wireless headsets for hands-free talking. It is also used to connect a mobile phone to a laptop to synchronize data or transfer multimedia files without using wires. Over 2 billion devices have shipped with Bluetooth built in, according to Bluetooth SIG report.

The adoption of the standard, and devices based on the Bluetooth 3.0 specification could ship later this year ‘09 or by early next year ‘10 near the holiday season. However, post specification adoption might delay the products on the market. The faster data transfers could lead to its adoption in a number consumer electronics devices beyond just mobile phones.

The Bluetooth SIG has expected Bluetooth 3.0 to make its way into PCs, mobile phones, camcorders, cameras, TVs, digital presenters - devices that consumers use to transfer large data files like those of video, photographs and even entire music libraries.

The standard enables faster data transfers while using less power, giving consumers improved responsiveness and better battery life in mobile devices. It also stabilizes connections between devices, ironing out kinks from earlier standards when connections broke after a device like a cell phone was placed in the pocket. The Bluetooth 3.0 radio is based on Wi-Fi standards, which enables better data throughput while delivers power-saving benefits for mobile devices. It uses short bursts of Wi-Fi to send data, after which the radio is shut off until it is needed again.

DSLR Battle Heats Up: Nikon Launches New D5000

Nikon Europe announced the introduction of its latest DSLR, the D5000. The D5000 has inherited the D90’s groundbreaking HD movie capability, Nikon’s proprietary D-Movie function (the D90 was the first DSLR to sport video recording). The 12.3MP sensor has sensitivity between ISO 200 and 3200 (can be extended to ISO 100 and ISO 6400 equivalent). The feature being touted is the 2.7-inch vari-angle LCD that allows you to take pictures easily from any angle. When combined with live-view (the ability to see the frame on the LCD screen) it 1gives a high degree of flexibility in composing shots with off-beat perspectives and macros.

The display can be closed to protect the monitor or place it in the standard position for regular shooting using the viewfinder. You can even reverse the monitor for effortless, perfectly-framed self-portraits. A 4 fps continuous shooting mode makes it a fast camera and it can shoot 67 JPEGs or 11 RAW files continuously.

Nikon has retained the 720p movie mode from the D70 but the rival’s 500D goes all out with full HD 1080p video recording. When taking still shots, the camera offers four types of contrast AF (wide area, normal area, face detection and new subject tracking) to make capture as easy as possible. In subject tracking AF mode, the camera will even restart tracking the subject once it leaves the frame and then returns, so your target will always be in focus.

With a total of 19 scene modes, the 5000D is more newbie friendly. To quote the press release, ‘simply turn the dial to ‘scene’, choose the appropriate scene mode setting and the camera will do the rest for you. The camera will even display a sample scene to make the scene selection easier for you’. Sensor cleaning is implemented with airflow control system (Canon uses vibration to get rid of dust on the sensor).

The press release did not specify the list price, but websites reported a price tag of $849 (approx. Rs. 42,450) for the D5000 with the 18-55mm VR kit lens. The Canon 500D has a list price of $899 along with the 18-55mm IS kit lens.

Yahoo, Google Set Up Web Sites For Election in India

Google and Yahoo have launched special sites dedicated to coverage of the General elections starting April 16 in a bid to build their brands among Internet users in the country.
The interest of the companies signals the growing importance of the role of the Internet in Indian elections. A number of Indian political parties are using Web sites, e-mail and videos on YouTube to reach voters.

Google, for example, estimates that 25 million of India's 45 million Internet users are of voting age and are actively looking online for information on the elections and other issues.
The Internet has emerged as an important medium for people to interact and debate with other voters, political parties and candidates, said Gopal Krishna, Yahoo's vice president for emerging markets and acting country head for Yahoo India, on Tuesday.

An estimated 100 million new, young voters will be qualified to participate in this election, and many of them are likely to be Internet users, Krishna added.
Last week, Yahoo set up a micro-site, Election '09 (http://in.elections.yahoo.com/), which offers election news coverage, schedules, online polls and discussion forums.

A tool on the site, called "Your Manifesto," also allows users to select issues of importance that let politicians know what interests them. "This feature will be of tremendous value for political parties, because it provides an insight into what is going on in the voters' minds," Krishna said.

Google launched on Monday an online elections center (www.google.co.in/loksabha2009) in both English and Hindi. The company has partnered with a large media company, Hindustan Times Media, to offer a co-branded site.

Update your geek knowledge, Video Editing terminology

This post contains terminologies and their definitions related to Video Editing in a Computer. For details, you are suggested to google them. The definitions are adapted from Nero 9. If you are looking for Disc Burning terminology, visit this post.

AVCHD
The Advanced Video High Definition is a new file format for HD captures on DVD, memory
card or hard drive. Especially new camera modules use high-resolution formats that capture
AVCHD in various variants (e.g. 1920x1080i or 1080p). The video material is compressed
with the MPEG-4 AVC/H.264 codec. Audio is saved in AC3 (Adaptive Transform Coder 3)
format or for the standard NTSC and PAL formats in Linear PCM format.

Bit rate
Bit rate refers to the amount of data (binary digits) that is transmitted within a time unit (generally
1 second), i.e. in bits/s. The higher the bit rate, the better the image quality.


Blu-ray
Blu-ray technology refers to burning on special data carriers. In comparison to DVD's, which
use a red laser in order to read and write data, Blu-ray discs are written with a blue laser.
The shorter wavelength (405 nm) of this blue laser makes it possible to position the laser
with greater accuracy. Data can be written in a more compact manner and takes up less
space on the disc. A Blu-ray disc can store up to 25 GB on a single layer disc and up to 50
GB on a dual layer disc.


Book Type
The book type defines the specification (e.g. DVD-, DVD+, DVD-ROM) of a DVD. In order to
ensure correct playback, the DVD specifications are defined in books so that all media can
be read correctly. The specifications are defined in the so-called Rainbow Books, which are
distinguished by means of their color (e.g. Yellow Book).


Capturing
The capturing depicts the transmission of, e.g. audio or video data in their original quality on
the computer. Here the data can then be further edited.

Digital TV Card
With a digital TV card, digitally transmitted content can be received. Digital TV signals are
compared to analog signals by their higher quality,


Disc format
Disc format defines the the format in which the data is organized on a disc. For example, the
disc format DVD-VR is only supported by and can only be used with DVD-RW and DVDRAM
discs. For example, Video CD (VCD), Super Video CD (SVCD), miniDVD and (if supGlossary
ported) HD-BURN can be burned to CD-R and CD-RW disc formats. The technical options
available, such as subtitle or multiple sound tracks, are a factor of the disc format.


Disc type
Disc type refers to different optical storage media with different specifications. The best
known are CD's and DVD's that can be written to once or multiple times, and which are manufactured
with different storage capacities.


Dual
The Dolby Digital compression procedure is a multi-channel sound system that is used on
DVDs, in cinemas.and on TV. It supports bit rates of 32 kbits/s to 448 kbits/s and permits a
high grade sound reproduction over up to 6 channels.


Dual tuner card
If you wish to simultaneously see a TV channel and wish to capture another one, then a second
tuner must be integrated in the TV card.


DVD+VR
The DVD+Video format recording (video mode) is a particular variant of the DVD-Video offering
three possibilities missing on DVD-Video: 1) On-the-fly capture of videos on the disc in
real time is possible. 2)The data on the disc can later be edited and altered. 3) More video
titles can be added if space is still available on the disc. This means that a DVD+VR is similar
to a video cassette, but of a far superior quality. Once the disc has been finalized, the
DVD+VFR format is essentially compatible with DVD-Video and can be played in most DVD
players. The storage capacity doubles for burning to a DVD+R DL disc as does the space for
the DVD+VR.


DVD-VFR
The DVD-Video format recording (video mode) is a particular variant of the DVD-Video offering
three possibilities missing on DVD-Video: 1) On-the-fly capture of videos on the disc in
real time is possible. 2) the data on the disc can subsequently be edited and changed. 3)
More video titles can be added if space is still available on the disc. This means that a DVDVFR
(video mode) is similar to a video cassette, but of a far superior quality. DVD-VFR (video
mode) allows you to create menus like DVD-Video, although without chapter menus and
playlists. A DVD-VFR is compatible with DVD-Video as far as possible after finalizing the
disc and can be played back on most DVD players.


DVD-Video
The DVD-Video disc format uses the MPEG-2 video codec for compressing video files onto
a DVD. This compression allows a 4.38 GB DVD-R/-RW/+R/+RW to hold up to 135 minutes
of video with significantly higher quality than that achieved with a VHS video or with a video
CD. The disc can be played on most DVD players, which means, for example, that you can
store home videos with very high quality. Computer DVD drives with appropriate software
can also play DVD-Video. A DVD-DL disc (DL = double layer) doubles the storage capacity
of a disc and, as a result, the space for a DVD-Video.


DVD-VR
The DVD video recording is a particular variant of the format of the DVD-Video, which offers
three possibilities that are missing on the DVD-Video: 1) the direct capturing of videos on the
disc is possible in real-time. 2) The data on the disc can subsequently be edited and changed.
3) If there is place still available on the disc, then further video titles can be added. This
means that a DVD-VR is similar to a video cassette, but of a far superior quality. The DVDVR
is specifically designed for capturing directly to disc. A graphics menu is not supported,
but playlists are created instead. Furthermore, the sound track cannot be changed, i.e. it is
not possible to edit or add to the existing track. DVD-VR is not compatible with DVD-Video
and can only be played on special DVD players.


FireWire
FireWire is an interface for the transfer of data at high speed; it was developed for hardware
such as camcorders or hard drives. The serial high-speed bus allows for transfers of 100 to
400 Mbit/s in the so-called IEEE 1394a or FireWire 400 standard and up to 3.20 Mbit/s in the
so-called IEEE 1394b or FireWire 800 standard.


Frame Rate
The frame rate denotes the number of pictures, which are shown per second. The unit is fps
(frames per second). The higher the relationship the more fluid the movements become.


Hybrid tuner card
A hybrid tuner card provides the possibility of receiving TV signals digital terrestrially as well
as analog via cable.


LPCM
The Linear Pulse Code Modulation permits the loss-free capture of digitally coded analog
signals. This technology makes possible the saving of up to 8 channels in different sampling
rates and sampling depths on a single DVD.


MPEG-1
The Moving Picture Experts Group defined this industry standard for video and audio codecs.
MPEG-1 is part of the MPEG compression family and has the highest compression rate.
MPEG-1 is the format for video CDs.


MPEG-2
The Moving Picture Experts Group defined this industry standard for video and audio codecs.
There is little difference between MPEG-1 and MPEG-2: MPEG-2 is a broadcast standard
and better for televisions that are interlaced. MPEG-2 is used as a video format for
DVDs.


MPEG-4
The Moving Picture Experts Group defined this industry standard for video and audio codecs.
MPEG-4 is the latest MPEG standard for video and audio. MPEG-4 combines several
functions from MPEG-1, MPEG-2 and other standards. Nero Digital™ Video and Nero Digital
™ Audio are based on this standard.


Nero Digital
Various MPEG-4 video and audio codecs are collated in Nero Digital and are fully compatible
with the standard MPEG-4. Nero AG is continuing to develop these. In this way a substantially
higher quality of the multi-media data is achieved. Further, additional features such
as subtitles have been implemented.

NTSC
The national television system Committee Standard is a standard for video and TV in the
USA and Japan. NTSC has more individual frames (29.97 frames per second) than PAL, but
has fewer horizontal lines (525 lines).


PAL
The Phase Alternation Line procedure is the TV standard applicable for Europe. PAL possesses
625 lines per screen and the film transmission speed is 25 pictures per second. These
are transmitted in the so-called line-jump procedure where a picture with all the odd lines
and then a picture with all the even lines are created. This corresponds to a half-picture frequency
of 50 Hz.


SmartEncoding
SmartEncoding checks whether your contents are compatible with the respective formats or
are coded into the respective format. This saves time so that coding of the formats can be
dispensed with. The file is not converted only "packed differently". Thus, the contents maintain
their original quality.


Super resolution
The interpolation with super resolution algorithms permits an increase of resolution in picture
and video material. Thus, for instance, old DVDs can be converted to HD material. The increase
in resolution is the result, among others of information on previous and following pictures.


TWAIN
TWAIN is a standard for the exchange of data between a picture input device such as a
scanner and a software for purposes of further editing.


VBR
Material encoded with a variable bit rate (variable data rate) generally provides a better quality
in contrast to normal saving of audio or video files with a fixed bit rate (CBR, Constant Bit
Rate). With a variable data rate individual time sections can be coded with differently customized
data rates. Movement area scenes in videos are stored with a higher data rate than
stationary pictures. Strongly moving scenes thus require more storage space that can be saved
with less mobile scenes.


VCD
The Video Compact Disc saves movies and audio/video data in MPEG-1 format. In doing so,
the video quality from a VCD is similar to a VHS video. VCDs can store up to 74 minutes of
video material including stereo sound on a 650 MB disc. Most optical PC drives and DVD
players can play VCDs.


WMV
The Windows Media Video format is a video codec from Microsoft. The coding is comparable
with the MPG-4 format. The copy DRM (Digital Rights Management) protection is also supported
by the WMV format.

Windows XP Support Ends Today

Microsoft will drop Windows XP out of mainstream support today, with the ageing OS moving into extended support as previously announced.

Microsoft's mainstream support, which is usually offered for only five years, actually ran for seven-and-a-half years because of Windows Vista's long delay. Two years ago, Microsoft also extended mainstream support for XP Home and XP Media Center until 2009, and the deadline for the follow-up phase, dubbed 'extended support', until 2014, to match the dates that had been set earlier for the business-grade XP Professional.

According to Microsoft, the transition from mainstream to extended support for Windows XP means that it will only provide paid support - on a per-incident basis, or through its various pre-paid support programmes - and will only offer non-security hotfixes for a fee, and then only to customers who have purchased the Extended Hotfix Support plan.

Microsoft will continue to generate free security updates for Windows XP, and release them via Windows Update, until April 8, 2014.

Windows XP's shift into the first phase of support retirement comes at a time when the operating system remains extraordinarily popular, especially among business users. According to a recent survey by Dimensional Research, 97 percent of the more than 1,100 IT professionals surveyed said that their companies and organisations are still running XP.

The move out of mainstream and into extended support also comes just days after a leaked Microsoft memorandum spelled out a relaxation of the rules for computer makers that want to continue selling new PCs with the aged OS.

OEMs will be allowed to advertise new systems as XP PCs, something that hasn't been allowed since June 2008, and can 'downgrade' a licence for Windows 7 - the operating system that hasn't yet been released - to XP for at least six months after the former's launch.

A Microsoft spokeswoman said that support for XP on a new machine is provided by the computer maker, not Microsoft. "Customers who purchased Windows XP pre-installed on their machines will receive support from their Original Equipment Manufacturer (OEM) per the OEM support policy at time of purchase," she said.

Google Improves Gmail on G1 and iPhone

Google has announced it has improved access to its Gmail webmail service from mobile phones running its Android operating system and Apple's iPhone.

Key to the updated Gmail, accessible through the browsers on iPhones and the Android G1 phone, are changes that let people use the service even while their mobile connections are flaky or unavailable, Joanne McKinley, a Google mobile engineer said in a blog. Users will be able to open recently read messages and compose new mails even when out of range of wireless service.

"All this is achieved with aggressive caching and by leveraging new browser technologies, like HTML5 and Gears. The full impact of this new architecture isn't visible yet, but it will enable us to significantly improve performance and quickly roll out new features in the near future," she said.

Such developments could make browser-based mobile applications more common, a trend that could help solve the fragmentation issues that are slowing down application development in the mobile environment.

According to Christy Wyatt, vice president of software platforms and ecosystems for Motorola, the web "could be a universal access platform" for mobile applications. Wyatt said developers currently need to rebuild their applications to work on the various platforms if they want a wide potential audience. The web could serve as an open development platform for applications accessible from any web-enabled phone so that developers don't have to rewrite their apps.

While there are shortcomings to building web-based applications for mobile phones - namely that mobile networks aren't always reliable and developers can't leverage all mobile phone capabilities in apps - the executives said those are not insurmountable problems.

Adobe's runtime environment provides offline capabilities so even when applications are web-based they can run offline, said Danny Winokur, senior director at Adobe.

Eventually, essentially any application that now requires software on the device will be able to be run from the web, said Sumit Agarwal, head of mobile product management for Google.

"What apps can you say can't use the browser? Before, you didn't have access to location [from the browser], now you do," he said. "Maybe soon we'll have access to the camera and the speaker. It's not clear to me what aspect of the device you won't have access to in the browser."

Winokur agreed. While there currently may be performance issues, extension capabilities within runtime environments let developers plumb many of the capabilities of the device up to the runtime layer, he said.

The Gmail update should also make the application work faster when users do things like open a message, navigate and search, McKinley said. It also includes a couple of other changes such as a 'floaty bar' that stays on the screen as users scroll through messages and that contains options to archive and delete messages.

Apple to Increase iPhone Storage, Says Report

Apple has ordered large amounts of Flash memory to be used in a new iPhone expected in June, according to reports. What makes this report interesting is that Apple is allegedly ordering twice as much Flash as it did last year, according to reports from DigiTimes. A large request for Flash from Apple backs the rumor of a larger capacity iPhone model, slated for early this summer.

The DigiTimes report continues claiming Apple ordered 100 million 1GB NAND Flash chips, mainly from Samsung Electronics. Apple could recombine these chips in the manufacturing process, creating 16GB and 32GB (Gigabyte) storing capabilities for new iPhone models. One hundred million 8Gb chips would be enough for 12.5 million 8GB iPhones or around 3 million 32GB devices.

Speculation around Apple's massive Flash memory order could mean that the long-rumored 32GB iPhone might be on its way and possibly a larger capacity 64GB iPod Touch. In the case of the iPod Touch, 64GB could mean a much higher price, somewhere around $500. A 32GB iPhone is feasible, especially as video-recording capabilities are expected in the new model (requiring more storage).

However, Apple uses this kind of NAND Flash chips in other of its products as well, like the iPod nano and Shuffle, so at the moment it is not very clear how the Cupertino company will use the 100 million chips. As previously reported, the new iPhone model is expected to feature a better camera (with video recording) and higher storage capacities, besides the 3.0 software improvements announced last month.

Update your geek knowledge, Disc Burning terminology

Bridge Disc
A Bridge Disc is a variant of a CD-ROM that can be read from CD drives but also from CD-I devices such as a Photo CD for example. It is defined in the White Book Standard and contains extra information in an XA (Standard Architecture) track on the CD-ROM.

FAT
FAT (File Allocation Table) is a file system developed by Microsoft. The FAT 12, FAT 16 and FAT 32 file systems are used on all types of mobile storage media (e.g. USB sticks, memory
cards).

ISO 9660
The International Organization for Standardization defined the Universal Standard 9660 which determines the features of the CD. This format is platform-independent and can thus be read by computers with different operating systems. In order to ensure universal readability, the file names used should be as short as possible. (In a DOS environment no more than eight characters may be used).

Joliet
Joliet refers to an extension of the ISO-9660 standard for file names. Joliet was designed by Microsoft in order to represent more characters. The file name can be up to 64 characters long and contain the letters A-Z, a-z, umlauts and the ß.

Multisession Disc
A multisession disc can contain several sessions that are not fixed. This way, more data can be added in new sessions at a later point in time, and the disc is not closed until it is full.

NTFS
New Technology File System is a Windows file system. Its advantages include differentiated access and rights management, as well as defragmented data storage, which allows the processing speed to remain high.

Packet-writing
Packet-writing refers to a procedure for writing to optical media incrementally. An optical medium, e.g. a DVD, can be used as a hard drive as a result. This way, files can be copied, moved, changed, or erased on the respective optical medium.

UDF
The Universal Disc Format is a platform-independent file system. File names can be up to 255 characters long; 8 and 16 bit character sets are supported.
