Hey Guyz, This is the Amazon Kindle Fire HD claimed to be the most advanced tablet.

7.6" x 5.4" x 0.4" (193 mm x 137 mm x 10.3 mm). It weighs about 13.9 ounces.

The display is a 7" and 1200x800 display with polarizing filter and anti-glare technology. It supports video playback at 720p. That is the same resolution with which i am working on with my laptop's 15" 4' screen.(THAT'S HUMILIATION)

The tablet sports a 1.2 Ghz dual core processor with Imagination PowerVR 3D graphics core for fast and fluid performance. It has a 1GB RAM - double that of 2011 model. It is available in 16GB and 32GB internal memory model.

It supports a 3.5mm audio jack and Dolby Digital Plus to give you crystal clear sound. It features dual-drive stereo speakers.

  • USB 2.0 to connect to PC and connect chargers.
  • Micro HDMI port for high definition video output
Ambient light sensor, gyroscope ,accelerometer

It's arguably the fastest WIFI with dual band, dual antenna WIFI with over 40% speeds. It is capable of automatically switching between 2.5 Ghz and 5 Ghz frequencies.

Over 11 hours of reading, surfing the web on WIFI, watching video or listening to music as claimed by Amazon.

Under 4 hours with Kindle PowerFast charging accessory and slightly longer with micro USB power adapter.

The feature list seams pretty impressive and no doubts the tablet is quite advanced in its technology. The only thing i found not so impressive is that it only supports a 1.0 Megapixel front facing camera and no rear facing camera. But the overall feature list would definitely speak loud in favor of this tablet.

Due to my exams, i have not been able to update my TechTuned. But here's some news about the Apples new addition to the i-family. iPhone 5 has broken all sale records.

Apple received over 2 million advance bookings for iPhone 5 within the first 24 hours of pre-orders double the number of pre-bookings it received for iPhone 4. It is the fastest selling iPhone the company has ever offered. Apples initial stocks finished within a few hours.

The craze for the device is reflected by the fact that even when the date for availability for the device in retail stores is 21st September, people are lining up in front of company stores. Apple's store on Regent Street in London saw buyers camping in advance to buy the device.

According to TOI, Apple is approximated to sell 10 million units of iPhone 5 in September itself. Samsung Galaxy S III took about 2 months to achieve the same milestone

I'll cover full feature list of iPhone 5 as i get free from exams on 21st September, the same day iPhone 5 becomes available in stores.

Till then, STAY TUNED.

I recently started programming in OpenGL so i decided to post an update on the latest version of OpenGL released by Khronos group on August 6th, 2012.

The latest version is OpenGL 4.3. The new feature list includes:
  • compute shaders that harness GPU parallelism for advanced computation such as image, volume, and geometry processing within the context of the graphics pipeline;
  • shader storage buffer objects that enable vertex, tessellation, geometry, fragment and compute shaders to read and write large amounts of data and pass significant data between shader stages;
  • texture parameter queries to discover actual supported texture parameter limits on the current platform;
  • high quality ETC2 / EAC texture compression as a standard feature, eliminating the need for a different set of textures for each platform;
  • debug capability to receive debugging messages during application development;
  • texture views for interpreting textures in many different ways without duplicating the texture data itself;
  • indirect multi-draw that enables the GPU to compute and store parameters for multiple draw commands in a buffer object and re-use those parameters with one draw command, particularly efficient for rendering many objects with low triangle counts;
  • increased memory security that guarantees that an application cannot read or write outside its own buffers into another application’s data;
  • a multi-application robustness extension that ensures that an application that causes a GPU reset will not affect any other running applications.
This post is not only to update you readers about OpenGL but to renew interest in fellow programmers about the API. The growing DirectX influence in the 3D graphics market and Microsoft's massive marketing campaign has resulted in a mighty blow to OpenGL's popularity. I have no hate against DirectX but OpenGL in no way is inferior to DirectX. Both API's have their own capabilities and applications and no one can underestimate the capabilities of any one.

So, All my programmer readers, Try OpenGL and stay TUNED.
