What is Windows 8????

Windows 8 is so conceptually and paradigmatically different from its predecessors that it’s actually quite hard to mentally grasp. Is it a desktop OS, tablet OS… or both? What about phones; it runs on ARM tablets, so what about ARM smartphones? Will it eventually replace Windows Phone 7? Windows 8 really is a re-imagining of what Windows is, and something of a rebirth for Microsoft, so you would be forgiven for not knowing the answers to these questions. There’s a slew of really cool features that have been drowned out by the introduction of Metro — security improvements, power consumption tweaks, cloud integration… and more!

Read on, and we’ll do our best to explain exactly what Windows 8 is, and more importantly what it isn’t.

• Windows 8 will not run equally well on ARM and x86
  Yes, Windows 8 will run on both ARM (Snapdragon, OMAP) and x86 (Intel, AMD) processors, but the experience will be very different. 
• The Windows 8 Metro, tile-based interface is designed specifically for low-power tablets, and touch-enabled computers
  Despite Microsoft’s reassurances that the new, tiled Start screen will feel at home on keyboard- and mouse-driven computers, the entire interface was designed from the ground up to be a tablet- and touch-first interface.
• Windows 8 will be the most secure Microsoft OS ever
  In Windows 8, Windows Defender — the anti-spyware service that is installed by default on all Windows 7 machines — is being bumped up to a full anti-virus/anti-malware suite, and in fact it looks almost identical to Microsoft Security Essentials.
  The move away from BIOS towards UEFI — Unified Extensible Firmware Interface — means that Windows 8 also provides anti-malware protection at boot time: if you try to boot while an infected USB memory stick is plugged in, Windows 8 will warn you and refuse to load.
• Windows 8 will boot in just a few secondsThe combination of UEFI and some other slipstreaming to the boot process means that Windows 8 will cold boot in just a few seconds. This is fairly inconsequential, though, as Microsoft wants you tohibernate Windows 8 rather than shut it down; especially if you’re on a tablet where instant-on is a necessity.
• Windows 8 will have built-in “Factory” Reset and Refresh
  In an another delightful twist, Windows 8 will have two features that will amaze and delight everyone: Reset and Refresh. Reset restores Windows 8 to its base, just-like-new state. Refresh is similar, but it preserves all of your documents.
• 
• Windows 8 (or at least the Server version) will feature Windows To Go, a bootable “live CD”
  In Windows 8, you’ll be able to plug in a blank USB stick and simply push a few buttons to turn it into a bootable Windows 8 installation.
  
  
• Windows 8 Metro will be powered by Internet Explorer 10
  The Metro interface is powered by the Trident rendering engine and Chakra JavaScript engine from Internet Explorer 10. The runtime stack has also been rejigged so that full, “native” apps can be written in HTML and JavaScript. 
• 
  
• Windows 8 will feature the Windows Store, which is just like the iOS or Mac App Store
  Metro apps are all secured by a sandbox with severely restricted functionality — and that makes them perfectly suited to a safe-for-all-the-family, moderated-by-Microsoft Windows Store.

Electricity Generation From Human Breathing – University of Wisconsin

Developers have always been in search of alternative ways for the generation of electricity. Some of them have been the use of piezoelectric crystals that generate electricity from body movements, biological fuel cells which have the ability to produce electricity from blood sugar level of a person, and wireless transmission of power from outside the body. A new method has now been developed to produce electricity from a person’s breathing rate.

This device is manufactured by the University of Wisconsin, and it relies on piezoelectric effect, but contrary to relying on body movements to produce mechanical stress, this device makes use of speed of air flow that is a reason of a person’s respiration rate to cause vibration of the plastic micro belt engineering inside the device. This belt is made up to polyvinylidene fluoride (PVDF).

India launches cheapest TABLET

India launched what it dubbed the world's cheapest tablet computer Wednesday, to be sold to students at the subsidized price of $35 and later in shops for about $60.

Most of India's 1.2 billion people are poor and products such as Apple Inc's iPad are beyond the reach even of many in the fast-growing middle class.

Below are the main features of Aakash:

• It runs on Android 2.2 (Froyo)
• 366MHz Connexant CPU with Graphics accelerator and HD Video processor
• 7-inch resistive touchscreen with 800×480 resolution
• It has got 2 USB ports, has 256MB of RAM and 32GB internal memory, expandable via microSD
• It has 2100mAh battery which can reportedly last for 2-3 hours
• It comes with a 12-month replacement warranty
• It comes with a standard 3.5mm headphone jack.
• For connectivity to internet, it has got a 802.11 a/b/g WiFi chip and a GPRS modem
• It supports formats like DOC, DOCX, PDF and PPTX etc.
• Supported audio formats: MP3, AAC, AC3, WAV, WMA
• Supported video formats: MPEG2, MPEG4, AVI, FLV
• It weighs 350 grams
• Price – $35 (Rs 1800) with govt. subsidies; $60 (Rs 2900) commercially in stores

With Steve Jobs' passing, we have lost one of the greatest technological innovators of our time.

Jobs wasn't just a savvy businessman, he was a visionary who made it his mission to humanize personal computing, rewriting the rules of user experience design, hardware design and software design. His actions reverberated across industry lines: He shook up the music business, dragged the wireless carriers into the boxing ring, changed the way software and hardware are sold and forever altered the language of computer interfaces. Along the way, he built Apple up into one of the most valuable corporations in the world.

Quite a run. He will be missed.
