Imagine yourself around the turn of the century- sometime around 1999-2002. Internet is evolving, Java is hot, XML is roaring and more and more people are joining the formative Internet Atlantic.

Big Data is the new buzzword; a name given to the enormous amount of data that is piling up over time at an unprecedented rate- and that rate is increasing explosively.
As a CS freshman I was required to present on an emerging technology of my choice. I chose Big Data Processing Using Hadoop, with the focus being on general understanding of the core rather than technical depth. So here is a four part general write up: Part 1 covers the very fundamentals of Big Data and Google’s milestone contribution towards its processing. Part 2 discusses the development of Hadoop- an open source approach for the processing of Big Data.
Words are wonderful. They have a long life. Even centuries cannot fade their charm. From leather, cave walls, leaves, all the way to papyrus and the modern day paper, words are loved, cherished, admired and awed- they play wonders. Time stands still- such is the power and beauty of words. You can see them, touch them and get touched by them- on paper, on your iPhones, your iPads and many other devices.
The year 2014 is about to witness the explosion of an amazingly disruptive technology - Bluetooth Smart and it’s manifestation as iBeacon from Apple. It is essentially a micro location technology and in iOS it simply extends its location services. It can alert apps (in your mobile devices), when you are in the proximity of a location which has a Bluetooth Smart transmitter. You only need an iOS7 or later on your device, Bluetooth turned ON and a compatible device such as iPhone 4S, iPod (5th generation), iPad mini or an iPad (3rd generation).
Sick of carrying too many of your plastic money, aka credit cards, with you? Well, help is in sight. PulseWallet have demonstrated their amazing plastic free, wallet free, secure, always available,hands only Point-of-Sale solution at the gadget show, CES 2014 in Las Vegas, NV. It is a simple yet highly attractive innovation in the domain of identity- a really sensitive territory with all the stealing going around. Fear no more, you do not need to carry your cards.
Our airways are guarded- 24⁄7! This interesting finding has been reported in the March issue of the American Journal of Respiratory Cell and Molecular Biology in the paper titled “Volatile-Sensing Functions for Pulmonary Neuroendocrine Cells”. According to this finding, there are olfactory receptors located in the membranes of Neuroendocrine Cells in our lungs. These lung receptors when activated, say, by acrid smoke or some pungent odor, trigger the release of airways constricting hormones by the PNECs (Pulmonary Neuroendocrine Cells).
Intel announced Edison, a processor for wearables at CES 2014. CEO Brian Krzanich introduced this 22nm technology, dual core, Quark SoC based processor capable of running Linux and other Operating Systems, with built-in Wi-Fi and Bluetooth connectivity. It supports Wolfram Alpha and have its own dedicated Edison-Centric App Store! Intel demoed the potentials of this “Pentium-Class PC in the form factor of an SD Card” through some interesting applications. The more interesting ones were a pair of battery less, energy harvesting earbuds that track biometrics while playing audio, a charging bowl that charges wearables dropped in them (such as the smart earbuds) and a clip-on smart baby monitor that can be linked to an Edison powered bottle warmer that warms and readies itself whenever the monitor sends the signal that the baby is hungry as suggested by her movements.
Fresh, clean, sweet water is a blessing. Life depends upon it. In the developing world many lose their lives because of its scarcity. Access to clean water for the masses in the developing world is, therefore, a great challenge. To take up this issue Gabriele Diamanti has come up with his Eliodomestico, a solar household still. It is an “open project free to the people who need it”. The hall mark of this still is its simplicity - no electricity, no filters zero environmental impact and very easy maintenance.
