Red Shift vs. Azure SQL Data Warehouse

In recent times both Amazon.com and Microsoft have made bundles of cash with their cloud assets. Amazon had the advantage of being the first to get into action (2 years earlier) with Red Shift. In the Data Warehouse scenario Microsoft’s Azure SQL Data Warehouse and Red Shift are clear competitors.

Now Scott Guthrie has challenged Amazon's Red Shift (http://aws.amazon.com/redshift/). According to Scott, Azure allows you to make adjustments to compute in just seconds that is beyond the capability of Red Shift.

The other Azure capabilities are,
• can pause/resume a cluster
• can be turned 0ff so you only pay for storage
• can be deployed and run from on premises

ConnectTheDots.io project provides a jumping board to Microsoft Azure IoT

Event Hubs, Stream Analytics, Azure HDInsight and Machine Learning are the components of Microsoft's way of doing IoT. However these 'words' may be little too much for those who want to toy with IoT and somewhat intimidating.

With ConnectTheDots.io, an open source project initiated by Microsoft Open Tech a playground is available to get started with Microsoft Azure Services  IoT projects. Makers, IoT geeks, systems engineers and enterprise developers can all participate. The cloud is the brain.

ConnectTheDots.io provides simple, step-by-step procedure to connect your device to Microsoft Azure via RaspberryPi and Arduino Interfaces. The next example is from SLAC at Stanford University where a huge amount of data is being sent to Azure Cloud for Analysis. This 'Proof of Principle' should encourage all National Laboratories to come on board with their control rooms replaced by simple, multiple connected handhelds.



Microsoft has demonstrated the hooking up the Microsoft wand (device) to Microsoft Azure. Read here:

Read more here:
https://msopentech.com/blog/2015/04/06/connectthedots-update1/
http://microsoft-news.com/tag/connectthedots-io/

The project has boiler plate codes to connect devices to Azure services mentioned earlier and help coming up with a website to show the response from the devices. Of course data-analysis is an integral part of the project.

The project is expected to grow as more sensors/devices are developed

WinJS 4.0 is in preview. Get it now!

WinJS is a cross-platform JavaScript library for building HTML5/CSS/JavaScript applications across devices. When it was announced first in 2014 it was Open Sourced. The version in preview is 4.0.

The feature set got beefed up with the following: (http://visualstudiomagazine.com/articles/2015/04/01/winjs-4-preview.aspx):
  • Universal experiences: UI controls will scale or translate among various devices without having to go through significant rewrites.
  • Addition of controls: ContentDialog, SplitView, AutoSuggestBox and ToolBar controls are now available; Hub and Pivot controls and other controls are updated.
  • AngularJS Support: An AngularJS-WinJS wrapper allows WinJS-originated code to be used in AngularJS projects.
  • ListView Improvements: "ListView is a signature control for WinJS," according to the Windows blog. As such, its capabilities have been streamlined to work almost identically from mouse- to touch-enable device: multi-selection, lists in alternating stripes, progressive loading of elements in a list, to name a few.
You can (WinJS4.0 and full feature list) download from here ().

There is also an online playground here:

Would you pledge $50 to buy UDOO Neo?

Looks like an ideal hardware to have in your collection and used for developing IoT projects.

UDOO (sounds like voodoo) Neo seems to hold best of all stuff for IoT development. UDOO is in the Kickstarter stage and you could be an early well-wisher.
Their email shows that it has all of the following:
• Raspberry PI
• Arduino
• Wi-Fi
• BT 4.0
And Oh! Sensors.
Looks like they garnered $15k in under 11 minutes.
Coming to realities, it is credit-card sized, low-cost, low-power guzzler and Open source and can run both Android and Linux &&& Arduino-compatible.

It can be used 3 ways:

• As a Full-fledged computer
• As an Arduino compatible micro-controller
• As an embedded computer -IoT

It comes in flavors, UDOO Neo Basic and UDOO Neo with very little pledge range.
Even the features of the basic unit are attractive:
• 512 MB Ram
• One USDB Port
• One Micro-USB OTG Port
• HDMI Video Output  for LVDS
• Wi-Fi module
• Bluetooth 4.0  module
• Analog & Digital camera connection
• 54 GPIOs
• Micro SD card for OS
In addition to all of the above, the UDOO Neo also has fast Ethernet and 9-axis motion sensors embedded with 1GB RAM instead of 512 MB.
If all of this are present, I think I would pledge.
For specific details go the originators at these sites:

Google's Project Fi takes off

This has been in the works for long and now it is ready. Are you paying for set bulk rate for data from the likes of AT&T and Verizon? Well it worked but not for those who want to pay for what they use. Project Fi does it for you what AT&T and Verizon do not. It will even reimburse for data not used.

Right now you ask to be invited to join the program but later it is for all who wants it. The free software model starting with Android was a huge success and as Android is a global market leader for smart phones it will be easy to get them on to Project Fi.

The seamless transition from cellular to Wi-Fi is a very attractive feature, a feature that all smart phone manufacturers should emulate.

OSISoft PI System; Microsoft Azure Fabric & Microservices

Microsoft is releasing in the near future Azure Service Fabric as a preview beta (http://azure.microsoft.com/blog/2015/04/20/announcing-azure-service-fabric-reducing-complexity-in-a-hyper-scale-world/).


Azure Service Fabric is built to run microservices - a complex application consisting of smaller, interlocked components that enables updating components without disrupting service. Microsoft has used this over the past few years internally for many of its own applications and the new release is for general use, a new product.

http://azure.microsoft.com/blog/2015/04/20/announcing-azure-service-fabric-reducing-complexity-in-a-hyper-scale-world/

OSIsoft is an early adopter of this system and run with it to expand into the exploding IoT market.
OSISoft's PI:

PI is a system envisaged to bring sensor data directly to the board room minus the human middle man. This is one embodiment of IoT to not only get the data but analyze so as to provide deeper insight and provide operational intelligence.

Here is OSIsoft overview (from OSIsoft site),

"OSIsoft, a global leader in operational intelligence, delivers an open enterprise infrastructure to connect sensor-based data, operations and people to enable real-time and actionable insights.--"

Moving towards IoT: 5G challenges and trends

5G is not just faster data and/or higher capacity only. It is much more than these obvious characteristics.

For one thing for IoT to succeed; the grand vision created for its debut on a universal scale, 5G is a must. More users; more devices interconnected at any instant of time. The 5G must address the issues arising out of interconnected devices in addition to only users. Also for IoT to succeed additional items like coverage of the serviced region (Can you hear me now!) and more efficient networks.
The data rates required by 5G are some 1000 times that provided by 4G to make things happen with low latency. One immediate challenge is the unavailability of spectrum (700 MHZ to 3 GHZ). Two options open to work on are,
• Explore new spectrum
• Innovate usage of existing spectrum to send out more bits
Explosive growth of connected devices both arising out of human interaction as well as from embedded devices. The connected devices are heterogeneous in nature with low as well as high bandwidth which can presents significant design challenge to work in unison. This impacts deterministic response time and must be well understood to realize the full potential.
Moving towards 5G
• Overcoming the limitation of orthogonal frequency-division multiplexing - exploratory generalized orthogonal frequency-division multiplexing (GOFDM) as demonstrated by University of Dresden, Germany providing 30% more data rate than 4G designed by using National Instruments RF tools and LabView.  -Reference: http://www.eetimes.com/document.asp?doc_id=1266564
• Increasing the number of access points (densification)- Use of Multiple input, multiple output(MIMO) base stations' promise of increased efficiency and better energy efficiency - Lund University MIMO experiments demonstrate date rates some  100 times
 -Reference: http://www.hermes-europe.net/home/univ-lund-realized-mimo-testbed/
• Using wavelength region not heavily populated like the 28GHZ, 38GHZ and the 71 to 76 GHZ range - usability demonstrated by NYU Wireless and Nokia has prototypes a mmWave communication link achieving some 100 times 4G rates.
-Reference: http://nyuwireless.com/research/

It may not just one of these will pave towards 5G but a combination of these and yet to be made new developments will ultimately steer 5G towards the future.

This post was motivated after reading the PDF document from National Instruments (NI) and draws heavily from its content. The added references are for those who may want to read more.

A gun mounted camera as an IoT device

It will be interesting (perhaps quite easy) to develop a tamper-proof Gun mounted camera which can automatically log all activities and stream load data to a Cloud Service. Such a device should be a standard official issue. In fact as gun related violence has been on the radar, it should be mandatory for all registered guns.
