 kernel panic - not syncing : VFS : Unable to mount root fs on unknown-block(0,0)
CPU: 1 PID : 1 Comm: swapper/0 not tainted 4.4.0-164-generic #192-Ubuntu
Hardware name : Apple Inc. MacbookPro5.5/Mac-F2268ACB , BIOS MBP55.88Z.00AC.B03.0906151708 06/15/09

Call Trace :
dump_stack*0x63/0x82
panic+0xd3/ 

Solved by hard shutdown , again started and got into the GNU GRUB menu - the screen with the prompt == grub> 
This was the wrong place to be - thus == grub> normal ... and yes now back to the GRUB MENU.
#
Here  2 Kernels listed - 1/  4.4.0-164-generic , with (upstart) and (recovery mode),     2/ 4.4.0-31-generic , with (upstart) and (recovery mode)

Went ahead and chose -
4.4.0-31-generic , did not use a live disc or usb to boot back in , as of now all systems - Go !! lets see what else is required ...

DARK DATA --- Structured / Unstructured {CONFUSION}

According to SPLUNK - "Dark data is all the unknown and untapped data across your organization, generated by systems, devices and interactions. Dark data can be any kind of data. It can be a log file from a website, server, network or application."

 

So all dark data is unstructured data, but not all unstructured data is dark data.

WHY ??? So ... arent Website Logs Structured DATA ??

"Augmented Analytics Is the Future of Data and Analytics” Source -  Gartner

So what exactly is - "Augmented Analytics " , lets explore :-

    Augmented analytics: This technology includes ML-enabled analytics and BI in all phases of the analytics workflow, from data preparation to data modeling and insight generation.

Megavendors and startups alike continue to execute on their augmented analytics roadmaps, but at different paces and with differing degrees of sophistication and innovation.

For example, augmented alerting and anomaly detection are new trends in augmented analytics, with only a few smaller vendors offering these at present.

Although augmented analytics is not yet attracting mainstream buying activity, it remains a transformative differentiator that commands higher prices (see “Augmented Analytics Is the Future of Data and Analytics”). In addition, customers who were early to adopt visual-based discovery now face a proliferation of data and user-created analyses. As they mature their analytics, these customers are anxious to embrace this next wave of disruption.

Further, customers who were late to modernize their traditional BI platforms are asking if they can simply skip ahead to augmented analytics. SOURCE -- GARTNER
