Musing on Big Data example. Not an easy recipe to follow

If a picture is worth a thousand words, as the beaten adage goes, the use of big data, creative analytics and graphics is certainly worth much more. Here is a great example of using Big Bata to explain migration from The Economist.

As with most pictures, what is depicted here is only a small slice of the big frame, the angle the author/analyst wanted to highlight. 
I like this picture for the story that it is trying to tell different audiences in a visually appealing way. A picture like this is sure to resonate with policy makers, corporate executives and even hiring managers and recruiters. If not anything else, it raises questions and follow-up actions from the information depicted.
 
The recipe for big data analytics might look like this:
  • Define your analysis goals and audience upfront
  • Take a lot of data from different sources
  • Filter the data and replicate, but remove redundancies
  • Add relevant metadata, tags etc
  • Use relevant indexing to navigate the data environment
  • Run a lot of filters and queries on it
  • Present actionable information
  • Turn the information into insights
As is obvious, the recipe or its variances for data analytics are not easy to follow. For one, there is a challenge of defining a problem statement. And then there is the science of gathering data, developing the engine to run the analytics. Then comes the art of visualization while presenting the information.

As one might argue, there is a secret sauce missing in the recipe above!

Nobel Peace prize for 2014 and musing on David and Goliath

It is heartening to see the Nobel Peace prize for 2014 go to two South Asians, Indian children’s rights activist Kailash Satyarthi and Malala Yousafzai, a Pakistani teenager shot by the Taliban after campaigning for girls’ education.

I’ll admit, like most others living in the west would do, that Malala Yousafzai is a well known name but Kailash Satyarthi, who? I am sure this is about to  change with the announcement since most of us will not only become aware of Mr Satyarthi but also about the cause for which he stands.
Having just finished reading Malcolm Gladwell’s bestseller (my #amzaonreview), I was reflecting on Malala Yousafzai and her branding as the unlikely role of David she has been thrust upon to go against the Goliaths (Taliban) in Middle East and South Asia.

If I build on Gladwell’s argument in defense of “underdogs” who become unlikely heroes, Malala would certainly be on top of the list. Ever since Malala was shot by Taliban while on her way to school, her recovery has been watched, analyzed and projected larger-than life by western media. As per a recent Chicago tribune article, (link
"Yousafzai was only 11 when she began anonymously blogging for the BBC about her struggles. She was 14 when Taliban gunmen boarded her school bus, asked for her by name, and shot her in the head and neck. The girl survived and was flown to the U.K. for treatment."   And the rest, as they say, is history in the making
One can argue that in the fight against the bad guys, the Goliaths and Taliban, one has to win over the hearts of the public. A teenage girl, part of the underdog strata in the society that still oppresses women, who goes against the bad bully, Taliban is just the kind of hero one needs to win the hearts and minds of junta (public).  And by awarding a Nobel Peace prize to the teenage hero, we are doing just that: reinforce the will of Davids’ to stand up to the Goliaths!

Hewlett-Packard and slices of pizza!

It is interesting to read the announcement on the split of yet another tech giant, Hewlett-Packard, coming shortly after the breakup of eBay and Paypal. Every time I read announcements on mergers and de-mergers, the image of a large pizza with different toppings on each slice comes to mind.


(Image link)

It is also interesting to note the spin with announcement of mergers and demergers.  When companies, producing different products or services merge, announcements highlight “synergies” in the “value enhancing move.”  And when a company like - Hewlett-Packard announces a demerger, it is yet another value- enhancing move that allows us to “invest in the respective asset groups without the fear of cross- subsidies and inefficiencies” (link)
 
The impact on people, employees and stakeholders including customers, who are left to manage the change - management speak for those left catching the falling knife – from such de-mergers, has been studied ad infinitum. And so has the impact on the groups of people who benefit from mergers and demergers: shareholders and investors, lawyers and consultants.
 
The footnote in the analysis of Hewlett-Packard’s Value enhancing move Planned job cuts will increase to 55,000 and costs to restructure cost will be about $600 million.” made me wonder: $600 million to slice a corporate pizza?!

Selfie generation unable to sit back and smell the roses?‏

While stepping out of the supermarket the other day, I was pleasantly surprised to see a double rainbow. Not very common; but also not something we see every day.
 
 
After standing still, watching the rainbow for a few minutes, I looked around: a mother and her teenage son quickly got their cellphone to “capture” the moment. So did another man who was walking up to his parked car. And so did a dad with an amused toddler. The only two people in the parking lot not “capturing the moment” in their cellphones were the toddler, who didn’t have one, and me standing amused by others’ selfie moment. 
 
The ease with which modern cellphones enable capturing pictures and videos also means that almost every moment of our lives are now worth capturing digitally, leaving little or no incentive to really enjoy the moment.
 
By capturing the moments digitally we hope to share them with others connected by social media. Since all of our friends and peers share “unique” moments of their lives, we don’t have an urge to resist digitally capturing a few moments.
 
Thankfully, our five year old doesn’t have a cellphone, and is content to enjoy the occasional double rainbow, spotting a deer or rabbit in a park and even just stopping to smell the roses (literally) while taking a walk in the park.
 
Note to self: resist the urge to capture these moments in my smartphone.

Book Review. David and Goliath: Underdogs, Misfits, and the Art of Battling Giants

My #bookreview of "David and Goliath: Underdogs, Misfits, and the Art of Battling Giants" on #Amazon.com

Every now and then comes a book that holds a mirror to us and the society we live in. David and Goliath, is one such book with perspectives that are sure to stick in mind for a while.

The book starts with an analysis of how the underdog shepherd David really beat the giant Goliath. The story of Vivek Ranadive's team of underdog "little blond girls" from silicon valley who beat the giants in basketball to end up in Nationals is heartwarming. With Caroline Sacks' story, Gladwell highlights "relative deprivation" and the blessing of being a big fish in a small pond versus the other way around. The next chapter focuses on Dyslexia's blessing in disguise. At least for the lucky few who are able to nurture other talents like a photographic memory.

In the last section, the author builds a contrast between the stories of Mike Reynolds and Derksens which makes one reflect on the "limits of power." The contrast in the attitudes, especially at times of crisis really hit home for me. Although Gladwell paints shades of black and white while describing attitudes of Mike Reynolds and Derksens, in reality most of us end up philosophizing like Derksens with shades of gray in our minds. The author builds on this contrast with the story of Andre Trocme, just to emphasize the point!

Gladwell skillfully holds together myriad stories with his beautiful narrative and storytelling abilities.

WSJ: A Mole Inside Assad's Embassy. Double Agent or Traitor?

The article by Adam Entous in Wall Street journal made for an interesting read, but to me raised more questions on the Author’s intent. (WSJ Article “A Mole Inside Assad's Embassy Aided Syrian Rebels”)

The Article’s tone was that of projecting Mr. Bassam Barabandi a diplomat of the Syrian government in the US as a “hero” for betraying his government and also misusing his authority. The article begins by describing.
In his embassy post over the course of a year, Mr. Barabandi issued travel documents for nearly 100 Syrian activists, according to interviews with him and more than a dozen opposition leaders. Through his efforts, activists were able to flee and campaign against the same regime he officially represented.
Based on the analysis of how the diplomat issued travel documents to hundreds of “Syrian activists,” the author Mr. Entous begins to project Mr. Barabandi as a modern day robin-hood. The angle conveniently omitted by Mr. Entous in his story.
  • What if the passports issued by Barabandi went to members of the ISIS/ISIL or the other bad guys? Without any due diligence, how did Mr. Barabandi ascertain the credentials of Syrian activists?
  • The article hows it is “easy” for a rogue diplomat to issue/re-issue passports of a sovereign nation. If it were this easy to hack the system, could a rogue American diplomat in Russia re-issue travel documents for Mr. Edward Snowden? (my earlier blog post on Snowden saga)
The last paragraph in the article gives away the true intent of the WSJ article’s author:
Mr. Barabandi and his wife have been interviewed by U.S. officials reviewing their application for asylum. They now are waiting to hear a decision. If the U.S. says no, Mr. Barabandi said, maybe he will try Canada.
Those of us who have jumped through visa and immigration hoops in our lifetime will immediately realize the author’s real intent: a positive cover story in WSJ added to Mr. Barabandi US asylum application dossier is sure to grease the wheels at the USCIS!
Giving Mr. Barabandi the benefit of doubt; most of the recipients of his passport scam may be good guys, but if his act happened to also benefit a few bad guys, the effort would be in vain!

Frequent flier Miles and points: how far will they take you?

I haven’t blogged in a while. The reasons are several including procrastination during summer vacation. I hope to continue with the blog, now that I am back and refreshed.
 
This summer, I planned a family trip (with my wife and son) from Anytown, US to Bangalore where my parents live. While planning the trip back in Spring of 2014, I decided to explore the possibility of burning some of my accumulated airmiles.

I am not a miles junkie at least not as much as I used to be. This said, I will gladly take the small, perhaps the only, perk of business travel that comes in the form of air mile credits and hotel loyalty points.
 
I shall refrain from naming the carrier where I had accumulated nearly a million miles and now have a measly ‘silver-elite status (but here is a hint this airline traces its roots to the illustrious Pan Am). Not long ago, when I was a ‘road warrior’ IT consultant , it was much easier to earn a lot more air miles, and more importantly acquire and retain privileged Platinum “Elite” status with the airline. The biggest benefit of an elite status, besides the ability to change flights without additional fee was that I frequently got bumped up to first-class while traveling in the US – lots of leg space without the need to worry about knee defenders.
 
Of course, it is much harder to maintain such coveted status with the airline, now that I don’t travel as much; and the few cross Atlantic business trips a year don’t really cut it with them! I spent a couple of days searching options on the airline’s website with the following constraints:
  • I had to be able to book three returns tickets from Anytown, US to an airport closest to Bangalore where the airline flies
  • Ensure that the major leg of our trip could be on business class
Turns out most US carriers don’t fly directly to Bangalore. A few fly into Mumbai or Delhi. And Airlines are less generous with miles on code-share flights with partner airlines, and especially less generous with those who don’t have higher elite tiers (like I said earlier, that is a perk that makes being a road-warrior worth it).


After a few days search, I zeroed in on two options: fly from Anytown, US to Mumbai or to Dubai and book an additional return flight from DXB/BOM to BLR. The difference was the return trip to DXB would burn about 140,000 miles (per seat) versus 180,000 to Mumbai. I decided on the former and decided to extend the trip with stopover for a day-long tour of Dubai.
 
The trip was great, with minimal disruptions. A few lessons from this experience
  • Be flexible on airports and itinerary. As I mentioned above, we were flexible in planning a trip with a stopover in DXB instead of BOM.
  • Change fee is expensive, but may be worth paying. I booked the trip in spring and didn’t have much of the vacation planned. Work and other scheduling came in the way after booking the trip which meant I had to cough up a change fee for the itinerary. Bottomline: change fee of $150 on a cross-continent trip using miles? Worth it!
  • Free is not always free. Even free tickets issued using airmiles are taxed. One has to pay the airport tax and other fees that can add up to a tidy sum for cross-continental flights.  There are other costs and incidentals one needs to plan for, especially if you don’t have a higher elite status with the airline in question. Costs like change fee, standby fee etc can add up.
  • Be prepared for “Attitude” from (some) of the ground crew. An example: on the return leg, while getting our boarding cards, I asked the lady at the checkout counter where the business class lounge in DXB was. She gave me a ‘look’ and asked if I were eligible to enter a longue on a ticket issued with points. I had to stand my ground and insist on this simple prevlidge (DXB airport requires US airlines’ staff to endorse tickets for longue access as most don’t have their own longues)
Bottomline: The effort expended in being able to burn accumulated airmiles for a family vacation is totally worth it!
