Since the Big-Bang of the cyber world, internet becoming public during 90′s, the cyber universe expanding with increasing growth rate. The infographic by JESS3 agency visualizes the status of the current social networks and points to the emergence of new social platforms such as friendster, badoo, besides the well known titans such as Facebook, Skype, Twitter.

Especially, if we compare the data to the 2010 version of the info-graphic, very interesting points show up:

• We see that Skype with 663 million users, is ahead of Facebook in the registered user count. That is an important rationale behind Microsoft’s acquisition of Skype. However, we have to note that Facebook with more than 500 million active users, is still ahead vs Skype with about 180 million active users in terms of active usage. In this regards, we can still clearly say, that Facebook is the biggest active social network.
• In webmail networks, we see Hotmail leading followed by Yahoo and Gmail.
• Myspace appears to have passed the point of no return. With a steady decline, it’s gonna be hard for the company for sale to find a new buyer.
• Twitter is growing rapidly.
• The “made in china” version of Facebook, Qzone, is soon to reach its original.
• Some mobile device oriented location based services networks are still the smaller links of the socio-cyber universe, but Google Latitude and Foursquare show some remarkable growth.
• The mobile device market is continuing the exponential growth, the increase is in billion levels

Facebook has always been in the spot light somehow since its kick-off and it never stops to amaze us with its growth rate.  From 2004 til 2011 the company increased its headcount approx. 50% every year and has about 2000 employees as of today.

However, the impact factor of Facebook is not the its own economy, but rather the eco-system it created around itself. In this regards, since one of the most strategic movements of the company, to open the Facebook API to 3rd party developers in 2009, the job listings including the Facebook keyword increased 245% according to SimplyHired reports. These listings involve mostly non-engineering positions, as well as engineering positions, including a variety of domains such as application development, data analysis, marketing and PR.

If we analyze the numbers, we see an incredible growth and even more important an increasing growth rate. Today, there are more than 550 000 active Facebook applications. Considering it took only 4 years to reach that count, this is pretty huge. However, it is even more striking how much added value these application bring. Even if only Zynga is considered, which is a social gaming company significantly fueled by Facebook, its value is estimated to be around 7 billion $. Another example is Facebook fueled social match making company Snap Interactive, which doubles the 2009 revenues and lists 6.7 million $s revenues in 2010. Quite remarkable!

As it seems, while Twitter is still trying to figure out a profitable business model, Facebook is already in a very different page.

Air transportation has always been a domain of interesting and complex problems in terms of operation management. It involves numerous uncertainties from planning to implementation, while requiring long resource planing and scheduling horizon.

While you can buy a ticket conveniently with couple clicks, there is an incredible e-commerce infrastructure with parallel processing capability (simultaneous ticketing for a spot from numerous agencies), fleet management (harmonization of airplanes for the highest efficiency) and numerous other logistics solutions such as crew management and airport/gate/check-in planning in the back-end. Further uncertainty is induced by the break down/maintenance and unexpected delays.

The situation is similar for the capacity planning and pricing of such a complex system. The flexible ticketing options emerged by the demands of the customers induce further uncertainties. In the world of production and service systems, uncertainties have a significant consequence: MORE COST. More costs reflect as higher prices to the consumers. Simply put, the extra capacity needed because of the uncertainties is compensated by the customer – in the lack of competition-.

In this case, competition is an important catalyst for the airlines to develop new ways to cope with  and compensate the uncertainties as the profit margins are shrinking (such as overbooking). An article in New York Times illustrates how extra we are actually paying and how significant the impact of competition is.

Hidden city ticketing

If the figure is analyzed, tickets to hub-cities dominated by a carrier, where the competition is weak, are extremely expensive. In fact so expensive, that if a connecting flight is added to a destination city with a more competitive market, the prices go down. For example Fargo – Chicago flight costs $528, whereas Fargo – Chicago – New York flight costs $213. Unbelievable isn’t it?

In conclusion, if you buy a ticket for Fargo – Chicago – New York and don’t take the connection flight, you can get the half price for Fargo – Chicago ticket. This situation is not apparent in Turkish Airlines domestic pricing, but for international flights, where the market is much more competitive, this is a viable strategy to consider. At the same time this type of inconsistencies, which seem irrational for the customer obviously affect the trust and loyalty of the customer.

Just like many of you, I didn’t hear the news that Osama Bin Laden was killed from a TV channel, nor a news agency, nor an official institution, but Tweets bursting out from Twitter, Facebook/MSN IM networks, simply put from friends in a  ”on the grapevine” fashion and within a time frame of about 3 hours after the first public source.

We are observing the evolution of journalism. Actually, I realize that I haven’t read a paper published newspaper for so long that I’m missing the joy of a journey between the pages of a newspaper on a sunday morning.

Lets check the numbers first… According to Twitter’s official announcement, tweets about Laden’s death broke the Sustained Tweet Rate record and reached 3000 tweets per second over 10:45pm – 2:20am period. After USA president Obama’s speech it tweet rates reached 5008 tweets per second. This rate can reach the average daily visits of New York Times online (~30million) in about 3 hours. The exponential spread and later the damping of the tweet rate can be noticed by the tsunami like shape in the figure. This quantitative growth raises qualitative concerns, as it is commonly seen that false news go viral on twitter, but 3000 tweets per second is a significant rate.

If we approach this emerging trend from the consumer behavior perspective, we consume “news” much like other goods, there are many analogies. After the industrial revolution, the era of mass production emerged, profit by mass production & sales of a single product. When Ford manufactured his first cars, the consumers didn’t used to have too many options, just like everybody used to read the same newspapers and watch the same tv channels in the early years of the media.

As the technical improvements evolved, and new production methods emerged, there was a paradigm shift in late 90′s to mass customization. To be honest, we are extremely spoiled. If we think of today’s extreme, you can buy your iPhone/iPad with the configuration you want and with your name laser-written on the back (Henry Ford would probably drown in tears, if he would experience this).

This nature of ours is apparent in all types of consumption. We want to have our own choices. When we read news, we want to compile our own configuration with the authors we prefer, fuse the knowledge we want to synthesize through RSS channels, and consume it through the interface we prefer.  Products for mass audiences simply don’t make the cut. Especially if news is considered, the time lag of conventional methods results in old news once it reaches to the customers. When establishing our corporate and personal identities, we cannot neglect these changes.

The digital world is by-passing the intermediaries and makes us come one more step closer to the source of everything, while a new era is shaping in front of our eyes.

Recently an interesting incidence happened in E-Commerce giant Amazon.

As reported by Michael Eisen, 17 copies of the biology book “The Making of a Fly” by Peter Lawrence published in 1992 (not printed anymore) was for sale on Amazon. 15 second hand copies started from $35.54, whereas 2 new copies were sold starting from exactly 1730045.91$.

More interestingly, the two sellers of the new copies have both profiles with high customer satisfaction feedback and high transaction volumes and they both ask for more than million $s . This abnormal situation lead to a much more interesting discovery. Eisen followed the behavior of the prices, both rising steadily and discovered a very simple relationship between the two sellers prices.

Profnath, strategically was positioning itself “slightly” below the market price to be price competitive and draw more customers to its e-store, so it was setting its price exactly 0.9983 times the lowest market price. Bordeebook, on the other hand, was relying on its high sales volume and excellent customer feedback to increase its profit margin, thus setting the price to exactly 1.270589 times the lowest price. As there are no other new copies of the book, these sellers run into an infinite loop, where they rise the prices to the roof (million $ level). Furthermore, this kind of responsive behavior raises the concerns, that Bordeebook maybe does not even posses the actual copy of the book and acts as a reseller.

Today, while firms essentially consider the production and market data for pricing, it is not possible to overlook the competitors data and strategy. Especially, e-commerce enables possible ways of automation and leads to new, emerging situations. The main reason for these kind situations is that it is impossible to manually maintain such a diverse inventory of enormous volume. Therefore, as in the case of Amazon doing business with countless suppliers, for the sustainability of the system automation is inevitable. Thus, interesting price tags with .01$ precision are mostly outputs of smartly prepared scripts. In this regards, process control is obviously necessary, as I doubt someone would be interested in a regular book sold for million $s.

Facebook hosted an online, live townhall meeting with USA president Obama in Palo Alto headquarters. This event was very important for both Facebook and Obama. From the day he was elected, presidents poll results indicated decline. For the re-election campaign the utilization of Facebook platform is a significant move as it features over 155 million users in USA with 62% under the age 35. Even people in my network who devotedly supported “Obama for Change” campaign are far from the excitement in 2008.

Although it was not covered in the video published, Zuckenberg greeted the USA president Obama, referring to 19 million followers on his Facebook page, “Welcome home president”. The opening speech of the president explains the rationale of this meeting very well:

The main reason we wanted to do this is, first of all, because more and more people, especially young people, are getting their information through different media.  And obviously what all of you have built together is helping to revolutionize how people get information, how they process information, how they’re connecting with each other.

And historically, part of what makes for a healthy democracy, what is good politics, is when you’ve got citizens who are informed, who are engaged.  And what Facebookallows us to do is make sure this isn’t just a one-way conversation; makes sure that not only am I speaking to you but you’re also speaking back and we’re in a conversation, were in a dialogue.

And really Obama continued with a warm tone to address questions ranging from economy to immigration, education, health care, partly picked from the web, partly from the Facebook employees among the crowd.

From Facebook’s perspective, the largest social network did the first move hosting this dialogue to bridge the internet with the world of politics, definitely adding to its brand value. Different than the conventional media, Facebook audience interacted over the web and become a contributor of this town-hall. Thinking of internet as a factor democratizing the world (literally), social networks such as Facebook, abstracting and virtualizing our identity promise a great potential. Just to give an idea, think of virtualizing elections or referendums, where people can very efficiently represent themselves with an e-government social network infrastructure.

This is a new era. Just like the corporate firms are one step closer to their customers with the social media, the politicians are reaching their voters through Facebook, Twitter, Youtube much faster. As a leader very well connected to the social media, we will see if Obama can prevail again in the 2012 elections adding new “friends”.

Since I came to realize that I exist (?!), music was an important way of my self expression.

And our journey with kep starting from 2001 with the roots up to 1999 -when I picked up the bass guitar-, has been an important part of my life.

kep @ itu

It was my privilege to play bass in a trio of very talented musicians, my high school friend Kemal Tolun (vocals and guitars) and my cousin Koray Ozsoy (drums).

I would define kep as a band full of energy and fun (definitely characterized by the sound of “Kaset”), of course compensated by my sour influence (as in “Yalnizlik Turkusu”).

I always loved to define our sound as the sound of Beyoglu (a unique place at the heart of Istanbul, bringing all the diversity together). It ranged from alternative rock to funk-rock heavily influenced by Turkish tunes and rhythms.

Especially in the early years, it was a significant experience for me as a song writer and a bass player with a funky taste to experiment on compositions and our tunes. In the following years, as we started to make our way to the main stage, it was a semi-pro stage experience, where we got to realize many others enjoying what we are doing. This encountering was the main motivation that kept us going. We played for bar gigs without a count, numerous festivals and events. On our way we’ve met with very important friends, our nameless heroes, but cannot pass without naming Ramazan Toktay, who engineered our sound and helped to manage this act.

This is an open letter to thank everyone involved, listening, hosting, sharing and making this a unique experience.

Thanks!

As we parted ways to discover different paths of life, kep is conveniently resting for a while… catching breath, preparing for new chapters. new stories..

This statement of purpose is intended to be a brief reasoning and vision for my web / blog.

First of all it is a selfish act, where I basically try to organize my observations, thoughts, creative process and put it all together in a documentary. The aim is to be -hopefully- more productive and efficient.

Secondly it is a collaborative act, where I try to reach out to those, who are interested in the content, have their own experience & skill set, and are willing to collaborate create new synergies. Let it be anything I cover here (projects, music etc ) or even completely new stuff.

Finally, I try to showcase an auto-biography: who I am, what I do, what life means to me and what my outlook is.

I am looking for participation and involvement to breed seeds of synergy and higher aspirations.

This is my vision for the journey.

Set sail! Rastgele!

New design, new beginnings…

Action!

Globalhawk UAV

Nowadays, nothing is simple. We are dealing with convoluted problems, which require convoluted solutions.

Working on an Unmanned Aerial Vehicle (UAV) project as a project engineer, I have experienced numerous times, how important the systems engineering aspect is.

The engineering approach to complete such a huge specific project requires detailed work division and allocation to specialists in granular level. However, it is not possible to think of these sub groups as individual modules. Any design specification in one of these modules, is also important for other modules as it has impact on the functionality of others.

For instance considering such a multi-disciplinary project, aero-design, electro-mechanical design, electrical system design and digital system design are all coupled.

How? The fuselage and control surfaces impose design specifications on electro-mechanical design, which imposes design specifications on the electrical system design and digital system design is affected by all of the systems and vice versa. Sometimes the relationship is hierarchical, whereas some times it can be unilateral. So how to approach the problem with the systems perspective?

First it’s important to understand, what we mean by systems:

“A system can be defined as a set of elements standing in interrelations” (von Bertalanffy 1968).

Sperwer UAV

A UAV system involves many components, such as aerodynamic design (fuselage, control surfaces, etc), payloads (surveillance systems – gimbals, etc), electrical system (bus powering other systems ), electro-mechanical systems (to mechanically control the motion, payloads etc) and digital systems (auto-pilot, measurement systems etc).

Also, the system as a whole is a part of a system of higher level. The UAV should be inter-operable to be controlled by base stations via the protocols standardized by organizations such as NATO.

The most important thing in the systems perspective is the integration of development phasing, life cycle integration with the systems engineering management. This involves the definition of baselines in the development phasing, integrated teaming and life cycle planning for life cycle integration.

Let it be a complicated engineering project such as this one, or an industrial project involving  the design of a distribution network, the system engineering design process considers the system as a whole, instead of individual modules.

The design process of the system between process inputs and outputs is very closely coupled.

Is systems perspective vital? Can we survive without this closely coupled integration?

Probably yes, but we would require countless re-design, re-work and countless deadline extensions…
