Latest Read: Flash Boys

Flash Boys: A Wall Street Revolt by Michael Lewis is a remarkable Wall Street story. Lewis lays out a series of interwoven stories that result in flaws around High Frequency Trading (HFT). While not the subject of a SEC investigation, the book’s publication has resulted in fines for companies trading in less-than-honest environments.

Flash Boys begins with the story of Sergey Aleynikov. Sergey is a talented programmer who is key to this story. We meet him as he faces prosecution.

The early chapters involve cutting fiber optic cable runs via Spread Networks from Chicago to New Jersey, This was most appealing to me. There was an understanding that trades could be altered in measurements of just milliseconds. 4 milliseconds is the timeframe trading companies needed in order to gain an advantage against their trading competitors. 4 milliseconds!

Enter the ability for large corporate banking firms to trade within their own dark pools. The practice of front running was taken to a new level with millisecond transfers. It adds up to shifts in profits away from smaller traders to benefit Wall Street banks.

The idea of milliseconds sounded strange at first. It is impressive to learn how trading firms and large banks were pouring money into advanced networks. Yet this resulted in the 2010 Flash Crash. Most could not understand how computers could cause the market to crash. It was just the beginning of questionable trading practices.

Latest read: The Wealth of Networks

I have been looking at The Wealth of Networks: How Social Production Transforms Markets and Freedom as a learning tool for social networks impacting society and found this a very deep read….like a college econ/sociology textbook.  Caught myself thinking I was actually back in school. This goes much deeper than Groundswell: Winning in a World Transformed by Social Technologies.

Harvard law professor Yochai Benkler has written a very comprehensive book to describe conflicts between analog and digital data creators in society and how internet based technologies are changing society and commerce.

It’s a good read but hard to grasp due to a focus on economics. Don’t be fooled the by title if your looking at computer networks….he has written it into the binding that ties his arguments together.  It is truly worth the read.

Benkler shares how technology has merged the professional and the consumer into a ‘prosumer’ due to low cost and high performing computers and robust networks have made distribution of information cheap enough that community is now empowered to drive change.

Take a look at how the internet has evolved.  The Akami to YouTube migration showed how multimedia has found a free, reliable distribution center.  When you also migrate 1st generation complex, large scale websites to new blogs and content management systems under the open source business model Benkler states that data is now a “non-rival” product that has democratized the digital workflow of data from brick and mortar to community, peer-developed content solutions.

Benkler suggests modern computing drives new, strong and deep collaboration that can have a large impact on the global economy and society.  Benkler also suggests that as more consumers embrace technology collaboration, change to our culture is possible due to engines of free exchange (wikipedia, creative commons, open source and the blogosphere) could be more efficient (when shared) than current models that are restricted by copyright and patents because the ability to duplicate (or reproduce digital content) makes little or no impact on business.

Google’s Learning Management System

Google has released their internal learning platform, CloudCourse under an open source license. Built entirely on Google’s own App Engine, CloudCourse is a new entry into a crowded LMS arena.  CloudCourse provides calendaring, waitlist management and approval features.

To no surprise CloudCourse is fully integrated with Google Calendar.  Google has also made CloudCourse customizable for schools by supporting service provider interfaces:

Sync services – Sync CloudCourse data with school’s internal systems
Room services – Schedule classes in school locations
User info services – Support for school profiles (employee title, picture, etc)

CloudCourse was built in Python and uses Django (web application framework) and the Closure Javascript library.

OLPC XO-3: third time’s the charm?

With much lower fan fare OLPC has released it’s latest attempt to bring a educational computer to the world’s children.  The OLPC project has had a series of hits and misses.  The initial release known as the XO-1 was received as a minor success.  The expectations could not be higher — bring advanced computing to the world’s poorest students.

one-laptop-per-childThere is much advanced technologies in these devices.  The target goal is under $100 for the 3rd generation device which is projected to ship in 2012.

OLPC received much attention since its launch with the UN, but the release of the XO-2 was scene as a break through that never materialized.  With tough economic conditions and globalized part manufacturing I’m not sure OLPC will be able to ship a tablet device by 2012 but boy I would sure want them to succeed.

I believe OLPC and its supporting research groups have made a huge impact in the computing world.  Before OLPC there were no netbooks….Negroponte‘s vision has already created a new marketplace.

The one real miss was the Sugar OS.  Sugar was designed for children yet due to the marketplace and influence of Microsoft, OLPC has adopted Windows as a supported OS.  I will never be convinced that children need to learn Microsoft Windows in order to use a child-friendly learning device.
