    re not big fans of what I consider vertical ambition that is the usual career path trajectory in which a newbie moves up the ladder from associate to manager to vice president over a number of years of service On the other hand we revere horizontal ambition in which employees who love what they do are encouraged to dig deeper expand their knowledge and become better at it We always try to hire people who yearn to be master craftspeople that is designers who want to be great designers not managers of designers developers who want to master the art of programming not management via inc com At Vinova we are doing the same by building a skillful passionate and inter dependent team Team members wear many hats and work in harmony toward a common goal Each member should be the boss of his own More May 21 2011 You Need to Win the Battle for Share of Mind by solving a real problem The challenge that many startups face today is Are you really providing enough value Will you get the TechCrunch bump the tier 1 VC anointment followed by great PR firm support and then the NY Times or WSJ story that follows Will that be enough or will high churn rates creep in new toys be introduced into the market new time sucks pulling user attention away This year s Tamagotchi If you re building a startup today I would encourage you to think harder about how you re going to win the battle for share of mind That s much tougher than getting people to play with your hot product for 6 months To do so you must truly provide value that changes the way that end consumers do something in their lives that will persist via bothsidesofthetable com More May 21 2011 Silicon Valley Guru Steve Blank Welcomes The New Bubble And Says Microsoft Is Doomed The LinkedIn IPO absolutely marks the beginning of a bubble and he thinks it s going to be great He likens it to the Netscape IPO in August 1995 that kicked off four years of boom times but notes that this time VCs actually know how to build real companies with real revenue and profit Crazy investors not geeks are what makes Silicon Valley unique Without the crazy financiers willing to take big risks in hopes of chasing obscene returns the valley would just be a bunch of smart scientists and entrepreneurs sitting in their labs and their garages Microsoft will start to fail within six quarters Blank put a timeline on Microsoft suffering the kind of huge loss that drove IBM to restructure itself back in 1993 six quarters from now He thinks Steve Ballmer is a miserable failure and that the board should be blamed for not replacing him He also suggests that buying Nokia and installing Stephen Elop as CEO might be a solution But Larry Page is doing the right thing at Google By letting

    bank in Singapore invest millions of dollars create a computing and predicting system from scratch using Haskell a static type functional programming language to warranty scaling and performance I wonder why the bank did not take a look at Distributed File System DFS MapReduce Hadoop is an open source implementation of it as a massively scalable on commodity hardware that successfully utilized at biggest IT firms in the world Google Yahoo Facebook just to name the few or they just re implementing DFS MapReduce themselves More February 22 2010 What is Hadoop from Interview with Amr Awadallah Cloudera CTO First it s worth making the important clarifying point that Hadoop is not a database Hadoop is a data processing system and in fact I would even go as far as saying Hadoop is an operating system The core of an operating system boils down to a file system the storage of files and a process scheduling system that runs applications on top of these files There are many other components that help with devices credentials and user access and so on but that is the core Hadoop is exactly the same thing The core of Hadoop is the Hadoop Distributed File System which is a file system that s runs across many nodes It links together the file systems on many local nodes to make them into one big file system Hadoop MapReduce is really the job scheduling system that takes care of scheduling jobs on top of all those nodes That is the key distinction between Hadoop s approach and that of database systems Hadoop at its heart does not require any structure to your data You can just upload files directly from anywhere like a web server RFID device or cell phone mobile device directly into Hadoop They could be images videos or just a bunch of bits They don t have to have a schema with column types and so on which gives you tremendous agility and flexibility Hadoop has a very nice model that I sometimes refer to as schema on read Whereas defining your schema as you re writing the data in limits what you can put in by requiring it to be conformant to the schema that you created Hadoop allows you to define the schema as you re reading stuff out That gives you a lot of flexibility and agility since you can add files that have dynamic parts like JSON or new standards coming up like Avro which is a very good project coming out of the Hadoop project that s similar to protocol buffers from Google and Thrift from Facebook Avro makes files have a schema around them as well but these schemas are semi structured rather than conforming to a strict relational model That said it s also important to point out that structured stuff is a subset of unstructured stuff The fact that Hadoop at its heart is a file system doesn t mean that it can t do
