I get a lot of information from there and Wikipedia.

That is a nice addition to the book list. We should talk about Ian Stuart some time. Get Emotion Machines, if you have time to read it. Another great topic for long discussions.

I also liked the book Taming the infinite by Ian Stewart

Optimizing movement of data itself needs to be part of the solution. You are not moving all the data but parts of it.

how the New York Times used Amazon’s cloud to great effect. The Times’ Derek Gottfrid blogged about it 6 weeks ago. But I think it’s worth revisiting.

His challenge was to turn 11 million archived articles, Times coverage from 1851 to 1980, into pdf files so that all readers could access them quickly from the Web. I won’t go into detail here, but he implemented the open-source software, Hadoop, bought computing power on Amazon’s cloud, and he did the entire work in one day. That’s something that would have taken weeks, or longer, on in-house machines at most publishing companies. http://buswk.co/AgDXC0

Difficult to move data around (from servers to the cloud), path of least resistance is to move computation to data, (almost as if data has mass/gravity).

If data is on customer servers, they will prefer to work on it themselves. Alternative is to help source the data, reach criticality and become a data black hole!

Taking a large job would necessarily involve getting access to data, and moving data around has a cost, how should one approach this aspect of the problem ?

I am not sure whether companies like Cloudera actually provide this service. Cloudera uses Hadoop. I wonder whether there is a list of such providers in Amazon (on top of the elastic hadoop services).

If you are interested, let me know. Will do some research and get back to you.

Very few people have this experience. Wonder how one can close that gap? Is on the job experience the only option.

a) Strong foundation is a must before one proceeds to higher lessons.

b) Patient, persistent practice alone can guarantee such strong foundation.

Cannot agree more.

However, the next level of analysis where you take external data and start hypothesizing and characterizing how external forces operate on the business requires a thorough understanding of the business and its externalities and not to forget its strategic planning. As very few people in the organization are privy to the strategic planning dimension, the deep analytics to derive value is localized at the top of the organization.

This explains why the deep analytics space has bifurcated in the super high-end driven by IBM and SAS for the FORTUNE 500, and the super low-end driven by scrappy entrepreneurs in the consumer web 2.0 space. There is no opportunity for deep analytics in the missing middle. Otherwise stated, there is sufficient talent already being educated for the few spots in the high-end, and the low-end is defining/inventing it as they go along.

- Listen to podcasts (while driving specifically). Check out the ACast app.
- Read EBooks (Kindle mostly)
- Playing around with HDR photos
- Online Dictionary app when reading books
- Quickly convert timezones
- RSS Reader (gReader)
- Take photocopies (every govt/non-govt entity needs photo copies of something or the other)
- Send Photos/Videos to my TV (Skifta app via DLNP) when watching with family
- Also as a Remote to my Samsung TV (SamyGo Remote)
- Making and keeping track of grocery lists
- Some times find nearby places using Google’s places app
- Re-install modified & latest OS when getting bored
- Keeping track of Trip details using TripCase or similar software
- Watch lots of Ted.com videos
- Occasionally, use SoundHound to identify a song being played and add to my collection
- Sometimes, follow the exercise apps. Doesn’t happen very often :-)
- Checkin using Foursquare when I land up in some unknown places
- When in balcony or terrace, track any visible satellites (Satellite AR app). Unsuccessful so far
- yes, also make phone calls :-)

I can imagine a kind of ebook reader that lets a small piece of software embedded in every book and provide a sandbox framework for that piece of software to run as we are reading the book. Some interesting possibilities…
