State of Data Last Week -#39

#analysis – Winner of 2010 Turing AwardLeslie Valiant for Machine Learning – “ introduced the “probably approximately correct” (PAC) model of machine learning that has helped the field of computational learning theory grow, and the concept of holographic algorithms. His earlier work in automata theory includes an algorithm for context-free parsing, which is (as of 2010) still the asymptotically fastest known” (from WikiPedia)

#api – Scraper is a well working Chrome extension for ‘getting data out of web pages and into spreadsheets’

#architecture – Why the legacy BI ‘Best Practice Architecture’ is rapidly getting obsolete – a lot to with innovations around hardware, appliance and storage of data in last decade or so. E.g., price of 1GB storage was $300K in 1981, $0.10 in 2010. (Metaphor/ picture on ‘column-based’ storage is from the first article)

#big_data (and a little boy)– ‘
MIT Scientist Deb Roy captures 90,000 Hours of Video of his son’s first words, graphs it’ – 200 TB of data was captured to track ‘the emergence and refinement of specific words in Roy’s son’s vocabulary’. Deb’s TED 2011 talk is now available

#DBMS – Jay Turner came out with a nifty way to easily capture SQLs that limit scalability by being parsed over and over for transactional Oracle databases

#learning –
FREE – ‘Linked Data: Evolving the Web into a Global Data Space’, book authored by Tom Heath. However, purchase is recommended to ensure more such publication.

#thoughtfulness –
Scott Adams continues boundary less thinking on a ‘future with no data privacy’ – “Privacy has its benefits, but you’re giving up a lot of cool apps

#visualization – enables ‘to easily compare the size of all sorts of artefacts, like objects (e.g. iPad vs. iPad 2), persons (e.g. Obama vs. Sarkozy)



About Nilendu Misra
I love to learn, create and coach. Things that I do well are - Communicating ideas - verbally or through words and diagrams; Problem Solving - Logical or Abstract; Very Large Scale Systems; think about 'Frighteningly Simple' approach first. Things that I intend to do better are - Establishing Stringent Process; Exchanging Tough Feedback; Keeping up with my reading or To-Do list to be able to completely relax.
