Adobe has packaged HBase in Docker containers and uses Marathon and Mesos to schedule them—allowing us to decouple the RegionServer from the host, express resource requirements declaratively, and open the door for unassisted real-time deployments, elastic (up and down) real-time scalability, and more. In this talk, you'll hear what we've learned and explain why this approach could fundamentally change HBase operations.
HBase 1.0 is the new stable major release, and the start of "semantic versioned" releases. We will cover new features, changes in behavior and requirements, source/binary and wire compatibility details, and upgrading. We'll also dive deep into the new standardized client API in 1.0, which establishes a separation of concerns, encapsulates what is needed from how it's delivered, and guarantees future compatibility while freeing the implementation to evolve.
Flipboard services over 100 million users using heterogenous results including user generated content, interest profile, algorithmically generated content, social firehose, friends graph, ads, and web/rss crawlers. To personalize and serve these results in real time, Flipboard employs a variety of data models, access patterns and configuration. This talk will present how some of these strategies are implemented using HBase.
Speakers: Kevin O'Dell, Aleksandr Shulman & Kathleen Ting (Cloudera)
From supporting the 0.90.x, 0.92, 0.94, and 0.96 HBase installations on clusters ranging from tens to hundreds of nodes, Cloudera has seen it all. Having automated the upgrade paths from the different Apache releases, we have developed a smooth path that can help the community with upcoming upgrades. In addition to automation best practices, in this talk you'll also learn proactive configuration tweaks and operational best practices to keep your HBase cluster always up and running. We'll also walk through how to contain an application bug let loose in production, to minimize the impact on HBase posed by faulty hardware, and the direct correlation between inefficient schema design and HBase performance.
Digital Library Collection Management using HBaseHBaseCon
Speaker: Ron Buckley (OCLC)
OCLC has been working over the last year to move its massive repository to HBase. This talk will focus on the impetus behind the move, implementation details and technology choices we've made (key design, shredding PDFs and other digital objects into HBase, scaling), and the value-add that HBase brings to digital collection management.

Profilul utilizatorului roman de internet: femeie de 20-24 de ani, cu studii ...trafic.ro
Profilul utilizatorului roman s-a modificat fata de anul trecut, internetul romanesc fiind dominat de femei, cu varsta cuprinsa intre 20 si 24 ani, ce-si petrec cel mai mult timp in Capitala.
Acestea sunt rezultatele campaniei de Studii demografice trafic.ro derulata in perioada 25 mai - 20 iunie, pe 2058 de site-uri din Romania, pe un esantion reprezentativ de 42.000 de respondenti.
Anul acesta, batalia sexelor este castigata de femei (53%), care au inregistrat aproximativ 6% procente in plus fata de utilizatorii de sex masculin (47%). Astfel, putem spune ca structura pe sexe a utilizatorilor de internet, reflecta structura generala a populatiei (52.6% femei conform INSSE). Din totalul respondentilor, 50% sunt necasatoriti, surclasand-i pe cei care prefera institutia casatoriei sau cei care locuiesc cu partenerul (44%). Restul procentajului se imparte intre cei cu statutul de vaduv(a) si divortat(a).
Bogdan Grigore ne povesteste la Optimism 2010 despre cum cauta romanii pe internet in 2010 fata de 2009. De exemplu, cautarile pentru "gratis" au crescut de aproximativ 2 ori.
