AZ Business Magazine December 2008 AZ Business Magazine November/December 2012 Bring on the HEAT The Valley of the Sun has created the perfect climate for tech startups. Don’t believe me? What if I told you the Valley is almost as prolific as Silicon Valley for producing tech startup companies? Questionnaire design Perhaps the most important part of the survey process is the creation of questions that accurately measure the opinions, experiences and behaviors of the public. Accurate random sampling and high response rates will be wasted if the information gathered is built on a shaky foundation of ambiguous or biased questions. Creating good measures involves both writing good questions and organizing them to form the questionnaire. Questionnaire design is a multistage process that requires attention to many details at once.
Premise Data General How many countries do you operate? We’re currently in more than 30 countries across six continents. How do you decide which countries you’ll start a network in next? These decisions are generally customer-driven depending on their data needs. Interview with Rick Smolan on ‘The Human Face of Big Data’ Manu: Rick, can you tell us a bit about yourself? I saw in your TED talk that you used to be a photo journalist, so how did you get started on this journey? Rick Smolan: Yes, I was always very curious as a person so it’s interesting that I’d end up in a job where I get paid to be curious. As you saw in the TED talk, I went from being a journalist where I work for other people who set the agenda, to the fortunate position of being able to steer my own ship. And now, when I get curious about something I’m able to invite my heroes, my peers and some young journalists along.
Redshift Performance & Cost At Airbnb, we look into all possible ways to improve our product and user experience. Often times this involves lots of analytics behind the scene. Our data pipeline thus far has consisted of Hadoop, MySQL, R and Stata. We’ve used a wide variety of libraries for interfacing with our Hadoop cluster such as Hive, Pig, Cascading and Cascalog. SQL Language for management and use of relational databases SQL ( S-Q-L,[4] "sequel"; Structured Query Language)[5][6][7] is a domain-specific language used in programming and designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS). It is particularly useful in handling structured data, i.e. data incorporating relations among entities and variables. SQL offers two main advantages over older read–write APIs such as ISAM or VSAM.
MapReduce Tutorial This section provides a reasonable amount of detail on every user-facing aspect of the MapReduce framework. This should help users implement, configure and tune their jobs in a fine-grained manner. However, please note that the javadoc for each class/interface remains the most comprehensive documentation available; this is only meant to be a tutorial. Let us first take the Mapper and Reducer interfaces. Applications typically implement them to provide the map and reduce methods. We will then discuss other core interfaces including JobConf, JobClient, Partitioner, OutputCollector, Reporter, InputFormat, OutputFormat, OutputCommitter and others. HDFS Architecture Guide Introduction The Hadoop Distributed File System (HDFS) is a distributed file system designed to run on commodity hardware. It has many similarities with existing distributed file systems.
