In the quest to maximise performance of your site it is tempting to turn to the latest and greatest, shiniest, whiz-bang tools. Working with the latest technologies comes with a price – they don’t call it bleeding edge for naught! Zef Hemel writes of his experience with Cloud9 and their implementation of the hottest solution at the time – node.js and redis DB. There are many interesting technological problems that come with being a pioneer, and solving these may not serve your mission as well as using older, stable, well understood tools.

Evernote’s lessons and tips in moving from their old mySQL/InnoDB data warehouse to the new Hadoop/Hive – ParAccel – JasperReports solution. Working with the newest technologies means hitting more uncharted edge scenarios and not being able to reuse the discoveries of other pioneers. But in the end Evernote comfortably handles 200 million API events per day to work with the hundreds of terabytes of online data.

SQL 5.0 brought us the index merge optimiser plan. At first glance, utilising multiple keys should speed things up considerable. Ernie Souhrada writes about how In practice this optimisation often isn’t optimal.
Google Pagespeed has an experimental memory locking feature which is a lot faster than file locking. Interestingly, some sites have faster page load times with pagespeed with memory locking, than without pagespeed at all.

Testing site performance and generating synthetic benchmarks provides valuable feedback to developers. Real User Monitoring provides real external metrics. Enhancing the synthetic test to introduce external factors such as latency and packet loss is achievable on any testing platform. Joe Miller explains how to do this WAN simulation on Mac OSX using freely available tools which are included in ‘dummynet’ from FreeBSD.

Wearable devices have come of age. The primary applications of wearables so far have been "the Quantified Self" or the tracking of one's fitness and health status. We propose the evolution of wearables into social and emotional communication devices. Our BE(tm) sensor uses light to visualize the skin conductance response. Our sensors are very inexpensive and can be massively distributed to audiences or groups of any size, in order to gauge reactions to performances, video, or any kind of presentation. In her session at @ThingsExpo, Jocelyn Scheirer, CEO & Founder of Bionolux, will discuss ho...

The explosion of connected devices / sensors is creating an ever-expanding set of new and valuable data. In parallel the emerging capability of Big Data technologies to store, access, analyze, and react to this data is producing changes in business models under the umbrella of the Internet of Things (IoT). In particular within the Insurance industry, IoT appears positioned to enable deep changes by altering relationships between insurers, distributors, and the insured. In his session at @ThingsExpo, Michael Sick, a Senior Manager and Big Data Architect within Ernst and Young's Financial Servi...

The Internet of Things (IoT) is causing data centers to become radically decentralized and atomized within a new paradigm known as “fog computing.” To support IoT applications, such as connected cars and smart grids, data centers' core functions will be decentralized out to the network's edges and endpoints (aka “fogs”). As this trend takes hold, Big Data analytics platforms will focus on high-volume log analysis (aka “logs”) and rely heavily on cognitive-computing algorithms (aka “cogs”) to make sense of it all.

The industrial software market has treated data with the mentality of “collect everything now, worry about how to use it later.” We now find ourselves buried in data, with the pervasive connectivity of the (Industrial) Internet of Things only piling on more numbers. There’s too much data and not enough information. In his session at @ThingsExpo, Bob Gates, Global Marketing Director, GE’s Intelligent Platforms business, to discuss how realizing the power of IoT, software developers are now focused on understanding how industrial data can create intelligence for industrial operations.

Operational Hadoop and the Lambda Architecture for Streaming Data Apache Hadoop is emerging as a distributed platform for handling large and fast incoming streams of data. Predictive maintenance, supply chain optimization, and Internet-of-Things analysis are examples where Hadoop provides the scalable storage, processing, and analytics platform to gain meaningful insights from granular data that is typically only valuable from a large-scale, aggregate view. One architecture useful for capturing and analyzing streaming data is the Lambda Architecture, representing a model of how to analyze rea...

The true value of the Internet of Things (IoT) lies not just in the data, but through the services that protect the data, perform the analysis and present findings in a usable way. With many IoT elements rooted in traditional IT components, Big Data and IoT isn’t just a play for enterprise. In fact, the IoT presents SMBs with the prospect of launching entirely new activities and exploring innovative areas. CompTIA research identifies several areas where IoT is expected to have the greatest impact.
