Live video is very demanding. At Justin.tv, with less than 250 ms delay required of a system that sees 30 hours per minute of video uploaded and daily peak bandwidth of 110 Gbps, the system has to be robust, scalable, and high-performance. This interview with Kyle Vogt, Justin.tv Founder and VP of Engineering, outlines how they do it.

Javier Alonso explores a few basic options for configuring InnoDB logging to improve performance.
Author: Dimitri Kravtchuk.
With the new changes of InnoDB code supporting OLTP read-only performance and full text search (FTS), Kravatchuk wonders if it can now replace MyISAM. This article covers his extensive tests to discover that InnoDB performs better in most, but not all, areas. FTS is notably now much better in InnoDB than MyISAM.

In this comparison of fractal tree versus MongoDB indexes, inserts are quicker with fractal tree indexes on tables over about 250,000 inserts in this test environment. In fact the test to 5 million inserts had to be abandoned as Mr. Callaghan didn’t have the 2 weeks MongoDB would have needed to do it!

Etsy’s latest quarterly performance report shows they are keeping up well with performance needs. Highlighted is the appropriate use of both real user monitoring (RUM) and synthetic test metrics as well as importance of hardware upgrades.
Author: Joshua Bixby.
Real user monitoring (RUM) is starting to come into play at a high rate. RUM data shows what’s happening in the real world with all its variables and is useful to anyone outside the internal devops team to know how users are experiencing the site. (DevOps have more use for synthetic data with limited variables)

Does your application architecture include Message Queues to feed work items to backend batch processing such as “Update Product Inventory” or “Send out Notification Emails”? Message Queues work well in these use cases as they decouple your system components and allow your backend processing to asynchronously process requests. Is your XML implentation working as well as it can? This case study shows a 1000% performance increase simply by changing the XML parser.

As enterprises work to take advantage of Big Data technologies, they frequently become distracted by product-level decisions. In most new Big Data builds this approach is completely counter-productive: it presupposes tools that may not be a fit for development teams, forces IT to take on the burden of evaluating and maintaining unfamiliar technology, and represents a major up-front expense. In his session at @BigDataExpo at @ThingsExpo, Andrew Warfield, CTO and Co-Founder of Coho Data, will dis...

Eighty percent of a data scientist’s time is spent gathering and cleaning up data, and 80% of all data is unstructured and almost never analyzed. Cognitive computing, in combination with Big Data, is changing the equation by creating data reservoirs and using natural language processing to enable analysis of unstructured data sources. This is impacting every aspect of the analytics profession from how data is mined (and by whom) to how it is delivered. This is not some futuristic vision: it's ha...

Gamification is “the process of adding games or game-like elements to something (as a task) so as to encourage participation.” Further, gamification is about bringing game mechanics – rules, constructs, processes, and methods – into the real world in an effort to engage people. In his session at @ThingsExpo, Robert Endo, owner and engagement manager of Intrepid D...

WebRTC has had a real tough three or four years, and so have those working with it. Only a few short years ago, the development world were excited about WebRTC and proclaiming how awesome it was. You might have played with the technology a couple of years ago, only to find the extra infrastructure requirements were painful to implement and poorly documented. This probably left a bitter taste in your mouth, especially when things went wrong.
