The shortcomings and drawbacks of batch-oriented data processing were widely recognized by the Big Data community quite a long time ago. It became clear that real-time query processing and in-stream processing is the immediate need in many practical applications. In recent years, this idea got a lot of traction and a whole bunch of solutions like Twitter’s Storm, Yahoo’s S4, Cloudera’s Impala, Apache Spark, and Apache Tez appeared and joined the army of Big Data and NoSQL systems.

I think Jason Grigsby was perhaps the first to publicly point out that simply setting a percentage width on images was not enough, you needed to resize these images as well. He showed that if you served appropriately sized images on the original responsive demo site, you could shave 78% off the weight of those images (about 162kB) on small screens.
Product management was never a formal responsibility; it just sort of happened. Early on, it was driven by what the technical wizards came up with. But the magic left the development team years ago: it had been gutted by several rounds of staff cuts that took the garrulous personalities and innovative thinkers. It took the wind from development's sails: those who were still on the payroll were just happy to have kept their jobs.

Something irks me about the phrase “semantic HTML” The intent is clear enough — using HTML in ways that are readable, using plain language to describe things. But that’s not what “semantic” means. We might as well be saying “well written” or “copy edited” They’d be closer fits.
