Simple but very powerful new feature: write your own functions that can be used in BigQuery queries like built-in ones.

Building our new data center near Eemshaven, The Netherlands. Yes, it doesn't look like much yet but hundreds of workers are hard at work. A nearly finished portion of the shell is on the left and some cooling towers are being built near the center. Lots of windmills in the background, one reason for choosing this location -- this data center will be powered by 100% wind power.

I wonder why the cooling towers are being built near the center ... weather/humidity ?

An object throwing off the tyranny of function forces us to reevaluate it in unfamiliar contexts!  Wifi routers know this all too well.

14,000 commits from 400 contributors in one year -- glad we started it :-)  Now ready for production use, be that on GCP or on your own cluster.

A simple demo of how to analyze logs data without any programming (or installing any software) using BigQuery.

Yesterday we published more details on the past decade of our cluster networking work, with lots of pictures (see article below).  For the technical details see this blog post: http://googleresearch.blogspot.com/2015/08/pulling-back-curtain-on-googles-network.html and for the gory details this SIGCOMM paper: http://static.googleusercontent.com/media/research.google.com/en//pubs/archive/43837.pdf.

Never again write separate code for batch and real-time analytics.  Customer quote: "It took half a day to rewrite something that had previously taken over six months to build using Spark".  And it's 2-3x faster than Hadoop for batch jobs...
 
Good news. Google Cloud Dataflow is GA.

When it comes to #bigdata, simpler is better. Based on Google innovations like MapReduce and FlumeJava, Cloud Dataflow takes the complexity out of batch and streaming big data processing. Learn more about it and the Cloud Pub/Sub GA: http://goo.gl/ZOJzCH

A good description of recent work on making Flash more secure.  The only sentence I'd take issue with is " [because Flash is built into Chrome] a Flash vulnerability makes all Chrome users vulnerable".  That's not really correct -- since many webpages use Flash and Flash is supported by all browsers, a Flash vulnerability is bad for every browser (and user). Chrome "sandboxes" Flash into a separate container and thus can prevent some (but not all) Flash bugs from harming your computer.  But really, Flash needs a major investment in security from Adobe.

Does that mean that flash is going to live forever?

I'm surprised they didn't like it in Tokyo:

(The pictures tell the story.) I actually like both of them, so am looking forward to trying Kalles Kaviar.
