Let’s go a little further in our CouchDb storage system with PHP. I will show you why. We have some files using PHP’s filesystem functions and we want to change them to the new interface with the Nov\CouchDb\Fs library. We’ve got the following code:
As a customer and fan of Amazon, I've been watching the company grow and develop for a while. Based on my experiences and observations, I've come up with a picture of the not-so-distant future that I believe will (mostly) come to pass.
The code is horrible and the visualisations quite possibly misleading, but I’m dead tired and there are a couple of tricks in the following R code that I want to remember, so here’s a contrived bit of fumbling with some data of the form . . .
I recently started playing around with NoSQL databases as became interested in MongoDB. Here is a great video tutorial that will get you quickly introduced to NoSQL and the MongoDB application. It covers how NoSQL is different from typical RDBMS platforms and schemas, and how data is stored in MongoDB.
Data Gravity featured in this year’s EMC World keynote. But beyond the observation that large or valuable agglomerations of data exert a pull that tends to see them grow in size or value, what is a recognition of Data Gravity actually good for?
Web performance is a growing field within the greater operations community. This year it gained its own WebPerfDays – modeled after the highly regarded DevOpsDays – both of which followed the main Velocity conference.
The Apache Hadoop framework enables distributed processing of very large data sets. Hadoop is written in Java, and has limited methods to integrate with “mapreducers” written in other languages. This lab demonstrates how you can use JNBridgePro to program directly against the Java-based Hadoop API to create .NET-based mapreducers.
I recently came across a very interesting post about CDN testing by Jonathan Klein, someone I respect tremendously in the Web Performance world. During his tests with Webpagetest he was unable to “see” the value provided by the CDN on his site.
