I am not saying that the current state of NoSQL tools is optimal. But expecting to see an unification of heterogenous data systems based on a structured query language feels like the wrong expectation.

Visual Basic is the exception. ↩

In 1.0 we added the ability to build secondary indexes on your data stored in Riak. We developed this functionality because, quite frankly, people needed a more powerful way to query their data.

So it's with particular interest that I've watched a new incarnation of server side JavaScript take hold in the developer community. Node.js is still young, but undeniably exciting in that it offers a highly scalable, event-driven I/O model for building networked applications. Node.js is built to run on V8 , which is an open source JavaScript engine developed by Google that compiles JavaScript into native machine code before execution, resulting in extremely …

Problem is, I've not found a single DOI for any article in Annals and Magazine of Natural History that actually works. If you try and resolve the DOI for Wallace's paper, doi"10.1080/037454809495509 , you get the dreaded "Error - DOI not found" web page. So something like 20,000 DOIs simply don't work. The only way to make the DOI work is append it to "http://www.tandfonline.com/doi/abs/", e.g. http://www.tandfonline.com/doi/abs/10.1080/037454809495509 …

A tuning test bed : we can easily try changes on our database reader first, make it writer, and ensure things are working. If things go south, it's just a single command to return to the previous writer.

Zero downtime schema changes (almost) : One of the big headaches of a decently-sized web app is making large database schema changes. These can take a while on a live database server, either locking tables or slowing down database performance considerably. With MMM , you can make large …
