Taming Regular Expressions

Despite their power, regular expressions come with their own challenges. First of all, they have a tendency to quickly become unreadable, so that understanding them becomes a matter of deobfuscation. Furthermore learning how to use them involves a steep curve as they've always been difficult to master.

Simple Regex Language, is the latest addition to the many solutions already at large. An open source project on GitHub, under the MIT License, it takes the radical approach of targeting the very "language" that we use to write regular expressions, completely replacing it with a domain specific counterpart.

But first, let's take a deeper look into the domain specific problem that SRL tries to alleviate. To address the primary issue of unreadability, the /x modifier was introduced, which allowed for the inclusion of white space, line breaks as well as commenting in the regex itself. Under /x the regex engine wouldn't treat those elements as part of the expression to match, therefore allowing their use for the purposes of indentation and self-description.

Serverless JavaScript

We recently joined in an interesting two-hour long conversation about Serverless JavaScript led by Steve Faulkner of Bustle who answered questions on Bustle, the Shep framework, the mindset behind the AWS Lambda infrastructure, and related topics.

The discussion took place on the Sideway conversation-sharing platform on January 6th. Here we present the best takeaways from the session which really should be taken notice of by anyone working on AWS.

Steve Faulkner:
At Bustle we serve over 50 million unique readers per month through a "serverless" architecture based on AWS Lambda and Node.js.  Of course there are still servers but we don't manage them. This shift has allowed us to develop products faster and decreased the cost of our infrastructure. I'll answer any questions about how we made this transition and how it has worked out. I'll also discuss some of the tools and best practises including our open source framework shep

First Hybrid Open-Source RDBMS Powered By Hadoop and Spark

Splice Machine is a novel attempt to merge the best parts of the traditional relational database management systems and their NoSQL counterparts with distributed and in-memory computing based on Hadoop and Spark.

Traditional RDBMS find it tough when faced with massive amounts of data, which they typically handle by scaling up, albeit expensively. Another side effect of the sheer volume of data accumulating from the likes of social media and mobile devices, is that OLTP and OLAP queries carry high performance hits that subsequently have detrimental effects on real time analysis and instant decision making.

Google's Cloud Spanner To Settle the Relational vs NoSQL Debate?

Cloud Spanner is a new proposition for database as a service that emphatically offers "Relational with NoSQL scaling". Will Google come to dominate yet another market?

Once upon a time there was only one kind of database management system, the RDBMS, "R" for relational. Despite its resilience and trustworthiness, it had its shortcomings; it did not scale well, and the relational model it served proved inadequate in the dawn of the Big Data era for handling massive amounts of schema-less, unstructured data.
For this and a few other reasons, a new breed of DBMS's emerged, one that could handle the avalanche of big data, based on the notion of the key-value pair, and doing so by scaling horizontally. But, in order to become versatile, this new breed of management systems had to forgo the safety of the ACID and the cosiness of SQL, both long term partners of the relational model. full article on i-programmer
