Software Development for Infrastructure

Bjarne Stroustrup has another very interesting paper on his website.  Titled Software Development for Infrastructure, it discusses some key ideas for building software that has “…more stringent correctness, reliability, efficiency, and maintainability requirements than non-essential applications.”  It is not a long paper, but offers useful observations and guidelines for building such software systems.

Evolving a language in and for the real world: C++ 1991-2006

c_0Bjarne Stroustrup has great paper on his website titled Evolving a language in and for the real world: C++ 1991-2006. It provides fascinating insights on the development of the language, the challenges involved, and discusses interesting design ideas. If you have even a basic understanding of C++, it’s a such a worthwhile read.

Replicating SQLite using Raft Consensus

raft-logoSQLite is a “self-contained, serverless, zero-configuration, transactional SQL database engine”.  However, it doesn’t come with replication built in, so if you want to store mission-critical data in it, you better back it up. The usual approach is to continually copy the SQLite file on every change.

I wanted SQLite, I wanted it distributed, and I really wanted a more elegant solution for replication. So rqlite was born.

What I wish I’d been told about the JVM

Java_logoJava is the predominant language of Big Data technologies. HBase, Lucene, elasticsearch, Cassandra – all are written in Java and, of course, run inside a Java Virtual Machine (JVM). There are some other important Big Data technologies, while not written in Java, also run inside a JVM.

Examples include Apache Storm, which is written in Clojure, and Apache Kafka, which is written in Scala. This makes basic knowledge of the JVM quite important when it comes to deploying and operating Big Data technologies.
