    Apache Cassandra is one of the most popular databases used in artificial intelligence to help create robots. With the ability to scale up quickly using commodity hardware, Cassandra could become one of the primary data storage systems that will power future robotic data management devices.

    Apache Cassandra is a NoSQL database. With the addition of the Apache Thrift interface, Cassandra can be used to store and manage data without the use of SQL, while allowing developers to use familiar application development protocols like REST and Thrift.

    Cassandra was primarily developed by Facebook engineer Prashant Malik. The database was named after the wife of a co-founder of Facebook, who died in a car accident in 2008.

  10. Linux Fu: Bash Strings | Hackaday

    If you are a traditional programmer, using bash for scripting may seem limiting sometimes, but for certain tasks, bash can be very productive. It turns out, some of the limits of bash are really limits of older shells and people code to that to be compatible. Still other perceived issues are because some of the advanced functions in bash are arcane or confusing.

    Strings are a good example. You don’t think of bash as a string manipulation language, but it has many powerful ways to handle strings. In fact, it may have too many ways, since the functionality winds up in more than one place. Of course, you can also call out to programs, and sometimes it is just easier to make a call to an awk or Python script to do the heavy lifting.
