    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. It is built on Google’s BigTable architecture, with support for distribution, replication, failure detection and load balancing using Apache ZooKeeper.

  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.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
