  1. Learn Linux, 101: Localisation and internationalisation
    Learn how to use locale and time zone settings to put your Linux system in the right time and place. You can use the material in this tutorial to study for the LPI 102 exam for Linux system administrator certification or to learn for fun.
  2. Put a Linux-based chess app on the cloud with Bluemix and IBM Containers
    Build a Docker container that uses WebSockets to expose an existing Linux CLI chess engine as a cloud service. This tutorial shows step-by-step the process for building a Docker container and deploying it as a running container on IBM Containers for Bluemix. It includes sample code and a JavaScript chess game that runs in a browser and illustrates how to consume the WebSocket-based service. You can apply the methods demonstrated to containerize almost any pipe-based Linux application and leverage them as cloud services on Bluemix.
  3. SAS software with Hortonworks Data Platform (HDP) running on IBM POWER8
    This article describes how to set up an environment where SAS can access and analyze data stored on Hortonworks Data Platform (HDP) using SAS/ACCESS Interface to Hadoop. The environment is running on IBM POWER8 processor-based servers.
  4. OpenPOWER firmware with Intelligent Platform Management Interface (IPMI) features
    This article explains the various OpenPOWER aspects (such as system firmware usage, controlling, and debugging) that are related to developers and test engineers.
  5. Continuous monitoring of server resources utilization using custom scripts
    Monitoring IT infrastructure is essential to ensure its stability. Choosing an efficient, scalable, customizable, and light-weight solution for this has always been a challenge with changing requirements. Custom scripts can be used to achieve this smartly unlike the agent-based monitoring method in which all data defaulted by the monitoring tool used will be collected. This article describes the custom script method for monitoring system resources. In this method, the data collector(s) scripts running on data collector node will poll the target systems for data and so can decide on what data to be pulled.
  6. Open Source POWER Availability Tool
    Search for Linux open source packages that run on the IBM POWER architecture.
  7. OpenPOWER secure and trusted boot, Part 2: Protecting system firmware with OpenPOWER secure boot
    Protection of system firmware against malicious attack is paramount to server security. If an attacker is able to inject malicious code at the firmware level, no security measure at the operating system level can fully guarantee the trust of the system. IBM OpenPOWER servers support secure boot of system firmware to ensure the system boots only authorized firmware. When the system boots, each firmware component is verified against a cryptographic signature and integrity-checked against a secure hash of the component. If any check fails, secure boot prevents the system from booting until the problem is corrected.
  8. Learn Linux, 101: Maintain the integrity of filesystems
    Learn how to check the integrity of your Linux filesystems, monitor free space, and fix simple problems. Use the material in this tutorial to study for the Linux Professional Institute (LPI) 101 exam for Linux system administrator certification -- or just to check your filesystems and keep them in good working order, especially after a system crash or power loss.
  9. An open source solution for dockerizing STAF and LTP on IBM Power Systems
    STAF and LTP is a widely used regression test combination to validate the behavior of Linux kernel and glibc components. This article describes how to build a STAF and LTP Docker image. By using this image, you can create containers that test the Linux kernel and glibc components.
  10. Digital Business Start trial offering for IBM Power Enterprise Systems using EnterpriseDB (EDB) Postgres Advanced Server
    This article describes how to quickly and easily install and configure EnterpriseDB Postgres Advanced Server with Linux on Power architecture, namely RHEL 7.2 LE. Although it is targeted towards customers who have eligible dark core resources on IBM Power Enterprise Servers, the installation instructions are valid for most IBM Power servers.
