  • PASE Versus ILE: Which Is Best For Open Source?

    Open source has emerged as a driver of innovation in the past 20 years, and has greatly accelerated technological innovation. The proprietary IBM i platform has also benefited from this trend, thanks in large part to the capability to run Linux applications in the PASE runtime. But some members of the IBM i community are concerned that the fruits of the open source innovation have not tasted quite as sweet as they do on other platforms.

    Linux was the original breakout star in open source software, and so it should be no surprise that the vast majority of software developed with the open source method is designed to run on the Linux operating system and associated open source componentry, including the Apache Web Server, MySQL database, and PHP, the so-called LAMP stack (although you can substitute other pieces, like the Postgres and MariaDB databases and languages like Perl, Python, and Node.js to create other clever acronyms).

    The IBM i operating system can run Linux applications through PASE, the AIX runtime that IBM brought to OS/400 so many years ago. Getting Linux applications to run on PASE requires that they’re first ported to AIX, which is often not too much work, since Linux is a variant of Unix, just like AIX.

  • How Instagram is scaling its infrastructure across the ocean

    To prevent quorum requests from going across the ocean, we're thinking about partitioning our dataset into two parts: Cassandra_EU and Cassandra_US. If European users' data stores are in the Cassandra_EU partition, and U.S. users' data stores are in the Cassandra_US partition, users' requests won't need to travel long distances to fetch data.

    For example, imagine there are five data centers in the United States and three data centers in the European Union. If we deploy Cassandra in Europe by duplicating the current clusters, the replication factor will be eight and quorum requests must talk to five out of eight replicas.

    If, however, we can find a way to partition the data into two sets, we will have a Cassandra_US partition with a replication factor of five and a Cassandra_EU partition with a replication factor of three—and each can operate independently without affecting the others. In the meantime, a quorum request for each partition will be able to stay in the same continent, solving the round-trip latency issue.

  • Two software companies, fed up with Amazon, Alibaba and other big cloud players, have a controversial new plan to fight back

    Every year, large cloud companies like Amazon rake in billions of dollars— but some of their most popular cloud services comes from repackaging software projects created by other, smaller companies.

    Amazon is repackaging what's known as "open source" software, which is software that is given away for free, meaning Amazon has every legal right to use it in this way. For instance, since 2013, Amazon had been offering the open-source database Redis as part of a popular cloud service called ElastiCache.

  • Running Your Own Database-as-a-Service with the Crunchy PostgreSQL Operator

    One reason why enterprises adopt open source software is to help free themselves from vendor lock-in. Cloud providers can offer open source “as-a-service” solutions that allow organizations to take advantage of open source solutions, but this in turn has can create a new type of trap: infrastructure lock-in.

    Many organizations have adopted Kubernetes to give themselves flexibility in where they can deploy their services in the cloud, without being locked into one provider. Some people express concerns that this instead creates “Kubernetes lock-in,” but because Kubernetes is open source and has both widespread support and active development, it should be no different than adopting Linux as your operating system.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
