  • Cthulhu: New open source chaos engineering tool for Java

    Ready to create a little chaos? xMatters newly open sourced their internal chaos engineering tool. Cthulhu helps developers by automating cross-platform software failure testing. It detects failures automatically and self-heals back to a normal state.
    Meet the newly opened sourced chaos engineering tool: Cthulhu. It helps automate cross-platform software failure testing by simulating different scenarios. The digital service team xMatters open sourced this tool on May 14, 2019. It is now available on GitHub under the Apache License for DevOps team to implement into their workflow.

    Chaos engineering is used by teams to simulate disaster in order to test the reliability or security of a piece of software. This method of testing aims to save time and take a proactive approach to solve issues. Perhaps one of the most well-known examples of this mode of testing is Netflix’s internal tool, Chaos Monkey.

    Add some Lovecraftian horror into the mix; let’s take a look at Cthulhu and what it offers.

  • Open Source Testware for Systematic IoT Testing: Eclipse IoT-Testware

    The project Eclipse IoT-Testware is delivering free open-source test tools and programs for the industry and companies developing Internet-of-Things (IoT) solutions. At TestCon Moscow 2019 Axel Rennoch, senior scientist at Fraunhofer FOKUS, spoke about quality assurance for IoT.

    Today and in the future, IoT products and solutions will be omnipresent; they do appear in most of our daily environments at home, in industry, agriculture or traffic situations, said Rennoch. IoT solutions are generally characterized by openness, distribution, dynamics, scaling, and a long service life, argued Rennoch. IoT devices and services should be tested with a focus on conformance, interoperability, robustness, and security.

  • Should IT Professionals Learn to Code?

  • RQuantLib 0.4.9: Another small updates

    A new version 0.4.9 of RQuantLib reached CRAN and Debian. It completes the change of some internals of RQuantLib to follow suit to an upstream change in QuantLib. We can now seamlessly switch between shared_ptr<> from Boost and from C++11 – Luigi wrote about the how and why in an excellent blog post that is part of a larger (and also excellent) series of posts on QuantLib internals.

  • 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.
