  • Qt Based Journald API Abstraction (& yet another journald browser)

    On modern Linux systems usually you will find systemd as init system. Along with it, there comes journald as a logging backend with many nice and cool features (which I will not tell you anymore about, the Internet will have answers for you). But also when you are looking on embedded devices with the power of a smart phone or like a Raspberry Pi, journald is a really nice logging data sink for you.

    When analyzing logs of embedded devices, usually you are not working on the device “directly”, meaning not using the tiny konsole application of your smart phone to browse through the logs. Instead, you are either (1) grabbing the full log database from there for offline analysis or (2) you read the logs online via a network stream. Both is easily doable with journald. For the first use case you can simply (please remember to configure journald to use persistent logs!) copy the database from /var/logs/journal and access them on your developer system via “journalctl -D <path>” and get all the nice processing tooling from journalctrl — journalctl is the default CLI frontent for journald. For the second variant, you can start the journal remote service on the target device and receive the online stream of log information on your host system for analysis.

    For the second case there are a few GUI applications available, which nicely solve this problem for you, e.g. qjournalctl (which parses the journalctl CLI input/output) or ksystemlog (yet with the focus of being a generic front-end for various log sinks). Yet, both do not support the parsing of non-system offline logs.

    [...]

    Since my focus originally was on offline logs, those are the type of logs for which the support works quite well right now. But both online local journals (ie. new log entries are attached while the log is open) as well as remote logs will join soon.

  • How partners are helping customers embrace the cloud with Red Hat OpenShift Service on AWS (ROSA)

    Last week, Red Hat and AWS announced the general availability of Red Hat OpenShift Service on AWS (ROSA), a fully managed and jointly supported offering that enables organizations to build, deploy and manage applications with Red Hat OpenShift, delivered as a native AWS service accessible through the AWS Management Console.

    The availability of Red Hat OpenShift Service on AWS gives our customers and partners a managed, self-service option to run OpenShift in the AWS cloud, making it even easier for customers to adopt containers, migrate workloads to AWS and deploy their applications faster.

  • Using cloud technology to create better digital banking experiences

    Defining "the next normal" of a digital business may prove to be as elusive as the proverbial pot of gold at the end of the rainbow. The digital world around is rapidly changing and is straining the systems and processes of banks that created over the last two decades.

    Customers may be increasingly impatient and demanding. As they shift between digital and physical products, services, and channels, banks will need to rapidly pivot to keep them happy. This requires spending as much or more time on shoring up transactional systems as it does on digital applications. For instance, a payment service needs to be connected to customer and account information along with financial crime prevention services and, of course, payment networks. The user interface is important, but it is only one component of the larger customer experience.

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.
