  • Top 5 options for Linux certifications

    Linux certifications present an interesting mix of distribution- and brand-agnostic credentials, as well as vendor-specific ones. Many of these offerings provide data center professionals with defined pathways to learn, use and master Linux OS management, features and potential Linux use cases.

    Other programs are more ad hoc and specific to certain IT roles, such as systems engineers or IT administrators, but they go beyond self-taught curriculums and forums. Each program includes coursework and an exam. Depending on the certification, admins can buy everything as a bundle or pay separately for study materials and exams.

  • SimpleMailQt v2.0.0-beta1

    On my last post I talked about the new async simplemail-qt API that I wanted to add, yesterday I finished the work required to have that.

    SMTP (Simple Mail Transfer Protocol) as the name says it’s a very simple but strict protocol, you send a command and MUST wait for the reply, which is rather inefficient but it’s the way it is, having it async means I don’t need an extra thread (+some locking) just to send an email, no more GUI freezes or an HTTP server that is stalled.

    The new Server class has a state machine that knows what reply we are waiting, and which status code is the successful one. Modern SMTP servers have PIPELING support, but it’s rather different from HTTP PIPELING, because you still have to wait for several commands before you send another command, in fact it only allows you to send the FROM the RECIPIENTS email list and DATA commands at once, parse each reply and then send the mail data, if you send the email data before you are allowed by the DATA command the server will just close the connection.

  • Plasma 5 for Slackware – November ktown release

    Dear all, today I released KDE-5_19.11 and it comes with some upgrades to official Slackware packages. Don’t worry – Pat Volkerding kindly added the shared libraries of the official Slackware packages to aaa_elflibs, so if you have been updating your Slackware-current installation properly then nothing will break when you update Slackware’s exiv2 and LibRaw packages to the newer versions contained in the November release of ‘ktown‘.
    Official Slackware package updates for exiv2 and LibRaw will come sometime soon, but it will require Pat to recompile several other packages as well that depend on exiv2 and/or LibRaw. I needed the new exiv2 to compile the latest digikam, so I was pleased with Pat’s cooperation to make this a smooth ‘ktown‘ upgrade for you.

  • Vulnerability Values Fluctuate Between White, Grey and Black Hats

    A black hat selling vulnerabilities can make as much money as a white hat researcher using bug bounty programs, or a grey hat working for a nation state doing reverse engineering.

    Speaking at a Tenable conference in London last week, director of research Oliver Rochford said that to have people do vulnerability research is expensive, and all of the white, black and grey markets are symbiotic, as despite the difference between being legal and illegal, the different factors “mirror each other as it starts with vulnerability discovery.”

    Rochford said that this “shows how professional cybercrime has become,” pointing to the fact that the main difference between criminal and legal sides are ethics. In one slide, Rochford pointed out vulnerability discovery, exploit research and development are the same for both offense and defensive sides, while the differences fall at the "operationalization" side, where offensive sides look at espionage, sabotage and fraud, while defense sides look at threat intelligence and compensating control adaptation.

    In his research, Rochford showed that in some cases you can earn more as a white hat vulnerability manager than as a black hat, with a black hat able to earn around $75,000 in this sort of work. Rochford said this “is achievable and attractive” and while it was more lucrative to do it legally, if it is not “it is a way to make a living.”

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.
