  • How to Detect and Defeat Cryptominers in Your Network [Ed: Microsoft Windows TCO]

    Cryptojacking software can also attempt to blend in by pretending to be a process that belongs to a legitimate application. They can use techniques such as DLL sideloading where a malicious DLL replaces a legitimate DLL. The DLL is called by a bone fide application when it launches, or a doppelgänger application that has been downloaded behind the scenes.

    Once it is called, the fraudulent DLL launches a cryptomining process. If the high CPU load is noticed and investigated, it appears that a legitimate application is misbehaving and performing in an adverse fashion.

  • Abiola Ajadi: Outreachy-Everyone Struggles! [Ed: Outreachy seems to be picking people who don't know how to code and outsource things to Microsoft's proprietary software instead of promoting Free software]

    Three weeks into my internship and it’s been great so far with Awesome Mentors. I am currently learning a new Language which is Ruby and this is the perfect time to remind myself that everyone struggles! I struggled a bit getting farmiliar with the codebase and pushing my first merge request during the internship. I won’t say i have a perfect understanding of how everything works, but i am learning.

  • Building an ODT on the command line

    Answering my own question Isn't there an easier way to do this?, I wrote a shell script that starts with a YAD form dialog. After I enter the strings in their appropriate form boxes, the script does the three jobs listed above automatically.

    An unusual aspect of my script is that it creates a formatted ODT without involving a GUI word processor. To do this I use LibreOffice Writer to convert an HTML file to an ODT on the command line. The HTML doesn't have to be up-to-date, either, or use CSS for styling. You and I may have forgotten (or never knew) the HTML of 25 years ago, but it's apparently still in the Writer code base.

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.
