  • TellYouThePass ransomware returns as a cross-platform Golang threat [Ed: Microsoft boosters' site tries to associate Go with what people could in theory code using Go, as if it's guilty of it]

    Golang is a programming language first adopted by malware authors in 2019 due to its cross-platform versatility.

  • 8 Best Free and Open Source Java Object-Relational Mapping Software - LinuxLinks

    Object–relational mapping (ORM) is a programming technique for converting data between incompatible type systems using object-oriented programming languages. This creates, in effect, a “virtual object database” that can be used from within the programming language.

    In essence, ORM is a design pattern for converting (wrapping) that data stored within a relational database into an object that can be used within an object oriented language. It creates a layer between the language and the database, helping programmers work with data without the OOP paradigm.

    Compared to traditional techniques of exchange between an object-oriented language and a relational database, ORM often reduces the amount of code that needs to be written. It standardizes interfaces reducing boilerplate and speeding development time. Advocates of ORMs claim they increase productivity, improve application design, reuse code and maintain the application over time. On the other hand, ORM suffers the disadvantage of the abstraction obscuring what’s happening in the code. And over-use of ORM software can produce poorly designed databases.

    There are a good range of ORM software available. Here’s our recommendations summarised in a legendary ratings chart.

  • How to Get Return Code from Process in Python Subprocess Execution?

    A process is a name for a running program. Memory, lists of files, and a program counter that takes account of the instructions being implemented, and a call stack that retains the local variables are all part of each process’s system state. A process normally processes statements one after the other in a single command flow sequence known as the process’s main thread. The program only does one thing at any given moment. Our computer is always running subprocesses. Every action we take on our computer entails activating a subprocess. Even if we are constructing a basic “hello world” program in Python. Even if you have been programming for a while, you might not know the concept of a subprocess. The principles of the subprocess will be covered in this article, as well as how to use the Python subprocess standard library.

  • Arduino IDE Creates Bootable X86 Floppy Disks | Hackaday

    Arguably the biggest advantage of the Arduino ecosystem is how easy it is to get your code running. Type a few lines into the IDE, hit the button, and in a few seconds you’re seeing an LED blink or some text get echoed back over the serial port. But what if that same ease of use didn’t have to be limited to microcontrollers? What if you could use the Arduino IDE to create computer software?

    That’s exactly what boot2duino, a project developed by [Jean THOMAS] hopes to accomplish. As you might have guessed from the name, the code you write in the Arduino is turned into a bootable floppy disk image that you can stick into an old PC. After a few seconds of beeping and grinding your “Hello World” should pop up on the monitor, and you’ve got yourself the world’s biggest Arduino.

  • Moving librsvg's documentation to gi-docgen - Federico's Blog

    Librsvg's documentation tooling is pretty ancient. The man page for rsvg-convert is written by hand in troff, and the C library's reference documentation still uses the venerable gtk-doc.

    As part of the modernization effort, I have turned the man page into a reStructuredText document, and the C API documentation into gi-docgen. This post describes how I did that.

    [...]

    Gtk-doc assumed that magic happened somewhere in developer.gnome.org to generate the documentation and publish it. Gi-docgen assumes that your project publishes it with Gitlab pages.

    Indeed, the new documentation is published there — you can see how it is generated in .gitlab-ci.yml. Note that there are two jobs: the reference job generates gi-docgen's HTML in a public/Rsvg-2.0 directory, and the pages job integrates it with the Rust API documentation and publishes both together.

  • 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.
