  • The cmake-project Script

    If you ever need to create a project around a single C++ file (or just a few C++ files) in CMake, as you might for quick test cases, you might find it tedious to write a CMakeLists.txt file by hand every time. To make this easier, I’ve written a script called cmake-project that you can use to generate an initial CMakeLists.txt for you. Similar to qmake -project, it allows you to quickly create a project around a single or just a few C++ files. In addition, it automatically adds a link to Qt Widgets when the code uses QApplication.

    A few special features that come with CMake are support for many languages (like Fortran, CUDA, and Objective-C), native support from many IDEs (Qt Creator and Visual Studio XCode), many active contributors, many out-of-the-box configuration checks, use of non-recursive make for faster build times, and out-of-the-box support for Ninja for even faster build times. These features are a few of the reasons why Qt 6 switched from QMake to CMake.

    Add the cmake-project script on top of all these fantastic features and you can enjoy the only feature people miss from QMake while working in CMake. In turn, your productivity will be better than ever!

  • Linux X86 Assembly – How To Test Custom Shellcode Using a C Payload Tester

    In the last blog post in this series, we created a tool to make it easy to build our custom payloads and extract them. However, what if we want to test them before trying to use them? It seems like a good idea to make sure it works before you include it in an exploit. Testing it first would at least let you know that it works and reduce troubleshooting surface if the exploit fails. Today we are going to focus on building a payload tester stub in the C programming language. This will make it easy for us to copy and paste our C-style formatted payload from our build-and-extract tool. Once it’s pasted in the tester stub, just compile and run it and you will be able to see your payload in action. The code for payload tester stub and Makefile can be found in the /utils/ folder of the Secure Ideas Professionally Evil x86_asm GitHub repository.

  • 3 ways to test your API with Python | Opensource.com

    In this tutorial, you'll learn how to unit test code that performs HTTP requests. In other words, you'll see the art of API unit testing in Python.

    Unit tests are meant to test a single unit of behavior. In testing, a well-known rule of thumb is to isolate code that reaches external dependencies.

    For instance, when testing a code that performs HTTP requests, it's recommended to replace the real call with a fake call during test time. This way, you can unit test it without performing a real HTTP request every time you run the test.

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.
