  • File Management with AWS S3, Python, and Flask

    One of the key driving factors to technology growth is data. Data has become more important and crucial in the tools being built as technology advances. It has become the driving factor to technology growth, how to collect, store, secure, and distribute data.

    This data growth has led to an increase in the utilization of cloud architecture to store and manage data while minimizing the hassle required to maintain consistency and accuracy. As consumers of technology, we are generating and consuming data and this has necessitated the requirement of elaborate systems to help us manage the data.

    The cloud architecture gives us the ability to upload and download files from multiple devices as long as we are connected to the internet. And that is part of what AWS helps us achieve through S3 buckets.

  • Node.js VS Python: Which is Better?

    Both Node.js (majorly used as a backend framework ), and Python ( front-end and back-end programming language) are used extensively for programming of a web app. It is vital to select a suitable framework or programming language for web app development because it is the backbone of every web app.

    Node.js and Python are extensively used for this purpose. When you talk about Node.js or python,you are actually comparing JavaScript with Python. This is because Node.js is actually a framework built on Google Chrome’s JavaScript.

    Both of them are among the top programming languages according to the TOIBE index.

    Here is the list with May 2018 and May 2019 rankings.

  • How to edit a qcow2 file from C

    Suppose you want to edit or read or write the data inside a qcow2 file? One way is to use libguestfs, and that’s the recommended way if you need to mount a filesystem inside the file.

    But for accessing the data blocks alone, you can now use the libnbd API and qemu-nbd together and this has a couple of advantages: It’s faster and you can open snapshots (which libguestfs cannot do).

    We start by creating a libnbd handle and connecting it to a qemu-nbd instance. The qemu-nbd instance is linked with qemu’s internal drivers that know how to read and write qcow2.

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.
