  • How to Be a Tech-Savvy

    Learn how to write a program:
    You cannot make anything new in the computer world without programming skills. You can create windows, apps, websites, a desktop application using programming languages. Some programming languages that you can learn in your beginning level of becoming tech-savvy is Java, C, C++, Html, CSS, JAVASCRIPT, PHP, PYTHON. You can enhance your programming skills by sitting home by taking online tutorials.

    Use a Linux or Unix Operating System:
    If you want to be a tech- savvy I recommend using Unix operating system because a techy person mostly uses the Unix operating system in the world. Unix operating system is open source anyone can use it, and you can view its code too. So, it will help in enhancing your programming skills and learning about technical skills.

  • JDK 12: The new features in Java 12

    The production release of Java Development Kit 12, based on Java SE (Standard Edition) 12, is now available. JDK 12 builds are available from Oracle for Linux, Windows, and MacOS. 

    [...]

    Open source builds are provided under the GNU General Public License v2, with Classpath Exception. Commercial builds of JDK 12 from Oracle can be found on the Oracle Technology network under a non-open source license.

  • Python dictionary "addition" and "subtraction"

    A proposal to add a new dictionary operator for Python has spawned a PEP and two large threads on the python-ideas mailing list. To a certain extent, it is starting to look a bit like the "PEP 572 mess"; there are plenty of opinions on whether the feature should be implemented and how it should be spelled, for example. As yet, there has been no formal decision made on how the new steering council will be handling PEP pronouncements, though a review of open PEPs is the council's "highest priority". This PEP will presumably be added into the process; it is likely too late to be included in Python 3.8 even if it were accepted soon, so there is plenty of time to figure it all out before 3.9 is released sometime in 2021.

  • Debugging and Profiling Python Scripts [Tutorial]

    Debugging and profiling play an important role in Python development. The debugger helps programmers to analyze the complete code. The debugger sets the breakpoints whereas the profilers run our code and give us the details of the execution time. The profilers will identify the bottlenecks in your programs. In this tutorial, we’ll learn about the pdb  Python debugger, cProfile module, and timeit module to time the execution of Python code.

    This tutorial is an excerpt from a book written by Ganesh Sanjiv Naik titled Mastering Python Scripting for System Administrators. This book will show you how to leverage Python for tasks ranging from text processing, network administration, building GUI, web-scraping as well as database administration including data analytics & reporting.

  • 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.
