  • new, switch and assert keywords in Java

    When we create a class in Java and decide to use this class, we need to make an object of this class and using the object of the aforementioned class we control and use the components of the class.

    An object of a class works like the handle of a motorbike. If you need to control the bike you need to hold the handle of this bike. I believe you have understood why we need to create an object.

    You must be thinking if the object is so important, we need to know how to create an object of a class. We create an object of a class by using the ‘new’ keyword. The ‘new‘ keyword gives instructions to the processor to holds the memory in the system to store the object of this class.

  • The Rust Programming Language Blog: Reducing support for 32-bit Apple targets

    The Rust team regrets to announce that Rust 1.41.0 (to be released on January 30th, 2020) will be the last release with the current level of support for 32-bit Apple targets. Starting from Rust 1.42.0, those targets will be demoted to Tier 3.

    The decision was made on RFC 2837, and was accepted by the compiler and release teams. This post explains what the change means, why we did it, and how your project is affected.

  • Ruby 2.7 Now Available

    As with past few releases, the last major release of the Ruby programming language before 3.0 was released around Christmas. Ruby 2.7.0 comes with new features and performance improvements “larger in scale than previous releases”, as the team behind Ruby puts it.

    Among the newly introduced changes are pattern matching, REPL improvement, compaction GC and the separation of positional and keyword arguments. One of the most highlighted additions is Pattern matching, a widely used feature in functional programming languages. Introduced as an experimental feature, it can traverse a given object and assign its value if it matches a pattern.

  • PyOpenGL 3.1.5 is Out

    I've pushed out the PyOpenGL 3.1.5 release. It has some (relatively minor) fixes for wgl and egl operations, and one for what looks like a change in numpy scalar handling in the latest numpy. Available on PyPI now.

  • How to Automatically Send Text Messages on Android Using Python

    The process of sending text messages can be automated easily using the Python Programming Language by writing a few lines of code. Python provides modules like PYAIRMORE that can be used to send text messages from android device. This module has many functions but we will discuss about sending messages. Sending messages using PYAIRMORE is same as sending messages from your android. The only difference is we perform this task by writing a script and by means of scripting, you can automate a lot of stuff. To perform this task, you must have an android device with AirMore app installed on it.

  • DjangoCon Europe 2020 Announcement

    Your location prior to the event is not significant. We can do all things that need to be done in Porto ourselves. The only important thing is that you have the energy and free time to help organize a wonderful DjangoCon Europe. The official language of all these prior activities will be English, as well as the conference itself.

  • 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.
