  • You should know the comparison between Java 8 & Java 9

    Java language is based on an Object-Oriented Programming algorithm. Oracle is currently maintaining Java. Being licensed under General Public License GNU, Java 8 was released on 14th January 2014 whereas Java 9 on 27th July 2017. The latest version is Java 13, which was released on 17th September 2019.

    If you’re applying for a job position as a Java Developer, you might want to read some Java 8 interview questions and also clarify differences between Java 8 and Java 9. The 8th version of Java included important updates. The basic purpose of Java 8 was to provide enhancements, bug fixes and improve the efficiency of coding compared to its predecessor. Java 9 included updates to enhance industry-wide development through a new platform module system.

    Java 9’s accessibility and improved modularity help developers to easily assemble and maintain sophisticated applications. It also helps in making Java scale down on smaller devices while improving security and performance.

  • LLVM Plumbs Support For Intel Golden Cove's New SERIALIZE Instruction

    Yesterday we noted Intel's programming reference manual being updated with new Golden Cove instructions for Sapphire Rapids and Alder Lake and with that Intel's open-source developers have begun pushing their changes to the compilers. The latest updates add TSXLDTRK, a new HYBRID bit for Core+Atom hybrd CPUs, and a new SERIALIZE instruction. After GCC was receiving the patch attention yesterday, LLVM is getting its attention today.

  • Reuven Lerner: Reminder: My free “Python for non-programmers” course continues tomorrow!

    If you’ve never programmed a computer before — or if you tried, and found it frustrating and difficult — then you’re welcome to join my “Python for non-programmers” course, which takes place on Thursdays at 10 a.m. Eastern.

    The class is 100% free of charge, and open to anyone who wants. Just register at https://PythonForNonProgrammers.com/. Registering gets you weekly reminders, recordings of previous sessions, and invites to the private forum, where you can chat about the lessons with other students.

  • Django changes its governance

    The Django web framework has come a long way since it was first released as open source in 2005. It started with a benevolent dictator for life (BDFL) governance model, like the language it is implemented in, Python, but switched to a different model in 2014. When Python switched away from the BDFL model in 2018, it followed Django's lead to some extent. But now Django is changing yet again, moving from governance based around a "core team" to one that is more inclusive and better reflects the way the project is operating now.

    Django actually started out with co-BDFLs; Adrian Holovaty and Jacob Kaplan-Moss filled that role until they retired in early 2014, which motivated the change to the core-team model. By 2018, some problems with that new model were being felt, so James Bennett spearheaded an effort to change it, which resulted in Django enhancement proposal (DEP) 10 ("New governance for the Django project")—adopted on March 12. Perhaps unsurprisingly, some of the problems identified for Django are sometimes heard in Python circles as well; the changes for Django could be a harbinger of Python's governance down the road.

  • 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.
