  • Read and write files with Groovy | Opensource.com

    Two common tasks that new programmers need to learn are how to read from and write to files stored on a computer. Some examples are when data and configuration files created in one application need to be read by another application, or when a third application needs to write info, warnings, and errors to a log file or to save its results for someone else to use.

  • A practical guide to using the git stash command

    Version control is an inseparable part of software developers' daily lives. It's hard to imagine any team developing software without using a version control tool. It's equally difficult to envision any developer who hasn't worked with (or at least heard of) Git. In the 2018 Stackoverflow Developer Survey, 87.2% of the 74,298 participants use Git for version control.

    Linus Torvalds created git in 2005 for developing the Linux kernel. This article walks through the git stash command and explores some useful options for stashing changes. It assumes you have basic familiarity with Git concepts and a good understanding of the working tree, staging area, and associated commands.

  • Why an Open Source GitOps Model Is the Future of DevOps

    At its most basic level, GitOps is a development approach that uses a code version control system, often Git, as the basis for defining and controlling a DevOps workflow and synchronization across systems.

  • GCC 10.3 Release Candidate Arrives For Testing - Phoronix

    While GCC 11 is seeing its first stable release in the form of GCC 11.1 in just a few short weeks, GCC 10.3 is imminent as the latest point release for those on the current GCC 10 stable series.

    GCC 10.3 is a bug-fix release to last year's GCC 10 feature release. GCC 10.3 delivers on a half-year worth of bug fixes to this free software compiler. The GCC point releases tend to be mostly mundane but there are some back-ports worth mentioning like the AMD Zen 3 (znver3) tuning work and other hardware-specific target work but for the most part is largely just genuine compiler bug/regression fixes.

  • This popular code library is causing problems for hundreds of thousands of devs

    A license incompatibility in an extensively used open source library has led to breaking the popular web development framework Ruby on Rails (RoR).

    A developer pointed out his GPLv2 licensed code was being improperly used inside a MIT licensed Ruby library called mimemagic. The issue was quickly sorted by re-releasing mimemagic as GPLv2. To prevent further misuse mimemagic’s developer also yanked the older MIT licensed releases of the library.

  • Some opinionated thoughts on SQL databases

    These opinions are derived from years of using and/or running SQL and other databases primarily as backends for web apps or web APIs. My experience is largely with these kinds of applications, which tend to have relatively predictable data access patterns, and care about low latency, high throughput, and some degree of high availability. I acknowledge that this is not the only purpose that SQL engines are used for, but it’s the one I have experience with and it’s a very common one these days.

  • How I Beat the Berlin Rental Market With a Python Script

    I was able to do so because I was keenly aware of the specific characteristics of the neighborhood, because the house had changed price twice already (-7% first, and another -6% after that) and was unlikely to change the price again, and because it was very likely to be rented soon. I knew all of this thanks to a couple of predictive models and a few weekends of scraping real estate data.

    This is how I did it.

  • Turing Award Goes to Creators of Computer Programming Building Blocks

                     

                       

    On Wednesday, the Association for Computing Machinery, the world’s largest society of computing professionals, said Dr. Aho and Dr. Ullman would receive this year’s Turing Award for their work on the fundamental concepts that underpin computer programming languages. Given since 1966 and often called the Nobel Prize of computing, the Turing Award comes with a $1 million prize, which the two academics and longtime friends will split.

                       

    Dr. Aho and Dr. Ullman helped refine one of the key components of a computer: the “compiler” that takes in software programs written by humans and turns them into something computers can understand.

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.
