  • Excellent Free Tutorials and Resources to Learn J

    The J programming language, developed in the early 1990s by Kenneth E. Iverson and Roger Hui, is an array programming language based primarily on APL (also by Iverson). It’s available on a wide variety of computers and operating systems. J is distinguished by its simple and consistent rules, a large set of built-in capabilities, powerful facilities for defining new operations, and a general and systematic treatment of arrays.

    The J system provides: an engine for executing J; various front ends that provide user interfaces to the J engine; a library, written in J, that provides an IDE (interactive development environment), numerous tools, utilities, demos, tutorials; and online documentation.

    J is a very terse array programming language, and is most suited to mathematical and statistical programming, especially when performing operations on matrices. It has also been used in extreme programming and network performance analysis.

    J supports function-level programming via its tacit programming features.

    J is free and open-source software under the GNU General Public License version 3.

  • Stephen Kelly: Location, Location, Location

    As of a few days ago, a new feature in clang-query allows introspecting the source locations for a given clang AST node. The feature is also available for experimentation in Compiler Explorer. I previously delivered a talk at EuroLLVM 2019 and blogged in 2018 about this feature and others to assist in discovery of AST matchers and source locations. This is a major step in getting the Tooling API discovery features upstream into LLVM/Clang.

  • A theory of how developers seek information

    Researchers have been developing a theory, Information Foraging Theory (IFT), of how people seek information, whether it be on the web, in a filing cabinet, or even in source code. It follows a metaphor that stems from animals looking for food in the wild.

  • Some useful regular expressions for programmers

    In my blog post, My programming setup, I stressed how important regular expressions are to my programming activities.

    Regular expressions can look intimidating and outright ugly. However, they should not be underestimated.

    Someone asked for examples of regular expressions that I rely upon. Here a few.

  • 11 Most Common Mistakes That Android Developers Make

    Android is a reliable, customizable, free, and widely used operating system. During the process of developing an android app, we make a lot of mistakes and most of them are common. That’s not the issue that we are making mistakes, but it is always a bigger issue than anything else if we are not learning something by doing a mistake. Learning from mistakes should be in our attitude as an android app developer.

    Also, It is advisable by experts that we should not make the same mistake repeatedly. To doing so, we have to identify that mistake and after learning from it, we should try our best to not make that mistake again. That approach will be an overall development approach for ourselves. The first step is the identification that what we are doing wrong. In this article, we will know about the Top 11 most common mistakes that android developers make.

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.
