Jussi Pakkanen: Mixing Rust into an existing C shared library using Meson

Many people are interested in adding Rust to their existing projects for additional safety. For example it would be convenient to use Rust for individual high-risk things like string parsing while leaving the other bits as they are. For shared libraries you'd need to be able to do this while preserving the external plain C API and ABI. Most Rust compilation is done with Cargo, but it is not particularly suited to this task due to two things.

[...]

As adding numbers is highly dangerous, we want to implement the adder_add function in Rust and leave the other functions untouched. The implementation in all its simplicity is the following...

20 Useful Grep Command Examples in Linux

Grep is a command-line utility widely used in Linux/Unix that uses in searching data sets of specific files for lines that match a regular expression of plain texts. Grep stands for Global Regular Expression Print. It was originally named by Ken Thompson who was also the original author. He named it so because in ed the command g/re/p has the same effect as grep. In this guide we will cover 20 useful grep command examples.

Bash if-else statements

In your day-to-day life, many things are associated with conditions. For example, when we decide, we first analyze its conditions, outcomes and finalize the decision. Conditional statements in any programming language shadow the same way, and they are core to every language. These statements are used to manage code execution flow and perform tasks based on true and false conditions.

Difference between CPython, Jython, IronPython, PyPy, and Cython – Linux Hint

Computer Science is one of the hottest fields out there right now, and it keeps on growing and expanding further. It has tremendously evolved from what it used to be in the early days and now is being used for content that is changing the lives of millions of people. Such has been its advancement that has allowed concepts like artificial intelligence, deep learning, and so many others, which once looked impossible to come into existence.

One particular element of computer science that has seen a large evolution is the programming language section, which is an integral part of machines and comprises instructions that allow the machines to perform different tasks. Python is one high-level programming language that has immensely grown and is being used in multiple sectors of the industry.

However, Python itself is vast and can be implemented in several different flavors, which shall also be the topic of our discussion in this article, and where we will be looking at the different implementations that currently exist of Python.

How to Create Django Views? – Linux Hint

Different types of data of Django application, such as HTML content, XML data, JSON data, image, 404 error, etc. are transferred to the template through Django view. Each view is created for a specific purpose and associated with a particular template. The data of the view can be generated from the user through HTML form or from the database or business logic. Django views can be created using a method of python class or python function. The class-based views contain many functionalities compared to function-based views. For this, most of the Django applications use class-based views to represent the data of the Django application. The ways of creating the function-based view and class-based view have been explained in this tutorial.

A blog post about blog posts

There are lot's of good reasons for using the system perl, some of which include that the distribution packagers spend much time bundling and patching them, the security advantage of system perl packages being digitally signed (plenv and perlbrew don't have any such mechanisms), or using mod_perl that comes with the distribution.

Folks may also be using perl for utility scripts in a perl averse company.

Disparaging comments about which perl interpreter people use and how it's installed don't persuade, inform, or encourage people to do more with perl, nor do they respect the different circumstances that other people may be working under.

Vue Computed Deep Structures – Linux Hint

When it comes to the computation of nested or deep data types like arrays or objects, Vue.js or any other programming language does not automatically detect the hierarchical change in the data. However, we all know that Vue.js provides the watch and computed properties to perform some change variables. But when it comes to nested data changes, Vue.js does not detect that. This post will learn to perform some changes by watching the nested data of arrays or objects.

Before learning about watching nested data in Vue.js, let’s first understand how the watch property works?

Dirk Eddelbuettel: RcppArmadillo 0.10.2.2.0 on CRAN: New Upstream Patch Release

Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 841 other packages on CRAN.

This release brings us a second update within the Armadillo 10.2 series, one month after the initial release. Upstream work has commenced at a 10.3 series with first pre-releases which we are currently testing. If possible, CRAN release will continue to be at least one month apart (such as this time) but we continue to make interim releases available on the Rcpp drat repo repo.

Troubleshoot WiFi problems with Go and a Raspberry Pi

Last summer, my wife and I sold everything we owned and moved with our two dogs to Hawaii. It's been everything we thought it would be: beautiful sun, warm sand, cool surf—you name it. We've also run into some things we didn't expect: WiFi problems.

Now, that's not a Hawaii problem. It's limited to the apartment we are renting. We are living in a single-room studio apartment attached to our landlord's apartment. Part of the rent includes free internet! YAY! However, said internet is provided by the WiFi router in the landlord's apartment. BOO!

Boost Your Programming Skills by Reading Git's Code

Each of these methods will appeal to different people, and each one has elements that will definitely make you a better programmer. If you are an intermediate or advanced coder, it is almost certain that you've tried each of these methods at least once.

However, there is another method that the vast majority of developers overlook, which is a shame in my opinion because it has so much to offer. This method is to learn by reading, analyzing, and understanding existing, high-quality codebases!

We are lucky to live in a time where good code is often accessible for free via high-quality, free-and-open-source (FOSS) projects.

Java 16 Goes GA on March 16 Includes 17 Enhancements -- ADTmag

The general availability (GA) release of the Java 16 Platform (Java SE 16) and the Oracle Java Development Kit (Oracle JDK) is set for March 16.
