  • Could Linux help overcome blockchain's usability challenge

    Android, developed on Linux, is the biggest mobile operating system by far, used by 85 percent of users. Given its credentials as an extremely popular open-source and free operating system, Linux could provide the most powerful opportunity to build a bridge between blockchain and the real world.

    Although it’s not widely used as a desktop operating system, Linux has been released for more hardware platforms than any OS in history. The chances are you’re already using it in some format, as Linux is embedded into hardware such as TVs, game consoles, routers, smartwatches, and more.

  • WordPress introduces a new way for bloggers to get paid

    WordPress, one of the internet’s leading purveyors of blog infrastructure and hosting, has taken a step toward making blogging more sustainable by allowing sites to easily accept recurring payments. Think: subscriptions. The tool will be available to anyone with a paid WordPress site and to sites that use the company’s Jetpack toolkit.

  • Digging for license information with FOSSology

    For a number of years FOSSology was distributed and maintained by HP, until it became an LF project in 2015. It is easier for companies to collaborate on software in a project at an organization like the LF, he said, it makes for a safer harbor for competitors to work together—in Germany, at least. He works for Siemens AG, which is a rather large Germany company.

    Breaking up archive files into their constituent files—some of which may need to be unpacked themselves—then scanning the individual source and other files for their licenses is the basic task of FOSSology. It has a powerful license scanner, he said. Its web-based interface can then give an overview of the contents—which licenses apply to various parts of the tree, for example—and allow users to drill down into the file hierarchy to the individual files to see their copyrights and license-relevant text. When looking at the file, FOSSology highlights that license-relevant text and shows a comparison with the reference text of the license it has determined for the file.

    Determining the license that applies to a file is challenging, however. Files have a wide variety of license-relevant text in them, some of which is ambiguous. It depends on the kind of source code you are working with, but the scanner is unable to decide on a license for up to 30% of files it sees, so it is up to a human reviewer to tag the right license. It is then important to also track what reviewers decide on files in the FOSSology database.

    The Software Package Data Exchange (SPDX) format is used to describe various things in a package, including licensing information. FOSSology can both import and export SPDX information, which allows exchanging information between two FOSSology users to share analysis work. FOSSology is one of a few tools that can consume SPDX information; it can be used to review what another party has concluded about the licensing of a code base. In addition, when a package gets updated, the previous analysis can be used as a starting point; the new dependencies and other changes can be incorporated into that rather than starting from scratch.

    [...]

    Huber handed the microphone back to Jaeger to wrap up the presentation. He said that FOSSology participated in the Google Summer of Code (GSoC) for 2019; the project had three GSoC participants working on various projects. FOSSology has been working on integrating with three different open-source projects as well. Software Heritage is a repository of published software, while ClearlyDefined is a repository of metadata about published software. In both cases, FOSSology has plans to interact with them via their REST APIs. The third project is not as well known, he said. Atarashi takes a new approach in scanning for licenses. Instead of using regular expressions and rules, it uses text statistics and information-retrieval techniques.

    Another initiative that the project has undertaken is FOSSology Slides, which is a site for gathering slides that can be used to talk and teach about FOSSology. They are all licensed under CC BY-SA 4.0 (as are the slides [PDF] from the OSS EU talk). They can be used as is, or adapted for other uses; he encouraged anyone to contribute their FOSSology slides as well. One nice outcome of that is that some Japanese FOSSology users translated slides from FOSSology Slides to that language and contributed them back, Jaeger said. Other translations would be welcome for those who want to contribute to the project but are not software developers.

    A FOSSology user in the audience pointed out that the tool is only able to analyze the code it is given, so package dependencies have to be figured out separately. Jaeger agreed, noting that FOSSology is focused on understanding the licenses in the code it is given; there are other tools that can help figure out what the dependencies are and there are no plans to add that to FOSSology. He suggested the OSS Review Toolkit (ORT) as one possibility.

  • 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.
