  • Creating open data interfaces with ODPi

    Connecting one source of data to another isn't always easy because of different standards, data formats, and APIs to contend with, among the many challenges. One of the groups that is trying to help with the challenge of data interoperability is the Linux Foundation's Open Data Platform initiative (ODPi). At the 2020 Open Source Summit North America virtual event on July 2, ODPi Technical Steering Committee chairperson Mandy Chessell outlined the goals of ODPi and the projects that are part of it. She also described how ODPi is taking an open-source development approach to make data more easily accessible.

    While perhaps not as well-known as other Linux Foundation efforts, ODPi has actually been around since 2015. Chessell explained that ODPi's initial role was to help different vendors using Apache Hadoop to interoperate, since each had its own set of data connectors. As usage and the number of Hadoop vendors has declined in recent years, ODPi defined a broader vision to be an initiative focused on creating open-source data standards to help users understand and make use of data across different platforms.

    [...]

    While code is an important part of ODPi, technology alone isn't the only way to make effective use of data. Chessell noted that as organizations try to become more data-driven, they face cultural, organizational, and technology problems. "For many organizations they operate as a sort of hierarchy that creates silos between each of the different IT systems, and to make use of data you have to sort of break down those silos and allow data and collaboration to flow laterally across the organization," she said.

    The OpenDS4All project is one such non-code effort within ODPi. OpenDS4All is an open data-science project that is focused entirely on education, creating materials that educators and organizations can use to build a data-science curriculum. The project got started in February 2020 based on materials originally created by professors at the University of Pennsylvania.

  • How and why I (attempt to) use Links as main browser

    Many browsers today are gigantic resource hogs, which are basically VMs for various web applications. On the other hand, Links is a HTML browser. It is not able to do everything. It allows me to avoid most distractions and control the content-experience. The goal of this exercise is not to force anyone to use this browser, but just to be watchful and conscious of their hypertext based internet usage (one might use gopher, and this phlog is available there, but probability tells me that a person reading this reads this from hypertext source and I am sure they are lovely).

  • Inside a Collaborative Text Editor

    Collaborative editors are defined by the size and speed of their updates. On a website you might submit a form, but in a collaborative editor you can send a single character or key press.

    Those tiny edits are shared quickly so you feel connected to your collaborators and can anticipate their actions. This experience is described as real-time editing.

    Inside your editor, however, the frequent edits form a hotbed of conflicting updates. Solving or avoiding these conflicts is the real challenge of a collaborative text editor.

  • Why you shouldn’t write your content in Uppercase, instead use CSS.

    First, a caveat, if something is meant to be uppercase, like an acronym, that is okay to write as uppercase, e.g CSS. If your text makes sense semantically in uppercase then it’s not a problem. (Note: HTML has an abbreviation element you should totally use)

    With that in mind, if your content is uppercased, only for design or styling purposes, then it should always be done with CSS. The way that you accomplish this is with the text-transform CSS property.

  • 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.
