  • Your "21st century banking" is sixty years old [Ed: At least COBOL, unlike "modern" and bloated frameworks, remains relevant and still works after all these years]

    There is one software language that controls all your money. A language that pretty much runs, all by itself, the cores of the worldwide financial systems. It cannot be replaced (not without great expense and risk, that is), and cannot be kept either, because the experts that really know it are dying out.

  • Qt Online Installer 4.2.0 beta released
  • Why Coda thinks documents are the internet's next big platform

    The way Shishir Mehrotra sees it, digital documents haven't really changed in 50 years. Since the days of WordStar, Harvard Graphics and VisiCalc, the basic idea of what makes up a document, presentation and spreadsheet haven't really changed.

    Now, thanks to companies like Coda — where Mehrotra is founder and CEO — along with Notion, Quip and others, that's starting to change. These companies are building tools that can do multiple things in a single space, that are designed both for creating and for sharing, and that turn documents from "a piece of paper on a screen" into something much more powerful. And to hear Mehrotra tell it, documents are headed toward a future that looks more like an operating system than a Word file.

    Mehrotra joined the Source Code podcast to talk about Coda's recent announcements, the two-year project to rebuild its core technology, Coda's future as a platform and why he thinks documents can be much more than just documents going forward.

  • Node.js 17 released, not intended for production use • The Register [Ed: Microsoft Tim on how Microsoft is weaponising TypeScript and GitHub to take over Node.js; there's also an outpost in the Linux Foundation that's controlled by a Microsoft mole, "Open"JS]

    Node.js 17 is out, loaded with OpenSSL 3 and other new features, but it is not intended for use in production – and the promotion for Node.js 16 to an LTS release, expected soon, may be more important to most developers.

  • 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.
