  • HackUp is a Desktop Hacker News Client for Linux

    Avid readers of social news sharing site Hacker News might be interested in a new app recently added to Flathub.

    Called HackUp, it is a Hacker News desktop client written in Vala. It lets you browse and read Hacker News submissions without needing to open a web browser (which for a legendary procrastinator like me, is a good thing).

  • Why use Chef for automation and orchestration

    Chef has been a leading open source tool for automating the provisioning and configuration of servers for the better part of a decade. In recent years the company added InSpec and Habitat to the portfolio, open source projects that automate policy compliance testing and the deployment and configuration of applications, respectively. The company’s flagship commercial offering, Chef Automate, brings all of these pieces together.

  • Monday Markdown

    I’ve spent the first portion of the coding period focused on improving the documentation browser for GNOME Javascript. In 2015/16 ptomato began porting GIR sources (the source of most GJS documentation) to [DevDocs.io], an open-source documentation browser, using g-ir-doc-tool in gobject-introspection. He did excellent work and produced a functioning product that now lives at [devdocs.baznga.org]. My goals were to take the current product and incorporate GNOME theming, fix issues with incorrect documentation, rebase the project on upstream, and reorient some of the project’s features to better serve an object oriented and GNOME model.

  • Refactor: Backend and UI

    Fractal is currently structured into two parts: The API part (fractal-matrix-api) and GTK part (fractal-gtk). The first one mostly just does the https calls to the Matrix server, the GTK part does everything else. This post will not talk about the API part since that will remain more or less the same (at least for now).

  • Open source board lets you analyze SPI connections on a USB-connected laptop

    Excamera Labs has launched an open source, $27 and up “SPIDriver” board on Crowd Supply for analyzing and testing SPI-connected displays, sensors, flash, and other components on a laptop or via a built-in color LCD display.

    Monitoring SPI devices such as LCD panels, LED arrays, sensors, and SPI flash may not be quite as gnarly as managing I2C gizmos, but either of these short-distance, serial data transfer protocols can be a hassle. While Arduino boards provide libraries for SPI monitoring, there’s still a lot of guesswork involved due to lack of real-time feedback about the SPI bus state.

  • Cooperative Learning

    I’ve got some under-utilised KVM servers that I could use to provide test VMs for network software, my original idea was to use those for members of my local LUG. But that doesn’t scale well. If a larger group people are to be involved they would have to run their own virtual machines, use physical hardware, or use trial accounts from VM companies.

    The general idea would be for two broad categories of sessions, ones where an expert provides a training session (assigning tasks to students and providing suggestions when they get stuck) and ones where the coordinator has no particular expertise and everyone just learns together (like “let’s all download a random BSD Unix and see how it compares to Linux”).

    [...]

    There is a Wikipedia page about Cooperative Learning. While that’s interesting I don’t think it has much relevance on what I’m trying to do. The Wikipedia article has some good information on the benefits of cooperative education and situations where it doesn’t work well. My idea is to have a self-selecting people who choose it because of their own personal goals in terms of fun and learning. So it doesn’t have to work for everyone, just for enough people to have a good group.

  • Chinese search giant Baidu creates an open-source A.I. for detecting cancer

    “We hope this open-sourced algorithm can serve as a high-quality baseline for future research in this area,” Li said. “The algorithm is only evaluated on a limited number of public datasets at this stage. However, the algorithm needs to be further assessed using much more clinically relevant data to prove it still maintains higher accuracy than experienced pathologists. Our team will continue improving the algorithm and collaborating with researchers with whom we can share new datasets.”

  • Fynd organizes Hackxagon Open Source Challenge for its Engineers

    As an initiative to give back to the open source community, Fynd, the unique fashion e-commerce portal had launched gofynd.io, a few months ago. This project enabled the engineers of the fashion e-commerce portal to learn new technologies, improve the core infrastructure and enhance the Fynd platform.

  • Netfilter Workshop 2018 Berlin summary

    Lots of interesting talks happened, mostly surrounding nftables and how to move forward from the iptables legacy world to the new, modern nft framework.

    In a nutshell, the Netfilter project, the FLOSS community driven project, has agreed to consider iptables as a legacy tool. This confidence comes from the maturity of the nftables framework, which is fairly fully-compliant with the old iptables API, including extensions (matches and targets).

  • Introducing PyInstaller

    If you're used to working with a compiled language, the notion that you would need to have a programming language around, not just for development but also for running an application, seems a bit weird. Just because a program was written in C doesn't mean you need a C compiler in order to run it, right?

    But of course, interpreted and byte-compiled languages do require the original language, or a version of it, in order to run. True, Java programs are compiled, but they're compiled into bytecodes then executed by the JVM. Similarly, .NET programs cannot run unless the CLR is present.

    Even so, many of the students in my Python courses are surprised to discover that if you want to run a Python program, you need to have the Python language installed. If you're running Linux, this isn't a problem. Python has come with every distribution I've used since 1995. Sometimes the Python version isn't as modern as I'd like, but the notion of "this computer can't run Python programs" isn't something I've had to deal with very often.

  • Demoting multi-factor authentication

    Authentication was done via a Java applet, as there needs to be a verifiably(?)-secure way to ensure the certificate was properly checked at the client without transfering it over the network. Good thing!

    [...]

    Anyway I accepted, as losing so much time to grade is just too much. And... Yes, many people will be happy. Partly, I'm releieved by this (I have managed to hate Java for over 20 years). I am just saddened by the fact we have lost an almost-decent-enough electronic signature implementation and fallen back to just a user-password scheme. There are many ways to do crypto verification on the client side nowadays; I know JavaScript is sandboxed and cannot escape to touch my filesystem, but... It is amazing we are losing this simple and proven use case.

  • 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.
