  • Calibre 4.2.0 for Slackware with no external dependencies

    Having Calibre on a computer still requires a USB cable to transfer e-books from the computer to your ereader/phone, but networked alternatives exist. Calibre comes with a content server which can make your e-book library accessible online (on your LAN or on the Internet). Earlier versions of the Calibre content server were too resource-intensive and therefore I have chosen another solution for online access to my books. That’s COPS. which is short for “Calibre OPDS PHP Server“. OPDS (Open Publication Distribution System) Is the protocol through which E-readers can access online libraries. COPS allows me to download new books to read from my Calibre library over the wireless network to both my Kobo e-reader and to FBReader on my phone. No more cables needed!

    [...]

    The challenge was to create a solid Slackware package for Calibre 4. I know, you can simply download pre-built binaries for a generic Linux platform, and SlackBuilds.org even offers a build script to package these binaries for you, but it is much more fun, and very educational, to compile all of it yourself. In addition you’ll get binaries which are native to your Slackware distro instead of having to resort to binaries that were compiled on Ubuntu or Debian and do unpeakable things to your system when you’re not looking.

  • Open Source Open Compute Project Based Switches Growing Fast [Ed: A Microsoft/Facebook openwashing stunt; those two companies steal your data, share it among themselves in the DCs that they then try to paint "Ethical"]

    According to IHS Markit | Technology's Data Center Network Equipment Market Tracker - Q2 2019 report, bare metal switches, that is switches that do no come with a pre-loaded/hard-coded network operating system are a fast growing segment.

  • Karen Sandler Featured on Explained

    Karen highlighted the problems with code that is designed without considering the full set of potential users -- a topic which is very personal for her. Karen has spoken many times about the device which she relies on for her life. Her frustration with the lack of access to the source code -- to a device which regulates her very large heart -- drives her work to pursue software freedom for everyone. It's why she leads Conservancy, an organization dedicated to software freedom and access to source code for all users.

  • Darpa Grand Challenge Finale Reveals Which AI-Managed Radio System Shares Spectrum Best

    The finale was presented live by Imahara, Tilghman, and Ben Hilburn, president of the GNU Radio Foundation. There to witness it were attendees of MWC Los Angeles, a mobile industry convention. Though it was the culmination of three years of competition, the finale allowed the teams’ radio systems to duke it out in real time for the first time. The head-to-head matchup was made possible by DARPA’s efforts in relocating Colosseum, the massive radio frequency emulator at the heart of the competition, to the Los Angeles Convention Center floor just before the event.

  • ACSC warns of Windows malware Emotet spreading in Australia

  • Mozilla: Cloudflare doesn't pay us for any DoH traffic

    Mozilla said today that "no money is being exchanged to route DNS requests to Cloudflare" as part of the DNS-over-HTTPS (DoH) feature that is currently being gradually enabled for Firefox users in the US.

    The browser maker has been coming under heavy criticism lately for its partnership with Cloudflare.

    Many detractors say that by using Cloudflare as the default DoH resolver for Firefox, Mozilla will help centralize a large chunk of DNS traffic on Cloudflare's service.

    Critics of this decision include regular users, but also ISP-backed lobby groups, according to a recent report citing leaked documents.

  • 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.
