  • Wireshark 3.4.10

    Wireshark is a network packet analyzer. A network packet analyzer will try to capture network packets and tries to display that packet data as detailed as possible. You could think of a network packet analyzer as a measuring device used to examine what's going on inside a network cable, just like a voltmeter is used by an electrician to examine what's going on inside an electric cable (but at a higher level, of course). In the past, such tools were either very expensive, proprietary, or both. However, with the advent of Wireshark, all that has changed. Wireshark is perhaps one of the best open source packet analyzers available today.

  • Pantheon Kicks off Program to Give Back to Open Source Communities with Second Annual Gift of Open Source

    The program’s ultimate goal is to provide resources and mentorship to engage and energize first-time contributors to give back to open source. Opportunities are broad, spanning code- or non-code-based contributions to Drupal or WordPress projects, Pantheon repositories, GitHub pull requests or adjacent projects. For each contribution up to 500 contributions made, Pantheon will donate $20 to the Drupal Association and WordPress Foundation, for a total potential of $5,000 to each organization to support their efforts.

  • In the '80s, spaceflight sim Elite was nothing short of magic. The annotated source code shows how it was done

    Just a fortnight under 40 years ago, the BBC Micro was released. Although it was never primarily a games machine – it was too expensive, for a start – nonetheless one of its defining programs was a video game: Elite.

    Its source was released a few years ago, but your correspondent just discovered a lavishly described and documented online edition if you want to see exactly how it was done. The annotations were written by Mark Moxon, a web dev and journalist who among many other things was once editor of Acorn User magazine.

    Elite was famous for several things, including its very considerable difficulty and amazing – for 1984 – wireframe 3D graphics with hidden-line removal. This was displayed on a screen which combined high-resolution and multi-colour graphics in a way the BBC's hardware couldn't natively do: the game changed screen modes from Mode 4 (medium-resolution monochrome) to Mode 5 (low-resolution four-colour) two-thirds of the way though generating each screen. At 50Hz, on a 2MHz 6502.

  • Friday FOSS fest: Franz, RamBox, Pidgin and more • The Register

    Most modern chat systems are entirely proprietary: proprietary clients, talking proprietary protocols to proprietary servers. There's no need for this: there are free open standards for one-to-one and one-to-many comms for precisely this sort of system, and some venerable clients are still a lot more capable than you might remember.

    But as it is today, if you need to be on more than one chat system at once, the official way is to install their client app, meaning multiple clients – or at best, multiple tabs open in your web browsers. Most of these "clients" are JavaScript web apps anyway, running inside Electron – an embedded Chromium-based single-site browser. Which is fine, but Chrome is famously memory-hungry.

    There is a brute-force way round this: have one app that embeds lots of separate Electron instances in tabs. There are a few of these around – first came RamBox, followed by Franz. Both use the "freemium" model: there's a completely functional free client, plus subscriptions for extra features. If you prefer to avoid such things, both services have no-cost forks: Ferdi from Franz and Hamsket from RamBox. A newer rival still is Station.

  • COP26: Why a data commons is needed to secure net zero commitments

    We don’t have time for everyone to build their own financial and non-financial data aggregation platforms in order to facilitate capital allocation. Open-source collaboration could be the answer.

    At COP26 in Glasgow, I was invited to be the master of ceremonies for an event hosted by Federated Hermes’ Daniel Godfrey, and delivered by OS-Climate.

    In a giant inflatable igloo on a carpark next to the main venue, Truman Semans, the founder of OS-Climate, explained his vision: a data commons in the cloud – based on open-source community principles – that will connect investors, investees and entire ecosystems to the data and needed to facilitate capital allocation to green projects. This is what the planet and its inhabitants urgently need.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
