  • OpenSnitch Is a Host-Based Firewall for Linux Desktops

    Simone Margaritelli, the VP of Research at Zimperium, has created a Linux port of Little Snitch, a wildly popular macOS firewall application.

    Named OpenSnitch, the Linux port works on the same principles of the macOS version, being a host-based firewall that notifies users when local apps are attempting to initiate new outgoing network connections.

    Similar to Little Snitch's normal modus operandi, when this happens, OpenSnitch will display a popup, asking the user for instructions on how to deal with this new process.

    All user decisions are saved as rules in local JSON files. Users can edit these rules later to fine-tune the firewall or import/export rules from/to other systems.

  • You Can Now Run Progressive Web Apps as Native Chrome OS Apps on Your Chromebook

    Google's François Beaufort recently informed the Chrome OS community about the fact that it's now possible to run progressive Web Apps like native apps in Chrome OS on their Chromebooks.

    Live in the Chrome Canary experimental channel for Chrome OS, the new feature promises to let you run progressive Web Apps just like you would run native Chrome OS apps on your Chromebook. The apps will work offline in their own custom window.

  • More GNOME Performance Improvements Are On The Way

    While it unfortunately didn't happen in time for last month's GNOME 3.28 release, there are more performance improvements en route.

    Several performance fixes are inbound on top of an important performance fix covered at the end of March where Clutter's text rendering code was causing frequent spikes in GNOME Shell's frame-time.

  • Plymouth Adds Device Rotation Support

    Commits these days to Plymouth are fairly rare with this Red Hat developed project seeing its first commits of 2018 yesterday.

    Plymouth doesn't seem commits too often since this Linux graphical boot system is largely in great shape, relies upon the stable DRM/KMS kennel APIs, and has largely hit feature completion for a simple graphical boot screen that is far better than the days of RHGB or alternatives. But a fair amount of new code did land yesterday in Plymouth for now supporting device rotation.

  • 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.
