  • Integration of sandboxed Qt applications

    We have been using various tweaks to make sandboxed Qt apps well integrated into the system. For KDE Plasma integration, we have been allowing access to kdeglobals config file, where we store the most common configuration, like used icon theme, widget style, etc. A similar approach has been used by Gnome, where they need to allow access to DConf, otherwise applications will not be able to read default system configuration. These tweaks have been usually set in the runtimes and applications using these runtimes automatically inherited all the needed permissions during the build. This has some weak spots, because changing permissions in the runtime requires all applications to be rebuild to pick up the changes, or applications not using the runtimes at all had to allow all the access themself and really not everyone knows what everything needs to be enabled.

  • Fedora Firefox heads to updates with PGO/LTO.

    I’ve had lots of fun with GCC performance tuning at Fedora but without much results. When Mozilla switched its official builds to clang I considered that too due to difficulties with GCC PGO/LTO setup and inferior Fedora Firefox builds speed compared to Mozilla official builds.

    That movement woke up GCC fans to parry that threat. Lots of arguments were brought to that ticket about clang insecurity and missing features. More importantly upstream developer Honza Hubicka found and fixed profile data generation bug (beside the others) and Jakub Jelinek worked out a GCC bug which caused Firefox crash at startup.

  • Apple’s Biggest Problem? My Mom

    But the most consequential hit to Apple’s bottom line may be from people who are holding on to their phones for longer. Back in 2015, iPhones were being replaced after roughly two years, on average, according to BayStreet Research, a firm that tracks smartphone sales. That period has jumped to roughly three years, and is expected to grow even 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.
