Your Hot New Stuff Here

KNewStuff, our Framework designed to make it as easy as possible for people to Get Hot New Stuff for whatever app they're running, and for the people who make those apps to add that same functionality to the apps, has for some time suggested that the KDE Store has the ability to accept uploading of content directly from the application. Unfortunately, due to the way this was originally built (which was essentially built around the idea that People Are Nice) turned out to be a fairly effective vector for spam and malicious content.

The result of this is that for several years, while KNewStuff has had an implementation of the OCS Content Create functionality, there is no serverside implementation which supports it as it stands. Which is a shame, especially when, while we may not be able to do it through the API because people are, apparently, sometimes Not Nice, what we can do instead is make it easier for people who are nice to learn how to add their own stuff to those listings.

[...]

While working on this innocent seeming bit of stuff, i ran into few little things that needed to be done first. Of course, i could have hacked this and just Made It Work, but also that is not what we do in KDE.

The first, probably smallest thing is that this inherently shows up in our mobile apps, because it's now a part of both Page and Dialog now. Not that there's a problem with people finding their way to the store and uploading things there, but if we catch just a couple of people who would have otherwise not uploaded their stuff for the rest of the world to see, well, i'll chalk that down as a win Big Grin

As for more technical things, the way in which one would get a list of the providers known to a KNewStuffCore::Engine was previously all manner of awkward, and really does not fit into how a modern Qt application works (that is, you'd call one function to get some string IDs, then you'd call another function to get each provider, and there was no good way to keep track of what might happen if another got added late, and so on). So, we now have a little model, KNSCore::ProvidersModel, which handles this, and just gives you a list of all the Providers known to an Engine, with a bunch of roles that lets you read all the information you need.

  • 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.
