  • China's Alternative To GSoC Is Seeing Some Interesting Summer Open-Source Projects

    Back in May we wrote about China launching an alternative to Google Summer of Code and Outreachy. This global open-source program hosted by the Institute of Software Chinese Academy of Sciences is running "Summer 2021" for encouraging university-aged students regardless of gender or nationality to get involved in open-source development. 

    The Summer 2021 program pays out roughly $932 to $1865 USD per project depending upon complexity. Open-source community projects can participate as well to receive help if they are under an OSI-approved software license. 

  • GSOC with KStars 02: Community Bonding and First Coding Period

    Of course the task I described in the last post looks and is quite monumental. That is why I laid some of the groundwork for my GSOC beforehand (in the actual German semester breaks). This work continued in the community bonding and first coding period and will therefore be described here.

    But first I want to thank my mentor Jasem Mutlaq for his support, his patience with me and his nerves of steel. My mood levels were somewhat similar to a huge-amplitude sine wave those last weeks.

    Now to the meat…

    I began by studying the existing deep sky object implementation in KStars to identify what structure the new catalogs should have and what the smallest irreducible core of functionality was I could replace to make integration easier. I discovered that the catalogs were a mix of SQL databases and text files, somehow loaded at startup and then appended to some linked list. There was some deduplication implemented but like most DSO code it was oddly catalog specific. Especially the Messier, IC and NGC catalogs were often mentioned in the code. Also the explicit distinction between stars and DSOs made writing general code complicated but I found a consistent set of data fields shared by all catalog objects which all admitted sane defaults. It wasn't bad code or anything like that. Just the product of "organic groth" with many thing I wanted already present in some way but somewhat all over the place. I admit that I studied the code just enough to find out what exactly I had to replace and maybe I could have reused more of the existing code but I've picked this specific path in the multiverse, so let's get on with it. Just a shout out to all who did previous work on the DSO code among whom are, just to name a few, Jason Harris, Rishab Arora, Thomas Kabelmann and Akarsh Simha.

  • digiKam: GSoC 2021 Week 4-5 | Anjani's blog

    Last two weeks was the first time I started planning to build digiKam with Qt6. A major problem was that digiKam used Qt Webengine/Qt Webkit to have support of in-built browser for displaying online documents and webservice authorization steps.

    Qt Webengine/Qt Webkit modules, as of now, are not available in Qt 6.1.2 and will only be stable with release Qt 6.2, expected to arrive in September 2021. It is not trivial to isolate code that dependeds on this module. I thought about some solutions like building with alpha Qt 6.2 release. It failed. Me and my mentors had a long discussion about the solution and Gilles suggested that writing a dummy API for now is a good solution.

  • Update On My Gsoc Project

    I realize it has been a long time since the start of GSoC and I didn’t write any update blogs on the status of my project, I’m currently working on Okular to extend it to have better support for custom image stamps. Right now, Okular doesn’t fully support representing Stamp Annotations, resulting in not being able to render Stamps or not being able to save custom ones so that other viewers are able to render them.

    I’m currently working under the mentorship of Albert Astals Cid, whom I’d like to thank a lot for his continuous support and help. He has been really supportive and made the GSoC period a really fruitful journey so far.

GSoC 2021 KMyMoney - Week 3, 4 and 5

  • GSoC 2021 KMyMoney - Week 3, 4 and 5

    Week 5 was more into replacing the WebPriceQuote usage in KMyMoney and figuring out what APIs are needed in libalkimia.

    I noticed that the online quotes that were in kmymoneyrc weren’t visible in the Online Quotes dialog. I figured out that and used the kmymoney profiles only. As also further pointed by Ralf, the onlinequoteseditor (in libalkimia) is intended to support multiple applications and therefore adds multiple profiles.
    As unit tests were already written in libalkmia I run all the tests to check if something were wrong. All the tests passed successfully.

    I started replacing WebPriceQuote implementation with that of Alkimia one by one. I managed to do so with the help of API documentation and previous KMyMoney 4.8 implementation. I found that some of the implementations were not present in libalkimia

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.
