  • Facebook AccountKit with Qt/C++ on Android

    Facebook’s AccountKit is an authentication service that can use your email or phone number to login to your services, it doesn’t require that the user has a Facebook account, just a valid email or phone.

    The cool thing about it is that it sends SMS for free, and although sending SMSs is cheap being free of charge is something you might want to look when creating a new App, in fact here in Brazil some big Apps do make use of it.

    So long story short story I wanted to add this to my Qt Android App.

  • NeuroFedora updated: 2019 week 2

    We had our first meeting of the year. The full logs from our meeting are available here on the Fedora mote application. I have pasted the minutes of the meeting at the end for your convenience.

    The meeting was broadly for the team to come together and discuss a few things. We checked on the status of current tasks, and discussed our future steps. We've got to work on our documentation, for example. There's a lot to do, and a lot of cool new things to learn---in science, computing, and community development. If you'd like to get involved, please get in touch.

  • Alibaba Snaps Up data Artisans for €90 million: Open Sources “Blink”

    Streaming analytics market projected to reach $47 billion by 2025

    Alibaba has bought Berlin-based startup Data Artisans for a reported €90 million (£80 million) in a deal that will see the $39 billion (by 2017-2018 revenues) Chinese juggernaut take its in-house Apache Flink code developments open source.

    Data Artisans was founded in 2014 by the creators of data stream processing engine Flink. It won Intel Capital funding for its Series A round in 2016 and appears to have also had Alibaba backing in an unreported Series B.

  • LCZero Chess Engine Performance With OpenCL vs. CUDA + cuDNN vs. FP16 With Tensor Cores

    A Phoronix reader pointed out LCZero (Leela Chess Zero) a few days ago as an interesting chess engine powered by neural networks and supports BLAS, OpenCL, and NVIDIA CUDA+cuDNN back-ends. Particularly with the FP16 cuDNN support, this chess engine can be super fast on NVIDIA's latest Turing GPUs with tensor cores. 

    With LCZero's build process being sane for its different back-ends and the program turning out to be benchmark-friendly and meeting my requirements, it's now available via the Phoronix Test Suite with a simple phoronix-test-suite benchmark lczero (granted, the back-end support may obviously vary depending upon your hardware/driver support) and more details over on OpenBenchmarking.org.

  • 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.
