  • Laravel dynamic SMTP mail configuration :: Aloïs Micard — Tech Blog

    Hello friend…

    It has been a while.

    I have been very busy lately with work, open source and life that I didn’t find the energy to write a blog post. Despite having some good ideas, I wasn’t really in the mood.

    Hopefully, I now have the energy and the subject to make a good blog post: let’s talk about Laravel and emails!

  • Laravel: beware of $touches :: Aloïs Micard — Tech Blog

    I have been using Laravel professionally since almost 1year, and I must say: I’m very impressed with the framework. Everything’s run smoothly, there’s a feature for (almost everything) you can think of, so you (almost) never need to reinvent the wheel.

    This is very advantageous since you only focus on building your product features by features and spend less time working on technical stuff who are less business valuable.

  • OpenGL Machine Learning Runs On Low-End Hardware | Hackaday

    If you’ve looked into GPU-accelerated machine learning projects, you’re certainly familiar with NVIDIA’s CUDA architecture. It also follows that you’ve checked the prices online, and know how expensive it can be to get a high-performance video card that supports this particular brand of parallel programming.

    But what if you could run machine learning tasks on a GPU using nothing more exotic than OpenGL? That’s what [lnstadrum] has been working on for some time now, as it would allow devices as meager as the original Raspberry Pi Zero to run tasks like image classification far faster than they could using their CPU alone. The trick is to break down your computational task into something that can be performed using OpenGL shaders, which are generally meant to push video game graphics.

  • Ruby transition and packaging hints #1 - Adjusting Ruby version in commands | The Ruby Team Pages

    This is the first part of a series of short posts about issues that came up during the Ruby 3.0 transition and how to fix them. Hopefully more team members will join in and add their input.

  • Ruby transition and packaging hints #2 - Gemfile.lock created by bundler/setup with Ruby 2.7 preventing successful test with Ruby 3.0

    In another case the .lock file is created by the tests in gemfiles/. While the first examples could actually be solved by gem2deb removing Gemfile.lock on its own, I’m not quite sure how to handle the last case using packaging tools.

    The interesting part is that we will unlikely be confronted with this issue anytime soon again. It seems very specific to the Ruby 3.0 transition.

  • Python-docx and Raspberry PI: Automating MS Word Reports Creation and Sending

    Reports are vital part in many organizations needing to keep under monitoring some aspects which are core for the business. Automating these reports usually require advanced software, but we can achieve the same goal with python-docx and Raspberry PI

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.
