Introduction

Content sharing in the web world is primarily provided by WordPress, an open-source Content Management System (CMS from now on) written in PHP language. For this reason, it is very important to master the software installation. So, the aid of IT automation and its tools (like Ansible) is really important, because in this way you can easily install and manage the software.

One of these softwares is Ansible, which is an IT automation engine that automates configuration deployments, cloud provisioning, application deployment, and other IT needs. It offers a simple framework

There are two methods for using devices on FPGA for PYNQ: the integrated microprocessor (PS side) and the programmable logic (PL side). In order to maximize the use of the FPGA, this article shows how you can use the programmable logic for common devices such as SPI, I2C and UART.

We have used this flow also for SMART-IO Project. If you have lost the article about SMART-IO, follow this link!

You can find every design in this article as Github project in the MakarenaLabs Github company.

Introduction

In this article about shared memory, we are going to show in broad terms how two different programming languages, such as JavaScript and C++, can interact with each other. Specifically, we are going to introduce the concept of shared memory and illustrate an example in which two processes interact through this data exchange system.
In the first part we will give some useful definitions to better understand what we are going to explain later in the second part, in which we present some examples of commented code.

This post aims to be an entry point to the docker landscape. It will show a basic docker concept and provide a simple example in order to better understand this technology. In this post we will talk about:

the steps required to containerize an application
the setup of the docker network
the setup docker volume

The project’s purpose is to develop a simple nodejs dockerized application, which downloads all the audio files from a public youtube playlist. The application  concerns the following steps and stakeholders:

The user adds some video to a public playlist
Once the user is inside his private

Abstract

This article explains how to engineer an IoT on Edge solution, a multisensor scenario with a wide range of communication protocols. So, the solution proposed, called SMART-IO, is about an implementation of the complete stack to satisfy hardware and software requirements. Then, the engineering samples proposed is a unique System On Module (SOM) or MultiProcessor System On Chip (MPSoC) solution. They are based on Xilinx Zynq family, which allows to manage a high data throughput and low latency when it comes to data processing.

Introduction

The role of precision farming in the actual agronomic plants is crucial for increasing productivity and improving control accuracy. In this article, we propose a smart device, Arduino based and open source, for controlling a little greenhouse of carnivorous plants, called Nebul.IoT, that manages temperature and humidity and, in critical situations, controls the internal nebulization system.

Pynq is a famous framework that allows programmers to directly work with FPGA using Python language, which is very intuitive, so let’s take a look at it.

When we want to accelerate a specific software portion, it is generally difficult to interface to it correctly, because you have to synchronize the CPU (generally referred to as Process System, PS) to the FPGA part (generally referred to as Programmable Logic, PL). In modern SoCs, we use the “axi” interface to make the two parts communicate, but its Hardware Description Language (HDL) implementation
