sharing thoughts and ideas in the coding universe!
When we start learning and experimenting with the machine and deep learning, the most convenient way is to use Google Colab. There is no point in spending time setting up libraries, selecting operating systems and deciding if we will buy a laptop with a GPU or a desktop. The wisest thing is to buy a

Factory pattern is another prevalent pattern that we need to know. The main principle about the factory is that it separates the creation from use. But what does this means? We design a factory entity that creates the objects we want depending on what we want. We do not use the constructors directly on the
When talking about patterns, one acronym seems to be the most popular, the SOLID principles. Yes, actually SOLID is an acronym that stands for: Single Responsibility, Open-closed, Liskov substitution, Interface Segregation and Dependency Inversion Too many strange terms, a little bit dry. I can think of two things that will help us go through. The
We have started a series of posts trying to present ridiculous popular design patterns using examples in modern C++. Again, the inspiration came from the great youtube video series, ArjanCodes. This time we are going to talk about the observer pattern which is going to help us separate various modules in our code. The key
It’s always wise to use continuous integration (CI), even in our hobby projects. When working with C++, it might be painful to install the required dependencies, even for the most essential packages like the googletest for the unit tests or the spdlog for the logger. In those cases, using Conan package manager is a no
Dependency inversion is one more pattern that is going to help us improve abstraction. We mean that by applying this approach, we separate the definition of an interface from the actual implementation. To explain the pattern, there is a classic example with the light bulb and the switch. If we assume that we want to
In this post, I’m going to talk about the strategy pattern. As I have mentioned in a previous post, my initial inspiration started as I watched ArjanCodes youtube video tutorials. In of those (link), he began to explain the strategy pattern. This approach comes in handy when we build a structure, and we could have
Perfect is the enemy of good. That’s the case with the IoT backend system that we described part I. In our previous post, we went step by step through the procedure of setting up: MQTT server to listen in incoming topics, e.g. sensors, Influx database to store time series of sensor data, Telegraf to connect
To use the correct tools to implement a task is so important. When playing with IoT applications, you will inevitably touch: MQTT, for handling easily the messaging, InfluxDB database, to store the data in a timestamped fashion (time-series arrays), and Grafana, to visualise the data This is good, but do you mean that I need
Test-Driven Development (TDD) is a popular approach in developing code bases and there is a good reason for that. There are many books that explain the way and the advantages of adopting an approach like that. In today’s post, I’m not going to explain that again. An amazing book that I can suggest is the
