All Ruby on Rails Node JS Android iOS React Native Frontend
Welcome to brand new series of content where we will share short tips and pieces of knowledge. This time Ruby on Rails! Recently I was working on separating gettext translations in our project into separate domains. It's very useful in cases when some strings should be translated differently in different contexts. I will explain shortly how to use multiple domains for Gettext translations in your Rails app. Enjoy!

MQTT Overview For Developers

Message Queue Telemetry Transport is a lightweight messaging protocol for small sensors and mobile devices, optimized for high-latency or unreliable networks. It works on top of the TCP/IP protocol. It has been used in sensors communicating to a broker via satellite link, over occasional dial-up connections with healthcare providers, and in a range of home automation and small device scenarios. It is also ideal for mobile applications because of its small size, low power usage, minimised data packets, and efficient distribution of information to one or many receivers. These qualities, along with reliability and some degree of assurance of delivery makes it a worth-to-consider solution in “machine-to-machine” (M2M) or “Internet of Things” products.

MQTT iOS Frameworks Comparison

If you are new to the MQTT or just want to refresh your knowledge, please read my overview of the technology first. The first step to build a stable and reliable iOS application with use of the MQTT protocol is to take some time to determine all use cases and possible scenarios. Based on that the expected specification can be created for the second step - choosing the right broker. The implementation of it on the server is not a task for iOS developer, but it’s important to know what are its functionalities and limitations. Only after that, the proper framework for iOS can be chosen. There are lots of the MQTT clients available. I had an experience with two of them: CocoaMQTT and MQTT-Client-Framework. However, there is also a third very tempting option, which is Moscapsule. The purpose of this blog post is to compare all three of them especially in terms of differences.

I really like Angular! At the time most of the well-written websites were MVC applications, Angular 1 was a huge revelation to me Yes, there were older frontend frameworks such as Backbone, but Angular was the first one that made a real difference. I could compare it to the first iPhone – there had been ideas, there had been attempts too, but finally, someone made it just right. Over several years, I did many projects using Angular or Ionic, and when the time came, I switched to Angular 2, which was even better in my opinion. Those days, as the frontend part of my developer’s stack, Angular was safe to me and provided a comfort zone.

A Quick Recap After EuRuKo 2017

Like last year, our Netguru folks attended the annual Ruby conference in Europe called “EuRuKo”. It took place in the city of Budapest, which happens to be beautiful and not very far away from Poland. This time, the event attracted over 600 participants in total, who had an opportunity to listen to two days' worth of technical and non-technical presentations. The talks concerned Ruby, Rails, software development, and working culture in general. We prepared short summaries of the talks we found the most interesting – have a look below!

There comes a time in life when you have to find your way, when you graduate from the university, or your secondary school, and here you are – young, ambitious and full of ideas. But where should you start? The market seems to be full of job ads. As a less experienced professional, you are looking for some opportunities such as internships or traineeships. So you start sending out CVs, and you are impatiently waiting for replies. I know this feeling, I was in this kind of situation too. I finally got my shot at a great career, and I would like to share my thoughts and experience with you about Netguru’s internship programme in the Quality Assurance department, which I had the pleasure to take part in.

IoT From the Ground Up

It was 2012 when I first built an IoT device without even knowing that such a term already existed. Its codename was Pinpoint, and the primary goal was to allow localising objects and collecting information on their movement, which could be used in logistics to monitor a fleet of cars. Having been completed as part of my Engineering Thesis, the work ended in the closet instead of hitting the market. Back then, I didn't realise that IoT era had already begun.
