Golang for Rubyists. Part 4. How Go functions are different from Ruby methods

Good morning, my dear readers, today we will talk about a concept, without which no software can be developed! Ok, not only without this concept… And actually, it can be…
Ok, never mind, it is still a very important topic if you wish to get the hang of Golang!

Golang for Rubyists. Part 3. Ampersands and asterisks. Pointers and references.

Welcome back, my fellow learners.
I still on my way of learning Golang and recently stumbled upon some listing, where I’ve found asterisks and ampersands, which I couldn’t get the hang of and had to google. So I think it is a great topic for the third post in the series.

JS on Backend in 2018. Tutorial. Part 2. Adding a database and Sequelize ORM.

After the previous post, our application server works, can receive requests and even return some kind of responses, which is already great and you can go into production with it! But probably it would make sense to add some more functionality to it. And in this post, we will integrate a database and implement a RESTful API.

Developing a database. Part 1. Why may you need indexes and how does Hash index work.

I plan to write a series of posts about databases internals. In order to make it easily perceivable, I’ll be writing a NoSQL DB from scratch in Ruby. No doubts that it’s not the best fit for database development, but it’s extremely readable and will help us a lot. This one will be about why may you want to have an index and what is a Hash index.

UPD. I decided to not continue this series because it takes too much effort to investigate deep enough to explain, but it had got much fewer views and likes than more applicable ones. Probably will return to this topic once, but not now.

Ruby on Grapes. Why did we choose Grape and why would I choose it again

Today I gave a talk on Ruby User Group Berlin meetup, here is a recap of it in a readable format.

In my team, we are building a new and fast-evolving SPA product. We are small in terms of a number of developers and we are agile in terms of the market. We test the design of an idea, quickly implement it, test it with real users, then either keep and improve or change or remove. Quite a quick pace, so when we were choosing the web framework we wanted it to be more a helper for us rather than a box, out of which we cannot step.

Amazon DynamoDB introduction

This post is the second one in series about Amazon Web Services first steps howtos.

I believe that traditional guides like AWS Certification preparation and Linux Academy don’t give the information in proper order, so here I give it in the format and the way how I give it to my colleagues at Babbel.

This post gives you an introduction to the DynamoDB and prepares a ground for the next practical lesson.
