Documentation is about structure and discipline (Photo by Nátalie Rodrigues from Pexels)

Documentation is one of the most valuable assets you can create as a software engineer, obviously, the most valuable one will be the code you are producing, and that’s perfectly fine, however, in the times of misunderstood agile (not only agile) we (whole industry) tend to fall into trap of thinking that documentation is some “extra” addition that can be skipped and taken care of in not-defined future. The problem with this thinking is that in the future — context is gone, and without context, you can not produce valuable documentation. If these words do not speak to you —…

It’s python

There is plenty of similar articles on the web, but I just thought that I can add my perspective on the topic, and make the “tricks” list more complete. The code fragments used here are somehow crucial to my workflow and I am reusing them over and over again.

Sets

It’s often the case that developers tend to forget that python has set datatype and trying to use lists for everything. What is set? Well, long story short:

A set is an unordered collection with no duplicate elements.

If you get familiar with sets and their logic it can solve a…

Do you see cracks already?

It’s the end of the year — 2020 — a year that will be in our memories for a long time, as it removed our feeling of safety and forced us to ask hard questions about the future, however, it’s still a good time to write a summary and mention lessons learned from my personal perspective. Let us dive in.

The format of this entry will be close to a journal and I will share my personal experience, as it’s personal it doesn’t necessarily apply to you, but maybe you will be able to find some meaningful lessons here.

Me

The…

Introduction

The idea for the article came to my mind a long time ago, when I was already working remotely, before the COVID era. Since then I am often questioning myself — what is the ideal remote setup (also recently I’ve started to get more and more of those questions from my family members and friends)? And I’ve realized that to properly answer this question — I need to analyze it on multiple dimensions. In the last 18 months, I’ve been leading the organization which one of the most important principles was remote first organization. On top of that, I’ve been…

Introduction

I am in the IT industry for quite a long time and somewhere on the line, the idea emerges that full-stacks do not exist — and I was always really skeptical about this idea. I believe I have plenty of arguments to defend this hypothesis. Of course, this will be my personal opinion on the topic, but with a solid background and maybe with a bit of luck this article will trigger some discussion and will help me to understand the other side — which will be: Full-stacks actually do exist.

What does it mean to be full-stack?

First of all, we should start with a definition…

Context

I start to ask myself a question recently: How hard can it be to copy functionality of Bitbucket pipelines, Circle CI or GitLab like tools? Of course, there are years behind development of each platform - and probably hundreds of developers behind - yet the scope of the single blog post entry is very limited, so I for sure need to do some simplifications here, but before we jump into basic requirements definitions - get back to the context for a second. In this post, I will try to mimic the basic features of modern CI/CD tools. …


Sorry ghost.io

In this piece, I’ll show you how I created my own blogging platform with my own CI/CD pipeline. Sound crazy? It is a bit, but it’s also a lot of fun.

Context

I have a blog (the one that you are reading right now!) and until a couple of days ago it was hosted on ghost.io. Now it is hosted on my own EC2 instance in AWS using CloudFront as CDN. Some would say this is like shooting a cannon at a fly, but the case is that I already had this instance as another tool that I am using is…


After Bitbucket announced their pipelines — I was little skeptical. You know — after circle ci — is there any other CI/CD environment that can compete? After some testing it appears — that it can. Basically I was able to set up fully working CI/CD flow for my python/django project.

In this post I will try to introduce how to setup basic flow for the Bitbucket pipelines. Because of the obvious reasons — I will write a setup for backend application written in django — it is my main field of expertise.

Maybe start from the beginning and definitions.

What is CI/CD?

Python for the win!

I am often asked with question like this: How can I become a python developer? or I want to be a backend developer - could you give me some hints? Well, I think that I can :) So lets start. Please - if you are really interested click on all links that appears in text below.

Backend

First I need to make some clarification here — lets say that backend developer is responsible for creating and maintaining the API (Application programming interface) for the clients — web and mobile ones. …

Well, first — it really solves problem. Trivial one, but still. Second — I just want to get familiar with Slack Application submit process and Slack API flows. I think that such experience is nice to have as a backend developer. You just want to be able to provide integrations for your sophisticated solutions.

So what Sprintero does?

Basically it allows to get a random name for the scrum sprint — currently it supports names from the Marvel world — I’ve found the data on github from the creators of marvel wikia — I even send them an email — if I can use…
