Why time and space complexity is important for your job

Most software developers are always looking to improve their skills and experience. What is the last cutting-edge technology I can learn? what antipatterns should avoid? what are the new updates of my favorite framework? These things are important for all of us and for the companies we work in, but in all this chaotic mess of libraries, conventions, patterns, … we could easily forget the basics that we learn when we studied the concepts of algorithm design: “an algorithm should be efficient”. But, is it really that important? when should we worry about that?

Some time ago, at my company, we had the problem that certain parts of our users should use some different versions of our services depending on the subscription plan that they have at that moment.

How to amend commits using SourceTree/CLI

Amend commits

Git is an excellent tool to safely develop applications with total control of our source code. It can be used to track changes, collaborate with others and save your work in remote in servers that GitHub or Bitbucket offer us. But all people have bad days and mistakes can occur at any moment.

Should I create a new app? What technologies should I choose? What if my idea is not original? How big this new project should be?

Welcome to CodePull

Welcome! This is the first post of CodePull, a blog project that I wanted to arrange long time ago. Let me introduce myself, my name is Alejandro and I’m a software developer. I’m passionate of last technologies, best practices and all topics related to Computer Science… and yes, I can consider myself a geek 🙂

What I’m looking for by creating this blog is a place to share my knowledge or experiences that could help you out someday. All the topics are welcome and suggestions will be highly appreciated.

Also, I’ll try to find some collaborators that like me, they would like to spread their skills or thoughts using this platform. Everyone is welcome in this blog!
