Sprint 1 – Retrospective

Sprint 1: 01/22/2020 – 02/19/2020

During the month, I started to work as part of the UpdateGuest time for the LibreFoodPantry project. The Sprint started with sharing and learning general knowledge about the project, what are the services to be offered, and some future perspective. As I learned the service that I and my team will be supporting, we began to fill the backlog with to-do tasks. We operated as a Scrum team, managing a Scrum board in GitLab, and separating stories based on requirements.

We started this sprint by learning new knowledge. As we decided to with the MEAN Stack, we needed to gain knowledge in all technologies that will be used: MongoDB, Express Framework, Angular, and Node.js. So we created stories to track our learning timeframe and weight the knowledge we gained.

During the Sprint I worked in multiple stories and supported the team in different topics:

  • #1– I created the Angular App, the Mock version of our UI service. I supported the team with discussions on how the App should be implemented and organized.
  • #2 – I supported to edit and fix an issue we had with .gitignore file. Together with the team, we discussed how to fix this issue and concluded with a good result.
  • #3 – I created the Document and designed the Frontend Architecture for out UpdateGuest. This document will support the implementation of the service. This document will be edited during Sprint 2
  • I supported the team with PR reviews, issue discussions, and research when we had knowledge gaps.

The end of the first Sprint consists of secure knowledge and the beginning of work with UpdateGuest service.

In this retrospective, I and my team need to reflect on these points:

  1. What we need to stop doing
  2. What we need to do less
  3. What we need to keep doing
  4. What we need to improve

1- What we need to stop doing

We should stop Approving PR by only one person. Each member of the team should approve a PR – so we know that we are all on the same page.

2- What we need to do less

We should be careful when we create new stories and check if there are no duplicates.

If there are duplicates, before closing the story we should let the creator of the story know first.

In the case of merging a PR, the creator of the PR should merge, or if another person do it, we should let the creator know first.

3- What we need to keep doing

We need to keep working with stories that we have on the Sprint backlog.

We need to discuss issues that we may have during the sprint and approve each other work.

We should keep reviewing each story before we mark them as DOne and close them.

We should keep solving debatable conversations and conclude in a good result that works for everyone.

4- What we need to improve 

We should have better communication for each story, issue or blocker during the sprint. Class meetings are not enough to solve issues. For each story, we all need to discuss and communicate with each other, and to consider all opinions before we conclude to a solution. Communication is the key to success for a team.


As a team, we successfully closed Sprint 1. We closed most of the stories in Sprint’s backlog and supported each other to move to the next sprint. We had a Sprint review for what we did, and a Sprint planning for Sprint 2, so we are prepared for the next step. So, let’s start implementing our ideas!

Use Your Title

I’m promoting you from Senior Engineer to Lead Engineer. The pay is the same but people will disrespect you less.

—Dilbert’s Pointy-Haired Boss

“Use your Title” is a very effective pattern for those who feel like the title they have is everything in life. We all have our own goals in life, and we approach differently to achieve them. For some, a software engineer position is all they have wanted to achieve in life, and there are others who would not feel accomplished until they become seniors or leaders in the industry. On the other hand, it happens to have an unimpressive title, even though you have given more authority in your position than your title or job description says. In this case, people get discouraged and lose hopes that one day they would get what they deserve.

In my opinion, we should “Use our Title” in a way that benefits us professionally. Titles are only made to feed our egos. What is more important is that we should never stop learning or stop searching for better opportunities that would complete us professionally. Let’s think of it as climbing mountains. The second highest mountain in the world is K2. If a person’s goal a year ago was to climb that mountain, he/she would feel accomplished when he/she gets there, but then he/she would feel the need of having another goal to achieve and would end up climbing Mount Everest. This tells us that even when we get to have the title we always dreamed of in the industry, there’s more we can achieve.

In this pattern, I found interesting the part that suggests writing down a long and descriptive version of our job title. I think this would help us reflect on what we do at our workplace, if the title matches with the authority we have given, and maybe find the need to update the title with superiors’ permission. I, myself am going to try and see what I find out when it comes time to update it.
As a conclusion, make sure your skill level matches your job description and title, and no matter how far you go with titles, remind yourself that your apprenticeship is not over.

Sweep the Floor

In the craft tradition, newcomers start as apprentices to a master craftsman. They start by contributing to the simpler tasks, and as they learn and become more skilled, they slowly graduate to larger, more complex tasks.

—Pete McBreen

Sweep the floor pattern shows that an apprentice can work very closely with experienced professional people of any industry, but they cannot be equal with them since the first day they start working on the company. First contributions to the company by an apprentice are usually small and simple tasks, because the team you are part of, doesn’t know where you fit better, nor do you. As bad as this may sound, “sweeping the floor” is a very good start, because you show to your superiors that you can do small things with high quality, and in the future, you can do greater things with the same quality.

What got my attention is Paul’s experience in a software company. He was aware that he couldn’t write code at a certain time, so he accepted to contribute to the company differently, by even sweeping the floor for real. He was only 17 when he first started, but slowly he started doing more technical assignments, like updating the content of the website or working on the backup. These tasks helped him a lot to gain the trust of the team. Since he was able to do the small tasks right, later Paul would be the same passionate person to do something huge in the company. But let’s not forget that it doesn’t matter how small or big your assignment is if you do something with passion and get the best out of it. As it says on the pattern: If no one sweeps the floor, then the glamorous work can’t be done because the team is hip-deep in the dirt. Every role is important, and no one should be ashamed of their job!

In my opinion, being an apprentice is very useful after you graduate. Courses you have taken during college, will not be everything you will need when you become an apprentice. Being able to start from the dirt, will help you understand step by step how things work in the company. Not everybody is ready to start from the dirt though, especially people who have some experience in the field. However, depending on your commitment to learning everything, in the future, you might be able to do great things on your own. As a conclusion, take the opportunity to Sweep the Floor, and make sure you prove to yourself and to the team that you’re worth doing something greater every day.

Confront Your Ignorance

If we value independence, if we are disturbed by the growing conformity of knowledge, of values, of attitudes, which our present system induces, then we may wish to set up conditions of learning which make for uniqueness, for self-direction, and for self-initiated learning.

-Carl Rogers, On Becoming a Person

Every day of our lives, we find ourselves surrounded by people who know more than us. It is normal to not know everything. This is why we shouldn’t go hard on ourselves when we meet people who expect us to know more than we do. The best we can do is to confront our ignorance, which means to identify gaps in our knowledge and try to fill those gaps continuously. The “Confront Your Ignorance” pattern shows us different ways to approach when we find those gaps in our knowledge. Some of these approaches are: to read the introductory articles and FAQs, to love what you do in order to understand it better, to work with others who have more knowledge than you in a specific topic so you can learn from them, to learn in public and not in secret. As good as this pattern can be, sometimes the apprenticeship can become a problem for the team at work.

This pattern made me realize how important it is to confront and expose my ignorance. Sometimes I get too hard on myself, such that I forget that I am in a learning process and it is okay not to know everything. From now on I will write down everything I find it hard to understand and start working on getting better on those. It could be a skill, a technique or any topic, but that would be a good start towards a great future full of knowledge.

What got my attention is the fact that “Confront your Ignorance” and “Expose Your Ignorance” patterns are very close to each other. By doing a list of the things we don’t know, and the things we should know in the future, we’ll be able to learn where our gaps are, but exposing them to the world help us learn even faster, and get help from the others as well. Facing your ignorance alone leads to stubborn knowledge that never takes action, but reveals your confusion without seeing it as a question that must be answered as soon as possible. As a conclusion, confronting your ignorance is very important in our daily work, especially when our purpose is to be successful in our professions.

Learn How You Fail

Ingenuity is often misunderstood. It is not a matter of superior intelligence but of character. It demands more than anything a willingness to recognize failure, to not paper over the cracks, and to change. It arises from deliberate, even obsessive, reflection on failure and constant searching for new solutions.

-Atul Gawande, Better

Learn how you fail is the first step towards learning how to win. The objective is to gain self-awareness of the reasons which lead to failure, and then make better decisions by reducing the inclination towards idealism. Being conscious that you cannot know everything, is the only way to become aware of how you fail. Knowing your own limitations, allows you to deliberately identify obstacles and concentrate on the goals you can reach.

Yes, you will fail! What’s more important is that you will win, once you know why you failed. The way to get the best out of it is to create a system to prevent the failure from happening again after you have figured out what went wrong. Creating a checklist or a type of protocol to prevent it from happening again when you find the weak point is another option to not go through failure again.

In this pattern what got my attention is the last sentence, which says “if you’re brave enough, get a friend to review your code, and see what else she can discover”. This is very accurate because everyone who writes code knows that there will be errors and it will take time to fix them. Even though you fix the errors you get, someone will find something else for you to fix, especially when you work in groups. This can be very tough because you feel like you are falling down. The reason why this happens is that we feed our brains to always win, and never lose. We reach the goal because we know how to do everything, and there are times when we do not reach the goal because there is something, we had no clue about. Is it time to step back? No! We should go through the failure, learn why you fail, and try again if you think you’re capable to fix it. As a conclusion, it can be very painful to learn how you fail, but in the end, you will have the skill to accept whatever life throws your way.

Record what you learn

“You should not also underestimate the power of writing itself…You can lose your larger sense of purpose. But writing lets you step back and think through a problem. Even the angriest rant forces the writer to achieve a degree of thoughtfulness.”

Atul Gawande, Better

Record what you learn has the purpose to make everyone able to memorize things for a very long time. Using this pattern, it’s not just about writing down notes in a paper and then forget about it. It is about writing down the information you need to learn and read it continuously to keep that information stored in your brain. Keeping a record of your lessons to a blog or personal wiki, it is not a bad idea at all. You decide whom you’re going to share it with, or not share it at all. As long as you write down your notes and get back to them to read or even to make improvements, your brain will be in the perfect shape of memorizing things.

This pattern made me realize that taking notes and writing the most important parts of the lesson is not the end of the learning process. Most of the time when I have to learn something new, I write pages and pages that never end, read them, and then I write a summary without looking at the notes. The problem with this is that after I am done with that lesson, I don’t really go back and read those notes, nor the summary. I wonder if I still have those notes?!

I found this pattern very useful and interesting in my career. Starting from today, I will keep track of my writings, add more details to them, and stick the date they get written, so that when I go back, I would find very organized writing that would make me go back to it over and over again. There is no better thing as reading constantly and memorizing useful information. Another important part of this pattern is that when you go back to read you realize how much things have evolved for a specific topic, and you ask yourself if you should update the original or not? In my opinion, the same as everything nowadays gets updated, writings need an update as well. As a conclusion, keep a record of your writings, the same way you keep a record of bank transactions…

Introduction to Apprenticeship Patterns

If you are close to graduation as a Computer Scientist or Software Developer, the market for you will be huge. There are unlimited opportunities in the Tech field but should really be prepared for that. How do you see yourself in the professional world? Where do you see your starting point, and what are your future goals? An inexperienced Software developer, you have to be an apprentice, and following the long way of this journey, you will be a master, unless something goes wrong – like really wrong.
Reading “Apprenticeship Patterns” by Adewale Oshineve and Dave Hoover, will give you the first jump on the “Software Craftsmanship” world.

The term Software Craftsmanship is used to illustrate the skills you need to be successful in this journey. Being a Software Craftsman, you don’t need to have coding skills, you need creativity, you need to build your crafts, design your ideas, solve the problems avoiding complexity. Sounds fun, right? Yes, it is actually fun if you enjoy it, and if you know how to start from point zero. Imagine if you are a baby: you need to learn how to walk before traveling the world. You need to learn how to talk and read before being a scientist. So, you must be an Apprentice and follow the pathway that is important for you. One step at a time, learning from your masters and applying your skills will make you jump to the next phases. However, if you need to maintain your skills you don’t need just to practice them, you should also pass them to the other people.

At this point, you will not be an apprentice anymore, you will be a journeyman! Being a journeyman does not mean that you do not need to learn anymore, you should still follow your mentors, they will still be your masters who open new doors of your mind. You will still be focused on your craft, your ability to develop your skills, to advance the complexity of your designs. As a Journeyman, you should have created your portfolio, which represents your experiences, your knowledge and your ability to be a craftsman.

Next step, you will be a master. As a master, you will be an apprentice: you will keep learning and develop your skills, you will be a journeyman: you will keep building your portfolio and expand your craftsman ability, and Master: you have to move the industry forward and pass your knowledge to the new apprentices. Being a master means that you have all the needed skills and experiences to be a true craftsman. You will have the ability to design, architect and construct your crafts.

As you go through this journey you will need to make important choices. You should always need to be careful about what you choose, money or experience. Money can give a good life, financially, but skills and experience give you more opportunity and open more doors for your future. Ready to start your journey? Good luck…

LibreFoodPantry: Communication

LibreFoodPantry has plenty of interesting information, but what got my attention was the Communication part. I think communication is very important for a team to succeed. Having so many options to communicate with each other, makes it so easy to solve problems that might come in our way. The issue tracker is a great solution to communicate and keep track of issues while working on the project. On the other hand, Discord and Google groups, get together not only students but mentors as well. Being a member of the LibreFoodPantry community gives us equal rights to communicate with each other using those tools. We all know that developing face to face is not always enough, and we all end up doing most of the work outside of class. We are lucky to have such useful communication tools that will make communication easier for us while working on this project.

Unified Modeling Language (UML)

curso-de-uml-2-Nowadays, Unified Modeling Language has made it easier to describe the software systems, business systems, and any other systems. Their graphics show an explanation with words and pictures also, which proves that UML is practical and anybody should be able to use it. UML first appeared in 1997 and its content is controlled by the Object Management Group. The primary contributors to UML are Grady Booch, James Rumbaugh, and Ivor Jacobson.

UML Basic Notation


Why UML?

UML has been able to unify the terminology and different notations, which leads to a great communication between all parties, on different departments of any company. It is also much easier for co-workers to get access or transfer information, while they are working on the same project. UML seems to be a very powerful modeling language, which makes it perfect to use, even for small projects. Stereotypes can extend its functionality if it is not sufficient for some kind of projects. UML did not come from anywhere, it started from real-world problems with existing modeling language that needed modification or transformation. This is why it is widely supported because it guarantees usability and functionality, based on real-life problems.

UML 2.0 defines 13 different types of diagrams, where each of them may be expressed with different details. They are classified into three categories: Structural diagrams, The Behavioral Diagrams, and The Interaction Diagrams.

–          The Structural Diagrams represent elements that are static in nature and they can be fundamental to the UML modeling of a system. This contains:

The Class diagram, The Component diagram, The Composite Structure diagram, The Deployment diagram, The Object diagram, The Package diagram.

–          The Behavioral Diagrams represent the modeling of how the system functions. This contains:

Use Case Diagram, Activity Diagram, State Machine Diagram.

–          The Interaction Diagrams represent how the flow of data and control work on the modeling system. This contains:

Communication Diagram, Sequence Diagram, UML Timing Diagram, Interaction Overview Diagram,


As a conclusion, the Unified Modeling Language is an internationally accepted standard that is used for Object-Oriented Modeling and can be used to represent a model that adopts the best software architecture practices.
