GitOps Lifestyle Conversion

I’m currently fascinated with Gitlab’s handbooks. I heard of companies trying to be more open to the public, but the extent that Gitlab is doing is unprecedented. They are documenting everything publicly. Most, if not all, internal processes are getting written for everyone to see.

  • How admissions are done? It’s there.
  • How and when employees are bonuses? It’s there too.
  • What is the ERP used? It’s there.
  • In fact, what is the whole list of external software and service used? It’s there too.
  • The scripts used to manage it’s own site? It’s there too.
  • Personal information, like employees actual salaries? Of course, are not there.

Too much information? Maybe. But it’s definitively inspiring.

Another source of personal inspiration comes from a guy on Twitter: Keijiro Takahashi. This Japanese programmer does several mini-tools for himself but publishes everything on Github with minimalist’s licenses like MIT.

In contrast, I was checking my LinkedIn the other day then I decided to share my Gitlab and Github accounts. There are so many projects over there. #ButNot. Most, almost all, were private! Many game prototypes, small side projects. All locked. Some are basically live backups, since are not updated for ages. So I decided to do two things:

  1. Open some of the closed projects
  2. Git-fy some of my personal and professional projects
  3. Documentation as code for my new company

The first is pretty straight. Mostly checking a box. Sometimes adding a small README or LICENSE files. Few times making real changes.

The second is a new mindset: I have dozens of small projects, from games to personal scripts, that I’ve never used git to track changes. But not only I could get better control of it, but also I could share with the world. You will see more and more projects popping up in my Gitlab account page.

The third, follow partially Gitlab’s way. I’m considering in documenting most of the processes in git-like wikis. It will not only good sharing the knowledge with other employees and partners. It’s also good for tracking the business decisions that changed these processes. A rather clever approach.


Certification and Credibility

Can you prove what you claim?

Do you fully trust in the media, banks or advertisements? I bet you don’t. And you shouldn’t. Not blindly. Trusting is a very delicate matter.

By living in a society you are required to trust other people. That’s the way to share the responsibilities. Each individual do a thing for another. You simply have to give a bit of trust in others. If not the if we should trust, the problem lies on how.

Source of Trust

The primary source of trust are the individuals themselves. You gain trust by living and presenting reliable results. It takes time.

Governments, on the other hand, use the power of law to reinforce what they want to be believed. They issue money, certificates, documents and they all MUST be accepted as they were the truth. What makes you believe that a $100 bill is worth the $100? Simple: the law says it so!

If you need to be trusted but you do not have the time to gain it organically nor cannot “fabricate” the trust? The solution lies on a already trusted third parties vouching, a…


Someone that you trust can vouch, give their word, for another one. That works like a web of trust. I trust my mom, that trusts her old friend. So, I might trust her too.

Language and professional certifications are the most common form. Several institutes, for a very diverse range of fields, can issue a certificate saying that you are good as you claim. Proficiency in Mandarin? Project management? Someone can certificate that you master it.

Double Agent

Certification agents must be impartial, indifferent from your own success derived from the certification, otherwise they might be incentivized to lie for you. It breaks the whole point of the certification as source of trust.

  • Accounting firms hired to validate a client company financial health might be interested in lying. The at-the-time famous Arthur Andersen participated in a giant fraud stating that it’s client’s, Enron, finances was ok. Enron bankrupted months later and AA was suited and had to split in two companies.
  • The 2008 financial crisis also can be attributed to rating companies, that stated that several risky bonds were good and risk free. They help clients to sell them to others, profiting from lying.
  • Some colleges graduate their students even when they have really bad grades. Flooding the market with awful professionals, it becomes impossible to assert which one is good and which one is bad.

There are several good certification institutes. But these authorities have to be constantly monitored. Also, their own processes have to be constantly certified, creating a big process of checks and balances.

It’s a worthwhile initiative for the whole society.

Google Cloud Architect Certification

Less then a couple of months after I got certified as a Project Manager, I decided to invest in an area that I was not fully confident that I know the stuff: defining cloud architecture. I started to create, develop and manage cloud systems for just the past 5 years or so, and it evolved really rapidly.

So, applying for a such certification would require an extra study by my part. There were areas that I definitively do not grasp, such as networking and many Kubernetes corners. I decided to go with my beloved Coursera. I did a couple of free and paid courses there and I love it. Also, it which was the official training platform for Google products and services. Google itself design the courses and their employees that teach them. So there is some comfort.

The course is very practical. They provide a demo but real user to allow students to act in Google Cloud environment for real. So one actually interact, create, update and delete real things. It’s a major factor. Hands on baby!

I went to the examination was much more relaxed. They were as much as professional as the PMI guys, but more relaxed and humane. I passed.

I definitively learned a lot. It will help me in the future and current projects. Even being a Google Cloud focused, it addressed many of the issues of a generic cloud architect in any provider.

I can assure I can handle the job. From computing, serverless, storage and, yes, networking, I’m pretty confident I can design a better pretty cost-efficient solution than before. In the evolving cloud business, as long I keep updated, it’s a new passion that I am really excited.

Project Curva

For the last 9 years, I’m working as a planner and controller of multinational Brazilian oil company. The team consolidate all the planning information of all the company, analyses it and reports to the company board of directors.

For all these years, I’ve struggled to deal with some basic business scenarios:

  • At the very end of the process, someone in the chain of information submits a last-minute update that cannot be ignored
  • The board decides to change the plan
  • Existence of multiple simultaneous plans, for optimistic and pessimistic scenarios
  • Changes in the organizational structure

The current information systems used or developed by the company are simply too restrictive to accommodate their business cases. The general solution is to create entire systems using dozens of spreadsheets. This a patchwork of data, susceptible of data loss and zero control.

To address this, I decided to develop myself a system that is both flexible and powerful. The overall core propositions are:

  • Versioning: instead overwriting data whenever there is a change request, the system should be able to preserve the existing data and generate another version. Both should be accessible, in other to allow comparison and auditing.
  • Branching: not only sequential versioning (v1, v2, v3), it should allow users to create multiple current versions. Creating scenarios of event temporary exercises should be effortless.
  • Multiple dimensions: for each unit (ie, a project in a list of projects), the user could insert the future CAPEX, OPEX, production, average cost, number of workers or any arbitrary dimension. It’s all about capturing future series of values, regardless the meaning.
  • Multiple Teams: in the same organization, users can create inner teams that deal with different aspects of the business. The system should allow to users set the list of units to control (projects, employees, buildings, or whatever), their dimensions of measurement and then control the user access of all this information. It’s a decentralized way to create plans.
  • Spreadsheet as first-class citizen: small companies might not use them much. But any mid-to-big companies use spreadsheets for everything. Importing and exporting system data as Excel/LibreOffice/Google Docs is a must.

With this feature set in mind, I started to create a spear time what is now temporally called Project Curva for the last 3 months. I will post more about it in the future: the used technology, the technical challenges and some lessons learned.

A beta is due to the end of April, 2021.

Project Management Certification

After months studying, finally I could accomplish an old dream: be a certified project manager. I work with projects since the dawn of time.I create personal and professional projects often. Big and small. For myself, with teams and for the company.

Despite liking dealing with processes, my goal was never to be in a process driven career. In fact, the part I like the most about processes is their implementation or optimization projects!

And I genuinely try to enhance my own abilities, studying, researching and training. I’m a agile advocate at my job long before it was a thing. Now they are all project-fying and agile-ing all major parts of the business processes.

But one thing is to know you are good at something. Another things completely different is to convince someone about it. Here comes the certification program. PMI is de-facto institution regarding project management. I read their main material many many years ago and followed their general guidelines ever since. But the certification itself, nope.

Better later than never. I decided to finally apply for the certification exam. Here’s a motivational tip: first apply for a exam than start to study for it. It’s much more effective, psychologically speaking, to have a fixed deadline to be engaged and motivated. Studying for a “to be defined” date is prone to procrastination.

I bought an online course. The instructor was very clear: each exam has it’s own quirks and style. He will exploit PMI’s style to deliver a laser-focused course with the only goal is to facilitate passing the exam. No philosophical discussions. No discussions at all. Just the pure content. Delivered with the precise method.

It was both effective and efficient. It took me just a week of classes and an extra to review and consolidate the knowledge. PMI requires that one should have not only a previous experience in the field but also a minimum amount of formal education, so the classes could not be shorter even if was possible.

I did the online exam. Man, it was equally scary. Some dude have to check our computer screen, I had to turn on the camera all time. And any movement or sound, I was called upon.

The questions were super generic. It’s the downside of being a generic Project Management certification. It was not about construction or software development. So the online course was right. After a couple of hours, exhausted (I had to do it after the business hour, so I was extra tired), I finished.

Days after, the good news: I did it! One old dream checked! And it’s on my Linkedin, of course!
