Google Professional Cloud Architect

September 20, 2021

After having renewed the Google Associate Cloud Engineer certification, it was the moment to renew the Google Professional Cloud Architect certification as well. Since I wanted to keep Windows on my laptop for the smallest amount of time possible, I decided to book the Professional Cloud Architect exam the day after the Associate Cloud Engineer one. On the exam day (18th of August), having had experience the previous day, I ensured to set up everything correctly.

Google Associate Cloud Engineer

August 25, 2021

A couple of years ago, I obtained the Google Associate Cloud Engineer certification, so it was re-certification time. Since it is August and probably also due to the whole ongoing health situation, I’ve not found any test center at a reasonable distance. Therefore, I’ve decided to use the Online Proctored option. Google relies on Kryterion for their exams, as many other companies do, since Kryterion has more than 1100 associated test centers and, at least in the ICT certification space, it’s one of the most commonly used networks.

CORS headers with gRPC-Gateway

July 28, 2021

A few years ago, I wrote a blog post on managing CORS headers with Negroni. Lately, I’ve created a new API server that needed to be accessible from the browser, but this time I used a different technology, more precisely gRPC-Gateway. Few months after I wrote that blog post, I stopped writing new REST services by hand. I did not rewrite all the services that used the old paradigm just because they needed a fix or a new feature, but for all new services, I moved to gRPC with gRPC-Gateway.

Sensible datetime scale for Gonum Plot

June 28, 2021

Few months ago I posted a library for sensible int scale for Gonum Plot. There is a similar package I’ve developed to handle timescales. The integer one, being based on a recursive function, works with any number scale. Differently, this one will only work well with a timescale between 2 days and a couple of years. Extending it is not hard since it’s enough to add additional case statements in the switch, but I’ve not found use-cases for different timeframes so far.

GDPR - 3 years later

May 31, 2021

Three years passed from the moment the GDPR become binding law in the European Union. On the one hand, I’m happy that it has already been three years, but on the other hand, I’m impatient to see GDPR fully applied. Cookies Cookies are always a hot theme when we talk about GDPR. I still see websites handing out cookies (first and third parties ones) without a cookie banner or to users who have not pressed the “accept” button on the cookie banner.

My immutable Fedora

April 29, 2021

For many years now, I’ve been using immutable versions of Fedora. I remember that I started to play with immutable Fedora back in 2015 when Fedora Atomic was new. I liked the idea since the first time I’ve read about it, but in the beginning, I did not spend too much time making it work on my setup because it seemed a little bit too complex. At DevConf.cz 2016, I met Patrick Uiterwijk, who was running his spin of Fedora Atomic.

Red Hat Certified Specialist in Services Management and Automation

March 31, 2021

Late last year, I’ve read that a new Ansible-related exam was available: the Red Hat Certified Specialist in Services Management and Automation exam (EX358). I’ve taken and passed this exam at the end of January. It was the first time I did a Red Hat exam that was brand new and without having the possibility of finding online some opinions around it. Some people have reported for other exams that when new exams are launched, the scoring has issues.

Red Hat Certified Specialist in Advanced Automation

February 1, 2021

In my pursuit of the Red Hat Certified Architect (RHCA) certification, I’ve taken the Red Hat Certified Specialist in Advanced automation: Ansible best practices exam (EX447). As for the other Ansible Exams, you can always consult the Ansible documentation available offline in the exam system. Different from the Red Hat Certified Engineer exam (EX294), this exam also includes Ansible Tower as a topic, so be sure to have good knowledge of it as well!

Sensible integer scale for Gonum Plot

January 20, 2021

Over the years, I found myself multiple times using Gonum Plot. I do find it as a very good and easy to use plotting tool for Go. The problem I found myself, over and over, dealing with is the tickers scale. If you know before-hand the values that can be expected to be created by the application, it is very straightforward, but the majority of times, this is not the case.

Red Hat Certified Engineer

December 28, 2020

At the beginning of this month, I took the EX294 exam, which allowed me to obtain the Red Hat Certified Engineer (RHCE) certification. It was the first time I attempted the RHCE exam, but I prepared myself in the past for the EX300 exam, the exam that allowed you to obtain the RHCE certification in the RHEL7 time, but never got around to do the exam. Compared to what I had to study for the EX300, I found the EX294 program way more sensible.
