gh is the new  Github command-line tool. I'm super excited about this new tool. It makes the engineers / devops engineer experience much better. It allows you to use github(not fully yet but the basics) in the command line, so you dont need to use the browser. GH is written in GO and I believe in the future we will have amazing tooling from Github to CI/CD using GitHub Actions. So let's get started.

Terraform is a great DevOps tool. Terraform has support for Custom Module which is a killer function. Functions allow you to take much more advantage of Terraform and avoid the right custom code in bash or other languages. Today I made a video showing some functions in terraform like how we can work Custom Module. So Let's get started.

Terraform is a great DevOps tool. Terraform has support for Dynamic Provisioning which is a killer function. Functions allow you to take much more advantage of Terraform and avoid the right custom code in bash or other languages. Today I made a video showing some functions in terraform like how we can work Dynamic Provisioning. So Let's get started.

Terraform is a great DevOps tool. Terraform has support for functions  which is a killer function. Functions allow you to take much more advantage of Terraform and avoid the right custom code in bash or other languages.  Today I made a video showing some functions in terraform like how we can work with external JSON files and use functions. So Let's get started.

JQ is a very powerful json processing tool. JQ is great because is written in C and is super fast. JQ also make json appear with a color highlight when you use it in Linux terminal. JQ is useful because you can combine with other DevOps tools like kubectl, docker, ectd, vault, and so on one. Basically, anything that returns a json output you can use JQ in order to process it. JQ has lots of interesting features and is possible to do pretty simple and yet powerful json processing. JQ allow us to subtract parts of the json document and also provide some powerful processing function like map, add, flatten and much more. It's possible to do some very high level and simple functional programming with it. Now let's take a look on Sheet Cheat I made for JQ.

When I start on IT, several years ago(+15), C was the first language that I learned. But was not the first language I mastered and deployed in production which was...surprisingly Visual Basic 6.0. However, when I learned C or any language back on that old and arcane time noddy was into testing. However now is impossible to work professionally in any language without tests. C is a low-level language but still kicks ass and has several interesting libs/frameworks. People use to fear C a lot because of lack of syntactical sugar but once you get used to it is not that hard at all. Today I want to show how you can do Unit Testing with C. I will not show how to do Unit Testing with C++ but with C ANSI actually. We will be using Check a unit test lib for C ANSI.

Let`s say you need monitor a box and see what happens in sense of CPU, IO, Network, Memory and you want see some nice charts? There is a great tool todo that is monitorix you can real good data and is very easy to get it running. Monitorix is very simple to use and have a very nice web interface . Today i will show how to install and run monitorix on Amazon Linux OS.

NTOP 2 is a great tool for linux monitoring. It`s focused on network and have all sorts of charts, visualization and network information you might need. Today i will show how to install and run ntop2 on Amazon Linux OS(CentOS based) this is not a straight forward task because there are lots of dependencies. This is very useful if you are doing Stress Tests or Network or Network Failure tests because you can see whats going on with plenty of details the whole thing is very colorful.

It's been a while since I'm using Martin proulx Facilitation Cards . I'm not using the cards alone I printed for each person in my team. The team receive the idea to use the facilitation cards very well and them we start using it. The experiment was a attempt to improve the communication in the team and see how people react using this kind of visual sign on most diverse situations. Cards like Yes, NO, Abstention we didn't use maybe because the team get used to talk and make quick calls about stuff that happed, I din't miss using this card but maybe I'm missing something here, anyway the team have all cards and nobody use this 3 ones so I think we're OK about it.
