Linux Power Terminal with Oh My Zsh and Powerlevel9k

As Developers we spend lots of time using Linux terminal. Today I will show my set of customizations I'm currently using.

The terminal setup we will see is awesome because it makes your life easier using git and also display useful information about Linux.

I will show how to configure Oh My Zsh with Needfonts, Powerlevel9k theme and ruby colors on Gnome Ubuntu 17.04.

Tools that we will use:

Global Gradle Config for Remote Debug and IDE support

Image
Gradle right now is the standard tool for Java builds. Before gradle, pretty much everybody was using maven.

Working with cloud computing very often we need do remote debugging. In this blog post, I will show how to configure remote debugging for all your gradle projects.  The nice thing about the approach I will show is that you don't need to change your build.gradle files since we will do it as a global config this will be valid for all.

We also will setup configs for Eclipse and IntelliJ IDE support in the same file. Since we will configure remote debug you need to keep in mind that debug port need to be open in all security groups and firewalls in order to work.  Keep in mind remote debug is slow especially with Amazon.

We will open port 9009, but you can change the port if you like. This config works with Jetty and also with Java main classes as well.





Dynomite and RocksDB running on Docker

Dynomite is a kick ass cluster/proxy solution that provides high availability and strong consistent to databases. Dynomite was created and battle tested by Netflix using Memcached and Redis as primary store backend.

RocksDB it's a Facebook Embedded Key/Value store which is growing up a lot because of his incredible high performance and low latency.

For this blog post, I will show some simple project I create for the developers to get started with Dynomite and RocksDB together. This project uses docker and creates a Dynomite cluster using RocksDB as backend.

Let's get started...




Cool Retro Terminal

Image
I often don't blog about this kind of stuff. Yesterday I friend of mine showed me this awesome project called cool-retro-term.

When you work with Cloud Computing and DevOps Engineering you spend lots of time on the black screen testing things on the cloud.  When I saw this project I got very excited because it brings some nostalgy back to my life. To be 100% clearI'm not that old as my friend :-) However I share his joy into this retro terminals. This also reminds me some old games like Fallout 1. I just this is pure fun so I'm sharing here with you guys some screenshots and also how to run on Gnome Ubuntu 17.04.



Configure a Cassandra 2.x Cluster on EC2

Image
Cassandra is a kick ass NoSQL Database that guarantees strong consistency.  Inspired by Amazon Dynamo paper Cassandra can deliver high availability and strong consistency.  Battle tested by companies like Apple, eBay, Netflix, Github, Nasa and several others. For this blog post, I will show how to setup a simple Cassandra cluster. This setup is for development purpose and it's not ready for production.
