RPM deploy in Neuxs

Nexus is a repository manager solution for Java. Similar to Archiva and Artifactory. If you are a Java developer probably you are familiar with this kind of solutions. Nexus is useful because acts like a proxy then you can improve download speed because you have a central cache and you have your deploys and binaries there.

There is feature is really cool on the DevOps context makes lots of sense is the RPM feature. Basically you are allowed to deploy RPM in Nexus, Artifactory has a similar feature too. This is very useful because sometimes you need to pack things that are not JARS and this is very useful to the operations point of view. So In this post I will show how to install Nexus on Linux and how to deploy an RPM in Nexus is pretty easy and there are more than one to do this.

There are 2 ways to deploy on Nexus. You can use Maven(method1) and Curl(method 2 and 3). If you use maven you need make sure maven ins on your PATH and you added credentials for Nexus on the settings.xml file. That's it.

Cheers,

Having fun with Zig Language

Image
Zig is a general-purpose language created in 2016 by Andrew Kelly .  Zig aims to fix the issues C language has while being pragmatic and simple at the same time. Zig really shines as being simple by not having any hidden control flows, not having hidden memory allocations, no pre-processors, and no macros. Basically, it's one language and one language only. Since pre-processors and macros can get really complex and become their own universe. Sure it's not the Zig Philosophy.  Zig Compiler(Zig cc) also is a C compiler, and the interoperability from C to Zig is very good. Clearly, we can see influence from other languages like Go and Rust; however, Zig is pretty unique and different from Go and Rust.  Zig is fast. Zig is perfect for system programming. I bet we will see a lot of solutions being built in Zig. As a languages aficionado, I like to learn at least one language per year and sometimes more; Zig was my 2021 pick, did not regret it. Even if you dont use all language...

C Unit Testing with Check

Image
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.

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.
