Just I why to share with you. I know that every person has the personal preferences and it´s good. I don't want to change an opinion just to share what's works to me.

My first time listening a podcast?

If I remember well was on last decade on 2009 was a CBN radio podcast made by Juca Kfouri and was about soccer, a common topic in Brazil.
In addition, I had no music on my iPhone and Spotify had not yet been released.

Why take a Java certification?

Luiz Gustavo Costa — Sun, 26 Jul 2020 14:05:45 +0000

This post is about my experience with Java Certifications and I´m assuming that content could be applied in other areas/certifications.

How tough it is?
My certifications
Final words

Why

These were my "why" to try and take some certifications

Better understanding of technology
Enhance my developer skills
Have a better CV
In a interview you can go deeply in some topics and show what you know about.
Write articles and participate on discussion topics about technologies and not only be a reader.

How tough it is?

Back in time, more precisely in 2006 was very tough to take maybe because was my first the Java Programmer 1.4 and was very anxious and had afraid to fail, it could be happened.
Have time to study and sometimes create brain muscle to study every or 5 times a week at least.
Try using great mocks, because on my last try I bought one mock that give a bunch of wrong answers and I fail on the test.
Fail is normal more than I thought, the thing to do is have a time for you review the failed topics, study be calm and schedule another test.

My certifications

All my certifications are related with Java and check out below:

Year	Name
2015	Oracle Certified Master, Java EE 6 Enterprise Architect
2008	Sun Certified Enterprise Architect for Java Platform EE 1.3
2007	Sun Certified Business Component Developer for the Java Platforn, EE 1.3
2007	Sun Certified Web Component Developer for the Java Platform, EE 1.4
2005	Sun Certified Java Programmer 1.4

Final words

Do it by yourself because in my case the certifications having me help until nowadays to thing how to solve problem no matter how old I took.

1 - What is the best name?
2 - How to record

4 - Where I could find sound effects?
5 - Is there any free host?

1 - What is the best name?

This is the first but if you don't have any name for now, no problem you should have before publish your podcast.
A time ago I listened a podcast and they said to no add the name podcast or even cast as a name, but I disagree because the name should be unique having or not podcast or cast.

2 - How to record?

On my podcast I use to record on Zoom application, since I record with some friends, but if you record alone this record could be using any software as GarageBand.

3 - How to edit?

To edit sometimes the best part of podcast I use GarageBand
if you've a MacBook.
I look for other softwares but defenetively the GarageBand for me until today is the best.

4 - Where I could find sound effects?

The sound effects could be added inside the GarageBand or import sounds from iMovie or even search on the internet for some track such as https://movie-sounds.org/

5 - Is there any free host?

Yes, for instance https://www.podcasts.com is a site where you use as a host server to share you podcast to others channels such as Spotify, Apple, Google and son on.

6 - Share you podcast

As said on item before some big players are Spotify, Apple, Google and TuneIn, so once you've one host to your podcast, it's time to share your feed to players.

Have a good podcast a good weekend, btw my podcast is https://open.spotify.com/show/1A9vHJkLIMxj6t8lHZwqzB?si=Rf0PEaJLQAy1Z1wWkhIf_Q

How bad my computer was?

My computer is an old MacBook Pro from 2011, yes a long time ago :) and I came with 4gb of memory not bad talking about 9 years ago and about 4 years I updated to 16 gb.

So past the time I felt some difficulties to open or even work with my IDE and using a software to analyze I/O I saw the numbers bellow.

My options

The first but the more expensive is: Go to apple's site choose the best configuration and finish the purchase paying a lot of money :(.
The second be patient with the machine :(.
The last was if I change the disk since a ssd disk is faster than the actual :) ?

What I choose?

I choose the last option and I had to bought the ssd and more tools such as

SSD disc
SSD to USB cable to copy the data
Precision Screwdriver
Antistatic wrist strap with ESD protection + grounding cable + mat set
16 hours to execute the backup from HDD to SDD
30 min to open / close the laptop

Result

After the little journey to buy the things and wait the copy to SSD now the laptop has a better performance and now I can open my IDE, browsers etc

Why

Use a template project structure in order to speed up your project definition such as packages, dependencies and relationship between classes.

How to build

To build an archetype you should follow the rules

The packing of project should be maven-archetype
Create a file archetype-metadata.xml under the folder src/main/resources/META-INF/maven.
This file is responsible to move the files classes, folders etc.
The folder src/main/resources/archetype-resources should have all files to be generated by this archetype.

Structure

Below look the structure desired

After open the project generated you can check the classes packages and so on

Benefits

The benefits of using a archetype as said before is speed up your project creation but also to maintain the projects with the same structure and avoid copy and paste of files.

How to run?

use the maven to build your archetype and for that execute the command

mvn instal

for instance
Once your template is created it's time to create your project with the template

mvn archetype:generate -DgroupId=com.mynewcompany -DartifactId=new-project -DarchetypeGroupId={from your archetype project} -DarchetypeArtifactId={from your archetype project}
