Publishing to Maven Central

September 5, 2016 Leave a comment

You can follow the tutorial for publishing your library from this following series of youtube videos. You will need to request via Sonatype JIRA and wait for approval. It’s explained in the series.

However if you want the easiest way you can leverage using bitbucket pipeline. You can see the step by step on how to do that from this tutorial. It’s still in beta phase but looks promising. You should give it a try and ask for the trial. Yes, you need to request the trial first and wait for the approval.

The missing part on the tutorial above is on how to generate the key. Here’s how you can do that in Windows machine.

  1. Download the gnugpg for windows here
  2. Setup the key for signing
    1. Generate the key
      gpg –gen-key
    2. Find the list of the key to find the id
      gpg2 –list-keys
      gpg2 –list-secret-keys

      Let’s say that the id is 4C7CF393. We will use this key in the subsequent step.

    3. Publish the public key
      gpg2 –keyserver hkp:// –send-keys 4C7CF393
    4. Export the private key
      gpg -a –export-secret-key 4C7CF393 > private-key.gpg
    5. Donlot for encryption
    6. Add the binaries to your PATH environment variables
    7. Encrypt the key
      openssl aes-256-cbc -in private-key.gpg -out private-key.gpg.enc -pass pass:somesecretpwd
  3. Upload that key to your repository. You can base your repository by copying this repository and replacing the private key there.
  4. Copy your source code and etc there.
  5. Replace the configuration for username and password by looking at README from this repository
  6. Edit the pom.xml so it publish your library
  7. You can follow the rest of the tutorial from this

Happy Publishing !

Geekseat is my new home – Home for Geeks

August 31, 2016 2 comments

Geekseat is a agile soft company that locate in Bandung. My friends and mentee works there so i think why pay them a visit in their own base camp while i can. I got nothing to do besides of job hunting for jobless programmer.:)

I’m utterly shocked to the max

There are a couple unique things that you will find out in Geekseat. Its not something you can see in regular company in Indonesia.Well, I might be bias but I have a lots of friends and working on software industry for almost 8 years.

This culture still amaze me. How could they work like this? Is this even possible.

After visiting them I’m doing my research about the nature of geeks work and personality. It’s really different from other profession. I found a good book for this one. This book is really recommended for geek leaders or manager or whatever title is popular right now.




Here’s a unique culture in Geekseat.


  1. No dress code. You can wear anything to office.
  2. You can work anywhere remotely.
  3. The office is cleared at 4 pm.
  4. Family culture is really the key.
  5. No manager. Only a leader.
  6. No gap between junior and senior
  7. Agile is in its blood. Well it’s agile soft development in his name. What do you expect.
  8. Say no to overtime. Agile is all about sustainable pace.
  9. Interview process. Everyone is a family right from the beginning. Geekseat treat the candidate as customer. We never judge people. We educate right from beginning.
  10. Training process. We never leave the junior or newcomer going point blank without any direction. We provide training from the basic algorithm to advanced enterprise integration pattern.
  11. One person only focus on one project. We never overload the family member


I also read a book by Paul Sloane Leader’s guide to lateral thinking. The book mention that kind of organization called spaghetti. This model of organization produce a lot of productivity and creativity. Because geeks don’t respect the hierarchy structure. Power can’t control geeks !



Geeks can only be effective if leading by geeks. Because they respect technical knowledge. Behavior is irrelevant with productivity.


So previously I have been crafted this manifesto called Geeks Manifesto. Drum roll….








So if you think you are geeks and doesn’t feel happy. You should asked yourself. Are you on the right home?

So I’m proudly announce that starting today I’m joining Geekseat as Technical Expert.

The only thing i need to prepare is short pants. So i’m not looking like an alien when using my usual office dress code.


Nuff said.


Rock on !
