Hello world! This is a New Migration Server

Welcome to WordPress. This is your first post on a new server. Edit or delete it, then start writing!

Probably you have noticed that tagline when first installing a WordPress blog on your own or creating a new blog under WordPress.com domain. Welcome to WordPress.

Yes, this blog just migrated on September 2017 from my old hosting, OpenShift server from RedHat. Previously I was running this blog and its component from the OpenShift Cloud by RedHat. If you have read my few first post about the technology behind this blog, you probably know that OpenShift was giving free “cartridge” or free space instance inside their AWS server as a container.

Unfortunately, after OpenShift version 3 launched in September, as I was running on OpenShift version 2, the version was going to decommission. Exactly on 30 September 2017, the version 2 no longer be accessible and all customers need to migrate their account to the new version. But the problem with this plan, their basic plan need the website owner to turn off their instance around 18 hours after 72 hours of runs (https://www.openshift.com/pricing/index.html). This doesn’t make sense if you had an OpenShift version 2 that was giving you free and unrestricted uptime unless you have very minimal traffic.

Before I do the new migration server, I was comparing few other options such as Heroku, AppFog, and other PaaS out there, but unfortunately, Continue reading “Hello world! This is a New Migration Server”

Application Artificial Intelligence using Machine Learning

Artificial Intelligence using Machine Learning.

Artificial intelligence is not a new technology. Everything is now based on artificial intelligence. From shopping related products on Amazon, Google Maps, Waze, even getting an Uber everything is using artificial intelligence to make it smarter, easier and enhance user experience.

The base technology behind an artificial intelligence is machine learning. The technology is trained to learn pattern based on some test data. Then based on it, a new data used for predicting the future. There is a video made by Google developers to explain in further.

In this post, I will describe few tools/libraries commonly used for machine learning.

Tensor Flow
TensorFlow™ is an open source software library for numerical computation using data flow graphs. Nodes in the graph represent mathematical operations, while the graph edges represent the multidimensional data arrays (tensors) communicated between them.
More information https://www.tensorflow.org/

Apache Spark MLib
Apache Spark MLib is one of the top Apache projects which is capable of doing data streaming. It is a fast and general-purpose cluster computing system. In addition to it, Apache Spark has a special machine learning library called MLib.

IBM z/OS + Watson
IBM Watson Analytics is a smart data analysis and visualisation service on the cloud that helps just about anyone quickly discover patterns and meanings in their data – all on their own.

Weka
One of a simple library for machine learning is Weka. Weka is a collection of machine learning algorithms for data mining tasks. The algorithms can either be applied directly to a dataset or called from your own Java code. Weka contains tools for data pre-processing, classification, regression, clustering, association rules, and visualisation.

In next blog post, I will elaborate more on the specific details for each library.

A New Journey in Malaysia – What I Feel About This

It’s been a long time since my last post on January 2017. This is the story of my new journey in Malaysia.

I was officially moved and resigned from my old company on 31st December 2016. During my last two weeks, I have been working to do some knowledge exchange to my new teammate (which technically replacing me). A lot of stuff need to be done at that time. From explained to them how to use our corporate systems, what we have done so far, what was difficulties, unresolved issues and so on (Probably you understand if you ever faced the same condition before as what I did).

My ex is a great company. Truly. But I think I need to move on.

In the end, in every a story, there are something to learn for. This is my story and what I have learned in my journey in past two and half year with my ex. 😉
