Articles and Publications

Co-Founder and Editor-in-Chief

Mon, 01 Jan 2018 07:30:07 +0700

Co-founder and Editor-in-Chief of Easyread, a Medium publication that curates articles by Indonesian engineers, written in English or Bahasa Indonesia.

Publication: https://medium.com/easyread

About the publication

Easyread aims to explain complex software engineering topics in a way engineers can easily understand. Many articles already exist online, but some Indonesian engineers find them hard to follow because the language is too difficult.

To address this, we look for articles written from engineers’ own perspectives and experience. Personal experience is a valuable lesson for others.

Contributing Writer

Sat, 01 Jul 2017 07:30:07 +0700

Contributing writer for Hackernoon, publishing articles on software engineering.

Profile: https://hackernoon.com/u/imantumorang

Reading older articles

Since Hackernoon moved to its own independent platform, some older articles have lost code highlighting and images, and a few have rendering bugs. If one of my Hackernoon articles does not display correctly, change the base URL to Medium.

For example:

https://hackernoon.com/today-i-learned-pass-by-reference-on-interface-parameter-in-golang-35ee8d8a848e

Change into:

https://medium.com/@imantumorang/today-i-learned-pass-by-reference-on-interface-parameter-in-golang-35ee8d8a848e

This opens the Medium version of the article, which has better code highlighting and all of its images.
