Touchy-Feely Version I’ve been using this word a lot at work lately. Framework. I’m sure they thought it at school what a framework is, but I was never really able to put it in words. Well, I was never good with words anyways (almost got F on multiple English University courses). But after in the… Continue reading What is a Framework? And good Frameworks
Open Source Project Branching Model
Introduction This document describes how SonarK works with the upstream project it is forked from, which is Kibana. This is in an attempt to make the upgrading process more manageable by a human being. Problems With “Bulk Upgrade” Up until the writing of this document, upgrades have been performed once every few months when we… Continue reading Open Source Project Branching Model
Value overflows with <input type=”number”/>
Problem We recently hit a problem where users pasting large numbers in a <input type=”number”/> (part of a query input box), causing a wrong result. After further investigation, we realized that numbers (integer or floating points) exceeding 2^51 causes problems in Firefox, and probably just a bigger precision would cause problems in chrome. At the… Continue reading Value overflows with <input type=”number”/>
Avoid Re-Running NPM/YARN in CMake targets
Introduction Despite all the webpacks and gulp and whatever build/package system you have in your npm/yarn project, chances are you have cmake that orchestrates your build. In my case, our organization requires project to be built/package by cmake, mainly to simplify our build system. Effectively reducing it to run: git clone <project url> cmake …… Continue reading Avoid Re-Running NPM/YARN in CMake targets
How Open Source Development Differ

Design By Contract And Functional Programming, An Inseparable Pair In Transpilers
For the past 10 months, I am fortunate enough to be assigned to work on a transpiler between elasticsearch and sonar (basically MongoDB syntax with our own proprietary extensions). By creating this transpiler, this allowed our organization to use a proprietary version of Kibana with our MongoDB like database system. This experience has forced me to extract… Continue reading Design By Contract And Functional Programming, An Inseparable Pair In Transpilers
Packaging Huge NodeJS file in RPM
My work involves managing and developing a NodeJS project. Recently, the whole project, including the npm dependencies have reached 1GB. This caused us to keep getting: Unable to create immutable headers After searching around, I found that Software Development at BBC has encountered the same problem and they made a Medium article about it. But… Continue reading Packaging Huge NodeJS file in RPM
Escape to Lake Hayward
A cold damp Sunday morning in my abode. Dark clouds have descended near the sea, blocking the sun. I’ve spent all my Saturday recovering from the hustle and bustle of work and decided to go for a long hike. By browsing the internet, I ended up settling on a 15km hike on Lake Hayward. The… Continue reading Escape to Lake Hayward
Deploying Kibana with Pre-Installed Plugins
Kibana is an open source project. Modifying and developing over it is therfore a natural thing to do. Organizations might want to do it to fit their various specific needs. Although, a developer could dive right in the src/ directory and fiddle with the code immediately, a more proper way of customizing Kibana is through a… Continue reading Deploying Kibana with Pre-Installed Plugins
