As a little children, I had been finding my joy in my collections of toys. Then as I grew up to a teenager, finding my joy in collections of comic books, game cards collection. Then in adulthood, joy in accumulation of wealth/possessions. At first glance, it seems much of joy to be able to accumulate all this things, but we didn't realised that we had became slaves to things that we are gathering. Take example of a young man, whom had committed to purchase a luxury car with a loan that he commits to pay for the next 10 years. He didn't just commit to pay the monthly commitment of the car loan amount, he also unknowingly commit his time/money to maintain the car to keep it clean, polished nicely, servicing and sometimes to repair it due to accidents or car parts worn out. As it turns out, this man had made himself a slave to this purchase of luxury car. We lived in a society that sometimes took pride in the things we possess, to impress other people of the belongings we had or...

This hymm with the theme of Sovereign Grace was inspired from the book 1 Samuel in which Prophet Samuel in 1 Samuel 7:12, took a stone and called its name Ebenezer and said "Till now the LORD has helped us".  In the context of 1 Samuel(1 Samuel 4-7), Israel has been defeated against Philistine as Israel people has taken for granted the grace from God in which God delivered them from slavery at Egypt and all the way to guide them to the promised land but they still sinned against the LORD by idol worshipping Baals and Ashtaroth. The Israelites has thought that by the act of bringing the ark of God to the war will bring them victory against Philistine, but God knows this hideous thought of theirs and bring them defeat instead. As the Israelites was defeated, the ark of God was taken captive by the Philistine, and the ark was brought to the house of Dagon and placed next to the ...

Simplex is one of the powerful algorithm to solve linear programming problems. With simplex, we can maximise or minimise objective function with the given list of constraint. public class Simplex { private double[][] tableaux; // tableaux private int numberOfConstraints; // number of constraints private int numberOfOriginalVariables; // number of original variables private boolean maximizeOrMinimize; private static final boolean MAXIMIZE = true; private static final boolean MINIMIZE = false; private int[] basis; // basis[i] = basic variable corresponding to row i public Simplex(double[][] tableaux, int numberOfConstraint, int numberOfOriginalVariable, boolean maximizeOrMinimize) { this.maximizeOrMinimize = maximizeOrMinimize; this.numberOfConstraints = numberOfConstraint; this.numberOfOriginalVariables = numberOfOriginalVariable; this.tableaux = tableaux; basis = new int[numberOfConstraints]; for (int i = 0; i < ...
