The Ninja Path

Description

Given the specific parameters (size, wall, start and target), you should build a virtual block map. If the size is 10, then it will be a 10x10 blocks map. Each block is numbered sequentially from left to right, then top to bottom. The initial value for this sequence is 1.

If the size value is 6, then the map will be like this,

Rewriting The IRGSH

The reasons behind my decision to rewrite IRGSH are ranged from personal motivation to BlankOn project direction.

After Uluwatu released, a hard disk died in one of BlankOn development server. Unfortunately, the machine is the important one. The hard disk contains IRGSH, the backbone of BlankOn Linux development. The fortunate side is this happened after Uluwatu released. A year before this incident, Estu and I have tried to put IRGSH into production from scratch and it is really hard to do so. IRGSH was written in Python 2.6.x and it depends on some old and deprecated libraries. Even one of them (in a specific version, respectively) is no longer exist on the internet. A real dependency hell. It's hard to deploy IRGSH in a modern operating system and it keeps alynne.blankonlinux.or.id from a system upgrade. The IRGSH was also very modular but combining them into a working distributed cluster takes time and quite steep learning curve. We still need to prepare a lot of things before doing that.
