Inspiration: the famous fork bomb in the Linux world.Fork bomb::(){:|:&};. It’s like a crazy binary tree that consumes the resources of the system constantly. Fork bomb has an impact size of . The script here can’t do that terrible damage. Read more…
Here is a bash script helps you to rename files *.c.gz to new files *.c. Code snippet: #! /bin/bash cmd1=$(ls |grep c.gz) cmd2=$(ls |grep c.gz |sed ‘s/\.gz//g’) array1=() len1=0 for i in $cmd1; do array1[$len1]=$i len1=$(expr $len1 + 1) done Read more…
Here is a convex object and an origin point outside it. is an arbitrary point in the boundary. Find the farthest point on the boundary along the vector . Name the farthest point . We get a new vector to Read more…

The post shows a way to create 2D grid on screen by VTK. Show it by vtkActor2D because we regard it as a 2D object. Its default coordinate system is viewport which is rendering. So we will have to know Read more…
I created a 2D convex hull and wanted to check whether a point is inside it. If the point is inside the polygon, the neighbor cross product vectors have the same directions. If the point is outside, one vector is Read more…
The post shows how to find 2D convex hull and 3D convex hull from points cloud by VTK. Here are some points on screen, finally I add a specail point that z value is not 0 for test 3D convex Read more…
