phun – make physics study like game.

liduan — Tue, 18 Mar 2008 22:02:06 +0000

If you just watch the following video without my introduction. Probably you will think this is a 2D game or new interesting paint. But, in fact. It is a software of 2D physics sandbox.

Video

Official introduction is:

Phun is a Master of Science Thesis by Computing Science student Emil Ernerfeldt for supervisor Kenneth Bodin at VRLab, Umeå University. The solver is based on work by Claude Lacoursière

Phun is meant to be a playground where people can be creative. It can also be used as an educational tool to learn about physics concepts such as restitution and friction.

Phun was coded in C++ using OpenGL, GLEW, SDL (for window management), SDL_image (for reading images) and boost, including boost_filesystem. Everything was coded by Emil Ernerfeldt, including the physics engine and user interface.

In my opinion. Phun is a software that can make physics study more friendly and easy. It can used to test physics event in the computer without physical laboratory. Phun support two kind of platform – windows and linux. Currently ,Version 3.12 of phun is available in the official website. Students have built a online wiki and forum systems.

oracle 10g in xp and vista

liduan — Sun, 04 Nov 2007 20:23:42 +0000

forgetting about linux. I just build a VMware machine for oracle. a windows XP is running in the VMware machine.

A flash movie show how oracle 10g better.

all code for table building:

Oracle in linux

liduan — Sat, 03 Nov 2007 22:50:14 +0000

I have spended a lot of time for installation Oracle in Linux. But it still fail. I use openSUsE 10.2. many people successfully install oracle in the opensuse10.3. I don’t know where is problem. error code is OUI-25031. main problem is net configuration assistant failed.

Now, I only install oracle 10g in a VMware machine. this machine is use windows XP. and a oracle clinet have been installed in my vista machine. the database sql code can be downloaded in webct.
