weird myeclipse

I got this weird problem with myeclipse that after installing it eclipse just turned out no responding. Then system files and directories began to disappear after I forced eclipse terminated, which resulted in system boot failure when the machine is restarted. I got the myeclipse from their official site... I don't know if there was any virus... anyway, fedora reinstalled.

I started to read some codes of RDAHMM. I think I can begin from the function for analysis of svn diff output before understanding the detailed flows.

The mid-term exams are coming next week, so probably I'll get little time with the project... But the courses are just getting more interesting, hehe.

Got the first problem to solve

Zhigang came on Wednesday, and we had a talk together with Marlon. They told me some details about the code and services in QuakeSim, and about the new function of running RDAHMM everyday on archived data.

I belive the implementation of this new function will take no long once I am familiar with both the technologies and the services and structures of QuakeSim. So I think I'll first do some code-reading of the services, and learn about web services technology on the way.

I am also looking forward to seeing interesting results of the new function, and learning something about the classification algorithms used by RDAHMM may also be fun.

Getting familiar with QuakeSim2

After solving a problem with downloading maven, I got QuakeSim2 built and installed.

I changed the google key in env.sh before building the project, but after that there are still several jsps that should be modified with the new google key. I don't know if there are other ways to do so, but things would be prettier if we can get this done automatically. I will talk about this with Zhigang when he comes.

I read two papers about QuakeSim. Nothing about bandwidth constraints in the development of QuakeSim is mentioned in these two papers. If QuakeSim is not facing this problem, the bandwidth bottle neck of the satellite channel should be one of the key differences between PolarGrid and QuakeSim.

not an easy start...

To get started with QuakeSim2, I first tried to install linux; but it turned out that things just don't go smoothly.

Firstly the partition magic software failed while I tried to merge f:\ driver to e:\ to set up space for linux, and the result was just as bad as getting f:\ lost. I tried to recover some files with easy recovery, and fortunately Qi told me that there has been nothing important under that drive.

Then the dvd-rom turned out unable to read the borrowed fedora disk.

So one thing led to another, I ended up installing fedora from iso image on vmware.

The operating system course is heavy, but I get a chance to get familiar with linux and svn from the experience with the assignments. So things should be easier after this first step.

Another problem is that I always get this "301 Moved" Error from svn when trying to check out the codes from source forge, either with the svn clinet on the servers of the cs department, or on the newly installed fedora, or in the windows environment. I did some search about this, and it seems that there might be some problems with the configuration of the server. I will talk to Malon about this.

God bless us all, and God bless QuakeSim.
