The new system is at version 0.1 right now, with basic functionality working. The system is split into groups, so while one server runs separate departments can run a “group” and have their employees under there. Once a user is given privileges to one group in the system, when that user logins in, that group will automatically come up.
The old system had a html page that managers could edit, to give announcements to workers. This was a bit of a tedious process to go in and manually edit these pages, now there is a field for the manager of each group to drop html to edit their page. The system has two levels of accounts and privileges, there is the privilege within a group, and the privilege for the entire system. While a user can be administrator of a group and edit their group, they may not have administrative rights over the entire server. By having administrative rights to the entire server, a user can change the splash page before a user is logged on, or create new groups in the system.
The system allows for templates to be made of weeks, so if a student worker works the same hours every week, then they can save it and deploy it easily. I am working on integrating email reminders by using a .Net application that integrates with MySQL. By having the application read who has yet to enter logs this pay period I can use the students CAS login to get their email.
Below are some photos of the system, and it is all open source at the attached link.
I am back at RPI, finishing up my degree. Recently I have been working on hour tracking software for several departments at RPI.
Recently I have run into a minor annoyance where I am in the command line in Windows and need to elevate a command or program so that I can do a administrative task. (Such as moving a file to the system32 folder), the normal solution is to right click command line short cut and “Run as Administrator”. While that works its not fast, I’m sure there are other solutions out there, but I wanted to quickly build on in .Net. I did this a while ago for Vista and called it elev, but never saved it and since I am trying to make the transition between Windows and Linux easier I called it sudo.
All you do is put this in your %windir%\system32\ folder, and then at the command line type “sudo cmd” or whatever command you want. Commands like “dir” are actually part of cmd not a separate file called so “sudo dir” wont show anything, it will output the .Net error.

I wrote a quick little program to solve a problem for me. If you have two algorithms in webpages and want to benchmark them to see the difference, the program will work for you. You add the the below code to a PHP page, or do he same thing in other languages, then the app will run as many times as you tell it to and find the result in time. To lower the time it takes to get a result, you can up the thread count. Averages are not returned till all threads return information.
Start of PHP Page:
$time = microtime(TRUE);
End of page:
echo "seconds " . (microtime(TRUE) - $time);
Recently I was told “I can’t remember anyone getting OpenAFS to work on their own”, by a staffer at my school. I took it on myself then to figure out how to get this working for students. And in the end I wrote an app that will automatically download and install the AFS client, then configure drives for you. This was an experiment in threading and using WPF instead of Windows Forms.
First the app goes and downloads the OpenAFS client, if it is a 64 bit machine it grabs the 32 bit tools first then the client. While downloading and installing these things it connects via SSH to a school server to get the location of the user’s home folder as well as verify the credentials given.
Once installation is complete the program runs ‘klog’, this goes to the AFS server and requests tokens in the cluster using the credentials given earlier. Once we are past the installing point all these actions need to be run on the campus network. When the program starts it tries to ping a couple internal servers, if it can hit more than half of them in under 75 milliseconds then it considers itself on campus; if it thinks it’s off campus, then it notifies the user. One small problem with the first release is sometimes this system gets confused by vpn taking slightly longer.
Now that we have working token the system recommends drive letters that are not in use as well as AFS spaces to mount including the users folder and ‘dept’ to start. The configure button will activate these drives, they are not set to persistent at this time.

I needed a SSH framework for a program I am writing for my school. There are quite a few out there for .Net but I ended up going with the one from http://sshnet.codeplex.com. It requires .Net 3.5 or 4.0, but its ease of use makes this not a problem. Below is a example of code using the pre-built binary for .Net 3.5, this code connects to a SSH server, then runs a command and stores the result in a string called ‘temp_holding’.
Renci.SshNet.SshClient MysshClient = new Renci.SshNet.SshClient(server, username, password); //these are varibles of strings
//Something in here failed
Renci.SshNet.SshCommand MyRanCommand = MysshClient.RunCommand(“pwd”);
string temp_holding = MyRanCommand.Result;
Feel free to give feed back or use this, open source fun.
I was going through all my photos the other day when I realized there were a lot of duplicates, I wanted to find a easy program that could find these. After some searching, I found a bunch of programs that worked, yet cost a good amount, and I didn’t see any that had the feature set I was looking for; including a list of the files which I could save, a method to move the duplicates to another folder, and customization. Along with most importantly I wanted a FREE duplicate file finder, not expensive one that did a simple job. So I made my own. This is version v0.01, the main function works well, the main interface is meh, but it works. More updates and features to come, but for one days work its good. Also I am going to be opening up some software in the future, including this one when its closer to completion. If you have any features you think of leave a comment, I was thinking about adding a preview for photos, music and maybe video. Saving, loading logs, delete all but one copy of file, not bad interface…
