I think that this class is going to be great for everyone. It will give us a whole new perspective on computers, the internet, and programs, in general. I am so glad that I am in CS 1315. Prof Guzdial seems like a very energenic person that will get us all motivated to use what we learn throughout our professional careers!
You don't HAVE to say nice things here...

'ho-ho beriberi'
'why is yellow?'
this class is cool!!

Sometimes I get scared
Brittany Selden will be having office hours WeREMOVEDsday, Aug 20th from 11-11:55 in the Student Center on the 2nd floor by the couches.
When I try to open JES after I put it into My Documents I get "To open this file,Windows needs to know who created it." Then it takes to the internet to find out than says it cannot find it. How do I fix whatever I screwed up?

What did you click on "to open JES"? Did you double click the JES.exe file (the one with the Python on it)? What operating system are you running? We didn't test on Windows 95/98. Mark Guzdial

If for any reason running JES.exe does not work, try running JES-console.exe. It's a "compatibility-mode" version and is more likely to run on older Windows versions (ME and older). Adam REMOVED
Where can i find the powerpoint slides to print out?
On the page Syllabus and Lecture Slides-Fall 2003 which appears on the Home page (click Home above). Mark Guzdial

I followed the instructions and installed JES on my computer (Win XP). When I double click the desktop icon to open it, two errors show up: "The system cannot find the file specified" and "Error accessing file/directory: Classes\". When I open JES directly from the CD it works fine. Help?
It means that you didn't get all the files copied from the CD before you tried to start JES, or something went wrong with the copy. Try copying again. Thanks for letting us know that it runs fine from the CD – that's an important clue that tells us that the CD is okay, but it didn't make it your hard disk complete. Mark Guzdial

In JES, why can't I name something like show(makePicture(myfile)) ?
You can – we did that in class. (Assuming that myfile is the path to a file, assigned by saying myfile=r"C:\\Documents and Settings..etc." or myfile=pickAFile().) Mark Guzdial
Why when I type this command into JES, do I get the following error?
play(makesound(C:\\Documents and Settings\\Erica\\My Documents\\My Music\\Aerosmith\\O, Yeah! Ultimate Aerosmith Hits Disc 1\\05 Walk This Way.wma'))
Your code contains at least one syntax error, meaning it is not legal jython.

I think its because if you are using windows you have to put an r"...." around C://Documents etc. thats what he did in class for us. type it in like this play(makesound(r"C:\\Documents and Settings\\Erica\\My Documents\\My Music\\Aerosmith\\O, Yeah! Ultimate Aerosmith Hits Disc 1\\05 Walk This Way.wma"))
Excellent answer! That is correct, but one more problem: Check out the extension. That's a .wma file – Windows Media file. We can only play WAV files. Can Windows Media export a .wma file as a .wav file so that you can use it? QuickTime can do this for some media formats, but I don't know about .wma. Mark Guzdial
I just tried to turn in Lab2 in JES. I got this error "An unexpected error has occurred in the turnin process. It is unlikely that the program turnin has failed. Please check your Student ID and Server inside of JES’s settings and resubmit the assignment." I checked and I put in my gt# and name correctly. Please help!
Yeah, I got that same message. I checked my settings and it didnt have anyhting about a server in the settings. Everything else is correct though.
Student/TA assignments have not been set yet so you won't be able to turn in Lab2 until they're set. We will make an announcement once everyone has been assigned a TA. Student56
When I tried to install Quicktime for Java an error came up that said "couldn't establish a connection with 'Apple Public Server'. What does this mean and what do I need to do to make it work?
I just want to know how I can load up JES to 64MB RAM computer becuase it takes alot of time. Can any body help me please?
I 've got my answer. Thank you
When we spellcheck the Word document for Lab 2, are we supposed to let Word change the text at its every suggestion?
Spellcheck should pick up only the words that need to be changed, so technically, yes. Use your common sense when it says to change things, though, and actually read what it says. Kelly Farrell
I will NOT be holding office hours this Tuesday, August 26. Something has come up. Email me if you need help, gte960t@prism.gatech.edu! Kelly Farrell
In Lab 2 on example1 is anyone having trouble getting the sound, everytime I do it, it says to look at line 5 which is the file = makeSound part. Any thoughts?
If I'm correct in what line you are talking about, this line should actually read 
sound=makeSound(file)
There is no line that contains the excerpt that you put above. Lauren Biddle
I'm having the same problem as above. I pasted the code into JES with the filename to the sound and I put the r in front of the file name. When i try to run it, I get the response:
There is no file at C:\JES\mediasources\Elliot-hello.wav
An error occurred attempting to pass an argument to a function.
Please check line 5 of C:\My Documents\lab2a.py
You haven't actually specified the filename correctly. Did you remember the quotes, too? JES is saying that it can't find the file you're telling it to make into a sound. Mark Guzdial

To address the comments in the Soapbox:
  • Great idea about the Who's Who plus sign, but on the other hand, I want students to practice editing and for issues of deletion come up. It's easily fixed, and it's a good lesson.
  • JES can't open up MIDI files with makeSound, but we will play MIDI later in the class. Good catch!

I don't know how to get JES to show up in the list of all programs in the Start menu (I'm running XP, and I'm not used to Windows). I put the folder in Program Files and it's still not there. Any advice, or do I just have to get used to it?
I don't know how to get programs in the Start menu. You're right – though I use JES a lot, it never shows up there. I have no idea why. Perhaps we need to sacrifice a goat to Bill Gates...:-) Mark Guzdial
