In the assignment submission window I can't get any labs or homeworks under the assignments drop down box. All it says when I open it is assignments. What do I do since I can't distinguish what I'm turning in.
Every time I try to load this program into JES, it says that I have a syntax error. Can you tell me why? (I type it exactly as in the lecture notes)
def decreaseRed(picture):
for p in getPixels(picture):
value=getRed(p)
setRed(p,value * 0.5)
Put two more spaces before "value =" and "setRed" lines. Remember that those are a NEW block, so they have to be indented more. Mark Guzdial
I am getting the same response because it is not recognizing the language decreaseRed. That part doesn't highlight purple like it should for some reason.
The only things that highlight purple are the things that are already known to JES, like "getRed". "decreaseRed" is a NEW function that you're teaching JES – it won't ever be purple. Mark Guzdial

Just wondering if we should be able to answer the questions at the end of the chapter? Will the questions be similar to a quiz or test question?
Somewhat similar. You can see past exam review questions on the Hotspots #3 page. Mark Guzdial
My MediaTools doesn't work. I pulled down the MediaTools menu and selected Picture Tool, I selected a picture and clicked OK, and nothing happened. I clicked on the picture I selected and nothing happened. Do I need to do something else or is there something wrong w/my JES?
That's weird–haven't seen that before. How much memory do you have? What operating system are you running? You can also use the MediaTools application on the disk – I'll demonstrate that on Wed. Mark Guzdial
Can you call show() on the picture and get it to open up? Also, are you running JES from the CD, or did you copy it to your hard drive? If you're running from the CD, the Picture Tool won't work. Adam Wilson

If a student is prepared for class- read the material, review/executed the labs, attended class, etc- shouldn't the TA's demonstrate some preparation as well? I know y'all are probably very busy, but certainly, being a TA is voluntary. Please show some effort.

If you have any problems or concerns with your TA, please contact either me, Angela Liang or Prof. Mark Guzdial. Angela Liang

Like Angela said. If you have issues, then please contact me. Most of our TA's weren't assigned until just before recitation – they're trying to get up to speed as quickly as they can. Mark Guzdial

does anyone know of a good free popup blocker that I can download or something. this is getting rediculous. Mark Hilmy
Mozilla.org: download, change the settings to block popups, problem solved.
Thank You. I'll see how it works. Mark Hilmy
My Media Tools doesn't always bring up the picture I tell it to. If I have several named pictures and I choose one from the pull-down menu for mediatools, it opens the mediatools window but usually with the picture I last had open. Help?
This is a known bug with MediaTools. We're working on it and will probably make a new JES available as a download. Mark Guzdial
