Lab 5

Got questions? We got answers! (We hope! :-)

Lab 1

I downloaded the firewalls that were listed on this assignment, but when I did, my computer stopped working. OIT came and fixed it. I already had an updated Norton Anti-Virus on my computer and apparently when I downloaded MacAdoo (sp.?), the two began fighting each other. Now my computer is fine, and I prefer Norton Anti-Virus so I am going to stick with it. I hope that is okay for this class (or is it?).
Thanks.

Yes. This is fine. If you already have a firewall on your computer, skip the downloading a firewall section of the assignment, and follow the instructions for if you don't have a virus. Go to the website listed. Pick one and write about it. Do NOT (as you unfortunatly learned the hard way) install two firewalls on your computer. They do fight and it's not pretty. Kelly Lyons

i have a router and i downloaded the personal firewall software and it is telling me that my ip address for my router is an intruder. my question is should i trust and accept my router's ip address? how do i configure my router to do the same thing the software does?

If you are sure it is your router's IP address, then yes you should be able to trust it. For more specific questions about things like this, you should talk to OIT or resnet as they know more about such things than I do. Kelly Lyons

Should the virus that I choose be on the most recent top ten list (July 2005) or should I just choose from the 2002 list or does it not matter? Thanks!

Any of them is fine. Kelly Lyons

The RealSecure Desktop formerly offered at OIT is now ProventialStudent.

I didn't put asterisks by my name the first time I tried making my page, now I don't see my name in alphabetical order. How do I fix this?

The alphabetizing is done manually by one of the TAs. Do not worry if yours is still not alphabetized. Just make sure that you did put asktrisks by your name at least one of the times you added it since you need to do this to make a page. Kelly Lyons

If you still don't see your name alphabatized and if it's not listed at the bottom of the page, you may want to add your name (with astericks) again at the bottom Amanda Bennett

Yes, I am an idiot with computers and I am trying to create my CoWeb personal page and I cant get my name to go uinder the W section in the alphabet.

The alphabetizing is done manually by one of the TAs. When you add your name, it should appear at the very bottom of the page. This is normal. Do not worry about the alphabetical part. That will be done later Kelly Lyons

Do I have to get rid of my Windows firewall before downloading the Realsecure?

If you would like the Realsecure instead, yes you should get rid of the other one first. However, you can also just keep the firewall you have as this will be much simpler and the firewall that comes with Windows will work perfectly fine. Kelly Lyons

Just wanted to let you know kelly that myself, Joseph White, is on the Who's Who list twice once as Joseph white and the other as Joseph A. White. Also how are the labs graded. For example like would me putting my name twice on the board deduct from my grade. Thanks for the time.

It's fine if you're on there twice. You might want to make sure there's the correct information on both pages though, since you don't know which one your TA will look at. If you want one of them removed, let a TA know and we can do it for you. Amanda Bennett

Give the writeup in the email that you will send Kelly Lyons

Is there any way I can be sure my email have been sent? I am using Mac Mail and am not sure if the email went through. Farah Amir

There is no way for you to tell. Try again if you need to. Multiple submissions are okay. Amanda Bennett

I do not have Outlook Express on my computer but Microsoft Office Outlook. Is this ok to use for Lab 1??

Yes, as long as it is set up correctly. Amanda Bennett

I was looking at the Lab 1 turn in page and someone changed it and I was wondering if we were going to be graded baDLY BECAUSE OR GT NUMBERS NO LONGER LINE UP WITH OUR NAMES

Don't worry about that. You'll still get credit as long as your information is on the page somewhere. I'm trying to fix it right now. Kelly Lyons

I am having problems with configuring RealSecure Desktop.

What problems? It's hard to help without specifics. I would also suggest asking OIT since they are the supporters of the software. They would be more able to help with the installation. Kelly Lyons

I have completed the Intro to JES portion, but when I execute example2() (after using the writeTo function) the waikiki picture comes up again and I am not prompted to select a different picture. Any suggestions?

Lab 2

I am having trouble saving the example2 picture in a designated area...i dont know what the problem is

gtg551x

Make sure that the filepath that you are entering in the writePictureTo function exists on your computer. Kelly Lyons

I can't find my picture either. I've changed the path several times and I still don't know where it is. :( I've checked the spelling and punctuation...What am I missing? Mary Beth Strawn

If you are 100% sure that the filepath is set up correctly and that you're checking the right folder, it's probably best to show your code to a TA in person. Since recitations are starting this week, take your code with you and try flagging your TA down before or after recitation. -Blake O'Hare

I'm getting an error message everytime I try to run JES... I set it up the first time and it worked fine, but I closed it and tried to open it again and it's not working... what do I do?

What error message do you get? It's hard to say what's happening without knowing that. If you can't get anything else to work, try restarting your computer. Amanda Bennett

The error says "The system cannot find the file specified" then I click OK and it says "Error accessing the file/directory:Classes\

You may want to try re-installing JES (from the CoWeb, not the CD). If that doesn't work, then you could have a Java problem and you may have to install a newer version of Java. -Blake O'Hare

I downloaded Jes to my computer and try to open it. It has said loading Jes for about 2 hours now. Should it take that long?

If it takes more than 30 seconds to load, then something has gone seriously wrong. Try the usual fixes: restart computer, re-install JES. If that doesn't work, consult a TA or (if you are feeling brave) re-install Java. -Blake O'Hare

If you have a slow computer, it can take up to 2 minutes to load, so don't worry if yours takes more than 30 seconds. 2 hours is WAY too long however and there is definatly something wrong. Kelly Lyons

I'm at the "retrieve assignment" part of the Lab and I can get to my lab2.doc fine, but my lab2.py won't open, even when i tell my computer to open it through JES. But when I open lab2.py straight through JES its there, but I think its only because its saved to my computer. I've already re-submitted my assignment again, and the same thing happened. What should I do?

This is an issue with JES, not with webwork. JES does not have the ability to open itself when you click on a file. You must open JES itself and then from inside JES open the file to be able to view it in JES. Do not worry. Your assignment should be fine. Kelly Lyons

When i try and save my lab2 for JES, it doesn't save as a JES file or have a ".ply" ending. What am I doing wrong?

You're supposed to add that yourself to the filename when you save it. (And be sure it's .py, not .ply) -Blake O'Hare

whenever I try to download JES into my computer, it keeps downloading as a word document and it looks nothing like what we did in class...what do I do?

Make sure you are downloading the right file. It should read JES.zip If you are still having trouble, get the copy that comes on the CD with the book. Kelly Lyons

Whenever i try to run the program on the second part of the introduction to jes lab
the only thing that happens is this:

"makePicture(filename): There is no file at C:\Documents and
Settings\Owner\Desktop\Jes\JES\waikiki.jpg
An error occurred attempting to pass an argument to a function.
Please check line 3 of C:\Documents and Settings\Owner\My Documents\ex2"

what do i need to do?

It is showing you a path C:\Documents andSettings\Owner\Desktop\Jes\JES\waikiki.jpg and saying that there is no file at that path. Check to make sure that this path is a correct location in your computer and that it is spelled correctly. Kelly Lyons

I have a similar question (might be the same one re-phrased about the retrieve assignment question). When I try and open the .py portion, it also won't let me, my concern is the icon in my Lab2 zip file isn't that little worm fellow... is this for the same reason that JES can't open itself when I click on the file or did I do something else wrong?

The icon doesn't have to be a python. it can be anything. for instance, mine is just a little notepad icon, it depends on what you tell your computer to see it as. It is not the same reason JES can't open itself. JES can't open itself due to the way it was made. Just remember that. Anytime you want to open a *.py file, you need to open JES first and then find the file. Amanda Bennett

After you download JES, you do not want to open the .py file to get JES to run. You need to run the JES.exe file to open JES Kelly Lyons

Is it ok that i stuck JES and my media files in a different folder? the folders are still labeled as 'pictures' and 'sounds'. i know their location, and its easier for me to find them, and they're all there. thanks.!

If you know where the media files are and can find them you should be fine. THere is no exact place where you should put the files just recommendations. Albert d'Heurle

What is "correct" when we are asked to "Resize the box for the ASCII diagram to display correctly"? Rebecca Guertin

Make it big enough so that everything shows up. It should be about a half of a page if it's correcty sized. Kelly Lyons

Why is it that when I save my lab2.py file it doesn't actually show up as a saved file that I can open up, but only as a "py" file that doesn't produce anything on my computer. (The program actually works on my computer to run the images and change the colors in JES, but when I save it in webwork and try to retrieve and run it from the saved file, I don't get anything).

When opening a .py file through JES, you have to first open JES and then open the file through JES. Kelly Lyons

How do you insert the picture ran from the writePictureTo function onto the word document? Do we just take the picture that was created in JES when we performed the writePictureTo function, or is there an actual way that we can somehow type a writePictureTo function up in Word and it will produce that picture. Or do we just insert the same picture from our files on our computers that we used to the writePictureTo function?

When you ran writePictureTo in JES, the picture was saved on your computer. From within Word, you just want to insert that picture that was saved onto your computer into Word. Kelly Lyons

When i go to open JES, it loads up, but all the windows come up greyed out. No text or anything, just grey windows. I reinstalled twice but it still wont show anything. I'm running it on Windows XP home and my computer is top of the line. I dont know whats wrong????

Are you able to type in the window? Are you opening the JES.exe file? Kelly Lyons

The directions for Lab 2 say double space the first three paragraphs in the Word Document. Does this mean double space the gaps between the paragraphs as well?

You can if you'd like. It's not necessary. Kelly Lyons

I have a mac and I am trying to download JES from the web. I can place it in applications but when I try to open it, it asks for me to choose an application in which to open it. I can't find an app that will open it. what do i do?

Make sure you are downloading the mac version of JES. Kelly Lyons

i am. i finally got it to open but it is opening like a word document. The one I downloaded showed up as JES.3.sit. Should I just use the copy I got with the book.

The .sit file is a compressed file. When it downloads, it should unstuff itself leaving a folder in the same directory called JES Folder. The JES that you want to run is in that folder. If it isn't unstuffing it automatically, try ctrl click and see if it's an option. Kelly Lyons

Still getting the greyed-out screen and i cant use the program, yes im loading JES.exe, and no i cant type in the greyed windows. i reinstalled it like 5 times. No luck. What should i do? Labs due tomorrow!

I've never seen an error like that. Does it give any sort of error message? If you have a laptop, I'd suggest bringing it to a TA during their office hours. Otherwise, you can go to a computer in the library and download JES onto that computer for this assignment. Kelly Lyons

I'm having trouble re-adjusting the text in the box for the WORD part because the flow chart left justified so it's all scrunched up on the left. even when i re-seize the text box it won't go back to the original form.

I submitted both parts of the lab on webwork, but I am only able to retrieve the Word Document lab2.doc, not lab2.py . Whenever I click on the lab2.py icon, JES starts to load and then it just quits out of nowhere... I have tried this several times. What should I do?

This question has been answered elsewhere on this page. An answer has also been posted to the announcements page. You must first open JES and then open the file from within JES. This does not mean that your submission is in error. It is a JES issue, not a webwork issue. Kelly Lyons

I am having the exact same problem...what is going on?

See above Kelly Lyons

Should we copy the picture of ourselves in example2() into JES , or can we leave it in the file its currently in?

I'm not sure I understand your question. You need to insert whichever picture you wrote out in example2 into the word document you submit. Kelly Lyons

I had to send my JES part of the lab and my word part of the lab sepaprately because I used a library computer since my computer doesn't have word, and every time I go to retrieve my submission it fails to show both of them. I've sent both of them at least twice if not more, and each time it only shows the one I sent last. Did both get turned in?

No, you must turn in ALL of your files at once in webwork. each time you submit something, it erases your last submission. You can e-mail yourself the document you used for the word part of the lab, put it on your computer at home (even if you don't have word...just don't try opening it) and then sending in everything together from there. If you need more help with this, IM a TA or go to someone's office hours. Amanda Bennett

When I download the jes.zip file I don't get a jes.exe file within the zipped files...am I doing something wrong - I have Word 2000. Thanks

I meant Windows 2000 for the previous posting...sorry

Did you download the course software from this site http://coweb.cc.gatech.edu/mediaComp-plan/94 ? Albert d'Heurle

In your eample 2 code are you sure you have the line file = pickAFile() ? Albert d'Heurle

When I attempt to open the extracted jes.zip file, it begins to open JES - but never finishes loading or starting up JES. Is there another way to retrieve my JES submission?

The answer to this question is posted elsewhere on this page, as well as in the announcements page. Kelly Lyons

do we need to put our names on the python and word document files and if we did will points be taken off?

no and no Amanda Bennett

When I spell check the word document, the word "writibility" is spelled wrong, but I don't think it's a word at all because there is not a correction for it in spell check. Should I leave it the way it is or seperate it into "write ability" ?

Lab 3

Is embedding flash objects going to count for or against my grade on this lab?

As long as you have all of the requirements and there is nothing offensive it should not count against you. If you're worried about it for any reason, I'd suggest you leave it out until after you recieve a grade and then feel free to add or subtract whatever you'd like. Kelly Lyons

My text editor saves things as .rtf and says I cannot save a text file as .html . What should I do?

Use a different text editor. Kelly Lyons

I have finished the entire lab and made my website a prism website, but how do I edit my webpage since I have already made it a prism website? There is one mistake I made, and I don't know how to change it on my prism website!

The easiest way would be to create a new file with the correct html in it and with the same filename (index.html I assume) and then reupload it. This should copy over the previous file and update your site. You could also edit the file directly. This would require connecting to and working from the acme computer. Kelly Lyons

If you have a copy of the .html file that you wrote in notepad on your computer, you can make the changes you want and then upload the updated version to acme.gatech.edu (the same you uploaded it the first time). If your .html file is not on your computer(you are using another computer), you can log into WinSCP and copy the index file onto your computer (the same way you copied the files from your computer to public folder). Make your changes and upload it again. A third way is to directly using WinSCP. Right click on your file in the public folder and hit edit. Make your changes and save. Hope that helps!

do the requirements need to be on the frontpage (home) or could they be on sequential pages with links on the first page?

They can be on linked pages so long as all of the requirements are linked from the main page. Kelly Lyons

ok, so to begin this lab, we just start typing HTML in some notepad/text edit, then upload it to prism website?

Pretty much :) Amanda Bennett

When exactly is the due date for this assignment? Is there somthing I've missed?

Check the syllabus. -Blake O'Hare

how can you make a jpeg the background of the webpage?

<body background="your_image.jpeg"> -Blake O'Hare

is it alright to use javascript for some of the extra stuff?

As long as you don't blind your TA with flashing popups or exploit Internet Explorer weaknesses. -Blake O'Hare

does the filename have to be index.html? because i have three files, the main one is my index file, which runs the other two. and the other two, one is a frame on the side of my site, and the other is the actual page. i can submit all three or i can submit the index file. what to do?

"Submit?"
When you upload your page, we will go to the following URL...
http://www.prism.gatech.edu/~gt[whatever your prism ID is]/
When we get there, we'll expect to see your page. That is all. However you want to rig it up is fine by us as long as we see it by going to that URL which requires the first page you see to be called index.html. -Blake O'Hare

My picture just shows up as the little red X box instead of the picture itself. And it won't appear even if I right click and choose "Show Picture." Any ideas of what I did wrong? I uploaded the file correctly as far as I can tell. Thanks.

Remember to use a relative URL and not an absolute URL. Also, make sure your capitalization is correct. -Blake O'Hare

Is writing in HTML like writing in JES where we have to indent and space correctly? Or is the only reason we indent and space to make it easier to read?

It's just to make it easy to read. You could do your entire web page on the same line and it would look the same in the browser. -Blake O'Hare

do my images have to be jpg or can they be .gif too?

As long as they display correctly, GIFs are fine. – Matt Britt

im trying to preview my html code and make sure it is doing what i want it to, so i have the text (i typed it in wordpad) in wordpad but when i went to do save as i could only save it as a text file or all files, i couldnt save it at html, so i tried notrpad and that didnt have html as a save as option either, how are we supposed to do this?

when you save it, go to all files. when you type in the name, type in name.html and that will save it as html :) Amanda Bennett

where should i put my align="center" for my picture?

<p align="center"><img src="whatever" /></p> -Blake O'Hare

i tried that and it didnt work, i put in this is what is centered blah bla blah and it worked perfectly, is that wrong?

is there anything special we should put in the title line?

do we have to put

...or can we just put

You know, if you use < instead of <, your HTML will actually be readable when you post it.

it's giving me an error when I try to make the public_html folder when you load up WinSCP for the first time...it says, "Can't create folder 'public_html.'" and when I click on More it says:
"Permission denied.
Error code: 3
Error message from server: Permission denied
Request code: 14"

It worked when I clicked on the left side and made a folder in My Documents, but it won't make one when I click on the right side. Any suggestions?

nevermind, I loaded the thing again and it worked. :)

I did everything that the instructions said to put my files on my prism account. When I go to my prism web address it says "index of files" instead of having the web page come up. What should I do about this?

Make sure you have a file in your list of files that is named index.html -Albert d'Heurle

I have a question about adding the picture to the page. Why is the preferred method to use pictures on our computer? How do other people see our picture if it's not on their computer? Does that make sense? Just a little confused over here...

Upload pictures from your computer to your personal webspace so that when people view your webpage, the pictures they see are FROM YOUR WEBPAGE as opposed to linking to images that are on some other website. -Blake O'Hare

I'm having problems with my picture too. What's the difference between relative and absolute URL's? I didn't see that in the tutorial or in the lecture slides. My line looks like this:

<img src="me at homecoming 05.jpg" />

That's the exact name of my picture and it's on my desktop...

Relative URL's are like the one you have shown above. Absolute URL's are things like http://www.prism.gatech.edu/~your gtg number/me at homecoming 05.jpg.
Is your webpage on your desktop too? When you upload your .html file, make sure you put that image in the same folder. -Blake O'Hare

when i went to my prism website it had this:
Index of /~gth872k
Parent Directory (this is a link)
index (this is a link)
rose.jpg (this is also a link)
why didn't my webpage show up? i have to click on the link "index" to get to my webpage, and the picture was not in my webpage. I have to click on the link "rose.jpg" to see my pic. how can i fix this?

Question 1: It needs to be named index.html or index.htm, not just index.
Question 2: there is something wrong with your HTML. You are probably using an <a> tag instead of an <img /> tag. -Blake O'Hare

how can i contact leslie, my ta? i emailed her yesterday to setup an appointment for individual help, but i still have no reply, and time is ticking away
is there a number i can call her?

Do keep in mind that yesterday was still Fall Break and TA's go out of town too. We're required to check our email every 24 hours while school is in session and only once during breaks, so you should be receiving a response soon. -Blake O'Hare

thanks, blake

Anytime. -Blake O'Hare

On our main page, does our picture have to be by ourself or can it be with other people?

Can you give me any direction as to how to use a Rollover image?

Also, I am having the same problem as the person above who gets
Index of /~gtg111a
Parent Directory (this is a link)
index (this is a link)
rose.jpg (this is also a link)

The name is index.html but I don't understand what you mean by the tag because I don't think I am using in the wrong place.

It does need to be index.html, but the text you pasted indicates that it's just called index without the .html. Rename the file and (assuming all permissions are set correctly) it will work fine. -Blake O'Hare

When I go to my webpage...www.prism.gatech.edu/~gtg111q, the first thing that comes up is "index of/~gtg111q". I just want to make sure that this is what is supposed to come up. Because in order to view my actual website you have to click on "website.html". On that note, is "website.html" supposed to be named something specific, or can it be an arbitrary name? thanks!!

index.html -Blake O'Hare

I did what you said above, saved with index.html, and I loaded my stuff to prism just like it said, but when I go to my site it says.....

The requested URL /~gtg818x/ was not found on this server.

What does this mean? Have I gove wrong at a certain place that gives you this message?
When I view my site it looks fine but it just isn't on the web yet.

How can I hyperlink my main index.html file to another html file? I tried using the relative html(the file name), but when I try to go to it in internet explorer, it just says the page is not found. I can open each page sepeartely, buy I can't hyperlink one page to another. What am I doing wrong?

As I copy my files into public_html, I can see "Index of /~gth391a" and the files on my prism webpage. Once I click on my gt number, and go to hte webpage, it tells me that "you are not authorized to view this page or something". What is going on??

The permissions need to set correctly. This information is located Here -Albert d'Heurle

My webpage works perfectly, excpet when I go to www.prism.gatech.edu/~gtg391g it brings up an index of all my jpgs and htmls...how do i get rid of this and just have my webpage come up?

Make sure your main html file is named index.html -Albert d'Heurle

Also, after I click on my gt number and click properties - I am unable to click "ok" with the octal # 0751( its not highlighted) - I am kind of stuck here.

I am having trouble downloading the winSCP to my computer... whenever i click on it, it states that there is no specified application to open it with and i have no idea which one to choose!!! please help so i can make my prism account... thanks

How can I change the color of my hyperlinks? Is is done the same way as changing fonts?

Not all of my pictures show up when I go to my website but when I click on them in the folder on the acme site they all show up of there. They are in jpg format but I do not know only a couple are showing up?

Sometimes things are case sensitive. like .jpg is not the same as .JPG. Let me know if that helps. -Albert d'Heurle

i have completed my web page and I tried uploading it to my prism account. When i click on the webpage to make sure it works the homepage's pictures do not show up, however I have four pages and the fourth page has a back to home page button, when you click on that button it takes me to my homepage and the pictures are now there. what do i need to do for the pictures to show up the first time

Can a scan of my buzzcard count as a picture? I don't have any pictures of myself

Sure but I would hestitate to put my ID card on a website. -Albert d'Heurle

Is a clickable image link a hyperlinked image or something else?

you are correct -Albert d'Heurle

I have finshed my page and i uploaded it to the account. On my homepage I have sentence you click on to take you to the next page. It works when I just open index.html however when i go to www.prism.gatech.edu/~gth803s it takes me to the homepage but i cant click on the link

Did you make sure you uploaded the html file for the other page? -Albert d'Heurle

How can I change the color of my hyperlink?

You can use the following tags where link is the color of links that have not been clicked, vlink is the color of links that have been clicked and alink is the color of the link as it is being clicked. Hope this helps -Albert d'Heurle

I uploaded all the html files for the other pages however it still doesnt work

Did you make sure that they are in the same directory as ypour index.html file? When you created your webpage where all of the html files in the same folder? Make sure you set you the links correctly in your main index.html file. Spelling counts. Also your premissions might not be set correctly -Albert d'Heurle

Albert, thank you for the case sensitive advice on the pictures! That helped out tons!

Glad to help -Albert d'Heurle

How do we get the main html file to be named index.html??

When you are using winSCP you should be albe to right click on the file and click on rename. Another way would be to save the file as index.html. -Albert d'Heurle

is a group picture okay?

Sure -Albert d'Heurle

What tag do I use for the link? I tried and but neither worked, and I don't know where to go from there.

Sorry, I forgot to link the html part. I just had the explanation before. Try this:

<body bgcolor="#FFFFFF" vlink="#FF0000" alink="#00FF00" link="#0000FF">

-Albert d'Heurle

ummmm above was "I tried link="..." and link color="..." but..."

Can I use a photoshop image(with .psd) as a picture, or will it not work in html?

I do not think a .psd will work. I would open up photoshop and save the picture as a jpeg. -Albert d'Heurle

Do we need to include a DocType tag at the beginning of our HTML Code and if so, where do we find one to use?

Yes, include a DOC type. You can use this one

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

-Albert d'Heurle

How can i add a border to my table?

After you start your table add the line

 <Table border ="1">

where the number is the size of the border. -Albert d'Heurle

I keep trying to use a JPEG image named blue012 as my background. When I put in bgcolor="blue012.jpg", I get a solid red background. I tried to use blue012.JPG and got the same thing. What am I doing wrong?

Do use a background image you have to use the tag

 <body background="image.jpg">

. The .jpg should work fine but be aware that the endings can be case sensitive -Albert d'Heurle

how can you modify the text between the heading tabs? Do you put font tabs inside the header tabs?

Yes. Or if you're modifying the text inside the heading so much, you could just leave off the <h#> tag and just use <font. -Blake O'Hare

how do you make a picture a hyperlink?

Instead of having text after the a href tag you will use the tag to insert an image. So

<a href="page.html"><img src="turtle.jpg"></a>

. -Albert d'Heurle

when i uploaded my index.html to prism and went to view the webpage, my jpeg i have for the background didn't show up. i tried re-uploading that file and it still won't work. ideas?

Did you make sure you uploaded the picture you used for the background? -Albert d'Heurle

Can we do our picture change when the mouse goes over it on the secondary page for extra credit or should I move this extra credit part to the main "index.html" page. I put it on the secondary page to preserve my html tags for that portion of extra credit.

I think that will be fine -Albert d'Heurle

1) Does the Dogtag go on the top of our index.html file?
2) Does it go on additional pages that are created by us or only on the index.html?

Im not quiet sure what you mean by dogtag. But if you meant doctype then yes it should go on the top of the index.html file and every other html file you creat. -Albert d'Heurle

Is there a way for me to scale my background image so that I don't get a lot of small background squares but just one big square that takes covers the entire background? Even my bigger background images don't fill up the entire background.

You could use JES to make the picture bigger :) or you could use another program to edit the picture and make it bigger. -Albert d'Heurle

i have created my webpage and all of my pictures are uploaded correctly. however, everytime i go to post my page it keeps telling me that i dont have permission to view the site. can you possibly tell me what could be the problem? i have done it like 20 times.

You need to set the permissions for the folder, files, and your ~gtg#### folder. -Blake O'Hare

i don't understand how to make a picture clickable. do i use this code:

how can i make a click on a picture, direct the viewer to a different webpage?

Those are the right tags, but you have a few space and slash typos. If you want to go to a different webpage, please remember to include the http:// -Blake O'Hare

I keep trying to download winSCP and after it connects to host it says that I need a session login password. What the heck is going on? How do I get into the program?

That's your prism ID and password. Please read the WinSCP tutorial. -Blake O'Hare

how can i create more than one page? I want to do the extra credit part, but i have no idea how i can get more than one page.

Well you have to creat a new page with a different name say newpage.html. Then in your index.html you would add the link

<a href="newpage.html"> New Page</a>

. Hope that helps -Albert d'Heurle

so we just upload this html file and pictures to the prism thing and we don't upload anything to webwork correct?

Yes. Make sure you can load the page from your prism account. -Albert d'Heurle

I use Mozilla Firefox as my browser, and everything looks great on it and the way I want it to. But when I pull it up on Internet Explorer, everything that's supposed to be center isn't. Why is this?

Internet Explorer is evil in its purest form! Hope this helps you with your centering problem.

In all seriousness, IE makes some weird guesses about alignment especially when it comes to tables. You can get around this by specifying that you want certain text to be left-aligned. Usually this involves adding an align="left" attribute to the tag containing the text that you don't want to be centered. -Blake O'Hare

my jpeg file for the background was loaded, but it won't show up.

?

Please rephrase this. -Blake O'Hare

Yeah I know, I hate Internet Explorer. But what I meant was, when I pull up my webpage in IE, the things that are supposed to be centered aren't. So all everything is aligned left when it's supposed to be aligned center.

^That was my question. Nevermind, I figured it out. IE was being picky about where the tags went, so I fixed it.

Oops, I read that too fast. Even though you figured it out, if anyone else is having the same problem, just take what I said above and replace "left" with "center" to fix it. -Blake O'Hare

Ok, i can pull the page up in firefox but not internet explorer, how do i fix this?

If your page renders in one browser but not in another, this is usually a good indication that something really funky is going on with your tag placement. Double check your main tags such as <head> and <body> and make sure they're being used the correct way. Also check to make sure all your tags are closed and all attribute values have both an opening AND closing quotation mark. This is kind of odd, because it's usually the other way around since IE is more forgiving about that kind of thing than FireFox. Or I might be misunderstanding what you mean by "pull the page up". -Blake O'Hare

if we use a tag to set the background and text color (such as:
<body text="#9999FF" bgcolor="white"> )
do we also need to use a beginning body tag beforehand?

There is only one body tag. Ever. -Blake O'Hare

what i've typed between my head tags is showing up on my page. It's not included within the body tags....is there a way I can fix this?

nevermind on the head tag stuff... i forgot to use the title tag

i have a jpeg for my background, and it works fine on my computer. when i uploaded everything and viewed my prism site, the background image would not show up. ideas?

Your webpage on your computer is not case sensitive about filenames. On prism, it is. Usually when this happens it's because you used .jpg instead of .JPG or vice versa. -Blake O'Hare

Can we still get the additional 5 points if everything other than our Javascript is HTML Formatting standards-compliant?

Javascript isn't HTML. So yes. -Blake O'Hare

I used a .gif file on my site and it keeps appearign with these borders around it. How can I get rid of the borders?

<img src="whatever.gif" style="border: 0px" /> if memory serves correctly. -Blake O'Hare

rollover images are complicated to do, i researched them and the codes are quite confusing. this is what i found:

can u explain this code?

If it works, it works. Personally, I'm not sure I can entirely explain the code you posted. However, I can say there is a MUCH shorter way to do this. Keep Googlin'. -Blake O'Hare

okk, my code that i found did not display, how can i show my code, without it being processed

Use < in place of <
The gray box on each page's edit page has a list of these codes. -Blake O'Hare

this webpage has great rollover images, but the code is hard to understand

can u explain?

See my above statement. -Blake O'Hare

I'm getting this error when trying to mount

General failure (server should provide error description).
Error code: 4
Error message from server: Failure
Request code: 14

Any suggestions?

You should be able to use WinSCP without going through this. -Blake O'Hare

To the people with the rollover question...I'm not a TA, but you can use the codes "onmouseout" and "onmouseover".

It looks kinda like this:

I put it in my code and it works fine.

My rollover pictures work fine in IE, but when I tried them in firefox, one of the pictures doesn't show up. You can only see the second picture. Also, I noticed a color change issue between the two browsers. My links look a lot different in firefox than IE, but changing the colors doesn't help much. One color looks good in one browser but makes text unreadable in another. What can I do?

Specify the colors rather then let it use defaults. Use the color attribute in the font tag or the link, alink, vlink attributes in the body tag to specify color. -Blake O'Hare

My picture literally disappears when you rollover it. When the page loads, it appears and the rollover works the first time, but once you move the mouse away, the picture disappears. What going on here?

There is something wrong with your onmouseout code. Perhaps an invalid filename? -Blake O'Hare

I downloaded my page and all accecories to prism and it came up with them all indexed. How am I supposed to indicate which one is my main page?

Rename the main page index.html -Albert d'Heurle

Lab 4

do we need to include a bibliography from our research in the slide show or is the purpose solely to get us familiar with powerpoint?

No you do not need a bibliography. The goal of the assignment is mainly to learn powerpoint. 85% of your grade is determined by your powerpoint skills and 15% on your topic. Kelly Lyons

whats a slide transition?? it doesnt say anything about those in the lab overview...

nevermind that question... im a little blind

A slide incorporating a picture, graph, chart, etc. from a source besides PowerPoint (ex. Internet, Excel, Photoshop, Digital Camera, Scanner) [15 points]
Does your slide show have to include all of these or just one of these? And I don't see the extra credit for this lab, but one of the TA's told me there was, where is it?

There needs to be at least one of those listed (picture,graph,chart, etc). You do not have to have one of each. There is no extra credit for this assignment. Your TA was mistaken. Kelly Lyons

What should we name the file? I can't seem to find the correct filename on the website...

hmm nevermind....im a little blind as well :o)

Is clip-art from powerpoint considered a visual created with the drawing toolbar?

I do not think that will work -Albert d'Heurle

when is the lab due?

Monday, November 14 -Albert d'Heurle

Is word=art considered a visual created with the drawing toolbar?

And what about auto shapes?

If you use something on the drawing toolbar to make a slide, you should get credit.poof #10

I was wondering if video game playing doctors count under the computer theme of the powerpoint......I think its an intersting topic.

If you can provide a valid link to computers, it would count. Kelly Lyons

Lab 5

what i've typed between my head tags is showing up on my page. It's not included within the body tags....is there a way I can fix this?

My, my, you're jumping ahead. -Blake O'Hare

That posting today is freakin hilarious. Kudos.

Should we get the absolute value the Percentage Change column (column I)? Or should there be postive and negative percents?

The percent change can be negative Kelly Lyons

im confused about the way we right the code to find the motion below, i dont understand what that means and what you are looking for. Also when i was working with the error margin for the trendline it gave me this message that said "The maximum number of data points you can use in a data series for a 2D chart is 32000 if you want to use more than 32000 data points you must create two or more series" im confused what's going on, i thought i restriced the number of points when i set it up.

The motion below is calculated the same way as the motion above, only you will use the low column instead of the high column to get it. Kelly Lyons

There is no option to submit Lab 5 in WebWork...only HW6 is available. Please check this and make Lab5 available to turn in.

So....Lab 5: Excel....I'm having a problem making the error lines in the graph. I have a mac and the option to choose a column beside the + box and the - box is not available. Please Help!

Im having problems with the error lines showing up also but i dont have a mac, the boxes are available but it doesnt give you options of what to choose. Im also havin propblems with the bold and the bold red showing up, I have it as conditional formatting but, its still not showing up.

The submission for Lab 5 becomes available tomorrow when the assignment officially comes out on the syllabus Kelly Lyons

After I do the error bars it gives me this message: "The maximum number of data points you can use in a data series for a 2D chart is 32000 if you want to use more than 32000 data points you must create two or more series"
What does this mean? Does it affect the data at all?

As long as the error bars are there, you can ignore the message. It's usually just a warning. If the error bars aren't showing up, you should go see a TA. There might be something else weird going on. Kelly Lyons

For column I, the positive percentages should be bold black and the negatives bold red, right? So when it says, "On your own, go back and add a second condition to the I column of cells..." does that mean we need to add something else, or is it just the bold red/black?

Just the bold red and bold black. I believe the instructions tell you explicitly how to do one of them. So the on your own part is referring to the other one. Kelly Lyons

with the percent change how do you find the precent change for column I2 because there is no number before E2. should you leave that box blank?

You can do that, or you can put the formula in and it will just have an error. Kelly Lyons

do we have to do anything with the absolute formulae?

No. It was just there to tell you it exists. Kelly Lyons

im trying to do the error bars, but i dont have an option of what column to choose, what do i need to do?

I just lost everything I did because it didn't let me save it in the format we're supposed to. It didn't want to let me save more than one sheet, so can I put my chart on the same page as the data?

Never mind that last post about saving it, I figured it out.

My graph for the scatter chart keeps coming up in a straight line- is that how it is supposed to look? If not, what am I doing wrong- I followed the directions completely through... Please help

basically- what should my x coordinates be? because right now in my graph all the x coordinates are 1...

The x coordinates should be the date. Kelly Lyons

So the graph looks a little finny....all the points are in the same area(around 25). So is this okay or do I need to fix the graph?

If the points are all around the same area, then it means that the stocks never rose or fell. Go back to your data and look and see the stock values. If they don't ever change much, then you're ok. If they do change then you've made a mistake somewhere. Kelly Lyons

When I add error bars to the graph, it completely changes my graph to where it has a very small range. Aren't the error bars just supposed to be additions to the graph?

It shouldn't completely change the graph. You probably did something wrong somewhere. Kelly Lyons

I am trying to add the error bars, but there isn't an option for me to choose a column - A blank window pops up when I click the button - but thats it???

I'm having the same problem!

It's difficult to fix this problem without seeing what is happening. You are probably using a different version of Excel than the lab was written in. Try going to a computer lab on campus or seeing a TA in office hours. Kelly Lyons

Exactly when is this due? The lab page said Monday, the course outline said Wednesday....so, which is it?

It's due on Wed. The lab page says Wed. Kelly Lyons

For the last part with column I, do you want the whole column to be red and black bold or do you want only from 12 down to be? Im confused

The whole column should be red/black. The first column however may not be depending on how you did it because there's no previous day to compare with. Kelly Lyons

when you go to add the error bars, once you hit the button to select column G, you need to go back to the disney prices sheet and select it. it fills it in then.

do we actually have to alter anything in the Excel.py to have the updated stocks? because the values I have are identical to those given in the .txt file. where should I change the code to have updates?

You need to change the output location so that it is saved to a place on your computer. The values should not be identical to the .txt file. They dates should be more recent up to the present time. Kelly Lyons

how should i input the $ before each character without going through each cell and changing it?

If you do it in one and then copy and paste, it should save the $ Kelly Lyons

After we sort the data from earliest time to most recent time, the instructions in the lab do not tell us to change the graph? Is the graph automatically changed when we change the chart? If not, should we make a new graph to reflect the newly sorted data? Also, I am experiencing the same issue as someone above when we add in the error bars the scatter plot/line graph changes to look like it has a small range. The y axis range is 1.00 - 35.00 so the graph stay around +/- 25. The data is accurate but it was not what it looked like before. Is 1.00 - 35.00 the correct range for y axis?

I am the person who was having problems with the error bars - I wasnt able to select a column - I just tried doing the assignment on a computer in the library, and the same blank window popped up? Any suggestions?

WebWork keeps saying database error. Wont let me retrieve my assignment. Is anyone else having this problem? (Tuesday 4:50 PM)

Yep - I'm getting the database error too -

Webwork is having issues. GIve it a day. Kelly Lyons

The graph should automatically change when you change the data by sorting it. Blair MacIntyre

For selecting the column in the Error Bar dialog box, I did a little Google searching, and found an example that caused me to do something like this for the +:
=DisneyPrices.txt!$G$1:$G$66
with the corresponding thing for -. Blair MacIntyre

How do I save it? It asks if i want to save only the active sheet or if I want to save all of them (and to save all of them, it says i have to save them individually with different file names or choose a file type that supports multiple sheets). What do i do?

When you are saving your Excel file, make sure you save it as the directed file name and then select "Microsoft Office Excel Workbook" from the pull down menu "Save as type:" If you select save entire workbook then it will save your multiple sheets. Swati Vishnubhakat

I have several cells using the Excel.py that are filled with "######". Is this something that I need to worry about?

I just wanted to make sure that the I2 column should be blank, since we wouldn't know the percent change from the previous day without looking up the information.

Are we actually using the "$L$2" technique anywhere?

I cannot put error lines in because it says there is an "error in my formula", but I have no idea what it might be... I entered what the directions said!

how do are you suppose to know that we did the extra credit, i dont know exactly how to turn everything in (Lab 5)

The #### should appear in some of the data from the txt file. This is ok. If you are getting that in the cells that you are altering, this is not ok. The I2 column can be blank. That is ok. I can't tell if your formula is wrong if I don't know what you wrote. If you did the extra credit, your data will be more recent and the TA will notice the difference in dates. The file on the website is from a few months ago and so the dates are from a different time than if you do the extra credit and get the newer information. To turn it in, all you need to do is submit your .xls file which should contain the data sheet and the graph on a separate sheet. Kelly Lyons

Webwork won't let me retrieve my file that I submitted a few days ago. Is it working correctly yet? Or should I attempt to resubmit my file?

You should email your submission to your TA in addition to attempting to resubmit it. Webwork was having issues a few days ago. It should be fixed by now. But just to be safe, I'd email your submission to your TA. Kelly Lyons
