You have just entered room "cil102sidbury."
drjamessidbury: Good afternoon. Do either of you have a question before class begins in a short while?
BB uu GG 22 44: not at this time no
rtzjm8 has entered the room.
PaulinaM2012: not at this time either
marix3anne has entered the room.
drjamessidbury: so I'm assuming that this means that you are all squared away with lab stuff
borysboy has entered the room.
PaulinaM2012: yes, and i hope the pretest doesn't count as a grade, because i did horribly on it :-(
drjamessidbury: the pretest is part of the assessment of this course and familiarization with the system
rtzjm8: The code that you emailed to us is for after we enter the access code, correct?
drjamessidbury: That is you will take the pretest again at the end of the semester and my department will analyze the difference in scores between the pretest and post test of everyone to see how much you are learning.
drjamessidbury: so if you screw up the pretest then that will make me look like a good teacher
marix3anne: what is this pretest?
drjamessidbury: as long as you don't screw up the post test
marix3anne: which lab is the pretest, i mean
PaulinaM2012: i'll keep that in mind :-)
drjamessidbury: but neither one counts anything on your grade unless you just blow it off
drjamessidbury: the pretest is located in the myITLab site
marix3anne: oh okay
rtzjm8: The code that you emailed to us is for after we enter the access code, correct?
drjamessidbury: ???
drjamessidbury: oh, yes
rtzjm8: OK, thanks!
rtzjm8: I had a quick question about the website
drjamessidbury: the access code is what you buy from pearson ed that gets you on the system
drjamessidbury: the code i sent you is for this particular class to allow you to enroll in it.
drjamessidbury: BTW I mailed your CD today so you should have it by Wednesday I hope
drjamessidbury: which web site
drjamessidbury: mine
drjamessidbury: cil102
drjamessidbury: myITLab
rtzjm8: I am still having trouble publishing it. I was able to transfer the files to the server using fetch cil102
drjamessidbury: you can't publish
borysboy: I couldn't publish either
drjamessidbury: we "fixed" the web site so that you can't use regular ftp on it
rtzjm8: but when I typed in the IP address that I had created, I got a 403 message
borysboy: I tried that SFTP and it still wouldn't let me publish
rtzjm8: I was able to connect using SFTP.
rtzjm8: I'm not sure if I published or not. I transfered the files to the server, or so Fetch said
drjamessidbury: I sent everyone an e-mail which basically said that the only to put stuff on the web site is to use an encrypted transmission and neither NVU nor KompoZer can do that so you will have to use Core FTP or FileZilla or Fetch
drjamessidbury: but SFTP works fine
marix3anne: where does this leave those of us who used nvu to make the website but still have to make changes and upload things?
drjamessidbury: the main difference is that you have to use port 22 or check the SFTP or SSL box to enable encryption on the FTP software.
marix3anne: so nvu still works?
drjamessidbury: you can see if it worked by trying to look at your web site
rtzjm8: I tried that I got a 403 message
drjamessidbury: nvu still works to make a web page but you can't put it on the internet with nvu
marix3anne: okay so do i have to do everything over again?
drjamessidbury: this change makes putting stuff on your Web site safer
drjamessidbury: no if stuff is there then it's there
marix3anne: what about uploading homework?
borysboy: When I go to my web page it says I don't have permission to access it
rtzjm8: I get the same message.
marix3anne: me too
drjamessidbury: and maybe you have a copy of NVU with SFTP available but my copy doesn;t have this
marix3anne: i am not familiar with SFTP but im sure if yours doesnt then mine doesnt
drjamessidbury: if it says that you don't have permission that means that there's nothing there to access so the stuff that you tried to copy didn't get ther
drjamessidbury: SFTP stands for Secure FTP which encrypts the page to send it
marix3anne: but i used to be able to see my website, so i know it was at one time there
rtzjm8: Do you have any suggestions?
marix3anne: actually the message that i get is that the url is not found on the server
drjamessidbury: who are you?
rtzjm8: Molly Hritzo
drjamessidbury: the problem with your site molly is that you put all your files in your account and you were supposed to click on the public_html folder in your account before copying stuff into it
drjamessidbury: it's there but just in the wrong place
rtzjm8: Oh, ok, i'll try it now. Thanks~!
drjamessidbury: ROLL CALL
borysboy: Jesse Borys
rtzjm8: Molly Hritzo
PaulinaM2012: Paulina maida
marix3anne: marianne patterson
BB uu GG 22 44: Donald Belcher
rtzjm8: Yeah! It worked! Thanks for the guidance
drjamessidbury: Any questions about lab?
drjamessidbury: Are any of you other than Molly mac people?
marix3anne: yes
marix3anne: how should i upload homework to the website?
drjamessidbury: there is a set of instructions on the notes page
drjamessidbury: but basically you will do two things
drjamessidbury: change whichever homework page you are using to put a link on the page
drjamessidbury: so for example if you're doing the security lab then you would write a paper called security.doc or security.docx.
marix3anne: ok
drjamessidbury: then use coreftp or filezilla or Fetch to copy that file to your Web site
marix3anne: is this a problem if i have already used nvu?
drjamessidbury: then put a link on you Lab homework page that points to the paper
drjamessidbury: no
drjamessidbury: since you've used nvu
drjamessidbury: you should have a copy of your homework page on your web site AND ON YOUR COMPUTER as a backup copy
marix3anne: ok...
drjamessidbury: just load the backup copy into NVU and make the changes, then save it to yuor computer
drjamessidbury: then use whateverFTP to copy it back up to your Web site overwriting the old version
marix3anne: when i saved it, it saved as a firefox document, so i cant make changes to it
drjamessidbury: ???
drjamessidbury: what is a firefox document?
marix3anne: like i saved it to a flash drive and it comes up as html, i guess
drjamessidbury: ok well then when you open your flash drive point to the file and RIGHT click and one of the options should be Open with
drjamessidbury: choose that and one of the options should be NVU
marix3anne: okay
marix3anne: thanks
drjamessidbury: if nvu is not an option then there should be an option to choose the program to use and you can get to nvu with that
drjamessidbury: anything else from anyone?
rtzjm8 has left the room.
BB uu GG 22 44: How Do you add a new link on your website To direct you to a different page?
drjamessidbury: the way you did it when you made the page
drjamessidbury: that is
drjamessidbury: open the page in nvu or kompozer or whatever
BB uu GG 22 44: oh okay
drjamessidbury: then move the cursor to an appropriate place and click on the link icon and fill in the window with the corerct info
BB uu GG 22 44: rights okay thanks
drjamessidbury: are we ready to finish data?
marix3anne: yes
borysboy: yep
PaulinaM2012: yes
rtzjm8 has entered the room.
drjamessidbury: the following topics are review: binary and hex numbers and bits, bytes and words
drjamessidbury: are there any questions from those sections?
marix3anne: nope
BB uu GG 22 44: no
rtzjm8: Nope
drjamessidbury: the new material will be on: storage of numbers, words, images, sounds, compression, and animation and video
drjamessidbury: so lets start with numbers
drjamessidbury: numbers are ...
drjamessidbury: numbers
PaulinaM2012: thats deep
drjamessidbury: numerals are the way we represent numbers when we write them down
drjamessidbury: so the number 12 represents a certain concept
drjamessidbury: in ancient historical times the number system was
drjamessidbury: one
drjamessidbury: two
drjamessidbury: many
drjamessidbury: but that didn't work out too well
rtzjm8: especially when you have herds. Haha
drjamessidbury: for one thing when there was a war with another tribe and the scout came back with a report that the other tribe had many fighters and told it to his 4 fighters then it was an even fight
drjamessidbury: until it turned out that the other tribe had 46 fighters
drjamessidbury: yes and as you suggest it's not good for agriculture either
drjamessidbury: people could steal your cattle and you wouldn't know it
drjamessidbury: anyhow since computers use the binary number system all numbers are represented in binary
drjamessidbury: mathematically numbers fall into two classes: intergers and real numbers are the names that mathematicians give these two classes
drjamessidbury: intergers are just whole numbers
drjamessidbury: real numbers are numbers with decimal points in them
drjamessidbury: so on a computer the number 7 is not the same as the number 7.0
rtzjm8: because the decimal and zero use more bits
drjamessidbury: intergers are often called fixed point numbers to emphasize the fact that the decimal point is always located in the same place and therefore we can just leave it out to save space
drjamessidbury: fixed point numbers are exact
drjamessidbury: there is NO error in representing them
drjamessidbury: usually
drjamessidbury: wait
drjamessidbury: for
drjamessidbury: it
drjamessidbury: the problem is that there is a size limit
drjamessidbury: all fixed point numbers are stored using the same amount of space
drjamessidbury: normally
rtzjm8: 32 bits
drjamessidbury: so the number 12 uses exactly the same amount of space as the number 2342098
drjamessidbury: in your computer (and mine) it's 32 bits
rtzjm8: great use of space!
drjamessidbury: the first one for the sign 0 = +
drjamessidbury: 1= -
drjamessidbury: why not the other way around?
drjamessidbury: because
drjamessidbury: that's the way they were originally designed
drjamessidbury: the other 31 bits are used to store the number
rtzjm8: but that limits the numbers
drjamessidbury: and although the space usage is not efficient that is more than made up by the fact that this technique allows computers to perform arithmetic very quickly
drjamessidbury: the numbers are limited to approximately plus or minus 2.15 billion
rtzjm8: well the multi-billionaires are out of luck doing finances
drjamessidbury: if you want fixed point numbers outside of that range you either need to approximate them with decimal numbers or find another way of representing them
drjamessidbury: the rich people can represent their money using decimal points so 50 billion dollars is 50000000000.0
drjamessidbury: or 5 x 10 (to the power of 10) assuming that I counted correctly
drjamessidbury: negative numbers are represented differently than positive numbers.
drjamessidbury: for example the binary representation of the number 5 is 101
drjamessidbury: so on a computer it would be represented as 00000000000000000000000000000101
drjamessidbury: but -5 would be represented as 11111111111111111111111111111011
rtzjm8: the 1s being the negative?
PaulinaM2012 has left the room.
drjamessidbury: the method is called twos-complement and you can google it if you're curious
drjamessidbury: decimal numbers are referred to as floating point numbers to indicate that the decimal point can be anywhere
drjamessidbury: Are you familiar with the fact that 234.1131 = 0.2341131 x 10 to the 3?
rtzjm8: yeah, scientific notation
marix3anne: yes
drjamessidbury: actually it's called exponent notation. In scientific notation the digit to the left of the point is never a zero (unless the number is zero)
drjamessidbury: while in computing the number to the left of the point is always a zero
drjamessidbury: but the idea is the same so if you think "scientific notation" then you'll be OK
rtzjm8: sounds good
drjamessidbury: exponent notation is actually done in binary so the number 12.75 is actually 12 + 3/4 and the 12 is 1100 and the 3/4 is .11
drjamessidbury: Who sees that?
drjamessidbury: and who doesn't?
drjamessidbury: in binary 12 is 8 + 4 so 8 is 1000 and 4 is 100 so add them together and you get 1100
marix3anne: can you explain that?
borysboy: /what do you mean 3/4 is .11?
rtzjm8: oh, I get it
drjamessidbury: the 3/4 is 1/2 + 1/4
marix3anne: oh, okay
BB uu GG 22 44: i see it yes
drjamessidbury: now in binary as you move to the left the POSITION value increases by a factor of 2
PaulinaM2012 has entered the room.
drjamessidbury: in decimal 21 the 2 is 2 tens and the 1 is 1 one
PaulinaM2012: sorry about that, i lost my connection for awhile
drjamessidbury: so 21.45 is 2 tens plus 1 one plus 4 1/10's plus 5 1/100's
drjamessidbury: in Binary the moving factor is 2 instead of 10 so as you move to the left the position multiplies by 2 and as you move to the right the postion is divided by 2
borysboy: what would the whole number look like in binary? how does the computer know where the decimal point goes?
drjamessidbury: 1101 has the left most 1 worth eight and the next 1 worth four and the 0 worth 2 and the last 1 worth one
drjamessidbury: so as you move right the value gets halved each time
rtzjm8: that makes sense and it makes it easier too
drjamessidbury: so 1100.11 has the first digit after the binary point (!) worth 1/2 and the second position worth half of that or 1/4
drjamessidbury: the computer knows where the decimal point goes because when you type in the number you put it in
borysboy: oh ok so decimal points are in binary code
drjamessidbury: if the number is already in the computer then it's already been converted
drjamessidbury: the point is not coded
borysboy: ok I thought it had to be coded like +/- does
drjamessidbury: when you write a number with a decimal point the computer knows that it should be represented as a floating point number
drjamessidbury: BUT THERE'S A GOTCHA
drjamessidbury: When you type a number in a word document it's not treated as a number but rather as a bunch of keys that's been pressed
drjamessidbury: because in certain contexts numbers are not treated as numbers but just as symbols
rtzjm8: so it registers the characters, not the numbers.
rtzjm8: how about powerpoint?
drjamessidbury: you don't do arithmetic on your phone number and your po box number because they don't really represent numbers they represent "addresses'
drjamessidbury: (unless you're computing what you hope will be the winning powerball number :-)
drjamessidbury: Powerpoint does it the same way.
drjamessidbury: Excel treats it differently
drjamessidbury: because Excel is used to do arithmetic
drjamessidbury: so when we refer to numbers in computers we are essentially referring to things that we do computations with
drjamessidbury: and in general floating point numbers have a much wider range of values BUT they usually are only approximations and are not exact.
drjamessidbury: For example you can't write the number 1/3 as a decimal number exactly
drjamessidbury: you would write .3333333 and stop after a while
drjamessidbury: which is not exactly 1/3
drjamessidbury: you can represent 1/2 exactly but not 1/3
drjamessidbury: since coputers use binary the rules are different in determining what can be represented exactly and what can only be represented approximately
drjamessidbury: There are two methods of representing floating point numbers
drjamessidbury: Programming languages like C or Java would call these two methods FLOAT and DOUBLE (not capitalized usually) but that make it clearer when I type
drjamessidbury: FLOAT uses 32 bits to store the number while DOUBLE uses 64
rtzjm8: why would you use 64?
drjamessidbury: with 32 the first bit is for the sign
drjamessidbury: the next several bits (7 of them) are for the exponent and the rest for the "fractional" part.
drjamessidbury: so + .231234 x 10 ^19 would put the + in the first position, the 19 in the next few positions and the .23 whatever it was in the last positions
drjamessidbury: the more spaces are reserved for the exponent the bigger the exponent can be and therefore the bigger the number can be
rtzjm8: oh, ok!
drjamessidbury: the more positions available for the fractional part the more accurate the number can be
borysboy has left the room.
drjamessidbury: as a rule of thumb (I wonder where that phrase came from) with 32 bit numbers
borysboy has entered the room.
drjamessidbury: the exponent can go from about -36 to about + 36 and the precision is about 7 significant digits
drjamessidbury: BUT if you use 64 bits then you have more space for the exponent and more space for the fractional part so the exponent can go between about plus and minus 300 and the accuracy will be in the range of 15 or 16 significant digits
drjamessidbury: when computers perform computations with approximate numbers the more computations that are performed the less accurate the answer becomes. So for example is you perform a thousand or more computations in some engineering formula and all the numbers are accurate to 7 places by the time you've finished the calculations the answer may only be accurate to about 3 or 4 places.
drjamessidbury: this kind of error is called truncation error and is an important consideration for scientific and engineering calculations
drjamessidbury: oops
drjamessidbury: it's called roundoff error
BB uu GG 22 44: Just curious does your hand get tired from typing all this LOL
rtzjm8: is that why in excel you have to specify the number of decimal points you want?
drjamessidbury: truncation error is the error that you get by cutting short a process to fewer steps than it shoud have
drjamessidbury: no, I have a lot of practice plus I have a good keyboard
drjamessidbury: plus I take a break occasionally
drjamessidbury: but now that you mention it....
BB uu GG 22 44: oh good okay lol
drjamessidbury: excel is more complicated than that
drjamessidbury: when you specify the number of decimal points you want in excel all you're doing is specifying the number of places that are shown on the sheet. The actual computations are independent of that.
drjamessidbury: so for scientific computations double precision should probably be used.
drjamessidbury: for most people (who aren't scientists and engineers) that's not a problem that comes up.
rtzjm8: oh so one should use all of the decimal points
drjamessidbury: even for people in accounting.
drjamessidbury: with finance it can make a difference because some of the computations that they make are complex
drjamessidbury: Basically you don't have a choice.
drjamessidbury: with word and powerpoint they are just symbols being typed so they aren't really numbers
drjamessidbury: for excel all you can specify is how many digits are actually printed on the screen or the paper
rtzjm8: not how many are processed
rtzjm8: or computed
drjamessidbury: So for example, I specify that the sheet SHOW only one decimal place in my grade sheet
drjamessidbury: the computation is actually done to 16 places but I don't need to know that your average at midterm is 81.121980123798729384792387492
drjamessidbury: 81.1 is good enough
rtzjm8: right, and for chem lab, I specify 3, but the computer still computes the other places
drjamessidbury: yes
drjamessidbury: but in chem lab the data that you're using may very well be something that you're reading so it may not be more accurate than 3 places
drjamessidbury: anything else before we go to words?
drjamessidbury: hearing nothing I'll go on.
marix3anne: ok
drjamessidbury: with words each character that you type on the keyboard is stored internally as a code.
drjamessidbury: now since you are seeing what I'm typing then your computer has to use the same codes as mine
drjamessidbury: there are basically 3 standard codes taht are used for storing keystrokes.
drjamessidbury: the first is ASCII (pronounced ass-key)
drjamessidbury: american
drjamessidbury: standard
drjamessidbury: code
drjamessidbury: for
drjamessidbury: information
drjamessidbury: interchange
drjamessidbury: it's the standard code that almost everything is stored in on the internet for now
drjamessidbury: at least here
drjamessidbury: so google and yahoo and the U and you and I have computers that use ascii
drjamessidbury: you can look up the codes online but basically they are arranged logically
drjamessidbury: so the code for B is one higher than the code for A
drjamessidbury: and the code for A is different from the code for a since A is not a
drjamessidbury: one is capital and one is lowercase
rtzjm8: how does the computer delineate in ASCII
drjamessidbury: a second code is EBCDIC (ib suh dik
drjamessidbury: this code is what is used in large IBM mainframes and computers compatible with them typically used by insurance companies and banks for storing their data
drjamessidbury: what do you mean delineate in ASCII?
rtzjm8: how does it distinguish capital vs lowercase
drjamessidbury: By different codes
drjamessidbury: for example A = 01000001 and a = 01100001
drjamessidbury: if you translate these bytes of data into decimal numbers you see that A is 65 and a is 97
rtzjm8: so B is 66 and b is 98?
drjamessidbury: both of these codes use one byte for each symbol so there are only 256 possible symbols that can be represented in ASCII or EBCDIC
drjamessidbury: yes
drjamessidbury: but that's all that';s needed as long as you only use English
drjamessidbury: or Spanish or German or ...
drjamessidbury: but if you go to Chinese or Russian or arabic then the number of different symbols increases substantially
drjamessidbury: not to mention Klingon
drjamessidbury: so for that reason a new code called unicode (not capitalized) use16 bits or 2 bytes for each symbol
rtzjm8: have they come out with an updated Klingon dictionary? haha
drjamessidbury: this gives us 65536 different choices which is enough
drjamessidbury: the downside is that it now takes twice as much space to store things
drjamessidbury: but memory and storage is cheap and with 32 and 64 bit processors that really doens't make much difference
rtzjm8: so now they sell us bigger hard drives
drjamessidbury: my first hard drive was 20 megabytes
rtzjm8: my grandfather's first hard drive was 4K
drjamessidbury: I now have a hard drive that has 1000000 megabytes
drjamessidbury: and it costs less than my first one by a factor of about 10
BB uu GG 22 44: wow
drjamessidbury: so I'm getting 500000 times as much storage for 1/10 the price
rtzjm8: that's amazing!
drjamessidbury: and the new drive is 100 times faster
drjamessidbury: on the other hand when I was in high school, my ambition was to be rich enough to buy a car that costs 10000 dollars
drjamessidbury: there were only about 2 or 3 american cars that fit that specification at the time
drjamessidbury: but enough of reminiscing
rtzjm8: was one a cadillac?
drjamessidbury: yes
drjamessidbury: at my previous teaching job I had a computer of my own
drjamessidbury: and for most of the time that I was there ther were no other faculty members with their own computer
drjamessidbury: and only two students had them
rtzjm8: wow!!!
drjamessidbury: lets talk about compression now
drjamessidbury: compression is the process of taking a set of data and making it smaller
drjamessidbury: for example if you go to my web site you can find a picture of me.
rtzjm8: like zippiing a file.
drjamessidbury: it is about 10K in size
drjamessidbury: the original picture that it was taken from was about 150k
drjamessidbury: there are two kinds of compression
drjamessidbury: lossy
drjamessidbury: lossless
drjamessidbury: with lossless compression the size is decreased in such a way that the original can be gotten back from the compressed version
drjamessidbury: zip is an example of lossless compression
rtzjm8: not practical for websites w/ copyrights
drjamessidbury: why not?
drjamessidbury: I don't see how copyrights have any bearing on this. Explain please
rtzjm8: if you want someone to buy a poster and it is losslessly compressed
rtzjm8: and the user just copies it, then the website's copyright has been violated
drjamessidbury: Oh I see what you mean
rtzjm8: not to mention, they have lost money!
drjamessidbury: but if I take a lossy copy of your poster I've still violated your copyright, I just don't have a very good copy
rtzjm8: true
drjamessidbury: With lossy compression actual data is removed that can't be gotten back so quality is lost
drjamessidbury: but size is really reduced
drjamessidbury: IYKWIM
drjamessidbury: typically pictures, animation/video, and audio are compressed using a lossy technique
rtzjm8: how about videos online that are HD?
drjamessidbury: even HD videos are compressed
rtzjm8: how do they maintain the quality?
drjamessidbury: for example if you go to a movie theater and attend a digital screening of a movie the amount of space that was used to store that movie is very large
drjamessidbury: much larger than a blu-ray disk would be
rtzjm8: OK, got it
drjamessidbury: and as far as the human eye is concerned you can do really good compression of video using techniques like H264 or mp4 or divx which give excellent pictures even in places that they weren't meant to do so.
drjamessidbury: I used a program called handbrake to take a DVD of a movie (it was Batman Begins if you're curious) and converted it to a .h264 file so that I could put it on my iPod Touch to watch while I was on a trip and I couldn't tell that the quality was reduced at all.
rtzjm8: that's cool!
drjamessidbury: In fact I tried to play it on my big screen tv (not HD) and the quality was almost as good as HDTV despite the fact that the whole movie reduced down to about 1.5gb while the original DVD is abou 8
drjamessidbury: I didn't try to compare the copy to the original side by side, but the copy was certainly about as good as watching the movie would have been on TV which is good enough for me and with an iPod screen of something like 3 or 4 inches it certainly sufficed
rtzjm8: sounds very economical
drjamessidbury: Can you tell the difference between a song from a CD that you own (if you own any now) and the same one that you ripped for your computer or portable player?
drjamessidbury: I'm not sure that I can
rtzjm8: not really, only certain songs
drjamessidbury: but I'm really old and my hearing is not as good as it was 25 or 30 years ago
marix3anne: no
BB uu GG 22 44: Do you happen to know a good program to take a DVD and compress it to make a copy on to another CD?
drjamessidbury: and if I'm playing it in the car the outside noise negates any difference and the ear buds for most portable players are not good enough to exploit the difference
rtzjm8: how about the music on itunes?
drjamessidbury: handbrake seems to work reasonably well
borysboy: why don't they just put the compressed versions of the songs on CDs?
drjamessidbury: itunes will rip songs from cds without a problem (at least it does with my CDs but I haven't bought any CD's in the last year probably and the last ones I bought were not recent
rtzjm8: what about the songs on the itunes store?
BB uu GG 22 44: some meatloaf and Jimi Hendrix?
drjamessidbury: people would feel cheated if they put 12 mp3's on a CD when there's room for several hundred
drjamessidbury: and no one would pay 200 dollars for a CD with several hundred mp3s on them
drjamessidbury: I have never paid money to download stuff from the itunes store
drjamessidbury: or any other place
drjamessidbury: I have cashed in some free chits
drjamessidbury: but in general I'm not fond of DRM'd media
drjamessidbury: but that's a topic for another tab
drjamessidbury: I expect that eventually music will be DRM free.
drjamessidbury: the iTUnes store supposedly has most of it free now
drjamessidbury: and they just depend on people learning that stealing is unethical
drjamessidbury: does anyone have any questions about any more of the data topics
PaulinaM2012: nope
marix3anne: no
borysboy: nope
drjamessidbury: we seemed to have toucned on audio and video briefly
rtzjm8: no
BB uu GG 22 44: no
drjamessidbury: what software do you use to rip music or convert video for portables?
borysboy: iTunes
drjamessidbury: how many of you use audio software other than iTunes or Windows Media Player?
rtzjm8: not me
marix3anne: not me
drjamessidbury: I used to use Winamp but don't even have it on any of my computers
rtzjm8: iTunes all the way
BB uu GG 22 44: me too sometimes back in the day
drjamessidbury: there are some files that WMP is necessary for but I typically PLAY most of my video on VLC although I have WMP, iTunes, and QuickTime player
drjamessidbury: the nice thing about VLC is that theres a version for windows and mac and linux and you can play videos while they are being converted
drjamessidbury: ROLL CALL
rtzjm8: Molly Hritzo
borysboy: Jesse Borys

marix3anne: marianne patterson
borysboy: when is the next part of the project due?
drjamessidbury: actually at the end of the semester BUT
drjamessidbury: the Web page is due to be put up in a few days but you wont have the links on it until you have the stuff to put on the links and that;s not due until the end of the month.
drjamessidbury: so I'd say get the page for the project up with a nice background and title
rtzjm8: I finally got my website working!
drjamessidbury: and maybe some pictures or clip art as a start
drjamessidbury: good
marix3anne: what web address should be use for this website?
rtzjm8: Hooray!:-D
borysboy: ok so I'll have awhile to work on it, sounds good
drjamessidbury: the project?
marix3anne: yes
drjamessidbury: basically there will be a link from your homework page to your project page and your project will be on that page
marix3anne: ok
drjamessidbury: I'll do a mock up and give you a link on Wednesday
marix3anne: ok thanks
drjamessidbury: of an example
BB uu GG 22 44: ok
PaulinaM2012: i have two questions: 1) should we put pictures on our regular website? 2) can we "turn in" our website before we put up the project page, or wait until afterwards?
rtzjm8: what if I already put something up?
drjamessidbury: yes the web site should be 'turned in' as soon as the basics are done
rtzjm8: Not the finished project of course!
drjamessidbury: you will be changing the two homework pages during the semester
rtzjm8: Should we email you or just tell you now
borysboy: what do you mean 'turned in'?
drjamessidbury: e-mail me
borysboy: ok
drjamessidbury: i;m on my vista computer and my gradebook is on my os x computer
rtzjm8: ok
PaulinaM2012: and should there be pictures on our regular old website?
drjamessidbury: 'turned in' = put whatever stuff you're putting on your Web site and then sending me an e-mail telling me that it's there and ready to be graded.
drjamessidbury: pictures are not necessary for the regular old web site
drjamessidbury: but
drjamessidbury: if you put some there
drjamessidbury: then your ROW will be better and may get bonus points
rtzjm8: our what?
drjamessidbury: Regular Old Website

rtzjm8: haa
drjamessidbury: CISD
borysboy: ok so I'm using fetch now, and I got into the cil.cs.scranton.edu and there's only 1 folder called public_html
borysboy: where's my folder?
rtzjm8: u have to transfer them in.
drjamessidbury: so double click on that folder and that should put you in the web site folder
drjamessidbury: then just grab the files from wherever they are on your computer and drag them in
borysboy: I have a webpage in there
drjamessidbury: just be sure that the sftp or port 22 is turned on
borysboy: but my website is not showing up
drjamessidbury: then it's not there
borysboy: it's in public_html folder as an HTML document
drjamessidbury: what is its name?
borysboy: My Web Page.html
marix3anne has left the room.
drjamessidbury: it's got to be named index.html (no caps)
borysboy: oh ok i'll change it
drjamessidbury: that's what the Web server is expection
drjamessidbury: you can use Fetch to do that
drjamessidbury: btw did you get back to me about myITLab?
rtzjm8: BTW, thanks for sending the windows to me.
rtzjm8: I really appreciate it
borysboy: about macs using myITlab?
drjamessidbury: don't forget to send a copy of the signed doc
drjamessidbury: yes
borysboy: yea I have XP on my computer
rtzjm8: I will.
rtzjm8: didn't get it yet
drjamessidbury: virtualized or boot camped?
drjamessidbury: or both?
borysboy: both
drjamessidbury: how virtualized?
borysboy: virtualized normally runs to slow to do complex programs
borysboy: parallels
borysboy: I mainly use it just to transfer files
drjamessidbury: it should probably work for doing myitlab since it runs under IE 6 or 7 and the speed slow down is due to the internet not to the system
drjamessidbury: parallels 3 or 4?
drjamessidbury: I just got a cheap copy of 4 that I haven't tried out yet
borysboy: I have 3.0
borysboy: idk if it's even updated
borysboy: how much was 4.0?
drjamessidbury: supposedly the new version is better but when it came out the consensus is that it had lots of errors and crashed all the time
rtzjm8: quick question
drjamessidbury: I went to macupdate.com they had a special fo 11 programs for 50 dollars one of which was parallels 4
rtzjm8: is there a way to set a pic as a background in nvu?
drjamessidbury: you might look there and see if the special si still going on
drjamessidbury: yes
rtzjm8: ok thanks
drjamessidbury: go to the code portion and put a line in the style that says
drjamessidbury: http://www.w3schools.com/css/tryit.asp?filename=trycss_background-image
borysboy: ok my webpage finally works
drjamessidbury: here is a link that tells you how to do it
drjamessidbury: good
rtzjm8: thanks!
borysboy: ok I'll finish it up, thanks, good night
rtzjm8: Have a good night!
drjamessidbury: www.w3schools.com is a good web site that tells you how to do a lot of stuff with web pages
