Today’s tip deals with portable data storage. Most of the work we do
on computers around here is meant to be viewed by someone else, either
students, supervisors or colleagues. However, getting these people to
come behind your desk to watch something is probably not what you had
in mind. So your data needs to be portable.
There are several options for this and the theme that will run through today’s tip will be to use multiple paths to ensure that you have your data when you need it. CDRs and Zip drives will be compared to the USB Key drive.
The neatest gadget that you can use is a USB Key drive. These are little plastic keys that plug into the USB port of any modern computer. It is recognized by the operating system as just another hard drive in your computer. You can now copy to this drive as well as edit, delete and add to it. Here is a list of things you can do with a USB Key that you cannot do with just a CDR.
Well here is a comparison of the USB Key to a zip drive
The server is backed up frequently. So data that makes it to the server should be fairly secure. However, if you have large files and a slow connection at home, it is just not worth waiting hours for data that could be carried on a USB key and loaded in minutes. If you have no network connectivity at home, OneNet is not even an option.
Yes, size matters. CDRs will hold 640 megabytes (megs) of data. Zip disks will hold either 100 or 250 megs of data. USB Keys can hold anywhere from 16megs to 4000 megs (4 gigabytes). The current price break seems to be around the 128meg or the 256megs size right now as these sizes can be had for between $20 and $40 dollars (August 2004)if you shop the sales some.
They are not just storage devices. You can buy USB Keys with audio capability which turn them into a solid state walkman or a digital voice recorder. The Walker Teaching Resource Center (Karen) had a model that not only stores data, but also had a radio linked button set and a laser pointer. This allows her to carry her powerpoint presentation to a podium computer, advance the slides with the remote buttons and point out key points with the laser. Sort of an all-in-one presentation package. Here is a link to some of those.
So look at a USB Key next time you need to carry data with you. They are pretty convenient.
There are 4 supported ways to upload or download your files to your OneNEt file storage space. Each faculty is given 200 megabytes of space on OneNet but you can call the help desk and ask for more if you need it. As usual, each of the following methods of accessing your space has draw backs and advantages. By knowing which method does what, you can pick the way that works best for you.
Go to Onenet web site and log in with your OneNet username and password.
Pros - This interface works from anywhere on the web. It works with a wide variety of web browsers and has a good reliability history.
Cons - This method only allows you to upload and download one file at a time. If you are dealing with a large number of files, this will take a long, long time.
Using Internet Explorer, go to the following web address, ftp://oneftp.utc.edu/
A windows should pop up and ask you for your OneNet username and password.
Pros - Makes your Internet Explorer act just like your Windows explorer. You can copy and paste multiple files and directories fairly easily.
Cons - Does not work with other browsers. Remembers your login until you close the browser.
Type in the server name of oneftp.utc.edu and this program will connect OneNet as just another hard drive on your computer.
Pros - Any server can be attached as just another hard drive on your computer. This allows all programs to open and save to this new hard drive while in actuality; the data is being uploaded to the server. Really easy to work with. You can copy and paste multiple files and directories fairly easily.
Cons - This program has had issues with reliability. Sometimes it works perfectly other times, something hangs in the system. It only works with Windows machines
OneNet is a Novell program. This is the Novel program to connect your server space as another hard drive.
Pros - Because it is a Novell native program, this is the fastest way to upload and download files to the server. It is 4 to 10 times faster than the above methods. It is easy to use as the server appears as just another hard drive on the computer. You can copy and paste multiple files and directories fairly easily.
Cons - It only works from campus. The other
programs will work from anywhere. It completely takes over your
login process to Windows. If it stops working, you cannot even
get into your computer. It has had a few reliability
issues. It only works with Windows machines. It only works with
Novell servers (OneNet is a Novell server but most of the others
servers on campus are not. Juno, Ulysses, etc) (added 3-29-04)
Did you know that you can access your email in a variety of different ways? Our UTC email server can handle several connection methods and each one has various attributes that will help you access your email in the manner you want.
There are two main protocols that are used to connect to the UTC email server, IMAP and POP3. IMAP stands for Internet Message Access Protocol and POP3 stands for Post Office Protocol revision 3 and is the older of the two. POP3 was designed to go get your email and then delete it from the server and it does this really well. IMAP was designed to work with your email on the server, so it allows you to create subdirectories and to move email around into these subdirectories on the server. Added 10-13-03
This is the simplest method of getting email. All that is required is a connection to the internet and your computer can pick up your email from your inbox on the email server (pop.utc.edu). As soon as your computer has your email, it is deleted from the server making room for other email. All of your email is stored on your own hard drive. This works wonderfully if you only want your email going to one computer. It is a problem though if you want to be able to get your email from several computers or see it from the web-mail interface of OneNet. The emails are no longer on the email server after they are downloaded (POP’ed) to your computer. The POP3 protocol can be manipulated a little bit by delaying when emails get deleted or by picking only one computer to delete the email and the rest that you use to just copy them. So other computers have a chance to retrieve a copy, but you still are not assured that all computers will have all emails.
Email stays on the email server (imap.utc.edu) and you just connect to it from any computer to read them. (IMAP protocol) This is a great method of being able to see your email from lots of different computers. You can check your email from the office, from home and from on the road using the Web-Mail interface of OneNet. You can even have subdirectories on the server in which to file your email. The main problems with this method are that all the messages are stored on the server taking up a limited amount space. If you are the type of person who deletes emails often, this is not a problem. If you happen to want to be able to refer back to old emails, you may run into storage space issues by saving all of your old emails on the server. This is especially true if you receive a lot of attachments in your email. Added 10-13-03
You can also choose to only work with your email using the web
interface that is part of OneNet. This system uses the IMAP protocol
similar to the way an email program on your personal computer would.
Web-Mail allows you to create subdirectories on the server and to
create rules to sort incoming mail into these subdirectories. This
system allows you to see your email from any computer that has a World
Wide Web connection. The drawbacks are the same as that for using IMAP,
namely storage space concerns, as well as a possible lack of features
that you could find in another email program that runs from your
desktop (spell check).
Problem: Your data is up and down and you need it side to side.
Do you know how to transpose a column of data in Excel to a row of data?
1. Select the cells you want to copy
2. Choose Edit>Copy (or ctrl-C)
3. Right click on the cell that you wan the data to start in.
4. Choose Paste Special and choose ‘Transpose’ then click OK.
Copying from a column transposes to a row. Copying from a row transposes to a column.
**** You can also use paste special to copy formulas and transpose them. If the formula refers to the cell above the original cell that you copied, it will transpose to referring to the cell to the left of the new cell into which you paste.

Problem: What you see on your screen is not what you see on your printed page.
So you are using the new WebASIS system but when you try and print something like your class rolls it seems to garble the output. What you see on the screen is not what you see on the page. This usually means that the font has been set for easy viewing on the screen and not good printing on the page. Try making the font size smaller and then choose print preview to see if it has done any good. This should correct most print formatting issues.
In Internet Explorer, go to View > Text Size and choose a smaller size. Now go to File > Print Preview and see what it looks like.
In Mozilla, go to File > Page Setup and choose Shrink to fit page width. Now go to File > Print Preview and see what it looks like.
