Computer Info – March 6, 2002

 

This Week’s Program

            Nell Franzel will demonstrate her Palm Pilot and the software that you use on the computer.  The remaining time will be used for our usual question and answer session.

 

eBay.Com

http://www.ebay.com

 

            eBay is a public auction site.  If you wish to learn more about it – look for the LEARN MORE button near the top of the page where it says Welcome New Users.  You can learn how to FIND items by name or category – learn how to BID on an item (you must be REGISTERED first) – learn how to SELL (again you must be registered and set up an account) – learn why eBay is SAFE to use (check a seller’s business practices – it has an escrow service where your money can be held until you inspect the merchandise).  But you do not have to be registered in order to browse the site to see what is being auctioned.

            Look through a category or search for a particular item.  When you find it, click on it to get more details.  From here you can see what the latest bid is, how long before the bidding will be completed, type of payment accepted, how shipping charges are applied, a description of the item, sometimes a picture of the item and many other details.

            Look for the BUY IT NOW icon.  This indicates that if you decide to buy it now, the bidding will stop as long as you meet the BUY IT NOW price. 

            The fee for using eBay is paid by the seller and it is based on the opening bid plus one percent of the total bill.  Look for the padlock (which denotes security) when entering your credit card information.  PAYPAL is one of the methods you can pay for your purchase – you can set up an account at  http://www.paypal.com 

 

PDA (Personal Digital Assistant)

            Personal digital assistants include the Palm Pilot.  These are devices that can be used for storing and editing an address book – a calendar – a TO DO list.  It can also be used for playing games – editing Word or Excel documents – connecting to the internet and retrieving your e-mail – and many other programs that are available.

            Information is entered into the PDA from a stylus by means of a menu or alphabet icons or graffiti (which is an abbreviated form of handwriting) – or with an attached keyboard that can be purchased for PDA’s - or entered into the program that is loaded onto your computer – or beamed (transferred via IR – infrared).

            It can be connected to a computer to transfer the information from the PDA to the computer – or from the computer to the PDA – or both.  It is connected to the computer via a USB cable.  For those that do not have a USB port, a serial cable can be purchased. 

            Transferring the data between the PDA and your computer is done via the HOTSYNC button on the PDA or the menu in the computer program.  Take for instance, the address list.  If you make changes to the record of JOHN SMITH on the PDA and then make changes to the record of ROBERT JONES on the computer, when you perform a HOTSYNC, the updated John Smith record will be moved to the computer and the updated Robert Jones record will be moved to the PDA.  So you can see that the information is in SYNC.  If you were to make a change to the record of PHIL BROWN on both the computer and the PDA – then both records for Phil Brown would be placed on the computer and the PDA.

            The information in the address list can be EXPORTED as a Comma Delimited file.  This type of file can be opened in EXCEL or other types of databases (like the Personal Address List that we demonstrated a couple of months ago) or Outlook Express.

 


Inoculate Anti-Virus

            One of our members informed us that Inoculate Anti-Virus was no longer going to support (or update) their anti-virus program and their users would have to find a new anti-virus program.  You can read about it at   https://www1.my-etrust.com/services/ipe_support

 

Printing Web Pages That Contain Frames

            Click on the screen area of the frame that you wish to print.  Then when you bring up your print menu, be sure to choose PRINT THIS FRAME.  This should work the same in Internet Explorer and Netscape.

 

Copperfield.PPS

            If you were at last week’s meeting and saw John Watkins demonstrate the Copperfield powerpoint show – you will find that you can download it from his web site at  http://www.hdprint.co.uk/ftp  in the folder for FUN STUFF.  This is a card trick by David Copperfield.

 

Steganography and Digital Watermarking

The technique, known as steganography, is the practice of embedding secret messages in other messages -- in a way that prevents an observer from learning that anything unusual is taking place. Encryption, by  contrast, relies on ciphers or codes to scramble a message.  

Steganography is being used to hide information in BMP and JPG pictures or MP3 music files or in the white space at the end of a text file.  These are also potential places to hide viruses.  This method of hiding information has also been linked to Osama Bin Laden early in 2001.

This is just a brief message about it just to inform you as to what can be done.

 

Cleaning Your Mouse

This still seems to be a problem that people are not understanding.  When your mouse begins to act erratically (when you have a hard time moving your mouse to the position that you would like) – then it is definitely time to clean it. 

            To clean your mouse – turn it upside down.  Rotate the circle around the ball to loosen and remove it.  The ball is NOT to object that’s needs cleaning.  Most of the time, it is pretty clean.  What you need to clean are the little rollers inside the mouse where dust has accumulated on (and wrapped around).  There should be three different rollers.  Use a toothpick to try to dislodge it and then blow it out.  You will find that your mouse behaves much more smoothly.
