Reporter’s Comments:

 Our Club will not be active this summer because it is just too hot, and many members have gone to cooler climes. I have been in and out of town so I have had to combine our May & June issues of the Newsletter. As you see below, Mr. Modem is still pumping out his Pearls of Wisdom on time, every month.

As a reminder, I am copying the tip offered in our March Newsletter.

 “The March 17th Newsweek magazine has a very good article entitled “Get ready for Digital”. I thought you might be interested in a brief outline of the article. Those of us who use “Free” TV, have until February 17th 2009 to convert to the High Definition Digital Signal. You may receive a maximum of two $40.00 coupons from our government by visiting …… http://dtv2009.gov.

 For a list of the approved boxes, which range in price from $ 40.00 to           $ 70.00, visit http://ntiadtv.gov/cecb_list.cfm . These boxes are available from retailers like Wal-Mart, Radio Shack and Best Buy. 

The article concludes that the majority of the salespeople are woefully unprepared to give good, accurate information, and they suggest that consumers do research ahead of time by visiting the following sites http://dvt.gov.dtvanswers.com and http://dtvtransition.org.”

 

I have sent for my coupons. It takes about three weeks to receive them.  I understand I have 90 days from the mailing date to use them.

The Mouse in Your House: Laser or Optical?

Q.  When I attempt to enter some sites, I have to type some weird numbers or words that appear in a box.  The letters and numbers are so difficult to read, it usually takes me about three attempts before I get it right. I know it’s for security, but how does typing in those numbers actually help anything?


A. Those characters appear as an image, rather than plain text, in order to prevent what are called spambots (robotic programs), using a computer script, from copying and pasting those characters into the fill-in form. The numbers are distorted to prevent optical-character recognition software from reading them. Only the human eye can decipher the characters, thus ensuring that the site or service is only accessed by human beans (homosapiens legumous), not robotic programs.

Some sites offer an audio link that “speaks” the characters, which can then be typed into the form. The theory is the same, though, that only humans will be able to listen to the audio and type in the numbers correctly.



Q.  I was mouse shopping the other day and looked at both a laser mouse and an optical mouse. I bought the laser mouse, but now I’m not sure if I bought the right thing, so I’m turning to you, Mr. M:  What’s the difference between an optical mouse and a laser mouse, and is one better than the other?

A.  The difference between an optical mouse and a laser mouse is the light used to track movement. An optical mouse uses an LED (light-emitting diode), while a laser mouse uses a -- care to venture a guess?  That’s right, a laser. The more dots per inch (dpi) a mouse can track, the more sensitive and accurate it is. A typical optical mouse tracks between 400 and 800 dpi, while laser mice track more than 2,000 dpi.

Neither is really better; it all depends on your needs and preferences. Unless you're a gamer or a graphic artist with a need for super-precise movement, you'll probably find a 2,000 dpi laser mouse overly sensitive, but that’s the primary difference.  An optical mouse would have served your purposes very well, but you didn't purchase the "wrong" mouse unless you find its sensitivity to be excessive.  Many gaming mice (lasers) allow sensitivity adjustments so you can have precision when you need it, but can revert to 400 dpi or 800 dpi for regular mousing activities. Check the documentation or Help files in conjunction with your laser mouse to determine if you have that capability.  

Besides tracking speeds, laser mice work on nearly every surface, where optical mice may occasionally experience difficulty tracking on black or shiny surfaces. I use an optical mouse, but have never had a problem using it on any surface.

Eli Stein Cartoons
For more than 50 years, Eli Stein cartoons have graced the pages of many prestigious publications, including The Wall Street Journal, The National Law Journal, Barron’s, Better Homes and Gardens, Good Housekeeping, The Saturday Evening Post, King Features Syndicate, Modern Maturity, National Enquirer, Woman’s World, and National Review, just to name-drop a few. Cartoons are categorized by decade (beginning in the 1950’s), publication or topic. And if the brilliance of his cartoons isn’t enough, Mr. Stein’s insightful, humorous comments and recollections accompany many of his works.

OR Live
This site was launched approximately eight years ago as a way for physicians and surgeons to bone up on new techniques by logging on to watch their peers perform various surgeries. Recently, the site has been attracting many patients who, understandably, are also curious about procedures. Categories of surgeries include Cardiovascular, OB-GYN, Orthopedics, Pediatrics, and other specialties. Most videos require RealPlayer, but you’ll be prompted if your system is lacking the necessary program to view a given procedure.

Pets on the Go
Do you like to travel with your pet? If so, this site is the definitive guide for information and links to more than 30,000 pet-friendly hotels, inns, B&Bs, and private rentals. The “Tips for Trips” section provides some great information if you’re planning to fly with Fido, cruise with Kitty, or surf with Sushi. (Okay, okay, I couldn’t think of anything else.)

Ask Mr. Modem! – June 2008

Save Data With Proper Windows Shut Down

Q.  What is the reason for exiting out of programs before shutting down my computer? What happens if I don’t?

A.  Unless you enjoy living on the digital edge, exiting out of programs permits each program to shut down in a specifically designated manner, which includes saving your data and tidying up before closing. 

For example, many programs create temporary files while being used. These files are deleted during the course of the program’s shut-down process. Some programs that contain a “Deleted Items” or “Trash” folder will empty these folders upon closing, as well. 

If you fail to close programs before shutting down your PC, it may, under certain circumstances, result in the loss of data, so it’s always best to close programs first.

For the most part, Windows will automatically close open programs as part of the overall shut-down process. If Windows isn’t shut down properly—for example, if you press the power button on your computer or (gasp!) yank the plug out of the wall—the next time you start your computer, it will run through a series of additional tests to verify the integrity of your data, as well as take a look around to be sure everything is functioning properly. 

All things considered, it’s best to shut down your system as Mr. Gates requests, via Start > Turn Off Computer. It only takes a couple of seconds, so better safe than sorry.


Q.  Is there any maximum length for an email address?

A.  A username (the first part of an address, before the @ sign) can be up to 64 characters, which is much less than the domain part, which can be 255 characters. That means the total maximum email address length can be a staggering 320 characters.  (Why characters would be staggering is unknown.)

A 320-character email address would (320) be unbelievably annoying to anybody who has to manually type the address. To understand just how lengthy that would be, this question and answer, up to the parenthetical (320) in the previous sentence, is 320 characters. 

Realistically, any email address that long is going to continually run into problems with mail servers and email programs. Even the Microsoft Access database only permits a maximum of 50 characters for an email field.

When it comes to Internet protocols, there is always a gap between what is permitted and what is supported.  Shorter email addresses are desirable for a number of reasons, not the least of which is that they’re easier to remember and use on a daily basis. 


Q.  How do I show more than one window when viewing Web sites?

A.  The specific steps for opening additional windows to view multiple Web sites or pages depends on your browser, but generally, CTRL + N will open a new browser Window. When the new window opens, type in or paste a Web site address and press Enter to navigate to another Web page. You can continue to press CTRL + N to open as many windows as you wish.

If you’re using Internet Explorer 7, Opera or the Firefox browser, press CTRL + T to open new tabs, within which you can navigate to additional sites.

Analytical Problems and Puzzles
The first thing you’ll have to do upon entering this site is choose your challenge: Lateral Thinking or Logic Problems. I was stumped right there.  Next, select a level of difficulty ranging from Very Easy to Very Difficult. These are excellent exercises for the brain, though my few remaining neurons didn't find the very easy ones to be particularly easy. Humbling? Yes; Easy? No. Here’s an example of a “very easy” question:  “How could a baby fall out of a twenty-story building onto the ground and live?” Hint: You’ll find the answer in the Lateral Thinking section.

Hard-to-Find 800 Numbers
If you have ever tried to find an 800 number for a product, service or company, you know the meaning of frustration. This site provides a comprehensive and convenient reference for that purpose. Interestingly enough, the most frequently sought 800 numbers, are for Amazon, eBay, PayPal, Yahoo, and Microsoft.  (I said it was interesting, not life-altering.)

Plot-O-Matic
Have you every watched a movie and thought to yourself, "I can write a better movie than this piece of predictable fluff"?  Well, you probably can. And it's easier than you might think. Just select the characters and plot elements you want to include in your movie, then click the “Lights! Camera! Action!” button.
