Caller ID Can Be Hacked
If you rely on caller ID to screen calls, you should be aware that the number you see cannot always be trusted.
There are a few services available that let people choose the caller id number that appears when they make a phone call.
Telemarketers and collections agencies are not allowed to change their number, but some still do.
I share this secret because caller id spoofing is becoming popular among fraudsters. You should be weary of any caller asking you for something, especially money or personal information. If a caller claims to be from your financial institution or another company that requires personal information, ask them some information that confirms they are who they say they are. For example, if it’s your cell phone company, ask them which calling plan you’re on.
How to Get the Best Price When Shopping Online
The internet has completely changed bargain hunting and finding the best price couldn’t be any easier.
I like to use Google products (formerly known as “Froogle”). It compares prices at thousands of retailers and show you the best deals along with ratings for each retailer.
Google products also searches sites like ebay. Although, it’s worthwhile checking ebay independently, there are lots of auctions for new products or if you’re willing to take a used one then you’ll get a great deal. If you’ve looking for something that doesn’t ship well, such as appliances, be sure to check craigslist.org or kijiji.com (owned by ebay). They let you search for products in your area so shipping is not necessary.
Sometimes the best price is at a website you’ve never heard of. This is when customer ratings and common sense are really helpful. If you’ve never heard of the retailer and can’t find a phone number for the office on the site, then I probably wouldn’t order from them. Amazon might be the only exception to this and in fact they’re one of my favorite online retailers, they frequently have the best price and their shipping and customer service are great.
If you’re searching for cameras, be weary of small companies based in New York City. They usually have the best price on camera equipment, but there are lots of online horror stories about some of these companies.
Rescue a Disc From Your CD Drive With a Paperclip
Most CD/DVD drives in computers have a secret eject button. It allows you to open the CD drive when a disc gets stuck and cannot be ejected normally. It’s also helpful if you need to remove a disc and you don’t want (or have time) to power up the computer — the force eject works without power.
You’ll need a thin sturdy object to operate the manual eject, a straightened paperclip works well. In rare cases, the hole will be slightly smaller than a paperclip and a sewing needle will be required.
Look for a round hole on the face of the CD drive that is just large enough to feed a paperclip through. The following photos show the manual eject hole on a desktop and laptop CD drive.
Once you have found the hole, push a straightened paperclip through the hole and when you feel it stop, push a little harder and it should push open the motorized drive tray (desktop) or release the drive lock (laptop).
If you’ve got a Mac, most new models have a slot load drive (there is no tray that the disc sits on, similar to most car CD players). Some of these drives are particularly bad at ejecting CDs with uneven edges (if yours does this then you’ll know what I’m talking about) and there is a paperclip method for these drives too. There is an Apple support document for this issue; you’ll have to click here to view it since I can’t use their material.
Maybe you’ve seen that hole and wondered what it was for, maybe not. Frankly, it doesn’t matter, because you know now and that’s what we do here.

How To Make Your Laptop Battery Run Longer
When your laptop is new, you can run on battery power for hours! But, as the battery gets older it doesn’t hold a charge like it used to. Ideally, you would just buy a new battery, but laptop batteries are expensive. From the manufacturer, they range from $80 to $150. Aftermarket batteries are often 50% – 70% of the manufacturer’s price. I’d recommend searching eBay or Amazon for new aftermarket batteries.
If you buy a new battery, keep your old one. I used to travel almost every week for work and I always had a second laptop battery with me. At times, the second battery was old, and only ran for 45 minutes, but that was a lifesaver on an airplane when you’re trying to finish some work (or watch the end of a movie you brought).
I usually buy the aftermarket batteries and never have problems with them. I did have a problem with an aftermarket power supply cord once; it died after three months. But, even with that $13 loss, buying aftermarket laptop accessories has saved me a lot of money over the years.
If you travel a lot, a second power cord is paramount. You should have one that you always leave in your computer bag, that way it’s impossible to leave behind when you travel. Have you ever tried to find a computer power cord at a retail store? If you are lucky enough to find one, it’s going to cost at least $60. If you can’t find one, and you need one for work — it’s a disaster. (more…)
Your Eyes Adapt to Darkness In 20-30 Minutes
If you’ve shopped for an HDTV, you’ve probably seen something on the spec sheet called “contrast ratio.” Contrast ratio is the difference between the darkest and brightest picture a TV can produce. Contrast is important to a good picture.
That’s because our eyes can recognize a contrast difference of 1,000,000,000:1. That means, the brightest thing our eyes can see is a billion times brighter than the darkest thing. Good contrast to your eyes is like a gourmet meal for your taste buds. Contrast adds a lot of detail to the picture and ultimately immerses you in the action.
Unfortunately, when shopping for TVs, contrast ratio is almost meaningless. It could be really useful, but all of the manufacturers measure this number differently and then call it the same thing — it’s really only useful when comparing two TVs from the same manufacturer.
Imagine you want to buy a new car: you are cross shopping three manufacturers who measure fuel economy in three different ways. The first one, measures fuel economy while driving down a hill, while the other two measure it on flat land and while driving up a hill. Obviously, you can’t compare the results of those tests. But, if you’re looking at two cars from the same manufacturer then there is some comparative value to those numbers, even though they may not be accurate in a typical situation.
Thankfully, our eyes are extremely sensitive to contrast. Turn both TVs on and look at a flat black image for a while. A flat black image makes it easy to spot variations in darkness (aka “banding”), no banding should be present in a good TV. If you still can’t tell the difference and they both look good, then the difference is too small to worry about. Trust your eyes, they are incredible instruments.
It takes 20-30 minutes for your eyes to adjust from one extreme to the other because the contrast ratio is so high. If you’re in bright sunlight and then walk into a very dark room, it will take 20-30 minutes before you can see your best in that room. If you are in a moderately bright room and go into a very dark room, it is often closer to 15 minutes.
The rods and cones in your eye are tested during dark adaptation. Rods are more sensitive to light and take longer to adjust. Cones are much faster to adjust, often in approximately 9 minutes. People over the age of 50 need twice as much light to see as well in the dark as a 30 year old. So, if you need more light, consider my CF light secret.
Frequent fliers will eventually notice that the aircrew dims the airplane’s interior lights on final approach during night landings . They want your eyes to be adjusted to the darkness outside in case the landing does not go as expected and you have to evacuate the plane.

Google Provides Free 411 Searches and Connections
Google has a lot of cool services that most people don’t know about. One of my favorite Google secrets is Google 411.
Just dial: 1-800-GOOG-411
It is just like your local telephone company’s 411 service, except it’s free and it automatically connects you to the number for free. It works from US or Canadian phones and can be used to find US and Canadian business listings.
It also has some cool features. When you find a listing, you can say “text message” and Google will instantly text you the phone number, address and a map link for the address that opens in Google maps on a capable phone.
There are even cordless phones available with a dedicated button for Google 411.
Remember goog-411 the next time you need to make dinner reservations or order takeout — it couldn’t be easier or cheaper.

Automatically Add WWW. and .COM to a Website Address
Because I spend so much time on the internet, I have bookmarked hundreds of websites, maybe thousands. They’re neatly organized into folders by category, some of them 8 folders deep. But, I rarely see anyone else use bookmarks — I know that you’re typing in the address for many of the sites you visit.
This secret will save you some keystrokes.
Instead of typing “www.BrokenSecrets.com” and then hitting enter, just type “BrokenSecrets” and press CTRL+ENTER (Mac users use COMMAND + RETURN). That will automatically add “www.” to the beginning and “.com” to the end.
For those who have no idea what I’m talking about, look at the top of your web browser (the program you’re using to view this site). You’ll see a text input area that starts with, “http://brokensecrets.com”. That is where you can type web addresses that you’d like to visit. For most sites, you need to at least type the address and the extension (ex: brokensecrets.com).
In Windows, this works with: FireFox, Internet Explorer and Chrome. On Mac, this works with FireFox and Chrome, but use CTRL + RETURN for Chrome. It does not work in Safari for Mac or Windows.

Web Browser Secrets
Based on the results in the video below, I should start by clarifying that a web browser is a piece of software that you use to view web pages. The top three browsers are: Internet Explorer (Microsoft), Firefox (Mozilla) and Safari (Apple). Google’s browser (named “Chrome”) is a close fourth. There is a 98% chance that you’re using one of these browsers to view this page right now.
Browsers are commonly confused with search engines, which are just web pages that you view using your web browser software. That’s obviously not a surprise to some of you, but like it says in the Google video below, it is a secret to almost 90% of people.
Knowing some browser tricks will make this tool work much better for you.
Modern browsers have tabs, which promote easier multitasking. There are a few ways to perform the tasks listed below, but here are a few of the best (and least used) tricks for managing tabs in the top three browsers mentioned above.
Managing Tabs
- Open new tab: double click on empty area of tab bar
- Close tab: middle click anywhere on the tab (does not work in Safari)
- Open link in new tab instead of replacing current page: middle click on link (instead of left click)
Because we spend a lot of time reading text in our browser, there are a couple of features built in to make reading easier. Try these keyboard shortcuts right now.
Reading
- Scroll browser down exactly one page: spacebar
- Scroll browser up exactly one page: shift + spacebar
- Full Screen Toggle: F11
- Zoom In (make text larger): ctrl + scroll mouse wheel up
- Zoom Out: ctrl + scroll mouse wheel down
