9 things that will disappear in our lifetime??

Whether these changes are good or bad depends in part on how we adapt to them. But, ready or not, here they come.

1. The Post Office
Get ready to imagine a world without the post office. They are so deeply in financial trouble that there is probably no way to sustain it long term. Email, Fed Ex, and UPS have just about wiped out the minimum revenue needed to keep the post office alive. Most of your mail every day is junk mail and bills.

2. The Cheque
Britain is already laying the groundwork to do away with cheque by 2018. It costs the financial system billions of pounds a year to process cheques. Plastic cards and online transactions will lead to the eventual demise of the cheque. This plays right into the death of the post office. If you never paid your bills by mail and never received them by mail, the post office would absolutely go out of business.

3. The Newspaper
The younger generation simply doesn't read the newspaper. They certainly don't subscribe to a daily delivered print edition. That may go the way of the milkman and the laundry man. As for reading the paper online, get ready to pay for it. The rise in mobile Internet devices and e-readers has caused all the newspaper and magazine publishers to form an alliance. They have met with Apple, Amazon, and the major cell phone companies to develop a model for paid subscription services.

4. The Book
You say you will never give up the physical book that you hold in your hand and turn the literal pages. I said the same thing about downloading music from iTunes. I wanted my hard copy CD. But I quickly changed my mind when I discovered that I could get albums for half the price without ever leaving home to get the latest music. The same thing will happen with books. You can browse a bookstore online and even read a preview chapter before you buy. And the price is less than half that of a real book. And think of the convenience! Once you start flicking your fingers on the screen instead of the book, you find that you are lost in the story, can't wait to see what happens next, and you forget that you're holding a gadget instead of a book.

5. The Land Line Telephone
Unless you have a large family and make a lot of local calls, you don't need it anymore. Most people keep it simply because they've always had it. But you are paying double charges for that extra service. All the cell phone companies will let you call customers using the same cell provider for no charge against your minutes

6. Music
This is one of the saddest parts of the change story. The music industry is dying a slow death. Not just because of illegal downloading. It's the lack of innovative new music being given a chance to get to the people who would like to hear it. Greed and corruption is the problem. The record labels and the radio conglomerates are simply self-destructing. Over 40% of the music purchased today is "catalogue items," meaning traditional music that the public is familiar with. Older established artists. This is also true on the live concert circuit. To explore this fascinating and disturbing topic further, check out the book, "Appetite for Self-Destruction" by Steve Knopper, and the video documentary, "Before the Music Dies."

7. Television
Revenues to the networks are down dramatically. Not just because of the economy. People are watching TV and movies streamed from their computers. And they're playing games and doing lots of other things that take up the time that used to be spent watching TV. Prime time shows have degenerated down to lower than the lowest common denominator. Cable rates are skyrocketing and commercials run about every 4 minutes and 30 seconds. I say good riddance to most of it. It's time for the cable companies to be put out of our misery. Let the people choose what they want to watch online and through Netflix.

8. The "Things" That You Own
Many of the very possessions that we used to own are still in our lives, but we may not actually own them in the future. They may simply reside in "the cloud." Today your computer has a hard drive and you store your pictures, music, movies, and documents. Your software is on a CD or DVD, and you can always re-install it if need be. But all of that is changing. Apple, Microsoft, and Google are all finishing up their latest "cloud services." That means that when you turn on a computer, the Internet will be built into the operating system. So, Windows, Google, and the Mac OS will be tied straight into the Internet. If you click an icon, it will open something in the Internet cloud. If you save something, it will be saved to the cloud. And you may pay a monthly subscription fee to the cloud provider. In this virtual world, you can access your music or your books, or your whatever from any laptop or handheld device. That's the good news. But, will you actually own any of this "stuff" or will it all be able to disappear at any moment in a big "Poof?" Will most of the things in our lives be disposable and whimsical? It makes you want to run to the closet and pull out that photo album, grab a book from the shelf, or open up a CD case and pull out the insert.

9. Privacy
If there ever was a concept that we can look back on nostalgically, it would be privacy. That's gone. It's been gone for a long time anyway. There are cameras on the street, in most of the buildings, and even built into your computer and cell phone. But you can be sure that 24/7, "They" know who you are and where you are, right down to the GPS coordinates, and the Google Street View. If you buy something, your habit is put into a zillion profiles, and your ads will change to reflect those habits. "They" will try to get you to buy something else. Again and again.

All we will have left that can't be changed are "Memories", and then probably Alzheimers will take that away from you too !

What's best for my computer: Hibernate, sleep, or shut down?

Q: Does putting my computer to sleep help extend the battery life? What else can I do to save energy and make my new computer last?
A: We’ve all heard stories about what's best for a computer’s battery. That’s why I was excited to make friends with Fred Peters, president of Huntington Beach IT Services.
In addition to teaching computing courses in Orange County, Calif., Peters happily makes house calls to revive frazzled computers and the people who rely on them.

Here are his expert tips on how to keep your new laptop running smoothly.
Sleep mode vs. shutting down
Peters notes that your work process will determine whether it’s more efficient to use “Sleep” mode or simply shut down the computer. “It is never fun to have to consistently wait any amount of time if the shut downs are too frequent,” he says. "‘Sleep’ requires more power, but it boots up faster, while ‘Hibernate’ uses less power, but takes longer to come online.” That same logic applies to shutting off your computer completely.
“Your computer will become obsolete before you wear out your computer by turning it on and off a lot,” he adds. “It also doesn't take more energy to start a computer than to keep it running.”
Sleep mode requires a constant, though reduced use of power (0-6 watts). Peters also notes that colorful screensavers do nothing to conserve energy. Accessing your computer remotely with the Wake on LAN feature also can drain the power.
To get the most for your money, Peters advises adjusting power settings so that it automatically goes into Sleep/Standby mode after about 15 minutes of inactivity, and then shut it down at the end of your day.
Bionic battery life
To get the most out of your computer battery, Peters says to you have to give it a workout. Don’t keep your machine plugged in to an outlet. Instead, discharge the battery daily.
Size does matter
By purchasing a laptop, Peters says that you are ahead in the energy-saving game. Laptops use about 15-60 watts, while desktops use 65-250 watts — plus another 15-80 watts for a monitor.
He also adds that you can further conserve energy by using an LCD monitor and ditching the high-end video card unless it’s absolutely necessary. Also, turn off printers and other peripherals when they are not in use.
To kill “vampire power,” TreeHugger.com suggests purchasing a power strip. With all peripherals connected to one source, it’s easy to simply flip the switch on power hogs any time.

Establish a backup process
In addition to Peters’ great advice about conserving energy, I discovered the hard way that it also pays to save backup versions of your work. Invest in an external hard drive to hold your digital music library, special photos, and other key documents. Frequent backups ensure that your data doesn’t die with your laptop.
While you are in the process of backing things up, create an emergency file (on good old-fashioned paper) that contains your computer’s serial number along with other key data such as your credit card numbers and phone numbers to reach each company, along with contact info to your insurance company. Access to that information is vital, particularly in the event of an accident, fire, computer theft, or other catastrophe.
Peters warns that those key pieces of information are not safe on your computer. If you are like me and absolutely need a digital holding space for those nuggets of information, he suggests sites like Last Pass as your online vault.
Happy computing! Morieka

Now Let me append hereunder certain contrary reports on discharging the laptop battery regularly as well as other stuffs upon Notebook batteries, gathered from the net : -

Notebook batteries are a common topic of discussion, and the vast majority of questions about them deal with prolonging their lives. There is a lot of information about Lithium Ion (hereafter Li-Ion) batteries to wade through. There are a lot of misconceptions floating around as well. This simple guide addresses the most common notebook battery questions and concerns.

How long will my battery last?
Your notebook battery will deteriorate over time whether you use it or not. Although the Li-Ion industry does not publicize this fact, your battery’s clock began ticking the moment it was assembled. The elements inside your battery slowly react with each other, eventually rendering the battery unable to supply the required power to your notebook. In addition, your battery is rated to last between 300 and 800 charge/recharge cycles. It will gradually lose charge capacity rather than abruptly fail to power your notebook.

The general consensus is that notebook batteries last one to three years. While you can slow the battery’s aging and loss of capacity, you cannot stop either decline. The temperature of the battery, combined with the amount and nature of its usage contribute significantly to your battery’s lifespan. You can ease the aging process with some care and maintenance.TemperatureLower temperatures slow down the self-discharge (loss of charge while disconnected) and aging process of the elements within your battery. Therefore it follows that higher temperatures shorten the life of your battery. Leaving your battery connected while on AC power causes the internal temperature of the battery to rise. Removing your battery and storing it in a cool, dry place will help to slow the aging process. Keeping your notebook in a hot environment is also detrimental to your battery.Amount of UsageThe Lithium-Ion batteries used in notebooks are rated to handle between 300 and 800 charge/discharge cycles. Some of these cycles are used when you leave your battery connected to your notebook while on AC power. On AC power, the notebook will routinely “top-off” the battery when its charge reaches predetermined levels (i.e. 95%). Removing your battery and storing it in a cool, dry place will help to preserve some of these cycles.Nature of UsageLi-Ion batteries do not suffer from the memory-effect (requiring complete discharge before recharging to avoid loss of capacity) like older rechargeable batteries. Regular full discharge/recharge cycles result in an increased loss of capacity per cycle. A series of partial discharge cycles are better for Li-Ion batteries than a single full discharge. You should, however, calibrate your battery routinely.
Connected or Disconnected when on AC Power?Things to consider if:

You are removing the battery while on AC power:
Pros:
• Preserves charge cycles
• Keeps the battery temperature lower thus slowing the aging process
Cons:
• Lose the battery as backup power during power outages and voltage drops
• Unsaved work will be lost and data may be corrupted without backup power
• UPS (uninterruptible power supply) needed to serve as backup power source

You are leaving the battery connected while on AC power:
Pros:
• Battery serves as backup power during power outages and voltage drops
• More convenient for “grab-and-go” use
• Battery doesn’t require sufficient warming time (as it would after being stored in the refrigerator)
Cons:
• Loss of charge cycles
• Battery’s temperature is higher on AC power resulting in accelerated aging

Quick Reference: Simple Guidelines
• Heat is your battery’s worst enemy. Avoid keeping your battery in hot places such as your car during the daytime.
• A full discharge puts more strain on your battery than several partial discharges. You do not need to worry about battery memory with Li-Ion batteries. Get into the habit of recharging the battery when it reaches 10-20%.
• Never discharge your battery to 0% – as this can render your battery useless.
• Calibrate your battery’s fuel gauge by doing a full discharge every 30 cycles. Run the battery to the cut-off point in your notebook to keep the battery’s fuel gauge accurate.
• If you will be on AC power for an extended period of time, you can prolong your battery’s lifespan by removing it and putting it into prolonged storage.
• Prolonged storage should be done with a 40% charge-level and in a cool, dry place. Some experts recommend you place the battery in your refrigerator. Use a sealed plastic bag to keep moisture out if you do this.
• Do not freeze your battery.
• Allow a stored battery to warm to room temperature completely before using or recharging it.

Ten Tips to increase your Laptop's Battery Life
Here are 10 simple, but effective tips to get more out of your laptop battery. There’s no rocket science involved. Just simple tricks.


Written by Tris Hussey of TNW.

1. Turn off WiFi and Bluetooth if you don’t need them. Obviously if you’re trying to be online when you’re on battery power you need to keep these on, but if you’re on a flight or someplace where you aren’t going to be online, just turn the WiFi off. Same goes for Bluetooth, if you don’t need it on, turn it off.
2. Turn down your screen brightness. While screens are a lot more efficient than the used to be, you can still squeeze more time out of your battery if the screen isn’t at full power. The trick here is turn down the screen until it’s too dark to use, then bump it up a notch or two. That should give you the right balance of brightness and power saving.
3. If you have a backlit keyboard, turn the light off. Just like the screen, the keyboard light drains the battery pretty quickly.
4. If you’re not using it, quit it. Every app that is running needs a little processor and hard drive time tostayrunning, all those apps add up to more drain. And don’t just quit the apps you can see all the extras like Dropbox or mouse tools or other add ons use power too…if you don’t really need them, just quit them.
5. If your laptop has a “power saving mode” use it. For example on MacBook Pros there is a setting for More Performance (it can tap into the graphics chip) or Better Battery (no graphics chip). Better battery is clearly the choice here.
6. Set your screen to turn off if not used in a couple minutes. I know it seems extreme, but if you can set your screen to turn off if you’re idle for a minute or two…believe it or not it will make a difference.
7. Have your computer go to sleep if idle for five minutes. Yes, I know, it sounds extreme, but still the idea is that if you’re not actively using your machine, then turning the screen off and going to sleep will help you eek out more power.
8. Avoid connecting things to USB ports or the DVD drive. You want to suck your batter dry in a flash? Connect a phone that needs to charge into your machine and watch a movie off the DVD drive at the same time. Those two are huge power draws, especially USB drives and phones that need charging (obviously a charging phone will suck power straight out of your battery). Just try to put off or avoid using them for long.
9. Use a RAM disk. This is a little geeky, but here’s the idea. If you need to work on a document instead of constantly reading and writing to your hard drive, a RAM disk is a temporary disk that is saved all in RAM. Not accessing the drive means less power usage. Back in the day we used to use RAM disks to speed up all sorts of functions on our machines (an old trick was to put your Firefox cache on a RAM disk), but the trick seems to have fallen out of favor. The utility I used on my Mac (and unwisely deleted) doesn’t seem to be available, but OS X Daily has simple instructions for Mac users. For Windows users I haven’t been able to find something that looks reliable (suggestions are welcome).
10. Run your battery down once a month. I know this is controversial. Yes, it was certainly true that older batteries had a “memory effect” problem, but it was thought that new ones didn’t. I guess we were wrong because even Apple recommends draining your battery once a month. In fact, I’m draining my battery as I’m writing this post. Not only that I’ve disregarded all the advice here (well except for using the DVD drive). It’s still taken nearly two hours to run the machine until it’s down to reserve power. The next step is to just let the the machine drop into sleep and run the battery completely down, then charge it back up.

Evolution of the Cellphone

SRA/Ericsson MTA (Mobile Telephone System A) - Year: 1956
.
The 88-pound MTA phone, shown here, is typical in size and weight of early mobile phone systems from the pre-integrated-circuit era. Most were so heavy and power-hungry that they required permanent installation in a car or other vehicle. Very few people owned, used, or even encountered such devices; for example, the service for the model shown here existed in only two Swedish cities and served a mere 125 subscribers from 1956 to 1967... [it was the] first automatic mobile telephone system (it didn't require a human operator to manually connect the user to an outside phone line).

Motorola DynaTAC 8000X- Year: 1983

Though Motorola announced the world's first handheld mobile phone--a prototype of the DynaTAC 8000X you see above--in 1973, it took ten years for the DynaTAC to reach the market... Upon its release in 1983, the DynaTAC 8000X became an instant cultural icon, both as a status symbol for the rich (thanks to the $ 3995 retail price--$ 8657 in 2009 dollars) and as an almost miraculous wonder-phone that a person could use anywhere. With the DynaTAC, the cell phone revolution had finally begun...
Motorola MicroTAC - Year: 1989

After the success of the DynaTAC, Motorola followed up with the much smaller and lighter MicroTAC phone in 1989. The MicroTAC included a novel space-saving idea: Motorola engineers placed part of the phone's hardware in a hinged section that could fold inward or outward as needed, thus reducing the phone's size when it wasn't in use. The flip concept lives on in many cell phones today...
Motorola StarTAC - Year: 1996

In 1996, Motorola further shrank its line of pocket cell phones, producing the 3.1-ounce StarTAC--which immediately proved popular and influential. The StarTAC expanded on the partially collapsible design of its precursor, the MicroTAC, by allowing users to fold the phone in half when they weren't talking on it. We now call this design "clamshell," for its resemblance to the way a clam opens and closes. The StarTAC's general design was widely imitated, and a large percentage of mobile phones still use it today...
RIM BlackBerry 5810 - Year: 2002

The BlackBerry brand began in 1999 as a simple two-way pager, but it morphed into a line of full-fledged smartphones in 2002 with the BlackBerry 5810, the first of the series to include integrated cell phone support. Thanks to top-of-the-line mobile e-mail and text messaging (the QWERTY keyboard didn't hurt either), BlackBerry phones soon became indispensable tools for businesspeople and other professionals... [it was the first] BlackBerry with an integrated voice cell phone [and] push e-mail support...


Sanyo SCP-5300 - Year: 2002

In 2002, Sprint and Sanyo released the first American cell phone with a built-in camera, the SCP-5300--and the public went crazy for it.

The camera phone became a bona fide cultural phenomenon, allowing the average Joe to quickly and personally share both mundane and earthshaking events with the rest of the world. Today, camera phones are so common that we don't call them "camera phones" anymore...
