First of all introduction how to switch to a dvorak keyboard layout
1, Decide whether the Dvorak keyboard is the right choice for you. Take the time to learn about its advantages and disadvantages:
The standard QWERTY keyboard layout was designed to prevent typewriter jams (which is no longer necessary with computers), whereas the Dvorak layout was designed specifically to be easy on the hands.
Using a Dvorak keyboard may reduce the likelihood of carpal-tunnel syndrome.
If you share your computer with others or if you frequently switch computers, the changed layout will be confusing. However, on Windows XP, for example, each account can be set to a different typing layout--so use your own account with Dvorak if you can so you don't confuse the other(s).
If you already change your keyboard to type in other languages, having an additional layout in the mix will be confusing.
Dvorak allows for higher speeds and accuracy than can be achieved on a QWERTY keyboard, but the ultimate gain in speed must outweigh the temporary sacrifice in speed during the transition.
2, Switch your computer from QWERTY to ANSI Dvorak. This is quite easy to do in most operating systems. Refer to the external links at the end of this article for details catered to your specific operating system.
3, Consider relabeling the keys on your keyboard or buying a Dvorak keyboard. This may be helpful when you're learning, but it's preferable simply to get used to not looking at your hands when you type. You will be able to type on any keyboard with a changed layout, and you will type faster if you never look at your hands.
4, Learn where to put your fingers to touch-type. If you already know how to touch-type on a QWERTY, the same fingers operate the same keys. The keys just produce different letters. The home row is:
Dvorak: AOEU - ID - HTNS
QWERTY: ASDF - GH - JKL;
5, Download free typing software that teaches Dvorak, or take online lessons. Whereas there is a wide array of software support for QWERTY, there are only a few good Dvorak programs, (some are listed in the External Links section). Make sure you go through lessons at a reasonable pace. Although the lessons may be easy, do them multiple times to ensure you have mastered everything they offer.
6, Practice, practice, practice! Try to use Dvorak as much as possible, even if you hate the initial speed reduction and confusion. Practice will make you more familiar with the keyboard layout. Practicing for small amounts of time, such as fifteen minutes per day is more effective than practicing for hours once a week.

Change a Car Battery
1,Make sure the battery needs replacing.
You don't want to spend time and money installing a new battery if the problem is not with the battery itself. Look for sulfate build-up in the form of a whitish or blue residue around the terminal--removing this can sometimes solve issues with a faulty battery. DO NOT TOUCH THIS POWDER WITH YOUR BARE HANDS, as it can often contain dried out sulfuric acid which will begin to unnoticably corrode your skin. Also verify that the battery has been given the chance to recharge properly by driving constantly for 30 minutes. Finally, check the alternator. Some cars also have a battery meter, with the engine running, the alternator usually maintains a charge close to 13.8-14.2 volts in a properly functioning charging system. The battery should have 12.4-12.8 volts with the engine off, and with no accessory load. If you've determined that your battery problems can't be attributed to any of the above, or if you see cracks or oozing liquid on the top of the battery, it's probably safe to proceed with replacement.
2,Buy the correct replacement battery.
Find out what kind of battery you're replacing and bring this information to a local auto parts store. This is important because automotive batteries vary in size, and you will want to purchase a battery which matches the size of the battery tray/support in your vehicle.
In some areas of the US, you will be charged a "core" fee when you purchase a new battery, if you bring in your old battery after or when purchasing your new battery you will not get charged this fee
3,Set up a secure working environment
Park on a flat, level surface at a safe distance from traffic, sparks or open flames. Put on the parking brake. Don't smoke, and make sure any smokers in proximity to the working area know not to smoke as well. Remember that electricity is not the only danger; batteries contain a sulfuric acid electrolyte solution, which is highly corrosive and produces a flammable gas. Put on gloves and safety goggles.
4,Remove the cigarette lighter and plug the memory keeper into the lighter socket.
A memory keeper will keep the PIN codes and settings for radios and navigation systems from getting erased when you disconnect the battery. If you don't have a memory keeper make sure you have all the PINs for your electronic equipment before you start. Use may wish to check your car manual to see what devices may be affected.
5,Open the hood
After opening your hood, use the prop rod to keep your hood open.
6,Locate the battery
The battery should be located in an accessible part on either side of the car's frame. The battery is a rectangular box with two cables attached to it. Some european cars have the battery under the metting in the trunk, or inside the fender of the wheel well.
7,Identify battery terminals
Locate the positive and the negative terminals of the old car battery. The positive terminal will have a plus sign and the negative terminal will have a minus sign.
8,Disconnect the negative terminal - Loosen the negative cable clamp with a wrench and slide it off of the terminal. If the cables are unmarked, label them so that they don't get mixed up. It is also important that you disconnect the negative terminal socket before the positive terminal socket. Otherwise, you may short circuit the positive terminal to a grounded part of the car.
9,Disconnect the positive terminal.
10,Remove the car battery
Unfasten the battery holder and remove any screws, clamps or bars holding the battery in place. Carefully lift the battery out of the car. Remember that a battery can weigh 30 to 60 pounds, or 13.5 to 27 kilos, so if you have any back problems, get a helping hand.
11,Clean the terminal clamps and the battery tray.
You can use a baking soda solution and a wire brush. If there's any severe corrosion, consider replacement by a mechanic. Otherwise, let the area dry before moving onto the next step.
12,Replace the battery
Place the new battery where you just took the old battery out, with the positive and negative terminals on the correct sides. Connect all the screws, clamps or bars that may hold the battery in place.
13,Reconnect the positive terminal
Tighten the clamps using a wrench.
14,Reconnect the negative terminal
Tighten the clamp with the wrench.
15,Apply battery lithium grease
Spray the terminals with lithium grease to prevent corrosion.
16,Close the hood
Shut the hood of your car firmly and start your car. Check that all the electronic devices are working properly.
17,Dispose of the battery at service garages, auto supply stores, and recycling centers. There may be a small fee for the service, but throwing the battery away as normal garbage is not an option.
In the US, most battery retailers charge a deposit on the battery, which will be refunded with the return of an old battery.

How to Clean a Keyboard.
1,Shut down the computer and detach the keyboard connector before any cleaning procedure. Do not remove or connect a keyboard while the computer is running. Doing so may damage the machine, especially a non-USB based keyboard.
2,For a quick cleaning, turn the keyboard upside down and use a can of compressed air to blow out any foreign matter. Be sure to do this in a location where falling debris can be cleaned up easily. Turn the keyboard upside down and tap on it a few times. You should see a bit of dirt fall out. Change the angle and tap harder to make most of it get out.
3,Clean the sides of the keys with a cotton swab dipped in isopropyl alcohol.
4,For a more thorough cleaning, remove all of the keys. Do this by gently prying up each key with a small screwdriver or a similar lever. When the keys have been removed, blow out any debris with compressed air. With a moist (but not wet) cloth, lightly swab all surfaces. Do not allow any type of fluid to enter the keyboard.
5,Clean the individual keys and place them back in the keyboard.

Since early transistors were not available with sufficient voltage and current ratings for most inverter applications, it was the 1957 introduction of the thyristor or silicon-controlled rectifier that initiated the transition to solid state inverter circuits.
12-pulse line-commutated inverter circuitThe commutation requirements of SCRs are a key consideration in SCR circuit designs. SCRs do not turn off or commutate automatically when the gate control signal is shut off. They only turn off when the forward current is reduced to zero through some external process. For SCRs connected to an AC power source, commutation occurs naturally every time the polarity of the source voltage reverses. SCRs connected to a DC power source usually require a means of forced commutation that forces the current to zero when commutation is required. The least complicated SCR circuits employ natural commutation rather than forced commutation. With the addition of forced commutation circuits, SCRs have been used in the types of inverter circuits described above.
In applications where inverters transfer power from a DC power source to an AC power source, it is possible to use AC-to-DC controlled rectifier circuits operating in the inversion mode. In the inversion mode, a controlled rectifier circuit operates as a line commutated inverter. This type of operation can be used in HVDC power transmission systems and in regenerative braking operation of motor control systems.
Another type of SCR inverter circuit is the current source input inverter. A CSI inverter is the dual of a six-step voltage source inverter. With a current source inverter, the DC power supply is configured as a current source rather than a voltage source. The inverter SCRs are switched in a six-step sequence to direct the current to a three-phase AC load as a stepped current waveform. CSI inverter commutation methods include load commutation and parallel capacitor commutation. With both methods, the input current regulation assists the commutation. With load commutation, the load is a synchronous motor operated at a leading power factor.
As they have become available in higher voltage and current ratings, semiconductors such as transistors that can be turned off by means of control signals have become the preferred switching components for use in inverter circuits.

Prolong the Life of Your Battery
1,Initialize a new battery. New batteries should be fully charged before their first use to obtain maximum capacity. Nickel-based batteries should be charged for 16 hours initially and run through 2-4 full charge/full discharge cycles, while lithium ion batteries should be charged for about 5-6 hours. Ignore the phone telling you that the battery is full--this is normal but is not accurate if the battery is not initialized. #DO NOT fully discharge a lithium-ion battery! Unlike Ni-Cd batteries, lithium-ion batteries' life is shortened every time you fully discharge them. Instead, charge them when the battery meter shows one bar left. Lithium-ion batteries, like most rechargable batteries have a set amount of chargers in them.
2,Keep the battery cool. Your battery will last longest if used near room temperature, and nothing wears on a battery like extended exposure to high temperatures. While you can’t control the weather, you can avoid leaving your phone in a hot car or in direct sunlight, and you don’t have to carry your phone in your pocket, where your body heat will raise its temperature. In addition, check the battery while it’s charging. If it seems excessively hot, your charger may be malfunctioning.
3,Charge your battery correctly, in accordance with its type. Most newer cell phones have lithium-ion batteries, while older ones generally have nickel-based batteries. Read the label on the back of the battery or in the technical specifications in the manual to determine which yours is.
a) Nickel-based batteries DO NOT generally suffer from a misunderstood phenomenon known as the "memory effect." As described in Wikipedia and many expert sources,the term "memory effect" has been widely mythologized to describe any and all deterioration of NiCd, in many cases misleading consumers into further shortening the lives of the batteries through overdischarging to "recondition" them.
b) This section formerly read: If you charge the battery partially enough times, eventually the battery "forgets" that it can charge fully. A nickel-based battery suffering from memory effect can be reconditioned, which requires the battery to be completely discharged, then completely recharged. The appropriate length of time between reconditionings varies. A good rule to follow for nickel-battery cell-phones is to discharge them completely once every two to three weeks, and only when you have a charger available.
c) Lithium ion batteries can be preserved by careful charging and avoiding storing them at full charge.[5] They do not require "reconditioning."
d) Regardless of the battery type, use only a charger rated for your battery, and discontinue use of a charger that causes the battery to heat up excessively.
4,Store batteries properly. If your battery will be out of use for a while, disconnect it from the phone and store it in a cool place (the refrigerator is good, but freezing temperatures do not slow oxidation) and away from metal objects. Ensure that the battery is not exposed to moisture; try putting the battery in an airtight container or bag. Lithium ion batteries are not rated to operate at refrigerated temperatures, so let the battery sit outside the refrigerator for at least an hour before using it again. Lithium ion batteries oxidize least when they are stored at 40% charge. Never store a lithium battery at low voltage. Recharge batteries after storage.
5,Clean the battery contacts on the battery and on the phone. Over time, contacts may accumulate dirt. Clean them with a cotton swab and rubbing alcohol to maximize the efficiency of energy transfer. In addition, if the contacts are two different metals, such as gold and tin, accelerated corrosion known as "fretting" occurs. Cutting the corrosion from fretted contacts often requires solvents, such as acetone or nail polish remover. Be careful: these solvent dissolve plastic, so use a Q-Tip to avoid damaging the battery housing or the phone.

Increase time between charges make mobile phone battery last longer
Increase time between charges make your mobile phone battery last longer
1,Turn the phone off.
This is probably the most effective and most simple way of conserving your battery’s power. If you don't plan on answering the phone while you're sleeping or after business hours, just turn it off. Do the same if you are in an area with no reception or in a roaming area, since constantly searching for service depletes the battery fairly quickly. Some phones have an automatic power save feature, but it takes about 30 minutes with no service to kick in. By then, much battery power has been used.
2,Stop searching for a signal.
When you are in an area with poor or no signal, your phone will constantly look for a better connection, and will use up all your power doing so. This is easily understood if you have ever forgotten to turn off your phone on a flight. The best way to ensure longer battery life is to make sure you have a great signal where you use your phone. If you don't have a perfect signal, get a cell phone repeater which will amplify the signal to provide near perfect reception anywhere.
3,Switch off the vibrate function on your phone, and use just the ring tone instead. The vibrate function uses up a lot of battery power. Keep the ring tone volume as low as possible.
4,Turn off your phone's back light when not in use.Turn off your phone's back light. The back light is what makes the phone easier to read in bright light or outside. However, the light also uses battery power. If you can get by without it, your battery will last longer. If you have to use the back light, many phones will let you set the amount of time to leave the back light on. Shorten that amount of time. Usually, one or two seconds will be sufficient. Some phones have an ambient light sensor, which can turn off the back light in bright conditions and enable it in darker ones.
5,Avoid using unnecessary features. If you know it will be a while before your phone’s next charge, don’t use the camera or connect to the Internet. Flash photography can drain your battery especially quickly. If your phone has bluetooth capability, disable it when not in use.
6,Keep calls short. This is obvious, but how many times have you heard someone on their mobile phone say, "I think my battery’s dying," and then continue their conversation for several minutes? Sometimes, the dying battery is just an excuse to get off the phone, but if you really need to conserve the battery, limit your talk time.
7,Turn off Bluetooth. BT will drain your battery very quickly, and having it on can cause you problems near virus-infected smartphones.
8,Same goes for WIFI and GPS if your phone has these features built in. Keep them off, save more power.
9,Use GSM - Using your phone in 3G / Dual Mode will drain the battery quicker than if you just use GSM mode - have a look at your phones spec and you'll see it will quote two different battery life times - normally 50% more for pure GSM use.

Key types of navigation and typing mode.
Navigation keys include a variety of keys which move the cursor to different positions on the screen. Arrow keys are programmed to move the cursor in a specified direction; page scroll keys, such as the 'Page Up and Page Down keys', scroll the page up and down. The Home key is used to return the cursor to the beginning of the line where the cursor is located; the End key puts the cursor at the end of the line. The Tab key advances the cursor to the next tab stop.
The Insert key is mainly used to switch between overtype mode, in which the cursor overwrites any text that is present on and after its current location, and insert mode, where the cursor inserts a character at its current position, forcing all characters past it one position further. The Delete key discards the character ahead of the cursor's position, moving all following characters one position "back" towards the freed place. On many notebook computer keyboards the key labeled Delete serves the same purpose as a Backspace key. The Backspace key deletes the preceding character.
Lock keys lock part of a keyboard, depending on the settings selected. The lock keys are scattered around the keyboard. Most styles of keyboards have three LEDs indicating which locks are enabled, in the upper right corner above the numpad. The lock keys include Scroll lock, Num lock,and Caps lock.
