Optimize Virtual Memory of your computer


What is Virtual Memory?

Virtual memory combines your computer’s RAM with temporary space on your hard disk. When RAM runs low, virtual memory moves data from RAM to a space called a paging file. Moving data to and from the paging file frees up RAM to complete its work.
The more RAM your computer has, the faster your programs will generally run. If a lack of RAM is slowing your computer, you might be tempted to increase virtual memory to compensate. However, your computer can read data from RAM much more quickly than from a hard disk, so adding RAM is a better solution.
If your computer lacks the random access memory (RAM) needed to run a program or operation, Windows uses virtual memory to compensate.

Virtual memory and error messages


If you receive error messages that warn of low virtual memory, you need to either add more RAM or increase the size of your paging file so that you can run the programs on your computer. Windows usually manages the size automatically, but you can manually change the size of virtual memory if the default size is not enough for your needs.

Change the size of virtual memory


If you receive warnings that your virtual memory is low, you'll need to increase the minimum size of your paging file. Windows sets the initial minimum size of the paging file at the amount of random access memory (RAM) installed on your computer plus 300 megabytes (MB), and the maximum size at 3 times the amount of RAM installed on your computer. If you see warnings at these recommended levels, then increase the minimum and maximum sizes.

To optimize the virtul memory follow these steps:

1. Open System by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking System.

2. In the left pane, click Advanced system settings.   If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

3. On the Advanced tab, under Performance, click Settings.

4. Click the Advanced tab, and then, under Virtual memory, click Change.

5. Clear the Automatically manage paging file size for all drives check box.

6. Under Drive [Volume Label], click the drive that contains the paging file you want to change.

7. Click Custom size, type a new size in megabytes in the Initial size (MB) or Maximum size (MB) box, click Set, and then click OK.

8. Increases in size usually don't require a restart, but if you decrease the size, you'll need to restart your computer for the changes to take effect. We recommend that you don't disable or delete the paging file.

Store your Passwords using KeePassX

KeePassX
KeePassX

At the specific Tutorial will present the way to store your passwords using the KeePassX tool. We will analyze the way to generate a strong password using the same tool combined with some parameters. Also we will see the way to add our own database in the case we using KeePass tool.

KeePassX
KeePass was one of the first password management utilities to use security-enhanced password edit controls. Access to the database is restricted by either a master password or a key file. Both methods may be combined to create a "composite master key". If both methods are used, then both must be present to access the password database.

KeePass also encrypts the database with the AES or Twofish symmetric ciphers. AES is the default option, and Twofish is available in 1.x, but is not available in version 2.x. However a separate plugin provides Twofish as an encryption algorithm. Passwords are protected in memory while KeePass is running.

KeePassX Features:
Password management
Import and export
Auto-type, global hot keys, drag-and-drop
Browser Support
Built-in password generator
Plugins

(Note: For the Purpose of this tutorial we will use Ubuntu as OS and KeePassX tool. You can download KeePassx both for Open Source Os and Windows system from official site.)

Create your own WiFi hotspot with 3G

Create your own WiFi hotspot with 3G
Create your own WiFi hotspot

Create your own WiFi hotspot

Almost all the portable gadgets we use today need to be connected to the internet. Instead of getting an individual internet connection for each of them, you can use one of them to create a personal, mobile Wi-Fi hotspot. All your other Wi-Fi enabled devices will then be able to connect to this hotspot and share the primary internet connection. 

Apart from the practicality angle, there can be many uses for this. Your laptop can have high-speed internet connectivity on the move. Within your own network, you
devices will be able to share data with each other. And you'll save quite a bit of cash at the end of the month if you share just one unlimited data plan with five other devices. 

Using a Symbian Phone
Using a Symbian Phone 

Using a Symbian Phone 

Symbian Series 60 phones with Wi-Fi were actually the first to get the ability to create a Wi-Fi hotspot, using a free app called JoikuSpot Light. JoikuSpot also supports certain Samsung Symbian Series 60 phones like the Omnia HD i8910 and the Maemo-powered Nokia N900. Well, JoikuSpot is still around (joiku.com) and has been upgraded to include support for Symbian Series 60 5th Edition (touch phones like the Nokia 5800 and 5530 Xpress Music) and the latest Symbian^3 (for phones like the Nokia C6, C7, N8 and E7). With the Light version of JoikuSpot, you cannot name your network and the Wi-Fi hotspot that you create is unsecured, meaning that anyone with a Wi-Fi enabled device will be able to connect to it. 

The Light version is also limited in the sense that it only supports basic internet protocols (not all websites will be accessible using a hotspot created by JoikuSpot Light). Apart from that, there are no restrictions on the Light version, no time limitations and no obligation to upgrade to the paid version. To download the Light version directly to your phone, visit joikuspot.com/light from your phone's web browser. If you prefer to secure your Wi-Fi hotspot so that only you can access it, you can get the paid version for $12.50 from joikushop.com. 

The iPhone 4 (post iOS 4.3)
The iPhone 4 (post iOS 4.3) 

Using iPhone 4 (post iOS 4.3) 

Wi-Fi tethering on the iPhone was previously only available for jailbroken devices. The MyWi application (available for $19.99 from the Cydia installer on jailbroken devices) can connect to a cellular network on the iPhone 2G, 3G, 3GS, 4 and iPad to create a personal Wi-Fi hotspot. The app also enables USB and Bluetoothtethering on the same devices. More information on MyWi can be found on the developers website, intelliborn.com. No such app is available for non-jailbroken devices. However, with the latest iOS 4.3 software update (available to download from March 10, 2011 onwards), the iPhone 4 also gets the personal Wi-Fi hotspot option officially. Using the new feature, three devices can connect to the iPhone 4 using Wi-Fi, and another two using USB and Bluetooth. At this point, it's not clear as to why Apple is not offering the feature on older devices like the iPhone 3G/3GS or for that matter on the 3G version of the iPad. 

Using an Android device
Using an Android device 

Using an Android device 

Android has the most options when it comes to sharing an internet connection via Wi-Fi. For starters, any phone or tablet with Android version 2.2 or later has the personal Wi-Fi hotspot feature built in by default (without any restrictions). To activate it, go to Settings > Wiress and Network > Mobile AP. Once you activate Mobile AP, you can configure it with a name, add an access password and even hide the network so that only trusted devices can connect to it. 

There are many options for older Android devices too. PdaNet is an option for USB and Bluetooth tethering (It was earlier also available for Palm and Windows Mobile phones). You can download the app directly from the Android App Market, connect the device to your computer and access the data connection. Another open source project is Android Wi-Fi Tether (available from code.google.com/p/android-wifi-tether). The app is available even for older devices with Android version 1.1 and 1.5 (cupcake). However, to use the Android Wi-Fi Tether app with Android version 2.1, you need to have a 'rooted' device. Rooting an Android phone is a process similar to jailbreaking on Apple iOS devices. It allows more access to the device's hidden settings. Rooting is not illegal but will definitely void the warranty on the phone. 

Windows Mobile

Using Windows Mobile

Devices like the HTC Touch Diamond and HTC HD2 powered by Windows Mobile 6.5 can also use JoikuSpot-the same application that Symbian smartphones use. It is available for purchase and immediate download from joikushop.com. Another option is WmWiFirouter (wmwifirouter.com). While a 21-day free trial of the app is available, you will have to buy the full version for Rs 940 to continue using it after that. Wi-Fi tethering is not yet available for the latest Windows Phone 7 devices yet.




Using a Windows 7 Laptop
Using a Windows 7 Laptop 

Using a Windows 7 Laptop 

If you have a Wi-Fi enabled Windows 7 laptop (32-bit or 64-bit), a free program called Connectify (connectify.me) can create a personal hotspot, allowing other nearby laptops, phones, portable gaming consoles and tablets to use your internet connection. Like with any Wi-Fi router, you can configure it with a name, add access passwords and hide the network (disable broadcasting). Once the software is installed, the Connectify hotspot can be started and stopped at any time from the Windows 7 notification area on the right side of the taskbar. 

Connectify works with most Wi-Fi cards in laptops, though the functionality may be limited in some cases. For example, if your laptop connects to the internet using Wi-Fi itself, it may not be able to use Connectify to further share the network. If your laptop connects to the internet using an Ethernet cable or using a USB data card, Connectify will work without an issue. However, if your laptop has a Windows 7 certified Wi-Fi card, it will support 'Access Point' connections. This means that even if the laptop connects to the internet using Wi-Fi, it will still be able to share the internet connection with other devices. If your laptop has a Windows 7 certified Wi-Fi card that supports Access Point connections, Connectify can also be used as a 'repeater' or range extender for your home Wi-Fi network. All you have to do is place your laptop towards the periphery of your existing Wi-Fi network and enable Connectify. 
Unfortunately, Connectify depends on improvements made to Windows 7 to operate, hence it is not compatible with Windows XP or Vista (although it is compatible with Windows Server 2008 R2). Connectify will also soon be available for Android devices (available on the Android App Market). 

Tata PhotonWi-fi

Using Tata PhotonWi-fi 

Apart from the regular Tata Photon+ USB device, you can also go for the Tata Photon Wifi. It is a pocket-sized, battery-powered router that connects to the Photon network and provides high speed Wi-Fi connectivity for up to 5 nearby devices. It costs Rs 6,599 (plus the usual monthly plan).





Olive VR-9 Router
Olive VR-9 Router 

Using Olive VR-9 Router 

This battery-powered device is an easy way out if you already have a high-speed USB data card. The Olive Nexus VR-9 has a USB port into which you can plug in a data card and it creates a Wi-Fi hotspot that can be accessed by five devices. It costs Rs 3,500 and can be purchased from olivetelecom.in. It has a complicated initial setup process-you have to connect the device with an Ethernet cable, enter the router's IP address and feed in data card details (number, username, password). The battery lasts for 4 hours but you have the flexibility to plug your data card directly into the laptop anyway. It might make more sense than the Tata Photon WiFi because even after adding the cost of a USB data card (Rs 1,599 for Reliance, Rs 1,799 for Tata), it is still cheaper.
