Trick to earn free mobile recharge for lifetime


Just today i came across a website which is also providing free online recharge. When i registered on that site, the first thought came was it is similar to Amulyam which is also a mobile recharge website and i have recharged my mobile so many times and still recharging. One more site is ultoo which is again a similar site.

Now my idea is why would i waste my money on recharge when this many websites are available where i can recharge for free. if i recharge 10 from amulyam and 10 from ultoo and 10 from this new site, you will get 30 INR of free recharge. And if you search on Google you will find many more so just think why you would waste money in recharge instead you register and complete some small surveys or play games and earn some recharge for free. happy recharging :)

Register on this new site --> Click here to register for free recharge

Register on Amulyam --> Click here

Top 10 Cell phones Safety facts for everyone

Top 10 Cell phones Safety facts:

1. Keep the handset if possible at least 2 to 7 inches away from your head or use loudspeaker mode. It decreases the transmission of electro- magnetic radiation to the brain significantly.

2. Do not keep the cell phones close to your head when sleeping. Switch it off in the night or keep it 1.80 meters or 6 feet away from your head.

3. If keeping cell phones in pocket keep the keypad towards you so that antenna faces away from you.

4. Don’t use cell phones if pregnant. The developing organs of the fetus or child are the most sensitive to any possible effects of electromagnetic radiation (EMR) exposure.

5. Avoid cell phones usage in ‘metal containers’ like Vehicles, Elevators, Airplanes, Trains and any other type of metal container as it increases the EMR.

6. Avoid using the wired headsets. If you do use headsets use an air tube headset with ferrite beads. Blue tooth are better as they emit 1/100th the EMR of a normal cell phone. With regular headsets you get 3 times more EMR than if you hold the cell phone against your ear.

7. Cell phones are a big NO for Children under 15 years as currently brain tumors are the second leading cause of death in children.

8. Keep cell phones well away from newborns. EMR travel through children’s brains much more easily due to thinner skulls and hence increases the risk of cancer.

9. Avoid using cell phones in your pant pocket – as radiation can affect your fertility. Avoid it in breast pocket if you have a pacemaker.

10. When buying a cell phone – look for one with a low SAR or Specific Absorption Rate. Lower the SAR number the better. For example - Popular Motorola Razr V3x has a SAR of 0.14 – which is amongst the lowest seen recently.

high level workflow for secure password reset


When user asks to reset their password, make them enter their email address Don't indicate if that email address was valid or not (just tell them that an email was dispatched).

This is open for debate as it lowers usability (i.e. I have no idea which email I registered with) but it offers less information to people trying to gather information on which emails are actually registered on your site.

Generate a token (maybe hash a timestamp with a salt) and store it into the database in the user's record.

Send an email to the user along with a link to your http*s* reset page (token and email address in the url).

Use the token and email address to validate the user. Let them choose a new password, replacing the old one. Additionally, it's a good idea to expire those tokens after a certain time frame, usually 24 hours.

Optionally, record how many "forgot" attempts have happened, and perhaps implement more complex functionality if people are requesting a ton of emails.

Optionally, record (in a separate table) the IP address of the individual requesting the reset. Increment a count from that IP. If it ever reaches more than, say, 10... Ignore their future requests.

To give you a little more detail into hashing...

When you hash a value like a password using the md5() function in PHP, the final value is going to be the same for that password no matter which server you run it on. (So there's one difference we can see right away between hashing and encryption... There's no private/public key involved).

So this is where you'll see people mention a vulnerability to rainbow tables. A very basic explanation of a rainbow table is... You md5() hash a bunch of dictionary words (weak passwords) in order to get their md5() hashed values. Put those in a database table (rainbow table).

Now, if you compromise a web site's database, you can run the users' hashed passwords against your rainbow table to (in essence) "reverse" the hash back to a password. (You're not really "reversing" the hash... But you get the idea).

That's where "salting" your passwords is best practice. This means (again, very basic idea here) that you append a random value to the users' passwords before you hash it. Now, when the rainbow table is run against your database, it's not as easily "reversed" because the md5() hash of "password" is different than "password384746".

10 security enhancement points for computer



10 Fast and Free Security Enhancements PC magazine.

Before you spend a dime on security, there are many precautions you can take that will protect you against the most common threats.

1. Check Windows Update and Office Update regularly have your Office CD ready. Windows Me, 2000, and XP users can configure automatic updates. Click on the Automatic Updates tab in the System control panel and choose the appropriate options.

2. Install a personal firewall. Both SyGate (_www.sygate.com) and Zo
neAlarm (_www.zonelabs.com) offer free versions.

3. Install a free spyware blocker. Our Editors' Choice ("Spyware," April 22) was SpyBot Search & Destroy (_http://security.kolla.de). SpyBot is also paranoid and ruthless in hunting out tracking cookies.

4. Block pop-up spam messages in Windows NT, 2000, or XP by disabling the Windows Messenger service (this is unrelated to the instant messaging program). Open Control Panel | Administrative Tools | Services and you'll see Messenger. Right-click and go to Properties. Set Start-up Type to Disabled and press the Stop button. Bye-bye, spam pop-ups! Any good firewall will also stop them.

5. Use strong passwords and change them periodically. Passwords should have at least seven characters; use letters and numbers and have at least one symbol. A decent example would be f8izKro@l. This will make it much harder for anyone to gain access to your accounts.

6. If you're using Outlook or Outlook Express, use the current version or one with the Outlook Security Update installed. The update and current versions patch numerous vulnerabilities.

7. Buy antivirus software and keep it up to date. If you're not willing to pay, try Grisoft AVG Free Edition (Grisoft Inc., w*w.grisoft.com). And doublecheck your AV with the free, online-only scanners available at w*w.pandasoftware.com/activescan and _http://housecall.trendmicro.com.

8. If you have a wireless network, turn on the security features: Use MAC filtering, turn off SSID broadcast, and even use WEP with the biggest key you can get. For more, check out our wireless section or see the expanded coverage in Your Unwired World in our next issue.

9. Join a respectable e-mail security list, such as the one found at our own Security Supersite at _http://security.ziffdavis.com, so that you learn about emerging threats quickly and can take proper precautions.

10. Be skeptical of things on the Internet. Don't assume that e-mail "From:" a particular person is actually from that person until you have further reason to believe it's that person. Don't assume that an attachment is what it says it is. Don't give out your password to anyone, even if that person claims to be from "support."

Four Tips for Longer PC Life



1. Keep your PC in a smoke-free environment. Tobacco smoke can damage delicate contacts and circuits.

2. Leave your PC running. Powering up from a cold state is one of the most stressful things you can do to your system's components.
If you don't want to leave your PC running all the time, use Windows' Power Management settings to put your machine into hibernation rather than completely shutting down.

In Windows XP, right-click the desktop and select Properties. Click the Screen Saver tab and select the Power button. Choose the Hibernate tab to ensure that hibernation is enabled, and then select a time beneath "System hibernates" under the Power Schemes tab.

(Note that this option is not available on all PCs.)
Computers running older versions of Windows may or may not provide similar power-management features. Look under the Power Management icon (Power Options in Windows 2000) in Control Panel to evaluate your machine's capabilities.

3. Don't leave your monitor running. The best way to extend your display's life is to shut it off when it's not in use.

4. Avoid jostling the PC. Whenever you move your system, even if it's just across the desktop, make sure the machine is shut down and unplugged.

1 to 25 ways to speed windows not only defragment

Since defragging the disk won't do much to improve Windows XP performance, here are 25 suggestions that will.

Each can enhance the performance and reliability of your customers' PCs. Best of all, most of them will cost you nothing.

1.) To decrease a system's boot time and increase system performance, use the money you save by not buying defragmentation software -- the built-in Windows defragmenter works just fine -- and instead equip the computer with an Ultra-133 or Serial ATA hard drive with 8-MB cache buffer.

2.) If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.

3.) Ensure that Windows XP is utilizing the NTFS file system. If you're not sure, here's how to check: First, double-click the My Computer icon, right-click on the C: Drive, then select Properties. Next, examine the File System type; if it says FAT32, then back-up any important data. Next, click Start, click Run, type CMD, and then click OK. At the prompt, type CONVERT C: /FS:NTFS and press the Enter key. This process may take a while; it's important that the computer be uninterrupted and virus-free.

The file system used by the bootable drive will be either FAT32 or NTFS. I highly recommend NTFS for its superior security, reliability, and efficiency with larger disk drives.

4.) Disable file indexing. The indexing service extracts information from documents and other files on the hard drive and creates a "searchable keyword index." As you can imagine, this process can be quite taxing on any system.

The idea is that the user can search for a word, phrase, or property inside a document, should they have hundreds or thousands of documents and not know the file name of the document they want. Windows XP's built-in search functionality can still perform these kinds of searches without the Indexing service. It just takes longer. The OS has to open each file at the time of the request to help find what the user is looking for.

Most people never need this feature of search. Those who do are typically in a large corporate environment where thousands of documents are located on at least one server. But if you're a typical system builder, most of your clients are small and medium businesses. And if your clients have no need for this search feature, I recommend disabling it.

Here's how: First, double-click the My Computer icon. Next, right-click on the C: Drive, then select Properties. Uncheck "Allow Indexing Service to index this disk for fast file searching." Next, apply changes to "C: subfolders and files," and click OK. If a warning or error message appears (such as "Access is denied"), click the Ignore All button.

5.) Update the PC's video and motherboard chipset drivers. Also, update and configure the BIOS. For more information on how to configure your BIOS properly, see this article on my site.

6.) Empty the Windows Prefetch folder every three months or so. Windows XP can "prefetch" portions of data and applications that are used frequently. This makes processes appear to load faster when called upon by the user. That's fine. But over time, the prefetch folder may become overloaded with references to files and applications no longer in use. When that happens, Windows XP is wasting time, and slowing system performance, by pre-loading them. Nothing critical is in this folder, and the entire contents are safe to delete.

7.) Once a month, run a disk cleanup. Here's how: Double-click the My Computer icon. Then right-click on the C: drive and select Properties. Click the Disk Cleanup button -- it's just to the right of the Capacity pie graph -- and delete all temporary files.

8.) In your Device Manager, double-click on the IDE ATA/ATAPI Controllers device, and ensure that DMA is enabled for each drive you have connected to the Primary and Secondary controller. Do this by double-clicking on Primary IDE Channel. Then click the Advanced Settings tab. Ensure the Transfer Mode is set to "DMA if available" for both Device 0 and Device 1. Then repeat this process with the Secondary IDE Channel.

9.) Upgrade the cabling. As hard-drive technology improves, the cabling requirements to achieve these performance boosts have become more stringent. Be sure to use 80-wire Ultra-133 cables on all of your IDE devices with the connectors properly assigned to the matching Master/Slave/Motherboard sockets.

A single device must be at the end of the cable; connecting a single drive to the middle connector on a ribbon cable will cause signaling problems. With Ultra DMA hard drives, these signaling problems will prevent the drive from performing at its maximum potential. Also, because these cables inherently support "cable select," the location of each drive on the cable is important. For these reasons, the cable is designed so drive positioning is explicitly clear.

10.) Remove all spyware from the computer. Use free programs such as AdAware by Lavasoft or SpyBot Search & Destroy. Once these programs are installed, be sure to check for and download any updates before starting your search. Anything either program finds can be safely removed. Any free software that requires spyware to run will no longer function once the spyware portion has been removed; if your customer really wants the program even though it contains spyware, simply reinstall it. For more information on removing Spyware visit this Web Pro News page.

11.) Remove any unnecessary programs and/or items from Windows Startup routine using the MSCONFIG utility. Here's how: First, click Start, click Run, type MSCONFIG, and click OK. Click the StartUp tab, then uncheck any items you don't want to start when Windows starts. Unsure what some items are? Visit the WinTasks Process Library. It contains known system processes, applications, as well as spyware references and explanations. Or quickly identify them by searching for the filenames using Google or another Web search engine.

12.) Remove any unnecessary or unused programs from the Add/Remove Programs section of the Control Panel.

13.) Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations. Windows XP offers many different settings in this area. Here's how to do it: First click on the System icon in the Control Panel. Next, click on the Advanced tab. Select the Settings button located under Performance. Feel free to play around with the options offered here, as nothing you can change will alter the reliability of the computer -- only its responsiveness.

14.) If your customer is an advanced user who is comfortable editing their registry, try some of the performance registry tweaks offered at Tweak XP.

15.) Visit Microsoft's Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.

16.) Update the customer's anti-virus software on a weekly, even daily, basis. Make sure they have only one anti-virus software package installed. Mixing anti-virus software is a sure way to spell disaster for performance and reliability.

17.) Make sure the customer has fewer than 500 type fonts installed on their computer. The more fonts they have, the slower the system will become. While Windows XP handles fonts much more efficiently than did the previous versions of Windows, too many fonts -- that is, anything over 500 -- will noticeably tax the system.

18.) Do not partition the hard drive. Windows XP's NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operating system. The same excuses people offer for using partitions apply to using a folder instead. For example, instead of putting all your data on the D: drive, put it in a folder called "D drive." You'll achieve the same organizational benefits that a separate partition offers, but without the degradation in system performance.

Also, your free space won't be limited by the size of the partition; instead, it will be limited by the size of the entire hard drive. This means you won't need to resize any partitions, ever. That task can be time-consuming and also can result in lost data.

19.) Check the system's RAM to ensure it is operating properly. I recommend using a free program called MemTest86. The download will make a bootable CD or diskette (your choice), which will run 10 extensive tests on the PC's memory automatically after you boot to the disk you created. Allow all tests to run until at least three passes of the 10 tests are completed. If the program encounters any errors, turn off and unplug the computer, remove a stick of memory (assuming you have more than one), and run the test again. Remember, bad memory cannot be repaired, but only replaced.

20.) If the PC has a CD or DVD recorder, check the drive manufacturer's Web site for updated firmware. In some cases you'll be able to upgrade the recorder to a faster speed. Best of all, it's free.

21.) Disable unnecessary services. Windows XP loads a lot of services that your customer most likely does not need. To determine which services you can disable for your client, visit the Black Viper site for Windows XP configurations.

22.) If you're sick of a single Windows Explorer window crashing and then taking the rest of your OS down with it, then follow this tip: open My Computer, click on Tools, then Folder Options. Now click on the View tab. Scroll down to "Launch folder windows in a separate process," and enable this option. You'll have to reboot your machine for this option to take effect.

23.) At least once a year, open the computer's cases and blow out all the dust and debris. While you're in there, check that all the fans are turning properly. Also inspect the motherboard capacitors for bulging or leaks. For more information on this leaking-capacitor phenomena, you can read numerous articles on my site.

24.) Key things to save your computer : Defragment, DiskCheck, Error Cleaning, Antivirus, Memory Scanning etc.

25.) Scan every external disk you connect. There are many autorun viruses which may bipass antivirus if not scanned.

7 Dangerous acts after a meal in day to day life

1. Don’t smoke —- Experiments from experts proves that smoking a cigarette after meal is comparable to smoking 10 cigarettes (chances of cancer is higher)

2. Don’t eat fruits immediately — Immediately eating fruits after meals will cause stomach to be bloated with air. Thre fore take fruits 1 -2 hours after meal or 1 hour before meal.

3. Don’t drink tea—— Because tea leaves contain a high content of acid. This substance will cause the protein content in the food we consume to be hundred thus difficult to digest.

4. Don’t loosen your belt———- Loosening the belt after meal will easily cause the intestine to be twisted and blocked.

5. Don’t bathe———- ——- Bathing after meal will cause the increase of blood flow to the hands, legs and body thus the amount of blood around the stomach will therefore decrease, this will weaken the digestive system in our stomach.

6. Don’t walk about———- — People always say that after a meal walk a hundred steps and you will live till 99. In actual fact this is not true. Walking will cause the digestive system to be unable to absorb the nutrition from the food we intake.

7. Don’t sleep immediately—- ——– The food we intake will not be to digest properly. Thus will lead to gastric and infection in our intestine.

Please Share it to your friends let them be aware.
