How to Increase SMS quotas in Gmail
- Initially, you’re granted a quota of fifty messages.
- Every time you send a message, your quota decreases by one.
- Every time you receive an SMS message in Chat (for example when a phone user replies to one of your messages) your quota increases by five, up to a maximum of 50.
Keep in mind that if you’d like a higher message quota, you can always send an SMS to your own phone, and then reply to that message multiple times. Every time you send a reply message, your quota is increased by five. Effectively, you’re buying more messages by paying your phone company for these outgoing messages.

Sending SMS from Gmail
In order to use this feature you have to enable the SMS (text messaging) in Chat lab. You can send Free SMS messages to your contacts’ mobile phones using Gmail Chat. Here’s how to Send Free SMS from Gmail:
01. Enter your contact’s name in the ‘Search or invite friends’ box in Chat, and select Send SMS from the box of options that Enter your contact’s name in the ‘Search or invite friends’ box in Chat, and select Send SMS from the box of options that appears to the right of your contact’s name. Or, if you already have a Chat window open for this contact, just click Options, and select Send SMS.
02. In the dialog box, enter a phone number in the ‘Send SMS messages to this number’ field. For now, this feature works only on United States phone numbers. If you’re outside the US, you can still use it, but you won’t see the SMS option in Chat until you enable it manually in the Chat settings page.
03. Click Save.
04. A Chat window appears. Just type your message as you would normally. When you hit Enter, the message will be sent to the phone number you entered.
If your contact replies, the text message response will appear as a reply in Chat. These conversations are stored in your Chat history just like regular chats (but keep in mind that you can’t go off the record while communicating via SMS).
When replying with an SMS from phone to Gmail, you will be charged a regular SMS rate by your mobile provider. However, sending SMS from the Gmail Chat to a phone is FREE. As of this moment, every user can initially send up to 50 messages continuously. Every reply back from a mobile phone refreshes the counter by five messages, up to a maximum of 50. Even if you go down to zero, however, you will not be locked out of the system. The counter will increase back up to one 24 hours later.

Facebook Launches Subscribe Button
Facebook today is rolling out a key new feature: a one-way follow model called Subscriptions.
Users will be able to decide if they want to see all updates from their friends, most updates, or just important updates, such as a friend announcing an engagement or a new job. It also gives users the option to block posts about games, which should be welcome news to thouse who complain about Facebook spam.
The subscribe function also incorporates even more features that seem to be influenced by Google’s new social network,that it was making it simpler to put friends into groups. Now, as on Google+ or on Twitter, users can follow other’s profiles without needing to become friends with them. Anyone who enables the Subscribe button will give others the option to view tweets they’ve marked as “Public.”
Facebook says the feature will appeal to anyone looking to reach a broader audience, like journalists, artists, and political figures. To start sharing your own posts publicly, head to the new tab beneath your profile photo that says Subscriptions. Click it, and you’ll have the option to broadcast your public updates to anyone who has subscribed to you. Note that you’ll only syndicate updates that are marked Public; updates shared with Friend Lists won’t be seen by your subscribers.

Windows 7 security
01. AppLocker
It Specify what software is allowed to run on a user’s PCs through centrally managed but flexible Group Policies. AppLocker is very similar to Software Restriction Policies (SRP). In fact, you may ask yourselves what the difference is. Well, AppLocker has a friendlier user interface, the ability to set restrictions based on application version number or publisher, and is easier to work with for less knowledgeable users.
Now, if you’re still wondering what AppLocker is, it’s a tool that allows you to restrict the execution of programs, installers and scripts on a machine with Windows 7 installed. Rather than using third-party security tools, Windows 7 has a built-in mechanism that allows tight, per-application execution control. The tool can be used to allow or deny certain programs or files to run, which can be used to make your system very secure against damage, accidents, misuse, or attacks.
Accessing AppLocker is not straightforward, which is why I’ve kept this software for the second article. You will need to invoke the Group Policy Editor, by running:
cmd > gpedit.msc
This is no different than Group Policies on Windows XP. and also it explains how to use Software Restriction Policies. AppLocker is a natural extension of this strategy, so if you’ve used the former, you’ll be instantly very comfortable with the new feature in Windows 7.
AppLocker can be found in the Computer Configuration tree, under Security Settings, Application Control Policies.
Your first step would be to configure rule enforcement. You can either have the rules in place or just audit for changes in the system without actually preventing or allowing them.
Then, you should create rules. In the right pane, right-click anywhere. Beginners or less experienced users should start with auto-generated rules. Manual rules can be created later, if needed.
Creating rules is very simple. You just follow a wizard. You create rules based on software groups. For example, you can have a rule for Program Files, a rule for Windows directory, a rule for Users directories, etc.
You can decide how to catalog your files, by digital signature (publisher), hash or path. It is recommended not to use path rules for Users directories, because the location of files can easily change, circumventing your security.
Once your directories are scanned, you’ll get the list of rules. You will be able to review the list and individually remove select items, if needed.
Once this is done, you will be asked to create a default set of rules. If you’re not really sure how AppLocker works, you should do this, to prevent potentially crippling the functionality of your system.
And this is what the Group Policy Editor shows now:
Manual rules
As said before, you can also fine-tune your security and create manual rules. Again, right-click and choose Create New Rule. In my case, I will create some rules for downloaded installed files that sit in the Downloads folder. These will include benign items like CuteWriter, Foxit Reader and IrfanView, just for the sake of the demonstration.
Working with AppLocker is not easy, but it’s definitely worth the investment. Combined with the proper use of the firewall and User Account Control (UAC), you can make your operating system well secured without bleeding the resources one bit.
BitLocker is an encryption software, which lets you encrypt your drive and your files, thus preventing the compromise of data integrity in case your computers get stolen. A similar feature did exist in Windows XP, but it is now easier to use and implement.
You can find BitLocker in the Control Panel:
I will merely inform you that this option exists and that you should explore it, if you like. That said, I do not recommend it, and here’s why:
Proprietary format
Encryption should never be closed-source. Always use open-source, proven, well tested solutions, like TrueCrypt, which offers the same capabilities, and then some, including cross-platform compatibility.
Hardware requirements
BitLocker has some rather curious requirements. One is that you have installed Windows 7 on a computer that supports Trusted Platform Module (TPM), which allows BitLocker to store its keys in a special microchip. Failing that, you will need an external USB key on to which you will store the encryption keys.
Moreover, BitLocker requires that you have at least two partitions on the system, both formatted with NTFS.
Personally, I find the requirements to be too much, especially considering the fact free, open-source alternatives like PGP and TrueCrypt require no such thing. Furthermore, both these solutions are proven workhorses of the encryption world, whereas BitLocker is a closed-source tool that you cannot use with other operating systems.
While encryption can potentially add to your security, which is why it’s listed as an item in this article, BitLocker itself does not have merits that warrant using. In this particular case, knowing which security features not to use is the part of the overall security scheme that I’m trying to teach.
03. Parental Control
In Windows 7 you can set limits on your kids’ computer use—and help them be safer online—without constantly peeking over their shoulders.
Parental Controls helps you limit how much computer time children have, as well as which programs and games they can use (and perhaps more importantly, when). With the Parental Controls in Windows Media Center, you can also block access to objectionable TV shows and movies.
To help keep your children safer online, download Windows Live Family Safety. This free program helps you manage which websites your children see and who they can talk to online. It also provides helpful, easy-to-read reports of their online activity.
What can I control with Parental Controls?
- Set specific time limits on your children’s computer use. You can set time limits to control when children are allowed to log on to the computer. Time limits prevent children from logging on during specified hours. You can set different logon hours for every day of the week. If they’re logged on when their allotted time ends, they’ll be automatically logged off.Prevent your children from playing games you don’t want them to play. Control access to games, choose an age-rating level, choose the types of content you want to block, and decide whether you want to allow or block specific games.Keep your children from running specific programs. Prevent children from running programs that you don’t want them to run.
To turn on parental control you should have standard user rights.
Open Parental Controls by clicking the Start button , clicking Control Panel, and then, under User Accounts and Family Safety, clicking Set up parental controls for any user. If you’re prompted for an administrator password or confirmation, type the password or provide confirmation.
