I was just browsing through the net and found this amazing piece of information about Facebook. The statistics here shows how we have got addicted to Facebook. Although it seems to have impressed people a lot, there are limitations of Facebook too. Users needs to be careful and senseful while using Facebook. However, Facebook is always fun!

Here is an image which shows how we are linked with Facebook....

Did you know the Gmail Chat client has Group Chat built into it?  That’s right, using the Gmail web chat client you can spin up a group chat session and chat with multiple people at the same time in just a matter of seconds.  For me, this feature was entirely overlooked.  Sure, I saw the phone and the camera button, but I completely missed the Group Chat button until MrGroove pointed it out a few days ago when we had a groovyPost team chat.

So, if your the chairman of your companies Party Planning Committee, read on to see how you can spin up a groovy Group Chat session the next time you planning something in the office!

To start using group chat in Gmail, just Click the Add people icon near the top of the chat box.  The screenshot below is a view of Gmail chat in a pop-out window. You can add as many contacts as you’d like to the chat, which makes this a groovy way to text-conference.

Once you’ve added the person, they’ll show up in the chat and will be able to hear any messages you send.  Note that you’ll be knocked out of off the record chat once your 3rd party enters.

This feature works in the normal gmail window as well, as shown in the screenshot below.

Gmail group chat is an often unused and overlooked feature from Google’s email service.  Thanks to learning about this feature, I can now spam multiple people from a single window.  It’s a win for everyone!!!!

Thanks to Groovypost.

According to Hurricane Electric an Internet Service Provider, the Internet will run out of its IPv4 version of IP addresses on 2nd February at around 4am. This is only a predicted time based on a rate of IP addresses assigned every hour.

 

The ISP has also launched a countdown accounts termed as “IPcalypse” on Facebook & Twitter.
IPv4 version of IP addresses supports only 4 billion Unique addresses, which is not enough for Internet as the number of devices are increasing at a rate of over 1 million per hour.

This problem can be solved by using IPv6 version which has 340,282,366,920,938,463,463,374,607,431,768,211,456 (You can call this a Zillion) Unique IP addresses.
Both IPv4 & IPv6 can co-exist despite being largely incompatible. Software and hardware developers are working on transition mechanisms, and most operating systems now install support for IPv6 by default. The IPcalypse campaign by Hurrican Electric is also encouraging other ISPs to change to IPv6.

Generally Computers often get slow because of temporary memory which gets stored in our PC, So we need to Repair the Registry To Speed Up A Computer. A lot can go wrong with computers over time. With regular use, computers can not only develop bad sectors and disk errors, they can also develop registry errors which can render your computer useless. To counter such threats, what you need is regular registry repair, which can assure that the heart of your computer stays fit and you keep getting the best from your machine.

What is Registry?

Registry is the heart of all modern operating systems. It’s the fundamental component where all the critical files needed to run the computer and the various software are listed. It contains critical information such as the values of settings for different programs, users, documents types, system hardware and other things. A slight error in registry can throw your computer in a spin and you on the edge of frustration.

Keeping a check on changes made in registry is beyond any human for its frequency and unconventional nomenclature. Files name usually contain strange permutations of numbers and abbreviations which might not make sense to a human brain.

With registry repair, you can catch the errors early and ensure that nothing much goes wrong with how your computer performs.

Unfortunately, there is no inbuilt tool from Microsoft that can help you maintain registry. You need third party tools to scan and repair registry.

A reliable registry repair tool must look for possible errors in registry files and fix them. It should also look for redundant files that consume hard disk and have no role what so ever. A smartly programmed registry repair tool must delete such files and keep the registry as light as possible.

What you can do on your part to keep these errors at the minimum is try to keep the number of application limited to just what you need. Keep deleting and uninstalling things that you don’t require anymore. With such an approach, you can help registry repair tools perform better.

In this post we have checked Repair the Registry To Speed Up A Computer, in our next post we will Check back for more registry repair tips soon!

 

 

This post describes how to connect GPRS from mobile phones via bluetooth in Ubuntu. This procedure is explained for Aircel connection. However, the changes that need to be done for Airtel users are mentioned at the end. Similar procedure works for other network service providers as well.

1. First you need to pair your bluetooth enabled mobile with Ubuntu. You can do that by clicking on the bluetooth icon on the top right of the screen. Or you can find it in System->Preferences. 

2. Then, Open a terminal and type: 

$ sdptool search DUN

You should get this
Code:
Searching for DUN on 00:13:FD:CC:F6:5C ...
Service Name: Dial-Up Networking
Service RecHandle: 0x10005
Service Class ID List:
  "Dialup Networking" (0x1103)
Protocol Descriptor List:
  "L2CAP" (0x0100)
  "RFCOMM" (0x0003)
    Channel: 2
Language Base Attr List:
  code_ISO639: 0x454e
  encoding:    0x6a
  base_offset: 0x100
Profile Descriptor List:
  "Dialup Networking" (0x1103)
    Version: 0x0100

3. Note your phones mac address and channel number which is in red.
In my case phone's mac address is 00:13:FD:CC:F6:5C and channel number is 2

4. Next type this command:
 $ sudo gedit  etc/bluetooth/rfcomm.conf

And add the following

Code:
rfcomm0 {
        bind yes;
        device 00:13:FD:CC:F6:5C;
        channel 2;
        comment "Nokia 3230 via Bluetooth";
}

Enter your phones's mac address and channel number
save and exit.

5. now test the connection by following commands

Code:
$ sudo rfcomm release 0
$ sudo rfcomm connect 0
After a delay you will get the following

Code:
Connected /dev/rfcomm0 to 00:13:FD:CC:F6:5C on channel 2
Press CTRL-C for hangup
Now you have data connection to your phone!.
Press ctrl+C to break connection.

6. Now we have to setup ppp. In my case service provider is Aircel, Type in

Code:
$ sudo gedit /etc/ppp/peers/aircel
And enter the following

Code:
# Aircel PPP initialisation/termination script
noauth
connect "/usr/sbin/chat -v -f /etc/chatscripts/aircel-connect"
disconnect "/usr/sbin/chat -v -f /etc/chatscripts/aircel-disconnect"
silent
debug
/dev/rfcomm0
115200
defaultroute
usepeerdns
Save and exit

7. Now type in

Code:
$ sudo gedit /etc/chatscripts/aircel-connect
Enter the following

Code:
# Aircel PPP CONNECT script
TIMEOUT         5
ECHO            ON
ABORT           '\nBUSY\r'
ABORT           '\nERROR\r'
ABORT           '\nNO ANSWER\r'
ABORT           '\nNO CARRIER\r'
ABORT           '\nNO DIALTONE\r'
ABORT           '\nRINGING\r\n\r\nRINGING\r'
''              \rAT
TIMEOUT         12

OK              ATE1
OK              'AT+cgdcont=1,"IP","aircelgprs"'
OK              ATD*99***1#
Note- In place of aircelgprs you have to put in your APN.
Now save and exit.

8. Now type in

Code:
$ sudo gedit /etc/chatscripts/aircel-disconnect
And enter the following

Code:
# Aircel PPP DISCONNECT script
ABORT        "BUSY"        
ABORT        "ERROR"        
ABORT        "NO DIALTONE"    
SAY        "\nSending break to the modem\n"    
""        "\K"        
""        "\K"        
""        "\K"        
""        "+++ATH"    
""        "+++ATH"    
""        "+++ATH"    
SAY        "\nPDP context detached\n"
Save and exit.

Now we are ready to connect to internet! for first time

9. Open terminal and type in

Code:
$ sudo rfcomm connect 0
Don't close this terminal and open another terminal

Code:
$ sudo pon aircel
Congratulation now your phone must be connected to internet verify it by GPRS icon in your phone.
Now bring up firefox and hit any site.

10. To disconnect from internet type this in same terminal as where you typed pon aircel

Code:
$ sudo poff aircel

For Airtel users, just replace the word 'aircel' to 'airtel' everywhere in this post. And enter suitable APN in the PPP connect script mentioned above. For Airtel it would be AT+CGDCONT=1,"IP","airtelgprs.com","",0,0. Or simply, airtelgprs.com for Nokia users.

Please comment if you have problems.

China first attacked and hacked Google. Then Google banned its services. China banned Facebook for a while. Followed by Twitter. Then the whistle-blower site Wikileaks. And many more popular websites. Reasons may be particular. But website and people who use them are sufferers. Latest entry to the list is Skype.

According to The People’s Daily, a newspaper run by Chinese Communist party, all Internet Phone Services except the two local ones, China Telecom and China Unicom, were illegal. This means that services like Skype, China’s UUCall etc. will be getting an axe soon. Chinese government have already banned websites like Facebook, Twitter and Youtube all over the country.

The ministry also set up a hotline to collect reports and distributing PSA circulars.

“Currently, our ministry is working with relevant departments to focus on the crackdown on illegal VoIP & we are now appealing to the public for clues for illegal VoIP cases,” it said in a circular.

Although, Wang Yuquan(a chief consultant at Frost and Sullivan in Beijing) said that the notice is just a warning to companies like Skype not to grow too big or to challenge the state-owned telecom service providers.

“If the ministry hadn’t made this announcement, I think Skype would have offered its services in a very large scale. Now, with the announcement, it can’t,” he said told AP.

There are over 450 million internet users in China, therefore, this would be very difficult to enforce, since users can simply download Skype or any other application from websites outside China.

There is no shutting-down action from the Chinese Ministry of IT so far, Skype is still available for use in China for the time being. Users in China currently can access Skype via TOM Online, the majority JV partner. TOM Online offers local versions of Skype for Windows, MAC as well as mobile platforms such as Symbian and Windows Mobile.
