Gmail desktop notifications let you know when you have a new email or Chat message. When you enable these notifications, you'll see a pop-up when new messages arrive so that even if you're not looking at your Gmail, you'll still know when someone wants to talk to you. For now, these notifications are available only if you use Google Chrome as your browser.

Chat notifications are enabled by default, but you can disable them in your Gmail settings. To enable or disable email or Chat notifications, follow these steps:

Click the gear icon in the upper-right corner of Gmail, and then select Mail settings.
On the General tab, select the option you'd like in the Desktop Notifications section. You'll be able to turn Chat notifications on or off, and can also choose to turn email notifications off, receive notifications for all incoming email, or only those Gmail marks 'important'.
Click Save.

Secure surfing internet with https

Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol with the SSL/TLS protocol to provide encrypted communication and secure identification of a network web server. HTTPS connections are often used for payment transactions on the World Wide Web and for sensitive transactions in corporate information systems. HTTPS should not be confused with Secure HTTP (S-HTTP) specified in RFC 2660.

Some site doesn't support https .Some service in some site doesn't support https too.

https://encrypted.google.com/webhp?hl=en
https://mail.google.com
https://www.google.com/reader/view/

some browser have extension that force https

for Google Chrome
https://chrome.google.com/webstore/detail/obfehkohhfbooodomcfenbhaobpeddcl
https://chrome.google.com/webstore/detail/lgpkjjingioekjianemgdobchenebhek

for Firefox
https://www.eff.org/deeplinks/2010/06/encrypt-web-https-everywhere-firefox-extension but this extension isn't in the official firefox extension site so careful to install it.

The trust inherent in HTTPS is based on major certificate authorities that come pre-installed in browser software (this is equivalent to saying "I trust certificate authority (e.g. VeriSign/Microsoft/etc.) to tell me whom I should trust"). Therefore an HTTPS connection to a website can be trusted if and only if all of the following are true:

The user trusts that their browser software correctly implements HTTPS with correctly pre-installed certificate authorities.
The user trusts the certificate authority to vouch only for legitimate websites without misleading names.
The website provides a valid certificate, which means it was signed by a trusted authority. (an invalid certificate shows a warning in most browsers)
The certificate correctly identifies the website (e.g. visiting https://example and receiving a certificate for "Example Inc." and not anything else [see above]).
Either the intervening hops on the Internet are trustworthy, or the user trusts the protocol's encryption layer (TLS or SSL) is unbreakable by an eavesdropper.

Browser integration

When connecting to a site with an invalid certificate, older browsers would present the user with a dialog box asking if they wanted to continue. Newer browsers display a warning across the entire window. Newer browsers also prominently display the site's security information in the address bar.

Extended validation certificates turn the address bar green in newer browsers. Most browsers also display a warning to the user when visiting a site that contains a mixture of encrypted and unencrypted content.

Most web browsers alert the user when visiting sites that have invalid security certificates. This example is from Firefox.

Difference from HTTP

As opposed to HTTP URLs that begin with "http://" and use port 80 by default, HTTPS URLs begin with "https://" and use port 443 by default.

HTTP is unsecured and is subject to man-in-the-middle and eavesdropping attacks, which can let attackers gain access to website accounts and sensitive information. HTTPS is designed to withstand such attacks and is considered secure against such attacks (with the exception of older deprecated versions of SSL).

[edit]Network layers

HTTP operates at the highest layer of the OSI Model, the Application layer; but the security protocol operates at a lower sublayer, encrypting an HTTP message prior to transmission and decrypting a message upon arrival. Strictly speaking, HTTPS is not a separate protocol, but refers to use of ordinary HTTP over an encrypted Secure Sockets Layer (SSL) or Transport Layer Security (TLS) connection.

Everything in the HTTP message is encrypted, including the headers, and the request/response load. With the exception of the possible CCA cryptographic attack described in limitations section below, the attacker can only know the fact that a connection is taking place between the two, known to him, parties; the domain name and IP addresses.

[edit]Server setup

To prepare a web server to accept HTTPS connections, the administrator must create a public key certificate for the web server. This certificate must be signed by a trusted certificate authority for the web browser to accept it. The authority certifies that the certificate holder is indeed the entity it claims to be. Web browsers are generally distributed with the signing certificates of major certificate authorities so that they can verify certificates signed by them.

[edit]Acquiring certificates

Authoritatively signed certificates may be free^[3]^[4] or cost between US$13^[5] and $1,500^[6] per year.

Organizations may also run their own certificate authority, particularly if they are responsible for setting up browsers to access their own sites (for example, sites on a company intranet, or major universities). They can easily add copies of their own signing certificate to the trusted certificates distributed with the browser.

There also exists a peer-to-peer certificate authority, CACert.

[edit]Use as access control

The system can also be used for client authentication in order to limit access to a web server to authorized users. To do this, the site administrator typically creates a certificate for each user, a certificate that is loaded into his/her browser. Normally, that contains the name and e-mail address of the authorized user and is automatically checked by the server on each reconnect to verify the user's identity, potentially without even entering a password.

In case of compromised private key

A certificate may be revoked before it expires, for example because the secrecy of the private key has been compromised. Newer versions of popular browsers such as Google Chrome, Firefox,^[7]Opera,^[8] and Internet Explorer on Windows Vista^[9] implement the Online Certificate Status Protocol (OCSP) to verify that this is not the case. The browser sends the certificate's serial number to the certificate authority or its delegate via OCSP and the authority responds, telling the browser whether or not the certificate is still valid.^[10]

สำหรับการเปิดให้ดาวน์โหลดในครั้งนี้จะมีทั้งหมด 4 เวอร์ชันด้วยกัน ได้แก่ เวอร์ชันสำหรับ Windows 7, Windows Vista และ Windows Server 2008, Windows Vista 64-bit และ Windows Server 2008 64-bit และ Windows 7 64-bit และ Windows Server 2008 R2 64-bit โดยที่ไม่มีเวอร์ชันสำหรับ Windows XP แต่อย่างใด ทั้งนี้สามารถดาวน์โหลดมาทดลองใช้งานได้จากเว็บไซต์ดังต่อไปนี้
• Windows Internet Explorer 9 Beta for Windows 7
• Windows Internet Explorer 9 Beta for Windows Vista and Windows Server 2008
• Windows Internet Explorer 9 Beta for Windows Vista 64-bit Edition and Windows Server 2008 64-bit Edition
• Windows Internet Explorer 9 Beta for Windows 7 64-bit Edition and Windows Server 2008 R2 64-bit Edition

To verify the results, I ran my recent JavaScript string concatenation test and it was even more bizarre:

IE9 32-bit string concatenation operator: 5ms
IE9 32-bit array join: 630ms
IE9 64-bit string concatenation operator: 12ms
IE9 64-bit array join: 1,025ms

Concatenation operators in IE9 are faster than IE8, but array joins are significantly worse — around 10 times slower. And why is the 32-bit IE9 twice as fast as the 64-bit edition on a 64-bit OS?
