Today Joojen from Nanjing introduced Sogou Pinyin - a popular Chinese character input method editor developed by Sogou, a Chinese search engine.
I have been using Microsoft default pinyin and recently has just switched to the Google Pinyin. However, Sogou Pinyin impress me much! The speed and precision is really excellent!
By the way, Sogou Pinyin can be downloaded for free from http://www.sogou.com/pinyin/.

Problem installing Google Talk on Vista
Recently I faced the following when installing Google Talk in my Vista machine:
"The new version of Google Talk cannot be installed because you are running an older version of Google Talk that is not compatible with Windows Vista. Please uninstall Google Talk as Administrator to remove the incompatible version and re-install Google Talk from http://www.google.com/talk."Have tried many ways to overcome this problem but failed so far ...

Cisco DHCP Configuration
Dynamic Host Configuration Protocol (DHCP) is one of the most popular TCP/IP protocol uses today. It is used by networked devices to obtain information required to operate on an Internet Protocol network. These information may include
When a DHCP client is first switched on, it sends a broadcast packet on the network with a DHCP request. If there is a DHCP server exists in the network, this request will be picked up by the DHCP server. The DHCP server will allocate an IP address to the PC, from one of the pools of addresses it managed.
- IP address
- Default gateway
- DNS server address

What is Windows Clustering
Clustering is the connection of multiple devices together in such a way that to the outside world, the cluster appears to be a single system. Each device in a cluster is referred to as a node.
If critical service is unavailable, business will suffer. A properly installed and configured cluster provides continued operation during hardware and software failure, and/or planned maintenance. Ability to recover from failed server hardware and failed software is the main benefit of clustering.
Windows Server 2003 clustering consists of two different technologies: Server Cluster and Network Load Balancing (NLB). Each of these technologies can be used to provide high availability for different types of services.
Server Cluster is primarily used to provide availability for mission critical applications through fail-over. It is typically used for databases, e-mail services and custom applications. Windows 2003 supports server clusters of up to eight nodes. Most clustered applications, and their associated resources, are assigned to one cluster node at a time. Node failure in a cluster is detected by the absence of heartbeats from that node. If a node fails to transmit a heartbeat packet for a designated period of time, that node is considered to have failed and the remaining nodes will takeover the work load of the failed node. In this case, the clustered application will be started on remaining nodes. Client requests are immediately redirected to the backup cluster node and the impact of the failure will be minimized.

Chrome - Google's browser
Google has just released an open source browser - Google Chrome. It is now available at http://www.google.com/chrome. As with other Google application, it is available freely to the public.
In my tests, Chrome performed excellent in access to Gmail, Blogger page and so on. Each time launching a new tab, Chrome will show a customised homepage with graphical list of all recent visited websites. The address bar is really a google search engine - suggestions from Google search index pop up as I type URL in it. This smart predictive searching is really effective!
This new browser will surely become the top alternative to Internet Explorer and also Firefox.
