Comment on "Serious Potential in Google’s Browser"

As the title of the article said "Serious Potential in Google’s Browser", based on my experience using Chrome there is a potential in Chrome. There are some advantages in Chrome that IE 8 (the newest edition of IE) and Firefox doesn't have, such as animation when moving the tabs or make the tab as a new window, each tab has its memory, cover its contents if there's a bug then won't infects the other tabs open at that time. 
When the browser start slow, we can check which website that eats a lot of memory by using Task Manager. Because Chrome makes each tab independently. The speed of using Chrome and Firefox almost need the same time, but compare with IE 8, I think Chrome faster twice like the article said.
The interface of Chrome is simply but almost powerful like Firefox. No main menu only two buttons, about file and settings. Then only has one toolbar for bookmarks. I think this interface makes Chrome faster.
The other advantage of Chrome is when type an url, Chrome give suggestions about the url type on the address bar. This advantage makes users save time for typing urls. Chrome also save history about the pages that ever visited and when open a new tab or window, there will be nine mini boxes show what pages that usually users visit.
This Chrome sometimes not works on some website. For example, in a website which is contains movie (not Youtube), Chrome can't play the movie. The movie is using swf player, maybe Chrome doesn't have plug-in of swf. This will be correction for Chrome developer update the browser and will be become powerfull or like the title said 'Potential'.
Overall, Google's web browser, Chrome, give a good point in the earlier version. More faster and easy to use.

Chrome vs Firefox


Comparing the performance of Google Chrome and Mozilla Firefox has purpose which one is good to use, faster, and user friendly.
Reflect from windows Task Manager, Firefox eats a lot of memory. For Chrome, each tab we open has its own memory. This is the advantage using Chrome that it is ability to handle tabs in independent processes which means a browser or plugin bug, or an incorrectly coded web page can’t take down the whole browser, but just that tab or plugin alone
Picture above is from my notebook (Intel 2GHz 2MB L2 Cache, 1 GB DDR2) and open the same website on Chrome and Firefox.
When open youtube, blogspot, msn, yahoo, they need almost same time to open. From my experience when open youtube, Chrome faster in buffering rather than Firefox. Sometimes Firefox said "We're sorry, this video no longer available", but in Chrome the same address can play the video. For the others example, they are almost the same when using Chrome or Firefox. Then, I tried another address which is for watch movies on both web browser. On Firefox the url works, but on Chrome it wasn't work only show a text said "[global loading]". I think because Chrome doesn't have plug-in (for this case is swf player) now, not like Firefox which is integrate with swf player. Maybe, Google will come new update with more integration inside the browser.
In addition, the interface between Chrome and Firefox is different. Chrome more snappy, it doesn't have main menu,  status bar is overlaid at the bottom when needed, just like the find bar; no search bar which is integrated with the location bar, it has a new tab button, it has cool animations when accessing the bookmarks toolbar or moving tabs which definitely helps feel the browser more responsive.

Homework, 9-27-2008

1. Install Google Browser Google Chrome and Firefox 3.0, try a few websites and compare their performance. For example, youtube, blogspot, msn, and yahoo.

2. Subscribe to our course website by Google reader, put the Google reader block on your iGoogle.
Done, as the image below.

3. Comment on the article Serious potential in Google's Browser

4. Watch the video recording of Larry Page's "Broadband for the future."
done.

Kai-Fu Lee, www Conference Talk 2008, "Cloud Computing"

Cloud computing is an abstract server and move anywhere and scalable. Cloud computing is the future of computing.
What do peoples want from internet? Peoples want freedom, want their data anywhere they are. They want easy to learn and easy to use, especially their own data to be secure and not lost. People are using cloud services to find, share, create, and organize information. Cloud computing will be accessible not only on PCs but also telephones, automobiles, televisions, and appliances.
There are 4 attributes that solves users' problem: Data stored on the cloud (cloud here means some servers that user don't know), Software services on the cloud (access via web browser), Based on standards and protocols (such as Linux, Ajax, LAMP), and Accessible from any device, especially phones. Cloud computing has 6 properties from Google's perspective :
1. User centric : Data that stored in cloud is yours also can share with others.
2. Task centric : Combine some applications in one application (For example Gmail integrates a chat feature for instant communication.)
3. Powerful : It can do that PC can't do
4. Accessible : can instantly get more information from different repositories.
5. Intelligent : massive data storage + massive data analysis = Google Intelligence
6. Programmable : Every piece of data is replicated three times. (Google's infrastructure)

Summary : Evolutions of Cellular Phones by Nokia

The introduction of communication is dramatically changing our lives. The ability to communicate anytime, anywhere increases our quality of lives and improves our business productivity. Since invention "Talk to a box" in 1876 then people start to have more intensely to develop or invent in communication system. After "Talk to a box" in 1876, "Listen to a box" in 1896, "Watch a box" in 1925, "Command a box" in 1944, "Take the box with you" in 1980s. In 1996-2006, many applications are invented and developed. Nowadays peoples use the box to listen to the world, recording everything (what we see, say, feel, hear, etc.).
There's one dimension that Tirri (Researcher at Nokia) mentioned in Conference, PerComm 2007, is Participatory Sensing. The new invention is that mobile phones can show the Air Pollution tracking data (EPA), see the traffic using GPS, location of the car in parking lot, sports performance. Tirri said 5 keys technological challenges, they are Sensor data, Mobile connectivity, Integration, Power, and Scaling down.
The rise of mobile telephony gives us the chance to observe the adoption of a new technology. Beyond providing insight into innovation, it affords us the chance to see how the innovation is accepted and how it causes the revision of existing values and practices.
