IE8 Faster than Firefox 3.05 and Chrome 1.0


At the end of the past week, Microsoft made available to the public the results of a “browser measuring contest” involving Internet Explorer 8, Firefox 3.05 and Google Chrome 1.0. What the Redmond company did was to measure the browser load times for the top 25 websites worldwide. In the software company’s own comparison, IE8 managed to come out on top of its rivals, besting the open source Firefox and Chrome which were released in 2008, and not the current 3.1/3.5 version of Firefox or the 2.0 flavor of Chrome. But the real question is does it matter?

Obviously, Microsoft is rather a new comer to the browser measuring game. Simply because Internet Explorer, while considered by rival browser makers a reference point, never actually needed to compare itself to competitive products, especially from the perspective of the dominant browser on the market. IE continues to account for the lion’s share when it comes down to browser usage share worldwide, but Firefox has made a dent in its dominance that is harder and harder to ignore. And fact is that for the first time in the long life of Internet Explorer, Microsoft has a release that it’s worth comparing, as it is bound to score at least on par with rivals, if not even best them in certain scenarios.

“Did you know that IE 8 Loads faster than Firefox 3.05 and Chrome 1.0 on the top 25 popular web sites? Is the faster on 5 out of the top 10 sites; 12 of the top 25; 3 times as many as Firefox; and 1/3 more than Chrome,” revealed Microsoft’s Rob Margel. The table included on the left, from the “Measuring Browser Performance: Understanding issues in benchmarking and performance analysis” study, contains all the results published by Microsoft.

“In line with the testing guidelines outlined in this paper we have used the browser “Done” indicator for timing when the page is completely loaded at that point. For pages which continue to load and change after the “Done” indication we have used common visual cues to generate the timings. Timing is started when the Go button is pressed. These timings were captured in January 2009; because Internet content is always changing you may get different timings when you run these tests,” Microsoft revealed.

The question remains. Does it matter that Google.com is loaded in 0.28 seconds by Chrome, 0.22 seconds by Firefox and 0.20 seconds by IE8? What does a mere 0.02-second difference in browser load times represent to the end user? Well, absolutely nothing. You would need a high speed camera just to notice the difference. And at the same time, differences such as 5.48 seconds for Chrome, 6.37 seconds for Firefox and 8.03 seconds for IE8 when loading Sina.com.cn are more than visible, and irking to the end users. Still, what Microsoft does is establishing that benchmarking is in no way representative of real-life.

“Many benchmarking tests cite results from tools such as SunSpider, Celtic Kane, V8 and iBench. Each is designed, at least in some way, to test only a portion of the end-user scenario. SunSpider primarily tests JavaScript performance and also some other popular functions used on websites today. Other popular benchmarks, Celtic Kane and V8, are also geared at testing only the JavaScript engine. Meanwhile, the iBench suite relies on a browser reporting when it’s finished loading a page. Since browsers differ on when they define a page is done loading, this test also yields unreliable results,” the company stated.

Fact is that any measurement performed involving browsers has to take into account a multitude of variables from caching behavior, to overhead and resource competition, but also connectivity and network device latency, Internet-based data, browser-targeted content, machine configurations, inconsistent definitions, and even extensibility. In this context, benchmarks and benchmark results remain largely a marketing tool more than anything else. Due to the sometimes minute differences between the browser load times in the tests performed by Microsoft, with some minor tweaks, rival browser makers Mozilla and Google could turn the same set of tests to their advantage easily. Such a situation certainly diminishes the relevance of browser measuring contests.

10 tips For Setting Up A Wired Or Wireless Home Network

Setting up a wired or wireless home network has many benefits than just having Internet access for multiple computers
in your home. Today, it’s almost a necessity to be able to plug in or connect via wireless to your network from any room in your house.

With many people who set up a home network, they end up under utilizing their home network and only use it for Internet access, attached to one computer.

Today, that kind of network setup is old school. Adding a router to your network, turns a home network into a LAN (Local Area Network) opening up many possibilities of what you can do on your network. Even if you have just have one Computer, many devices exist (other than computers) that are network capable, allowing interaction with other.

So what can you do with all this technology? Here are ten uses for what you can do on your home network.

1. File sharing – Sharing files over your network, between computers and devices gives you more flexibility than using USB drives or burning CD’s. Having the convenience of sharing photos, music files, and documents allows for more productivity. You can also use your home network to save copies of all of your important data on a different computer.

Backups are one of the most critical, yet overlooked tasks with computers. On a home network, it’s easier than ever to backup your data especially if you have an old computer with a lot of hard drive space that can be utilized. Better yet, devices that serve one purpose for file sharing, such as a NAS (Network Attached Storage) can also be a great solution for backups as well.

2. Video Game Consoles – Games consoles such as Nintendo Wii, Microsofts XBox and Sony’s Playstation are all network capable (wireless or wired via USB to Ethernet adapter) that let you connect to your home network and quickly get online. And don’t forget about hand-held games. Many of them are network capable as well (be careful since some only support WEP encryption).

3. Print And Peripheral Functionality – Once a home network is in place, after file sharing, printing is usually the next popular function you will want to setup. It’s easy to set up all of the computers to share a single printer, or you can purchase a printer that is network capable (no need to share printers from one computer). Gone are the days of using one computer just to print out a document or an email message.

Printers are not the only peripheral that you can use on your network. Scanners, Web cams, CD burners, etc are now available with built in network support increasing the functionality of a home network. Now you can tell your boss you are more productive working from home, because your network is more reliable and has fewer network outages.

4. Internet Appliances – Yes we are now entering the Jetsons age. Also known as smart appliances, these devices still have not caught on with the average house hold but manufacturers are now starting to incorporate the technology into appliances more now than in the past. Ranging from being able to turn on you washer or oven from the Internet to saving energy, sending commands to….your refrigerator remotely….still takes a bit getting used to (who would have thought remote controls would be beneficial to TV’s that only received 6 channels).

Soon internet appliances will be a “must have toy” and another reason why a home network is not just for computers.

5. Internet Faxing – Apparently the Internet and email didn’t kill faxing. It’s now as popular as ever with the many online faxing services available. In this era of paperless offices and digital documents, you’d think the paper and ink fax machine might finally be ready to retire.

But faxing is still an essential part of doing business for certain types of documents (think legal contracts as an example). No more stringing phone lines across your dining room or hitting your head in the crawl space to run a phone line over to your fax machine. Using an online fax services is cheap these days and allows you send any kind of document from email or other programs electronically to a fax machine.

6. Internet Telephone Service – Termed Voice over IP (VoIP) service, allows you to make and receive phone calls through your home network across the Internet, saving you money (substantually). These days quality of services has improved greatly to make switching from the old analog lines to digital, a no-brainier. Soon, everyone will be using VOIP. And when that day comes, imagine how you can fight back at telemarketers. Instead of hanging up on them, you’ll be able to ping them to death (DOS). Yeahhhh!

7. Home Entertainment – Newer home entertainment products such as digital video recorders (DVRs) media centers and home theaters, now support either wired or wireless home networking. Having these products integrated into your network enables audio and video sharing, media to be streamed and easy transfer of digital files between devices.

8. PDA’s – Blackberries, cell phones, iPODs, MP3 players and any other PDA you can think of either have or will have networking functionality built in (mostly wireless). These devices are quickly taking over the use of a personal computer, one application at a time. Having a home network that these devices can connect to, makes transferring files, or streaming media to and from much more useful than connecting to a USB cable.

9. Telecommuting – Sure, you may think having one computer that is connected directly to the Internet (via cable, DSL, etc) is all you need to telecommute for work. But in reality, companies these days are requiring you to use a company supplied desktop or laptop for working at home. With out a home network that you can just easily connect to, you’ll need to always swap the Internet connection between computers. Having the flexibilty to just plug in is much more convenient and won’t make you late for work.

10. Mobility – The freedom of not being tethered to a physical connection is one big reason to set up your home network as wireless. Even if you do have a wired network, with all the network ready devices in your home, you can still have the freedom of mobility, since you can go from room to room and just plug in (providing you have run a connection to each room).

One other good reason to have a home network, is the future. Think about ten to fifteen years ago with cable TV. Who knew back then it would be one way to connect you to the world.

Robot tells us how we decide to trust strangers




American researchers are using a robot to find out how humans decide to trust strangers and if those decisions are accurate.


Northeastern University psychology professor David DeSteno is collaborating with Cynthia Breazeal, director of the MIT Media Lab’s Personal Robots Group, Robert Frank, an economist, and David Pizarro, a psychologist, both from Cornell, for the interdisciplinary research.

The team is examining whether nonverbal cues and gestures could affect our trustworthiness judgments.
DeSteno said: "People tend to mimic each other’s body language which might help them develop intuitions about what other people are feeling - intuitions about whether they’ll treat them fairly."

This project tests their theories by having humans interact with the social robot, Nexi, in an attempt to judge her trustworthiness. Unbeknownst to participants, Nexi has been programmed to make gestures while speaking with selected participants - gestures that the team hypothesizes could determine whether or not she’s deemed trustworthy.

DeSteno said: "Using a humanoid robot whose every expression and gesture we can control will allow us to better identify the exact cues and psychological processes that underlie humans’ ability to accurately predict if a stranger is trustworthy."

During the first part of the experiment, Nexi makes small talk with her human counterpart for 10 minutes, asking and answering questions about topics such as travelling, where they are from and what they like most about living in Boston.

DeSteno said: "The goal was to simulate a normal conversation with accompanying movements to see what the mind would intuitively glean about the trustworthiness of another.”

The participants then play an economic game called "Give Some," which asks them to determine how much money Nexi might give them at the expense of her individual profit. Simultaneously, they decide how much, if any, they’ll give to Nexi. The rules of the game allow for two distinct outcomes: higher individual profit for one and loss for the other, or relatively smaller and equal profits for both partners.

DeSteno said: "Trust might not be determined by one isolated gesture, but rather a ‘dance’ that happens between the strangers, which leads them to trust or not trust the other."

The team will continue testing their theories by seeing if Nexi can be taught to predict the trustworthiness of human partners.
