Attack Of The Killer Web Robots

They swarm the Internet harvesting e-mail addresses and free accounts to spawn hoards of junk messages. They lurk in chat rooms waiting to sting unsuspecting surfers with gambling sites, get-rich-quick schemes and pornography.

But these automated computer programs – known as Web robots – have what may be a fatal flaw: For all their ability to seem otherwise, they’re not human.

So researchers at Carnegie Mellon University are designing software that can serve as an online gatekeeper. If you can’t prove you’re human, you won’t get in.

The method involves a new breed of the Turing test used to distinguish real people from intelligent computer programs. Researchers term these tests “captchas” – shorthand for “completely automated public Turing tests to tell computers and humans apart.”

Apple Revamps MacBook notebook computers

CUPERTINO, Calif.

Apple Inc. said Tuesday it revamped its MacBook and MacBook Pro notebook computers with new processors, larger hard drives and more memory.

The company has added more sophisticated Intel processor chips and 2 gigabytes of memory in most models.

MacBook Pro will come with Nvidia graphic processor chips and added video memory.

Nvidia is best known for making graphic chips used for video games and other electronic entertainment.

All Mac notebooks will include video cameras for video conferencing and prices will start at $1,099. The notebooks are currently being shipped and will be available through retailers and Apple’s Web site.

Nvidia releases first 9000 series card

The 9600 GT, the first new generation of graphics cards, was released on Feburary 22, 2008. It is the first of this new series, but the preformance of the card is poor compared to their other recent card, the 8800 gt. Nvidia says that they will also be releasing a 9800 gtx and a 9800 gx2, but they have not set any information on the release. Hopefully, they will be a big step from the 8800’s that still seem to be dominant.

“The NVIDIA® GeForce® 9600 GT GPU offers a powerfully immersive entertainment experience designed for extreme high-definition gaming and video playback. Play the hottest DirectX 10 games with awesome speed and watch the latest HD DVD and Blu-ray movies with brilliant clarity. Featuring next generation GeForce and PureVideo® HD technologies, the GeForce 9600 GT GPU puts amazing graphics performance within your reach.” -http://www.nvidia.com/object/geforce_9600gt.html

Reflect on your brief encounter with LeGO Robotics.

What did you enjoy about the kits?

What did you learn?

What is your advice for what to do with these kits next year?

Cingular Wireless on Tuesday launched its third-generation network, which it says will give mobile customers high-speed Internet access while on the road.

The new service, called BroadbandConnect, will be available in 16 markets to nearly 35 million people in 52 communities throughout the United States. Cingular, which is jointly owned by BellSouth and AT&T, plans to continue to extend the network throughout 2006. 

“Make no mistake about it: Wireless users want the speed and services they’ve come to expect from their wired connections,” Stan Sigman, Cingular’s president and CEO, said in a statement at an investor conference in New York on Tuesday. “And today, Cingular is delivering on its promises to provide both the speed and reliability customers need.” 

Cingular’s 3G network uses a technology called HSDPA (High Speed Downlink Packet Access), which is a combination of GSM (Global System for Mobile Communications) and EDGE (Enhanced Data for GSM Environment). It provides average mobile data download connections between 400 kilobits per second and 700kbps. 

Using a laptop modem card that costs about $100 with a qualifying voice plan, Cingular customers can use their laptops to access the Internet or e-mail, download large files and attachments, and run corporate business applications in areas covered by BroadbandConnect. 

Customers can sign up for an introductory two-year contract for $59.99, which gives unlimited usage. Other monthly plans are available starting at $19.99 for 5 megabytes of data. Cingular also said it plans to enhance the network to deliver full-motion video and audio sometime in 2006. 

Initially, BroadbandConnect will be available only on laptops. But the company plans to announce handset support early in 2006, Ralph de la Vega, chief operating officer at Cingular, told journalists and analysts during a conference call on Tuesday. The company also plans to announce several new services in the next several weeks that will take advantage of the new network, he said. 

After spending billions of dollars to upgrade networks, cellular operators are starting to duke it out for mobile customers looking for high-speed broadband services. Verizon Wireless and Sprint Nextel, which both use a technology called EV-DO, already offer data services over their 3G networks on handsets. 

Cingular claims that it has an edge over these other providers. For one, it says that BroadbandConnect’s modems are compatible with its older EDGE/GPRS network. As result, if customers wander outside the new 3G network, the modem automatically switches over to the slower EDGE network. 

“The (service is) seamless,” said de la Vega. “It will continue without users reinitiating the call no matter where they are. The speeds will be slower, but the services will still operate over the EDGE network.” 

Cingular’s EDGE network is available in more than 13,000 cities and towns and in areas along 40,000 miles of highways, providing average data speeds between 70kbps and 135kbps. Cingular customers can also access data services in more than 90 countries. 

Cingular will initially launch the BroadbandConnect service in Austin, Texas; Baltimore, Md.; Boston; Chicago; Dallas; Houston; Las Vegas; Phoenix; Portland, Ore.; Salt Lake City; San Diego; San Francisco; San Jose, Calif.; Seattle and Tacoma, Wash.; and Washington. 

Google Open Source coding contest

Google has begun an open source coding contest for coders who are pre-university (ages 13- college). There are a number of possibilities for involvement; check the contest rules, etc. at

So, why are you here?

Welcome, and thanks for being part of the 07-08 programming class! I know why I am here, but I don’t know why you are….., and I realize that being a programmer is not the end goal for all of the students in this course.
Please comment and share your goals. Why are you here? How did you get here (what prior experiences qualified you for entrance into this class)?

Desktop and webpage gadgets

I don’t know about you, but I love Google’s desktop and webpage gadgets. Sports scores and news come right to my desktop, while the picture viewer shows small versions of all the images on my computer. If a particular image (or score or news short) catches my eye and interests me, I can maximize or follow the link.

All of these gadgets (calculators, calendars, weather, pacman, etc. ) were built by folks just like you and me. How do they do it? http://code.google.com/support/bin/topic.py?topic=10033

Be the first El Diamante student to have YOUR gadget added to the Google collection.

Class Evaluation

Here is where I need your input for designing next year’s course. Please comment on the following (you may comment to the blog, or leave me a printed copy- your name is not required):

Overall flow of the course (made sense, too fast or slow, etc.)

Specific areas:

Javascript

LOGO

Visual Basic

Java

Use of this Blog

CODE Chapter Summaries and homework

Do you think the course would benefit from the addition of a Robotics unit?
