One more day to go and school will be out, today we are going to take the programming part of the test. Here is some information from http://www.sci-tech-today.com/story.xhtml?story_id=31328

Gadget of the Week: Assistive Mouse Adapter

Posted March 16, 2005 1:10PM

IBM's assistive mouse adapter filters out the shaking movements of the hand in a manner similar to the way camera lens stabilizing systems work. It also can filter out unintended multiple clicking caused by a shaking finger.

For the 3 million people in the UK who suffer from a form of tremor condition, such as Parkinson's, using a computer mouse is anything but easy.
The assistive mouse adapter was invented by IBM researcher Jim Levine after he saw his uncle, a Parkinson's sufferer, struggle with using a computer mouse.

"I knew that there must be a way to improve the situation for him and other tremor sufferers around the world, including the elderly," says Levine.

The device is plugged in between the computer and the mouse and can be adjusted depending on the tremor severity.

It can also filter out unintended multiple clicking caused by a shaking finger. It filters out the shaking movements of the hand in a similar way to the stabilising systems of many camera lenses.

It may look simple, but for millions of people, the assistive mouse adapter may be a mechanical miracle.

WebTV Virus Writer Sentenced to Prison

Virus had caused WebTV users to dial 911 instead of their local access number.

A Louisiana man was sentenced to six months in prison for sending a malicious program using e-mail that caused Microsoft WebTV customers to call the 911 emergency service without their knowledge, according to a statement released by the U.S. Attorney's Office for the Northern District of California.

David Jeansonne, 44, pled guilty in February to charges of intentionally causing damage to computers and causing a threat to public safety.

He was sentenced on Monday by U.S. District Judge Ronald Whyte and will have to spend an additional six months of home detention and pay $27,100 to Microsoft after he is released, the U.S. Attorney's Office says.

WebTV, which is now known as MSN TV, is a Microsoft service that allows subscribers to browse the Web and connect to the Internet through their television sets.


Malicious E-Mail
In July 2002, Jeansonne sent out e-mail messages to around 20 WebTV subscribers with an attachment that he claimed would change the WebTV display colors when opened. The attachment was actually a computer script that reprogrammed the recipient's WebTV box to dial 911 instead of the local telephone number to access Microsoft's WebTV servers.

Around 10 users fell for the ruse, and local police departments around the country responded, sending officers to the homes of WebTV users in response to the 911 calls.

Jeansonne was caught following an investigation by the Federal Bureau of Investigation and prosecuted by the Computer Hacking and Intellectual Property (CHIP) Unit of the United States Attorney's Office.

Apple wins trade secrets lawsuit
Ruling forces online reporters to divulge sources

posted 10:27am EST Mon Mar 14 2005 - submitted by Brian Osborne
NEWS
In a decision that is expected to have a "chilling" effect on leaks about upcoming product releases, a California judge ruled that three online reporters must divulge their sources regarding a product code-named "Asteroid." The ruling comes as a result of a lawsuit filed by Apple against those responsible for publishing online what the company considers to be trade secrets.

According to an AppleInsider article (and one at PowerPage), Asteroid was rumored to be a device that would allow a user to connect external instruments or other audio devices to an Apple computer for use with the GarageBand 2.0 music studio application. It is Apple's belief that the websites' reporting on the Asteroid device violated California's Uniform Trade Secrets Act and non-disclosure agreements, while the three reporters who wrote the article contend that their actions are protected under the first amendment.

Apple also claimed that the authors of the articles were not journalists, but "merely people who disseminated product releases and other data, adding little analysis or journalistic context." The presiding judge, Santa Clara County Superior Court Judge James Kleinberg, declined to say whether the three were journalists or not, but wrote that even if they were, "The journalist's privilege is not absolute. For example, journalists cannot refuse to disclose information when it relates to a crime."

The three reporters are being represented by an attorney from the Electronic Frontier Foundation (EFF). The attorney, Kurt Opsahl, stated that the ruling will be appealed.

Today I just worked on Project4 and look up some information that might be helpful for project 4 here is what I found at http://www.codeave.com/asp/code.asp?u_log=120

To see an example of the code go to the website above.

Daily Hit Counter

There are many ways to track usage of a website. The simplest way is with a hit counter, which will give you a raw count, but will not tell you how many people are visiting on any giving day. Utilizing the current date function a text document will be created utilizing the date as part of its naming convention in the same directory (providing that directory has user write access, you may need to place the documents in your cgi-bin depending on your provider) as the page we want the counter to appear on. The .txt file is first read to gain the value of the last hit count, one is added to that number, written to the .txt document, closed and the counter value is written as text to the page. If there is no text document (counter) for the current date one is automatically created. Refresh the content of the output page for a more complete illustration of the working counter.

Today I think we go over Chapter 15 so let let me share some information with you from http://www.theregister.co.uk/2005/03/10/amd_turion_launch/ website.

AMD details its Turion mobile processor

By Tony Smith
Published Thursday 10th March 2005 21:18 GMT
CeBIT 2005 AMD today introduced its Turion 64 processor, the chip it hopes will help it wrest dominance of the notebook CPU market from Intel's Centrino.

The chip family provides much the same feature set as the 754-pin Mobile Athlon 64 for thin'n'light notebooks, such as 64-bit processing, AMD's PowerNow! power conservation system, on-board memory manager and so on. All of which suggests Turion really is just an exercise in branding. As is calling it a "Mobile Technology" rather than a mobile microprocessor.

Turion chips contain either 512KB or 1MB of on-die L2 cache. All the versions offer 128KB of L1 cache, support for a HyperTransport bus clocked at up to 1.6GHz, and the ability to deal with single-channel DDR SDRAM with ECC running at up to 400MHz.

The 90nm chips have a maximum power draw of 25 or 35W, with CPU clocks running from 1.6GHz to 2GHz. They support Intel's SSE 3 SIMD multimedia instructions, along with 'no execute' bit anti-virus support.

AMD introduced yet another model numbering scheme, separating the Turion line from both the Opteron and Athlon 64 ranges. The new chips have an 'M', for mobile, followed by a second letter, the higher up the alphabet it is, the more 'mobile' the processor, apparently. After that comes a number designed to convey how clock speed and cache size combine to give performance.

Wednesday-9

Today we went over Chapter 14 maintaining and supporting a web application. The system.diagnostics namespace provides various classes that help in managing and monitoring a web application. We focus on three of these classes the process, eventlog, and the performance counter. The process class provides information about the processes running on a computer. EventLog class allows you to read from and write to a windows event log. PerformanceCounter class can be used to get performance data for running processes. We discuss working with event logs and writing to event logs and reading performance data of running processes. We also discuss designing a web application for performance and than we worked on our projects for the rest of the class period.
