Backdoor.Win32.Clampi.a

A new backdoor trojan virus has been discovered and is known as Backdoor.Win32.Clampi.a. It is a trojan spy program designed to steal confidential data and remotely manage the victim machine. It is a Windows PE EXE file that is 470 bytes in size. It is designed to harvest information from the victim machine by connecting to servers to download and run malicious code. It is looking to steal user name, login data, program passwords, and local and network passwords. It can be configured to steal login and password data for internet banking systems by substituting spoofed pages for the genuine banking system pages. This is a very dangerous identity theft tool that can leave its victims with a terrible economic mess. If you suspect your machine has been infected with this trojan virus you can do the following to delete it from your machine:

Use Task Manager to terminate the malicious process.

Delete the original backdoor file.

Delete the file created by the backdoor:
%AppData%\.exe

Delete the following system registry key:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run]
"" = %AppData%\.exe

Update your antivirus databases and perform a full scan of you computer.

When doing any kind of online banking or using sites that require a login password, use the sites security features such as identifiable security pictures and security questions to make sure you are actually on a legitimate site. Spoof sites will try to reproduce an official looking site but lack the security measures that more and more sites are now using to protect you and your identity.

President Obama's Stand On Technology

As a senator in the United States government, Obama put forth technological ideas such as giving the public access to the day to day governmental business that takes place in Washington, D.C. through the Internet. He proposed that government data would be opened up to the public in universally accessible formats. The executive decision making process would also be opened up to the public to solicit opinions as well as tap into the expertise of the public at large on certain subjects. He believes government departments and agencies should have a transparency and that the public should be able to follow the activities and accountability of these offices through direct reporting on the Internet. The public should receive more reports on the progress of these agencies, and public participation and comments should be encouraged. Obama also proposed that Americans would be invited to comment on legislation on the President's desk for up to five days before the President signs it, allowing the citizens themselves to lobby the President directly.
Senator Obama also stated on his campaign website that he supports the basic principle that network providers should not be allowed to charge fees to privilege the content or applications of some websites and Internet applications over others. His name has appeared as a sponsor on several bills that call for the enforcement of net neutrality policies for the nation's ISP's. Obama also proposed that there should be a cabinet level chief technology officer that would be tasked with ensuring all branches are using technology in an effective manner. This person would also be responsible for the "transparency" that Obama has proposed for government.
These were lofty goals proposed by a senator seeking election. Now that Barack Obama has been elected President, he has appointed the first ever Chief Technology Officer, or Technology Czar, in an effort to improve and encourage technology innovation for the purpose of promoting government transparency and data access. This person is Aneesh Chopra and he will be in charge of developing new technology policies that will ultimately change the way we operate socially and economically. President Obama has proposed sweeping health care reform and part of this reform will be bringing Health IT into the fold to provide accuracy and cut costs for health providers. The thought behind this plan is that it will cut back on the abuse of insurance fraud and rising malpractice insurance premiums by reporting costs and procedures electronically in a standardized format. Health records would be electronically standardized as well to provide better healthcare overall. Chopra will be tasked with developing the policy and structure for this Health IT as well as providing schools with access to leading edge technology systems. Chopra has lead a technological revolution of sorts on a smaller scale in his home state of Virginia and President Obama believes he is the man to lead the United States into the future of technology like we have never seen before.
I am looking forward to what lies ahead in our technological future and hope the outcomes of these ambitious goals turn out positive for all.

Blog 12 Windows ME

Windows ME (Millennium Edition) was released December 31, 2000 as a newer version of Windows 9x to replace Windows 98. From the very beginning, it was plagued will multiple problems. A new feature of Windows ME was called System Restore which was meant to be a logging and reversion tool to allow troubleshooting and problem solving. It was intended to work as a rollback and recovery feature. System Restore suffered from a bug in the date-stamp functionality. System Restore would incorrectly date-stamp the snapshots taken after September 8, 2001 that would prevent the tool from locating these snapshots and would cause System Restore to fail. System Restore would also sometimes restore malware that the user had deleted. System restore would have to be shut down to delete the malware but then the restore points would be lost.
Windows ME restricted access to real mode MS-DOS in order to speed up booting time. This saved seconds in the booting time but applications that needed real time DOS to run such as older disk utilities, did not run under Windows ME. Windows ME had a short shelf life of just over a year and security updates and hotfixes were terminated on July 11, 2006 along with Windows 98 and Windows 98SE because Microsoft considered these products obsolete and a security risk to users running these programs.
Windows ME was criticized by users for it instability and unreliability due to frequent freezes and crashes. A PC World article dubbed Windows ME the "Mistake Edition" and placed it 4th in their "Worst Tech Products of All Time" feature. The article stated that users reported problems installing it, getting it to run, getting it to work with other hardware or software, and getting it to stop running.
I did not have the misfortune of working with Windows ME and from the many problems this OS suffered, consider myself lucky to have dodged a bullet.

Blog 11 What is Linux and who would use it?

Linux is an operating system. It was developed by a university student, Linus Torvalds of Finland in 1991. In 1994, Linux Kernel 1.0 was released and is the base around which a Linux operating system is developed. The source code is freely available to everyone. Many individuals and companies have developed their own operating systems using the Linux Kernel. Some are very specific to the needs of the individual or company and some can be used by many users. Linux distributions are copies of the many developed OS's that are available to the general public to use. Big companies such as IBM and Hewlett-Packard have devoted a lot of time and money in the development and support of Linux Operating Systems. Linux is primarily a server platform but is finding its way into home and office desktops. It can also be "embedded" directly into microchips to be used in appliances and devices. Linux's functionality and adaptability has made it a main alternative to the proprietary operating systems of Unix and Microsoft.
If you are interested in trying a Linux operating system for yourself, you can request a free download that was developed by a Linux consultant, Klaus Knopper, called Knoppix. You download it to a CD and you run the operating system from your CD drive. There is no reason to load it to your hard drive.
I would try it to see for myself what capabilities the OS has compared to the Microsoft OS that I am use to. I believe the wave of the future will lean towards a public domain of technological creation that will take us to the next level. Bill Gates is a pioneer of our current computing world but I believe a product like Linux that gives the foundation to the whole world is a powerful tool because there are people with really great ideas who need a starting point. Once these OS's are built and improved upon by many, who knows, the sky's the limit.

Blog 10 Microsoft Future Products

Microsoft has developed a video game programming software for XBOX 360 Live called Kodu. It is a new visual programming language for creating games. It is geared towards kids and allows them to create their very own video games using programs that are expressed in physical terms, using concepts like vision, hearing, and time to control character behavior. Kids use icon based tool menus to create worlds by actually building land masses, water, trees, bridges, paths, etc. The terrain editor allows them to create arbitrary worlds that are unique to each child's imagination. They then determine what characters they are going to use and what characteristics each character will have. The kids determine the rules and outcomes of the actions of each character. I think this will be a great tool to introduce kids to programming and it will pull the creativity out of their minds and make them think about what they want to create. Individualism and creative expression while learning a new skill is a good idea for products such as video games that many people consider idle wastes of time.

Blog 8 Project 8.1 Researching Floppy Drives on the Internet

What is the price of an internal floppy drive?
Internal floppy drives are advertised from$2.99 to over $100.00 with $10.00 to $15.00 as the average.

What kind of connections do external floppy disk drives use? What is the price of an external floppy drive?
External floppy drives use a USB connection. The cost averages about $25.00.

Why do you think external drives cost more than internal drives? What are the advantages of external drives? Internal drives?
I think external drives cost more because USB is a newer technology and a separate power supply is needed for the external drive. External drives are easier to install, can be interchanged among different computers, and usually have better cooling. Internal drives are cheaper to replace and you can use the tray to swap hard disks in and out without opening the case.

DMA (Direct Memory Access Channel) is a number identifying a channel which allows a device to pass data to memory without going through the CPU. It is a shortcut for moving data to and from the device and memory. This frees up the CPU and allows better performance of the CPU.

Low Level Formatting is a process performed at the factory that electronically creates the hard drive tracks and sectors. It tests for bad spots on the disk surface. With older drives, technicians would use a utility program to do this formatting. Low level formatting at the factory takes care of this task and makes today's hard drives disposable. When the sectors fail and are no longer able to read, you salvage whatever data you can and throw the drive away and replace it with a new one.

SATA (Serial ATA) is an ATAPI cabling method that uses a narrower and more reliable cable the the 80 conductor cable. This allows for better internal cooling because the thinner cables do not block air flow like the thicker 80 conductor cable does. SATA was developed to replace the older ATA standard. Devices are able to communicate much faster using a serial cable over two conductors. The older ATA standard became known as parallel ATA after SATA was developed. Parallel ATA uses 16 data conductors and is much slower. SATA reduces cable bulk and cost because it only requires seven wires instead of eighty wires. It is faster and more efficient in data transfer and allows hot swapping. Hot swapping is replacing components without shutting down the system and rebooting.

ATA (Advanced Technology Attachment) is an interface standard for the connection of storage devices such as hard disks, solid-state drives, and CD-ROM drives in computers. This evolved from the IDE interface. After SATA was developed this became known as Parallel ATA. It only allows for cable lengths up to eighteen inches. Because of this limitation, the technology normally appears as an internal computer storage interface. For many years, ATA provided the most common and least expensive interface for this application. At the beginning of 2007, ATA was largely replaced by serial ATA.

IDE (Integrated Drive Electronics or Integrated Device Electronics) is a hard drive whose disk controller is integrated into the drive which eliminates the need for a controller cable which increases speed and reduces price. IDE is the base for which technologies such as EIDE (Enhanced IDE) were developed. EIDE supports drives with over 250 GB of data and allows for data transfer rates that are over twice as fast as the original IDE. SCSI technology is faster but more expensive than EIDE but has been replaced with the newer SATA technology.

Second Life

Second Life is a 3D virtual reality world where users can create an avatar and socialize, connect and create using free voice and text chat. Users can live a fantasy life through Second Life.
I think it could be a useful tool to help people who are introverted and shy to learn how to interact and lead a normal life by exploring and doing things they would not normally do in real life.
Businesses could use it by advertising, product placement or promoting certain lifestyles or fashion trends.
Education could use it as a tool to teach social skills, or to teach someone a skill or trade through a virtual classroom or on the job training.
I would explore Second Life to see how it functions and what it is all about out of curiosity. I think there is a major downside to a site like this. Many people give up their real life and spend way too much time on the computer in chat rooms, facebook, myspace, video games, etc. My belief is why not explore what life has to offer in real time instead of wasting your life in virtual reality. In moderation I think something like this could be good entertainment but some people might become hooked and spend all of their free time living the life of a cartoon.

Innovative Tools for People with Disabilities

There are many products on the market to help people with disabilities to communicate. Two of the products that I found are the Gus! Multimedia Speech Software which converts any Windows based personal computer into a communication device. The software allows individuals to communicate by entering keystrokes into the computer that are then converted into speech. This allows people with diseases such as ALS (Lou Gehrig's Disease) and people who have had strokes to communicate over the phone and to have a conversation with someone without that person having to read what the disabled person is typing. This Software retails for $695.00.
The other product I found is the Gus! Pocket communicator X51 which is useful to people with autism, stroke, cancer, and other conditions affecting speech. It has pages of words and phrases that the disabled person can poke on that are then converted to speech. It allows the person to carry on a normal life by being able to communicate with store clerks, pharmacists, etc. This product retails for $2095.00.

Blog 5 Computer Terms

Processor frequency is the speed at which the processor operates. This frequency is determined by applying a clock multiplier to the front side bus (FSB) speed. If your processor is running at 1600MHz it has an 800MHz FSB. This means the internal clock multiplier setting is 2. The system bus frequency times the multiplier equals the processor frequency.

Word size is the number of bits a processor can process at one time. Bits are either a 0 or a 1. Eight bits equal one byte. A word is made up of a certain number of bytes. The processors that we use today us a word size of 32 bits (4 bytes) or 64 bits (8 bytes).

Overclocking is when a computer component like a CPU is made to operate beyond its intended performance levels. For example, if you decrease the amount of time it take the CPU to communicate with the North bridge, you will increase the FSB speed. Overclocking computer components can create an unstable system and can lead to problems such as overheating.

Data Path is the number of bits a processor can receive at one time. It is sometimes refered to as the external data path and is a part of the system bus that transports data into the processor. It transfers bits to the processor in a group such as 64 bits and then the processor processes the bits based on the word size it can handle. The data path and word size processing do not have to be the same size. The data path can be 64 bits but the processor can only handle 32 bit word size.

SRAM or static RAM is a small piece of memory that is much faster than regular DRAM or dynamic RAM. A processor is able to access the SRAM and do its computations much quicker because the SRAM temporarily stores recently accessed data in expectation of what the processor will do next. By accessing SRAM, the process is much faster because the processor doesn't have to search the DRAM.

Primary Cache is also known as Level 1 cache. It is the fastest memory and is built directly into the processor itself. This allows it to run at the same speed as the processor. This cache of memory is small, usually 8KB to 64 KB and holds recently used data and instructions from memory. This enables the processor to access this information quickly because it doesn't have to search the main memory.

External Cache is also known as Level 2 cache. This is a secondary cache to level 1 cache and is larger and slightly slower. It catches accesses to main memory that are not caught by level 1 cache. Level 2 cache is called external cache because it is usually found outside the processor microchip on the mother board or a daughter card on the mother board.

Memory cache is SRAM that is much faster than DRAM because SRAM does not need refreshing and can hold its data as long as the power is on. Regular RAM loses data rapidly and has to be refreshed.

HFD Series Power Supply

The power that you have in a residential outlet is usually 120V AC. When you plug your computer into an outlet in your home or office, the computer cannot run on pure AC power. The HFD series switching power supply takes the 120V AC power and reduces it with a transformer down to 5V or 12V AC. A process called rectification transforms this AC power into DC power. Your PC uses this DC power to function. The power supply adjusts the DC power based on the consumption of the device connected to it. When the PC isn't consuming a lot of power, the power supply readjusts itself to deliver less current, making the transformer and all other components dissipate less power which in turn generates less heat. Heat is a killer to PC components like the CPU and the hard drive. The less heat generated, the less wear and tear on your PC and its components. By converting the AC power to DC, smaller components such as transformers can be used instead of the much larger ones that would be required for reducing the AC to an acceptable level to run the computer.
The HFD series is a 145W Dual output switching power supply that converts 120AC to 5v and 12V. It can be purchased from Daitron, Inc. 568 E. Weddell Dr. Ste. #8 Sunnyvale, CA. This company is a subsidiary of Daito Electron Co., Ltd. of Japan where the power supplies are manufactured. The approximate cost is $188.00.

What Does The Research Say About Technology's Impact on Education?

What Does the Research Say About Technology's Impact on Education?

Two research studies were done by the Department of Education and Apple Computers Inc. on the impact technology has had on education respectively.
In the U.S. Department of Education funded study of nine schools who used the latest technology, it was concluded that the use of technology resulted in educational gains for all students regardless of age, race, socio-economic standing or any other characteristics. The study found state test scores and student attendance improved. There was also increased student comprehension, motivation, attitude, strong study habits, parent and teacher support, improved retention of material, and improved placement in jobs.
Technology enhances student achievement in a variety of ways. Multi-media software allows teaching to a variety of learning styles. Video and audio technologies bring material to life. Instead of learning in a two dimensional classroom setting, students were able to interact with the materials by using sight and sound. Distance learning has been found to be at least as effective as traditional methods of instruction. The Internet and such things as CD-ROMS and DVDs have helped students learn to organize complex information, recognize patterns, draw inferences, and communicate findings. Technology has also allowed students to learn better organizational and problem solving skills. The studies found that students are motivated by technology. They like learning better through technology than more standard means. Technology has increased family involvement and improved teachers' skills. It has also improved School Administration and Management.
In the Apple Computer, Inc. 10 year study, the results of providing students with the latest technology enabled them to perform well on standardized tests but were also helping them develop a variety of skills not usually measured. Students explored and represented information in many forms. Their confidence and social awareness increased. They learned to communicate more effectively about complex processes and became independent learners and self starters. They became comfortable with their areas of expertise and were able to share this information with fellow students. One issue the project hoped to confront was the possibility of any negative effects from prolonged exposure to computers. Some critics have worried that students who use computers extensively will become "brain dead" or less social from looking at the computer screen all day. At the end of two years, these fears were found to be false. Children did not become social isolates. The students showed more evidence of spontaneous cooperative learning than did traditional classes. Children did not become bored by the technology over time. Instead, their desire to use it for their own purposes increased with use. Even young children had no problem becoming adept users of the keyboard. With very little training, second and third graders were typing 25 to 30 words per minute with 95% accuracy which is more than twice as fast as children of that age can actually write.
I found this interesting because I have two school age children. My youngest boy is entering seventh grade and types at lightning speed and knows most if not all the key short cuts to the keyboard. My oldest boy who is going to be a sophomore was tested on his typing skills and typed 125 wpm with no errors.
The Apple study showed the students wrote better and were able to complete units of study more rapidly than their peers. The classroom observers noticed students were taking more responsibility for their own learning and the teachers were working more as mentors and less as presenters of information. Twenty one freshman students from West High School in Columbus, Ohio were chosen at random and stayed with the program until their graduation four years later. All twenty one students graduated, whereas the student body as a whole had a 30% drop out rate. Nineteen of the twenty one students went on to college , only 15% of the students who were not in the study sought higher education. The students in the study routinely and without prompting employed inquiry, collaboration, and technological and problem-solving skills of the kind promoted by the school reform movement.
Both of these studies show the positive impact technology has had on education. Educational technology has demonstrated a significant positive effect on achievement. Positive effects have been found for all major subject areas, in preschool through higher education, and for both regular and special needs students. Evidence suggests that interactive video is especially effective when the skills concepts to be learned have a visual component and when the software incorporates a research-based instructional design. Education technology has been found to have positive effects on student attitudes toward learning and on student self-concept. Students felt more successful in school, were more motivated to learn and have increased self-confidence and self-esteem when using computer based instruction. Introducing technology into the learning environment has been shown to make learning more student-centered, to encourage cooperative learning, and to stimulate increased teacher/student interaction. Positive changes in the learning environment brought about by technology are more evolutionary than revolutionary. These changes occur over a period of years, as teachers become more experienced with technology.
Through my own research and observations I have found the access to information through the use of computers, the Internet, cell phones, GPS, etc. has greatly impacted education. What took volumes of encyclopedias, many hours upon hours of research in library book stacks can be accomplished in a matter of seconds with modern technology. I saw for the first time, my youngest son brought home his algebra book on a CD instead of an actual book. Parents and students can access student assignments and grades on the Internet to get a better handle of what the student is getting done and what areas need to be worked on. Technology is advancing students learning by leaps and bounds. It will be scary and intriguing to see what the future holds.
