Hardware Keylogger – Helping You To Monitor PC Users Without Being Detected

Sue has been the most commited employee. She is always at her duty post doing what she was being paid to do. With all the zeal and industry being exhibited by Sue and most of her colleagues, the company couldn’t explain why productivity was taking a steady and speedy decline until a consultant detective was hired.

Investigations revealed that Sue spends 70{9f36af22880a9321975b786c158ed5857ccebcf076e7d8e0e66c9e957c871baf} of her -work’ sessions in dating chat rooms. Other times, she was emailing her pals and reading internet news – oh she loved the -fashion and style’ segments!

Worse case for Steve who was discovered to be trading the company’s sensitive information’s to a rival group.

How were these discoveries made since these people work alone in their closets and never share their computers?

Hardware keyloggers to the rescue!

keylogger are devices that are used to monitor the activities on a computer. It works by tracking the keystrokes, recording conversations, tracking the creation of documents and monitoring emails. This is usually achieved when a hardware circuit is attached somewhere in between the computer keyboard and the computer. They are designed in such a way that they blend with the rest of the computer cabling.

How they work

They basically interrupt the keystrokes signals and stores them away. The storage can range from 2MB, which is enough for one – week use, and up to 2GB of flash memory. Ideally, these memories can only be accessed by the individual that installed the device.

To access these memories the installer presses a combination of keys which switches the device from a keystroke-capturing mode to a usb flashdrive mode. Then you receive a message which tells you that a new usb disc drive has been located, and there you will find the keystroke logs that were collected. You also see a configuration file which you can modify in order to change the secret access key.

Hardware Keylogger are now preferred to software keyloggers. The latter can be easily detected by software scanners, and their operations are limited to a single computer. They are also dedicated to only one type of operating system which could be Windows, Mac OS, Linux, etc unlike the hardware equivalents which are operating system – independent, and whose operations, recording and playback, can be done on two different computers. One other minus for the software type is that it requires full access to the operating system to be installed, when the installer might only want to sneak it up and catch the target users off guard.

So for parents who want to track their child’s PC activities or employers who want to monitor their workers or generally for computer users who want to back up typed texts, monitor remote computers, retrieve unknown passwords without depending on the operating system, hardware keyloggers provide the perfect answer.

As we are facing certain uncertain times, it is hard to predict whether we will be able to stop making cuts to school programs and their benefits. Using the science experiment kits, children will be kept interested and focused in the classroom.

Robots Gain Ground In Demolition Projects

Some science fiction writers envisioned a world overrun with robots by now. Well, thats hardly the case, unless youre talking about specialized areas of industry, including robots that have helped with the safety and overall effectiveness in demolition projects.

For more than three decades, robotic equipment increasingly has been used in demolition and construction projects around the globe. There has been no need for a man vs. machine contest of superiority. Nor has there been fear of a robot rampage as in the science fiction film, I, Robot. Rather, people and machines work together as humans operate remote controlled machines in cutting, breaking, crushing and other demolition tasks.

While the popular image of demolition is the implosion of buildings with explosives, this is hardly what happens in the vast majority of all demolition projects. The National Demolition Association reports implosions account for less than 1 percent of all demolition work.

Demolition mostly involves the step-by-step destruction of an entire building or partial structure in often hazardous conditions, whether the wrecking ball or robotic demolition equipment is used.

Demolition practices today are not only quicker but safer and more cost-effective, according to the National Demolition Association, which represents more than 1,000 U.S. and Canadian companies that offer standard demolition services as well as a full range of demolition-related services and products.

In 2008, BBC reporter Steven McKenzie explained how a small army of robots was deployed in the clean-up of a Scottish nuclear complex. He said like WALL-E, the star of the Pixar animated film set in a waste-covered Earth of the future, the machines in Scotland were tackling manmade waste.

The real-life robots have been working in highly radioactive areas of Dounreay in Caithness in the Highlands, he said.

A spokesperson for the project said: “Using remote tools such as the Brokk 180 can complete some physical decommissioning tasks more quickly than human workers, and without exposing them to the hazards. The Brokk was used in smashing down walls. For a person to do that they would have to wear an airline suit and a sledge hammer.”

Benefits of using robotic demolition machines include:

Remote Controlled: Safer to operate
Electric Power: No Fumes
Compact Size: Accessibility to tight spaces
Light weight: Easy on floors
Multiple tools: Always jobs for machines

In June of 2009, Construction News Portal reported R. Baker & Son All Industrial Services Inc., a specialized demolition contractor, completed an eight-phase, highly technical, demolition and environmental remediation project at Kings County Hospital located in Brooklyn, N.Y.

Demolition crews utilized various hand tools to accomplish the demolition as well as specialized demolition equipment which included skid steers with demolition hammer and bucket attachments and Brokk 90 hydraulic breakers, Construction News Portal said.

The Four Main Causes Of A Slow Computer

When someone buys a new computer or reimages a hard drive, one thing that usually impresses them is the speed of their system. The computer wakes up quickly, and Web pages display almost instantly. Over time, though, computers often slow down. Here are the four main reasons why:

Too many programs: It’s not unusual for a person to have dozens of programs installed on their computer. While many people think they only consume system resources while they are actually running, this isn’t the case. Every program takes up some of the computer’s memory. If your computer takes forever to start up and runs slowly, you may simply have too many programs installed.

Not enough memory: RAM, or random access memory, is what allows the computer to perform tasks like opening documents, accessing Web pages, and loading programs. All programs consume RAM, and if you run out, your computer will be extremely sluggish.

Malware: This is a broad term used to describe viruses, spyware, and adware. All types of malware can slow down your computer, and it’s a very common reason why computers don’t perform like they did when they were new.

Registry errors: Your computer executes tasks by accessing files stored in the Windows registry. Over time, these files can get moved or split apart. Your computer still needs them, though, and takes longer to find them. This has the effect of slowing down your entire system.

The good news is that these problems can be fixed relatively easily. Deleting programs you don’t use, running a registry repair program, and investing in quality anti-virus and anti-spyware software are all ways to speed up your system. If your computer is very old, it may simply not have the RAM to handle everything, so you might need to upgrade your desktop or add some memory to increase speed.

Use Computer Training Directories to Easily Locate What You Need

If you are looking to receive some sort of computer training, there is little doubt that you feel overwhelmed when searching online to find the training you need. As the internet technology world continues to expand, grow and change with the times, more and more training is required and thus being offered by an increasing number of companies.

The easiest way to find exactly the training you need is to make use of a computer training directory. If you happen to live in the United States there are directories set up that only require that you click on your state to locate local computer training courses designed to help you improve your career. Once you have clicked on your state, you will then be presented with a list of the major cities within the state who offer training courses. If you live outside of the U.S. you can use a directory that asks you to simply type in your location-it will give you a list of results that shows you companies who offer training courses near you.

More and more IT professionals are opting to take online training as it offers them the flexibility to continue working as they learn new skills. Online computer training has become so popular in fact that you can also find great directories that will list the top companies and schools who offer web-based learning.

The IT world is one that is in a constant state of transformation and one in which more complex technologies are constantly being upgraded and improved upon. In order to keep yourself highly desirable to prospective employers and clients it is absolutely imperative that you continuously hone your skills and take the training and certification exams that you need to stay ahead of the competition. Nearly every large corporation on earth today consists of a full internet technology staff of highly training professionals who are in place to ensure that the company’s computer network remains working smoothly twenty-four hours a day. If you would like to become a part of a large corporation in the IT support arena then you must possess the skills and certification that is in demand.

A computer training directory is the first step you should take to find the training you need. These directories are in existence solely to assist people just like you who are striving to compete and who are looking for very specific training courses.

Evolution Of Computer Technology

Today computers are an indispensable part of the lives of human beings but at one point of time there were no computers. Knowing the history of computers and how much progress has been made can aid us in understanding just how complicated the invention of the computer really is. Unlike other devices, the computer is the one invention that does not have any one specific inventor. Throughout the development of the computer, various people have made contributions to making a computer work. Some of these inventions were those of complete computers or other additions that helped revolutionize the computer that existed at that time. One such invention was the Integrated Circuit.

The single most important year in the history of computers is 1936. It was in 1936 that the very first computer was created by Konrad Zuse who called it the Z1 Computer. This was the first system that was fully programmable. Even though there had been devices that had come and gone before this but they didnt match upto it because of its superior computing power. Till 1942 no business saw profits and opportunities in computers. The first computer company was called ABC computers and was owned and operated by Clifford Berry and John Atanasoff. Two years later in 1942 came the Harvard Mark I computer which furthered the science of computing even more.

The age of computers saw its biggest change ever in 1953 with the introduction of International Business Machines known today as IBM. The company has always been a key player in the development of new systems. This was the first real competition to bee seen in the world of computing and helped to encourage faster development of better computers. The first contribution of IBM was the IBM 701 EDPM Computer. A year after this the first high level programming language was brought to the centre stage. This was a programming language that had not been written in ‘assembly’ or binary languages and was called FORTRAN which was written to enable more people to be able to program computers. In the year 1955 Bank of America, Stanford Research Institute and General Electric joined hands to introduce the very first computer for use in banks.

After that the evolution was quick. Computers like Apple I and II, The Scelbi, Mark-8 Altair, TRS-80, the Commodore Pet computers and IBM 5100 were the leaders of the sector of home computing. The micro processor was like the heart of the computer and began with the Intel 4004. from then it has evolved into todays Pentium IV, Dual core and Core 2 Duo processors. Along with the evolution in Hardware came the evolution in software which went from assembly languages to todays languages like C++, Java and PHP. There is more to come in this field and that more will surely be AI or Artificial Intelligence. The term was coined by John McCarthy and is today a major field of study.

Embedded C Programming Compilers For 8051 Microcontroller

Todays sophisticated computers are developed as embedded systems so that they can be complimentarily used in mobile devices and electronic appliances. The microcontroller turns out to be the key element in an embedded system. Actually a microcontroller is a microprocessor giving more emphasis on the input & output operations. It controls the operation of electronic devices by giving them access to communication, measurements and switching information. Thus a microcontroller is regarded as a device controller. Intels 8051 microcontroller is among the oldest members of the microcontroller family, yet is very popular among users. Technical analysts attribute its popularity to its amazing architecture. Some of the reputed computer manufacturers like NXP, Silicon Labs & Atmel are still using 8051 microcontroller as the basis of their microcontrollers.

The 8051 microcontroller has a complicated memory structure that requires special software instructions to access it segment wise. Therefore special kind of compliers needs to be designed to make the memory accessible. Since the 8051 microcontroller is widely used in IT industry & many projects as well, companies have created their own 8051 microcontroller compatible compilers. As a result various kinds of embedded C programming compilers for 8051 microcontrollers are available in the market. Most of them are offered as part of a package along with debugger, simulator & integrated development environment (IDE). The Keil IDE/compiler is one such popular variety. Similarly SDCC (Small Device C Compiler) is a free & popular compiler that is found compatible with Zilog Z80, Motorola 68HC08, Maxim 80DS390 & Intel 8051 microcontrollers. The open source software code of SDCC is distributed under the guidelines of GNU General Public License.

Though pascal language is rarely used in embedded C programming, a few special Pascal compliers are available for the 8051 microcontroller. The Turbo51 & KSC Pascal51 are good examples of commercial Pascal compilers. Turbo51 is a free complier based on fast single pass & advanced multi-pass optimizing technology & using syntax of Borland Turbo Pascal 7.

While there are not enough options in basic or Pascal compilers, the C compilers are available in abundance. Users are facing difficulty in finding good quality basic or Pascal compilers for 8051 programming. The chief function of the compilers is the code they produce which should be optimized well to enhance the speed & size. However it is not the programming language in compilers which decide the size of the program codes for achieving specific tasks in 8051 programming. Either Pascal or C can be used to generate an optimized & compact code. It is the programmers preference on which platform he/she will feel comfortable working in.

Error 1201 In Information Store Using Exchange Server

Exchange Server follows transaction logging system. Information Store folder is comprised of related transaction logs along with storage groups. It means that Information Store is the most critical part of Exchange Server. Number of storage groups may vary according to the requirements of organizations and Exchange Server version being used. If the Information Store suffers inconsistencies or corruption, EDB Recovery will recover lost data in the absence of online backup.

Priv.edb and Pub.edb are two critical files of Exchange Server Storage Group. These files contain user mailboxes. If these files get corrupt, Exchange Server may return 4294966095 error and Information Store service may fail to start. The corresponding event entry in Event Viewer is -1201.

Apart from EDB corruption, -1201 Event ID may also generate if log files and EDB files are on different drives and due to some issues, log files are not available. To resolve the issue, user can follow these steps:

If online data backup is available, user can restore Information Store from it
If Information Store backup is unavailable or incomplete, user needs to use Eseutil repair utility to perform Hard Recovery. The process requires two basic considerations: backing up Mdbdata folder to avoid further data loss and ensuring that hard disk contains sufficient free space for Hard Recovery. Mdbdata folder contains all log files and storage groups of Exchange Server. However Exchange Server Repair requires following commands to be applied:

eseutil /p /ispriv /tx:tempdfg.edb
eseutil /d /ispriv /tx:tempdfg.edb
isinteg -fix -priv -test alltests
eseutil /p /ispub /tx:tempdfg.edb
eseutil /d /ispub /tx:tempdfg.edb
isinteg -fix -pub -test alltests
If problem persists, third party Exchange Server Recovery applications can be used on Mdbdata folder to repair damaged EDB files. These are the tools that can scan and repair damaged EDB files and extract user mailboxes without affecting data integrity.

Stellar Phoenix Mailbox Exchange Recovery is the most powerful edb recovery software. It extracts user mailboxes from damaged EDB files and restores them as individual PST files which can be used with Outlook. It supports Exchange Server 2003, 2000 and 5.5. It is compatible with Windows XP, 2003 and 2000.
Exchange Server 5.5
where x: is the drive containing the required free disk space.

NOTE: When the Information Store service has started, after the repair process, make a full online backup immediately.
