SP00LSV.EXE and Its Gang - How to Restore Your Print Spooler's Function?

There are several known malicious programs that camouflage like a legal print spooler subsystem. Nothing can be printed without it if you work under Windows operating system. Printing stops working when you have print spooler service failure. Unfortunately, as a rule spooler subsystem app failure happens in most unsuitable moments.

This subsystem is basically used to manage printing tasks from different applications and users. It's critical for printer spooler subsystem app files to be intact. If you experience problems with printer spooler, first of all check if spoolsv.exe is running. If spooler service not runs, printing is not possible. Trying to run print service may result in failure, if spooler files are corrupted.

The main sign of the printer subsystem crash is an error window, displaying every time you try to print something. Some users even can't add or remove printer drivers when spooler subsystem app service is corrupted. Spoolsu.exe is one of the most famous trojans that cause spooler susbsystem error. Watch if the spoolsv is working, if you have problems with printing. If spoolsv.exe service does not run, it may be the result of spoolsv0.exe malware's activity.

Spoolso.exe is one the issues which is responsible for spooler subsystem errors. Installing printer driver which contains errors or is incompatible with already installed drivers will also cause spool sv service to stop. If you have SP00LSV.EXE virus, check your computer with the most recent anti-virus or anti-spyware or even both. Clear printer's job queue before you try to fix up spooler subsystem problem. Please remember, that not every anti-virus can help you to solve printer spooler malfunction.

Be careful when trying to redeem printer spooler subsystem app failure via printer drivers reinstallation. It is not recommended to trying to relieve printer spooler error manually. If you try to save from spooler subsystem malfunction manually, things may get even worse. Asking a specialist to relieve you printer spooler error would be a more wise idea rather than fixing it by yourself. Reinstalling printer drivers sometimes can also lead to total inoperability of printer spooler subsystem.

Using Spooler Fix Wizard is the fastest and most reliable way to solve printer spooler subsystem app failure. It is guaranteed by moneyback seal that we'll return your money if Spooler Fix Wizard doesn't eliminate your printer spooler error. Relieving spooler subsystem malfunction with Spooler Fix Wizard is as easy as 1...2...3. Just download this Fix Wizard and let it relieve your problem automatically.

Common Business Oriented Language (COBOL) Source Code Generation

COBOL has been around for quite a number of years. Its use and popularity has given way to some of the newer languages. COBOL's utilization is further enhanced by employing sub programming techniques that rely on the Linkage Section of COBOL.

COBOL source code generation is easily accomplished by using a symbolic stream generator with keyword replacements. To accomplish the COBOL source code generation first create an error free COBOL sub program containing the desired COBOL functionality. As an example we would have a COBOL program to operate on fixed length 80 column images. This technique is also known as Physical Sequential File Access. We then highlight various key portions of the COBOL source code so that they may be tokenized and marked for replacement by and intermediate code processor.

Typically the COBOL sub program would accommodate input as well as output thus allowing for one set of code to be used for both input and output of information.

The "RECORD CONTAINS 80 CHARACTERS" clause is changed to read "RECORD CONTAINS <#LRECL> CHARACTERS". The "<#LRECL>" phrase becomes the token and by replacing it with the desired record length of 121 yields a source code program that will operate on logical records with a fixed length of 121 characters.

The FD name of the file description could be tokenized as <#FDNAME> and could be replaced with a desired descriptive name. This process is repeated for as many of the key elements of the COBOL sub program as required that yields the desired code flexibility.

Simply read the skeleton source code into memory and make the necessary replacements of the identified tokens and then save the updated source code to a unique file specification. Afterwards simply compile and link the newly created COBOL source code to yield the newly defined COBOL source code which meets the desired specifications. If the compiler resides on a remote computer simply File Transfer Protocol the source code to the target platform then proceed with the compile and link step. The majority of development is accomplished on the PC and the results are then uploaded to the mainframe for subsequent utilization.

Any processor or environment with the ability or change and replace the identified tokens can be used as the code generator.

Pascal my programming language of choice so much of the code generation work is performed on the windows platform then uploaded to the IBM Mainframe platform. Please keep in mind that I do have access to several PC based COBOL compilers.

Using Graphic Interfaces to Control Unix Operating Systems

The use of the text based command line for running applications or configuring computer systems can be a daunting task. Special commands must be used which may require additional modifiers to invoke the desired computer function. Both Desktop Environments and Windows Mangers provide a graphical method for users to control and configure a Unix operating system, without the need for using text based command line control. Graphical user interfaces eliminate the tedious memorization of text based commands.

Desktop environments are graphic interfaces that provide user control and configuration of a computer operating system in addition to installed applications. The graphic interface generally consist of menus, icons and background desktop images. It also allows users to manipulate items with the drag and drop function or use the point and click function to execute applications on the desktop itself.

The following are Open Source / Free Desktop Environment packages for the Unix operating systems. (Linux, OpenBSD, FreeBSD, NetBSD, and Solaris)

These desktop environments provide users with the ability to utilize software developed with various computer languages, and the ability to utilize the software on different computer hardware configurations.

- KDE is based on the Qt 4 programming language and allows applications to be integrated within the desktop. KDE uses the KWin window manager.
- GNOME is based on the GTK+ programming language and allows applications to be integrated within the desktop. Gnome uses the Metacity window manager.
- XFCE is based on the the GTK+ programming language. Xfce uses the Xfwm window manager.
- LXDE does not have applications integrated into the desktop. LXDE uses the Openbox window manager.

The X window manager is an application that controls the function of the X Window System. It can be configured to manage the visual appearance of display windows and control panels. The X window manager also controls how users interact with these graphical interfaces.

The X Window System provides the system resources and software components necessary for the creation of graphical user interfaces (Windows Managers and Desktop Environments).

The following are the most common Open Source / Free Window Manager packages for the Unix operating systems : Linux, OpenBSD, FreeBSD, NetBSD, and Solaris.

These windows managers provide users with the ability to utilize the software on different computer hardware configurations and provide various visual appearance.

- Blackbox is written in C++. It offers support for multiple workspaces.
- Fluxbox is based on Blackbox 0.61.1. It offers minimal support for graphical icons.
- Openbox was originally based on Blackbox 0.65.0. It allows users to utilize applications without a full desktop environment installed.
- Enlightenment can be used as a substitute for a complete desktop environment.
- IceWM was written in C++. It can be configured to recreate the visual appearance of various desktop environments.
- Window Maker provides drag and drop user control in addition to supporting multiple workspaces.
- Sawfish is written with a scripting language that is similar to Lisp. It provides very basic features.
- Metacity is written in GTK+. It was created for use with the Gnome Desktop Environment.
- MWM is based on the Motif toolkit. It does not support desktop icons or multiple workspaces.
- FVWM is based on TWM. It provides the ability to display a 3D visualization ( similar to MWM ) and supports basic multiple workspace.
- AfterStep was originally based on FVWM and was designed to provide a NextStep themed appearance.
- CTWM is based on TWM. It provides rudimentary GNOME desktop support and multiple workspaces.

Text based command line configuration and control can provide a comprehensive method for daily computer management and operation. Unfortunately, users are required to know the necessary unique commands and their unique structure that must be used. Graphical user interfaces alleviate that requirement and make the use of a computer both simple and effective.

The History of the Modern Day Camcorder

The use of video camera started as television cameras.The original ones were large and heavy and very expensive.They were only television broadcast studios. As technology grew, the size of the camera shrunk until they became portable size.

The first video recorders were actually two machines.One machine was the camera that took the pictures and then there was a VCR that had to be attached to record and replay the images.The VCR units were usually attached to a television viewing unit.

Even though the size of the camera has diminished, there was a lot of equipment still involved. These new units still were a giant step of technology even if it took two people to operate them. In the case of television, the recordings were ready to go instantly rather than waiting for the development of film. There were now detachable video cassettes.

There were some major events that occurred in 1982 that made the camcorder more available for home use. First JVC introduced the VHS-C format. The second was that Sony released the first professional camcorder named Betacam. The new VHS-C tapes were small cassettes that were being used in VCR's. The Betacam allowed for more professional grade video recording. Now there did not need to be two units, the recording could be done in the camera and the portable Camcorder was born.

By 1983 both companies were competing and making the units easier to use and added more bells and whistles. Now you could record from 40 to 120 on one cassette that could be played on and VCR.

The Beta or 8mm and the VHS models both have advantages and disadvantages. The greatest problem with betamax and what eventually ended the completion was that it could not be played on the common VCR.

Eventually in the 1990's the camcorder was transformed once more and became part of the digital era. Now instead of tape based cassette, the DV and miniDV were introduced. This leap made the recording media smaller and the quality of recording better. Recording could not be done on small disks and DVD's and to even smaller compact disks.

Even with the improvement of the camcorders, the price of them actually dropped. The original heavy units were priced around $1500 and now a palm sized unit costs about $100. The size keeps shrinking and now many cell phones have video capturing abilities that a light years beyond the first tape models.

Co-Location and the Benefits

Co-location most commonly refers to running or installing data into a single computer, data centre or process. For example, virtualisation happens when a host server uses virtual software and hardware platforms to run more than a single instance of a piece of software on a different platform. When it comes to website hosting, co-location involves co-locating the network equipment that keeps your website up to another location. There are a number of facilities that exist specifically for the co-location of equipment. The gear may be co-located to a brand new location, but the end result is essentially the same and does not necessarily impact your website's capabilities.

The biggest decision to make when it comes to your hosting is whether or not you should go for data centre hosting or co-location, however they are actually one and the same for the most part. Co-location facilities are data centres, but not all data centres are co-location facilities. Some data centres may not allow for any equipment to be co-located, but may still allow for purchase of dedicated servers so that essentially the same thing can be achieved. Data centres are brick and mortar facilities; equipment is housed that allows for remote user access for web hosting and other computer related services. Co-location is the process of housing this data and information someplace else other than in these data centres owned by the hosting company in question.

Some of the benefits of co-location are listed below:


One benefit to co-location is an increase in security, as data centres offer strong server security and confidence for your most critical data. Data centres used in co-location are monitored all the time, 24 hours a day and 7 days a week which means that your data is safe.
Your web host benefits from co-location because they do not have to shell out the costs associated with building and maintaining their own in house dedicated servers, therefore they can sell hosting to you and co-locate your hosting equipment to a more inexpensive option.
Co-location allows hosting clients to have their own bandwidth, ram and other important hardware without being forced to share. What this means is that systems and servers can run at their highest possible capacity.
Because co-location involves dedicated servers that are regularly monitored and located in the highest quality facilities, hosting clients can rest assure that the services they purchase will be 100% reliable and trustworthy.
The concept at the core of co-location is location independence, which means that you are not required to have your data or equipment hosted by a specific data centre. Instead, you have independence to host your data and equipment wherever it is most feasible for the smooth operation of your business website or data. By co-locating your server, your physical business can run efficiently and effectively.
Another benefit of co-location is an increase in flexibility because you will be able to grow and upgrade your technology as your company grows without ever having to make additional investments.

Data Storage Green Initiatives Take a Knock

Data centres and the data storage industry have received a lot of attention recently. There is increasing concern over the amount of energy that data centres consume, as well as concern over the ability of storage devices to develop quickly enough to keep up with user demands. In a 2007 study by the Environmental Protection Agency (EPA) on electricity usage by data centres, it was shown that the cost of data storage is steadily rising, while the budgets for networking equipment and servers remained relatively steady. According to Steve Denegri, a storage consultant and financial analyst, this trend is bad news for data centres.

Denegri contends that the direction in which many data centres are heading - towards increased energy efficiency - is not the correct one, and will ultimately lead to a deepening of the storage crisis. He says that in order for the storage industry to grow, and to keep up with the demands placed in it by consumers, it needs "an ample supply of energy". The fact that the industry is trying to work around energy limitations with green initiatives rather than addressing the problem directly places undue stress on the industry and consistently ignores real consumer needs.

Denegri says that the storage industry is trying to enable consumers to use more resources at lower levels of power consumption because that it what they believe consumers want. But Denegri contends that what consumers really want is lower utility costs. By pandering to the green trend and projecting an environmentally conscious image, the storage industry is in fact placing consumers between that much talked about rock and hard place. As companies continue to make small adjustments and adaptations to their energy efficient devices, consumers have to continually upgrade or replace their systems. So while storage companies are assured of a continuing market, consumers are paying through the nose for better "low cost" performance.

Instead of going green, the storage industry should tackle the energy problem head on, which according to Denegri, entails building "multiple thousand-megawatt" power plants, as suggested by the Uptime Institute. Companies need to expand and contribute to the capacity of power grids, rather than being a drain on them.

While Denegri allows that energy efficiency is an important concern, he's somewhat scornful of companies that "buy into that nonsense". As far as he is concerned, the storage/energy problem should be viewed from a strictly business position and that purely business orientated solutions should be applied. If it doesn't increase revenue and pander to the whims of consumerist public, then it's not worth considering.

Even though his solutions make great business sense, Denegri has failed to take into account the fact that it is precisely this kind of thinking that led to this problem in the first place. All industries need to start taking cognisance and responsibility for their impact on the environment, and rather than behaving like spoilt children denied their favourite treat, they should find ways to earn their treats. Consumers will also have to learn to live more simply and economically because this is not purely a business problem, but an overarching environmental one. Companies who subscribe to this way of thinking are not "buy in to any nonsense", but are demonstrating appreciable common sense. Their efforts shouldn't be mocked, but applauded.

Addicted to Laptops and Other Forms of Digital Communication

Holidays are supposed to represent time off from routine day-to-day living. Going away for a holiday used to indicate a willingness to sever all ties with the workday life, including daily telephone calls from random friends and family. Holidays were a complete break designed to allow tired, stressed and over-worked employees time to recharge, unwind and relax before heading back to the hurly-burly pace of the work place. But wireless digital communication devices have put an end to all of that. These days' people are accessible no matter where they are or what they're doing. People panic if they find that they've left their mobile phones at home, because heaven forbid they miss a call or a text message. Whereas being out of contact used to be the ideal, it's now considered a nightmare.

According to a recent poll by AP-Ipsos, one in five people couldn't bear to be separated from their laptops during their last holiday and 80% of holiday-makers couldn't part with their cell phones. To be fair, not all of those who took their laptops and phones with them on holiday used them for work purposes. Many (50%) simply checked their personal emails and voice mail to stay in the social loop. But 19% of people polled said that they worked on their holiday, 20% said that they checked work related voice mail messages, 15% said that they called in to see how things were going and around 40% said that they checked their work emails.

Not surprisingly more young people (younger than 40) hauled their digital baggage with them. 15% of those aged 50 - 64 took their digital devices with them, compared to 25% of under-40s. People under 40 were more likely to check personal messages, while those who checked work related messages tended to be slightly older. Of those who are digitally addicted, white men are the biggest culprits, as were those with high levels of education and high salary rates, which probably reflects the degree of responsibility or obligation felt by these individuals.

Geoffrey Godbey, professor of leisure studies at Penn State University, Pennsylvania, says that men in their late 40s and early 50s tend to be middle managers and feel that they simply can't afford to be out of the corporate loop. They feel that in today's' competitive business world a holiday is a luxury that they can ill afford. Although some genuinely love what they do, so staying involved is no hardship. The key question is whether people work on holiday because they really want to or because they feel they are obligated to.

While all of this is very alarming, especially for those who don't work on their holidays (and may now feel pressured to do so), the most frightening statistic from the poll revealed that only 7 in 10 women and 5 in 10 men read a book while on holiday. The fact that literature is taking second place to electronics should be of far greater concern to the masses than the psychoses of workaholics.
