Point of sale systems are revolutionizing the retail and hospitality industry. They have gained much attention and are now much more common then the older cash register terminal systems that once used to be at every retail store in Australia. The reason for their increasing popularity in retail stores, hotels, and restaurants is that they are more efficient and make processing and tracking orders easier.

Whether it’s a Brisbane point of sale, Sydney point of sale, Melbourne point of sale, or a hospitality point of sale in Adelaide a point of sale helps to speed up the service and delivery of good to customers. While a cash register only stores money and is often attached to a computer or bar code scanner a point of sale or POS does this all in one interface. Cash registers are often slower, and more limited in their options and methods of payment then a POS. For these reasons, many cash registers systems are being dropped for the more modern POS systems.

In the hospitality industry a POS system is much better because of the different needs, requests, and reservations of customers. Data must also be stored, and processed by the staff of the hotel to ensure smooth operation of the hotel. Because POS systems can record date such as payroll. labor, volume of good sold etc, they are more feasible then a cash register system. Data in our age is a vital and valuable resource that can make or break a company or business. In the hospitality field, this date recorded by POS systems can be used to track what customers need, are lacking, or is profitable and what is not. Furthermore POS systems can be connected to networks, and other third parties. This can possibly set up lucrative affiliates, advertising opportunities aimed at certain demographics and hotel clientele.

POS systems are now found in high volume restaurants. Restaurants that bustling with clients have installed this new software to be able to track and complete orders in real time, similar to a rail or airport flight schedule. Customers appreciate when their food is delivered on time, and when their orders are not mixed up. For a restaurant this could mean greater customer retention, and more satisfied clients. Then end result of the POS system for a restaurant would be a greater profit margin, happier clients, and less idling. For high volume or busy restaurants the POS system offers incredible advantages and the possibility of increasing profits.

Many retail, hotels, and restaurants have switched to point of sale systems for efficiency, reduction of order processing, date tracking, convenience, and network links. The next time you see a pos system in your local city or town think of the benefits it offers to customers and business owners. Happy shopping!

One thing many webmasters don’t do (which baffles me) is not getting their private and secure web development environment to test their sites in order to prevent catastrophes.

This lesson I learned the hard way.

Every time a major update from a software gets released, you should always install it first in your cloned website, just to be sure it won’t “break” the official website. The last thing you’ll want is spending several hours in front of your pc looking for tech support.

I’ve personally sacrificed many Sundays that way, when I should be socializing. I bet you don’t want that.

Some of you might me wondering “Well, I’m not willing to sacrifice my precious Sundays, that’s why my hosting company has tech support. So they can do all that boring stuff for me”.

Unfortunately, tech support sometimes can be slow to solve your issues and if you have some website making you money, then you need to make sure nothing bad happens to him.

Imagine if you pay a ton of money to get traffic to your website, and when you visitors find it, all they see is an error page. You can bet most of them won’t return and you won’t get a refund from the advertisers.

By having a clone of your website in your hard drive, you will save a lot of headaches and money in some cases. It’s really easy to setup a private web environment.

In order to that, you’ll need to download the appropriate software. For the Windows platform it’s called WAMP (Windows, Apache, MySQL and PHP), for Mac It’s MAMP and for Linux it’s LAMP.

I’m not telling how to install to run the program. Installation is really easy and there is plenty of documentation that explains how the program works. If you still have questions, I recommend you to watch some video tutorials on Youtube.

That’s how I learned to mess with WAMP.

Okidata C6000 Color Laser Printer

Overview

The Okidata C6000 is what can be best described as a perfectly balanced printer. It does a superb job of offering the consumer a great balance between everything that workgroup printer purchasers are looking for in a color laser printer. It is priced in the middle of the road for these types of network printers, but provides the high quality printing capability of a much more expensive printer.

Features and Functionality

Whenever you’re purchasing a network printer, the pricing of the unit is something that you’re always going to be worried about. Priced in the $700 range, this printer is one that most people that are looking to purchase a printer large enough to serve their entire office are going to be able to afford. However, its real savings come in the form of its overall cost of ownership. Because the Okidata C6000 cartridges are long lasting and affordable as well, they help ensure that the actual cost per page of printing on this unit is lower than the competition. The statistics on the printer are listed at 2.2 cents per page for black and white printing, and 13.8 cents for color printing.

Instead of relying on older technology which requires a document to make four passes (one for each color) through the printer, the Okidata C6000 cartridges all apply their color to the document at the exact same time. They do this by a single pass process that applies the color from the Okidata C6000 cartridges through a series of LED print heads. This produces a great quality of color, and also allows the printer to print much faster than similar models that use a four pass system.

In the case of the Okidata C6000 cartridges, those speeds are typically going to be very impressive. The monochrome print jobs are measured at a speed of 24 pages per minute. Even when printing in full color the computer can print at 20 pages per minute, which is extremely fast for full color.

The printer has a base paper capacity of 400 pages. It is able to be expanded in certain ways, most notably with the addition of a duplex unit.

Conclusion

As mentioned at the beginning of the review, this printer is sure to satisfy you in almost every regard that you may evaluate a printer by. It is affordable, fast, and prints at an exceptionally high quality. Although it wasn’t mentioned earlier, this printer is also flexible, and gives you options for printing on various types of documents. This, in combination with the prices that the printer offers, can help to greatly reduce your printing costs by limiting how often you have to request third party printing.

Formatting business documents to a single versatile code is no more a choice! It is a necessity without which smooth business operations and data management remain evasive goals. Today, corporate entrepreneurs of every segment – small, medium scale and large, are targeting effective PSD to XHTML conversion depending upon their needs. File and data management can become rather cumbersome to maintain if they are not accessible in a widely preferred and accepted format. Without a doubt HTML is the global choice today.

Essentials you need to know

To convert data into the desired format, you need to first and foremost sort your unprocessed or ‘raw’ files. These could be in any format – scanned books, DVD, printed data or even CD.

The volume and quality of data then needs to be addressed and properly evaluated prior to taking on the actual conversion. Conversions being commonly addressed today include:

? PSD to HTML

? PSD to CSS

? Conversions from any other format to table-less HTML, XHTML slicing, table-less XHTML

These are just a few to mention. To convert PSD to HTML you have the choice of either delegating the job to a professional data and document conversion establishment or handling it in house.

If outsourcing is ‘out’ for you, then you should know that the conversion can be handled in-house too and rather effectively. However when addressing versatile reformatting of PSD to XHTML coding or trying to convert PSD to CSS or convert PSD to XHTML you need to be adept with the language and armed with the right know-how.

Addressing conversion

You can achieve commendable results in terms of efficiency in saved time and accuracy as far as this conversion is concerned. There are many professionals out there who make available for highly nominal fees (that are also negotiable) value added conversion services to make back office work easier.

They work via long and short term business agreements and offer ongoing support in data management and procuring sensitive data 24×7.

PSD to XHTML or PSD to CSS is easily achieved by a web developer. He is able to professionally address the conversions of web pages from the Adobe Photoshop document format or PSD format into any other desired one.

The initial formatting created by the web designer also includes multiple design instances. These Photoshop Layer Comps are ingrained management tools that actually help the web developer in achieving the desired change. This is done by step-by-step guidance that the developer assesses through commands.

Converting from psd to html is a page by page transition wherein the data or page design is converted into the desired format and code. However, it is not uncommon to find yourself facing a situation where the in house staff is either hesitant or the need to employ a fresher to handle the job.

The outsourcing companies that handle the conversion you seek do so from their own offices, so you are saved of an extra hand. The conversions are safe and easy provided they are addressed with reasoning and understanding that comes from professional training and experience.

Deleted files can have sensitive information. Some applications also lead to the deletion of files needed for running other programs on your computer. Data recovery becomes a serious task in such cases. First step is to see if the data is still present in the Recycle Bin.

If the files have been deleted from the Bin as well, you need to use a specialized software tool to recover them. Many people wonder how we can recover files that have been erased from the Recycle Bin. When files are erased on your computer, only addresses of those files are trashed. There will be no links pointing to those memory addresses. The space is occupied when you copy new files to your computer. Be careful not to copy anything until recovery software has done its job. There are plenty of free software tools available.

If your files are there in Bin, restoring them to the desired location is pretty easy. If you know the name of the file to be recovered, you can easily find it in the Recycle bin. Double click on the Bin icon on desktop and browse through the files. Change the type of view in Bin to easily locate images and video files. You can see the thumbnail view of files that way. You can also see the file size and other important details using thumbnail view.

Sort the files in a desired order of date, location or size. Browsing through Recycle Bin is same as browsing through any other explorer window.

You will have to use search function to locate the files to be recovered if your Bin has too many. You can search the file by its complete name; file extension or part of name. Choose the ‘restore file’ option after right clicking on the selected file. Data recovery tools can be used if the files have been deleted from the Recycle Bin. These tools work like System Restore feature on your computer.

Datacenter cooling is the main concern for many datacenter managers. Excess heat in a server room adversely affects equipment performance, shortens its lifespan, and leads to a premature end of life for equipment. Keeping a server room at the recommended 68 ° to 77 ° F (1) is not an easy task. There are many factors that make cooling today’s datacenters a significant challenge, including high-density computing clusters and rapid changes in technology.

High-Density Computing Clusters

The rise in the use of blade servers and virtual servers has greatly increased the potential amount of power consumed per rack, as well as the resulting heat output. While the heat dissipated by a 2 ft by 2.5 ft rack is currently about 10 kilowatts or more, experts estimate that designs for future equipment will require dissipations of 30-50 kW in the same rack space.(2) The trend toward increased power consumption has been documented in several studies, including one recent five-year study of 19 computer rooms that showed that power consumption rose by 39% from 1999-2005.(3)

Changes in Technology

Traditionally, advances in technology have occurred at an extremely rapid rate, as illustrated by “Moore’s Law,” which predicts the doubling of semiconductor performance approximately every 24 months. Historically, increased computational abilities have led to increased power consumption and heat loads. Datacenter managers should take these trends into account when planning for future expansion. According to Gartner Research, “Without careful planning and coordination between the data center facilities staff and the server procurement staff, data centers will not be able to increase power or cooling in line with increases in server deployments…through year-end 2008, heat and cooling requirements for servers will prevent 90 percent of enterprise data centers from achieving the maximum theoretical server density.” (4)

Isolating Hot Spots

Hot Spots are areas in a datacenter that are not properly cooled, often resulting in temperatures that exceed recommend conditions for maximum equipment reliability and performance. Hot spots are not necessarily caused by a lack of cooling capacity and commonly occur in datacenters with sufficient or excess cooling capacity, but can be caused by poor circulation or improper air flow.

Zone Hot Spots can be present over fairly large areas in a datacenter and occur when the temperature at all air intake levels of a rack or cabinet are too hot, due to expelled air flow that is not properly routed.

Vertical Hot Spots occur over a small area and often affect a single server rack. They occur when equipment at the bottom of a rack consumes the available supply of cold air and devices higher up in the rack pull in the hot air exhaust of adjacent equipment or ambient air.

Strategies to Improve Datacenter Cooling

Datacenter managers can take several steps to meet datacenter cooling challenges, including choosing the right rack, increasing datacenter energy efficiency, using liquid cooling units, and taking advantage of environmental monitoring.

1. Select The Right Rack And Accessories

To fully maximize equipment cooling, when selecting a server rack consider intelligent and space-efficient design features that various rack models offer, including frame profile and capacity for increased packing density. Use blanking panels to manage air flow efficiency and select a rack with built-in channels for better cable management and improved air flow. Fully perforated doors and top panels can help improve ventilation as well. Also consider server rack accessories that will improve cooling, including fans, enclosure blowers, and rack air conditioners. In addition, consider using energy-efficient power supplies, such as 220V power, which significantly increases available amperage into the server rack, using fewer circuits while providing a more balanced power load. This can reduce the overall number of PDUs needed to power equipment, leaving more space for airflow.

2. Aim for Energy Efficiency

There are several steps you can take to reduce overall energy consumption and resulting heat loads in your data center. To begin with, consider hiring an expert to conduct room diagnostics, measure airflow, and correct any cooling problems identified. Next, conduct a thorough audit of your equipment and determine if any servers can be consolidated or discarded–this process can cut power consumption in some organizations by up to 30%. (5) Finally, clean up any clutter under your datacenter floor, including cabling, that might be impeding air flow.

3. Deploy Liquid Cooling Units

As power-intensive applications and server densities have increased, Liquid Cooling Packages (LCPs) have become a valuable alternative to ambient air cooling and can better meet the cooling challenges presented by high-density computing clusters. These modular, temperature-neutral high-density cooling solutions utilize air/water heat exchangers to provide uniform, effective cooling. Liquid cooling units use a special horizontal airflow with constant-temperature cold air provided at the front intake and hot air removed from the rear of the enclosure. They can be mounted at the rack base, in a rack “side car.” Fully-loaded LCPs have a 30kW cooling output with three cooling modules possible per equipment rack, and controlled variable speed fan and water flow based on actual heat load generated in a cabinet.

4. Use Environmental Monitoring

These devices allow administrators to proactively monitor rack and server room temperature, including hot spots, at any time and from anywhere and provide protection to mission-critical applications. They also allow administrators to continuously monitor amperage draw per circuit, water leaks, and physical security and can send alerts automatically via SMTP/SMS/SNMP when conditions exceed established thresholds. This allows IT managers to quickly respond to any irregularities before they become larger problems. Environmental monitoring devices also help administrators in future planning, as they provide valuable data that can be used for trending analysis.

When considering datacenter management, cooling is only one piece of the puzzle. Other key considerations include intelligent power management and KVM console management tools.

The problem of a slow system is as old as computers… but fixing this issue can be extremely difficult, even for the most experienced of computer technicians. Fortunately, modern advances in software development have made it possible for almost anyone to fix their slow computer and here’s how…

The way to fix a slow PC is to fix the problems that cause it to run slow. This can be done in several ways, but the single most important factor in how fast a computer will run is its ability to read the files & settings that it needs. Every time you use your PC, it needs to read 100’s of files and settings just to help it recall all the different details that you have on your system.

The biggest problem with slow computers is that they cannot read all the details you have stored, which makes them take longer to process them, which makes your computer seem to run slower. The higher the number of damaged & unreadable files, the slower your PC will run and the more frustrated you will get. Have you ever wondered why new computers run so fast? It’s because they don’t have any damaged files or settings to slow them down. Fixing all the damaged settings on your PC will boost its speed dramatically, and here’s how to do it…

There are two factors which make most PCs run slow. The first is a part of Windows called the ‘registry’. This is a database which stores information and settings for your computer, and is where everything from your login details to your screen resolution are stored. The registry is a highly important part of Windows because it’s constantly being opened and read to help it remember all of your details. Unfortunately, the database is prone to becoming damaged, which leads to Windows taking longer & longer to process it, slowing it down.

The other factor that slows most computers down is junk files. These are files which either have no purpose or are damaged, and basically act like a giant maze which your computer has to pass through each time it wants to read a file. The more junk files that are on your system, the slower it will run as it will have to take longer to read all the files it needs. This is a big problem that affects mainly older computers.

The best way to fix your PC and make it run faster is to make sure that it has no junk files and no damaged registry settings. You can do this by using a software program called a “registry cleaner” to scan through your PC and remove all of the damaged settings that are inside there; as well as a “Junk File cleaner” to remove all the junk files your PC might have. There is actually a tool which does both of these tasks called “Frontline Reg Cleaner” and by downloading it and running it, you can see how many errors are slowing your system down.

A lot of Inkjet printer users opt to refill their Inkjet cartridges rather than buy original branded cartridges when their printers run out of ink. This is fully understandable. Original Inkjet printer cartridges can be quiet expensive, averaging $60 per package. Not everyone can afford to shell out that much money on printer ink, and this can be a hassle if they use their printer frequently.

If you decide to go down the refilling route, there are a couple of options open to you to refill your empty Inkjet printer cartridges with new printer ink. You can either take your empty cartridges to a refilling station or refill these cartridges yourself. When you choose the latter route, you can accomplish it by buying an printer ink refilling kit. These ink refilling kits would contain bottles of ink, syringe nozzles, refilling clips and other paraphernalia used in refilling empty Inkjet printer cartridges.

You will never find a lack of how-to guides on how to refill empty Inkjet cartridges. If anything, that is an indication of just how popular an option refilling ink cartridges is. However, there are things that you should not do when you are refilling your Inkjet cartridges, and here are some of them.

1. Ignore the instructions. When you purchase a refilling kit, it is an absolute must that you read and understand the instructions included with the kit. These instructions will tell you exactly how to go about refilling your empty Inkjet printer cartridges. Not all refilling kits work the same way, after all. If you choose to ignore the instructions and go about your own way in refilling your cartridges, you may end up wasting the replacement ink that you bought as well as damaging the ink cartridges.

2. Refill without protection. Before you start the task of refilling your empty Inkjet printer cartridges, you should first spread some newspaper on your work surface and don protective disposable gloves. Spillage is inevitable when it comes to refilling ink cartridges and ink spills are notoriously hard to clean up. So, unless you do not mind damaging your work surface or going about with stained hands, you should exercise some protective measures to prevent damage from spillage. You should even change to old clothes that you do not mind getting stained before you refill your Inkjet printer cartridges.

3. Waiting too long to do the task. Another refilling mistake that you should avoid is procrastinating on refilling your Inkjet cartridges. It is only easy to put off this task because it is not that simple to do, especially if you are going to do it for the first time. The downside of procrastinating, however, is that the longer you wait to refill your Inkjet cartridges, the higher the chances of the remaining ink inside the cartridge to dry up. If you wait too long to refill your ink cartridges, you run the chance of clogging your printer heads.

These are just a few things that you should avoid doing when refilling your Inkjet cartridges.

Formatting a hard drive is not that hard as long as you follow the steps accordingly. It is important to know how to format a hard drive because it can remove all the viruses that may have infected your computer for good. It can also remove a lot of files that are not needed anymore.

1. The first step on how to format a hard disc is to save all the important files you have on that drive. You can save files on a disc. Formatting a hard drive also means installing all the programs you have in the computer again.

2. The second step on how to format a hard drive is right clicking on the “my computer” icon on the desktop or on the start menu. Choose the manage tab and then you will see another window called “Computer management”. Choose the storage tab and click on it. Choose the “disk management” you can see on the right part and click it twice.

3. The third step on how to format a hard drive is main framing the right part of the computer screen so you get a good view of the hard drives. All the boxes are placed on each line. The lines have colored bars at the upper part. It also displays the size of the drive in MB, this is the drive’s partition. A partition is the thing that separates the drive’s capacity. If you are not doing many tasks, it is best to only have a single partition.

4. The fourth step on how to format a hard disc is deleting the partitions that existed before. You can execute this step by clicking the box with the partition twice. Select the tab for the “Delete Partition” because you know that all the files in that drive will be deleted. You should have previously save all the important files in a CD. Then you should also click yes to every pop up warning message you see afterwards.

5. The fifth step on how to format a hard drive is finding the bar that is colored black placed above. The bar should also say “unallocated” below the size. Click on it and choose the new partition option. Then the set up for it will be installed next.

6. The sixth step on how to format a hard drive is clicking the first partition on the partition wizard. Then the next move is changing the sizes. You should make the same size as the one you inputted on the maximum space. The next thing that will happen is that the computer picking the new letter for the drive. You can also rename the letter by going to the menu and clicking on the next button.

7. The second to the last step on formatting a hard drive is choosing the NTFS set up to format the latest partition. The NTFS is also safer against viruses. Do not type anything on the space allocation and just leave it as it is. The last thing to do is entering a name for the volume label.

8. The eight step is letting the wizard or set up do the formatting. It will take a longer time for older drives. Make sure that you don’t exit the “computer management” tab until it is done with the formatting. The process is finished when the healthy status shows up just below the part indicating the size of the drive.

Anybody who runs any kind of information technology-based operation who has experienced disaster knows that stomach-churning, knot-tightening feeling that always overcomes you when you need to worry about information backup. Once a crash does occur, the first thing you look to us to see if the data was properly backed up and taken off your site. At this time you also start second-guessing hoping that all those times you were going to review the restoration process and you didn’t, won’t come back to haunt you. All of worrying does you no good when you look to see that the raid array has been backed up in a timely fashion but find out that they were not taking place when they needed to take place. Now you need to seek some sort of Raid 5 data recovery.

Two Kinds of People Need Data Recovery
There are two types of IT professionals who find themselves in dire need of data recovery. The first is one that did an exceptional planning providing for primary, secondary as well as tertiary backup programs only to find out that all three of them failed at the same time. It could happen. This is happened when a large-scale disaster takes place in a single location attacking the entire system set up. However, the typical cases more like the fact that there was little proactive preplanning and you got caught unaware lacking the proper backup which now put you in a data loss situation. Most of the people associated with the computer system are in such distress at this particular point in time they may not have the proper knowledge about how to restore the data after a complete loss.

Start Spreading the News
You will be happy to know that there are several recovery strategies available that may work for you. However, these strategies are quite dependent upon the nature of the loss and how much data is missing. It will be important to know if it was a complete loss, loss of a specific drive or drives or maybe something went wrong with the array itself. Perhaps it was a hardware failure. The important thing you need to do is to consult with a professional and open up a dialogue in which you can gain enough information to understand exactly what your options might be.

Raid 5 data recovery is a lot like mining operations. You never know what you have until you start digging in the dirt.
