Walk through the doors into any real world casino and you hit the slot machines. There’s a slight difference of opinion between the casino operators. Some believe the machines are the most popular form of gambling and make everyone walk into the floor area where the machines are sited before they get to the table games. Others have a floor plan called the premium strategy that pitches their operations at the non-slot players who spend more per head on the table games. The machines are still featured as you walk into the casino, but the view of the tables is more obvious. Interestingly, there seems to be very little difference in the spend-per-machine in both layouts. The people who favor slot machines will play them no matter where they are sited in the casino. It’s also a fact that, except for the contributions made by individual whales, casinos make more money from slot machines than from the table games, the balance shifting depending on whether the premium strategy is in operation. Online, there are sites that are exclusively based on slot machines. Other sites operate the full spread of casino games. This leaves the operators to compete on the bonuses (welcome and otherwise), comps and the quality of the service. In real world casinos, the operators can comp you on the machines but it’s technically difficult to enable free play. Online, all that changes.
Every site allows all users the opportunity to play some of their games for free. Why should anyone want to play for free and give up the chance of winning some real money? The answers are both simple and complicated. The spinning reels are essentially the same in both real world and online casinos with the games easy to understand and so quick to learn. Once the reels are set in motion, all you can do is wait for them to stop moving. This means no particular skill is required to play. As a bald description, this misses out two key factors. The spinning reels are quite hypnotic. You almost feel you can reach out and stop each reel in just the right position to score a big win. Secondly, it’s fun to play. This fun element is what sells free play. Yes, you lack the extra excitement by giving up the chance of winning. But it really is still fun to play. More importantly, with more and more new games coming online every month, it’s very useful to be able to study them without risking your money. Although the basic concepts are the same, the individual variations still have to be learned. In the real world, you can stand and watch others play, learning from their mistakes. Online, you are denied this opportunity. That makes free play a fair offer from the casino operators.
There is one final reason and this may be a little complicated depending on your view of luck. Many people who play slots believe in flows of good and bad luck. If your luck is out, it’s good to be able to keep on playing for free. No-one wants to keep feeding money into a machine when you know you are not going to win. Slots and Lady Luck do go together so mix and match free and paying play as you come into and fall out of her favor.
Although there are a number of slot games repeated on some of the sites with shared operations, the reality is an expanding universe of different games. Like the Big Bang which supposedly began our universe, the inventiveness of the different software producers knows no limits. This fuels the competition for players between the sites with the endless rollout of new games. As a result, it would take you years to try them all. Nevertheless, the actual betting choices to be made come down to a few simple steps. The three main variables are the number of paylines to play on each spin, the number of coins to bet on each line, and the value of the coin(s) to bet. The majority of the games allow a free choice on the three variables. But some games restrict the choice on the second or third options (none of the major games eliminate both). So, some fix the value of the coin to be bet or only allow one coin to be bet per payline. This allows us to offer this summary. The amount you decide to bet per payline is the value of the coin multiplied by the number of coins. The total bet on each spin of the reels is the bet per payline multiplied by the number of paylines.
Now we come to an odd truth. The majority of games allow you to choose the number of paylines to play. Where the number of available paylines is great, there can be a real decision to be made. If you are betting one coin of value per payline, one hundred paylines per spin can work out quite expensive. Yet answer this question. What is the point of playing with paylines disabled? With the exception of games permitting scatter wins, you only win on enabled paylines. While this is merely a source of frustration in a conventional game when you see winning combinations on disabled lines, it can be critical on progressive machines. Often the jackpot only pays out when the highest payline has the winning combination. If the total bet looks outside your budget, reduce the value of the coins. If the bet is still too high with the minimum coin size selected, this suggests you should not be playing this game.
When you first approach a game, look carefully at the choices you can make. The critical differences lie in the coin sizes and the gaps between each coin. The best games have a big range of coin sizes with even gaps between them at the lower end and gently scaled gaps at the high end. This allows you the maximum flexibility to fit the line and total bet per spin to your budget. In calculating your budget, factor in the length of time you prefer to play. Slots is a game meant to be fun. If you burn your budget in ten minutes, this is not fun. Always remember to set a loss limit before you start playing. Decide the point at which you will stop. Slots is only fun so long as you are not digging yourself out of debt for the next six months. If you win, as everyone does from time to time, you should also stop. These winnings can buy you a drink and a meal. They can pay for your next session of play.
Given the history of some games starting in China around 2000 B.C., the question naturally arises as to what makes any game popular. The first games to achieve success were based on dice. It probably all started around the fire in the cave when, having stuffed themselves with dinosaur rib at the bar-b-q, they moved on to a little action with a few carved bones. But, as time progressed and money was developed, the idea of money changing hands based on a throw of the dice caught on. In this, you see all the key elements making any game popular. The concept of gambling is seductive. You place a small wager on the outcome of an event outside your ability to control.
If you win, there’s a big profit and this is a compelling reason to carry on playing because you believe you will win again. The second feature is the sociable nature of the playing environment. There’s a crowd watching. Sometimes it’s only other players but, more often, gambling is a spectator sport. This creates a community and it supports and encourages the players. Rich backers appear and bankroll the best players for a share of the expected profits. Add in good customer service from whoever provides the playing environment, and the honey pot nature of the exercise is complete. As to the game itself, it must be fun to play. It must be easy to understand the rules. Everyone must be able to see the skill or luck of the winners. And, the organizers must make realistic attempts to prevent or control cheating.
So where does this leave us? In the modern casino, both online and real world, the most popular games are probably blackjack and poker on the card tables, craps and roulette on the other tables. All four are simple to understand. The cards must add up to 21 or a limited number of card combinations makes you the winner. Or you bet on the throw of dice or the spin of wheel. It takes only a few minutes to explain. You watch for a while and then you feel confident enough to play. It’s almost immediately exciting. You handle the dice and throw. You finger the chips and play the cards. All with money riding on the outcome. If your luck is in, you end up a winner and most are hooked. The problem with more complicated games is people do not want to put in the effort to learn. They must see it, see others win and feel confident they can start winning immediately. Any game where it looks easy to win big money is popular.
Now when you transfer the experience on to the small screen of a computer and strip away everything about the experience of being in a casino, the true popularity of online casino games is revealed. Slots are slots. You click on “play”, the animated reels spin, and you win or lose. It has a hypnotic quality. Click, spin, win. It’s the same with blackjack, craps and roulette where you are betting on the results produced by the random number generator. Poker remains interactive where you bet on the cards and your skill in playing them. In all, it’s the belief you will win big that makes casino games popular.
More or less any place you go on the internet, you can see goods or services you want and pay for them. Most sites accept credit cards. Those that do not, deal with the other players in the banking world to make sure the funds get where they are supposed to go. This works whether you are buying clothes for your newborn baby or hard core pornography. E-commerce is the new life blood of trade. Yet, when it comes to online gambling, something dramatic happened in the US. If you are resident anywhere else in the world, all the standard methods for transferring money work with online casinos. You can open an account using a credit card and your winnings can be transferred to any bank account you nominate. But, if you are resident in the US, the world was turned on its head by the Unlawful Internet Gambling Enforcement Act of 2006 (UIGEA). The history of this is revealing.
A bill dealing with security in our ports was working its way through the legislative process and, at the last moment, the internet restrictions were added. They had nothing to do with the security of ports. It was a device to slip the law through without real debate. As a result, it suddenly became illegal for any financial institution to transfer funds to an internet gambling operation except for horse racing, online lotteries and fantasy sports. So states protected their revenue streams with lotteries and the racing industry gained an edge over all their competitors. This law is probably unconstitutional but, so far, the courts have been reluctant to give clear rulings. This leave US players with real problems. No matter where the online casino is based, it’s still difficult to open an account and recover winnings. So how do you get round the law?
The first option is to use eChecks. This produces an immediate electronic funds transfer between your bank account and the payee casino. They work in exactly the same way as paper checks. But a word of caution – one company providing this service was recently shut down by the Attorney General of New York. Although other companies continue to offer eChecks, this method is risky with winnings being seized in the New York court action. The alternatives are the following. A limited number of casinos including Rushmore accept American Express, bank drafts, wire transfers and checks for opening an account and making deposits. But these methods cannot be used for withdrawals. This brings us down to Central Coin, Citadel, Click2Pay, CLICKANDBUY, NETeller and others. Online casinos pick and choose which methods they accept. Alternatively, you have to set up a third party account outside the US and transfer the funds into and out of that account instead of directly to the casino.
It should not be this difficult to play your favorite casino games and there are various moves in the pipeline to encourage the lawmakers to repeal this oppressive law. While there’s no constitutional right to gamble as such, this law chills the banks and achieves prohibition by the backdoor. While we wait for either a definitive court ruling or Washington to act, find the online casino with the payment methods you can access and set to enjoying your favorite online casino games.
Companies must account and deal for new legislation governing how information is stored on IT systems.
The EU is shortly to adopt many of the recommendations on corporate governance set out by the Sarbanes-Oxley Act in the US, UK firms are to be expected to deal with and manage explicit guidelines on how to store email and other documents on their IT systems. IT managers should consider the necessary procedures and technologies needed for compliance now, in order ensure technology is able to deal with the new legislation.
Regulations regarding data storage at the moment are fairly lax, but there will be a huge increase in the amount of data than must be held over the next 18 months to two years.
Email archiving, the increased use of expencive write-once read-many media, information lifecycle management and content-aware storage as a few of the technologies which firms should consider for the future, though in some cases companies will simply need to improve the way they manage existing systems.
It is anticipated that new legislations will demand that an organizations’ archiving solutions must guarantee that the information they hold has not been changed, and keep it for a specific period of time before automatically deleting it.
A survey of 493 companies in the UK has shown that compliance with regulations has a high or fairly significant impact on the data storage strategies of 87% of the organisations surveyed. Back-up and recovery was also very important to the data protection strategy of 93% of organisations.
78% of organisations future storage strategy is set to include Disk-to-Disk-to-Tape technology. This may be due to the highly affordable and flexible nature of this new technology. For example, recent deployments of disk-to-disk-to-tape (D2D2T) solutions by various companies have, on average, reduced the backup window by more than 70%, from fifteen hours to less than four, yielding significant time and cost savings in tape management.
Interestingly, product features were far more important than the brand of the product, with 82% of organisations making a decision based on product features. When it came to the decision of choosing a specialist storage supplier or a general IT provider for storage solutions there was a very slight preference for specialised storage suppliers (51%) over general IT providers (49%).
This survey shows that compliance with regulations is a key driver in companies’ storage security policy and that we are likely to see more companies deploying Disk to Disk to Tape technology in the future.
All the above is fine if you are a corporate, you have an annual IT budget of £500,000 and numerous members of staff who can plan and complete such a system. Is it very easy to talk about SANs, NAS’s Virtual Tape Libaries. Organisations of this nature already have a very stable and flexible infrastructure, where it is comparably easier to implement such a system.
What about the 1000’s of smaller companies such as solicitors, accountants, medical practices and manufactures etc, which may have only 2 servers on site, but still have the same reliance on data and have to adhere to the same legislations? Backup to tape is an option, however, there is an upfront cost and a requirement for a trusted member of staff to take the tapes off site every night and store in a safe place. Can you guarantee your backup has worked, and do you really trust your long term data on magnetic media? Another option is to archive your data onto optical devices, however the cost is even more prohibitive than tape and you still need to take the disk offsite.
No doubt your data is growing quickly; recently enforced legislations makes sure of this, so why not employ a backup and archival solution which has no upfront cost, is fully automated, secure and regardless of disaster will ensure your data is always available, Offsite Backup.
When you store important information on a USB device, you take the chance of losing that information. Losing data on a USB can be kind of a mystery, but there are companies out there that can help you get that data back. These companies use engineering that can recover your lost data over ninety six percent of the time. These companies can even recover data that has been stored on a damaged USB device. So when you find yourself in a situation where you have lost valuable information you should not assume that this data can not be retrieved.
There are some companies that specialize in repairing damaged USB memory devices. In the process of retrieving your data, companies can also repair your device. Types of the problems they can repair broken solders, loose plugs, and broken internal connections. Some of the devices that they can fix are USB ports, USB sticks, USB drives, USB thumb drive, and Flash memory devices. These companies use a type of recovery called a jump drive recovery. They can recover any files from any type of USB drive or memory stick. Sometimes the chips inside the devices will be damaged, but don’t fret; there are some companies that can fix that problem too.
So the conclusion on USB data recovery is that just because information seems to have disappeared, doesn’t mean that it is lost forever. There are companies that can find and retrieve lost data on a damaged or removed USB device. In the process of finding data, the problems that caused the data to go missing in the first place will be fixed. This is helpful because it insures that it won’t happen again. There are programs out there that can help you retrieve your data by yourself, but the problem might be bigger than you know, so you should always seek professional help. There could be problems inside your device that prevent your device from working properly.
Flash memory gets its name due to its microchip arrangement in such a way, that its section of memory cells gets erased in a single action or “Flash”.
Both NOR and NAND Flash memory were invented by Dr. Fujio Masuoka from Toshiba in 1984.The name ‘Flash’ was suggested because the erasure process of the memory contents reminds a flash of a camera, and it’s name was coined to express how much faster it could be erased “in a flash”. Dr. Masuoka presented the invention at the International Electron Devices Meeting (IEDM) held in San Jose, California in 1984 and Intel recognizes the potentiality of the invention and introduced the first commercial NOR type flash chip in 1988, with long erase and write times.
Flash memory is a form of non-volatile memory that can be electrically erased and rewrite, which means that it does not need power to maintain the data stored in the chip. In addition, flash memory offers fast read access times and better shock resistance than hard disks. These characteristics explain the popularity of flash memory for applications such as storage on battery-powered devices.
Flash memory is advance from of EEPROM (Electrically-Erasable Programmable Read-Only Memory) that allows multiple memory locations to be erased or written in one programming operation. Unlike an EPROM (Electrically Programmable Read-Only Memory) an EEPROM can be programmed and erased multiple times electrically. Normal EEPROM only allows one location at a time to be erased or written, meaning that flash can operate at higher effective speeds when the systems using; it read and write to different locations at the same time.
Referring to the type of logic gate used in each storage cell, Flash memory is built in two varieties and named as, NOR flash and NAND flash.
Flash memory stores one bit of information in an array of transistors, called “cells”, however recent flash memory devices referred as multi-level cell devices, can store more than 1 bit per cell depending on amount of electrons placed on the Floating Gate of a cell. NOR flash cell looks similar to semiconductor device like transistors, but it has two gates. First one is the control gate (CG) and the second one is a floating gate (FG) that is shield or insulated all around by an oxide layer. Because the FG is secluded by its shield oxide layer, electrons placed on it get trapped and data is stored within. On the other hand NAND Flash uses tunnel injection for writing and tunnel release for erasing.
NOR flash that was developed by Intel in 1988 with unique feature of long erase and write times and its endurance of erase cycles ranges from 10,000 to 100,000 makes it suitable for storage of program code that needs to be infrequently updated, like in digital camera and PDAs. Though, later cards demand moved towards the cheaper NAND flash; NOR-based flash is hitherto the source of all the removable media.
Followed in 1989 Samsung and Toshiba form NAND flash with higher density, lower cost per bit then NOR Flash with faster erase and write times, but it only allows sequence data access, not random like NOR Flash, which makes NAND Flash suitable for mass storage device such as memory cards. SmartMedia was first NAND-based removable media and numerous others are behind like MMC, Secure Digital, xD-Picture Cards and Memory Stick. Flash memory is frequently used to hold control code such as the basic input/output system (BIOS) in a computer. When BIOS needs to be changed (rewritten), the flash memory can be written to in block rather than byte sizes, making it simple to update.
On the other hand, flash memory is not practical to random access memory (RAM) as RAM needs to be addressable at the byte (not the block) level. Thus, it is used more as a hard drive than as a RAM. Because of this particular uniqueness, it is utilized with specifically-designed file systems which extend writes over the media and deal with the long erase times of NOR flash blocks. JFFS was the first file systems, outdated by JFFS2. Then YAFFS was released in 2003, dealing specifically with NAND flash, and JFFS2 was updated to support NAND flash too. Still, in practice most follows old FAT file system for compatibility purposes.
Although it can be read or write a byte at a time in a random access fashion, limitation of flash memory is, it must be erased a “block” at a time. Starting with a freshly erased block, any byte within that block can be programmed. However, once a byte has been programmed, it cannot be changed again until the entire block is erased. In other words, flash memory (specifically NOR flash) offers random-access read and programming operations, but cannot offer random-access rewrite or erase operations.
This effect is partially offset by some chip firmware or file system drivers by counting the writes and dynamically remapping the blocks in order to spread the write operations between the sectors, or by write verification and remapping to spare sectors in case of write failure.
Due to wear and tear on the insulating oxide layer around the charge storage mechanism, all types of flash memory erode after a certain number of erase functions ranging from 100,000 to 1,000,000, but it can be read an unlimited number of times. Flash Card is easily rewritable memory and overwrites without warning with a high probability of data being overwritten and hence lost.
In spite of all these clear advantages, worse may occur due to system failure, battery failure, accidental erasure, re-format, power surges, faulty electronics and corruption caused by hardware breakdown or software malfunctions; as a result your data could be lost and damaged.
Flash Memory Data Recovery is the process of restoring data from primary storage media when it cannot be accessed normally. Flash memory data recovery is a flash memory file recovery service that restores all corrupted and deleted photographs even if a memory card was re-formatted. This can be due to physical damage or logical damage to the storage device. Data even from damage flash memory can be recovered, and more than 90% of lost data can be restored.
USB which stands for Universal Serial Bus is a standard for serial communications between computers and other devices. It was first introduced in 1996 and was jointly promoted by Intel, Phillips, US Robotics and Microsoft. USB was developed so that many different types of devices could be accommodated under a single common interface. Due to this capability, nowadays USB devices are the most popular form of plug and play devices. In short, a plug and play device is an external device which we connect to the computer either for data transfer or to provide additional capabilities to the computer. Normally plug and play devices are used along with additional software which acts as a link between the device and the CPU of the computer. This software is called the driver.
Many other standards exist for such connections like PS2, but USB devices provide a distinct advantage over other standards mainly due to two significant reasons.
First, the USB standard allows devices to be connected to the computer without needing to restart the computer. For many previous standards, the computer needed to be restarted before the device could be used. Secondly, the USB device takes its power supply directly from the CPU thus eliminating the need for an external power supply cord. This was only possible due to the fact that USB devices typically consume very little power.
Nowadays USB devices are used for a number of purposes. The most popular adaptation of the USB devices is in the form of USB drives (also called pen-drives). These are basically devices which offer portable data storage facilities. Often these devices are as small as a keychain. With the advent of technology, USB drives can now store as much as 200GB of data and still appear very small.
Another important use of USB is for webcams which allow us to transmit and store photos and videos directly on our computers. Apart from these uses, USB also allows us to connect audio devices like iPods, microphones and speakers, network between different computers with USB routers and also provides an interface to link our other gadgets like mobile phones and PDAs. With Windows becoming more common it is now simpler to synchronize our gadgets as windows can automatically recognize and install our USB devices. Another new technology which is making waves is USB 2.0, which provides data transfer speeds of up to 480mbps (Megabytes per second).
The cutting-edge USB data storage devices make data storage easier and more portable. While the contents of everyone’s computer are unique in nature, the need to store, transport and archive data is almost universal. Unless you use your computer for occasional letter writing, email and marathon games of solitaire, you will need a data control strategy at some point. The first step in planning your strategy is to analyze the way you use your computer. Then you can determine what you want to save and whether to save it on an external drive, DVD or a USB data storage device.
All Work and No Play
Start with the work you do with your computer. Do you use it for professional reasons? Do you use it to keep records for a personal business? Are you working on the great American novel? Consider anything that needs to be archived; including completed projects that need to be saved should be backed up. Large projects can go on DVD’s if you have a burner. They can hold much more than CD’s and you can save a little money by storing completed work on record-only DVD’s. Work in progress can go onto rewritable DVD’s so that they can be updated periodically. If you like to bring digital work home, the answer is a USB data storage device. Work can be carried safely and compactly home, worked on and then resaved and brought back to work.
Some hobbies should also be backed up, of course. Any files that you don’t want to lose should be placed on removable storage and kept in a safe place. If you have ever lost a hard drive, you may feel the need to back up your programs as well as your files. Rebuilding a hard drive is an unpleasant task. You can buy a removable hard drive to create a copy of your basic set up. This includes your programs and the settings that you prefer. This keeps a copy of your programs safe from virus infections.
When you have files that need to travel, you should use a USB data storage device. A video project for a birthday party, digitally enhanced photos for a wedding shower or the latest videos from your favorite family rock band are excellent files to carry around on your USB data storage device. It is a temporary way to backup the entertainment as well as the best way to transport the life of the party to the party.
If you place an Autorun.inf file in the root folder of a CD or DVD and the Autorun.inf file contains an OPEN command pointing to a program file (e.g. OPEN=MYAPP.EXE), the program is launched automatically when you insert the CD/DVD in a drive. But if you place the same Autorun.inf file and program file in a USB flash drive and plug the drive to a USB port in a computer, the program is very likely not started automatically. Instead is a Windows menu shown, that contains a list of actions (commands) you can do on the USB drive.
