Computing Meets the Physical World

 

Rapid changes in computing will continue for the foreseeable future.

The field of computing has always changed rapidly, and it is still doing so. The changes are driven, more than anything else, by Moore’s law. Many people think the pace of change is slowing, or even that because we already have the Internet and Google, there is not much left to do. I hope these papers will convince you that this view is entirely wrong.

For the last 50 years, new applications of computers have followed a pattern, as one manual activity after another has become automated. In the 1940s, it became possible to automate the calculation of ballistic trajectories and in the 1950s of payrolls and nuclear weapon simulations. By the 1970s, it was possible to create reasonably faithful representations of paper documents on computer screens. In the 1990s, we had the equivalent of a telephone system for data, in the form of the Internet. In the next two decades we will have embodied computers, machines that can interact with the physical world.

Hardware and Software
The factor that determines whether or not an activity can be automated is whether the hardware is up to it. According to Moore’s law, the cost performance of computers improves by a factor of 2 every 18 months, or a factor of 100 every 10 years; this applies to processing, storage, and communication. Moore’s law is not a law of physics, but it has held roughly true for several decades and seems likely to continue to hold true for at least another decade. Indeed, today some things are developing much faster than that. Storage capacity, for example, is doubling every 9 months, not every 18 months. Wide-area communication bandwidth is also improving faster than Moore’s law. Sometimes, with speech recognition and web search engines, for example, the cheaper cycles or bytes can be applied directly. Often, however, by spending more hardware resources, we can minimize programming effort; this is true for applications that use web browsers or database systems.

Hardware is the raw material of computing, but software gives it form. Our ability to write software is limited by complexity. People have been complaining about the “software crisis” at least since the early 1960s, and many people predicted in the 1960s and 1970s that software development would grind to a halt because of our inability to handle the increasing complexity of software. Needless to say, this has not happened. The software “crisis” will always be with us, however (so it isn’t really a crisis). There are three reasons for this:

As computing hardware becomes more powerful (at the rate of Moore’s law), new applications quickly become feasible, and they require new software. In other branches of engineering the pace of change is much slower.
Although it is difficult to handle complexity in software, it is much easier to handle it there than elsewhere in a system. Therefore, it is good engineering to move as much complexity as possible into software, and engineers are busily doing so.
External forces, such as physical laws, impose few limits on the application of computers. Usually the only limit is our inability to write programs. Because we have no theory of software complexity, the only way to find this limit is by trial and error, so we are bound to overreach fairly often.

A lot of software today is built from truly gigantic components: the operating system (Windows or Linux), the database (Oracle or DB2), and the browser (Netscape or Internet Explorer). These programs have 5 million to 40 million lines of code. By combining them with a little bit of new code, we can build complex applications very quickly. These new applications may use a hundred or a thousand times the hardware resources custom-built programs would use, but they can be available in three months instead of five years. Because we have plenty of hardware resources, this is a good way to use them. It is programmers and time to market that are in short supply, and customers care much more about flexibility and total cost of ownership than about the costs of raw hardware.

Another way to look at this is that today’s PC is about 10,000 times bigger and faster than the 1973 Xerox Alto, which it otherwise closely resembles (Thacker, 1988). A PC certainly doesn’t do 10,000 times as much, or do it 10,000 times faster. Where did these cycles go? Most of them went into delivering lots of features quickly, which means that first-class design had to be sacrificed. Software developers traded reductions in hardware resources for shorter time to market. A lot of cycles also went into integration (for example, universal character sets and typography, drag and drop functions, spreadsheets embedded in text documents) and compatibility with lots of different hardware and lots of old systems. Only a factor of 10 went into faster responses.

Applications
There have been three broad waves of applications for computers, about 25 years apart. Currently, the communication wave is in full flood, and the first signs of embodiment (relatively unrestrained interactions with the physical world) are starting to appear. Of course the earlier waves do not disappear, simulation continues to be an important class of applications.

Usually a computer application begins as a fairly close simulation of a manual function. After 10 or 20 years, people begin to explore how the computer can do the job in a radically different way. In business, this is called “business process reengineering.” The computer no longer does the same things as a bookkeeper; instead, it makes it possible to close a company’s books two days after a quarter ends. Boeing builds airplanes in a very different way because computers can model every mechanical detail.

The earliest computers in the 1950s were used for simulation. Simulations of nuclear weapons, astrophysics, protein folding, payrolls, project scheduling, games, and virtual realities all fall comfortably into this category.

The communication wave became apparent outside of research laboratories around 1980, and we are now in the middle of it. Today, we have e-mail, search engines, and the ability to buy airline tickets, books, movie tickets, and almost anything else online. TerraServer, gives us access to publicly available satellite telemetry of the world. The Library of Congress’ catalog is online, and you can buy any one of a million and a half books on Amazon.com. Conduct a search on Google today, and in half a second you can research a database of about 3 billion pages that is updated every two weeks – and will soon be updated in real time.

The next great wave, which is just beginning, is embodiment. Of course, computers have been used in process-control systems for a long time, but that is comparatively uninteresting (albeit of considerable economic importance). We are now seeing the first computer systems that can function effectively in the real world – computerized cars, robots, smart dust. They are still in their infancy, but the most interesting developments in computing in the next 30 years will be in this domain.

A Boston company called iRobot has just introduced what seems to be the first plausible domestic robot, a vacuum cleaner that crawls around a room in a vaguely spiral pattern, bouncing off of things (see it at www.roombavac.com). The price is 9. In fact, with only 14k bytes of ROM and 256 bytes (not kilobytes) of RAM, it’s barely a computer.

What’s Next?
In a recent paper, Jim Gray (2003) countered the widely held perception that most of the important developments in computing have already happened and that the future holds little more than refinements and cost reductions. Gray predicted that the next 50 years would be much more exciting than the last 50, both intellectually and in practical applications. Here are some of the challenges he raises.

Win the impersonation game. The classic Turing test asks whether a person sitting at a keyboard and display can distinguish between a conversation with a computer and a conversation with another person. To win, roughly speaking, a computer must able to read, write, think, and understand as well as a person. The computer will need some facility with natural language and a good deal of common sense. Anyone who has tried using natural language to interact with a computer knows that we still have a long way to go; and we don’t even know how far.

Hear, speak, and see as well as a person. Meeting this challenge will be much more difficult. Today’s best text-to-speech systems, given enough data, can do a pretty good job of simulating a person’s voice, although they still have trouble with intonation. In a quiet room, you can dictate to a computer a little faster than a person can type, at least if, like me, the person types fairly fast but makes a lot of errors. If there is any background noise, however, the computer does much worse than a person. To see as well as a person is even more difficult. People first learned to parse two-dimensional images on the retina and construct a model of a three-dimensional world so they could detect tigers in the jungle and swing from tree to tree. Today’s best systems do a fair job of recognizing buildings on a city street, but not in real time.

Answer questions about a text corpus as well as a human expert. Then add sounds and images. A computer can’t yet read and absorb Google’s 3 billion web pages and then answer questions about them in a sensible way. It can find documents where words occur or documents with a lot of other documents pointing to them, but it can’t understand content.

Be somewhere else as observer (tele-past), participant (tele-present).Videoconferencing represents the first feeble step in this direction. Can virtual presence equal real presence? We don’t really understand what makes real presence good, so this is an open question – one that has implications for medicine, transportation, education, and social relations. Remote surgery is just one valuable, but extremely demanding application.

Devise a system architecture that scales up by 106. Computer systems on the Internet often serve millions of users, sometimes hundreds of millions, and the demand can change rapidly. After September 11, for example, the main web news sites collapsed because traffic was 10 to 100 times higher than normal. In addition, the same architecture must be used across a wide range of systems to ensure compatibility and consistency. The Internet has met this challenge for transporting data, but storage, processing, and coordination over such a range of sizes are problems yet to be solved.

Given a specification, build a system that implements it. Do it better than a team of programmers. Writing an adequate specification is a daunting task, as anyone who has tried it knows. Automatically building a system to implement it means converting it into a form that can be executed reasonably efficiently. Most teams of programmers don’t do this terribly well, so if we can create a system that can do it at all, we have a good shot at doing it better than a team of programmers. Today, we can do it in very limited domains; the canonical examples are certain spreadsheet and database query applications, in which the specification and the program are almost indistinguishable.

Build a system used by millions that can be administered by half a person. The operating costs of most computer systems dwarf their hardware costs. Configuration, backup, repair, expansion, and updates require a lot of human attention. There is no reason in principle why this work can’t be done by machines, except for the small effort required to set policy (e.g., telling the system who the authorized users are and which tasks are most important).

Common Themes
Three themes common to these challenges are central to the way computing will develop in the next few years and decades: information, uncertainty, and ubiquity.

Information. Very soon it will be technically feasible to put everything we have online and remember it forever. But making the most of this capability will require that the information be meaningful to the machine in some sense. Even though today’s web is feeble by this standard, it has already had a tremendous impact on our lives. Machines that can answer questions about the information they store and relate different pieces of information to each other would be able to do much more for us.

Uncertainty. Interacting with the physical world necessarily involves dealing with uncertainty. The computer needs a good model of what can happen in the part of the world it is interacting with, and boundaries that tell it when the model no longer applies. This is often called common sense, and it is essential not only for sensors and robots, but also for natural user interfaces, such as speech, writing, and language. For each of these, the machine often has to guess meaning; it needs to guess well, and the user needs to know what to do when the guess is wrong.

Ubiquity. Computers are getting so cheap and so small that we can begin to think about having a computer on every fingernail, a computer inside every manufactured physical object. We could have guardian angels, for example, that monitor the state of our health and safety, call for help when it’s needed, and so forth. Every manufactured object in the world could respond to us and interact with its fellows. How can all of this be done reliably and conveniently? How can people tell all of these computers what to do?

These are just a few examples of the opportunities before us. The papers that follow focus on physical ways computers might interact with the world.

Common Computer Threats that Call for Professional Computer Services

There are some of the most common and most problematic computer threats that call for expert computer repair. Almost all the setbacks could lead to data loss, so there will eventually be a need for an appropriate data recovery program.

Computers are complicated. As electronics, they can be very demanding. You need to regularly invest in computer services and important software that are pertinent to ensuring performance and data processing will also be in good condition. However, there are some problems that could serve as major nightmares. You practically will not want to lose data or fall prey to online hacking activities. It is in this regard that computer repair experts identify different and common computer threats that could bear major impact to overall computer use.

Here are some of the most common and most problematic computer threats that call for expert computer repair. Almost all the following setbacks could lead to data loss. There are data recovery procedures, but only if you will invest additional costs on getting a computer repair.

Slow running PC – Slow running PC is one of the most common computer problems computer repair shops usually fix. Everyday, there are many users who are complaining about the slow performance and processing of their laptops and desktops. Worse, users tend to figure out ways to boost speed, only to find out that they have made the situation practically worse. Alas, errors applied could be a cause of data loss. Data recovery is not basically recommended for slow running PC but if major damages are incurred due to initial and wrong measures to remedy the situation, there surely will be a need for one.

Harmful Trojans – Conventionally, a Trojan is installed into the computer without a user’s knowledge. Nashville computer repair shops assert that annually, a great portion of their total computer services rendered are comprised of Trojan infection. Unknown to many, a Trojan could help computer hackers take control and manipulation of your computer. Thus, any important data or file you may have stored into the PC could be inappropriately accessed by unscrupulous hackers. The presence of the malware could also lead to other more serious problems.

Data loss, computer crash, data hacking and performance slowdown are some of the common computer problems resulting from presence of malware, a type of spyware or malicious software that can be installed on computers without owners’ knowledge and consent. The Trojan is one of the most common and dreaded malware types that are rampantly affecting different types of computers. In Nashville, Trojans are among the most usual causes of computer problems.

Computer crashes – The computer may eventually crash if there is overuse. If the memory gets too congested and full, crashes could also emerge. Many computers crash without warnings. Worse, in such crashes, data loss is usually surfacing. If your computer crashed, there is a need to immediately seek computer services because there is nothing you could do to revive the system. A reformat may be needed.

Common Misconceptions About Computer Repair

There are common misconceptions that have been discouraging many computer owners from taking expert computer repair services.

Nashville computer repair shops thrive because the number of computer users continues to climb. Like in most cities around the United States, more and more households in Nashville, Tennessee recognize the value and importance of owning and maintaining a reliable and functional computer at home. The rise of numerous businesses, great or small, also contribute to the growing number of computer users in the area.

Because there are more computer users, there is a higher demand for computer repair shops to cater to computer owners and users in Nashville and in surrounding areas like Green Hills, Belle Meade, Franklin and Brentwood. However, there are still many computer users who are having misconceptions about computer repair activities and businesses. Nashville computer repair shops have been doing their best to collectively reassure clients about computer services available.

Here are the most common misconceptions about computer repair in Nashville. Repair experts aim to further enlighten users about the advantage and assistance they offer.

Nashville computer repair services are very expensive. This could almost qualify as an urban legend. This misconception may have emerged due to word of mouth started by previous computer repair clients who think they have spent too much from their computer services. Expensiveness of repair services is relative. Logically, such costs are costly to some, cheap to others and just reasonable to many. If you want to maximize the value of your money, you could get quotes first and do comparison-shop before getting a computer service from any shop.
Computer shops incur other possible damages to computers to ensure clients will keep on coming back. This misconception has for some time discouraged computer owners from getting expert computer services. Nashville computer repair shops assert that such misconceptions could never be truthful as they are all protecting their integrity and credibility as business establishments.
Computer services take forever. This is not true. In fact, most computer repair tasks can be completed in just a few hours. You can bring your personal computer to a Nashville repair shop and wait until it is fixed or agree to pick it up later in the day. However, there are times when such shops have too many clients so you may have to fall in queues. For your convenience, you can even opt for home services.
Computer repair shops steal from the inside of your computer or replace certain parts with old ones. For your peace of mind, you could ask the repairmen to do the task in front of you. Repair shops are businesses and as such, will not in any way try to cheat on you because doing so could tarnish their image.

You could actually perform the tasks done by computer repair experts. Many computer users have fallen into this pit. The result: computer damages and problems worsen and repairs become more difficult, making tasks harder and repair charges higher.

Need to Rent a Computer: Use These Money-Saving Tips

There are many different situations where you might need to rent a computer. Maybe your own computer is getting repaired and you need a temporary replacement. Or maybe you’re traveling out of town to give a presentation and you need a computer on-site at your destination to use for work purposes.

No matter what the reason is for renting a computer, there’s one thing that everyone has in common. Everyone likes getting a good deal. Simply put, you don’t want to spend more money on renting a computer than you have to. And if you follow the tips in this article, you won’t have to.

The first thing you need to do is figure out what kind of computer rental services you need. Are you renting a laptop? A desktop? Do you need a Mac? How many computers do you need to rent? When do you need them by? And how long will you be keeping the computer for?

That’s a lot of questions to answer, but each of them is very important.

So, what kind of computer do you need? The best computer rental companies offer a huge selection of computers from all manufacturers. Whether you need an HP laptop or a Macbook, you should be able to find what you need when you choose a reputable equipment rental company with large inventory.

How many computers do you need? If you just need one computer for yourself, most computer rental companies will probably have what you’re looking for. But what if you need computers for your employees on a temporary job site? That’s why it’s always a good idea to work with a company that has a huge inventory of computers. This way, they’ll be able to accommodate you no matter how large or how small your order ends up being.

When do you need your computers delivered by? In many cases, you’ll find that you need to rent a computer fast. That’s why it’s important that you choose a computer rental company that guarantees overnight delivery to your destination. The best rental companies will get your order to you same day or next day no matter where you are in the United States. Make sure you choose a fast, reliable computer rental company that can do the same.

How long do you need to keep your computers for? In some cases, you might just need a computer rental for a day. Other times, you may have a long-term project that requires you rent the computers for a few weeks. Make sure your computer equipment rental company can accommodate your special demands.

It’s important to remember that not all companies offering computer rentals are the same. You need to make sure you choose an experienced, reliable company that can give you the best equipment at the lowest possible price.

The best rental companies have a low price guarantee. This means that they promise to give you the lowest price on computer rentals no matter what. So if you find it cheaper somewhere else, they pledge to match or beat that price. It’s the only way to guarantee you get the best possible deal on computer renting.

So spend some time looking around online to find a computer rental company with a lowest price guarantee. And then make sure that you shop around at the competition to see if they have cheaper rates. If they do, your computer rental company will have to match or beat that price to give you the very best deal available.

Southern New England Computer Services Answers All Your Computer Needs?At Low Cost

If you’re looking for a computer that is “basic” to address the needs of your youngster or a senior citizen who just wants to take it home, plug it in and run it to do e-mails or write a paper, check out Southern New England Computer Services in North Smithfield, R.I.

Of course, if you’re a “techie” and are into the complexities of computer life, you can do your one-stop shopping at the same place. If its computer related, they have it!

Co-owners Paul Riendeau and Nick Bernfeld are on hand at the store to answer your questions or to provide you with the needed desktop, laptop, laser printer, or component that you need to get going. They can also simply repair, update, and checkout your present system. They will have you returning home pleased and fully satisfied. You’ll be smiling, too, if you contact them by phone with your questions since you’ll have one of them live on the phone with you—not someone overseas with an impersonal voice. “You can talk to the person who sold you the computer.”

Paul and Nick started with the idea of their own business in the basement of Paul’s home after they started helping their friends with their computer problems. They were encouraged to open their own business—which they did in May of 2002, after many friends were satisfied with their repaired computers. On their 7th anniversary coinciding with this issue of the Uxbridge Times, the computer gurus are doing extremely well despite the tight economy. They are proud to note that their Internet Café, half of the building they occupy, is available to anyone to use for only an hour if, for example, they can’t use their own computer “because it’s being serviced.” Nick was pleased to note that “We are very steady even in these tough times.”

Paul says their “business has grown” and their expertise in servicing high-end names like HP, Acer, Compaq, and Gateway, among others, gives them the edge in providing top drawer, “crème de la crème,” service “for all makes and models.” “We can service any computer.”

Paul further explained that Southern New England Computer Services can transfer data from your current computer to a new one and noted that they are known “to be the fastest service around.” They will also suggest an alternative way of backing up your important data to prevent data loss in the future, which includes DVD’s, external hard drives, or even flash drives. In addition, they deal with the complicated affairs of supporting Information Technology for companies that can’t afford an IT staff, “like a small business.”

He said that “customers trust us” because they know that Nick and he will keep costs down and will advise you on the best computer for your needs. Also, regarding repairs, their computer technicians can fix most computers, many for “under 0 since we stockpile all parts and we can debug or add an anti-virus program at a minimal price.”  Paul continued to stress that his computer store is not a “box store” and that, when you leave their store, you have a computer with exactly what you need installed, along with an anti-virus program in place; no need to go out and buy a spam protection program. “We make sure you don’t get the trial software you don’t want and provide you, instead, with all the updates you want.”

For example, Southern New England Computer Services will diagnose your computer for a “bench fee of ” versus “0 at a box store.”  In addition, “If you don’t think your computer is worth keeping, we’ll credit the towards a new computer.” “It’s a win-win situation.”

Southern New England Computer Store is well organized and very clean. Every piece is tagged. Because of its appearance, Paul and Nick added that “people feel comfortable here.”

The trip to Southern New England Computer Services is worth it and if you want a preview of this outstanding computer store, check out their very informative “high-tech” website, SNECSLLC.COM, or if you’re already convinced this is the place for you, cruise on over to this exceptional computer store located at 601 Great Road in North Smithfield, R.I.

Miami Computer Repair And computer repair and upgrade

If you have a slow computer, don’t worry. You can make slow PC repair by yourself. In reality, you require installing anti-virus software to guard your machine as soon as you can. If you utilize your PC and internet in a regular way, elude downloading and opening the suspicious files. Frequently, effective anti-virus software can really assist you in fixing the slow PC entirely. It is also recommended to extend the RAM up to 2 gigabytes if your machine is exceedingly slow. If ineffective computer productivity is influenced by the lack of RAM, then you need simply to add memory. In this case you can fix the PC slow speed issues in no time. But that’s not all.

The History and Future of Computers

With the advances in computer technology it is now possible for more and more Canadians to have personal computers in their homes.  With breakthroughs in computer processing speeds and with computer storage capacity, the combination of this with the reduced size of the computer have allowed for even the smallest apartment to hold a computer.  In the past the only places to have computers were military institutes and some universities; this was because of their immense size and price.  Today with falling computer prices and the opportunity to access larger networks, the amount of computers has grown from just 10% in 1986 to 25% in 1994.  Also, of the 25%, 34% of them were equipped with modems, which allow for connection to on line services via telephone lines.

The primitive start of the computer came about around 4000 BC; with the invention of the abacus, by the Chinese.  It was a rack with beads strung on wires that could be moved to make calculations.  The first digital computer is usually accredited to Blaise Pascal.  In 1642 he made the device to aid his father, who was a tax collector.  In 1694 Gottfried Leibniz improved the machine so that with the rearrangement of a few parts it could be used to multiply.  The next logical advance came from Thomas of Colmar in 1890, who produced a machine that could perform all of the four basic operations, addition, subtraction, multiplication and division.  With the added versatility this device was in operation up until the First World War.

Thomas of Colmar made the common calculator, but the real start of computers as they are known today comes from Charles Babbage.  Babbage designed a machine that he called a Difference Engine.  It was designed to make many long calculations automatically and print out the results.  A working model was built in 1822 and fabrication began in

Gash 2

1823.  Babbage works on his invention for 10 years when he lost interest in it. His loss of interest was caused by a new idea he thought up.  The Difference Engine was limited in adaptability as well as applicability.  The new idea would be a general purpose, automatic mechanical digital computer that would be fully program controlled.  He called this the Analytical Engine.  It would have Conditional Control Transfer Capability so that commands could be inputted in any order, not just the way that it had been programmed.  The machine was supposed to use punch cards which were to be read into the machine from several reading stations.  The machine was supposed to operate automatically by steam power and only require one person there to operate it.  Babbages machines were never completed for reasons such as, non-precise machining techniques, the interest of few people and the steam power required for the devices was not readily available.

The next advance in computing came from Herman Hollerith and James Powers.  They made devices that were able to read cards that information had been punched into, automatically.  This advance was a huge step, because it provided memory storage capability.  Companies such as IBM and Remington made improved versions of the machine that lasted for over fifty years.

ENIAC which was thought up in 1942, was in use from 1946 to 1955.  Thought up by J. Presper Eckert and his associates.  The computer was the first high-speed digital computer and was one thousand times faster than its predecessor, the relay computers.  ENIAC was very bulky, taking up 1,800 square feet on the floor and having 18,000 vacuum tubes.  It was also very limited in programmability, but it was very efficient in the programs that it had been designed for.

In 1945 John von Neumann along with the University of Pennsylvania came up with what is known as the stored-program technique.  Also due to the increasing speed of the computer subroutines needed to be repeated so that the computer could be kept busy.  It

Gash 3 would also be better if instructions to the computer could be changed during a compution so that there would be a different outcome in the compution.  Neumann fulfilled these needs by creating a command that is called a conditional control transfer.  The conditional control transfer allows for program sequences to be started and stopped at any time.  Instruction programs were also stored together so that they can be arithmetically changed just like data.  This generation of computers included ones using RAM, as well as the first commercially available computers, EDVAC and UNIVAC.  These computers used punched-card or punched tape reading devices.  Also some of the later ones were only about the size of a grand piano and contained 2,500 electron tubes, which was much smaller than ENIAC.

During the fifties and sixties the two most important advances were magnetic core memory and the transistor.  These discoveries increased RAM sizes from 8,000 to 64,000 words in commercially available computers.  The first supercomputers were made with this new technology.  During this period successful commercial computers were made by Burroughs, IBM, Sperry-Rand, Honeywell and Control Data.  These computers could now have printers, disk storage, tape storage, stored programs and memory operating systems.  These computers were usually owned by industry, government and private laboratories.

The next advance came in the form of a chip.  Transistors and vacuum tubes created vast amounts of heat and this damaged the delicate internal parts of the computer.  The heat problem was eliminated through quartz.  The integrated circuit made in 1958 consisted of three components placed on a silicon disc that was made of quartz.  As technology advanced more and more components were fit onto indiviual chips and this resulted in smaller and smaller computers.  There was also an operating system created during this stage that allowed for many programs to be run at once, with one central program that had the ability to monitor and coordinate computer memory.
