Steve Jobs

The company has produced thousands of computers that have found their place in the universities. According to legend, in 1979, Steve Jobs visited the Xerox Research Center in Palo Alto, and then many of the features of the Alto were embodied in "apple" computers, Lisa and Mac. Soon realized the mistake at Xerox and the company began to promote the graphics workstation, Xerox Star, which was based on technology developed for the Alto. But to say that it was too late – to say nothing. Next: Five more annoying bugs, including the history of Napster, CompuServe, and Craigslist.

6. The record industry is on nakatannomu Perhaps no other industry like the music, you can not count so many missed opportunities. In 1999, Shawn Fanning file sharing (Shawn Fanning) Napster opened the world of people is incredibly easy to share music in real time. Record companies immediately filed for Napster to court for complicity in copyright infringement. Then CEO Hank Barry of Napster (Hank Barry) asked representatives of the music industry with a proposal to distribute the music in its network on the basis of radio – and to pay performers' fees. This appeal was never heard.

Napster users quickly migrated to other P2P-networks (such as Gnutella and Grokster), and music "pirates" have become the main enemy of the RIAA. In 2000, the site MP3.com has launched a service allowing users to upload songs from the CD-personal collections and distribute them to any other user. Record companies have filed for service to the court for aiding in copyright infringement and won in the end.

Revolution Media

The colaborativo journalism is a step given in this direction. David Weinberger, author of the book ' The new clutter digital' my cites examples in this direction as the Oh news and the Wikipedia. Both situations where the common citizen can add knowledge and information, leaving of being a passive consumer to also become a content producer. These and other changes in them place each time next to the onipresena. Zygmount Bauman already says in it in its book ' Lquida&#039 modernity;. Bauman speaks in the onipresena of the information, the culture and the knowledge.

In a world the societies leave its solid, immovable status, pass to assume the fluidity of the liquid, that adapta it the situations, molding itself it the way. Thus, in this context we must adapting in them to these changes. to assume our role as contributing and collaborating in the construction of the New World-wide Order. As already it showed one of the videos most famous of the Youtube. The Revolution Media. The birth of prossumer. A communion between the producer and content consumer. The mobile Internet and devices are half platforms and of the moment.

However the transformation goes beyond the technology. It is mental, psychological and spiritual. Today, as well as the information, through the communication devices, we obtain to be gifts in more than a place at the same time. We obtain to multiply the access our ideas. Our vision of the world. As well as also, of another side, we can have access other universes. Either of house, through the television, of the radio or the Internet. Or in the street through one smart phone, net book or palm. everything this does not scare me impresses nor me, therefore already alive in this reality. As well as others as much. It is joined we. We are waiting you.

Stack is one of the structures of data, where its basic idea is that all the access to its elements is made from the top. In this manner, when a new element is introduced in the stack it starts to be the element of the top, as well as all the removal of the stack is initiated solely for the top. The elements of the stack alone can be removed in the inverse order to the order where they had been introduced: the first one that it leaves finishes is it that it entered (to describe this strategy acronym LIFO is used – last in, first out). The stack is composed for five operations that disponibilizam the manipulation and the access to the information of the same one. The operations are: to create, to insert, to verify, to remove to eliberar. The operation to create stack consists basically of inicializar it as NULL, that it means null. It is important to remember that for each bred stack its inicializao is essential, therefore this null element has the function to inform the end of its stack.

The function to insert, objective to pile up a new element in the top, for in such a way is necessary that a space is placed in the memory and that, of preference, either a dynamic allocation, therefore thus you will only use the amount of memory that really necessary. The function to verify, aims at to inquire if the stack is empty. The operation to remove, unpiles an element of the top, that is, it removes the top of its stack. finishes it operation is to liberate the used memory for the use of the stack, generally is made with the function free (). The structure of data (stack) widely is used in elaboration of programs and, an example of known use of stack more is the proper stack of execution of language C. The local 0 variable of the functions are made use in a stack and a function alone has access the 0 variable of the function that is in the top, not being able to have access the local 0 variable of other functions.

Choice Tips

You have decided to replace old water pipes to the new? But wondering what material in favor of making a choice. Consider the advantages and disadvantages of tubes of the most common modern materials: plastic, copper, polypropylene. Metal pipes. in general form metal-tube are three-layer structure: the main pipe of cross-linked polyethylene (modified polyethylene with closed spatial molecular structure) is a good heat resistance (the maximum long-term operating temperature – 95 . C, maximum short-term – 110 C for several hours) is chemically neutral, harmless, long-lasting ability to withstand high pressure (working pressure of 10 atm.) Thermal expansion coefficient = 0.02 (mm / m * K) Metal pipes scope quite extensive – cold, hot water, central heating, heated floors. Disadvantages: range of diameters from 16 to 40 mm. Polypropylene tubes. Cyrem for PP pipes is a copolymer poliproplen-random bit of thermoplastics.

durability (according to all standards of construction is 50 years) low thermal conductivity of high temperature resistance (in Depending on the thickness – up to 75 C), the ability to withstand short-term temperature rise of up to 95 media. C, the absence of the electrical conductivity of chemically vopriimchiv to many aggressive media, eco-friendly easily washed out during operation, maintaining the hygienic properties during its useful life, which according to all standards of construction is 50 years. produce three types of pipes with a wall of varying thickness, designed for working pressure of 10, 16, 20 atm. reinforced polypropylene with improved thermal properties, allows for flexible and targeted use of the pipe – not overpaying, and with maximum efficiency. (K p = 0.062), reduced deformation temperature (one meter lengthened by 0.026 mm), increases the strength of the tube Disadvantages: The high coefficient of thermal expansion = 0.15 Copper pipe high resistance to corrosion Copper has a low roughness coefficient – 0.01 mm is not afraid of high temperatures.

The melting point of copper – 1083 S. There is no problem to use copper for the heating schedule of 95/70. She is not afraid of high pressures. Working pressure depends on the type of copper pipe diameter and wall thickness, for example, for not annealed tube 15h1 pressure – 85 atm. and for the annealed – 50 atm. linear expansion coefficient = 0.017 (mm / m * K) is not permeable to oxygen, leading to corrosion of radiators, valves especially when high temperatures. Copper has antibacterial properties, is environmentally friendly. Disadvantages: The price of the material, not much, but higher. According p.10.1 SNP April 2 01-85 mandatory use of steel pipes in water supply system is preservation of the inner and outer protective antirust layer. In most cases, connections are made by welding, which leads to the destruction of the inner and outer layer antirust. Consequently, the use of traditional technologies mounting steel pipe leads to a violation of regulatory requirements. Mistakenly believe! that the replacement radiators for modern materials will be less reliable due to the threaded connection (switching to a combined coupling), because Screwed imagine the most vulnerable point in the system. But do not wind onto the valves on the thread? Thread on the valves is no different from any thread on the adapter. (SNIP April 2 05 – 91 "steel and plastic pipes, when used in heating systems is equivalent to a technical decision") Be careful! Poor quality material, unskilled spetsialistyprivedut you to re-replacement or repair of the system, causing material damage

By God

Children and grandchildren are not initiated into the mystery of origin. They lived, not knowing that belong to another god and another people. Outwardly, nothing different from other people, they still had one more feature. By God's will present the feeling of love and affection they can experience only to the person from their tribe. And they had for a long time to find their half. Often they helped in the monks, pilgrims, wandering around the cities. They could easily distinguish among the crowd of his fellow tribesman from other people.

Their sacred duty was to help young people of his people to find each other. But marriage not always made in heaven. Those who could not get my half, are not forever remain bachelors and old maids. That's only children born of such marriages already lost part of innate abilities, which had the monks. Passed the century. The desert and its secrets guarded by monks, and beyond developed civilization and technological progress. People have tried using the machines to subdue the elements of nature, and the priests have long Narfeya ruled that the element with the thought.

The monks knew everything that happens in the world and not only because of the sacred mirror. In order to become a full priest of the temple, the monk was obliged to make a pilgrimage to all major cities in the world. At times it takes many years, but that means time for a priest of the god, who argues that this value is also relative. When the sky began to appear the first aircraft to lift Sabur air dust storms, obscuring the monasteries from prying eyes. But planes are becoming more and they began to fly higher. And then the archbishop covered oases, mirages domes, creating the illusion of wilderness. People have always tried to cross and to conquer the wilderness, but Sabur suppressed all attempts to sharply and severely, making it clear that this area is impassable and dangerous. After each lesson a long time people leave the desert alone. In border areas, the Archbishop of people do not touched until they approached the forbidden line.

Why Do I Need A Computer ?

What is the modern world? The modern world is the era of computer technology, greatly expanding and highly progressive. Nowadays computers are closely into our lives and help us solve many problems, in particular access to the Internet has given us an opportunity to gather a huge audience of people who are able to share experiences among themselves. In this regard, computers today are closely intruded into our lives, work and age paper-based information have gone to the well-forgotten past. For different people the computer can represent different interests. According to various statistics, we can determine why your computer is for certain people. I would like to note some of the most important of them: The computer as a tool for relaxation and entertainment.

Well, I think everybody understands that the computer can serve us as an expensive toy that allows us to head to leave the virtual world. What is the benefit in this case, we can bring this "television" with the buttons? Working on the computer, people can relieve fatigue and stress, obtained in the real world. It can replace us and the tv, watching videos, television programs and music, listening to music, radio, acts as a means of viewing photos, and more. etc. Also, speaking of entertainment, we can not say about the games, which have now become almost real reality.

Significantly expands the scope of entertainment when the computer is connected to the Internet. In the Internet you can find free software for your computer and download it. Computer to work. This point I would like to split into two parts: 1. Computer for work online, 2. Computer to work offline. In the first case, the work is fully connected with the connection to the Internet. We can choose the ways of generating income, existing today, that we love. Through the Internet you can look for work, do work to order and get paid to learn and earn in a particular direction (for example, you can learn how to make your site a bad thing make the creation and promotion of a website). One word to us online opens the door to financial independence. Three times that for the work is that all the office work you can just bring home and carry her home in comfortable atmosphere. Internet connection is not required. What here can be attributed specifically – is to work with office applications and text editors, is to work with graphics and video applications, it is also working with audio applications, and more. Computer as a communication tool. Today, the computer serves as a means of communication: Email Internet-pager (through special programs, such as Icq, with that message comes anywhere in the world in seconds) Phone, allows you to talk on the phone at a lower price, you can video conference when the conversation is with your camcorder. And Finally, special sites allow to leave messages, comments (forums, blogs, message boards, online diaries) In conclusion I would like to note that the pc is a remarkable creation of man, by means of which mankind has greatly accelerated the pace of growth and production. This machine performs a huge number of operations per unit time, which is not manageable, neither man nor what else exists on this planet. Internet, with the help of modern technology has given people the ability to communicate, work, study and rest. In short, life without a computer is simply not conceivable.

Winter Tires – Features And Options

Universal winter tires on all occasions, unfortunately, it's fantastic. However, this is not a lack of buses, but only limitations possibilities of designs and materials, and, besides, an extra argument in favor of timely seasonal replacement tires. After all, if not winter tires are universal, then what about all-season models, and even more so – about summer (year-round operated) tires. When choosing tires for the winter, First of all, note to any road surface in the first place they will be used. Tires for urban roads – is one thing, winter tires for Proselkov – it's a different story. Non-studded winter bus divided into two types – the European and Scandinavian. Tire tread pattern is similar to the European figure protivodozhdevyh tires – to build a diagonal extensive network of drainage canals, an abundance of fine cuts, strong lugs.

This type of tires are designed to ensure safe movement of the wet – after the rain, wet snow – cover. For many motorists one of the defining characteristics for Tyre choice is their price – and located it in close association brand tires. Tyre marks can be divided into three categories – authoritative, affordable, low cost. Tyres, belonging to the first category, the most expensive, but it allows the manufacturer to use when creating the newest technologies. The latter is cheaper, and they have an acceptable quality for most car owners. Tires third category inexpensive, have an acceptable quality and in our country the most popular.

Cache Memory

The cache memory of the first and second level. In all 486 have an integrated "first-tier cache controller with of 8 or 16 Kbytes. Cache – a high-speed memory, designed for temporary storage code and data. Circulation to the integrated cache occur without wait states, as its performance capabilities suited processor. Through this exchange of information with relatively slow system memory accelerates with authority. The processor does not need to wait for another piece of code or data will come from the main memory area, and this leads to a noticeable increase in the productivity of companies. When lack of cache, such a pause would appear quite frequently. In coming up with an integrated cache, the cpu time is even more central role, as it is often the only type of memory throughout the system, which can work synchronously with the processor.

In a variety of walking up to date processor clock frequency multiplier is used, so they operate at a frequency in a couple of times the system clock frequency board is connected to these processors. For example, the clock frequency of the "333 MHz" is running on a processor Pentium ii, a 5-times have superior clock speed of the motherboard, the same 66 MHz. Since memory is connected to system board, it also can operate only at speeds not exceeding 66 MHz. In such a system from all types of memory integrated cache can only operate at a clock frequency of 333 MHz. Inspected in this sample processor Pentium ii 333 MHz on-chip cache, a total of 32 kb "a 2-separate blocks of 16 kb. If the required data in an integrated cache available, the processor asks for them in the cache memory of the second level or specific to system bus.

In systems Pentium P5 cache in the second level is set on the motherboard and runs at the system board. In the P6 family processors cache second level is set to the processor. In and Celeron processors Heop cache second level operates at a frequency of the processor. The unique Pentium ii processor cache in the second level is working at half the processor frequency.

Medium Tank

Commander's tank was developed in 1954 and adopted by the adopted in 1958, he differed from the tank by the presence of a linear short-wave radios additional P-112 and benzoelektricheskogo charger unit for power consumers in the long-term operation in the parking lot. Exchange machine-gun sgmt has been saved. With the use of components and assemblies of the T-54 were developed and mass-produced self-propelled SU-122 and ZSU-57-2, launched bridge mtu bronetyagach BPS-2 and self-propelled crane SEC-12d. Some of the tanks has been fitted for mounting mine roller-trawl PT-54 tank btu bulldozer, snowplow tsa and individual craft PST-54. T-54 tank had two versions – T-54A and T-54B. Export T-54 and its modifications carried out in 39 countries. Medium Tank T-54A Medium Tank T-54A was developed in Tagil design bureau under the leadership of ln Kartseva and adopted in the 1955 serial production was carried out from 1955 to 1957 in , Tagil and Omsk. For the first time Soviet tank manufacturing in a production tank gun mounted D-10TG with stabilizer in the vertical plane of the STF-1 'Horizon' and eductor for purging the barrel of gunpowder gases after the shot. These technical solutions served as the beginning of a great work of designers in this field and at the end of the first postwar period, all tanks were held at the Soviet Army, had a two-plane gun stabilizer for aimed Shooting on the move and the kicker is to reduce the gas content of the fighting compartment. Propulsion appeared stage air cleaner and radiator shutter controlled to maintain optimal engine operation.
