# Learn about a few simple DOS function calls

## ALGORITHMS PHẦN 6 PDF

The first of these is a fundamental cryptographic property, the second two provide the security, and the fourth makes the system feasible for use. This general scheme was outlined by W. Diffie and M. Hellman in 1976, but they had no method which satisfied all of these properties. Such a method was discovered soon afterwards by R. Rivest, A. Shamir, and L. Adleman. Their scheme, which has come to be known as the RSA public- key cryptosystem, is based on arithmetic algorithms performed on very large integers. The encryption key P is the integer pair (N,p) and the decryption key S is the integer pair (N,s), where s is kept secret. These numbers are intended to be very large (typically, N might be 200 digits and p and s might be 100 digits). The encryption and decryption methods are then simple: first the message is broken up into numbers less than N (for example, by taking lg N bits at a time from the binary string corresponding to the character encoding of the message). Then these numbers are independently raised to a power modulo N: to encrypt a (piece of a) message M, compute C = P(M) = MPmod N, and to decrypt a ciphertext C, compute M = S(C) = C”mod N. This computation can be quickly and easily performed by modifying the elementary exponentiation algorithm that we studied in Chapter 4 to take the remainder when divided by N after each multiplication. (No more than 2 log N such operations are required for each piece of the message, so the tot,al number of operations (on 100 digit numbers!) required is linear in the number of bits in the message.)

If you have a table that already has running totals, you can calculate the differences between pairs of successive rows. Listing 15.3 backs out the intercity distances from the fol- lowing table, named roadtrip , which con- tains the cumulative distances for each leg of a trip from Seattle, Washington, to San Diego, California. See Figure 15.3 for the result.

II. Read the passage below and choose one best answer A, B, C or D to each question. Another effect of air pollution is acid rain. The phenomenon occurs when sulphur dioxide and nitrogen oxides from the burning of fossil fuels such as petrol, diesel, and coal combine with water vapour in the atmosphere and fall as rain, snow or fog. These gases can also be emitted from natural sources like volcanoes. Acid rain causes extensive damage to water,forest and even human health. Many lakes and streams have been contaminated and this has led to the disappearance of some species of fish in Europe, USA . Because the contaminants are carried long distances, the sources of acid rain are difficult to pinpoint and hence difficult to control.

## BEGINNING DATABASE DESIGN P18 DOC

❑ The COMPANY_URL and COMPANY fields are added to the SELLER table. The inclusion of the term COMPANY in the name of the field is intentional. This implies that only bona fide company or corporate level traders should be allowed to enter company names or URLs (or both fields). Thus only sellers trading as online retailers (even competing online auctioneers) are ultimately encouraged to list themselves as full-fledged going concerns. This allows the online auction house in the case study example to become not only an auctioneer for the individual, but also a well-publicized portal to the Internet, for other auctioneers. The Internet has huge market potential. An online auction house with a well-established market presence (in the minds of potential Internet buyers) is extremely valuable for other retailers — an obvious source of prof- itability for the online auction house of this case study.

Resistance in electronics is a lot like friction in mechanical systems: it puts the brakes on electrons (those teeny-tiny moving particles that make up elec- trical current, or electricity) as they move through materials. In this chapter, you find out exactly what resistance is, where you can find resistance (everywhere) and how you can use it to your advantage by select- ing resistors (controlled amounts of resistance) for your electronic circuits. You explore the intimate relationship between voltage (the electrical force that pushes electrons) and current in components that have resistance, which is summed up quite nicely in a very simple equation with an authorita- tive name: Ohm’s Law. We put Ohm’s Law to work in analysing the goings-on in some basic circuits. Finally, you look at the role of Ohm’s Law and related power calculations in the design of electronic circuits.

Air pollution is a serious problem in many cities. Motor vehicles, factories and other sources create so much air pollution that it may hang in the air like dirty fog. Air pollution threatens the health of the people who live in cities. City wastes cause water pollution when they are poured into the waterways. These wastes kill fish and make some areas unfit for swimming. In addition, many large cities have difficulties in disposing of their garbage. The amount of garbage grows each year, but places to put it are quickly filling up. Citizens, governments, industries, scientists, and business people must work together in different ways to gradually reduce pollution. For example, most cities have introduced recycling programmes. 1. Motor vehicles and factories are among some sources of air pollution.

## Remoting

Spring WS allows for and encourages the use of “top-down” SOAP design. The user specifies an XML schema description for the methods that he will be exporting, and then creates corresponding service description files, interfaces, and services to support them. This all requires a very good understanding of SOAP—more than I think is appropriate for a beginners text; we will focus purely on the use of the JAX-RPC libraries because this has the most in common with the other remoting technologies that we have considered in this chapter. Note that I do not propose to teach you how to use even JAX-RPC in this chapter because the subject matter is far too complex—only how to integrate it with the Spring framework.

Categorical data is data that records categories. Examples could be, a survey that records whether a person is for or against a proposition. Or, a police force might keep track of the race of the individuals they pull over on the highway. The U.S. census (http://www.census.gov), which takes place every 10 years, asks several different questions of a categorical nature. Again, there was one on race which in the year 2000 included 15 categories with write-in space for 3 more for this variable (you could mark yourself as multi-racial). Another example, might be a doctor’s chart which records data on a patient. The gender or the history of illnesses might be treated as categories. Continuing the doctor example, the age of a person and their weight are numeric quantities. The age is a discrete numeric quantity (typically) and the weight as well (most people don’t say they are 4.673 years old). These numbers are usually reported as integers. If one really needed to know precisely, then they could in theory take on a continuum of values, and we would consider them to be continuous. Why the distinction? In data sets, and some tests it is important to know if the data can have ties (two or more data points with the same value). For discrete data it is true, for continuous data, it is generally not true that there can be ties.

## POSTGRESQL SERVER PROGRAMMING

Since you are still reading this, I'm sure that you're a whole lot more like me. I spend about 10 percent of my time writing new code, and about 90 percent of it editing the mistakes and oversights that I (and others) made in the first 10 percent. In fact, it could be argued that no new code is ever written at all. Actually, a more accurate description of the process is that a dumb assertion is made, and then edited until the customer can no longer stand the Quality Assurance (QA) process. We then ship the result in the hopes of being useful to the end user. Was that too much reality for you? Sorry. The objective of this chapter is to make you much faster at making mistakes. As a by-product, you will also learn how to diagnose and fix them at an alarming rate of speed. The net effect for which we are hoping is that your boss will assume you wrote it correctly the first time. This is, of course, a lie, but a very useful one. This concept is critical to agile software development. In that philosophy, it is called "prototyping". The idea is to create a feature quickly and demonstrate it as a conversation point, rather than trying to produce an entire system (presumably perfectly) from conceptual documentation. Other authors refer to it as "failing quickly ". It is a recognition that the first 3 or 4 development iterations will probably not be acceptable to the customer, and shouldn't be advertised as final until some discussion has occurred.

## FOUNDATIONS OF PYTHON NETWORK PROGRAMMING 2ND EDITION PHẦN 3 DOCX

The third field in the socket() call, the protocol , is rarely used because once you have specified the address family and socket type, you have narrowed down the possible protocols to one major option. For this reason, programmers usually leave this unspecified or provide the value zero to force it to be chosen automatically. If you want a stream under IP, the system knows to choose TCP; if you want datagrams, then it selects UDP. That is why none of our socket() calls in this book has a third argument: it is in practice almost never needed. Look inside the socket module for names starting with IPPROTO for some examples of protocols defined for the AF_INET family; listed there you will see the two this book actually addresses, under the names IPPROTO_TCP and IPPROTO_UDP .

________ then ? V. Read the passage carefully and write the answers ( from 36 to 40 ) The ancient Egyptians firmly believed in the afterlife and spent their time on earth preparing for it. Elaborate burial rituals included preparing the burial site, providing for all of the deceased’s material needs ( food, clothing, jewels and tools of their trade), and preserving the corpse so that it would not decay. This preservation was accomplished through a process of communification. The ancients left no written accounts as to execution of this process, so scientists have had to examine mummies and established their own theories. The embalming process might have taken up to seventy days for the pharaohs and nobility and only a few days for the poor. 36. How have we been able to learn about the mummification process.
