What exactly is IQ?

Depending on whom you ask. Many people even know that a clinical psychologist in addition to the measurement of cognitive abilities is the first widely accepted that developed the French psychologist, Binet, when he was tasked with improving government services to school children who have developmental disorders. Lewis Terman of Stanford fix it, and creates what is called the Stanford-Binet, which when you are old enough now, once you get when you enter vocational school. There are also other types such as the Wechsler tests, for example, WAIS-IV for adults and WISC-IV for children.

At present, Charles Spearman, one of the great figures of psychology, found that when we give certain kinds of intelligence tests - for example to design a building design or solve a problem of logic - the score is different, but strongly correlated with each other. The conclusion is that there is a major factor behind these tests, with a minor factor in the set top score slightly higher or lower - the main factor is called g, or "general intelligence (general). The idea of g is still used today. IQ test score is given to us; g is the hidden construction which we can not measure directly. He is partly reflected in IQ scores. The purpose of clinical and cognitive psychologists in designing an IQ test right now is close to g as closely as possible.

For most psychologists, see g as looking at pornography. You know it's porn, but you can not define it. David Wechler attempted to define, according to g is a "global or aggregate capacity of individuals to act on purpose, to think rationally and effectively cope with their environment." It is the ability of your reasoning tools to adapt to the environment, or the kind of environment that may exist.

In the study of intelligence, no such thing as Flynn Effect. Dr. Flynn discovered that IQ increased an average of 30 points every 100 years. We are more intelligent in some things than our grandparents.

This increase is clearly too high if only because of genetics. Grandparents we have a gene similar to us. Therefore, 30-point IQ difference is due to the environment and learning.

Dr. Flynn explains this difference is a difference in learning abstract thinking. Our ancestors lived on Earth as a practical person who had to concentrate on concrete issues, problems of everyday life. IQ tests are tests that abstract. Now, we are taught to think abstractly. As a result, our IQ test score increases.

Abstract thinking is thinking in a logical generalization and abstraction, while the concrete thinking is to think straight (literally) and bound to the impression of the senses at that time.


This is the video related to sql injection

What is really sql injection?
And what is the relationship to the hacking?..Here it is..

SQL injection is an attack in which malicious code is inserted into strings that are later passed to an instance of SQL Server for parsing and execution. Any procedure that constructs SQL statements should be reviewed for injection vulnerabilities because SQL Server will execute all syntactically valid queries that it receives. Even parameterized data can be manipulated by a skilled and determined attacker.

The primary form of SQL injection consists of direct insertion of code into user-input variables that are concatenated with SQL commands and executed. A less direct attack injects malicious code into strings that are destined for storage in a table or as metadata. When the stored strings are subsequently concatenated into a dynamic SQL command, the malicious code is executed.

The injection process works by prematurely terminating a text string and appending a new command. Because the inserted command may have additional strings appended to it before it is executed, the malefactor terminates the injected string with a comment mark "--". Subsequent text is ignored at execution time.

The following script shows a simple SQL injection. The script builds an SQL query by concatenating hard-coded strings together with a string entered by the user:
