Lying. The word "lying" is a present participle of the word "lie," which is a verb meaning to intentionally provide fallacious facets, or a noun meaning an erroneous utterance.

Throughout the ages, man has been fascinated by lies and deceit, through the falsification of manuscripts, coins and data, and the distortion of images. The poems, ideas, inventions, and books have not been handed over from misrepresentation and plagiarism not only in our time but over the preceding centuries. Through e-mail, thousands of victims are signed daily! Lying has become a widespread social scourge at present. I read

Today, people generate knowledge through different outlets that can be classified according to its nature. Such as ones desire to look deeper can help an individual obtain new knowledge and ideas through their expanded imagination. Or even ones psychological responses such as their emotions can produce information without the originator knowing. It all starts with inquiry and how a certain situation came to be. Pamela Meyer from Ted Talks decided to discuss on how to spot a liar. Now this may seem

network security tools was the intrusion detection system (IDS), first developed by SRI International in 1984. An IDS provides real-time detection of certain types of attacks while they are in progress. This detection allows network professionals to more quickly mitigate the negative impact of these attacks on network devices and users. In the late 1990s, the intrusion prevention system or sensor (IPS) began to replace the IDS solution. IPS devices enable the detection of malicious activity and have the

to detect a variety of attacks and probes, such as buffer overflows, stealth port scans, CGI attacks, OS fingerprinting attempts, and much more. Snort uses a flexible rules language to describe traffic that it should collect or pass, as well as a detection engine that utilizes a modular plug-in architecture. Snort has a real-time alerting capability as well, with alerts being sent to syslog, a separate “alert” file or even Windows computer

prescribing the logic of discovery39. Lakatos believes that one counterexample falsifies the whole theory is too naïve and that a scientific theory is a program rather than an individual claim3. Lakatos subsequently proposed “progressive research programme”3 to address these issues. To handle counterexamples, he prescribed the “sophisticated falsificationism”, which is used in developing the ESS theory as mentioned above. Nevertheless, there is a consensus that falsifiability is a desirable characteristic

1. ITMO 540 HOMEWORK 3 Name: Payal Desai CWID: A20362549 REVIEW QUESTIONS: Answer 1: White noise is the static noise that is heard in the background. Some amount of it is always present but too much of white noise does not enable a clear conversation because we lose the signal. Answer 2: Impulsive noise is the one which occurs discretely. Unlike white noise, it is not continuous and hence becomes difficult to interpret because it occurs at random moments. This also makes it more disruptive

Rene Descartes’ view on the mind-body problem is one that is much debated even today, nearly four centuries since his demise. To discuss the mind-body problem, we must first establish the definitions of mind and body, and how Descartes came upon these definitions. Following that, we can then discuss the validity of his views, and some of the criticisms his views have received. To explain how Descartes arrived at his views of the mind and body, we must look into his process of systematic doubt.

“World is not designed by science, but by art in spite of some pretence and humbug to the contrary. I do not mean to suggest that engineering can do without science, on the contrary, it stands on scientific foundations, but there is a big gap between scientific research and the engineering product which has to be bridged by the art of the engineer” I still remember the day I witnessed the scaled models of famous civil structures in the annual science and technology festival of Indian Institute of

their time. During and after the revolutions everything was still being figured out and settled so I feel they were just sort of predicting what could happen in the future at that point. Emile Durkheim’s Structural Functionalism theory also known as the functionalist theory viewed society as a bunch of structures or parts that when put together could form a bit of solidarity. Each “part” or institution plays a different role in society which is still true to this day. If we did not have our school
