2600: The Hacker Quarterly Data mining Process of extracting and discovering patterns in large data sets Data mining is the process of extracting and discovering patterns in large data sets involving methods at the intersection of machine learning, statistics, and database systems.[1] Data mining is an interdisciplinary subfield of computer science and statistics with an overall goal of extracting information (with intelligent methods) from a data set and transforming the information into a comprehensible structure for further use.[1][2][3][4] Data mining is the analysis step of the "knowledge discovery in databases" process, or KDD.[5] Aside from the raw analysis step, it also involves database and data management aspects, data pre-processing, model and inference considerations, interestingness metrics, complexity considerations, post-processing of discovered structures, visualization, and online updating.[1] Etymology[edit] Background[edit] The manual extraction of patterns from data has occurred for centuries. Process[edit]
Anonymous (group) Anonymous (used as a mass noun) is a loosely associated international network of activist and hacktivist entities. A website nominally associated with the group describes it as "an internet gathering" with "a very loose and decentralized command structure that operates on ideas rather than directives". The group became known for a series of well-publicized publicity stunts and distributed denial-of-service (DDoS) attacks on government, religious, and corporate websites. Anonymous originated in 2003 on the imageboard 4chan, representing the concept of many online and offline community users simultaneously existing as an anarchic, digitized global brain.[3][4] Anonymous members (known as "Anons") can be distinguished in public by the wearing of stylised Guy Fawkes masks.[5] In its early form, the concept was adopted by a decentralized online community acting anonymously in a coordinated manner, usually toward a loosely self-agreed goal, and primarily focused on entertainment, or "lulz".
How To Understand Programs for Password Hacking | How To Do Things Password hacking may sound like an ominous thing to most people, who also believe that someone who may know how to do it can't possibly be up to any good. On the contrary, it can actually be most useful for you or potential clients. You wouldn't know when you would need to hack your own email account in case you forgot your password, or an important client needs your help to crack a program password. Dictionary attacks. Password hacking is still a skill that not everyone can do. Research and development Cycle of research and development The research and development (R&D, also called research and technical development or research and technological development, RTD in Europe) is a specific group of activities within a business. The activities that are classified as R&D differ from company to company, but there are two primary models. In one model, the primary function of an R&D group is to develop new products; in the other model, the primary function of an R&D group is to discover and create new knowledge about scientific and technological topics for the purpose of uncovering and enabling development of valuable new products, processes, and services. Under both models, R&D differs from the vast majority of a company's activities which are intended to yield nearly immediate profit or immediate improvements in operations and involve little uncertainty as to the return on investment (ROI). Background[edit] Business[edit] Present-day R&D is a core part of the modern business world.
Chaos Computer Club The CCC describes itself as "a galactic community of life forms, independent of age, sex, race or societal orientation, which strives across borders for freedom of information...." In general, the CCC advocates more transparency in government, freedom of information, and the human right to communication. Supporting the principles of the hacker ethic, the club also fights for free universal access to computers and technological infrastructure.[2] History[edit] The CCC was founded in Berlin on September 12, 1981 at a table which had previously belonged to the Kommune 1 in the rooms of the newspaper die tageszeitung by Wau Holland and others in anticipation of the prominent role that information technology would play in the way people live and communicate. The CCC became world famous when they drew public attention to the security flaws of the German Bildschirmtext computer network by causing it to debit DM 134,000 in a Hamburg bank in favor of the club.

Master Foo and the Ten Thousand Lines Master Foo once said to a visiting programmer: “There is more Unix-nature in one line of shell script than there is in ten thousand lines of C.” The programmer, who was very proud of his mastery of C, said: “How can this be? C is the language in which the very kernel of Unix is implemented!” Master Foo replied: “That is so. Nevertheless, there is more Unix-nature in one line of shell script than there is in ten thousand lines of C.” The programmer grew distressed. Master Foo replied: “All that you say is true. The programmer scoffed at Master Foo and rose to depart. The programmer muttered through his beard, contemplating what Nubi had written. “And how many hours would you require to implement and debug that C program?” “Many,” admitted the visiting programmer. “And who better understands the Unix-nature?” Upon hearing this, the programmer was enlightened.
Penetration test Method of evaluating computer and network security by simulating a cyber attack A penetration test, colloquially known as a pen test or ethical hacking, is an authorized simulated cyberattack on a computer system, performed to evaluate the security of the system;[1][2] this is not to be confused with a vulnerability assessment.[3] The test is performed to identify weaknesses (also referred to as vulnerabilities), including the potential for unauthorized parties to gain access to the system's features and data,[4][5] as well as strengths,[6] enabling a full risk assessment to be completed. Security issues that the penetration test uncovers should be reported to the system owner.[9] Penetration test reports may also assess potential impacts to the organization and suggest countermeasures to reduce the risk.[9] Penetration tests are a component of a full security audit. Several standard frameworks and methodologies exist for conducting penetration tests. History[edit] Tools[edit] Payload[edit]
Choose Your Neighborhood 1 Pick Your Neighborhood 2 Introduce Yourself 3 Meet Your Neighbors Why isn’t my neighborhood showing up? We are constantly working to expand and improve our list of neighborhoods, but there are still some neighborhoods we don’t know about. Why are you calling my city/town/village/hamlet/commune a “neighborhood”? The word “neighborhood” means different things to different people, and a lot of that depends on where you live. I don’t live in the US. Blockboard is currently only available in the US, but we plan to expand to cover other countries soon! neighborhood data from Zillow and Geonames
How To Ask Questions The Smart Way In the world of hackers, the kind of answers you get to your technical questions depends as much on the way you ask the questions as on the difficulty of developing the answer. This guide will teach you how to ask questions in a way more likely to get you a satisfactory answer. Now that use of open source has become widespread, you can often get as good answers from other, more experienced users as from hackers. The first thing to understand is that hackers actually like hard problems and good, thought-provoking questions about them. Despite this, hackers have a reputation for meeting simple questions with what looks like hostility or arrogance. What we are, unapologetically, is hostile to people who seem to be unwilling to think or to do their own homework before asking questions. We realize that there are many people who just want to use the software we write, and who have no interest in learning technical details. We're (largely) volunteers. (Improvements to this guide are welcome.
Kali Linux Kali Linux is a Debian-derived Linux distribution designed for digital forensics and penetration testing. It is maintained and funded by Offensive Security Ltd. It was developed by Mati Aharoni and Devon Kearns of Offensive Security through the rewrite of BackTrack, their previous forensics Linux distribution.[1] Kali Linux is distributed in 32- and 64-bit images for use on hosts based on the x86 instruction set, and as an image for the ARM architecture for use on the Raspberry Pi computer and on Samsung's ARM Chromebook.[3] References[edit] External links[edit]
