Multi-factor authentication (MFA) fatigue attack is a type of cyber attack where an attacker overloads a target with authentication requests to a system that employs MFA. The goal is to cause the user to become overwhelmed or fatigued by the constant requests, leading them to approve a request out of frustration or misunderstanding, potentially granting the attacker access to their account or system.

Operations Security (OPSEC) is a risk management process that seeks to protect sensitive information from adversaries by identifying critical information, analyzing threats, and implementing countermeasures. The primary goal of OPSEC is to prevent unauthorized access to information that could potentially be used against an organization, particularly in military, government, and corporate environments. The OPSEC process typically involves the following steps: 1. **Identifying Critical Information**: Determining what information is vital to the organization's success and needs protection.

A security hacker, often referred to simply as a "hacker," is an individual who uses technical skills to manipulate or exploit computer systems and networks. The motivations, methods, and ethical considerations of hackers can vary widely, and they are generally categorized into several types: 1. **White Hat Hackers**: These are ethical hackers who use their skills to help organizations improve their security. They may perform penetration testing, vulnerability assessments, and security audits to identify and mitigate potential security threats.

Zardoz is a tool that is designed for automated vulnerability scanning and security assessment of web applications. It helps identify potential security risks and weaknesses in software, enabling developers and security teams to address vulnerabilities before they can be exploited by malicious actors. Zardoz typically focuses on various security aspects, such as: - **Input validation vulnerabilities**: Identifying potential issues related to user input handling that could lead to attacks like SQL injection, cross-site scripting (XSS), and command injection.

Luís Cruls was a Brazilian astronomer and engineer, known for his work in the late 19th and early 20th centuries. He played a significant role in the establishment of the National Observatory of Brazil and contributed to various scientific advancements in the field of astronomy. Cruls is perhaps best known for his involvement in the planning and execution of astronomical expeditions, including one to observe a solar eclipse.

Petr Vaníček is a name that may refer to different individuals, but one of the most notable is a Czech geophysicist known for his work in geodesy and geophysics. He has contributed to various studies and research projects related to the Earth's gravitational field, as well as the study of geodetic and geophysical methods. However, without more specific context, it’s difficult to provide detailed information about him or if there are other individuals with the same name.

The Federal Agency for Cartography and Geodesy (Bundesamt für Kartographie und Geodäsie, BKG) is a German federal agency responsible for providing and overseeing geospatial data and services. It operates under the Federal Ministry of the Interior and Community and plays a key role in the fields of cartography, geodesy, and geographic information systems (GIS).

Dwell time in the context of Global Navigation Satellite Systems (GNSS) refers to the duration that a GNSS receiver spends receiving signals from a specific satellite. This is important for several reasons: 1. **Signal Acquisition**: The longer a receiver dwells on a satellite, the better it can acquire and process the signals. This includes determining the satellite's position and the timing of the signals. 2. **Position Accuracy**: Increased dwell time can lead to improved position accuracy.

Ordnance Datum is a specific reference point used in surveying and mapping that provides a standard level from which height or elevation measurements can be made. In the context of the United Kingdom, the term commonly refers to the mean sea level at Newlyn, Cornwall, which has been used as a base for height measurements since the 19th century. Measurements taken relative to Ordnance Datum are typically expressed in meters or feet above this reference level.

The term "initial points" can refer to different concepts depending on the context in which it is used. Here are a few possible interpretations: 1. **Mathematics and Graphing**: In mathematics, especially when dealing with graphs or functions, "initial points" could refer to the starting points on a graph from which a function is evaluated or analyzed. For example, in a parametric equation, the initial point may be the starting coordinate when \( t = 0 \).

Assisted GNSS (A-GNSS) is a technology that enhances the accuracy and reliability of Global Navigation Satellite System (GNSS) positioning by incorporating additional data, often provided by network services, to support satellite navigation. This is particularly useful in environments where satellite signals may be weak or obscured, such as urban canyons, dense forests, or indoors.

Mel's Hole is an urban legend and a supposed "mystery hole" located in Washington State, which gained notoriety through a series of radio broadcasts in the late 1990s. The story originated from a man named Mel Waters, who claimed to have discovered a deep, seemingly bottomless hole on his property. According to Waters, the hole had bizarre properties, such as the ability to seemingly regenerate objects thrown into it, and it was associated with various supernatural and inexplicable phenomena.

The 114th meridian east is a line of longitude that is located 114 degrees east of the Prime Meridian, which is designated as 0 degrees longitude. This meridian runs from the North Pole to the South Pole and passes through several countries and regions, including parts of eastern Asia, such as Mongolia and China, as well as regions in the Pacific Ocean.

The 43rd meridian east is a line of longitude that is 43 degrees east of the Prime Meridian. It runs from the North Pole to the South Pole and passes through several countries and regions. In the northern hemisphere, the 43rd meridian east passes through parts of Eastern Europe and Russia. Specifically, it traverses countries such as Ukraine, Belarus, and some regions of Russia.

The 139th meridian west is a line of longitude that is 139 degrees west of the Prime Meridian, which passes through Greenwich, England. This meridian runs from the North Pole to the South Pole and crosses various land and water areas. In the northern hemisphere, the 139th meridian west passes through parts of Canada, including some areas of British Columbia and the Yukon Territory. In the southern hemisphere, it crosses through the Pacific Ocean and then reaches parts of Antarctica.

The 85th meridian east is a line of longitude that is located 85 degrees east of the Prime Meridian, which is defined as 0 degrees longitude. It runs from the North Pole to the South Pole and is used in geographical coordinate systems to specify locations on the Earth's surface. In terms of geography, the 85th meridian east passes through several countries, including parts of Russia, Mongolia, India, and Bangladesh.

Basically it looks like the dude got enough money after selling some companies, and now he's doing cooler stuff without much need of money. Not bad.

This section groups conjectures that are famous, solved or unsolved.

They are usually conjectures that have a strong intuitive reasoning, but took a very long time to prove, despite great efforts.
