In computer security, a cold boot attack (or to a lesser extent, a platform reset attack) is a type of side channel attack in which an attacker with physical access to a computer performs a memory dump of a computer's random access memory by performing a hard reset of the target machine. Typically, cold boot attacks are used to retrieve encryption keys from a running operating system for malicious or criminal investigative reasons. The attack relies on the data remanence property of DRAM and SRAM to retrieve memory contents that remain readable in the seconds to minutes after power has been removed.

An attacker with physical access to a running computer typically executes a cold boot attack by cold-booting the machine and booting a lightweight operating system from a removable disk to dump the contents of pre-boot physical memory to a file. An attacker is then free to analyze the data dumped from memory to find sensitive data, such as the keys, using various forms of key finding attacks. Since cold boot attacks target random access memory, full disk encryption schemes, even with a trusted platform module installed are ineffective against this kind of attack. This is because the problem is fundamentally a hardware (insecure memory) and not a software issue. However, malicious access can be prevented by limiting physical access and using modern techniques to avoid storing sensitive data in random access memory.

A propfan, also called an open rotor engine, or unducted fan, is a type of aircraft engine related in concept to both the turboprop and turbofan, but distinct from both. The design is intended to offer the speed and performance of a turbofan, with the fuel economy of a turboprop. A propfan is typically designed with a large number of short, highly twisted blades, similar to a turbofan's bypass compressor (the fan itself). For this reason, the propfan has been variously described as an "unducted fan" or an "ultra-high-bypass (UHB) turbofan."

The Lun-class ekranoplan is a ground effect vehicle (GEV) designed by Rostislav Evgenievich Alexeyev in 1975 and used by the Soviet and Russian navies from 1987 until sometime in the late 1990s.

It flew using the lift generated by the ground effect of its large wings when within about four metres (13 ft) above the surface of the water. Although they might look similar to regular aircraft, and have related technical characteristics, ekranoplans like the Lun are not aircraft, seaplanes, hovercraft, nor hydrofoils. Rather, "ground effect" is a distinct technology. The International Maritime Organization classifies these vehicles as maritime ships.

The name Lun comes from the Russian word for harrier.

An auto-antonym or autantonym, also called a contronym, contranym or Janus word, is a word with multiple meanings (senses) of which one is the reverse of another. For example, the word cleave can mean "to cut apart" or "to bind together". This phenomenon is called enantiosemy, enantionymy (enantio- means "opposite"), antilogy or autantonymy. An enantiosemic term is necessarily polysemic.

🔗 Biography 🔗 Germany

Gustl Ferdinand Mollath (born 7 November 1956 in Nuremberg) is a German man who was acquitted during a criminal trial in 2006 on the basis of diminished criminal responsibility. He was committed to a high-security psychiatric hospital, as the court deemed him a danger to the public and declared him insane based on expert diagnoses of paranoid personality disorder. The judgment became the basis of controversy when elements of his supposed delusions regarding money-laundering activities at a major bank were found to be true. Mollath had consistently claimed there was a conspiracy to have him locked up in a psychiatric care ward because of his incriminating knowledge; evidence discovered in 2012 made his claims appear plausible.

In 2006, after being accused of assaulting his former wife, Petra Mollath, Gustl Mollath was tried at the District Court of Nürnberg-Fürth for aggravated assault and wrongful deprivation of personal liberty of his ex-wife as well as damage to property. The court considered the charges proven but acquitted Mollath on the basis of finding him criminally insane. A pivotal argument for Mollath's insanity, besides the general impression he made, was that he insisted his wife was involved in a complex system of tax evasion. The court came to call it a paranoid belief system Mollath had developed, which led him to accuse many people of being part of a conspiracy and acting irrationally and aggressively, by puncturing car tires of people in a way that could lead to accidents.

In 2012, the case was widely publicized when evidence brought to the attention of state prosecutors showed that suspicious activities were carried out over several years by members of staff (including Mollath's ex-wife) at the Munich-based HypoVereinsbank, as detailed in an internal audit report carried out by the bank in 2003. The reported money transfers were not illegal per se.

In June 2013, Mollath's former wife spoke for the first time to the press. According to her, Gustl Mollath was continually violent towards her, prior and during marriage. The alleged money laundering activities became an issue only after their divorce, which directly contradicts Gustl Mollath's version that he had suffered from the illegal activities of his former wife. Gustl Mollath has denied the allegations levied against him and has said that he was being persecuted for blowing the whistle on tax evasion at HypoVereinsbank.

On August 6, 2013, the Higher Regional Court of Nuremberg ordered a retrial and Mollath's immediate release, overturning a verdict of the Regional Court of Regensburg that had blocked a retrial.

Mollath's 2018 action for damages by the unlawful custody has been concluded in November 2019 by an ex gratia payment of €600,000 by the defendant Free State of Bavaria.

🔗 Psychology

The Truman Show delusion, informally known as Truman syndrome, is a type of delusion in which the person believes that their lives are staged reality shows, or that they are being watched on cameras. The term was coined in 2008 by brothers Joel Gold and Ian Gold, a psychiatrist and a neurophilosopher, respectively, after the film The Truman Show.

The Truman Show delusion is not officially recognized nor listed in the Diagnostic and Statistical Manual of the American Psychiatric Association.

Air raid shelters, also known as bomb shelters, are structures for the protection of non-combatants as well as combatants against enemy attacks from the air. They are similar to bunkers in many regards, although they are not designed to defend against ground attack (but many have been used as defensive structures in such situations).

Prior to World War II, in May 1924, an Air Raid Precautions Committee was set up in the United Kingdom. For years, little progress was made with shelters because of the apparently irreconcilable conflict between the need to send the public underground for shelter and the need to keep them above ground for protection against gas attacks. In February 1936 the Home Secretary appointed a technical Committee on Structural Precautions against Air Attack.

By November 1937, there had only been slow progress, because of a serious lack of data on which to base any design recommendations and the Committee proposed that the Home Office should have its own department for research into structural precautions, rather than relying on research work done by the Bombing Test Committee to support the development of bomb design and strategy. This proposal was eventually implemented in January 1939.

During the Munich crisis, local authorities dug trenches to provide shelter. After the crisis, the British Government decided to make these a permanent feature, with a standard design of precast concrete trench lining. Unfortunately these turned out to perform very poorly. They also decided to issue free to poorer households the Anderson shelter, and to provide steel props to create shelters in suitable basements.

The theory of constraints (TOC) is a management paradigm that views any manageable system as being limited in achieving more of its goals by a very small number of constraints. There is always at least one constraint, and TOC uses a focusing process to identify the constraint and restructure the rest of the organization around it. TOC adopts the common idiom "a chain is no stronger than its weakest link". That means that organizations and processes are vulnerable because the weakest person or part can always damage or break them, or at least adversely affect the outcome.
