In January 2020, the FTI Consulting company claimed that in May 2018 with "medium to high confidence" the phone of Jeff Bezos had been hacked by a file sent from the WhatsApp account of the crown prince of Saudi Arabia, Mohammed bin Salman. The Saudi Arabian embassy to the United States has denied the allegations. Billionaire Jeff Bezos, the owner of The Washington Post newspaper and founder of the company Amazon, engaged FTI Consulting in February 2019 after the National Enquirer in January 2019 reported details of Bezos's affair. FTI Consulting did not link the National Enquirer to the hack. In December 2021, the FBI stated they could not find proof to substantiate claims that Saudi Arabia hacked Jeff Bezos phone, and has considered an investigation into those allegations a low priority.

🔗 Video games

MIDI Maze is a networked first-person shooter for the Atari ST developed by Xanth Software F/X and released in 1987 by Hybrid Arts. The game takes place in a maze of untextured walls. The world animates smoothly as the player turns, much like the earlier Wayout, instead of only permitting 90 degree changes of direction. It has been suggested that MIDI Maze, using the built-in MIDI ports of the Atari ST for networking, introduced the concept of deathmatch combat. The game found a wider audience on the Game Boy as Faceball 2000.

The original MIDI Maze team consisted of James Yee as the business manager, Michael Park as the graphic and networking programmer, and George Miller writing the AI and drone logic.

🔗 Computing

Seam carving (or liquid rescaling) is an algorithm for content-aware image resizing, developed by Shai Avidan, of Mitsubishi Electric Research Laboratories (MERL), and Ariel Shamir, of the Interdisciplinary Center and MERL. It functions by establishing a number of seams (paths of least importance) in an image and automatically removes seams to reduce image size or inserts seams to extend it. Seam carving also allows manually defining areas in which pixels may not be modified, and features the ability to remove whole objects from photographs.

The purpose of the algorithm is image retargeting, which is the problem of displaying images without distortion on media of various sizes (cell phones, projection screens) using document standards, like HTML, that already support dynamic changes in page layout and text but not images.

Image Retargeting was invented by Vidya Setlur, Saeko Takage, Ramesh Raskar, Michael Gleicher and Bruce Gooch in 2005. The work by Setlur et al. won the 10-year impact award in 2015.

🔗 Computing

A Gödel machine is a hypothetical self-improving computer program that solves problems in an optimal way. It uses a recursive self-improvement protocol in which it rewrites its own code when it can prove the new code provides a better strategy. The machine was invented by Jürgen Schmidhuber (first proposed in 2003), but is named after Kurt Gödel who inspired the mathematical theories.

The Gödel machine is often discussed when dealing with issues of meta-learning, also known as "learning to learn." Applications include automating human design decisions and transfer of knowledge between multiple related tasks, and may lead to design of more robust and general learning architectures. Though theoretically possible, no full implementation has been created.

The Gödel machine is often compared with Marcus Hutter's AIXItl, another formal specification for an artificial general intelligence. Schmidhuber points out that the Gödel machine could start out by implementing AIXItl as its initial sub-program, and self-modify after it finds proof that another algorithm for its search code will be better.

The gates of hell are various places on the surface of the world that have acquired a legendary reputation for being entrances to the underworld. Often they are found in regions of unusual geological activity, particularly volcanic areas, or sometimes at lakes, caves, or mountains.

🔗 Discworld

The technology depicted in Terry Pratchett's Discworld novels takes two forms: magical and mechanical. Nearly all technology early in the series is at least partially magical, but in more recent books, a form of industrial revolution takes place, with numerous purely mechanical inventions being introduced. In Thud! ancient 'devices' of undisclosed origin and great power were introduced; it is not clear whether these are magical, mechanical, both or neither. Time-travel technology, the exact nature of which is usually unclear, is used by the History Monks. Most Discworld technologies have real-world equivalents, in function if not form.

🔗 History 🔗 Economics 🔗 Politics 🔗 Trade 🔗 Politics/Libertarianism

Mercantilism is a nationalist economic policy that is designed to maximize the exports and minimize the imports of an economy. In other words, it seeks to maximize the accumulation of resources within the country and use those resources for one-sided trade.

The concept aims to reduce a possible current account deficit or reach a current account surplus, and it includes measures aimed at accumulating monetary reserves by a positive balance of trade, especially of finished goods. Historically, such policies may have contributed to war and motivated colonial expansion. Mercantilist theory varies in sophistication from one writer to another and has evolved over time.

Mercantilism promotes government regulation of a nation's economy for the purpose of augmenting and bolstering state power at the expense of rival national powers. High tariffs, especially on manufactured goods, were almost universally a feature of mercantilist policy. Before it fell into decline, mercantilism was dominant in modernized parts of Europe and some areas in Africa from the 16th to the 19th centuries, a period of proto-industrialization. Some commentators argue that it is still practised in the economies of industrializing countries in the form of economic interventionism.

With the efforts of supranational organizations such as the World Trade Organization to reduce tariffs globally, non-tariff barriers to trade have assumed a greater importance in neomercantilism.

The Amarna letters (; sometimes referred to as the Amarna correspondence or Amarna tablets, and cited with the abbreviation EA, for "El Amarna") are an archive, written on clay tablets, primarily consisting of diplomatic correspondence between the Egyptian administration and its representatives in Canaan and Amurru, or neighboring kingdom leaders, during the New Kingdom, spanning a period of no more than thirty years between c. 1360–1332 BC (see here for dates). The letters were found in Upper Egypt at el-Amarna, the modern name for the ancient Egyptian capital of Akhetaten, founded by pharaoh Akhenaten (1350s–1330s BC) during the Eighteenth Dynasty of Egypt. The Amarna letters are unusual in Egyptological research, because they are written not in the language of ancient Egypt, but in cuneiform, the writing system of ancient Mesopotamia. Most are in a variety of Akkadian sometimes characterised as a mixed language, Canaanite-Akkadian; one especially long letter—abbreviated EA 24—was written in a late dialect of Hurrian, and is the longest contiguous text known to survive in that language.

The known tablets total 382, of which 358 have been published by the Norwegian Assyriologist Jørgen Alexander Knudtzon in his work, Die El-Amarna-Tafeln, which came out in two volumes (1907 and 1915) and remains the standard edition to this day. The texts of the remaining 24 complete or fragmentary tablets excavated since Knudtzon have also been made available.

The Amarna letters are of great significance for biblical studies as well as Semitic linguistics because they shed light on the culture and language of the Canaanite peoples in this time period. Though most are written in Akkadian, the Akkadian of the letters is heavily colored by the mother tongue of their writers, who probably spoke an early form of Proto-Canaanite, the language(s) which would later evolve into the daughter languages of Hebrew and Phoenician. These "Canaanisms" provide valuable insights into the proto-stage of those languages several centuries prior to their first actual manifestation.

🔗 Nepal

Nepal Standard Time (NPT) is the time zone for Nepal. With a time offset from Coordinated Universal Time (UTC) of UTC+05:45 all over Nepal, it is one of only three time zones with a 45-minute offset from UTC. (The others are Chatham Island Standard Time, with an offset of UTC+12:45, and the unofficial Australian Central Western Time, with an offset of UTC+08:45.)

NPT is an approximation of Kathmandu mean time, which is 5:41:16 ahead of UTC. The standard meridian passes through the peak of Gaurishankar mountain about 100 kilometres (62 mi) east of Kathmandu.

Nepal used local solar time until 1920, in Kathmandu UTC+05:41:16. In 1920, Nepal adopted Indian Standard Time, UTC+05:30. In 1986 Nepal advanced their clocks by 15 minutes, giving them a time zone of UTC+05:45.

🔗 Technology 🔗 Trains

An atmospheric railway uses differential air pressure to provide power for propulsion of a railway vehicle. A static power source can transmit motive power to the vehicle in this way, avoiding the necessity of carrying mobile power generating equipment. The air pressure, or partial vacuum (i.e., negative relative pressure) can be conveyed to the vehicle in a continuous pipe, where the vehicle carries a piston running in the tube. Some form of re-sealable slot is required to enable the piston to be attached to the vehicle. Alternatively the entire vehicle may act as the piston in a large tube.

Several variants of the principle were proposed in the early 19th century, and a number of practical forms were implemented, but all were overcome by unforeseen disadvantages and discontinued within a few years.

A modern proprietary system has been developed and is in use for short-distance applications. Porto Alegre Metro airport connection is one of them.
