π 100 Years β The Movie You Will Never See
100 Years is an upcoming science fiction film written by John Malkovich and directed by Robert Rodriguez. Advertised in 2015 with the tagline "The Movie You Will Never See", it is due to be released on November 18, 2115. The 100 year span matches the time it takes for a bottle of Louis XIII Cognac to be properly aged before its release to consumers. The film stars an international ensemble, with American actor John Malkovich, Taiwanese actress Shuya Chang, and Chilean actor Marko Zaror.
100 Years will apparently be a short film, Rodriguez having stated in a 2019 interview with French YouTuber InThePanda: "I was making several short films for them, and I finished that one first, we shot that one first, I thought that was gonna be a commercial or something. And then I showed them the movie and they said 'Yeah, that's great, that's great. That's the one we lock away.' And I said 'What? That's the one you lock away? What about the other one with the future--' 'No, that's the commercial.' [...] The one that I was most attached to was the one they locked away."

π MasterβSlave Morality
Masterβslave morality (German: Herren- und Sklavenmoral) is a central theme of Friedrich Nietzsche's works, particularly in the first essay of his book, On the Genealogy of Morality. Nietzsche argued that there were two fundamental types of morality: "master morality" and "slave morality". Master morality values pride and power, while slave morality values kindness, empathy, and sympathy. Master morality judges actions as good or bad (e.g. the classical virtues of the noble man versus the vices of the rabble), unlike slave morality, which judges by a scale of good or evil intentions (e. g. Christian virtues and vices, Kantian deontology).
For Nietzsche, a morality is inseparable from the culture which values it, meaning that each culture's language, codes, practices, narratives, and institutions are informed by the struggle between these two moral structures.

π Wheatstone System
The Wheatstone system was an automated telegraph system that replaced a human operator with machines capable of sending and recording Morse code at a consistent fast rate. The system included a perforator, which prepared punched paper tape called a Wheatstone slip, a transmitter that read the tape and converted the symbols into dots and dashes encoded as mark and space electric currents on the telegraph line, and a receiver at the other end of the telegraph line that printed the Morse symbols. The system was invented by Charles Wheatstone. Enhancements could be made so that it was a duplex system, able to send and receive on the same line simultaneously.
The Wheatstone slip was a paper tape that contained holes in a pattern to control the mark and space signals on the telegraph line. The paper tape was from 0.46 to 0.48 inches in width, (but the standard width is from 0.472 to 0.475 inches) and a standard thickness of 0.004 to 0.0045 inches. Olive oil coating lubricated the punch process. There were three rows of holes. The middle row forms a rack so that a star wheel can move the paper forward. Every used position on the tape has a middle hole punched. The top hole indicates when to turn on the mark signal on the line, and the bottom hole says to turn off the mark signal. Each vertical column represents a time interval in the Morse code, including the spacing between the holes. The holes are spaced 0.1 inches apart. A column of three holes turns on the mark at the beginning of the interval, and turns it off at the end making a dot. If there is a top hole without a bottom, and then the next column has a bottom without a top hole, mark is on for three intervals, and a dash is represented. If there is only a centre hole, then nothing changes, and this would normally be used to put in space between letters and words.
The Wheatstone perforator was a manually operated hole punch machine to produce Wheatstone slips. It had three buttons (or keys) labelled "A", "A1" and "A2". "A" punched the pattern for dot, "A1" punched the pattern for space, and "A2" punched the dash pattern in two columns. The keys were so difficult to press that fist-held rubber-tipped mallets were used to depress them and operate the punches. Using this, invalid combinations of holes could not be produced. The blank paper tape was fed in from the right over a roller and came out the left side. It was oriented in a vertical plane. The paper punches were labelled with numbers: 1 for the top hole of the dot, 2 for the sprocket hole for dot, and 3 for the bottom hole for dot. When a dash was punched, extra hole punches to the right punched a centre hole with number 4 and a bottom hole with number 5. The perforator was introduced in 1867. It enabled transmission speeds on a telegraph line to increase to 70 words per minute. The very first message ever punched onto a tape was "SOS EIOS". The manual perforator was subsequently replaced by keyboard perforators like the Gell keyboard perforator or Kleinschmidt keyboard perforator.
Each of the keys had a spring to restore its position after pressing. Each key moved a corresponding lever underneath the instrument. The other end of the levers protruded up into the back of the mechanism. Each punch rod also had a spring to put it back in place after punching a hole. For space and dot keying (A or A1) the star wheel was only allowed to turn one position by a pawl, and the paper tape only moved forward one position. However, when key A2 was hit, the corresponding lever B2 raised a bar (h) which allowed another lever attached to the pawl to move further back when the star wheel rotated, and the wheel could turn two positions, for a dash. The distance the paper tape moved for each position was determined by how far lever k moved, and its range of movement had to be set by adjusting screws i and t. A flat spring g stored energy from the punch to move the paper. The force of the spring was determined by adjusting screws n and n'. A guide roller (r) with a groove was pressed by an adjustable spring to press the pawl against the star wheel. The star wheel was on a frame with a piece sticking out the left hand side as a lever. When the operator wanted to insert paper tape, this lever was pulled, and the star wheel retracted from the paper.
The Wheatstone transmitter read a paper tape (Wheatstone slip) and converted the dot pattern into mark and space symbols on the telegraph line. It worked by two rods alternately rising up to sample the holes in the tape. First of all the top hole was probed, and if the rod could go through, it moved a compound lever that connected the mark signal to the line. With no hole the lever remained unmoved. Next the top hole rod dropped and the bottom hole rod checked whether there was a bottom hole in the tape. If there was, the compound lever was moved back to connect the space signal on the line. If there was no hole, the compound lever was left alone as it was. An extra switch enabled the transmitter to be bypassed so that a Morse key could be used instead.
The Wheatstone receiver converted the signal on the telegraph line to an inked pattern on a paper strip. An electromagnet electrically connected to the telegraph line moved an inking wheel to press against the paper. A clockwork mechanism advanced the paper tape, and turned the inking wheel, and an ink supply wheel. The paper advance speed could be adjusted between 7 and 60 feet per minute. Power to the clockwork had three sources: it could be a coiled spring, a weight, or an electric motor. Paper spools were stored in drawers beneath the reader to allow quick change when one was exhausted. The ink supply wheel turned in an inkwell. The machine was started and stopped by use of a lever. In electrical characteristics, the electromagnet had two windings, each of 100 ohms resistance. These could be connected in parallel or series to achieve a 50 or 200 ohm resistance, to better match the telegraph line. Other maintenance that might have been required was cleaning of the marker and supply wheels, adjusting the armature-coil spacing to avoid a marking or spacing bias, and cleaning the sounding tongue and contact points.
The Wheatstone telegram consisted of strips of paper tape with the Morse code printed on it, pasted on a form. The telegram would later be retyped to make a final presentable message for the recipient.

π Possible explanations for the slow progress of AI research
Artificial general intelligence (AGI) is the hypothetical intelligence of a machine that has the capacity to understand or learn any intellectual task that a human being can. It is a primary goal of some artificial intelligence research and a common topic in science fiction and futures studies. AGI can also be referred to as strong AI, full AI, or general intelligent action. (Some academic sources reserve the term "strong AI" for machines that can experience consciousness.)
Some authorities emphasize a distinction between strong AI and applied AI (also called narrow AI or weak AI): the use of software to study or accomplish specific problem solving or reasoning tasks. Weak AI, in contrast to strong AI, does not attempt to perform the full range of human cognitive abilities.
As of 2017, over forty organizations were doing research on AGI.

π Daimler Reitwagen
The Daimler Petroleum Reitwagen ("riding car") or Einspur ("single track") was a motor vehicle made by Gottlieb Daimler and Wilhelm Maybach in 1885. It is widely recognized as the first motorcycle. Daimler is often called "the father of the motorcycle" for this invention. Even when the three steam powered two wheelers that preceded the Reitwagen, the Michaux-Perreaux and Roper of 1867β1869, and the 1884 Copeland, are considered motorcycles, it remains nonetheless the first petrol internal combustion motorcycle, and the forerunner of all vehicles, land, sea and air, that use its overwhelmingly popular engine type.

π Battle Chess
Battle Chess is a computer game version of chess in which the chess pieces come to life and battle one another when capturing. It was originally developed and released by Interplay Entertainment for the Amiga in 1988 and subsequently on many other systems, including 3DO Interactive Multiplayer, Acorn Archimedes, Amiga CD32, Amiga CDTV, Apple IIGS, Apple IIe, Atari ST, Commodore 64, MS-DOS, FM Towns, NES, Mac OS, NEC PC-9801, X68000 and Microsoft Windows. In 1991, Battle Chess Enhanced was released by Interplay for the PC, featuring improved VGA graphics and a symphonic musical score that played from the CD-ROM.
Battle Chess was critically acclaimed and commercially successful, resulting in two official follow-ups as well as several inspired games. Its remake, Battle Chess: Game of Kings, was released on Steam on December 11, 2015.

π Dril
@dril is a pseudonymous Twitter user best known for his idiosyncratic style of absurdist humor and non sequiturs. The account, its author, and the character associated with the tweets are all commonly referred to as dril (the handle without the at sign) or wint (the account's display name), both rendered lowercase but often capitalized by others. Since his first tweet in 2008, dril has become a popular and influential Twitter user with more than one million followers.
dril is one of the most notable accounts associated with "Weird Twitter", a subculture on the site that shares a surreal, ironic sense of humor. The character associated with dril is highly distinctive, often described as a bizarre reflection of a typical male American Internet user. Other social media users have repurposed dril's tweets for humorous or satiric effect in a variety of political and cultural contexts. Many of dril's tweets, phrases, and tropes have become familiar parts of Internet slang.
The author behind dril remained unknown for years, with the few available details about the author's life fueling speculation about his identity. In 2017, dril's author was "doxxed" (in other words, his identity was exposed) in a post that went viral and received media attention. After the doxxing, many Twitter users and journalists preferred to preserve dril's pseudonymity out of respect for the author's personal privacy and the character's mystique.
Beyond tweeting, dril has created animated short films and contributed illustrations and writing to other artists' collaborative projects. His first book, Dril Official "Mr. Ten Years" Anniversary Collection (2018), is a compilation of the account's "greatest hits" alongside new illustrations. In 2019 he announced the launch of a streaming web series called Truthpoint: Darkweb Rising, an InfoWars parody co-created with comedian Derek Estevez-Olsen for Adult Swim. Writers have praised dril for the originality and humor of his tweets; for example, the poet Patricia Lockwood called dril "a master of tone [and] character," and The A.V. Club dubbed him "arguably the most iconic Twitter account in the history of social media."

π Kobayashi Maru
The Kobayashi Maru is a training exercise in the fictional Star Trek universe designed to test the character of Starfleet Academy cadets in a no-win scenario. The Kobayashi Maru test was first depicted in the opening scene of the film Star Trek II: The Wrath of Khan and also appears in the 2009 film Star Trek. Screenwriter Jack B. Sowards is credited with inventing the test. The test's name is occasionally used among Star Trek fans or those familiar with the series to describe a no-win scenario, a test of one's character or a solution that involves redefining the problem and managing an insurmountable scenario gracefully.
The notional primary goal of the exercise is to rescue the civilian vessel Kobayashi Maru in a simulated battle with the Klingons. The disabled ship is located in the Klingon Neutral Zone, and any Starfleet ship entering the zone would cause an interstellar border incident. The approaching cadet crew must decide whether to attempt rescue of the Kobayashi Maru crewβendangering their own ship and livesβor leave the Kobayashi Maru to certain destruction. If the cadet chooses to attempt rescue, the simulation is designed to guarantee that the cadet's ship enters a situation that he or she will have absolutely no chance of winning, escaping, negotiating or even surviving.

π X17 Particle
The X17 particle is a hypothetical subatomic particle proposed by Attila Krasznahorkay and his colleagues to explain certain anomalous measurement results. The particle has been proposed to explain wide angles observed in the trajectory paths of particles produced during a nuclear transition of beryllium-8 atoms and in stable helium atoms. The X17 particle could be the force carrier for a postulated fifth force, possibly connected with dark matter, and has been described as a protophobic (i.e., ignoring protons) X boson with a mass near 17Β MeV.

π Smith Chart
The Smith chart, invented by Phillip H. Smith (1905β1987), and T. Mizuhashi, is a graphical calculator or nomogram designed for electrical and electronics engineers specializing in radio frequency (RF) engineering to assist in solving problems with transmission lines and matching circuits. The Smith chart can be used to simultaneously display multiple parameters including impedances, admittances, reflection coefficients, scattering parameters, noise figure circles, constant gain contours and regions for unconditional stability, including mechanical vibrations analysis. The Smith chart is most frequently used at or within the unity radius region. However, the remainder is still mathematically relevant, being used, for example, in oscillator design and stability analysis. While the use of paper Smith charts for solving the complex mathematics involved in matching problems has been largely replaced by software based methods, the Smith charts display is still the preferred method of displaying how RF parameters behave at one or more frequencies, an alternative to using tabular information. Thus most RF circuit analysis software includes a Smith chart option for the display of results and all but the simplest impedance measuring instruments can display measured results on a Smith chart display.
