🔗 Astronautilia

🔗 United States 🔗 Books 🔗 Science Fiction

The Astronautilia (Czech: Hvězdoplavba; full title in Greek: Ποιητοῦ ἀδήλου ΑΣΤΡΟΝΑΥΤΙΛΙΑ ἢ ἡ Μικροοδύσσεια ἡ κοσμική; i.e. "An unknown poet's Starvoyage, or the Cosmic Micro-Odyssey") is the magnum opus, written in 1994 under the hellenised pseudonym Ἰωάννης Πυρεῖα, of Czech poet and writer Jan Křesadlo, one of the most unusual works of twentieth-century Czech literature. It was published shortly after his death, as a commemorative first edition.

While no full English translation exists as yet, there is a sample chapter translation online, and a German translation of the fully transcribed and annotated Greek text is in preparation.

🔗 Pizza box form factor

🔗 Computing

In computing, a pizza box is a style of case design for desktop computers or network switches. Pizza box cases tend to be wide and flat, normally 1.5 to 4 inches or 4 to 10 centimetres in height, resembling pizza delivery boxes and thus the name. This is in contrast to a tower system, whose case height is much greater than the width and has an "upright" appearance. In modern usage, the term "pizza box" is normally reserved for very flat cases with height no more than 2 inches (51 mm), while those taller than 2 inches are referred to as desktop cases instead.

The common setup of a pizza box system is to have the display monitor placed directly on top of the case, which serves as a podium to elevate the monitor more towards the user's eye level, and to have other peripherals placed in front and alongside the case. Occasionally, the pizza box may be laid on its sides in a tower-like orientation.

Data General's Aviion Unix server was the first to coin the expression when it advertised in 1991 with the tagline "Who just fit mainframe power in a pizza box?", but most computers generally referred to as pizza box systems were high-end desktop systems such as Sun Microsystems workstations sold in the 1990s, most notably the SPARCstation 1 and SPARCstation 5. Other notable examples have been among the highest-performing desktop computers of their generations, including the SGI Indy, the NeXTstation, and the Amiga 1000, but the form factor was also seen in budget and lower-end lines such as the Macintosh LC family.

The original SPARCstation 1 design included an expansion bus technology, SBus, expressly designed for the form factor; expansion cards were small, especially in comparison to other expansion cards in use at the time such as VMEbus, and were mounted horizontally instead of vertically. PC-compatible computers in this type of case typically use the PCI expansion bus and are usually either a) limited to one or two horizontally placed expansion cards or b) require special low-profile expansion cards, shorter than the PCI cards regular PCs use.

The density of computing power and stackability of pizza box systems also made them attractive for use in data centers. Systems originally designed for desktop use were placed on shelves inside of 19-inch racks, sometimes requiring that part of their cases be cut off for them to fit. Since the late 1990s, pizza boxes have been a common form factor in office cubicles, data centers or industrial applications, where desktop space, rack room and density are critical. Servers in this form factor, as well as higher-end Ethernet switches, are now designed for rack mounting. Rack mount 1U computers come in all types of configurations and depths.

The pizza box form factor for smaller personal systems and thin clients remains in use well into the 21st century, though it is increasingly being superseded by laptops, nettops or All-in-One PC designs that embed the already size-reduced computer onto the keyboard or display monitor.

🔗 GitHub was blocked in Turkey

🔗 Internet 🔗 Computing 🔗 Freedom of speech 🔗 Computing/Websites

GitHub has been the target of censorship from governments using methods ranging from local Internet service provider blocks, intermediary blocking using methods such as DNS hijacking and man-in-the-middle attacks, and denial-of-service attacks on GitHub's servers from countries including China, India, Russia, and Turkey. In all of these cases, GitHub has been eventually unblocked after backlash from users and technology businesses or compliance from GitHub.

🔗 Harvard Mark I

🔗 Computing 🔗 Computing/Early computers

The IBM Automatic Sequence Controlled Calculator (ASCC), called Mark I by Harvard University’s staff, was a general purpose electromechanical computer that was used in the war effort during the last part of World War II.

One of the first programs to run on the Mark I was initiated on 29 March 1944 by John von Neumann. At that time, von Neumann was working on the Manhattan Project, and needed to determine whether implosion was a viable choice to detonate the atomic bomb that would be used a year later. The Mark I also computed and printed mathematical tables, which had been the initial goal of British inventor Charles Babbage for his "analytical engine".

The Mark I was disassembled in 1959, but portions of it are displayed in the Science Center as part of the Harvard Collection of Historical Scientific Instruments. Other sections of the original machine were transferred to IBM and the Smithsonian Institution.

🔗 Cherokee Syllabary

🔗 Languages 🔗 Writing systems 🔗 Indigenous peoples of North America

The Cherokee syllabary is a syllabary invented by Sequoyah in the late 1810s and early 1820s to write the Cherokee language. His creation of the syllabary is particularly noteworthy as he could not previously read any script. He first experimented with logograms, but his system later developed into a syllabary. In his system, each symbol represents a syllable rather than a single phoneme; the 85 (originally 86) characters provide a suitable method to write Cherokee. Although some symbols resemble Latin, Greek, and Cyrillic letters, they are not used to represent the same sounds.

🔗 Wikimedia Foundation v. NSA

🔗 Mass surveillance 🔗 Law

Wikimedia Foundation, et al. v. National Security Agency, et al. is a lawsuit filed by the American Civil Liberties Union (ACLU) on behalf of the Wikimedia Foundation and several other organizations against the National Security Agency (NSA), the United States Department of Justice (DOJ), and other named individuals, alleging mass surveillance of Wikipedia users carried out by the NSA. The suit claims the surveillance system, which NSA calls "Upstream", breaches the First Amendment to the United States Constitution, which protects freedom of speech, and the Fourth Amendment to the United States Constitution, which prohibits unreasonable searches and seizures.

The suit was filed in the United States District Court for the District of Maryland as the NSA is based in Fort Meade, Maryland. The suit was dismissed in October 2015 by Judge T. S. Ellis III; this decision was appealed four months later to the Fourth Circuit Court of Appeals by the Wikimedia Foundation. The Court of Appeals found that the dismissal was valid for all of the plaintiffs except the Foundation, whose allegations the court found "plausible" enough to have legal standing for the case to be remanded to the lower court.

The original plaintiffs besides the Wikimedia Foundation were the National Association of Criminal Defense Lawyers, Human Rights Watch, Amnesty International USA, the PEN American Center, the Global Fund for Women, The Nation magazine, the Rutherford Institute, and the Washington Office on Latin America.

🔗 Polywater

🔗 Physics 🔗 Skepticism

Polywater was a hypothesized polymerized form of water that was the subject of much scientific controversy during the late 1960s. By 1969 the popular press had taken notice and sparked fears of a "polywater gap" in the US.

Increased press attention also brought with it increased scientific attention, and as early as 1970 doubts about its authenticity were being circulated. By 1973 it was found to be illusory, being just water with any number of common organic compounds contaminating it.

Today, polywater is best known as an example of pathological science.

🔗 Google was founded 25 years ago Today

🔗 California 🔗 Companies 🔗 Technology 🔗 California/San Francisco Bay Area 🔗 Internet 🔗 History 🔗 Computing 🔗 Internet culture 🔗 Websites 🔗 Websites/Computing 🔗 Stanford University 🔗 Google

Google was officially launched in 1998 by Larry Page and Sergey Brin to market Google Search, which has become the most used web-based search engine. Larry Page and Sergey Brin, students at Stanford University in California, developed a search algorithm at first known as "BackRub" in 1996, with the help of Scott Hassan and Alan Steremberg. The search engine soon proved successful and the expanding company moved several times, finally settling at Mountain View in 2003. This marked a phase of rapid growth, with the company making its initial public offering in 2004 and quickly becoming one of the world's largest media companies. The company launched Google News in 2002, Gmail in 2004, Google Maps in 2005, Google Chrome in 2008, and the social network known as Google+ in 2011 (which was shut down in April 2019), in addition to many other products. In 2015, Google became the main subsidiary of the holding company Alphabet Inc.

The search engine went through many updates in attempts to eradicate search engine optimization.

Google has engaged in partnerships with NASA, AOL, Sun Microsystems, News Corporation, Sky UK, and others. The company set up a charitable offshoot, Google.org, in 2005.

The name Google is a misspelling of Googol, the number 1 followed by 100 zeros, which was picked to signify that the search engine was intended to provide large quantities of information.

🔗 Quadratic Voting

🔗 Politics

Quadratic voting is a collective decision-making procedure where individuals allocate votes to express the degree of their preferences, rather than just the direction of their preferences. By doing so, quadratic voting helps enable users to address issues of voting paradox and majority-rule. Quadratic voting works by allowing users to 'pay' for additional votes on a given matter to express their preference for given issues more strongly, resulting in voting outcomes that are aligned with the highest willingness to pay outcome, rather than just the outcome preferred by the majority regardless of the intensity of individual preferences. The payment for votes may be through either artificial or real currencies (e.g. with tokens distributed equally among voting members or with real money). Under various sets of conditions, quadratic voting has been shown to be much more efficient than one-person-one-vote in aligning collective decisions with doing the most good for the most people. Quadratic voting (abbreviated as QV) is considered a promising alternative to existing democratic structures to solve some of the known failure modes of one-person-one-vote democracies. Quadratic voting is a variant of cumulative voting in the class of cardinal voting. It differs from Cumulative voting by altering "the cost" and "the vote" relation from linear to quadratic.

Quadratic voting is based upon market principles, where each voter is given a budget of vote credits that they have the personal decisions and delegation to spend in order to influence the outcome of a range of decisions. If a participant has a strong preference for or against a specific decision, additional votes could be allocated to proportionally demonstrate the voter's preferences. A vote pricing rule determines the cost of additional votes, with each vote becoming increasingly more expensive. By increasing voter credit costs, this demonstrates an individual's preferences and interests toward the particular decision. This money is eventually cycled back to the voters based upon per capita. Both Weyl and Lalley conducted research to demonstrate that this decision-making policy expedites efficiency as the number of voters increases. The simplified formula on how quadratic voting functions is:

cost to the voter = (number of votes)2.

The quadratic nature of the voting suggests that a voter can use their votes more efficiently by spreading them across many issues. For example, a voter with a budget of 16 vote credits can apply 1 vote credit to each of the 16 issues. However, if the individual has a stronger passion or sentiment on an issue, they could allocate 4 votes, at the cost of 16 credits, to the singular issue, effectively using up their entire budget. This mechanism towards voting demonstrates that there is a large incentive to buy and sell votes, or to trade votes. Using this anonymous ballot system provides identity protection from vote buying or trading since these exchanges cannot be verified by the buyer or trader.
