π The Art of Being Right
The Art of Being Right: 38 Ways to Win an Argument (also The Art of Controversy, or Eristic Dialectic: The Art of Winning an Argument; German: Eristische Dialektik: Die Kunst, Recht zu behalten; 1831) is an acidulous, sarcastic treatise written by the German philosopher Arthur Schopenhauer. In it, Schopenhauer examines a total of thirty-eight methods of showing up one's opponent in a debate. He introduces his essay with the idea that philosophers have concentrated in ample measure on the rules of logic, but have not (especially since the time of Immanuel Kant) engaged with the darker art of the dialectic, of controversy. Whereas the purpose of logic is classically said to be a method of arriving at the truth, dialectic, says Schopenhauer, "...on the other hand, would treat of the intercourse between two rational beings who, because they are rational, ought to think in common, but who, as soon as they cease to agree like two clocks keeping exactly the same time, create a disputation, or intellectual contest."

π Mars Curiosity Operating System: VxWorks
VxWorks is a real-time operating system (RTOS) developed as proprietary software by Wind River Systems, a wholly owned subsidiary of TPG Capital, US. First released in 1987, VxWorks is designed for use in embedded systems requiring real-time, deterministic performance and, in many cases, safety and security certification, for industries, such as aerospace and defense, medical devices, industrial equipment, robotics, energy, transportation, network infrastructure, automotive, and consumer electronics.
VxWorks supports Intel architecture, POWER architecture, ARM architectures and RISC-V. The RTOS can be used in multicore asymmetric multiprocessing (AMP), symmetric multiprocessing (SMP), and mixed modes and multi-OS (via Type 1 hypervisor) designs on 32- and 64-bit processors.
VxWorks comes with the kernel, middleware, board support packages, Wind River Workbench development suite and complementary third-party software and hardware technologies. In its latest release, VxWorks 7, the RTOS has been re-engineered for modularity and upgradeability so the OS kernel is separate from middleware, applications and other packages. Scalability, security, safety, connectivity, and graphics have been improved to address Internet of Things (IoT) needs.

π Terraforming of Mars
Terraforming of Mars is a procedure that would comprise of planetary engineering project or concurrent projects, with the goal of transforming the planet from one hostile to terrestrial life to one that can sustainably host humans and other lifeforms free of protection or mediation. The process would presumably involve the rehabilitation of the planet's extant climate, atmosphere, and surface through a variety of resource-intensive initiatives, and the installation of a novel ecological system or systems.
Justifications for choosing Mars over other potential terraforming targets include the presence of water and a geological history that suggests it once harbored a dense atmosphere similar to Earthβs. Hazards and difficulties include low gravity, low light levels relative to Earthβs, and the lack of a magnetic field.
Objections to the project include questions about its feasibility, general ethical concerns about terraforming, and the considerable cost that such an undertaking would involve. Reasons for terraforming the planet include allaying concerns about resource use and depletion on Earth and arguments that the altering and subsequent or concurrent settlement of other planets decreases the odds of humanity's extinction.
Disagreement exists about whether current technology could render the planet habitable.

π United States Pirate Party
The United States Pirate Party (USPP) is an American political party founded in 2006 by Brent Allison and Alex English. The party's platform is aligned with the global Pirate movement, and supports reform of copyright laws to reflect open source and free culture values, government transparency, protection of privacy and civil liberties. The United States Pirate Party also advocates for evidence-based policy, egalitarianism, meritocracy and the hacker ethic as well as the rolling back of corporate personhood and corporate welfare. The USPP has also made a priority to advocate for changes in the copyright laws and removal of patents. It is the belief of the party that these restrictions greatly hinder the sharing and expansion of knowledge and resources.
The party's national organization has existed in multiple incarnations since its 2006 founding. Its most recent is the Pirate National Committee (PNC), formed in 2012 as a coalition of state parties. The PNC officially recognizes Pirate parties from 8 states, and tracks and assists in the growth of more state parties throughout the United States. The board of the USPP is the board of the PNC. The current Chair of the Pirate National Committee is Lindsay-Anne Gorski (nΓ©e Brunner).

π List of Unexplained Sounds
The following is a list of unidentified, or formerly unidentified, sounds. All of the sound files in this article have been sped up by at least a factor of 16 to increase intelligibility by condensing them and raising the frequency from infrasound to a more audible and reproducible range.

π "Do Not Track" HTTP header supported by IE, Opera, FF, Safari but not Chrome
Do Not Track (DNT) was a proposed HTTP header field, designed to allow internet users to opt-out of tracking by websitesβwhich includes the collection of data regarding a user's activity across multiple distinct contexts, and the retention, use, or sharing of data derived from that activity outside the context in which it occurred.
The Do Not Track header was originally proposed in 2009 by researchers Christopher Soghoian, Sid Stamm, and Dan Kaminsky. Efforts to standardize Do Not Track by the W3C in the Tracking Preference Expression (DNT) Working Group did not make it past the Candidate Recommendation stage and ended in September 2018 due to insufficient deployment and support.Mozilla Firefox became the first browser to implement the feature, while Internet Explorer, Apple's Safari, Opera and Google Chrome all later added support.
DNT is not widely adopted by the industry, with companies citing the lack of legal mandates for its use, as well as unclear standards and guidelines for how websites are to interpret the header. Thus, it is not guaranteed that enabling DNT will actually have any effect at all. The W3C disbanded its DNT working group in January 2019, citing insufficient support and adoption. Apple discontinued support for DNT the following month.

π Lego - the Largest Tyre Manufacturer in the World
A Lego tire is a rubber tire manufactured by the toy building block company The Lego Group for use on vehicles within their Lego building sets. The tires are available in a range of sizes depending on the application. Lego first began manufacturing tires in 1962 and included them in what would become their most popular set at the time. Previously, the only tire options for Lego users were either purchasing complete car kits from Lego, or building their own tires out of existing Lego blocks. Lego produced 318 million tires in 2011, making them the world's largest tire manufacturer by number of units produced.

π Satellite killed by trajectory patent
AMC-14 is a communications satellite. Initially owned by SES Americom, AMC-14 was designed to be placed in geostationary orbit, following launch on a Proton rocket. Built by Lockheed Martin and based on the A2100 satellite bus, AMC-14 was to have been located at 61.5Β° west longitude for DISH Network service.
It was launched atop a Proton-M/Briz-M rocket at 23:18:55 GMT on 14 March 2008, from LC-200/39 at the Baikonur Cosmodrome in Kazakhstan. The satellite was placed in an unusable orbit, following a malfunction of the Briz-M upper stage. Over a six-month period, it was maneuvered into a geosynchronous orbit, and is now near 35Β° East and in an inclined orbit.

π Darwin (1960s programming game)
Darwin was a programming game invented in August 1961 by Victor A. Vyssotsky, Robert Morris Sr., and M. Douglas McIlroy. (Dennis Ritchie is sometimes incorrectly cited as a co-author, but was not involved.) The game was developed at Bell Labs, and played on an IBM 7090 mainframe there. The game was only played for a few weeks before Morris developed an "ultimate" program that eventually brought the game to an end, as no-one managed to produce anything that could defeat it.
