Manjaro Linux
Manjaro Linux, or simply Manjaro /mənˈdʒɑːroʊ/, is an open source operating system for computers. It is a distribution of Linux based on the Arch Linux distribution. Manjaro Linux has a focus on user friendliness and accessibility and the system itself is designed to work fully ‘straight out of the box’ with its variety of pre-installed software. It features a rolling release update model and uses pacman as its package manager.

Nap Pods
Nap pods also known as sleep pods, napping pods or nap capsules are special types of structures or chairs, often used in corporate/ workplace environments, hospitals and universities, that allow people to nap. Users use the pods to take private sleep breaks, often aided by technology and ambient features. Nap pods have emerged in corporate environments, hospitals, universities, airports and other public places. Their supposed efficacy is rooted in research that suggests that 20-minute naps could reduce signs of fatigue, boost energy levels, improve focus, boost productivity, improve mood, enhance learning, reduce stress and reduce the risk of cardiovascular disease.

PDP-10
Digital Equipment Corporation (DEC)'s PDP-10, later marketed as the DECsystem-10, is a mainframe computer family manufactured beginning in 1966 and discontinued in 1983. 1970s models and beyond were marketed under the DECsystem-10 name, especially as the TOPS-10 operating system became widely used. The PDP-10's architecture is almost identical to that of DEC's earlier PDP-6, sharing the same 36-bit word length and slightly extending the instruction set (but with improved hardware implementation). Some aspects of the instruction set are unusual, most notably the byte instructions, which operate on bit fields of any size from 1 to 36 bits inclusive, according to the general definition of a byte as a contiguous sequence of a fixed number of bits. The PDP-10 was found in many university computing facilities and research labs during the 1970s, the most notable being Harvard University's Aiken Computation Laboratory, MIT's AI Lab and Project MAC, Stanford's SAIL, Computer Center Corporation (CCC), ETH (ZIR), and Carnegie Mellon University. Its main operating systems, TOPS-10 and TENEX, were used to build out the early ARPANET. For these reasons, the PDP-10 looms large in early hacker folklore. Projects to extend the PDP-10 line were eclipsed by the success of the unrelated VAX superminicomputer, and the cancellation of the PDP-10 line was announced in 1983. By late 1980 DEC reportedly had sold "about 1500 DECsystem-10s."

SPAdes
SPAdes (St. Petersburg genome assembler) is a genome assembly algorithm which was designed for single cell and multi-cells bacterial data sets. Therefore, it might not be suitable for large genomes projects. SPAdes works with Ion Torrent, PacBio, Oxford Nanopore, and Illumina paired-end, mate-pairs and single reads. SPAdes has been integrated into Galaxy pipelines by Guy Lionel and Philip Mabon.

Focke-Achgelis Fa 223
The Focke-Achgelis Fa 223 Drache (English: Dragon) was a helicopter developed by Germany during World War II. A single 750-kilowatt (1,010 hp) Bramo 323 radial engine powered two three-bladed 11.9-metre (39 ft) rotors mounted on twin booms on either side of the 12.2-metre-long (40 ft) cylindrical fuselage. Although the Fa 223 is noted for being the first helicopter to attain production status, production of the helicopter was hampered by Allied bombing of the factory, and only 20 were built. The Fa 223 could cruise at 175 kilometres per hour (109 mph) with a top speed of 182 km/h (113 mph), and climb to an altitude of 7,100 m (23,300 ft). The Drache could transport cargo loads of over 1,000 kg (2,200 lb) at cruising speeds of 121 km/h (75 mph) and altitudes approaching 2,440 m (8,010 ft).

Outline of Transhumanism
The following outline provides an overview of and a topical guide to transhumanism, an international intellectual and cultural movement that affirms the possibility and desirability of fundamentally transforming the human condition by developing and making widely available technologies to eliminate aging and to greatly enhance human intellectual, physical and psychological capacities. Transhumanist thinkers study the potential benefits and dangers of emerging and hypothetical technologies that could overcome fundamental human limitations as well as study the ethical matters involved in developing and using such technologies. They predict that human beings may eventually be able to transform themselves into beings with such greatly expanded abilities as to merit the label posthuman.

Plant Collecting
Plant collecting is the acquisition of plant specimens for the purposes of research, cultivation, or as a hobby. Plant specimens may be kept alive, but are more commonly dried and pressed to preserve the quality of the specimen. Plant collecting is an ancient practice with records of a Chinese botanist collecting roses over 5000 years ago. Herbaria are collections of preserved plants samples and their associated data for scientific purposes. The largest herbarium in the world exist at the Muséum National d'Histoire Naturelle, in Paris, France. Plant samples in herbaria typically include a reference sheet with information about the plant and details of collection. This detailed and organized system of filing provides horticulturist and other researchers alike with a way to find information about a certain plant, and a way to add new information to an existing plant sample file. The collection of live plant specimens from the wild, sometimes referred to as plant hunting, is an activity that has occurred for centuries. The earliest recorded evidence of plant hunting was in 1495 BC when botanists were sent to Somalia to collect incense trees for Queen Hatshepsut. The Victorian era saw a surge in plant hunting activity as botanical adventurers explored the world to find exotic plants to bring home, often at considerable personal risk. These plants usually ended up in botanical gardens or the private gardens of wealthy collectors. Prolific plant hunters in this period included William Lobb and his brother Thomas Lobb, George Forrest, Joseph Hooker, Charles Maries and Robert Fortune.

Grey Water
Grey water (also spelled gray water in the United States) or sullage refers to wastewater generated in households or office buildings from streams without fecal contamination, i.e., all streams except for the wastewater from toilets. Sources of grey water include sinks, showers, baths, washing machines or dishwashers. As grey water contains fewer pathogens than domestic wastewater, it is generally safer to handle and easier to treat and reuse onsite for toilet flushing, landscape or crop irrigation, and other non-potable uses. The application of grey water reuse in urban water systems provides substantial benefits for both the water supply subsystem, by reducing the demand for fresh clean water, and the wastewater subsystems by reducing the amount of wastewater required to be conveyed and treated. Treated grey water has many uses, for example, toilet flushing or irrigation.

Television Infrared Observation Satellite
TIROS, or Television InfraRed Observation Satellite, is a series of early weather satellites launched by the United States , beginning with TIROS-1 in 1960. TIROS was the first satellite that was capable of remote sensing of the Earth, enabling scientists to view the Earth from a new perspective: space. The program, promoted by Harry Wexler, proved the usefulness of satellite weather observation, at a time when military reconnaissance satellites were secretly in development or use. TIROS demonstrated at that time that "the key to genius is often simplicity". TIROS is an acronym of "Television InfraRed Observation Satellite" and is also the plural of "tiro" which means "a young soldier, a beginner". Participants in the TIROS project included the National Aeronautics and Space Administration (NASA), United States Army Signal Research and Development Laboratory, Radio Corporation of America (RCA), the United States Weather Bureau Service, the United States Naval Photographic Interpretation Center (NPIC), the Environmental Science Services Administration (ESSA), and the National Oceanic and Atmospheric Administration (NOAA).
