Files transferred over shell protocol

Files transferred over Shell protocol (FISH) is a network protocol that uses Secure Shell (SSH) or Remote Shell (RSH) to transfer files between computers and manage remote files.

The advantage of FISH is that all it requires on the server-side is an SSH or RSH implementation, Unix shell, and a set of standard Unix utilities (like ls, cat or dd—unlike other methods of remote access to files via a remote shell, scp for example, which requires scp on the server side). Optionally, there can be a special FISH server program (called start_fish_server) on the server, which executes FISH commands instead of Unix shell and thus speeds up operations.

The protocol was designed by Pavel Machek in 1998 for the Midnight Commander software tool.

Protocol messages

Client sends text requests of the following form:

Fish commands are all defined, shell equivalents may vary. Fish commands always have priority: the server is expected to execute a fish command if it understands it. If it does not, however, it can try and execute a shell command. When there is no special server program, Unix shell ignores the fish command as a comment and executes the equivalent shell command(s).

Jasper Fish

Jasper Fish (buried 28 July 1791 at Sevenoaks, Kent) was a noted professional cricketer in the 18th century who was chiefly associated with Kent in the 1760s and 1770s.

Most of his career took place before cricket's statistical record began with regular scorecards in 1772 and he is recorded in only three major cricket matches in 1769, 1773 and 1777.

Fish anatomy

Fish anatomy is the study of the form or morphology of fishes. It can be contrasted with fish physiology, which is the study of how the component parts of fish function together in the living fish. In practice, fish anatomy and fish physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the latter dealing with how those components function together in the living fish.

The anatomy of fish is often shaped by the physical characteristics of water, the medium in which fish live. Water is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs more light than air does. The body of a fish is divided into a head, trunk and tail, although the divisions between the three are not always externally visible. The skeleton, which forms the support structure inside the fish, is either made of cartilage, in cartilaginous fish, or bone in bony fish. The main skeletal element is the vertebral column, composed of articulating vertebrae which are lightweight yet strong. The ribs attach to the spine and there are no limbs or limb girdles. The main external features of the fish, the fins, are composed of either bony or soft spines called rays, which with the exception of the caudal fins, have no direct connection with the spine. They are supported by the muscles which compose the main part of the trunk. The heart has two chambers and pumps the blood through the respiratory surfaces of the gills and on round the body in a single circulatory loop. The eyes are adapted for seeing underwater and have only local vision. There is an inner ear but no external or middle ear. Low frequency vibrations are detected by the lateral line system of sense organs that run along the length of the sides of fish, and these respond to nearby movements and to changes in water pressure.

Arca (producer)

Alejandro Ghersi, better known by his stage name Arca, is a Venezuelan record producer, consultant, mixing engineer and DJ based in Dalston, London.

Early life

Arca was born in 1990 in Caracas, Venezuela into a wealthy family. His father was an investment banker and his mother studied International Studies. His family moved to Connecticut for a time, before returning to live in a gated community, where he was privately educated and had the luxury of piano lessons. He describes his childhood as “kind of in a bubble”, and had difficulty accepting the fact that he was gay. He later attended the Clive Davis Institute of Recorded Music at NYU.

Career

In 2012, he released three EPs on the UNO NYC label: his debut as Arca, Barón Libre,Stretch 1, and Stretch 2.

In 2013, he lent additional production on four songs from the Kanye West sixth studio album Yeezus, in which he also served as one of the three production consultants along with Hudson Mohawke and Young Chop and as a producer on FKA Twigs' EP2. He self-released the &&&&& mixtape for free, and was involved in an audio-visual performance of &&&&& alongside Jesse Kanda, who contributed the visuals, at MoMA PS1 in October 2013.

ARCA Space Corporation

ARCA Space Corporation is an aerospace company based in Las Cruces, New Mexico that builds space rockets and other manned and unmanned aircraft intended for space exploration. It was founded in 1999 as a non-governmental organization in Romania by Dumitru Popescu and other rocket and aeronautics enthusiasts. Since then ARCA launched two stratospheric rockets, four large scale stratospheric balloons including a cluster balloon and was awarded two governmental contracts with the Romanian Government and one contract with the European Space Agency. ARCA is currently developing a suborbital rocket plane, an orbital and suborbital rocket family and a stratospheric unmanned aerial vehicle.

History

1999-2004: Demonstrator rocket family

ARCA was established as Romanian Cosmonautics and Aeronautics Association (Asociația Română pentru Cosmonautică și Aeronautică), an non-governmental organization in 1999 by a group of rocket and aeronautics enthusiasts. Their goal was to construct and launch space rockets. After experimenting with designs for different fuels and rocket engine types, including solid fuel rockets, they decided using fiberglass for engine and tank construction and hydrogen peroxide as fuel. Their first vehicle was named Demonstrator and was a 10 meter long, unguided, self stabilized rocket. It never flew, instead it was used in various public exhibitions to attract funds and sponsorships. Their second rocket, Demonstrator 2 was constructed in 2003. For this, ARCA created their first rocket engine testing installation where they tested their hydrogen peroxide engine. After the tests were successful they constructed Demonstrator 2B which was an improved version of their previous rocket. It had a 4.5 m length and 0.77 m diameter and used a 18 m high launch pad.
