Linux on embedded systems

Operating systems based on the Linux kernel are used in embedded systems such as consumer electronics. Thanks to their versatility, operating systems based on the Linux kernel can be found in mobile devices that are touchscreen-based embedded devices, such as smartphones and tablets, together with personal digital assistants and portable media players that include a touchscreen; this is a challenge for most learners because their computer experience is based on GUI based interaction with the machine and high-level programming on the one hand and low-level programming of small microcontrollers on the other hand while the concept of command line interfaces is unknown. The Linux kernel has been ported to a variety of CPUs which are not only used as the processor of a desktop or server computer, but ARC, ARM, AVR32, ETRAX CRIS, FR-V, H8300, IP7000, m68k, MIPS, mn10300, PowerPC, SuperH, Xtensa processors. Linux is used as an alternative to using a proprietary operating system and its associated toolchain.

The Embeddable Linux Kernel Subset is a Linux distribution that fits on a floppy disk for outdated or low resource hardware. Due to its low cost and ease of customization, Linux has been shipped in many consumer devices. Devices covering PDAs, TomTom GPS navigation devices, residential gateways like the Linksys WRT54G series or smartphones such as the Motorola exz series, Openmoko handsets, devices running Sailfish OS developed by Jolla like Jolla C and Intex Aqua Fish and the Nokia N900 and Nokia N9. Android, a Linux-kernel-based operating system acquired and extended by Google and introduced in 2008, has become a competitive platform for smartphones and tablets. In July 2012, Android's smartphone market share in the United States was at 52%, reaching 82% worldwide in Q2 2015. With the availability of consumer embedded devices, communities of users and developers were formed around these devices: replacement or enhancements of the Linux distribution shipped on the device has been made possible thanks to availability of the source code and to the communities surrounding the devices.

Due to the high number of devices, standardized build systems have appeared, including Yocto, OpenEmbedded, OpenWrt, LTIB. The advantages of embedded Linux over proprietary embedded operating systems include multiple suppliers for software and support; the technical disadvantages include a comparatively large memory footprint.

Mike Harrison (footballer, born 1952)

Michael Harrison is an English former professional footballer who made 19 appearances in the Football League playing for Birmingham City and Southend United. He played as a centre half. Harrison was born in Leicestershire; when he left school in 1968 he joined Birmingham City as an apprentice, turning professional two years later. He captained Birmingham's youth team, made his debut as an 18-year-old, deputising for Dave Robinson in a 4–1 win at Leicester City on 16 January 1971, he kept his place for the next game in the absence of Roger Hynd, played once more the following season in place of Stan Harland. In the 1972 close season Harrison joined Southend United, where he spent one season and played 18 games in all competitions, his next club was Yeovil Town of the Southern League. In the 1974–75 season, his second with the club, Harrison was named Player of the Year; the following season, under player-manager Stan Harland whom Harrison had understudied at Birmingham, the club achieved a "runners-up double" in the Southern League and the Southern League Cup, success which prompted invitation into the 1976–77 Anglo-Italian Semiprofessional Tournament, to play against Italian Serie C teams.

Harrison was again named Player of the Season. In all competitions, he made 304 appearances for Yeovil Town over a six-year career

European Parliament Committee on the Environment, Public Health and Food Safety

The Committee on the Environment, Public Health and Food Safety is a committee of the European Parliament. It has 69 full members, its current chair is Pascal Canfin. During the 1990s its low importance led to its being referred to unfavourably by MEPs as the "Cinderella committee". However, since the committee's powers have increased; the co-decision procedure for legislation, which grants greater powers to the Parliament, has been extended to more policy areas. Notably, the areas covered by this committee were the main recipients of these new powers; the rising importance of the issues it deals with has meant that it has become one of the most important committees in Parliament. The committee's open sessions, as well as constituting a major forum within the Parliament, are well attended by both business lobbyists and representatives from environmental NGOs; the committee is responsible for: 1. Environmental policy and environmental protection measures, in particular concerning: climate change, air and water pollution, waste management and recycling, dangerous substances and preparations, noise levels and the protection of biodiversity, sustainable development and regional measures and agreements aimed at protecting the environment, restoration of environmental damage, civil protection, the European Environment Agency, the European Chemicals Agency.

Public health, in particular: programmes and specific actions in the field of public health and cosmetic products, health aspects of bioterrorism, the European Medicines Agency and the European Centre for Disease Prevention and Control. Food safety issues, in particular: the labelling and safety of foodstuffs, veterinary legislation concerning protection against risks to human health.

Edinburgh Institution F.P.

Edinburgh Institution F. P. is a former Edinburgh rugby union club, formed as the Edinburgh Institution Former Pupils club. It was open to the former pupils of the Edinburgh Institution school; the side won the unofficial Scottish Championship twice. The Edinburgh Institution was a school in Edinburgh founded by Rev. Robert Cunningham in 1832. Cunningham a schoolteacher in Steele's Hospital and headmaster of George Watson's Hospital, was frustrated by the teachings of both schools. Cunningham felt, his institute would focus on Mathematics and Languages. In George Street, the Institute moved to Hill Street Queen St in Edinburgh; the Edinburgh Institution Former Players rugby union club was founded either in late 1871 or in 1872. R. M. Neill, the father of two Edinburgh Academical players, helped. Former rugby players of the Institution were plentiful but the side had difficulty attracting players. Many former players were playing their rugby for other clubs. For example John McFarlane captained Edinburgh University and Nat Brewis played for RHS FP.

J. J. Deuchar captained the side; as the team improved Nat Brewis took over the captaincy. Within ten years the club won the Scottish Unofficial Championship and was - together with Edinburgh Academicals and Glasgow Academicals - considered one of the top club sides in Scotland. Edinburgh Institution F. P. hosted their first rugby sevens tournament in 1921. The Edinburgh Institution moved from its premises in Queen St to Melville St. in Edinburgh in 1920. Shortly after this move, the Institution was renamed Melville College in 1936; the rugby union club was renamed Melville College FP. The following former Edinburgh Institution FP players have represented Scotland at full international level; the following former Edinburgh Institution FP players have represented Edinburgh District at provincial level.

Angolan flying squid

The Angolan flying squid is a species of squid from the subfamily Todarodinae, part of the familyOmmastrephidae. Due to taxonomic confusion with the Antarctic flying squid the exact limits of its distribution are uncertain but it is thought to be restricted to waters off Southern Africa; the Angolan flying squid has the typical cylindrical mantle shape of the Todarodine squids with arrow shaped fins. It does not have visceral photophores; the tentacular club has a short carpal area and has only four pairs of suckers, a number, distinct for this species. The suckers in the middle part of the manus have 13 to 16 long, pointed teeth on their rings there are 14-18 suckers on the manus arranged in four rows; the tentacles bear four rows of suckers, the largest of which have 14-17 conical teeth in their rings alternating with square plates. The rings of the suckers on the arms have large distal teeth which alternate with small teeth; the distal two fifths of the fourth right arm of males is hectocotylised and has thick pedicels rather than suckers which are entirely connected by the ventral protective membrane.

The body is a dark purplish brown in colour. The Angolan flying squid is found off Southern Africa in the south-eastern Atlantic Ocean in the Benguela Current off Angola and South Africa and it extends eastwards in to the Indian Ocean. However, some sources see taxonomic note below; the Angolan flying squid is found in the upper slope, benthic habitat of the South African continental slope at depths of between 300m and 500m, as is the lesser flying squid and these two species are considered indicator species for this zone. The adults are restiricted to near the bottom during the day while the juveniles occur in all depths apart from the surface, which they avoid during the day. During the night the adult squid move up the watercoilumn and can be found at various depths but still avoid the surface and the juveniles are most abundant at depths of 60m-80m; the youn squid show a preference for the epipelagic zone. In a population off Namibia the sex showed a clear predominance of females over males, observed in the congeneric European flying squid.

This may be due to differeing habitat preferences of males and females and that the only meet to spawn. The smallest mature male has a mantle length of the smallest mature female measured 250 mm. Studies of certain anatomical features suggest that females become sexually mature at mantle lengths of between 300mm to 350 mm The sub-adult and adult squid are most abundant during the Southern spring, from October to December. Analysis of statoliths suggest that the life span of this species is one year but growth rates are subject to considerable individual variation and are correlated variable environmental effects of the northern Benguela Upwelling System. Angolan flying squid are opportunistic predators and their prey includes a variety of fish species such as the Cape hake Merluccius capensis, in the northern Benguela Current, it is an important prey item for a number of predatory fish species sharks and marine mammals and may make up the majority of their diet. The Angolan flying squid is not directly targeted by fisheries but it is infrequently caught as bycatch in fisheries pursuing other species.

There is uncertainty in the distribution of the Angolan flying squid as there is some confusion over its true taxonomic position which has confused its separation from the Antarctic flying squid. This has led to some authorities describing it as circum global in the southern oceans but others in saying that it is restricted to the waters off Southern Africa
