Catfish

Catfish (pronounced kat-fish)

(1) Any of the numerous mainly freshwater teleost fishes of the order or suborder Nematognathi (or Siluroidei), characterized by barbels around the mouth and the absence of scales, especially the silurids of Europe and Asia and the horned pouts of North America.

(2) A wolffish of the genus Anarhichas.

(3) In casual use, any of various other fishes having a fancied resemblance to a catfish.

(4) In slang, a person who assumes a false identity or personality on the internet, especially on social media, usually with an intent to deceive, manipulate, or swindle.

(5) To deceive, swindle, etc by assuming a false identity or personality online.

(6) In casual use, any piece of machinery having a fancied resemblance to a catfish (and applied mostly to cars). 

1605–1615: The construct was cat + fish.  Dating from circa 700, cat was from the Middle English cat or catte and the Old English catt (masculine) & catte (feminine).  It was cognate with the Old Frisian and Middle Dutch katte, the Old High German kazza, Old Norse köttr, Irish cat, Welsh cath (thought derived from the Slavic kotŭ), the Russian kot and the Lithuanian katė̃; the Old French chat enduring.  The curious Late Latin cattus or catta was first noted in the fourth century, presumably associated with the arrival of domestic cats but of uncertain origin.  The Old English catt appears derived from the earlier (circa 400-440) West Germanic form which came from the Proto-Germanic kattuz which evolved into the Germanic forms, the Old Frisian katte, the Old Norse köttr, the Dutch kat, the Old High German kazza and the German Katze, the ultimate source being the Late Latin cattus.

The noun fish was from the pre-900 Middle English fish, fisch & fyssh, from the Old English fisc (fish), from the Proto-West Germanic fisk, from the Proto-Germanic fiskaz (fish).  It was cognate with the West Frisian fisk, the Dutch vis, the Old Norse fiskr, the Danish fisk, the Norwegian fisk, the Gothic fisks, the Swedish fisk and the German Fisch, the ultimate source probably the primitive Indo-European peys (fish) & pisk (a fish) although there are etymologist who speculate, on phonetic grounds, that it may be a north-western Europe substratum word.  It was akin to the Latin piscis, the Irish verb iasc, the Middle English fishen and the Old English fiscian, cognate with the Dutch visschen, the German fischen, the Old Norse fiska and the Gothic fiskôn.  The verb fish was from the Old English fiscian (to fish, to catch or try to catch fish).  It was cognate with the Old Norse fiska, the Old High German fiscon, the German fischen and the Gothic fiskon.  The plural is fishes, but in a collective sense, or in reference to fish meat as food, the singular fish generally serves for a plural, thus the noun plural of catfish tends to be catfish but zoologists and other specialists, especially when referring to two or more kinds or species, will tend to prefer catfishes.

The catfish seems to have gained its name early in the seventeenth century following the practice adopted for the Atlantic wolf-fish, noted for its ferocity, the catfish picking up its moniker apparently because of the "whiskers" although the "purring" sound it sometimes makes upon being taken from the water has (less convincingly) been suggested as the origin; most zoologists and etymologists prefer the whiskers story while noting the correct name for the appendages is barbels.

The modern term catfishing describes a type on nefarious on-line activity in which a person uses information and images, typically taken from others, to construct a new identity for themselves.  In the most extreme examples, a catfisher can steal and assume another individual’s entire identity, enabling the possibility of using the fake persona to engage in fraud or other illegal activities.  Catfishing attacks may be targeted or opportunistic and have long been common on dating sites.  One niche activity is where only a few (or legally insignificant) elements  are involved (usually in an attempt to tempt younger subjects on dating sites) and there is no attempt to engage in illegal activity; this has been called kitten fishing.

There is nothing new in the concept of catfishing, cases documented in the literature for centuries, the ubiquity of the internet just making such scams both easier to execute and easier to detect.  The term in this context is derived from the 2010 American documentary Catfish, which concerned a 26 year old man who, thinking he was building an on-line relationship with a 19 year old woman, discovered his digital interlocutor was actually a married women of 40.  The documentary (and thus the on-line behavior) gained the name from a mention the woman's husband made when comparing his wife’s conduct to the myth that it was once the practice to include one or more catfish in the tank when shipping live cod, the rationale said to be the cod would remain active in the presence of codfish whereas if shipped alone, would become pale and lethargic, reducing the quality of the flesh.  The source of the myth was the 1913 psychological novel Catfish by Charles Marriott (1869-1957), the fanciful story repeated that same year by Henry Wooded Nevinson (1856-1941) in his political treatise, Essays in Rebellion.

Etymologically unrelated (although not wholly dissimilar in practice) was the earlier internet slang phishing which described a kind of social engineering in which an attacker sends a deceptive message designed to trick a person into revealing sensitive information or induce them in some way to install malicious software such as key-stroke grabbers or ransomware.  Phishing is a leetspeak variant of fishing which compares the digital activity to actual angling, the idea being the casting of lines with lures in the hope there will be bites at the bait.  The first known reference to phishing dates from 1995 but there was apparently an earlier mention in the magazine 2600: The Hacker Quarterly, the word coined following the earlier phreaking.  Phishing has for years been the most common attack performed by cybercriminals.

Catfish and some cars they inspired.

First seen on a few eccentric examples during the 1930s, the distinctive, if not always pleasing “catfish look” emerged on volume production automobiles during the 1950s.  Even then the look was a stylistic curiosity but it was an age of extravagance and among the macropteric creations of the era, the catfish cars represented just one of many directions the industry could have followed.  Nor was the catfish look wholly without engineering merit, the low bonnet (hood) line improving aerodynamic efficiency, the wide, gaping aperture of the grill permitting adequate air-flow for engine cooling with headlamps able still to satisfy regulatory height requirements.  Classic examples of catfish styling includes the original Citroen DS (top left) , the Packard Hawk (top centre) and the Daimler SP250 (top right).

Daimler SP250 (1959-1964).

The Daimler SP250 was first shown to the public at the 1959 New York Motor Show and there the problems began.  Aware the little sports car was quite a departure from the luxurious but rather staid lineup Daimler had for years offered, the company had chosen the pleasingly alliterative “Dart” as its name, hoping it would convey the sense of something agile and fast.  Unfortunately, Chrysler’s lawyers were faster still, objecting that they had already registered Dart as the name for a full-sized Dodge so Daimler needed a new name and quickly; the big Dodge would never be confused with the little Daimler but the lawyers insisted.

Using one of his trademark outdoor settings, Norman Parkinson (1913-1990) photographed model Suzanne Kinnear (b 1935) adorning a Daimler SP250, wearing a Kashmoor coat and Otto Lucas beret with jewels by Cartier.  The image was published on the cover of Vogue's UK edition in November 1959.

Imagination apparently exhausted, Daimler’s management reverted to the engineering project name and thus the car became the SP250 which was innocuous enough even for Chrysler's attorneys and it could have been worse.  Dodge had submitted their Dart proposal to Chrysler for approval and while the car found favor, the name did not and the marketing department was told to conduct research and come up with something the public would like.  From this the marketing types gleaned that “Dodge Zipp” would be popular and to be fair, dart and zip(p) do imply much the same thing but ultimately the original was preferred and Darts remained in Dodge’s lineup until 1976, for most of that time one of the corporation's best-selling and most profitable lines.  The name was revived between 2012-2016 for an unsuccessful and unlamented compact sedan.

1962 Daimler SP250 (B-Spec).

Daimler’s SP250 didn’t enjoy the same longevity, the last of the 2654 produced in 1964, sales never having approached the projected 3000 per year, most of which were expected to be absorbed by the US market.  The catfish styling probably didn’t help, a hint being the informal poll taken at the 1959 show when the thing was voted “the ugliest car of the show” but under the skin of the ugly duckling was a virile swan.  The heart of the SP250 was a jewel-like 2.5 litre (155 cubic inch) hemi-headed V8 which combined the structure of Cadillac’s V8 with advanced cylinder heads which owed much to those of the Triumph Thunderbird motorcycle engine.  Indeed, the designer, Edward Turner (1901–1973), owned a Cadillac and was responsible for the Triumph heads so the influences weren’t surprising and the little engine had an interesting gestation.  It was Turner’s first car engine and so tied was he to the principles which had proved so successful for his motorcycles that the original concept was air-cooled and fed by eight carburetors.  Automotive reality however prevailed and what emerged was a compact, light (190 KG (419 lb)), water-cooled V8 with the inevitable twin SU carburetors, the project yielding also an only slightly bulkier (226 KG (498 lb)) 4.6 litre (278 cubic inch) version which would be tragically under-utilized by a British motor industry which could greatly have benefited from a wider deployment of both instead of some engines which proved pure folly.  The Daimler V8s are notable too for their intoxicating exhaust notes, perhaps not a critical aspect of engineering but one which adds much to the pleasure of ownership.

Under-capitalized and lacking the funds needed to revitalize their dated range, let alone develop new high-volume models, the SP250 was created on a shoestring budget, the body built in the then still novel fibreglass, not by deliberate choice but because the tooling and related production facilities could be fabricated for a fraction of the cost had steel or aluminum been used.  It also lessened the development time and promised a simpler and cheaper upgrade path in the future but also brought problems of its own.  New to the material, Daimler’s engineers were confronted with many of the same problems which Chevrolet encountered during the early days of the Corvette, issues which even with the vast resources of General Motors, proved troublesome.  Other than the fibreglass body, the SP250 was technologically conventional, using a chassis little different from that of the Triumph TR3, built in a 14 gauge box section with central cruciform bracing.  The chassis was designed to be light and that was certainly achieved but at the cost of structural rigidity, again an issue of the use of fibreglass, the engineers (in pre-CAD times) under-estimating the stiffness which would be demanded in a structure without metal panels further to distribute the loadings. 

1962 Daimler SP250 prepared for competition in British Racing Green (BRG) with factory hardtop and Minilite wheels.

The lack of sufficient torsional rigidity meant the SP250s were beset with the same teething problem as the first Corvettes: the fibreglass panels could become crazed or even crack and, most disconcertingly, doors were prone to springing open during brisk cornering and the bonnet (hood) sometimes popped open as the body flexed at high speed.  The SP250 was a genuinely fast car so these were not minor issues.  Still, there was much to commend the SP250.  Wind-up windows and the availability of an automatic transmission sound hardly ground-breaking but they were an innovation unknown on the MG, Triumph and Austin-Healy roadsters of the time and the V8 was unique.  The suspension was conventional but competent, an independent front end with upper and lower arms, coil springs, and telescopic shock absorbers while the rear used semi-elliptic leaf springs with lever arm shock absorbers.  The unassisted cam and peg system steering lacked the precision the Italians achieved even without using a rack and pinion system but, aided by a larger than usual steering wheel, it offered a reasonable compromise for the time although at low speed it was far from effortless.  More commendable were the brakes.  The four-wheel discs had no power assistance but the SP250 was a light car and the servo systems of the time, lacking feel and impeding the progressiveness inherent in the design of the early discs, meant unassisted systems were preferable for sports cars although, efficient and fade-free though they were, an emergency stop from speed did demand high pedal effort.  One curiosity in the configuration was the bumper bars.  Considering the issue bumpers would become in the 1970s, that they were once optional is an indication of how different the regulatory environment was at the time. The A spec SP250s had no bumpers as standard equipment but were fitted at the front with what are sometimes mistakenly called nerf-bars but are actually “bumperettes” although the English seem to like “whiskers”. At the rear were over-riders attached to nerf-bars. The B spec models didn’t include these but, like the A spec, the full bumpers were an optional extra and this setup was continued for the C spec. The SP250s used by the British Metropolitan Police as high speed pursuit cars always had the optional bumpers because of the need to mount the warning bell and auxiliary spotlight.

So, developed to the extent possible with the resources available, production began in 1959, shortly before the Birmingham Small Arms Company (BSA) announced the sale of Daimler to Jaguar.  Jaguar, attracted by Daimler’s extensive manufacturing facilities and its skilled workforce regarded most of the Daimler range as antiquated but allowed some production to continue although their engineers decided the chassis of the SP250 needed significant modifications to improve rigidity.  The strengthening was undertaken and the revised cars became known as the “B” models, the original 1959-1960 versions retrospectively labeled as A-Spec.  The changes were actually not extensive, a steel box section hoop added to connect the windscreen pillars, two steel outrigger sill beams along each side of the chassis, complimented with a couple of strategically placed braces.  The stiffer structure solved the problems and improved the driving experience, the B-spec cars produced between 1960-1963.  A subsequent upgrade, dubbed C-spec included some features such as a cigar lighter and a heater/demister and in this form, the cars remained in production until 1964.

Daimler SP252 prototype (1964)

Unfortunately, Jaguar was never enthusiastic about Daimler except as a badge which could be used on up-market Jaguars sold at a nice profit.  However, whatever the opinions of the catfish styling, the SP250 had proved itself in motorsport and, capable of a then impressive 122 mph (196 km/h), had been used as a high-speed pursuit vehicle by a number of police forces, interestingly usually with an automatic transmission, the choice made in the interest of reduced maintenance, a conclusion rental car companies would soon reach.  For that reason, the potential was clear and Jaguar explored a way to extend the appeal with a restyled body.  The result was the SP252, rendered still in fibreglass but now more elegantly done, hints of both the MGB and Jaguar E-Type (XK-E) while the rear owed some debt to Aston Martin’s DB4.  Aesthetically accomplished though it was, economic reality prevailed.  The factory was tooled-up to produce no more than 140 of the V8 engines each week, demand for which was already exceeding supply since it had been offered in the Jaguar Mk2-based Daimler 2.5 (later 250) saloon and Jaguar lacked the production capacity even to make enough E-types to meet demand.  Given that and the engineering resources it required to devote to the new V12 engine and the XJ6 saloon for which it was intended, another relatively low-volume project couldn’t be justified.

Jaguar missed an opportunity by not making better use of the Daimler V8s.  The smaller unit could have been enlarged to 2.8 litres to take advantage of the taxation rules in continental Europe and in the XJ would have been a more convincing powerplant than the 2.8 XK six which was always underpowered and prone to overheating.  When fitted to a prototype Jaguar Mark X, the 4.6 litre V8 had proved outstanding and, easily able to be expanded beyond five litres, it would have been ideal for the lucrative US market and the thought of a 4.6 V8 E-Type (XKE) remains tantalizing.  Unfortunately, Jaguar was besotted with the notion of the V12 and it wasn't until the 1990s they admitted what was needed was a 4-5 litre V8, the very thing they'd acquired with the purchase of Daimler in 1960.   

Produced between 1955-1975, the Citroën DS, although long regarded as something quintessentially French, was actually designed by an Italian.  In this it was similar to French fries (actually invented in Belgium) and Nicolas Sarközy (b 1955; President of France 2007-2012), who first appeared in the same year as the shapely DS and was actually from here and there.  It was offered as the DS and the lower priced, mechanically simpler ID, the names apparently an deliberate play on words, DS in French pronounced déesse (goddess) and ID idée (idea).  The goddess nickname caught on though idea never did; a curiously configured version built exclusively for the UK market was called the DW which appears to have meant nothing in particular.  The frontal aspect, combined with the efficiency of the rest of the body, delivered outstandingly good aerodynamics but the catfish look was tempered a little because the low, gaping grill associated with the motif well-concealed, reputedly because the ancient engine, a long-stroke, agricultural relic of the 1930s, produced so little power there wasn’t enough surplus energy to induce overheating, the need for a cooling flow of air correspondingly low.  That’s wholly apocryphal but later progress in design anyway softened the catfish effect.  It was most obvious on the series 1 cars (top) which were made between 1955-1962.  The Series 2 changes (1964-1967; centre) were effected further to improve aerodynamics and permitted also some increase to the airflow ducted for interior ventilation; the changes in appearance were said to be incidental to the process.  The catfish look vanished entirely when the series 3 cars (bottom) were introduced in 1967.

Now with four headlamps mounted behind glass canopies, the shape of which was integrated into the front fenders (top left), the arrangement was noted for the novelty of the inner set of lens being controlled by the steering (top right), the light thus being projected “around the corner” in the direction of travel, swiveling by up to 80°.  It was a simple, purely mechanical connection and the idea had during the 1930s used with auxiliary driving or fog-lights and the central (Cyclops) unit on the abortive Tucker Torpedo (1948) had been configured the same way but the DS was the first car to use adaptive headlights in volume.  Both the covers and the turning mechanism fell afoul of US regulations (lower left) so there the lens were fixed and exposed.  Another variation was in Scandinavia where miniature wipers were sometimes fitted to conform with local law.  In the collector market, the small feature can add a remarkable premium to the value of a car, rare factory options highly sought.

1958 Packard Hawk

Fittingly perhaps, the gaping-mouth of the catfish style was applied to what proved one of the last gasps for Packard, a storied marque with roots in the nineteenth century which in the inter-war years had been one of the most prestigious in the US and it had been the sound of the V12 Packards which inspired Enzo Ferrari (1989-1988) to declare Una Ferrari è una macchina a dodici cilindri (a Ferrari is a twelve cylinder car).  The appeal was real because it was a 1936 Packard phaeton Standard Eight which comrade Stalin (1878-1953; Soviet leader 1924-1953) used as his parade car and the ZiS-115 limousine (1948-1949 and based on the ZiS 110 (1946-1958), all better known in the West as ZILs) he used in his final years was a reversed-engineered (ie copy) version of the 1942 Packard.  Reverse-engineering was a notable feature of Soviet industry and much of its post-war re-building of the armed forces involved the process, exemplified by the Tupolev Tu-4 heavy bomber (1947) which was a remarkably close copy of the US Boeing B-29 (1942).  Other countries also adopted the practice which in some places continues to this day for mot civilian and military output.  After spending World War II engaged in military production, notably a version of the Merlin V12 aero-engine built under license from Rolls-Royce, Packard emerged in 1945 in sound financial state but found the new world challenging, eventually in 1953 merging with fellow struggling independent, Studebaker.  Beset with internal conflicts from the start, things went from bad to worse and after dismal sales in 1958-1959 of the final Packards (which were really modified Studebakers and derided by many as "Packardbakers"), the Packard brand was retired with the coming of 1959.  The Studebaker-Packard Corporation in 1962 reverted to again become Studebaker but it was to no avail, the last Studebaker being produced in 1967.

The mashup of period styling motifs (fins, dagmars, curved glass, scallops & scoops) on the 1958 Packard was not untypical in the era and the catfish treatment at the front was really the most restrained part of the package.     

1957 Studebaker Golden Hawk.  Whatever the criticism of the catfish-like Packard, the car on which it was based was perhaps even more ungainly.

The origins of Packard’s swansong, the Hawk, lay in a 1957 Studebaker Golden Hawk 400 which was customized in-house for executive use.  The front end and bonnet (hood) were rendered in fiberglass, eliminating the familiar upright grille and small side inlets which were replaced with the low, wide air intake so characteristic of the catfish look.  Covering all bases, for those unconvinced by the catfish look, a pair of modest (by Cadillac standards) dagmars were added.  Because the engine was supercharged, like the Studebaker, the hood included a bulge but because of the lower lines, it rose higher on the Packard.  Lacking the funds to create anything better, the Hawk was approved for production as a standard 1958 model but it was from the start doomed.  It was expensive and its debut coincided with the recession of that year when all auto-makers suffered downturns but, with the rumors swirling of Studebaker-Packard's impending demise, Packard suffered more than most and only 588 Hawks were built.

1958 Packard 

Packard’s rather plaintive swansong was another set of cobbled-together Packardbakers, available as a two-door hardtop and a four-door sedan or wagon.  In 1958, fins were a thing at the rear but what really exited the stylists was that quad headlamps were now permitted in all 48 states.  Unlike the majors however, the corporation had no funds to re-tool body dies to accommodate the change so hurriedly, fibreglass pods were created which when fitted, looked as tacked-on as they really were.  Also tacked on were the new fins which sat atop the old although these were at least genuine steel rather than fibreglass.

1958 Chrysler Royal (AP2) and 1960 Chrysler Royal (AP3) (Australian)

They were also definitely always standard equipment on all the Packards, unlike the 1958 Australian Chrysler Royal (AP2) which featured similar appendages grafted to pre-existing fins, Chrysler listing them as an optional extra called "saddle fins".  However, no Royal apparently was sold without saddle fins attached so either (1) they were very popular option or (2) Chrysler changed their mind after the promotional material was printed and decided to invent mandatory options, a marketing trick Detroit would soon widely (and profitably) adopt.  In 1960, the Australians also solved the problem of needing to add quad headlamps without either a re-tool or plastic pods, changing instead the grill and mounting the lights in a vertical stack, an expedient Mercedes-Benz had recently used to ensure their new W111 (Heckflosse) sedans satisfied US legislation.

Thunk

Thunk (pronounced thunk)

(1) Onomatopoeic slang for sounds such as the impressive thud when the doors close on pre-modern Mercedes-Benz; representing the dull sound of the impact of a heavy object striking another and coming to an immediate standstill, with neither object being broken by the impact.

(2) In computer programming, a delayed computation (known also as a closure routine.

(3) In computing, in the Scheme programming language, a function or procedure taking no arguments.

(4) In computing, a specialized subroutine in operating systems where one software module is used to execute code in another or inject an additional calculation into another subroutine; a mapping of machine data from one system-specific form to another, usually for compatibility reasons, to allow a 16-bit program to run on a 32-bit operating system.

(5) In computing, to execute code by means of a thunk.

(6) As “get thunked” or “go thunk yourself”, an affectionate insult among the nerdiest of programmers.

(7) In colloquial use, a past tense form of think (the standard form being "thought").  Usually it's used humorously but, if erroneous, it's polite not to correct the mistake.

1876: The first documented instance as incorrect English is from 1876 but doubtlessly it had been used before and there’s speculation it may have be a dialectical form in one or more places before dying out.  There being no oral records and with nothing in writing prior to 1876, the history is unknown.  As an echoic of the sound of impact, it’s attested from 1952.  Although occasionally heard in jocular form, except in computing, thunk is non-standard English, used as a past tense or past participle of think.  The mistake is understandable given the existence of drink/drunk, sink/sunk etc so perhaps it’s a shame (like brung from bring) that it’s not a standard form except in computing.  The plural is thunks, the present participle thunking and the simple past and past participle thunked.  The numerical value of thunk in Chaldean Numerology is 4; the value in Pythagorean Numerology is 2.

Getting thunked

The origin of the word to describe a number of variations of tricks in programming is contested, the earliest dating from 1961 as onomatopoeic abstractions of computer programming.  One holds a thunk is the (virtual) sound of data hitting the stack (some say hitting the accumulator).  Another suggestion is that it’s the sound of the expression being unfrozen at argument-evaluation time. The most inventive in that it was said to have been coined during an after-midnight programming session when it was realized a type of an argument in Algol 60 could be figured out in advance with a little compile-time thought, simplifying the evaluation machinery.  In other words, it had "already been thought of"; thus it was christened a "thunk", which is “the past tense of ‘think’ at two in the morning when most good programming is done on a diet of Coca-Cola and pizza”.


Door closing on 1967 Mercedes-Benz 230 S.  Until the 1990s, the quality of even the low-end Mercedes-Benz models was outstanding.

Thunking as a programming concept does seem to have been invented in 1961 as “a chunk of code which provides an address”, a way of binding parameters to their formal definitions in procedure calls.  If a procedure is called with an expression in the place of a formal parameter, the compiler generates a thunk which computes the expression and leaves the address of the result in some standard location.  It usefulness was such it was soon generalised into: an expression, frozen with its environment for later evaluation if and when needed (that point being the closure), the process of unfreezing thunks called forcing.  As operating systems evolved into overlay-rich environments, the thunk became a vital stub-routine to load and jump to the correct overlay, Microsoft and IBM both defining the mapping of the 16-bit Intel environment with segment registers and 64K address limits whereas 32 & 64-bit systems had flat addressing and semi-real memory management.  Thunking permits multiple environments to run on the same computer and operating system and to achieve this, there’s the universal thunk, the generic thunk and the flat thunk, the fine distinctions of which only programmers get.  In another example of nerd humor, a person can be said to have their activities scheduled in a thunk-like manner, the idea being they need “frequently to be forced to completion”, especially if the task is boring.

Lindsay Lohan and her lawyer in court, Los Angeles, December 2011.

So it’s a bit nerdy but modern operating systems need thunking because 8, 16, 32 and 64-bit routines can need to run both concurrently and interactively on the same machine (real or virtual).  If a 32-bit application sends something with precision data types to a 64-bit handler, without thunking, the call will fail because the precise address can’t be resolved.  Although not literally true, it’s easiest to visualise thunking as a translation layer.

IBM OS/2 2.0 in shrink-wrap, 1992.

Thunking first entered consumer computing at scale with IBM’s OS/2 in 1987, an operating system still in surprisingly wide use and supported by IBM until early in the century.  Interestingly, although both OS/2 (and its successor eCom) have been unavailable for years, in August 2017, a private project released ArcaOS, an x86 operating system derived from OS/2 and, for personal use, it retails at US$129.00.  Like OS/2, it has some features which are truly unique such as, for the handful of souls on the planet who either need or wish simultaneously to run multiple 8, 16 and 32-bit text-mode sessions, (including those internally booting different operating systems in segregated memory) in their hundreds on the one physical machine.  First done in 1992 on OS/2 2.0, it’s still quite a trick and the on-line OS/2 Museum hosts an active community, development continuing.

Corduroy

Corduroy (pronounced kawr-duh-roi)

(1) A cotton-filling pile fabric with lengthwise cords or ridges.

(2) In the plural as corduroys (or cords), trousers made from this fabric.

(3) Of, relating to, or resembling corduroy.

(4) A method of building an improvised road or causeway, constructed with logs laid together transversely (used by military forces, those operating in swampy ground areas etc); the result was described originally as “ribbed velvet” and when intended for sustained use, earth was thrown into the gaps and compacted, thus rendering a relatively smooth, stable surface.

(5) To form such a “road” by arranging logs transversely.

(6) In ski-run maintenance, a pattern on snow resulting from the use of a snow groomer to pack snow and improve skiing, snowboarding and snowmobile trail conditions (corduroy thought a good surface for skiing).

(7) In Irish slang, cheap, poor-quality whiskey (based on the idea on the fabric corduroy not being “smooth”.

1776: Of uncertain origin.  There’s no consensus among etymologists but the most support seems to be for the construct being cord + duroy (one of a number of lightweight, worsted fabrics once widely produced and known collectively as “West of England Cloth”).  Cord (A long, thin, flexible length of twisted yarns (strands) of fiber) was from the late thirteenth century Middle English corde (a string or small rope composed of several strands twisted or woven together; bowstring, hangman's rope), from the Old French corde (rope, string, twist, cord), from the Latin chorda (string of a musical instrument, cat-gut), from the Doric Ancient Greek χορδά (khordá) (string of gut, the string of a lyre) and may be compared with the Ionic χορδή (khord), from the primitive Indo-European ghere- (bowel; intestine).  The adjective cordless (of electrical devices or appliances working without a cord (ie powered by a battery) dates from 1905 and was augmented later by “wireless” which described radios so configured.  Cordless is still a useful word now that the meaning of “wireless” in the context of computing has become dominant.  The curious use of cord as “a unit of measurement for firewood, equal to 128 cubic feet (4 × 4 × 8 feet), composed of logs and/or split logs four feet long and none over eight inches diameter (and usually seen as a stack 4 feet high by 8 feet long)” dates from the 1610s and was so-called because it was measured with a cord of rope marked with the appropriate measures.

Until well into the twentieth century, the old folk etymology was still being published which held the word was from the French corde du roi (cloth of the king”), which seems never to have be used in France, the correct term for “cloth of the king” being velours côte.  It’s not impossible there’s some link with cordesoy, from the French corde de soie (“rope of silk” or “silk-like fabric”) because that form is documented in an advertisement for clothing fabrics dating from 1756.  The spelling corderoy appears in commercial use in 1772 but the modern “corduroy” became the standard form in the 1780s.  The origin of duroy is obscure and the earliest known use (in print) of the word appeared in the early seventeenth century; it may be from the French du roi (of the king), a 1790 trade publication in France including the term duroi (a woolen fabric similar to tammy).  So, although the case for cord + duroy seems compelling, etymologists note (1) duroy was fashioned from wool while corduroy was made with cotton and there’s no other history of the two words being associated, (2) grammatically, the compound should have been duroy-cord and (3) this does not account for the earlier corderoy.

None of that of course means cord + duroy was not the source and many English words have been formed in murky ways.  There’s also the possibility of some link with the English surname Corderoy (although there is no evidence of a connection); the name was also spelt Corderey & Cordurey, the origin lying in the nickname for “a proud person” (of French origin, it meant “king’s heart”).  Some are more convinced by a suggestion made in 1910 by the English philologist Ernest Weekley (1865-1954) who speculated corduroy began life as folk-etymology for the trade-term common in the sixteenth century: colour de roy, from the French couleur de roi (king’s colour) which originally was a reference to both a cloth in the rich purple associated with the French kings and the color itself. Later, it came to signify a bright tawny colour and a cloth of this hue.  Corduroy as an adjective came into use after 1789 and the use to describe roads or causeways improvised by means of with logs laid together transversely (usually to provide wheeled vehicles passage over swampy ground dates from the 1780s.  Corduroy is a noun, verb & adjective, corduroying & corduroyed are verbs and corduroylike is an adjective; the noun plural is corduroys.

By the 1960s most Mercedes-Benz were being trimmed in their famously durable MB-Tex, a robust vinyl which was not only easy to maintain but closely resembled leather, lacking only the aroma (and third-party manufacturers soon made available aerosols for those who found the olfactory appeal too much to forgo).  However, leather and velour (of mohair in the most exclusive lines) were either standard or optional on more expensive models and when exported to first-world markets beyond Europe (such as North America or Australia), MB-Tex or leather was standard and the fabrics were available only by special order.  A notable exception was the Japanese market where buyers disliked the way their prized “car doilies” slid of the hide; they always preferred cloth.  The velour was certainly better suited to harsh northern European winters and testers would often comment on how invitingly comfortable were the seats trimmed in the fabric.  To add to the durability, the surfaces subject to the highest wear (ie those at the edges on which there was the most lateral movement during ingress and egress) used a corduroy finish (the centre panels also trimmed thus, just for symmetry).

Bedchamber

Bedchamber (pronounced bed-cheym-ber)

A now archaic word for bedroom; the alternative form was bed-chamber.

1325–1375:  From the Middle English bedchaumbre, the construct being bed + chamber.  Bed was from the Middle English bed or bedde, from the pre-1000 Old English bedd (bed, couch, resting-place; garden-bed, plot), from the Proto-Germanic badją (plot, grave, resting-place, bed) and thought perhaps derived from the Proto-Indo-European bhed (to dig).  It was cognate with the Scots bed and bede, the North Frisian baad and beed, the West Frisian bêd, the Low German Bedd, the Dutch bed, the German bett, the Danish bed, the Swedish bädd, the Icelandic beður and perhaps, (depending on the efficacy of the Proto-Indo-European lineage), the Ancient Greek βοθυρος (bothuros) (pit), the Latin fossa (ditch),the Latvian bedre (hole), the Welsh bedd (grave), the Breton bez (grave).  Any suggestion of links to Russian or other Slavic words is speculative.

Chamber dates from 1175-1225 and was from the Middle English chambre, borrowed from Old French chambre, from the Latin camera, derived from the Ancient Greek καμάρα (kamára) (vaulted chamber); the meaning “room”, usually private, drawn from French use.  As applied to anatomy, use emerged in the late fourteenth century; it was applied to machinery in 1769 and to ballistics from the 1620s.  The meaning "legislative body" is from circa 1400 and the term chamber music was first noted in 1789, not as a descriptor of any musical form but to indicate that intended to be performed in private rooms rather than public halls.

The Bedchamber Crisis, 1839

A Lady of the Bedchamber, a position held typically by women of noble descent, is a kind of personal assistant to the Queen of England.  A personal appointment by the Queen, they’ve existed for centuries, their roles varying according to the relationships enjoyed.  Most European royal courts from time-to-time also adopted the practice.

The 1839 bedchamber crisis is emblematic of the shifting of political power from monarch to parliament.  Although the eighteenth-century administrative and economic reforms created the framework, it was the 1832 Reform Act which, in doing away with a monarch’s ability to stack parliaments with ample compliant souls, shattered a sovereign’s capacity to dictate election results and within two years the new weakness was apparent.  In 1834, William IV (1765–1837; King of the UK 1830-1837)  dismissed the Whig Lord Melbourne (1779–1848; Prime Minister of the UK 1834 & 1835-1841) and appointed the Tory Sir Robert Peel (1788–1850; Prime Minister of the UK 1834–1835 & 1841–1846).  However, the King no longer enjoyed the electoral influence necessary to secure Peel a majority in the Commons and after being defeated in the house six times in as many weeks, the premier was obliged to inform the palace of his inability to govern, compelling the king to invite Melbourne to form a new administration, one which endured half a decade, out-living William IV.  The king's exercise in 1834 of the royal prerogative proved the last time the powers of the head of state would be invoked sack a prime-minister until an Australian leader was dismissed in 1975 by the governor-general (and in a nice touch the sacked PM had appointed the clearly ungrateful GG).

By 1839, Melbourne felt unable to continue and the new Queen Victoria (1819–1901; Queen of the UK 1837-1901), reluctantly, invited Sir Robert Peel to assume the premiership, a reticence some historians attribute as much to her fondness for the avuncular Melbourne as her preference for his Whig (liberal) politics.  Peel, knowing any administration he could form would be nominally in a minority, knew his position would be strengthened if there was a demonstration of royal support so asked Victoria, as a gesture of good faith, to replace some of the Whig Ladies of the Bedchamber with a few of Tory breeding.  Most of the ladies were the wives or daughters of Whig politicians and Sir Robert’s request made sense in the world of 1839.

Victoria rejected his request and prevailed upon Melbourne to continue which he did, until a final defeat in 1841.  By then it was clear only Peel could command a majority in the Commons and he insisted on his bedchamber cull, forcing Victoria to acquiesce to the parliament imposing on her the most intimate of her advisors.  This is the moment in constitutional history where the precedent is established of the parliament and not the Crown determining the formation and fate of governments.  Since then, the palace can warn, counsel and advise but not compel.
