However, addressing accessibility concerns is not simply a matter of increasing the contrast ratio. As a report to the Web Accessibility Initiative indicates, dyslexic readers are better served by contrast ratios below the maximum. The recommendations they refer to of off-black (0x0A0A0A) on off-white (0xFFFFE5) and black (0x000000) on creme (0xFAFAC8) have contrast ratios of 11.7:1 and 20.3:1 respectively. Among their other color pairs, brown (0x282800) on dark green (0xA0A000) has a contrast ratio of 3.24:1, which is less than the WCAG recommendation, dark brown (0x1E1E00) on light green (0xB9B900) has a contrast ratio of 4.54:1 and blue (0x00007D) on yellow (0xFFFF00) has a contrast ratio of 11.4:1. Notice that the colors named in the report use different color values than the web colors of the same name.

Monetising unpaid effort controversies

Hobby clubs may have to prove their members efforts exceed their income in value terms, so as to remain tax-exempt. I've not heard of any controversies or scandals in this area but I'm sure there will be people somewhere looking for ways to extract money from this.

There used to be a Wikipedia Money, but it died the death, and I can't find the reference. A candidate referred to it (dismissively) in a Wikipedia election candidature submission. It's not the Wiki Credit nor the Bounty board (historical, and see its talk page). Saying this "money" can't be extracted; it can only be used in a Wikipedia project, is naïve. This is true only up until someone who has accumulated some Wikipedia Money offers to expend it on a project of interest to another user in exchange for some real money.

There doesn't yet exist a List of controversies around monetisation of the work of unpaid contributors.

Monetising unpaid effort is also the motivation behind attempts to take over or control various forms of free (libre) software.

Being able to take over the commons that result is part of the difference between GPL (particularly v.3) and MIT licenses, with some recent controversies about the GPL being directed at ways to open up attempts to take over the commons.

Geometry of convoluted wye
Meeting point of tangents all at centre of bounding circle for switches (circle geometry & tangents). Overall diameter is this circle + 2 x headshunts.

2 tangents to a circle from a point outside the circle are equal in length, so the multiple tangents of a convoluted wye will be radii of a circle.

Example calculations showing space savings. A detailed diagram.

Publish relevant .svg diagrams to Commons, plus .png equivalents because .svg diagrams aren't fully handled by Wikimedia.

Any number of arms are possible for a convoluted wye but even numbers leave the vehicle facing the same way, so are pointless. Odd numbers of seven or more arms will turn the vehicle but any additional saving of space is unlikely to be worth the additional complication.

Examples at 7 and calculate space.

Heading - Geometry of a convoluted wye

Symmetric case initially. Adjacent tangent extensions to meeting point are equal, ∴ all are equal. Meeting points of tangents, therefore (∴) all switch curves are inside a bounding circle with centre where tangents meet.

For a symmetric wye of either type, regular 3-arm or convoluted 5-arm, each headshunt is a tangent to the circle arc formed by the switch curve. If the tangents are extended in the other direction to the centre of the wye (dashed lines on the diagram) they will meet and, because each pair of headshunt tangents are tangents to a circle from a point outside the circle they are equal in length. This is true for all the pairs, so they are all equal in length and are radii of the circle containing all the switch curves (dashed circle on the diagram).

Each dashed line tangent extension meets the radius of the switch curve circle at a right angle (property of a tangent), so the triangle formed by the dashed line extension of the tangent, the radius at the tangent and a line from the centre of the switch curve circle to the meeting of the tangent lines is a right-angle triangle. Because of this, the radius of the dashed circle containing the switch curves is the radius of the switch curve &times; the tangent of half the angle between the radii of the switch curve circle. This is 32° for a 5-way convoluted wye (360° ÷ 5 ÷ 2) or 60° for a 3-way regular wye (360° ÷ 3 ÷ 2).

The half angle is 180° / (2 * the armcount) (need to re-check which is the angle and which is the half-angle).

Need a diagram to demonstrate the preceding explanation and calculation, and make the whole thing clearer.

Heading - Size of a symmetric convoluted wye

The size of a symmetric wye is size of the switch curve bounding circle plus the headshunt lengths. For a 5-way convoluted wye its diameter is twice the radius of the switch bounding circle plus twice the headshunt length. The same is true of a regular 3-way wye, but the angle of the switch curve is different.

A suitable headshunt length is 30 m. Allowing 2 m for a buffer stop plus 2 &times; 1 m of manoeuvring room either side of the engine is a total of 4 m so this leaves 26 m for the engine. This is enough to accomodate such engines as an FS Class 740 (20 m with bogie tender), an FS Class 746 (23 m), an FS Class 691 (23 m), a DRB Class 50 (23 m), an État 3701 to 3755 series (16.2 m), an SNCF Class 141R (24.2 m), an LMS Coronation Class (23 m), an LNER Gresley Class A1 or A3 (22 m) and so on with space to spare.

For switch curve radii of 190 m and 300 m (the approximate radii of class B and class C switches on the London Midland & Scottish railway) and a headshunt length of 30 m this leads to the following overall diameters of the wye.

As can be seen a 5-way convoluted wye is considerably more compact.

Calculations report the radii whereas the overall size is the diameter.

read some lengths from corresponding Italian Wikipedia page which is much longer and presumed to be an overall length.

Add unit scale (-250 to +250) to the diagrams.

Heading - Asymmetric convoluted wye

In practice the convoluted wye may be laid out alongside a running track or station such as at Carbonia, Mals or San Candido, so one side is flattened with one of the headshunts either crossing the flattened side (Carbonia) or kept inside the bounding area (Mals & San Candido).

Figure out size calculations for this and do more diagrams.

Heading - Operation of a convoluted wye

The arrows on the diagrams illustrate the engine taking the left fork at each switch. This rotates the vehicle anti-clockwise. Taking the right fork will rotate the vehicle clockwise. The direction of rotation doesn't matter unless several (up to 4) engines are being turned simultaneously, in which case all must follow the same path and turn in the same direction. To turn several, each engine is advanced as a headshunt becomes free. A signalling and control protocol is needed to avoid collisions. Turning just one engine can use the one-engine-in-steam principle.

Use sharper curves and a longer headshunt to produce an easier to recognise animation. Don't try to make it to scale.

Grade (slope)
Clearer statement.

Verify arithmetic. %ge & ratio relate the same values but inverted. Tangent is opposite / adjacent, so unit one / ratio distance, or %ge as a fraction (*100) / unit one. Apply these to check angles (via atan) and check reverse function.

Ratio and per-mille are complements, so ratio number = 1000 / per-mille and per-mille = 1000 / ratio number

Tangent is unit 1 / ratio distance, so angle = rad2deg( atan( 1 / ratio distance))

or

tangent is per-mille / 1000 so angle = rad2deg( atan( per-mille / 1000 ))

ratio distance is 1 / tan( angle)

Bret Harte parodies
Title - Works of parody

Parodies and links to their targets

The Charles Reade parody Handsome is as Handsome Does refers to a Raby Hall and a Baron Raby. The Charles Reade story Put Yourself in His Place refers to a Squire Raby. There is also a Henry Little and Faraday Huxley Little in the parody and a Henry Little in Put Yourself in His Place. However, the plots of the two stories are different. Don't know about a style match. Characters called Dodd occur in Handsome is as Handsome Does as well as in the Reade novel Love Me Little, Love Me Long although there is no plot match.

Charles Henry Webb was a contemporaneous author of parodies, including a parody of Charles Reade's Griffith Gaunt and was an acquaintance of Harte.

For Lothaw, searching locates Gil Blas (unlikely), The History of the Human Heart: Or, The Adventures of a Young Gentleman (J. Freeman, 1749), The Story of Jack Ballister's Fortunes by Howard Pyle, which may fit The Hoodlum Band better.

See Les Misérables by Victor Hugo of which the first part is Fantine.

Harte's short story collections Condensed Novels (1867) and Condensed Novels: Second Series New Burlesques (1902) are parodies of contemporaneous writers and novels.
