ocaml - Map a subset of a polymorphic variant - i want apply function values within variant, result of function has same type input. how can create types work out? here's current attempt: module t : sig type generic = [ `foo of int | `bar of int ] val map : (int -> int) -> ([< generic] 'a) -> 'a (* val : [`foo of int] *) end = struct type generic = [ `foo of int | `bar of int ] allow map fn = function | `foo x -> `foo (fn x) | `bar x -> `bar (fn x) allow map : (int -> int) -> ([< generic] 'a) -> 'a = obj.magic map (* allow : [`foo of int] = `foo 1 |> map succ allow b : [`bar of int] = `bar 1 |> map succ *) end this works as-is, if uncomment let a line get: values not match: val map : (int -> int) -> [ `foo of int ] -> [ `foo of int ] not included in val map : (int -> int) -> ([< generic ] 'a) -> 'a it seems defining a ...

gdi+ - How do applications like Firefox calculate text height efficiently? - i'm curious technique fast applications (maybe safari improve illustration here) calculate height of terribly long page of text (for example, chat log or huge document). considering there huge amount of text same line height, can multiplied number of lines. however, how know how many lines <p> span in specific width? what can come they: calculate width of every character , store quick addition, use calculate width of words, add words , spaces' widths while comparing block-level width, adding lines needed. this seems indeed fast, since additions , comparisons way, way faster measuring string in gdi+. have no thought if done, since reliability comes first, , afaik text rendering introduces kerning, , have no thought how easy or hard info gdi+. also, a screenshot reactos made me believe firefox calculates each letter's size , position. text gdi+ measurement kerning
