clojure - On the 4Clojure website, how do you see your previous problems, so you can return to one of them? -

i'm doing problems @ 4clojure. how, when finished problem (around #22), link appeared jumped me problem #35. want problems skipped. when i'm logged in 4clojure, website shows me problems after last 1 completed, #34. is there way see problems (completed , uncompleted) @ 4clojure, can skipped ones? the headers on problem list page clickable change sort order. default sort order "sort first on whether you've solved it, , on how many other people have solved it", problems you've solved drift bottom (which on page 2). can click heading sort differently: example, click on solved heading see problems you've solved first. or, of course, can edit url, since urls predictable: http://www.4clojure.com/problem/22 problem #22.

scala - Why does immutable.ParMap.mapValues return ParMap instead of immutable.ParMap? -

in scala 2.11.6 application have defined immutable.parmap so: object foos { val foos: immutable.parmap[string, foo] = immutable.parmap( ... ) } later on, i'd create new immutable.parmap using same keys, use mapvalues : val fooservices: immutable.parmap[string, fooservice] = exchanges.exchanges mapvalues (_.fooservice) scala complains expression of type parmap[string, fooservice] not conform expected type parmap[string, fooservice]. as workaround can use comprehension, compiler permits: val fooservices: immutable.parmap[string, fooservice] = ((name, ex) <- foos.foos) yield name -> foo.fooservice but nice able use library functions designed exact task. why can't mapvalues infer specific type here? it's not matter of inferring specific type. it's instance of scala.collection.parallel.parmaplike$$anon$2 , view of underlying map (the created map forwards operations original). it have been created separately...
