How can I watch multiple files/socket to become readable/writable in Haskell? -

how watch several files/sockets haskell , wait become readable/writable?

is there select/epoll/... in haskell? or forced spawn 1 thread per file/socket , use blocking resource within thread?

the question wrong: aren't forced spawn 1 thread per file/socket , use blocking calls, get spawn 1 thread per file/socket , use blocking calls. cleanest solution (in language); reason avoid in other languages it's bit inefficient there. ghc's threads cheap enough, however, not inefficient in haskell. (additionally, behind scenes, ghc's io manager uses epoll-alike wake threads appropriate.)

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
