a signal process has sent within signal handler not delivered 20 seconds , delivered. what probable causes? i know probable reasons in general. the actual code looking @ here most probably, you're calling function within signal handler mustn't call within signal handler. see man 7 signal details: async-signal-safe functions a signal handler function must careful, since processing elsewhere may interrupted @ arbitrary point in execution of program. posix has concept of "safe function". if signal interrupts execution of unsafe function, , handler calls unsafe function, behavior of program undefined.

how might 1 go constructing linked list in python. realize python not low level. suppose have large object, , want contain reference large object in instances of class: class largeobject: def __init__(self): # use lots of memory class smallobject: def __init__(self, large_object_ref): self.large_object_ref = large_object_ref # ... largeobj = largeobject() smallobj = smallobject(largeobj) # happens in memory? i want ensure self.large_object_ref never becomes deep copied instance of largeobject in memory, how prevent this/ensure this? i admit know little python's memory model or management, 1 isn't supposed have in python. familiar c/++ though borrowing terms , ideas area. python pass-by-assignment equal pass-by-reference mutable objects (and of user-created objects mutable).

i creating reddit-type app. have array of stories, , each story has title, description, , votecount. want have separate .write rules votecount, structured rules - "stories": { "$story_id": { "title": { ".write": "auth !== null" }, "description" { ".write": "auth !== null" }, "votecount": { ".write": "newdata.val() === data.val() + 1" }, } } this works existing stories.however, no longer allows me add new story, unless add .write rule directly $story_id node. , of course stops me having special .write rule votecount node. any ideas on why happens? so users have .write access on higher level, can write data follow specific rules? you'll want put in .validation rule, instead of .write rule. a simple way remember .write rules determine who can write data, while .validate rules determine what data can written.
