Although notice that push_heap operates in logarithmic time." My question is what kind of data structure is used to mantain a priority queue with O(1) for push and pop ?

• What is the correct position of braces or does it not matter

  - by TheLearner

  I noticed in Objective C that xcode automatically uses a strange position of braces: if (statement) { } whereas I am used to using: if (statement) { } it just makes it easier to read. Is it a matter of preference or is a standard that should be followed when writing Objective C applications?

  I would like to list folders from a webserver into a treeview, keeping the hierarchy. It should not go under level 2 (so root - level 1 - level 2). Would this be possible somehow?

• Hibernate custom join clause on association

  - by myso

  I would like to associate 2 entities using hibernate annotations with a custom join clause. The clause is on the usual FK/PK equality, but also where the FK is null. In SQL this would be something like: join b on a.id = b.a_id or b.a_id is null From what I have read I should use the @WhereJoinTable annotation on the owner entity, but I'm puzzled about how I specify this condition...especially the first part of it - referring to the joining entity's id. Does anyone have an example?

• Facebook JS API: Is it possible streamPublish to many targets at once?

  - by Prody

  I'm trying to make my app publish to all my friend's walls. From what I read in the API docs, the streamPublish method only allows you to publish to one person at a time. What I'm doing is fetching all the friends with FB.Facebook.apiClient.friends_get then a for on the reuslts, and a streamPublish for every one. This however seems hacky. Is it possible to streamPublish to many targets at once?

  Consider something like: cat file | command > file Is this good practice? Could this overwrite the input file as the same time as we are reading it, or is it always read first in memory then piped to second command? Obviously I can use temp files as intermediary step, but I'm just wondering.. t=$(mktemp) cat file | command > ${t} && mv ${t} file
