the following code gist on feedzirra updated content rss feed: feed = feedzirra::feed.fetch_and_parse(feed_url) feed = feedzirra::feed.update(feed) do_something_with_new_feed(feed.new_entries) if feed.updated? i don't understand how feedzirra know feed has been updated. can't working. in order know, have pass feed object returned (minutes or hours ago) feedzirra::feed.fetch_and_parse(feed_url) feedzirra::feed.update , no? how know if has been updated if use feed had fetch_and_parse? feeds (the sites accessing) can, don't necessarily, maintain 1 or 2 fields determine whether have changed since last access. these etag , last modified. if site supports either or both of these, returned when access feed. model should maintain these fields each feed of interest. feedzirra::feed.update uses them determine whether or not feed has been updated since last access. these allow feedzirra::feed.update pull entries new or changed since last access. if have neit

given snake , ladder game, write function returns minimum number of jumps take top or destination position. can assume die throws results in favor of you ** here solution, not sure it's correct or not. this problem similar frog jump in array.but before have model problem in format. create array of size 100 , each position store 6 if there no snake or ladder. store jump count . if ladder present @ point . if snake present store -ve jump @ location. now have solve in how many minimum steps can reach till end. main problem can solved using dynamic programing in o(n^2) time complexity , o(n ) space. have @ this blog post, full mathematical analysis of chutes , ladders, using both monte-carlo simulations , markov chains. show way of calculating minimum number of steps win (basically construct transition matrix , see how many times have multiply starting vector solution has non-zero final position). not efficient way of doing it, post wo

there's question 1 she's 4 years old , question kind of "time related" . i need implement logic prolog , call clr based application (mainly c# windows , mono , scala windows) take advantage of prolog features. problem is, can't found maintained "prolog.net" compiler... prolog.net looks 2 years old. p# looks 9 years old the other prolog.net looks 3 years old so have still maintained prolog compiler ? or, experience, think 1 of 1 above enough stable , enough secure use them without support ? this one, c# prolog, looks in development (latest release tagged june 2013). whether it's or not (or better other ones), i've got no idea. http://sourceforge.net/projects/cs-prolog/ also, amzi prolog has binding .net: http://www.amzi.com/manuals/amzi/ls/lsadotnet.htm and here's clr binding integrate swi-prolog .net world: http://www.lesta.de/prolog/swiplcs/generated/index.aspx

so question simple (i hope). have class constructor looks this: constructor(string szname) the string holding name; may more 1 part. john, john smith, john h smith, must valid inputs. know following: std::string input; getline(cin, input); myclass foo(input); and work fine. there anyway me directly send getline input constructor? thank in advance. well, if you're fine making function, this: std::string readline() { std::string input; getline(cin, input); return input; } and initialize class so: myclass foo(readline());
