cycle

I would like to create a graph that loop n times before going to sink. I've just created this sample that fulfill my requirements but doesn't end after going to sink and I really don't understand why. Can someone enlighten me? Thanks. import akka.actor.ActorSystem import akka.stream.scaladsl._ import akka.stream.{ActorMaterializer, UniformFanOutShape} import scala.concurrent.Future object test { def main(args: Array[String]) { val ignore: Sink[Any, Future[Unit]] = Sink.ignore val closed: RunnableGraph[Future[Unit]] = FlowGraph.closed(ignore) { implicit b => sink => { import FlowGraph.Implicits

Well, I was using itertools.cycle().next() method with Python 2.6.6, but now that I updated to 3.2 I noticed that itertools.cycle() object has no method next() . I used it to cycle a string in the spin() method of a Spinner class. So if we cycle the tuple ('|', '/', '-', '\\', '|', '/', '-') , it'll print: | , / , - , \ , | , / , - , | , / and so on... I've searched the release notes of Python 3.0, 3.1 and 3.2 and didn't noticed any change on this. When this have changed? Is there any simple alternative to achieve the same functionality as before? Thank you in advance. d0ugal iter.next() was

I had a look at question already which talk about algorithm to find loop in a linked list. I have read Floyd's cycle-finding algorithm solution, mentioned at lot of places that we have to take two pointers. One pointer( slower/tortoise ) is increased by one and other pointer( faster/hare ) is increased by 2. When they are equal we find the loop and if faster pointer reaches null there is no loop in the linked list. Now my question is why we increase faster pointer by 2. Why not something else? Increasing by 2 is necessary or we can increase it by X to get the result. Is it necessary that we

http://www.lunatestsite.co.uk/products/lifestation Cannot for the life of me fix this. Only in IE8 so far. I had the same issue on the homepage cycle, but managed to fix by declaring width, height and background: none !important on the img's in question. I thought it might be a png issue, but the same happens with jpgs: http://www.lunatestsite.co.uk/test-disappearing-jpgs Same result: often a flicker of the first of the two images in the slideshow, then disappears. Any ideas at all appreciated. SOLVED: My original fix worked for this in the end too : adding the background: none important!, and

i cannot understand a certain part of the paper published by Donald Johnson about finding cycles (Circuits) in a graph. More specific i cannot understand what is the matrix Ak which is mentioned in the following line of the pseudo code : Ak:=adjacency structure of strong component K with least vertex in subgraph of G induced by {s,s+1,....n}; to make things worse some lines after is mentins " for i in Vk do " without declaring what the Vk is... As far i have understand we have the following: 1) in general, a strong component is a sub-graph of a graph, in which for every node of this sub-graph

In Perl, there is an ability to break an outer cycle like this: AAA: for my $stuff (@otherstuff) { for my $foo (@bar) { last AAA if (somethingbad()); } } (syntax may be wrong), which uses a loop label to break the outer loop from inside the inner loop. Is there anything similar in Ruby? Jörg W Mittag What you want is non-local control-flow, which Ruby has several options for doing: Continuations, Exceptions, and throw / catch Continuations Pros: Continuations are the standard mechanism for non-local control-flow. In fact, you can build any non-local control-flow (subroutines, procedures,
