Storm guarantees data processing by providing an at least once processing guarantee. The most common question asked about Storm is "Given that tuples can be replayed, how do you do things like counting on top of Storm? Won't you overcount?" Storm 0.7.0 introduces transactional topologies, which enable you to get exactly once messaging semantics for pretty much any computation. So you can do things like counting in a fully-accurate, scalable, and fault-tolerant way. Storm默认的reliable特性支持 at least once processing guarantee. 这个在某些场景下明显是不够的, 比如计数, 不断的replay必然导致计数不准, 那么需要支持 exactly once semantics.

I'd like to export one of my Processing sketches into gif form, and am using extrapixel's Gif-animation library ( http://extrapixel.github.io/gif-animation/ ) to do so. I am able to export the correct number of frames, but they all appear to be empty. Any ideas why this is happening? import gifAnimation.*; GifMaker gifExport; float angle = 0.1; void setup() { size(500, 500); smooth(); noStroke(); background(0); frameRate(12); gifExport = new GifMaker(this, "spin rect sine growth.gif"); gifExport.setRepeat(0); // make it an "endless" animation gifExport.setTransparent(255); // make white the

Of late, most of my programming experience has been in Processing , and more recently I have been wanting to branch out a little deeper in to some JavaScript, since they are slightly related. I was just wondering, as my recent searching has turned up nothing, if JavaScript had a similar function to Processing's "map" function, in which a value and it's range is taken and remapped to a new range? More info here: http://processing.org/reference/map_.html PS: Yes, I also know that www.processingjs.org exists, but I was just wondering if JS had such a function natively. The function below produces

　　最近老是换应用平台，将processing里的代码转移到eclipse中。 processing 关于转换成eclipse的介绍也可以使用，但是没有介绍具体怎么使用第三方库 Processing in Eclipse \ Processing.org 　　如果需要用到第三方库时，需要自己手动添加，坑来了。 插一脚：不一定按照这个方法走，还有个 proclipsing 插件，给出油管的地址： 064 - Supervisorio em Processing - A Classe PowerMeter e KNOB - Eclipse - YouTube 这个是文字描述过程： Proclipsing: Using the Eclipse IDE for Processing Projects: 14 Steps 很抱歉，由于谷歌停止维护下载网站了，所以只能通过以下.zip的方式读取 ybakos/proclipsing: Eclipse plugin for Processing, migrated from https://code.google.com/p/proclipsing. 还是很抱歉，安装插件的过程还是出现了问题 ， 如果说是我的eclipse 64 位不匹配的问题，我还要重新下载32位的安装，甚是麻烦。 决定还是选择一开始的第一种方式，导入包吧。 步骤： 1

Hi Im using java but Im trying to make a delay that doesn't stop the program but stops that block of code kind of for example if I have it in a method that adds 1 to a variable I want it to add 1 then wait one second then add 1 again but delay() stops the whole program and thread.sleep doesnt work in a processing project. You should not use delay() or Thread.sleep() in Processing unless you're already using your own threads. Don't use it on the default Processing thread (so don't use it in any of the Processing functions). Instead, use the frameCount variable or the millis() function to get

x-post Processing Forum I'm trying to make a super simple sketch where the user inputs a point with mousePressed, then (after a delay), processing plots a point at a random place on the screen back at you, and the points slowly fade into a semitransparent background. Here's my code, I've tried a bunch of different ideas but nothing seems to have worked, and now I'm at a point where nothing is working at all. Any pointers? void setup() { size(600, 600); background(0); stroke(color(168, 168, 168)); strokeWeight(2); frameRate(60); smooth(); } void draw() { if (mousePressed) { ellipse(mouseX
