message-passing

I,am developing an extension in which i have to extract data from linkedin profile page when user press button on popup. I,am passing message from the popup.js page to contentscript and in response i will get data extracted from linkedin profile page by contentscript so that i can display it in popup.html. But I,am getting error when i inspected the popup.html. The error is: Port: Could not establish connection. Receiving end does not exist. lastError:29 Error in event handler for 'undefined': Cannot read property 'farewell' of undefined TypeError: Cannot read property 'farewell' of undefined

I initially asked this question here , but I've realized that my question is not about a while-true loop. What I want to know is, what's the proper way to do high-performance asynchronous message-passing in Java? What I'm trying to do... I have ~10,000 consumers, each consuming messages from their private queues. I have one thread that's producing messages one by one and putting them in the correct consumer's queue. Each consumer loops indefinitely, checking for a message to appear in its queue and processing it. I believe the term is "single-producer/single-consumer", since there's one

Some background I'm working on building a programming language for digital media programming, which should support concurrency using no-sharing message passing and soft real-time (i.e. do your best to compute audio/video without losing samples or frames and with a constant throughput). It turns out that both these features are surprisingly difficult to combine, mainly because of one particular constraint: real-time code should not dynamically allocate memory. My language should make it easy to implement something like this: One thread computes audio samples based on parameters. These can be,

I've been looking into learning erlang, and as a result, have been reading (okay, skimming) about the actor model. From what I understand, the actor model is simply a set of functions (run within lightweight threads called "processes" in erlang), which communicate with each other only via message passing. This seems fairly trivial to implement in C++, or any other language: class BaseActor { std::queue<BaseMessage*> messages; CriticalSection messagecs; BaseMessage* Pop(); public: void Push(BaseMessage* message) { auto scopedlock = messagecs.AquireScopedLock(); messagecs.push(message); }

My overall goal was to take a screenshot via the background page using: http://developer.chrome.com/extensions/tabs.html#method-captureVisibleTab and pass it to the content script so I can use the page's HTML DOM to analyze the screenshot and cut it up the way I would like. However, I can't seem to pass the dataUrl back to the content script with Message Passing: http://developer.chrome.com/extensions/messaging.html I tried JSON.stringify() but to no avail. This works perfectly fine: background.js chrome.runtime.onMessage.addListener( function(request, sender, sendResponse) { sendResponse(

So let me explain: I basically want so when you post a comment, (i use a js/jquery script to send string to insert.php which inserts to the database) you will receive 2+ points. Now i have done so you get +2 points, BUT i want to display a message like stackoverflow. I already know how to display a message like stackoverflow, but in somehow i need to send from insert.php(after you inserted), this: <div id='message' onclick="closeNotice()" style="display: none;"> Hey, <b><? echo $pusername; ?></b> - You've just got +<? echo $gpm; ?> points for your comment! <a href="#" class="close-notify"
