broadcast

Are there any libraries which put a reliability layer on top of UDP broadcast ? I need to broadcast large amounts of data to a large number of machines as quickly as possible, and generally it seems like such a problem must have already been solved many times over, but I wasn't able to find anything except for the Spread toolkit, which has a somewhat viral license (you have to mention it in all materials advertising the end product, which I'm not sure our customer will be willing to do). I was already going to write such a thing myself (because it would be extremely fun to do!) but decided to

I would be glad for some input on the following implementation of a BroadcastCopyBlock in TPL Dataflow, which copies a received message to all consumers, that registered to the BroadcastCopyBlock and guarantees delivery to all consumers, which are linked to the block at the time it receives the message. (Unlike the BroadcastBlock which does not guarntee delivery of messages, if the next one comes in, before the former message has been delivered to all consumers). My main concern is the reserving of messages and releasing of reservations. What would happen, if a receiving block decides to not

I want to send data to the specified user, and no one else. currently to broadcast to everyone I do: socket.on('newChatMessage', function (message) { socket.broadcast.emit('newChatMessage_response', { data: message}); }); now what I want to do is simply something like: socket.on('newChatMessage', function (message) { socket.to(5).send('newChatMessage_response', { data: message}); }); to(5) would be the user with the ID of 5. I think the missing piece for you is inside this function: io.sockets.on('connection', function(socket) { ... }); - That function executes every time there is a connection

Let's say I have a Region Actor, and each region has a certain number of people inside it. How do you broadcast a message to everyone, knowing that the list of people can change over time, broadcast routers seems to be the choice, but then the problem is that they have a maximum number of routees, and that I cannot dynamically append people to a router. My question is: I know there is an EventBus, I could subscribe my people to the event Bus, but I dont want them to recieve every message posted, I want them to recieve the messages of the region. right now in akka, we have to create a router

I have this code, where master sends initial data to his slaves. It uses MPI_Bcast (broadcast) function but when the Broadcast is called, the master continues but the slaves are stuck in deadlock. Code snippets are following: Master { run() { ... MPI_Pack(&offset, 1, MPI_INT, buffer, BUFFERSIZE, &position, MPI_COMM_WORLD); MPI_Pack(&dataSize, 1, MPI_INT, buffer, BUFFERSIZE, &position, MPI_COMM_WORLD); MPI_Pack(dataLoader.getData(), dataSize*dataSize, MPI_CHAR, buffer, BUFFERSIZE, &position, MPI_COMM_WORLD); MPI_Bcast(buffer, position, MPI_PACKED, 0, MPI_COMM_WORLD); printf("master ok"); } }

I'm developing an accessibility service in xamarin.android. all is fine, but I want the broadcast receiver on the service. I know that I'll have to derive my accessibility service from broadcast receiver, but it's not possible because the service is already derived from Android.AccessibilityService. actually, the thing is that, when user does some configuration change on main activity, I want to raise an broadcast receiver for which, my accessibility service should listen. So, any ideas for this? Within your Service , define an BroadcastReceiver inner class and within your Service constructor

How can I turn the sceen on ? I tried something like this adb -d shell am broadcast -a android.intent.action.SCREEN_ON It really should work, I send broadcast intent it is received by the system, but the screen doesn't turn on I do not understand what is the problem, is it possible to turn the screen of the device by code ? I mean with software ? Cause it seems like the turning on of the screen is done just by the hardware button press . . . at least I got that felling , am I wrong ? Gallal I could be wrong about this, but... You shouldn't think of broadcasts as something to send to get things
