I aim to implement multiple node streaming, and concurrently modify the value of a key. I would like to perform this task using C++ on an Arduino platform. Could you kindly assist me in accomplishing this task?
i tried this to read node in arduino and i am able to do multiple node stream but sometimes node listening happens immediately and some times it takes time

I have a small project I am trying to wrap my head around. I already have the UI and the database built and working.
The app should ping a list of IP addresses every x seconds, and then update the UI if the address is up or down. What is the best way to go about executing this and updating my ui?
I would recommend two approaches.
Using JavaScript and AJAX: You can periodically execute a client side function to call a server side function to ping the list of IPs and update the UI.
Using Signal R: This is a framework suitable for real time web apps. So in your case it does make sense.

I want to run load & performance tests and monitor them via Grafana. I have the JMeter Dashboard and JenkinsCI Dahsboard setup and running, so I can see the client side data in real time. This is a good setup.
What's next, is trying to combine the Server Side Data concurrently with the Client Side data at the same time, within the same dashboard. I have a LogicMonitor installation for the Cloud Instances on AWS.
Does anyone know how to do this?
Suggestions?
As it turns out, you cannot do this. Logic Monitor Does not use InnoDB for format, so, it's not an easy port over to the data.

I would like to set individual timer for each parse (Parse.com) object so that the objects will disappear in a while. I am currently programming an iOS app. I will be appreciate that u guys can give specific answers.
I would read up on cloud code, and once you do, create a function that goes through your objects and deletes some based on your given parameters. On parse.com, you can schedule this function to run in intervals.

I have to create distributed publish subscribe system, but I'm stuck at the very begining beacuse I can't figure out how to exchange messages between processes on different nodes. Any ideas?
Sending a message to a process on another node is the same as inside local node. The problem is only to determine its pid. This can be made by introducing a registar which maps some known data to pids. The registrar may be a process with well known name or address storing those mappings inside, a bunch of processes to spread load or a database.
For a start you can try distributed gproc.

I have a 3.5mm to IR sensor to connect to my headphone jack. I want to know if there's a way to create a basic app for my TV that will control it's Volume, Power On/Off, input, and number pad. I've kept researching for about a week now on how to do this, but haven't found an answer. Can someone help me?
Yes is it possible, you only need an application what play wav files.
Or jsut a file browser.
But you can find a plenty of applications and tutorials and details all over the internet.
