It is possible to get the user watch time of a live streaming? Eventualy clients ask me if we can know how much time each user watched the live.

I don't know if my idea is possible to solve with MS Access. The requirement:
I have one centralized DATA-database and several Client-Databases. It will be used to maintain a rescue team in our company. Each one has to press a button in his client and in the reception client is visible who is available in case of an emergency.
It even shows who is in which corner of the building the rescue person is.
Now, it's in human nature that in evening People forget to logout. Plan is to define a usual end of work time. The reception client verifies every 5 Minute if someone reaches his end of work time and can set him as out of office.
Problem is, perhaps Mr. X works today not until 17h as usuall - today he is available until 20h.
So, a message should Pop up 15 Min before his end-of work and ask him if he goes by time or not. If he answers to work longer, a flag should remove him from this function today.
Solution is almost 70% developped. Problem is now the little point, how to pop-up the message to the right user. One Idea is to check a message table if there is a message for him.
But, i don't like to make to much LAN traffic... if each client ask every 5 minutes the DATA DB if there is a message for him.
Has some one an idea?
Best regards

Polling a single table every 5 minutes should generate virtually no load. I've used a similar solution that polls every minute without any trouble on a networked database with ~20 users.
You can, of course, pull in these messages once, since they will fire at a set time, and then just raise them at that time.
You can just have a hidden form that's bound to a specific table, uses a filter on the username, and requery every x seconds, tests if there's a message ready, and then displays it.
Alternatively, you can pull in messages once, and have a hidden form that checks on timer if it's time to raise that message.
I'm working on a Rails 3.2 application where users create, read and update multiple kinds of reports. We use MySQL and Redis.
I would like to notify users when one of their reports hasn't been updated in the previous X months by showing them notifications on their profile/dashboard page in the browser.
I would prefer to do this asynchronously.
At some point, I would also like to have live, in-app notifications so users can be notified when a report they're watching has been updated or someone likes their report. Conceptually, I was contemplating the best way of going about doing this...
A cron job that runs a SQL query and retrieves all reports that have update_at fields older than 3 months, and creates a notification record linked to that user and report. A new notification record will be created only if user didn't have an existing notification.
A background job, using something like Resque that checks the database periodically throughout the day. Notifications are stored in a queue. This seems like it would scale better into a more robust, in-app notifications feature.
Are these my only two options? Is there a better asynchronous way to listen to the database, and notify a user when one of their records hasn't been updated in 3 months? Is some implementation of websockets necessary here?
I don't believe you necessarily need to use CPU cycles with some always-running background job, but that depends on how powerful you want these notifications to be. If you want them to be real-time, and you plan on using a publisher-subscriber model in the future then I'd consider a redis + node server setup.
The complexity of websockets means more implementation time. Will that extra time spent really benefit you? If it's very important that your notifications be asynchronous and real-time, like exchanging messages in a chat app or getting pop-up notifications on Facebook, then this is the right choice.
However, if all you really want to do is let users know when their reports are past a certain age, when they request their profile page, a cron that runs every couple of hours will be much easier to implement. You could even use Google Analytics to get a feel for when users are putting the heaviest burden on your app, and schedule the job around that.
First, create a rake task that completes the behavior your described above--check for old reports and create notifications. Put that in your app's lib/tasks directory. And then write a cron job like so:
$ 0 6,12,18 * * * cd /path/to/app && bundle exec rake task_name
This task will run 3x a day, at 6am, 12pm and 6pm.
From there, if you want to create an activity feed for your users, you could also implement a synchronous pub-sub solution pretty simply. E.g., User A subscribes to User B's reports, User B publishes a new report, after_save callback to create a notification for User A. This will be slower, it won't be live, but if it's a small app and this feature isn't a core part, then this makes better use of your time than the other options.
I have a problem related to automatic task scheduling.
Currently i am able to find out when my customer has last credited his account, how am i able to find out whether he will pay anything in the next 3 days?
So if no payment has been made in the next three days for any customer, to automatically alert me preferably by a notification directly to my ipad.
I dont want myself to open the app for checks to be done only when i log in, because then if i jump on my application 6 days later, i could have had a customer that hasnt paid in 6 days when the app should have alerted me on the 3rd day so i could ring my customer up to deal with the matter.
I need to work in this matter due to the structure of my application and business.
I am able to monitor everything else but need some insight on how I can go about doing this. the current notification system inside the phone only fires based on time, and I cannot do interval checks where maybe i could run a background task, if that would work then i would have done it like that but thats not the case.

If I understand your question correctly, you should compute the interval of the event that you want and post a wake-up timer that is that period of time from "now." If you need it through the notification center, then just handle it silently and clear it from the notifications.
Based on the discussion below:
You will need a little bit of server work. APNS looks complicated, but it really has very few moving parts -- especially if it is a private App. What system component is keeping an eye on Amazon? Do you have an App or web server? For example, if I were to poke a record into your system (purchased services) what workflow is triggered to notify Accounting to process an invoice and collections at a later date? Am I making any sense of your system architecture?
Perfect - you are done. You have all the system components you need and the rest is coding. The server app processes the accounts DB and finds new entries. If found, it publishes a record ID to the APNS server (Apple owns this server). You write code to register to receive the push-notification (subscriber). When you get a push, that will wake up your registered app with the record ID (and some other subscription stuff for bookkeeping -- but you are the only subscriber and only subscribing to one DB table -- so you can largely ignore. Now turn around and query based on that record. Done!
I need major help!!! I am designing a game that will be at a tradeshow which means lots of people walking by. The problem it seems is that once kinect sees you "New user" even if you are just strolling by it seems to kill or mess up the ONISkeletonEvent.USER_TRACKING data when that user is "LOST".
Please if you have any ideas I need them fast! This thing needs to ship end of week. I thought I could handle this by assigning an activeUserID and filtering based on that but it just doesn't care. When it "LOST USER" it is game over even if that was just someone watching and then moving away.
PLEASE HELP!!!
OpenNI identifies each user with a unique ID. Each event message comes with a user id which connects the message to a particular user.
Once a user has its skeleton calibrated, you can skip further calibrations for other users, thus limiting the skeleton tracking to the first user who completed the skeleton calibration procedure.
I'm making a program that has a function that can only be run at a certain time. I want to make ti so people can't just change the clock time on their computer to make it work. Is there a place I can ping online that will return the exact time?
Also, because I don't want them to be able to cheat with time zones, but I want to incorporate them, is there a way to find out the time zone a host computer is in?
Thanks.
