You can use ajax on the concerned web page to call a web service at set intervals (say 3 seconds) which returns whether any new entry has been made.

The Google Classroom documentation says:
A StudentSubmission resource is implicitly created for each student when a new question or assignment is created.
When I create an assignment in the class stream, and a student joins the class after this, they see the assginment as 'Not done' in their stream, and the teacher sees an extra 'Not done'. However, it seems the student can not submit the work via the API (because there is no StudentSubmission record when I query the API, cfr. documentation?). Is this expected?
Can I create a StudentSubmission manually after the coursework was posted?
After further looking into this, it seems there was a student submission in the NEW state. I was under the impression that these could not be used for submitting answers, but it seems they can.

When running UserMailer.new.perform, my mailer is sent and I get an email almost right away, but when I use UserMailer.perform_async, it spits back an object number and I never receive an email.
Can someone please tell me why this is happening and what the difference between these two methods are?

I am debugging a boost asio unix domain protocol client, after i issue async_receive , the completion handler gets called infinitely with 0 bytes_transferred, there are no errors passed to the completion handler. the error code is success.
Finally i got the problem nailed , i am posting the answer here , just incase some body else might very likely run into the same problem.
The completion handler falls into infinite loop if the boost::asio::buffer passed to the async_receive function is of length 0. In my case i was passing a vector of size 0.

I would like to have the data in my site individually. For example: visitant 1 visited page 1, page 2, page 3, at time x,y,z.
How can i get this data in analytics?
You cannot see data for individual visitors in GA (and trying to do so would violate Googles Terms of Service).
You can redirect the tracking calls to your own server and write a script to parse for visitor data, see me answer here:
What would database-schema/database-design look like for google analytics?
(Those methods served for compatibility with the Urchin analytics software - since support for Urchin was dropped it might be that those method will be dropped at some point in the future).

I need to screenscrape a bunch of pages and store them in a database using ActiveRecord. I messed around using EventMachine and Typhoeus but I get flaky results, mostly mysteriously empty records getting saved.
What's the trick? I had the best results with scraping pages and writing them to disk, then inserting them into the DB, but I'd really like to do it in a single pass.
Is anybody doing this successfully?
My guess is your threads are sharing an AR connection. This will cause problems, and anyway concurrency won't get records into your database any faster. I suggest you download concurrently and insert them in a single thread (like you've been doing.)
