My task is to integrate the Nest Cam with a python code. When nest Cam detects a motion , it should then take a picture and send it to my python code for further processing. How this task can be achieved ?
Nest has provided a sample means of Authenticating with the API for python at
https://developers.nest.com/documentation/cloud/sample-code-auth
You can then poll the Camera using the API for a change to the last_event object
https://developers.nest.com/documentation/cloud/api-overview#last_event-cam
and if it has changed, you can request the snapshot web_url and download the picture.
There are limits of 2 snapshots per minute if you do not have Nest Aware and 10 snapshops per minute if you do have Nest Aware. There are some other polling limits so you will want to read the API docs to ensure you don't go over them.

i want to build a website using node.js that will keep eye on change in data of API and it will send email if change is detected.
how to query on API every 10 min and detect for changes?
setInterval works only when the client is open. my advice to you is node-cron
that you use the package.
I am trying to use Logic apps to ping our website every 10 minutes. I would like to know how to get a response time of that call to make sure the website is now slow.
Currently i am doing this
Recurrence (Every 10 minutes)
Get Current Time
Http GET Call
Get Current time 2
Difference of (Current time 2 - Current time)
Condition to see if it is greater than threshold.
This looks like a not clean solution. Wondering if there is a easier way to get the time / latency of that HTTP call in step 3
According to the official doc, with the connector you're using is not possible to get response time. You'd better use Azure Functions for that. More info:

You can use azure application insights for this kind of situation it's the best and optimal solution.

I am totally new to Lambda (or AWS) and am still to build knowledge and experience around it.
Now, I was building an app where in it requires to fetch data from twitter Hashtag.
If I got it correctly, Twitter restricts number of API calls we make every minute(?) hence we need to have a backend and needs to have oAuth2 authentication.
In a simple express app, I would have done an API call in the global scope to get the data and use setInterval to hit that API after every x minute so as to not exceed number of limits.
Now based on the very vague understanding, I guess Lambda runs function when we need it, Hence is it right to assume that we can't use lambda for such use cases?
The old-school way of doing this is to run a cron job that fires a particular script every so often. The AWS way of running code periodically is using CloudWatch scheduled events. You can configure how often you want to run a given target, and set the target as a lambda function.

I have been using the asynchronous abilities of Node.js from quite some time now. But I am stuck on an interesting problem. Basically I have 2 API's that I need to call one after the other. Due to the asynchronous nature of Node.js I cannot retrieve the response of the first API request till it has finished and the respective callback function is called.
What I want to do is that I want to pass the response from the first API as request payload to the second API on the fly and not wait till the first API gets fully completed.
As a possible alternative, should I switch from building rest API to stream APIs?
Any pointers on how to do this?
Thanks
Yes, converting REST API'S to stream API is a better option. Node.js is known for its asynchronous behaviour. Because of the same all REST api's function in the same manner as you described earlier. As someone has previously pointed you could look at the Twitter Stream API for reference.

I have a system where various rss feeds are added. I want to follow the content and be notified when new content is added in the feeds without having to check them one by one.
I found out there is a pubsubhubbub protocol and that publishers can use various hubs which implement this protocol in their feeds. This is how I found out about superfeedr and I'm trying to work with their XMPP API. I installed their nodejs library and made a few subscribe tests that worked fine.
Is it possible to use the node superfeedr module to subscribe to a feed that doesn't use superfeedr? For example I found one that has:
link rel='hub' href='http://pubsubhubbub.appspot.com/'
Do I have to handle each hub separately or I can just send them the same requests based on the protocol?
Alex, I created Superfeedr.
Yes, of course it is possible to subscribe to a feed that doesn't use Superfeedr. Superfeedr acts as a default hub. You can add any feed, and you should get notifications for it. The only difference is that you may see delays. We poll feeds every 15 minutes, so, unless there are strong caches, you should see messages no later than 15 minutes after they've been published.
2 and 3 are probably not relevant given 1. However, I believe there are a couple other PubSubHubbub libraries, but they all require that your endpoint is outside the firewall... and all of them will only work for feeds that use the pubsubhubbub protocol. Even though your application will use each hub separately, the code should be the same, so that's transparent for you.
I hope this helps.
