Update - Meeting Summary:

Agenda: Sensor Selection and Connectivity option
Time & Date : 10.15 PM to 11.20 PM (23/Sep/2019)
Attendees: Swalah, Akash, Rafi, Alex and Salman

We started the discussion from what we have done so far, and we know that we were stuck at sensor and connectivity selection.

Cellular over LoRa WAN: LoRa WAN is not a good option since we need to set up the complete infrastructure from scratch. Also currently we are only planning to deploy 10 test nodes, it will not be worth setting it up just for that. On the other side, Cellular is already an established network which is feasible to manage 10 devices and can be implemented rapidly. Thus we are planning to go with cellular in the first batch. (Please share your feedback too, it's very important).

Sensor parameters: After got into a conclusion on the connectivity, we started discussing the sensor parameters to be collected for the analysis and prediction. They are :
-> Water level (High Priority )
-> Water Quality
-> River Flowmeter
-> Rain Gauge

Since we only got a few sensors details in past weeks, we decided to list them again based on the parameters and priority. We distributed them based on attendees interest.

ToDo:
-> All members are requested to submit sensor details before the next meeting which is scheduled for 7th December 2019 (High Priority)
-> Documentation: If possible add our Mission and Vision to our GitHub page

NB: Next team meeting will be on 7th December 2019 from 09.00 PM to 10:00 PM

Hello @Abhay,

There are numerous ways to persist data generated from IoT devices in the cloud.

Since you haven't mentioned any specific requirements, I'm just giving you some general options commonly used.

Normally you have to write a service running on cloud to accept data from your IoT device and persist it on any persistent storage methods such as RDBMS or NoSQL Database engines or even plain files. You can write REST, Socket (Websocket / Socket.io or MQTT services for this. If you have to submit data in high frequency to the server from numerous devices the same time, you may better to consider using some load balancers and use lazy write or in-memory database like Redis or Casandra.

If you don't like to write the entire server service your self, you can use IoT cloud with built-in APIs or with simply configurable API generators.
You can also use Firebase like solutions for faster setup with cloud functions.

Also, take a look into this article published in DZone and don't forget to read its comments, they contain some more info from others.

Proud of you @salmanfaris

This month we are discussing Psychology and Perils of Polyglot/Mixed Language Programming

by Praseed Pai

Author of .Net Design Patterns and
C++ Reactive Programming,
Father of SLANG Compiler.

Nowadays, every developer in the world ought to be a Polyglot (Programmer) to do something worthwhile in the industry. But, most are not prepared to get into that groove. The Session will give necessary conceptual, ontological, linguistic and formal background to navigate between programming languages with ease. The Session has got examples in C++, C#, Java, Scala, Python, JS, Python/C interface, Java Native Interface, P/Invoke, COM interop, RxJava/RxJS./Rxcpp/Rx.net etc. All code snippets are taken from real-life projects which the presenter has been part of, in the past two decades. The session also covers some pitfalls which an aspiring Polyglot Programmer should be watchful, as well.

Don't miss it, book your seats today. It's a golden opportunity for all Enthusiasts to listen from the true industry experts!

Come and join​ us! Have a Java Coffee

Date & Time : 29th February 2020 02:30 PM to 05:30 PM

Thanks for sharing @salmanfaris

@sivanath

Oh okay.

Please bring your device if you're coming for the upcoming MakerChat 0x13 tomorrow (IST). Either I and @salmanfaris or both of us will be there.

Or else we can set up a call sometime this weekend or the next week and sort it out.

Let me know.
