Best way to authenticate boto3??
-
Hello All,
I'm building a Python based desktop application to work with some AWS services. The application has a front-end built with the kivy framework and AWS boto3 being the primary tool in the back-end. So my aim is to access services such as AWS IoT & DynamoDB using this application.
The question is, according to AWS standards, we've three modes of authentication for boto3 to access AWS servers.
1. X.509 certificates
2. IAM Authentication
3. Cognito IdentitiesX.509 certificates are mostly preferred for embedded devices and not in applications.
That leaves me with 2 options, either IAM or Cognito.
I'm not convinced with the idea of hard coding credentials into our code.
In such a case which one of these is a better way of authentication and why?
Do we really have a problem if we hard-code IAM credentials in our application code?

Hi team,
Any one have experience in Altium schematic designing.
I am facing some issue in Hierarchy->harness in Schematic.
The offpage number for harness is not showing, and while generation the smart PDF if we click the harness port /green box the page want to go there automatically, but that also not working. -
Hi @dipu_varghese ,
Here is the sample input from the binary edge impulse inference,
Predictions (DSP: 16 ms., Classification: 1 ms., Anomaly: 2 ms.): idle: 0.91016 snake: 0.08203 updown: 0.00391 wave: 0.00391 anomaly score: -0.067”And from here for example we can try to get the updown values only by attaching the device to another controller and read the Serial string directly.
void setup() { // Start serial communication at 9600 baud Serial.begin(9600); } void loop() { // Wait until there is data available on the serial port while (!Serial.available()) { // Do nothing } // Read the input string from the serial port String inputString = Serial.readStringUntil('\n'); // Find the position of the "updown" value in the input string int updownPos = inputString.indexOf("updown:"); // If the "updown" value was found in the input string if (updownPos >= 0) { // Extract the "updown" value from the input string String updownString = inputString.substring(updownPos + 8, inputString.indexOf('\n', updownPos)); // Convert the "updown" value to a float float updownValue = updownString.toFloat(); // Output the "updown" value Serial.println(updownValue); } }The sketch should then output the "updown" value, which is 0.08203.
Hope this will be helpful, let me know if you need more clarification.
