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?

The discussion includes how exactly an interpreted language works on a Microcontroller?! Besides that, we have covered the pros and cons and when it is preferred to use Python on Microcontrollers when 95% of existing embedded code is written using either C or C++. Listen now and let us know your feedback and opinion!
Stay tuned till we meet with another exciting topic on next week!

Hi all,
I recently came across this post where they have shown photos printed on PCB in high resolution. I would like to know how to add this kind of photos to the silkscreen layers of the PCB in Eagle/Altium.
Adding such kind of photos will be attractive for beginners and also can be used for educational purposes too.
Please let me know in case anybody knows. -

@abdultechguy999 usually https://dl.espressif.com/dl/package_esp32_index.json this works while installing through boards manager. But I faced the same issue some times. it might be due to a couple of reasons.
Bad Internet connectivity
The license of the https://dl.espressif.com/dl/package_esp32_index.json might be expired(If this is the reason you can't do anything but just wait until they re-activate the license)
I remember there is a way to install the board files offline by downloading from some github repos.
All the best.
