What are the differences between edge computing and fog computing?

The update() method would be what I need, if it returned its result instead of modifying a dictionary in-place.
>>> x = {'a': 1, 'b': 2}
>>> y = {'b': 10, 'c': 11}
>>> z = x.update(y)
>>> print(z)
None
>>> x
{'a': 1, 'b': 10, 'c': 11}
How can I get that final merged dictionary in z, not x?
(To be extra-clear, the last-one-wins conflict-handling of dict.update() is what I'm looking for as well.) less

Recently, I tried to upload a few of the sample sketches onto it, such as the Blink one. However, none of my attempts are working and they result in the same error every time I try it - avrdude: stk500_recv(): programmer is not responding.
I have enabled '/dev/ttyUSB0' under Tools -> Serial Port. I have also selected the correct board (Duemilanove with Atmega 328) from the list. Yet, I am not able to resolve the issue. I have searched online as well and none of the other responses for this problem seem to be working for me. Could someone tell me why I am encountering this issue and help me resolve it?
Update: I tried turning the onboard Atmega and fitting it in the other direction. Now, I encounter no problems uploading, but nothing happens afterwards. The onboard LED also does not seem to be blinking. less

However I came across this single line in a Computer Science textbook (A Level Computer Science for AQA Unit 2, Kevin R Bond 2016, pg265)
The Raspberry Pi computer is based on the Harvard architecture
Having searched online, I can't find any solid sources that either prove or disprove this statement. Is this in error? I would appreciate a source given in an answer.
(I'm aware the Raspberry Pi SE exists, but given the fact that the tag does not exist there, I thought it more appropriate to post it here) less
I'm working on some IoT integrations and I am wondering where in the Azure I can parse my IoT data (JSON data).
My earlier workflow was this; sensor pushes data -> iot hub -> stream analytics jobs -> sql database. Stream analytics job works fine but I have heard that it is not "right" way to parse data in Azure. So what is the right and best way to do that. I need to save it to SQL database.

But instead of storing these waypoints in a standard preprogrammed array, the user will need to be able to add, remove waypoints and move them around. Unfortunately the Arduino does not offer a vector type as a built-in library.
I am currently contemplating two options:
In Container for objects like C++ 'vector'?, someone posted a general purpose library. It does not contain any index deletion, or movement operations. But it does contain some memory management strategies.
I have used malloc, dealloc, calloc in the past. But I do not like that option at all, especially with classes. But is this a better option in my senario?
