AI Thread Summary
The discussion centers around a user's struggle with understanding a question related to even-parity SECDED encoding and error correction. The user expresses frustration over inadequate explanations from their tutor, leading to confusion when attempting similar problems. They seek clarification on whether their tutor's approach was correct and request assistance with a specific question involving error detection and correction of a hexadecimal value. A response suggests that the tutor's explanation is acceptable and encourages the user to break down the hexadecimal value into a table for better understanding. The focus remains on improving comprehension of error correction techniques in coding.

Hey guys it feels like I'm banging my head against the wall when it comes to these types of questions. My tutor helped me out with a question but he didn't explain it to well he just wrote all he was doing down and expected me to know every single thing. I had to go through textbooks galore to understand half of it and I don't even know if we got it right in the end, needed tons of help. Now when i look at a similar question all I see is further confusion. Can someone help me out with this question and tell me if they think the one my tutor helped me with was right. I am sure after 2 examples ill be able to get my bearings. Cheers!

Question: An even-parity SECDED encoded character has been retrieved, with hexadecimal value View attachment 4304. Was there an error? If there was an error correct it (reporting corrected ASCII character) or explain why it couldn’t be corrected.This is the one my tutor "helped" me with:

Hi RobJob! Welcome to MHB! :)

The explanation of your tutor seems fine to me.
Where are you stuck?
Perhaps you can start by splitting BEB16 into the same table?
 
Thread 'Is this public key encryption?'

Thread 'Is this public key encryption?'

I've tried to intuit public key encryption but never quite managed. But this seems to wrap it up in a bow. This seems to be a very elegant way of transmitting a message publicly that only the sender and receiver can decipher. Is this how PKE works? No, it cant be. In the above case, the requester knows the target's "secret" key - because they have his ID, and therefore knows his birthdate.

Thread 'Who is responsible for the software when AI takes over programming?'

I tried a web search "the loss of programming ", and found an article saying that all aspects of writing, developing, and testing software programs will one day all be handled through artificial intelligence. One must wonder then, who is responsible. WHO is responsible for any problems, bugs, deficiencies, or whatever malfunctions which the programs make their users endure? Things may work wrong however the "wrong" happens. AI needs to fix the problems for the users. Any way to...
