QUESTION
I sort of need help here, honestly not sure where I went wrong, here is the full code. I am sort of new, just trying to bring back the mention user and the reason back in a message instead of doing anything with this information.

ANSWER
Answered 2021-Jun-15 at 06:17You are violating the JPA spec by accessing the persistence context in a lifecycle listener.
See the JPA Specification 4.2 Section 3.5.2
In general, the lifecycle method of a portable application should not invoke EntityManager or query operations, access other entity instances, or modify relationships within the same persistence context. A lifecycle callback method may modify the non-relationship state of the entity on which it is invoked.
"a portable application should not" is the specification way of saying: Don't do that, anything might happen. Maybe the world ends.
The fix is not to do that. Maybe be preloading the currently logged in user and reference it so you may access it in your entity listener and do not set a reference to the user, but simple store its id or similar.

QUESTION
I was reading over a resource https://www.mi.mun.ca/users/cchaulk/misc/boolean.htm and I noticed the xnor
simplification seems to have mixed outputs.
15a
, 15b
, 15c
are all focusing on xnor
but only 15b
seems to be correct when I attempt to check.
For reference:
...ANSWER
Answered 2021-Jun-14 at 21:0415b is the definition of XNOR in conjunctive normal form. 15c is the negation of XNOR (i.e., XOR) in disjunctive normal form. You can derive this using De Morgan's laws, which state
'(XY) == 'X + 'Y
'(X + Y) == 'X'Y
Using these laws, we can first write 15b

QUESTION
I created a simple client and server using CPPRESTSDK
. The client sends an image and on the server, I save the incoming file and then start doing the processing phase afterwards.
Now I want to check if the sent file is actually an image file and not some other random file. For that, I check the first few bytes of the file and this allows me to know what I'm dealing with.
This is the snippet responsible for saving the file:
ANSWER
Answered 2021-Mar-07 at 02:45You need to open the file stream for both reading and writing, by explicitly passing the mode
parameter to the open_ostream
function. If you don't specify this parameter, it defaults to std::ios_base::out
.

I run my Android app (based on Java), and it works. Next, I add to my app code:
FirebaseFirestore fdb = FirebaseFirestore.getInstance();
This code I got from the official Android site https://firebase.google.com/docs/firestore/quickstart
App runs, but next the running device shows the message "app has stopped".
I use a device simulator available in Android Studio.
It is my first Android app, and I can't understand what is going.

...ANSWER
Answered 2021-Jun-09 at 03:39At the end of your log, just before the initial crash. there is a warning:
Default FirebaseApp failed to initialize because no default options were found. This usually means that com.google.gms:google-services was not applied to your gradle project.
simply adding com.google.gms:google-services
should fix any issues you have, if you have issues, ensure your Gradle cache is cleared or run without the build cache
--no-build-cache
