QUESTION
Hey guys given the example below in C when operating on a 64bit system as i understand, a pointer is 8 byte. Wouldn't the calloc here allocate too little memory as it takes the sizeof(int) which is 4 bytes? Thing is, this still works. Does it overwrite the memory? Would love some clarity on this.
Bonus question: if i remove the type casting (int*) i sometimes get a warning "invalid conversion from 'void*' to 'int*', does this mean it still works considering the warning?
...ANSWER

is allocating the amount of memory you asked for on the heap. The pointer is allocated by your compiler either in registers or on the stack. In this case, calloc
is actually allocating enough memory for 4 int
s on the heap (which on most systems is going to be 16 bytes, but for the arduino uno it would be 8 because the sizeof(int)
is 2), then storing the pointer to that allocated memory in your register/stack location.
For the bonus question: Arduino uses C++ instead of C, and that means that it uses C++'s stronger type system. void *
and int *
are different types, so it's complaining. You should cast the return value of malloc
when using C++.

...ANSWER
Answered 2021-Jun-15 at 17:13Short answer: You can't.
It was possible in MongoDB version <= 3.6 where there was an option to bypass the validation completely using the check_keys=False
option. But this option is deprecated ever since.
Although MongoDB has bypass_document_validation=True
in newer versions, it won't bypass the .
character for obvious reasons.
There is an open issue regarding this on JIRA (SERVER-30575) and it is still open. Also, the PyMongo
specific issue related to this was raised once PYTHON-1522.
So until the SERVER-30575 issue fixed, you have no other choice.
I would suggest you rearrange your schema design to embed the key name as a value to a different key.
Something like this:

Hey just doing some exercises in c, one is saying to replace tabs in the input string with any other characters , i restrict myself to only using getchar()
, no gets() fgets()
etc..., as my learning book didn't catch it yet, so i tried to not break the flow, the code below just printf()
the same line it receives, can you please examine why ?

, which is used inc != '\n'
, is not initialized at first. Its initial value is indeterminate and using is value without initializng invokes undefined behavior.- You are checking
line[i] != '\0'
, but you never assigned'\0'
toline
unless'\0'
is read from the stream. - You should initialize
i
before the second loop and updatei
during the second loop. - Return values of
getchar()
should be assigned toint
to distinguish betweenEOF
and an valid character. - You should perform index check not to cause buffer overrun.

QUESTION
Hey to all in the forum
I use JSF Mojarra implementation, version JSF 2.2
I need desperately a help on this.
- I have a snippet of my page.
- I have a custom component "example_result.xhtml" used in the page.
- I have my BackingBean.java Be aware please that this code is not the real code I made. If you run it, it will be very ugly maybe because I deleted all the css classes and I kept only the hot stuff I need to show you my problem.
Everything is inside 1 form.
The 5 "h:selectManyCheckbox" (in my code I have 8 or 9)
In the form I have 5 "h:selectManyCheckbox" which are using values in the "value" attribute for different cases (javaFrameworks2Values, javaFrameworks3Values,...), and the "f:selectItems" use arrays of "SelectItem" (javaFrameworksSelectItems2, javaFrameworksSelectItems3...) created for these different cases, just to make some examples for me to understand how all the selectOne and selectMany components work. The ideas for this, about different cases were taken from these links: "https://stackoverflow.com/tags/selectonemenu/info" and "https://mkyong.com/jsf2/jsf-2-checkboxes-example".
After I have 2 commandButtons
1 for submit, and 1 for reset the values.
Display the values
After I display the results of the values of the "h:selectManyCheckbox" via the "example_result.xhtml".
You can see the 4th "h:selectManyCheckbox" that is the only one different, because it has the attribute "required" with the attribute "requiredMessage". With it there is a "h:message" to display the validation error.
In the BackingBean (which is Spring Bean, but it works perfectly good - sorry I don't want ejbs 3.x), I have initialized:
- The values of the SelectItems and
- The values of the "value" attribute, where the values of the "h:selectManyCheckbox" will be stored to be displayed later. [The code is completely castrated, to make it readable snippet].
When the page is rendered, I select checkBoxes (e.g. the 2 last, because the 2 first are initials) from all the "h:selectManyCheckbox". When I say that select from all, I mean it. And from the 4th with the "required" attribute. I try in the buttons (see in the code) the "Effort 1", or "Effort 2", or "Effort 3" (in the "f:ajax" in the buttons) and the result outputs in the last part are displayed and updated like a candy. Without any problem. To achive this with the composite component I googled and tried a lot. But I made it.
Then it comes the time to try the 4th to see the validation error of the "required" attribute.
I select again from all as before, but not from all. NOT from the 4th "h:selectManyCheckbox" this time. I select nothing from the 4th "h:selectManyCheckbox" to ckeck the validator error message ("requiredMessage"). The result is: It displays the message of error (GOOD until now), BUT this time it does not update anything from the others "h:selectManyCheckbox" to the output results at the end, and it does not reset the values as well as it was doing before (when I selected from all and from the 4th as well).
I understand that it says: as long as in the form the 4th failed with validation error, all the other "h:selectManyCheckbox" will not update the output results (something like wanting to fail all the others too).
But what really happes here?
- It does not give the values to the "h:selectManyCheckbox", to be updated to the output?
- It gives the vales to the "h:selectManyCheckbox" normally, BUT it just not updates the output?
The other efforts in the "f:ajax" in the buttons, are just efforts maybe to solve the problem but in these cases they don't even display the error message in the 4th case and of cource they don't update the other output results as well (again). But no message error as well.
I don't know if the problem is clear to you. I can explain in the discussion better so I can clarify the situation better. [To be honnet it took me 1 and half hour to write all this thing]
Thanks a lot in advance

Answered 2021-Jun-15 at 14:11After a lot of discussing with the only person who wanted to help to my issue here (and I thank him @WoAiNii for this a lot), I decided to post my solution:
I will make 5 different forms with 5 set of buttons (submit/reset), to make escalate this problem, for 5 so much related components in the form.
But my question is open: Why this is happening, what rule in JSF in this case is taking place and makes this situation. Anyone, comes with an explanation:
- Thomas: this is a rule in JSF, or
- is a JSF bug, or
- this happens in these cases, or... whatever...,
I will be glad to read it here so I will learn better, and others to will learn from these ideas of yours. Thanks a lot

QUESTION
Hey there stackoverflow
I am currently building a course application as part of my laravel project.
My problem lies in how the eloquent handle model relations, i'm still kinda new to eloquent, so hopefully you can answer my question.
The structure
The Course has many episodes and each episode has many sections.
Which means I have 3 tables in the DB. Courses -> course_episodes -> course_episode_sections
ID table is where i connect courses with users - course_users.
Right now i can create courses and and put in all the data correctly.
The Problem
I need to retrieve all the courses and its nested children that the user has bought, which is connected in the course_users table with columns course_id and user_id
Course structure
Same stucture in DB
...ANSWER
Answered 2021-Jun-14 at 15:14According to your explanation, course_users table holds many-to-many relationship between Course and User model. In case of a many-to-many relationship, you actually don't need a CourseUser model. This kind of table which holds many-to-many relationship is called pivot table. Read more from the Official Documentation
I am defining only the relationships with your Course, User, CourseEpisode, CourseEpisodeSection models.
