clist aims to be an RFC-compliant mailing list manager. When users send an email to a list, clist delivers that email to other subscribers of that list. Users can manage their subscriptions by sending commands to clist over email. clist can manage multiple lists, each with its own set of subscribers. clist is intended to be used by a single organization and will provide a sane set of defaults and a simple configuration.

QUESTION
I'm currently coding a program to monitor certain computers on our network. To this end, I have a Monitor object, that I have made a singleton, to ensure that all functions that communicate with it, get the same data. This object maintains a list of ComputerData objects, and provides the public functions to add, remove, and update these objects.
I've written a quick test harness that gets the instance of the monitor, and then sends a couple of testdata ComputerData objects (passing them using a BYVAL)
However I notice that if I change the testdata ComputerData object, AFTER I have passed it to monitor, that the object stored in Monitors list is also updated. Like it had been passed as BYREF.

Answered 2022-Mar-31 at 10:36Passing by value means passing a copy of the contents of a variable. If a variable is a reference type then the variable contains a reference to an object. Passing that by value means passing a copy of the reference, not a copy of the object. Passing a method parameter by value is exactly the same as assigning one variable to another. If you did this:

I am trying to create a student mark list. Firstly, i have to create both student and course list. However, i'm stuck at this problem. Here is my code:
...ANSWER
Answered 2022-Mar-31 at 07:14The first for loop inside the method studentList()
is looping twice, as the range(student.count) is evaluated to 2. Notice that the student.count got the value informed at the first input('Enter number of students:')
, which was 2.
Besides the twice loop, the values being added to the list inside the loop doesn't change, as they refer to properties of the same instance of the object student:

QUESTION
Refer to link. Link is to the project "Scroll-Animation" I am cloning in local browser to practice front-end.
I have two buttons, +, -. The '+' adds new boxes, the '-' removes boxes from the body. I implemented the '+' but it seems the styling for boxes is not working. That is, it seems to add the "div" elements I created to body but the div's are not style like I have them in .css file for .box { ... }
Any help with how to fix this is greatly appreciated. Thanks!

Answered 2022-Mar-18 at 03:38I think the problem is after you add a new box, but afterward you don't query all boxes again in slideBox

Answered 2021-Dec-09 at 14:07You can approach this problem by considering that your "greater than" relation is a little more complex than just Python's >
:
- for two numbers,
>
applies, - for two strings,
>
applies, - between any number and any string, the string is "greater than" the number.
Now, implement a function that does that, and use it instead of >
in your algorithm.
Let's write that logic into function my_greater_than

QUESTION
I've been working on a Android Project (A Basic College Information App), I have three main activities, the user goes in like, Goal/Course Select activity
-> CollegeList activity
-> College Details Activity
. Now When I press back on College Details Activity
it crashes with this Error:
Attempt to invoke virtual method 'int java.lang.String.hashCode()' on a null object reference
Below are the files/code which I think might be responsible for this.....
CollegeListActivity.java file
...ANSWER
Answered 2021-Nov-26 at 19:34This will probably go away if you don't override onBackPressed
in CollegeDetailsActivity
. Instead of going back to an activity that had a valid "Title" string extra, the code you posted will go to a new activity where "Title" isn't defined, then get a NullPointerException since courseName
will be null in initData
(which the error message tells you results in an error on line 81 in that method). Using a null string in a switch results in that type of error
Just remove your onBackPressed
entirely in CollegeDetailsActivity
.
