QUESTION
I'm building a scripts to compare lines from two text files but I got the thing wrong looping through each line in the 2 files. I don't know why but it just didn't do anything for me as I wanted it in the code to do. Here is the sample text in the text files I'm processing.
...ANSWER
Answered 2020-Jun-23 at 08:45I'm not quite sure what your aim is in comparing, but I would parse the files in a single loop, resulting in an array of two PsCustomObject arrays like this:

QUESTION
I'm frequently installing multiple instances of an umbrella Helm chart across multiple namespaces for testing. I'd like to continue using the randomly generated names, but also be able to tear down multiple releases of the same chart in one command that doesn't need to change for each new release name.
So for charts like this:
...ANSWER
Answered 2018-Jul-24 at 01:17You could try:
helm delete $(helm ls | awk '$9 ~ /SEARCH/ { print $1 }')
Replacing SEARCH
with whatever chart name pattern you want to use
It gets thrown off a little because awk is going to delimit on the spaces, which the timestamp has several of.
So what would traditionally be tab delimited:
1=NAME
2=REVISION
3=UPDATED
4=STATUS
5=CHART
6=NAMESPACE
becomes:
1=mottled-whippet
2=1
3=Fri
4=Jul
5=20
6=13:15:45
7=2018
8=DEPLOYED
9=postgresql-0.15.0
10=namespace
QUESTION
Can I use Type Parameters with multiple bounds to guarantee at compile-time that a container's contents conform to certain traits?
This is probably best expressed in code:
...ANSWER
Answered 2019-Jun-11 at 05:20Basically, no you can't. The conceptual reason is in how generic types are bound. When you create a class like Zoo
, T
doesn't mean "any type that extends Animal
", it means, "a specific type that extends Animal
that will be provided at runtime". Normally this lets you do what you want, but your case appears to be testing the bounds (ba-dum-tiss) of this system.
I think the more nitty-gritty answer will have to go into the wildcard (?
) binding system - something about ? extends A & B
means that it can't prove that a type C
that extends A & B & D
actually matches.
A (worse) design that accomplishes your goal looks like this:
QUESTION
Working on an existing expand/collapse "FAQ" accordion page and looking to get the "expand/collapse" feature to work correctly.
I managed to get the page to start off with everything collapsed, but when I click on any column to expand and then click on another, the original one does not collapse.
Importantly, I would like to keep the search feature intact.
...ANSWER
Answered 2019-May-03 at 12:32If you want the panels to start out collapsed, don't use the in
class.
Calling $('.collapse').collapse();
doesn't collapse your panels, it reactivates the .collapse
elements with the default options, overriding .in
(so the panels are closed) and data-parent
(so you lose the one-panel-at-a-time behavior).
You also don't need to define the :contains
pseudo-selector three times on every keypress. Once is enough. And you don't need to explicitly loop over all #accordion
's .panel
s, just use a sufficiently broad selector.
QUESTION
So I am having trouble with this code that I have made. What I want it to do is that the user inputs either "real" or "fake" and then they click the submit button and the program outputs this sentence "Your random animal is..." (It will have a random animal in the dots). What I can't get working is the get_animal function. So what this does is it outputs the response to the user. But I can't get it to work with my GUI.
Here is my code:

Answered 2018-Jun-19 at 01:42You need to return the value, not print it. Like so:
QUESTION
I have this code here simply trying to create a file that the name is chosen from a randomized array. Why does it output incorrectly?
Code:
...ANSWER
Answered 2018-Mar-21 at 16:04Alex K identified your primary problem in his comment - you are missing setlocal enableDelayedExpansion
.
But you have another problem - your array contains 6 values, but you are randomly selecting an index between 1 and 4 instead of between 1 and 6.
You should use set /a operator=%random%%%i+1
. Note that true environment variables do not need to be expanded when used with SET /A.
QUESTION
I have a static variable named debug
that I'm trying to access in my class that is generating an error.
Access of possibly undefined property debug
The property is defined on the base class.
...ANSWER
Answered 2018-Feb-08 at 05:21That's correct. Static variables are not inherited by subclasses. This is documented here, which also suggests working around it by declaring an instance variable with the same name. Not sure how useful of a workaround that is, since you might as well change the static variable to an instance one instead of having both (unless you really need to call Animal.debug
elsewhere), but it's AS3, it's there.

I have Multiple Choices With Multiple Answer.I Want to different options with correct answer as well as wrong answer.I had already done this type of question with single answer but in this case correct answer may be more than one. Differentiate Choices with Correct Answer using PHP. I had tried like below code but I will get for only single value check not for all.I dont know why
...ANSWER
Answered 2017-Mar-26 at 11:35You have to declare the flags as a array, and push choices to that array , in this way if there are multiple choices, the stored value does not get replaced. in the flags.
