QUESTION
I was reading this code (source):
...ANSWER
Answered 2021-Jun-16 at 02:16The n2 - n1
in the case of a negative number as a result when converted to bool
will yield true
. So n1
turns out to be less than n2
. That's why it is a bad practice to use int
s in such Boolean context.
Yes, as stated in the documentation:
...comparison function object which returns true if the first argument is less than the second
But the implementation of the comparison here leads to failure. Try this and see for yourself:

I built an app using Django 3.2.3., but when I try to settup my javascript code for the HTML, it doesn't work. I have read this post Django Static Files Development and follow the instructions, but it doesn't resolve my issue.
Also I couldn't find TEMPLATE_CONTEXT_PROCESSORS
, according to this post no TEMPLATE_CONTEXT_PROCESSORS in django, from 1.7 Django and later, TEMPLATE_CONTEXT_PROCESSORS
is the same as TEMPLATE
to config django.core.context_processors.static
but when I paste that code, turns in error saying django.core.context_processors.static
doesn't exist.
I don't have idea why my javascript' script isn't working.

The way you handle static wrong, remove the static dirs in your INSTALLED_APPS out of STATIC_DIRS and set a STATIC_ROOT then collectstatic again.
Add the following as django documentation to your urls.py

QUESTION
I am trying to create a shopping cart in JavaScript. When I click on the button, the price of item should increase according to the number of times I have clicked on the button. I've tried the below code but it's not working. The problem is that after clicking few times the multiplication goes like this:
suppose initial price =49
49 x 1
49 x 2
94 x 3
282 x 4 (it should be 49 x 4);
I have modified the code,it works fine in console.log()
but gives different result if I assign the variable newPrice to document.getElementById().innerHTML
ANSWER
Answered 2021-Jun-15 at 12:34I think this
const newprice = document.getElementById("discount").innerHTML *=counter;
should be
const newprice = document.getElementById("discount").innerHTML +=counter;
note the +
and not the *
before the =counter
. the plus is adding the star is multiplying.
QUESTION
I tried 5 different implementations of the Sobel operator in Python, one of which I implemented myself, and the results are radically different.
My questions is similar to this one, but there are still differences I don't understand with the other implementations.
Is there any agreed on definition of the Sobel operator, and is it always synonymous to "image gradient"?
Even the definition of the Sobel kernel is different from source to source, according to Wikipedia it is [[1, 0, -1],[2, 0, -2],[1, 0, -1]]
, but according to other sources it is [[-1, 0, 1],[-2, 0, 2],[-1, 0, 1]]
.
Here is my code where I tried the different techniques:
...ANSWER
Answered 2021-Jun-15 at 14:22according to wikipedia it's [[1, 0, -1],[2, 0, -2],[1, 0, 1]] but according to other sources it's [[-1, 0, 1],[-2, 0, 2],[-1, 0, 1]]
Both are used for detecting vertical edges. Difference here is how these kernels mark "left" and "right" edges.
For simplicity sake lets consider 1D example, and let array be
[0, 0, 255, 255, 255]
then if we calculate using padding then
- kernel
[2, 0, -2]
gives[0, -510, -510, 0, 0]
- kernel
[-2, 0, 2]
gives[0, 510, 510, 0, 0]
As you can see abrupt increase in value was marked with negative values by first kernel and positive values by second. Note that is is relevant only if you need to discriminate left vs right edges, when you want just to find vertical edges, you might use any of these 2 aboves and then get absolute value.

QUESTION
I've read a number of questions on this same error but couldn't understand whats happening in my case. On the other questions this error is caused by an object being used as a React child or caused by more than one prop attribute being passed.
I'm trying to set formik
and yup
to validate a Day Field according to a Month Field, both using react-select
, in such way that if the month is February then the max day allowed is 29. Just that...
I've managed to reproduce the error in a Codesandbox: https://codesandbox.io/s/formik-yup-reactselect-rmd9f?file=/src/App.js
If you select the Day 29 and any month, then it works, but if you select day 30 and February then this error appears and I can't find out what's wrong:
Uncaught Error: Objects are not valid as a React child (found: object with keys {value}). If you meant to render a collection of children, use an array instead.

Changing the PowerShell Window FontTo do this, right-click your PowerShell window and head to "Properties"
There, you can choose the header "Font" and change your font to Cascadia Code PL".
This should fix the problem. If you still experience some weird characters, you might need to install a Nerd Font instead.
Changing the VS Code Terminal FontTo use the font in the VS Code Terminal, head to Settings.
Searching for "integrated terminal font family" should bring up the setting you need to edit. Here, add your font 'Cascadia Code PL' on the very front of the setting and save.
You should now be able to open a terminal and use the PL prompt.
