You'll need to find a different approach.
QUESTION
I am using the raylib and it uses the 32 bit RGBA colours. I searched in a cheatsheet, but I could not find any appropriate routine. What I want to do is multiply two colours as if they were vec4
s in opengl (each channel ranging from 0 to 1). I actually already successfully
performed the multiplication but it is rather slow operation involving lot of floating point arithmetic for something so simple:

QUESTION
I am wondering besides these below mathematical expressions are there any other functions available to call inside a smart contract? Like math functions, like pi, sin, cosine, random() etc?
I am wondering if one can write smart contracts that require a little more than just basic arithmetic.

...ANSWER
Answered 2021-Jun-03 at 18:25Solidity doesn't natively support storing floating point numbers both in storage and memory, probably because the EVM (Ethereum Virtual Machine; underlying layer) doesn't support it.
It allows working with them to some extent such as uint two = 3 / 1.5;
.
So most floating point operations are usually done by defining a uint256
(256bit unsigned integer) number and another number defining the decimal length.
For example token contracts generally use 18 decimal places:
QUESTION
Scenario: As an Administrator I need to invalidate a user's session (log them out) after I update the user's password. This is in accordance with best practices as per https://cheatsheetseries.owasp.org/cheatsheets/Session_Management_Cheat_Sheet.html#Renew_the_Session_ID_After_Any_Privilege_Level_Change
I am using Devise and I saw here https://stackoverflow.com/a/45756884/664675 there is a config to log the user out: config.sign_in_after_reset_password = false
However, I have enabled this config in my devise.rb
but the user remains logged in. Not sure why that is?
I am also using Redis as the session_store
ANSWER
Answered 2021-Jun-02 at 07:12the flag sign_in_after_reset_password
does not relate to logout
user at all, sign_in_after_reset_password = false
imply that in case a user update his account password by himself then do not automatically sign-in his account again, and that logic happen only on PasswordsController#update.
So you as admin try to change password of another user in a custom controller, of course it's not logout user no matter the value of sign_in_after_reset_password
is.
devise
use gem warden
to logout
user (in other word: destroy user session) and warden
base on request session
not base on database
, that mean there's no way an admin can get another user's session to reset, so you can not force logout another user by only devise
, you need to handle this feature outside devise (such as add session
to user
table or a devise hook something like timeoutable)

QUESTION
I'm using the Ursina engine to create a 3D game. However, when i try to load the FirstPersonCharacter, all I got is a grey background (normal) and a very small magenta square, in the center, tilted at 45°. What is that ?
I was first trying to make my own mechanics for a first person character, move the camera according to the mouse position (I have this), and I was playing with math and stuff for movements... I was looking at this video (https://www.youtube.com/watch?v=DHSRaVeQxIk) for totally something else, and I found out about the FirstPersonController.
But, with the (almost) same code as him, it doesn't work ! What's that issue, has someone already ran into it ? Is FirstPersonController broken ? Or is my brain broken ?
Edit : found out in the ursina cheatsheet that the small magenta tilted square is the cursor. But I still can't move, can't have gravity or anything ? And I can't see my floor.
Second edit : using some piece of code the ursina cheatsheet provided, arranged, I can now see my floor. But I can only move the camera on 1 axis (up and down), I can't move, no gravity, nothing...
Here is my code :
...ANSWER
Answered 2021-May-22 at 07:57There is gravity and it has the effect of letting the player fall into infinity. When you move the mouse around to look up, you will see the cubes disappearing into the distance.
The solution is to add collider='box'
to your floor cubes to stop the player from falling through. Note that the starting point seems to be inside one of the cubes so you have to jump out of it (using the space bar) or slightly lower your floor cubes' position.
QUESTION
I'm noticing some odd behavior with R regex quantifiers written as either {min, max}
(as recommend in the stringr cheatsheet) vs. as {min - max}
, when using the pointblank package. I expect the regexes to work with {min, max}
and fail with {min - max}
. However, in the two examples below, one works with {min, max}
and one works with {min - max}
.
Example 1 works as expected: pattern_comma
works and pattern_dash
does not. But example 2 works unexpectedly: doi_pattern_comma
does not work and doi_pattern_dash
does work.
Any suggestions about this regex? Or might this be a bug in pointblank (in which case I can open an issue there)?
Thank you, SO community!
...ANSWER
Answered 2021-May-09 at 21:52You must not doubt: {min-max}
quantifier does not exist, you need to use
{min,max}
. \d{4-9}
throws an exception (try it with sub
and you will get invalid regular expression '\d{4-9}', reason 'Invalid contents of {}'
).
Next, the second issue is that the regex is parsed with the default TRE regex engine, and you can't use shorthand character classes like \w
or \W
inside bracket expressions there, so you need to use [:alnum:]_
instead of \w
inside square brackets.
Now, that you know the right regex:

QUESTION
- RTLib has auto-cleanup and I want to keep it.
- In some cases though, I want to reuse the render result of my component in that way (tests are simplified):
ANSWER
Answered 2021-Mar-22 at 16:06This question is a bit subjective, but as the creator of the library you're using you may be interested in my opinion (especially since you emailed me a link to this) 😉
The alternative you mention is the recommended approach. Read more in Write fewer, longer tests.
Also, I noticed you're calling the return value of render
Wrapper
which is old cruft from enzyme and I recommend avoiding that as well. Read more about that in Common mistakes with React Testing Library.
I hope that's helpful.
