Are IFRAMEs inherently unable to display file:/// URLs?
Yes, the browser and webserver are on the same machine!
Whenever I try to embed a HTML file from outside of the WWW root in an iframe
, thus using the file:///
URL syntax, it is ignored. No error message logged or anything. Just nothing is done whatsoever.
If I change the path from file:///C:\blablabla.html
to ./blablabla.html
, and put the file in the WWW root, it will display the HTML page in the iframe. So it’s not some kind of fundamental issue with displaying iframes or anything. I have tried both with and without URL-encoding the C:\...
part.
Are IFRAME
s inherently unable to display file:///
URIs, even though the MozDev page mentions no restrictions whatsoever for the src
attribute? https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe
Unity Unable to blend 2D Light renderers
I’ve followed the documentation on Unity regarding 2D lighting. It said to turn on Alpha blending in the options. But this is how it turns out: If Alpha blending is off:
If Alpha blending is on:
I’m not entirely sure why it’s turning black. These are my settings for the 2D light:
I’ve checked my layers, specifically the tile map floor, and it’s on the Default layer.
I just want my lights to blend well.
Why both DSolve and NDSolve are unable to solve a second-order differential equation?
I am trying to solve a recurrence relation using generating functions method. After some long calculations, I have arrived to this second-order differential equation: $ 0.5 x^5 y”(x)+(2x^4+x^3)y'(x)+\left(x^3+x^2+x-1\right)y(x)+1=0$
and these conditions: $ y(0)=1, y'(0)=1$ . $ y(x)$ is the function that needs to be expanded as Taylor Series at $ x=0$ to obtain the sequence from the coefficients. However, when I try to solve it both using DSolve and NDSolve, I have no luck. With DSolve it just returns the request itself:
$ $ \text{DSolve}\left[\left\{0.5 x^5 y”(x)+(2. x+1) x^3 y'(x)+\left(1. x^3+x^2+x-1\right)y(x)+1=0,y(0)=1,y'(0)=1\right\},y,x\right]$ $
And with NDSolve I just receive errors and no equation:
Power::infy: Infinite expression 1/0.^5 encountered. Infinity::indet: Indeterminate expression 0. ComplexInfinity encountered. NDSolve::ndnum: Encountered non-numerical value for a derivative at x == 0.`.
$ \text{NDSolve}\left[\left\{0.5 x^5 y”(x)+(2. x+1) x^3 y'(x)+\left(1. x^3+x^2+x-1\right)y(x)+1=0,y(0)=1,y'(0)=1\right\},y,\{x,0,1\}\right]$
How could I resolve this problem?
Unable to create dynamic button link after selecting product
This is my website- https://aceworkz.promo/. I used WPForms to create form across all the websites. After submitting information the user will redirect to this page-https://aceworkz.promo/amazon-2/. When the user selects a specific product he will redirect to the Amazon review page. The review link will be different for every product. My question is how can I add a dynamic button link for each product? I’m using the Elementor page builder to create this button. Thanks guys for your help!
Unable to rotate box2d body with torque if revolute joint introduced
I created a simple body (PLAYER) which, as speed increased the angle of the body increases slightly. I set the torque property based on velocity, to change the body’s angle, and it looks like the player is leaning forward as he runs. Great.
I wanted to prevent my PLAYER from flipping over (when hitting other bodies), so I created a second body and placed a revolute joint between them. The second body has rotation disabled, and is dynamic. I discovered that I did not need to apply any angle limits to prevent flipping, since the joint seemed to resist rotation. The player actually rights himself if flipped on his side. (The joint seems to want to return to 0 angle). The motor is disabled, no motor speed, no motor torque. Still, the joint returns to 0′.
The PLAYER still rotates a bit when hitting other bodies, but I can no longer rotate the body with any torque value (to make him lean forward). Why? I need to restore the leaning effect.
I don’t understand why the second body + revolute joint prevent rotation due to any torque applied. Can someone explain, and offer solution?
Unable to save or update posts with Emoji
I host my WordPress (v5.4.2) blog on 000webhost.com and I am unable to save any post with emoji characters. I get this error Updating failed. Could not update post in the database
I have tried changing these lines in wp-config.php
define( 'DB_CHARSET', 'utf8mb4' ); define( 'DB_COLLATE', 'utf8mb4_unicode_ci' );
I also migrated all my tables in MySQL to utf8mb4_unicode_ci
with the below step.
But none of these worked, what I am missing? Please help My WordPress version: 5.4.2
Unable to find proxies from “harvest proxies”
Hello Admin,
This is what I do –
Under Select Harvester and Proxies I click on Manage and I harvest the proxies – no problem.
First time I used I ran it ofr like 5 mins and I tested it…5-10 google passes proxies were tested Okay but just out of curiosity I filtered Google only proxies and retested them again. Then the result showed failed to all.
Then I thought it mightbe because I only ran it for 5 mins. This time I ran it for 4.5 hours and, got some passed google proxies, and then filtered them, again just out of curiosity I retested them and the filtered results failed again.
Thus, I am not able to harvest public google proxies.
WHat am I doing wrong here?
Cheers!
