illusion | For now , Illusion is a convenience layer on top of Vulkan | Graphics library

Sometimes it is needed to draw categorical values on a regular grid to show how they cover a certain area. In principle, the plot() function is a good fit for this, but there is a problem that is needed to adjust the size of the icons each time to create the illusion of a solid cover. When changing the coverage of the image, the old size becomes irrelevant and is needed to adjust it again. Is there a technique to adjust this size automatically?

I am currently training on React and am having a problem. As you can see on the screenshot, I would like to click on the product name to redirect to a description page of this product. I used react-router-dom for the illusion of multiple pages in the app but I can't seem to display the API data on another page. I would like to be able to click on a product title to be able to access the details of this product.

You will find my code below

Thank you very much in advance for your explanations

I have an express app with MongoDB. It creates a user id for each user document. This user id also get encoded in jwt, which creates an illusion for new devs that user id must not be sent to front end in plain text form.

Can someone explain how sending user id to front end can create security issues? As much as i know hackers can't create a jwt with it without my secret string. Neither my express app listens for this user id anywhere in backend. But its critical for frontend as it is being used as seller Id.

I'm having a bit of a mare with jQuery and I was hoping someone could clarify some bits for me. I'm under no illusion any of this is elegant or optimal, and I have NEVER got on with Javascript in any form so please don't judge me too harshly!

Basically, I've got a Wordpress plugin that works very well for most things I want it to do. The main thing is that it offers the ability to select the delivery method from the Woocommerce product menu page. But I've been asked for the available menu options to be filtered by delivery method and I can't see a way of doing this live on the page, so what I've come up with is a "simpler" solution. I'm intending to set up three different page implementations of the menu, one for each of the delivery options (deliver, pick up and eat in), each with categories filtered via shortcode for that delivery method. When the page loads I've got jQuery setting the default option for the dropdown to match that page and then whenever the dropdown is changed from this option it can trigger a redirect to one of the other relevant pages.

I know this is a messy way of doing it, but I have no idea how or even if I could filter the products on the menu any other way, but if someone has a suggestion I'd love to hear it!

Anyway, I've got this partially working. I can set the dropdown default on page load easily enough, and I've managed to get an if statement kind of working, but it only seems to work for the first option and no others. I also can briefly see ifelse undefined in the console before the page changes on a redirect. I've also tried to use a variable, but whenever I've tried using it in the if condition checks it just comes up as undefined or null even though I can view it on the previous line like this:

I am trying to make a part of a program that takes a users input, searches across several dictionaries to find a matching key, and then increase the corresponding entries value by 25.

I have trying achieve motion effect, even for standing objects.
Why? - I assume, my object will go to right for example.
But, I wanna create illusion in some part that object is still moving. Even if wasn't.
Later I wanna same effect for other obejcts.

Here is my example what I wanna achieve (more or less) - illusion object going to right in place:

I'm designing a Python terminal program. I use os.get_terminal_size() to get the dimensions of the terminal. However, print() appends \n and so it seems that the newline character gets pushed on to a new line i.e. I think a new line is added by Python and then another newline is added due to terminal text-wrapping that newline, causing an unwanted large space. See below:

The outer ---------- are the borders of the terminal window, and the ---------- under "Welcome" is the printed separator.

While I was trying to answer another person's question on stackoverflow about the difference between = and += in Python, I encountered the following problem:

Just wondering if anyone knows of anything to similar to clicking a feature (point) on an OpenLayers Map and it triggering a small pop-up form for completion?

I've found this in regards to adding text labels, but I don't want my label to appear... https://subscription.packtpub.com/book/web_development/9781785287756/3/ch03lvl1sec34/adding-text-labels-to-geometry-points

Realistically, I want an illusion for the user to have interactivity with a contact page map. They can draw a point on the map (this code is complete), but now I'd like to offer them the opportunity to click that point they've just drawn and add text in a pop-up - is this possible?
