trifl | trifling functional views

My particle simulation is using up too much ram. What's concerning to me isn't the amount in and of itself, but the fact that it grows exponentially when I have reason to believe that it should not. I am using CUDA, which is the component I added most recently and thus what I suspect to be causing the issue. I have determined that it is not (only) a problem within the kernel, as the ram usage grows even when the kernel is not being run. I suspect it has to do with the way I am allocating memory, but I do not understand where I went wrong. I apologize for such a trifling question, I am new to CUDA (if that wasn't obvious). Here's the spaghetti in question, thank you for your time.

I'd like to profile my Go HTTP server application to see if there are places where it can be optimized. I'm using the fasthttp package with the fasthttp/router package, and I'm struggling to figure out how to hook up pprof.

The basic setup looks like this, obviously very abridged:

I have a component called flash that is intended to be in the DOM only for 5 seconds (it's a message informing the user that he has sent the post successfully) and I want it to start fading away after 2 seconds, so that after 5 seconds when it's removed from the DOM it already has visibility set to 0. To achieve this, in the parent component I setTimeout() and send a prop containing a boolean set to true to the flash component, where it has an if waiting for that boolean and when it gets it, it assigns a new class to that component to make it fade away. It all sounds perfect, but unfortunately it doesn't work at all... I tried updating the class within the flash component but it also doesn't work... Maybe you can come up with something? I'm sure that sending flash messages in react with pre-arranged components is a trifle in React, but I just can't think of any way of doing it!

Parent component:

I would like to implement functionality for being able to search a QPlainTextEdit for a query string, and display all matched lines in a table. Selecting a row in the table should move the cursor to the correct line in the document.

Below is a working example that finds all matches and displays them in a table. How can I get to the selected line number in the string that the plaintextedit holds? I could instead use the match.capturedEnd() and match.capturedStart() to show the matches, but line numbers are a more intuitive thing to think of, rather than the character index matches.

I want to create something that looks like below.

Few bordered boxes with equal vertical spacing.

After a bit of research, this is the best I can come up with.

I have tried a handful of ways to try and get my models to populate from this Alamofire GET call. Not sure what I am missing. I will include the JSON that is coming over as "data" as well.

I have a variable named "one" which takes the string value "Robby" how do I style this variable? for example, set the color to red

I'm experiencing a JavaScript error on a pen on codepen.io.

TypeError: window.CP is undefined

I tried to look it up and understood that it's connected to an infinite loop protection, but I can't find a way to solve the problem.

Here is the link to the pen on CodePen (where it doesn't work) and to a JSFiddle (where it works).

Here is the code on the snippet (where it also works).

(The green block is supposed to change color when you scroll)

I have successfully indexed content with elasticsearch, but I am having troubles when trying to query content.

What I want to do is to search all docs that both contains value "ipsum" (in any of it's terms) AND term "type" should be equal to "cq:Page".

I am using High Level Rest Java Client. Tried with filtering and with Boolquery but it returns zero results.
