stutter | Implement a Lisp , in C , from scratch , no libs | Interpreter library

I'm implementing a dark theme on my website using tailwind classes. For example:

And for some reason, whenever I change my theme the transition isn't smooth but laggy and stuttering. I've noticed that with the increase of dark-styled elements on the page, the lag has gotten worse.

I'm not sure if this is actually a tailwind problem or a general CSS performance problem in the browser.

UPDATE

After some test I've come to the conclusion that it actually has nothing to do with transitions but with CSS itself.

I have a lot of elements on the page with dark classes set initially and then whenever I change the theme I just add/remove 'dark' class in . I have may be 50 elements on the page which change their text color and background color and all of them are laggy whenever the theme gets changed. The lag is similar to when you have a memory leak or a loop. It stutters then loads all at once and stuff like that.

So I guess my question is how to optimize CSS performance in this case? or overall?

UPDATE 2

According to Performance page in devtools I'm dropping a lot of frames when changing the theme. And it actually feels like I'm getting 5fps. Here is a screenshot of Performance page prnt.sc/Zz6T88ZFs6Fp. I'm not sure how to read it, may be somebody can give some useful info

If anyone has ever faced/solved this problem, I'd greatly appreciate your advice

I am trying to use the loop option on a AVPro Media Player, with a small (6sec, 25MB) perfectly looped video, but there is a small "freeze" when looping.

My code is very simple:

I'm trying to learn the basics of SQL by setting up a simple database in SQLite.

I created two tables, "people" and "departments"

The people table has three columns: ID(primary key), Name and Age;

The departments table has two columns: ID(primary key) and DeptName;

A single person can work in more than one department, so I created a third table "P2D" with two columns, "PpID" and "DpID" constrained to the ID columns of the other two tables. Maybe there's a better way to do this, but that's what I figured out (is it?)

Now, I need to make a query to display people name, age and departments. I made this:

When stress-testing a TCP server of mine with a large number of connections, I figured that connection requests will throw a SocketException after some time. The exception displays randomly either

Only one usage of each socket address (protocol/network address/port) is normally permitted.

or

No connection could be made because the target machine actively refused it.

as its message.

This happens usually but randomly after some seconds and some tens of thousands of connects and disconnects. To connect, I use the local end point IPEndPoint clientEndPoint = new(IPAddress.Any, 0);, which I believe would give me the next free ephemeral port.

To isolate the issue, I wrote this simple program that runs both a TCP server and many parallel clients for a simple counter:

Can anyone help me make this progessbar smoother?

This is my javascript code for the progressbar. I hope you can do something with it and help me with it. I would like to improve the smoothness because it is very stuttering at a higher runtime.

My goal is to make a swinging star-pendulum.

It works as expected in Chrome and Opera browsers but stutters in Firefox.

I have tried adding -moz prefixes for compatibility but the problem still exists.

Any insight is appreciated.

I'm reading this and this doc. But I'm still new to multi-threading and I cannot fully understand these topic.

Qt 6.2.0 under Ubuntu 20.04. Basically I have this function:

My goal is letting the user edit their user data from a csv file. The content of the csv file ("bingus.csv") looks something like this:

It occurs on iOS15/iPhone12 series of devices.

Multiple CollectionViews are paged with each timer, but paging does not work normally only on iOS15/iPhone12 devices.

The paging is stuttering and the animation is not working normally.

I tried implementing a timer using Rx, but the symptoms are the same.

It operates normally on other devices, other iOS versions.

Has anyone experienced the same issue as me?
