kandi X-RAY | fast Summary
Fast, short for "Find AST", is a tool to search, prune, and edit Ruby ASTs. Ruby is a flexible language that allows us to write code in multiple different ways to achieve the same end result, and because of this it's hard to verify how the code was written without an AST.

QUESTION
I have the wackiest bug. Like....the wackiest! If any of ya'll want to put eyes on this, awesomesauce! I really appriciate it! I am creating a survey with REACT, Redux, SQL, HML, Material-ui, and CSS.
I've created a graph of information with am4charts using data from a database. Everything is working and will show up on the page......but not on page load. What I am seeing in my console is that the page will load, it fires off my get request but doesn't return with the data fast enough (I think). By the time that the get request loads, my graph has populated with no data.
Here is the code that I have for the page that I am rendering. What is really odd is that, once my code has run, I can cut a line of code (I've been using a console log). And then the graph will render and load.

Is there a simple adhoc way to execute a ILIKE query on all text columns of a table?
I know that there is a cell which contains "foobar". But the table has a lot of columns and only 50k rows, so searching all columns and rows should be fast.

QUESTION
I have a concave hull (not convex) that I have the points for eg: A,B,C,D,E. I've gotten the pairs of points that make up the outer edges. [A,B],[A,E],[C,D],[B,C],[E,D]. (This is a very simplified version)
I want to get the connected points in order (CW or CCW doesn't matter) so I can use them as a contour.
But the pairs are not ordered, you can see A goes to B, then A goes to E, etc. The only solution I had was searching for each point and its next pair sequentially in a loop
Is there a way to solve this using numpy only in a vectorized manner so that its fast for a large array of edges? I know shapely exists but I have trouble installing it and I'd prefer no external dependancies
this is my code:

QUESTION
hopefull someone can shed some light on this topic and here are some of my questions:
- How do big ecommerce websites manage their images for their websites?
- Is there any Best Practices should be consider when deciding where to keep websites images?
- I have heard to keep the images in multiple folder structure on the same server where the website is hosted so websites can render them easily and fast since they are all on same server - Is this the idea solution?
- How do professionals or big ecommerce handle images storage and maintain website images reliability and stability?
- Is Azure or AWS etc best place to store images for websites rendering?
Thanks in advance!
...ANSWER
Answered 2021-Jun-15 at 02:52Keeping the files in the same server comes with more risk, if your server crashes or region goes down your application stopped as well as your files not gonna render if you are using those files separately for different applications like mobile applications.
In this case, users will also face a high loading time for those media files if the users are not in the same zone as your application hosted.
The best practice to store the image/media files on some cloud storage like S3 or Azure Blob then connect it with some CDN like CloudFront or Azure CDN.
Now you can serve your media files via CDN which will act as a global caching system for your media files.

I don't really know where the error is, for me, it's still a mystery. But I'm using Laravel 8 to produce a project, it was working perfectly and randomly started to return this error and all projects started to return this error too.

QUESTION
I did some research and found this: Setting a fixed FPS in Pygame, Python 3 and this: pygame clock.tick() vs framerate in game main loop. It is similar to what I am asking.
So the clock.tick(FPS) caps the program to run at that FPS. The reason you do this is so you can control the FPS of the program and it makes it easier for time stuff like waits.
But how can I unlimited FPS and still control my FPS for time stuff like waits? From my understanding, this is not possible, due to the fact that clock.tick(FPS) caps the FPS and while not adding it in means unlimited FPS but you not being able to control the FPS.
So it seems to be a question of weather to cap you FPS for control or have your program run as fast as possible, but without control.
In conclusion, what I am asking is four questions;
- Pros and cons of capping your
FPS - Pros and cons of not capping your
FPSand going on with the naturalFPSof your program - Is it possible to have unlimited
FPSand still control myFPSfor time stuff like waits? - If so, how?
ANSWER
Answered 2021-Jun-14 at 21:42You have to calculate the movement per frame depending on the frame rate.
pygame.time.Clock.tick returns the number of milliseconds since the last call. When you call it in the application loop, this is the number of milliseconds that have passed since the last frame.
When you call it without a parameter (framerate=0), the FPS are unlimited.
Define the distance in pixels that the player should move per second (move_per_second). Then compute the distance per frame in the application loop:

I need to merge these folders that have a TON of files in each directory. I would use folder.copy but that takes forever.
I have been using xcopy process to handle this for the most part but I have been getting errors from xcopy saying that there are duplicates when there are none. So I am trying to find a solid work around that is as fast or even faster then xcopy.
What I have tried before is:

if that is not fast enough, then I would think your next option would be trying with straight win32api

QUESTION
When reading, Spark have a mapping 1:1 to kafka partitions, so, with more partitions we can leverage more parellelism to our job.
But does it apply when Spark is writing in kafka ? Writing the same dataset in one topic with 4 partitions is more fast than writing in a topic with 1 partition ?
...ANSWER
Answered 2021-Jun-14 at 14:31Yes.
If your topic has 1 partition means it is in one broker. So, If you increase producer rate for the topic, then that broker becomes busy. But if you have multiple partitions, your Kafka cluster shared those partitions into different brokers and those production rate shared within multiple brokers. So, Writing the same dataset in one topic with 4 partitions is more fast than writing in a topic with 1 partition.
This not only production rate. In Kafka brokers, There is multiple processes like compactions, compressions, segmentations etc... So with number of messages, that work load becomes high. But with multiple partitions in multiple brokers, it will be distributed.
However, you don’t necessarily want to use more partitions than needed because increasing partition count simultaneously increases the number of open server files and leads to increased replication latency.
from kafka documentation
Distribution The partitions of the log are distributed over the servers in the Kafka cluster with each server handling data and requests for a share of the partitions. Each partition is replicated across a configurable number of servers for fault tolerance. Each partition has one server which acts as the "leader" and zero or more servers which act as "followers". The leader handles all read and write requests for the partition while the followers passively replicate the leader. If the leader fails, one of the followers will automatically become the new leader. Each server acts as a leader for some of its partitions and a follower for others so load is well balanced within the cluster.
QUESTION
My GUI is able to play videos automatically when selected in the QListWidget. However, instead of normal speed, the videos play very fast. I use 720p Mp4 videos as examples and are placed in a certain folder. I tried using cv2.CAP_PROP_FPS and cv2.CAP_PROP_BUFFERSIZE, but they are both not working. I am using pyqtSignal in the QThread and the convert_cv_qt function which I saw in other guides. How do I play the videos in normal speed / frame rate?
ANSWER
Answered 2021-Jun-14 at 10:44When you use VideoCapture with a file if you call "cap.read()" you will obtain the next frame on the video, regardless of its actual framerate. Hence, you should use a "msleep" every time you capture a frame:
