poll | poll is an efficient char device access package for Go

maybe you guys here can help. i’m trying to get a token in a script on a website with python beautiful soup but i’m stuck at one part. the request i make is

So I created a poll model in my Django app. I'm going thorugh the polling app tutorial posted on the Django website, however, I'm using a remote MySQL database rather than a SQLite database.

I am querying a database for an item using R2DBC and Spring Integration. I want to extend the transaction boundary a bit to include a handler - if the handler fails I want to roll back the database operation. But I'm having difficulty even establishing transactionality explicitly in my integration flow. The flow is defined as

I have a Spring Boot app with a Kafka Listener implementing the BatchAcknowledgingMessageListener interface. When I receive what should be a single message from the topic, it's actually one message for each line in the original message, and I can't cast the message to a ConsumerRecord.

The code producing the record looks like this:

The Question

How do I best execute memory-intensive pipelines in Apache Beam?

Background

I've written a pipeline that takes the Naemura Bird dataset and converts the images and annotations to TF Records with TF Examples of the required format for the TF object detection API.

I tested the pipeline using DirectRunner with a small subset of images (4 or 5) and it worked fine.

The Problem

When running the pipeline with a bigger data set (day 1 of 3, ~21GB) it crashes after a while with a non-descriptive SIGKILL. I do see a memory peak before the crash and assume that the process is killed because of a too high memory load.

I ran the pipeline through strace. These are the last lines in the trace:

Hello we are trying to implment a Chat feature in our already working applicaiton which is a MERN stack app, we opted to use socket.io because its fairly easy to set up and use,we managed to get it working locally but when we deployed on our dev server the chat wasn't working , we followed this socket.io document to try and solve the problem which served us well when we had the CORS problem locally , https://socket.io/docs/v3/handling-cors/ this is the server side code used :

I know this question has been asked many times, but I still can't figure out what to do (more below).

I'm trying to spawn a new thread using std::thread::spawn and then run an async loop inside of it.

The async function I want to run:

Is there any better or simpler solution for this task:

"A matrix of dimensions MxN is given, filled with the numbers 0 and 1. The field on which the number 0 is written represents land, and the field on which it is written number 1 represents water. Write a function largestLake(int [] [] map) which calculates the size of the largest water surface in the matrix map. The size of a water surface is the number of fields of value 1 that that water surface contains. Two water cells are considered connected if they are adjacent horizontally, vertically or diagonally." ?

Example:
Input:
4 5 //MxN
0 0 1 1 0
1 0 1 1 0
0 1 0 0 0
0 0 0 1 1
Output:
6

I tried to find it with BFS algorithm, but it ended up with too many loops. It says in the task that "The best solution has complexity O (M * N)."

I loaded matrix in main and here is my function:

I'm doing a project where I need to monitor several hall sensors for a position encoding. The logic is pretty simple, but the digital signal is fast: it may have up to 350 position changes per second.

I was hoping I could simply write a hall sensor monitor program watching the GPIOs but it appears that these programs consume quite a bit of CPU if I monitor at the necessary frequency. I had hoped suspending the CPU between every poll would help, but it doesn't seem to make much difference.

Here's the polling loop from what I'm currently doing. It "works", but the CPU usage is far too high. I'm running this on a process that shares the "position" variable with other processes on a memory-mapped file.
