I've developed a library for send metrics to zabbix asynchronously

I have been using zabbix for monitoring a lot of metrics in my work, none of the most popular zabbix were capable of doing async tasks, so I've developed some simple package capable of doing this.

Tests, examples and how-tos can be found here: [https://github.com/gustavofbreunig/zabbix-sender-async](https://github.com/gustavofbreunig/zabbix-sender-async)

**What My Project Does**

Send zabbix sender messages using asyncio tasks.

**Target Audience**

SysAdmins who use Zabbix to monitor a large number of metrics.

**Comparison**

Instead of doing traditional way, using these abandoned library: [https://github.com/adubkov/py-zabbix](https://github.com/adubkov/py-zabbix)

from pyzabbix import ZabbixMetric, ZabbixSender

# Send metrics to zabbix trapper
packet = [
ZabbixMetric('hostname1', 'test[cpu_usage]', 2),
ZabbixMetric('hostname1', 'test[system_status]', "OK"),
ZabbixMetric('hostname1', 'test[disk_io]', '0.1'),
ZabbixMetric('hostname1', 'test[cpu_usage]', 20, 1411598020),
]

result = ZabbixSender(use_config=True).send(packet)

You can do this:

async def sendmetrics():
sender = AsyncSender('localhost', 10051)
metric = ItemData(host='hostname', key='test.metric.text', value='test package import')
result = await sender.send(metric)

Python doc problem


Each item in turn is assigned to the target list using the standard rules for assignments (see Assignment statements), and then the suite is executed.
This is from python doc.'Assignment statements' is underlined, Why there is no reaction after I click it? How could I get more explanation of Assignment
statements?

Reviewing Dataframe Changes? Looking for Your Preferred Methods!

After playing around with a dataframe—applying filters or other transformations—I'm curious about your methods for reviewing the changes.

In VS Code, the variable explorer is quite handy for a quick look at the modified dataframe. Alternatively, when working in a Jupyter notebook within VS Code, exporting the data to an Excel file provides a detailed view and allows for an easy deep dive into the results. What are your preferred practices for ensuring your data adjustments are precisely what you intended?

Feeling at a loss with all these transformer models from Hugging Face in NLP "Discussion"


"[Discussion\]"

Recently I've started to work on NLP projects, and currently working on this kaggle competition "essay scoring classification problem". I was looking at others codes, and decided on working with three technique- one with machine learning model, one with a huggingface transformer and one with facebook's fasttext (heard they are good at getting the outlier or infrequent synonymous words).

While fasttext has few documentation and code sources; on the contrary, I am feeling lost by seeing ALL these transformer pretrain models from huggingface for text classification!

Which model should I choose? At first my selection criteria was based on the autotokenization method provided by the those transformers. But now I've been thinking what other parameters should I look at (I am working with basic tokenization from NLTK for the time being). I mean let's just consider computer vision. If I want to develop a face recognition system, at first YOLO's version will be the typical approach, if I have very few samples of images few shot learning can be given a chance.

But what about text? I have nearly 17000 samples consisting of approximately 3,55,00,000 words in total to train. I was thinking of

Library for automatic Cython 3.0 code annotations generation.

Hi everybody,

over the last year I've been developing a library that adds some Cython 3.0 annotations to existing python code.

What My Project Does:

For example if it sees a for i in range(): in a function it recognizes i as an integer and adds a i = cython.declare(cython.int)line at the beginning of the function.

It actually uses the built-in ast module under the hood for parsing, I found it a super useful library!

Target Audience:

It is a side project I made mainly for fun. I don't know if it can be of interest to anybody, or if it could have some potential utility.

Comparison:

I did not find anything similar. There are a lot of very cool projects like mypyc for example, but nothing that does this tiny little code generation specific to Cython.

How do I add a new entry to my many to many related table in Django?

I have two models Course and Educators. Course has 3 fields course\_name, course\_educators and course\_past\_educators which link Educators to Courses by many to many. I want to write a function so that whenever a new entry is added to course\_educators that entry will be copied over to course\_past\_educators.

#models.py
#code for Educators model
class Educators(models.Model):
educator_name=models.CharField(max_length=20,default=None)
educator_img = models.ImageField(upload_to='educators_img',default=None)

#code for Courses model
class Course(models.Model):
course_name = models.CharField(max_length=100)
course_educators=models.ManyToManyField(Educators, related_name='current_educators', default=None, blank=True)
course_past_educators=models.ManyToManyField(Educators, related_name='past_educators', default=None, blank=True)

#This is the function I wrote so that entries into course_past_educators are automatically added when course_educators is added with another entry.

Advice for Migrating from Django 2.0 to Django 5.x

Hey everyone,

I'm looking for some guidance on migrating my Django project from version 2.0 to the latest, version 5.x. Currently, my project is running on Django 2.0 with Python 3.6, but I'm eager to leverage the advancements and security enhancements offered by Django 5.x while upgrading to Python 3.12.

My project is of moderate sized and relies on around 30-40 Python packages for various functionalities. Surprisingly, there are no tests written, which is something I plan to rectify as part of this migration process.

Also it's been a long time I have touched Django & Python, so I need to brush up on my skills as well.

In my initial attempts at migration, I encountered login issues and noticed that web sockets were terminating before sending data. These challenges are making the migration process trickier than expected.


Could you please share any learning resources, tutorials, or tips that could help me learn the ropes of Django 5.x and Python 3.12 efficiently? Whether it's online courses, documentation guides, or community forums, any suggestions would be immensely valuable.

I'd greatly appreciate any advice, tips, or resources you could share to help smooth out this migration process. Specifically,

Djangos AllAuth password leak?

I'm using django allauths library to handle my authentication on my site, i noticed a peculiarity though when I checked the logs. its seems thats the library is printing out the login request details like the example below:

<QueryDict: {'csrfmiddlewaretoken': ['<token>'], 'login': ['email'], 'password': ['password']}>

i dont have anything on my side printing out this intentionally so it must be from the library afaik, im concerned as this could cause a large problem for websites in production using this library.


i'm not entirely sure i can correct this so please let me know.


custom user uses AbstractUser

Login url is default AllAuth URL

Looking For a Solution to manage Repeating Tasks for Users in Flask Web App

Context:
I'm running a Flask-based SaaS web app (server A), featuring a page where users can send request to an endpoint on server by clicking "START", the endpoint on server will fetch data from external APIs. The JS on the page will send request to the endpoint repeatedly every 3 seconds.They can also halt this process by clicking "STOP".

Requirements:
I need a solution that allows the server to continuously fetch data from external APIs for users without requiring them to keep the browser or app open until they decide to stop the process manually or the server initiates the stop.

Current Solutions and Challenges:

1. Sequential User Loop: Initially, I implemented a loop through all active users who clicked "START" to send requests to external APIs. However, this method faces the challenge of users' requests not being synchronized. Each request takes approximately 3 seconds to process. Consequently, users who initiate the process later have to wait for the previous requests to finish. For instance, if there are 100 users, the 100th user would need to wait at least 300 seconds before their task begins processing.
2. Celery-Beat/Redis Approach: To mitigate the synchronization issue, I created an endpoint on server A,

Unused import changes Django SQL

I'm seeing a weird Django issue and I'm hoping someone here can point me in the right direction. One of my models has an unused import. If I remove that import, I start getting errors that a table cannot be truncated because of a foreign key (there is a foreign key relationship between the 2 tables). Restoring the "unused" import fixes the error.

Any ideas how to fix or debug this?
Thanks

HTMX - Pagination, issue when paginating search results.


Hello, I am new to HTMX, I am using it in a Django project, in which I have a ListView that has pagination. The pagination works well with HTMX, but I have a problem when the queryset is filtered by the query variable sent from the html. When pressing the Submit button, it correctly returns the filtered list, and I can see the correct number of pages, but when changing to the second page this filter is lost, that is, it returns the complete object\_list to me. Can someone help me understand what I am doing wrong?
