SSHaMan: A TUI for Managing SSH connections using Python & Textual

Good evening everyone. I just wrapped up my first open source project. It's functional at the moment, but definitely still alpha. It's a tool that you can use to manage SSH connections from inside the terminal.

I'm a pretty avid self-hoster with... a lot... of self-hosted services and keeping track of all my VMs is kind of painful with a .bashrc file. So I thought I'd feed two birds with one scone here and make an application to help that and also learn the Textual framework. This application presently doesn't do much that their demos don't do (I was able to repurpose their FileTree and just extend a few buttons), but I plan on digging in and learning Textual in subsequent versions to make this even more useful.

I would welcome any feedback! If anyone would like to contribute, I am absolutely open to PRs as well!

EDIT: D'oh! Forgot the link!

map-nl: Quickly create PC4 maps of the Netherlands

I just released a new small hobby project: map-nl

[Github](https://github.com/fpgmaas/map-nl)

It is a Python package that helps users quickly create maps of the Netherlands at the Postal Code 4 level. Nothing groundbreaking, but fun to develop and hopefully useful to some nonetheless. For example, creating a choropleth map of the Netherlands becomes as simple as:

import pandas as pd
from map_nl import ChoroplethMapNL

df = pd.read_csv("https://raw.githubusercontent.com/fpgmaas/map-nl/main/data/woz-pc4.csv")

m = ChoroplethMapNL(geojson_simplify_tolerance=0.0001).plot(
df,
pc4_column_name="pc4",
value_column_name="WOZ",
legend_name="Average WOZ Value"
)
m.save("map.html")

Curious for your thoughts, please let me know if you have any feedback!

Where do you get your images from?

I am building this flask web app and want to put in some images, but I don't know where from. To be specific: do I just put the URL of an image from online, do I download them and just use the local path or do I just do something else like make a public git-repo and use that URL. Any help is appreciated!

Why is ´print´ not recommended in linters?

I am writing a mini-program for basic payment calculation, and after the calculation the results are printed in the terminal. However, I get the following warnings from Ruff (the Python linter that I use):

src/pfexample/foodpayment.py:39:5: T201 print found
src/pfexample/foodpayment.py:51:5: T201 print found
src/pfexample/foodpayment.py:52:5: T201 print found
src/pfexample/foodpayment.py:54:5: T201 print found
src/pfexample/foodpayment.py:56:9: T201 print found

I know that I can turn off this check in the settings, BUT I don't why print is bad in the code. What would be the alternatives if not using print?

When should I start learning flask?

So basically I am a 12th grade student who have a sound knowledge of python basics, functions, file handling and exception handling. I am planning to move on to OOPs and making some projects after I finish my final examinations. But before I do that i have a doubt like what are the exact pre requisites I need to learn in python before moving to any python framework(like flask).

Will Pandas have streaming in Future??

As Pandas has switched to arrow backend from version 2.0, is there a possibility that we can see Lazy Evaluation or streaming in Pandas so that we'll be able to process datasets larger than memory on a machine as we have in Polars??

Use cases of Django

Hello guys. I have a little IT business, we create different web applications. I'm also a CTO in this firm, so I understand something in programming. We write frontend on Vue, backend on Asp.net/spring/fastapi. Also we use some clean architecture patterns. We use c#/java for big, complex applications and fastapi for e-commerce.
I discovered Django, and it's possibilities look interesting for short time to market, compared to other frameworks. What best use cases can Django offer in context of my organization? Share your experience please

How will you use the new Django 5.0 GeneratedField?

I'm pretty exciting by this new feature and I was wondering how I could benefit from it.

My first question: are properties still relevant?

For example, something like:

@property
def full_name(self) -> str:
    return f"{self.first_name} {self.last_name}"

could be easily replaced by a generated field. However, as it's not a CPU intensive task, I'm not sure I'd benefit from it.

Then I was thinking of annotations. In some cases, they can be a little painful to write, and I always have to remember if my queryset is contains the annotation or not. However, what if I replace annotation by a generated field, will it create an overhead, in a sense that it will compute stuff when I may not require it. Maybe the persist_db is the answer to this question?

I'd be glad to know how are you going to use this welcome feature.

Flask for Video Site

I have this collection of short mp4 video clips (ranging from 30s-2min) coupled with images of explanations of the videos.

The files all organised pretty well, using a letter for categories and an integer for the video number (A1-A52, B1-B40 etc) then the corresponding images use the same format with .png instead of mp4.

Obviously S3 is the place for these.

I've been working on a flask app that runs locally it consists of a index home page with menus/submenus to select the video category which takes you to a new page and displays the videos in a menu which you can hover to display a gif of the video and click to expand the video and play it.

I'm wondering what the best way to implement this using Flask:

* On the front-end side too, is there any tools that make developing this type of site easier? I'm bashing away at CSS and JS to glue the video player and display a button to show the explanation of the clip.

Is **Flask** the best tool to use for this HTML/CSS/JS site or should I be using something else?

I would also like to implement a 'test' scenario that would run through 20 clips and have you
