ArgMan — Lightweight CLI argument manager

Hey everyone — I built ArgMan because I wanted something lighter than argparse with easier customization of error/help messages.

What My Project Does
- Lightweight command-line argument parser for small scripts and utilities.
- Supports positional and optional args, short & long aliases (e.g., -v / --verbose).
- Customizable error and help messages, plus type conversion and validation hooks.
- Includes a comprehensive unit test suite.

Target Audience
- Developers writing small to medium CLI tools who want less overhead than argparse or click.
- Projects that need simple, customizable parsing and error/help formatting rather than a full-featured framework.
- Intended for production use in lightweight utilities and scripts (not a full replacement for complex CLI apps).

Comparison
- vs argparse: Far smaller, simpler API and easier to customize error/help text; fewer built-in features.
- vs click / typer: Less opinionated and lighter weight — no dependency on decorators/context; fewer higher-level features (no command groups, automatic prompting).
- Use ArgMan when you need minimal footprint and custom messaging; use click/typer for complex multi-command CLIs.

Install

pip install argman

D Why TPUs are not as famous as GPUs

I have been doing some research and I found out that TPUs are much cheaper than GPUs and apparently they are made for machine learning tasks, so why are google and TPUs not having the same hype as GPUs and NVIDIA.

Built pandas-smartcols: painless pandas column manipulation helper

**What My Project Does**

A lightweight toolkit that provides consistent, validated helpers for manipulating DataFrame column order:

* Move columns (`move_after`, `move_before`, `move_to_front`, `move_to_end`)
* Swap columns
* Bulk operations (move multiple columns at once)
* Programmatic sorting of columns (by correlation, variance, mean, NaN-ratio, custom key)
* Column grouping utilities (by dtype, regex, metadata mapping, custom logic)
* Functions to save/restore column order

The goal is to remove boilerplate around column list manipulation while staying fully pandas-native.

**Target Audience**

* Data analysts and data engineers who frequently reshape and reorder wide DataFrames.
* Users who want predictable, reusable column-order utilities rather than writing the same reindex patterns repeatedly.
* Suitable for production workflows; it’s lightweight, dependency-minimal, and does not alter pandas objects beyond column order.

**Comparison**

**vs pure pandas**:
You can already reorder columns by manually manipulating `df.columns`. This library wraps those patterns with input validation, bulk operations, and a unified API. It reduces repeated list-editing code but does not replace any pandas features.

**vs polars**:
Polars uses expressions and doesn’t emphasize column-order manipulation the same way; this library focuses specifically on pandas workflows where column order often matters for reports, exports, and manual inspection.

Use `pandas-smartcols` when you want clean, reusable column-order utilities. For simple one-offs, vanilla pandas is enough.


**Install**

PyCalc Pro v2.0.2 - A Math and Physics Engine With Optional GPU Acceleration For AI Integration

PyCalc Pro has now evolved from just being your average CLI-Python Calculator to a fast and safe engine for AI integration. This engine supports both mathematical and physics functions combining NumPy, Numba, SciPy, CuPy, and a C++ core for maximum performance.

Why it’s different:

Automatically chooses the fastest execution mode:
GPU via CuPy if available
C++ fallback if GPU is unavailable
NumPy/Numba fallback if neither is available
Benchmarks show that in some situations it can even outperform PyTorch.

Target Audience:

Python developers, AI/ML researchers, and anyone needing a high-performance math/physics engine.

Installation:
CPU-only version:

pip install pycalc-pro
pycalc

Optional GPU acceleration (requires CUDA and CuPy):

pip install pycalc-progpu
pycalc

Links:

GitHub: [https://github.com/lw-xiong/pycalc-pro](https://github.com/lw-xiong/pycalc-pro)
PyPI: https://pypi.org/project/pycalc-pro/2.0.2/

Feedback, suggestions, and contributions are welcome. I’d love to hear what the community thinks and how PyCalc Pro can be improved!

OpenPorts — Tiny Python package to instantly list open ports

# 🔎 What My Project Does

OpenPorts is a tiny, no-fuss Python library + CLI that tells you which TCP ports are open on a target machine — local or remote — in one line of Python or a single command in the terminal.
Think: netstat \+ a clean Python API, without the bloat.

Quick demo:

pip install openports
openports




# 🎯 Target Audience

Developers debugging services locally or in containers
DevOps engineers who want quick checks in CI or deployment scripts
Students / Learners exploring sockets and networking in Python
Self-hosters who want an easy way to audit services on their machine

>

# ⚖️ Comparison — Why use OpenPorts?

Not Nmap — Nmap = powerful network scanner. OpenPorts = tiny, script-first port visibility.
Not netstat — netstat shows sockets but isn’t cleanly scriptable from Python. OpenPorts = programmatic and human-readable output (JSON-ready).
Benefits:
Pure Python, zero heavy deps
Cross-platform: Windows / macOS / Linux
Designed to be embedded in scripts, CI, notebooks, or quick terminal checks

# ✨ Highlights & Features

`pip install` and go — no complex setup
Returns clean, parseable results (easy

I wrote up a Python app and GUI for my mini thermal printer

Hey everyone, it's Mel :) Long time reader, first time poster (I think)

I bought a mini thermal printer a few weeks back after spotting it at my local Walmart. I was hoping to use it out of the box with my PC to print shopping lists, to-do lists, notes and whatnot - no luck! So my friends and I got together and reverse-engineered the comms between the printer and our smartphones, wrote Python code to connect to and print from our PCs, and I made a GUI for the whole thing.

* **What My Project Does:** Lets computers connect to the CPT500 series of thermal printers by Core Innovation Products, and print text and images to the printer from the comfort of your desktop computer!
* **Target Audience:** Just a personal project for now, but I'm thinking of going back into the code when I have more time to really polish it and make it available more widely.
* **Comparison:** I couldn't really find anything that directly compares. There is a project out there that works for the same printer, but it's meant to be hosted on online server instances (mine is local). Other similar programs don't work for that printer, either.

P RLHF (SFT, RM, PPO) with GPT-2 in Notebooks

Hi all, I implemented Reinforcement Learning from Human Feedback (RLHF) including Supervised Fine-Tuning (SFT), Reward Modeling (RM), and Proximal Policy Optimization (PPO) step-by-step in three notebooks.

I used these steps to train a GPT-2 model on Stanford Sentiment Treebank v2 (SST2), a dataset of movie reviews. After the SFT step, GPT-2 model learns to generate sentences that look like movie reviews. Next, I build a reward model from another instance of GPT-2 model with a reward head attached on top and train it to predict the sentiment associated with a movie review. Finally, in the PPO step, I further train the SFT model and use the reward from the reward model to encourage the SFT model to generate only the movie reviews with positive sentiment.

All the Jupyter notebooks are available on GitHub: https://github.com/ash80/RLHF\_in\_notebooks

For those curious, I also created a video walkthrough explaining each step of the implementation in detail on YouTube here: https://www.youtube.com/watch?v=K1UBOodkqEk

What fronted technology is most used with Django?

Context. Most of my side projects only required HTML and CSS. There has been the need for a bit of JavaScript, but nothing complex. With my latest project though I thought why not try something new.

Goal. Identify the most used frontend framework by the community outside of HTML and CSS, e.g. React, Vue, etc.

Rules :-
1. Search existing comments to see if your frontend framework of choice has already been added.
2. If it has already been added, up vote the comment, optionally adding any additional comments of yours as a sub comment to it.
3. Else, add a comment mentioning your frontend framework of choice, along with any additional comments you may have.

Djang with oauth2provider and custom GPT

Hi All

I need some help because I failed to set correctly my system.

I'm trying to configure a custom GPT with Oauth2 auth for the api calling by the custom GPT.

OAuth auth and api are provided by Django. For Oauth part I installed the oauth2\provider module in Django.

In Django:

I set a new application in admin/Django outh toolkit/applications with: client id, call back uri, client type: public, Authorization grant type:  Authorization code, client secret and Algorithm: No OIDC support

In custom GPT:

Without setting OAuth for the tools, the LLM is able to work and call the api to extract the data. But with Oauth enables I set client id, secret client, auth uri, token uri and by default pos request.

During testing the tools.

First I identified the id in url of custom GPT is not the same the id given in the call back uri by OpenAI. Is it normal ?

LLM identify correctly the tools and display me a button to connect to my website. Once connected I am redirected to OpenAI but in a new tchat (not the tchat when I was speaking) and this new tchat is not the custom tchat. I lost all history.

From django logs I can see call only
