R reasoning models are indecisive parrots

R1 , o1, and gemini 2.0 flash were put to the test on 27 different puzzles.

the models still default to familiar solutions rather than adapting to new contexts - they even impose nonexistent constraints, waste tokens, and arrive at the wrong answer. Examples:

Example 1

Question: A group of four people needs to cross a bridge at night. The bridge is very old and rickety. They have only one torch, and because it's nighttime, the torch is necessary to cross the bridge. Each person walks at a different speed:A takes 1 minute to cross,B takes 2 minutes,C takes 5 minutes, andD takes 10 minutes.What is the fastest time they can all get across the bridge?

Answer: 10 minutes, the speed of the slowest person as they cross the bridge together.

DeekSeek-R1: "...First, the constraints: the bridge can only hold two people at a time, and the torch is needed each time someone crosses. So, if two people go over together, one has to come back with the torch."

Example 2

Question: Suppose you're on a game show,

Kindly give me an advice on seeking a job.

Hi,

I started learning coding on my own and worked as a freelancer developing static websites. Later, I picked up Python-Django and took a job as a Junior Software Developer on April 15, 2024.

On August 19, both of my parents were involved in a serious accident, and my father had to undergo multiple surgeries, with his last operation taking place on December 31. Since the company did not offer me a work-from-home option despite my repeated requests, they closed my file.

Now that I have fulfilled my responsibilities in taking care of my parents, I am actively looking for a job, but finding one has been challenging.

The skills I have developed include Python, Django Framework, REST APIs, SQL, MySQL, AWS, HTML, CSS, and Git.

Please provide me with advice on how to proceed.

Optimizing data storage in the database

Hi All!


My Django apps pulls data from an external API and stores it in the app database. The data changes over time (as it can be updated on the platform I am pulling from) but for various reasons let's assume that I have to retain my own "synced" copy.

What is the best practice to compare the data I got from the API to the one that I have saved? is there a package that helps do that optimally? I have written some code (quick and dirty) that does create or update, but I feel it is not very efficient or optimal.


Will appreciate any advice.

A really specific situation with a page redirecting to itself in another language.

My website is available in english and pt-br, for that, I'm using the django.template.context_processors.i18ndjango.

My settings look like this:

LANGUAGE_CODE = 'en-us'
LANGUAGES = [ ('en', 'English'), ('pt-br', 'Português'), ]
TIME_ZONE = 'America/Sao_Paulo'
USE_I18N = True
USE_TZ = True
LOCALE_PATHS = [BASE_DIR / 'locale']

Everything works correctly, but I need the option for the user to switch languages and stay on the same page.

What I implemented is this form:
<form action="{% url 'set_language' %}" method="post" class="sub-menu-content flow">

{% csrf_token %}

<fieldset onchange="this.form.submit()">

<label for="en-language-input">English</label>

<input type="radio" id="en-language-input" name="language" value="en" {% if LANGUAGE_CODE == 'en' %}checked{% endif %}>



<label for="pt-br-language-input">Português Brasileiro</label>

<input type="radio" id="pt-br-language-input" name="language" value="pt-br" {% if LANGUAGE_CODE == 'pt-br' %}checked{% endif %}>

</fieldset>

</form>

It also works fine, except when you access the website with an /en/ language prefix.
I tested it with brazilians and non-brazilians,

\- if you open the website without a language prefix, it will switch to default (en, or pt-br depending where you live) and the translation switch will work.
\- if you open the website with an /pt-br/ prefix, it will also work

I remember seeing mamba when it first came out and there was alot of hype around it because it was cheaper to compute than transformers and better performance

So why it disappeared like that ???

Tach - A Python tool to enforce dependencies

Source: https://github.com/gauge-sh/tach

Python allows you to import and use anything, anywhere. Over time, this results in modules that were intended to be separate getting tightly coupled together, and domain boundaries breaking down.

We experienced this first-hand at a unicorn startup, where the entire engineering team paused development for over a year in an attempt to split up tightly coupled packages into independent microservices. This ultimately failed, and resulted in the CTO getting fired.

This problem occurs because:

It's much easier to add to an existing package rather than create a new one
Junior devs have a limited understanding of the existing architecture
External pressure leading to shortcuts and overlooking best practices

Attempts we've seen to fix this problem always came up short. A patchwork of solutions would attempt to solve this from different angles, such as developer education, CODEOWNERs, standard guides, refactors, and more. However, none of these addressed the root cause.

# What My Project Does

With [Tach](https://github.com/gauge-sh/tach), you can:

1. Declare your modules ([`tach mod`](https://docs.gauge.sh/usage/commands#tach-mod))
2. Automatically declare dependencies ([`tach sync`](https://docs.gauge.sh/usage/commands#tach-sync))
3. Enforce those dependencies ([`tach check`](https://docs.gauge.sh/usage/commands#tach-check))
4. Visualize those dependencies ([`tach show`](https://docs.gauge.sh/usage/commands#tach-show) and [`tach report`](https://docs.gauge.sh/usage/commands#tach-report))

You can also enforce a [public interface](https://docs.gauge.sh/usage/interfaces) for each module, and [deprecate dependencies](https://docs.gauge.sh/usage/deprecate) over time.

Django Template LSP – For those not using PyCharm

For everyone not using PyCharm, I’ve built an LSP server for Django templates! After using it for a few months, I’m happy to release v1.0.0, and I think it works pretty well.

🔹 Autocomplete for {% load %}, {% static %}, {% url %}, custom tags/filters and context variables.
🔹 Go-to definition for templates, views, and context variables.
🔹 Hover docs for {% url %} and template tags/filters.
🔹 Works with Neovim, Helix, VS Code and others that support lsp's.

D Warning about Vultr Coupons

Heads up for anyone thinking about using Vultr with promotional credits—your experience might not be as smooth as expected.

I had $300 in promotional credits plus $5 I personally deposited (which I assumed was for identity verification), but I wasn’t able to use any of it.

First, they asked me to verify my profile, which I did. Then, out of nowhere, they demanded that I deposit another $50 just to access the funds I already had—effectively making my $300 in credits unusable. This requirement isn’t mentioned upfront, which is frustrating. If you're already committed to using Vultr, this might not be an issue, but if you just want to test the service, it feels weird.

To make things worse, you won’t necessarily be able to deploy your instances instantly. In many cases, you’ll need to open a support ticket and manually request access.

Their promotional credits and deposit policies are misleading, and once your money is in, you may not get it back. They don’t issue refunds. I couldn’t find any refund button on their website, and when I tried to request a refund through PayPal, they suspended my account immediately.

Corey Schafer's Django Blog Tutorial

Hey guys! I was just reaching out to see if anyone else has completed finishing this series. I'm looking to get some help because on video 13, right before deploying, I had issues setting up my aws S3. I ran a test script to see if sending a file locally would work and it worked. However, if I run my blog locally and update a profile picture, a new image would be added in my local media folder but not in S3. I made sure to set up my environment variables correctly and to set up my aws stuff according to the video. Anything helps! I also know this is very vague so please feel free to ask what i've tried so far. Thank you!

Which hosting for a simple application?

I'm looking for hosting for an amateur project developed with Python3 + Flask. It's a simple application that will generate almost no traffic for most of the year, but on specific dates, it will be used by up to a few hundred people to access a page with data updated via WebSocket.


So, I'm looking for a provider that offers scalability when needed. I've already used AWS, but it might be "too much" for my needs.

Are all inputs for "filter" method safe from sql injection?

Hi.
i'm making a simple online store app for learning purposes. For item properties, i've used a json field to store properties like size, color and .... . I've considered using database relations but i figured this would be simpler. the item properties are stored in db like this: {"size": "XL", "color": "red"}
I'm implementing a simple search functionality and since there are many properties, i'm wondering if it's safe to get property names from users.

was using json field a bad choice? what would a be good replacement?

this is my code for search view:

def search_items(request):
    q = request.GET.get('q')
    filters = request.GET.get('filters')
    items = Item.objects.filter(name__icontains=q)
    if filters:
        options = {}
        filters_list = json.loads(filters)
        for f in filters_list:
            options[f"properties__{f[0]}__icontains"] = f[1]
        items = items.filter(**options)

How Rust is quietly taking over the Python ecosystem

Been noticing an interesting trend lately - Rust is becoming the secret sauce behind many of Python's most innovative tools. As someone who works with Python daily, it's fascinating to see how the ecosystem is evolving.

Here's what's caught my attention:

* **Ruff**: This linter is absurdly fast compared to traditional Python linters. Why? It's written in Rust. We're talking 10-100x speedups here.
* **PyOxidizer**: A solid solution for creating standalone Python applications. Again, Rust. (unfortunately not maintained anymore)
* **Polars**: This DataFrame library is giving Pandas a run for its money in terms of performance. Guess what? Rust under the hood.
* **Maturin**: Making it dead simple to create Python extensions in Rust.

My team has written a blog post diving deeper into this trend, specifically looking at PyO3 (the framework that makes Python/Rust integration possible) and showing how to build your own high-performance Python extensions with Rust. If you wish, you can read it here: [https://www.blueshoe.io/blog/python-rust-pyo3/](https://www.blueshoe.io/blog/python-rust-pyo3/)

The really interesting part is that most Python developers don't even realize they're using Rust-powered tools. It's like Rust is becoming Python's performance co-pilot without much fanfare.

What are your thoughts on this trend? Have you tried building any Python extensions with Rust?

Flask limits with many users?

I developed a webapp in flask using jinja2 as frontend. It is now being hosted on a AWS EC2 server and the project is getting big in terms of users. Shall I start thinking about to change my backend technology or flask could still work? How many users could it support taking into consideration it is just about to do some simple query to my database?

How to link to images in a subfolder of the templates folder?

I'm working on rebuilding my small blog in Flask. I currently have pages organized in year and date folders. So, all the specifics (html and images) for 2025-02-04 would be in /2025/0204/ . I'm looking to do the same in the templates folder in Flask.

How do I link to the images in the sub-sub-folder in the html? From what I know url_for() only looks in static for images.

fastplotlib, a new GPU-accelerated fast and interactive plotting library that leverages WGPU

What My Project Does

Fastplotlib is a next-gen plotting library that utilizes Vulkan, DX12, or Metal via WGPU, so it is very fast! We built this library for rapid prototyping and large-scale exploratory scientific visualization. This makes fastplotlib a great library for designing and developing machine learning models, especially in the realm of computer vision. Fastplotlib works in jupyterlab, Qt, and glfw, and also has optional imgui integration.

GitHub repo: https://github.com/fastplotlib/fastplotlib

Target audience:

Scientific visualization and production use.

Comparison:

Uses WGPU which is the next gen graphics stack, unlike most gpu accelerated libs that use opengl. We've tried very hard to make it easy to use for interactive plotting.


Our recent talk and examples gallery are a great way to get started!
Talk on youtube: https://www.youtube.com/watch?v=nmi-X6eU7Wo
Examples gallery: https://fastplotlib.org/ver/dev/gallery/index.html

As an aside, fastplotlib is not related to matplotlib in any way, we describe this in our FAQ: https://fastplotlib.org/ver/dev/userguide/faq.html#how-does-fastplotlib-relate-to-matplotlib
