D Theory behind modern diffusion models

Hi everyone,

I recently attended some lectures at university regarding diffusion models. Those explained all the math behind the original DDPM (Denoiding Diffusion Probabilistic Model) in great detail (especially in the appendices), actually better than anything else I have found online. So it has been great for learning the basics behind diffusion models (slides are available in the link in the readme here if you are interesed: https://github.com/julioasotodv/ie-C4-466671-diffusion-models)

However, I am struggling to find resources with similar level of detail for modern approaches—such as flow matching/rectified flows, how the different ODE solvers for sampling work, etc. There are some, but everything that I have found is either quite outdated (like from 2023 or so) or very superficial—like for non-technical or scientific audiences.

Therefore, I am wondering: has anyone encountered a good compendium of theoretical eplanations beyond the basic diffusion model (besides the original papers)? The goal is to let my team deep dive into the actual papers should they desire, but giving 70% of what those deliver in one or more decent compilations.

I really believe that SEO is making any search a living nightmare nowadays. Either that or my googling skills are tanking for some reason.

Thank you all!

D Why aren't Stella embeddings more widely used despite topping the MTEB leaderboard?

https://huggingface.co/spaces/mteb/leaderboard

I've been looking at embedding models and noticed something interesting: Stella embeddings are crushing it on the MTEB leaderboard, outperforming OpenAI's models while being way smaller (1.5B/400M params) and apache 2.0. Makes hosting them relatively cheap.

For reference, Stella-400M scores 70.11 on MTEB vs OpenAI's text-embedding-3-large 64.59. The 1.5B version scores even higher at 71.19

Yet I rarely see them mentioned in production use cases or discussions. Has anyone here used Stella embeddings in production? What's been your experience with performance, inference speed, and reliability compared to OpenAI's offerings?

Just trying to understand if there's something I'm missing about why they haven't seen wider adoption despite the impressive benchmarks.

Would love to hear your thoughts and experiences!

django-fastdev 1.13 released

Django-fastdev is a collection of improvement to Django. The focus is on better error handling/messages.

New since last time I posted:

- Improved TemplateNotFound errors
- Adds a new monkey patch for Model.__repr__ to fix infinite recursion in error messages for DoesNotExist and MultipleObjectsReturned (the first is a fastdev bug and the second is a Django bug)
- Reintroduced invalid block check with fixes

Conda kernel not found in Visual Studio Code

I'm trying to get back into machine learning. I tried six months ago, but my operating system crashed and I had to reinstall it completely, which was a bit of a shame!

The software might have had some updates since then, which is probably why I'm having trouble. I'm trying to select a kernel with Visual Studio Code, but I'm unsure if I'm doing it right. I followed the method given by VSCode, but I'm still stuck on kernel selection.

I'm happy to say that installing the extensions and creating the Conda environment went well! However, when I select the kernel, I get this message:

Flask Assets does not detect changes to less files on save but rebuilds with changes.

Hi, my workflow would be such that flask-assets would detect any changes in my less files and automatically restart the flask server and rebuild the assets. Relatively easy frontend development.

I loaded up an older project and reinstalled dependencies to current versions and noticed this funtionaliy changing. While the static files do update on a restart of the development server, the server does not detect changes to less file. Any suggestions on what would be causing this? Running flask 3.1 and flask assets 2.1

Django templates vs React

Hi everyone, why would I use React over Django’s templating system if I have below 500k users for anything? I feel like using React is pretty overkill for most web applications even if it needs to be dynamic, unless it’s a really custom app that needs to be highly dynamic. I feel that if I really wanted some front end reactivity, I could use libraries like AlpineJS and snabbdom, and that should be enough?

FYI, I can be a big noob. Looking for what people experience and a difference in opinions and perspectives. I ask this question more to find out what others think because I feel like web development can quickly become overkill and overly complex for no reason. So I’m a proponent for keeping things simple. Please share your thoughts/experience! Would kindly appreciate it.

Best library for Magic Links

I've seen there are several libraries for this (django-magiclink, django-magic-link, django-sesame, django-magicauth...)

Which one do you recommend? Or which things I should take into account when choosing?

I'm a Django beginner and I'm pretty lost here.

I want to receive payments using Stripe (Stripe Checkout probably) and send a magic link to the buyers so they can access a protected URL in my Django app. I will have several products (several protected URLs).

I don't need super advanced security or complex features. Just something simple (for me and my users).

Thanks!

MVP deployed

It doesn't function yet, it's not mobile ready, It doesn't use a database yet, I don't fully understand what I just did... but I'm learning day by day and finally got my django work visible somewhere besides my local.

The app is meant to help people track their poor spending habits. Eventually, a user will be able to add items they want, or need to buy, to the post-it note. Then each day they enter amounts spent on things like fast food or alcohol (anything they want to spend less money on) in the day boxes, and when the total surpasses one of the goal items the user will get a notification stating "You could've bought item 1" etc.

*NOTE: WAY BETTER ON PC (can't grab the note on mobile yet)

YTSage is a modern YouTube downloader designed for simplicity and functionality. With a sleek PyQt6 interface, it allows users to:
- 🎥 Download videos in various qualities with automatic audio merging.
- 🎵 Extract audio in multiple formats.
- 📝 Fetch both manual and auto-generated subnoscripts.
- ℹ️ View detailed video metadata (e.g., views, upload date, duration).
- 🖼️ Preview video thumbnails before downloading.

---

Target Audience:
YTSage is ideal for:
- Casual users who want an easy-to-use video and audio downloader.
- Developers looking for a robust yt-dlp-based tool with a clean GUI.
- Educators and content creators who need subnoscripts or metadata for their projects.

---

Comparison with Existing Alternatives:
- vs yt-dlp: While yt-dlp is powerful, it operates through the command line. YTSage simplifies the process with an intuitive graphical interface.
- vs other GUI downloaders: Many alternatives lack modern design or features like subnoscript support and metadata display. YTSage bridges this gap with its PyQt6-powered interface and advanced functionality.

Web Scraping Social Media Profiles X, Instagram, Tiktok, Youtube

Hi everyone!

I’ve created a noscript for scraping public social media accounts for work purposes. I’ve wrapped it up, formatted it, and created a repository for anyone who wants to use it.

# What My Project Does
The main focus of this project is to scrape data from profiles and their posts. For example:
- In my job, I’ve automated it to run daily for our social media profiles, storing the data for later analysis.
- A firend of mine wanted to download all the thumbnails of a youtube channel.

# How it works
The noscript uses Playwright to intercept requests and clean up the data. It also includes a second part that converts images to Base64 encoding, which is useful when image URLs expire or cannot be displayed directly in an HTML img tag. For YouTube, it uses the API v3, as it's straightforward to obtain an API key.

I believe the noscript is easy to use, and you can quickly adapt it to suit your needs. Be sure to check out the README for more details!

# Target Audience
This tool is for anyone who needs to scrape social media data. The code is simple enough to copy, modify, and integrate into your project.

# Comparison
I haven’t extensively
