P Analysis of why UMAP is so fast
Hi, I recently spent some time to understand the core implementation of the UMAP algorithm from the point of view how it was implemented and why it's so fast (even though it's in python). I decided to decompose the algorithm into smaller steps in which I add some minor improvements to the code (one by one), so that at the end the final results are very similar to what I can get from the UMAP.
To my surprise, most of these changes were just tricks in the optimization code to run things faster or update less important things less often. Of course, my implementation does not reproduce the UMAP algorithm in 100% as it was done in the educational purposes.
I provided a detailed explanation in my project of what I had to add in each step to move towards UMAP like algorithm. Here is the project page: https://github.com/kmkolasinski/nano-umap
If you are a person like, who likes to optimize the code for performance you may find this interesting. Here is a demo what I was able to get:

TLDR: in UMAP they:
use ANN library to quickly find top k-NN,
use good initialization method which makes things more stable and algorithm requires

🚀 Feature Friday: PostgreSQL Connection Pools!
Welcome to this week's Django Feature Friday on PostgreSQL Connection Pools!
This small-but-mighty change lets you enable connection pooling with a single line in your settings. This reduces the overhead of accessing your database, leading to improved performance.
You can turn it on like this:
DATABASES = {
"default": {
"ENGINE": "django.db.backends.postgresql",
# ...
"OPTIONS": {
"pool": True,
},
},
}
If you want fine-grained control over your connection pools, you can also explicitly configure them by passing in a dictionary of settings:
DATABASES = {
"default": {
"ENGINE": "django.db.backends.postgresql",
# ...

I played a minute-long video in Windows Terminal
I recently worked on a project combining my love for terminal limits and video art. Here’s what I achieved: • Rendered a 1-minute-long (almost two) ASCII video in the terminal, without graphics libraries or external frameworks. • Used true 24-bit colors for each frame, offering deeper color representation in terminal-based projects. • Processed 432 million characters over 228 seconds, translating each frame’s pixels to colors. • Optimized performance with multi-processing, running on an integrated graphics card.
Specs:
• 30 FPS
• 160,000+ characters per frame
• 2,700 frames
• 3 pixels per character for better performance
For further optimization, I reduced the font size to 3 pixels and used background colors to handle brightness.
What my project does?
While not the most practical project, it’s an experiment I’m satisfied with it. No real use, but hey, it’s fun!
Target audience
This is more of a fun project so I can't say it has a specific target audience, but I could say that people that strangely feels good coding "useless" things might like it.
Comparison
Well it is not an ASCII player anymore to be precise, but what it does now is just display video in the terminal using basically pure ANSI, I

Game 987, Like 2048 but Fibonacci (Made in Python)
https://987.reflex.dev/
What My Project Does
From Adhami the author: I was wondering how 2048 would feel like if instead of powers of two, we can merge consequent fibonacci numbers. Turns out to be a rather interesting game that is fairly forgiving and grows very slowly. I found it difficult to come up with an overall strategy. I had a simple search algorithm that was able to achieve a score of exactly 66,666 (not joking). Getting a 987 block shouldn't be difficult.
You can take a look into the code here: https://github.com/adhami3310/987 (the simple search algorithm is inside the code as well)
Target Audience: Anyone
Comparison: Similar to 2048 but fib

PyPI now has attestation. Thanks I hate it.
Blog post: https://blog.pypi.org/posts/2024-11-14-pypi-now-supports-digital-attestations/
I'm angry that it got partially funded by the sovreign tech fund, when it's about "securing" uploads by giving the keys to huge USA companies. I think it's criminal they got public money for this.
I also don't think it adds any security whatsoever. It just moves the authentication from using credentials to PyPI to using credentials to github. They can be stolen in the exact same way.

Is django a good choice?
Hey guys,
I currently trying to find the best solution to implement for a client of mine.
What started as a simple HRM implementation now runs more towards some kind of lean ERP solution.
I need something that can handle a lot of employee information and turnover across multiple clients and contracts types to generate accurate and pretty much automatic timesheets and invoicing.
The company is pretty only generating pay and invoices, but these have to follow pretty complex business rules.
I also have to handle a few HR processes that include on-boarding and termination along with some kind of document and signature tracking
Nothing out of the ordinary, but I couldn't find a solution that could do that without heavy customization and license fees.
I am leaning toward erpnext/frappe, but the installation process is much more complex than what I envisioned. I am also thinking about building something myself with Django and bootstraps or react, but I do not have great coding skills so build on something that is pre-existing would be much more approachable for me.
Any suggestions? I am in dire need of help here.

Just Finished Studying Django Official Docs Tutorials
I am a BSc with Computer Science and Mathematics major, done with the academic year and going to 3/4 year of the degree. I am interested in backend engineering and want to be job ready by the time I graduate, which is why I am learning Django. My aimed stack as a student is just HTMX, Django and Postgres, nothing complicated.
I have 6 projects (sites) that I want to have been done with by the time I graduate:
* **Student Analytics App**
* **Residence Management System**
* **Football Analytics Platform**
* **Social Network**
* **Trading Journal**
* **Student Scheduling System**
I have about 3 months to study Django and math alternatingly. I believe I can get a decent studying of Django done by the time my next academic year commences and continue studying it whenever I get the chance during my academic year.
Anyways, enough with the blabbering, I just got done studying the Django tutorials from the official docs. I love the tutorials, especially as someone who always considered YouTube tutorials over official docs. This is the first documentation I actually read to learn and not to troubleshoot/fix a bug in my code. I think it is very well written!
I wanted to ask:

Automation question
Hey all,
I'm trying to automate a process at my work to improve my efficiency. For context, imagine I work at workplace A which has its own database of information that staff need to access. On top of this there's workplaces B and C also who have the same situation. However all 3 workplaces need to access each of the workplaces data (A, B and C) which is done via a website. On the website we have to click a link down the bottom corner of the page to "swap workplace". This opens a new page where we then select the workplace we want and click submit.
Is there anyway to automate this process of being able to just click a button and automatically be open up workplace A, without having to go into the menu.
There is no identifying feature for the workplace in the URL so I can't just bookmark different urls.
My initial thoughts were too have a process that targets particular ui elements and clicks them in series to do the job.
Thoughts?
Any help would be awesome!

Advice for Django Job
I recently started learning Django. I know how to make simple APIs with DRF. But I feel like there are too many abstractions like it makes it so easy to make a rest api. Anyways, Can some please tell me how to make it to full stack.... Is server side rendering and jinja templating all? Because on the other hand NextJS and React thing is very popular. I am studying AI/ML in parallel so what texh stach would be good for me?

I'm puzzled trying to update just 1 m2m object in a form
I have a form in a template where I want the ability to check a box and it shows an interest in a game for an official. There is a many-to-many relationship between games and officials.
In the template, the form presents only the user of all officials to either check or uncheck for a game.
If the user makes any change (checks or unchecks), they essentially uncheck all users associated with that game.
Please help point me in the right direction.
Here are relevant sections of code:
[models.py](http://models.py)
class Official(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
class Game(models.Model):
game_official_options = models.ManyToManyField(Official, blank=True, related_name='officials')
[view.py](http://view.py)
def GameDetail(request, slug):
game = officials_models.Game.objects.get(slug=slug)
if request.method == "POST":
form = officials_forms.GameInterestForm(request.user, , instance=game)
if form.is_valid():

D Neurips 2024 Hotel Roommate Search
The hotels around the venue for Neurips 2024 are pretty expensive, and I'm looking for a roommate to split the cost with (my university has a limit on the nightly hotel rate they are willing to reimburse). I currently have reserved a room for Tuesday-Sunday in the Century Plaza Hotel, which is 0.9 miles from the convention center. The nightly rate is $414. If anyone wants to split the cost of a room, please reach out! Also, it would be helpful if you could share this post with your research group or other attendees that you know.
If you are unsure about rooming with a complete stranger, you can get to know me a little bit through my personal website (https://mtcrawshaw.github.io/), which has links to my google scholar page, CV, etc. I do have a paper at the conference in the area of federated learning/distributed optimization.

D When you say "LLM," how many of you consider things like BERT as well?
I keep running into this argument, but for me when I hear "LLM" my assumption is decoder-only models that are in the billions of parameters. It seems like some people would include BERT-base in the LLM family, but I'm not sure if that's right? I suppose technically it is, but every time I hear someone say "how do I use a LLM for XYZ" they usually bring up LLaMA or Mistral or ChatGPT or the like.

Dispatchery: Type-aware, multi-arg function dispatch for complex and nested Python types
Links: [Github](https://github.com/bolaft/dispatchery/), [PyPI](https://pypi.org/project/dispatchery/)
**What it does:**
*dispatchery* is a lightweight Python package for function dispatching inspired by the standard *singledispatch* decorator, but with support for complex, nested, parameterized types, like for example *tuple[str, dict[str, int | float]]*.
**Comparison**:
Unlike *singledispatch*, *dispatchery* can dispatch based on:
- Generic parameterized types (e.g. *list[int]*)
- Nested types (e.g. *tuple[str, dict[str, int | float]]*)
- Union types (e.g. *int | str* or *Union[int, str]*)
- Multiple arg and kwarg values, not just the first one
**Target Audience:**
Python developers who don't like having a bunch of *if isinstance* checks everywhere in their code.
**Example :**
from dispatchery import dispatchery
@dispatchery
def my_func(value):
return "Standard stuff."
@my_func.register(list[str])
def _(value):
return "Strings!"
@my_func.register(list[int] | list[float])
def _(value):
return "Numbers!"
@my_func.register(str, int | float, option=str)
def _(value1, value2, option):
return "Two values and a kwarg!"

Django models reverse relations
Hi there! I was exploring Django ORM having Ruby on Rails background, and one thing really seems unclear.
How do you actually reverse relations in Django? For example, I have 2 models:
class User(models.Model):

class Address(models.Model):
user = models.OneToOneField(User, related_name='address')
class User < ApplicationRecord
has_one :address
end
class Address < ApplicationRecord
belongs_to :user

Finding a Django Learning Partner
HI All,
I am in a difficult position in my career with early layoffs and joining at time of recession. Due to all these I have derailed and have been extremely lazy to learn and lack the motivation. I am looking for a partner to learn Django together. Only motive is to share progess and keep each other motivated.
I am good with python and know only some basics of Django. I am a quick learner and academically strong. Preferable partner should be learning Django fully focused. I am a 2022 graduate (if that matters)
Mentors willing to mentor me through this rough phase are appreciated too.
