Naruto Hands Seals Detection (Python project)

I recently used Python to train an AI model to recognize Naruto Hands Seals. The code and model run on your computer and each time you do a hand seal in front of the webcam, it predicts what kind of seal you did and draw the result on the screen. If you want to see a detailed explanation and step-by-step tutorial on how I develop this project, you can watch it here.

D which universities and research centers are focusing on adversarial machine learning (especially in Germany) ?

Hey people, I'm curious about where core adversarial learning research is going on. Looking at the publications, I do see several papers from various organizations but rarely do I see an organization advertise that they are focusing on adversarial learning as a field. Especially so for the universities and institutes in Germany.

Threading/concurrency and flask

I am trying to make a flask app that does some processing with an LLM in the background. My naive approach was to check the database every second for unprocessed entries and then process them one by one. I did this using Python's threading library. It seems this doesn't actually work when using a real server like gunicorn.

From what I have seen the proper way to do this is using Celery. Celery though seems to work using RabbitMQ, which I have no idea about. The examples seem to be built around redis, wheras my site is built around SQLAlchemy (currently with SQLite for testing but this could change). I don't really get why work queues are necessary. Is there a better way of doing this or do I need to bite the bullet and learn celery?

SciPy 1.14 released

SciPy just released version 1.14: https://github.com/scipy/scipy/releases/tag/v1.14.0

### SciPy 1.14.0 Release Notes

SciPy 1.14.0 is the culmination of 3 months of hard work. It contains
many new features, numerous bug-fixes, improved test coverage and better
documentation. There have been a number of deprecations and API changes
in this release, which are documented below. All users are encouraged to
upgrade to this release, as there are a large number of bug-fixes and
optimizations. Before upgrading, we recommend that users check that
their own code does not use deprecated SciPy functionality (to do so,
run your code with python -Wd and check for DeprecationWarning s).
Our development attention will now shift to bug-fix releases on the
1.14.x branch, and on adding new features on the main branch.

This release requires Python 3.10+ and NumPy 1.23.5 or greater.

For running on PyPy, PyPy3 6.0+ is required.

### Highlights of this release

- SciPy now supports the new Accelerate library introduced in macOS 13.3, and
has wheels built against Accelerate for macOS >=14 resulting in significant
performance improvements for many linear algebra operations.
- A new method, cobyqa, has been added to scipy.optimize.minimize - this
is an interface for COBYQA (Constrained Optimization BY Quadratic
Approximations), a derivative-free optimization solver, designed to
supersede COBYLA, developed by the Department of Applied Mathematics, The
Hong Kong Polytechnic University.
- scipy.sparse.linalg.spsolve_triangular is

What is the best way to catch errors in settings or other places before they crash Gunicorn?

what is the best way to catch errors in settings or other places before they crash Gunicorn?

for example I'm trying to use envparse for getting .env settings, but Django throws an exception and it doesn't get logged.

is there a way to display detailed debug errors like Symfony does in debug mode?

It's been really frustrating coming from the PHP web dev side - setup and debugging is much harder...
But Python is better for the project I'm working on.

Any suggestions for unversal exception catching so I don't have Gunicorn crashing issues with no log output?

scamming the scammers with python

Source code: https://github.com/IdanHajbeko/revenge\_on\_scammers/

What my Project Does

This Python script sends numerous requests to scam websites using fake but valid credit card information. Each request incurs a small fee for the scammer's payment processor, making their scams costly. Additionally, it floods their login pages with fake usernames and passwords, making it harder for them to sift through and find real credentials.

Target Audience
This script is intended for people who have basic knowledge of Python(or advanced) and want to take down phishing scams.

R I finetuned GPT-2 and BERT 135,000 times to see if it's fair to pretrain on unlabeled text from the test set

TL;DR: seems fair.

Everyone knows that training on labeled test data is a big no-no if you wanna use that data for evaluation.

But if you pretrain on unlabeled test data, can you still use that data during evaluation?

Let's run an experiment on 25 text classification datasets, two LMs whose pretraining data we're pretty sure are not already contaminated, and across a few settings for the number of training and test observations.

For each dataset, the experiment sanity checks that pretraining on unlabeled text (independent of the test set) helps, i.e., that there's an effect to detect. Call this the pretraining boost. Next, the experiment evaluates the bias from pretraining on unlabeled text from the test set instead of unlabeled independent text. Call this the evaluation bias.

# Results

​

m=50 is based on the Real-world Annotated Few-shot Tasks \(RAFT\) benchmark \(https:\/\/arxiv.org\/abs\/2109.14076\), which also contains the inspiration for this question: “For each task, we release a public training set with 50 examples and a larger unlabeled test set. We encourage unsupervised pre-training on the unlabelled examples…”. The distributions above are those of marginal effects: averaged across 2 LM types, the 25 classification tasks, and their subsamples.

What’s so bad about hosting static HTML with Django?

I've seen people online citing security concerns, how exactly is it insecure vs a NGINX server?


Let me explain my position further:

I usually just spin up a Dockerized Django + Django Ninja API and consume the API with a separate, Dockerized React/Vue static frontend. Now that's two Docker containers in the limited space of my RPi's SD card.

I then discovered that, through some url patterns and some custom template view, I could just export the React/Vue as static HTML as usual, point Django to that path and have Django serve the "index.html" at Django's "/". Now I only need to deploy one Docker container, and I don't need two repos for one app. What's the catch here?

My simple tech stack for building apps (in 2024)

After meeting u/neogener today, I realised that some people might find it helpful to understand what a simple, robust, production tech stack looks like - particularly for a team of 1-5 people.

So here's my simple tech stack for building software in 2024 🎨

(Hand drawn by me 🙂)

* = things I don't use at the start. Most of these asterisked tools are optimisations, which I only need in certain situations.

As an example app, my product (https://photondesigner.com) uses this stack.

TLDR: you don't need many of the technologies that people say you need.

How to start and stop script from django admin panel

I am continuously scrapping some website so for that website i am making bunch of accounts. I am storing these info into below model

class BotAccount(AppBaseModel):
username = models.CharField(maxlength=20)
password = models.CharField(maxlength=100)
deviceid = models.CharField(maxlength=100)
active = models.BooleanField(default=False)

if active is true then that particular bot will automatically login and start scrapping into websites (scrapping script is ready). Its a while condition that goes on forever until BotAccount.objects.first().acive == False

So from admin panel if i uncheck this bot automatically stops. and if checked then bot start working

How do i do this in Django so that whole thing will run in background

N ESM3: Simulating 500 million years of evolution with a language model

Blog post: https://www.evolutionaryscale.ai/blog/esm3-release

Pre-print (pending approval): https://evolutionaryscale-public.s3.us-east-2.amazonaws.com/research/esm3.pdf

Abstract:

> More than three billion years of evolution have
produced an image of biology encoded into the
space of natural proteins. Here we show that language models trained on tokens generated by evolution can act as evolutionary simulators to generate functional proteins that are far away from
known proteins. We present ESM3, a frontier
multimodal generative language model that reasons over the sequence, structure, and function
of proteins. ESM3 can follow complex prompts
combining its modalities and is highly responsive
to biological alignment. We have prompted ESM3
to generate fluorescent proteins with a chain of
thought. Among the generations that we synthesized, we found a bright fluorescent protein at far
distance (58% identity) from known fluorescent
proteins. Similarly distant natural fluorescent proteins are separated by over five hundred million
years of evolution

The first huge release by EvolutionaryScale after spinning off Meta.

Weights and code are released, but with big caveats
