I wrote a tool for efficiently storing btrfs backups in S3. I'd really appreciate feedback!
What My Project Does
btrfs2s3 maintains a tree of incremental backups in cloud object storage (anything
with an S3-compatible API).
Each backup is just an archive produced by btrfs send [-p].
The root of the tree is a full backup. The other layers of the tree are incremental
backups.
The structure of the tree corresponds to a schedule.
Example: you want to keep 1 yearly, 3 monthly and 7 daily backups. It's the 4th day of
the month. The tree of incremental backups will look like this:
- Yearly backup (full)
- Monthly backup #3 (delta from yearly backup)
- Monthly backup #2 (delta from yearly backup)
- Daily backup #7 (delta from monthly backup #2)
- Daily backup #6 (delta from monthly backup #2)
- Daily backup #5 (delta from monthly backup #2)
- Monthly backup #1 (delta from yearly backup)
- Daily backup #4 (delta from monthly backup #1)
- Daily backup #3 (delta from monthly backup #1)
- Daily backup #2 (delta from monthly backup #1)
- Daily backup #1 (delta from monthly backup #1)
The daily backups will be short-lived and small.

Push notifications using pushover api
what my project does:
conveniently can be imported into existing python package and initialized with your own api key/token, sends text notification or image notification to where ever the pushover app exists. logs notifications sent per device or all devices. logs can be reviewed in local json file
Target Audience:
Anyone that has a raspberry pi or server they monitor can send push notifications instead of cluttering their email inbox more. if you have a raspberry pi set up with camera can send push notification if movement is detected
comparison:
I could not find anything else out there like this, so decided to create one

Guidance with a Django project front-end
I will be building a project for a client that involves developing an application to display data uploaded via Excel files. The application will include Google Maps integration, and data access will be role-based. Additionally, it will feature JWT-based authorization, along with login and logout functionality.
I have experience working with Django, primarily from building an user management system where I managed most of the functionality through the admin panel, which worked well for that project.
However, I’m currently struggling with the front-end design of my new project. Is it possible to use a theme for this? If so, how can I implement one? I would really appreciate any recommendations for tutorials that focus on modern design for Django applications.
While I’ve used admin panel themes before, I’m unfamiliar with applying themes to other parts of a Django project. Any guidance would be helpful!-

Whisper realtime hallucinations using Python...Open AI and .CPP models.
Does anyone have experience fixing hallucinations with Open AI Whisper and Whisper.cpp models when using realtime. All code is running via Python. Models tried from Tini to Large V3 both Open AI original models and .cpp verions for Metal.
Models are doing OK job with constant audio stream..however when audio hits silent (no one talking) or just mutes - then both Open AI and .cpp models seriously hallucinate by displaying "thank you, thank you, you, thank you....." and so on. none stop. Very annoing when you trying to put this to screen for monitoring.
Did some digging and so far no def answer on the fix (some tried and gave up)
Just checking if anyone has actually came across a fix. As specific parameters? not sure if for 3sec chunks VOD would be solution? or some kind of masking / filtering out?
Little lost on this, as: options: 1) Give up on whisper for this application 2) Is there actually a solution I am missing?
If anyone think they do have solution :) happy to pay for the correct answer if it fixes it!!
Thanks any way and all comments / suggestions are appreciated!

maestro, a command-line music player
[https://github.com/PrajwalVandana/maestro-cli](https://github.com/PrajwalVandana/maestro-cli)
**What My Project Does**
maestro is a command-line tool written in Python to play music in the terminal. The idea is to provide everything you could possibly think of for your music experience in one place.
**Target Audience**
Anyone who listens to music!
**Comparison**
Lots of stuff that the big-name services don't have, such as tagging (instead of playlists), a built-in audio visualizer, free listen-along feature (think Spotify Jams), lyric romanization, listen statistics, etc. See the list of features below/in the repo for more!
Unfortunately, you *do* have to download your music to use `maestro`.
**Features**:
* cross-platform (obviously including Linux, that's why I posted it here lol)!
* someone got it working on their Linux phone?? crazy stuff
* add songs from YouTube, YouTube Music, or Spotify!
* stream your music!
* read the technical breakdown here: [https://github.com/PrajwalVandana/maestro-cli/blob/master/data/maestro\_listen\_along.pdf](https://github.com/PrajwalVandana/maestro-cli/blob/master/data/maestro_listen_along.pdf)
* lyrics!
* romanize foreign-language lyrics
* translate lyrics!
* clips! (you can define and play clips for a song rather than the entire song)
* filter by tags! (replacing the traditional playlist design)
* listen statistics! (by year and overall, can be filtered by tag, artist, album, etc.)
* shuffle! (along with precise control over the behavior of shuffling when repeating)
* also "bounded shuffle", i.e. a

Are celery jobs reliable?
Hey everyone,
I have a product that currently uses fastapi+sqlite3 to implement the mvp. I have a scheduled task in fastapi to do a few python things every hour. Currently, it's been working great for me.
Looking to scale up my project and just wondering if celery is a reliable solution. I'll probably be using cookiecutter-django since it's built in and should workfor this project, but just wondering if celery is the right choice for this. It's important that it runs every hour.
Any advice would be appreciated,

DBOS-Transact: An Ultra-Lightweight Durable Execution Library
**What my project does**
Want to share our brand new Python library providing ultra-lightweight durable execution.
https://github.com/dbos-inc/dbos-transact-py
Durable execution means your program is resilient to any failure. If it is ever interrupted or crashes, all your workflows will automatically resume from the last completed step. If you want to see durable execution in action, check out this demo app:
https://demo-widget-store.cloud.dbos.dev/
Or if you’re like me and want to skip straight to the Python decorators in action, here’s the demo app’s backend – an online store with reliability and correctness in just 200 LOC:
https://github.com/dbos-inc/dbos-demo-apps/blob/main/python/widget-store/widget_store/main.py
No matter how many times you try to crash it, it always resumes from exactly where it left off! And yes, that button really does crash the app.
Under the hood, this works by storing your program's execution state (which workflows are currently executing and which steps they've completed) in a Postgres database. So all you need to use it is a Postgres database to connect to—there's no need for a "workflow server." This approach is also incredibly fast, for example 25x faster than AWS Step Functions.
Some more cool features include:
* Scheduled jobs—run your workflows exactly-once per time interval, no more need for cron.
* Exactly-once event processing—use workflows

D Why are most Federated Learning methods so dependent on hyperparameters?
I'm doing research in FL for some time now and went through a few subfields. Whenever I start a new project and do some benchmarking of existing methods, it always takes an eternity to get the methods to work on standard datasets like cifar10 that weren't used in the original papers. Currently I am using a premade benchmarking tool (fl-bench) and still struggle to get fedavg to converge on even slightly non-i.i.d. datasets on cifar10. This makes working in the field super frustrating imo. Did you have similar experiences or is there something fundamental that I missed all this time?

Reading Serial data and deploying it on FLASK
Hey everyone, hope you're all doing well. For the past two weeks, I've been stuck on my internship task, which involves reading data serially from an ESP32. The device is a machine maintenance system using a fluxgate sensor, DHT11, and a gyroscope. It serially sends data (x, y, z, total, temperature, and timestamp). My task is to read the data from the serial port and display it on a Flask web page using JavaScript. Every time I run the code in VS Code, I get an error saying "Port access denied." I'm not sure why this is happening, as no other IDE is running in parallel. I can provide the code if some one wants to figure out.

Can we talk about Numpy multi-core?
I hate to be the guy ragging on an open source library but numpy has a serious problem. It’s 2024, CPUs with >100 cores are not that unusual anymore and core counts will only grow. Numpy supports modern hardware poorly out of the box.
There are some functions Numpy delegates to BLAS libraries that efficiently use cores but large swaths of Numpy do not and it’s not apparent from the docs what does and doesn’t without running benchmarks or inspecting source.
Are there any architectural limitations to fixing Numpy multicore?
CUPY is fantastic well when you can use GPUs. PyTorch is smart about hardware on both CPU and GPU usage but geared toward machine learning and not quite the same use case as Numpy . Numba prange is dope for many things but I often find myself re-implementing standard Numpy functions. I might not be using g it correctly but DASK seems to want to perform memory copies and serialize everything. Numexpr is useful sometime but I sort of abhor feeding it my code as strings and it is missing many Numpy functions.
The dream would be something like PyTorch but geared toward general scientific computing. It would natively support CPU or

Free tool to convert Jupyter notebooks into PDF (new features!)
Converting a notebook using the LaTeX-based converter and hiding the code
Hi r/IPython,
Two years ago, I announced here a tool to convert Jupyter notebooks to PDF for free.
The tool has now converted more than 10,000 notebooks! So I figured I'd add some extra features.
The tool is available at https://convert.ploomber.io
# New features
I started by adding a LaTeX-based converter, which is great for generating academic reports (previously, it only had a browser-based converter).
Switching the configuration now changes the URL, this will make it easier to bookmark your favorite settings. e.g. this link will select the "hide code" option and select the LaTeX-based converter
# Ideas
A few ideas I have:
Allowing to generate a static URL to see the notebook
Add Quarto as a conversion backend
Quarto would open a lot of possibilities for advanced formatting, so I thought of adding templates for exporting PDFs (e.g. one column, two columns, add table of contents)
Add support for other formats such as HTML and DOCX
Let me know what other things might be useful!

Feature Friday: Django's Database-Generated Fields
Need DB-generated values in your Django models? Meet the new GeneratedField!
Define fields with values created by the database, not Django. This is powerful for computed columns & more.
DB-generated fields can be used for the following use cases:
- Computed columns
- Default values from DB functions
- Auto-updating timestamps
Here's a small sample code showing the usage of GeneratedField:
from django.db import models
from django.db.models import GeneratedField
class Product(models.Model):
name = models.CharField(max_length=100)
price = models.DecimalField(max_digits=10, decimal_places=2)
discounted_price = GeneratedField(
expression=models.F('price') * 0.9,
output_field=models.DecimalField(max_digits=10, decimal_places=2),
db_persist=True

pyrtls: rustls-based modern TLS for Python
What My Project Does
pyrtls is a new set of Python bindings for rustls, providing a secure, modern alternative to the venerable ssl module. I wanted to allow more people to benefit from the work we've done to build a better alternative to OpenSSL-backed TLS, and figured Python users might be interested.
https://github.com/djc/pyrtls
Target Audience
This is basically an MVP. While the underlying rustls project is mature, the bindings are fairly new and could contain bugs. I'd be happy to get feedback from people eager to try out something modern (and more secure).
Comparison
Unlike the ssl module (which dynamically links against OpenSSL), pyrtls is distributed as a set of statically compiled wheels for a whole bunch of platforms and Python versions. It is backed by Rust code, which is all memory-safe (except some core cryptography primitives), and avoids older protocol versions, insecure cipher suites, and risky protocol features. The API is intended to be similar enough to the ssl module that socket wrappers can act as a drop-in replacement.
