Deep dive into Python on a plane
Keep meaning to learn how to use Python but never found the time. I am due to have a long flight in a few days and my plan is to deep dive into it.
Any resources that I should download in advance?
I have Youtube video so send me on any recommends.
Already have "How to automate the boring stuff" , "pythonlearn" and "thinkpython2"
Wish me luck :)

D Why does training LLMs suck so much?
I work in hardware acceleration and have been slowly trying to move my focus into LLM/GenAI acceleration, but training LLMs literally sucks so much... Even just 100M parameter ones takes forever on 4 A6000 Adas, and while I don't spend idle time watching these, it gets so frustrating having to retrain realizing the LR is too high or some other small issue preventing convergence or general causal language understanding...
I know the more you do something, the better you get at it, but as a GRA by myself with an idea I want to implement, I truly feel that the overhead to train even a small LM is far from worth the time and care you have to put in
It just sucks because deadlines are always coming, and once you're done with pretraining, you still have to fine-tune and likely do some kind of outlier-aware quantization or even train LoRA adapters for higher accuracy
I really hope to never do pretraining again, but needing a model that abides to your specific size constraints to fit into (for example) your NPU's scratchpad RAM means I'm always stuck pretraining
Hopefully in the future, I can have undergrads do my pretraining for me, but for

ModuleNotFoundError (noob tutorial for DO droplet)
I'm just learning Linux and this is my first time setting up a server. I've got a DigitalOcean droplet and installed Ubuntu 24.04 (LTS) x64. Got SSH and firewall up and running and added a domain. So it was time to get Flask installed and move my site over from the DO App Platform.
Step 1
I'm following this tutorial (from 2013!) on DO's site: How To Deploy a Flask Application on an Ubuntu VPS. I'm also following along with this YouTube that's a bit more recent that follows DO's tutorial.
Step 2
Everything was fine until I got to sudo pip3 install virtualenv.
I got error: externally-managed-environment. After a bunch of googling and troubleshooting, I used sudo pip3 install virtualenv --break-system-packages to install it. And it installed.
Step 3
Next steps sudo virtualenv venv followed by source venv/bin/activate went fine. But then...
Step 4 (venv) sudo pip3 install Flask resulted in:

Arch Gateway - an open source intelligent gateway for AI agents - focus on business logic of agents
# What My Project Does
Arch is an intelligent Layer 7 gateway (proxy) designed to protect, observe, and personalize AI agents with your APIs. The project was born out of the belief that: Prompts are nuanced and opaque user requests, which require the same capabilities as traditional HTTP requests including secure handling, intelligent routing, robust observability, and integration with backend (API) systems for personalization - all outside business logic.
Check out the project here: https://github.com/katanemo/archgw Ask me anything.
# Target Audience
Meant to help developers building AI Agents in production with safety, observablity and personalization features needed for differentiation. Focus on the stuff that matters, not the crufty work to get agents into production.
# Comparison
Compared to NGINX, HAProxy, Envoy - Arch Gateway was designed for prompts. Engineered with purpose-built small LLMs, Arch handles the critical but undifferentiated tasks related to the handling and processing of prompts, including detecting and rejecting jailbreak attempts, intelligently calling "backend" APIs to fulfill the user's request represented in a prompt, routing to and offering disaster recovery between upstream LLMs, and managing the observability of prompts and LLM API calls - outside application code so that you can focus on what matters most
Compared to other proxies like Protkey,

Python users, how did you move on from basics to more complex coding?
I am currently in college studying A level Computer science. We are currently taught C#, however I am still more interested in Python coding.
Because they won't teach us Python anymore, I don't really have a reliable website to build on my coding skills. The problem I am having is that I can do all the 'basics' that they teach you to do, but I cannot find a way to take the next step into preparation for something more practical.
Has anyone got any youtuber recommendations or websites to use because I have been searching and cannot fit something that is matching with my current level as it is all either too easy or too complex.
(I would also like more experience in Python as I aspire to do technology related degrees in the future)
Thank you ! :)

Learning Django before a job interview
A company just called me to do a job interview and I was told they work with Django.
I've already worked with Fastapi and Flask and everything I know from Django is what I did long time ago in an online course. They are already aware that I don't know but they wanted to have an interview anyway.
My plan is the following:
In one week I will try to make something in Django for them and show it, just to make a good impression, like someone who is interested in learning.
So I was thinking about something like using a third api (spotify, for example) inside django where I can throw some artist ids and get the information back through Django. Like an API working inside of the framework.
Do you have some tips?

Flowkeeper -- a PySide6 (Python + Qt6) application
Greetings! Meet [Flowkeeper](https://flowkeeper.org/), a cross-platform desktop Pomodoro timer, which took me about a year to reach its current state. It is implemented in Python and relies on Qt6 for its UI. It supports recent macOS, Windows 10 and 11, and any mainstream Linux released within a couple of years, e.g. Ubuntu 22.04.
Feel free to reuse parts of it, or ask me any questions about how things are implemented.
# What My Project Does
It allows you plan your work for the day, and then execute it using Pomodoro Technique.
# Target Audience
Power users -- mainly creative professionals and students. Flowkeeper can be used in production and enterprise environments.
# Comparison
Compared to a typical Pomodoro timer, Flowkeeper:
* Implements Pomodoro Technique exactly as described in the [original book](https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://www.amherst.edu/system/files/media/Pomodoro%252520Guide_0.pdf&ved=2ahUKEwjNsqig_eWKAxW7U6QEHZQMA-8QFnoECAsQAQ&usg=AOvVaw20GKwRpyxshlCpBzcw7-40),
* Supports a wider range of desktop operating systems, including diverse Linux environments,
* Is more lightweight and performant (it's not based on Electron, and I routinely test it on a Core 2 Duo machine),
* Has portable versions and does not require admin rights to install,
* Is optimized for power users (keyboard shortcuts and rich set of settings),
* Does NOT have a paid version,
* Does NOT have a mobile version,
* Does NOT synchronize data across devices,
* Is NOT

Python in DevOps: My Favorite Tools
Hey! 👋
I rely on Python to do a lot of Ops / DevOps-type automation: automate workflows, create dashboards, manage infrastructure, and build helpful tools. Over time, I’ve found some Python-based approaches that make these tasks much easier and more efficient. Here’s what I use:
Custom dashboards with Flask and Prometheus Client
Automating workflows Schedule, then RQ, then finally Airflow
Network analysis with Scapy
Click / Typer / Rich for CLI (Starting with Click, but always moving past it at some point)
And, of course, a bunch more.
I made a list here:
https://www.pulumi.com/blog/python-for-devops/
Then, for fun, I tried to use Python for everything in a single service - using dagger for the container and pulumi for the Infra. ( I work for pulumi bc I'm a big fan of being able to use Python this way :) )

I built a "CodePen for Django Templates"
Hi all,
I have built a online Django Template Playground that renders the template in the backend using Django's template engine, letting you even choose which version of Django to use.
It also support creating snippets, which allows sharing of specific template snippets in a cool “try, change & play with it” kind of way.
For example this snippet: https://tech-playground.com/snippet/literate-wonderful-kittiwake/
The whole thing is also a Django app in the background, which I will share some more on in the near future.

Cyantic - build complex objects from simple blueprints using pydantic
# What the project does
Cyantic lets you build complex types from simple blueprints in your pydantic models, with type-safety and validation built in.
**https://github.com/flywhl/cyantic**
* Type-safe blueprints with validation, since they are pydantic models.
* Reference other values using `@value:x.y.z`
* Import objects using `@import:x.y.z`
* Load data from environment variables using `@env:VAR`
* Define custom @hook handlers (see tests)
For my work, I have to instantiate a lot of `torch.Tensors`, and I wanted a way to do this from YAML specs (how I specify models). So I built a kind of middleware, which uses intermediary Pydantic models as blueprints, and instantiates them into full objects during pydantic's build process. Now I can pass in parameters (mean and standard deviation), and get a fully-built `Tensor` in a pydantic model.
This is now a library, Cyantic - named after cyanotype photography (i.e. the "blueprint").
# Target Audience
It's clearly useful for science/data-science work, esp as scientists start moving away from `dict`s to use pydantic.
I think this would also be useful for general config management, using the `@hooks` API. You can stitch YAML files together, re-use sections of YAML, etc..
# Comparisons
I haven't looked for alternatives, but would love to hear about other builder/aggregator libraries for pydantic.

Is it okay to use both the threading.Thread and ThreadPoolExecutor class for managing tasks in application using threads.

Need help hosting flask app
Hi,
I’m sure I’ll get hell for this as I often do, I’m an educator for a niche field and built a flask app with the help of ai, basically a flashcard tool to help me at my practice. App works great, no errors on the user side, now I want to host it so I can access it. Truth be told, I also want to share with others in my field.
I’m so frustrated with hosting, it’s true that ai led me down a road where I got lost, but it’s also true that I have a tool I couldn’t find anywhere else, a tool I’ve dreamed about since being in the field.
Any simple ways to get around this? Not opposed to fiverr, but I didn’t have great experience with them before. For the record I’ve tried PythonAnywhere, Heroku, and AWS and keep getting errors I cannot make sense of. I would LOVE to learn hosting so I could truly do it on my own, but tutorials go from “the back end talks to the front end” to “you need to configure the WSGI, route here route there” very quickly.

Logic in Views vs Logic on Models
Hey folks,
Apparently this is a frequently discussed topic.
Im doing a project using DRF. In this context i feel like the Views that are basically APIs should have logic, but my approach so far was that whatever touches a model, goes in the model.
Concrete example: one of my APIs has to change the Status of a Sales order. Then i will create a method in the SalesOrder model that will do the status change, along with any particular validation that it might want to do (example if you're changing it to completed/closed, ensure theres no open amount and the items were delivered)
Can you give me your thoughts about this approach and if its worth moving everything to either the views or to another "business logic" layer (or both)?
I dont really have crazy calculations or bigass logic for anything in particular, but i rather learn the proper way
Looking online i see all kinds of recommendations, the logic layer as well as the Thick Models, as well as "Model is simply the ORM". So i feel like it doesnt really matter as long as its consistent and is useful for the individual project?

Where to host Flask App
Hi everyone! I just developed my first flask app, and needed some assistance in getting it deployed as I've never done it before. My app uses multiple databases (SQLite currently) to keep track of events and participation for an organization I am in. I originally was going to use render since it was free but since it seems like it refreshes it won't be a good fit since it will wipe my dbs. I then looked at creating a PostgreSQL database on render but their free tier only lasts a month. If there is a way to host this for free I'd love to do that since the org is only about \~100 people and the website wouldn't be in use constantly and the likelihood of concurrent writes is very low. I was wondering if anyone knew a place where I could host this web app (hopefully for free), or for low cost if I can use SQLite as I'd rather not update everything atp. If anyone has any advice or helpful resources I'd greatly appreciate it!
