I made a python program that gives LLMs running locally the power to search the internet for LLMs ru
Hey Reddit!
I'm excited to share a project I've been pouring countless hours into: Web-LLM Assistant. It's a Python program that gives local LLMs running via llama.cpp the power to search the internet and provide up-to-date answers.
Here's how it works:
1. You ask a question to the LLM.
2. The LLM crafts a search query and selects a timeframe.
3. It performs a web search, collecting the top 10 results.
4. The LLM picks the 2 most relevant results and fully web scrapes them.
5. If the information is sufficient, it answers your question.
6. If not, it refines the search up to 5 times to find the best answer.
This means your local LLM can now tackle questions about recent events or topics outside its training data!
Key Features:
* Real-time web searching
* Intelligent result selection
* Full web scraping of chosen results
* Iterative search refinement
* Works with your local LLM setup
I'd love for you to check it out and give it a spin! You can find the project on GitHub:

Enhance Your Django Project with dj-logging: A Powerful and Easy-to-Use Logging Solution
Today, I’m excited to share a new Django package I’ve been working on called dj-logging! dj-logging is a logging solution tailored specifically for Django projects.
It’s designed to be easy to set up while offering powerful features to help you keep track of what’s happening in your application.
Let me walk you through some of its key features: Effortless Setup: You can get started with logging in just a few steps, with sensible defaults right out of the box.
Level-Based Logging: Automatically logs each level (INFO, WARNING, ERROR, etc.) into its own file, making it easy to track down specific types of messages.
Colorized Console Output: Logs are color-coded in the console, so you can quickly spot different log levels at a glance.
Email Notifications: Critical errors or issues? No worries—dj-logging can send email notifications for ERROR and CRITICAL logs, keeping you informed in real-time.
Request Middleware: The package includes a middleware that logs essential request details like the request path, user info, IP address, and browser type—perfect for debugging and monitoring.
Highly Customizable: You can easily tweak log formats and handlers to suit your project’s needs.

Avoid redundant calculations in VS Code Python Jupyter Notebooks
Hi,
I had a random idea while working in Jupyter Notebooks in VS code, and I want to hear if anyone else has encountered similar problems and is seeking a solution.
Oftentimes, when I work on a data science project in VS Code Jupyter notebooks, I have important variables stored, some of which take some time to compute (it could be only a minute or so, but the time adds up). Occasionally, I, therefore, make the error of rerunning the calculation of the variable without changing anything, but this resets/changes my variable. My solution is, therefore, if you run a redundant calculation in the VS Code Jupyter notebook, an extension will give you a warning like "Do you really want to run this calculation?" ensuring you will never make a redundant calculation again.
What do you guys think? Is it unnecessary, or could it be useful?

Flask/Werkzeug Password Hash Issue
I've had a production application or 2 years now. It's a bit outdated now, running Flask 2.1.3 and Werzeug 2.0.3 or similar.
I've updated all the code now to support Flask 3.0.0.
It works fine! The issue is now the migration. If I push LIVE the latest build, Werzeug doesn't support SHA256 anymore, you have to use PBKDF2:SHA256 when generating the password hashes.
The issue is my entire database over 30,000 users off the application passwords are hashed using they legacy Werzeug hash. I cannot see ANY way in the docs to convert the legacy hash to the new hash!
So current the Flask 3.0.0 version is working fine but NOBODY can authenticate in the test suite, due to this password hash issue.
Has anybody come across this, how did they migrate?
UPDATE: I managed to go back into the 2.0.3 version REPO of Werkzeug, and copy the hash there, so now if a user logs in it attempts to match the hash, if it errors with "ValueError" due to the hash being unsupported, it then runs the legacy hash code, if it matches that, then it converts it to the new hash method and updates the postgresql database.
Cheers.

Using Wikipedia views to build an alternative to the deprecated Google Correlate
If you are from the old days of the internet you might remember Google Correlate.
You could draw a line and it would show you similar search patterns. I kind of miss tinkering with it, so I tried to build my own with Python and open data:
* Scrape Wikipedia page views
* Transform data into a pivot table (columns = title, y = views per day)
* Use similarity search to find correlated articles
And finally we can find the closest neighbor in Python with:
from sklearn.neighbors import NearestNeighbors
nn = NearestNeighbors(n_neighbors=25, algorithm='auto',metric='cosine')
nn.fit(data)
distances, indices = nn.kneighbors(query.reshape(1,-1), n_neighbors=50)

I created my first ever API using flask
I've been tinkering with Python for a few years as a hobby (I'm in product management, not a developer).
Recently, I decided to create my first API using Flask. I wanted something very simple but fun, so I took inspiration from the classic Chuck Norris joke API that's been around forever.
Here's what I did:
1. GET joke script: I built a Python script to hit the Chuck Norris random joke endpoint, save to SQLite, and check for duplicates as I insert new jokes. The script hits the endpoint every 0.5 seconds, going through dedupe/save logic while ignoring dupes. I let it run overnight and ended up with 9000+ jokes in my DB! TY chucknorris.io!
2. New Chuck Norris API: I chose Flask (since I know it best) along with SQLite DB to build the endpoint. I also created a Chuck Norris-themed documentation page that I had chatGPT spice it up a but with some Chuck Norris inspired humor. Probably a little overboard but it was fun.
You can check out my first API here: http://cnichols1734.pythonanywhere.com
Let me know what you all think! I'm pretty excited about how it turned out, especially given that this is my first real API project. Any feedback or

Flask App Deployment
Hi, I have finished building a Flask app and have tried numerous deployment services (PythonAnywhere, Vercel, Render, etc.). I've even tried Google Cloud. My app uses AI and is using meta.ai for its AI features. Using meta.ai makes API calls to Meta. When running locally, the app works as expected. However, when deploying, I've received a series of errors that I have been unable to solve. PythonAnywhere did not include meta.ai in its whitelist of sites, and Render and Vercel kept telling me that the requests were timing out, which has never been an issue when testing. I'd appreciate it if anyone could provide any alternatives to the platforms above that would enable me to deploy my app.
Thank you in advance!

Tiny BASIC in Python
# What My Project Does
Have you ever wanted to program like your grandparents did in 1976? For my first Python project, I developed Tiny BASIC in Python: [https://github.com/John-Robbins/tbp ](https://github.com/John-Robbins/tbp) (tbp for short). Wanting to dive into programming languages, I needed an easy target language so I could develop all parts of an interpreter.
My target was the [Tiny BASIC](https://en.wikipedia.org/wiki/Tiny_BASIC) language first proposed by Dennis Allison in the first issue of [Dr. Dobb’s Journal of Computer Calisthenics & Orthodontics in January 1976.](https://archive.org/details/dr_dobbs_journal_vol_01/mode/2up) Special thanks to [Dr. Tom Pittman](http://www.ittybittycomputers.com/IttyBitty/TinyBasic/index.htm) for posting much of the documentation of his implementation sold the same year.
Features:
* Full language support, including the USR function.
* A full **DEBUGGER** built in with breakpoints, single stepping, call stack and variable display.
* Loading and saving programs to/from disk.
* A built-in linter for Tiny BASIC code.
* Complete documentation with development notes (over 17,000 words!)
* Full GitHub Actions CI implementation that work with branch protections for code and the documentation web site.
* 290 individual unit tests with 99.88% coverage across macOS, Windows, and Linux.
The [README](https://github.com/John-Robbins/tbp) for tbp has a GIF showing off tbp's functionality, including using the built in debugger to cheat at a game. Not that I advocate cheating, but it made

Help / Advice on Datatables in Django
Hi there,
I'm making a website that displays a lot of dynamic tabled data. After doing a bunch of research, I've sort of settled on Datatables - a JS library for displaying the tables that looks quite 'modifiable' and that's to my liking.
I'm using Django and Tailwind, and I've now noticed that Datatables overrides and messes up the Tailwind styling on my page even if I put the Tailwind CSS after the Datatables but I suspect because I'm loading in my tables with HTMX and initializing them after the swap that it reloads the DT CSS.
What does everyone else use when it comes to displaying tables? I like DT because it gives easy sorting and column highlighting and searching and all that jazz which is sort of what I'm after.

Which DB to use with my Flask app?
Hello! I'm working on designing a Flask app for an education project and trying to decide how to implement its DB. The web app is essentially a series of multiple choice / FITB / other types of Q&A behind a log in for each student. I expect that at its peak, about 60 students will be using the app simultaneously. Given they'll be answering lots of questions in succession, and I'll be writing their answers to the database, I expect the application will be both read and write-intensive. I've read that SQLite doesn't work as well for write-intensive applications, so my hunch is that a cloud MySQL server that I beef up during peak usage will be the best approach, but I wanted to get other opinions before committing.

Ruby on rails vs Django vs Laravel (Startup edition)
Hi, whats your honest opinion on Ruby on rails vs Django vs Laravel ?
Personally i have used all three of them just because of curiosity, what i have learned is:
- Ruby on rails -
If you use linux then i recommend learning ror because some of the gems or installation errors is pain in windows.
The scaffolding is just amazing. You only need one command to create crud which gives you both json for api and web routes.
Nowdays it uses hotwire which comes deafult. Its just like ajax so your website feels lil bit like SPA.
Best for - Livestream websites, very fast developement and get your product to market compared to django or laravel, hard to find good developers.
Downside i faced - No good tutorials, errors in windows, no community.
- Django -
The App is amazing like you can just create a feature and use it in any other project.
The Admin is very useful im impressed with it.
Feels like i have to write much more code compared to ror or laravel.
Open source and control over everything.
Best for - Social media, scalability and adding more features as website grows, AI/ML is the future, very easy to find good developers.
Downsides i faced - No
