Scope Boundaries for Notebooks — Research Study on an extension I've been developing

Hi Everyone. My name is Eric Rawn. I’m a PhD student at UC Berkeley working with my advisor Professor Sarah Chasins. I research how to make notebook programming environments better, and have been working on an extension for notebooks which introduces scope boundaries to collections of cells. We think this might help programmers avoid some of the pain points with notebooks, but we won’t know until we study its use in the real world. The goal is to make it easier to keep variables tidy within a notebook without requiring programmers to change how they like to use notebooks. We’re interested in evaluating how our extension aids how real users program (you all!), and so we’re running a 4-6 week study with folks who use Jupyter notebooks regularly in their everyday programming.

The extension will log some usage data locally on your machine, which you'll send to me at the end of the study. We'll then spend about an hour chatting about your experience, the kind of work you do daily, how you use notebooks, and any other thoughts or feedback you have. Participants will be compensated for their time spent interviewing, at $30/hour. The consent form has detailed information about the

Shed Skin restricted-Python-to-C++-compiler 0.9.9

I have just released version 0.9.9 of Shed Skin, a restricted-Python-to-C++ compiler. It comes with a whole host of small improvements, and also a nice new (constructive solid geometry) example, which becomes about 15 times faster on my system (not 15%.. 15 times!).

If you think this is a cool project, please consider helping out. There is always enough work (low-hanging fruit even) on both the Python and C++ side.

zealot: prevent N+1 queries in Django

hey everyone!

i just released zealot, a library for detecting N+1 queries in your Django project.

i've wanted something like this for a long time. there are some similar libraries out there, but none of them did everything i wanted, and the most popular would miss certain types of N+1.

zealot is pretty simply: install it, and it'll raise an exception (or log a warning) whenever it detects an N+1 query, with a helpful error message so you can fix it and be on your way.

all feedback is very welcome!

I made a Python library to plot chemical trends | Plotium

# What does my Project do?

Plotium is a python library used to plot chemical trends like Atomic radii, Electronegativity, etc of specific parts of the periodic table, like types of elements, group or a specific block.

Right now, Plotium can plot trends of:

1. Electronegativity

2. Density

3. Atomic Radii

4. Melting Point

5. Boiling Point



Divided into:

1. Block Wise (S,P,D,F)

2. Types (Actinoids, Lanthanoids, etc)

3. Groups (1 - 18)

# Target Audience

Students/people who love chemistry. This library will also be useful for teaching students several exceptions and trends.

# Comparison

I haven't seen any trend plotter other than one hotmap plotter. But what I'm aiming is graphing these trends.

# GitHub

Does anyone know of an extension that will auto create a client class for all my endpoints?

Say I’m using DRF with a bunch of model viewsets. I have a swagger gen extension but is there one that will collect all those same endpoints and create a Python class or file containing all of them? Like using requests or urllib or something like that and have all the endpoints auto implemented for you? I’m sure it’s possible (and opinionated) just haven’t come across anything I’m aware of or could find on google.

Django cache does not support hash(redis)

I am studying django and i just learned that django's build in cache framework DOES NOT support redis's hash.

Is it strange? for such a mature framework but its built in cache does not support in-memory database's hash? i asked chatgpt and they confirmed it.

I manually created my own function that uses the built in cache.set and put a json.dumps(dict) in it and in my redis GUI it still shows up under the string. I am worried that my own custom function may not be as efficient as the redis's hash since its really considered as a string. Is it advisable to put a dict as string or should i just opt out of the django cache and use a third party library to handle redis?

How to deploy selenium based flask app to VPS with gunicorn and nginx

Hi, I have a basic web scraping price comparison app. I wanted to deploy it on the oracle free tier for cloud hosting. I’m quite new to this so I have a few questions.

How can I set up multiple workers to service multiple requests simultaneously? What would I need for that?

What is the procedure for deploying this app to oracle cloud? I do have a domain but I don’t know how to make that work.

I’ve gone through way too many YouTube videos and it’s all quite confusing. I’d really appreciate any help or video links.

Just finished my first week learning Python!!

Hey guys! My name is Christian (22M). Ever since my sophomore year in high school, when I began to learn more and more about computers by taking a simple html class for my cs credit, I have wanted to do more in this field. However, between bouncing around from many different ideas of what I wanted to do for the rest of my life, I ended up landing myself graduating from college with an associate in applied science for Engineering Systems Technology.

Since I turned 18, I have continuously worked in a field with utility scale electrical equipment, focusing on the software/programming side for the components that control the flow/state of that energy. I.E. PLC, STM32, JTAG, DSP, Custom Mod-bus. I have a decent amount of experience in several different applications but could never say that I truly KNEW what to do beyond basic debugging and integration.

I have recently started the 100 Days of Code challenge course on Udemy which was one of the highest rated courses for learning Python. I seem to be picking it up pretty quick but and truly starting to wonder if even after completing this course will I actually be able to land a

How much data validation is healthy?

How much manual validation do you think is healthy in Python code?

I almost never do validation. I mean, when reading data from files or via an API, or from anywhere that I don’t control with my code, I would generally do validation via Pydantic or Pandera, depending on the type of data. But in all other cases, I usually supply type hints and I write functions in complete trust that the things that actually get passed live up to what they claim to be, especially because my point of view is that MyPy or Pyright should be part of a modern CI pipeline (and even if not, people get IDE support when writing calls). Sometimes you have to use # type: ignore, but then the onus is on the callers’ side to know what they’re doing. I would make some exception perhaps for certain libraries like pandas that have poor type support, in those cases it probably makes sense to be a little more defensive.

But I’ve seen code from colleagues that basically validates everything, so every function starts with checks for None or isinstance, and ValueErrors with nice messages are raised if conditions are violated. I really don’t like this

Django book recommendations

Hello, I'm a new developer. Currently really proficient with the flutter framework and I have a rather solid understanding of OOP. I love to read on frameworks and coding I'm general as I am able to get the knowledge in more depth than I would in a video or tutorial.

Do any of you know an excellent Django book for me to get to know the framework.

P.S I prefer human recommendations than Google search results when it comes to book recommendations. Because with good seo and marketing even a not so good book can be a first result.
