Articles, Tutorials and Talks

Python.jl—Seamlessly blend Python and Julia

The talk introduces Python.jl, a Julia package that seamlessly blends Python and Julia syntax, allowing users to write code that mixes elements from both languages in a single environment. While presented as a lighthearted experiment, the project demonstrates Julia's flexibility in creating domain-specific languages and highlights the challenges of integrating two different programming languages.

The Python Package Index Should Get Rid Of Its Training Wheels
This article discusses challenges with storing pre-built binaries for Python packages on PyPI and proposes a solution for creating them on-demand to save space and make PyPI more sustainable.

Automatic async to sync code conversion
The article describes how Psycopg 3 implemented an automatic conversion system to generate synchronous Python code from asynchronous code, reducing code duplication and maintenance efforts. The process involves using Abstract Syntax Trees (AST) to transform async code into equivalent sync code, with custom transformations and helper functions to handle complex cases.

Inside Bento: Jupyter Notebooks at Meta

Meta has developed Bento, an internal platform that enhances Jupyter notebooks with features like version control, collaborative editing, and automated dependency management. This system, which handles over 150,000 notebooks and supports 18,000 monthly active users, aims to improve productivity and collaboration for data scientists and engineers across Meta's various teams and projects.

How to Design an AWESOME Function Signature in Python

This video demonstrates how to design a great function header in Python, highlighting aspects that are often overlooked but can significantly impact the quality of the code. Important considerations will be discussed to enhance coding practices and improve overall functionality.

Multi-dimensional Sparse Arrays in SciPy
The article explores multi-dimensional sparse arrays and their implementation in scientific computing, focusing on their efficiency in handling large datasets with mostly empty or zero-valued elements. It emphasizes the benefits of sparse arrays for memory optimization and computational performance in various data-heavy applications.

An In-Depth Guide to Contrastive Learning: Techniques, Models, and Applications
Discover the fundamentals of contrastive learning, including key techniques like SimCLR, MoCo, and CLIP. Learn how contrastive learning improves unsupervised learning and its practical applications.

rerankers: A Lightweight Python Library to Unify Ranking Methods
Re-ranking is an integral component of many retrieval pipelines; however, there exist numerous approaches to it, all with different implementation methods. To mitigate this, we propose rerankers, a Python library which provides a simple, easy-to-use interface to all commonly used re-ranking approaches.
