code-graph-rag Code-Graph-RAG builds knowledge graphs from multi-language codebases and enables AI-powered querying and editing. It uses Tree-sitter to parse ASTs across 11 languages, stores structural data in Memgraph, and translates natural language questions into Cypher graph queries. Unlike vector-based RAG, it preserves exact code relationships: call chains, inheritance hierarchies, and module dep... github.com/vitali87/code-…

Deprecate confusing APIs like “os.path.commonprefix()” The article argues that confusing APIs like Python’s os.path.commonprefix() should be deprecated because their misleading naming and placement cause developers to misuse them and introduce security vulnerabilities. It shows how decades of confusion around this function led to real path-traversal bugs and concludes that unsafe or misleading APIs should be replaced by clearer alternatives ... sethmlarson.dev/deprecate-conf…

Custom Data Structures in E-Graphs The post explores how Egglog’s e-graph framework can be extended with custom container data structures to represent algebraic structures (like multisets) more efficiently and reduce expression blow-up during rewriting. It shows that by embedding structural invariants into the data representation and using higher-order functions, you can express powerful rewrite rules without explosive gr... uwplse.org/2026/02/24/egg…

You’ve Been Underusing Dataclasses (These Tricks Are Wild) The video demonstrates seven powerful, lesser-known techniques using Python dataclasses, including automatic class registration, lightweight validation, cached derived values, and context manager patterns. It also shows practical uses such as CLI generation and explains advanced features like InitVar, highlighting how dataclasses can enable cleaner and more expressive Python designs. youtube.com/watch?v=Y9_h7e…

Validating data with pointblank in python One of the most common tasks of any organization is reviewing data to ensure that it is accurate and does not contain errors. Commonly, this is done by producing graphs or summary information like a median or mean and confirming that it looks reasonable. Pointblank is a newer tool that allows you to really dig into a dataset and task assumptions in a robust and reproducible manner. markpitblado.me/blog/validatin…

Designing for Model Swaps When LLM providers ship breaking changes, a poor architecture turns a config tweak into a 400-line PR. This post introduces seam-driven design - five narrow interfaces (provider, prompt, tools, config, observability) each independently swappable - illustrated with a working FastAPI + LangChain reference app, a practical checklist, and two hands-on drills readers can run immediate garybake.com/seams1.html

Using tox to Test a Django App Across Multiple Django Versions The article shows how to use tox to test a Django app across multiple Python and Django versions by creating isolated environments that install specific dependency combinations and run the same test suite. By defining a version matrix in tox.ini, developers can automatically verify compatibility across many Django releases and catch packaging or environment issues before users encounter them. djangotricks.com/blog/2026/02/u…

MicroGPT explained interactively Walk through Karpathy's 200-line GPT from scratch.
