Common Pitfalls and Potential Optimizations in Django. |
|
The post explains how Python's type checkers reject certain Callable and Protocol overrides due to contravariant parameter rules, using a vegetable-peeler analogy to clarify the concept. It then shows how to resolve these issues safely with generics like TypeVar or PEP 695 patterns, avoiding the need to fall back on Any. |
|
The author demonstrates using Lean as an external SMT solver by translating proof goals into SMT queries and reconstructing the results back into valid Lean proofs. He builds a lightweight Python workflow that integrates Lean and SMT solvers seamlessly, enabling automated, proof-generating tactics within Lean. |
|
Ever wondered how to build a clean Python SDK without a giant god class? This video shows you how to design an SDK that uses multiple layers of inheritance to keep your code DRY and easy to scale. |
|
Last time, we built a hybrid concurrent.futures executor using inheritance. Today, we're building it again (twice!) using composition and functions only, to figure out which way is better and why. |
|
The post recommends using GNU Make with Python projects for automation entrypoints, preferring uv for fast interpreter/venv setup and delegating complex logic to Python task runners, keeping the Makefile minimal and focused. |
|
A complete guide to building autonomous systems with agentic AI workflows—covering core concepts, tools, and real-world applications. |
|
The post discusses how Python on Windows (often preinstalled via the Microsoft Store) can be used as a surprisingly effective tool for offensive security and malware operations, thanks to its rich standard library, isolated package management, and low-profile presence in corporate environments. It outlines methods such as malware delivery, offline package installation, and leveraging ctypes for unmanaged code execution, emphasizing both the challenges for defenders and the advantages for attackers who use Python for its legitimacy. |
|
Uncaught exceptions will crash an application. If you don't know how to log these, it can be difficult to troubleshoot such a crash. Let's walk through this gotcha and see how to fix it. |
