The eighth annual developer survey report from the Python Software Foundation and JetBrains is out! It reveals some fascinating trends: 86% of respondents use Python as their primary programming language, 50% of developers have less than two years of coding experience, and data science now dominates Python applications.
2、Python: File streaming @237MB/s on $8/m droplet in 507 lines (stdlib)
The author built a WSGI core called Axon that achieves 237MB/s file streaming performance on an $8/month server using just 507 lines of pure Python standard library code. The framework maps HTTP request bodies to iterable byte streams, processing data on-the-fly while maintaining constant memory usage of just a few dozen KB.
Facing the problem of malicious AI crawlers creating tons of throwaway sessions that push out real user sessions from cache, the author suggests replacing traditional LRU (Least Recently Used) with LFU (Least Frequently Used) caching strategy. By configuring Redis's volatile-lfu mode, you can effectively protect frequently accessed user sessions and ensure critical business data like e-commerce shopping carts don't get flushed out by malicious traffic.
4、Context Engineering — A Comprehensive Hands-On Tutorial with DSPy
This article dives deep into context engineering, demonstrating through the DSPy framework how to break down complex problems into multiple subtasks and have different AI agents collaborate to complete them, avoiding the performance degradation that comes from cramming all information into a single context.
A deep dive into Python proxy object implementation principles, showing how to achieve transparent object call proxying through special methods. Demonstrates how to leverage this mechanism to develop advanced features like database connection pools and file system abstractions.
6、Preventing Domain Resurrection Attacks
PyPI introduces new security mechanisms to prevent domain resurrection attacks. When a user's email domain expires, attackers might purchase that domain and gain account control through password resets. PyPI now regularly checks domain status and cancels related email verifications once a domain enters redemption period, effectively blocking these supply chain attacks.
7、Algorithms through the lens of symbolic pattern matching
This article shares how to design algorithms using symbolic pattern matching, transforming graph theory problems into mathematical expression operations through the Symbolica library. The author demonstrates implementing algorithms like factorial calculation and graph connectivity detection using pattern replacement. While not the most efficient approach, it offers an elegant way of thinking about algorithms.
8、A practical introduction to Constraint Programming using CP-SAT and Python
This article introduces constraint programming through a declarative programming paradigm, describing problems using variables and constraints. Using Python's CP-SAT solver, it demonstrates how to solve discrete optimization problems like warehouse location and logistics scheduling, showcasing the power of constraint programming in handling complex combinatorial optimization scenarios.
An old blog post by Guido van Rossum revealing the origin of the BDFL (Benevolent Dictator For Life) title. At the first Python Software Association meeting at CNRI on April 18, 1995, each attendee came up with titles starting with "First Interim," with Guido's being the most humorous. This title was likely suggested by Ken Manheimer or Barry Warsaw and became an important symbol of Python community culture.
This article shows how to create terminal rain drop animation effects using pure Python standard library. Using deque data structures for management, characters 'v' and '|' represent raindrops and trails respectively, combined with random number generation and time delays to create smooth rain animations. The code is elegant and concise, creating impressive visual effects with just a few dozen lines.
11、Timeouts and cancellation for humans
The Trio library author explores the design challenges of timeout handling in I/O operations, sharing Trio's cancel scopes solution. Through cancellation tokens and scope mechanisms, it solves the problems of traditional timeout APIs being difficult to abstract and compose, providing a more human-friendly timeout control approach for asynchronous programming.
12、The only two log levels you need are INFO and ERROR
The author challenges traditional logging level thinking, arguing that complex log level systems (like WARNING, DEBUG, TRACE) aren't actually practical. By analyzing the two core purposes of logging—"errors that need alerts" and "information that helps debugging"—they propose that just ERROR and INFO levels are sufficient, while suggesting improvements to log utility through structured logging, request IDs, timestamps, and other methods.
