DevStories. EU is your audio companion for the new developer landscape. We publish three types of content: in-depth audio courses on frameworks and tools like FastAPI, Docker, LangChain, and many more (10-20 episodes each, built from official docs), quick Pulse episodes covering recent releases and emerging tools, and annual Special episodes with year-in-review recaps and industry predictions. Designed for learning away from a screen — on your commute, during a run, or while doing the dishes. Created and curated by Alex,...

PySpark: The Hidden Execution Tax Slowing Your Cluster 08.04.2026 2:22

Discover why perfectly written Python functions cause cluster compute spikes due to hidden Java-to-Python serialization bottlenecks. This 21-episode audio course breaks down how PySpark manages distributed memory, optimizes queries with the Catalyst optimizer, and prevents expensive network shuffles. Listen to the full course for free at DevStories. EU .

High-Performance Python Async: Hidden CPU Bottlenecks 08.04.2026 2:21

Your Python async application might not be bottlenecked by network latency, but by the CPU cycles wasted parsing text strings. This audio course explores how to eliminate this overhead using binary database protocols, uvloop, and optimized connection pooling. Listen to the full course for free at DevStories. EU .

SunPy: Why Standard Python Breaks Solar Data Analysis 08.04.2026 2:26

If you map a spatial grid onto the Sun, it instantly begins tearing itself apart because the star is a spinning fluid. This audio course explores how SunPy tracks dynamic solar coordinates, strictly enforces physical units, and safely crops arrays without corrupting your metadata. Listen to the full course for free at DevStories. EU .

Astropy: Why 64-Bit Floats Fail at Astronomy 08.04.2026 2:12

A standard 64-bit float cannot track a billion-year timestamp down to the microsecond without destroying its own precision. This 15-episode audio course explores how Astropy bypasses these hardware constraints, binds physical units to NumPy arrays, and processes massive remote datasets using HTTP byte range requests.

asyncio: Why Your Async Python Code Silently Fails 08.04.2026 2:27

Calling an asynchronous Python function without the await keyword leaves you with a useless coroutine object instead of executing your code. This free audio course explores how the asyncio event loop actually works under the hood, covering structured concurrency, memory management, and safe thread routing.
