Most teams facing a slow Python system reach the same conclusion: “We need to rewrite this in C++.” Sometimes that's true. But often the real problem isn't the language — it's the algorithm. In the first post of our “From the Trenches” series, we share a real engineering story: A medical imaging prototype that took 47 minutes to process a dataset. The team was preparing for a full rewrite. Instead we profiled the code. What we discovered: • The bottleneck wasn't Python itself • The algorithm was doing billions of redundant computations • GPU acceleration alone wasn't enough By combining profiling, algorithm redesign, and GPU acceleration, we reduced runtime from: 47 minutes → 8 seconds No rewrite required. In the article we walk through: • The profiling tools we used • How we found the real bottleneck • Why algorithm optimization beat a C++ rewrite • When GPU acceleration actually helps If you're working with Python performance issues, this might save you a rewrite. 📘 Full article below. #Python #SoftwareEngineering #PerformanceEngineering #GPUComputing #Profiling #MachineLearning #EngineeringStories

Why Python Feels Really Slow — And How I Got a 1500% Boost Python feels slow because the interpreter pays a tax on every loop, attribute access, and dynamic type check. I hit that wall building RoX, my AR spatial engine: 16 million voxels per object, millions of Python-level checks, and a pipeline that crawled. The fix was brutal and obvious—stop doing heavy numeric work in Python and let compiled layers do the work. Rewriting the hot path with NumPy vector ops and Numba’s njit turned a minute-long grind into something that runs in seconds. The result: from a 30-second render time to a measly 2 seconds while running three parallel pipelines—MediaPipe, OpenCV, and moderngl draw calls—in the background, roughly a 1500% speedup on the voxel pipeline. #XR #SpatialComputing #ComputerVision #MediaPipe #OpenCV #OpenGL #EdTech #GameDev #RoX

Ever noticed your Python AI/ML code recalculating the same things over and over? 🤔 Especially with recursive functions or repeated feature engineering? It's a common performance bottleneck that can really slow down your models. But what if your functions had a memory? Enter `functools.lru_cache`! 🧠 This super handy decorator allows your functions to "remember" the results of expensive calls. So, if they're called again with the same arguments, they instantly return the cached result instead of re-running the computation. It's a game-changer for speeding up everything from dynamic programming algorithms within your models to complex data preprocessing steps. Imagine drastically cutting down training or inference time with just one line of code! ⚡️ Have you used `lru_cache` to speed up your AI/ML projects? Share how it helped! 👇 #Python #AIML #MachineLearning #CodingTips #Performance

Building an AI agent doesn't require a master's degree in computer science. It requires a fundamental understanding of how to guide a reasoning engine. When you build a ReAct (Reason + Act) agent from scratch in pure Python, you learn a profound truth: the magic isn't in the code. The code is just a simple while loop. The magic is in the System Prompt. 📌 Read More: https://lnkd.in/d-ZQNRGZ

Do you know what an image actually is in technical terms? An image is just a 2D matrix. Each cell in that matrix contains RGB values (Red, Green, Blue). When all these values come together, they create what we see as an image. That’s what clicked for me while learning OpenCV. Instead of thinking “this is a photo”, you start thinking: this is just data. In my project: – I sent an image from React to a Python backend – Converted it from base64 → bytes → NumPy array – OpenCV processed that array to detect faces – Then sent it back to the frontend And what about video? A video is just a collection of images (frames). When you display around 30–60 images per second, it looks like motion. So again, not magic — just fast processing of images. This changed how I think about computer vision. #OpenCV #Python #ComputerVision #LearningInPublic

Curve fitting is straightforward, until you scale it. In high-throughput settings, fitting 100+ dose–response curves quickly becomes a bottleneck: manual workflows don’t scale, and reproducibility suffers. I’ve been working on automating 4PL curve fitting in Python to make this process faster, consistent, and reusable across datasets.

I built a Python mini-project that converts a normal photo into a realistic pencil sketch and others sketches using only NumPy, OpenCV, and Pillow - without any advanced computer vision libraries. This project focuses on applying core concepts of image processing by treating an image as a numerical matrix and performing mathematical transformations on pixel values. Key concepts used: Image as NumPy array (matrix of pixels) Grayscale conversion using weighted RGB values Image inversion (intensity transformation) Convolution-based blurring using a custom kernel Dodge blending technique to create sketch effect Contrast enhancement and visualization using CV2 This project helped me understand how images can be manipulated using pure mathematical operations and array processing in Python. fully open-source @ https://lnkd.in/eiCnU69C inspired by: "if a non-stochastic data-less approach can be taken to solving a problem, then machine learning should never be applied."
