The story of Pybinding - a python wrapper around C++...

The story starts with a common problem: Python is a fantastic language for rapid prototyping, data analysis, and orchestrating complex tasks. However, when it comes to raw computational speed, especially for number-crunching or highly parallelized operations, it can fall short. C++ and other compiled languages, on the other hand, excel in these areas. The question was: how do you get the best of both worlds? How do you write the performance-critical parts of your application in C++ while still enjoying the development speed and ecosystem of Python? The answer was to create a "binding" – a bridge that allows Python to call C++ code as if it were native Python. Early efforts in this space, such as Boost.Python , were powerful but often came with a steep learning curve and significant compilation overhead. They were a bit like using a sledgehammer to crack a nut – effective, but perhaps a bit unwieldy for many use cases. Have a look at how neat the python code looks; however, the actual job is done by the background C++. import libfoodfactory biscuit = libfoodfactory.make_food("bi") print(biscuit.get_name()) chocolate = libfoodfactory.make_food("ch") print(chocolate.get_name()) Do you like the story?

shadcn/ui vs Material UI Developer Guide 2026

\shadcn/ui and Material UI optimise for opposite priorities. Choose shadcn/ui to own your component code, ship a near-zero runtime, and control every pixel; choose Material UI (MUI) for breadth — 90+ components and a paid data grid — behind Google's Material Design. shadcn/ui has ~116,000 GitHub stars and ships copy-paste components; MUI has ~98,000 stars and ~7.3M weekly npm downloads. Both are MIT-licensed and free for commercial use. This guide covers the parts you only learn by shipping both: how each behaves in the Next.js App Router, the runtime cost, real theming and dark-mode code, forms, data tables, and migration mechanics. What's the real difference between shadcn/ui and Material UI? The difference is ownership, and it decides everything downstream. MUI is an npm dependency ( @mui/material ) you install and import from node_modules — you never touch the source. shadcn/ui is a copy-paste registry: you run a CLI, the component lands in your repo, and it is now your code. shadcn/ui is unstyled, built on Radix UI primitives and Tailwind CSS. MUI ships Material Design and an Emotion (CSS-in-JS) runtime. With MUI you install and import: bash npm install @mui/material @emotion/react @emotion/styled cta.tsx import Button from " @mui/material/Button " ; export function Cta () { return < Button variant = "contained" > Get started </ Button >; } With shadcn/ui the CLI copies the source into your project and you import from your own path — there is no library to upgrade or override: bash npx shadcn@latest add button cta.tsx import { Button } from " @/components/ui/button " ; export function Cta () { return < Button > Get started </ Button >; } That ownership changes how you customise. shadcn's button.tsx lives in your repo and uses class-variance-authority (cva) for variants — you add one directly: components/ui/button.tsx // components/ui/button.tsx — this file is yours const buttonVariants = cva ( " inline-flex items-center justify-center rounded-md ... " , { varia
