In this article, you will learn different math concepts such as gradient descent, derivatives, matrix, chain rule, and how to use those concepts to explain and solve some back propagation examples from scratch (in artificial neural network). Neural networks are a family of powerful machine learning models. This technology has been proven to excel at solving a variety of complex problems in engineering, science, finance, market analysis and many more.

Note: Basic knowledge about derivatives is recommended to get the best out of this article.

There are two directions in…

For the last couple of years, I’ve been hearing more and more about a language named Rust. Well known as the most loved language on Stackoverflow’s annual developer survey for the fifth year in a row, Rust is famous for its memory safety without a garbage collector and concurrency without data races! But Rust is also feared as a hard-to-learn language, scaring away many developers. For way too long, I postponed learning Rust. That was a mistake.

Cloud-native development makes way for applications that are packaged in containers, deployed as various microservices, managed on elastic infrastructure, built on agile DevOps processes, and delivered in continuous workflows. The cloud-native DevOps abstracts the underlying compute, storage and networking primitives, abstaining the concerned DevOps teams’ direct access to programming interfaces (APIs). With orchestrator handling resource allocation itself, they are reduced to mere policymakers.

Cloud-native development tools, such as Kubernetes, simulate a flat network tied to present networking topologies and primitives of cloud vendors. …

“No,” he said eventually, “what?” There was silence.
Then Albert straightened up and said, “Damned if I know. Probably they get answers, and serve ’em right.”

Babelfish: A Universal Code Parser

Babelfish is a self-hosted server for source-code parsing: it has the power to parse all kinds of file, in any supported language, extracting an Abstract Syntax Tree and converting it into a Universal Abstract Syntax Tree (UAST). This UAST enables further analysis and transformations with either the included tools or your own tools by providing a standard open format.

The project has been developped to be able to parse millions of repositories. …

Last March 16, Github announced that an agreement was signed to acquire NPM.

Despite the mistrust of the open source community vis-à-vis Github (recently bought by Microsoft), the world’s leading development platform consolidates its positioning and its strategy by acquiring NPM, the leading supplier of the Javascript application packages.

With 3 million packages, 75 billion downloads a month and 11 million developers, NPM is the supply chain platform where maintainers and developers deliver and consume Javascript and node JS code.

Deploying a website or API often feels like :

  • wrangling Docker images…
  • herding virtual machines…
  • generating buckets and buckets of CI/CD pipelines…
  • iterating upon dependencies…
  • growing a magnificent Kubernetes…
  • framing monitoring…
  • and more…

It’s the long and repetitive work of the DevOps.
Luckily there is a way to automate this!
