GNU Radio – the Free and Open Software Radio Ecosystem

GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available, low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic, and commercial environments to support both wireless communicationsContinue reading “GNU Radio – the Free and Open Software Radio Ecosystem”

Is Space Pixelated? The Quest for Quantum Gravity

The universe itself may be similarly pixelated. Scientists such as Rana Adhikari, professor of physics at Caltech, think the space we live in may not be perfectly smooth but rather made of incredibly small discrete units. “A spacetime pixel is so small that if you were to enlarge things so that it becomes the sizeContinue reading “Is Space Pixelated?

Build a Weather Station with Elixir and Nerves

Build and deploy a production-grade weather station sensor hub using Elixir and Nerves, all while leveraging the best practices established by the Nerves community for structuring and organizing Nerves applications. Capture all of your weather station sensor data using Phoenix and Ecto in a lightweight server-side application. Read more…

Jailer: A tool for database subsetting, schema and data browsing

It exports consistent, referentially intact row-sets from relational databases. It removes obsolete data without violating integrity. It is DBMS agnostic (by using JDBC), platform independent, and generates DbUnit datasets, hierarchically structured XML, and topologically sorted SQL-DML. Read more…

GitHub will natively support Mermaid diagrams

Mermaid is an incredibly popular Markdown-inspired syntax used to visualize workflows, software architecture, and abstract concepts in documentation. Support for displaying Mermaid diagrams has appeared on GitHub’s top list of feature requests since 2015. In its absence, many developers simply added screenshots to their Markdown. Today, we’re excited to add native support for Mermaid whereverContinue reading “GitHub will natively support Mermaid diagrams”
