Polymorphism means “many forms.” In Python, it lets the same method name or operation work with different kinds of objects. In OSPython.013: Inheritance Basics, we learned that child classes can inherit and override behavior. Polymorphism builds directly on that idea: different objects can respond to the same method call in their own way. One method…

Inheritance lets a new Python class reuse the useful parts of an existing class and then add or change behavior of its own. In OSPython.012: Classes and Objects, we created classes as blueprints. In this lesson, we connect two blueprints: a general parent class and a more specific child class. Start with a parent class…

Honda and Redwire are exploring a robotic research system for future commercial space stations that combines Honda’s multi-fingered robotic hand with Redwire’s STAARK robotic arm and experiment-locker technology. The companies’ Oct. 1 announcement describes a concept intended to automate portions of experiment handling, sample transfer and other routine laboratory work in orbit. The idea is…

Large networks can learn hundreds or thousands of routes. Route summarization lets a router advertise one broader route that represents several smaller, contiguous networks. The result can be a smaller routing table and a cleaner routing design. This engineering lesson builds on OSNEC.001: OSPF Fundamentals. Here, the focus is the underlying summarization calculation before applying…

Armv8-M is a 32-bit processor architecture designed for microcontrollers, embedded systems, IoT devices, industrial controllers, secure hardware, sensors and other systems where low power consumption, deterministic behavior and a relatively small silicon footprint are important. It belongs to Arm’s M-profile architecture family, rather than the higher-performance A-profile used by application processors or the R-profile designed…

Agility Robotics and FORT Robotics are extending humanoid safety beyond the robot itself, adding an external bridge that can connect Digit 5 with the safety systems already operating across a factory, warehouse or logistics facility. The companies announced the expanded partnership on October 1. Their new three-part architecture combines a safety pendant, on-robot communications and…

Bitdeer has secured customer commitments for more than 70% of its 21.7 MW A201 AI data center in Johor Bahru, Malaysia before the facility has even been energized, attaching more than $1.7 billion in expected five-year revenue to a site scheduled to power on in the first quarter of 2027. The company’s September 29 disclosure…
