OSPF stands for Open Shortest Path First. It is an open-standard link-state interior gateway protocol used by routers to learn network topology and calculate routes inside an autonomous system. This is the first Open-Source Networking Engineer Certification (OSNEC) lesson. The technician pathway teaches device addressing and verification; the engineer pathway now moves into routing behavior,…

A MAC address, short for Media Access Control address, identifies a network interface on a local network. You will commonly see it written as six pairs of hexadecimal characters, such as 3C:52:82:1A:4F:90. In OSNTC.001, you learned that an IP address identifies where a device communicates on an IP network. A MAC address serves a different…

A satellite launched today carrying a strange proposition for the future of energy and computing: collect sunlight in orbit, turn it into a laser, and aim that energy back toward Earth. Cowboy Space’s Reason-1 rode to orbit on SpaceX’s Transporter-18 mission. The spacecraft is intended to attempt a kilowatt-class laser power-beaming experiment from low Earth…

Quantum computing does not have an NVIDIA yet. It does not even have agreement on what the winning quantum transistor should look like. That is what makes the industry unusually interesting in 2026. Billions of dollars are flowing into machines built around radically different physical ideas: superconducting circuits cooled near absolute zero, trapped ions suspended…

Applied Materials and Besi are expanding their AI packaging partnership into next-generation hybrid bonding, TCB, die-on-panel integration and photonics-enabled interconnects.

A string is text stored in a program. In C++, std::string can hold words, player names, messages, and labels. Unlike the numbers we stored in OSC++.012, a string stores a sequence of characters. This is a new subject, not another vector lesson. 1. Make a String The #include <string> line makes the standard string type…

WatchGuard patched CVE-2026-86131, a critical Fireware OS flaw that can let an attacker-controlled BOVPN-over-TLS server execute root commands on a connecting Firebox.

Bill Gates just made the “AI kill switch” debate sound less like science fiction and more like an engineering problem with the wrong name. In a new NBC interview, Gates argued that simply having a giant OFF button is not enough. AI systems are not yet armies of autonomous machines that cannot be disconnected, he…

Intel Diamond Rapids turns Xeon into a 256-core chiplet fabric with four compute blocks, two centralized fabric hubs, 1.28 GB of LLC, and UCIe-S package links.

A humanoid in a hospital gown appears to bolt through a crowded city center while police officers and emergency vehicles give chase. The clip looks just plausible enough to trigger the question everyone now asks about robotics: did a machine actually go rogue? No. But the reason millions of people had to ask is the…

Volantis raised approximately ₿1,053 ($88 million) to develop A-1, a photonic-memory inference architecture using integrated micro-VCSEL links to attack AI’s memory wall.

An interlock or permissive adds a condition to an electrical control circuit. Instead of allowing a device to run whenever START is pressed, the circuit checks whether another required condition is satisfied first. This lesson builds directly on OSETC.017. The simple technician idea is: a permissive says “this must be true before you may start,”…
