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,”…

Fujitsu MONAKA uses 2nm silicon for 144 Arm cores while moving the entire last-level cache onto separate 5nm SRAM dies in a tightly coupled 3D chiplet design.

A ladder diagram is a simple way to draw and understand an electrical control circuit. It gets its name because the drawing resembles a ladder: two vertical rails with horizontal lines, called rungs, between them. This lesson builds directly on OSETC.015 and OSETC.016. You already learned about relay and contactor coils, normally open and normally…

Marvell publicly demonstrated its monolithic 3 nm Teralynx T100 Ethernet switch at AI Infra Summit 2026, combining 102.4 Tbps, 512-port radix and adaptive routing.

IBM’s next-generation mainframe CPU natively executes Arm and z/Architecture on the same physical core, bringing modern Arm software closer to mission-critical data.

A motor starter is a control assembly used to start and stop an electric motor while providing important motor protection. A common magnetic starter combines a contactor with an overload relay. The contactor switches power to the motor; the overload relay helps protect the motor from damaging sustained overcurrent. This lesson builds directly on OSETC.015.…

Boston Dynamics has given Atlas a new set of hands, and the most interesting part may be what the engineers deliberately left off: a fifth finger. In its October 1 demonstration, Boston Dynamics says the new Atlas hand has 13 degrees of freedom, direct actuation and a design built for high-fidelity simulation and sim-to-real reinforcement…
