A brief tour of the PDP-11, the most influential minicomputer of all time

Posted by in categories: military, nuclear energy, robotics/AI, space

Early PDP-11 models were not overly impressive. The first PDP-11 11/20 cost $20,000, but it shipped with only about 4KB of RAM. It used paper tape as storage and had an ASR-33 teletype printer console that printed 10 characters per second. But it also had an amazing orthogonal 16-bit architecture, eight registers, 65KB of address space, a 1.25 MHz cycle time, and a flexible UNIBUS hardware bus that would support future hardware peripherals. This was a winning combination for its creator, Digital Equipment Corporation.

The initial application for the PDP-11 included real-time hardware control, factory automation, and data processing. As the PDP-11 gained a reputation for flexibility, programmability, and affordability, it saw use in traffic light control systems, the Nike missile defense system, air traffic control, nuclear power plants, Navy pilot training systems, and telecommunications. It also pioneered the word processing and data processing that we now take for granted.

And the PDP-11’s influence is most strikingly evident in the device’s assembly programming.

Doomsday Nuclear Clock 2024 Gets Reset as Weapons Fears Rise

Posted by in categories: existential risks, military

The 2024 nuclear doomsday clock has been reset, but there is still time for final revisions.

The clock was created in 1947 by the Bulletin of the Atomic Scientists, a nonprofit that was founded in 1945 by Albert Einstein and University of Chicago scientists who helped develop the first atomic bomb in the Manhattan Project. It began because of escalated fears of a potentially catastrophic nuclear arms race between the United States and the Soviet Union. It has been reset 25 times since its creation.

Viewed as a visual representation to warn the global populace about multiple factors that could negatively affect the planet, the clock was last changed on January 24 and moved forward to 90 seconds to midnight—the closest to global catastrophe it has ever been. The reasoning cited the Russia-Ukraine war that, as of this February, will have lasted for two years and has led to nuclear threats from Russia.

Scientists uncover the secret to building Star Wars-style laser weapons — but don’t worry, we won’t have a Death Star anytime soon

Posted by in category: military

Today’s infrared lasers are only powerful enough to disable aerial targets, but scientists now have the keys to building high-powered laser weaponry that can ‘melt’ distant targets.

Chinese brain warfare includes sleep weapons, thought control

Posted by in categories: biological, military, mobile phones, robotics/AI

I dont know about sleep weapons, it s possible probably. More concerning to me, i read a paper 20+ years back about cell towers and cell phone frequencies as a possible tool for mind control, some way connected to frequency of human brain.


China’s military is developing advanced psychological warfare and brain-influencing weapons as part of a new warfighting strategy, according to a report on People’s Liberation Army cognitive warfare.

The report, “Warfare in the Cognitive Age: NeuroStrike and the PLA’s Advanced Psychological Weapons and Tactics,” was published earlier this month by The CCP Biothreats Initiative, a research group.

L3Harris gets green light to produce 16 space-based hypersonic missile trackers

Posted by in categories: military, satellites

WASHINGTON — Defense contractor L3Harris announced Dec. 20 it has received approval from the Space Development Agency to move into production on 16 satellites designed to detect and monitor hypersonic missiles aimed at the U.S. or its allies.

L3Harris said its satellites cleared a critical design review and a production readiness review.

The Space Development Agency (SDA) is a U.S. Space Force organization building a layered network of satellites known as the Proliferated Warfighter Space Architecture. It includes a Transport Layer of interconnected communications satellites that will transmit data collected by the Tracking Layer of sensor satellites.

Space Force eyes a future of speed and agility in orbit

Posted by in categories: military, policy, robotics/AI, satellites, space

For its latest Hyperspace Challenge accelerator, the U.S. Space Force selected three startups specializing in satellite propulsion, picks reflecting the military’s growing interest in nimble satellites that can maneuver to outplay adversaries.

This marks a shift for the Pentagon, which traditionally has launched satellites into orbit and restricted their movements to conserve fuel. But with rivals fielding maneuverable spacecraft, U.S. officials are calling for a shift to “dynamic space operations,” enabled by autonomous refueling and other in-orbit services.

“Having the ability to refuel would really open new possibilities,” said John Plumb, assistant secretary of defense for space policy. He said the Pentagon is encouraged to see commercial companies developing technologies for in-orbit logistics that also have significant utility for the military.

America’s Shaky Semiconductor Supremacy Over China

Posted by in categories: government, humor, military, robotics/AI

Like China, the US sees AI as a key to both a military and economic power in the 21st century. Both Republicans and Democrats in DC are concerned about the rate of Chinese advancement. In fact, the running joke on Capitol Hill is that the only thing they can agree on is The Chinese Threat.

Toward this end, Congress recently passed The CHIPS Act and the Executive Branch has been implementing trade controls to deny technology that they believe are critical for developing AI in China. While this desire is rational, it is unlikely to work in the mid-to long-term, and it will only increase geopolitical tension.
