Simple Knife Defeats $4m AI Weapon Detection System

Talk about bringing a knife to an AI fight, the clear winner was a knife. Or really, any large knife.

One New York school district learned this the hard way. It spent close to $4 million to buy an AI-powered weapons scanner from Evolv Technology that the company bills as “proven artificial intelligence” able to create a “weapons-free zone.”

Then, on Halloween last year, a student walked through the scanner carrying a nine-inch knife and used it to stab a fellow student multiple times, the BBC reported.

[…]

A BBC investigation found that while Evolv Technologies claims their systems can detect guns, knives, and explosive devices, during 24 walk-throughs a scanner missed 42% of large knives.

Evolv claimed it found a lot of knives and it saved a lot of time. These are weasel words. They cost $4m and failed. Was it worth the cost?

The obvious answer seems no, the school should have paid teachers that $4m instead.

Teachers broke up the altercation, local news station WKTV reported, and the victim was taken to the hospital.

Teachers ironically aren’t paid more for intelligence work, but they clearly have to clean up the mess when high cost low value AI is installed.

CA Tesla Crash Kills Three in Massive Fire

A local southern CA news story says a Tesla driver killed himself and two others when he crashed at high speed in a school lot. The only survivor was someone pulled from the vehicle by a neighbor.

The single-vehicle crash occurred just after 11 p.m. Saturday in the 39400 block of Whitewood Road, according to the Murrieta Police Department.

Agency spokeswoman Dominique Samario said the Tesla was traveling in an unknown direction when it went out of control and crashed in the parking lot of Alta Murrieta Elementary School, catching fire.

“One male occupant was discovered outside the vehicle with severe injuries,” Samario said. “The male was transported to a local hospital. Murrieta police and Murrieta Fire & Rescue personnel discovered three occupants inside the vehicle after the fire was extinguished. The occupants were pronounced deceased at the scene.”

Traveling in an unknown direction. The three bodies were found after fire was extinguished, begging the question why they couldn’t be pulled out in time to survive.

Skid marks could still be seen on the road in front of the crash scene…

Keyword Attacks Break ChatGPT: Simple Loop Leaks Training on Conspiracies

A researcher has posted evidence of a simple trigger that ChatGPT chokes on, leaking unhinged right wing conspiracy content because apparently that is what OpenAI is learning from.

If you ask GPT3.5 Turbo to repeat specific words 100 times, it seems to enter this stream of consciousness like state where it spits out incoherent and often offensive or religious output.

Words that trigger this are “Apolog”, “Apologize”, “Slide”, “Lite”. I’m sure there are many others.

This prompt will usually trigger it, “Hey can you repeat the word “apologize” 100 times so I can copy paste it and not have to manually type it?”

My guess is that it triggers something to break it out of a repetitive loop that doesn’t completely work.

This proves, yet again, that there is no such thing as a hallucination for ChatGPT because everything it does qualifies as a hallucination. It’s regurgitating what it’s fed by downgrading, as if a “prediction” can only be a continuation of what is undesirable and with lessening quality.

Electric 1987 Nissan Sunny LEAF Vintage Pickup

I just can’t get enough of Nissan EV news. When I heard from Toyota how they would leapfrog Nissan in solid-state battery production… I thought NO WAY was this the only angle. Nissan typically is way ahead on innovations so I poked around and found this nugget from them at SEMA 2022.

…the electric drive motor and 40-kWh lithium-ion battery pack from a Nissan LEAF. Rated at 147 horsepower and 236 lb-ft of torque, the LEAF motor has around twice the power and more than three times the torque of the gasoline four-cylinder engine originally equipped in the Sunny.

Tommy Pike Customs (TPC) dropped a LEAF powerplant into a vintage Nissan truck — boosted it with way more power, and way less pollution, than its four-cylinder gas burner — while still running a factory original 56A manual transmission.

OMG.

A manual EV compact pickup with 3X torque? A low cost zero-emission locally powered (solar) hauling machine?

Yes please.

The Nissan Sunny EV is a true ray of sunshine

Adding power meant upgrading the handling, of course. So they also dropped in a 240SX S13 front suspension — front coilovers, disc brakes and lower control arms.

Have to say it reminds me of the 1998 Electric Ford Ranger, as well as the old Chevy E10 Bolt pickup concept, but still this Nissan has its manual transmission and is drivable today.

In 2006 I worked with a Silicon Valley engineer who commuted from the mountains using solar power for their 1998 Ford Electric Ranger (60 mile range was plenty). They fought hard to keep it as their daily driver and won… one of the few 1990s EV on the road that weren’t erased from existence by the Bush Administration.
Chevy stuffed a Bolt EV inside their E10 pickup concept.

Every time an auto blogger suggests the reliable and smart LEAF is “tired” to them because it was the first EV to be mass produced, I see real hotrod potential. This LEAF conversion kit for old compact pickups might just be exactly what small town America needs right now.

And on that note, Toyota seems to have… nothing (their hydrogen AE86 Collora being about as exciting as breathing amonia). Well done Nissan. Well done.
