Comment Trying wine 2003 (Score 1) 14

Walmart's been trying to get suppliers to RFID stuff since their 2003 RFID mandate, which demanded suppliers tag pallets and cases by 2005, but s pretty much failed out of the gate due to exorbitant tag costs, unreliable technology, and supplier pushback, resulting in only partial compliance and a scaled-back approach by 2006. They really pushed for UHF EPC backscatter tag standardisation. But UHF is PITA. It can reflect off surfaces, not penetrate to cartons inside pallets with metal and water.

But.. they keep persisting. Interesting to they are trying BT now. Apparently the wiling tags scavenge RF to power their BT transceivers.

Here’s an AI summary.

Walmart’s battery-free Bluetooth Low Energy (BLE) tags, like Wiliot’s pixels, harvest ambient RF energy (e.g., from Wi-Fi or RFID readers) using a small antenna and efficient rectifier, capturing 2.5-50 W in retail environments to charge a capacitor for brief BLE transmissions that consume ~9 J per packet. Ultra-low-power chips with duty cycling and simplified protocols enable 3-5 mA bursts lasting milliseconds, broadcasting minimal data (e.g., ID or location) over 1-10 meters every few seconds, with Walmart’s strategic placement of BLE gateways and RFID readers ensuring sufficient RF energy for reliable operation in stores and distribution centers.

Ok, I’m getting old.
I’ve noticed the decay of logical thought process from politicians especially over the last 10 years.
For example, in Victoria Australia, the state government just paid a small fortune to place dozens of Machete amnesty bins around the city. I honestly thought it was an AI joke, yet they can’t afford to replace rural fire trucks.
As an engineer, it’s infuriating how ideology increasingly rules over logical thought process, and in the case of this article, complete nonsense makes its way into the public discourse.

Comment I watched it. (Score 3, Interesting) 49

Normally I read the reviews of any movie, but last Friday night I watched this in our little home cinema with my wife without checking.
First, it helps if you have ADD to watch this as the social media interaction is fast and furious. It’s really an ode to how over connected we are.
It was full of product placements for Amazon and Microsoft. I’m not sure if any scene had more than one actor on a screen at a time. It was like a work from home acting experience. The military scenes were library footage. The focus of IceCube on his kids was an annoying plot device, so we skipped a lot of those bits.
The metaphor of the aliens wanting suck up our data to destroy us was ironic given AI and were we heading.
Eva was looking good for her age and we did make it to the end.
I give it 3/10.
