  • Lumafield scanned 1,054 batteries – around 100 from each brand – and found 33 of them had a serious manufacturing defect known as negative anode overhang. The defect “significantly increases the risk of internal short-circuiting and battery fires” and can reduce the overall life of the battery,” according to Lumafield. All 33 of the batteries with the defects came from the 424 sold by low-cost brands or brands selling counterfeits…

    For two of the counterfeit brands that were reporting impossible specs, the percentage of tested batteries from those brands that were found to have the defect were even higher – upwards of 12 and 15 percent. None of the name brand OEM batteries were found to have any problems…

    Defects like negative anode overhang and bad edge alignment don’t mean an affected battery is guaranteed to explode or catch fire, but they can increase the risk of those incidents occurring, particularly when combined with other factors such as being left in a hot car or an accidental drop causing additional damage.



  • I hope the AI-chat companies really get a handle on this. They are making helpful sounding noises, but it’s hard to know how much they are prioritizing it.

    OpenAI has acknowledged that its existing guardrails work well in shorter conversations, but that they may become unreliable in lengthy interactions… The company also announced on Tuesday that it will try to improve the way ChatGPT responds to users exhibiting signs of “acute distress” by routing conversations showing such moments to its reasoning models, which the company says follow and apply safety guidelines more consistently.


  • I’ve occasionally been part of training hourly workers on software new to them. Having really, really detailed work instructions and walking through all the steps with themthe first time has helped me win over people who were initially really opposed to the products.

    My experience with salaried workers has been they are more likely to try new software on their own, but if they don’t have much flexible time they usually choose to keep doing the established less efficient routine over investing one-time learning curve and setup time to start a new more efficient routine. Myself included - I have for many years been aware of software my employer provides that would reduce the time spent on regular tasks, but I know the learning curve and setup is in the dozens of hours, and I haven’t carved out time to do that.

    So to answer the question, neither. The problem may be neither the software nor the users, but something else about the work environment.
