From dangerous tunnels in Congo to consumers’ mobile tech

The sun was rising over one of the richest mineral deposits on Earth, in one of the poorest countries, as Sidiki Mayamba got ready for work.

Mayamba is a cobalt miner. And the red-dirt savanna stretching outside his door contains such an astonishing wealth of cobalt and other minerals that a geologist once described it as a “scandale geologique.”

This remote landscape in southern Africa lies at the heart of the world’s mad scramble for cheap cobalt, a mineral essential to the rechargeable lithium-ion batteries that power smartphones, laptops and electric vehicles made by companies such as Apple, Samsung and major automakers.

But Mayamba, 35, knew nothing about his role in this sprawling global supply chain. He grabbed his metal shovel and broken-headed hammer from a corner of the room he shares with his wife and child. He pulled on a dust-stained jacket. A proud man, he likes to wear a button-down shirt even to mine. And he planned to

LinkedIn sued over allegation it secretly reads Apple users’ clipboard content

Microsoft Corp’s LinkedIn was sued by a New York-based iPhone user on Friday for allegedly reading and diverting users’ sensitive content from Apple Inc’s Universal Clipboard application. According to Apple’s website, Universal Clipboard allows users to copy text, images, photos, and videos on one Apple device and then paste the content onto another Apple device. According to the lawsuit filed in San Francisco federal court by Adam Bauer, LinkedIn reads the Clipboard information without notifying the user. According to media reports from last week, 53 apps including TikTok and LinkedIn were reported to be reading users’ Universal Clipboard content, after Apple’s latest privacy feature started alerting users whenever the clipboard was accessed with a banner saying “pasted from Messages.” According to the complaint, LinkedIn has not only been spying on its users, it has been spying on their nearby computers and other devices, and it has been circumventing Apple’s Universal Clipboard timeout.

postmarketOS now boots on over 200 phones and tablets

In its first three years of life, postmarketOS has gotten considerable popularity over time, partly thanks to the rising interest in the field after the huge press coverage of projects like the Librem 5 and the PinePhone, partly thanks to its wide range of supported devices and extremely easy porting process, which made running Linux on most phones a breeze. The news is that postmarketOS just reached the milestone of 200 booting devices, which is a somewhat incredible achievement considering the aura of mystery Linux on phones and other ARM devices had until years (if not months) ago.

Blue light from digital devices speeds blindness

Blue light from digital devices and the sun transforms vital molecules in the eye’s retina into cell killers, according to optical chemistry research at The University of Toledo. Photoreceptor cells in the retina need molecules called retinal to sense light and trigger a cascade of signaling to the brain. You need a continuous supply of retinal molecules if you want to see. blue light exposure causes retinal to trigger reactions that generate poisonous chemical molecules in photoreceptor cells. It’s toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves. Photoreceptor cells do not regenerate in the eye.

does all blue light has this problem? if we live in a blue painted house does it affect our eyes? please stop using digital equipments in dark.
