2019/01/29: Stingrays (AKA IMSI catchers) are a widespread class of surveillance devices that target cellular phones by impersonating cellular towers to them (they're also called "cell-site simulators").
IMSI catchers are so easy to build and operate that they have leapt from police agencies to criminals, and foreign and corporate spies, exposing us all to potential surveillance from all quarters.
That's why it was so important that the new 5G mobile protocol be designed to foil IMSI catchers, and why the 3rd Generation Partnership Project, or 3GPP (the body standardizing 5G) updated the Authentication and Key Agreement (AKA) to resist IMSI catching techniques.
But new research from ETH Zurich and Technische Universität Berlin has revealed a critical flaw in AKA, a defect that not only allows attackers to track the number of calls and texts being sent while a user is connected to the fake tower, but also a count of calls and texts from before the device was compromised. More importantly, the attack allows for fine-grained location tracking.
2018/10/10: In Edna Mall on the bustling Bole Road in Addis Ababa, the capital of Ethiopia, Mesert Baru poses for her Tecno Camon i. "This phone is seriously nice for selfies," says the 35-year-old shop assistant, admiring the picture she just took.
Mesert's satisfaction is no accident. Tecno cameras have been optimized for African complexions, explains Arif Chowdhury, vice president of Transsion. "Our cameras adjust more light for darker skin, so the photograph is more beautiful," he says. "That's one of the reasons we've become successful."
More innovations followed. Transsion opened research and development centers in China, Nigeria and Kenya to work out how to better appeal to African users. Local languages such as Amharic, Hausa and Swahili were added to keyboards and phones were given a longer battery life.
Chinese companies have been eager to use technology to tap into Africans' spending habits. In 2015, Kenyan mobile payments operator M-Pesa migrated all of its 12.8 million subscribers to Huawei's Mobile Money platform as it expanded across East Africa and beyond. The move increased the number of transactions M-Pesa could process, and the app's user base has more than doubled since then.
For Transsion, future growth is set to come from building its business outside Africa in other developing markets, such as Russia, Indonesia and Bangladesh. In 2017, it launched Tecno in India and within a year had claimed 5% of the huge market, according to IDC.
How did Tecno make such rapid progress? Transsion's Chowdhury says another innovation tailored to local customs has helped.
"Indian people use their hands to eat food," he says, "so their fingers get oily. What if you're having lunch and your boss calls? You try to take the call but your fingerprint won't work." The fix: screens that can read greasy fingers.
2018/09/19: Ten years from now, we might look back at the emergence of social media as a part of humanity’s growing-up – a time that created social divisions, anxiety and restlessness and which damaged the health and well-being of many. Until then, maybe it’s best to put our smartphones down – or at least switch them off a little more often.
2018/09/19: Notifications are no longer used to notify you of anything—they’re used by apps to beg for attention.
Facebook appears to be increasingly sending meaningless notifications to people who use the site less and less in hopes of enticing them back to it.
Twitter, a platform where literally anyone on Earth can pick a fight with you at any time of day and deliver it directly to your phone’s lock screen.
Doctorow: I have trained all the people who can send me messages using those protocols that the only time to send me a message over them is when something is extremely time-sensitive. I check in on everything else (email, Twitter mentions, etc) several times a day, but I don't have anything, on any of my devices, that interrupts me to tell me that someone, somewhere is thinking about me.
2018/09/10: American Indian/Alaskan, Hispanic/Latino, and African American students had the least access. White and Asian students had the most. Nearly a quarter of students who reported that family income was less that $36,000 a year had access to only a single device at home, mostly a smartphone: a 19% gap compared to students whose family income was more than $100,000.
DRC produces roughly two thirds of the world's cobalt, whose price has soared by 180% in the past three years. On paper, this would mean that DRC is sitting on a gold mine, but the reality is slightly different. On the one hand, experts talk about supply shortage. But even more disturbing is the link between cobalt mining and child labor.
Children like Lukasa, 15, who begins his 12-hour shift at the mine at 5 a.m. every day. He walks for two hours to the mining site, before spending eight hours mining this grayish metal that keeps our phones (and lives) moving. On a good day, he makes $9. Little does he know about the multibillion-dollar scramble underway.
The demand for cobalt has only just begun. Cobalt is also crucial for the global transition to renewables. Each electric car will need over 1,000 times the amount of cobalt a smartphone does.
Companies and NGOs are far from finding a solution that would end child labor without taking away from thousands of families their only source of income. Some argue thatblockchain could be the solution.

I see three parallel developments that I predict will kill the phone companies as we know them. The first is the shift to mobile handsets. Landlines are disappearing for good. The second is the political pressure to make internet connectivity a basic urban utility, like streetlighting. The third is the handsets’ increasing ability to place voice calls directly over the internet, bypassing the telco network altogether.
