Each week, I receive tons of questions from my listeners about tech concerns, new products and all things digital. Sometimes, choosing the most interesting questions to highlight is the best part of my job. This week, I received questions about old computers, fake videos, Jeff Bezos' phone and more.

From your water-logged phone to your smashed smart TV, those personal electronics headed for the landfill are a potential goldmine. Economists already knew that along with the swelling 44.7 million metric tons of electronic waste tossed each year we were throwing out billions of dollars in resources. But quantifying all the gold, copper, iron, plastic, and rare earths languishing in our landfills and recycling centers is only part of the problem. Figuring out whether it's worthwhile, financially speaking, to sift those resources out of the rubble--instead of continuing to extract them from traditional mines--is another issue entirely. A study published in Environmental Science & Technology this week finally has an answer, suggesting that'urban mining' of electronic waste for copper and gold in China was actually more cost-effective than digging those metals out of the ground.

Two Ohio inmates used discarded computers to access their prison's network to create passes to get into restricted areas and plan a tax fraud scheme. A state watchdog released a report on Tuesday stating a lack of supervision at the Marion Correctional Institution allowed the prisoners to hide computers in the ceiling and run wiring to connect them to the network. The two tech-savvy convicts were also able to access the internal records of other inmates as part of their scheme. One of the prisoners planned to steal the identity of a fellow inmate and file tax returns under that inmate's name, officials said.

Roughly 20 km away from Hong Kong's slick, densely packed urban center lies the New Territories -- a suburban mishmash of rugged hills and scruffy villages, soaring new housing developments and vacant lots. This is where over half of the territory's 7.2 million people live. It could also be the resting place for your old PC or printer. Up to 20% of all U.S. electronic waste may be ending up in Hong Kong. Not in some scrapyard in the developing world, picked over by haggard children and wheezing laborers, but in the backyard of one of the world's most sophisticated financial capitals.

A new report from the Government Accountability Office found that federal agencies waste money by maintaining rather than updating outdated computer systems. WASHINGTON -- The government is squandering its technology budget maintaining museum-ready computer systems in critical areas from nuclear weapons to Social Security. In a report released Wednesday, nonpartisan congressional investigators found that about three-fourths of the 80 billion budget goes to keep aging technology running, and the increasing cost is shortchanging modernization. The White House has been pushing to replace workhorse systems that date back more than 50 years in some cases. But the government is expected to spend 7 billion less on modernization in 2017 than in 2010, said the Government Accountability Office.
