Weekly output: smartphone biometric security, Google vs. the headphone jack, Voatz blockchain absentee voting

Once again, Columbus Day–or, if you prefer, Indigenous People’s Day–delivered the unwelcome combination of our kid’s school being closed while both my wife and I still had to work. I joked on Twitter about resolving the argument over what to call this fake holiday and also saving Americans billions in day-care costs by abolishing it outright. But on reflection, the widely-tweeted suggestion that we relegate Columbus Day to a trivia question and promote Election Day to actual, don’t-have-to-work holiday status makes much more sense.

10/8/2018: Unlock your phone with your face or fingerprint? Here’s how to shut that off – quickly, This Morning With Gordon Deal

I talked about the subject of my most recent USA Today column on this business-news radio show.

10/10/2018: With Google’s new devices, music fans once again don’t get jack, Yahoo Finance

I’ve had this post in mind for a while, ever since conversations at events like Mobile World Congress and IFA revealed their lack of interest in shipping USB-C headphones. I expected that Google wouldn’t retreat from last year’s idiotic move to remove the headphone jack from its flagship smartphones, but I didn’t realize they would pull the same stunt with the new Pixel Slate tablet.

10/11/2018: This startup wants to secure absentee voting with a blockchain, Yahoo Finance

Even after spending a couple of weeks talking to various experts, I still have questions about how Voatz has been securing its blockchain-based voting system and whether states have thought long enough about how to ease absentee voting for faraway citizens. That said, many of the other options for absentee voting look even worse, something upon which I hope to write further in the coming weeks.

Weekly output: hotspot data use, smart grids, 3D printing, quantum computing, Sheryl Sandberg

After clocking almost 24,000 miles in the air in a 12-day period, I’m not scheduled to fly anywhere until late July–and that time, I’m taking my family. This week’s trip was to Paris for the second installment of moderating panels at the Viva Technology conference (with a side order of meetings with local tech types set up by a PR firm hired by Business France, the government trade-promotion organization that paid for my airfare and lodging), and the flights seemed positively short after last week’s jaunt to Shanghai and back.

6/14/2017: Use a mobile hotspot? How to avoid busting data caps, USA Today

I heard from a reader who said he’d successfully dropped his residential broadband connection in favor of tethering off his phone; I worried he’d exceed his wireless plan’s cap on mobile-hotspot use, so I wrote this how-to. It ran in the paper’s print edition Friday.

6/15/2017: Smart Grids Are Getting Smarter, Viva Technology

My conversation with LO3 Energy’s Scott Kessler and Upside Energy’s Graham Oakes involved some unexpected difficulty: I woke up around 3:30 in the morning and couldn’t get back to sleep for the next two hours. I haven’t had jet lag that bad in Europe in a couple of years, but spending the previous week six time zones to the right (or 18 to the left, depending on how you look at it) could not have helped.

6/15/2017: How Industrial​ ​3D​ ​Printing Is Helping Startups Go from Zero to Factory​, Viva Technology

Having his panel with Product of Things’ Moriya Kassis and re:3D’s Samantha Snabes come almost right after the other meant I didn’t have a chance to realize my fatigue again. Afterwards, I thought I could get in a nap in the speakers’ lounge–but French president Emmanuel Macron’s visit there made that impossible. (My Yahoo writeup of the pro-startup agenda Macron talked up in his Viva Tech speech should post Monday morning.)

6/16/2017: Quantum Computing, Cryptography And Our Privacy, Viva Technology

I felt like less of a zombie for this chat with Kudelski Security’s Jean-Philippe Aumasson and Shlomi Dolev of the wonderfully-named Secret Double Octopus. And I learned a few things about quantum computing in the process, which is how a panel is supposed to work.

6/18/2017: Sheryl Sandberg has 2 useful pieces of advice for Facebook advertisers, Yahoo Finance

Facebook’s chief operating officer spoke by video to Viva Tech co-founder Maurice Lévy at the end of Friday’s sessions, which made for some rotten timing in terms of my writing the story and then deal with edits. The lesson I take from that: It’s a privilege to be able to go to Paris for work.
