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.
