BARCELONA–I’m here for my third Mobile World Congress. My major discovery so far this time around: I should have flown out Friday evening, so that I could get the falling-asleep-on-the-train phase of jet lag out of the way before the wireless show’s press events kick off.

This post is short this week, on account of my USAT column not having been posted yet. I e-mailed my editor earlier tonight to ask if it got lost in production but haven’t heard back. Update, 3/1: And there it is.

2/24/15: Superfish and the Sordid History of Selling Customers’ Online Privacy Out From Under Them, Yahoo Tech

This column came together more easily than most: My mental outline of the story stayed relatively constant. And yet I still wrestled with the concluding sentence for a good half-hour or so.

3/1/2015: Ease Mac migration with OS X net sharing, USA Today

This was yet another tech-support workaround I learned during my holiday stay with my in-laws–making that the most productive visit yet in terms of generating USAT column material.
