This week involved a large tech conference, but I didn’t have to go any farther than D.C. for it: Microsoft Inspire ran from Monday to Wednesday at the convention center, with the morning keynotes held at the Verizon Center. The event yielded one post, an idea for another and a sweaty evening at Nationals Park Wednesday, the location of the Carrie Underwood concert that closed out the gathering.

7/10/2017: Virgin Mobile’s iPhone-only plan: What’s the catch?, USA Today

This snakebit column required not one but two corrections. The first remedied my mistake in reading “$1” as this Sprint prepaid brand’s promotional monthly rate when it was the cost for the entire first year of service; minutes later, I saw a reader comment calling out my dumb error in writing “megabits per second” instead of “kilobits per second” when describing a streaming speed limit.

7/12/2017: Microsoft reveals two big ways to stop ransomware attacks, Yahoo Finance

Microsoft president and chief legal officer Brad Smith’s keynote Wednesday called for collective action to stop ransomware and other malware outbreaks. But getting companies and organizations to end their long-running abusive relationship with Windows XP won’t be easy; neither will persuading governments to stop hoarding vulnerabilities in favor of promptly disclosing all of them so they can be fixed.

7/12/2017: Working with Tech Media in the Washington D.C. Region, Washington Network Group

I spoke on this panel with the Washington Business Journal’s Andy Medici and FedScoop’s Tajha Chappellet-Lanier (a fellow Washingtonian Tech Titan honoree) about coverage priorities, tech trends and PR pet peeves. Once again, I implored publicists not to follow up by re-sending the original e-mail topped by nothing more than “Any interest?”

7/14/2017: Sprint doesn’t want you to buy your next phone, Yahoo Finance

Sprint gave me an advance on this, but its PR pitch for its new Flex leasing deal didn’t spell out that this move would also end Sprint’s installment-payment pricing on phones. Because I’m slow, I needed a couple of rounds of Q&A to grasp that difference. Sprint, in turn, didn’t clarify the international-unlocking policy under Flex until Friday morning, after its embargo on the news had passed but before it had posted its own press release.

7/14/2017: How a system meant to keep your money safe could put it in danger, Yahoo Finance

I expected to see everybody else jump on this story of a PayPal customer losing money after an AT&T rep let an unknown attacker move his number–the last line of defense on his PayPal account–to a new SIM, since I learned about it on Twitter a week earlier. Instead, I had time to quiz PayPal, AT&T and others; verify that a no-longer-advertised phone-free form of two-factor authentication still worked at PayPal; and have an enlightening chat with Google security product manager Stephan Somogyi about the tradeoffs of different “2FA” methods.
