How to make captive portal forget my laptop so I can sign in again?
tr flag

I'm at a hotel and have wifi; I signed in with the usual captive portal kind of setup for the hotel's free wifi tier.

I later got a code for their premium wifi -- but I can't seem to retrigger the captive portal so I can get the network to put me on the premium tier.

Is there anything I can do to make the network forget my computer and go through the captive portal again? Since initial sign-in, I ha ...

Black screen between plymouth and lightdm
au flag
jdm

I am using Ubuntu 18.04 on a custom ARM-based board. When it boots, I see the plymouth boot screen for two seconds, and then it jumps to a console screen with a blinking text cursor in the upper right for about five seconds, before X11 loads.

I checked systemd-analyze, and it does run plymouth-quit-wait.service immediately before starting lightdm. However, it is lightdm itself that shows the blac ...

I've inherited a WordPress 5.7 site running on an Ubuntu 16.04.3 x64 droplet, which uses a separate DigitalOcean managed MySQL 8 database.

The WordPress site is a Trellis LEMP stack site. PHP version 7.3, but Nginx seems to be using 7.1 from a phpinfo().

I'm aware that all the versions are seriously outdated and need updating, but in the very immediate term I need to first get things working.

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
