How do I reset a PowerShell build step script to use the template?
cn flag

I have a build script template that does all the usual build script things: sets up a bunch of parameters, configures various config values, and runs a PowerShell script to run a build step. This template is inherited by a handful of build steps that customize things for different code branches.

TeamCity allows values from the template to be overridden in the inherited build steps. In the case  ...

backup /home over sftp - root

My current task is to set up a (remote) backup (using rsync/rsnapshot) over sftp of /home (linux). Obviously some files are read only for the owner (ie -r-------; and should stay that way) so i guess I'll need the root user to back up those files. Setting up an rsync daemon seems also too insecure to me.

However, I do hesitate to use an ssh key for that purpose due to security concerns (if the ba ...

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.
