I am trying to create a private network of VMs and containers on Hetzner Cloud. I've tested this setup on my local home network and all works fine.

The plan is to have a private network for the VMs (10.0.0.0/8 just for testing). For my test I am using 10.10.0.1 and 10.10.0.2 as VMs. And each VM, will have a CNI bridge network, (eg: 172.20.0.0/16, for container). I want to make the bridge networks a ...

I am currently using a Git-Repository setup with Gitlab on a cloud server and accessing it with a public IP provided by the vendor.

However as the files stored in the Git repository get big, a lot of network disconnection issues occur causing the git pull/push operations to fail after waiting for a long time.

Where are SMB ACL's stored when using AD with Solaris ZFS?
jp flag

I have a Solaris 11.4 instance bound to a 2012 Domain.

Solaris allows you to edit SMB share ACL's from a Windows DC via the Computer Management Snap-in.

My question is: Are those ACL's then written back to the Solaris instance, or are they only stored on the DC which then provides some kind of token to an SMB client to connect to the Solaris SMB share?

I am playing with Open-iSCSI and came across some troubles. When the network link between my initiator and the target fails, iscsid will recover the connection, which is good. But my mount is broken and yields I/O error until it is remounted.

Is there a clean solution to remount the lun automatically? Something like a hook on post recovery or a config setting that I somehow missed? I am trying to  ...

Can I remove a disk from a ZFS stripe?
me flag

I have a large pool on a system. The system is a storage node in a Hadoop cluster, so a stripe is fine because if we lose the local pool we can reconstruct the data at the cluster level.

A disk is going bad: can I tell ZFS to try and move the storage blocks off the device so I can remove it, or do I need to delete the entire pool and rebuild it? Ideally, I can pull the disk out, and later add a n ...

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.
