starting out w/ rdiff-backup, having permissions issues
jp flag

I have 2 machines - SERVER and BACKUP. On SERVER I have a script that backs up a few directories and databases, ending up in /var/local/backup with permissions intact (ownership is root and www-data on all of the files).

I'd like to use rdiff-backup on BACKUP to retrieve the contents of /var/local/backup on SERVER and sync it to, for example, /var/local/backup on BACKUP.

Memory consumed quickly on my server
cn flag

Recently I notice the memory on my Linux server(CentOS 6.8) is consumed quickly. Yesterday I restart my server, and then use free to check the memory, and it reports about 30GB free among 32GB memory.

However, after one day, the free memory is reduced to 12GB.

Is that normal?

I try to use top -a command and get the following result:

How do I get logs from my dropbear-initramfs SSH host?
jp flag

I use dropbear-initramfs (like this) to decrypt the root drive on my Ubuntu 20.04.3 headless server. Recently the server was abruptly powered off (power went out I think?) and now the dropbear SSH server rejects my public key.

I can successfully connect a keyboard and monitor and type in my decryption key, and I can reach the full SSH server after that, but then I still have the same issue with the publ ...

Cannot access my website with the custom domain name when using VPN

Hyper-v - VM state merging
il flag

Recently I started to get issues with "VM state merging" in my Cluster (Cluster, 6 nodes, WS2016).
The problem is - I can't change the status. Poweroff, shutdown, reset, live migration, nothing helps. Only hard-restart the node!
It looks like hyper-v services don't show the state correctly and don’t work correctly either.

The only way for me to solve the problem at this moment is to poweroff all  ...

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.
