In Openstack, is it possible to create compute nodes with no hard drives and use PXE in order to boot the host's system and therefore launch instances with no local drive which is needed to boot the VM's image.

If not what's the minimum storage needed to be given to hosts in order to get fully functional system.

1024 or 2048 bit keys for DKIM?
vn flag

Referencing this: https://crypto.stackexchange.com/questions/72297/recommended-key-size-for-dkim

What I get from this is (at the time) DNS providers (usually) allow for up to 1024 bit keys but not 2048 bit. Now, my provider does let me use 2048 and confirmed DKIM signs. Of course, the post claims 1024 is perfectly safe, but if I have the option to use 2048 I'd like to.

Am I good to go, so long as my  ...

Have to manually build RAID array every boot and cannot add third drive - MDADM

I have a RAID1 array that I've had to manually rebuild every time the system boots for a long time. Never had time to figure out why. This is the command I've been using to rebuild it every boot: sudo mdadm --build /dev/md0 --level=1 --raid-devices=2 /dev/sdb1 /dev/sde1

This works great and doesn't loose any data. I can then manually mount /dev/md0 where I need it (/mnt/plex in this case). However, I ju ...

Why the IP cannot be used directly when the IP mapped to the host name as a host entry works?
ru flag

I was given an API for a service through which I tried to send a post message from server A, but the connection cannot be built. Then I ping the domain name in the API. It doesn't work, so I thought it would be that the domain name had not been publicly mapped to the website.

To find the IP of the website, I pinged that in intranet from my client B, and then I used the IP shown in the message to  ...

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.
