[LXD]Lvm thin snapshot shipping support for lvm storagepool move
mh flag

As i understand with Zfs lxd storagepool move is fast ( as no rsync is involved) as things can be moved from different Zfs Storage pools via snapshot diff.

However no clarity is there for lvm thin snapshot shipping i.e using https://github.com/LINBIT/thin-send-recv OR a slower rsync shall be used(In scenerio where both side pools is lvm thin only)

I am trying to connect a SONY TV as a monitor to my Ubuntu (18.04) laptop through a VGA (input) to HDMI (output) converter. But this display is not detected in Settings -> Display.

But if I select "play on TV" from youtube, the video is played on the TV screen.

Is it not possible to use a TV as a monitor? How do I use it as a mirror screen?

Hardware (usb ethernet, wifi) cannot be used when a fresh installation and update using Ubuntu 22.04 LTS

the default kernel is 5.19.0-32-generic, and a fresh installation of ubuntu 22.04 LTS made it successful to be used, both the usb ethernet and the usb wifi (netgear A6210).

Until I installed the nvidia-driver, the kernel was updated to 5.19.0-50-generic, and even "apt-mark" the hold the kernel version didn't help.

So, the phenomenon is the original hardware cannot work on a newly updated kernel.

tar skip trying to compress files by extension

I noticed when compressing a directory with tar+gzip that the compressor was spending a lot of time trying to compress mp4 video files in vain. This makes me wonder: does gzip or any other common compression format (ex. zip, 7z, xz) support skipping compressing files (but still including them uncompressed in the archive) by extension?

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.
