Xubuntu disconnects local private network after brief timeout
it flag

I have Xubuntu 20.04 running a robot over a private network (absolutely no wider internet connectivity). When I enable the network interface ("wired network 1") it works for a while, the networking icon spins as it tries to contact the DHCP server and then after perhaps 60 seconds the interface is disconnected.

I'd like to keep DHCP enabled (I'm not always using this computer to control the robot ...

How do you move Sosumi VM?
jo flag

Does anyone know how to successfully move the Sosumi virtual machine installed through snap?

I've tried a couple different simple things without success and it's impossible to search for the specific information through online search engines or Youtube.

I need to move it out of my home folder onto a separate hard drive because my SSD is small and I only use it for the OS.

Everything has worked well so far, except I cannot use the fingerprint scanner. Under the guide provided by Ubuntu I should have the option under Settings > Users > Enable fingerprint scanning.

curl option --ftp-methods - What's the difference in practice?
us flag

I was having some problem with downloading some ftp files using curl. In the curl manual, there are some methods of calling ftp links as follows:

  • multicwd

    curl does a single CWD operation for each path part in the given URL. For deep hierarchies this means very many commands. This is how RFC 1738 says it should be done. This is the default but the slowest behavior.

  • nocwd

    curl does no CWD at all. ...

Grub "Boot from previously booted" setting not working
cn flag

I am currently running Ubuntu 21.10 and Windows 10. I always set up my grub the way I want using the grub-customizer tool. Among other changes (which all worked), I set it up so that it boots from the last booted partition. This setting worked in 20.04, but now it does not. Instead, it always tries to boot in to Windows.

EDIT: Here is the contents of /etc/default/grub:

21.10 snap Firefox crashed tabs
jp flag

I recently updated my desktop to Ubuntu 21.10. This defaults to a snap version of Firefox, and while it is slower to start, I could live with that. But the real problem was that, several times a day, I would be told that I had a crashed tab, and this message was in all tabs (of which I only had 3 or 4). The message included a button to restore the tabs, and while this always worked, it was annoying. As  ...

How to access root privileges in terminal via KVM when passwords are disabled?
cn flag

I have locked myself out of my server it seems by screwing up my firewall rules. Luckily I have KVM access... However I have disabled passwords on the root user. I have access to one standard user.

Is it possible to be able to access my root user for this server? Pass the public key in somehow? (clutching at straws!!)

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.
