I can't boot up windows after dual boot

So, I installed Ubuntu successfully with dual boot after a couple of installations due to corrupt iso, I should also add that I did make a separate partition and installed Ubuntu there after formatting it and used for boot loader the same as windows, which note was NTFS not EFI (if it's called that). So, it loads up grub as expected and then I get the option to boot either windows or Ubuntu. So, if I se ...

I am running a virtualized Ubuntu Server 20.4 (Hyper-V).

So I found a ton of tutorials, however none of them works. The bridge does not obtain an IP, and after a restart ...

What are directory permission conventions?
in flag

Running command ls -l / shows permissions of directories on my server.

I noticed that most directories are set to 755 or rwxr-xr-x, link bin and directories lib, lib32, lib64, libx32 are set to 777 or rwxrwxrwx.

/tmp uses a sticky bit but others don't. Are the other permissions a security risk? What are conventions regarding these permissions?

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.
