Ubuntu 23.04: Window with VSCode (and other apps) never starts maximized

It seems to be a regression in 23.04. It worked for me in 22.10. Then I upgraded to 23.04 and the issue arised.

When I start VSCode, its window is never maximized though I maximized it last time before I closed it. Also other applications (e.g. Skype) are affected.

Is there a new way how to force persistent maximized window of an application in Ubuntu 23.04?

I installed Ubuntu 22.10/Kinetic with the ZFS filesystem option. I would like to upgrade to 23.04/Lunar but am concerned about whether the system will be bootable after upgrade due to lagging ZFS kernel support.

My understanding is that Lunar jumps to Kernel 6.2 but ZFS just added Kernel 6.2 support. It doesn't look like Ubuntu ZFS was updated in time to be included in the release.

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.
