Gtk-WARNING **: Could not load a pixbuf from icon theme
pt flag

Whenever I start firefox, steam, and some other gui programs from the terminal, I see this error.

I have searched for possible solutions to this problem, the most common one I found was sudo update-mime-database /usr/share/mime, which runs without printing any errors (or anything at all) for me, but does not change anything.

I tried changing permissions, as suggested here: How to repair broken permissi ...

I have created a rule that should block traffic from all IP addresses except from my IP address. At leased so I thought but it does not block the traffic. I can still access both SSH and 16000 from any IP address. What am I doing wrong here?

x-terminal-emulator font rendering
mx flag

Ubuntu comes with x-terminal-emulator alias "termit" (not "termite"). I've read the manual pages and examples, but can't figure out how to make fonts look good.

I'm specifying a user config in ~/.config/termit/rc.lua, as it is standard and also detailed in the manual page for x-terminal-emulator.

The fonts I've tested are all under /usr/share/fonts/truetype/<fontFolder>/<fontName>. For examp ...

Live boot, casper-rw issue

I created a live bootable USB for Ubuntu through Rufus 3.14 on Windows 10. I used the persistent storage available there and after booting into Ubuntu, I see a disk partition casper-rw present but I am unable to store anything there or interact with it. Do I need to mount it or do anything else to make it usable?

How do I set the dash-to-dock width?
us flag

In Ubuntu 21.04, I can set the dash-max-icon-size to something smaller than the default 48. This shrinks the icons, and the vertical space occupied by each icon. However, it does not shrink the width of the dock, leaving a lot of blank space on the left and right of each icon in the dock. Is there a way to shrink the dock width to match the icons in the dash?

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.
