My main display is 34 inches @ 3440x1440, and the secondary is a 24 inch @ 3840x2160.

Installing and running mpack on a fresh ubuntu (Algo VPN) instance results in *** buffer overflow detected ***: terminated

I have created an Ubuntu 20.04.2 LTS instance via the Algo VPN scripts using google cloud. I SSH into the instance for the first time and execute the following simplified test case which results in mpack crashing. Unfortunately I am not overly familiar with c/linux debugging and crash analysis. Does anyone know how I would go about fixing this?

Desktop larger than the screen
br flag

The cat laid on the keyboard and when I got him off, the desktop was zoomed in so that to see all of it my mouse cursor automatically scrolls. What keys did he hit?

That was on Ubuntu 20.04 (Focal Fossa) using GNOME.

How do I boot up Ubuntu from USB boot drive on Windows 8?
in flag

I am using an old Dell laptop with Windows 8.1, and I have a USB boot drive with Ubuntu ready to go. I tried to change my BIOS boot settings to use the USB, but I cannot seem to get it to work. For some reason the BIOS is trying to use a specific file from the USB, and won't use the entire drive. It is an empty drive aside from the Ubuntu ISO files. How do I add the USB as a boot option?

After a hirsute upgrade, I found that my DNS and HTTP services were no longer working, though most everything else was. The error is Connection Refused. The processes are running successfully, in docker, but it seems as if the port bind is silently failing.

lsof reports that the ports are in use and listening. I've verified by connecting to the internal Docker IPs that the upstream services are running. ...

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.
