Cannot reach some WEB pages
in flag

A few weeks ago I was able to browse any WEB page from FireFox on my Ubuntu 20.04 desktop system. Now some WEB pages time out. For example, no problem accessing askubuntu.com, but I time out trying to reach one of my own WEB pages hosted on GoDaddy (for example http://magic.kayaker.net/Terrain/). If I plug my Windows 10 laptop into my same LAN next to this Ubuntu system, the laptop can reach any WEB pag ...

How to set up simple SMTP and POP services on one host to send/receive email on that host for app demo purposes
gt flag

I have an application that can send and receive emails, however, I want to keep all communication within the one host as it is only for demonstrating the apps features. I guess I have to install SMTP and POP services but beyond that big picture I'm unsure how to proceed and how to do it so I don't have to become a email expert. I have done my googling but could not find anything appropriate. Any ideas o ...

How can I get alsamixergui to default to -c 1 and be able to open it with a shortcut (dock icon or desktop icon)
in flag

Ok, so I'm new to ubuntu and wanted to have audio output to both built-in laptop speakers and an external speaker which is plugged into the 3.5mm headphone jack. I discovered the terminal command "alsamixer" which allowed me to disable auto mute and manually unmute the built-in speakers. I then discovered "alsamixergui" which is a lot easier on the eyes but sadly it defaults to displaying the audio ca ...

Can't mount ext4 partition with write permissions
vn flag

I got a new computer, so I decided to scavenge the old one and use it's 240GiB SSD as my games partition. After I formatted and configured it, I can mount it (and it even auto mounts with fstab), but always as read-only.

I've read countless guides and answers, but all of them addresses ntfs partitions or some other problem with ext4 that I don't have.

These are the steps I used to format and configu ...

Automate move new files after a set period of time
br flag

I receive files though a service at odd intervals and need to have them available in one folder for 72 hours before being archived in a different folder. I would like to automate this process. Ideally this would be a service that watches the "in-use" folder for new files, notes the time of their arrival, then moves them to the archive 3 days later.

Why does my window or application minimize when its child process exists?

I am experiencing a strange issue with Ubuntu 18.04 that I don't know could have been caused by a wrong configuration or a conflict from recent application installs. What happened was whenever the child process of a GUI application exists, the parent GUI minimizes. Example cases would be:

Example 1:

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.
