R processes stuck in memory from last Jupyter in VS Code session
vn flag

I have noticed that I often will have multiple R processes still running, and occupying a significant amount of RAM, even if I closed all applications that I use for R.

For the most part I use VS Code with the Jupyter extension, and based on the commands running (below) the lingering R sessions are seemingly remnants of the last Jupyter session in VS Code. (I open RStudio or JupyterLab from time  ...

Synaptics touchpad settings from xorg.conf are not applied
id flag

I can't set options for my touchpad's synaptics driver. Sorry if this looks like a duplicate but I tried solutions from other questions and none worked. I focused on doing it the 'right way' so using a separate conf file in /etc. The laptop is ThinkPad T480, Ubuntu 20.04.3.

I tried using files:

/etc/X11/xorg.conf
/etc/X11/xorg.conf.d/synaptics.conf
/etc/X11/xorg.conf.d/70-synaptics.conf
/etc/X11/xorg. ...

External USB disk I/O error after sleep/wake
my flag

I have a 1TB Toshiba USB HDD connected to the USB 3.0 port in my laptop (Asus X550C). I am using Ubuntu 18.04 (kernel 4.15.0-166-generic).

I used to sleep/wake up the computer with the USB drive attached and everything resumed normally. However, since one Ubuntu update (I cannot tell which one) I get I/O errors from the USB disk after waking up:

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.
