My server's disk space is full but I can't see where it comes from

When I enter df -H I've got this :

udev            997M     0  997M   0% /dev
tmpfs           203M  1.1M  202M   1% /run
/dev/sda1        21G   21G   76M 100% /

So the files that takes a lot of space is in /

but when I type ls -a -Ssl --block-size=k / I've got this :

Can I make my laptop work on full performance from battery?
cn flag

I need my laptop to work wirelessly (without charger plugged in) with several devices attached via USB (Arduino, lidar, camera, etc.), but when I unplug charger it automatically degrades performance.

I tried to install TLP and set TLP_DEFAULT_MODE=AC + TLP_PERSISTENT_DEFAULT=1, but it doesn't really help much. Is there any other tweaks I miss, or battery just can't handle that much power consump ...

How can I perform a secure automatic file transfer between two servers?
us flag

I would like to transfer some files from a server A to a server B daily (for backup purposes). However, I cannot find a way that does not create security breaches. My goal is that someone with sudo rights on server A cannot exploit this transfer to connect to server B.

My base idea was to do a cronjob with a scp (or similar) command in it. Obviously, using a password-based SSH connection between A and B ...

I have Ubuntu 21.10. and after 1 month, I'm experiencing unresponsive keyboard or keys doing something different to what it's meant to.

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.
