Lightest option for MySQL proxy
in flag

I'm looking for the most lightweight program that is capable of serving as a MySQL proxy to a remote server, unifying all connections to the proxy into a single connection to the remote MySQL server (so only the proxy will be on my machine).

I installed mysql-router but then, per this article from the docs, it seems it requires the normal MySQL server package, which I want to avoid completely (unless i ...

Ubuntu hangs and becomes unresponsive until reset

I hope I found the right place to ask for help.

I experience quite annoying behavior on my Ubuntu 20.04. Every few days, the system becomes suddenly unresponsive until I hit the reset button (raising elephants is so utterly boring also helps). And I cannot track the issue down. Here is the /var/log/syslog at the crash time:

I've already installed Ubuntu 20.04, but I did not make any separate partitions beside the one the operating system is installed on.

Viewing http requests that happened
gb flag

Is there a log file where ubuntu stores all the http requests that come in? I need to view a request that happened yesterday, more specifically the body of that POST request.

And also if nothing is listening on that port would that be a problem? The port is open by the firewall there is just no application that is using that port. Would that be a problem when it comes to viewing the requests

I can achieve that at this moment, using netplan and a script to delete some routes, but want your help to understand if I can make it using netplan.

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.
